A compactor for road repair

Abstract

The present invention relates to the technical field of engineering machinery, and specifically to a compactor for highway repair, which includes a pressure plate, a blocking net, a sensing member and an adjusting member. In an initial state, the blocking net is not blocked by dust. As the pressure plate hammers the roadbed, the blocking net is gradually blocked by dust. The sensing member can sense the degree of blockage of the blocking net. The adjusting member can combine the data sensed by the sensing member, manually or mechanically move the adjustment rod, and then pull the blocking net upward through the adjustment block to adjust the blocking net from a wrinkled first state to a smooth second state. When the engine is running, the oscillation of the pressure plate can drive the blocking net to oscillate synchronously, and the dust attached to the blocking net can break away from the blocking net. When the blocking net is transformed into the second state, the dust blocking the blocking net is more likely to break away from the blocking net, thereby achieving cleaning of the blocking net and continuously preventing dust and stones from falling on the pressure plate, thereby improving the construction efficiency of the pressure plate.

Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, in particular to a compactor for road repair. Background Art

[0002] Roadbed maintenance is crucial in highway construction, with its quality directly impacting the overall performance and service life of the road. Plate compactors, commonly used for roadbed maintenance, currently rely primarily on vibration to compact the subgrade. During the compaction operation, dust and gravel from the road surface inevitably accumulate on the platen. As the platen vibrates, this accumulated dust generates a large amount of fugitive dust, which pollutes the construction site and surrounding environment, reducing air quality. Furthermore, dust can enter the platen's engine intake system, rapidly clogging the engine filter. Frequent filter replacement is necessary to ensure proper engine operation, increasing the labor, material, and time costs of equipment maintenance and reducing construction efficiency.

[0003] At the same time, the continuous friction between hard objects such as stones and the upper surface of the pressure plate will cause wear on the upper surface of the pressure plate. As the wear on the surface of the pressure plate increases, the compaction effect of the pressure plate will gradually decrease, affecting the compaction quality of the roadbed and even shortening the service life of the flat plate compactor, increasing the frequency and cost of equipment replacement; in addition, a large amount of noise will be generated during the vibration of the stones on the pressure plate, and the noise generated will easily have an adverse effect on the surrounding sound environment.

In the initial state, the slider is at the lower end of the sliding groove.

[0010] Furthermore, the adjustment part includes an adjustment rod and a transmission rod, the transmission rod is fixedly connected to the sensing plate; one end of the adjustment rod is fixedly connected to the transmission rod, and the middle part of the adjustment rod is rotatably connected to the shielding cover; an adjustment groove is provided at one end of the adjustment rod away from the transmission rod, and an adjustment block is fixedly provided on the sliding ring, and the adjustment block can slide and rotate in the adjustment groove.

[0011] Furthermore, there are two adjustment rods, which are distributed on both sides of the shielding cover. The two adjustment rods are respectively fixedly connected to the two ends of the transmission rod. Two adjustment blocks are fixedly provided on the sliding ring, and each adjustment block can slide and rotate in one of the adjustment slots.

[0012] Furthermore, the sliding ring has a preset weight.

[0013] Furthermore, the engine has an intake pipe and an exhaust pipe, the intake pipe passes through the shielding cover, the axial direction of the end of the intake pipe is perpendicular to the axial direction of the air outlet, and the axial direction of the end of the intake pipe is in the same plane as the axial direction of the air outlet; the intake pipe is arranged above the air outlet; the exhaust pipe passes through the shielding cover.

[0014] Furthermore, a humidifier is provided on the shielding cover, and the humidifier can humidify the barrier net.

[0015] Furthermore, the humidifier is capable of spraying water toward one side of the pressing plate.

[0017] The beneficial effects of the present invention are as follows: the present invention is a rammer for road repair, which includes a pressure plate, a blocking net, a sensing element and an adjusting element. During roadbed maintenance, the pressure plate is moved onto the roadbed, and the engine is started. The engine can drive the pressure plate to hammer the roadbed. In the initial state, the blocking net is in a state of blocking the air inlet, and the blocking net is in a first wrinkled state. The blocking net blocks the dust generated during the hammering of the pressure plate to prevent dust and stones from falling onto the pressure plate.

When the engine is running, the oscillation of the pressure plate can drive the barrier net to oscillate synchronously. During the oscillation of the barrier net, the dust attached to the barrier net can be separated from the barrier net. When the barrier net is transformed into the second state, since the barrier net is in a straight state compared to the first state, the vibration of the pressure plate is more likely to spread on the barrier net, and the dust blocking the barrier net is more likely to be separated from the barrier net, thereby achieving the cleaning of the barrier net and realizing The present invention continuously prevents dust and stones from falling on the pressure plate, thereby improving the construction efficiency of the pressure plate; that is, the present invention can use a blocking net to block the air inlet between the shielding cover and the pressure plate to prevent dust, stones, etc. from falling on the pressure plate, and can also pass the preliminary filtration of the blocking net to deliver clean air to the engine through the intake pipe, avoiding rapid clogging of the engine filter element and ensuring the normal operation of the engine, and further, the blocking net is set to a first and a second state. That is, at the initial stage, the blocking net is in a pleated state and can still ensure the interception of dust and stones, and at the same time can ensure a certain degree of air filtration, but the effect gradually becomes worse. As more dust and other particles adhere to the barrier net, under the oscillation of the pressure plate, the dust will float in the space formed by the shielding cover, the barrier net, and the pressure plate, and the air delivered to the engine through the intake pipe will naturally no longer be clean. Therefore, the adjustment lever is manually or mechanically toggled, and the barrier net is pulled upward through the adjustment block to switch the barrier net to the second state. Under the oscillation of the pressure plate, dust and other impurities on the barrier net can be quickly shaken off, and continue to play an efficient interception and filtration function, thereby continuously preventing dust and stones from falling on the pressure plate, while providing clean air for the engine and improving the overall working efficiency of the structure.

[0029] like Figures 1 to 6 As shown, an embodiment of the present invention provides a compactor for road repair, which includes a pressing plate 110, a blocking net 140, a sensing part and an adjusting part.

[0030] The pressing plate 110 is arranged horizontally and has an upper end surface and a lower end surface. The lower end surface of the pressing plate 110 can directly contact the roadbed. A mounting frame 111 is fixedly provided on the upper end surface of the pressing plate 110. An engine 120 is fixedly provided on the mounting frame 111. A rotatable flywheel is provided on the upper end surface of the pressing plate 110. The engine 120 can drive the flywheel to rotate. When the flywheel rotates, the flywheel can drive the pressing plate 110 to oscillate on the roadbed, thereby achieving hammering and compacting of the roadbed by the pressing plate 110. A shielding cover 130 is fixedly provided on the mounting frame 111. The shielding cover 130 is spaced apart from the pressing plate 110. An air inlet is provided between the shielding cover 130 and the pressing plate 110. The shielding cover 130 is a cavity with an opening facing downward.

[0031] The blocking net 140 is in a circular shape and is mounted on the outside of the shielding cover 130. The blocking net 140 can block the air inlet. The upper end of the blocking net 140 is connected to the shielding cover 130, and the lower end of the blocking net 140 is connected to the pressure plate 110. The blocking net 140 is made of non-woven fabric and has multiple small holes to ensure that the gas in the external environment can enter the inside of the shielding cover through the air inlet. The blocking net 140 has a first wrinkled state and a second smooth state in the vertical direction. The dust and stones generated when the pressure plate 110 oscillates on the roadbed can be intercepted by the blocking net 140, thereby preventing dust and stones from falling on the upper end surface of the pressure plate 110. The barrier net 140 is initially in a first, wrinkled state, with some overlap. As it transitions from the first to the second state, it gradually straightens. During this process, the net 140 undergoes a flattening oscillation, allowing dust adhering to the net 140 to be shaken free. In the initial state, the pores on the surface of the net 140 are not clogged with dust. As the pressure plate 110 oscillates on the roadbed, it drives the net 140 in sync, causing dust to oscillate and fall off. In the second state, the net 140 is more straightened than in the first state. The oscillation of the pressure plate 110 facilitates vibration propagation through the net 140, allowing dust clogged with the net 140 to escape more easily.

[0032] The sensing element is used to sense the degree of blockage of the blocking net 140. As the pressure plate 110 hammers the roadbed, the degree to which the blocking net 140 is blocked by dust gradually increases. In this embodiment, the sensing element is a visual sensor. In the initial state, the weaving contour of the blocking net 140 is clear, and the visual sensor can clearly observe the weaving contour of the blocking net 140. As dust gradually adheres to the blocking net 140, the visual sensor can observe that the weaving contour of the blocking net 140 is gradually rounded. The degree of blockage of the blocking net 140 is determined based on the degree of roundness of the weaving contour of the blocking net 140.

[0033] The adjusting member is used to adjust the blocking net 140 between the first state and the second state according to the data of the sensing member. Specifically, in the initial state, the blocking net 140 is in a clean state, and the blocking net 140 is in the first state. As the blocking net 140 is gradually clogged with dust, the blocking net 140 gradually changes from the first state to the second state, and the blocking net 140 oscillates to flatten, and the dust attached to the blocking net 140 can be oscillated away from the blocking net 140. Furthermore, when the engine 120 is running, the oscillation of the pressure plate 110 can drive the blocking net 140 to oscillate synchronously. During the oscillation of the blocking net 140, the dust attached to the blocking net 140 can be separated from the blocking net 140. When the blocking net 140 changes to the second state, the dust blocking the blocking net 140 is more easily separated from the blocking net 140, thereby achieving the cleaning of the blocking net 140 and continuously preventing dust and stones from falling on the pressure plate 110, thereby improving the construction efficiency of the pressure plate 110.

[0034] The present invention relates to a rammer for road repair. During roadbed maintenance, the pressing plate 110 is moved onto the roadbed, and the engine 120 is started. The engine 120 can drive the pressing plate 110 to hammer the roadbed. In the initial state, the blocking net 140 is in a wrinkled first state. The blocking net 140 blocks the dust generated during the hammering of the pressing plate 110 to prevent dust and stones from falling on the pressing plate 110. In the initial state, the blocking net 140 is not blocked by dust. As the pressing plate 110 hammers the roadbed, the blocking net 140 is gradually blocked by dust. The sensor can sense the degree of blockage of the blocking net 140, and the adjustment part can adjust the blockage by hand in combination with the data sensed by the sensor. The adjusting rod 240 is manually or mechanically moved, and the blocking net 140 is pulled upward through the adjusting block 260 to adjust the blocking net 140 from the wrinkled first state to the smooth second state. When the engine 120 is running, the oscillation of the pressure plate 110 can drive the blocking net 140 to oscillate synchronously. During the oscillation of the blocking net 140, the dust attached to the blocking net 140 can be separated from the blocking net 140. When the blocking net 140 is transformed into the second state, the dust blocking the blocking net 140 is more easily separated from the blocking net 140, thereby achieving the cleaning of the blocking net 140 and continuously preventing dust and stones from falling on the pressure plate 110, thereby improving the construction efficiency of the pressure plate 110.

[0035] In one embodiment, the sensing element includes an air pump 210 and an induction plate 220. The air pump 210 is fixedly mounted on the shielding cover 130. The air pump 210 has an air inlet and an air outlet 212. The air inlet extends to the inside of the shielding cover 130, and the air outlet 212 is connected to the external environment. Specifically, under the action of the blocking net 140, the inside of the shielding cover 130 is in a relatively closed state. If the gas from the external environment wants to enter the inside of the shielding cover 130, the gas from the external environment needs to be filtered by the blocking net 140. The air pump 210 is arranged outside the shielding cover 130. When the air pump 210 is started, the air pump 210 extracts the gas inside the shielding cover 130 through the air inlet, and then the gas is discharged into the external environment through the air outlet 212 of the air pump 210. The sensing plate 220 is connected to the shielding cover 130. The sensing plate 220 can swing on the shielding cover 130. The gas discharged from the air outlet 212 can directly act on the sensing plate 220. The gas discharged from the air outlet 212 can blow the sensing plate 220, causing the sensing plate 220 to swing on the shielding cover 130. When the pressure of the gas blown out from the air outlet 212 is different, the degree of blockage of the blocking net 140 is different, and the swinging amplitude of the sensing plate 220 on the shielding cover 130 is different. In the initial state, the degree of blockage of the blocking net 140 is at the lowest state, and the swinging amplitude of the sensing plate 220 on the shielding cover 130 is at the maximum state. As the dust blocks the blocking net 140, the swinging amplitude of the sensing plate 220 on the shielding cover 130 gradually decreases. The staff judges the degree of blockage of the blocking net 140 by the dust by the swinging amplitude of the sensing plate 220 on the shielding cover 130.

[0036] In one embodiment, a sliding ring 230 is fixedly provided on the upper end of the blocking net 140, and the sliding ring 230 is always in contact with the side wall of the blocking net 140, and the lower end of the blocking net 140 is fixedly connected to the pressure plate 110; the sliding ring 230 is slidably connected to the shielding cover 130. Specifically, a sliding groove is provided on the shielding cover 130, and the sliding groove is vertically arranged. A slider is fixedly provided on the sliding ring 230, and the slider is slidably arranged in the sliding groove. In the initial state, the slider is at the lower end of the sliding groove, so that the blocking net 140 is in a wrinkled first state. When the degree of blockage of the blocking net 140 gradually increases, the adjusting rod 240 is manually or mechanically toggled, and then the slider on the sliding ring 230 gradually slides upward along the sliding groove. In the process of the sliding ring 230 sliding upward, the blocking net 140 gradually changes from the wrinkled first state to the smooth second state.

[0037] In one embodiment, the adjustment member includes an adjustment rod 240 and a transmission rod 250. The transmission rod 250 is fixedly connected to the sensing plate 220. One end of the adjustment rod 240 is fixedly connected to the transmission rod 250. Specifically, the end of the adjustment rod 240 is fixedly connected to the end of the transmission rod 250. The middle portion of the adjustment rod 240 is rotatably connected to the outer wall of the shielding cover 130. The adjustment rod 240 and the transmission rod 250 provide a mounting base for the sensing plate 220. An adjustment slot 241 is provided at the end of the adjustment rod 240 away from the transmission rod 250. The adjustment slot 241 extends along the length of the adjustment rod 240. An adjustment block 260 is fixedly mounted on the sliding ring 230. One end of the adjustment block 260 can slide and rotate within the adjustment slot 241. When the adjustment rod 240 rotates on the outer wall of the shielding cover 130, the adjustment rod 240 can pull the adjustment block 260 to move vertically, thereby causing the sliding ring 230 to move up and down on the outer wall of the shielding cover 130.

[0038] In one embodiment, two adjustment rods 240 are provided, and the two adjustment rods 240 have the same length. The two adjustment rods 240 are distributed on both sides of the shielding cover 130. The two adjustment rods 240 are fixedly connected to the two ends of the transmission rod 250 respectively. The two adjustment rods 240 are parallel to each other. The middle parts of the two adjustment rods 240 rotate simultaneously to connect the outer wall of the shielding cover 130. The rotating shafts of the two adjustment rods 240 connected to the shielding cover 130 are on the same straight line. Two adjustment blocks 260 are fixedly provided on the sliding ring 230. The two adjustment blocks 260 are distributed on both sides of the shielding cover 130. Each adjustment block 260 corresponds to an adjustment rod 240, and each adjustment block 260 can slide and rotate in an adjustment groove 241. By setting two adjustment rods 240 and two adjustment blocks 260, when the gas discharged from the air outlet 212 of the vacuum pump 210 acts on the induction plate 220, the two adjustment rods 240 are driven by the transmission rod 250, so that the two adjustment rods 240 rotate synchronously on the outer wall of the shielding cover 130. The two adjustment rods 240 can pull the two adjustment blocks 260 to move in the vertical direction, thereby allowing the sliding ring 230 to move smoothly on the outer wall of the shielding cover 130.

[0039] In one embodiment, the sliding ring 230 has a preset weight. In the initial state, the sliding ring 230 is subjected to its own gravity, so that the slider on the sliding ring 230 is at the lower end of the slide groove, thereby ensuring that the barrier net 140 is in the first wrinkled state in the initial state.

[0040] In one embodiment, the engine 120 has an intake pipe 121 and an exhaust pipe 122. The intake pipe 121 passes through the shielding cover 130 and is connected to the external environment. The axial direction of the end of the intake pipe 121 is perpendicular to the axial direction of the air outlet 212, and the axial direction of the end of the intake pipe 121 and the axial direction of the air outlet 212 are in the same vertical plane. The intake pipe 121 is arranged above the air outlet 212. Specifically, the air outlet 212 of the air pump 210 is arranged vertically, and the axial direction of the end of the intake pipe 121 is arranged horizontally. The intake pipe 121 and the air outlet 212 of the air pump 210 are in the same vertical plane. 121 is disposed above the air outlet 212 of the air pump 210. When the air outlet 212 of the air pump 210 discharges air, the exhaust gas discharged from the air outlet 212 can enter the interior of the air intake pipe 121, providing clean air for the engine 120. At the same time, when the gas discharged from the air outlet 212 is blown toward the air intake pipe 121, the flowing gas can intercept dust around the air intake pipe 121, thereby preventing dust around the air intake pipe 121 from entering the interior of the air intake pipe 121. The exhaust pipe 122 passes through the shielding cover 130, and the exhaust gas generated by the engine 120 during operation is discharged into the external environment through the exhaust pipe 122.

[0041] In one embodiment, a humidifier 310 is provided on the shielding cover 130. The humidifier 310 can humidify the blocking net 140 through multiple nozzles extending to the vicinity of the blocking net 140. When the blocking net 140 is in a wet state, when the vacuum pump 210 is started, dust in the external environment adheres to the blocking net 140, and the dust is likely to clump on the blocking net 140. When the pressure plate 110 drives the blocking net 140 to oscillate synchronously, the clumped dust is more likely to break away from the blocking net 140.

[0042] In one embodiment, the humidifier 310 can spray water toward one side of the pressure plate 110 through multiple nozzles extending near the barrier net 140. After the humidifier 310 sprays water toward one side of the pressure plate 110, the dust on the roadbed is reduced from floating into the air environment during the hammering of the roadbed by the pressure plate 110.

[0043] In one embodiment, a handle 320 is provided on the shielding cover 130 , and when the worker is hammering the roadbed, the worker can guide the pressing plate 110 through the handle 320 to ensure that the pressing plate 110 hammers the roadbed in a specific area.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
