Description

Technical Field

[0001] The invention belongs to the technical field of roadbed construction, in particular to a roadbed construction filling device. Background Art

[0002] Roadbed construction and filling is a key process in road engineering to form a roadbed structure layer that meets the design requirements by layered paving and compacting materials. The core is to make the natural foundation reach sufficient strength, stability and uniformity through artificial filling to provide reliable support for the road surface structure. Similar to "building blocks", loose soil or stones are piled up in layers, and each layer is compacted by a roller, eventually forming a stable base like a cake, ensuring that the road surface will not sink due to soft foundation.

[0003] In the current existing technology, during the compaction of the base surface, when the moisture content of the filled soil is high, its viscosity will increase. At this time, the moisture between the soil particles plays the role of an adhesive, making it easy for the soil to adhere to the surface of the compaction cylinder. For example, when the roadbed is constructed in a humid clay area, the surface of the compaction cylinder will be more obviously adhered to by soil. The soil adhered to the compaction cylinder will not only affect the compaction of the soil by the compaction cylinder, but also cause a certain amount of resource loss when it is removed.

[0004] To this end, the present invention provides a roadbed construction filling device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a roadbed construction filling device described in the present invention comprises a base, a rectangular frame is fixedly installed at the bottom of the base, a pressure cylinder is rotatably connected to the inner wall of the rectangular frame, a cylinder driving motor is fixedly installed at one end of the pressure cylinder, a soil collecting box is fixedly installed at the bottom of the base, the soil collecting box is placed on one side of the pressure cylinder, a cylinder cleaning assembly is arranged on the outer wall of the pressure cylinder, the cylinder cleaning assembly comprises a scraping block, the cylinder cleaning assembly is used to scrape the soil attached to the surface of the pressure cylinder through the scraping block, a soil collecting assembly is arranged inside the soil collecting box, the soil collecting assembly is used to recycle the soil scraped by the cylinder cleaning assembly, a control cabin is fixedly installed on the top of the base, and a tripod is fixedly installed on one side of the base;

[0007] During use, the operator enters the control chamber and controls the operation of various parts of the device through the control chamber loading system, providing control for the compaction operation of the device. Subsequently, the operator drives the drum motor to drive the drum to rotate and compact the soil on the roadbed. When the drum rotates to compact the soil, the drum cleaning component scrapes the surface of the drum through the scraper block to prevent the outer surface of the drum from being attached to the soil, which affects the compaction operation of the drum on the soil laid on the roadbed. At the same time, the soil collecting component in the soil collecting box collects the soil scraped off by the scraper block in a centralized manner to prevent the soil attached to the drum from being lost during the subsequent cleaning process. The drum cleaning component and the soil collecting component cooperate with each other to reduce the impact of the soil attached to the drum on the compaction operation when the drum is compacting the soil. At the same time, the attached soil can also be centrally recovered and reused, reducing the waste of resources and playing a role in soil recycling.

[0008] Preferably, the drum cleaning assembly also includes scraping mouths, which are opened at both ends of the scraper block. The scraper block is fixedly mounted on the inner wall of the rectangular frame, and the scraper block is placed directly above the pressing drum. The inner wall of the scraper block is slidably connected to the outer surface of the pressing drum, and the scraping mouth is in contact with the outer surface of the pressing drum. When the drum driving motor drives the pressing drum machine to rotate to compact the soil, the scraping mouths on the scraper block scrape the surface of the pressing drum. When soil is attached to the surface of the pressing drum, the scraping mouths scrape the soil from the outer surface of the pressing drum, thereby removing the soil attached to the outer surface of the pressing drum and preventing the soil from sticking to the pressing drum. When the pressing drum rotates, the soil drives the remaining soil on the roadbed to wrap around the outer surface of the pressing drum, resulting in the loss of roadbed soil.

[0009] Preferably, a hinged rod is fixedly installed on one side of the outer wall of the scraper block, and a soil retaining plate is hingedly connected to the outer wall of the hinged rod. A soil sliding port is opened on the inner wall of the soil retaining plate. When the scraping port scrapes the outer surface of the pressure cylinder, the soil has a certain viscosity when the humidity is high. Therefore, when the soil is scraped by the scraping port and leaves the surface of the pressure cylinder, the angle between the soil retaining plate, the pressure cylinder and the scraping port is limited, and the soil scraped by the scraping port will be placed at the angle between the three. Through the continuous scraping of the outer wall of the pressure cylinder by the scraping port, the soil placed at the angle will become more and more, and the soil will slide downward along the soil sliding port, so that the soil placed at the angle between the three will slide downward away from the three, thereby preventing the scraped soil from accumulating between the three and affecting the scraping operation of the scraping port.

[0010] When the cam is in a state of being moved along the axis of the two wheels, the cam is moved along the axis of the two wheels, and the cam is moved along the axis of the two wheels respectively.

[0011] Preferably, a cover plate is fixedly mounted on the outer wall of the scraper block, and a plurality of vibrating soil springs are arranged between the inner wall of the cover plate and the top of the earth retaining plate. When the pressure cylinder pushes the push rod to open the earth retaining plate, when the earth retaining plate contacts one end of the cover plate, the earth retaining plate stops moving and the protrusion loses contact with the push rod. Through the elastic setting of the vibrating soil spring, the earth retaining plate will be reset, and the protrusion is driven by the pressure cylinder to rotate continuously. The protrusion continuously pushes the push rod to hinge open the earth retaining plate, and the earth retaining plate is pushed to be hinged and reset by the vibrating soil spring, thereby realizing continuous shaking of the earth retaining plate. By arranging the vibrating soil spring to reset the earth retaining plate, compared with resetting it by gravity, it can be avoided that the earth retaining plate cannot be reset well due to excessive accumulation of soil at the angle limit between the earth retaining plate, the pressure cylinder and the scraper mouth.

[0012] Preferably, the soil collecting component includes a soil transporting motor, which is fixedly mounted on the outer wall of the soil collecting box. A conveyor belt is provided inside the soil collecting box. The output end of the soil transporting motor is fixedly connected to the drive shaft in the conveyor belt. When the soil retaining plate is opened upward and contacts the cover plate, the soil retaining plate will be limited by the cover plate, causing a knocking vibration. The soil placed in the soil sliding port will be knocked and fall downward. Through the limiting setting, the soil in the soil sliding port will fall onto the conveyor belt. By driving the soil transporting motor to drive the conveyor belt to rotate, the soil fallen on the conveyor belt will move along the conveying direction of the conveyor belt to the mud placement area in the soil collecting box, thereby realizing the recovery of the soil.

[0013] Preferably, a limit block is fixedly installed on the bottom of the inner wall of the soil collecting box, the limit block is placed on the lower side of the pressure cylinder, one end of the conveyor belt is placed on one side of the limit block and is slidably connected to the outer wall of the limit block, and the retaining plate is placed directly above the conveyor belt and the limit block. Since the limit block is placed on the lower side of the pressure cylinder, when the pressure cylinder rotates, the center position of the pressure cylinder should be placed on the inner side of the limit block. Through its continuous rotation, soil can be prevented from falling from the gap between the pressure cylinder and the limit block to the outside of the device, and the setting of the limit block plays a limiting role.

[0014] Preferably, a scraper plate is fixedly installed inside the soil collecting box, and the top of the scraper plate is slidably connected to the outer wall of the conveyor belt. A plurality of water leakage holes are opened on the inner wall of the soil collecting box, and a water-absorbing cotton board is fixedly installed on the inner wall of the soil collecting box, and the water-absorbing cotton board is placed above the plurality of water leakage holes. The outer wall of the scraper plate is fixedly connected to one side of the water-absorbing cotton board. When the conveyor belt drives the soil into the mud placing area, the scraper plate scrapes the outer wall of the conveyor belt, thereby scraping the soil retained on the conveyor belt into the mud placing area, playing the role of scraping the soil off the surface of the conveyor belt. When the soil is retained in the mud placing area in the soil collecting box, the soil will be placed on the top of the water-absorbing cotton board. Through the water absorption characteristics of the water-absorbing cotton board, the water-absorbing cotton board will absorb the moisture in the soil, thereby reducing the humidity of the soil, which is conducive to its subsequent recycling. The water leakage hole is opened to facilitate the outflow of water absorbed in the water-absorbing cotton board, playing the role of water outlet.

[0015] Preferably, an electric rail is fixedly installed on the outer wall of the soil collecting box, and an electric slider is slidably connected to the inner wall of the electric rail. A connecting block is fixedly installed on one end of the electric slider, and a bulldozer is fixedly installed on one end of the connecting block. The outer walls of the connecting block and the bulldozer are slidably connected to the inner wall of the soil collecting box, and the outer wall of the bulldozer is slidably connected to the outer walls of the absorbent cotton board and the scraper board. When the compaction operation is completed, the electric slider is driven to slide in the electric rail. When the electric slider slides in the electric rail, the electric slider drives the bulldozer to slide in the mud placement area in the soil collecting box through the connecting block, thereby pushing the soil placed on the top of the absorbent cotton board, pushing the soil out of the soil collecting box, thereby taking out the soil for subsequent recycling.

[0016] Preferably, a limit plate is fixedly installed on one side of the soil collecting box, and a blocking plate is hinged on one side of the soil collecting box. The limit plate is placed outside the blocking plate, and a reset spring is directly provided on one side of the blocking plate and the limit plate. When the electric slider drives the bulldozer to push the soil, the blocking plate will be opened on one side of the soil collecting box by the thrust, and the soil placed in the built-in mud area of ​​the soil collecting box will be pushed out of the device from the blocking plate by the bulldozer. When the bulldozer completely pushes out the soil in the mud area, the electric slider drives it to reset, and under the elastic push of the reset spring, the blocking plate will reset, thereby blocking the opening to prevent the soil from flowing out of the blocking plate when the soil is recovered, thereby blocking the outflow of soil.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. A roadbed construction filling device described in the present invention, when the pressure drum rotates to compact the soil, the cleaning drum component scrapes the surface of the pressure drum through the scraper block to prevent the outer surface of the pressure drum from being attached to the soil and affecting the compaction operation of the pressure drum on the soil laid on the roadbed; at the same time, the soil collecting component in the soil collecting box collects the soil scraped off by the scraper block to prevent the soil attached to the pressure drum from being lost during the subsequent cleaning process; the cleaning drum component and the soil collecting component cooperate with each other to reduce the influence of the soil attached to the pressure drum on the compaction operation to a certain extent, and the attached soil can also be collected and reused to reduce the waste of resources.

[0019] 2. The roadbed construction filling device described in the present invention, when the driving drum motor drives the pressure drum to rotate to compact the soil, the scraping mouth on the scraper block scrapes the surface of the pressure drum. When the surface of the pressure drum is adhered to soil, the scraping mouth scrapes the soil from the outer surface of the pressure drum, thereby removing the soil adhered to the outer surface of the pressure drum and preventing the soil from adhering to the pressure drum. When the pressure drum is rotated, the soil drives the remaining soil on the roadbed to cover the outer surface of the pressure drum, resulting in the loss of roadbed soil.

[0020] 3. The roadbed construction filling device described in the present invention limits the angle between the retaining plate, the pressure cylinder and the scraper mouth, so that the soil scraped by the scraper mouth will be placed at the angle between the three. Through the continuous scraping of the outer wall of the pressure cylinder by the scraper mouth, the soil placed at the angle will become more and more, and the soil will slide downward along the sliding mouth, so that the soil placed at the angle between the three will leave the three and slide downward, preventing the scraped soil from accumulating between the three and affecting the scraping operation of the scraper mouth.

[0021] 4. The roadbed construction filling device described in the present invention, when the protrusion rotates, the protrusion will push the push rod to rotate through the protrusion setting. When the push rod is pushed by the protrusion, the retaining plate will be opened on one side of the scraper block through the hinge rod. Through the continuous rotation of the protrusion, the retaining plate will be continuously opened on one side of the scraper block through the hinge rod to perform a shaking operation. The soil placed in the sliding mouth will accelerate the downward flow speed driven by its shaking, thereby playing the role of shaking the soil to slide down.

[0022] 5. The roadbed construction filling device described in the present invention, when the retaining plate is opened upward and contacts the cover plate, the retaining plate will be limited by the cover plate, causing a knocking vibration, and the soil placed in the sliding soil mouth will be knocked and fall downward. Through the limiting setting, the soil in the sliding soil mouth will fall onto the conveyor belt or between the conveyor belt and the limiting block. By driving the soil transport motor to drive the conveyor belt to rotate, the soil dropped on the conveyor belt will move along the conveying direction of the conveyor belt to the mud placement area in the soil collecting box, thereby realizing the recovery of the soil.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 11 As shown, a roadbed construction filling device described in an embodiment of the present invention includes a base 1, a rectangular frame 4 is fixedly installed at the bottom of the base 1, a pressure cylinder 2 is rotatably connected to the inner wall of the rectangular frame 4, a cylinder driving motor 201 is fixedly installed at one end of the pressure cylinder 2, a soil collecting box 3 is fixedly installed at the bottom of the base 1, the soil collecting box 3 is placed on one side of the pressure cylinder 2, a cylinder cleaning component is arranged on the outer wall of the pressure cylinder 2, the cylinder cleaning component includes a scraper block 6, the cylinder cleaning component is used to scrape the soil attached to the surface of the pressure cylinder 2 through the scraper block 6, a soil collecting component is arranged inside the soil collecting box 3, the soil collecting component is used to recycle the soil scraped by the cylinder cleaning component, a control cabin 101 is fixedly installed on the top of the base 1, and a tripod 102 is fixedly installed on one side of the base 1;

[0038] When the moisture content of the filled soil is high, its viscosity will increase, and the moisture between the soil particles will act as an adhesive, making it easy for the soil to adhere to the surface of the cylinder. The soil attached to the cylinder will not only affect the compaction of the soil by the cylinder, but also cause a certain amount of resource loss when it is removed.

[0039] During use, the operator enters the control chamber 101 and controls the operation of various parts of the device through the loading system of the control chamber 101, providing a control function for the compaction operation of the device. Then the operator drives the pressure drum 2 to rotate and compact the soil on the roadbed by driving the driving drum motor 201. When the pressure drum 2 rotates and compacts the soil, the cleaning drum component scrapes the surface of the pressure drum 2 through the scraper block 6 to prevent the outer surface of the pressure drum 2 from being attached to the soil, which affects the compaction operation of the pressure drum 2 on the soil laid on the roadbed. At the same time, the soil collecting component in the soil collecting box 3 collects the soil scraped by the scraper block 6 to prevent the soil attached to the pressure drum 2 from being lost during the subsequent cleaning process. Through the cooperation of the cleaning drum component and the soil collecting component, the soil attached to the pressure drum 2 during the soil compaction operation of the pressure drum 2 can be reduced to a certain extent. The impact of the compaction operation caused by the soil attached to the pressure drum 2 can also be concentratedly recovered and reused, thereby reducing the waste of resources and playing a role in soil recycling.

[0040] like Figure 6 to Figure 7 As shown, the cylinder cleaning assembly further includes scraping openings 601, which are opened at both ends of the scraping block 6, and the scraping block 6 is fixedly mounted on the inner wall of the rectangular frame 4. The scraping block 6 is placed directly above the pressing cylinder 2, and the inner wall of the scraping block 6 is slidably connected to the outer surface of the pressing cylinder 2, and the scraping openings 601 are in contact with the outer surface of the pressing cylinder 2;

[0041] When the drum driving motor 201 drives the pressing drum 2 to rotate and compact the soil, the pressing drum 2 is driven to rotate inward during rotation. Through the continuous rotation of the pressing drum 2, the outer wall of the pressing drum 2 will contact the scraper mouth 601, so that the scraper mouth 601 on the scraper block 6 scrapes the surface of the pressing drum 2. When soil is attached to the surface of the pressing drum 2, the scraper mouth 601 scrapes the soil from the outer surface of the pressing drum 2, thereby removing the soil attached to the outer surface of the pressing drum 2, and preventing the pressing drum 2 from being attached to soil. When the pressing drum 2 rotates, the soil drives the remaining soil on the roadbed to cover the outer surface of the pressing drum 2, causing the loss of roadbed soil.

[0042] like Figure 6 to Figure 7 As shown, a hinged rod 901 is fixedly installed on one side of the outer wall of the scraper block 6, and a soil retaining plate 9 is hingedly connected to the outer wall of the hinged rod 901, and a soil sliding opening 902 is opened on the inner wall of the soil retaining plate 9;

[0043] When the scraper 601 scrapes the outer surface of the pressure cylinder 2, the soil has a certain viscosity when the humidity is high. Therefore, when the soil is scraped away from the surface of the pressure cylinder 2 by the scraper 601, the soil scraped away by the scraper 601 will be placed at the angle between the three through the angle limitation among the retaining plate 9, the pressure cylinder 2 and the scraper 601. Through the continuous scraping of the scraper 601 on the outer wall of the pressure cylinder 2, the soil placed at the angle will become more and more, and the soil will slide downward along the sliding mouth 902, so that the soil placed at the angle between the three will slide downward away from the three, thereby preventing the scraped soil from accumulating between the three and affecting the scraping operation of the scraper 601.

[0044] like Figures 3 to 8 As shown, push rods 903 are fixedly installed at both ends of the retaining plate 9, and protrusions 8 are fixedly installed at both ends of the pressing cylinder 2, and the outer walls of the two protrusions 8 can be slidably connected to one side of the two push rods 903 respectively;

[0045] When the pressing cylinder 2 rotates, the pressing cylinder 2 drives the convex block 8 to rotate. When the convex position is set, the convex position will push the push rod 903 to rotate. When the push rod 903 is pushed by the convex position, the position of the retaining plate 9 will change. Through the pushing and squeezing of the convex position 8, the retaining plate 9 will be driven by the push rod 903 to rotate on the hinged rod 901, and the retaining plate 9 will be opened on one side of the scraper block 6 through the hinged rod 901. When the convex position 8 loses contact with the push rod 903, the retaining plate 9 will rotate and reset on the hinged rod 901 by its own weight. Through the continuous rotation of the convex position 8, the retaining plate 9 will reciprocate up and down on the hinged rod 901, thereby realizing the continuous opening and closing of the retaining plate 9 on one side of the scraper block 6 for shaking operation, and the soil placed in the sliding soil mouth 902 will accelerate the downward flow speed driven by its shaking, thereby playing the role of shaking the soil to slide down.

[0046] like Figure 6 to Figure 7 As shown, a cover plate 10 is fixedly mounted on the outer wall of the scraper block 6, and a plurality of soil vibration springs 1001 are arranged between the inner wall of the cover plate 10 and the top of the retaining plate 9;

[0047] When the pressure cylinder 2 pushes the push rod 903 to open the earth retaining plate 9, when the earth retaining plate 9 contacts one end of the cover plate 10, the earth retaining plate 9 stops moving, and the protrusion 8 loses contact with the push rod 903. Through the elastic setting of the vibrating spring 1001, the earth retaining plate 9 will be reset. The pressure cylinder 2 drives the protrusion 8 to rotate continuously, and the protrusion 8 continuously pushes the push rod 903 to hinge open the earth retaining plate 9, and cooperates with the vibrating spring 1001 to push the earth retaining plate 9 to be hinged and reset, thereby realizing the continuous shaking of the earth retaining plate 9. By setting the vibrating spring 1001 to reset the earth retaining plate 9, compared with resetting it by gravity, it can avoid the earth retaining plate 9 being unable to be reset well due to excessive accumulation of soil at the angle limit between the earth retaining plate 9, the pressure cylinder 2 and the scraper 601.

[0048] like Figures 4 to 6 As shown, the soil collecting assembly includes a soil conveying motor 7, which is fixedly mounted on the outer wall of the soil collecting box 3. A conveyor belt 13 is provided inside the soil collecting box 3, and the output end of the soil conveying motor 7 is fixedly connected to the transmission shaft in the conveyor belt 13;

[0049] When the retaining plate 9 opens upward and contacts the cover plate 10, the retaining plate 9 will be limited by the cover plate 10, causing a knocking vibration, and the soil placed in the sliding port 902 will be knocked and fall downward. Through the limiting setting, the soil in the sliding port 902 will fall onto the conveyor belt 13, and the conveyor belt 13 will be driven by the soil transport motor 7 to rotate. The soil that falls on the conveyor belt 13 will move along the conveying direction of the conveyor belt 13 to the mud placement area in the soil collecting box 3, thereby realizing the recovery of the soil.

[0050] like Figures 4 to 6 As shown, a limit block 12 is fixedly installed at the bottom of the inner wall of the soil collecting box 3, and the limit block 12 is placed at the lower side of the pressing cylinder 2. One end of the conveyor belt 13 is placed on one side of the limit block 12 and is slidably connected to the outer wall of the limit block 12. The retaining plate 9 is placed directly above the conveyor belt 13 and the limit block 12.

[0051] Since the limit block 12 is placed on the lower side of the pressing cylinder 2, when the pressing cylinder 2 rotates, the center position of the pressing cylinder 2 should be placed on the inner side of the limit block 12. Through its continuous rotation, the soil can be prevented from falling from the gap between the pressing cylinder 2 and the limit block 12 to the outside of the device. The setting of the limit block 12 plays a limiting role.

[0052] like Figures 6 to 11As shown, a scraper plate 14 is fixedly installed inside the soil collecting box 3, and the top of the scraper plate 14 is slidably connected to the outer wall of the conveyor belt 13. A plurality of water leakage holes 301 are opened on the inner wall of the soil collecting box 3. A water-absorbing cotton board 15 is fixedly installed on the inner wall of the soil collecting box 3. The water-absorbing cotton board 15 is placed above the plurality of water leakage holes 301, and the outer wall of the scraper plate 14 is fixedly connected to one side of the water-absorbing cotton board 15.

[0053] When the conveyor belt 13 drives the soil into the mud placement area, the scraper plate 14 scrapes the outer wall of the conveyor belt 13, thereby scraping the soil retained on the conveyor belt 13 into the mud placement area, playing the role of scraping the soil off the surface of the conveyor belt 13. When the soil is retained in the mud placement area in the soil collecting box 3, the soil will be placed on the top of the absorbent cotton board 15. Through the water absorption characteristics of the absorbent cotton board 15, the absorbent cotton board 15 will absorb the moisture in the soil, thereby reducing the humidity of the soil, which is conducive to its subsequent recycling. The leakage port 301 is opened to facilitate the outflow of water absorbed in the absorbent cotton board 15, playing the role of water outlet.

[0054] like Figures 6 to 9 As shown, the outer wall of the soil collecting box 3 is fixedly installed with an electric guide rail 11, the inner wall of the electric guide rail 11 is slidably connected with an electric slider 1101, one end of the electric slider 1101 is fixedly installed with a connecting block 1103, one end of the connecting block 1103 is fixedly installed with a bulldozer 1102, the outer walls of the connecting block 1103 and the bulldozer 1102 are slidably connected to the inner wall of the soil collecting box 3, and the outer wall of the bulldozer 1102 is slidably connected to the outer walls of the absorbent cotton board 15 and the scraper board 14;

[0055] When the compaction operation is completed, the electric slider 1101 is driven to slide in the electric guide rail 11. When the electric slider 1101 slides in the electric guide rail 11, the electric slider 1101 drives the bulldozer 1102 to slide in the mud placement area in the soil collecting box 3 through the connecting block 1103, thereby pushing the soil placed on the top of the absorbent cotton board 15, so that the soil is pushed out of the soil collecting box 3, which plays the role of taking out the soil and is convenient for subsequent recycling.

[0056] like Figures 9 and 10 As shown, a limit plate 502 is fixedly installed on one side of the soil collecting box 3, a blocking plate 5 is hingedly connected to one side of the soil collecting box 3, the limit plate 502 is placed outside the blocking plate 5, and a return spring 501 is directly provided on one side of the blocking plate 5 and the limit plate 502;

[0057] When the electric slider 1101 drives the bulldozer plate 1102 to push the soil, the blocking plate 5 will be pushed open on one side of the soil collecting box 3 by the thrust, and the soil placed in the built-in mud area of ​​the soil collecting box 3 will be pushed out of the device from the blocking plate 5 by the bulldozer plate 1102. When the bulldozer plate 1102 completely pushes the soil in the mud placing area, the electric slider 1101 drives it to reset, and under the elastic push of the reset spring 501, the blocking plate 5 will reset, thereby blocking the opening to prevent the soil from flowing out of the blocking plate 5 when the soil is recovered, thereby playing a role in blocking the outflow of soil.

[0058] Working principle: when in use, the operator enters the control chamber 101 and controls the operation of various parts of the device through the loading system of the control chamber 101, providing control for the compaction operation of the device, and then the operator drives the pressure drum 2 to rotate and compact the soil on the roadbed by driving the driving drum motor 201. When the pressure drum 2 rotates and compacts the soil, the cleaning drum component scrapes the surface of the pressure drum 2 through the scraper block 6 to prevent the outer surface of the pressure drum 2 from being attached to the soil, which affects the compaction operation of the pressure drum 2 on the soil laid on the roadbed. At the same time, the soil collecting component in the soil collecting box 3 collects the soil scraped by the scraper block 6 to prevent the soil attached to the pressure drum 2 from being lost during the subsequent cleaning process. The cleaning drum component and the soil collecting component cooperate with each other to reduce the impact of the soil attached to the pressure drum 2 on the compaction operation when the pressure drum 2 is compacting the soil. At the same time, the attached soil can be collected and reused, which reduces the waste of resources and plays a role in soil recycling.

[0059] When the drum driving motor 201 drives the pressing drum 2 to rotate and compact the soil, the pressing drum 2 is driven to rotate inward during the rotation. Through the continuous rotation of the pressing drum 2, the outer wall of the pressing drum 2 will contact the scraping mouth 601, so that the scraping mouth 601 on the scraper block 6 scrapes the surface of the pressing drum 2. When the surface of the pressing drum 2 is adhered to soil, the scraping mouth 601 scrapes the soil from the outer surface of the pressing drum 2, thereby removing the soil adhered to the outer surface of the pressing drum 2, and preventing the pressing drum 2 from adhering to soil. When the pressing drum 2 is rotated, the soil drives the remaining soil on the roadbed to cover the outer surface of the pressing drum 2, resulting in the loss of roadbed soil.

[0060] When the scraper 601 scrapes the outer surface of the pressure cylinder 2, the soil has a certain viscosity when the humidity is high. Therefore, when the soil is scraped by the scraper 601 and leaves the surface of the pressure cylinder 2, the soil scraped by the scraper 601 will be placed at the angle between the three through the angle limit between the retaining plate 9, the pressure cylinder 2 and the scraper 601. Through the continuous scraping of the outer wall of the pressure cylinder 2 by the scraper 601, the soil placed at the angle will become more and more, and the soil will slide downward along the soil sliding port 902, so that the soil placed at the angle between the three will slide downward away from the three, thereby preventing the scraped soil from accumulating between the three and affecting the scraping operation of the scraper 601.

[0061] When the pressing cylinder 2 rotates, the pressing cylinder 2 drives the convex block 8 to rotate. When the convex block 8 rotates, the convex position setting causes the convex block 8 to push the push rod 903 to rotate. When the push rod 903 is pushed by the convex position, the position of the retaining plate 9 will change. Through the pushing and squeezing of the convex block 8, the retaining plate 9 will be driven by the push rod 903 to rotate on the hinged rod 901, and the retaining plate 9 will be opened on one side of the scraper block 6 through the hinged rod 901. When the convex block 8 loses contact with the push rod 903, the retaining plate 9 will rotate and reset on the hinged rod 901 by its own weight. Through the continuous rotation of the convex block 8, the retaining plate 9 will reciprocate up and down on the hinged rod 901. The retaining plate 9 is continuously opened and closed on one side of the scraper block 6 for shaking operation, and the soil placed in the sliding soil port 902 will accelerate the speed of downward flow driven by its shaking, thereby playing the role of shaking the soil to slide down;

[0062] When the pressure cylinder 2 pushes the push rod 903 to open the retaining plate 9, when the retaining plate 9 contacts one end of the cover plate 10, the retaining plate 9 stops moving, and the protrusion 8 loses contact with the push rod 903. The retaining plate 9 is reset by the elastic setting of the soil vibration spring 1001, and the protrusion 8 is driven by the pressure cylinder 2 to rotate continuously. The protrusion 8 continuously pushes the push rod 903 to hinge the retaining plate 9 open, and the soil vibration spring 1001 pushes the retaining plate 9 to be hinged and reset, thereby realizing the continuous shaking of the retaining plate 9. By setting the soil vibration spring 1001 to reset the retaining plate 9, compared with resetting it by gravity, it can be avoided that the retaining plate 9 cannot be reset well due to excessive accumulation of soil at the angle limit between the retaining plate 9, the pressure cylinder 2 and the scraper 601;

[0063] When the retaining plate 9 opens upward and contacts the cover plate 10, the retaining plate 9 will be limited by the cover plate 10, causing a knocking vibration, and the soil placed in the sliding soil opening 902 will be knocked down and fall down. Through the limit setting, the soil in the sliding soil opening 902 will fall onto the conveyor belt 13, and the conveyor belt 13 will be driven to rotate by the soil transport motor 7. The soil falling on the conveyor belt 13 will move along the conveying direction of the conveyor belt 13 to the mud placement area in the soil collecting box 3, thereby realizing the recovery of the soil;

[0064] Since the limit block 12 is placed at the lower side of the pressing cylinder 2, when the pressing cylinder 2 rotates, the center position of the pressing cylinder 2 should be placed inside the limit block 12. Through its continuous rotation, it can prevent the soil from falling from the gap between the pressing cylinder 2 and the limit block 12 to the outside of the device. The setting of the limit block 12 plays a role of limiting.

[0065] When the conveyor belt 13 drives the soil into the mud placement area, the scraper plate 14 scrapes the outer wall of the conveyor belt 13, thereby scraping the soil retained on the conveyor belt 13 into the mud placement area, playing the role of scraping the soil off the surface of the conveyor belt 13. When the soil is retained in the mud placement area in the soil collecting box 3, the soil will be placed on the top of the absorbent cotton board 15. Through the water absorption characteristics of the absorbent cotton board 15, the absorbent cotton board 15 will absorb the moisture in the soil, thereby reducing the humidity of the soil, which is conducive to its subsequent recycling. The water leakage port 301 is opened to facilitate the outflow of the water absorbed in the absorbent cotton board 15, playing the role of water outlet;

[0066] When the compaction operation is completed, the electric slider 1101 is driven to slide in the electric guide rail 11. When the electric slider 1101 slides in the electric guide rail 11, the electric slider 1101 drives the bulldozer 1102 to slide in the mud placement area in the soil collecting box 3 through the connecting block 1103, thereby pushing the mud placed on the top of the absorbent cotton board 15, so that the mud is pushed out of the soil collecting box 3, which plays the role of taking out the mud and is convenient for subsequent recycling;

[0067] When the electric slider 1101 drives the bulldozer plate 1102 to push the soil, the blocking plate 5 will be pushed open on one side of the soil collecting box 3 by the thrust, and the soil placed in the built-in mud area of ​​the soil collecting box 3 will be pushed out of the device from the blocking plate 5 by the bulldozer plate 1102. When the bulldozer plate 1102 completely pushes the soil in the mud placing area, the electric slider 1101 drives it to reset, and under the elastic push of the reset spring 501, the blocking plate 5 will reset, thereby blocking the opening to prevent the soil from flowing out of the blocking plate 5 when the soil is recovered, thereby playing a role in blocking the outflow of soil.
