Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a bean sorting device for sorting collected bean pods such as silk-pod beans, potato beans, soybeans, etc. according to their length.

[Conventional technology and problems]

Beans, a type of fresh food, are required to be sorted into large and small, long and short, and then shipped shortly after harvesting.However, unlike mechanically produced beans, their external appearance varies. Because it is a miscellaneous product, its weight is not constant, and expensive sorting equipment is not profitable, it is not possible to use normally used wind-powered sorting equipment or expensive sorting equipment that uses sensors, etc. Currently, the sorting is done manually by workers.

However, when manually sorting a large number of pea pods in a short period of time, it is a considerable burden on the worker, and the scratches caused by fingernails etc. during sorting may be the cause. There were problems such as a high rate of defective products.

In view of these problems, the present invention has been developed by placing a certain amount of pea pods in the supply container, which automatically and smoothly feeds them to the sorting section using shaking vibrations, resulting in highly efficient sorting. The purpose of the present invention is to provide an inexpensive sorting device that can meet the requirements for short-term sorting and shipping, and to reduce the burden on workers.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention applies rocking vibration to the top plate supported on the upper surface of the main body frame so as to be able to vibrate or swing freely, by means of changing an electrically driven rotational motion into a rocking motion. The main body frame and the supply side frame are connected to each other. and an electric motor supported by the supply side frame is used as a drive source to transmit rotational motion to the oscillating vibration mechanism section of the sorting device section,
It is characterized in that a tensile force adjustment member that is connected to the main body frame with the bottom surface as a base point and a fixed adjustment member that is connected to the supply side frame are attached to the bottom surface of the supply container. The details are as follows.
