Description

Technical Field

[0001] This utility model relates to the technical field of crushers, and in particular to a high-efficiency composite crusher. Background Technology

[0002] A crusher is an important piece of industrial machinery used to break large materials into smaller pieces for subsequent processing, transportation, and use. In the mining industry, crushers are used to crush mined ore, providing suitable materials for subsequent mineral processing and smelting. In the construction industry, crushers are used to process construction waste and waste concrete, converting them into recycled aggregates and realizing resource recycling. In the metallurgical industry, crushers are used to process various metallic and non-metallic ores, providing the raw materials needed for smelting and processing. In many industrial sectors, crushers are indispensable key equipment, their function being to crush large materials into small particles that meet the requirements of subsequent processing or use. With the rapid development of industry, the performance requirements for crushers are also increasing, requiring not only high-efficiency crushing capacity but also ensuring the stability of equipment operation and the precision of crushed materials.

[0003] Currently, the traditional compound crusher is used to crush small pieces of material into even smaller particles. The small pieces of material are directly poured into the feed inlet and then concentrated into the crushing zone for crushing.

[0004] The above-mentioned existing technical solutions have the following defects: the material cannot be evenly distributed at the feed inlet, resulting in serious material accumulation. This not only reduces the crushing efficiency and prevents some materials from being fully crushed, but may also cause blockage inside the crusher, hindering the normal flow of materials and overloading the pulley, thereby damaging the drive equipment and affecting the continuity of the entire production process. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency composite crusher to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A high-efficiency compound crusher, comprising:

[0008] support;

[0009] A sleeve, the bottom of which is open, a counter-attack plate is bolted to the inner wall of the sleeve, a feed funnel is connected to the top of the sleeve, the sleeve is set at the top of the support, and a shaft is set inside the sleeve.

[0010] A material feeding disc module, wherein the material feeding disc module is located at the inner top end of a sleeve, and the material feeding disc module is sleeved on the top end of a shaft, and the material feeding disc module is used to control the distribution of materials;

[0011] A crushing device, wherein multiple crushing devices are provided, and the multiple crushing devices are equally spaced from top to bottom on the bottom end of the shaft, and the multiple crushing devices are used for multi-stage crushing of materials;

[0012] The sleeve is rotatably mounted on the top of the sleeve. The top end of the shaft passes through the top of the sleeve and extends to the outside of the sleeve. The top end of the shaft is fitted with a driven pulley located outside the sleeve. The pulley is connected to the driven pulley via a transmission belt. A drive motor is provided on the top of the sleeve, which is used to drive the pulley to rotate circumferentially.

[0013] By adopting the above technical solution, the servo motor drives the throwing disc module and the crushing device to rotate at high speed. The material enters the throwing disc module at the top of the sleeve through the feed funnel. Under the action of centrifugal force, the material flies out from the throwing disc module, so that the material is evenly distributed around the crushing device. This prevents unsorted material from directly entering the crushing device, which would cause material accumulation, blockage inside the sleeve, or overload of the pulley. The flying material collides with the impact plate on the inner wall of the sleeve, which can improve the crushing efficiency. The setting of multiple crushing devices can make the material receive impact forces of different directions and sizes during the crushing process, which is conducive to crushing the material into more uniform particles, improving the finished product precision, and achieving the goals of protecting the equipment and improving the quality and efficiency of material crushing.

[0014] In a further embodiment, a bearing seat is fixedly connected to the bottom end of the shaft, and the bottom of the sleeve gradually tapers from top to bottom.

[0015] By adopting the above technical solution, the bottom of the sleeve gradually contracts to form a funnel-like shape. After the crushing operation is completed, the material crushed into small particles will converge towards the concave center along the inner wall of the gradually contracting bottom of the sleeve, so that the material can be discharged from the bottom of the sleeve more smoothly and in a concentrated manner.

[0016] In a further embodiment, the material-spinning tray module includes:

[0017] A disc, wherein a first through hole is provided at the center of the top of the disc, and the first through hole is fixedly connected to the outer wall of the shaft;

[0018] The disc includes multiple ear plates, which are evenly spaced around the top of the disc.

[0019] By adopting the above technical solution, when the material arrives at the throwing disc module through the feed hopper, the multiple ear plates can play a temporary blocking role, preventing the material from entering the crushing device below the throwing disc module in a concentrated manner, which could easily cause blockage of the crushing device or even damage to the crusher. Under the action of the strong centrifugal force generated by the high-speed rotation of the throwing disc module, the material will be thrown out from the gap between the two adjacent ear plates and fall evenly around the crushing device. The thrown material will also collide strongly with the impact plate on the inner wall of the sleeve, which is conducive to improving the working efficiency of subsequent crushing.

[0020] In a further embodiment, the crushing device includes:

[0021] The first circular plate is spaced apart at the bottom end of the disk;

[0022] The second circular plate is spaced apart at the bottom end of the first circular plate. The diameters of the first and second circular plates are the same. The first and second circular plates are coaxially aligned. A second through hole is formed at the center of the first and second circular plates. The second through hole is fixedly connected to the outer wall of the shaft. Multiple eccentric first threaded holes are provided at the top of the first and second circular plates.

[0023] The breaker is provided with multiple breaker hammers. Each breaker hammer includes an integrally formed hammer head and hammer handle. The top end of the hammer handle away from the hammer head is provided with multiple through-hole second threaded holes. The first threaded holes and the second threaded holes are coaxially aligned. The multiple hammer handles are screwed into the gap between the first circular plate and the second circular plate through the first threaded holes and the second threaded holes.

[0024] By adopting the above technical solution, the breaker hammer is screwed to the first circular plate and the second circular plate. When a breaker hammer is worn or damaged, it can be replaced individually without replacing the entire crushing device, thus reducing the maintenance cost and time of the crusher.

[0025] In a further embodiment, the inner diameter of the bottom end of the sleeve extends around a plurality of support rods toward the bottom end of the bearing housing, the plurality of support rods being used to support the bottom end of the bearing housing.

[0026] By adopting the above technical solution, the bearing housing bears the transmission force of the shaft, the throwing disc module and the crushing device, so that the shaft can smoothly drive the throwing disc module and the crushing device to rotate. Moreover, multiple support rods can limit the radial and axial sway of the bearing housing, so that it is always in a stable position and avoids the normal operation of the crusher due to deviation.

[0027] In a further embodiment, a torque sensor is fixedly connected to the bottom end of the shaft hole of the driven pulley, and the other end of the torque sensor is fixedly connected to the top end of the shaft. The torque sensor is used to detect the torque of the driven pulley in real time.

[0028] By adopting the above technical solution, the torque sensor can detect the torque of the pulley in real time and promptly detect abnormal torque fluctuations. When the torque suddenly increases and does not decrease, it indicates that the material is stuck in the sleeve, causing the rotational load of the shaft to increase. When the torque gradually decreases, it indicates that the components of the crushing device may be loose or worn. It can detect the fault of the crusher in advance and ensure the normal operation of the crushing operation.

[0029] In summary, this utility model has the following beneficial effects:

[0030] 1. By setting a throwing disc module at the top of the inside of the sleeve, when the material enters the sleeve through the feed funnel, the throwing disc module rotates at high speed under the drive of the drive motor. It uses centrifugal force to make the material evenly distributed around the crushing device, which effectively avoids the problems of material accumulation and blockage inside the sleeve. It also reduces the risk of overload of the drive motor and protects the crusher. In addition, the material collides with the impact plate on the inner wall of the sleeve during the flying process, which further enhances the crushing effect and improves the crushing efficiency.

[0031] 2. By setting up multiple crushing devices, the number of collisions and frictions of materials during the crushing process can be increased, thereby improving the precision of the finished product and meeting the strict requirements of different industrial fields for material particle size, thus achieving the effect of improving crushing precision;

[0032] 3. By using a bolted connection between the breaker hammer and the first and second circular plates, when a breaker hammer is worn or damaged, it can be replaced individually without replacing the entire crushing device, which can reduce the maintenance cost and time of the crusher.

Extending to the outside of sleeve 2, the top of shaft 7 is fitted with a driven pulley 9 located outside sleeve 2. Pulley 6 is connected to driven pulley 9 via a transmission belt. A drive motor 10 is installed at the top of sleeve 2, which drives pulley 6 to rotate circumferentially. A bearing seat is fixedly connected to the bottom of shaft 7. The bottom of sleeve 2 gradually tapers from top to bottom. Four support rods extend from the circumference of the inner diameter of the bottom of sleeve 2 toward the bottom of bearing seat. The four support rods support the bottom of bearing seat. A torque sensor is fixedly connected to the bottom of shaft hole of driven pulley 9. The other end of torque sensor is fixedly connected to the top of shaft 7. Torque sensor is used to detect the torque of driven pulley 9 in real time.

[0042] like Figure 3 As shown, the material throwing disc module 4 includes: a disc 41, with a first through hole extending vertically through the center of the top of the disc 41, the first through hole being fixedly connected to the outer wall of the shaft 7; and ear plates 42, four ear plates 42 being provided, the four ear plates 42 being equally spaced around the top of the disc 41; the crushing device 5 includes: a first circular plate 51, the first circular plates 51 being spaced apart at the bottom of the disc 41; and a second circular plate 52, the second circular plates 52 being spaced apart at the bottom of the first circular plate 51, the diameters of the first circular plate 51 and the second circular plate 52 being the same, the first circular plate 51 and the second circular plate 52 being coaxially aligned, the first circular plate 51 and the second circular plate 52 being... A second through hole is formed at the center of a circular plate 51 and a second circular plate 52, which is fixedly connected to the outer wall of the shaft 7. The top of the first circular plate 51 and the second circular plate 52 is provided with a plurality of eccentric first threaded holes. And a breaker hammer 53, of which four breaker hammers are provided. The breaker hammer 53 includes an integrally formed hammer head and a hammer handle.

[0043] Specific implementation process: First, the operator feeds the material to be crushed into the sleeve 2 through the feed funnel 3. After entering the sleeve 2, the material falls directly onto the throwing disc module 4 located at the top of the sleeve 2. At this time, the drive motor 10 drives the pulley 6 to start rotating. The pulley 6 drives the driven pulley 9 to start rotating through the transmission belt. Since the top of the shaft 7 is connected to the driven pulley 9, the shaft 7 rotates at high speed, thereby driving the throwing disc module 4 to rotate synchronously at high speed. Because the disc 41 of the throwing disc module 4 has four ear plates 42 evenly spaced around its perimeter, the material is subjected to a strong centrifugal force on the disc 41 and flies out quickly from the gap between the two adjacent ear plates 42, evenly scattering around the crushing device 5 at the bottom of the sleeve 2. The uniform distribution effectively avoids material accumulation and ensures smooth crushing operations. At the same time, the five staggered crushing devices 5 rotate at high speed under the drive of the shaft 7. Four crushing hammers 53 are screwed onto the first circular plate 51 and the second circular plate 52 in the crushing device 5. As the circular plates rotate, the crushing hammers 53 repeatedly impact and crush the scattered materials. During the collision with the crushing hammers 53 and the impact with the impact plate 8 on the inner wall of the sleeve 2, the materials are gradually crushed into particles that meet the requirements. During the crushing operation, the torque sensor between the driven pulley 9 and the shaft 7 detects the torque of the driven pulley 9 in real time. The operator can understand the operating status of the equipment in a timely manner based on the torque data, ensuring that the crushing operation is carried out efficiently and stably.
