It is configured as follows.

[0006]

Problems to be Solved by the Invention
The root crop harvesting machine disclosed in No. 33 is capable of collecting a root vegetable body that has been pulled and harvested and subjected to leaf cutting in a container, and the container can be placed in a field. Although it can be performed, the root vegetables can be collected relatively easily. However, no particular consideration is given to the leaf cutting process in the harvesting unit, and a highly accurate leaf cutting process is required. There was room for improvement in harvesting.

The harvesting machine disclosed in Japanese Utility Model Application Laid-Open No. 6249917 allows an auxiliary worker on a machine towed and moved to select only non-defective root vegetables and collect the containers, thereby enabling continuous harvesting. Although it can be performed efficiently, this harvester also does not take into consideration the point of increasing the accuracy of cutting leaves in the harvesting section, and there is a point to be improved in practical use as in the previous example. In addition, by changing the attitude of the container base that receives the root vegetable body discharged from the end of the conveyor, the root vegetable body can be collected without damaging it. The cylinder must be operated, and if this operation is performed by an operator, it is troublesome. Further, if the operation is automated, the apparatus becomes complicated and expensive. In addition, because of the towing mobile type, the entire harvester including the towing vehicle such as a tractor is long and large in the front and back, and can be introduced into large farms, but can be effectively used in relatively small farms. It was impossible.

The harvester disclosed in Japanese Patent Application Laid-Open No. 64-16512 can continuously and efficiently perform high-precision integrated operations from extraction of root vegetables, leaf cutting, and recovery of root vegetables themselves after leaf cutting. In order to do so, it was not yet sufficient in terms of practical use, including the overall configuration of the harvester, and there was a point that had to be improved.

In other words, the roots of the root crops often extend greatly in the horizontal direction or around the periphery, and the leaves that are greatly collapsed or the leaves that extend greatly in the horizontal direction are pinched and conveyed to the left and right. In some cases, the leaves may not be properly introduced between the belts, and a part of the leaves may leak from between the left and right nipping and conveying belts. As described above, when a part of the leaf part is disengaged from the holding between the conveyor belts and is conveyed while protruding below the conveyor belt, in the subsequent positioning process, the leaf part protruding downward is left and right for alignment. The root vegetables are easily pulled out from the adjustment belt and protrude below the adjustment belt. When the height is aligned on the lower surface, the protruding leaves are pinched between the root vegetable body and the adjustment belt, and the root vegetable body does not come close enough to the adjustment belt. The leaves protruding from the belt are left uncut without being cut, and the remaining leaves need to be manually cut off again, resulting in low cutting performance in the leaf cutting process.

[0010] In addition, root vegetables in the field, the amount of leaves,
Cultivation area, such as length, extent of leaf, degree of side
It varies according to growing conditions such as harvest time, variety, etc.
It is important to implement high-performance leaf cutting that can cope with this.

Further, in the step of pulling out the root vegetables in the field with the sandwiching and conveying belt, the root vegetable pulling reaction force acts on the starting end of the sandwiching and conveying belt. Changes every moment due to the soil hardness and the like, and the effect of this causes a change in the pinching height position of the leaf portion, which deteriorates the accuracy of the cutting position of the leaf portion.

Further, in the positioning device, the root vegetable body is received on the lower surface of the adjustment belt so that the height of the root vegetable body is uniform, the cutter is disposed above the adjustment belt, and the leaf is easily gripped. The leaves had been cut in the state. As a result, it is difficult to cut the leaves at certain positions,
In addition, the leaves will remain for a long time in the root vegetable body that has been subjected to leaf cutting, and there will be almost no uncut leaves of the leaves, that is,
If you want to obtain a root vegetable body whose leaves have been cut at the boundary between the leaves and the upper end of the root vegetable main body, it is necessary to manually cut off the leaves remaining on the root vegetable body that has been mechanically harvested and collected. The harvester will not be used effectively.

Further, since the harvested root vegetables are taken back to a processing facility and subjected to processing such as sorting and washing, a harvesting machine of this type is provided with a reasonable arrangement configuration to improve the harvesting function and processing accuracy. Not only is it expensive, but also how to efficiently recover the root vegetable main body is an important matter.
The harvester disclosed in Japanese Patent Publication No. 12 cannot take such a point into consideration.

The present invention has been made in view of such a point, and it is possible to efficiently perform a series of efficient cutting of leaves from the raising and transporting of root vegetables, and to enable appropriate lifting, sandwiching and transporting. The root vegetable body can be harvested with high accuracy of the cutting position and the leaf can be cut with almost no uncut leaves. It is a primary object of the present invention to provide a riding type root crop harvester that is compact and has excellent workability, which can select and efficiently collect the root crops.

[Structure, operation and effect of the invention according to claim 1]

(Structure) The invention according to claim 1 is a soil breaker for loosening the soil near a root vegetable in a field, and an obliquely upward rearward from the vicinity of the ground in a posture in which a locking claw projects forward. A leaf pulling device that moves and pulls up the roots of the root vegetables in the field, a pinch pulling transport device that pinches and pulls the lifted leaves and hangs it to the upper rear, and a root vegetable leaf that is hung and transported A position aligning device that introduces the portion between the left and right guide portions and regulates the elevation of the root vegetable main body by the guide portion while the root vegetables are moving backward, and aligns the height thereof, and the guide portion of the leaf portion. A harvesting unit including a leaf holding and conveying device that holds the upper position and conveys the rearward, and a cutter that cuts a leaf of a root vegetable held by the leaf and holding device is disposed on one lateral side of the machine body. At the same time, board the front of the aircraft on the other side A rolling unit is arranged, and a sorting conveyor for placing and transporting the root vegetable main body released from the harvesting unit is arranged near and along the outer edge of the machine body, and at the rear of the machine body, conveyed by the sorting conveyor. A root vegetable main body recovery unit that accommodates the root vegetable main body that has been placed in the container is provided at the outer edge of the machine body, and the sorting conveyor is moved in the transport direction with the bar-shaped transport body arranged in parallel in the transport direction, and adjacent to the sorting conveyor. A container for sorting is formed between the rod-shaped carriers, and the container holder provided in the root vegetable main body recovery unit is supported so that the rear end side can move up and down, and the root vegetable receiving posture of the container can be changed. In addition, the rear end side of the container cradle is urged upward, and the container cradle is configured to move downward from the inclined posture in accordance with an increase in the weight of the mounted object. To.

(Function) According to the above configuration, before the leaf portion of the root vegetable in the field is held by the nipping / lifting / conveying device, the root portion is subjected to the lifting action by the locking claw of the leaf portion pulling device.
Occurrence of leakage of the leaf portion at the starting end of the nipping and pulling transport device is reduced. As a result, after that, when the leaf portion of the root vegetable that is suspended and conveyed is introduced between the left and right guide portions that align the height, a part of the leaf portion is not introduced between the left and right guide portions. There is almost no possibility that the leaves protrude downward, the leaves are properly clamped by the nipping and pulling conveyance device, the leaves are properly guided between the left and right guides, and the leaves leaking from the left and right are pinched. Leafs that are caught at the introduction portion to the guide portion and that the leaf portion is caught between the root vegetable body and the left and right guide portions to prevent an obstacle in height alignment are prevented, or that the leaf portion protrudes below the guide portion. It is not necessary to cut off the uncut leaves again by hand after the machine harvest.

Further, even if the rooting condition of the root vegetables or the hardness of the soil at the place where the root vegetables are planted changes, when the roots are pulled up from the field with the leaves being pinched by the pinch pulling and conveying device, Since the crushed body loosens the soil near the root vegetable body, the root vegetable is less resistant and the pulling resistance of the root vegetable is relatively stable, and the root vegetable body remains in the field and only the leaves are cut off and transported Then, the leaves that have been torn and conveyed may cause an adverse effect on the height alignment in the subsequent process, or the leaves may slip down due to the lifting reaction force acting on the starting end of the nipping / lifting / transporting device, and The adverse effects of, for example, nipping and transporting the leading end side are reduced.

The height of the root vegetable main body is aligned by the left and right guide portions, and the root vegetable is supplied to the cutter while maintaining the aligned height by the leaf holding device, and the leaf portion is cut by the cutter. The root vegetables whose leaves have been cut and separated are conveyed by a sorting conveyor and sent to a container on a container receiving tray. At this time, if the storage capacity of the root vegetable main body in the container is small, the container tray is at a high position with the rear end swung up, and the container supported by this container tray has a small head and the root vegetable body is The root vegetable body is smoothly dropped and stored in the container without damage. Then, as the capacity of the container increases, the cradle gradually moves downward against the upward biasing force, and the posture of the container is also swung down, and the container is fully used for collection. Is performed.

Here, the sorting conveyor is configured such that bar-like carriers arranged in parallel in the carrying direction are moved in the carrying direction and a separating gap is formed between adjacent bar-like carriers. Therefore, foreign substances such as garbage and mud conveyed together with the root vegetable body fall through the separation gap during this conveyance. In addition, since the sorting conveyor is arranged near and along the outer edge of the machine, an auxiliary worker outside the machine that follows the walking does not have any damage or cracks from the conveyed material on the sorting conveyor. It is possible to sort out and remove non-defective products, poorly grown products, and garbage that did not fall from the gaps, and reduce the mixing of defective products and the like into containers.

Further, since the container receiving stand is arranged so as to be located at the outer edge of the machine body, an auxiliary worker outside the machine which walks and follows can easily drop the fully lowered container onto the field. In addition to making it possible to replace the container with a new container, it is also possible to remove defective products and garbage that have entered the container as they are sequentially loaded into the container. As a result, mixing of defective products and the like into the container can be reduced.

(Effect) Therefore, according to the invention of claim 1, the function of the leaf pulling device prevents the leaf from being pinched and leaked at the start end of the pulling and nipping and transporting, and also avoids the shredding of the leaf and the like. The height adjustment function of the root vegetable body by the subsequent left and right guides can be properly performed, the leaves can be reliably cut at a fixed position, and highly accurate leaf cutting can be performed, excellent in practicality Root crop harvester can be configured.

Also, a leaf that is greatly extended in the lateral direction or a leaf that has fallen is pulled upward from the front of the start end of the nipping / pulling-up conveyance device by a locking claw protruding forward to secure an upright posture. By loosening the soil around the main body of the root crop, the pinch pulling and lifting device ensures accurate pinching of the leaves, soft pull-out, and transport in a stable posture, leaving uncut roots, cracks and scratches. In this case, the cutting height is constant and the cut edges are neatly aligned, so that the continuous operation from the extraction of the root vegetables to the cutting of the leaves can be performed efficiently and with high precision.

Moreover, by adopting the leaf holding and conveying device, the leaves can be cut while maintaining the height aligned by the left and right guides, and the disadvantages such as the root vegetables being displaced downward are eliminated, and the stability is improved. It is possible to reliably cut the leaves at a certain position, and it is possible to cut the leaves at a position very close to the root vegetable main body, that is, to cut the leaves at the boundary between the leaves and the upper end of the root vegetable main body. Can be collected in a leaf-cut state with almost no uncut portion.

In addition, a sorting conveyor capable of dropping and sorting foreign substances and a root vegetable main body collecting section are rationally arranged on the outer edge of the machine body, so that a defective product and dust can be collected with less contamination. Can be performed, and sorting and container replacement by auxiliary workers outside the machine that follow walking can be performed.
A compact harvester that enables the driver to board and drive, and the recovery work can be performed by an outside assistant who walks and follows. In addition, it was possible to obtain a root crop harvester excellent in practicality, which can be harvested in a small field, and can be effectively used by being introduced into a small field.
