Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for adjusting the amount of grain discharged from a oscillating sorter.

A sorting plate formed on a rough surface is swung diagonally up and down, and mixed grains of paddy and brown rice are supplied to the sorting plate, so that bundles of brown rice grains are placed on the shaking side of the plate, and paddy grains are placed on the opposite side of the shaking direction. The bundles are made to drift, and the mixed grain bundles of paddy and brown rice are flowed into the middle part of the grain bundles and flowed down to the grain discharge gutter provided at the end of the sorting board, and each of the grain bundles is separately introduced into the discharge gutter. In a sorting device equipped with a guide wall plate, the drifting state of the various grain bundles changes slightly depending on the amount of grain on the sorting plate surface, so the guide wall of the grain discharge gutter can be moved and adjusted in a timely manner. It is necessary to reliably separate and introduce the various grain bundles into their respective outflow channels. The conventional movement adjustment of the guide wall includes:
A photoelectric detection device is integrally attached to the guide wall to optically detect the mixed state of foreign grains among the grains flowing down the wall, and an adjustment screw shaft is connected to the guide wall plate based on the detection signal. The sorting disks of huller sorting equipment in large facilities are equipped with an automatic adjustment device that rotates forward and reverse. In addition to visual detection, the movement of the guide wall plate is manually operated directly during the operation of the sorting panel, so the adjustment work is extremely dangerous and has disadvantages such as often causing adjustment errors. It had

In view of the above points of the present invention, in adjusting the movement of the guide wall plate by manual operation, the danger of the above-mentioned adjustment work is completely eliminated and safety is achieved, and the movement can be performed with high precision without inducing adjustment errors. To develop a convenient device which easily and safely ensures a high rate of discharged grain in the grain oscillating sorting action by easily carrying out the adjustment by a wall plate movement adjustment device. This is what we intend to provide.

The present invention will be explained with reference to embodiment figures. In Fig. 2, reference numeral 1 denotes a sorting board with a rough surface forming a frictional resistance that can guide rice grains. Different types of grains, such as mixed grains of paddy and brown rice, are supplied from the supply conveyor 2 in the outflow direction C, and while flowing, brown rice grain bundles P with a small friction coefficient are placed on the shaking side H, and brown rice grain bundles P with a large friction coefficient are placed on the opposite side L. A grain discharge gutter 3 provided at the edge of the sorting board 1 is used to concentrate the rice grain bundles R in a concentrated manner, while flowing the three types of grain bundles, the mixed grain bundle Q, in the direction C.
The grain bundles are separately introduced into respective outflow paths 6, 7, 8 for brown rice, mixed grains of paddy/brown rice, and paddy by means of guide walls 4, 5 that move and adjust along the edge of the plate. It has been formed. Next, in FIG. 2, the sorting board 1 is an oscillating sorting machine that is integrally formed with a grain discharge gutter 3 provided at the end of the discharge side board and a vibration mechanism 9 provided at the lower part thereof. On the bottom surface of the sorting board 1, a pair of upper fulcrum shafts 10, 1 are provided at the front and rear positions.
A pair of lower fulcrum shafts 13 and 14 are respectively installed at the front and rear of bending rods 12 and 12 which are horizontally hung on the lower part of the rods. Shafts 13, 14 and upper fulcrum shafts 10, 1
1 are connected by a plurality of connecting rods 15..., the lower fulcrum shaft 13 is rotatably attached to the upper end of the base 16, and the center of each variable angle rod 12, 12 is provided with an adjustment rotation. It is supported by an angle adjustment device 18 with a moving rod 17. Reference numeral 19 denotes a wall board movement adjustment device provided on one end side of the bending rod 12. The adjustment device 19 has a long adjustment groove 20 in the rod portion, and an adjustment device movably inserted into the long groove 20. A fixing screw 21 is provided, 22 is an eccentric rotating device connected to the passive part of the sorting board 1 by a connecting rod 23, and 24 is an electric motor thereof. A first wire engagement part 25 is provided on the extension of the upper fulcrum shaft 10 of the vibration mechanism 9, and a second wire engagement part 25 is provided on the extension of the lower fulcrum shaft 13 provided on the lower bending rods 12, 12. A joint part 26 is provided, and the adjustment fixing screw 21 of the wall plate movement adjusting device 19 and the guide wall plate 4 movably erected in the discharge gutter 3 are attached to both the engaging parts 25 and 26. They are connected by a suspended wire 27, and 28 is an elastic spring provided on the opposite side of the guide wall plate 4 from the wire.
9 is a wire locking shaft fixed to the guide wall plate surface.

With the above-mentioned configuration, the mixed grains of paddy and brown rice supplied to the sorting board 1 are moved to the front side of the sorting board 1 as described above by the swinging motion of the sorting board 1 mounted in an inclined manner. In addition, the paddy is diverted to the rear, and the mixed grains of paddy and brown rice flow in the middle part, and each grain bundle P, Q, R is distributed from the horizontal board edge to each outlet channel 6 inside the grain discharge gutter 3. , 7 and 8 are separated by guide wall plates 4 and 5 and flow down, respectively. At this time, if the number of grains on one side of the sorting board is less than the reference grain amount, the width of the grain bundle P of the brown rice is reduced and some of the mixed grains flow down to the brown rice outflow path 6 and mix therein.

Therefore, in this device, the moving state of the brown rice grain bundles on the sorting board 1 is visually detected, and the fixing screw 21 of the non-vibrating wall plate movement adjustment device 19 is loosened to move the brown rice grain bundles forward by the amount that the brown rice grain bundles have moved. fixing screw 2
1, the wire 27 moves forward and the elastic force of the elastic spring 28 of the guide wall plate 4 causes the wall plate 4 to move a predetermined length to the lower side. After adjusting and checking,
Immediately screw in the fixing screws 21 to fix the guide wall plate 4 and adjust the guide wall plate 4. Therefore, the danger of adjustment work and adjustment errors caused by adjusting the movement of the swinging guide wall plate of the sorting board 1 as in the conventional device can be completely prevented, and highly accurate movement adjustment can be ensured. It is possible to carry out the method, and has the effect of easily and safely securing a high rate of grain discharge.

According to the second aspect of the present invention, the angle adjustment rod is equipped with an angle adjustment device, so that the angle of inclination of the wall plate movement adjustment device and the sorting board can be adjusted simultaneously by adjusting the angle of the angle adjustment rod. This has the effect of simplifying the adjustment work and improving the work efficiency.
