Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an onion harvesting machine.

(Conventional technology) Conventionally, onion harvesting machines, such as the Jikaisho
As described in Japanese Patent No. 59-26914, a conveyor for conveying onions is provided at the rear of the digging blade, and a foliage processing device is connected to the discharge end of this conveyor via a guide member. A structure in which a plurality of feeding bodies each having a plurality of radially protruding feeding claws for feeding onions carried out from the carrying-out end of the conveyor to the stem and leaf processing device are rotatably arranged side by side at intervals in the axial direction on the member. Are known. Then, the onions are conveyed by the conveyor while sieving off the soil, and the onions carried out from the conveyance end are sent out by each sending body on the guide member and carried onto the foliage processing device. At this point, the onion is conveyed backwards while its stems and leaves are cut.

(Problems to be solved by the invention) In the structure described in the above-mentioned publication, since the feed body having a plurality of feed claws is arranged in parallel in the axial direction facing the discharge end of the conveyor, each feed Onions that are irregularly carried out from the delivery end of the conveyor fall onto the feed claws of the conveyor body, and the onions are often damaged by the feed claws, and onions also fall between the feed claws of the feed body. In some cases, the onions are thrown toward the steeply sloped part of the guide member due to the rotation of the feeder, and the impact often damages the onions.Especially on slopes, harvesting operations should be carried out in the direction of the contour line. Since the harvester is advanced at an angle, the onions are carried out from the conveyor's delivery end.
Onions are likely to be carried out in a lopsided state on each feeder located on the lower side of the inclination direction, and the onions are often further damaged by these feeders. There is a problem in that the foliage is carried into the loading section in a biased manner toward the lower side in the sloping direction, making it easy for the foliage processing device to make errors in foliage processing.

Therefore, the present invention was developed in view of these points, and is located outside the delivery end of the conveyor to reliably receive the onions being delivered from the delivery end of the conveyor without damaging them, and These onions can be distributed in the width direction and guided onto the chute, and these onions can be carried into the loading section of the foliage processing device while being dispersed in the chute without being biased. It is an object of the present invention to provide an onion harvesting machine that can reliably perform foliage processing by effectively utilizing the foliage processing surface of a processing device, and can prevent processing errors.

(Means for Solving the Problems) The onion harvesting machine of the present invention includes a conveyor that conveys the dug onions, and a stem and leaf processing device that is installed at the rear of the conveyor and cuts the stems and leaves of the onions while conveying the onions. A plurality of guide rods are provided between the foliage processing device and the discharge end of the conveyor so as to be inclined backwardly and guide the onions to the foliage processing device at predetermined intervals in the width direction. a chute, and a plurality of chute arranged opposite to the discharge end of the conveyor, the onions being discharged from the discharge end of the conveyor in the width direction being distributed between the respective guide rods of the chute and guided onto the chute. having a guide recess, and
The guide body includes a guide body in which the lower end of each guide recess is exposed between each guide rod.

(Function) In the onion harvester of the present invention, each onion that has been dug up is carried into the carry-in part of the conveyor and conveyed backward, and is thrown toward the guide body from the carry-out end of the conveyor, and is thrown by the guide body. It can be accepted temporarily. Then, each onion is neatly distributed in each guide recess in the width direction of the guide body, and is guided downward along each guide recess, and from the lower end of each guide recess to each guide rod on the chute. They are transported in a dispersed manner.

The onions carried onto this chute are guided by their respective guide rods and slid downward while being sieved with soil, and are sequentially carried into the carrying section of the foliage processing device while being dispersed. Further, each onion that is sequentially carried into the loading section of this foliage processing device is conveyed rearward while its foliage is gradually led out below between the foliage processing rollers,
The foliage is cut by a foliage processing roller, and the cut foliage is dropped, and each onion is conveyed as it is and discharged from the discharge end.

In this way, due to the dispersion and alignment action of the guide body and chute, onions are transported onto the loading section of the foliage processing device in a leveled manner without being concentrated or lopsided in one place.
