Description

Technical Field

[0001] This application relates to the field of mechanical engineering technology, specifically to a crusher. Background Technology

[0002] Currently, crushers can be widely used in fields such as agricultural feed processing, industrial waste recycling, and pharmaceutical raw material processing to crush various blocky and fibrous materials into uniform particle sizes.

[0003] Existing crushers typically have overcurrent protection and power failure protection functions. Overcurrent protection monitors changes in current in the circuit and automatically cuts off power when an abnormal current is detected to prevent the motor from burning out, thus ensuring equipment safety. Power failure protection is used to deal with sudden power outages. When power is unexpectedly interrupted, the machine will be locked in a stopped state. Even if power is restored, the equipment cannot start on its own and must be manually reset to start, thus preventing the risk of accidental start-up and ensuring operator safety.

[0004] However, in existing technologies, overcurrent protection and power failure protection functions are usually implemented by two independent hardware circuit systems. This results in a complex control system structure with numerous circuits, which not only increases manufacturing costs and failure rates but also brings inconvenience to subsequent maintenance and operation.

[0005] Therefore, there is room for further improvement in existing crushers. Utility Model Content

[0006] In view of this, and in response to the technical problem of the complex control system structure caused by the overcurrent protection and power failure protection functions being implemented by two independent hardware systems in the prior art, this application provides a crusher that integrates current detection and power on / off control functions into one unit by setting an integrated control unit, thereby simplifying the internal structure of the control system and improving the system's integration and reliability.

[0007] This application provides a shredder, including: a body, a shredding actuator, and an integrated control unit, wherein the shredding actuator and the integrated control unit are disposed inside the body, and the integrated control unit is connected to the shredding actuator; The integrated control unit includes a detection module and a control module, wherein the detection module is used to monitor the current of the crushing actuator; The control module is used to control the power supply and de-energization of the crushing actuator based on the detection information from the detection module.

[0008] Compared with existing technologies, the pulverizer provided in this application adopts an integrated control unit, which integrates overcurrent protection and power failure protection functions into one unit, replacing the two separate control systems in existing technologies. This significantly simplifies the internal wiring structure of the control system and improves integration and overall reliability. The integrated control unit is directly connected to the pulverizing actuator, enabling it to respond quickly and accurately to fault conditions such as abnormal current and power interruption, and execute power failure commands, greatly ensuring the safety of equipment and personnel. Furthermore, it improves maintenance efficiency and simplifies maintenance procedures.

[0009] Preferably, the upper part of the machine body is provided with a feed inlet, and the feed inlet is provided with a dust blocking mechanism to prevent flying dust from passing through the feed inlet.

[0010] In this embodiment, a dust-blocking mechanism is further provided on the feed inlet of the machine body. On the one hand, the dust-blocking mechanism can prevent the flying dust generated during material crushing from flying into the external environment through the feed inlet, thereby maintaining the cleanliness of the operating environment; on the other hand, it can also prevent items unrelated to the material from accidentally entering the crusher, and prevent operators from accidentally putting their elbows into the crusher during operation, thereby ensuring the safety of operators when using the equipment.

[0011] Preferably, the dust-blocking mechanism includes a dust-blocking plate, which is movably connected to the feed inlet; The dust baffle plate is also provided with a material passage slit, which is used for material to pass through.

[0012] In this embodiment, the dust-blocking mechanism adopts a dust-blocking plate. The dust-blocking plate has a simple structure and can greatly reduce costs. The dust-blocking plate is movably connected to the feed inlet, which makes it easy to replace. Furthermore, the dust-blocking plate is installed in a hinged manner, which makes the operation of opening and closing the dust-blocking plate simple and convenient. The dust-blocking plate is further provided with a material passage slit, which can make it easier for some small materials to pass through the feed inlet while performing the dust-blocking function. This structure cleverly takes into account the needs of continuous feeding and airtight dust prevention, and can effectively prevent foreign objects and personnel's hands from accidentally entering, significantly improving safety performance.

[0013] Preferably, the machine body is provided with a crushing chamber, and the bottom of the crushing chamber is provided with a discharge mechanism, which is used to discharge the crushed material in the crushing chamber.

[0014] In this embodiment, a discharge mechanism is provided at the bottom of the crushing chamber, which can effectively discharge the crushed material without tilting it to avoid accumulation.

[0015] Preferably, the discharge mechanism and the crushing chamber are an integral structure, and the discharge mechanism includes a guide slope; The guide ramp is located at the discharge port of the crushing chamber and is used to discharge the crushed material.

[0016] In this embodiment, the inclined guide slope at the discharge port enables automatic and smooth discharge of the crushed material using its own gravity, effectively preventing blockages and residues during the discharge process, thus significantly improving discharge efficiency and continuity. This structure requires no additional power, simplifying the overall machine structure, reducing manufacturing costs and energy consumption, and also facilitating equipment cleaning and maintenance. Furthermore, the integrated structure of the discharge mechanism and the crushing chamber saves on manufacturing costs and ensures the overall stability of the crusher during operation.

The discharge mechanism includes a discharge hopper that is detachably connected to the bottom of the crushing chamber. The inner wall of the discharge hopper is provided with a smooth transition guide surface. A sealing element is provided at the connection between the discharge hopper and the crushing chamber.

[0018] In this embodiment, the split-type discharge mechanism, with its detachable discharge hopper design, greatly improves the ease of equipment maintenance. Its smooth internal guide surface ensures smooth material flow without residue, while the seals at the connection points effectively prevent dust leakage, ensuring a clean production environment and the purity of the materials.

[0019] Preferably, the grinding chamber is provided with a heat dissipation mechanism, which is used to conduct the heat generated inside the grinding chamber to the external environment.

[0020] In this embodiment, the heat dissipation mechanism effectively controls the working temperature of the crushing chamber by conducting internal heat to the outside, preventing changes in material properties due to high temperatures and extending the service life of the equipment.

[0021] Preferably, the heat dissipation mechanism includes heat dissipation holes, which are formed on both sides of the cavity wall of the body. The heat dissipation holes are strip-shaped holes, and there are multiple strip-shaped holes. The plurality of strip-shaped holes extend vertically along the cavity wall of the machine body, and the plurality of strip-shaped holes are arranged at intervals.

[0022] In this embodiment, the heat dissipation mechanism is selected by opening multiple strip-shaped heat dissipation holes on both sides of the cavity wall of the machine body, forming an efficient convection air duct, which significantly improves the heat dissipation efficiency. At the same time, the strip structure can effectively prevent large foreign objects from entering.

[0023] Preferably, it also includes a support component, which includes a support portion and a movable portion; The support part is connected to the body and is used to support the body; The movable part is located at the end of the support part away from the body, and the movable part is used to drive the body to move.

[0029] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0030] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0031] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0032] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 7 illustrate.

[0033] This application provides a pulverizer, which includes a body 1, a pulverizing actuator 2, and an integrated control unit 3, such as... Figures 1 to 3 As shown, the crushing actuator 2 and the integrated control unit are both located inside the machine body 1 for crushing the input materials. A crushing chamber 12 is formed inside the machine body 1, in which the crushing actuator 2 is installed in the middle. The integrated control unit 3 is located close to the crushing actuator 2 and is electrically connected to the crushing actuator 2 via wires. The integrated control unit 3 is located at the bottom of the machine body 1. The integrated control unit 3 monitors the operating current of the crushing actuator 2 in real time and controls the energization and de-energization of the crushing actuator 2 according to the current signal. If the integrated control unit 3 detects an abnormal current in the crushing actuator 2 during actual operation, it will immediately cut off the power supply to prevent equipment failure, thereby achieving overcurrent protection. After the abnormality is eliminated, the integrated control unit 3 will control the equipment to restart to restore normal operation of the equipment.

[0034] This application replaces the two independent systems controlled by the traditional distributed overcurrent switch and electromagnetic switch with an integrated control unit 3. This not only saves on component installation space and subsequent maintenance costs, but also simplifies the operation process: it can quickly respond and stop the machine when an overload fault occurs, and there is no need to reset the switches one by one after the fault is cleared. This avoids cumbersome operation and reduces the risk of equipment accidental start-up due to misoperation, significantly improving work efficiency and safety. At the same time, the integrated control unit 3 is located inside the machine body 1. The closed environment inside the machine body 1 can provide physical protection for the integrated control unit 3, effectively isolating it from dust and material debris generated during the crushing operation, as well as water stains and impacts from the external environment, reducing the risk of short circuits, leakage and component damage. It also reduces external wiring, making the equipment structure more compact and adaptable to the layout requirements of narrow working scenarios such as workshops.

[0035] Furthermore, such as Figure 4 , Figure 5 As shown, the upper part of the machine body 1 is provided with a feed inlet 11, and a dust-blocking mechanism is provided at the opening of the feed inlet 11. The dust-blocking mechanism includes a dust-blocking plate 4, one side of which is hinged to the edge of the feed inlet 11, and the other side is detachably fixed to the feed inlet 11 by a buckle. The relative angle between the dust-blocking plate 4 and the feed inlet 11 can be adjusted by flipping the dust-blocking plate 4 to adapt to different feeding requirements. Multiple strip-shaped material passage slits 41 are evenly distributed on the dust-blocking plate 4. The width of the material passage slits 41 is adapted to the particle size of common materials, which can allow materials to pass smoothly into the crushing chamber 12, while preventing dust splashed during the crushing process from overflowing from the feed inlet 11. When it is necessary to process oversized materials, the buckle can be released to flip the dust-blocking plate 4 open, flexibly adapting to different feeding requirements.

[0036] The crushing chamber 12 inside the machine body 1 is a hollow cavity. The bottom of the crushing chamber 12 is equipped with a discharge mechanism, which can effectively discharge the crushed material without tilting to avoid accumulation.

[0037] like Figure 5 As shown, in an optional embodiment of this application, the discharge mechanism and the crushing chamber 12 are an integral structure, the main body of which is the guide slope 5. The guide slope 5 extends downward in a direction away from the center of the crushing chamber 12. The crushed material can slide out naturally along the slope under the action of gravity without the need for additional driving components, thus avoiding the accumulation and blockage of the material at the bottom of the chamber.

[0038] In another optional embodiment of this application, the discharge mechanism and the crushing chamber 12 are connected separately. The discharge mechanism includes a discharge hopper that is detachably connected to the bottom of the crushing chamber. The detachable connection greatly improves the ease of maintenance of the equipment. The inner wall of the discharge hopper is provided with a smooth transition guide surface. The smooth guide surface ensures smooth material flow and no residue.

[0039] Furthermore, a sealing element is provided at the connection between the discharge hopper and the crushing chamber, which effectively prevents dust leakage and ensures the cleanliness of the production environment and the purity of the materials.

[0040] like Figure 5 , Figure 6 As shown, a heat dissipation mechanism is also provided on the wall of the crushing chamber 12. The heat dissipation mechanism effectively controls the working temperature of the crushing chamber by conducting internal heat to the outside, avoiding changes in the properties of materials due to high temperature, and extending the service life of the equipment.

[0041] The heat dissipation mechanism includes multiple strip-shaped heat dissipation holes 6, which are set on the cavity walls on both sides of the body 1. The multiple strip-shaped heat dissipation holes 6 extend vertically along the cavity walls of the body 1 and are arranged at intervals to form an efficient convection air duct, which significantly improves the heat dissipation efficiency. At the same time, the strip structure can effectively prevent large foreign objects from entering. In addition, the elongated shape of the strip-shaped heat dissipation holes 6 reduces the impact on the strength of the cavity wall structure while ensuring the heat dissipation area.

[0042] like Figures 1 to 6 As shown, the bottom of the machine body 1 is provided with a support component 7, which is correspondingly set in the load-bearing area (such as the four corners or edges) of the bottom of the machine body to form a stable support. The support component 7 includes a support part and a moving part. The support part is an integrally formed L-shaped trolley frame 71. The upper end of the L-shaped trolley frame 71 is integrally provided with two upwardly extending and parallel sleeve posts 711. The bottom of the machine body 1 is provided with two mounting holes 13. The L-shaped trolley frame 71 is inserted into the mounting holes 13 through the sleeve posts 711 and connected to the machine body 1. The moving part is two rollers 73. The wheel axle 72 is fixedly installed at the lower end of the L-shaped trolley frame 71, and the two rollers 73 are rotatably installed at both ends of the wheel axle 72. The one-piece molded L-shaped trolley frame 71 is highly rigid and can evenly transmit the weight of the machine body 1 to the rollers 73, ensuring that the equipment is stable and does not shake during crushing operations. The design of the L-shaped trolley frame 71 can save space, making it easy to store the crusher. The design of the connecting column 711 and the mounting hole 13 can facilitate the installation and disassembly of the L-shaped trolley frame 71 and the machine body 1. The design of the rollers 73 makes the movement of the crusher effortless, and the position can be adjusted without external handling tools, adapting to the layout requirements of different work sites.

[0043] In this embodiment, the working process of the crusher is as follows: The operator adjusts the angle of the dust baffle 4 according to the particle size of the material, and puts the material into the feed inlet 11. The integrated control unit 3 starts the crushing execution mechanism 2 to start the crushing operation. During the crushing process, the heat dissipation mechanism continuously exhausts the heat in the cavity, and the crushed material is naturally discharged along the guide slope 5. If an overload occurs, the integrated control unit 3 immediately cuts off the power and alarms. After the fault is cleared, the equipment can be restarted by pressing the control button of the integrated control unit 3. When it is necessary to change the working position, the machine body 1 can be moved by pushing the rollers 722 of the support component 7.

[0044] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
