Description

Technical Field

[0001] This invention relates to the field of waste soil crushing technology, specifically a waste soil crushing device for highway construction. Background Technology

[0002] Highway construction waste crushing equipment is a mechanized device used to efficiently remove road surface waste, gravel, and other waste. It typically consists of a mobile chassis, a rotating brush or scraper, a sealed storage tank, and a dust suppression system. It can automatically collect, transport, and crush waste, thereby reducing dust pollution, adapting to complex construction environments, improving cleaning efficiency, and reducing labor costs, while also meeting environmental protection and multi-functional needs.

[0003] A search revealed Chinese patent CN117654721A, which includes a base plate with a first device box on top and a second device box on top of the first device box. The second device box has an opening on its side and a guide plate that mates with the opening on its outer wall. The second device box has a first chamber communicating with the opening inside. This invention utilizes the tilt angle of the inclined fan blades to concentrate the slag in the first screening zone. However, as the inclined fan blades rotate, centrifugal force causes the slag to continuously diffuse outwards. The different apertures of the first sieve holes in the first screening zone, the second sieve holes in the second screening zone, and the third sieve holes in the third screening zone are used to adaptively screen the slag, thus classifying it for more effective subsequent processing and better overall results.

[0004] However, the above-mentioned scheme relies on manual collection and disposal of construction waste, and the device itself does not have an autonomous cleaning function, resulting in a low degree of automation and a high dependence on manual labor efficiency. Furthermore, the scheme does not consider dust control for the construction waste, leading to a large amount of dust being generated during disposal, further interfering with manual efficiency and polluting the surrounding environment. On the other hand, construction waste can usually be recycled after crushing, but the above-mentioned scheme lacks the function of controlling the crushed size of the construction waste, relying solely on the sieve holes in the screening area to screen the crushed construction waste. This means that the construction waste needs to be reprocessed in the subsequent recycling process, and the sieve holes cannot be adjusted after installation and the disassembly and assembly process is cumbersome. In other words, the above-mentioned scheme lacks the function of adjusting the crushing effect of construction waste according to the ground environment. Summary of the Invention

Detailed Implementation

[0029] 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 described embodiments 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1 to 9 The present invention provides a technical solution: a slag crushing device for highway construction, including a vehicle body 1, a sweeping mechanism, a spraying and pumping mechanism, and a crushing component. A drive shaft 11 is provided on one side of the vehicle body 1, and a driven shaft 12 is provided on the side of the vehicle body 1 away from the drive shaft 11. A base 13 is fixedly connected to the vehicle body 1 near the driven shaft 12. A fixing frame 14 is fixedly connected to the upper surface of the vehicle body 1 at the position corresponding to the base 13. The drive shaft 11 is driven by a built-in power system. Both the drive shaft 11 and the driven shaft 12 are provided with motion wheels to enable the device to move.

[0031] The crushing assembly includes a collection mechanism for temporarily storing slag, a control mechanism for completing the slag crushing operation, and an adjustment mechanism for controlling the particle size of the slag. The collection mechanism includes a collection frame 4 that is detachably installed inside the vehicle body 1 near the base 13. The control mechanism includes a fixed seat 5 that is fixedly connected to the base 13 and the fixed frame 14.

[0032] In this scheme, the built-in power system drives the drive shaft 11 to rotate, and the drive shaft 11 further drives the motion wheel to rotate synchronously to realize the overall movement of the vehicle body 1. During the movement, the sweeping mechanism operates synchronously, sweeping the slag on both sides of the movement route to the front of the movement route while moving. Then, the slag is cleaned up as the device moves, thus achieving the effect of expanding the slag cleaning area in the scheme.

[0033] While the vehicle is moving, the spraying and suction mechanism works simultaneously to collect and transport the debris along the route to the crushing component, preventing fine debris from causing dust. At the same time, dust suppressant is sprayed onto the cleaned road surface to further improve the road surface's dust resistance.

[0034] The control mechanism in the crushing component further grinds and crushes the conveyed slag according to the set particle size. The crushed slag particles are of uniform size and are stored in the collection mechanism. After the overall cleaning operation is completed, the stored slag is manually removed. During this process, the particle size of the crushed slag can be freely adjusted by the adjustment mechanism to meet the crushing requirements of different working environments.

[0035] Among them, the driven shaft 12 and the drive shaft 11 together realize the balance and movement of the vehicle body 1, the base 13 limits and fixes the collection mechanism, and the fixing frame 14 limits and fixes the control mechanism.

[0036] Example 2: Please refer to Figure 3 and Figure 4 This embodiment further illustrates the following based on Embodiment 1: The sweeping mechanism includes a sweeping disc 2 made of flexible material that is in frictional contact with the ground. Two sets of sweeping discs 2 are provided and are located on both sides of the vehicle body 1 near the drive shaft 11. The top of each of the two sweeping discs 2 is fixedly connected to a rotating wheel 21. The top of each of the two rotating wheels 21 passes through the vehicle body 1 and is rotatably connected to the vehicle body 1. A sprocket 22 is meshed and driven on the outer contour of each of the two rotating wheels 21. The two sprockets 22 pass through the vehicle body 1 and are rotatably connected to the vehicle body 1. A chain 23 is driven to the end of each of the two sprockets 22 away from the vehicle body 1. The other end of each of the two chains 23 is driven and sleeved on the outer contour of the drive shaft 11.

[0037] As can be seen from Embodiment 1, the built-in motor drives the drive shaft 11 to rotate, enabling the entire device to move forward while the cleaning mechanism works synchronously. Figure 3 For example, the drive shaft 11 rotates clockwise to achieve movement. At this time, the overall movement direction of the device is horizontal to the right. Since the drive shaft 11 and the sprocket 22 are connected by a chain 23, the sprocket 22 rotates clockwise synchronously. At this time, the meshing of the sprocket 22 with the rotating wheel 21 further causes the rotating wheel 21 and the cleaning disc 2 to rotate synchronously. Figure 3 From the perspective of the viewer, the rotating wheels 21 and the sweeping discs 2 on both sides of the drive shaft 11 rotate in the same direction, pointing towards the middle section of the drive shaft 11, that is, the sweeping discs 2 on both sides rotate in opposite directions.

[0038] Therefore, during the movement of the vehicle body 1, the two sweeping discs 2 simultaneously contact the road surface and continuously rotate and rub against it. As the sweeping discs 2 rotate and rub against the road surface, the gravel on the road surface is swept and pushed to the front of the middle section of the drive shaft 11, thereby effectively expanding the area of ​​the slag removal scheme and improving the cleaning efficiency.

[0039] Example 3: Please refer to Figure 5 This embodiment further illustrates the following based on Embodiment 2: The spraying and suction mechanism includes a spray nozzle 3 fixedly connected to the middle section of the vehicle body 1 near the drive shaft 11. A suction pump 32 is fixedly connected to the end of the spray nozzle 3 away from the drive shaft 11. The suction pump 32 is fixedly connected to the middle section of the vehicle body 1. A flow channel 1 31 and a flow channel 2 33 are sequentially opened between the spray nozzle 3 and the suction pump 32 from top to bottom. The spray nozzle 3 and the suction pump 32 are connected through the flow channel 1 31 and the flow channel 2 33. A conduit 36 ​​is connected to the top of the suction pump 32. An atomizing nozzle 35 is provided on the outer contour of the flow channel 2 33 at the bottom of the spray nozzle 3. A scraper plate 34 is fixedly connected at the bottom of the spray nozzle 3 near the flow channel 1 31 and away from the drive shaft 11.

[0040] The flow channel 2 33 is equipped with a water tank and multiple one-way valves that control the direction of water flow.

[0041] As can be seen from Example 1, the spraying and suction mechanism completes the cleaning of the slag on the road surface. When the device is moving, the suction pump 32 works synchronously and forms an airflow circulation in the spraying and suction mechanism. At this time, the suction pump 32 draws air and slag from the outside through the flow channel 31. Then the air is discharged through the flow channel 33, and the slag is further transported to the crushing component through the conduit 36.

[0042] As the vehicle body 1 moves, the spray nozzle 3 moves synchronously with the vehicle body 1. At this time, the scraper plate 34 at the bottom of the spray nozzle 3 continuously contacts the road surface. As the spray nozzle 3 moves, the scraper plate 34 scrapes the road surface, concentrating the accumulated slag on the road surface directly below the opening of the flow channel 31. Then, through the negative pressure effect formed in the flow channel 31 by the suction pump 32, the slag on the road surface is sucked into the flow channel 31. Subsequently, the slag is further transported to the crushing component through the conduit 36.

[0043] The pressurization effect synchronously formed by the suction pump 32 in the second flow channel 33 gradually increases the pressure in the water tank of the second flow channel 33, thereby discharging the liquid in the water tank to the atomizing nozzle 35 through the one-way valve; the liquid is a mixture of dust suppressant and water, and the specific mixing ratio needs to be determined according to the actual scenario requirements; and further atomized and sprayed out through the atomizing nozzle 35, the sprayed liquid evenly covers the road surface where the slag has been cleared, thereby achieving the effects of dust reduction and protection.

[0044] Example 4: Please refer to Figures 6 to 8 This embodiment further illustrates the following based on Embodiment 3: The collection mechanism also includes a motor 41 disposed inside the base 13. The top end of the motor 41 is fixedly connected to an output shaft 42 that passes through the base 13 and extends upward. The top end of the output shaft 42 is fixedly connected to a connecting rod 43. The end of the connecting rod 43 away from the output shaft 42 is fixedly connected to an upwardly extending transmission shaft 45. The end of the connecting rod 43 away from the output shaft 42 is fixedly connected to a horizontally outwardly extending scraper 44.

[0045] The side of the collection frame 4 closest to the base 13 is set to be arc-shaped, and the length of the scraper 44 is set to fit the inner contour of the arc portion of the collection frame 4.

[0046] A threaded cylinder 51 is screwed to the center of the fixed base 5. A crushing cone 52 is provided inside the threaded cylinder 51. The bottom end of the crushing cone 52 is penetrated by a drive shaft 45 and is connected to the drive shaft 45. A ball head 54 is connected to the top end of the crushing cone 52. A positioning shaft 55 is fixedly connected to the top end of the ball head 54. The positioning shaft 55 is fixedly connected to the bottom of the middle section of the fixed frame 14. A material collecting ring 53 is fixedly connected to the top end of the threaded cylinder 51.

[0047] The adjustment mechanism includes a knob 6 that passes through the fixed base 5 and is rotatably connected to one corner of the upper surface of the fixed base 5. An adjustment gear 61 is fixedly connected to the outer contour of the knob 6. The adjustment gear 61 is attached to the upper surface of the fixed base 5. A transmission gear ring 62 is meshed and connected to the outer contour of the adjustment gear 61. The transmission gear ring 62 is fixedly connected to the outer contour of the top end of the threaded cylinder 51.

[0048] As can be seen from Examples 1 and 3, the slag on the road surface is collected and transported to the crushing component through the conduit 36. The crushing component then completes the grinding and crushing operation of the slag. The slag transported through the conduit 36 ​​is poured onto the surface of the collecting ring 53 and then falls into the gap between the threaded cylinder 51 and the crushing cone 52.

[0049] At this time, the starter motor 41 drives the output shaft 42 to rotate, and the output shaft 42 further drives the connecting rod 43, scraper 44, and drive shaft 45 to revolve. Since the drive shaft 45 is connected to the crushing cone 52, and the position of the drive shaft 45 through the crushing cone 52 is offset from the axis of the crushing cone 52, and as... Figure 2 and Figure 8 As shown, the crushing cone 52 is initially placed eccentrically. The top of the crushing cone 52 is aligned with the center of the ball head 54, while the bottom of the crushing cone 52 revolves around the axis of the output shaft 42. That is, there is a small angular deviation between the axis of the crushing cone 52 and the axis of the output shaft 42. At this time, the bottom of the crushing cone 52 revolves synchronously around the axis of the output shaft 42. The position of the top of the crushing cone 52 is restricted by the ball head 54. The positioning shaft 55 is fixedly connected to the fixing frame 14. That is, the position of the ball head 54 is fixed along with the positioning shaft 55. The position of the top of the crushing cone 52 cannot be moved. At this time, the revolution of the bottom of the crushing cone 52 will cause the entire crushing cone 52 to rotate eccentrically.

[0050] Since the threaded cylinder 51 is stationary, as the crushing cone 52 rotates off-axis, the size of the gap between the bottom of the crushing cone 52 and the inner wall of the threaded cylinder 51 changes synchronously, thereby grinding the slag accumulated between the crushing cone 52 and the threaded cylinder 51. The ground slag particles fall into the collection mechanism through the gap between the bottom of the crushing cone 52 and the threaded cylinder 51.

[0051] Therefore, the maximum gap between the bottom of the crushing cone 52 and the threaded cylinder 51 is the maximum size through which the slag particles can pass. As can be seen from the above, when the crushing cone 52 rotates off-axis, the size of the gap between its bottom and the inner wall of the threaded cylinder 51 changes synchronously. The gap between the crushing cone 52 on the off-axis side and the threaded cylinder 51 is smaller, while the gap between the crushing cone 52 on the other side and the threaded cylinder 51 is larger. This gap size is the maximum size through which the slag particles can pass. Slag particles larger than this size cannot pass through the gap between the bottom of the crushing cone 52 and the threaded cylinder 51, and thus continue to remain between the threaded cylinder 51 and the crushing cone 52 and continue to be subjected to the grinding effect of the rotation of the crushing cone 52 until they are further crushed to a size through which they can pass.

[0052] Furthermore, the fallen soil particles are spread evenly inside the semi-circular outline of the collection frame 4. With the synchronous revolution of the connecting rod 43 and the scraper 44 driven by the output shaft 42, the scraper 44 intermittently scrapes the inner wall of the semi-circular outline of the collection frame 4, thereby sweeping the soil particles inside the semi-circular outline of the collection frame 4 further into the collection frame 4, avoiding the soil particles from accumulating too high and obstructing the subsequent falling of soil particles. After the cleaning operation is completed, the personnel disassemble or open the collection frame 4 to complete the removal of the crushed soil. At this time, the soil particles are of uniform size.

[0053] On the other hand, when it is necessary to control the grinding size of the slag particles, it is achieved by controlling the adjustment mechanism. At this time, the operator turns the knob 6, and the knob 6 drives the adjustment gear 61 to rotate synchronously. The adjustment gear 61 further drives the transmission gear ring 62 to rotate. Since the transmission gear ring 62 is fixedly connected to the outer edge of the top of the threaded cylinder 51, the threaded cylinder 51 rotates synchronously with the transmission gear ring 62.

[0054] Furthermore, since the threaded cylinder 51 is screwed to the fixed seat 5, and the fixed seat 5 is restricted by the fixed connection between the base 13 and the fixed frame 14, i.e., the fixed seat 5 is in a fixed state, the rotation of the threaded cylinder 51 along with the transmission gear ring 62 will cause it to rise and fall under the screwing action of the fixed seat 5; when the height of the crushing cone 52 is kept constant due to the joint restriction of the transmission shaft 45 and the ball head 54, i.e., when the operator rotates the knob 6, a relative height difference appears between the threaded cylinder 51 and the crushing cone 52. At this time, the bottom end of the threaded cylinder 51 deviates from the initial height, because the crushing cone 52 is designed... The screw cylinder 51 is shaped like a cone. When the bottom end of the screw cylinder 51 rises, the gap between it and the surface of the crushing cone 52 increases. When the bottom end of the screw cylinder 51 falls, the gap between the surfaces of the crushing cone 52 decreases. The size of the gap between the bottom end of the screw cylinder 51 and the surface of the crushing cone 52 is the maximum passing size of the slag particles. Therefore, the control mechanism can adjust the particle size of the slag grinding by rotating the knob 6 in both directions. The control mechanism can continue to work during the adjustment process without stopping the machine, thus effectively ensuring the crushing efficiency of the solution and meeting the needs of various scenarios with different crushing degrees.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
