Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crushers, in particular to an inner protective lining plate of a high-calcium stone three-eight tooth roller crusher. Background Art
[0002] Double-toothed roller crushers are commonly used for crushing stone and building materials, suitable for crushing various ores and construction waste. High-calcium stone fragments are 3-8cm in size. When a double-toothed roller crusher is in operation, stone material is fed through the feed port at the top of the crushing chamber. The relative rotation of the two toothed rollers compresses the stone, breaking it into fragments of the corresponding particle size. During the crushing process, the stone tends to disperse toward the ends along the gap between the two crushing rollers. Therefore, the inner wall of the crushing chamber corresponding to the center of the two crushing rollers is subjected to significant impact, resulting in rapid wear in this area.
[0003] In the prior art, an integral protective plate is usually arranged on the side wall of the box. The protective plate roughly overlaps with the side wall of the box and has a large area. However, since the position where the protective plate is impacted is relatively fixed, when the corresponding position is deformed or severely worn due to impact, its protective function can only be restored by replacing the integral protective plate. However, the larger protective plate is not only inconvenient to disassemble but also difficult to install; and its undamaged area is much larger than the worn area, so replacing the integral protective plate will cause great waste.

[0023] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-Figure 4 As shown, the utility model provides a protective liner inside a high-calcium stone three-eight tooth roller crusher, comprising a crushing box 1, a feed port 3 being provided in the middle of the top of the crushing box 1, two tooth rollers 4 being provided inside the crushing box 1, and a removable liner 2 being provided on each side wall of the crushing box 1, the removable liner 2 being fixedly connected to the crushing box 1 by bolts, and the position of the removable liner 2 corresponding to the gap between the two tooth rollers 4; when the two tooth rollers 4 counter-rotate to crush the stone, the stone moves along the gap between the two tooth rollers 4 toward the side wall of the crushing box 1 after being impacted, and contacts and collides with the removable liner 2; after the removable liner 2 is worn to a certain thickness or deformed, the protective performance inside the crushing box 1 can be restored by removing and replacing the removable liner 2;
[0025] Two side guard plates 5 are respectively provided on both sides of the interior of the crushing box 1, and the side guard plates 5 are fixedly connected to the crushing box 1 by bolts. The two side guard plates 5 are respectively provided on both sides of the removable liner 2, and the surface of the side guard plates 5 is flush with the surface of the removable liner 2. After the tooth roller 4 is installed, the end of the roller should maintain a small distance from the inner wall of the crushing box 1. If only the removable liner 2 is provided without the side guard plates 5, the distance between the end of the tooth roller 4 and the inner wall of the crushing box 1 will be large, which will easily cause stones to fall and dust to accumulate. After the side guard plates 5 and the removable liner 2 are set to be flush with the surface, the gap between the tooth roller 4 and the inner wall of the crushing box 1 can be eliminated as much as possible.
[0026] The removable lining 2 includes a main lining 21, which is the main body that bears the impact of the stone and mainly plays a protective role. The two sides of the main lining 21 are respectively connected to the two side guard plates 5 and the surfaces are flush. The main lining 21 is stuck between the two side guard plates 5 to reduce the swing of the main lining 21;
[0027] A hanger 23 is provided on the top of the main lining plate 21. The hanger 23 is used to facilitate the positioning of the main lining plate 21. The hanger 23 is hung on the top edge of the side wall of the crushing box 1. After the hanger 23 cooperates with the side wall at the feed port 3 of the crushing box 1, it can serve as the top positioning of the main lining plate 21 and prevent the main lining plate 21 from falling after the bolts fixing the main lining plate 21 are removed. The hanger 23 is composed of a top plate and a hanging plate. One side of the top plate is fixed to the upper edge of the main lining plate 21, and the hanging plate is fixed to the bottom side of the top plate. A lifting ring 22 is provided on the hanger 23. The lifting ring 22 is used for lifting the main lining plate 21 to facilitate the disassembly and assembly of the main lining plate 21.
[0028] The lifting ring 22 is arranged in the middle of the outer side of the hanging bracket 23. After such arrangement, the lifting ring 22 can not only be used as a lifting ring, but also as a handle for workers to climb the equipment.
[0029] Two rows of fixing holes 24 are provided on the main lining plate 21, and the two rows of fixing holes 24 are symmetrically distributed on both sides of the main lining plate 21, and the distance between the fixing holes 24 and the edge of the main lining plate 21 is less than the spacing between the two rows of fixing holes 24. With this arrangement, there is no fixed point at the gap position facing the two tooth rollers 4, which can reduce the impact on the fixing bolts, increase the service life of the bolts, and improve the stability of the fixation of the main lining plate 21.
[0030] The above structure is adopted, by setting the side guard plate 5 and the removable lining plate 2 as a split structure, a clamping groove matching the removable lining plate 2 is formed between the two side guard plates 5 on the same side, and the removable lining plate 2 is located in the clamping groove. After the removable lining plate 2 is installed, the surface of the main lining plate 21 is flush with the surface of the side guard plate 5; during the operation of the crusher, only the removable lining plate 2 is impacted by the stone, and the side guard plate 5 is almost not impacted. Therefore, wear and deformation only occur at the removable lining plate 2, so that the protective function of the crushing box 1 wall can be restored by simply replacing the removable lining plate 2, which can greatly reduce the protection cost of the box wall; by setting the hanging bracket 23, the hanging bracket 23 can be hung on the box wall of the crushing box 1, which is convenient for positioning and locking the main lining plate 21, and can also prevent the main lining plate 21 from falling during use. In conjunction with the lifting ring 22, the main lining plate 21 can be conveniently lifted, thereby improving the disassembly and assembly efficiency of the removable lining plate 2 and reducing the downtime of the equipment.
[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
