Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a harvesting machine, for example, one for digging and harvesting onions.

Technical background of the invention and its problems Conventionally, onion harvesting machines have been used, for example, to dig up onions, transport them backwards on a conveyor, remove the stems and leaves from the onions, and transport the onions into containers, etc. There is a structure that transports it towards.

On the other hand, it is desirable to harvest onions all at once during the appropriate harvesting period, but this is difficult if the area is large.

Therefore, as a means of preventing secondary growth of onions and deterioration of onion quality, we cut the roots of onions.
A so-called pre-treatment process is often performed to lift the onions out of the ground. The onions are then harvested using a harvesting machine, but in that case, the onions have been cut at the roots and are floating, so there is no resistance against the excavation body, and there is a tendency to push the onions forward. There is a problem in that the onions are difficult to swallow and are difficult to transfer smoothly to the rear.

In addition, when harvesting at the appropriate harvesting time, onions have roots in the soil, so they can be transferred relatively smoothly to the conveyor, but because the soil is hard, even the soil can transfer to the conveyor. If the soil is not properly sieved by the conveyor, the soil will mix with the foliage, and this will wrap around the tapping rollers of the foliage processing device, resulting in a decrease in the foliage removal ability.

Purpose of the invention The present invention improves the swallowing of onions when harvesting onions after pre-treatment work and allows them to be smoothly transferred to the rear. The purpose of this is to prevent soil from being crushed and transferred as much as possible, and to prevent soil from degrading the foliage processing ability of the foliage processing device.

Summary of the invention This invention consists of a main body frame, an excavation body protruding from the front lower part of the main body frame, and an excavation body connected to the rear part of the excavation body, which transports the harvested material to the rear while sieving off soil. A conveyor, and a foliage processing device connected to the rear of the conveyor to remove foliage from the harvested material and convey the harvested material to the rear, the excavation body being curved toward the front of the mounting plate.

When harvesting onions in a field where pretreatment work, that is, onion root cutting work has not been performed,
The tip 10 is inverted, and the mounting plate 12 of the tip 10 is fixed to the mounting frame 9 with the curved working part 13 facing downward.

Next, when the engine 3 is activated, the endless track belt 2 is driven and the harvester runs, and the onions as a harvested product are dug up one by one with the tip 10 set at a predetermined digging height. The relatively hard soil is crushed and moved forward by the curved working part 13, and each of the dug up onions is transported to the first stage which is being rotated in conjunction.
The soil, which has been crushed into relatively small pieces by the first conveyor 8, is conveyed while being shaken off, and is further conveyed sequentially from the discharge end to the second conveyor 16, which is rotating in conjunction. The leaves are lifted up and conveyed by the second conveyor 16 and are sequentially carried from the upper discharge end via the chute 29 onto the foliage processing device 39 which is driven in conjunction. The onions are transported by the smooth rollers 37 and the tapping rollers 38, which are rotated in opposite directions of each set of the roller group of the stem and leaf processing device 39, and remove the stems and leaves attached to the onions. The onions are rotated and separated while being transferred to the rear, and are sequentially stored in a bucket 51 located at the lower part of the rotation of the lifting conveyor 46, and these onions are sequentially lifted as the lifting conveyor 46 rotates. When each bucket 51 containing onions is located at the upper part of the rotation of the lifting conveyor 46, each bucket 51 is inverted so that its opening faces downward, and the onions stored through the opening are sorted while being rotated in conjunction with each other. They are sequentially carried into the carrying section of the conveyor 55. Then, the onions carried into the carrying-in section of the sorting conveyor 55 are sorted and conveyed forward again by the rotating operation of the sorting conveyor 55, and then transferred to the loading conveyor 6, which is rotated in conjunction with the carrying-in section from the carrying-out section at the front end.
2, and from this loading conveyor 62, they are sequentially loaded onto the loading platform of an agitating vehicle such as a tractor or trailer that agitates relative to the harvesting machine, and are harvested.

In this way, onion harvesting work can be performed sequentially and continuously.

Next, when performing pre-processing work, that is, harvesting onions in a field where onion root cutting work has been performed, the tip 10 is inverted, and its curved working part 13 is turned over.
The mounting plate 12 of the tip 10 is fixed to the mounting frame 9 with the tip facing upward.

As a result, as the harvester runs, as described above, each cut onion is attached to each cutting edge of the tip 10.
4 and are successively guided into the curved working part 13, so that each onion is
Even if the roots are cut and there is no resistance, they are not pushed forward, but are successively swallowed by the tip 10 and smoothly conveyed to the first conveyor 8. Then, the onions are conveyed backwards while being sieved with soil, the leaves and stems are removed by a foliage processing device, and the onions are stored in the loading platform of an agitating vehicle, a container, etc. after undergoing the same operation as described above.

Effects of the invention According to the invention, the digging body protruding from the front lower part of the main body frame has a curved working part in the front part of the mounting plate, and a cutting edge at the tip of this working part. Since this excavation body was attached so that it could be turned over as appropriate so that its working part faced upward or downward, by installing this excavation body with its working part facing upward, it could be easily used in the field after pretreatment work. When harvesting onions, the onions are easily swallowed, the onions are not pushed forward, and therefore the onions can be transferred smoothly backwards, and the digging body is arranged so that its working part faces downward. By installing it in the same condition, when harvesting in a field where no pre-treatment is performed, onions are dug up and the soil is reliably crushed.Therefore, it is possible to prevent soil transfer as much as possible, and to remove the foliage from the foliage processing device using soil. Decrease in processing capacity can be prevented.

Therefore, by changing the direction of the excavation body up or down depending on the work conditions, the overall work accuracy can be improved.
It is possible to improve efficiency and is also economical.
