Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] Such as figure 1 As shown, the power of the universal joint-driven inclined wide-narrow planetary gear train insertion mechanism of the present invention is transmitted from the first sprocket 1' to the second sprocket 1 through the chain, and the second sprocket 1 is fixed on the sprocket shaft 3 , the left and right transmission boxes with the same structure are respectively installed on both sides of the sprocket shaft 3, and the planting arms on the upper and lower sides of the left and right transmission boxes are installed; The output shaft 8 of the universal joint and the sprocket shaft 3 form an inclination angle, and the right end of the output shaft 8 of the right universal joint is fixedly connected with the right planetary carrier 6. In the right planetary carrier 6, the right sun gear 7 is supported on the output of the right universal joint through ...

Abstract

The invention discloses a universal joint-driven inclined wide-and-narrow separating-planting mechanism of a rice transplanter. Transmission cases of the same structure and planting arms of the same structure are arranged on the two sides of a chain wheel shaft respectively; the chain wheel shaft forms an inclination angle with an output shaft of a universal joint through the universal joint; the output shaft end of the universal joint is fixedly connected with a planet carrier; in the planet carrier, central gears are supported on the output shaft of the universal joint through bearings, are fixedly connected through flanges, adjustment gaskets and the flange on a transmission case body at the universal joint end and are connected with planet gears per se through idler wheels respectively; and planet gear shafts fixedly connected with the planet gears are connected with the planting arms per se respectively. In the universal joint-driven inclined wide-and-narrow separating-planting mechanism, seedling needles on the planting arms driven by the planet gears move in a plane inclined relative to the chain wheel shaft, the inclination of the planet carrier produces lateral movement relative to an advancing direction to move seedling inserting points leftwards or rightwards relative to seedling taking positions after the seedling needles take seedlings, and then rice transplantation positions are distributed in narrow and wide rows at unequal row spaces meeting agronomic requirements on the premise that seedling taking openings are distributed at equal intervals.

Description

technical field [0001] The invention relates to a splitting mechanism of a rice transplanter, in particular to a splitting mechanism of a universal joint-driven inclined wide and narrow row rice transplanter. 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, implanting them ...
