Sorting device with protection sleeves of potato cleaner

Abstract

The invention provides a sorting device with protection sleeves of a potato cleaner. The sorting device is characterized in that long connecting sheets and short connecting sheets of telescopic frames are overlapped and connected to form five rhombuses, and the sequence numbers of the rhombuses are I, II, III, IV and V; a motor rack is mounted at the hinged position of the ends of the long connecting sheets of the rhombus III; a gear motor is connected with a flange of the motor rack; sorting rollers with the two ends borne on the telescopic frames are driven by a transmission device to rotate; the outer circle of a spring wire of each spring is sleeved with one corresponding protection sleeve; after the two ends of one sorting roller I and the two ends of one sorting roller II penetrate round holes in bosses of the short connecting sheets of the rhombus I and the rhombus V, the stretching ends, in the direction of the gear motor, of the sorting roller I and the sorting roller II are connected with single-row chain wheels; and the stretching ends, penetrating the telescopic frames, of the rest of the sorting rollers are all connected with single-row chain wheels, and after penetrating single-row chain wheels at the hinged position of the rhombus II and the rhombus III, the stretching ends, facing the gear motor, of the rest of the sorting rollers are connected with the gear motor. The sorting device can classify thoroughly-cleaned potatoes conveniently, and is low in potato damage rate, even and thorough in sorting and wide in application range.

Description

technical field [0001] The invention provides a sorting device with a protective cover for a potato cleaning machine, which is mainly used for grading the potatoes after the potatoes are harvested and the soil and other impurities adhering to the surface of the potatoes have been 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 often sticks to a layer of soil, which is also mixed with some potato seedlings and weeds. Therefore, Shandong Xicheng Agricultural Machinery Technology Co., Ltd. applied for the national invention patent "Potato Cleaning Conveyor Cleaning Device", the application number i...
