[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides an embodiment: a raw material crushing device used for pigment production, comprising:

[0025] A machine body 1, wherein a main shaft 3 is arranged inside the machine body 1, and a crushing roller 4 is fixedly connected to the outer wall of the main shaft 3;

[0026] The protective component 2 includes a protective cover 21, which is fixedly connected to the top of the body 1. The inner wall of the protective cover 21 is fixedly connected to a support shaft 22, and the outer part of the support shaft 22 is rotatably connected to a protective plate 23. One side of the protective plate 23 is fixedly connected to a guide column 24, and the outer sleeve of the guide column 24 is provided with a guide sleeve 25, and the guide sleeve 25 is fixedly connected to the inner wall of the protective cover 21. An arc spring 26 is provided inside the guide sleeve 25. The protective cover 21 is connected to an end cover 27 corresponding to the guide sleeve 25. Through the setting of this structure, the feeding part of the device can be covered and protected, thereby effectively avoiding the splashing of gravel at the feeding part and avoiding the dispersion of dust, thereby improving the safety and convenience of the device when feeding.

[0027] Furthermore, the top of the protective cover 21 is an inclined structure, and the bottom of the inclined structure abuts against the surface of the protective plate 23 . The arrangement of this structure mainly plays a role in assisting the positioning of the protective plate 23 .

[0028] Furthermore, three groups of stepped positioning holes are opened on the upper surface of the protective cover 21, and the interior of the stepped positioning holes is connected to the end cover 27 by countersunk bolts. The disassembly and assembly structure of the end cover 27 makes it easy to replace the wearing arc spring 26 of the device, further improving the convenience of subsequent maintenance of the device.

[0029] Furthermore, the guide column 24 and the guide sleeve 25 are both in an arc-shaped structure, and the center of the guide column 24 and the guide sleeve 25 are in the same position as the center of the support shaft 22. The guide column 24 is in a step-shaped structure, and the guide column 24 and the guide sleeve 25 are in a limited sliding insertion. Through the auxiliary sliding of the guide column 24 and the guide sleeve 25, the opening and closing of the protective plate 23 are further guided and limited. At the same time, with the setting of the internal arc spring 26, the stable resetting of the protective plate 23 is achieved.

[0030] Furthermore, the main shaft 3 is rotationally connected to the machine body 1 via a bearing, and the ends of the two main shafts 3 are connected to a driving motor for rotationally driving the main shaft 3 and the crushing roller 4 .

[0031] Furthermore, the inner wall of the protective cover 21 is fixedly connected with a guide plate 5, and the upper surface of the guide plate 5 is inclined. Through the setting of the guide plate 5, it further plays an auxiliary guiding role for the added material, preventing the material from falling directly onto the surface of the crushing roller 4, and reducing the impact of its falling. The protective cover 21 is provided with a first flange at one end close to the guide sleeve 25, and threaded holes are evenly opened on the first flange. The outer wall of the guide sleeve 25 is provided with a second flange, and positioning holes are evenly opened on the second flange. The end of the end cover 27 close to the guide sleeve 25 is stepped, and the end cover 27 and the arc spring 26 abut against each other.

[0032] Working principle: the body 1, main shaft 3 and crushing roller 4 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, the device is first installed and assembled. When the device is in use, the external drive motor is first driven to rotate the main shaft 3 and the crushing roller 4, and the material is added through the top opening of the protective cover 21. During the process of adding materials, the protective plate 23 is opened by gravity, so that the material falls into the inside of the protective cover 21 until it falls on the crushing roller 4 for crushing. After the material is added, the protective plate 23 is affected by the elasticity of the guide column 24 and the arc spring 26, and contacts with the protective cover 21, so as to achieve sealing at the feed inlet, thereby improving the safety of the feeding point of the device.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
