Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain sorting device for a rice huller.

Problems to be Solved by the Invention A rotary sorting system in which a recess is formed on the inner circumferential surface and a helical receiving trough is provided in the center with a brown rice sorting valve that receives and carries out the brown rice that is sorted by the recess. In the case of a huller that feeds grains into a cylinder and sorts them, a grain layer is formed from the starting end side by the grains fed into the sorting cylinder, and the grains are separated by the recessed part. The brown rice that falls from the raised position is received by a spiral receiving gutter and is sorted from the reduced mixed rice, etc. However, the falling position of the grains depends on the type of grain being supplied, for example, the size of the grain, the small size, etc. This causes an increase or decrease in the reduced mixed rice, and changes in the grain layer thickness in the sorting cylinder due to this increase or decrease tend to have a negative effect on sorting accuracy and efficiency. If it is too long, clogging is likely to occur in the sorting cylinder.

Means for Solving the Problem This invention provides a recess 1 in which grains can fit into the inner circumferential surface.
A helical receiving trough 3 is provided in the center of the sorting tube 2 to receive and carry out the brown rice, and the sorting tube 3 of this trough 3 has a vertically movable upper and lower side that allows the sorting tube to rotate and sort brown rice. A sensing valve 5 which moves up and down depending on the amount of grains supplied at the starting end of the sorting tube 2 and the brown rice sorting valve 4 are provided. The sensor valve 5 is connected to the paddy supply control valve 7, which is to supply paddy to the husking device 6, and the sensing valve 5. In conjunction with the supply relationship, there is a brown rice sorting valve 4 between the sensing valve 5 and the paddy supply control valve 7 and the brown rice sorting valve 4.
The structure of the grain sorting device for a huller is provided with an adjusting device 8 that can change and adjust the relative position of the huller.

Functions and Effects of the Invention In order to sort the scraped rice scraped out by the scraping device 6 with the rotating sorting tube 2, during steady operation, the sorting tube 2 is
When sliding rice is supplied to the starting end to form a certain grain layer, this grain layer is deflected in the rotation direction of the sorting cylinder 2, and some grains fit into one part of the recess and rise. ,
The grains falling from this raised position are received by the brown rice sorting valve 4 and the spiral receiving gutter 3, and are sorted into the brown rice to be transferred through the spiral receiving gutter 3 and the grains remaining in the sorting cylinder 2. , Brown rice sorting valve 4 in the sorting tube 2
By linking the operating position and the position of the sensing valve 5 of the grain layer thickness necessary for sorting in a nearly optimal state, if the grain layer in the sorting tube 2 increases in amount further, the sensing valve 5 detects the grain layer thickness. The brown rice sorting valve 4 rotates downward to increase the amount of paddy to be sorted to the helical receiving trough 3, and at the same time, the paddy supply control valve 7, which should supply paddy to the husking device 6, reduces the amount of paddy to be fed through the control device 8. On the other hand, if the amount of grains in the sorting tube 2 decreases, the sensing valve 5 detects this and rotates the brown rice sorting valve 4 upward to reduce the amount of grain sorted into the helical receiving trough 3. Interlocking adjustments are made to increase the amount of paddy supplied to the hulling device 6, and the grain layer in the sorting tube 2 is restored and stabilized to perform steady work, and during the work, the hulling conditions, for example, When the variety changes, etc., the rising and falling position of the grains within the sorting tube 2 changes,
When increasing the amount of sorting into the helical receiving trough 3, the brown rice sorting valve 4 can be rotated downward, and when paddy is mixed in, it can be changed and adjusted using the adjusting device 8 so that it can be rotated upward. , the sensing valve 5 is linked to this adjustment.

2 and the adjustment weight 39 to rotate downward to increase the amount of sorting to the helical receiving trough 3, and also to adjust the paddy supply that is interlocked through the operating rod 43, shaft 34, operating plate 44, etc. The opening degree of the valve 7 is adjusted to reduce the supply, and if the sensing valve 5 rotates downward in the opposite direction to the above, the brown rice sorting valve 4 rotates upward to reduce the amount of sorted rice to the helical receiving trough 3. At the same time, the opening degree of the paddy supply control valve 7 is adjusted to increase the amount of paddy supplied to maintain the thickness of the grain layer suitable for sorting, so that stable steady operation can be performed.

Also, during the process, the hulling conditions may change, for example, the type of paddy may change, the rotation of the sorting tube 2 may change, or the hulling device 6 may change.
The sorting cylinder 2
If there is a change in the sorting state of the grains within the chamber, the rising and falling position of the grains changes, and if you wish to increase the sorting efficiency, hold the adjustment weight plate 39 and turn the adjustment lever 4.
0 and rotate the operating position of the brown rice sorting valve 4 downward, the amount of rice falling into the helical receiving gutter 3 will increase,
Once the sensing valve 5 is rotated upward, thereby creating a gap between the sensing valve 5 and the grain layer, the sensing valve 5 is moved downward due to the hanging of the adjustment weight plate 39. By rotating, the opening degree of the paddy supply control valve 7 is increased to supply the paddy. Also, if you wish to reduce the sorting processing efficiency, contrary to the above, by operating the adjustment lever 40 in the same manner and rotating the operating position of the brown rice sorting valve 4 upward, the amount of rice falling into the helical receiving gutter 3 will be reduced. Then, the sensing valve 5 is once rotated downward, and as a result, the sensing valve 5 is rotated upward under the pressure of the grain layer, and the opening degree of the paddy supply control valve 7 is reduced to supply rice. It is possible to respond to changes in conditions, obtain a grain layer necessary for sorting, and perform stable work without clogging in the sorting cylinder 2.
