Smooth roll sorting device for potato cleaning and sorting machine

Abstract

The invention provides a smooth roll sorting device for a potato cleaning and sorting machine. The smooth roll sorting device is characterized in that long connecting plates and short connecting plates of each stretching frame are in overlapped connection, forming five rhombuses, and the sequence numbers are I, II, III, IV and V; a motor frame is mounted at the hinge joint of the ends of the long connecting plates of one rhombus III, and a speed reduction motor is connected with a flange of the motor frame and drives smooth roll sorting rollers with two ends supported on the stretching frames to rotate through a transmission device; the two ends of two smooth roll sorting rollers penetrate through round holes in bosses of the short connecting plates of the rhombuses I and the rhombuses V and then stretching-out ends, facing the speed reduction motor, of the two smooth roll sorting rollers are connected with single-row chain wheels, and stretching-out ends of the rest of the smooth roll sorting rollers penetrating through the stretching frames are connected with single-row chain wheels; after penetrating through the single-row chain wheels at the hinge joints of the rhombuses II and the rhombuses III, the stretching-out ends facing the speed reduction motor are connected with the speed reduction motor; and soil scrapers are arranged under the smooth roll sorting rollers. The smooth roll sorting device can conveniently carry out classification on potatoes subjected to preliminary soil removing, the skin breaking rate is low, the sorting rollers are not prone to adhering to soil, and work is stable and reliable.

Description

technical field [0001] The invention provides a smooth roller sorting device of a potato cleaning machine, which is mainly used for grading potatoes after the potatoes have been harvested and soil and other impurities adhering to the surface of the potatoes have been preliminarily removed. Background technique [0002] China is one of the countries with the largest potato planting area in the world. At the same time, China's potato consumption is growing at an average annual rate of 8%, and it is also one of the fastest growing countries in the world. In recent years, the sowing and harvesting of the domestic potato production industry has been basically mechanized, but the surface of the harvested potatoes is often still adhered to a layer of soil, and some potato seedlings, weeds and soil clods are mixed between the potato pieces. Therefore, Shandong Xicheng Agricultural Machinery Technology Co., Ltd. applied for the national invention patent "Potato Cleaning Conveyor Clea...
