Abstract
The utility model discloses a forced pushing-seedling planting arm of a conjugate cam type transplanter. A driving shaft of the planting arm is flexibly sheathed with a driving cylindrical gear; a driven cylindrical gear and a conjugate cam are all installed on a driven shaft; the driving cylindrical gear extends out of a planting arm shell, is in claw coupling with a separating-planting mechanism planet carrier and does not rotate with respect to the separating-planting mechanism planet carrier, and the shell of the planting arm is fixed on the driving shaft of the planting arm and does seedling-taking actions. The conjugate cam, a fork-shaped swing rod and two rollers fixed on the fork-shaped swing rod form a conjugate cam mechanism. The fork-shaped swing rod is a driven piece of the conjugate cam mechanism, one end of a hinge point fixed on the shell of the planting arm is contacted with a main cam and an accessory cam of the conjugate cam by the two rollers and the other end is contacted with a pushing-seedling rod. The cylindrical gear mechanism and the conjugate cam mechanism are adopted and the relative rotation movement of the driving shaft of the planting arm and the driving cylindrical gear is transformed to the liner reciprocating movement of the pushing-seedling rod, so that the pushing-seedling action is finished. The mechanism can be suitable to the operation of the transplanter under any rotation speed.
Description
Technical field
The utility model relates to rice transplanter, and what be specifically related to a kind of rice transplanter planetary gear train type transplanting mechanism pushes away the seedling transplant arm.
Background technology
The effect of transplant arm and pulling seedlings device is the blanket appearance seedling on the rice transplanter seedling case to be torn and it is pushed Tanaka's device.At present, the rice transplanter machine planetary gear train type transplanting mechanism transplant arm version and the pulling seedlings device transmission principle unanimity thereof of at home and abroad selling on the market, transplant arm and planetary gear are done the seedling taking action, pulling seedlings device in the transplant arm is done the straight reciprocating motion with respect to transplant arm: by plane cam, shift fork, transplanting rod and spring are finished seedling pushing action jointly, its version is simple, but can not adapt to different rotating speeds, when particularly operating speed changes greatly, the seedling concluding time often appears pushing away in advance or lag behind, this is that the length that pushes away the seedling time then is decided by the rigidity of spring owing to push away the profile that the time started of seedling is decided by cam.When rice transplanting speed is too slow, push away seedling in advance, lag behind otherwise push away seedling, this all causes the upright degree of rice shoot poor, influences turning green of rice shoot.And ordinary circumstance can not changed spring, so rice transplanter can only operation in certain velocity interval, and is poor to the adaptive capacity of speed.
Summary of the invention
The purpose of this utility model provides a kind of rice transplanter forced seedling-pulling transplant arm of conjugate cam type, and this mechanism can satisfy the rice transplanting requirement of rice transplanter, and can adapt to the operation under the transplanting machine at any rotating speed.
In order to achieve the above object, the technical solution adopted in the utility model is:
Transplant arm driving shaft of the present utility model is the transplanting mechanism planet wheel spindle, kink has initiatively roller gear on it, driven cylindrical gear and conjugate cam all are contained on the driven shaft, initiatively roller gear stretch out the transplant arm housing outer with the tooth embedding mutually of transplanting mechanism planet carrier, do not relatively rotate with the transplanting mechanism planet carrier, the transplant arm housing is cemented on the transplant arm driving shaft; Conjugate cam, fork-shaped fork and two rollers that are fixed on the fork-shaped fork are formed conjugate cam mechanism; The fork-shaped fork is the conjugate cam mechanism driven member, be fixed on the hinge point on the transplant arm housing, an end contacts with the main cam and the auxiliary cam of conjugate cam by two rollers, and the other end contacts with transplanting rod by an elongated slot, transplanting rod is done straight reciprocating motion, and rice shoot on the seedling pin is pushed Tanaka.
Described conjugate cam is made up of main cam and auxiliary cam, respectively by contacting with separately roller, the control transplanting rod push away seedling, withdraw and stop action.
The amplification coefficient of described fork-shaped fork is 1.5～2.5 times, and promptly the hinge point center is to the ratio of contact point distance with the distance of hinge point center to two roller centre of fork-shaped fork and transplanting rod.
The gearratio of described active roller gear and driven cylindrical gear is 1: 1
Adopt gear mechanism and conjugate cam mechanism, the relative rotary motion of transplant arm driving shaft and active roller gear is transformed into the regular straight reciprocating motion of transplanting rod.
The beneficial effect that the utlity model has is:
This mechanism can satisfy the rice transplanting requirement of rice transplanter, and can adapt to the operation under the transplanting machine at any rotating speed.
