Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically to an impact mill hammer tilt angle mounting structure. Background Technology

[0002] Currently, impact mills are widely used in the crushing and processing of materials such as ores and building materials. During the operation of an impact mill, the hammer is the key crushing component, and its installation form and shape directly affect the crushing effect. Traditional hammers mostly adopt a rectangular or trapezoidal design, with the edge of the hammer installed radially along the impact disc, resulting in low crushing efficiency and difficulty in meeting the demand for high-efficiency production in a short period of time.

[0003] Chinese utility model patent with prior art announcement number CN217663649U discloses an impact mill hammer mounting structure. The impact mill hammer is installed by a slider and a strip groove, which does not require screw tightening. It is easy to disassemble and maintain, which can greatly shorten the maintenance time. Although this structure can effectively save maintenance time, the structure adopts a traditional rectangular hammer design, which has low crushing efficiency. Therefore, there is a need for an impact mill hammer structure that can perform crushing work efficiently. Utility Model Content

[0004] The technical problem to be solved by this utility model is that traditional hammers are mostly rectangular or trapezoidal in design, with the edges of the hammers installed radially along the impact disc, resulting in low crushing efficiency and difficulty in meeting the demand for high-efficiency production in a short time.

[0005] This utility model is achieved through the following technical solution: an impact grinding hammer head tilt angle mounting structure, including an impact disk, the impact disk having two end faces and a circumferential sidewall between the two end faces, the circumferential sidewall having a mounting groove; a parallelogram hammer head, the parallelogram hammer head including a body and an outer chamfer of the hammer head disposed on the body; the parallelogram hammer head is mounted in the mounting groove on the impact disk through a connector, such that the outer chamfer of the hammer head protrudes from the circumferential sidewall of the impact disk; and the placement direction of the parallelogram hammer head does not coincide with the radial direction of the impact disk.

[0006] Traditional hammerheads are mostly rectangular or trapezoidal in design, with the edges of the hammerheads installed radially along the impact disc. This results in low crushing efficiency and makes it difficult to meet the needs of high-efficiency production in a short period of time. In this application, the inclined installation method of the impact disc and the parallelogram hammerheads ensures that the material contacts the surface of the parallelogram hammerheads at an angle in every direction. During crushing, the impact disc rotates counterclockwise at high speed under the drive of the drive assembly, which can effectively prevent material from accumulating on the surface of the hammerheads.

[0007] Furthermore, the mounting groove extends through one end face of the impact disc, and the connector secures the parallelogram hammer head along the axial direction of the impact disc.

[0008] Furthermore, the parallelogram hammer head body is provided with at least two fastening holes, and the connector includes a fastening connector and a contact connector. The fastening connector and the contact connector cooperate with different fastening holes to fasten the parallelogram hammer head.

[0009] Furthermore, the fastening connector is a connecting screw; the contact connector is a cylindrical pin.

[0010] Unlike the traditional setup with two connecting screws, the combination of connecting screws and cylindrical pins reduces assembly and disassembly time and improves convenience.

[0011] Furthermore, the mounting groove is provided with multiple circular arrays distributed on the circumferential sidewall of the impact disc. The mounting groove includes threaded holes and pin holes. The threaded holes and pin holes cooperate with fastening connectors and contact connectors respectively to fasten the parallelogram hammer head.

[0012] Furthermore, the fastening holes on the parallelogram hammer head body include connecting hole I and connecting hole II. The radial axes of connecting hole I and connecting hole II do not coincide, so that the edge of the parallelogram hammer head naturally forms an angle with the radial direction of the impact disc.

[0013] The inclined surface of the parallelogram hammer head and the impact disc can change the trajectory of the material, forming a circulation to improve the uniformity and crushing capacity of the crushing.

[0014] Furthermore, the outer chamfer of the hammerhead protrudes 5mm-10mm from the circumferential sidewall of the impact disc.

[0015] The extended portion of the hammerhead's outer tangent collidees with the material at multiple angles, producing a pre-crushing effect. Then, secondary crushing is carried out through the main hammer surface of the parallelogram hammerhead, improving crushing efficiency.

[0016] Furthermore, the body of the parallelogram hammer head has a parallelogram plate-like structure, and the angle between the long side and the short side of the parallelogram hammer head body is 50°-80°.

[0017] Furthermore, the parallelogram hammer body is also provided with an inner trapezoidal surface for assisting in crushing.

[0018] Furthermore, the impact plate has a mounting hole at its center for fixed installation.

[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. This utility model uses an inclined installation method of impact disc and multiple parallelogram hammers to make the material contact the surface of parallelogram hammers at an angle in every direction. During crushing, the impact disc rotates counterclockwise at high speed under the drive of the drive component, which can effectively prevent the material from accumulating on the surface of the hammers. 2. By setting the axis of connecting hole I and connecting hole II to not coincide, the side of the parallelogram hammer naturally forms an angle with the radial direction of the impact disc. During crushing, the inclined surface of the angle between the parallelogram hammer and the impact disc can change the movement trajectory of the material, forming a circulation to improve the uniformity and crushing capacity of the crushing. 3. This utility model, through the parallelogram structure of the parallelogram hammer head, can generate stronger shearing collision when in contact with materials during rotation, thereby improving the material crushing efficiency; when crushing relatively flexible materials, it can crush materials more effectively compared with traditional shapes.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explaining the utility model only and are not intended to limit the utility model. It should be noted that this utility model is already in the actual research and development stage.

[0023] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in this embodiment, an impact grinding hammer tilt angle mounting structure includes an impact disk 1, which has two end faces and a circumferential sidewall between the two end faces, with a mounting groove formed on the circumferential sidewall; a parallelogram hammer 2, which includes a body and an external tangent angle 22 disposed on the body; the parallelogram hammer 2 is mounted in the mounting groove on the impact disk 1 through a connector, such that the external tangent angle 22 protrudes from the circumferential sidewall of the impact disk 1; and the placement direction of the parallelogram hammer 2 does not coincide with the radial direction of the impact disk 1.

[0024] The impact disc 1 has upper and lower surfaces. The upper surface of the impact disc 1 is detachably equipped with multiple parallelogram hammers 2 (the number is determined according to requirements) via connectors. The parallelogram hammers 2 are arranged in a circular array along the circumference of the impact disc 1. The impact disc 1 includes multiple threaded holes 11 and pin holes 12 (the number is the same as the number of parallelogram hammers 2) arranged in a circular array along the center of the impact disc 1. The threaded holes 11 and pin holes 12 are on the same radial line. The threaded holes 11 are threaded to engage with the connectors to secure the parallelogram hammers 2 to the impact disc 1. The impact disc 1 also includes a centrally located mounting hole 13 for fixing the impact disc 1 and the drive assembly (not shown in the diagram). The number of connectors is the same as the number of parallelogram hammers 2. The number of components is consistent, and the connecting parts include fastening connectors and contact connectors. The fastening connectors are connecting screws 3, and the contact connectors are cylindrical pins 4. The connecting screws 3 and cylindrical pins 4 cooperate to completely fix the impact disc 1 and the parallelogram hammers 2. Unlike the traditional setting of two connecting screws 3, the setting of connecting screws 3 and cylindrical pins 4 can reduce disassembly and assembly time and improve convenience. At the same time, the inclined installation method of the impact disc 1 and multiple parallelogram hammers 2 makes the material contact with the surface of the parallelogram hammers 2 at an angle in every direction. During crushing, the impact disc 1 rotates counterclockwise at high speed under the drive of the drive component, which can effectively prevent the material from accumulating on the surface of the hammers (the rotation direction of the impact disc 1 is limited to counterclockwise rotation).

[0025] Example 2 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the parallelogram hammer head 2 includes a body and an inner trapezoidal surface 21 and an outer chamfer 22 disposed on the body. The inner trapezoidal surface 21 is used to assist in crushing. The body of the parallelogram hammer head 2 is also provided with a connecting hole I 23 and a connecting hole II 24. The radial axes of the connecting holes I 23 and II 24 do not coincide. The connecting holes I 23 and II 24 are respectively connected to the connecting screw 3 and the cylindrical pin 4. Because the axes of the connecting holes I 23 and II 24 do not coincide, the edge of the parallelogram hammer head 2 naturally forms an angle with the radial direction of the impact disc 1 (e.g., ...). Figure 2 As shown in the figure), during crushing operation, the impact disc 1 rotates counterclockwise under the drive of the drive component. The inclined surface of the parallelogram hammer 2 and the impact disc 1 can change the movement trajectory of the material, forming a circulation to improve the uniformity and crushing capacity of the crushing.

[0026] The angle between the parallelogram hammer 2 and the impact disc 1 is set so that the outer tangent angle 22 of the hammer extends beyond the outer edge of the impact disc 1 by 5mm-10mm (parallelogram hammers 2 with different radial distances from the axis of the connecting hole I 23 and the connecting hole II 24 can be used to change the size of the angle between the parallelogram hammer 2 and the impact disc 1, thereby changing the size of the extension distance of the outer tangent angle 22). During crushing, the impact disc 1 rotates counterclockwise under the drive of the drive component, and the extended part of the outer tangent angle 22 of the hammer collides with the material at multiple angles, producing a pre-crushing effect. Then, secondary crushing is carried out through the main hammer surface of the parallelogram hammer 2, improving the crushing efficiency.

[0027] The parallelogram hammer 2 has a parallelogram structure, with two sets of opposite sides that are parallel and the angle between the long and short sides is 50°-80° (the angle between the long and short sides can be different depending on the hardness of the material to be crushed, and the size of the angle is proportional to the hardness). The parallelogram structure of the parallelogram hammer 2 makes the parallelogram hammer 2 generate stronger shearing collision when it comes into contact with the material during rotation, thus improving the material crushing efficiency. When crushing more flexible materials, it can crush the material more effectively than traditional shapes.

[0028] Example 3 Unlike the above embodiments, in this embodiment, the fastening connector can also be a fixed connector such as a weld, and the contact connector can also be a movable connector such as a connecting ring.

[0029] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
