[0014] The present invention provides a hydraulic station with a dustproof structure. It has the following beneficial effects:

[0015] 1. The hydraulic station with a dust-proof structure can absorb the dust floating on the top of the hydraulic station body through the cooperation of the fan, the hose and the dust hood, so as to prevent the dust from falling on the surface of the hydraulic station body and affecting the normal operation of the hydraulic station body. The dust can be filtered and stored by the collection box and the filter screen, and the dust hood can be driven to swing back and forth above the hydraulic station body by the reciprocating rotation of the swing rod on the outer wall of the column. The reciprocating swing of the dust hood can expand its dust suction range, so that the dust hood can fully absorb the dust floating on the top of the hydraulic station body, thereby improving the dust removal effect and preventing the hydraulic station body from being attached to a large amount of dust during operation; and the reciprocating sliding of the push rod and the push plate can compress the dust inside the collection box, so as to compress the volume of the dust so that the collection box can store more dust.

[0016] 2. The hydraulic station with a dust-proof structure drives the swing arm to reciprocate on the outer wall of the column through the L rod, and at the same time, cooperates with the L plate and the connecting rod to drive the slider to slide back and forth on the inner wall of the dust hood. The reciprocating sliding of the slider cooperates with the reset spring, the limit block and the push rod to clear the connection between the hose and the dust hood to prevent dust from being blocked inside the hose and affecting the dust collection effect of the dust hood; at the same time, cooperate with the rack, gear, boss, rotating rod and rubber rod to drive the rubber ball to repeatedly knock on the outer wall of the dust hood. The rubber ball knocking on the outer wall of the dust hood can shake off the dust attached to the inner wall, so that the dust can fully enter the inside of the hose, preventing the dust from accumulating on the inner wall of the dust hood and affecting the dust collection effect of the dust hood.

[0017] 3. In the hydraulic station with a dust-proof structure, when impurities clog the connection between the hose and the dust hood, causing the unblocking of the push rod to be hindered, the slider will drive the pressure sensor to squeeze the pressure plate. After being squeezed by the pressure plate, the pressure sensor will send an electrical signal to the control panel. The control panel will immediately shut down the fan and the motor after receiving the electrical signal from the pressure sensor to prevent the hose from being blocked and causing the fan to be damaged, thereby protecting the fan; and at this time, the pressure plate will push the connecting rod, so that the connecting rod drives the pressure rod to squeeze the limit plate, and then the limit plate can drive the limit rod to move out of the limit hole, so that the limit rod can release the limit of the ring, and then the hose and the dust hood can be separated, so that the staff can deal with the impurities blocking the connection between the hose and the dust hood.

The collecting box 311 is fixedly installed on the outer wall of the hydraulic station body 1. The inner wall of the collecting box 311 is detachably installed with a filter screen 312. The filter screen 312 and the collecting box 311 are bolted. The filter screen 312 and the collecting box 311 can be separated by removing the bolts, so as to deal with the dust inside the collecting box 311. The outer wall of the hydraulic station body 1 is fixedly installed with a fan 313. The fan 313 is electrically connected to the control panel 2. The output end of the fan 313 is connected to the inside of the collecting box 311. The output end of the fan 313 is fixedly installed with a hose 314. The end of the hose 314 away from the fan 313 is fixedly installed A collar 3121 is provided, and the collar 3121 is clamped on the inner wall of the dust hood 33. During the operation of the fan 313, the hose 314 and the dust hood 33 can absorb the dust floating on the top of the hydraulic station body 1. At the same time, the dust can be filtered and collected by using the collection box 311 and the filter 312. The inner wall of the collection box 311 is slidably connected with a push rod 315, and the push rod 315 penetrates the collection box 311. The inner wall of the push rod 315 is slidably connected with a bent rod 317. The side wall of the bent rod 317 is fixedly installed with a telescopic spring 318. The end of the telescopic spring 318 away from the bent rod 317 is fixedly installed on the inner wall of the push rod 315. When the bent rod 317 moves back and forth, the telescopic spring 318 can drive the push rod 315 to slide back and forth on the inner wall of the collection box 311.The curved rod 317 is provided with a slide groove 319, and the side wall of the slide rod 35 is fixedly installed with a slide shaft 3120, and the outer wall of the slide shaft 3120 is attached to the inner wall of the slide groove 319.

[0029] A dust hood 33 is fixedly installed at one end of the swing arm 32 away from the column 31. The bottom of the dust hood 33 is open. The swing arm 32 can drive the dust hood 33 to swing back and forth above the hydraulic station body 1 while reciprocating on the outer wall of the column 31. The reciprocating swing of the dust hood 33 can expand its dust suction range, so that the dust hood 33 can fully absorb the dust floating on the top of the hydraulic station body 1, thereby improving the dust removal effect and preventing the hydraulic station body 1 from being attached to a large amount of dust during operation.

[0030] A push plate 316 is fixedly mounted on the side wall of the push rod 315. The push rod 315 slides back and forth on the inner wall of the collection box 311 in cooperation with the push plate 316 to compress the dust inside the collection box 311, thereby compressing the volume of the dust so that the collection box 311 can store more dust.

[0031] When the embodiment is working, the fan 313 is started during the operation of the hydraulic station body 1, and the fan 313 extracts the air in the hose 314 during the operation, so that the hose 314 extracts the air in the dust hood 33. At this time, the dust hood 33 absorbs the dust floating on the top of the hydraulic station body 1 to prevent the dust from falling on the surface of the hydraulic station body 1, and the air extracted by the fan 313 from the hose 314 is discharged into the collection box 311, so that the air in the collection box 311 is filtered by the filter 312 and then discharged from the collection box.

When the rotating shaft 39 rotates, it will drive the eccentric rod 310 to fit the inner wall of the limiting groove 37 and move back and forth. At the same time, the eccentric rod 310 will push and pull the sliding rod 35 back and forth, so that the sliding rod 35 slides back and forth up and down on the inner wall of the hydraulic station body 1. When the sliding rod 35 slides back and forth up and down, it will drive the L rod 36 to fit the inner wall of the through groove 34 and move back and forth up and down. At the same time, the L rod 36 will move up and down. The swing rod 32 is pushed and pulled repeatedly, so that the swing rod 32 reciprocates on the side wall of the column 31. The reciprocating rotation of the swing rod 32 drives the dust collecting cover 33 to swing back and forth above the hydraulic station body 1. The reciprocating swing of the dust collecting cover 33 can expand its dust collection range to prevent the hydraulic station body 1 from being attached with a large amount of dust during operation. The sliding rod 35 reciprocates up and down on the inner wall of the hydraulic station body 1, and drives the sliding shaft 3120 to move up and down synchronously. At this time, the sliding shaft 3120 will fit the inner wall of the slide groove 319 and reciprocate. The bent rod 317 is moved and pushed and pulled back and forth, so that the bent rod 317 can push and pull the telescopic spring 318 back and forth. At this time, the telescopic spring 318 will push and pull the push rod 315 back and forth, so that the push rod 315 can slide back and forth on the inner wall of the collection box 311. When the push rod 315 slides back and forth, it will drive the push plate 316 to slide back and forth on the inner wall of the collection box 311. When the push plate 316 slides back and forth, it will squeeze the dust inside the collection box 311 back and forth, thereby compressing the volume of the dust so that the collection box 311 can store more dust.

[0032] See also Figure 1-Figure 7On the basis of the above embodiment, another embodiment of the present invention further includes a dredging mechanism 4 and a protective mechanism 5. The dredging mechanism 4 includes a slider 41, a push rod 42, a limit block 43, a return spring 44, an L plate 45, a rack 46, a connecting rod 47, a boss 48, a rotating rod 49, a rubber rod 410, a rubber ball 411 and a gear 412.

The limit block 43 and the slider 41 can drive the push rod 42 to slide and reset through the elastic cooperation of the return spring 44. The L plate 45 is slidably connected to the inner wall of the dust hood 33, and the L plate 45 passes through the dust hood 33. The end of the L rod 36 away from the slide rod 35 is rotatably connected to the side wall of the L plate 45. When the gear 412 is engaged with the rack 46, the L plate 45 can slide back and forth on the inner wall of the dust cover 33.

[0033] Among them, the push rod 42 is slidably connected to the inner wall of the slider 41, and the push rod 42 penetrates the slider 41. The reciprocating sliding of the slider 41 and the push rod 42 can clear the connection between the hose 314 and the dust hood 33 to prevent dust from being blocked inside the hose 314 and affecting the dust collection effect of the dust hood 33.

[0034] A rubber ball 411 is fixedly installed on the end of the rubber rod 410 away from the rotating rod 49, and the outer wall of the rubber ball 411 is in contact with the outer wall of the dust hood 33. The rotation of the rotating rod 49 and the rubber rod 410 can drive the rubber ball 411 to repeatedly knock on the outer wall of the dust hood 33. The knocking of the rubber ball 411 on the outer wall of the dust hood 33 can shake off the dust attached to the inner wall, so that the dust can fully enter the inside of the hose 314, preventing the dust from adhering to the inner wall of the dust hood 33.

[0035] In addition, the protection mechanism 5 includes a pressure plate 51, a pressure sensor 52, a pressure rod 53, a connecting rod 54, a limiting hole 55, a limiting plate 56, a limiting rod 57 and a limiting spring 58. The pressure plate 51 is fixedly installed on the outer wall of the top rod 42, and the inner wall of the slider 41 is slidably connected with the pressure rod 53. One end of the connecting rod 54 is hinged to the outer wall of the pressure rod 53, and the other end of the connecting rod 54 is hinged to the outer wall of the pressure plate 51. When the slider 41 gradually approaches the pressure plate 51, the pressure plate 51 will push the connecting rod 54, and then the connecting rod 54 will push the pressure rod 53, so that the pressure rod 5 When the inner wall of the slider 41 slides downward, the limiting hole 55 is formed on the collar 3121. When the limiting rod 57 is inserted into the limiting hole 55, the collar 3121 is limited to the inner wall of the dust cover 33. The limiting plate 56 is slidably connected to the inner wall of the dust cover 33. The outer wall of the pressure rod 53 is attached to the outer wall of the limiting plate 56. One end of the limiting spring 58 is fixedly mounted on the outer wall of the limiting plate 56. The other end of the limiting spring 58 is fixedly mounted on the outer wall of the dust cover 33. The elasticity of the limiting spring 58 can drive the limiting plate 56 to slide and reset.

[0036] The pressure sensor 52 is fixedly mounted on the outer wall of the slider 41. The pressure sensor 52 is electrically connected to the control panel 2. When the pressure sensor 52 is squeezed by the pressure plate 51, it will send an electrical signal to the control panel 2. Upon receiving the electrical signal from the pressure sensor 52, the control panel 2 will immediately shut down the fan 313 and the motor 38 to prevent the hose 314 from being blocked and causing the fan 313 to be damaged, thereby protecting the fan 313.

[0037] A limiting rod 57 is fixedly installed on the top of the limiting plate 56, and the outer wall of the limiting rod 57 is fitted against the inner wall of the limiting hole 55. When the limiting plate 56 drives the limiting rod 57 to move out of the limiting hole 55, the limiting rod 57 will release the limit on the ring 3121. At this time, the hose 314 can be separated from the dust hood 33, so that the staff can deal with the impurities blocking the connection between the hose 314 and the dust hood 33.

[0038] When the present embodiment is working, the L-rod 36 fits against the inner wall of the through groove 34 and moves back and forth up and down, which in turn drives the L-plate 45 to slide back and forth up and down inside the dust hood 33. When the L-plate 45 slides back and forth up and down, it pushes and pulls the connecting rod 47 back and forth, so that the connecting rod 47 pushes and pulls the slider 41 back and forth, thereby driving the slider 41 to slide back and forth on the inner wall of the dust hood 33. When the slider 41 slides back and forth, it drives the return spring 44 to move back and forth synchronously. When the return spring 44 moves back and forth, it drives the limit block 43 to move back and forth synchronously. When the limit block 43 moves back and forth, it drives the push rod 42 to move back and forth synchronously. During the reciprocating movement of the push rod 42, the dust accumulated at the connection between the hose 314 and the dust hood 33 is repeatedly squeezed to prevent the dust from accumulating inside the hose 314. The dust collecting effect of the dust collecting hood 33 is affected by the blockage of the L plate 45. At the same time, the L plate 45 will slide back and forth on the inner wall of the dust collecting hood 33, and will drive the rack 46 to move back and forth synchronously. The rack 46 will slide back and forth, and will drive the gear 412 meshing with it to rotate back and forth. The gear 412 will reciprocate while driving the rotating rod 49 to rotate back and forth on the inner wall of the boss 48. The reciprocating rotation of the rotating rod 49 will drive the rubber rod 410 to rotate synchronously. During the rotation of the rubber rod 410, the rubber ball 411 will be driven to repeatedly knock on the outer wall of the dust collecting hood 33. The rubber ball 411 knocking on the outer wall of the dust collecting hood 33 can shake off the dust attached to the inner wall, so that the dust can fully enter the inside of the hose 314, thereby preventing the dust from adhering to the inner wall of the dust collecting hood 33.

[0039] When the dust hood 33 sucks in impurities and causes the connection between the hose 314 and the dust hood 33 to be blocked, the push rod 42 will be blocked by the impurities during the process of the slider 41 driving the push rod 42 to squeeze the impurities, which will cause the push rod 42 to remain stationary, while the slider 41 continues to slide on the inner wall of the dust hood 33 and gradually approaches the pressure plate 51. At the same time, the slider 41 will drive the pressure sensor 52 to gradually approach the pressure plate 51. When the slider 41 drives the pressure sensor 52 to contact the pressure plate 51, the pressure sensor 52 will be squeezed by the pressure plate 51 and send an electrical signal to the control panel 2. The control panel 2 will immediately turn off the fan 313 and the motor 38 after receiving the electrical signal from the pressure sensor 52 to prevent the hose 314 from being blocked and causing the fan 313 to be damaged. When the slider 41 gradually approaches the pressure plate 51, the pressure plate 51 will push the connecting rod 54, and then the connecting rod 54 will push the pressure rod 53, so that the pressure rod 53 slides downward on the inner wall of the slider 41. During the downward sliding process of the pressure rod 53, the limit plate 56 will be pressed downward, so that the limit plate 56 gradually slides outward on the inner wall of the dust collecting cover 33 and pulls the limit spring 58. At the same time, the limit plate 56 will drive the limit rod 57 to gradually move away from the ring 3121, so that the limit rod 57 can be gradually moved out from the inside of the limit hole 55. When the limit rod 57 is completely moved out of the limit hole 55, the limit on the ring 3121 will be released. At this time, the ring 3121 can be removed from the dust collecting cover 33, so that the staff can deal with the impurities blocked at the connection between the hose 314 and the dust collecting cover 33.
