[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a bean dehulling machine used for harvesting beans such as soybeans and red beans.

[0002]

[Prior art]

 Shredding machines for dehulling beans, including soybeans and red beans, are mainly classified into traveling types and fixed types.Basically, the seeds are supplied by a pick-up device or manually. It is well-known that the pods are fed to the shedding section through a feeding section, and the grains, the husks, the stems, and the earth and sand that are shattered in the shedding section are sorted in the sorting section. is there. Then, only the selected grain is transported to the hopper or the harvest bag by the grain transport unit, and the sediment, bean husks, stems and leaves are discharged out of the machine.

[0003] By the way, in harvesting beans, it is basically preferable to dry the cut stems and pods to a certain extent. Tend to harvest beans early. However, in this early harvest, it is often the case that the sediment attached to the mown beans and stems is not completely dried, so that the adhered sediment cannot be completely wiped out and the residual sediment is being removed. There is a possibility that the particles adhere to the seeds and generate contaminants. The occurrence of this pollutant degrades the legumes and greatly affects the producer's income.

[0004] In addition, weed removal is an important work in growing crops, and this removal work is extremely important in growing crops, but on the other hand, it is extremely laborious for producers. For this reason, weeding may be performed by spraying herbicides. However, it goes without saying that such herbicides may have an adverse effect on humans who consume soil and crops. One of the causes of this weed is that seeds of weeds that are harvested together with crops are sown in fields, as well as flying weeds. For example, in the harvesting of beans using the above-described graining machine, the sediment, bean hulls, stems, leaves, and weeds separated from the grains are discharged outside the machine, so that the seeds of the weeds adhering to these are removed. Will be sown in the field, and as a result, the seeds and the flying seeds will grow, and weeds will grow all over the field. This weed is weeded at the time of seedling planting and sowing.However, as mentioned above, weeding work is heavy labor, and even during weeding, seeds are sown in the field, which grows together with crops. Weeds must be weeded.
