Problems solved by technology

[0004] The crushing effect and efficiency of the above two patents need to be further improved to better meet the needs of agricultural production; because the auger drill rod bears a large torque in deep plowing and deep loosening, the transmission output shaft and the drill rod adopt flanges, etc. Commonly used connection methods, affected by processing technology, etc., it is difficult for the axes of the two to be on the same straight line, causing swings, and the connection parts are easily damaged due to loose connections, and the reliability needs to be improved.

Embodiment 1

[0025] refer to figure 1 , figure 2 Shown, a kind of spiral drill bit for deep plowing and deep loosening comprises drill rod 1, helical blade 2, drill tip, connector, powder ridge cutter 4, and described helical blade 2 is fixed on the drill rod 1, and described drill tip is fixed on the drill bit. Rod head 5, the powder ridge cutter 4 is fixed on the outer edge of the spiral blade 2, the connecting part includes an inner polygonal sleeve and a fastener, the outer side of the transmission output shaft end 7 and the drill pipe end 8 are provided with The outer polygonal structure matched with the inner polygonal set of the connector, and the inner polygonal set is fixedly connected by a fastener. During installation, first match the inner polygonal set with the outer polygonal structure of the drill pipe end 8 and the transmission output shaft end 7, and then lock the inner polygonal set with fasteners.

[0026] The inner polygon set is a regular polygon set. Such as regul...

Embodiment 2

[0034] The difference from Embodiment 1 is that in this embodiment, the auger bit for deep plowing and deep loosening, the connecting piece of the transmission output shaft end 7 and the drill pipe end 8 also includes an outer polygonal sleeve 13, and the transmission output shaft end 7 , The inner side of the drill pipe end 8 is provided with a polygonal structure 14 cooperating with the outer polygonal sleeve 13, one end of the outer polygonal sleeve 13 is inserted into the transmission output shaft end 7, and the other end is inserted into the drill pipe end 8. This structure enables the connection between the drill pipe 1 and the transmission output shaft to withstand greater torque, so as to improve the life of the drill pipe and the transmission output shaft.

Abstract

The invention discloses a deep-plowing deep-scarifying spiral bit, comprising a drill rod, a spiral blade, a drill tip, a connecting piece and a crushing / ridging knife, wherein the spiral blade is fixed on the drill rod; the drill tip is fixed at the head part of the drill rod; the crushing / ridging knife is fixed at the outer edge of the spiral blade; the connecting piece comprises an inner polygonal sleeving piece and a fastening piece; an outer polygonal structure matched with the inner polygonal sleeving piece of the connecting piece is arranged at outer sides of the end parts of a transmission output shaft and the drill rod; and the inner polygonal sleeving piece is fixedly connected by virtue of the fastening piece. The deep-plowing deep-scarifying spiral bit disclosed by the invention is convenient to connect, has a good fixing effect, is accurately coaxial, and achieves good torsional moment resistance and stability; soil is crushed and shaped at one time during plowing; the cutting ability of the bit and the soil crushing effect of a crushing / ridging machine are increased; the convenience in dismounting, mounting and maintenance and the miniaturization of the structure are realized; and moreover, the deep-plowing deep-scarifying spiral bit is simple in structure and good in stability, and has relatively good structural stability and operation safety.

Description

technical field [0001] The invention relates to the field of agricultural tillage machinery, in particular to an auger bit for deep plowing and deep loosening. Background technique [0002] In the Chinese utility model patent whose authorized notification number is CN 204119753 U, an integrated rotary tillage and fertilization device for a flip-type subsoiling cultivator is disclosed, which includes a box body, a drive mechanism, more than two drill shafts, and a drill rod. shafts connected to the drill pipe and the transmission mechanism; the drive mechanism is installed on the box body and drives one of the drill pipe shafts to rotate, the drill pipe shaft is installed on the box body, and the transmission mechanism is arranged between adjacent drill pipe shafts; The drill shaft is a hollow shaft, the upper end of the drill shaft has a material inlet connected to the drill shaft, the drill rod has a cavity connected to the inside of the drill shaft, and the drill rod is pr...
