The utility model discloses technical scheme as follows:
a torsion type cotton picker spindle capable of automatically avoiding obstacles comprises a spindle picking head, a spindle picking rod, a long bolt, an obstacle avoiding spring and a sealing screw. The cotton picker is characterized in that 3 rows of hook teeth are arranged on the outer surface of the upper end of the spindle head, 10 to 12 hook teeth are arranged on each row, when the spindle rotates at a high speed, the hook teeth penetrate cotton fibers through spiral advancing, then the cotton is wound, the picking process of the cotton is realized, and an inclined groove is formed between each hook tooth and used for cotton stripping. The lower end of the spindle picking head is provided with a positioning hole, a threaded hole and an obstacle avoidance circular tooth, the edge on one side of the obstacle avoidance circular tooth is provided with a fillet, and the diameter of the fillet is 5-8 mm, so that the spindle picking head and the spindle picking rod can slide. The upper end of the spindle picking rod is provided with a positioning boss and obstacle avoidance square teeth, edges on two sides of the surface of the obstacle avoidance square teeth are provided with round corners, and the diameter of each round corner is not more than 1 mm and is used for realizing the sliding of an obstacle avoidance square tooth head and an obstacle avoidance circular tooth; the spindle picking rod is internally provided with a sealing screw hole, an obstacle avoidance spring hole and a long bolt hole, obstacle avoidance square teeth are meshed with obstacle avoidance circular teeth, a positioning boss is connected with a positioning hole, the positioning boss and the positioning hole are both conical, and the conical degree ranges from 2 degrees to 5 degrees; the sealing screw is arranged at the position of the sealing screw hole, the obstacle avoidance spring is arranged at the position of the obstacle avoidance spring hole, the long bolt penetrates through the obstacle avoidance spring and the long bolt hole to be connected with the threaded hole at the lower end of the spindle head, and the distance between the lower end face of the head of the long bolt and the lower end face of the sealing screw hole is 6-9 mm, so that the effective compression of the obstacle avoidance spring is guaranteed, and the obstacle avoidance is realized. Furthermore, the outer surface of the spindle head is covered with metal compounds (TiC, TiN and Al) with high hardness and high wear resistance2O3) Wherein said metal compound coating has a thickness of 2 microns to 6 microns.
Compared with the prior art, the beneficial effects of the utility model are that this structure can realize the effective barrier of keeping away of spindle, avoids the spindle to take place to collapse tooth, rupture in the course of the work, reduces the damage of spindle to the cotton stalk, can effectively reduce cotton picker's maintenance cost, and simultaneously, the first surface of spindle covers the maintenance cost of high rigidity, high wearabilityMetal compound (TiC, TiN, Al)2O3) The wear resistance of the spindle hook teeth is improved, the service life of a spindle is further prolonged, in addition, the structure adopts the conical positioning boss and the conical positioning hole, the self-centering effect is achieved, and the coaxiality of the spindle picking rod and the spindle picking head can be guaranteed.
