Referring to fig. 1-5, a mud scraper for reducing collision and abrasion between agglomerated sludge and a mud scraper comprises a working bridge 1, the mud scraper 2 is fixedly mounted on the lower surface of the working bridge 1, the mud scraper 2 is obliquely arranged, the mud scraper 2 is composed of a mounting seat 20, a front plate 21, a front cavity 211, an air film 22, a communication rod 23, an elastic member 24, a rear plate 25, a rear cavity 251, an air guide hole 26, a transverse plate 27 and a sliding transverse plate 28, the mounting seat 20 is fixedly mounted on the lower surface of the working bridge 1, the front plate 21 is arranged on the right side of the mounting seat 20, the right side of the mounting seat 20 is fixedly connected with one end of the air film 22, the other end of the air film 22 is fixedly connected with the left side of the front plate 21, the front cavity 211 is enclosed by the right side of the mounting seat 20, the left side of the front plate 21 and the air film 22, the front cavity 211 is filled with air, the inner cavity of the mounting seat 20 is movably mounted with the communication rod 23, one end of the communication rod 23 is fixedly connected with the left side of the front plate 21, air guide holes 26 are equidistantly formed in the mounting seat 20, transverse plates 27 are fixedly mounted on the upper surface inside the air guide holes 26, sliding transverse plates 28 are slidably mounted on the lower surface inside the air guide holes 26, when the mud scraping plate 2 contacts agglomerated sludge, the front plate 21 is subjected to resistance and moves inwards due to the resistance exerted by the agglomerated sludge, gas in the front cavity 211 can be discharged through the air guide holes 26 in the moving process of the front plate 21, energy caused by collision between the front plate 21 and the agglomerated sludge is transferred through the discharged gas, abrasion caused by collision between the front plate 21 and the agglomerated sludge is reduced, then in the process that the gas passes through the air guide holes 26, the gas pushes the sliding transverse plate 28 in the middle position to open, and due to the asymmetrical arrangement of the transverse plate 27 in the current position and the sliding transverse plate 28, when the gas passes through the air guide holes 26 in the middle position, the pressure is uneven, so that the mounting seat 20 vibrates, and then drive the front bezel 21 vibration for front bezel 21 exerts a vibration thrust to the caking mud of contact, makes caking mud receive the vibration and breaks away from the bottom of the pool, and then reduces caking mud and to the resistance of mud scraper 2, reduces the wearing and tearing that mud scraper 2 and caking mud collide the produced.

Wherein, the left side of mount pad 20 is provided with back plate 25, the left side of mount pad 20 and the one end fixed connection of air film 22, the other end of air film 22 and the right flank fixed connection of back plate 25, the left surface of mount pad 20, the right flank of back plate 25 encloses into back chamber 251 with air film 22, the other end of intercommunication pole 23 and the right flank fixed connection of back plate 25, gas in the current chamber 211 is discharged the back from the gas guide hole 26 of middle part position, these gases can get into back chamber 251, and promote the outside removal of back plate 25, make the workspace of mud scraping plate 2 outwards remove, and then avoid producing the work dead angle between the adjacent mud scraping plate 2, influence the mud scraping effect.

Wherein, the left side inner wall of mount pad 20 inner chamber and the one end fixed connection of elastic component 24, the other end of elastic component 24 and the protruding piece fixed connection of intercommunication pole 23 can extrude elastic component 24 through intercommunication pole 23 when the inside removal of front bezel 21, and after caking mud breaks away from the bottom of the pool, the resistance that front bezel 21 receives reduces for elastic component 24 release elasticity, and then the front bezel resets around driving, with the smooth of the follow-up caking mud operation of clearing up going on of convenience.

Wherein, the number of the air holes 26 is three, the three air holes 26 are arranged from top to bottom, the installation directions of the transverse plate 27 and the sliding transverse plate 28 at the positions of the air holes 26 at the upper and lower sides and the transverse plate 27 and the sliding transverse plate 28 at the positions of the air holes 26 at the middle position are opposite, so that in the process of transferring the gas in the front cavity 211 to the rear cavity 251, the gas pushes the sliding transverse plates 28 at the upper and lower sides and the transverse plate 27 to close, and the sliding transverse plate 28 at the middle position is opened, thereby realizing the function that the agglomerated sludge is separated from the bottom of the tank, then, in the process of resetting the front and rear plates, the gas in the rear cavity 251 pushes the sliding transverse plates 28 at the upper and lower sides to open, and the sliding transverse plate 28 at the middle position is closed, so that the gas flows back to the front cavity 211 through the air holes 26 at the upper and lower sides, because the sliding transverse plates 28 and the transverse plates 27 at the upper and lower sides are asymmetrically arranged, the pressure of the gas is uneven, so that the mounting seat 20 drives the front plate 21 to vibrate, so that the sludge adhered on the front plate 21 is separated, and the sludge is prevented from being adhered on the front plate 21 and moving along with the mud scraping plate 2, so that the load of the driving device is increased, and further, the energy waste is caused.

Wherein, the fixed position below the right flank of front bezel 21 has the shovel piece, exerts a shear force through the shovel piece to caking mud and bottom of a pool adhesion department, and when front bezel 21 vibrated, the shovel piece vibrates simultaneously for caking mud is changeed and is broken away from the bottom of a pool.

The use method (working principle) of the invention is as follows:

when the sludge collecting device works, the driving device drives the working bridge 1 to rotate around the center of the sedimentation tank, so that the mud scraping plate 2 pushes the sludge at the bottom of the tank, and the sludge gradually flows to the central mud collecting groove along the bottom of the tank under the pushing of the mud scraping plate 2, when the mud scraping plate 2 contacts the caked sludge adhered to the bottom of the tank, the resistance applied to the mud scraping plate 2 by the sludge is received, when the resistance is received, the front plate 21 moves inwards and extrudes the elastic part 24 through the connecting rod 23, meanwhile, the front plate 21 extrudes the gas in the front cavity 211 into the gas guide holes 26, the gas pushes the sliding transverse plates 28 at the upper side and the lower side to be closed, the sliding transverse plate 28 at the middle position is opened, so that the gas enters the rear cavity 251 from the gas guide holes 26 at the middle position, and the pressure applied when the gas passes through the gas guide holes 26 at the middle position is uneven, so that the mounting seat 20 vibrates, and then drive the front plate 21 to vibrate, make the front plate 21 exert a vibrating thrust to the caking sludge that contacts, make the caking sludge be vibrated and break away from the bottom of the pool, at the same time, the gas that enters the rear chamber 251 pushes the rear plate 25 to move outwards, and then make the working area of the mud scraper 2 move outwards, after the caking sludge breaks away from the bottom of the pool, the resistance that the front plate 21 receives is reduced, make the elastic member 24 release the elasticity, and then drive the front plate 21 and the rear plate 25 to reset, in the process of resetting the front plate and rear plate, the gas in the rear chamber 251 pushes the upper and lower two sides sliding transverse plates 28 to open, and the middle position sliding transverse plate 28 is closed, make the gas flow back to the front chamber 211 through the upper and lower two sides gas guide hole 26, because the upper and lower two sides sliding transverse plates 28 and transverse plate 27 are asymmetrically arranged, make the gas receive the pressure, make the mount 20 drive the front plate 21 to vibrate, make the sludge adhered on the front plate 21 break away, this is one duty cycle.
