Description

Cassava stem cutting and returning all-in-one machine

Technical Field

The invention belongs to the field of agricultural machinery, relates to a stalk crushing and returning device, and particularly relates to an integrated machine for directly cutting cassava stalks in a field, crushing the cassava stalks, mixing the crushed cassava stalks with a bacterial liquid and a matrix, and then spreading the crushed cassava stalks to return to the field.

Background

Cassava (Manihotesculenta) is one of three potato crops in the world, is widely cultivated in tropical and subtropical regions, and is also an important raw material in the fields of food, chemical industry, medicine, biological energy and the like. The worldwide cassava planting area in 2019 is 2436.21 ten thousand hectares. The cassava stalks are byproducts in the cassava production process, and the yield is 70-80% of the cassava root tubers. The large-scale cassava planting inevitably generates a large amount of cassava stalks, and except that about 10 percent of the cassava stalks are used for seed preservation, other stalks are treated in a returning mode.

At present, the cassava stem returning treatment method mainly comprises 2 methods: (1) the cassava stalks are directly piled up and burned on the ridges at the head of the field, the method needs to move the cassava stalks out of the cassava field and pile the cassava stalks, a large amount of manpower is consumed, and under the situation that the labor cost is increased day by day, the production cost of the cassava is greatly increased by the operation mode. In addition, the incineration not only pollutes the environment, but also wastes the potential utilization value of the cassava stalks. (2) Directly crushing and returning to the field. Although the method can solve the problem of environmental pollution caused by burning the cassava straws, the decomposition speed of the decomposed cassava straws is extremely low, the cassava straws cannot be completely decomposed even in one cultivation period, the nutrients are difficult to return to the field again, and meanwhile, the cassava straws which are not decomposed can also influence the subsequent mechanical operation.

Researches show that proper microbial agents are added into crushed cassava stems, cassava residues (waste in the cassava processing process) are used as microbial agent propagation substrates, the decomposition speed of the cassava stems can be accelerated, and the decomposition period is only half of the natural decomposition period. The microbial inoculant is used as an auxiliary agent in the process of crushing and returning cassava stalks into fields, so that the problem of low decomposition speed of directly crushing the cassava stalks and naturally decomposing the cassava stalks into fields, the problem of environmental pollution caused by incineration of the cassava stalks can be solved, the utilization rate of the cassava stalks can be greatly improved, and the popularization, the popularization and the application of the crushing and returning the cassava stalks into fields are well promoted. The existing cassava harvester integrates cassava harvesting and stalk collection into a whole, so that the operation efficiency is effectively improved, but the stalk returning process only crushes the cassava stalks and then directly returns the crushed cassava stalks to the field, so that the crushing effect is poor, the crushing degree is small, the subsequent decomposition period is influenced, the stalks are not scattered and returned to the field, the nutrients are difficult to return to the field in a distributed mode, and the actual requirement of returning the crop stalks to the field cannot be met.
