Description

Technical Field

[0001] The present invention relates to the technical field of solid waste recycling, and particularly relates to a device for recycling solid waste of highway pavement materials. Background Art

[0002] During the construction, maintenance and renovation of highways, a large amount of solid waste containing steel bars will be generated from abandoned cement concrete pavements. At present, the mainstream method for recycling steel bars in pavement concrete in the industry is still the simple mechanical crushing method. Such methods mainly rely on equipment such as jaw crushers and impact crushers to crush concrete blocks through strong extrusion and impact forces, so as to attempt to separate the steel bars.

[0003] In the actual operation process, when using the pure mechanical crushing method for separation, due to the complex chemical bonding, mechanical biting force and frictional force between the concrete and the steel bars, the two are closely combined. The mechanical equipment needs to run for a long time and apply huge forces, and it is also difficult to accurately separate, resulting in extremely low crushing efficiency and difficult to meet the requirements of large-scale engineering solid waste treatment.

[0004] In addition, during the crushing process, the violent collision and friction between the concrete blocks and the equipment components will also generate a large amount of dust. These dusts will not only cause serious harm to the respiratory systems of on-site operators, and it is not conducive to the physical health of the staff to be exposed to such an environment for a long time, but also once the dust drifts into the atmosphere, it will aggravate air pollution and affect the surrounding ecological environment.

[0005] Therefore, how to achieve efficient and environmentally friendly separation of steel bars and concrete in highway abandoned cement concrete pavements, reduce processing energy consumption, and at the same time reduce environmental pollution such as dust is an urgent problem to be solved by those skilled in the art.

[0034] An embodiment of the present application discloses a device for recycling solid waste of highway pavement materials.

[0035] Please refer to Figures 1 to 10 , in an embodiment of the present application, a device for recycling solid waste of highway pavement materials includes a machine body 100. A crushing channel 101 penetrating up and down is provided in the middle of the machine body 100. An electromagnetic heating assembly 200 fixedly installed on the top of the machine body 100 is hermetically communicated with the crushing channel 101. A feeding assembly 300 is fixedly and hermetically installed on the top of the electromagnetic heating assembly 200. A plurality of layers of sliding channels 102 communicating with the crushing channel 101 are symmetrically provided at both ends of the machine body 100. A crushing assembly 400 is installed inside the sliding channel 102. A water spraying and cooling assembly 500 is installed on the crushing assembly 400. A discharging assembly 600 is installed at the bottom of the machine body 100 corresponding to the crushing channel 101. A driving assembly 700 is installed on the machine body 100. The driving assembly 700 is in transmission connection with the crushing assembly 400 and the discharging assembly 600. Pumping assemblies 900 connected to the sliding channels 102 are symmetrically installed at both ends of the machine body 100. The feeding assembly 300 and the water spraying and cooling assembly 500 are both connected to the pumping assemblies 900.

[0036] The implementation principle of the device for recycling solid waste of highway pavement materials in an embodiment of the present application is as follows: During the operation, the road surface solid waste to be processed is first fed into the feeding assembly 300, and the solid waste fed into the feeding assembly 300 will enter the electromagnetic heating assembly 200. After the electromagnetic heating assembly 200 is started, the electromagnetic induction principle is used to generate an induced current in the metal parts such as steel bars contained in the solid waste, causing the steel bars to heat up quickly, and the heat is transferred to the surrounding concrete, causing the concrete to expand and crack due to the heat, destroying the bonding force between the concrete and the steel bars, and reducing the difficulty of subsequent crushing. The solid waste after heating falls into the crushing channel 101 below.

[0037] The crushing assembly 400 starts to work under the transmission of the driving assembly 700. The crushing assembly 400 reciprocates along the slideway 102 in the crushing channel 101, squeezing and impacting the solid waste treated by electromagnetic heating. Through the synergistic effect of the multiple layers of crushing assemblies 400, the solid waste is gradually crushed into smaller particles.

[0038] During the crushing process, the water spray cooling assembly 500 installed on the crushing assembly 400 is started to spray water to the crushing area. On the one hand, when spraying water for cooling, the temperature drop will cause micro cracks inside the concrete, and these micro cracks will expand and connect with each other, weakening the overall structural strength of the concrete, making it easier for the concrete to fall off the surface of the steel bar and promote separation; on the other hand, water spraying can effectively suppress the dust generated during the crushing process and reduce environmental pollution.

[0039] After being crushed and cooled, the material falls to the bottom of the machine body 100 through the crushing channel 101. At this time, the discharge assembly 600 connected to the driving assembly 700 starts to work, and the crushed material is discharged from the discharge assembly 600 for subsequent operations such as steel bar separation, material screening and reuse.

[0040] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the electromagnetic heating component 200 includes a mounting cylinder 201, which is fixedly and sealedly mounted on the top surface of the body 100, and an inner cylinder 202 is fixedly embedded inside the mounting cylinder 201. The inner cylinder 202 is connected to the crushing channel 101, and the inner cylinder 202 is made of ceramic material. An alternating coil 203 is wound between the outer side surface of the inner cylinder 202 and the inner side surface of the mounting cylinder 201, and the alternating coil 203 is connected to a power supply 204.

[0041] During the working process, the power supply 204 provides an alternating current to the alternating coil 203. An alternating current is a current whose magnitude and direction change periodically with time. When the alternating current passes through the alternating coil 203, according to Ampere's law and the principle of electromagnetic induction, the alternating coil 203 will generate an alternating magnetic field in the surrounding space. The magnitude and direction of this magnetic field change continuously with the change of the current. When the highway pavement solid waste containing steel bars enters the inner cylinder 202 through the feeding assembly, the alternating magnetic field will penetrate the inner cylinder 202 and act on the steel bars. Since the steel bars are conductors, the alternating magnetic field will generate an induced current inside the steel bars, and this current is called eddy current. According to Joule's law, heat is generated when current passes through a conductor. When the eddy current flows inside the steel bars, the steel bars will quickly heat up. After the steel bars heat up, their heat will be transferred to the surrounding concrete by means of heat conduction. Due to the heat transfer between the concrete and the steel bars, the concrete absorbs heat and its temperature rises, and the internal structure changes, resulting in a weakening of the bonding force between the concrete and the steel bars, creating favorable conditions for subsequent crushing and separation operations.

[0042] Please refer to Figures 1 to 10 , in a specific embodiment of the present application, the feeding assembly 300 includes a feeding hopper 301. The feeding hopper 301 is fixedly installed on the top of the electromagnetic heating assembly 200. An atomization channel 302 is opened inside the feeding hopper 301. A first water inlet pipe 303 that is hermetically connected to the atomization channel 302 is fixedly installed on the outer side surface of the feeding hopper 301. A first electric control valve 304 is fixedly and hermetically installed at one end of the first water inlet pipe 303 away from the feeding hopper 301. One end of the first electric control valve 304 away from the first water inlet pipe 303 is connected to the water pumping assembly 900; a plurality of spray holes 305 that are equidistantly distributed are opened on the inner side surface of the feeding hopper 301, and the spray holes 305 are communicated with the atomization channel 302.

[0043] During the working process, the feeding assembly 300 is connected to the water pumping assembly 900 through the first water inlet pipe 303, and the first electric control valve 304 controls the on-off of the water flow. When spray operation is required, the water pumping assembly 900 transports water to the first water inlet pipe 303. The water flows into the atomization channel 302 inside the feeding hopper 301. The atomization channel 302, as an annular or reticular cavity, evenly distributes the water to each spray hole 305. The water is sprayed out in an atomized form through the spray holes 305. When the highway pavement solid waste to be processed is put in from the top of the feeding hopper 301, the sprayed water mist makes full contact with the falling solid waste particles. The water mist can adsorb and wrap the dust particles, increasing their weight and causing them to settle, thus effectively suppressing the dust generated during the feeding process.

[0044] Please refer to Figures 1 to 10, in a specific embodiment of the present application, the crushing assembly 400 includes several layers of symmetrically arranged sliding plates 401. The sliding plates 401 are hermetically and slidably connected inside the slideway 102. Through grooves 402 penetrating the upper and lower sides thereof are formed on the sliding plates 401. Impact blocks 403 are installed at one end of the sliding plates 401 close to each other; two symmetrically arranged driving crankshafts 404 are rotatably connected to the body 100. One driving crankshaft 404 correspondingly penetrates inside the through grooves 402 on the multi-layer sliding plates 401 on the same side; a transmission member 800 is synchronously and drivingly connected to the two driving crankshafts 404, and the transmission member 800 is drivingly connected to the driving assembly 700.

[0045] During the working process, the driving assembly 700 transmits power to the two driving crankshafts 404 through the transmission member 800, causing the two driving crankshafts 404 to rotate synchronously. During the rotation of the eccentric part of the driving crankshaft 404, relative movement will be generated in the through groove 402. Since the driving crankshaft 404 penetrates inside the through grooves 402 of the multi-layer sliding plates 401 on the same side, the rotation of the driving crankshaft 404 will drive the sliding plates 401 to perform reciprocating linear motion inside the slideway 102. The sliding plates 401 on both sides perform synchronous and opposite reciprocating motions, driving the impact blocks 403 installed at the ends of the sliding plates 401 to perform periodic opposite impacts on the materials in the crushing channel 101. When the electromagnetic-heated concrete solid waste falls into the crushing channel 101, it is repeatedly impacted and squeezed by the impact blocks 403, thereby realizing crushing. Through the arrangement of the multi-layer sliding plates 401 and the impact blocks 403, crushing operations are simultaneously carried out at different height positions in the crushing channel 101, enabling the materials to experience multiple crushings during the falling process, improving the crushing efficiency and the crushing effect.

[0046] Please refer to Figures 1 to 10 , in a specific embodiment of the present application, the through groove 402 is arranged as a semi-circular arc, and the opening of the semi-circular arc faces the center of the crushing channel 101.

[0047] During operation, when the driving crankshaft 404 performs circular motion driven by the transmission member 800, its eccentric portion slides in the semicircular driving groove 402. Since the opening of the driving groove 402 faces the center of the crushing channel 101, when the driving crankshaft 404 drives the sliding plate 401 to move to the limit position away from the center of the crushing channel 101, as the driving crankshaft 404 continues to rotate, the semicircular driving groove 402 will coincide with the rotation direction of the driving crankshaft 404, and at this time, the driving crankshaft 404 will not drive the sliding plate 401 to move. When the eccentric portion of the driving crankshaft 404 moves to the end of the semicircular driving groove 402, it will drive the sliding plate 401 to move toward the center of the crushing channel 101. In this way, under the continuous rotation of the driving crankshaft 404, the sliding plate 401 forms intermittent reciprocating movement, that is, when the impact block 403 impacts the material in the crushing channel 101 in opposite directions, it will be quickly separated, and then it will be temporarily suspended after separation, so that the crushed concrete has enough time to fall down from the crushing channel 101, further improving the crushing efficiency and crushing effect.

[0048] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the transmission member 800 includes a first bevel gear 801 fixedly mounted on the two driving crankshafts 404 respectively, and a first mounting seat 802 is fixedly mounted on the body 100 corresponding to the two driving crankshafts 404, and the first mounting seat 802 is rotatably connected to the first rotating shaft 803, and the end of the first rotating shaft 803 close to the driving crankshaft 404 is fixedly connected to the second bevel gear 804, and the first bevel gear 801 is meshed with the second bevel gear 804 correspondingly, and the end of the first rotating shaft 803 away from the driving crankshaft 404 is fixedly connected to the first pulley 805, and the first transmission belt 806 is synchronously connected between the two first pulleys 805 and the driving assembly 700.

[0049] During operation, the driving assembly 700 transmits power to the two first pulleys 805 through the first transmission belt 806, so that the first pulleys 805 rotate around the first rotating shaft 803. The rotation of the first pulley 805 drives the first rotating shaft 803 to rotate, and the second bevel gear 804 at the end of the first rotating shaft 803 rotates accordingly. Since the second bevel gear 804 is meshed with the first bevel gear 801 fixed on the driving crankshaft 404, the transmission of the bevel gear pair transmits power from the first rotating shaft 803 in the horizontal direction to the driving crankshaft 404 in the vertical direction, realizing a 90° conversion of the power transmission direction, which is conducive to improving the layout of the installation structure. The two first pulleys 805 are driven simultaneously by the first transmission belt 806 to ensure that the two first rotating shafts 803 rotate synchronously. After the transmission of the bevel gear pair, the two driving crankshafts 404 obtain synchronous and unidirectional rotational power, thereby driving the sliding plates 401 and the impact blocks 403 on both sides to achieve synchronous opposite impact motion.

[0050] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the water spraying and cooling assembly 500 includes a second water inlet pipe 501 fixedly installed on the machine body 100. An inlet water channel 502 that is hermetically communicated with the second water inlet pipe 501 is provided inside the machine body 100. One end of the second water inlet pipe 501 away from the machine body 100 is connected to the water pumping assembly 900. A water spraying channel 503 is provided inside the impact block 403. A plurality of impact heads 405 are evenly distributed on one side of the impact block 403 away from the sliding plate 401. Water spraying holes 504 communicated with the water spraying channel 503 are provided on the outside of the impact heads 405 on one side of the impact block 403 away from the sliding plate 401. A plug pipe 505 is fixedly connected to one side of the impact block 403 close to the sliding plate 401. The plug pipe 505 is hermetically communicated with the water spraying channel 503. A jack 506 corresponding to the plug pipe 505 is provided on the sliding plate 401. The plug pipe 505 is hermetically slidably connected in the jack 506. One end of the jack 506 away from the plug pipe 505 penetrates through the side wall of the sliding plate 401. A water inlet hole 507 corresponding to the jack 506 on the side wall of the sliding plate 401 is provided on the machine body 100 at the position where the sliding plate 401 slides outwards to the limit position. The water inlet hole 507 is communicated with the inlet water channel 502.

[0051] During the working process, the water pumping assembly 900 transports water to the inlet water channel 502 inside the machine body 100 through the second water inlet pipe 501. When the sliding plate 401 slides outwards to the limit position driven by the driving crankshaft 404, the jack 506 on the side wall of the sliding plate 401 is aligned with the water inlet hole 507 on the machine body 100. At this time, the water in the inlet water channel 502 enters the plug pipe 505 through the water inlet hole 507 and the jack 506, and finally flows into the water spraying channel 503 inside the impact block 403. The water is sprayed out from the water spraying channel 503 through the water spraying holes 504 under the action of pressure. The water spraying holes 504 are located outside the impact heads 405, so that the sprayed water can cover the impact heads 405 and the surrounding areas.

[0052] When the impact block 403 impacts and crushes the concrete solid waste, the water spraying can not only reduce the temperature generated during the impact process. The temperature drop will cause microcracks to be generated inside the concrete. These microcracks will expand and communicate with each other, weakening the overall structural strength of the concrete, making the concrete easier to fall off from the surface of the steel bars and promoting separation. It can also inhibit the dust generated during the crushing process, reducing environmental pollution and the harm to the health of the operators. It can also moisten the concrete particles, contributing to the subsequent separation and screening processes.

[0053] Since the alignment of the socket 506 and the water inlet hole 507 only occurs when the sliding plate 401 slides outward to the extreme position, the water spraying process is synchronized with the movement cycle of the impact block 403. This means that water will be sprayed only after the impact block 403 completes one impact, avoiding the waste of water resources and water accumulation inside the device caused by continuous water spraying.

[0054] Please refer to Figures 1 to 10 In a specific embodiment of the present application, an adjusting rod 406 is rotatably connected inside the impact block 403, and the end of the adjusting rod 406 away from the impact block 403 passes through the sliding plate 401. An adjusting screw hole 407 is opened on the sliding plate 401 corresponding to the adjusting rod 406, and an adjusting stud 408 is fixedly connected to the adjusting screw hole 407 on the adjusting rod 406.

[0055] During operation, the adjusting rod 406 is connected to the inside of the impact block 403 by rotation, and one end of the adjusting rod 406 passes through the adjusting screw hole 407 on the sliding plate 401, and cooperates with the adjusting screw hole 407 through the fixedly connected adjusting stud 408. When the position of the impact block 403 needs to be adjusted, the adjusting rod 406 is rotated. Since the adjusting stud 408 and the adjusting screw hole 407 are threadedly matched, according to the principle of threaded transmission, as the adjusting rod 406 rotates, the adjusting stud 408 moves linearly in the adjusting screw hole 407, thereby driving the adjusting rod 406 to move in the axial direction. Because the adjusting rod 406 is connected to the impact block 403 by rotation, the axial movement of the adjusting rod 406 will push or pull the impact block 403, so that the impact block 403 is adjusted in position on a plane perpendicular to the sliding direction of the sliding plate 401, thereby adjusting the distance between the two impact blocks 403 that are in conflict with each other, and thus can adapt to different steel bar sizes and concrete materials, thereby improving the scope of application.

[0056] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the discharge component 600 includes a frame 601, which is fixedly mounted on the bottom of the body 100, and three groups of second mounting seats 602 distributed in a triangle are fixedly mounted on the frame 601, and each group of second mounting seats 602 is rotatably connected to a second rotating shaft 603, one of which is fixedly mounted with a second pulley 604, and a second transmission belt 605 is transmission-connected between the second pulley 604 and the driving component 700, and rollers 606 are fixedly connected to the second rotating shaft 603, and a conveyor belt 607 is transmission-connected to the three rollers 606, and the conveyor belt 607 is obliquely arranged toward one side of the bottom of the body 100, and a first collection frame 609 is placed correspondingly at the lower end of the obliquely arranged conveyor belt 607, and a second collection frame 610 is placed correspondingly at the high end of the obliquely arranged conveyor belt 607.

[0057] During operation, the driving component 700 transmits power to the second pulley 604 through the second conveyor belt 605, and the second pulley 604 drives the second rotating shaft 603 fixedly connected thereto to rotate. Since the rollers 606 on the three second rotating shafts 603 are connected by the conveyor belt 607, when one of the second rotating shafts 603 rotates, it will drive the other two second rotating shafts 603 to rotate synchronously, so that the conveyor belt 607 operates cyclically.

[0058] When controlling the conveyor belt 607 to run from the lower end to the upper end in an inclined setting, the material after being crushed and cooled by spraying water falls from the crushing channel 101 at the bottom of the machine body 100 onto the inclined conveyor belt 607. Due to the inclined setting of the conveyor belt 607, the material will have different motion states during transportation due to its own shape and the friction of the conveyor belt. The steel bar material is separated from the concrete material after being repeatedly impacted in opposite directions by the crushing component 400 during the crushing process, but will not be cut off. Therefore, the separated steel bar will have a certain length and will be clamped in the crushing component 400 and will not fall directly. So the end of the steel bar away from the crushing component 400 will abut against the surface of the conveyor belt 607 and move upward along the conveyor belt 607 to the upper end, and finally fall into the second collection box 610; while the concrete fragments will slide or roll along with the water flow formed by the water sprayed by the water spraying and cooling component 500 to the lower end of the conveyor belt 607 during transportation and fall into the first collection box 609, thus realizing the preliminary separation of the steel bar and the concrete.

[0059] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the outer surface of the conveyor belt 607 is fixedly and sealingly connected with a retaining edge 608 near its side surface, and both the conveyor belt 607 and the retaining edge 608 are made of elastic materials.

[0060] During operation, when the conveyor belt 607 cyclically transports materials driven by the rollers 606, the retaining edge 608 fixedly and sealingly connected to the outer surface of the conveyor belt 607 near the side surface moves synchronously therewith. Since both the conveyor belt 607 and the retaining edge 608 are made of elastic materials, during the transportation of the material, when the material slides or tumbles to the side surface of the conveyor belt 607 due to factors such as inertia and gravity, the elastic retaining edge 608 can block the concrete fragments and the water flow, restricting the concrete fragments and the water flow within the effective transportation area in the middle of the conveyor belt 607, ensuring that the concrete fragments and the water flow can accurately fall into the first collection box 609 along the conveyor belt 607.

[0061] Please refer to Figures 1 to 10, in a specific embodiment of the present application, the driving assembly 700 includes a driving member 701. A third mounting seat 702 is fixedly installed on the machine body 100, and the driving member 701 is fixedly installed on the third mounting seat 702. A first driving pulley 703 and a second driving pulley 704 are fixedly installed on the output shaft of the driving member 701. The first driving pulley 703 is in transmission connection with the crushing assembly 400, and the second driving pulley 704 is in transmission connection with the discharging assembly 600.

[0062] During the working process, when the driving member 701 is started, its output shaft drives the first driving pulley 703 and the second driving pulley 704 to rotate synchronously. The first driving pulley 703 transmits power to the driving crankshaft 404 in the crushing assembly 400 through the first transmission belt 806 in the transmission member 800, causing the driving crankshaft 404 to rotate, and then driving the sliding plate 401 and the impact block 403 to perform reciprocating motions to realize the crushing of the material. The second driving pulley 704 transmits power to the second pulley 604 of the discharging assembly 600 through the second transmission belt 605, driving the conveyor belt 607 to operate, and completing the conveying and separation of the crushed material. By using one driving member 701 to drive two different working components simultaneously, the coordinated operation of the crushing and conveying functions is realized.

[0063] Please refer to Figures 1 to 10 , in a specific embodiment of the present application, the driving member 701 is configured as an electric motor. The electric motor has stable power output characteristics and can continuously and stably provide power for the crushing assembly 400 and the discharging assembly 600, ensuring the long-term and high-efficiency operation of the solid waste recycling device and reducing equipment failures and reduced processing efficiency caused by power fluctuations.

[0064] Please refer to Figures 1 to 10 , in a specific embodiment of the present application, the water pumping assembly 900 includes sealing plates 901 detachably and sealingly connected to both ends of the machine body 100. The inner side surface of the sealing plate 901 and the outer end surface of the sliding plate 401 form a sealing cavity 902 inside the slideway 102. A third water inlet pipe 903 and a drain pipe 904 are fixedly and sealingly installed on the machine body 100. The third water inlet pipe 903 and the drain pipe 904 are communicated with the sealing cavity 902. A one-way water inlet valve 905 is installed on the third water inlet pipe 903, and a one-way drain valve 906 is installed on the drain pipe 904. One end of the one-way water inlet valve 905 away from the third water inlet pipe 903 is connected to an input pipe 907, and the input pipe 907 is connected to a water source; one end of the one-way drain valve 906 away from the drain pipe 904 is connected to a water collecting main pipe 908, and the water collecting main pipe 908 is respectively connected to the second water inlet pipe 501 in the water spraying and cooling assembly 500 and the first water inlet pipe 303 in the feeding assembly 300.

[0065] During the working process, when the driving crankshaft 404 drives the sliding plate 401 to reciprocate within the slideway 102, the volume of the sealing cavity 902 formed by the outer end face of the sliding plate 401 and the inner side face of the sealing plate 901 changes periodically: when the sliding plate 401 slides inward (i.e., towards the center of the crushing channel 101), the volume of the sealing cavity 902 increases, and a negative pressure is formed inside. At this time, the one-way water inlet valve 905 opens, and water from the water source is injected into the sealing cavity 902 through the input pipe 907, completing the water absorption process. When the sliding plate 401 slides outward (i.e., away from the center of the crushing channel 101), the volume of the sealing cavity 902 decreases, and the internal water pressure increases. At this time, the one-way water drainage valve 906 opens, and the water in the sealing cavity 902 is transported through the drainage pipe 904 and the water collecting main pipe 908 to the second water inlet pipe 501 of the water spraying and cooling assembly 500. At the same time, the first water inlet pipe 303 of the feeding assembly 300 is also connected to the water pumping assembly 900, realizing water supply to the atomization channel 302.

[0066] The reciprocating motion of the sliding plate 401 is powered by the driving assembly 700. The water pumping assembly 900 does not require an additional power source, but utilizes the motion energy of the crushing assembly 400 to drive the water cycle. The water absorption and drainage processes are automatically controlled through one-way valves to ensure the unidirectional flow of water and prevent backflow.

[0067] Please also refer to Figures 1 to 10 In a specific embodiment of the present application, the input pipe 907 is connected to the first collection frame 609, and a filter 909 is provided inside the first collection frame 609 corresponding to the input pipe 907.

[0068] During the operation of the device, after preliminary separation by the discharge assembly 600, lighter materials such as concrete fragments fall into the first collection frame 609. The water in the first collection frame 609 gradually accumulates as the materials pile up. This water may carry impurities such as concrete debris and dust. At this time, the water pumping assembly 900 operates, and the change in the volume of the sealing cavity 902 generates a negative pressure. Under the action of the one-way water inlet valve 905, the water in the first collection frame 609 is sucked into the sealing cavity 902 through the input pipe 907. During this process, the filter 909 at the connection port of the input pipe 907 plays a role in intercepting larger particle impurities such as concrete debris and dust in the water, and only allowing relatively clean water to enter the water pumping assembly 900 through the input pipe 907. After being pressurized, it is then transported through the water collecting main pipe 908 to the second water inlet pipe 501 of the water spraying and cooling assembly 500 and the feeding assembly 300 for use in the cooling and dust suppression of the crushing area and other links.

[0069] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
