when the main hydraulic telescopic rod 5 contracts, the impact block 8 is driven to rise upwards, after the impact block 8 rises to a certain height, the impact sleeve 17 at the bottom is higher than the position of the ejector plate 18, at the moment, the impact block 8 moves upwards through the push rod 11 connected with the connecting sliding frame 12 and impacts the linkage ring 10, the linkage ring 10 drives all the connecting sliding rods 26 to slide upwards and rise, each connecting sliding rod 26 drives the connected rack 22 to rise in the sliding and rising process, the rising rack 22 drives the meshed linkage gear 23 to rotate clockwise, the coaxially connected cams 24 rotate synchronously, the protruding ends of the rotating cams 24 abut against the ejector plate 18, so that the main ejector plate 18 is pushed to move towards the central position of the inner side of the shielding cylinder 14, and as a plurality of ejector plates 18 are circumferentially distributed, the crushed stones at all positions of the edge in the shielding cylinder 14 can be pushed to the middle and gathered, so that the impact block 8 can be pushed to the middle again through the impact sleeve 17 to avoid that a part of the main hydraulic telescopic rod 14 shields the follow-up crushed stones and can not be impacted on the edge of the main hydraulic telescopic rod 14 continuously, so that the crushed stones can be pushed to be separated and gathered in the reciprocating movement, and the crushed stones can be driven to be crushed in the reciprocating movement, so that the crushed stones 8 can be crushed;
when ground crushed stones are required to be collected, the movable box body 1 is moved to a position above a crushed stone distribution area, then the third hydraulic telescopic rod 28 is controlled to extend downwards, so that the combined body of the U-shaped frame 44 and the movable bottom plate 30 descends along with the combined body, falls out from the feed port 33 and falls on the ground, the limiting rod 31 at one end of the movable bottom plate 30 vertically contacts with the inner wall of the feed port 33, meanwhile, when the movable bottom plate 30 descends to the ground, the movable bottom plate 30 is extruded onto the linkage plate 36, so that the linkage plate 36 descends synchronously through the telescopic connecting rod 37, so that the rotary columns 34 on the telescopic connecting rod 37 descend synchronously, and as the movable bottom plate 30 presses on the linkage plate 36, the pressure induction switch on the linkage plate 36 generates induction to start the driving motor 39, and the driving motor 39 drives the rotary columns 34 to rotate clockwise, the driving motor 39 scrapes the crushed stone on the ground through the distributed rubber scrapers 35 to push the crushed stone to the frame body enclosed by the U-shaped frame 44 and the movable bottom plate 30, when the frame body enclosed by the U-shaped frame 44 and the movable bottom plate 30 is filled with the crushed stone, the third hydraulic telescopic rod 28 is started to contract, so that the U-shaped frame 44 and the movable bottom plate 30 are lifted, and before the movable bottom plate 30 is lifted into the movable box body 1, the limiting rod 31 is in the vertical position and is abutted against the inner part of the feeding port 33, so that the movable bottom plate 30 is kept in the horizontal position to support the crushed stone, when the limiting rod 31 and the movable bottom plate 30 enter the movable box body 1 and are separated from the feeding port 33, the movable bottom plate 30 rotates to the inclined position due to the gravity action of the crushed stone, and simultaneously the limiting stop rod 29 is abutted against the movable bottom plate 30 due to the upward lifting of the movable bottom plate 30, the movable bottom plate 30 is ensured to be in an inclined position, so that broken stones can be conveniently poured into a storage space defined by the side baffle 32 and the inner wall of the movable box body 1, and the storage is convenient.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
