Straw pulverizer absorbing crushed straw

Abstract

The invention discloses a straw pulverizer absorbing crushed straws. The straw pulverizer comprises a machine body. The upper part of the machine body is provided with a feed port. Two rolling wheels which rotate in reverse directions are arranged below the feed port. A belt pulley of a drive motor on the outer side of the machine body is connected with a belt pulley on a smashing roll rotating shaft in the machine body through a belt. A smashing roll is below the rolling wheels. A long plate which is in an inclined manner and connected with a discharge port is arranged below the smashing roll. One side of the machine body, above the discharge port, protrudes a housing, and is provided with a fan. The side surface of the machine body, protruding the housing, is connected with a material absorbing cover through a pipe. The fan and a pipe mouth which is connected with the protruded housing of the machine body are separated by a separating plate. The lower part of the fan and a smashing cavity of the smashing roll are separated by an inclined plate. The straw pulverizer absorbing crushed straws can roll extra air out of the straws in advance, so as to improve smashing efficiency. The straw pulverizer absorbing crushed straw can absorb fallen crushed straws into the discharge port to discharge the crushed straws, so as to reduce troubles of cleaning.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a straw pulverizer for absorbing debris. 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, and straw is also a roughage. It is characterized by high crude fiber content and lignin. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. Chinese farmers have a long history of using crop stalks, but due to the low level of agricultu...

Problems solved by technology

[0003] The traditional straw grinder cannot squeeze out the air in the straw before crushing, so that the crushed straw takes up too much space, and after the straw is crushed, there will be a lot of crushed debris on the ground and on the machine, which is relatively difficult to clean. Trouble, not conducive to reducing the burden on agricultural workers and improving work efficiency
