Problems solved by technology

In the existing published literature on the transplanting mechanism of the rice transplanter, the needles on the planting arm of the existing transplanting mechanism only move in a plane parallel to the forward direction and perpendicular to the ground. Cannot form the wide and narrow row spacing seedling distribution required by agronomy

Embodiment Construction

[0019] The present invention will be further described below in conjunction with drawings and embodiments.

[0020] Such as figure 1 , image 3 As shown, it includes a transmission part and four planting arms with the same structure; the left and right ends of the central shaft 1 in the transmission part are fixedly connected with left and right gear boxes 3, 3' with the same internal structure, extending out the left and right gear boxes. Planting arms are respectively installed on four planetary shafts outside the right gear box 3,3 '.

[0021] The structure of the right gear box 3 is as follows: the right gear box 3 is fixedly connected with the frame through the right flange 2, the right sun gear 11 is installed in the right gear box 3 at the right end of the central shaft 1, and the upper right middle wheel 14 is installed on the upper right middle shaft 13 and upper right middle helical gear 12, lower right middle gear 10 and lower right middle helical gear 9 are insta...

Abstract

The invention discloses a split-transplanting mechanism of a transplanting machine for transmitting wide and narrow rows by a bevel gear. A set of crossed helical gears are respectively arranged in a left gear box and a right gear box with the same structure for transmission, a planet wheel and a middle bevel wheel are a pair of engaged crossed helical gears to ensure that a planet shaft and the gear boxes are inclined so that a planting arm fixedly connected to the planet shaft is inclined with the gear boxes; and a motion plane of a planting arm seedling pin is not parallel to a rotary plane of the gear boxes any more but performs space motion to form a space seedling-transplanting working track. The seedling pin moves to a seedling-pushing point position from a seedling-fetching position of a seedling door, a seedling pin point generates transversal displacement, i.e. the displacement vertical to the forwarding direction of the machine so that a seedling earth-penetrating point transversely moves to the left or to the right relative to the seedling-fetching position and seedling-transplanting row spaces form alternate distributions of wide and narrow rows of agriculture requirements under the premise of the traditional seedling door isometric distribution.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a splitting mechanism of a wide and narrow row rice transplanter driven by helical gears. Background technique [0002] Wide and narrow row transplanting refers to the implementation of one wide and one narrow planting method for the row spacing of rice transplanting. This planting method utilizes the principle of crop marginal advantage to increase production. By adjusting the row spacing of transplanting rice seedlings, the ventilation and light transmittance between plants can be improved, and diseases can be reduced. Increase the leaf area index, prolong the life of the leaves, and accelerate the accumulation of dry matter, so as to achieve the purpose of high quality and high yield, saving cost and increasing efficiency. [0003] The separate transplanting mechanism is a component on the rice transplanter that realizes taking seedlings, transplanting them, and planting the seedlings...
