Efficient Spiral Screening Machine

Abstract

The invention patent is a high-efficiency spiral screening machine, which belongs to the technical field of agricultural machinery. The patent of the present invention is a new technology that uses the spiral material guide plate between the built-in feeder and the outer spiral screen to perform centrifugal screening, separation and removal of impurities when lifting materials. Through the gradual advancement of the spiral material guide plate, the material is lifted Gravity slides down and falls onto the triangular crusher for inertial crushing. The transportation of materials in the screw screening machine is completely a sliding movement, achieving a mechanical equipment that integrates lifting, screening, crushing, separation, and transportation. Has to complete the harvest of different crops. This type of screening machine not only adds a new mechanical transmission mode in the field of transportation, but also can be used in the design of other crop harvesting machines, which greatly surpasses the functions of traditional crop harvesting machines and breaks the existing design of crop harvesting machines idea.

Description

Technical field: [0001] The invention relates to a high-efficiency spiral screening machine, which belongs to the technical field of agricultural machinery. Background technique: [0002] All kinds of crops planted in my country include food crops and economic crops. From the perspective of planting space, more and more underground crops are paid more attention, such as oily beans, potatoes, sweet potatoes, yams, taro, Jerusalem artichoke, garlic, onions, Chinese herbal medicines, etc., can be used as food for human consumption, feed for animals, and can also be used for starch, wine making, and medicinal purposes. They are widely used in food and non-food industries, and their development prospects are broad. Especially underground tuber crops, such as oily beans, peanuts, etc., have high yields and store rich nutrients. [0003] At present, the harvesting method of tuber crops in most areas in China is still mainly manual harvesting, some areas use digging plows, and a few...

AI Technical Summary

Problems solved by technology

[0005] At present, there are structural contradictions in harvesting machinery in the production process of tuber crops in my country, and the effective supply is insufficient; there are many small machinery and tools, and large and medium-sized agricultural machinery and tools cannot keep up with the development needs; there are not many types and specifications of machinery, and the quality and performance are unstable. Insufficient research and development efforts; there are weak or even blank links in mechanical operations, which do not meet the needs of strategic adjustment of agricultural and rural economic structures; there are serious problems such as aging machinery and tools, low technical level, and insufficient investment in renewal.

Harvesting machinery cannot meet the actual needs of tuber crop production, which directly affects farmers' enthusiasm for planting and purchasing machinery
