When the plurality of hammer bars 15 slide toward the sub-screen 27 , the soil clods with larger particles on the sub-screen 27 can be hammered to break them and facilitate them to fall from the sub-screen 27 .

[0039] A control assembly is provided inside the processing box 1, which is used to control the sliding of the hammer rod 15 through the movement of the processing box 9;

[0040] By means of the control assembly, the hammering rod 15 can be controlled to hammer the soil clods on the sub-screen 27 when the processing box 9 moves.

[0058] S2: The striking blade 13 is controlled to rotate by the first motor 14, so that the unbreakable stones can be struck into the receiving box 4 on the other side when the processing box 9 slides;

[0059] S3: The first bevel gear 19 is driven to rotate by the first reciprocating screw 12, so that the second bevel gear 20 drives the second reciprocating screw 21 to rotate, and the piston 23 can be driven to slide back and forth inside the piston cylinder 24 through the sliding rod 22, and cooperate with the water inlet pipe 26 and the water outlet pipe 25 to transport the water in the water tank 3 to the water spray pipe 6 to reduce dust.

[0060] Working principle: The rotation of the second motor 5 can drive the first reciprocating screw 12 to rotate, so that the slider 11 slides back and forth on the outer wall of the first reciprocating screw 12, and the processing box 9 drives the guide rod 8 on the connecting plate 7 to slide along the outer wall of the guide arc block 10. When the guide rod 8 slides to the top of the guide arc block 10, the connecting plate 7 will drive multiple hammer sticks 15 to slide upward inside the processing box 9, so that the tension spring is deformed. When the guide rod 8 slides to the depression between the two guide arc blocks 10, the connecting plate 7 will drive multiple hammer sticks under the potential energy of the tension spring. 15 slides downward and hammers the soil blocks on the sub-screen 27 to break the soil blocks, and the transmission gear 17 is driven to rotate by the first tooth plate 16, so that the second tooth plate drives the crushing nails 18 to slide downward, so as to assist the hammer rod 15 in breaking the soil blocks. The rotation of the first motor 14 can drive the striking blades 13 to rotate, and the stones that cannot be broken by the hammer rod 15 can be knocked toward the direction of the receiving box 4 by the rotating striking blades 13.

[0061] When the first reciprocating screw 12 is driven to rotate by the second motor 5, the second bevel gear 20 will drive the second reciprocating screw 21 to rotate, thereby realizing the reciprocating sliding of the slide rod 22.
