Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 2 and Figure 4 Slide grooves 102 are arranged on the inner walls on both sides of the N-shaped frame 101, and sliders 206 are arranged on the surfaces at both ends of the box body 201. Each slider 206 is slidably connected in the corresponding slide groove 102. One end of the screw rod 207 is rotatably connected on the top surface of the box body 201. A penetrating threaded hole is opened on the top inner wall of the N-shaped frame body 101, and the screw rod 207 is threadedly connected to the threaded hole.

[0025] The box body 201 is slidably installed between the inner walls of the N-shaped frame 101 via sliders 206 arranged on the surfaces of both ends. When the user rotates the screw 207, the box body 201 as a whole can be driven to slide up and down independently relative to the N-shaped frame 101, so that the height of the dust hood 202 can be adjusted. It can be flexibly adjusted according to the usage scenario and needs, reducing limitations during use.

[0026] Furthermore, a mounting circular groove 208 is provided on the inner wall at the bottom of the box body 201 , a disc 209 is rotatably installed in the mounting circular groove 208 , and the dust hood 202 is fixedly connected to the bottom surface of the disc 209 and one end is connected to the upper surface of the disc 209 .

[0027] The dust hood 202 is connected to the interior of the box 201 through the disc 209. When the internal threaded sleeve 205 is connected to the vacuum pipe of the negative pressure pump, the interior of the box 201 is in a negative pressure state. The dust near the conveyor can be sucked into the box 201 through the dust hood 202. The disc 209 is rotatably installed in the mounting circular groove 208, so the two dust hoods 202 can be independently adjusted in angle relative to the box 201, so that the dust hoods 202 can absorb dust more efficiently.

[0028] Furthermore, there are two dust hoods 202 disposed on the bottom surface of the disc 209, and the two dust hoods 202 are symmetrically distributed.

[0029] The two symmetrically distributed dust hoods 202 can expand the dust suction range, thereby further improving the dust prevention efficiency.

[0030] Furthermore, a connecting pipe 203 is also provided on the other side surface of the box body 201, and the outer wall of the connecting pipe 203 is provided with threads, and is connected to a sealing cover 210 through the threads.

When multiple boxes 201 are needed to be used in combination for vacuuming, the internal threaded sleeve 205 on the box 201 closest to the negative pressure pump can be connected to the vacuum pipe of the negative pressure pump, and the remaining sealing covers 210 except the box 201 farthest from the negative pressure pump can be removed, and the internal threaded sleeves 205 on the remaining boxes 201 can be connected to the adjacent connecting pipes 203 to complete the series connection of several boxes 201. Several boxes 201 can be vacuumed synchronously through one negative pressure pump to increase the dust prevention range and dust collection efficiency.

[0032] Furthermore, filters 211 are provided at the connection points between the two connecting pipes 203 and the box body 201 .

[0033] The filter 211 can be provided to prevent dust from eventually accumulating in the box 201 closest to the negative pressure pump and causing blockage when several boxes 201 are connected in series. Each box 201 can store dust independently, which can reduce dust accumulation and blockage.

[0034] Furthermore, a dust removal port is provided on one side surface of the box body 201, and a box door 212 is rotatably installed on one side edge of the dust removal port.

[0035] By providing a dust removal port on the surface of the box body 201, the dust inside the box body 201 can be removed after the dust prevention work is completed so as to facilitate the next use. A locking mechanism is provided on the box door 212 to improve the stability during use.

[0036] See also Figure 3The clamping and mounting mechanism includes a bidirectional screw 104, both ends of which are rotatably mounted on one side between the two ends of the N-shaped frame 101, and a sliding rod 105 is fixedly mounted on one side of the bidirectional screw 104 located between the two ends of the N-shaped frame 101, and two oppositely disposed splints 106 are slidably mounted on the sliding rod 105, and two oppositely disposed splints 106 are threadedly connected at both ends of the bidirectional screw 104, and the two splints 106 located at the same end are fixedly connected by a connecting plate 107.

[0037] When in use, the N-type frame 101 is placed as a whole at a suitable position above the conveyor, and the bidirectional screw 104 is rotated to drive the two oppositely arranged clamps 106 on the bidirectional screw 104 to move in opposite directions, and the other two clamps 106 are synchronously driven to move synchronously through the connecting plate 107, so that the two groups of clamps 106 can be clamped on the surfaces of both sides of the conveyor frame, and the dust collection hood 202 is located above the conveyor to absorb the raised dust and prevent it from spreading, and the convenience of the installation and disassembly process is improved by the clamping installation method.

[0038] Working principle: When in use, place the N-type frame 101 as a whole at a suitable position above the conveyor, and rotate the bidirectional screw 104 to drive the two oppositely arranged clamping plates 106 on the bidirectional screw 104 to move in opposite directions, and synchronously drive the other two clamping plates 106 to move synchronously through the connecting plate 107, so that the two sets of clamping plates 106 can be clamped on the surfaces of both sides of the conveyor frame, so that the dust cover 202 is located above the conveyor. When a box 201 is used independently, a connecting pipe 203 is connected to the negative pressure pump through the internal threaded sleeve 205, and the sealing cover 210 is installed at the end of the other connecting pipe 203 for sealing. When multiple boxes 201 need to be used in combination for dust collection, Connect the internal threaded sleeve 205 on the box 201 closest to the negative pressure pump to the vacuum pipe of the negative pressure pump, remove the remaining sealing covers 210 except the box 201 farthest from the negative pressure pump, and connect the internal threaded sleeves 205 on the remaining boxes 201 to the adjacent connecting pipes 203 to complete the series connection of several boxes 201. Through a negative pressure pump, several boxes 201 can be dusted synchronously to increase the dust prevention range and dust collection efficiency. The dust hood 202 set at the bottom of each box 201 can also adjust the angle by rotating the disc 209 to further reduce the dust collection dead angle and improve the dust prevention efficiency. After the dust prevention work is completed, the box door 212 can be opened to remove the dust inside the box 201 for next use.

[0039] It should be noted that the specific model and specifications of the negative pressure pump need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The power supply and principle of the negative pressure pump are clear to those skilled in the art and will not be described in detail here.

[0041] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
