[Industrial applications]

 The present invention relates to a device for picking up potatoes that have been air-dried in the field onto the bed of a work vehicle.

[0002]

[Prior art]

 Conventionally, a potato picker has been commercially available as a device for picking up air-dried potatoes in the field, but the drawback of this device is that foreign matter is caught in the rotating disk of the device and it becomes unrotatable. There is a problem that the potato picked up by the rotating disc may be damaged. In order to solve this problem, the applicant of the present application has devised a potato pick-up device of Japanese Patent Application No. 1-70460. In the potato pick-up device described above, a plurality of pick-up rollers having the same driving rotation direction as the pick-up conveyer conveyor are arranged in parallel in front of the front end portion of the pick-up conveyor whose front side is inclined lower on the lower surface of the traveling machine body. It is constructed in parallel. By configuring the above-mentioned plurality of pick-up rollers to pick up the potatoes, the possibility that foreign matter is caught is reduced, and the problems that the picked-up potatoes are damaged are reduced.

[0003]

[Problems to be solved by the device]

 The above-mentioned potato pick-up device was able to solve the problem of trapping foreign matter and damaging potatoes.However, in the case of a downward-sloping field, the potatoes picked up on the pick-up roller return to the beginning of the digging conveyor. In some cases, there was room for improvement in this respect.

According to the present invention, the potato pick-up device as described above is provided with an auxiliary means for surely picking up the potatoes by the pick-up roller, so that the potatoes can be picked up reliably even in a downward slope field. The challenge is to be able to do so.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the potato pick-up device of the present invention is designed to drive in the same direction as the above-mentioned digging conveyor in front of the front end of the digging conveyor, which is installed with the front end of the traveling machine body tilted low. A plurality of rotating pick-up rollers are arranged side by side in a parallel manner, and a rotary brush that drives and rotates in a direction to scrape the potatoes placed on the pick-up roller toward the digging conveyor is arranged just above the pick-up roller. It was done.

[0006]

[Action]

 According to the above means, the digging conveyor, which is installed on the lower surface of the traveling body with the front end portion tilted low, and the plurality of pick-up rollers installed at the front end of the digging conveyor, remove the potatoes on the ground. Pick up and drive and rotate in the direction to convey to the end.

At the time of work, the traveling body is moved forward with the frontmost pickup roller slightly buried in the ground.

[0008] Among the potatoes that were air-dried as the traveling aircraft advanced, the potatoes that were completely exposed on the ground surface were picked up on the roller by the pick-up roller near the digging conveyor. Immediately after that, it is scraped by a rotating brush, placed on the start end of the excavation conveyor, and conveyed toward the end of the conveyor.

[0009] A potato partially exposed on the surface of the ground was dug up and picked up by a pick-up roller in the foremost part buried in the ground, and was put on a pick-up roller near the digging conveyor. After that, it is scraped toward the starting end of the digging conveyor by the rotary brush as described above.

[0010]

[Effects of the Invention] As described above, the present invention picks up air-dried potatoes in the field by a plurality of pick-up rollers juxtaposed in front of the front end of the digging conveyor. It is possible to reduce the problem of foreign matter being trapped or scratching the picked-up potatoes.In addition, by scraping the rotating brush installed directly above the pick-up roller, the potatoes on the pick-up roller can be reversed. Since it is possible to positively feed the digging conveyor to the starting end, air-dried potatoes can be reliably picked up even when working on a field on a down slope, for example.
