Description

Technical Field

[0001] The present application relates to the field of crushing technology, and in particular to a crusher distribution plate. Background Art

[0002] Taking the cone crusher as an example, the material is not allowed to enter the crushing chamber directly, because if the falling material cannot be evenly distributed along the circumference of the crushing chamber, it will cause uneven force on the crushing chamber, which will cause serious damage to the equipment. A distribution plate is usually set above the crushing chamber. When the feeding equipment feeds, the material first falls on the distribution plate. The distribution plate rotates, and the material is thrown out under the action of centrifugal force and scattered around the crushing chamber.

[0003] At present, the material distribution plate is basically designed as a circular material distribution plate, with a high outer edge and a groove formed inside. The circular material distribution plate feeds more evenly under the action of centrifugal force, and there is usually material accumulation in the groove, which prevents the material from directly impacting the middle part of the material distribution plate when the crusher is working, delaying its wear and extending its life. However, with the wear along the edge, the material accumulation in the groove becomes less and less, and the material drop part in the middle of the material distribution plate will wear faster after losing protection. Summary of the invention

[0007] Optionally, in the orthographic projection along the length direction of the strip-shaped convex surface, the contour line of the strip-shaped convex surface is an arc line.

[0008] Optionally, the material distribution tray includes a bottom surface opposite to the top surface, and the top surface includes a first top surface located on one side of the strip convex surface, and the distance between the first top surface and the bottom surface gradually decreases in the direction from the strip convex surface to the edge of the material distribution tray.

[0020] Please refer to Figure 1 , Figure 1 It is a schematic diagram of a crusher distribution plate 100 showing an exemplary embodiment of the present application.

[0021] The present application provides a crusher distribution disc 100 (hereinafter referred to as the distribution disc 100), the distribution disc 100 includes a top surface 10, the middle part of the top surface 10 is formed with a strip convex surface 11 protruding upward, the strip convex surface 11 extends from one end of the distribution disc 100 to the other end, and the strip convex surface 11 is set as the material receiving surface when the material is sprinkled into the distribution disc 100. According to the above description, the thickness of the distribution disc 100 is relatively thick at the strip convex surface 11, and the material sprinkled into the distribution disc 100 will impact the distribution disc 100. By setting the material receiving surface at the thicker strip convex surface 11, it can withstand the impact for a long time, and the wear resistance effect is better. In addition, while the material slides down to both sides of the low position, it will be evenly scattered around under the action of centrifugal force, ensuring the uniformity of feeding and the uniformity of the discharging particle size, which not only improves the production capacity but also reduces the consumption of wearing parts.

[0022] In a specific embodiment, the thickness of the material distribution plate 100 at the strip convex surface 11 can be set to 6-7 cm, and the thickness at the edge of the material distribution plate 100 can be set to be more than 4 cm.

[0023] Optionally, the material distribution plate 100 can be made of high manganese steel containing 10% to 15% manganese and 0.90% to 1.50% carbon, which has high hardness and great brittleness. The most important feature of high manganese steel is that under strong impact and extrusion conditions, the surface layer can quickly undergo work hardening, so that the core still maintains the good toughness and plasticity of austenite while the hardened layer has good wear resistance. In addition, the material distribution plate 100 can use the old liner replaced by the ball mill to realize the utilization of waste materials. Not only does it meet the requirements of the middle protrusion and low sides and wear resistance in terms of thickness, it is also easy to process and saves costs.

[0024] Please refer to Figure 2 , Figure 2 for Figure 1 A perspective view of a distribution tray 100 is shown in FIG.

[0025] The material distribution plate 100 is used to be connected to the main shaft 200, and the main shaft 200 drives the material distribution plate 100 to rotate. The rotation of the main shaft 200 can cause the materials sprinkled on the strip convex surface 11 to be thrown out under the action of centrifugal force and enter the crushing chamber. The material distribution plate 100 can be bolted to the main shaft 200. In addition, the powder plate 100 and the main shaft 200 can be partially welded at the joint to increase the firmness of the connection between the two.

[0026] In one embodiment, in the orthographic projection along the length direction of the strip convex surface 11, the contour line of the strip convex surface 11 is an arc line with a high middle and low ends. In other words, the thickness dimension in the middle of the strip convex surface 11 is greater than the thickness dimensions on both sides, which is more conducive to improving the wear resistance of the strip convex surface 11. Of course, in some other embodiments, the strip convex surface 11 can be set as a plane.

[0027] In one embodiment, the material distribution plate 100 includes a bottom surface 20 opposite to the top surface 10, and the bottom surface 20 is a plane. The top surface 10 includes a first top surface 12 located on one side of the strip convex surface 11, and a first top surface 12 is formed in a direction from the strip convex surface 11 to the edge of the material distribution plate 100 ( Figure 2 The distance between the first top surface 12 and the bottom surface 20 gradually decreases, so that the first top surface 12 is gradually lowered relative to the strip convex surface 11, thereby gradually reducing the thickness of the edge of the material distribution plate 100. Figure 2 In the illustrated embodiment, the first top surface 12 is configured as an arc-shaped surface for ease of processing.

[0028] In one embodiment, the top surface 10 further includes a second top surface 13 located on one side of the strip convex surface 11, the first top surface 12 and the second top surface 13 are located on two opposite sides of the strip convex surface 11, and the direction from the strip convex surface 11 to the edge of the material distribution plate 100 ( Figure 2In the S2 direction in FIG. 1 , the distance between the second top surface 13 and the bottom surface 20 gradually decreases. In this way, the second top surface 13 is gradually lowered relative to the strip convex surface 11, thereby gradually reducing the thickness of the other side edge of the material distribution plate 100. Figure 2 In the illustrated embodiment, the second top surface 13 is configured as an arc-shaped surface for ease of processing.

[0029] In one embodiment, the first top surface 12 and the second top surface 13 are symmetrically arranged on two opposite sides of the strip-shaped convex surface 11. That is, the first top surface 12 and the second top surface 13 have the same shape.

[0030] Please combine Figure 1 and Figure 3 , Figure 3 for Figure 1 Another perspective view of the distribution tray 100 is shown in FIG.

[0031] In one embodiment, the material distribution plate 100 further includes a mounting hole 110 provided on the strip convex surface 11, and the mounting hole 110 is configured as a stepped hole with a large top and a small bottom. The mounting hole 110 is used to insert a bolt to lock the material distribution plate 100 and the main shaft 200. The stepped hole can prevent the bolt from being exposed, thereby protecting the bolt and preventing excessive wear of the bolt under the impact of the material. In the process of sprinkling the material into the strip convex surface 11, a portion of the material may be stored in the stepped hole, and the portion of the material will not be thrown out even under the action of centrifugal force, but will remain in the mounting hole 110, so that the material can be prevented from repeatedly impacting the bolt, thereby protecting the bolt.

[0032] In one embodiment, in order to increase the amount of material stored in the mounting hole 110, the distance t2 between the step surface 1100 of the step hole and the bottom surface 20 can be set to be smaller than the distance t1 between the step surface 1100 and the top surface 10. In this way, the depth dimension of the large hole is greater than the depth dimension of the small hole, so that more material can be stored.

[0033] The material distribution plate 100 provided by the present application has extremely low manufacturing cost and is easy to obtain. It can be formed by using the replaced old liner of the expired ball mill. The material distribution plate 100 can be used for 9 months, and its service life is increased by 3 times, which reduces the spare parts cost, labor and maintenance cost.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
