Description

[Detailed description of the invention] This invention relates to a movement guide device for a grain receiving gutter that receives and guides the transfer of sorted grains falling from an outlet of a sorting board in a swing sorting machine. The purpose of this is to ensure that the process is carried out smoothly.

For this reason, the following technical measures were taken.

That is, a pair of upper and lower guide plates 5 and 6 forming a sliding guide groove 4 are provided on the side frame 3 located on the side of the sorted grain discharge port 2 of the oscillating sorting board 10.
A grain receiving trough 7 for receiving and transporting the sorted grains falling from the sorted grain outlet 2 is slidably interposed in the sliding guide grooves 4 of the guide plates 5 and 6. At the same time, the edge 5a of the upper guide plate 5 is formed to protrude longer toward the inside of the grain receiving trough 7 than the edge 6a of the lower guide plate 6.

In the illustrated example, 8 is a well-known swing sorting machine, which is located above the frame 9, and whose entire board surface forms a rough, uneven surface, has a supply port at the - side end, and a sorting machine on the other side. It is formed by stacking sorting boards 1 having grain discharge ports 2 in multiple stages, and is configured to be able to swing in the direction of arrow A by a swinging mechanism 11 in an inclined state where the supply port side is on the upper side and the opposite side is on the lower side. The grains on the sorting board 1 are sorted by specific gravity into each layer of paddy, mixed rice, and brown rice.

Reference numeral 12 denotes a partition plate, which is placed on the side of the sorted grain outlet 2 of the sorting board 1 and is moved along the longitudinal direction of the outlet 2 (indicated by the arrow) on a side frame 3 that swings in the same direction as the sorting board 1. It is composed of a first partition plate 12a that can be provided and partitions the ground layer and the mixed rice layer, and a second partition plate 12b that partitions the mixed rice layer and the brown rice layer.

The guide plates 5 and 6 are arranged on the left and right sides of the side frame 3, and the sorting plates 1
It is obliquely installed along the longitudinal direction of the sorted powder outlet 2.

In the illustrated example, the grain receiving trough 7 is a mixed rice receiving trough, and faces downward from the sorted powder outlet 2 and the second partition plate 12b.
.
It is configured to be locked by a locking portion 13 provided on the bottom surface 12c of the partition plate 12b, and to move following the second partition plate 12b.

In the guide plates 5 and 6, the edge 5a of the upper guide plate 5 is longer than the edge 6a of the lower guide plate 6 so as to protrude inwardly into the mixed rice receiving trough 1.

14 is a paddy receiving trough, 15 is a paddy discharge port, 16 is a mixed rice flow down trough 1
7 is an exit, 18 is a brown rice transfer rack, and 19 is a brown rice outlet.

Incidentally, the grain receiving trough T is not limited to a mixed rice receiving trough, but may be a paddy receiving trough or a brown rice receiving trough, and therefore, the structure is not limited to that of this example. .

In the upper configuration, the grains fed onto the sorting board 1 are
Under the shaking action, the grains are sorted from the lower side of the inclination to the upper side in order into each layer of paddy, mixed rice, and brown rice, and these sorted grains fall and are discharged from the outlet 2.

At this time, when the first and second partition plates 12a and 12b are moved and adjusted in the direction of the arrow to match the distribution layer of each sorted grain, the paddy is discharged from the paddy discharge port 15 while flowing down the paddy receiving trough 14. The mixed rice flows down on the bottom surface 12c of the second partition plate 12b and the mixed rice receiving trough 7, and is discharged from the outlet 16 of the mixed rice flow down trough 17, and the brown rice is discharged from the machine through the rack 18g.

Next, if the distribution layer of mixed rice and brown rice changes and, for example, the second partition plate 12b is moved and adjusted to the upper side of the slope of the sorting board 1, the mixed rice receiving trough T follows the movement of this partition plate 12b. Move to opening.

At this time, a space H is created between the ends of the guide plates 5 and 6 and the end of the mixed rice receiving trough 1.

(See Figure 2) In this state, the mixed rice flows down on the mixed rice receiving gutter T and falls from the end of the receiving gutter 1 through the space H into the mixed rice flow lower gutter 1. Contaminants such as mixed rice and straw waste that fall from the T end or fall directly from the sorting grain outlet 2 without passing through the mixed rice receiving trough T are used for the swinging action of the mixed rice receiving trough 7 itself and the sorting board 1. Under the influence of the oscillating motion, the scattering is further promoted and tends to easily enter the sliding guide groove 4 of the guide plate 5°6 between the spaces H, but according to the present invention, as described above, Since the edge 5a of the upper guide plate 5 is formed to protrude longer inward than the edge 6a of the lower guide plate 6, it is difficult for the mixed rice and foreign matter to enter and migrate into the sliding contact guide groove 4. It is possible to prevent mixed rice and the like from easily entering the sliding guide groove 4 by being restricted (obstructed) by the edge 5a of the plate 5.

As mentioned above, this invention includes a grain receiving gutter that is slidably interposed in a sliding guide groove formed by a pair of upper and lower guide plates, and an edge of the lower guide plate that is the edge of the upper guide plate. Since it is formed to protrude longer inward from the grain receiving trough than the edge,
When sorted grains, etc. fall from the end of the grain receiving trough, even if they try to move into the sliding guide groove, their movement is restricted by the edge of the upper guide plate and they do not enter the sliding guide groove. As a result, the movement of the grain receiving trough within the sliding guide groove is carried out smoothly without being hindered by the sorted grains etc. that have entered.
