Abstract
The utility model discloses a forced pushing-seedling planting arm of a constant diameter cam type transplanter. A driving shaft of the planting arm is flexibly sheathed with a driving cylindrical gear; both a driven cylindrical gear and a constant diameter cam are 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 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 constant diameter cam and a roller rod form a constant diameter cam mechanism. The roller rod is a driven piece of the constant diameter cam mechanism and provided with two rollers with relative positions being not changed. When the constant diameter cam rotates, the outline of the constant diameter cam is always kept in contact with the two rollers, a rocker sliding block is driven by the roller rod to move, and a pushing-seedling rod is the sliding block. The cylindrical gear mechanism, the constant diameter cam mechanism and the rocker sliding block mechanism are adopted, the relative rotation movement of the driving shaft of the planting arm and the driving cylindrical gear is transformed to the regulated 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 constant diameter 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 constant diameter 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; Constant diameter cam and roller bar are formed constant diameter cam mechanism, and the roller bar is a constant diameter cam mechanism driven member, and two constant rollers of relative position are housed on it; When constant diameter cam rotates, the profile of constant diameter cam remains with two rollers and contacts, one end of the fork-shaped rocking bar of roller bar and slider-rocker mechanism is hinged, the fork-shaped rocking bar is supported on the fixed hinge point of transplant arm housing, the other end and the connecting rod of fork-shaped rocking bar are hinged, and the other end and the transplanting rod of connecting rod are hinged, and transplanting rod is exactly a slide block, transplanting rod is done straight reciprocating motion, and rice shoot on the seedling pin is pushed Tanaka.
The bar on the both sides of described fork-shaped rocking bar is long than being 1.5～2.5 times, and promptly the hinge point center is to the pin joint distance and the ratio of hinge point center to the pin joint distance of fork-shaped rocking bar and connecting rod of fork-shaped rocking bar and roller bar.
The gearratio of described active roller gear and driven cylindrical gear is 1: 1.
Adopt cylindrical gear mechanism, constant diameter cam mechanism and slider-rocker 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.
