The invention discloses a composite-type powerful deep-loosening soil
pulverizer. The soil
pulverizer comprises a frame
assembly, a tripod arranged on the upper end of the frame
assembly, and an active box arranged among the tripod. A main transmission shaft is connected on the lower end of the active box. A transmission blade shaft is arranged on the upper end of the main transmission shaft. A screw box is connected on the lower end of the main transmission shaft. A screw
drill bit arranged parallel to the horizontal plane is connected on the outer end of the screw box. A screw box support plate used for fixing the screw
drill bit is arranged on the lower end of the frame
assembly on the side close to the screw
drill bit. According to the invention, the screw
drill bit is innovatively adopted. The screw
drill bit can drill forward with a taping state in a
deep level under the ground surface, such that deep loosening and deep
tilling are realized and soil layer resistance is minimized. The vertical transmission blade shaft can rotate transversally with a high speed to crush soil, thereby overcoming the defects that a deep-loosening
machine in the prior art forces forward in the soil rigidly and meets
high resistance and a back-rotary
tilling machine in the prior art has poor soil pulverizing performance. With the soil
pulverizer provided by the invention,
oil consumption can be minimized, efficiency is high, and soil pulverizing performance is high. The soil pulverizer is convenient and durable.
