Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a swing adjustment device in a grain swing sorter.

That is, grain rocking involves separating and sorting grains by swinging a grain sorting plate having a rough surface and tilting both vertically and horizontally diagonally up and down in the horizontal direction, and causing the grains to flow vertically on the grain sorting plate. In the sorting machine, only the swing angle on the swinging side in the horizontal direction of the grain sorting plate is configured to be freely changeable and adjustable, in order to optimize the separation and sorting of grains flowing vertically on the grain sorting plate. In particular, it is an object of the present invention to provide a grain shaking sorter which can perform the sorting with good sorting performance by adjusting the separating and sorting action on the shaking side where brown rice is selected and which can be carried out suitably.

Next, the embodiment diagrams shown in the drawings will be described.

FIG. 1 shows a top view of the grain oscillating sorter, in which a plurality of rectangular grain sorting plates 1 with rough surfaces are superimposed, each grain sorting plate 1
is inclined in both the vertical direction Y and the lateral force direction A brown rice receiving trough 5, a mixed rice receiving trough 6, and a paddy receiving trough 7 are arranged side by side on the lower outer side of the vertical Y-inclined lower end of the grain board 1 with respective partition plates 8, 8 interposed therebetween. The structure is the same as the conventional structure.

The upper part of the swinging support rod 2 tilted toward the lower side of the inclination is rotatably connected to the lower side of the lower support frame 9 in the lateral force direction X of each grain sorting plate 1 through a pin 10, and Support rod 2
The lower part of the swing arm 13 is freely pivoted to the lower frame 11 side via a pin 12, and one end side of a swing arm 13 is freely pivoted via a pin 14 to the middle part of the swing support rod 2. Connect and drive part 15
The eccentric wheel 16 to be rotated is fitted to the other end side of the swing arm 13, and the swing of the swing arm 13 causes the swing support rod 2 to horizontally move each grain selection plate 1 at a predetermined swing angle θ1. It is installed and configured so that it can be swung diagonally up and down in the force direction X.

Further, on the upper side of the lower support frame 9 in the lateral force direction X of each grain sorting plate 1, the upper part of the swinging support rod 3 tilted to the lower side of the inclination is freely connected to the upper part of the swinging support 3 via a pin 17. The pin 18 that pivotally supports the lower part of the support rod 3 and the support part of the pin 18 are connected to the frame 1
The grain selection board 1 is operable by a threaded rod 21 with a bundle 20 so that it can be moved and fixed along the circular arc elongated hole 19 in the grain selection board 1, but the inclination angle α of the grain selection board 1 in the lateral force direction X remains unchanged. The arc elongated hole 19 is shaped to form a concentric circle centered on the pin 17, and the swing angle θ1 of the swing support rod 2 is
It is installed so that the swing angle θ2 of only the swing support rod 3 can be changed and adjusted without changing the swing angle θ2.

In other words, the rocking angle θ2 on the rocking-up side in the lateral direction of the grain selection board 1
It is constructed so that only the parts can be changed and adjusted freely.

Two of the above-mentioned swing supports 2 and 3 are assembled on the upper and lower sides of the inclination in the vertical direction Y, respectively.

Therefore, during the sorting work, each grain sorting plate 1 is connected to each swinging support 2.
, 3, the swinging arm 13 swings horizontally and diagonally up and down with a swinging angle θ1 on the swinging downward side and a swinging angle θ2 on the swinging upward side. The mixed rice fed onto each grain sorting plate 1 flows in the vertical direction Y inclination lower side and in the horizontal force direction The paddy is separated and sorted into layers on the shaking side, and the brown rice falls into the brown rice receiving trough 5, the mixed rice falls into the mixed rice receiving trough 6, and the paddy falls into the paddy receiving trough 7 and is taken out.

In this state, when the variety of mixed rice fed onto the grain selection board 1 changes, a change occurs in the surface friction coefficient and specific gravity, and the upper side of the slope of the grain selection board 1 in the lateral force direction In other words, on the shaking side, the pushing action of the grain becomes strong, and the brown rice violently collides with the side wall of the grain selection plate on the shaking side and rebounds to the shaking side, or even the paddy enters the shaking side and becomes separated. If the sorting action is to be inhibited, operate the bundle 20 and move the pin 18 to the swinging side while aligning the position of the pin 18 with the circular arc elongated hole 19, and the swinging angle θ2
pin 18 becomes small, weakening the pushing force toward the shaking side, and when the brown rice is not pushed to the shaking side and does not form a separated layer.
When the position is moved to the opposite side from the above, the swinging angle θ2 increases and the pushing force toward the swinging side is strengthened to correct the separating and sorting effect of brown rice and paddy to the best condition.

In this way, the present invention separates and sorts grains by swinging the grain selection plate, which has a rough surface and is inclined both vertically and horizontally, diagonally up and down in the horizontal direction, and flows the grains vertically on the grain selection plate. In this grain oscillating sorter, only the oscillating angle on the oscillating side in the lateral direction of the grain sorting plate can be freely changed and adjusted without changing the lateral inclination angle of the grain sorting plate. Even if the surface friction coefficient and specific gravity change, such as when the type of grain fed onto the grain selection board changes, the brown rice on the grain selection board can be easily removed by simply changing and adjusting the rocking angle on the rocking side. Separation and sorting of rice and paddy can be done in the best condition.

In particular, since the rocking angle on the shaking side where brown rice is selected can be freely changed and adjusted, the rocking direction in which the grain selection plate is swung diagonally up and down on the shaking side changes and the grain selection plate on the shaking side is changed. The separation and sorting condition can be immediately and easily corrected, and a simple structure can be provided that does not reduce the separation and sorting ability and does not mix paddy into the brown rice, and has the advantage of being suitable for implementation. .
