Description

[Detailed description of the invention] Field of industrial application This invention relates to a rotary sorting machine that supplies grains such as rice and wheat and other granules into a sorting tube, allows small-diameter grains to leak through the sorting holes in the sorting tube, and sorts the grains into large, regular grains and small-diameter waste grains, and makes it easy to change the sorting rate.

Conventional technology In a rotary sorting machine, in order to prevent particles from clogging the sorting holes provided in the sorting tube, a clogging prevention tool that slides on the outer circumferential surface of the sorting tube is installed. A part of the anti-clogging tool is interlocked with a handle provided to protrude outside the machine casing, and the anti-clogging tool is separated from the sorting tube by operating the handle, causing clogging in a part of the sorting tube. A structure is known in which the sorting rate is changed by making the sorting rate worse.

Problems to be Solved by the Invention The above-mentioned structure requires a mechanism for interlocking and connecting the handle and a part of the clogging prevention device, and is complicated in structure.

Means for Solving the Problems For this reason, the present invention utilizes an inspection lid provided on the machine casing and a replacement opening/closing lid for the sorting tube, and is configured as follows.

That is, the anti-clogging tool 3 that slides on the outer circumferential surface of the sorting tube 2 that is shaft-mounted in the inner cavity of the machine casing 1 and acts to remove particles clogging the sorting hole provided in the sorting tube 2 is attached to the sorting tube 2. The divided anti-clogging tool 3 is attached to the inner surface of a lid 4 that opens the inner cavity of the machine casing 1, and the sorting rate can be changed by opening and closing the lid 4. Configured.

Function: When the lid 4 provided on the machine casing 1 is opened to the inner cavity, the clogging preventive device 3 attached to the inner surface of the lid 4 is separated from the sorting tube 2, and the part of the sorting tube 2 is removed. If the section becomes clogged, the sorting rate can be changed.

Effects of the invention: Since the sorting rate can be changed by opening and closing the lid 4 provided on the machine housing 1, there is no need for a handle to change the sorting rate in the conventional structure, and the structure is simple and can be manufactured at low cost. .

In addition, the clogging prevention tool 3 attached to the lid body 4 can be replaced while being taken out from the machine casing 1, making the work easier.

Embodiment Next, an embodiment of this invention will be explained with reference to the drawings.
In this embodiment, a sorting tube 2 having a hexagonal or circular cross section is mounted on an axis in the inner cavity of a machine casing 1, and a large number of holes are provided on the circumferential surface of the sorting tube. A deceleration motor 5 is connected to one end of this sorting cylinder to drive and rotate it. A supply port 6 for supplying granules into the sorting tube 2 is provided on the deceleration motor 5 side of the machine casing 1, and a discharge port 7 for taking out the sorted particles sorted by the sorting tube 2 is provided on the other side.
8 will be provided. A grain lifting tube 9 is provided on the side of the discharge ports 7 and 8, so that the grains accumulated at the lower part of the inner surface of the sorting tube 2 are lifted upward and taken out from the discharge ports 7 and 8. Reference numeral 10 denotes a switching valve that changes the direction of granule discharge between the upper discharge port 7 and the lower discharge port 8.

At the bottom of the sorting tube 2 of the machine casing 1, there is a waste particle discharge port 11,1 for discharging the waste particles leaking from the sorting tube 2 to the outside of the machine.
2 and 13, and an opening 14 slightly wider than the sorting tube 2 is provided at the top of the sorting tube 2 in order to take out the sorting tube 2 outside the machine and replace it with another sorting tube. A lid 15 is provided. Also, machine casing 1
An inspection window 16 for checking the operating condition of the sorting cylinder 2 is provided near the opening 14 of the inspection lid 1.
7, 18 to open and close freely. This inspection lid 17,1
8 has an upper part pivoted 19 to the machine casing 1, and a lower part attached to the machine casing 1 with a fastener 20, so that the inner cavity of the machine casing 1 can be opened and closed. 21 and 25 are legs that support the machine casing 1 on the ground.

The anti-clogging tool 3 is a plate made of rubber material, and is divided into three parts 3, 3', and 3'' in the axial direction of the sorting tube 2.
Since the sliding contact position is changed up and down on the circumferential surface of the clogging prevention tool 3 on the fixed side, the ends are partially overlapped.
3' are brackets 22 and 23 fixed to the inside of the machine casing.
A part of the clogging prevention tool 3' is fixed to a bracket 24 fixed to the inner surface of the inspection lid 17.

The granules supplied from the supply port 6 enter the rotating sorting cylinder 2 and are sent in the axial direction by the inclination of the sorting cylinder 2, which is slightly inclined from the supply port 6 toward the discharge ports 7 and 8. The waste grains fall downward from the sorting hole on the circumference while the waste grains are discharged from the machine casing 1 through the waste grain discharge ports 11, 12, and 13. Depending on the position 10, the liquid is discharged out of the machine casing 1 from the upper discharge port 7 or the lower discharge port 8.

The granules sorted by the sorting cylinder 2 tend to have fine waste particles leaking out near the supply port 6 and near-sized waste particles leaking out as they approach the discharge ports 7 and 8. If waste grains similar to those of
By opening the inspection lid 17, the anti-clogging tool 3' attached to the inner surface of the inspection lid 17 is removed from the sorting tube 2.
This is done by clogging the sorting tube 2 away from the circumferential surface of the tube.

In the embodiment, the clogging prevention device 3 is divided into three parts, but it may be divided into two or four parts as appropriate, or all the clogging prevention devices 3 may be attached to the opening/closing lid 15. . Furthermore, this invention can be implemented not only when the sorting tube 2 is mounted on an axis approximately horizontally, but also when it is tilted or vertically mounted.
