[0002] The vulnerable part of hammer crusher is grate plate. The main reason of grate plate damage is the impact and wear of materials. When hard materials or unbreakable materials enter the crushing chamber, the grate plate will be blocked. The materials in the crushing chamber will increase the load of grate bars, which may cause grate plate damage.

[0003] The prior art discloses a novel anti-blocking material discharging grate plate (CN201120470601.0), comprising a grate plate body, a cone section, a material retaining entity, a grate hole, a half-width cavity and an arc plate, wherein the cone section is a convex surface of one-third of the cone, which is embedded in the raised surface of the grate plate body and overlaps with the grate plate body; the arc plate is an enlarged end portion extending from the cone section, connected to the arc of the mill cylinder to form a side cone triangle; the material retaining entity is designed opposite to the half-width cavity on the inner side of the cone section; the grate hole has a powder flow area that is 1.5 times greater than the powder flow area of ​​the original grate plate grate hole design.

[0004] After searching, it was found that the device used a conical structure with flat sides, which makes it easy for the material to stagnate on the plane instead of sliding down during use; in addition, the material discharging speed is different, and the device does not clearly point out this aspect. If the material discharging speed is not controlled, it may cause friction between the materials during use, thereby reducing the discharging speed and causing stagnation and blockage; in addition, since the grate plate is the main impact object of the material, it is subjected to huge impact force, so the device does not have a stable connection method in terms of fixing and connection, which easily causes the grate plate to be damaged by impact.

The following embodiments are used to illustrate the utility model.

[0027] An anti-blocking grate plate assembly, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a top grate plate 10, and a vibrating screening structure for vibrating materials is arranged at the bottom of the top grate plate 10. The vibrating screening structure includes a vibrating structure and a screening structure. The vibrating structure includes a blocking box 11, a bottom grate plate 15 and a resistance box 22. The blocking box 11 is clamped to the bottom grate plate 15 and is disassembled to connect the resistance box 22. The resistance box 22 is fixedly connected to the top grate plate 10; the screening structure includes a grate groove 16, a first square grate groove 20 and a second square grate groove 21. The grate groove 16 is located inside the bottom grate plate 15, and the second square grate groove 21 and the first square grate groove 20 are located inside the top grate plate 10; as shown Figure 1 , Figure 3 and Figure 4 As shown, the top grate plate 10 and the bottom grate plate 15 are both arc-shaped, and a plurality of No. 2 square grate grooves 21 and No. 1 square grate grooves 20 are arranged side by side inside the top grate plate 10, and a plurality of grate grooves 16 are arranged in a surrounding manner inside the bottom grate plate 15; Figure 5 As shown, the resistance box 22 is a square ring-shaped block, and four trapezoidal grooves are opened inside it, and different springs 23 are fixedly connected inside it; Figure 2 and Figure 5 As shown, four trapezoidal boxes 12 are arranged inside the blocking box 11, and a polygonal ring plate is welded at the bottom of the four trapezoidal boxes 12, and a square through cavity is formed between the hypotenuses. The size of the four trapezoidal boxes 12 is smaller than the four trapezoidal grooves, and the trapezoidal boxes are clamped in the trapezoidal grooves. The other end of the spring 23 is fixedly connected to the inner wall surface of the trapezoidal box 12, and the blocking box 11 and the resistance box 22 are elastically connected by the spring 23; Figure 3 and Figure 4 As shown, the shape and size of square grate groove No. 1 20 and square grate groove No. 2 21 are the same, and the four sides above are set as curved surfaces for making the material slide down, square grate groove No. 2 21 is horizontally distributed, and square grate groove No. 1 20 is vertically distributed, and grate groove 16 is an arc-shaped annular hole, and the size of its interior is larger than square grate groove No. 1 20 and square grate groove No. 2 21.

[0028] The working principle is as follows. When the material is crushed and enters the top grate plate 10, since the corners above the No. 1 square grate groove 20 and the No. 2 square grate groove 21 are curved surfaces, the material can slide through the No. 1 square grate groove 20 and the No. 2 square grate groove 21 through an arc. Since the No. 1 square grate groove 20 and the No. 2 square grate groove 21 are in different directions, they can adapt to materials falling in different directions or angles. At this time, due to the downward pressure of the material, it contacts the top grate plate 10, causing gravity to it, and the resistance box 22 at the bottom thereof will be squeezed by the elastic force of the spring 23. At the same time, the material enters the bottom grate plate 15, and then the top grate plate 10 and the bottom grate plate 15 are driven to vibrate by the spring after receiving the elastic force, thereby driving the stagnant material inside to vibrate. In this process, the material is Since the trapezoidal box 12 can be completely engaged with the resistance box 22, there will be no gap between the two. Not only can a closed environment for vibrating the material be ensured, but also leakage of the material can be prevented, and then the material is discharged through the grate groove 16. Since the corners above the No. 1 square grate groove 20 and the No. 2 square grate groove 21 are curved surfaces, and the grate groove 16 is arc-shaped, the material will not stagnate when passing through the top grate plate 10 and the bottom grate plate 15, but will slide down smoothly due to the curvature of its surface; in addition, the spring 23 is used as a buffer structure in the vibration structure, and the gravity of the material itself can be used to control the extrusion of the trapezoidal box 12 and the resistance box 22, so that the elastic force of the spring 23 can be used to vibrate the material, so as to control the discharge speed by vibration to avoid stagnation and blockage.

[0029] like Figure 2 and Figure 3 As shown, the four corners of the bottom grate plate 15 are welded with different corner blocks, the width of the four corner blocks is less than or equal to the width of the square through cavity, the corner blocks are clamped in the square through cavity, and form a blocking box 11 with four trapezoidal boxes 12, a clamping block 14 is arranged on the inner wall surface of the trapezoidal box 12, and a bayonet 17 is opened on one side of the bottom grate plate 15, the shape of the clamping block 14 is similar to the bayonet 17, and the clamping block 14 is clamped in the bayonet 17; Figure 1 and Figure 4 As shown, different connecting plates 18 are fixedly connected to both sides of the top grate plate 10, and a plurality of connecting holes 13 for connecting bolts are provided inside the two connecting plates 18. Different slide grooves 19 for clamping and fixing the top grate plate 10 are provided on both sides, and the two slide grooves 19 are respectively located directly below the two connecting plates 18.

[0030] The working principle is as follows. Due to the connecting holes 13 on the connecting plate 18, it can be fixed by connecting multiple bolts. In addition, due to the existence of the slide groove 19, the top grate plate 10 can be fixed by connecting a sliding block of the same shape, so as to effectively ensure that the vibration structure can realize the material output speed control based on a stable base point. In addition, there are two blocks 14, which are relatively arranged inside the blocking box 11, and the bayonet 17 is also arranged on both sides of the bottom grate plate 15. The block 14 is used to connect the bayonet 17, which not only facilitates disassembly but also stabilizes the bottom grate plate 15 and the blocking box 11, and the stability of the overall device. Of course, the number and position of the blocks 14 and the bayonet 17 here can be increased and changed as needed. Based on the stability, the change in number and position does not affect the operation of the device, and the top grate plate 10 and the bottom grate plate 15 are arc-shaped. When the material slides down, the arc-shaped structure can be used to reduce the impact force, so that the grate plate can be prevented from being damaged by impact.

[0031] A hammer crusher comprises all the above-mentioned anti-blocking grate plate assemblies. By arranging the above-mentioned anti-blocking grate plate assemblies, the device can have the characteristics of smoother material discharge and anti-blocking.
