Description

[Detailed explanation of the invention] (a) Industrial application field This invention has a large number of pot holes formed on the inner peripheral surface, and the discharge side of the pot is supported by a pair of drive wheels so that it can rotate laterally. This is a pot-hole type sorting machine in which a brown rice receiving trough is inserted into a sorting barrel that is mounted on the machine body, and the sorting barrel can be easily removed from the machine and inserted into the machine. This invention relates to a sorting barrel removal device that can be used very easily.

(b) Conventional technology As mentioned above, a brown rice container is installed in a sorting cylinder that has a number of pot holes formed in its inner circumferential surface and is rotatably suspended horizontally with its discharge side and supply side supported by drive wheels. The applicant created a pot-hole type sorting machine with a gutter housed inside the body, and the sorting barrel could be inserted and removed in the direction of the rotation axis, and the applicant first filed Japanese Patent Application No. 60-27351. The application was filed as a.

However, the configuration of this patent application filed as No. 60-27351 is that two guide rails for inserting and removing the sorting cylinder are installed horizontally below the sorting cylinder, and the guide rails for the sorting cylinder are installed in parallel. Since the cylinder is horizontally suspended from the discharge side to the supply side, the outlet opened on the side where the sorting cylinder is inserted and removed is just enough to insert and remove the sorting cylinder, and there is not enough room to remove it. Insertion and removal cannot be performed smoothly. Furthermore, when inserting the sorting cylinder, it is difficult for the back side to rest on the drive wheel.

(c) Problems that the invention seeks to solve The invention created and filed earlier by the applicant has the above-mentioned problems, and it is difficult to remove the sorting barrel from the machine and insert it into the machine. Since this cannot be done smoothly and easily, the present invention has been devised with the aim of improving this and providing a device that has a simple structure and can be inserted and removed very easily.

(d) Means for solving the problems Therefore, in order to achieve the above-mentioned purpose, the present invention inserts a brown rice receiving trough, forms a large number of pot holes on the inner circumferential surface, and connects the drain side and the supply side. A pot-hole type sorting machine that houses a sorting barrel supported by a pair of drive wheels and rotatably mounted horizontally within the machine body, and the sorting barrel is moved in the direction of the rotational axis of the sorting barrel. In a device configured to be freely inserted and removed, a guide rail for receiving and removing the sorting cylinder is installed horizontally below the sorting cylinder parallel to the rotational axis direction, and the guide rail has a reverse cross-sectional shape. In addition, the sorting cylinder is designed to be tilted and lowered at the side where the sorting cylinder is inserted and removed.

(E) Function When inserting or removing the sorting cylinder, the outlet of the side where the sorting cylinder is inserted or removed is opened first, but the guide rail is installed at an angle with the side where the sorting cylinder is inserted or removed lowered. Because of this, the outlet can be made larger and there can be a large margin between it and the sorting cylinder. To extract the cylinder, lift the front side of the sorting cylinder and float it above the drive wheel on the insertion/extraction side, then the back side will come off the drive wheel on the back side and move to the opposite direction. It is stably received by the rail and extracted while sliding on the guide rail. When most of the sorting cylinder is taken out of the machine, the sorting cylinder can be taken out of the machine by lifting the rear part of the sorting cylinder and passing it over the front driving wheel. Also, when inserting the sorting cylinder into the machine, lift the rear part of the sorting cylinder, pass the drive wheel on the front side from the take-out port, and insert it with the guide rail. It is inserted by swinging on the rail.
At this time, since the ejection port is formed large, it is possible to insert the sorting cylinder with the front end lowered, and the inclination of the guide rail causes it to gradually float up and the rear end of the sorting cylinder is lowered. When the front side of the sorting cylinder goes over the front drive wheel, the back side will rest on the drive wheel and the front side will also rest on the drive wheel. It will be stored on board the aircraft.

Due to the lifting action of the pot hole 7, the brown rice falls in a parabola into the brown rice receiving trough 9, is sent forward by the screw conveyor 12, and is led out from the brown rice trough 31 to the wind sorting section B. The paddy that has not passed through the gate valve 14 and reached the brown rice receiving gutter 9 falls into the transfer gutter 10 and is transferred to the rear, where it is again subjected to the sorting action by the pot hole 7, and the remaining paddy from the brown rice is removed. The rice is pumped up by the buckets 28 evenly distributed at the front of the sorting barrel 8, falls into the reintroduction gutter 4, and is returned to the paddy tank 1 as described above, thereby separating the mixed rice into brown rice and paddy.

When cleaning and inspecting the sorting cylinder 8 after completing this work, remove the mounting bolts 18 and fixing bolts 19 that attach the cover plate 17, and the cover plate 17 and flange 26 will be attached to the machine body. is removed, and the outlet 16 becomes open as shown in FIG.

Therefore, when the front side of the sorting cylinder 8 is slightly lifted and lifted above the driving wheels 6, 6 as shown by the imaginary line B in FIG. 5, the collar portion 20 is received by the upper edges 22a, 22a of the guide rail 22, and is pulled out while sliding on the guide rail 22 as shown by the imaginary line C. When most of the sorting cylinder 8 has been pulled out of the machine and is in the state shown in the virtual line 2, the sorting cylinder 8 can be moved out of the machine by lifting the rear part and passing the drive wheels 6, 6 on the front side. It can be completely removed outside.

When inserting the sorting cylinder 8 into the machine, lift up the rear part of the sorting cylinder 8 and move the drive wheels 6, 6 toward the front from the outlet 16 as shown by the imaginary line E in FIG. over the upper edges 22a, 22 of the guide rail 22, and move the flange 20 on the back side to the imaginary line.
