DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present utility model.

[0018] Reference Figs. 1-3In this embodiment of the present invention, a contaminated soil crushing device includes a trailer 1, a mounting shaft 5 installed at the tail of the trailer 1, wheels 6 fixedly connected to both sides of the mounting shaft 5, a shovel 2 fixedly connected to the bottom front end of the trailer 1, multiple sets of equidistantly distributed fixed grid plates 7 fixedly connected to the bottom of the trailer 1, fixed frames 8 fixedly connected to both sides of the bottom of the trailer 1, fixed rods 9 fixedly connected between the fixed frames 8, sliding blocks 10 slidably connected to the fixed rods 9, a spring 17 sleeved on the fixed rods 9 between the sliding blocks 10 and the fixed frames 8, a vibrating frame 11 fixedly connected to the sliding blocks 10, multiple sets of equidistantly distributed sliding grid plates 12 fixedly connected inside the vibrating frame 11, and the sliding grid plates 12 slidably connected to the fixed grid plates 7.

[0019] An oscillation drive assembly is provided between the mounting shaft 5 and the vibration frame 11; a dragging assembly is provided at the front end of the tractor 1.

[0020] This invention connects the device to agricultural machinery via a towing assembly, allowing the machinery to move the device across the ground. During movement, the wheels 6 contact the ground, converting the friction between the wheels 6 and the ground into rotational driving force for the mounting shaft 5. The mounting shaft 5, through a vibration drive assembly, drives the vibration frame to reciprocate, causing the sliding grid plate 12 and the fixed grid plate 7 to slide back and forth. When the device needs to scoop up contaminated soil, the towing assembly controls the bucket 2 to press down and insert into the soil. Inside, as the trailer 1 moves under the traction of the agricultural machinery, the soil layer is scooped up and pushed into the trailer 1 by the bucket 2. At this time, the soil clods accumulate on the fixed grid plate 7 inside the trailer 1. Due to the irregular shape of the soil clods, the protrusions of the soil clods will insert into the gaps between the fixed grid plates 7. Then, under the action of the shearing force generated by the reciprocating motion between the sliding grid plate 12 and the fixed grid plate 7, the soil clods are sheared and broken. The broken soil falls back to the ground along the sliding grid plate 12, thus completing the fine crushing of the contaminated soil layer.

[0021] In one instance of this embodiment, please refer to Figs. 1-3 The oscillation drive assembly includes a connecting shaft 14 fixedly connected to the oscillation frame, a crankshaft 16 fixedly connected between the mounting shafts 5, one end of a rocker arm 13 rotatably connected to the crankshaft 16, and the other end of the rocker arm 13 rotatably connected to the connecting shaft 14. The oscillation assembly drives the connecting shaft 14 to rotate through the rotation of the wheel 6, and the connecting shaft 14 drives the crankshaft 16 to rotate. The crankshaft 16 drives the oscillation frame to reciprocate through the rocker arm 13.

[0022] In one instance of this embodiment, please refer to Figs. 1-3The dragging assembly comprises a mounting plate 3 fixedly connected to the top of the front end of the drag bucket 1, and a connecting arm 4 rotatably connected to the mounting plate 3, and the connecting arm 4 is connected to the agricultural machine.

[0023] In one case of the embodiment, please refer to Figs. 1-3 The connecting arm 4 is rotatably connected with a hydraulic telescopic pump 15, and the output end of the hydraulic telescopic pump 15 is rotatably connected to the mounting plate 3.
