[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, when the air compressor body is working and inhaling air, the gas can be filtered through the filter body on one side. When the air enters the silencer shell and the guide seat, the force of the air suction can be introduced into the arc seat and the silencer pipe through the guide seat on one side. The overflowing air reduces the flow rate through multiple air outlets while reducing the friction with the inner cavity of the silencer shell. Multi-stage silencing and deceleration are performed through multiple sliding seats with different inner diameters. The decelerated air can enter the intake bend on one side through the silencer shell and refract and reduce noise through the arc silencer plate on one side.

[0027] 2. In the present invention, the snap-fit ​​seat is opened and separated from the rear protective shell. When the air compressor body enters the inner cavity of the protective shell, the snap-fit ​​seats on both sides can contact and fit with the air compressor body. At this time, the snap-fit ​​seat can be inserted into the snap-fit ​​seat on one side through the L-shaped assembly blocks at the corresponding positions on both sides. The T-shaped assembly seat connected to the protective shell can be limited and assembled and fixed after the L-shaped assembly block is inserted. The sealing gasket in the inner cavity of the snap-fit ​​seat can be squeezed and limited to fit the air compressor body through the bottom telescopic rod and the first spring to reduce the circulation and exchange of internal and external air, ensure the stability of the working state of the air compressor body, so that the protective shell can be quickly assembled with the air compressor body. While performing noise reduction protection, the efficiency of subsequent disassembly and maintenance is improved, the maintenance difficulty of the staff is reduced, and the use needs are met.

[0028] 3. In the present invention, after the adjusting mechanism at the top of the air compressor body is connected to the air inlet pipe, the bellows can be offset and rotated through its own steel belt. When the fastening bolt is tightened to separate it from the inner adjusting rod, the fixing seat is pulled to offset by sliding the adjusting sleeve outside the adjusting rod. The fixing seat can pull the bottom bellows to deflect, and then the relative deflection angle of the top air intake mechanism can be adjusted to adapt to the adjustment needs of different exhaust and material feeding, avoiding the inlet being blocked by obstacles and affecting the overall air intake volume.

[0029] 4. In the present invention, through the designed silencer shell, the second through grooves on both sides of the inner cavity of the silencer shell can facilitate the guide seat to quickly move into the rear limit groove through the arc-shaped limit blocks on both sides. After the limit block moves into the limit groove, the limit block can be driven to be stuck in the limit groove by rotating the guide seat, and the stepped structure of the silencer shell and the limit groove can movably limit the limit block, which effectively facilitates the staff to disassemble, clean and maintain the silencer shell, the internal guide seat and the silencer pipe to avoid dust accumulation affecting the dust removal effect.

[0030] 5. In the present invention, the air compressor body can be moved into the inner cavity of the protective shell, and the support seat at the bottom of the air compressor body is fitted with the protective shell. When the air compressor body cable can be connected and discharged through the top junction box, when the air compressor body generates noise during operation, the multiple stepped silencing cavities in the inner cavity of the protective shell can reduce the sound wave conduction intensity by refraction of the sound wave noise, and can weaken the sound wave through the silencing cotton in the silencing cavity, thereby protecting the air compressor body while reducing the adverse effects of the noise generated by its operation on the production environment.

A fixing column is attached to the bottom of the filter body 601, and the fixing column is fixedly connected to the top of the protective shell 1. Second through grooves 605 are provided on both sides of one end of the silencer shell 604, and a limiting groove 606 is provided at a position corresponding to the inner cavity of the silencer shell 604 and the end of the second through groove 605, and the end of the limiting groove 606 is attached to the limiting block 608, and the limiting blocks on both sides are provided. A guide seat 607 is fixedly connected between the positioning blocks 608, and guide sleeves are embedded at both ends of one side of the guide seat 607, and a guide rod 609 is slidably connected in the guide sleeve, and a plurality of guide sleeves are slidably connected to the outer wall of the guide rod 609, and a slidable slide seat 619 is embedded between the corresponding guide sleeves, and a muffler pipe 610 is connected to the rear side of the guide seat 607 and the slide seat 619, and a plurality of air outlet holes 611 are opened on the outer wall of the muffler pipe 610, and an arc seat 612 is fixedly connected to the other end of the muffler pipe 610, and the slide seat 619 is slidably connected in the muffler shell 604, and the outer wall of the guide rod 609 is sleeved with a plurality of guide sleeves. There is a second spring 613, and the two ends of the second spring 613 are respectively fixedly connected to the silencer seat 615 and one side of the slide seat 619 at the corresponding positions, the cross-sectional shape of the inner cavity of the arc seat 612 is arc-shaped, and the arc seat 612 is a silencer foam aluminum component, the guide seat 607 and the slide seat 619 are successively smaller, the arc surface of the inner cavity of the air intake elbow 614 is hinged with the silencer seat 615 through a pin shaft 617 and a sleeve 618, and a silencer plate 616 is fixedly connected to one side of the silencer seat 615, and the silencer plate 616 and the inner cavity and one side of the air intake elbow 614 are all arc-shaped surfaces, and the silencer plate 616 is a foam aluminum component.

[0044] The specific implementation method is as follows: when the air compressor body 2 is working and inhaling air, the gas can be filtered through the filter body 601 and the filter plate 602 on one side. The filter body 601 can absorb large particles in the air, and the bottom of the filter body 601 is abutted with a support column to ensure the stability of the air intake. After the particles are filtered, the air can enter the muffler shell 604 on one side. When the air enters the muffler shell 604 and the guide seat 607, the force of the air pumping can be introduced into the arc seat 612 and the muffler pipe 610 through the guide seat 607 on one side. The arc surface of the inner cavity of the arc seat 612 can resist the linear impact force when the air enters, and is dispersed to one side of the muffler pipe 610 through the arc inner cavity and overflows through the air outlet 611. The overflowing air reduces the flow rate through the multiple air outlets 611 while reducing the friction with the inner cavity of the muffler shell 604, and enters the next level of the slide seat 619 with a smaller inner diameter. When the arc surface connected to one side of the slide seat 619 is subjected to arc-shaped stress dispersion by the incoming air, it can slide outside the guide rod 609 through the external guide sleeve. When the slide seat 619 slides, it can squeeze the second spring 61 on one side. 3. The second spring 613 can resist the stress of the slide 619 being blown by the airflow, and after the air intake stops, the second spring 613 can be forced to pull the slide 619 to reset through the guide rod 609, and then the impact force of the high-speed airflow can be absorbed by the elastic force of the second spring 613. At the same time, multiple slides 619 with different inner diameters are used to perform multi-stage silencing and deceleration. The decelerated air can enter the intake elbow 614 on one side through the silencer shell 604, and the silencer seat 615 in the intake elbow 614 can further flow through the arc-shaped silencer plate 616 on one side. The moving air is refracted to reduce noise, and the silencer seat 615 can rotate outside the pin shaft 617 through the top sleeve 618, and then the contact area with the airflow can be increased by the deflection of the arc surface, and the airflow is guided to the bottom bellows 401. The flow rate and impact pressure of the direct air are reduced through the cooperation of the intake elbow 614, and the impact of the high air flow velocity on the inlet guide vane is avoided, and the surge noise of the inlet guide vane is reduced. The noise generated when the air compressor body 2 is pumping and inlet, and the service life of the silencer pipe 610 and the inlet guide vane in the air compressor body 2 is effectively improved.

[0045] The arc surface of the inner cavity of the air intake elbow 614 is hinged with a muffler seat 615 through a pin shaft 617 and a sleeve 618, and a muffler plate 616 is fixedly connected to one side of the muffler seat 615, and the muffler plate 616 and the inner cavity and one side of the air intake elbow 614 are all arc surfaces, and the muffler plate 616 is a foam aluminum component, a groove 504 is opened on one side of the inner cavity of the first through groove 505, and a telescopic rod 507 is fixedly connected to the bottom of the inner cavity of the groove 504, and a sealing gasket 506 is fixedly connected to the top of the telescopic rod 507, and a first spring 508 is sleeved on the outer wall of the telescopic rod 507, and the two ends of the first spring 508 are respectively connected to the sealing gasket 506 and the outer wall of the telescopic rod 507. One side of the wall is fixedly connected, and the sealing gasket 506 is located in the groove 504, and the sealing gasket 506 is fitted with the top air compressor body 2, the top of the protective shell 1 is fixedly connected with a pull rod 9, and the cross-sectional shape of the pull rod 9 is U-shaped, and the roller 3 on one side of the protective shell 1 is larger than the roller 3 on the other side, the inner cavity of the protective shell 1 is provided with a plurality of rectangular silencer cavities 8, and the inner cavity of the silencer 8 is fixedly connected with silencer cotton, and the top side of the protective shell 1 is fixedly connected with a junction box 10, and the top of the junction box 10 is provided with a wire outlet hole for accommodating cables to pass through, the bottom sides of the air compressor body 2 are fixedly connected with support seats 7, and the support seat 7 is fitted with one side of the inner cavity of the protective shell 1.

[0046] like Figure 3-4The specific implementation method is as follows: by opening the card seat 501 and separating it from the rear protective shell 1, the air compressor body 2 can be moved into the inner cavity of the protective shell 1, and the support seat 7 at the bottom of the air compressor body 2 is fitted with the protective shell 1. When the air compressor body 2 generates noise during operation, the multiple step-mounted silencer cavities 8 in the inner cavity of the protective shell 1 can reduce the sound wave conduction intensity by refraction of the sound wave noise, and can weaken the sound wave through the silencer cotton in the silencer cavity 8, thereby protecting the air compressor body 2 while reducing the adverse effects of the noise generated by its operation on the production environment. When the air compressor body 2 enters the inner cavity of the protective shell 1, the card seats 501 on both sides can contact and fit with the air compressor body 2. At this time, the card seat 501 can be clamped into one through the L-shaped assembly blocks 503 at the corresponding positions on both sides. In the side clamping seat 501, the T-shaped assembly seat 502 connected to the protective shell 1 can be limitedly assembled and fixed after the L-shaped assembly block 503 is clamped in, and the sealing gasket 506 in the inner cavity of the clamping seat 501 can be squeezed and limited to fit the air compressor body 2 through the bottom telescopic rod 507 and the first spring 508. The sealing gasket 506 can reduce the assembly gap between the clamping seats 501 on both sides and the air compressor body 2 to prevent the noise in the inner cavity of the air compressor body 2 from overflowing from the protective shell 1, and the rear heat dissipation mechanism of the air compressor body 2 extends out of the rear clamping seat 501, thereby reducing the circulation and exchange of internal and external air, and thereby ensuring the stability of the working state of the air compressor body 2, so that the protective shell 1 and the air compressor body 2 can be quickly assembled, while performing noise reduction protection, improving the efficiency of subsequent disassembly and maintenance, reducing the maintenance difficulty of staff, and meeting the use needs.

[0047] The adjustment mechanism 4 includes a bellows 401, and the bottom of the bellows 401 is connected to the air inlet of the air compressor body 2, and the top of the bellows 401 is connected to a fixed seat 404, and the top of the fixed seat 404 is connected to an air intake pipe 405, and the air intake pipe 405 is connected to the top air intake mechanism 6, a direction adjustment sleeve 403 is embedded on one side of the top of the fixed seat 404, and a direction adjustment rod 402 is slidably connected to the inner cavity of the direction adjustment sleeve 403, and a fastening nut is embedded on one side of the direction adjustment sleeve 403 and the fixed seat 404, and a fastening bolt 406 is connected to the inner thread of the fastening nut, the bellows 401 is a steel belt reinforced bellows, the top of the direction adjustment rod 402 is arranged in a semicircular arc shape, and the direction adjustment rod 402 cooperates with the direction adjustment sleeve 403.

[0048] like Figure 1-2 and Fig. 9The specific implementation method is as follows: after the adjustment mechanism 4 at the top of the air compressor body 2 is connected to the air inlet pipe 405, the bellows 401 can be offset and rotated by its own steel belt. When the fastening bolt 406 is screwed and moved in the fastening nut to separate from the inner adjustment rod 402, the fixing seat 404 can be pulled to slide and rotate outside the adjustment rod 402 through the adjustment sleeve 403. The adjustment sleeve 403 can slide outside the semicircular arc of the adjustment rod 402. When the adjustment sleeve 403 slides, it is limited by the adjustment rod 402 and pulled. The movable fixing seat 404 is offset, and the fixing seat 404 can pull the bottom bellows 401 to deflect, and then the relative deflection angle of the top air intake mechanism 6 can be adjusted to adapt to the adjustment needs of different air extraction and feeding, and avoid the inlet being blocked by obstacles and affecting the overall air intake volume, and the fastening bolt 406 can improve the limiting stability of the fixing seat 404 by squeezing the adjustment rod 402, avoid the movement of the protective shell 1 and cause the top air intake mechanism 6 to deflect, and improve the overall movement stability.

[0049] Working principle: When in use, the air compressor body 2 works to inhale air, and the gas is filtered through the filter body 601 and the filter plate 602 on one side. The filter body 601 absorbs large particles in the air and enters the silencer shell 604 on one side. The air enters the silencer shell 604 and the guide seat 607. The force of the air suction is introduced into the arc seat 612 and the silencer pipe 610 through the guide seat 607 on one side. The arc surface of the inner cavity of the arc seat 612 resists the linear impact force of the air entering, and is dispersed to one side of the silencer pipe 610 through the arc inner cavity and overflows through the air outlet 611. The overflowed air reduces the flow rate through multiple air outlets 611 to reduce the friction with the inner cavity of the silencer shell 604, and enters the next level with a smaller inner diameter. Inside the slide 619, the slide 619 slides outside the guide rod 609 through an external guide sleeve to squeeze the second spring 613 on one side. The second spring 613 is subjected to force to resist the stress of the slide 619 being blown by the airflow, and after the air intake is stopped, the second spring 613 is forced to pull the slide 619 to reset through the guide rod 609, and the decelerated air enters the air intake bend 614 on one side through the silencer shell 604. The silencer seat 615 in the air intake bend 614 further refracts the flowing air through the arc-shaped silencer plate 616 on one side to reduce noise, and the silencer seat 615 rotates outside the pin shaft 617 through the top sleeve 618, and then increases the contact area with the airflow through the deflection of the arc surface, and guides the airflow to the bottom bellows 401.

[0050] By opening the snap-fit ​​seat 501 and separating it from the rear protective shell 1, the air compressor body 2 moves into the inner cavity of the protective shell 1, and the support seat 7 at the bottom of the air compressor body 2 is fitted with the protective shell 1. The cables of the air compressor body 2 are connected and discharged through the top junction box 10. The air compressor body 2 generates noise during operation. The multiple step-mounted silencing chambers 8 in the inner cavity of the protective shell 1 reduce the intensity of sound wave conduction by refracting the sound wave noise. After the air compressor body 2 enters the inner cavity of the protective shell 1, the snap-fit ​​seats 501 on both sides are in contact with the air compressor body 2. The clamping seat 501 is inserted into the clamping seat 501 on one side through the L-shaped assembly blocks 503 at the corresponding positions on both sides. The T-shaped assembly seat 502 connected to the protective shell 1 is limitedly assembled and fixed after the L-shaped assembly block 503 is inserted. The sealing gasket 506 in the inner cavity of the clamping seat 501 is squeezed and limited to fit the air compressor body 2 through the bottom telescopic rod 507 and the first spring 508. The sealing gasket 506 reduces the assembly gap between the clamping seats 501 on both sides and the air compressor body 2.

[0051] After the adjustment mechanism 4 at the top of the air compressor body 2 is connected to the air intake pipe 405, the bellows 401 can be offset and rotated through its own steel belt, and the fastening bolt 406 is turned to separate it from the inner adjustment rod 402. The fixing seat 404 is pulled to slide and rotate outside the adjustment rod 402 through the adjustment sleeve 403. The adjustment sleeve 403 moves to slide on the semicircular arc outside of the adjustment rod 402 to pull the fixing seat 404 for offset. The fixing seat 404 pulls the bottom bellows 401 for deflection to adjust the relative deflection angle of the top air intake mechanism 6.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
