Description

Technical Field

[0001] The present invention relates to the technical field of concrete block crushing, and in particular to a concrete block crushing system. Background Art

[0002] The concrete block crushing system is a device system specially used to process discarded or damaged concrete blocks. Its main working principle is to drive the crushing hammer head inside the crusher to rotate at high speed through the motor, impact and crush the concrete blocks placed in the crushing chamber, and finally break them into smaller particles or fragments. These crushed concrete blocks can be used for a variety of purposes, such as road and bridge construction, construction field, and soil improvement in agriculture. The core equipment of the concrete block crushing system is the concrete crusher, and its crushing principle is based on the principles of physics and mechanics. The crushing hammer head repeatedly impacts and hits the concrete block at high speed, causing the concrete block to break and fracture inside. The entire crushing process is completed in the crushing chamber, and the crushed concrete blocks are discharged through the discharge port.

[0003] The current concrete crushing system has some obvious shortcomings when in use, as follows: First, the traditional concrete crushing system mainly relies on the mechanical force of the crushing roller to crush the concrete blocks, but because concrete often contains hard materials such as steel bars, these steel bars will greatly increase the difficulty of crushing, and the crushing roller may be hindered by the steel bars during the crushing process, resulting in reduced crushing efficiency and even possible damage to the key components of the crusher; Second, in the concrete crushing process, due to the action of mechanical force, the concrete blocks are broken into smaller particles, and a large amount of dust will be generated at the same time. This dust will not only fly around the work site, causing environmental pollution, but also have a serious impact on the health of the operators. The steel bars and other impurities in the concrete blocks will be broken into small particles and attached to the filter screen. Over time, the iron filings and impurities on the filter screen will continue to accumulate, gradually forming a thick layer of blockage, which will not only hinder the normal crushing of the concrete blocks, but also reduce the processing efficiency of the crusher.

[0037] Example, see Figure 1-Figure 8A concrete block crushing system includes a mounting frame 1 and a motor 2. A crushing box 3 and a mounting seat 205 are mounted and connected on the upper side of the mounting frame 1. The motor 2 is fixedly arranged on the mounting seat 205. A discharge port 302 is mounted and connected on the lower side wall of the mounting frame 1. An arc filter screen 301 is installed between the crushing box 3 and the discharge port 302. A connecting box 4 is rotatably connected to the rear end of the crushing box 3. An inlet 401 for placing concrete blocks is mounted and connected to the upper end of the connecting box 4. A handle 303 for limiting the connecting box 4 is installed on the front end of the motor 2. The system also includes:

[0038] Transmission dust reduction component: The transmission dust reduction component is arranged on one side of the output end of the motor 2, and the transmission dust reduction component is used to transmit the power of the motor 2 and to perform dust reduction treatment on the concrete block;

[0039] Disturbance and crushing assembly: The disturbance and crushing assembly is arranged on the transmission dust reduction assembly, and the disturbance and crushing assembly is used to perform disturbance and crushing processing on the concrete blocks on the arc filter 301;

[0040] Electromagnetic transmission component: The electromagnetic transmission component is arranged inside the crushing box 3. The electromagnetic transmission component assists in crushing the concrete blocks and can also automatically clean the arc filter 301;

[0041] Further, the transmission dust reduction assembly includes a transmission box 5 and a transmission shaft 201, the transmission box 5 is hollow inside, the two ends of the transmission box 5 are respectively fixedly connected to the transmission shaft 201 and the output end of the motor 2, a water storage chamber 203 is arranged inside the transmission shaft 201, a water injection port 501 is connected through the side wall of the transmission box 5, water can be injected into the transmission box 5 through the water injection port 501, and a sealing plug 502 is sealed inside the water injection port 501 to prevent water from overflowing from the transmission box 5, and a plurality of groups of water spray ports 204 are equidistantly arranged on the transmission shaft 201, and the ends of the water spray ports 204 respectively penetrate the outer wall of the transmission shaft 201 and the inner wall of the water storage chamber 203;

[0042] It should be noted that the transmission shaft 201 is set in a single-sided closed shape, and the transmission box 5 is sealed between the transmission shaft 201 and the output end of the motor 2 to ensure the sealing of the connection. The inner cavity of the transmission box 5 is connected to the water storage cavity 203, and the water entering the transmission box 5 will enter the water storage cavity 203.

[0043] Reference Figure 5-Figure 12The disturbance crushing assembly includes a mounting sleeve 202, a sealing disk 8 and two mounting disks 7. A plurality of mounting holes are annularly provided on the mounting disk 7 and the sealing disk 8. Baffle rods 701 and rotating rods 9 are arranged at intervals in adjacent mounting holes. The plurality of baffle rods 701 are fixedly clamped on the mounting disk 7 and the sealing disk 8 and their ends are flush with the end surfaces of the mounting disk 7 and the sealing disk 8 respectively. The baffle rod 701 plays the role of connecting the mounting disk 7 and the sealing disk 8. A cotter pin 901 is provided at the end of the rotating rod 9 and is rotatably clamped between the cotter pin 901 and the mounting disk 7 for limiting the rotating rod 9. A plurality of crushing knives 10 and a limiting stopper sleeve 905 are slidably provided on the rotating rod 9. The plurality of crushing knives 10 are staggeredly distributed on the rotating rod 9 through the limiting stopper sleeve 905. The distribution of the crushing knives 10 can be adjusted by adjusting the length of the limiting stopper sleeve 905, thereby ensuring that the concrete blocks can be fully crushed.

[0044] It should be noted that the crushing knives 10 on adjacent rotating rods 9 are staggered to ensure comprehensive crushing of concrete blocks. The sealing plate 8 and the two mounting plates 7 are welded and connected to a whole through a plurality of baffle rods 701, and the whole is welded and connected to the mounting sleeve 202. There is a gap between the end of the crushing knife 10 and the arc filter 301, which ensures that the concrete blocks on the arc filter 301 can be fully crushed while avoiding collision with the arc filter 301. The mounting sleeve 202 is fixedly arranged on the transmission shaft 201 inside the crushing box 3. In this way, the power can be transmitted to the installation sleeve 202 through the transmission shaft 201, thereby driving the crushing knife 10 to perform a crushing operation. A nozzle matching the water spray port 204 is provided on the installation sleeve 202, and the nozzle is a one-way pressure type setting. When the transmission shaft 201 rotates at a faster speed, under the action of centrifugal force, the water in the water storage chamber 203 will be sprayed out through the water spray port 204 and the nozzle, so that the dust inside the equipment can be reduced. The installation disk 7 and the sealing disk 8 are staggeredly arranged on the installation sleeve 202, and the interior of the rotating rod 9 is a single-sided closed hollow setting;

[0045] Further, the electromagnetic transmission component includes a conductive slip ring 6 and a conductive rod 902 rotatably arranged inside the rotating rod 9, the outer wall of the conductive slip ring 6 is fixedly connected with a positioning bolt 602, the side wall of the crushing box 3 is provided with a through hole matching the positioning bolt 602, the positioning bolt 602 is threadedly connected with a positioning nut 603, the conductive slip ring 6 is installed and connected with the crushing box 3 through the positioning bolt 602 and the positioning nut 603, the inner side of the conductive slip ring 6 is provided with a conductive area 604, the outer side of the conductive area 604 is connected with a transmission line 601, and power can be transmitted to the conductive area 604 through the transmission line 601, the crushing box 3 is provided with a notch matching the transmission line 601, the inner side of the conductive area 604 is provided with a sliding cavity 605, and the inner side wall of the conductive area 604 is electrically connected with a first elastic gasket 606 and a second elastic gasket 607;

[0046] The end of the conductive rod 902 extends to the inside of the sliding cavity 605, and the sealing disk 8 and the conductive slip ring 6 are sealed and fitted to ensure the internal sealing of the conductive slip ring 6. The conductive slip ring 6 is annular and its cross section is concave. A limit slider 608 is provided at the end of the conductive slip ring 6 away from the positioning bolt 602. A limit groove 801 matching the limit slider 608 is provided on the sealing disk 8. The limit groove 801 and the limit slider 608 can strengthen the sealing inside the conductive slip ring 6. An insulating baffle 904 is rotatably clamped inside the mounting hole of the sealing disk 8 near the end of the rotating rod 9. The insulating baffle 904 is fixedly connected to the conductive rod 902 to avoid the risk of power leakage.

[0047] Furthermore, the rotating rod 9 is made of silicon steel, which is a commonly used high magnetic permeability material and has good tensile strength and compressive strength. The first elastic gasket 606 and the second elastic gasket 607 are respectively located on the outside and inside of the conductive area 604, and the adjacent first elastic gaskets 606 and second elastic gaskets 607 are arranged at intervals. The first elastic gasket 606 and the second elastic gasket 607 are both arc-shaped conductive metal sheets. The conductivity coefficient of the first elastic gasket 606 is greater than the conductivity coefficient of the second elastic gasket 607. The first elastic gasket 606 is selected from a material with high conductivity, such as carbon fiber, silver-plated rubber, or conductive polymer. These materials have high conductivity and can provide better conductivity. In rubber or polymer The material matrix is ​​filled with high-density conductive particles (such as carbon black, silver particles or copper powder) to improve the overall conductivity coefficient. The second elastic gasket 607 is selected from materials with low conductivity, such as ordinary rubber or low-conductive polymers, and can be filled with low-density conductive particles (such as a small amount of carbon black or nickel powder). Its conductivity should be significantly lower than that of the first elastic gasket 606. A plurality of electromagnetic coils 903 are fixedly connected to the conductive rod 902 located inside the rotating rod 9. The plurality of electromagnetic coils 903 are equidistantly distributed along the central axis of the conductive rod 902. The electromagnetic coils 903 are electrically connected to the conductive rod 902. The setting of the elastic gasket can transfer the power of the conductive area 604 to the conductive rod 902, thereby driving the electromagnetic coils 903 to work.

[0048] It should be noted that: there are gaps between the conductive area 604, the first elastic gasket 606 and the second elastic gasket 607 and the sealing disk 8, which prevents electricity from being transmitted to the sealing disk 8. There is a gap between the end of the conductive rod 902 and the conductive area 604. The conductive rod 902 is located at the center of the inner cavity of the sliding cavity 605. The distance between the conductive rod 902 and the inner wall of the sliding cavity 605 is smaller than the height of the protrusions of the first elastic gasket 606 and the second elastic gasket 607, which ensures that when the conductive rod 902 rotates with the sealing disk 8, the conductive rod 902 can intermittently contact the first elastic gasket 606 or the second elastic gasket 607, thereby driving the electromagnetic coil 903 to be in working states of different intensities.

[0049] The working principle of the concrete block crushing system is as follows: first, unplug the sealing plug 502, insert the water pipe into the water injection port 501 to inject water into the transmission box 5, and because the inner cavity of the transmission box 5 is connected with the water storage chamber 203, the water entering the transmission box 5 will also enter the water storage chamber 203 accordingly. When the water in the transmission box 5 is saturated, insert the sealing plug 502, put the concrete block to be crushed into the device from the feed port 401, and the concrete block will fall onto the arc filter 301 inside the crushing box 3, start the motor 2, and the motor 2 will first drive the transmission box 5 to rotate, and then drive the transmission shaft 201 and the installation sleeve 202. The rotating rod 9 rotates, thereby driving the mounting plate 7 and the sealing plate 8 to rotate. Accordingly, the crushing knife 10 rotates on the rotating rod 9 while rotating with the rotating rod 9, and contacts the blocking rod 701 under the action of centrifugal force, so as to realize the crushing of large concrete blocks on the arc filter 301. In addition, the blocking rod 701 and the rotating rod 9 can be used to smoothly move the concrete blocks on the arc filter 301. The crushed concrete blocks will fall through the arc filter 301 and be discharged from the discharge port 302. The concrete blocks that are not completely crushed will remain on the arc filter 301, and the crushing knife 10 will continue to crush them.

[0050] When the speed of the transmission shaft 201 increases (this usually indicates an increase in the crushing demand because the number or hardness of the concrete blocks increases), the centrifugal force will increase with the increase in the speed, that is, as the speed increases, the centrifugal force will push the water in the water storage chamber 203 to be forced out through the water spray port 204 and the nozzle. The one-way pressure nozzle design will automatically adjust the water spraying amount according to the actual workload of the crusher without manual intervention. When crushing concrete, the device automatically sprays water to suppress the generation of dust. The water mist can not only reduce the flying of dust, but also reduce the impact of dust on the surrounding environment and the health of operators, while increasing the visibility of the work site and improving the safety of the operation; spraying The water system also provides cooling for the transmission shaft 201. Since the crushing process generates a lot of heat, if this heat is not dissipated in time, it may cause overheating of mechanical parts, thereby affecting the performance and life of the equipment. The cooling effect of the water storage chamber 203 on the transmission shaft 201 can maintain the temperature of the mechanical parts within a safe working range. In this design, the use of water is very efficient because it is passively sprayed only when needed, which saves resources and ensures the best working condition of the equipment. In addition, since it is driven by centrifugal force, this water spray system does not require additional pumps or electronic control units, thereby reducing the complexity of the system and potential maintenance costs;

[0051] The conductive slip ring 6 in the electromagnetic transmission component is installed and connected inside the crushing box 3 through the positioning bolt 602 and the positioning nut 603. The power supply is connected to the conductive area 604 of the conductive slip ring 6 through the transmission line 601. When the rotating rod 9 (made of silicon steel to enhance the magnetic properties) rotates, the internal conductive rod 902 also rotates. The rotating conductive rod 902 can intermittently contact the conductive area 604 through the elastic gasket (the first elastic gasket 606 and the second elastic gasket 607), thereby controlling the current transmitted to the electromagnetic coil 903; when the current reaches the conductive rod 902, the current is guided to the electromagnetic coil 903 located on the conductive rod 902. When the current passes through the winding in the electromagnetic coil 903, according to the law of electromagnetic induction , a magnetic field is generated around the electromagnetic coil 903, and the strength of the magnetic field is proportional to the strength of the current; these coils are distributed along the conductive rod 902, and can generate electromagnetic forces of different levels according to the current strength transmitted by the conductive rod 902. The magnetic force generated by the electromagnetic coil 903 is used to assist the crushing knife 10 in its work. When the crushing knife 10 crushes the concrete block, the magnetic force generated by the electromagnetic coil 903 directly acts on the steel bars in the concrete block. This magnetic force helps to weaken the bonding force between the steel bars and the concrete. Under the actual crushing action of the crushing knife 10, combined with the assistance of the electromagnetic force, the steel bars can be more smoothly separated from the crushed concrete matrix, thereby improving the crushing efficiency and the separation effect of the concrete material;

[0052] In order to prevent power leakage and external pollution, the conductive slip ring 6 and the conductive rod 902 are both designed with sealing disks 8, which are used in conjunction with the limiting slider 608 and the limiting groove 801 to ensure that power is transmitted in a sealed environment. By controlling the contact frequency and strength (the power supply strength of the transmission line 601 and the rotation speed of the motor 2) between the conductive rod 902 and the first elastic gasket 606 and the second elastic gasket 607, the activation state of the electromagnetic coil 903 can be adjusted, thereby adjusting the crushing force and efficiency.

[0053] In addition, during the crushing process, iron filings and impurities are often accumulated on the filter screen, which will affect the processing efficiency of the crusher. The traditional cleaning method requires stopping the machine for manual cleaning, which is not only time-consuming and labor-intensive, but may also cause harm to the operator. By using the electromagnetic coil 903, an alternating magnetic field is generated by energizing, and the magnetic field can excite eddy currents inside the iron filings and impurities. Since the shapes of the iron filings and impurities are irregular, the reaction force generated by the eddy currents can cause them to move, so that the iron filings and impurities accumulated on the arc filter screen 301 are separated from the filter screen by the magnetic force, which can not only improve the processing efficiency of the device, but also reduce the labor intensity and downtime of manual cleaning.

[0054] In summary, the design of the entire system enables the coordinated work between the mechanical components and the electromagnetic components to provide efficient energy utilization and precise control when crushing concrete blocks, and can adjust the working state of the electromagnetic coil 903 according to the crushing requirements to achieve the best crushing effect while maintaining the sealing and safe operation of the system.
