The initial position of the movable stop block 43 is the lowest part of the cutter head connecting piece 42 due to the action of the return coil spring 45; the inner cavity of the rotary hammer 46 is in a sleeved relation with the inner upper shaft of the transmission frame 41; the rotary hammer 46 is also connected to the inner upper shaft of the transmission frame 41 via a driving coil spring 47, and a driving coil spring groove 412 is used for mounting the driving coil spring 47. The driving coil spring 47 is vertically matched with the limit sliding groove 463 of the rotary hammer 46 in a sliding manner and is circumferentially locked, so that when the rotary hammer 46 and the transmission frame 41 are axially displaced, the external part of the driving coil spring 47 can slide in the limit sliding groove 463. The inner cavity of the rotary hammer 46 is also connected with the upper shaft in the transmission frame 41 by the matching protrusion 461 and the spiral guide groove 413 in a matching way, wherein the protrusion connecting rod 462 at the connection part of the matching protrusion 461 and the rotary hammer 46 is made of elastic material, the sphere center of the matching protrusion 461 is positioned in the spiral guide groove 413, and the edge thin wall part of the spiral guide groove 413 is made of elastic material, so that the matching protrusion 461 can be reliably matched with the spiral guide groove 413 in a sliding way in the transmission process, and when the relative acting force between the two is large enough, the deformation quantity of the edges of the protrusion connecting rod 462 and the spiral guide groove 413 exceeds the limit value, and the matching protrusion 461 is separated. As shown in fig. 9, the spiral guide groove 413 includes a lower cut groove 415 and a fitting groove 416, the cut groove 415 is a flaring structure, and the cut groove 415 is designed to better re-cut the fitting when the fitting protrusion 461 falls back to the initial position; the rebound tension spring 48 is arranged in the tension spring groove 414, the upper end of the rebound tension spring 48 is connected with the rotary hammer 46, and the lower end of the rebound tension spring 48 is connected with the transmission frame 41 and the rebound tension spring 48 is initially pre-tensioned to a certain extent.
In this embodiment, the height of the crushing cutter disc 33 gradually decreases from the middle to the outer edge, and preferably, the angle inclined from the middle to the outer edge ranges from 15 degrees to 45 degrees so that the wastes falling onto the crushing cutter disc 33 easily move to the outer edge of the crushing disc 45.
An environment-friendly irrigation and water conservancy project is for irrigation filth processing apparatus's concrete working process does:
the method comprises the steps of pouring dirt impurities and water into a feeding hole 11, enabling the dirt to fall on a crushing cutter disc 33, starting a driving motor 16 to enable a transmission frame 41 to drive the crushing cutter disc 33 to rotate, enabling a crushing cutter 31 and a crushing cavity 23 to jointly play a role under the centrifugal action to crush the dirt, enabling the crushed dirt to fall from the periphery of the crushing cutter disc 33 to a grinding protrusion 411 of the transmission frame 41 to be continuously ground with the crushing cavity 23 for the second time, then continuously falling, and finally discharging the crushed dirt from a discharging hole 17.
In the process of crushing and grinding the dirt, if a certain amount of dirt is accumulated on the upper end of the crushing cutter disc 33, because the transmission frame 41 and the crushing cutter disc 33 are in friction transmission, a certain rotation speed difference exists at the moment, the transmission frame 41 and the crushing cutter disc 33 have a certain relative rotation, the rotation speed of the crushing cutter disc 33 is reduced, and because the blocking part 431 of the movable stopper 43 is in abutting fit with the impact protrusion 464 on the rotary hammer 46, the rotary hammer 46 is matched with the spiral guide groove 413 through the matching protrusion 461, along with the relative rotation of the transmission frame 41, the rotary hammer 46 moves along the axial direction, the coil spring 47 is charged, the rebound tension spring 48 gradually stretches and charges, when the impact protrusion 464 rises to the outside of the blocking part 431 of the movable stopper 43, the rotary hammer 46 is released in rotation, because the elastic force stored in the coil spring 47 is greater than the acting force of the matching protrusion 461 staying in the spiral guide groove 413, the impact protrusion 464 breaks free from, the driving coil spring 47 and the rebound tension spring 48 rotate downwards under the action force together to finally fall into the bottom again, the impact protrusion 464 impacts the movable stop 43 to provide the crushing cutter disc 33 with the same impact force for steering, and the rotary hammer 46 continues the next impact process after falling to the initial position; the hammering movement is periodic hammering, and the larger the load or resistance on the crushing cutter head 33 is, the larger the speed difference between the transmission frame 41 and the crushing cutter head 33 is, the faster the relative movement is, the higher the hammering frequency is, and further the crushing efficiency is promoted.
In the process of crushing and grinding the dirt, if a large amount of dirt is suddenly accumulated at the upper end of the crushing cutter head 33 or the load is too large, the crushing cutter head 33 is suddenly stopped, the inertia ring 44 sleeved on the cutter head connecting piece 42 continuously rotates due to inertia to drive the movable stop block 43 to move upwards, the speed difference between the transmission frame 41 and the crushing cutter head 33 is very large due to the clamping of the crushing cutter head 33 during the period, the rotary hammer 46 follows to rise, at the moment, the transmission frame 41 needs to rotate more circles relative to the rotary hammer 46 to enable the impact protrusion 464 to rise out of the movable stop block 43, then the driving coil spring 47 can accumulate larger elastic force at the moment, after the releasing, the inertia ring 44 rapidly retracts due to the action of the reset coil spring 45, the movable stop block 43 rapidly falls down following, the impact protrusion 464 breaks away from the spiral guide groove 413, and rotates and moves downwards under the combined action force of the driving, finally falls into the bottom again, and the impact projection 464 impacts the movable stop 43, so that the crushing cutter disc 33 is provided with larger impact force with the same rotation direction, the clamping of the crushing cutter disc 33 is relieved, and the normal operation of the device is resumed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
