[0003] The known authorized patent application number is: CN202321718041.5, which discloses a crusher screen plate. Its background technology raises the problem that "the existing installation method of the screen plate is to connect it to the crusher in a clip-on manner, but this connection method will affect the stability of the screen plate, thereby affecting the use efficiency of the equipment." Therefore, the technical solution to this problem is "including a main body plate, and the upper left part and the upper right part of the main body plate are each provided with a group of sieve holes that pass through up and down, the two groups of sieve holes are symmetrically distributed on the left and right sides, and each group is set to multiple, and the multiple sieve holes are distributed at equal distances, and a connecting frame is provided in the middle of the front end and the middle of the rear end of the main body plate, and the front and rear ends of the lower end of the main body plate are fixedly installed with support frames" and so on.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: although the effect of stable installation of the sieve plate is achieved through the provided technical solution, it is not convenient to ensure the fluidity of the material through the sieve holes when in use. Since the width structural dimensions of the strip sieve holes are consistent, when the material passes through the sieve holes, it is easy for the material to be stuck in the sieve holes and accumulate, which can easily cause the sieve plate to be blocked, thereby reducing the use effect and screening efficiency of the sieve plate. Utility Model Content

[0005] The utility model provides a sieve plate for a crusher, which solves the problem in the related art that it is difficult to ensure the fluidity of the material passing through the sieve holes.

[0007] A plurality of strip-shaped sieve holes are evenly arranged on the surface of the main body plate in a staggered manner, wherein the cross-sectional width of the strip-shaped sieve holes increases from top to bottom to form a tapered structure, that is, the top surface of the strip-shaped sieve holes is the small hole end, and the bottom surface of the strip-shaped sieve holes is the large hole end;

[0008] And a supporting mechanism is arranged at the bottom of the main body plate for improving its bearing capacity.

[0009] Preferably, the connecting mechanism includes a docking block that is clamped in the groove, and a connecting block that is fixedly installed on one side of the docking block and is in an inverted U shape. Two sets of corresponding screw holes are symmetrically opened on the inner bottom wall of the groove and the bottom of the docking block, and two screw holes are symmetrically opened on the top of the connecting block. Fixing bolts are threadedly connected in screw hole two and screw hole one.

[0010] Preferably, an annular groove is provided on one end surface of the fixing bolt head, a rubber gasket is sleeved on the surface of the fixing bolt, and a clamping ring that is clamped with the annular groove is fixedly mounted on one end surface of the rubber gasket.

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

[0024] Example 1

[0025] See also Figure 1 - Figure 6 The utility model provides a screen plate for a crusher, comprising: an arc-shaped main body plate 1, grooves 5 are provided on both sides of the main body plate 1, and a connecting mechanism for installing the main body plate 1 is provided in the groove 5;

[0026] A plurality of strip-shaped sieve holes 2 are evenly arranged on the surface of the main plate 1 in a staggered manner, wherein the cross-sectional width of the strip-shaped sieve holes 2 increases from top to bottom in a tapered structure, i.e., the top surface of the strip-shaped sieve holes 2 is a small hole end 3 facing the crushing cavity, and the bottom surface of the strip-shaped sieve holes 2 is a large hole end 4 away from the crushing cavity;

[0027] And a supporting mechanism is provided at the bottom of the main body plate 1 for improving its bearing capacity.

[0028] The technical solution provided by this embodiment is as follows: when in use, the main plate 1 is conveniently installed inside the crusher for use by utilizing the connecting mechanism, and it is also convenient to disassemble, which is convenient for later maintenance of the main plate 1. Under the action of the supporting mechanism, the bearing capacity of the main plate 1 can be improved, which is convenient for enhancing the stability of use and extending the service life of the main plate 1. When the crusher crushes the material, the crushed material can be screened through the strip sieve hole 2. Since the strip sieve hole 2 has a taper and is divided into two parts, a small hole end 3 and a large hole end 4, the crushed material will enter the strip sieve hole 2 through the small hole end 3. The channel of the large hole end 4 gradually expands, so the material can be discharged smoothly from the large hole end 4, making it difficult for the material to accumulate and get stuck in the strip sieve hole 2. Even if a small amount of material is temporarily stuck at the small hole end 3, the subsequent vibration of the crusher and the flow of the material can push it to the large hole end 4 to increase the gap with the hole wall for discharge. Therefore, the strip sieve hole 2 is prevented from being blocked and its material flowability is ensured, avoiding the situation where the strip sieve hole 2 is easily blocked by accumulated materials due to the consistent aperture width, ensuring that the crushed material can be discharged from the crushing cavity in time, and effectively improving the screening effect of the main plate 1 and the working efficiency of the crusher.

[0029] Furthermore, the connecting mechanism includes a docking block 6 that is clamped in the groove 5, and a connecting block 7 that is fixedly installed on one side of the docking block 6 and is in an inverted U shape. Two sets of corresponding screw holes 8 are symmetrically provided on the inner bottom wall of the groove 5 and the bottom of the docking block 6. Two screw holes 9 are symmetrically provided on the top of the connecting block 7. Fixing bolts 10 are threadedly connected in screw holes 9 and screw holes 8.

[0030] Specifically, when installing the main plate 1 in the crusher, the docking block 6 is inserted into the groove 5 for clamping, and the fixing bolt 10 is screwed into the screw hole 1 8 to fix the docking block 6. Then, the connecting block 7 is docked with the installation position inside the crusher, and the fixing bolt 10 is screwed into the screw hole 2 9 to connect with the internal structure of the crusher. The main plate 1 can be installed and fixed by using the fixing bolt 10 to enhance the installation stability of the main plate 1.

[0031] Furthermore, the support mechanism includes two support frames 13 symmetrically fixedly installed at the bottom of the main body plate 1, and two arc-shaped support blocks 15 symmetrically arranged between the two support frames 13 and adapted to the shape of the main body plate 1. Two groups of card slots 14 are symmetrically opened on the two support frames 13, and the two arc-shaped support blocks 15 are respectively clamped inside the two groups of card slots 14.

[0032] Limiting grooves 16 are provided on both sides of the inner wall of the slot 14, and two limiting ear plates 17 that are engaged with the limiting grooves 16 are symmetrically fixed on both ends of the arc-shaped support block 15. Corresponding locking screw holes are provided on the end faces of the limiting ear plates 17 and the inside of the limiting groove 16, and the locking screw holes are threadedly connected with locking screws 18.

[0033] Specifically, before installing the main plate 1 inside the crusher, the arc-shaped support block 15 is clamped in the clamping groove 14, and at the same time, the limiting ear plate 17 and the limiting groove 16 are clamped for the second time to improve the clamping stability between the arc-shaped support block 15 and the support frame 13. Then, the locking screw 18 is screwed into the locking screw hole to lock and fix the arc-shaped support block 15 and the support frame 13. In this way, the arc-shaped support block 15 can be used to support the main plate 1, thereby achieving the effect of improving the bearing capacity of the main plate 1, which is beneficial to extending the service life and stability of the main plate 1.

[0034] Example 2

[0035] Based on Example 1, in this embodiment: an annular groove is provided on one end face of the screw head of the fixing bolt 10, a rubber gasket 11 is sleeved on the surface of the fixing bolt 10, and a clamping ring 12 is fixedly installed on one end face of the rubber gasket 11 to be clamped with the annular groove.

[0036] The technical solution provided by this embodiment is: when tightening the fixing bolt 10, the rubber gasket 11 is put on the fixing bolt 10, and the clamping ring 12 and the annular groove are clamped to limit the position of the rubber gasket 11 and prevent the rubber gasket 11 from moving, so as to ensure the accuracy and fixity of the position of the rubber gasket 11 after the fixing bolt 10 is locked. At the same time, the rubber gasket 11 can buffer the vibration force exerted on the fixing bolt 10, avoiding the loosening of the fixing bolt 10 due to vibration during the use of the crusher, which affects the installation of the main plate 1, thereby effectively improving the installation firmness and stability of the main plate 1.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
