Description

Technical Field

[0001] The utility model relates to the technical field of marking removal equipment, in particular to a dust removal device for a road marking removal machine. Background Technique

[0002] Due to reasons such as changes in traffic management plans, it is often necessary to remove the original road markings. Common removal methods include the grinding method, that is, a power device drives a grinding cutter head to rotate at a high speed, and the grinding cutter head fully contacts and grinds the road surface markings to achieve the purpose of removing the markings.

[0003] The existing patent (publication number: CN219080042U) discloses a marking removal device for traffic engineering. When the device is in use, a filter screen is used to filter impurities. However, the filter screen will become blocked after long-term use, and it is inconvenient to clean or replace the device. Content of the Utility Model

[0004] The utility model aims to provide a dust removal device for a road marking removal machine, which is convenient for quickly cleaning or replacing the filter screen.

[0005] For this reason, the technical solution adopted by the utility model is as follows:

[0006] A dust removal device for a road marking removal machine, comprising:

[0007] A vehicle body, on which a driving motor is installed, and a dust-proof cover is installed at the bottom of the vehicle body;

[0008] A dust removal box, which is installed on the vehicle body. An air suction pump is installed at the top of the dust removal box, and a guide air pipe is fixedly connected to the bottom of the dust removal box, and the guide air pipe is mutually communicated with the dust-proof cover;

[0009] A mounting frame, which is fixedly connected to the inner wall of the dust removal box. A filter screen is slidably connected inside the mounting frame. A support plate is fixedly connected to the side wall of the filter screen. A pull rod is slidably connected to the support plate, and an elastic member is sleeved on the pull rod.

[0010] Based on the above technical solution, its working principle and the technical effects produced are:

[0011] When it is necessary to clear the marking line, start the driving motor to drive the grinding cutter head (not shown in the figure) to rotate, and then the marking line can be polished and cleaned. Then start the suction pump to suck air, and use the air duct to absorb the dust generated by grinding inside the dust-proof cover, so that the dust enters the dust removal box. After being filtered by the filter screen, the dust will accumulate at the bottom of the dust removal box, which is convenient for centralized cleaning after grinding, avoiding the scattering of dust and polluting the environment. After long-term use, by opening the movable door and then pulling the pull rod to squeeze the elastic member, the pull rod can also be disengaged from the limit hole, which is convenient for unlocking the filter screen and quickly disassembling it, facilitating its cleaning or replacement, and avoiding dust clogging the filter screen and affecting the filtering effect.

[0012] In a preferred embodiment of the present utility model, it can be further configured that: a controller is installed on the vehicle body, and the controller is electrically connected to both the driving motor and the suction pump.

[0013] In a preferred embodiment of the present utility model, it can be further configured that: a grinding cutter head is installed at the bottom end of the driving motor.

[0014] In a preferred embodiment of the present utility model, it can be further configured that: a movable door is opened on the side wall of the dust removal box, and the movable door is rotatably connected to the dust removal box through a hinge.

[0015] In a preferred embodiment of the present utility model, it can be further configured that: a chute is opened on the mounting frame, and a slider adapted to the chute is installed on the side wall of the filter screen.

[0016] In a preferred embodiment of the present utility model, it can be further configured that: a sealing gasket is fixedly connected to the inner wall of the chute.

[0017] In a preferred embodiment of the present utility model, it can be further configured that: a limit hole adapted to the pull rod is opened on the side wall of the mounting frame.

[0018] In a preferred embodiment of the present utility model, it can be further configured that: one end of the elastic member is fixed on the pull rod, and the other end is fixed on the support plate.

[0019] The explanations of the nouns, connecting words or adjectives involved in the above technical solutions are as follows:

[0020] Fixed connection means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0021] (1) Detachable connection uses screws, splines, wedge pins, etc. to fix the parts together. This connection method can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be fastened properly.

[0022] (2) Non-detachable connections mainly refer to welding, riveting, and mortise fitting, etc. Since forging, sawing, or oxy-fuel cutting is required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as calibration, polishing, etc.);

[0023] A movable connection refers to a connection that has relative movement after fixing parts or components.

[0024] The above technical solutions of the present utility model have the following beneficial technical effects:

[0025] 1. In the present utility model, through the mutual cooperation of the suction pump, dust removal box, and filter screen structure provided, the dust generated during grinding inside the dust-proof cover can be absorbed, enabling the dust to enter the dust removal box. Then, after being filtered by the filter screen, the dust will accumulate at the bottom of the dust removal box, facilitating centralized cleaning after grinding and avoiding the scattering of dust and environmental pollution.

[0026] 2. In the present utility model, through the mutual cooperation of the pull rod, elastic member, and limit hole structure provided, the filter screen can be quickly disassembled, facilitating its cleaning or replacement, and avoiding dust clogging the filter screen and affecting the filtering effect.
