Description

Technical Field

[0001] This invention relates to the field of road repair technology, and in particular to an automatic crushing, impurity removal and recycling equipment vehicle for old cement road materials. Background Technology

[0002] Against the backdrop of continuous advancement in highway infrastructure construction, a large number of cement pavements have developed defects such as surface peeling, network cracks, and base settlement due to factors such as extended service life and long-term heavy vehicle traffic, which urgently require repair, reinforcement, or renovation.

[0003] The hoppers of existing equipment vehicles are mostly fixed structures. Different road sections and construction scenarios have different requirements for the specifications and particle size of crushed materials. In addition, the cement blocks produced by road demolition are of uneven size. Fixed feed hoppers cannot flexibly adjust the crushed stone processing specifications according to actual construction needs, making it difficult to adapt to the changing construction standards. This results in poor material screening effect, making it difficult to produce crushed stone that meets construction requirements, which in turn affects the quality of subsequent road paving. Summary of the Invention

Detailed Implementation

[0022] To make the technical objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention 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, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. The present invention provides an automatic crushing, impurity removal, and recycling equipment vehicle for old cement road materials, including a vehicle body 1. Hydraulic cylinders 2 are symmetrically fixedly connected to the vehicle body 1. A bucket frame 3 is fixedly connected to the output end of the hydraulic cylinders 2. An adjustment component 4 is provided on the bucket frame 3. The adjustment component 4 includes a motor 41 fixedly connected to the side wall of the bucket frame 3. A rotating shaft 42 is rotatably connected to the inner side wall of the bucket frame 3. The rotating shaft 42 is fixedly connected to the output end of the motor 41. A mounting plate 43 is fixedly connected to the side wall of the rotating shaft 42. The interior of the mounting plate 43 is hollow, and multiple sliding grooves 44 are evenly spaced on the side wall of the mounting plate 43. A sealing plate 45 is installed on the inner wall of the sliding groove 44. The sealing plate 45 is located on the front and rear sides of the sliding groove 44. A cylinder installed inside the mounting plate 43 is installed on its side wall. After the position of the bucket rod 412 is adjusted, the sealing plate 45 can block the opening of the sliding groove 44 between the bucket rod 412, so that the sliding groove 44 is in a closed state. This effectively prevents small gravel, dust and other debris from entering the interior of the mounting plate 43, avoids jamming and wear of internal components, and further improves the stability and service life of the equipment.

[0025] The inner wall of the mounting plate 43 is symmetrically fixedly connected to a sliding seat 46, and the top surface of the sliding seat 46 is slidably connected to a sliding plate 47. Multiple cam grooves 48 are evenly opened on the sliding plate 47, and the number of cam grooves 48 and sliders 411 can be adjusted according to the actual situation.

[0026] An electric actuator 49 is fixedly connected to the inner wall of the mounting plate 43, and the output end of the electric actuator 49 is fixedly connected to the sliding plate 47. A guide rod 410 is symmetrically fixedly connected to the inner wall of the sliding seat 46, and a slider 411 is slidably connected to the guide rod 410. The slider 411 is slidably connected to the cam groove 48 through a cam. A bucket rod 412 is fixedly connected to the side wall of the slider 411. The bucket rod 412 is slidably connected to the sliding groove 44. A hollow plate 413 is fixedly connected to one side of the bucket rod 412, and a sliding plate 415 is fixedly connected to the other side of the bucket rod 412. The sliding plate 415 is fixedly connected to one side of the foremost bucket rod 412, and a hollow plate 413 is provided on one side of the rearmost bucket rod 412. When the bucket rod 412 is adjusted to a suitable position according to the road conditions, the sealing plate 45 moves under the drive of the cylinder and moves to a position that fits against the side wall of the bucket rod 412, thereby completely sealing the opening of the sliding groove 44.

[0027] The sliding plate 415 is slidably connected to the hollow plate 413. A spring 414 is fixedly connected to the bottom of the sliding plate 415, and the spring 414 is fixedly connected to the hollow plate 413. A feed inlet 5 is provided at the front end of the vehicle body 1, and a guide plate 6 is provided inside the feed inlet 5. A crushing assembly 7 is provided inside the vehicle body 1. The crushing assembly 7 includes a crushing box 71 installed inside the vehicle body 1. A drawer is provided at the bottom of the crushing box 71 to collect smaller impurities and dust screened by the screen plate 715, preventing impurities and dust from accumulating at the bottom of the crushing box 71. At the same time, it is convenient for operators to regularly pull out the drawer for cleaning and maintenance of normal equipment operation. Motor 3 72 is fixedly connected to the side wall, and rotating rod 1 73 is rotatably connected to the inner wall of crushing box 71. One end of rotating rod 1 73 is fixedly connected to the output end of motor 3 72, and the other end of rotating rod 1 73 is fixedly connected to gear 1 74. Protective covers are provided on both sides of crushing box 71. The protective covers can provide comprehensive protection for motor 3 72, gear 1 74, and gear 2 77, effectively isolating the flying stone and dust generated during the crushing process, avoiding damage to the parts from impact or affecting the transmission effect due to dust accumulation. At the same time, it can also prevent operators from contacting the moving parts and causing safety hazards, ensuring stable operation of the equipment and operational safety.

[0028] The inner wall of the crushing box 71 is rotatably connected to a rotating rod 75. One end of the rotating rod 75 is fixedly connected to a disc 76, and the other end of the rotating rod 75 is fixedly connected to a gear 77. The gear 77 meshes with the gear 74. Crushing rollers 78 are installed on both the rotating rod 73 and the rotating rod 75. A limiting block 79 is fixedly connected to the side wall of the crushing box 71. A crank 710 is hinged to both the gear 77 and the disc 76. A pressure rod 711 is hinged to the end of the crank 710. The pressure rod 711 is slidably connected to the limiting block 79. The side wall of the crushing box 71 is symmetrically provided with annular grooves 712, which provide guidance for the up and down sliding of the horizontal plate rod 716, preventing the horizontal plate rod 716 from deviating or jamming when sliding, and also limiting the horizontal plate rod 716 to prevent it from deviating from the sliding trajectory and affecting the vibration effect of the screen plate 715.

[0029] A support plate 713 is fixedly connected to the inner wall of the crushing box 71. A telescopic rod 714 is fixedly connected to the top surface of the support plate 713. A return torsion spring is installed inside the telescopic rod 714. The return torsion spring can provide a stable return force for the screen plate 715, so that the screen plate 715 can quickly and smoothly return to the initial position after being hit. During the reciprocating vibration, it can not only improve the screening efficiency of the crushed stone, but also assist the crushed stone to move in the inclined direction with the help of the vibration thrust, so that the crushed stone is conveyed more smoothly and avoids the accumulation of crushed stone on the screen plate 715, further improving the smoothness and stability of the overall operation.

[0030] The telescopic end of the telescopic rod 714 is fixedly connected to a screen plate 715. Horizontal rods 716 are fixedly connected to both sides of the screen plate 715, and the horizontal rods 716 are slidably connected to the annular groove 712. A conveyor belt 8 is installed inside the vehicle body 1. Multiple metal-attracting separators 81 are spaced evenly on the conveyor belt 8. Each metal-attracting separator 81 integrates an electromagnetic coil. When the equipment is operating, the electromagnetic coil is powered on, generating a strong magnetic field. Utilizing the adsorption properties of the magnetic field, it adsorbs various metal impurities such as metal fragments and steel rebar residue mixed in with the crushed stone conveyed on the surface of the conveyor belt 8, achieving separation of metal from the crushed stone. The metal-attracting separators 81 are evenly distributed along the width of the conveyor belt 8, ensuring that all areas of the conveyor belt 8 surface are covered with adsorption material for metal impurities. This allows for comprehensive capture of various metal impurities and efficient separation of metal impurities from the crushed stone. Meanwhile, a collection tray is placed at the corresponding position at the bottom of the conveyor belt 8. When the metal-absorbing strip 81 on the conveyor belt 8 rotates to the top of the collection tray, the electromagnetic coil inside the metal-absorbing strip 81 is automatically de-energized, the magnetic field disappears, and the metal-absorbing strip 81 loses its adsorption capacity. The metal impurities previously adsorbed on the strip fall into the collection tray below under its own gravity, which makes it convenient for operators to regularly clean and recycle the metal impurities in the collection tray, thus avoiding the waste of metal resources.

[0031] A dust collection device 9 is installed on the vehicle body 1. This dust collection component consists of a fan, a suction pipe, a suction hood, and a collection box. The fan generates a continuous negative pressure suction force, which is transmitted through the suction pipe to the suction hood at the end of the suction pipe. The suction hood is located above the conveyor belt 8. It can not only quickly suck the dust generated during crushing, screening, and conveying into the suction pipe, but also suck away the lighter fine impurities mixed on the conveyor belt 8 after screening. This achieves simultaneous cleaning of dust and lighter impurities. The sucked-in dust and lighter impurities are transported to the collection box through the suction pipe for centralized storage. No additional cleaning process is required. This effectively avoids dust spreading into the air and causing environmental pollution, and also reduces the mixing of lighter impurities into qualified crushed stone, further improving the quality of secondary utilization of old materials.

[0032] In this invention, the vehicle body 1 first travels to the road requiring cleaning via its movable wheels. The internal power system of the vehicle body 1 drives the movable wheels to rotate, causing the entire vehicle to move smoothly. The direction and speed can be flexibly adjusted to reach the work area. Because the degree of road damage, density of old materials, and road width vary, the required working range and clearance of the bucket arm 412 also differ. Therefore, the position of the bucket arm 412 needs to be adjusted using the adjustment component 4 to adapt to different road conditions and to effectively screen the old materials.

[0033] Specifically, the electric actuator 49 drives the sliding plate 47 to slide along the top surface of the sliding seat 46 on the inner wall of the mounting plate 43. The top surface of the sliding seat 46 has a groove, which guides and limits the movement of the sliding plate 47, preventing it from shifting or jamming during sliding and ensuring smooth movement. When the sliding plate 47 moves under the drive of the electric actuator 49, the cam groove 48 on the sliding plate 47 pushes the cam on the slider 411 to move synchronously. Since the slider 411 is slidably connected to the guide rod 410 fixed to the inner wall of the sliding seat 46, the guide rod 410 restricts the slider 411 from moving in the front-back direction, thus making the slider 411 only move horizontally along the guide rod 410. When the slider 411 moves, it synchronously drives the bucket rod 412 fixed to it to slide horizontally in the sliding groove 44, realizing the position adjustment of multiple bucket rods 412.

[0034] During the horizontal movement of the bucket arm 412, the fixed sliding plate 415 simultaneously slides out from inside the hollow plate 413. The sliding plate 415 and the hollow plate 413 engage to fill the gaps between the bucket arms 412 caused by their movement, effectively preventing small stones, dust, and other debris generated during operation from entering the mounting plate 43 and causing damage to components. When the bucket arm 412 is adjusted to a suitable position according to the road conditions, the sealing plate 45, driven by the cylinder, moves towards the foremost and rearmost bucket arms 412 respectively, thereby filling the remaining gaps in the sliding groove 44 and further achieving complete sealing of the sliding groove 44, ensuring the safe operation of the internal components of the equipment.

[0035] Once the bucket boom 412 is adjusted to the appropriate position, the hydraulic cylinder 2 mounted on the vehicle body 1 drives the bucket frame 3 to move downwards, ensuring the bucket boom 412 is in close contact with the road surface. At this point, the vehicle body 1 is started moving forward again. During this movement, the bucket frame 3 and the bucket boom 412 work together to collect old cement blocks, gravel, and other old materials from the road surface. An inclined baffle is located on one side of the mounting plate 43, which acts as a barrier to limit the collected old materials, preventing them from falling from the rear of the mounting plate 43 during dumping. This ensures the old materials are smoothly gathered within the mounting plate 43, preparing for subsequent dumping operations.

[0036] Then, the hydraulic cylinder 2 is started again, driving the bucket frame 3 to rise and raising the collected old material to a suitable height with the feed inlet 5. Then, the motor 41 is started to drive the fixed rotating shaft 42 to rotate, which in turn drives the mounting plate 43 to flip, pouring the pre-screened cement blocks into the feed inlet 5 at the front of the vehicle body 1. The blocks fall from the feed inlet 5 onto the guide plate 6 and then into the crushing box 71 inside the vehicle body 1 for secondary crushing.

[0037] When the crushed stone enters the crushing box 71, the motor 3 72 is started to drive the rotating rod 1 73 fixed thereto to rotate. Since the other end of the rotating rod 1 73 is fixedly connected to the gear 1 74, and the gear 1 74 meshes with the gear 2 77, the rotation of the gear 1 74 will drive the gear 2 77 and the rotating rod 2 75 fixed thereto to rotate synchronously. Both the rotating rod 1 73 and the rotating rod 2 75 are equipped with crushing rollers 78. The two crushing rollers 78 rotate synchronously with the rotating rod, squeezing and impacting the cement blocks that enter the crushing box 71 to crush the large cement waste into crushed stone that is required for subsequent use.

[0038] When gear 77 rotates, it drives disk 76 to rotate synchronously through rotating rod 75. Both disk 76 and gear 77 are hinged with cranks 710. As disk 76 and gear 77 rotate, the cranks 710 hinged to the outside of them make circular motion. The pressure rod 711 hinged to the end of crank 710 slides with limit block 79. Under the limiting and guiding action of limit block 79, pressure rod 711 continuously strikes the horizontal bar 716 on both sides of screen plate 715 with the movement of crank 710.

[0039] This striking action causes the horizontal bar 716 to slide up and down in the annular groove 712 opened on the side wall of the crushing box 71, which in turn drives the screen plate 715 to vibrate up and down. The telescopic rod 714 at the bottom of the screen plate 715 can extend and retract in coordination with the vibration of the screen plate 715, effectively ensuring that the screen plate 715 vibrates smoothly.

[0040] After the crushed stone is screened by the sieve plate 715, the crushed stone will fall onto the conveyor belt 8 installed inside the vehicle body 1 along the tilt angle of the sieve plate 715. Multiple metal-absorbing strips 81 are evenly spaced on the conveyor belt 8 to absorb and separate metal impurities mixed in with the stone, preventing metal impurities from entering the stone and affecting the quality of subsequent reuse of the recycled material.

[0041] Meanwhile, the dust generated during the operation is centrally processed by the dust collection component installed on the vehicle body 1. After the suction fan is started, negative pressure is generated, and the dust generated during the operation is sucked into the collection box through the suction pipe for centralized collection. After screening and impurity removal, the qualified crushed stone is transported to the rear of the vehicle body 1 by the conveyor belt 8, and then transported to the outside through the opening on the rear of the vehicle body 1, and directly laid on the road to be repaired, thus completing the secondary utilization of cement waste.

[0042] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
