Abstract
The utility model discloses a connection device between a shift fork and a sprouts pushing rod of the planting arm of a trans-planter, which comprises a connection plate, wherein, both ends of the connection plate are respectively hinged with a shift fork and a sprouts pushing rod by a pin roll. The utility model solves the problems of collision between the shift fork and the sprout pushing rod, easy abrasion and noise generation in the process of operation.
Description
Technical field
The utility model relates to a kind of transplanter planting arm, relates in particular to a kind of shift fork of transplanter planting arm and jockey between the transplanting rod of being used for.
Background technology
Transplanter planting arm is the core component of rice transplanter, and it is installed on the big arm of planting, and under the drive of drive unit, several transplant arms are realized seedling taking and pushed away the seedling operation with the big arm of planting.Known a kind of transplant arm, being equipped with one in the transplant arm housing can be around the shift fork of fixed axis swing by power-actuated cam and one, and an end of shift fork relies on the cam surface of cam, the other end and transplanting rod flexibly connect, and are provided with spring between the corresponding site of shift fork and transplant arm lid; Transplanting rod stretches out the pilot hole of transplant arm housing and is fixed with in its end and pushes away the seedling pawl, the external stability of transplant arm housing is connected with a seedling pin, it is a metal rod that is bent into U-shaped, form an elongated slot between two parallel shank portions of this seedling pin, in seedling taking, when pushing away seedling, this elongated slot is used to hold rice shoot, is called the seedling groove, and the bearing of trend of seedling groove is consistent with the direction of motion of transplanting rod.During the cam forward rotation, because the radius of cam surface increases gradually, thereby can make the shift fork swing, and then drive transplanting rod and move up vertically, this moment, rice shoot entered in the seedling groove of seedling pin, finished the seedling taking operation; When cam went to the breach of its cam surface, spring promoted shift fork and swings in the opposite direction, relied on the elastic deformation of spring that transplanting rod is moved down rapidly vertically, pushed away the rice shoot release that the seedling pawl will be positioned at the seedling groove, realized pushing away the seedling operation.
Move along fixed axis in order to make the shift fork swing time can drive transplanting rod, transplanting rod and shift fork must flexibly connect.Such structure is adopted in this flexible connection usually, peg graft in the initial end that is shift fork and transplanting rod, and be respectively equipped with the upper and lower nut that is threaded with transplanting rod in the upper and lower both sides of shift fork, upper and lower nut is used to limit shift fork moving axially on transplanting rod, and can the micro-link position of regulating shift fork and the initial end of transplanting rod.Because transplanting rod is when pushing away seedling, the lower surface that is fixed in the lower nut of the initial end of transplanting rod can collide the upper surface of the fairlead that is installed on guide part, produces rigid collision thereby make between shift fork and the transplanting rod, accelerates mutual wearing and tearing, also produce noise, shorten their service life.
The utility model content
Technical problem to be solved in the utility model provides a kind of shift fork of transplanter planting arm and jockey between the transplanting rod of being used for, and to solve in the course of the work, produces collision between shift fork and the transplanting rod, weares and teares easily, produces the problem of noise.
For solving the problems of the technologies described above, the technical solution of the utility model is: be used for the shift fork of transplanter planting arm and the jockey between the transplanting rod, comprise connecting plate, it is hinged that the two ends of described connecting plate are passed through a bearing pin and shift fork and transplanting rod respectively.
After having adopted technique scheme, the beneficial effects of the utility model are: because described jockey comprises connecting plate, it is hinged that the two ends of described connecting plate are passed through a bearing pin and shift fork and transplanting rod respectively, so in the course of the work, between shift fork, connecting plate and the bearing pin, and between transplanting rod, connecting plate and the bearing pin, has only pivoting friction, it is little to wear and tear, shift fork and transplanting rod can not produce bump, do not produce noise, thereby have improved the service life of each parts.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
As shown in drawings, be used for the shift fork of transplanter planting arm and the jockey between the transplanting rod, comprise connecting plate 8, it is hinged that the two ends of described connecting plate 8 are passed through a bearing pin and shift fork 5 and transplanting rod 6 respectively.In the course of the work, between shift fork 5, connecting plate 8 and the bearing pin, and between transplanting rod 6, connecting plate 8 and the bearing pin, have only pivoting friction, it is little to wear and tear, and shift fork 5 can not produce bump with transplanting rod 6, does not produce noise, thereby has improved the service life of each parts.
Described connecting plate 8 has two.Make connection more firm, more difficult generation noise, the service life of having improved each parts.
Claims (2)
1. be used for the shift fork of transplanter planting arm and the jockey between the transplanting rod, it is characterized in that: comprise connecting plate (8), it is hinged that the two ends of described connecting plate (8) are passed through a bearing pin and shift fork (5) and transplanting rod (6) respectively.
2. the shift fork of transplanter planting arm and the jockey between the transplanting rod of being used for as claimed in claim 1, it is characterized in that: described connecting plate (8) has two.
