Abstract
The utility model relates to a seeder seeds wheel transmission mechanism, in particular to a seeder seeds wheel four-bar linkage transmission mechanism. The utility model comprises a land wheel shaft, a seeding wheel shaft, a long bar and two short bars forming a four-bar linkage mechanism with the land wheel shaft and the seeding wheel shaft; wherein two ends of the two short bars are respectively and fixedly connected with the land wheel shaft and the seeding wheel shaft, both ends of the long bar are respectively provided with a bearing, the other ends of the two short bars are respectively provided with a pin roll matched with the bearing, and the long bar is connected with the two short bars through the bearing structure formed by the bearings and the pin rolls. Compared with the current four-bar linkage mechanism, because the transmission bars are connected through the bearing structure, the utility model avoids the forced friction among the transmission bars, ensures the flexibility and stability of the four-bar linkage mechanism and extends the service life of each part of the mechanism.
Description
Technical field:
The utility model relates to sower seed actuation, and especially a kind of sower seed is taken turns four bar-link drive.
Background technology:
At present, the miniature seeding machine seed is taken turns by land wheel by chain or quadric chain transferring power.Influenced by operating environment, the chain drive running is bad, the fault rate height; The quadric chain transmission can overcome the defective of chain drive, and the connected mode but bearing pin that is adopted between the drive link in the existing quadric chain and hinged axis hole are lived but exists rigid friction problem, and not only the drive link rapid wear also can cause rotating clamping stagnation when serious.
Summary of the invention:
The purpose of this utility model is intended to solve drive link rapid wear in the existing quadric chain, rotates the problem of clamping stagnation, and provides a kind of sower seed that adopts bearing arrangement to connect to take turns four bar-link drive.
The technical scheme that realizes the foregoing invention purpose is: a kind of sower seed is taken turns four bar-link drive, comprise land axle, sowing wheel shaft, form a stock and two quarter butts of quadric chain with described land axle and sowing wheel shaft, one end of two quarter butts is fixedlyed connected with the sowing wheel shaft with land axle respectively, bearing is equipped with at the stock two ends respectively, the other end of two quarter butts is equipped with the bearing pin with described bearing coupling respectively, is connected by the bearing arrangement of this bearing with the bearing pin formation between stock and the quarter butt.
Take turns four bar-link drive according to the sower seed that this case provides, compare with existing quadric chain, owing to adopt bearing arrangement to connect between the drive link, therefore avoided the rigid friction problem between drive link, guarantee the flexible, stable of quadric chain transmission, prolonged the service life of parts.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing:
A kind of sower seed is taken turns four bar-link drive, constitute by land axle 1, sowing wheel shaft 2, clamp nut 3, quarter butt 4, bearing 5, bearing pin 6, stock 7, split pin 8, described land axle 1, sowing wheel shaft 2, stock 7 and two quarter butts 4 are formed quadric chain, in this quadric chain, one end of a quarter butt 4 and land axle 1 welding are fixing, one end of another quarter butt 4 is provided with through hole, and by this through hole and clamp nut 3 with sow wheel shaft 2 and fixedly connected, this syndeton is convenient to change seeding wheel.Bearing 5 is equipped with at stock 7 its two ends in this mechanism respectively, and the other end of above-mentioned two quarter butts 4 is equipped with the bearing pin 6 with bearing 5 coupling respectively, is connected by the bearing arrangement of this bearing 5 with bearing pin 6 formations between stock 7 and the quarter butt 4.For preventing that bearing pin 6 from taking off axle, split pin 8 is housed in bearing pin 6 ends.
