Abstract
Description
Technical Field
[0001] This utility model relates to the field of road repair technology, and in particular to a road surface grinding device for road repair. Background Technology
[0002] In road repair projects, grinding is an efficient and precise repair process that facilitates the removal of protruding defects on the road surface, ensuring a smooth road surface.
[0003] A search revealed that the Chinese patent "A Concrete Road Grinding Device" (authorization announcement number CN221142400U) includes tires, a dust removal mechanism, and a lifting mechanism. By installing the lifting and dust removal mechanisms, upon reaching the work site, a sealing plate is lowered to contact the concrete road surface, thereby sealing the grinding area and reducing noise during grinding. However, this method has the following drawbacks in practical use: During grinding, the sealing plate needs to be in close contact with the road surface, making it difficult to perform walking-type grinding, resulting in low grinding efficiency. Furthermore, the use of pipes for dual-point dust removal in the grinding area has a poor adsorption range, leading to low dust collection efficiency and the potential for dead zones. Utility Model Content
[0004] Therefore, it is necessary to provide a road surface grinding device for road repair that addresses the problems of difficult walking grinding, low dust collection efficiency, and the presence of blind spots in dust collection.
[0005] A road surface grinding device for road repair includes a frame and a grinding disc disposed at its bottom; it also includes a dust removal mechanism disposed on the outside of the grinding disc and used to adsorb and treat the dust generated during the operation of the grinding disc; wherein, the dust removal mechanism includes a dust suction hopper and a collar sleeved to its outside, the dust suction hopper is provided with a set of dust suction pipes inside, the dust suction pipes are evenly distributed along the axis of the dust suction hopper, and an annular groove is opened on one side of the collar, the opening of the annular groove is inclined towards the axis of the collar.
[0006] In one embodiment, the dust collection hopper is installed inside the frame, and a rubber sleeve is fitted on the outer side of the collar.
[0007] In one embodiment, the dust collection hopper has a set of annularly distributed sound-absorbing grooves inside, and the sound-absorbing grooves are inclined.
[0008] In one embodiment, the frame is provided with an inner ring pipe and an outer ring pipe, one end of the suction pipe is connected to the inner ring pipe, and a set of vertical pipes is provided between the outer ring pipe and the annular groove.
[0009] In one embodiment, a dust collection box is provided on the outside of the frame, and an air pump is provided inside the dust collection box. Both the output and input ends of the air pump are equipped with conduits. One end of one of the conduits is connected to an outer ring pipe, and a horizontal pipe connected to the dust collection box is installed on the inner ring pipe.
[0010] In one embodiment, a filter plate is provided on the outer side of the end of the horizontal pipe, and the filter plate is angled and installed inside the dust collection box.
[0011] In one embodiment, a set of casters is provided below the frame, and the casters are at the same level as the bottom of the rubber sleeve.
[0012] Beneficial effects
[0013] 1. By setting up a collar, when performing multi-point vacuuming, the annular groove inside the collar can be used to discharge gas, forming an annular air curtain on the outside of the polishing area. This air curtain can be used to block dust and reduce dust leakage. At the same time, the gas can drive the dust to move towards the center of the polishing area, reducing the phenomenon of dust spreading outward, ensuring vacuuming efficiency, and reducing vacuuming dead corners.
[0014] 2. By setting a rubber sleeve, the grinding area can be covered to block dust and reduce noise. It also has good wear resistance when in contact with the road surface, making it convenient for users to perform continuous grinding at fixed points and continuous grinding while walking, thus improving grinding efficiency.

[0027] The following is combined Figures 1-4 This invention describes a road surface grinding device for road repair.
[0028] In one embodiment, a road surface grinding device for road repair includes a frame 100 and a grinding disc 200 disposed at its bottom; it also includes a dust removal mechanism 300 disposed on the outside of the grinding disc 200 and used to adsorb and treat the dust generated during the operation of the grinding disc 200; wherein, the dust removal mechanism 300 includes a dust suction hopper 310 and a collar 320 sleeved on its outside, the dust suction hopper 310 is provided with a set of dust suction pipes 311 inside, the dust suction pipes 311 are evenly distributed along the axis of the dust suction hopper 310, and an annular groove 321 is opened on one side of the collar 320, the opening of the annular groove 321 is inclined toward the axis of the collar 320.
[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the dust collection hopper 310 is installed inside the frame 100, and a rubber sleeve 322 is fitted on the outside of the collar 320.
[0030] In this embodiment, during the grinding operation, the grinding disc 200 rotates at high speed and contacts the road surface. At this time, the dust collection bucket 310 and the dust collection pipe 311 are used to perform multi-point dust collection on the grinding area, and the gas is discharged along the annular groove 321 to the grinding area, so that the gas covers the grinding area in an annular shape. On the one hand, the dust is blocked and guided to reduce the occurrence of dust leakage, and the dust is brought closer to the center of the grinding area, which is convenient for the dust collection pipe 311 to fully absorb it. On the other hand, the annular air curtain formed can weaken the noise generated during grinding and reduce its propagation range. With the setting of the rubber sleeve 322, it has good wear resistance and can use its side to rub against the road surface, which has a combined effect of dust blocking and noise reduction, and does not affect the frame 100 to drive the grinding disc 200 to carry out walking operation.
[0031] It should be noted that the rubber sleeve 322 is a detachable design, and users can replace it periodically according to the wear condition;
[0032] The frame 100 is equipped with a servo motor that interfaces with the grinding disc 200, and has two electric push rods for driving the servo motor and adjusting the height of the grinding disc 200, which are used according to grinding needs. The frame 100 is equipped with a set of heat dissipation holes to ensure a good working environment for the electric push rods and servo motor.
[0033] like Figure 2 and Figure 3 As shown, the dust collection hopper 310 has a set of annularly distributed sound-absorbing grooves 312 inside, and the sound-absorbing grooves 312 are inclined.
[0034] By using the noise reduction groove 312, some of the noise generated in the grinding area can be directed into the noise reduction groove 312, causing it to be reflected within the noise reduction groove 312, extending the noise propagation path, and achieving the noise reduction effect.
[0035] like Figure 2 and Figure 4 As shown, the frame 100 is equipped with an inner ring pipe 110 and an outer ring pipe 120. One end of the suction pipe 311 is connected to the inner ring pipe 110, and a set of vertical pipes is provided between the outer ring pipe 120 and the annular groove 321.
[0036] The inner ring pipe 110 is used in conjunction with the suction pipe 311 for vacuuming and dust extraction, and the outer ring pipe 120 is used in conjunction with the riser for exhaust.
[0037] like Figure 2 As shown, a dust collection box 130 is provided on the outside of the frame 100, and an air pump 131 is provided inside the dust collection box 130. Both the output and input ends of the air pump 131 are equipped with conduits. One end of one of the conduits is connected to the outer ring pipe 120, and a horizontal pipe connected to the dust collection box 130 is installed on the inner ring pipe 110.
[0038] The air pump 131 operates to create a negative pressure inside the horizontal pipe, so that the dust suction pipe 311, which is connected to the inner ring pipe 110, will suck up the dust into the dust collection box 130. Then, the extracted gas is introduced into the outer ring pipe 120 through the corresponding conduit for discharge.
[0039] like Figure 2 As shown, a filter plate is provided on the outer side of the end of the horizontal pipe. The filter plate is folded and installed inside the dust collection box 130.
[0040] The filter plate is used to centrally intercept the adsorbed dust, reducing the cleaning difficulty for users;
[0041] It should be noted that an opening and closing door is provided on the outside of the dust collection box 130, which users can open periodically to collect and dispose of the dust inside.
[0042] like Figure 1 and Figure 2As shown, a set of casters is provided below the frame 100, and the casters are at the same level as the bottom of the rubber sleeve 322.
[0043] The rubber sleeve 322 is used to maintain continuous contact with the road surface, thereby ensuring its dustproof and sound insulation effects.
[0044] Working principle: The user pushes the frame 100 using the handle and casters. When grinding is required, the electric push rod drives the grinding disc 200 to contact the ground. Then, the servo motor is started, causing the grinding disc 200 to rotate at high speed for grinding. During the grinding process, the air pump 131 is started, and the multi-point suction pipe 311 performs dust suction. At the same time, the annular groove 321 continuously discharges air along the ring, covering the grinding area for dust blocking and noise reduction. Then, the filter plate is used to collect and intercept the adsorbed dust. After the grinding is completed, the air pump 131 and servo motor can be stopped, the grinding disc 200 can be reset, and then the dust in the dust collection box 130 can be cleaned.
[0045] It should be noted that the air pump 131, servo motor, electric actuator, etc. mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the air pump 131, servo motor, and electric actuator can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
