Description

[Detailed description of the invention] The present invention relates to a mechanism that is installed below the receiving net of the handling barrel to separate grains from impurities in an axial flow threshing machine used primarily for threshing soybeans. . The axial flow method is a method in which the unthreshed grain rods input from the supply port A are moved toward the discharge port B by the rotation of the handling drum and the action of the handling blades, and are threshed while being moved in the axial direction of the handling drum. It is.

To explain the embodiment of the present invention in detail with reference to the attached drawings, below the receiving net 2 of the handling cylinder 1, there is an upper plate 3 having approximately the same length in the axial direction of the handling cylinder 1, and from the upper plate 3. A lower plate body 4 having a short length is arranged in two stages, upper and lower, and a plurality of narrow grain passage holes 5 are bored in the upper plate body 3 so as to be orthogonal to the axial direction of the handling barrel 1. In addition, several grain guide wires 6, 6 are arranged in the axial direction of the handling cylinder 1, and an endless transfer mechanism 7 of a belt or chain running in the axial direction of the handling cylinder 1 is installed on the upper plate 3.
The endless transfer mechanism 7 is equipped with a grain pushing member 8 that rubs the upper surfaces of the upper and lower plates 3 and 4, respectively. In addition, numeral 9 is an unsorted grain flow down plate, 10 is a blower, 11 is a sorting conveyor, 12 is an auxiliary sorting mechanism, 13 is a sorting grain collection tube, and 14 is a grain.

Next, I will explain the process of threshing soybeans from unshelved grain rods using this device, sorting out foreign substances such as lees and twigs that were mixed in during threshing, and sorting and recovering the soybeans.
When unthreshed grain rods are fed into the axial flow threshing machine through the supply port A, the unthreshed grain rods move toward the discharge port B side, and due to the rotation of the handling drum 1 and the action of the handling blade 1',
During the process of transport in the axial direction of the grain rod, grains are shredded, and large foreign objects that cannot pass through the mesh of the grain rod and receiving net 2 are discharged from the discharge port B to the outside of the machine. However, the soybeans and lees that passed through the mesh of receiving net 2,
Small foreign objects such as twigs fall onto the upper plate 3 and are pushed by the grain pushing member 8 attached to the belt 7 and sliding on the upper plate 3. The grains fall downward from the width grain through holes 5, 5, some of them directly fall onto the unsorted grain flow lower plate 9, and the rest fall onto the lower plate 4, and the grains are transferred to the grain transport on the return journey. Unsorted grains are pushed by member 8 and flow down plate 9
The normal soybean grains that have fallen to the top are sorted and stored in the grain sorting and collection cylinder 13, while foreign substances such as small and light shavings, twigs, and leaf pieces are transferred to the sorting conveyor 11 where they are collected by the wind pressure of the blower 10. This causes it to be blown up and ejected from the aircraft. However, the grain guide wires 6, 6 formed on the upper surface of the upper plate body 3 are used to prevent long grain waste, twigs, etc. from falling onto the unsorted grain flow down plate 9. In other words, most large foreign objects are Although the receiving net 2 can prevent it from falling downward, some foreign objects may pass through the receiving net 2 even though they are long, and the long foreign objects are so heavy that they cannot be sorted out by the blower 10, so the upper plate A narrow passage is formed on the body 3 by the grain guide wires 6, and foreign objects shorter than the interval between the grain guide wires 6, 6 fall through the grain through holes 5, 5, and pass through the grain guide wires 6, 6. Foreign matter that is longer than the interval is discharged out of the machine by the grain pushing member 8.
In addition, an auxiliary sorting mechanism 12 installed on the outside of the handling cylinder 1
is intended to recover some of the grains ejected from the handling barrel 1, and the grains are returned to the interior of the machine and are sorted through the lower plate 4. The soybeans thus threshed by the axial flow type threshing machine are actively pushed by the grain pushing member 8 into the grain passage holes 5, 5 on the upper plate 3 disposed in the lower part of the receiving net 2. Further, a part of the unsorted grain falls onto the lower plate 9 through the lower plate 4, and the wind pressure from the blower removes the ground waste and other small foreign substances mixed in during threshing, and the grain is normal. This is an extremely useful and advanced technical device that automatically separates grains and foreign substances, eliminates the need for re-sorting, and improves work efficiency.
