The suction arm can hover at any position in three-dimensional space by itself and is installed at the front end of the engineering system.

[0003] In the Chinese patent document with the publication number CN211802950U, a negative pressure suction arm is disclosed, which includes a purifier and a suction arm. A suction pipe is fixedly arranged at the lower end of the suction arm. A suction hood is fixedly arranged at the lower end of the suction pipe. Symmetric connecting pipes are fixedly arranged at both ends of the suction pipe. Threads are arranged inside both connecting pipes. A first mounting plate and a second mounting plate are symmetrically arranged on the side walls of the two connecting pipes respectively. A sealing plug is threadedly connected inside the first mounting plate. A sleeve is fixedly arranged at the right end of the second mounting plate. Symmetric cavities are arranged on the side wall of the sleeve. Fixing mechanisms are arranged inside both cavities. An extension pipe is fixedly arranged at the right end of the sleeve. Through the common cooperation of a lead screw, a rotating block, a slider, a U-shaped block, and a limiting rod, the sleeve and the second mounting plate can be quickly installed, and multiple suction hoods can be quickly installed.

[0004] The deficiencies of the above disclosed solution are as follows: Although the suction hood can be disassembled and assembled, the method of disassembling and assembling by screwing the lead screw is time-consuming and laborious, resulting in a relatively slow speed of replacing the suction hood and reducing the work efficiency. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an aluminum alloy skeleton suction arm. By using a moving block to limit a limiting column, the disassembly and assembly of the dust suction hood are simple and convenient, and the problems in the background technique can be effectively solved.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an aluminum alloy skeleton suction arm, including a suction pipe. A skeleton is arranged inside the suction pipe. One end of the skeleton is fixedly provided with a mounting block. A limiting column is fixedly arranged at the bottom of the mounting block. One end of the suction pipe is detachably provided with a dust suction hood. An air vent block is fixedly arranged inside the dust suction hood. A clamping groove is arranged on the air vent block. The clamping groove is adapted to the limiting column. A moving block is slidably arranged on the air vent block. The moving block limits the limiting column. A mounting plate is fixedly arranged on the air vent block. A spring is fixedly arranged between the mounting plate and the moving block. A pull rod is fixedly arranged on one side of the moving block. The pull rod sequentially slides through the mounting plate and the dust suction hood and extends to the outside of the dust suction hood.

[0007] Further, the moving block is fan-shaped and is slidably engaged with the limiting post.

[0008] Further, a chute is formed on the ventilation block, a slider is fixedly arranged at the bottom of the moving block, and the slider is slidably connected with the chute.

[0009] Further, a mounting seat is fixedly sleeved at one end of the suction pipe away from the dust suction cover, the mounting seat is fixedly connected with a connecting plate through bolts, and a fixing plate is fixedly arranged on one side of the connecting plate.

[0010] Further, the skeleton is made of aluminum alloy material.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Since the card slot is adapted to the limiting post and the moving block is slidably arranged on the ventilation block, the moving block limits the limiting post. Therefore, when the dust suction cover needs to be replaced, the pull rod is pulled outwards to drive the moving block to move, and the restriction of the moving block on the limiting post is released, so that the dust suction cover can be disassembled. When installing the dust suction cover, the dust suction cover is sleeved on the suction pipe and moves along the suction pipe. When the limiting post contacts the arc surface of the moving block and is slidably engaged with the moving block, the moving block is pushed to move. The moving block moves to compress the spring. When the limiting post enters the card slot on the ventilation block, the moving block moves under the action of the spring reset, and the moving post restricts the limiting post in the card slot on the ventilation block, thus completing the installation of the dust suction cover and the suction pipe. The disassembly and assembly of the dust suction cover are carried out through the cooperation of the moving block and the limiting post, the operation is simple, time-saving and labor-saving, and the efficiency of replacing the dust suction cover is improved.

The skeleton 6 is made of aluminum alloy material, is not easy to rust, and has a long service life. One end of the skeleton 6 is fixedly provided with a mounting block 14, and a limiting column 8 is fixedly arranged at the bottom of the mounting block 14. One end of the suction pipe 5 is detachably provided with a dust suction hood 7, and an air vent block 15 is fixedly arranged inside the dust suction hood 7, and a through hole is opened on the air vent block 15, and the suction pipe 5 is communicated with the dust suction hood 7 through the through hole.

[0019] A clamping groove is opened on the air vent block 15, and the clamping groove is adapted to the limiting column 8. The air vent block 15 is symmetrically provided with sliding grooves 16, a sliding block 13 is slidably arranged in the sliding grooves 16, a moving block 12 is fixedly arranged on the sliding block 13, and the moving block 12 limits the limiting column 8. Two springs 11 are fixedly arranged between the mounting plates 10 symmetrically fixed on the air vent block 15 and the corresponding moving blocks 12. A pull rod 9 is fixedly arranged on one side of the moving block 12, and the pull rod 9 sequentially slides through the mounting plate 10 and the dust suction hood 7 and extends to the outside of the dust suction hood 7. Pulling the pull rod 9 outwards can release the restriction of the moving block 12 on the limiting column 8, so that the dust suction hood 7 can be disassembled.

[0020] The moving block 12 is fan-shaped, and the arc-shaped side of the moving block 12 is slidably matched with the limiting column 8. When installing the dust suction hood 7, the limiting column 8 can enter the clamping groove on the air vent block 15 without pulling the pull rod 9 outwards.

[0021] A mounting seat 3 is fixedly sleeved at one end of the suction pipe 5 away from the dust suction hood 7, the mounting seat 3 is fixedly connected with a connecting plate 2 through a bolt 4, and a through hole adapted to the suction pipe 5 is opened on the connecting plate 2, which is convenient for communicating with an external suction device.
