Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a rotary sorting tube that has a large number of pot holes on its inner circumferential surface, and is a rotary sorting tube type that sorts mixed grains of paddy, brown rice, etc. The present invention relates to improvements to grain sorting machines.

[Prior art] In the case of a rotary sorting tube type sorting device, the rotary sorting tube is replaced depending on the size of grains to be sorted, or it is removed from the machine when cleaning the rotary sorting tube. There is a need. However, the area around the rotary sorting tube is covered with a sorting case to prevent dust and danger, and inside the rotary sorting tube there is a grain receiving trough for collecting sorted grains and a grain conveying device. Because it is supported internally, it is difficult to remove and remove the rotating sorting tube.
Installation is extremely difficult. As a conventional technique for attaching and detaching this rotary sorting tube,
There is a publication No. 60-222181.

[Problems to be Solved by the Invention] In this prior art, when the rotating sorting tube is removed from the sorting case, the rotating sorting tube, the grain receiving trough and the grain conveying means installed in the rotating sorting tube are also removed together. Since it is a removable structure, the weight of the components to be removed from the sorting case is heavy, and the grain receiving trough and grain conveyance means are still inside the rotary sorting tube when they are removed, so it is necessary to clean the rotary sorting tube. At times, there was a problem that the grain receiving trough and the conveying means were an obstacle.

Therefore, when removing the rotary sorting tube from the sorting case, this invention saves the number of these components by applying a special arrangement between the rotary sorting tube, the grain receiving gutter that receives the sorted grains, and the sorting case. However, it is easy to attach and detach the opening/closing side plate of the sorting case and the grain receiving gutter, and the grain receiving gutter and one end of the grain conveying means installed in the rotary sorting tube remain connected to the sorting case. By removing the rotary sorting tube in this state, the rotary sorting tube can be easily attached and detached, thereby solving the drawbacks of the prior art.

[Means for Solving the Problems] The technical means of the present invention for solving the above-mentioned technical problems is to install a rotary sorting tube 11 having a large number of pot holes on its inner circumferential surface inside a sorting case 10 with a horizontal axis. The front end, which is one end side of the grain gutter 16, which is supported rotatably around the rotating sorting tube 11 and is located inside the rotating sorting tube 11 and receives the grains pumped up by the rotating sorting tube 11, is connected to the front end of the sorting case 10. Connected to the side wall 31, this grain gutter 1
The grain transfer lance 15 in 6 is configured to transmit power only from the front side of the machine body and not from the rear side of the machine body, and the front end of this grain gutter 16 is connected to the front side wall 31 of the sorting case 10. In a grain sorting machine in which the rotary sorting cylinder 11 can be pulled out from the front side to the rear side while the rotary sorting tube 11 is being held, the support plate 34 provided at the rear end, which is the other end side of the grain gutter 16, is attached to the sorting case 10. The rear end side of the grain gutter 16 is removably fitted and supported at the opening 32a provided in the rear opening/closing side wall 32 of the sorting case 10. The grain gutter support device of the grain sorting machine is characterized in that when the support plate 34 is fitted, both the opening/closing side wall 32 and the rear side of the support plate 34 face the rear space of the sorting case 10. .
