Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product processing, in particular to a shelling machine for agricultural product processing. Background Art

[0002] The grains of rice are called rice grains. After the husks are removed from the rice grains, they are called brown rice. The bran layer of brown rice can be removed to obtain rice. Therefore, rice husking equipment is needed to complete the husking operation.

[0003] After searching, it is found that a rice shelling device for deep processing of agricultural products is disclosed in a Chinese patent document [Application No.: CN202222660513.8]. This rice shelling device for deep processing of agricultural products includes a processing box, a vibrating screen is installed inside the processing box, and a limit assembly is installed on one side of the vibrating screen; the limit assembly includes an inclined limit support plate installed on one side of the vibrating screen, and the bottom end of the inclined limit support plate is connected to a linkage rod, and a linkage cylinder for extension and retraction is installed at the bottom end of the linkage rod.

[0004] The device disclosed in the patent can separate the fallen brown rice and small particles. However, after the device has completed screening of part of the brown rice and discharges the brown rice, it is necessary to drive the inclined limit support plate to descend through the coordinated use of the linkage cylinder and the linkage rod so that the brown rice can be discharged smoothly. At this time, since it is impossible to limit the continuously falling brown rice, when the staff unloads the brown rice on the vibrating screen, it is necessary to stop the rubber roller from shelling the subsequent rice to ensure the screening effect. This method will directly affect the overall rice shelling process and the efficiency of the shelling operation. In addition, the position of the vibrating screen is relatively fixed, and it is inconvenient for the staff to disassemble and clean it. If things go on like this, the screening efficiency of the vibrating screen will be affected. Utility Model Content

In this process, the screened small particles are discharged through the discharge mechanism 21. Finally, the staff starts the servo motor 151 and performs reverse operation to drive the lifting plate 17 to lift and seal the discharge port 16.
