The utility model relates to the field of beating machines, in particular to a beating
machine capable of improving soil hardening, and aims to solve the technical problems that in the prior art, a beating
machine and a
subsoiler are designed in a split mode, frequent disassembly and
assembly are needed when different operations are carried out, and time is wasted. The hydraulic support is connected with a hydraulic lifting
system of a traction vehicle, a deep
scarification shaft is rotatably connected in the hydraulic support in front of the beating shaft, the upper ends of a plurality of deep
scarification shovels are connected to the deep
scarification shaft at equal intervals, the middle of each deep scarification
shovel is connected with a rotating rod, a
hydraulic cylinder telescopic end is rotatably connected to the rotating rod, and a
hydraulic cylinder fixed end is rotatably connected to a fixed rod. The two ends of the fixed rod are connected between the hydraulic supports on the two sides, in the subsoiling process, the subsoiling shovels are controlled to deform to be in a working state, a non-grouted
paddy field is subsoiled, the pulping knife breaks cakes turned out by the subsoiling shovels to play a rotary
tillage role, after grouting, the pulping knife conducts pulping operation, and the subsoiling shovels are controlled to deform to be in a contraction state so that advancing of a traction vehicle can not be hindered.
