[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] For example, please refer to the attached Figure 1-3 A raw material crushing device for processing wood fiber includes a crushing box 1, wherein the crushing box 1 is rotatably connected to a symmetrically arranged crushing roller 2, and the top of the crushing box 1 is connected to a dust-proof feeding mechanism 3;

[0026] The dustproof feeding mechanism 3 includes a dustproof cover 31 connected to the upper surface of the crushing box 1 and a feeding channel 32 connected to both ends of the top of the dustproof cover 31. The feeding channel 32 is connected to a quantitative component 33.

[0027] For details, please refer to the attached Figure 1 and 2 , the inner cavity of the feed channel 32 is connected to the inner cavity of the dust cover 31;

[0028] The quantitative assembly 33 includes a support frame 331 connected to the upper surface of the feed channel 32, an electric push rod 332 connected to the upper surface of the support frame 331, and a blocking plate 333 connected to the execution end of the electric push rod 332;

[0029] A long hole is provided at the top of the feed channel 32, and the long hole is used for the blocking plate 333 to pass through;

[0030] It should be noted that, in this embodiment, since the inner cavity of the feed channel 32 is connected to the inner cavity of the dust cover 31, the wood fiber raw material entering the feed channel 32 can quickly enter the dust cover 31 along the inclined feed channel 32;

[0031] Furthermore, the support frame 331 provides support for the electric push rod 332, and the electric push rod 332 drives the blocking plate 333 so that the blocking plate 333 can be raised and lowered, and the blocking plate 333 blocks the conveying channel of the feed channel 32, thereby preventing too much wood fiber raw material from entering the crushing box 1 and affecting the crushing work of the crushing roller 2 in the crushing box 1.

[0032] For details, please refer to the attached Figure 2 and 3, the support frame 331 has a slide groove 334 on both sides of the frame, the slide groove 334 is slidably connected to the slide block 335, and the slide block 335 is connected to the top of the adjacent side of the blocking plate 333;

[0033] The bottom end of the blocking plate 333 is provided with a groove 3331, and a conveying roller 3332 is rotatably connected to the groove 3331;

[0034] The blocking plate 333 is a hollow structure, and a motor 3333 is connected to the inside of the blocking plate 333 , and the output end of the motor 3333 is connected to the conveying roller 3332 ;

[0035] It should be noted that, in this embodiment, the sliding of the slider 335 is guided by the sliding groove 334 so that the blocking plate 333 connected to the slider 335 can slide stably;

[0036] Furthermore, the groove 3331 accommodates the conveying roller 3332. When the conveying roller 3332 rotates, the wood fiber raw material can be pushed to move when the blocking plate 333 is lifted, thereby accelerating the wood fiber raw material to enter the dust cover 31.

[0037] Furthermore, the motor 3333 drives the conveying roller 3332 connected thereto.

[0038] The specific operation mode of the utility model is as follows:

[0039] When crushing the wood fiber raw material, the raw material is placed in the feed channel 32. Since the inner cavity of the feed channel 32 is connected to the inner cavity of the dust cover 31, the wood fiber raw material entering the feed channel 32 can quickly enter the dust cover 31 along the inclined feed channel 32. The raw material falling from the inner cavity of the cover enters between the two crushing rollers 2 and is crushed by the crushing rollers 2 rotating in opposite directions.

[0040] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
