Description

An agricultural shredder

technical field

The utility model relates to the field of agricultural technology, in particular to an agricultural pulverizer.

Background technique

In agricultural production, it is often necessary to crush crops, such as peppers, straw, etc., which requires the use of a grinder. For some existing grinders, usually only some soft crops can be crushed. Hard crops will generate a lot of heat, which will not only damage the machine, but also may affect the materials, and ordinary grinders can only crush a single crop, and cannot achieve the purpose of mixing and crushing. If crushing one by one, the process will be more , increased production costs. At the same time, when the crops are crushed, hard debris such as stones and metal objects may be mixed in, which may easily damage the rotary knife, or even block the gap between the rotary knife and the fixed knife, so that the rotary knife cannot rotate, causing the motor to burn and damage. Just have to shut down for maintenance, which is labor-intensive and time-consuming, the production cost is high, and the production efficiency is low.
