Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a foliage processing device in a harvester for harvesting underground rhizome crops. This invention relates to a foliage processing device that enables efficient harvesting by forcibly separating and discharging unnecessary foliage to the outside of the harvester when harvesting crops (hereinafter simply referred to as agricultural products).

[Conventional technology]

Traditionally, when harvesting crops such as this type of potato, the stems and leaves are first harvested and then the crops are dug up using a digging machine, or the crops are dug up without cutting the stems and leaves, and then the stems and leaves are manually removed. There was a method to remove it.

However, these harvesting methods have the disadvantage that the harvesting operation takes time and the efficiency of the operation is reduced.

On the other hand, harvesting machines equipped with foliage processing devices have recently been put into practical use, but there is a gap between the mechanism that separates the crops from the foliage, resulting in a large drop in height and a large movement range for the crops. This had the disadvantage of doubling the damage to crops.

For example, in the conventional example shown in FIG. 5, agricultural products 5 are transferred from a pick-up conveyor 1 through a foliage processing device 2 to a conveyor 4 equipped with a rotary bucket 3. Between the foliage processing device 2, especially the foliage processing device 2
The head difference a between the conveyor 4 and the transport conveyor 4 increases. For this reason, the crops 5 are often damaged, and the crops 5 are discharged from the sorting conveyor 6 into the tank 7 and harvested.
Increasingly, there are many products whose value has decreased.

Furthermore, the conventional example shown in FIG. 6 is different from the above conventional example.
Although the installation location of the foliage processing device 8 is different, the head a′ between this foliage processing device 8 and the conveyor 6 is still large, and there is no mechanism to reduce damage to the crops 5, which has the disadvantage of causing a lot of damage. Ta.
