Square bundle straw crusher capable of achieving blending cutting and beating secondary crushing

Abstract

The invention discloses a square bundle straw crusher capable of achieving blending cutting and beating secondary crushing. The crusher comprises a base, a motor and a shell are mounted on the base, the shell is connected with a discharge pipe and a feed port, a crushing mechanism is mounted in the shell, and the square bundle straw crusher is characterized in that the crushing mechanism is directly connected and driven by the motor, and an impeller, a hammering cutting mechanism and a blending cutting mechanism are mounted on an extension shaft of the motor. A crushing chamber is further installed outside the hammering cutting mechanism in the machine shell, and a screen is additionally installed in the crushing chamber. The straw crusher belongs to the type of processing coarse and hardstraw, is suitable for coarse and hard dry straw, and can meet the requirement of crushing coarse and hard dry and wet square baled straw. The crusher has important practical significance and good development prospect for improving the mechanization level of straw resource utilization in China and promoting the development of the cattle and sheep industry.

Description

technical field [0001] The invention relates to a crushing machine for agriculture and animal husbandry, in particular to a square bale straw grinder with stirring, cutting and beating secondary crushing. Background technique [0002] Animal husbandry based on cattle and sheep is a traditional industry and a pillar industry in Xinjiang's agricultural and pastoral areas. It is an important way for farmers and herdsmen to get rid of poverty and become rich, and it is also an important foundation for the survival and development of the ethnic minorities in Xinjiang. At the same time, Xinjiang is a large agricultural province with rich straw resources of major crops, which can support and guarantee the development of cattle and sheep industries. [0003] Corn stalks, wheat straw, and rice straw are the main roughages for cattle and sheep breeding in my country and Xinjiang, and also an important guarantee for the vigorous development of grain-saving animal husbandry in my countr...

AI Technical Summary

Problems solved by technology

The main problems in the crushing of square bales of straw: First, manual loose baling and manual feeding are required for square bales of straw, which generally have the problems of low productivity, high energy consumption, high labor intensity, and poor operation safety.

Second, the processing quality is poor

The corn stalks, wheat straws and straws processed by the hay cutter are generally more than 3 centimeters in length, most of them are about 5 centimeters, and some are even longer, which can meet the needs of beef cattle breeding, but it is difficult to reach the optimal length of less than 2 centimeters required by mutton sheep

The third is that the straw can be wet or dry, hard or soft, thick or thin. Existing machines cannot be subdivided for processing, resulting in low processing efficiency if it is too thick or too hard, or high energy consumption due to high-power machines processing fine and soft straw. , wasting energy
