[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0024] It should be noted that: Similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0025] This embodiment mainly elaborates on the title of the tooth plate applicable to small-particle materials, specifically as follows:

[0026] Currently, tooth plates are all in a waveform structure, that is, a number of equally spaced and parallel raised strips are provided on the surface. When crushing, the material is crushed at the gaps between the raised strips and slides down along the gaps between the raised strips. This structure is only applicable to large-particle materials and cannot crush the material into small particles.

[0027] In view of the above problems, this embodiment provides a tooth plate applicable to small-particle materials. Referring to the attached Figure 1 , it includes a tooth plate body 10. The front surface of the tooth plate body 10 has a crushing surface for crushing the material, and a number of strip-shaped grooves 102 formed by concave are provided on the crushing surface. This solution improves the conventional waveform teeth into a planar type, and through the extrusion of the crushing plane and the cutting of the edge edges of the grooves, small materials are crushed.

[0028] Preferably, a number of parallel and equally spaced first groove groups 1021 are provided on the front surface of the tooth plate body 10. The first groove group 1021 includes a number of collinear first strip-shaped grooves.

[0029] Preferably, a number of the first strip-shaped grooves in the first groove group 1021 are arranged at equal intervals. Setting the first strip-shaped grooves as a discontinuous structure can avoid the formation of grooves for the material to slide out, that is, the material can only fall from the edge of the crushing surface after being crushed by the crushing surface, thereby ensuring the crushing degree to the greatest extent.

[0030] Preferably, the first groove group 1021 forms an acute angle with the left edge of the front surface of the tooth plate body 10.

[0031] Preferably, a number of parallel and equally spaced second groove groups 1022 are provided on the front surface of the tooth plate body 10. The second groove group 1022 includes a number of collinear second strip-shaped grooves.

[0032] Preferably, several second strip-shaped grooves in the second groove group 1022 are arranged at equal intervals, and the spacing of the second groove group 1022 is the same as that of the first groove group 1021.

[0033] Preferably, the second groove group 1022 forms an acute angle with the left front edge of the tooth plate body 10.

[0034] Preferably, the first groove group 1021 and the second groove group 1022 form a 90-degree angle.

[0035] Preferably, the lengths and widths of the first strip-shaped groove and the second strip-shaped groove are the same. The first groove group 1021 and the second groove group 1022 form a groove similar to a net, which has the characteristic of high uniformity, and high uniformity will bring a more uniform crushing effect.

[0036] As Figure 2 and 3 shown, an installation structure is provided on the back surface of the tooth plate body 10. The installation structure includes a rectangular first annular boss 103 arranged at the edge of the back surface of the tooth plate body 10 and a rectangular second annular boss 104 arranged inside the first annular boss 103. There is a spacing between the second annular boss and the first annular boss 103. A number of groups of installation holes 101 for fixing are provided on the first annular boss 103 and the second annular boss 104. In this embodiment, at least one group of installation holes 101 is provided on each of the front, back, left, and right surfaces. The installation hole 101 is a stepped hole, and a fixing nut is embedded at the inner end of the stepped hole. The structure in this solution is used for installation and fixation. When fixing, place two nuts in the stepped hole and buckle the installation structure onto the crusher body. There is a rectangular boss 201 and an annular boss 202 on the crusher body. The rectangular boss 201 extends into the groove inside the second annular boss 104, and the annular boss extends into the gap between the first annular boss 103 and the second annular boss 104. The rectangular boss 201 and the annular boss 202 can limit the nuts, and then tighten and fix by inserting bolts into the installation holes 101. After buckling, the first annular boss 103 and the second annular boss 104 have a limit in the direction perpendicular to the buckling direction, and the limit in the buckling direction is achieved by bolts. During use, the force borne is mainly the force perpendicular to the buckling direction. Therefore, compared with the structure directly fixed by bolts, this structure has stronger stability during use.

[0037] It should be noted that the edge of the strip-shaped groove 102 shown in the drawing is in a racetrack shape. In addition, affected by the size of the crushing surface, the length of the groove at the edge of the crushing surface is less than the length of the normal groove in the middle. In order to ensure that the lengths of the grooves are consistent, the length and width of the tooth plate can be increased adaptively.

[0038] The above has introduced the title provided by the present utility model in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
