Abstract
The utility model discloses a silent planting arm for a hand-held seedling planting machine. The silent planting arm comprises a planting arm body, wherein the upper end of the planting arm body is provided with seedling needles and a seedling pushing device; the rear end of the seedling pushing device is hinged with an extrusion arm which can control the seedling pushing device to pass in and out; the other end of the extrusion arm is hinged with a roller; a cam which is in driving connection with roller is arranged at the position on the planting arm body close to the roller; and a return spring is arranged between one side of the planting arm body close to the seedling pushing device and the extrusion arm. The silent planting arm adopts a manner that the cam is constantly meshed with the extrusion arm through the roller, is smoothly operated without noise, and is returned in the operating state by means of the return spring. The structure is in smooth transition, so that the noise and vibration are greatly reduced, and the service life of corresponding movement parts is prolonged.
Description
Technical field
The utility model relates to a kind of transplanter planting arm, relates to a kind of hand transplanting machine specifically with noiseless formula transplant arm, belongs to the agricultural equipment technical field.
Background technology
The structure of transplanter planting arm commonly used is as shown in Figure 1 at present; Comprise transplant arm body 1; The upper end of said transplant arm body 1 is provided with seedling pin 2 and seedling pushing device 12; The rear end of said seedling pushing device 12 is hinged with the extrusion arm 8 of controlled seedling pushing device 12 turnover, near the position that extrudes arm 8 the other end cam 7 is installed on the said transplant arm body 1, and the end of said extrusion arm 8 and cam 7 are in transmission connection; The crank 5 that is in transmission connection with cam 7 is installed on the said transplant arm body 1, and the lower end of transplant arm body 1 is connected with fork 6.Be provided with gland 3 near the position that extrudes arm 8 rear sides on the said transplant arm body 1, between gland 3 and extrusion arm 8, be equipped with and extrude spring 13, be provided with cushion pad 11 near the position that extrudes arm 8 front sides on the said transplant arm body 1.
During work, when cam 7 when extruding the contacting of arm 8, make seedling pushing device 12 move backward; When cam 7 when extruding arm 8 and not contacting, will extrude arm 8 extrusion through extruding spring 13, make seedling pushing device 12 travel forward and rice shoot released; But in use; When extrusion spring 13 will extrude arm 8 extrusion, often appearance extrusion arm 8 and cushion pad 11 clashed into excessive and produce and vibrate and noise, cause the early stage damage of corresponding parts.
The utility model content
The problem that the utility model will solve provides smooth-going, the noiseless hand transplanting machine of a kind of motion with noiseless formula transplant arm.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of hand transplanting machine is with noiseless formula transplant arm; Comprise the transplant arm body; The upper end of said transplant arm body is provided with seedling pin and seedling pushing device, and the rear end of said seedling pushing device is hinged with the extrusion arm of controlled seedling pushing device turnover, and the other end of said extrusion arm is hinged with roller; Be equipped with and the roller cam that is in transmission connection near the position of roller on the transplant arm body, said transplant arm body is near a side of seedling pushing device and extrude between the arm back-moving spring is installed.
Below be the further improvement of the utility model to such scheme:
Be provided with cushion pad near the position that extrudes the arm front side on the said transplant arm body.
Further improve: on the said transplant arm body crank that is connected with cam drive is installed, the lower end of transplant arm body is connected with fork.
Further improve: be provided with gland near the position that extrudes the arm rear side on the said transplant arm body, on gland, be provided with oil filler plug.
During work, cam and roller often mesh, and when cam rotates salient point promotion roller, make seedling pushing device travel forward, and rice shoot is released, and when cam rotated concave point, back-moving spring promoted to extrude the arm return.
The utility model adopts cam and extrudes the mode of arm through the normal engagement of roller, and smooth-going, the noiselessness that turns round is in working order during return; Realize through back-moving spring; Because of its structure for seamlessly transitting, so noise and vibration decline to a great extent, thereby the service life of having improved the corresponding sports parts.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
