Description

[Detailed description of the invention] The present invention relates to an improvement in a rocking device for a grain sorter.

In general, the grains of pigeon wheat and beans have an inverted spherical shape and are unstable on a flat plate, making them extremely susceptible to rolling. Grains typically differ in shape or elasticity compared to whole grains.

The present invention has the advantage of efficiently performing the rocking action and blowing action of a porous wall sorting plate with a corrugated surface that uses the differences in shape, elasticity, and specific gravity between intact grains and damaged grains with a simple structure. The aim is to develop and provide a new device.

The present invention will be explained with reference to embodiment figures. In Fig. 4, reference numeral (1) is a porous wall screening plate formed on a wavy surface (2), and the screening plate (1) is vibrated back and forth until it stops at the front, and a supply port (3) provided on the negative side thereof. The mixed grains supplied to the sorting plate (1) are separated into the front and rear, respectively, and flowed laterally from the grains to the complete grain outlet (4) provided in the floor section of the sorting plate (1). ), mixed grain outlet (5), damaged grain outlet (
6) are formed so as to discharge the sorted grains respectively.

Figures 1 and 2 show a grain sorting machine equipped with the above-mentioned porous wall sorting plate, in which the porous wall sorting plate (1), which has a supply port (3) on its negative side, is mounted at a gentle slope. A ventilation chamber (7) is provided in the upper part of the sorting plate (1), and a ventilation chamber (8) is provided in the lower part thereof to integrally form a sorting machine frame (9). 9
) A rocking mechanism (10) and a wind turbine box (1) are arranged in relation to each other, and the rocking mechanism (1 (1) swings the porous wall sorting plate (1), and the wind turbine box river ) to generate wind and blow it upward from the bottom surface of the sorting plate (1). That is, the lower part of the wind turbine box (11) fri is connected and fixed to the horizontal 1hi-shaped underframe (12) by a fastener (13), and a rotating shaft (14) is attached to the cylindrical body side.
A support rod (16) with a support shaft (15) is installed on the other side of the cylindrical body, and the wind turbine box (11) and the ventilation chamber (8) in the upper sorter frame are connected to each other in a wind tunnel. Connects to section (17) at the upstream. In addition, the swing mechanism (10) has upper supports (18) (19) (18) provided on the lower wall surface of the sorter frame (9).
(1,9) and the lower support (2+) (22) (21) (22) provided on the horizontal arm rod (20) (20) are connected to the elastic support rod ( 23) (24)
(23) are interconnected by (24), respectively,
Further, the - side end of the arm rod (20) is pivotally attached to the rotating shaft (14), and the other side end is attached to the support rod (16) via an angle adjustment device (25) consisting of a bevel gear and a screw shaft. ), and is integrally fixed to the load point (26) of the machine frame (9).
) and the eccentric shaft part (28) of the eccentric cam mechanism (27) are connected by a connecting rod (29), and the cam mechanism (27)
) The extension shaft (31) of the rotating shaft (15) is inserted into the shaft hole (row) of the rotating main shaft (see Fig. 1).
(82) is a metal fitting for fixing the rotating shaft, (blade) is a pulley incorporated in the cam mechanism, (34) is its heavy bell, and the rotating mechanism of this device is operated by an electric motor (a) to the wind turbine box. (At the same time as rotating the river general-purpose axle (36), the shaft (36) rotates the deceleration pulley (87),
7), the elevator pulley (88) and the pulley (38) of the cam mechanism (27) are formed to rotate in conjunction with each other, and (39) is the elevator, and (4,0) is the grain of the elevator. It's a tank.

Claim (3) provides that the - side end of the horizontal arm rod (20) is a shaft hole (41A) having a chive side structure.
(Since it is formed in 41BJ and is attached to the rotating shaft (14) so that it can be installed and removed freely, it is possible to simplify the assembly and disassembly of the swing mechanism and the replacement of parts, as well as to simplify manufacturing and processing. effective.

With the above-mentioned configuration, when raw beans are put into the supply section of the elevator (39) and the device is started, the grain tank (40
) onto the lower perforated wall sorting plate (1). The porous wall sorting plate (1) is vibrated back and forth by the swinging mechanism (Hl) so that the wavy surface (2) of the sorting plate stops at the front and vibrates back and forth.
In addition, on the porous wall surface, the wind generated in the wind turbine tube) is blown toward the ventilation chamber (7) via the ventilation chamber (8), so that the beans supplied to the sorting plate (1) are , a flat grain layer is formed while flowing down on the sloping wavy surface (2), and incomplete grains (damaged grains, half-split grains) with low specific gravity are destroyed by the blast action from the porous wall surface. As they float to the top of the grain layer, the complete grains with high specific gravity gather at the bottom of the grain layer, and due to the vibration of the mountain veins, the complete grains at the bottom of the grain bed are pushed forward and toward the higher side. The incomplete grains floating on the upper surface of the grain layer drift laterally to form a complete grain flux (P) (see Figure 4). The flow is biased in the direction to form a damage particle flux (FT), and each flux (P)
A mixed grain flux (Q) of complete grains and incomplete grains is formed between the grains (R), each of which flows to the bed section of the sorting plate, is separated and discharged. The swinging mechanism (10) and rotation mechanism of the swinging device of the present invention are driven by an electric motor (35) into a blade axle (36).
) is rotated to send the wind generated by the wind turbine box (11) to the sorter frame (9), and also to the elevator pulley (88) and the eccentric cam mechanism (27) via the deceleration pulley (87).
The pulley (88) for the elevator rotates in conjunction with the pulley (88), and the elevator pulley (88) performs a grain lifting action on the raw beans, and the pulley (wings) rotates. The connecting rod (29) is moved up and down in an obliquely upward direction via the eccentric shaft (public) provided in the connecting rod (27).

Therefore, the porous wall sorting plate (1) of the sorter frame (9) swings to perform the aforementioned sorting action.

As described above, in the swinging device of the present invention, the shaft hole of the rotating main shaft of the eccentric cam mechanism is fitted into the coaxial extension shaft to which one side end of the horizontal arm rod provided in the swinging mechanism is pivotally connected. Since it is inserted and mounted on the shaft, compared to conventional devices in which the crankshaft of the rocking mechanism is connected to a vibrating device with a separate drive unit, the device structure and rotation mechanism are extremely simplified, and manufacturing costs are significantly reduced. In addition to being inexpensive, the weight of the device is reduced to simplify transportation, installation, etc., and the rotating shaft and angle adjustment device are provided on both sides of the body of the exhaust chamber, respectively, so that both ends of the horizontal arm rod are provided. As a result, the entire device is compact and compact, and operation and angle adjustment of the sorting plate are also simplified, greatly improving work efficiency and ensuring quality selected grain at all times. Moreover, it has the advantage of being able to be mass-produced smoothly and quickly.
