technical field

The invention belongs to the technical field of crop crushing devices, in particular to a guillotine crusher with a built-in counterweight to increase the moment of inertia.

Background technique

Forage grass and crop straw not only contain various nutrients necessary for livestock, but also contain crude fiber which is particularly important for maintaining the health of ruminant livestock, which cannot be replaced by grain and other feeds. On the other hand, the pros and cons of pasture varieties and the quality of crushing and processing have an important impact on the consumption and absorption of livestock, which in turn affects the development of the livestock industry.

At present, forage grinders are generally used to process the harvested forage. In order to improve the pulverizing effect of forage grass, a motor with higher power is required to bring a wheel pulverizing device, which has high energy consumption and high cost. For many farmers, they prefer to support small 220V motors. When the existing forage pulverizer is driven by a motor with low power, if the forage feeds a lot, it is easy to crash, which affects the normal operation of the pulverizer.

On the other hand, in the existing forage pulverizer, a feeding device is installed in front of the pulverizing cavity, and the feeding device generally includes a feeding roller and a driving roller that are oppositely arranged up and down. With cooperation, the forage is clamped and transported to the crushing cavity. That is, the motor of the forage pulverizer not only drives the pulverizing device in the pulverizing cavity to rotate and pulverizes the forage, but also drives the feeding roller and the driving roller of the feeding device to rotate, which consumes a lot of energy.
