Spiral drum separation type cassava harvester

Abstract

The invention discloses a spiral drum separation type cassava harvester, which belongs to the technical field of agricultural machinery and comprises a transmission device, a cassava and soil separation device, an excavating device, a supporting device and a depth limiting device. The transmission device comprises a transmission shaft; the potato and soil separating device comprises a drum screen and flow guide screen bars, the transmission shaft is arranged on the inner side of the drum screen, the drum screen is of a hollow structure, and the flow guide screen bars are arranged on the inner side of the drum screen and are spirally connected and fixed to the transmission shaft in the axial direction of the conveying shaft; the rotary screen and the transmission shaft both have an inclination angle of 15-25 degrees, and the rotary screen and the flow guide screen bars can be driven by the transmission shaft to rotate together. According to the spiral roller separation type cassava harvester, the designed digging shovel has good soil penetrating performance and soil crushing capacity, a mixture composed of cassava and soil can be dug, the dug mixture can be separated, the spiral roller separation type cassava harvester has the advantages of being simple in structure, convenient to use, good in separation effect, small in cassava root damage and the like, and the spiral roller separation type cassava harvester is suitable for popularization and application. And the potato-soil separation operation efficiency and the overall performance of the cassava harvester can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a cassava harvester, in particular to a helical drum separation type cassava harvester. Background technique [0002] Cassava is also called cassava, cassava, and cassava, sweet potato and potato are known as the world's three major potato species. It is the only species used for economic cultivation in the Euphorbiaceae cassava. It is widely planted all over the world and is an important crop in my country. tropical crops. Cassava is mainly used as feed and starch extraction. Cassava has high nutritional value. Its meal and leaves are high-energy feed ingredients. Cassava roots are rich in starch, and after extraction, they can be used to produce chemical products such as alcohol, fructose, glucose, monosodium glutamate, beer, bread, biscuits, sauces, plastic fibers, plastic films, resins, coatings, and adhesives. And other industries are widely used. As feed, cass...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of the existing cassava harvester, such as the poor performance of digging shovels in the soil and the lack of types of potato-soil separation devices, the effect is poor, and the soil-crushing ability and separation effect are poor when the potato-soil is separated, and the potatoes are damaged and broken. High rate; under complex soil conditions, poor adaptability, low reliability and other issues
