The application method (working principle) of the invention is as follows:
before ground crushing, the loosener body 4 is driven by the shrinkage of the push rod at the inner side of the hydraulic cylinder II 5 to rotate clockwise to a state shown in fig. 1, at the moment, the outer side of the movable box II 83 is in contact with the top end of the loosener body 4, the top end of the loosener body 4 is enabled to extrude the whole abutting plate assembly 8, and when the top end of the loosener body 4 is communicated with the water spraying assembly 11 through the water pipe 10, namely, the top end of the loosener body 4 extrudes the abutting plate assembly 8, water between the movable box I82 and the movable box II 83 is sprayed out of the water spraying assembly 11 through the water pipe 10, then the ground to be crushed is wetted through water spraying, dust emission is reduced, after the water sprayed out of the nozzle is intercepted by the top end inclined plane of the water spraying assembly 11, the water flows downwards through the inner wall of the water spraying assembly 11, and accordingly flows to the outer side of the loosener body 4, and the surface of the loosener body 4 is wetted.
When the ground is crushed, the loosener body 4 is changed from the state shown in fig. 1 to the state shown in fig. 2, the loosener body 4 rotates circumferentially to crush and penetrate into the ground, dust is raised in the rear of the loosener body 4 in a unidirectional manner, in the process of crushing the ground by the loosener body 4, a push rod at the inner side of a hydraulic acting hydraulic cylinder II 5 stretches out and pushes a push rod 6, meanwhile, a sliding plug rod 12 slides upwards at the inner side of a plug cylinder 13, the plug cylinder 13 is in a state of sucking water from a water tank of a cab assembly, namely, a water spraying assembly 11 which is directly communicated with a water flowing pipe 14 does not flow out, the push rod in the hydraulic cylinder II 5 pushes the push rod 6, the loosener body 4 rotates relative to a hinge point between the push rod 6 and a hinge point between the bucket rod 2, the abutting plate assembly 8 is continuously extruded in the rotation of the loosener body 4, oil at the inner side of the hydraulic cylinder II 5 enters between a fixed plate 81 and a movable box I82 through a through an oil pipe 9, the water between the fixed plate 81 and the movable box I82 and the movable box II 83 are synchronously extruded, and then in the crushing process, the water is continuously sprayed to the rear of the movement of the loosener body 4 through a water spraying assembly 11 close to the resisting plate assembly 8, so that the water spraying nozzle in the water spraying assembly 11 can pertinently reduce unidirectional dust in the rear of the loosener body 4 in the rotary crushing process, simultaneously, the outer side of the resisting plate assembly 8 directly contacts with the top end of the loosener body 4, the hydraulic pressure of oil entering between the fixed plate 81 and the movable box I82 can directly act on the top end surface of the loosener body 4 through the resisting plate assembly 8, the top end of the loosener body 4 is directly driven by the force exerted by the resisting plate assembly 8, the interaction force between the loosener body 4 and the hinge point of the pushing rod 6 is reduced when the loosener body 4 is driven, the hinged shaft and the side plates hinged between the loosener body 4 and the pushing rod 6 are protected.
In the ground is broken in the rotation of the loosener body 4, the loosener body 4 is driven to rotate by the bucket rod 2 driven by the hydraulic cylinder I3 simultaneously, in the anticlockwise rotation of the bucket rod 2 relative to the bucket arm 1, the loosener body 4 is driven to be driven by the hydraulic cylinder II 5, and when the loosener body 4 moves to the state shown in fig. 2, the loosener body 4 does not vertically displace relative to the ground but only laterally displaces relative to the ground, and at the moment, the top end of the loosener body 4 still contacts and extrudes with the outer side of the retaining plate assembly 8 until the loosener body 4 is driven by the bucket rod 2 and the pushing rod 6 to be out of contact with the outer side of the retaining plate assembly 8, the retaining plate assembly 8 follows the bottom end surface of the pushing rod 6 to rotate to the outer side of the top end of the loosener body 4, and at the moment, the pushing rod in the hydraulic cylinder II 5 stretches out to the maximum length relative to the hydraulic cylinder II 5.
When the ground is broken by the loosener body 4 and leaves the ground, the bucket rod 2 is driven by the hydraulic cylinder I3 to drive the loosener body 4 to rotate anticlockwise relative to the bucket arm 1, then the bucket rod 2 is driven by the hydraulic cylinder I3 to open the bucket arm 1 and the bucket rod 2 again, the bucket rod 2 drives the loosener body 4 to rotate clockwise relative to the bucket arm 1 to gradually move to be in the state shown in figure 1, meanwhile, when the loosener body 4 leaves the ground, the front and rear broken stone blocks are pushed to move, dust is generated in the front and rear of the loosener body 4, oil in the inner side of the hydraulic cylinder II 5 is recovered by an oil tank through an oil pump in a cab assembly, namely, oil between the movable box I82 and the movable box II 83 is also recovered, namely, a push rod in the inner side of the hydraulic cylinder II 5 returns to the inner side of the hydraulic cylinder II 5, the sliding plug rod 12 can extend back to the inner side of the plug cylinder 13 again, the sliding plug rod 12 pushes water sucked into the inner side of the plug cylinder 13 to fill between the movable box I82 and the movable box II 83 through the water filling pipe 15, so that the movable box II 83 slides to the maximum distance to the outer side relative to the movable box I82, excessive water can be sprayed out through the water spraying component 11 close to one side of the resisting plate component 8, and the water inside the plug cylinder 13 can be directly sprayed out from the water spraying component 11 close to the bottom end of the bucket rod 2 through the water filling pipe 14, so that the two water spraying components 11 can simultaneously spray out water, dust in the front and back of the loosener body 4 is reduced, and in the process that the loosener body 4 leaves the ground, the higher the height of the loosener body 4 lifted relative to the ground is, the sprayed water can be sprayed to the circumferential ground of the loosener body 4 more uniformly, the dust reducing effect is better, and the construction process of construction staff is helped.
