The lifter comprises an annular corrugation 47; an annular corrugated groove 47 is formed in the inner annular wall of the second annular groove 42; the connecting column 43 is provided with an L-shaped groove 48; an L-shaped column 49 is arranged in the L-shaped groove 48, one end of the L-shaped column 49 extends into the second groove 45 and is rotatably connected to the square block 46, and the other end of the L-shaped column is slidably connected to the annular corrugated groove 47; during operation, because the second gear 41 is driven to move through the connecting column 43, one end of the L-shaped column 49 moves up and down along the annular corrugated groove 47 in a fluctuating manner on the movement of the second gear 41, and then the L-shaped column 49 drives the square block 46 to move up and down in a fluctuating manner, so that the crushing of the pointed column 4 is driven, and meanwhile, the setting of the square block 46 can ensure that the pointed column 4 can still be driven to rotate without interference when the second gear 41 rotates.
A third groove 5 is formed in the middle of the impeller 12; the bottom of the third groove 5 is provided with a symmetrical distribution arc groove 51; the first rotating shaft 16 is rotatably connected to the side wall of the third groove 5; a fourth groove 52 is formed at one end of the first rotating shaft 16, which is close to the bottom of the third groove 5, and a fifth groove 53 is formed at the other end of the first rotating shaft 16; a moving plate 55 is slidably connected to the fourth groove 52; the fifth groove 53 is in threaded connection with a bolt rod 54, and one end of the bolt rod 54 extends into the fourth groove 52 and is fixedly connected to the moving plate 55; the position of the moving plate 55 relative to the arc-shaped groove 51 is fixedly connected with a clamping block 57 through an elastic telescopic rod 56; during operation, because some protection measures such as crashproof spare all consume the silt absorbing capacity of pump body 1, when opening, can lead to silt absorbing capacity itself to have certain decline, therefore in the desilting, there is not solid impurity in the silt in some cases, or when a small amount of, rotate bolt pole 54 this moment, clamping piece 57 breaks away from arc groove 51, later only impeller 12 rotates, filter screen 17 play filtering action can, there is not impurity to interfere this moment, but when solid impurity is too much in the silt, should rotate bolt pole 54 this moment, let movable plate 55 remove, drive clamping piece 57 get into arc groove 51, because of solid impurity is too much, the silt absorbing force body just needs to reduce this moment, so the internal energy that should reduce drives crashproof spare protects the operation, can make full use of internal energy, clamping piece 57 is through elastic telescoping rod 56 setting simultaneously, so when screwing up bolt pole 54, the moment need not guarantee that clamping piece 57 card enters arc groove 51, supposedly, can direct clamping rotation can be done in the direct clamping action, but when clamping piece 57 is unable to get into arc groove 51 at the moment, the clamping piece 54, the corresponding clamping piece 57 can be compressed mutually when rotating the clamping piece 51 when the clamping piece 54 is screwed up at the moment, the clamping piece is located at the moment, the corresponding arc groove 56, the mutual compression of clamping piece 57 can be accomplished.
The screwing direction of the bolt rod 54 is the same as the rotation direction of the impeller 12; in operation, the tightening of the bolt 54 drives the impeller 12 to rotate the first rotating shaft 16, so that when the tightening direction of the bolt 54 is the same as the rotating direction of the impeller 12, the tightening state of the bolt 54 can be ensured, and no loosening occurs.
Working principle: the pump shaft 13 can drive the impeller 12 to rotate, the impeller 12 rotates to feed sludge from the feed inlet 14, the discharge outlet 15 is discharged, the filter screen 17 is arranged at the feed inlet 14, some solid impurities can be separated, meanwhile, the filter screen 17 is arranged into an inverted cone shape, direct collision to the filter screen 17 under the strong suction force of the pump body 1 can be reduced, the flow can be continued along the inclined plane of the filter screen 17, the instant collision force can be reduced, the solid impurities can be removed, the solid impurities are prevented from being always attached to the filter screen 17, the feed efficiency is influenced, and meanwhile, in order to further reduce the collision condition, an anti-collision piece is arranged outside the filter screen 17, the solid impurities are effectively cleaned by the anti-collision piece, the normal use of the filter screen 17 is ensured, and the service life is prolonged; when the filter screen 17 rotates, the first annular rack 23 is driven to rotate, and the second annular rack 24 is not moved, so that the first gear 25 is driven to rotate around the first rotating shaft 16 while rotating, although the revolution directions of the filter screen 17 and the rotating column 22 are the same, the rotation speed of the filter screen 17 and the revolution speed of the rotating column 22 are different, the filter screen 17 is fast, the rotating column 22 revolves slowly, the two have speed differences, the rotating column 22 can protect different positions of the filter screen 17, the filtering and feeding states of the filter screen 17 are not influenced, solid impurities are generally collided with the rotating column 22 at first during working, and then thrown out, so that the collision frequency is effectively reduced; because some solid impurities are substances except stone, metal and other hard substances and are generally formed by gathering some agglomerated impurities, the protection plate 26 is arranged, and the saw tooth grooves 27 are arranged on the protection plate 26, so that the solid impurities can be thrown out and simultaneously broken by the aid of the saw tooth grooves 27, the solid impurities can be conveniently subjected to subsequent desilting operation (the thrown out impurities can be secondarily adsorbed by suction), and meanwhile, the saw tooth grooves 27 are very close to the filter screen 17, and can be used for carrying out segmentation cleaning on some plastic film thin-layer impurities; the rotating column 22 only reduces collision, but not completely avoids collision, so that a part of solid impurities can collide with the filter screen 17 and then flow along the inclined plane of the filter screen 17, and then the solid impurities flowing along the inclined plane of the filter screen 17 are subjected to rotating collision operation by the action of the pointed column 4 to be crushed and thrown out; because the second gear 41 is driven to move by the connecting column 43, one end of the L-shaped column 49 moves up and down along the annular corrugated groove 47 in a fluctuating manner on the movement of the second gear 41, and the L-shaped column 49 drives the square block 46 to move up and down in a fluctuating manner, so that the crushing of the pointed column 4 is driven, and meanwhile, the square block 46 can ensure that the pointed column 4 can still be driven to rotate without interference when the second gear 41 rotates; because some protection measures such as anti-collision parts consume the silt sucking internal energy of the pump body 1, when the anti-collision parts are opened, the silt sucking capacity can be reduced to a certain extent, so that during dredging, solid impurities are not existed in the silt at all times, or when a small amount of impurities exist in the silt, the bolt rod 54 is rotated, the clamping block 57 is separated from the arc-shaped groove 51, only the impeller 12 rotates in the later stage, the filter screen 17 plays a filtering role, no impurities interfere at the moment, but when the solid impurities in the silt are excessive, the bolt rod 54 is rotated at the moment, the moving plate 55 is moved to drive the clamping block 57 to enter the arc-shaped groove 51, and the silt sucking force body is reduced at the moment, so that the internal energy which is required to be reduced drives the anti-collision parts to perform protection operation, and the internal energy can be fully utilized.
