Description

Technical Field

[0001] The present invention relates to the technical field of construction waste crushing, and more specifically, it relates to a waste crushing device for construction project management. Background Art

[0002] In the current field of construction project management, waste crushing equipment is a key link in the treatment of construction waste. With the continuous improvement of the requirements for environmental protection and resource recycling in the construction field, the treatment demand for various construction wastes is increasing day by day, including a large number of relatively soft but tough materials such as wood, plastic, rubber, etc. Due to their physical properties, such materials require the crushing equipment to provide a sufficiently high rotational speed during the crushing process in order to achieve effective cutting and tearing effects and realize ideal crushing particle size and treatment efficiency. However, the mainstream construction waste crushing equipment on the market at present generally adopts a direct hard connection power transmission method, that is, the motor is directly connected to the crushing tool or rotor through a rigid transmission device. Although this hard connection design is simple in structure and high in transmission efficiency in power transmission, it lacks necessary buffering and protection mechanisms, making the entire power system vulnerable when facing sudden changes in load and unable to adapt to the actual working environment where construction waste has complex components and uneven hardness.

[0003] In the actual process of construction waste treatment, due to uneven feeding or the presence of unexpected hard objects (such as metal components, concrete blocks, etc.), the crushing equipment often faces the risk of instantaneous jamming or stalling. In the hard connection transmission system, this sudden resistance will be directly transmitted to the motor, causing the power source to operate overloaded. When the rotor or tool is suddenly stuck, the motor will still try to maintain the rated speed output, resulting in a sudden increase in current, generating huge electromagnetic shock and mechanical stress. This will not only trigger the thermal protection device of the motor, but also accelerate the aging of the insulation layer of the motor winding and shorten the service life of the bearing, and may even cause the motor to burn out or the mechanical transmission components to break. This equipment damage caused by jamming not only increases the maintenance cost and downtime, but also may trigger safety accidents and pose a potential threat to the personnel at the construction site.

[0010] Preferably, a plurality of friction grooves corresponding to the friction rings are respectively opened on each synchronous block, a plurality of guide rods are installed on the outer wall of the output sleeve, a guide hole is opened on the synchronous block, and the guide rods are slidably connected in the guide hole.

[0011] Preferably, two push springs are respectively installed at the lower ends of each synchronous block, and the other ends of the plurality of push springs respectively abut against the outer wall of the output sleeve.

[0012] Preferably, the crushing mechanism further includes a plurality of crushing pieces, the plurality of crushing pieces are respectively installed on the driving shaft and the driven shaft in an alternating manner, synchronous wheels are installed on both the driving shaft and the driven shaft, and the two synchronous wheels are engaged with each other.

[0013] (III) Beneficial effects Compared with the prior art, the present invention provides a garbage crushing device for construction project management, which has the following beneficial effects: Traditional crushing devices generally use a hard connection method to directly transmit the motor power to the crushing component. However, this device introduces a composite transmission system composed of a counterweight wheel, an output sleeve, a follower wheel, etc. This connection behaves as a rigid transmission under normal working conditions, transmitting the high speed of the motor to the crushing component completely and efficiently to ensure sufficient crushing of flexible garbage. When encountering jamming or overload, the system can automatically switch to an elastic transmission, effectively protecting the motor and the transmission system from damage. This intelligent adjustment ability not only significantly improves the adaptability and reliability of the device, but also greatly extends the service life of the device, reducing the maintenance frequency and cost.

[0014] Secondly, through the combined action of the spring group and the friction force between the counterweight wheel and the output sleeve, precise torque control is achieved. During normal operation, the spring provides the basic pressure, and as the rotation speed increases, the friction force generated between the friction ring and the friction groove gradually increases, forming a "speed-adaptive" connection strength. This design enables the device to have a strong enough power transmission ability during high-speed operation, and can flexibly disengage from the hard connection state when encountering resistance. In particular, the uniform distribution design of multiple friction rings ensures the balanced distribution and stable transmission of the friction force, avoiding local stress concentration and improving the durability and reliability of the connection mechanism.

[0015] Thirdly, the contact mechanism between the roller and the raised block of this device provides the ability to judge and respond to overload. When encountering hard objects or impurities that are difficult to crush during the crushing process and causing the output sleeve to be blocked, the roller will immediately start to slide along the raised block. This design can not only quickly respond to load changes, but also ensure that the motor continues to operate without being forced to stop.

[0016] Fourthly, through the sliding connection between the guide hole on the synchronizing block and the guide rod, combined with the auxiliary thrust of the push spring, the system can automatically adjust the friction force according to the rotation speed. When the device is running at high speed, the centrifugal force pushes the synchronizing block to move outwards, increasing the contact pressure between the friction ring and the friction groove and providing a stronger power transmission ability. When the speed decreases or jamming occurs, the pressure decreases accordingly, facilitating the system to release the hard connection. This self-adjusting characteristic without external control.

[0017] In summary, this garbage crushing equipment for construction project management achieves a balance between efficient crushing and mechanical protection through its connection mechanism and torque control. It is particularly suitable for dealing with construction waste with complex compositions and uneven hardness. It not only solves the pain point that traditional equipment is prone to damage the motor due to jamming during the processing, but also improves the energy utilization efficiency through an intelligent torque transmission mechanism, reduces the risk of equipment damage and maintenance costs, and provides a safer, more efficient and reliable technical solution for the resource treatment of construction project waste.

A plurality of friction rings 28 are coaxially installed on the side wall of the counterweight wheel 21. A plurality of synchronous blocks 29 are attached to the side wall of the counterweight wheel 21. The connecting mechanism further includes a threaded rod 210 threadedly connected inside a plurality of protruding pipes 23. A spring 211 is installed on each pressure rod 24. The other end of the spring 211 is installed with a thrust bearing 212. The threaded rod 210 presses on the thrust bearing 212. A plurality of positioning bars 213 are equidistantly installed on the side wall of each pressure rod 24. A plurality of positioning grooves 214 are respectively formed inside each protruding pipe 23. The positioning bar 213 is slidably connected inside the positioning groove 214. A transmission shaft 215 is installed on the motor 12. An input wheel 216 is coaxially installed on the transmission shaft 215. An internal wheel 217 is coaxially installed inside the counterweight wheel 21. A plurality of connecting rods 218 are installed on the output sleeve 22. A limiting disc 219 is installed on the plurality of connecting rods 218. A follower wheel 220 is rotatably installed on each connecting rod 218. One end of the plurality of follower wheels 220 meshes with the internal wheel 217, and the other end of the plurality of follower wheels 220 meshes with the input wheel 216. Both ends of the input wheel 216 are respectively attached to the limiting disc 219 and the output sleeve 22. A plurality of friction grooves 221 corresponding to the friction rings 28 are respectively formed on each synchronous block 29. A plurality of guide rods 222 are installed on the outer wall of the output sleeve 22. A guide hole 223 is formed on the synchronous block 29. The guide rod 222 is slidably connected inside the guide hole 223. Two push springs 224 are respectively installed at the lower end of each synchronous block 29, and the other ends of the plurality of push springs 224 respectively abut against the outer wall of the output sleeve 22.

[0024] When crushing flexible garbage such as wood and plastic, a relatively high rotational speed needs to be provided. First, the motor 12 drives the rotation of the transmission shaft 215. Since the input wheel 216 is connected to the transmission shaft 215, it will drive the synchronous rotation of the input wheel 216. And the input wheel 216 meshes with the follower wheel 220, and the follower wheel 220 meshes with the internal wheel 217. Please refer to Figure 4 and Figure 6 . First, the follower wheel 220 will revolve along the input wheel 216. Since the input wheel 216 is rotatably connected to the connecting rod 218, the follower wheel 220 will also rotate along the connecting rod 218. If the follower wheel 220 only rotates along the connecting rod 218, the connecting rod 218 will not rotate. Since the output sleeve 22 is connected to multiple connecting rods 218, it will not rotate accordingly. Therefore, there will be no rotation in the crushing box 31. Since the internal wheel 217 meshes with multiple follower wheels 220, at this time, all the rotational speeds of the input wheel 216 are transmitted to the counterweight wheel 21, and there will be a situation where the output sleeve 22 does not rotate but the counterweight wheel 21 rotates in the opposite direction. All the rotational speeds are transmitted to the rotation of the counterweight wheel 21, and the output sleeve 22 does not rotate. At this time, it is an extreme situation where the output sleeve 22 does not move. Since the roller 26 presses on the raised block 27, as the counterweight wheel 21 rotates, the roller 26 will rotate along multiple raised blocks 27. Then the spring 211 is always in a compressed and released state. At this time, the output sleeve 22 is stuck. Therefore, in this state, the motor 12 will rotate and will not be burned out.

[0025] Due to the action of the spring 211, a corresponding elastic force will be applied to the roller 26, and the elastic forces of multiple springs 211 will be superimposed. Therefore, a moment of rotation will occur between the roller 26 and the raised block 27. When this moment makes the counterweight wheel 21 and the output sleeve 22 in a synchronous rotation state, since the follower wheel 220 meshes with the internal wheel 217, and the internal wheel 217 and the connecting rod 218 are in a synchronous state, there will be a situation where the input wheel 216 drives multiple follower wheels 220 to only revolve. Therefore, all the speeds are transmitted to the output sleeve 22 through the follower wheel 220. At this time, it is the normal rotation state of the motor 12. Since it is in a directly connected state, the rotational speed is very fast. When the corresponding garbage is put into the crushing box 31, due to the large inertia of the crushing pieces 34 on both sides, a great crushing effect will be produced on the garbage. And when a jamming situation occurs, the moment will be transmitted to the output sleeve 22. When this moment exceeds the pressure of multiple springs 211, the roller 26 will rotate along multiple raised blocks 27. Therefore, the follower wheel 220 will rotate along the connecting rod 218, thus avoiding a rigid connection. When a large moment occurs, the rigid connection will be released, resulting in an overload protection state and improving the safety of use.

[0026] When the counterweight wheel 21 and the output sleeve 22 are in a state of synchronous rotation, not only the torque for rotation is provided by the pressure of the spring 211, but also the torque is provided by the frictional force between the multiple friction rings 28 and the friction grooves 221. Moreover, the faster the output sleeve 22 rotates, the greater the torque generated. Since the guide holes 223 on the synchronizing block 29 are slidably connected to the guide rod 222, the synchronizing block 29 can expand outward along the guide rod 222, and an outward thrust is also applied by the push spring 224. As the output sleeve 22 rotates, a centrifugal force is generated, and a greater centrifugal force is generated as the rotation speed increases. At this time, the centrifugal force acts on the friction rings 28 through the multiple friction grooves 221, and since there are multiple friction rings 28, the friction force range is set. When the output sleeve 22 is in synchronous rotation with the counterweight wheel 21, the generated frictional force is the largest, so the largest torque is also generated. The sum of the torque generated by the frictional force and the torque generated by the spring 211 is the connection torque between the counterweight wheel 21 and the output sleeve 22. When the torque generated by jamming exceeds the sum of the two torques, the connection will be disconnected. By increasing the torques of the two, sufficient crushing force can be ensured, guaranteeing the crushing of garbage, and thus the crushing process is completed.

[0027] The crushing mechanism includes a crushing box 31 fixedly installed on the fixed frame 11. A driving shaft 32 and a driven shaft 33 are rotatably installed in the crushing box 31. The output sleeve 22 is connected to the driving shaft 32. The crushing mechanism further includes a plurality of crushing pieces 34, and the plurality of crushing pieces 34 are respectively installed on the driving shaft 32 and the driven shaft 33 in an alternating manner. Synchronous wheels 35 are installed on both the driving shaft 32 and the driven shaft 33, and the two synchronous wheels 35 are meshed with each other.
