Embodiment Construction

[0023] figure 1 It is a cross-sectional view of an embodiment of the present invention, the planting arm shell 1 and the planting arm cover 2 are fixedly connected together by screws 10, and a cavity for installing other components is formed inside it. Planting arm shell 1 and planting arm cover 2 are all made of metal material, compared with the planting arm cover of plastic material, not only improved the intensity of the planting arm shell that is made up of planting arm shell 1 and planting arm cover 2, make it not suitable for Damaged and broken, and anti-aging, long service life, avoiding the influence of temperature difference. A cam 3 and a shift fork 4 that can swing around a fixed axis are installed in the planting arm shell 1, and the cam 3 can be connected with a power input shaft. One end of the shift fork 4 leans against the cam surface of the cam, and the other end is hinged with the seedling pusher bar 5, or other flexible connection methods are possible. A ...

Abstract

The present invention discloses a transplating arm of transplanting machine. Its main technical key point is that an elastic supporting component is set between the contact positions of spring and transplanting arm cover; the seedling needle is equipped with a guideway, the extension direction of said guideway is identical to the movement direction of seedling-pushing bar, the seedling-pushing end portion of seedling-pushing jaw is extended into the guideway interior. Said seedling needle is made up by using metal sheet bent component; the transplanting arm shell or transplanting arm cover is equipped with a recessed groove around its connection end face, in the recessed groove interior an elastic sealing ring is set, the height of cross-section of the described sealing ring is greater than the depth of the described recessed groove, and the seal between the connecting end faces of transplanting arm shell and transplanting arm cover is reliable.

Description

technical field [0001] The invention relates to the technical field of rice transplanting devices for rice transplanters, in particular to a planting arm of a rice transplanter. Background technique [0002] The planting arm of the rice transplanter is the core component of the rice transplanter, which is installed on the planting arm. Driven by the driving device, several planting arms and the planting arm together realize the operation of picking and pushing seedlings. In a known planting arm, a cam driven by power and a shift fork that can swing around a fixed axis are installed in the planting arm housing. One end of the shift fork is against the cam surface of the cam, and the other end is connected to the pusher A spring is provided between the shift fork and the corresponding part of the planting arm cover; the seedling pushing rod extends out of the guide hole of the planting arm shell and is fixed with a seedling pushing claw at its end, and the outside of the plant...
