Description
Technical Field
[0001] The utility model belongs to the field of agricultural waste treatment and relates to a crushing device, in particular to a crop stalk crushing device. Background Art
[0002] Crop stems are not only good fertilizers for planting, but also good food for livestock. When processing crop stems, they need to be crushed, which is usually done using a crusher.
[0003] For example, the utility model patent with the authorization announcement number CN 214811240 U discloses an agricultural and forestry stem crusher, including a frame, a feeding bin rotatably connected to the frame, a crushing device located directly below the feeding bin, and a discharging conveyor belt located below the crushing device. By setting the feeding bin, the crushing device, and the discharging belt, the stems are crushed instead of manually, which improves efficiency, reduces labor intensity, and enhances the crushing effect. For another example, in the invention application with the application number CN 103537347 A, a double-knife roller straw crusher is disclosed, including a feed hopper, a crushing chamber arranged below the feed hopper, and a crushing collection hopper arranged below the crushing chamber. By adjusting the distance between the grille and the crushing roller, the purpose of controlling the size of the fine particles of the crushed plant stems is achieved, and at the same time, it can also effectively prevent large pieces of plant stems from falling directly into the crushing collection hopper without being crushed. For another example, the utility model patent with the authorization announcement number CN 220307821U discloses a corn harvester stalk crushing device, including a corn harvester crushing body and a stalk crushing mechanism arranged on a stalk collection area plate. By providing a waste collection component, the crushed stalks can be collected and processed in a centralized manner, and the convenience of subsequent operations is improved, so that the crushed stalks can be cleaned in time, and subsequent accumulation is not easy to avoid blockage. Undoubtedly, these crushing or crushing devices not only improve the crushing efficiency but also enhance the crushing effect.
[0004] However, the objects to be crushed are either dry stems containing dirt, dust and other impurities, or freshly cut green stems containing water. When crushing or pulverizing dry stems, the dry stems are directly filled into the feeding port of the crushing device or the pulverizing device, which will inevitably cause dust and other impurities to fly during the crushing or pulverizing process, which is not good for the health of the operator. As for green stems, the water content in the green stems is high and the flexibility is large. Therefore, when crushing or pulverizing, the juice splashes, which on the one hand may easily cause poor lubrication of the crusher's rotating shaft and affect the service life of the crusher; on the other hand, due to its greater flexibility, it may not be crushed properly when crushing or pulverizing.
