Construction machinery is a general term for mechanical equipment used in engineering construction and urban and rural construction. Screw air compressors are needed in the production of construction machinery.

[0003] Existing screw air compressors used in the production of construction engineering machinery have certain disadvantages during use. There is no filter installed at the air inlet of the screw air compressor. When the screw air compressor is working, the air entering the screw air compressor will contain lint and dust, which will affect the air compression. Moreover, after long-term use of the filter, a large amount of lint and dust will adhere to the filter, thereby clogging the filter, affecting the air intake rate of the screw air compressor and reducing the use effect of the device.

[0023] Example 1

[0024] See also Figures 1 to 3 , which is the first embodiment of the utility model, and provides a technical solution: a screw air compressor for construction engineering machinery production, comprising an air compressor body 1, an air inlet is provided on one side of the air compressor body 1, and the air inlet can be used to draw air outside the air compressor body 1 into the air compressor body 1, and a frame 2 is fixedly connected to the outer ring of the air inlet, and a filter 3 is provided on the side of the frame 2 away from the air compressor body 1, and the filter 3 can filter the air entering the air compressor body 1 to prevent dust and impurities in the air from entering the air compressor body 1 and affecting the air compression inside the air compressor body 1, and bolts are connected between the frame 2 and the filter 3, and the filter 3 can be removed by removing the bolts, and the filter 3 can be replaced, thereby improving the use effect of the device, and a mounting frame 4 is fixedly connected to the side of the air compressor body 1 close to the filter 3, and a cleaning mechanism is provided in the mounting frame 4, which can be used to clean the filter 3;

[0025] The cleaning mechanism includes a screw rod 401 rotatably connected to the mounting frame 4, a driving motor 402 is installed on the top of the mounting frame 4, and the output end of the driving motor 402 passes through the mounting frame 4 and is fixedly connected to one side of the screw rod 401. The driving motor 402 is started to rotate forward and reverse, driving the screw rod 401 to rotate, a slider 403 is screwed on the screw rod 401, the screw rod 401 rotates to drive the slider 403 to move linearly on the screw rod 401, and the slider 403 is rotatably connected to a rotating rod 404 on one side of the filter 3, and the movement of the slider 403 drives the rotating rod 404 to move, a cleaning brush 405 is clamped in the rotating rod 404, and the movement of the rotating rod 404 drives the cleaning brush 405 to clean the surface of the filter 3, and a self-rotation mechanism is provided in the mounting frame 4, which can drive the cleaning brush 405 to rotate.

[0026] A collecting box 8 is installed on one side of the air compressor body 1 close to the filter 3, and the collecting box 8 is located below the filter 3. A pull-out box 9 is slidably connected inside the collecting box 8. A cleaning brush 405 cleans the dust and lint on the surface of the filter 3, and sweeps the dust and lint into the pull-out box 9 in the collecting box 8. The pull-out box 9 is subsequently cleaned by pulling it out.

[0027] Two guide rods 10 are fixedly connected inside the mounting frame 4, and the slider 403 is slidably connected to the guide rods 10. The guide rods 10 are provided to provide a positioning function for the slider 403 when it moves.

[0028] When in use, by starting the driving motor 402 to rotate forward and reverse, the screw rod 401 is driven to rotate, thereby driving the slider 403 to move linearly on the screw rod 401, and then driving the rotating rod 404 to move. The movement of the rotating rod 404 drives the cleaning brush 405 to clean the surface of the filter 3, and sweeps the dust and lint on the filter 3 into the pull-out box 9 in the collection box 8. The pull-out box 9 is subsequently pulled out and cleaned, thereby improving the use effect of the device.

[0029] Example 2

[0030] See also Figure 3 to Figure 4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the self-rotation mechanism includes a spur plate 5 fixedly connected to the mounting frame 4, and a gear 6 is fixedly connected to the outside of the rotating rod 404, and the gear 6 is meshed with the spur plate 5. When the slider 403 drives the rotating rod 404 to move, the gear 6 meshes with the spur plate 5, so that the gear 6 can rotate. The rotation of the gear 6 drives the rotating rod 404 to rotate, thereby driving the cleaning brush 405 to rotate, effectively preventing the cleaning brush 405 from always cleaning the filter screen 3 on one side, thereby improving the cleaning effect of the device. A clamping mechanism is provided in the rotating rod 404, which can be used to clamp the rotating rod 404 and the cleaning brush 405.

[0031] The clamping mechanism includes a fixed rod 7 fixedly connected to the rotating rod 404, and two limit plates 701 are slidably connected to the fixed rod 7. The side of the limit plate 701 away from the gear 6 is fixedly connected with a clamping block 702. When the cleaning brush 405 needs to be disassembled, the two limit plates 701 are moved closer to each other, thereby driving the clamping block 702 to move. A clamping slot is provided in the cleaning brush 405, and the size of the clamping slot is adapted to the size of the clamping block 702. When the clamping block 702 is removed from the clamping slot provided on the cleaning brush 405, the cleaning brush 405 is manually pulled to the side away from the gear 6 to achieve disassembly of the cleaning brush 405.

[0032] A spring 703 is provided between the two limit plates 701, and the spring 703 is sleeved on the outside of the fixing rod 7. The spring 703 is provided so that after the cleaning brush 405 is installed, the block 702 is firmly stuck in the slot under the action of the spring 703, thereby improving the stability of the installation of the cleaning brush 405.

[0033] Two connecting rods 704 are slidably connected to the rotating rod 404, and one side of the connecting rod 704 passes through the rotating rod 404 and is fixedly connected to one side of the limiting plate 701. Manually pressing the two connecting rods 704 can drive the two limiting plates 701 to move closer.

[0034] When in use, when the slider 403 drives the rotating rod 404 to move up and down, the gear 6 meshes with the spur plate 5, so that the gear 6 rotates, and the rotation of the gear 6 drives the rotating rod 404 to rotate, thereby driving the cleaning brush 405 to rotate, so as to avoid the cleaning brush 405 always cleaning the filter screen 3 on one side, thereby improving the cleaning effect of the device;

[0035] And by manually pressing the two connecting rods 704, the two limit plates 701 are driven to move closer to each other. At this time, the spring 703 is forced to contract, and the limit plate 701 moves to drive the block 702 to move out of the slot provided on the cleaning brush 405. Then, the cleaning brush 405 is manually pulled to the side away from the gear 6 to realize disassembly of the cleaning brush 405 for easy cleaning or replacement of the cleaning brush 405.

[0036] The remaining structures are the same as those of Example 1.
