Description

[Detailed description of the invention] The present invention is a dispensing device which is attached above the oscillating sorting plate integrally with the oscillating sorting plate and reciprocates in the vertical direction to feed grains to the oscillating sorting plate. The present invention relates to a grain distributing device for a multi-stage oscillating sorter, characterized in that the upper part of the box is detachably attached to the lower part of the box.

In a multi-stage oscillating sorter, when the number of grains to be sorted becomes small near the end of sorting, the machine switches to sorting using only the uppermost sorting plate. This was done by blocking all the grain feeding ports, except for the grain feeding port that communicates with the uppermost sorting plate, with continuous plates or the like.

However, gaps were often created at the contacts during the assembly stage, making perfect connection difficult.

Therefore, the inventor, applicant, etc. opened the grain drop opening above the grain supply side of the rocking sorting plate, provided a box below the drop opening, and configured the bottom plate of the box to be openable and closable. However, when only the uppermost sorting plate is used, we considered opening the bottom plate of the box so that the grains from the grain drop opening would fall directly onto the uppermost sorting plate.

However, this method also has problems.

In other words, in the above method, in order to prevent the grains that fall directly from the grain drop opening onto the topmost sorting plate from scattering outside the sorting plate, the dropping opening must be as close to the sorting plate as possible. Accordingly, the box body is placed closer to the sorting plate.

For this reason, even though the grain drop opening is the best place to take out the grain remaining in the machine after sorting, it is not possible to insert a residual grain receiver such as a winnow under the box. The residue must be picked up little by little, making it extremely troublesome to dispose of the residue.

In the above method, the distance between the box body and the sorting plate is widened,
It may be possible to solve the problem of the height of the grain droplet during sorting when only the topmost sorting plate is used by making the grain drop tube telescopic, but this would increase the height of the oscillating sorter itself. This drawback makes it difficult to adopt.

The present invention has been developed in view of the above points, and its structure will be specifically explained below based on the drawings showing the embodiments. 1 is a structure in which the swinging sorting plates 2 are stacked and fixed in multiple stages, not shown in the drawings. This is a multi-stage swing sorting machine configured to swing diagonally up and down as shown by arrow AB using an eccentric mechanism.

This oscillating sorter 1 is equipped with a discharge port 4 partitioned by two movable partition plates 3 on the lower side (grain discharge side), and each of the sorting plates 2 on the higher side (grain supply side). The grain distributing device 5 is provided for distributing and supplying grains to the grains.

The distribution grain device 5 is integrated with the swing sorting plate 2 below the grain drop pipe 7 of the supply hopper 6 which has a grain fall port 8 above the grain supply side of the swing sorting plate 2. A box body 9 is attached to the box body 9 to reciprocate diagonally up and down, and a partition wall 11 divides the bottom plate 10 of the box body 9 on the lower side of the transport side to form a plurality of equal grain feeding openings 12. While the grain openings 12 are connected to the respective sorting plates 2, these grain feeding openings 12
A cylindrical rotating body 13 having a circular cross-sectional shape with a large number of small protrusions 14 around the periphery is placed on the upper side of the bottom plate 1.
It is mounted at an appropriate distance from the surface of the grain feeding port 12 so that the grains being oscillated and transferred toward the grain feeding port 12 can be freely rotated by repeatedly colliding with the small protrusions 14.

Further, the box body 9 is divided into an upper transfer portion 9a and a lower transfer portion 9b by pressing a button toward the lower side of the transfer from the position where the grain drop opening 8 faces when the box body 9 is swung to the maximum in direction B. death,
A fitting part 15 provided at the lower part of the bottom plate 10a of the upper transfer part 9a and fitted with the bottom plate 10b of the lower transfer part 9b, and a fitting part 15 on the inner surface of the side plate 16a of the upper transfer part 9a and the side plate 16b of the lower transfer part 9b. Each is fixedly installed and transfers upper part 9
The hook 18, which is rotatably attached to the outer surface of the side plate 16b and the engagement pieces 17a and 17b1 that come into contact with each other when the lower transfer portion 9b is fitted and attached, and the hook 18 that is rotatably attached to the outer surface of the side plate 16b, is fixed to the outer surface of the side plate 16a. The upper transfer portion 9a is transferred to the lower transfer portion 9b by a fixing means that is hooked on the provided receiver 19.
It is configured so that it can be attached to and detached from it.

However, the structure for attaching and detaching the upper part of the box to the lower part of the box is not limited to the structure of the above embodiment.
Of course, other structures may also be included as long as the purpose of attachment and detachment can be achieved.

Since the present invention has the above structure, when grains are fed from the hopper 6, they fall from the drop port 8 of the grain drop pipe 7 onto the bottom plate 10 of the box body 9, causing the rocking sorter 1 to swing. The grains are oscillated and transferred as the grains move, and are evenly distributed over the entire surface while receiving a leveling effect from the surface of the rotating body 13, and enter the grain feeding opening 12, which is divided into a plurality of equal parts.

From there, the rice flows down onto each sorting plate 2 and is sorted into paddy, mixed rice of paddy and brown rice, and brown rice while undergoing rocking sorting, and is then discharged from each discharge port 4.

When the amount of grains to be sorted decreases near the end of the sorting operation and the sorting operation cannot be carried out using all the sorting plates 2, the transfer upper side portion 9affi of the box body 9
If removed, the grains in the hopper 6 are directly dropped and supplied to the uppermost sorting plate 2, and it is possible to switch to oscillating sorting using only the uppermost sorting plate 2.

In addition, if the grains are so small that they cannot be sorted by the uppermost sorting plate 2 alone, they remain inside the machine as residual grains, but the grain drop port 8 of the removed transfer upper side part 9ak hopper 6 You can remove the remaining grains by applying it to this container.

As described above, the present invention is based on a box that is integrally attached to the oscillating sorting plate below the grain drop opening that opens above the grain supply side of the oscillating sorting plate and that reciprocates diagonally up and down. The upper side of the iron box and body is designed to be detachable from the lower side of the transfer, and when performing rocking sorting using only the uppermost sorting plate, the upper side of the transfer can be removed to open the grain drop port. Since the grains are supplied directly to the top sorting plate from
Unlike conventional devices that close the grain feeding port with a blocking plate, etc., this device can reliably feed grain only to the uppermost sorting plate, and it also prevents residual grain from being fed. By applying the removed upper transfer portion to the grain dropping port instead of a container, the grains can be easily taken out from the hopper without dropping into the grain feeding port.

Furthermore, according to the present invention, it is possible to narrow the distance between the box and the sorting plate, and as a result, the grain drop port is closer to the sorting plate, so that even if the grains are dropped directly onto the top sorting plate, they will not scatter. At the same time, the position of the hopper can be made as low as possible, and there is a practical effect that a swing sorting machine with a low overall height of the machine body can be provided.
