Description

Technical Field

[0001] This application belongs to the field of grooving machine technology, and particularly relates to a road grooving machine. Background Technology

[0002] Road grooving machines are widely used in road maintenance, pipeline laying, and other projects. When they groove the road surface using cutting wheels, they generate a large amount of dust. Current technology typically equips grooving machines with dust collection systems to reduce dust pollution. For example, a dust collection bucket, suction pipe, and suction fan work together to draw dust from the cutting area into a dust collection box. However, these dust collection systems generally suffer from low absorption efficiency and incomplete dust control.

[0003] Traditional dustbins often use a fixed structure, which can only cover a local area of ​​the cutting wheel. This means that the dust generated during the cutting process cannot be fully captured. In addition, the airflow generated by the rotating cutting wheel will cause the dust to spread in all directions, causing fine dust to escape from the edges of the dustbin. At the same time, the filtration system is prone to clogging and is inconvenient to clean. After long-term use, sludge and small particles can easily clog the filter holes, resulting in a decrease in vacuuming efficiency. These issues need to be addressed. Utility Model Content

[0004] The purpose of this application is to provide a road grooving machine that can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a road grooving machine, comprising:

[0006] The frame has casters at the bottom and an engine and handle at the top;

[0007] The cutter head is mounted on the machine frame;

[0008] The dust collection mechanism is mounted on the frame and surrounds the blade disc;

[0009] The dust collection mechanism includes a water spraying structure and a dust blocking structure.

[0010] The aforementioned road grooving machine, through the combined use of the frame, cutter head, and dust collection mechanism, forms a working system integrating grooving operations and dust control. The frame serves as the overall support structure, while the casters mounted at the bottom enable the equipment to move, adapting to different work areas. Simultaneously, the top-mounted engine provides power for the cutter head cutting and the dust collection mechanism, while the handle facilitates operator control of the equipment's direction and speed, enhancing operational convenience.

[0011] The cutter head is mounted on the frame and directly acts on the road surface for grooving operations. The dust collection mechanism surrounds the cutter head to directly control the dust generated during grooving, effectively changing the dust collection lag problem caused by the separation of the dust collection components from the cutting area in existing equipment, thereby reducing dust diffusion. Furthermore, in this application, the dust collection mechanism includes a water spraying structure and a dust blocking structure, forming a composite dust removal mode that blocks, absorbs, and suppresses dust. Compared to existing single dust collection or water spraying methods, this more comprehensively suppresses dust.

[0012] Furthermore, the dust-blocking structure includes:

[0013] The housing is mounted on the frame in a height-adjustable manner;

[0014] Dust-proof edges are located at the top of both sides of the housing.

[0015] The dust guide port is located at the bottom of the side wall of the housing and is used to guide dust.

[0016] The dust-blocking edge is made of flexible material, which can deform and fit with the ground after the shell is lowered, and form a channel to guide dust with the inner wall of the shell and the dust guide port.

[0017] The dust-blocking structure features a height-adjustable housing mounted on a frame. This height adjustment is achieved via a pneumatic cylinder, electric cylinder, or other linear drive system, allowing the housing's height to be dynamically adjusted based on the required groove depth or road surface smoothness. The dust-blocking edges at the bottom of both sides of the housing are made of flexible material, deforming and fitting snugly to the ground shape after the housing is lowered. This eliminates gaps between the housing and the ground, preventing dust from escaping from the sides. Simultaneously, the dust-blocking edges, along with the inner wall of the housing and the dust guide openings, form a closed channel to guide dust, ensuring its directional flow and reducing the incomplete absorption problems caused by disordered dust diffusion in existing equipment. Furthermore, the dust guide openings, installed at the top of the housing sidewalls and connecting to the dust flow channel, efficiently guide accumulated dust into subsequent processing stages, thereby improving dust collection efficiency.

[0018] Furthermore: the dust-proof edge includes:

[0019] Outer layer;

[0020] The inner layer is shorter than the outer layer;

[0021] Both the inner and outer layers are made of rubber.

[0022] In this application, the dust-blocking edge adopts a double-layer structure with an outer and an inner layer, and the inner layer is shorter than the outer layer. Both layers are made of rubber, which utilizes the elasticity of rubber to ensure adhesion to the ground, while the double-layer structure enhances the blocking effect. When the shell height is high, the inner layer cannot contact the ground due to its shorter length, but the outer layer can still play a blocking role, expanding the dust-blocking range and solving the problem that existing single-layer dust-blocking edges either become excessively compressed and deformed or detach from the ground and lose their blocking effect when the height is adjusted. At the same time, the gradient barrier formed by the double-layer structure can gradually weaken the dust diffusion kinetic energy, confining more dust within the channel and reducing the amount of fine dust escaping from the dust-blocking edge.

[0023] Furthermore, the dust-blocking structure also includes a vacuum cleaner, which is connected to the dust guide port via a suction pipe, for absorbing and storing dust discharged from the dust guide port.

[0024] The vacuum cleaner connects to the dust inlet via a suction tube. Using negative pressure, it draws in and stores the dust expelled from the inlet, achieving centralized dust collection. This, combined with the enclosed channel formed by the dust-blocking structure, allows the suction to directly target the dust-accumulating area, improving suction efficiency and solving the problem of suction power loss or inability to absorb scattered dust caused by excessive distance between the suction port and the dust source in existing devices. Furthermore, the centralized storage method facilitates subsequent dust processing.

[0025] Furthermore, a dust cover is provided at the end of the housing away from the dust inlet, and the dust cover is inclined.

[0026] The inclined dust cover installed at the end of the housing away from the dust inlet can block dust on the side away from the dust inlet, change the path of dust diffusion in that direction, and confine it inside the housing. This avoids insufficient dust blocking on both sides, eliminates blind spots in dust collection, and the dust facing the dust cover is less than other parts, so the dust cover is sufficient to block it.

[0027] Furthermore, the water spraying structure includes a water tank, a water pump, a spray pipe, and a spray head connected to the spray pipe, all mounted on a frame, with the spray head facing the cutting direction of the cutter head.

[0028] The water spraying structure stores water in a water tank, is powered by a water pump, and delivers water to the spray heads through spray pipes. The spray heads spray water in the direction of the cutter head, so that the water combines with the dust in the initial stage of dust generation. The water's adsorption effect reduces the dust's floating ability and effectively inhibits the spread of dust.

[0029] The beneficial effects of this application are:

[0030] 1. By forming a closed channel through the dust-blocking structure and working with the vacuum cleaner, it can effectively reduce dust escape, improve dust collection efficiency, and make the absorption more comprehensive, thus effectively controlling dust.

[0031] 2. The double-layer dust-blocking edge structure, which combines inner and outer layers, can expand the dust-blocking range. The water spraying structure reduces dust in the initial stage of dust accumulation, forming a composite dust prevention mode with dust blocking and dust suction, further inhibiting dust diffusion and reducing dust escape.

[0032] 3. The adjustable height of the housing allows it to adapt to different working conditions, and the dust cover can centrally store dust for easy subsequent processing, thus improving the overall adaptability of the equipment. Attached Figure Description

[0039] The road grooving machine provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0040] Example 1:

[0041] like Figure 1 and Figure 2 As shown, this application embodiment provides a road grooving machine, including:

[0042] The frame 100 has casters 110 at the bottom and a motor 120 and a handle 130 at the top;

[0043] The cutter head 200 is mounted on the frame 100;

[0044] A dust collection mechanism is mounted on the frame 100 and surrounds the blade disc 200;

[0045] The dust collection mechanism includes a water spraying structure 300 and a dust blocking structure 400.

[0046] In some embodiments of this application, such as Figure 1 As shown, the road grooving machine described above, through the combined use of the frame 100, cutter head 200, and dust collection mechanism, forms a working system integrating grooving operations and dust control. The frame 100 serves as the overall support structure, while the rollers 110 installed at the bottom enable the equipment to move, thus adapting to the transfer and movement of different work areas. At the same time, the engine 120 on the top provides power for the cutting of the cutter head 200 and the operation of the dust collection mechanism, while the handle 130 facilitates the operator's control of the equipment's direction and speed, improving the convenience of operation.

[0047] The cutter head 200 is mounted on the frame 100 and directly acts on the road surface for grooving operations. The dust collection mechanism surrounds the cutter head 200 to directly control the dust generated during grooving, effectively changing the dust collection lag problem caused by the separation of the dust collection components from the cutting area in existing equipment, thereby reducing dust diffusion. Furthermore, in this application, the dust collection mechanism includes a water spraying structure 300 and a dust blocking structure 400, forming a composite dust removal mode that blocks, absorbs, and suppresses dust. Compared to existing single dust collection or water spraying methods, this more comprehensively suppresses dust.

[0048] Example 2:

[0049] This application provides a road grooving machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0050] like Figures 1 to 3 As shown, the dust-blocking structure 400 includes:

[0051] The housing 410 is mounted on the frame 100 in a height-adjustable manner;

[0052] Dust-proof edges 420 are provided on the top of both sides of the housing 410;

[0053] Dust guide port 430 is located at the bottom of the side wall of housing 410 and is used to guide dust.

[0054] The dust-blocking edge 420 is made of flexible material, which can deform and fit with the ground after the housing 410 is lowered, and form a channel to guide dust with the inner wall of the housing 410 and the dust guide port 430.

[0055] In this embodiment, the housing 410 of the dust-blocking structure 400 is vertically and flexibly mounted on the frame 100. Lifting can be achieved via a cylinder, electric cylinder, or other linear drive, allowing the housing 410 to dynamically adjust its height according to the required groove depth or road surface flatness. The dust-blocking edges 420 at the bottom of both sides of the housing 410 are made of flexible material. After the housing 410 is lowered, it deforms with the ground shape and fits tightly, eliminating the gap between the existing rigid dust-blocking structure 400 and the ground, preventing dust from escaping from the sides. Simultaneously, the dust-blocking edges 420, together with the inner wall of the housing 410 and the dust guide port 430, form a closed channel for guiding dust, allowing dust to flow directionally within the channel and reducing the problem of incomplete absorption caused by disordered dust diffusion in existing equipment. Furthermore, the dust guide port 430 is installed on the top of the side wall of the housing 410, connecting to the dust flow channel, enabling efficient introduction of accumulated dust into subsequent processing stages, thereby improving dust collection efficiency.

[0056] Furthermore, the dust guard edge 420 includes:

[0057] Outer layer 421;

[0058] The inner layer 422 is shorter than the outer layer 421;

[0059] Both the inner layer 422 and the outer layer 421 are made of rubber.

[0060] In this application, the dust-blocking edge 420 adopts a double-layer structure of an outer layer 421 and an inner layer 422, with the inner layer 422 being shorter than the outer layer 421. Both layers are made of rubber, which utilizes the elasticity of rubber to ensure adhesion to the ground while enhancing the blocking effect through the double-layer structure. When the shell 410 is high, the inner layer 422, due to its shorter length, cannot contact the ground. At this time, the outer layer 421 can still play a blocking role, expanding the dust-blocking range and solving the problem that existing single-layer dust-blocking edges 420 either become excessively compressed and deformed or detach from the ground and lose their blocking effect when the height is adjusted. At the same time, the gradient barrier formed by the double-layer structure can gradually weaken the dust diffusion kinetic energy, confining more dust within the channel and reducing the amount of fine dust escaping from the edge of the dust-blocking edge 420.

[0061] Furthermore, the dust-blocking structure 400 also includes a vacuum cleaner 440, which is connected to the dust outlet 430 via a suction pipe 450, for absorbing and storing dust discharged from the dust outlet 430.

[0062] The vacuum cleaner 440 is connected to the dust inlet 430 via the suction pipe 450. Using negative pressure, it draws in and stores the dust discharged from the dust inlet 430, thus achieving centralized dust collection. This, combined with the closed channel formed by the dust-blocking structure 400, allows the suction to directly target the dust-accumulating area, improving suction efficiency and solving the problem of suction power loss or inability to absorb scattered dust caused by excessive distance between the suction port and the dust source in existing equipment. Furthermore, the centralized storage method facilitates subsequent dust processing.

[0063] Example 3:

[0064] This application provides a road grooving machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0065] like Figure 2 As shown, a dust cover 460 is also provided at the end of the housing 410 away from the dust inlet 430, and the dust cover 460 is inclined.

[0066] In this embodiment, the inclined dust cover 460 installed at the end of the housing 410 away from the dust inlet 430 can block the dust on the side away from the dust inlet 430, change the path of the dust spreading in that direction, and confine it inside the housing 410. This avoids insufficient dust blocking by the dust blocking edges 420 on both sides, eliminates the dust suction blind spot, and the dust facing the dust cover 460 is less than that in other parts, so the dust cover 460 is sufficient to block it.

[0067] Example 4:

[0068] This application provides a road grooving machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0069] like Figure 1 As shown, the water spraying structure 300 includes a water tank 310, a water pump 320, a spray pipe 330 and a spray head 340 connected to the spray pipe 330, which are mounted on the frame 100. The spray head 340 faces the cutting direction of the cutter head 200.

[0070] In this embodiment, the water spraying structure 300 stores water in a water tank 310 and is powered by a water pump 320. The water is then transported to the spray head 340 via a spray pipe 330. The spray head 340 sprays water in the cutting direction of the cutter head 200, so that the water combines with the dust in the initial stage of dust generation. The water's adsorption effect reduces the dust's floating ability and effectively inhibits the spread of dust.
