Technical Field
The invention relates to a differential mulberry strip crushing device, and belongs to the field of agricultural machinery and equipment. Can be used for crushing mulberry twigs, and also can be used for crushing branches of fruit trees and other branches.
Background
The mulberry has rich nutrient content and contains various substances beneficial to human body. For the traditional silkworm breeding mode, mulberry leaves are mainly utilized, and mulberry strips are not well utilized. The emerging industry of cultivating mushrooms by mulberry strips is a good solution for comprehensive utilization of mulberry trees.
Compared with the traditional matrixes such as corncob and the like, the mulberry strip matrix has much higher protein and other nutrient contents, is more suitable for mushroom cultivation, and modern researches show that the mulberry is internally provided with a plurality of substances beneficial to human bodies, which is also the reason why mulberry leaf tea is popular. The nutrient substances are also rich in the fresh mulberry strips, and the mushrooms cultivated by taking the crushed mulberry strips as cultivation matrixes are rich in nutrition. The mushrooms are taken as decomposers to participate in decomposing mulberry strips, so that macromolecular organic matters in the mulberry strips are decomposed, and the remaining decomposed mulberry strips after cultivation are also a very good organic fertilizer.
However, the cultivation of mushrooms by mulberry leaves is an emerging industry, and it is difficult for farmers to buy a pulverizer for mulberry leaves. Farmers can only purchase a pulverizer for pulverizing grains or branches; the existing branch pulverizer is mainly used for pulverizing branches, is used for making wood products or making paper pulp, and has poor mushroom cultivation effect by using mulberry strips pulverized by the existing grain pulverizer and the branch pulverizer.

In order to achieve the purpose, the invention adopts the following technical scheme:
a differential mulberry strip crushing device comprises a crushing chamber, a cutter Duan Dao, a crushing hammer device and a frame; the frame is used for fixing the crushing chamber;
the crushing chamber comprises a discharge chamber, an upper crushing chamber and a lower crushing chamber; the lower crushing chamber is arranged on the frame, and the upper crushing chamber and the lower crushing chamber can be movably connected into a whole; the top of the upper crushing chamber is connected with a discharge chamber; the upper crushing chamber is detachable; the discharge chamber, the upper crushing chamber and the lower crushing chamber form a crushing chamber with a hollow inside; a feeding port is arranged at the joint of the lower part of the upper crushing chamber and the lower crushing chamber, and is connected with a feeding cylinder; the main shaft comprises a solid main shaft and a hollow shaft, the hollow main shaft is movably sleeved outside the solid main shaft, and the solid main shaft and the hollow main shaft can rotate. A radial sliding bearing is arranged between the solid main shaft and the hollow shaft and is used for reducing friction and heating caused by different rotation speeds of the solid main shaft and the hollow shaft. One end of the hollow main shaft is positioned by a thrust ball bearing, friction between the hollow main shaft and the solid main shaft is reduced, and the other end of the hollow main shaft is positioned by a bearing and a bearing seat. The solid main shaft and the hollow shaft are respectively connected with independent belt wheels for driving, so that adjustment of different rotation speeds is realized, and differential crushing is performed; two ends of the solid main shaft are respectively fixed on the bearings with seats at two sides of the frame through a first deep groove ball bearing and a second deep groove ball bearing; one end of the hollow main shaft and the solid main shaft are coaxially fixed on the deep groove ball bearing I; the other end is coaxially fixed on a bearing with a seat on the frame through a second deep groove ball bearing;

Conversely, the too high rotational speed of the crushing hammer can cause the machine body to generate huge vibration and noise, which affect the use comfort and health of workers and also reduce the service life of the crusher. According to the invention, through a special differential structure, the cutting knife and the crushing hammer are independently driven, so that differential operation of the cutting knife and the crushing hammer is realized. The cutting quality is guaranteed by setting the higher rotating speed of the sectioning knife, and meanwhile, the lower rotating speed of the crushing hammer is set, so that the crushing hammer is prevented from rotating at a high speed to generate larger vibration and noise. By controlling differential transmission of the cutting part and the crushing part, the invention can effectively reduce the running vibration and noise of the machine body while guaranteeing the cutting quality.
The invention has the beneficial effects that:
1: is suitable for crushing fresh mulberry strips, and adopts differential design to reduce power loss and vibration and noise generated in the running process of the crusher.
2: the special design smash hammer structure can strengthen the crushing effect to the mulberry strip.
