For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Combine the following Figures 1 to 3 The utility model is described in detail.

[0023] A tunnel operation dust removal device includes a main body 1, a suction port 101 is provided on one side of the main body 1, an air outlet 102 is provided on the top of the main body 1, a filter screen 103 is connected to the inside of the main body 1 near the suction port 101, the top part of the filter screen 103 protrudes from the top surface of the main body 1, a connecting block 104 is provided at the bottom of the main body 1 connected to the filter screen 103, a correction slope 1041 is provided on the top of the connecting block 104, a dust collecting component is provided on the top of the main body 1, and one side of the dust collecting component is connected to the filter screen 103.

[0024] First, air containing dust and impurity particles in the tunnel is sucked in through the air inlet 101, and the air is passed through the filter 103 to block the dust and particles in the air. Then, the filtered air is discharged through the air outlet 102, and this process is continued to filter and purify the air in the tunnel.

[0025] Furthermore, the connection blocks 104 are arranged in groups of two, and the distance between each two connection blocks 104 matches the thickness of the filter 103. The alignment slope 1041 is a slope arranged at the top of the opposite side of the two connection blocks 104 and tilted toward the center.

[0026] At the same time, when the filter is inserted and connected, the bottom will contact the alignment slope 1041 in the middle of the connecting block 104, so that when the filter 103 is plugged in and connected, it can be guided by leaning against the alignment slope 1041, so that it can be smoothly inserted into the connecting blocks 104 for a stable connection.

[0027] Further, the dust collecting assembly includes a collecting block 2, a collecting chamber 201, a stop block 202, a stop shaft 203 and a slider 204, the collecting block 2 is arranged at the top of the inside of the body 1, the collecting chamber 201 is arranged inside the collecting block 2, the stop block 202 is arranged at the top of the opening on one side of the collecting chamber 201, the stop shaft 203 is connected to the bottom of the opening on one side of the collecting chamber 201, the slider 204 is arranged at the top of the collecting block 2, and the stop block 202 is arranged at an angle at the top of the opening on one side of the collecting chamber 201. The protrusion, the shaft 203 is a circular shaft set at the bottom of the opening on one side of the collecting chamber 201, and a certain gap is left between the side of the collecting chamber 201 where the shaft 203 is set and the filter 103, the shaft 203 also includes a gear ring 2031, the gear ring 2031 is set on the side walls at both ends of the shaft 203, the gear ring 2031 is meshed with the edge racks on both sides of the filter 103, the main body 1 also includes a slide groove 105, the slide groove 105 is set at the top of the main body 1, and the slide groove 105 cooperates with the slider 204.

[0028] When the dust and particles are filtered through the filter 103, a large amount of dust and particles will be adsorbed and accumulated on the surface of the filter. When the filter 103 needs to be cleaned, the filter 103 is lifted up by applying force to the part of the filter 10 protruding from the top of the main body 1. When the filter 103 is lifted up, the side on which the dust and particles are attached will fit against the stop block 202 for displacement. Through the fit between the stop block 202 and the filter 103, when the filter 103 is lifted up for movement, the dust and particles attached to the surface of one side of the filter 103 will be cleaned up by the stop block 202, and then fall onto the stop shaft 203 and slide into the collection chamber 201 for collection.

[0029] At the same time, when the filter 103 is lifted, the racks on both sides thereof will engage with the gear rings 2031 at both ends of the abutment shaft 203, so that when the filter 103 is lifted, the abutment shaft 203 will be driven to rotate toward one side of the collecting chamber 201, and the dust and particles falling onto the abutment shaft 203 will fall into the collecting chamber 201 through the rotation direction toward the collecting chamber 201, and the collecting chamber 201 will not fit the lower half of the filter 2 and can collect the cleaned dust and particles even when it is not fitting the filter.

[0030] The following is a specific implementation process of the utility model. First, the air containing dust and impurity particles in the tunnel is sucked in through the air inlet 101, and the air is passed through the filter 103 to block the dust and particles in the air. Then, the filtered air is discharged through the air outlet 102. In this way, the air in the tunnel is continuously filtered and purified to a certain extent. When the dust and particles are filtered through the filter 103, a large amount of dust and particles will be adsorbed and accumulated on the surface of the filter. When the filter 103 needs to be cleaned, the part of the filter 10 protruding from the top of the main body 1 is pulled by applying force to the filter 10 so that the filter 103 is lifted up. When the filter 103 is lifted up, the side attached to the dust and particles will fit the stop block 202 for displacement. Due to the fit between the stop block 202 and the filter 103, when the filter 103 is lifted and moved, the dust and particles attached to the surface of one side of the filter 103 will be cleaned by the stop block 202, and then fall onto the stop shaft 203 and slide into the collection chamber 201 for collection. At the same time, when the filter 103 is lifted, the racks on both sides thereof will engage with the gear rings 2031 at both ends of the stop shaft 203, so that when the filter 103 is lifted, the stop shaft 203 will be driven to rotate toward one side of the collection chamber 201, and the dust and particles falling onto the stop shaft 203 will fall into the collection chamber 201 through the rotation direction of the collection chamber 201, and the collection chamber 201 will not be able to collect the cleaned dust and particles even when it is not fitted with the filter because the collection chamber 201 fits the lower half of the filter 2.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
