Description

Technical Field

[0001] This utility model relates to a crushing toothed plate, and more particularly to a crushing toothed plate with a material guiding function. Background Technology

[0002] Jaw crushers are an essential piece of equipment in coarse crushing of ore. They use crushing teeth to tear and compress large pieces of material, breaking them into smaller particles to meet the particle size requirements of the production process.

[0003] Currently, most jaw crusher teeth on the market use equally spaced strip-shaped protrusions to achieve crushing. For example, patent application number CN201420527905.X discloses a jaw crusher tooth plate, which includes a tooth plate body. The upper surface of the tooth plate body is provided with uniformly arranged crushing teeth. In addition, most of the teeth are straight teeth and are equally spaced.

[0004] Equally spaced racks do not have the function of guiding material to achieve segmented crushing during operation. That is, the racks at the feed end are set with a small gap. Large materials will be crushed by multiple racks at the feed end, which will make the crusher too overloaded. At the same time, large materials will stay at the feed end for a long time, affecting the crushing efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a crushing toothed plate with a material guiding function.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A crushing toothed plate with a material guiding function includes a toothed plate body, on which a toothed rack is provided. The toothed plate has a feed end and a discharge end. The toothed plate body is an isosceles trapezoid with its feed end being wider than its discharge end. A reference toothed rack extending along the length direction is provided in the middle of the plate. Symmetrical inclined toothed racks are provided on both sides of the reference toothed rack. The spacing between adjacent toothed racks at the discharge end is the same, and the spacing at the feed end increases stepwise from the middle to both sides.

[0008] Preferably, the feed end of the toothed plate body is provided with an inclined first guide surface.

[0009] Preferably, the feed end of each rack is provided with a first chamfer for guidance.

[0010] Preferably, the discharge end of the toothed plate body has an inclined second guide surface.

[0011] Preferably, the discharge end of each rack is provided with a second chamfer for guidance.

[0012] Compared with the prior art, the advantages of this utility model are as follows: This application sets the toothed plate body into a trapezoidal structure and sets the toothed rack into a structure with gradually changing gaps. This allows large materials to be slightly squeezed at the top after entering, causing their edge parts to be broken and their volume to decrease. After the volume decreases, the material gradually moves downward. During the downward process, the squeezing amplitude gradually increases as it goes down, which is beneficial to the crushing of materials and reduces the load on the equipment. In addition, guide surfaces are set at both ends for guiding materials, which is beneficial to the entry and exit of materials. Attached Figure Description

[0020] This embodiment mainly describes the title of the crushing toothed plate with material guiding function, as follows:

[0021] Crushing toothed plates with material guiding function, such as Figure 1-3As shown, the device includes a toothed plate body 10 with a toothed rack. The toothed plate has an inlet end and an outlet end. The toothed plate body 10 is an isosceles trapezoid with its inlet end wider than its outlet end. A reference toothed rack 101 extending along the length direction is provided in the middle of the body. Symmetrical inclined toothed racks 102 are provided on both sides of the reference toothed rack 101. The spacing between adjacent toothed racks at the outlet end is the same, and the spacing at the inlet end increases stepwise from the middle to both sides. This design sets the toothed plate body 10 into a trapezoidal structure and the toothed racks into a structure with gradually changing gaps. This allows large materials to be slightly squeezed at the top after entering, causing their edges to be broken and their volume to decrease. As the volume decreases, the material gradually moves downward. During the downward movement, the squeezing amplitude gradually increases, which is beneficial for material crushing and reduces the load on the equipment. In addition, guide surfaces are provided at both ends for guiding the material, which is beneficial for the material's entry and exit.

[0022] Preferably, the feed end of the toothed plate body 10 is provided with an inclined first guide surface 103. Preferably, the feed end of each rack is provided with a first chamfer 104 for guidance. Preferably, the discharge end of the toothed plate body 10 is provided with an inclined second guide surface 105. Preferably, the discharge end of each rack is provided with a second chamfer 106 for guidance. Both guide surfaces and two chamfers are used to guide the material during feeding and discharging, facilitating the material's entry and exit and preventing right-angle structures from obstructing the material.

[0023] The title provided above provides a detailed description of the present utility model. Specific examples have been used to illustrate the principles and implementation methods of the present utility model. The description of the above embodiments is only for the purpose of helping to understand the present utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to the present utility model without departing from the principles of the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
