When all the screened agglomerated hard objects are crushed, the rest is stones, and for the hard objects with the determined stones, when the roller ball 205 is pressed on the stones, the roller ball 205 is lifted to be different in height, so that the V-shaped rods 304 are separated from the two side rods 204, and the V-shaped rods 304 are driven to move downwards by rotating the screw rods 305, so that the V-shaped rods 304 are attached to the two side rods 204 on the same side, and at the moment, when the sliding seat 206 is pressed downwards, the V-shaped rods 304 can be driven to press the two side rods 204, and then the two arc-shaped V-shaped cylinders 201 are opened, so that the stones enter the two arc-shaped V-shaped cylinders 201 for internal collection;
after the two arc-shaped V-shaped barrels 201 are closed, stones cannot fall out, and the stones can be continuously thrown into the two arc-shaped V-shaped barrels 201 to be collected until all the stones are discharged.
As shown in fig. 3:
The lower end of the preparation box 101 is fixedly connected with a base 102 to support the device, the bottom of the preparation box 101 is detachably connected with a bottom cover 103, a collection box is placed on the base 102, and after the bottom cover 103 is detached, fertilizer is discharged from the preparation box 101 and falls into the collection box to be collected;
The rear end of the preparation box 101 is connected with a water tank 104; the water is injected into the water tank 104, a plurality of high-pressure water sprays are arranged at the lower end of the water tank 104, water can be sprayed on the fertilizer for hard fertilizer which is difficult to crush, so that the soaked fertilizer is low in overall hardness, the soaked fertilizer is convenient to crush, meanwhile, stone-like foreign matters are not changed even if the water sprays the water, the device can better distinguish stone from caking materials, meanwhile, the fertilizer with high hardness is softened under the action of water spraying, then the fertilizer is crushed, and the stone foreign matters are left to be collected and treated independently.
