Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain sorting device for sorting mixed rice of paddy and brown rice using a rotating sorting cylinder having a large number of pot holes on its inner circumferential surface. More specifically, the present invention relates to a cleaning device for the pot hole of this rotary sorting cylinder. [Prior Art] There is a grain sorting machine that sorts a mixed rice of paddy and brown rice by rotating a rotary sorting tube, which has a large number of pot holes on its inner circumferential surface, around a horizontal axis. Since the pot hole of this rotating sorting cylinder is clogged with dust, there is a cleaning device that removes the dust inside the pot hole using a rotating brush roll. [The same problem that the invention seeks to solve] However, in this conventional device, a special brush roll for cleaning the pot holes in the rotating sorting tube is provided, which increases the cost. In addition, there was a problem in that grains remained in the grain receiving trough installed in the rotary sorting cylinder after the work was completed. Therefore, this invention provides a grain receiving gutter in a single-rotation sorting cylinder with a brush transfer helix for transporting grains, so that the grains in the grain receiving gutter are removed by this brush transfer helix so that no grains remain. By repositioning this brush transfer helix near the pot hole of the rotary sorting tube and cleaning the pot hole of the rotary sorting tube, it is possible to improve the efficiency of conventional equipment.
This is an attempt to solve the problems all at once. [Means for Solving the Problem] The technical means of the present invention for solving such technical problems is a rotary sorting cylinder 11 that has a large number of potholes formed on its inner peripheral surface and rotates around a horizontal axis. A grain receiving gutter 16 is installed inside the rotary sorting cylinder 11 to receive the grains pumped up through the pot hole, and a brush transfer helix 24 is mounted in the grain receiving gutter 16. The grain is characterized in that the helix 24 is configured to be freely changeable between a state in which the grains are transported at the bottom of the grain receiving trough 16 and a state in which the pot hole near the inner peripheral surface of the rotary sorting tube 11 is cleaned. This is a configuration of a transport cleaning device for a grain sorting device. [Operations and Effects of the Invention] During sorting work using the rotary sorting tube 11, the brush transfer helix 24 is positioned within the grain receiver @16 of the rotary sorting tube 11,
The brown rice that has been pumped up high through the pot hole of the rotating sorting tube 11 falls into the upper grain receiving trough 16 and is sorted, and the unhulled rice and brown rice that have been pumped up low fall into the rotating sorting tube 11 and are sorted. The grains that have fallen into the grain receiver 4i1i16 are transported smoothly by the brush transfer helix 24 with little or no residue. After the sorting work is completed, the brush transfer helix 24 is moved to a position where it contacts the pot hole of the rotary sorting cylinder 11 and rotates.
The brush transfer helix 24 can also be used to clean the pot holes, increasing sorting efficiency. [Example] Hereinafter, an example of the present invention shown in the drawings will be described.
