Composite-type powerful deep-loosening soil pulverizer

Abstract

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.

Description

technical field [0001] The invention relates to a combined powerful subsoiler. Background technique [0002] A driven soil tillage machine with rotating cutter teeth as the working part, also known as a rotary tiller. According to the configuration of the rotary tiller shaft, it is divided into two types: horizontal axis type and vertical axis type. Horizontal-axis rotary tillers with the knife shaft horizontally placed are widely used. Classification has a strong ability to crush soil. One operation can make the soil finely crushed, the soil and fertilizer can be mixed evenly, and the ground is flat, which can meet the requirements of dry land sowing or paddy field planting. . However, the ability to cover stubble and weeds is poor, and the plowing depth is relatively shallow (12-16 cm for dry farming; 14-18 cm for hydroponic farming), and the energy consumption is relatively large. Problems such as long span, large resistance, high fuel consumption, and difficult towin...
