The linear moving assembly 3 moves along the extending direction of the feeding channel of the feeding bin 2; the clamping component 5 is arranged on the L-shaped bracket 4; is communicated with a crushing space in the crusher body 1; the L-shaped bracket 4 is used for clamping straw raw materials along with the linear clamping component 5 and is gradually fed into the crushing space of the crusher body 1; through the arrangement, the L-shaped bracket 4 is positioned at the inlet end of the feeding bin 2; then the clamping component 5 is opened and clamped after the straw raw materials are put in; then the clamped straw raw materials are gradually moved by the linear moving assembly 3 and enter the crushing space, and the materials are fed at a constant speed in the process, so that the crushing device outputs with optimal output power; and the clamping component 5 and the linear moving component 3 feed materials, so that the risk caused by manual feeding is avoided.
Among them, it should be understood that: the bottom surface of the inner wall of the feeding bin 2 is an inclined surface, and the height of an inlet of the feeding bin 2 is higher than that of an outlet of the feeding bin 2; the crushing space is the space required by the part of the crusher body 1 for crushing the straw during high-speed rotation, and the clamped part of the straw raw material fed in the crushing space enters the crushing space under the action of dead weight after loosening.
In some preferred embodiments, a chute 6 is arranged on the bottom surface of the inner wall of the feeding bin 2;
the linear moving assembly 3 comprises a telescopic rod 300 and a sliding block 301 which is arranged in the sliding groove 6 in a sliding way; the telescopic end of the telescopic rod 300 is fixedly connected with the sliding block 301, and the fixed end of the telescopic rod 300 is connected with the inlet of the feeding bin 2; the sliding block 301 is fixedly connected with one side of the L-shaped bracket 4.
The number of the sliding grooves 6 is two; the number of the telescopic rods 300 is two; the sum of the maximum length of the extension rod 300 and the length of the sliding block 301 is smaller than the length of the sliding groove 6.
The risk of the slide 301 falling out of the slide groove 6 is avoided by the above arrangement, and the moving distance is changed by the length change of the telescopic link 300, wherein the moving speed can be controlled by the length change rate of the telescopic link 300. The sliding groove 6 and the sliding block 301 also make the moving track stable. After the telescopic rod 300 reaches the maximum extension length and reaches the set time, the reset is automatically performed, and the next feeding operation is started.
In some preferred embodiments, describing the specific structure of the clamping assembly 5, the clamping assembly 5 is to clamp after sensing a certain weight of straw, and the following settings are provided:
