Novel agricultural compost mechanical straw smashing device

Abstract

The invention relates to a novel agricultural compost mechanical straw smashing device which comprises a drying tank, a cutting tank, a smashing tank and a motor chamber. The drying tank is fixedly connected to the top of the cutting tank, the cutting tank is fixedly connected to the top of the smashing tank, the motor chamber is arranged at the left end of the smashing tank, support rods are fixedly connected with the bottom of the smashing tank, bases are fixedly connected with the bottoms of the support rods, a feed bin is arranged on the top of the drying tank, a humidity sensor is furtherarranged inside the drying tank, a turnover plate is arranged in the cutting tank, a cutting plate is arranged above the turnover plate, cutter knives are fixedly connected with the bottom of the cutting plate, hydraulic telescopic rods are fixedly connected with the top of the cutting plate, and hydraulic cylinders are arranged on the tops of the hydraulic telescopic rods and are fixedly connected to the top of the inner wall of the cutting tank. The novel agricultural compost mechanical straw smashing device has the advantages that the novel agricultural compost mechanical straw smashing device with the integral structure has diversified drying, cut-off, smashing and dust removal functions, smashing treatment on straw can be facilitated, the smashing efficiency can be improved, and goodsmashing effects can be realized.

Description

technical field [0001] The invention relates to a novel mechanical straw crushing device for agricultural composting, which belongs to the field of agricultural machinery. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after the seeds are harvested. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource. Straw is also a roughage. The crude fiber content is high (30%-40%), and contains lignin, etc. Although lignocellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. The use of straw has a long history, but due to the low level of agricultural production a...

Problems solved by technology

Straw returning to the field includes composting, retting, and direct returning. With the development of society, the level of agricultural production has also increased rapidly. In the process of agricultural composting, straw should be used as compost material. In the process of making straw into fertilizer, it needs to be crushed. In the existing technology, most straws for agricultural composting are cut and crushed manually instead of mechanized operation, which not only consumes a long time, but also has low working efficiency. At the same time, the humidity of the straw is high, and it is easy to cause uneven treatment if it is directly cut and crushed without treatment.
