Shifting roller type cassava digging and harvesting machine

Abstract

The invention discloses a shifting roller type cassava digging and harvesting machine. The shifting roller type cassava digging and harvesting machine comprises a rack, the upper part of the left endof the rack is connected with a towing vehicle through a trifilar suspension mechanism, a land wheel is arranged at the bottom part of the right end of the rack, the shifting roller type cassava digging and harvesting machine further comprises a plurality of digging shovels, a shovel plate, a plurality of lifting rods and at least two shifting rollers, the shifting rollers are installed on the rack, the shifting roller comprises a rotating shaft and a plurality of cassava soil separation rods distributed on the rotating shaft, the cassava soil separation rods on the adjacent shifting rollers are mutually staggered, the shovel plate is located at the bottom part of the left end of the rack, one end of the lifting rod is welded with the right side of the shovel plate, the other end of the lifting rod is located at the upper part of the leftmost shifting roller, the towing vehicle tows the rack to move forwards, a cassava block dug out by the digging shovel and a soil layer wrapped on theouter part of the cassava block are sequentially processed through the shifting rollers, and the soil and the cassava are separated. Due to the adoption of the above structure form, the oil layer andthe cassava are separated, so that the rate of the clear cassava is increased, and the subsequent operation of manually picking up the cassava is facilitated.

Description

technical field [0001] The invention relates to cassava digging and harvesting equipment, in particular to a cassava digging and harvesting machine. Background technique [0002] Cassava is the world's food crop. Cassava starch is an important chemical and food industry raw material in my country, and it is also a non-food energy (fuel ethanol) crop. The planting area in my country is 7-8 million mu, and it is planted in all provinces in South China. Because cassava does not have high requirements on soil and management technology, it is the main crop for farmers in old revolutionary areas in hot areas, ethnic minority areas, border areas and mountainous areas. The rotation of cassava and sugarcane is the main farming mode in my country's hot areas. [0003] Cassava harvesting mainly refers to the harvesting of underground cassava roots (i.e. potato pieces), and the harvesting link is a key link in the whole mechanized mode of cassava production. my country's cassava mechan...

AI Technical Summary

Problems solved by technology

This type of equipment is characterized by a low clear potato rate (the probability that the cassava tubers can be clearly seen on the surface of the cassava ground), and at the same time, the labor cost required for uprooting is relatively high

2. The vibrating chain row type, which is improved from the potato harvester, is a vibrating chain row type cassava harvester, which has a relatively high harvest rate of clear potatoes, but the vibrating chain row has poor adaptability to work in the southern hot zone soil conditions, and the chain row is easily damaged. , the problem that new equipment will be damaged after working less than 30 mu frequently appears, and the poor reliability has seriously affected the practicability of the equipment

Due to the lack of mature and available cassava harvesting equipment, the development of the cassava industry has been severely restricted
