Problems solved by technology

[0003] In the invention patent "Cylindrical tooth elliptical tooth planetary system splitting mechanism" with the authorized announcement number CN144203, there are 2 sets of planetary system gears arranged symmetrically relative to the sun gear in the gear box, driving 2 planting arms, and the gear box rotates once. The two planting arms each move once to achieve 2 hole

Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing and implementation.

[0025] As shown in Figures 1 and 2, the rotary splitting mechanism of the walking rice transplanter of the present invention includes transmission parts and planting arm parts. The transmission parts include a driving sprocket 18 mounted on the drive shaft 17 in the sprocket box 4, which is connected with the central sprocket 3 mounted on the central shaft 1 in the sprocket box 4 through a chain 19, and the central shaft 1 extends out of the sprocket box. 4 outer left and right side axle ends are respectively fixed with left and right gear box 5 ', 5. Left and right central gears 14', 14 fixed on the sprocket box 4 through left and right flanges 2', 2 are respectively housed on the central shaft 1 in the left and right gear boxes 5', 5, left and right , right central gear 14 ', 14 respectively by being installed on left and right intermediate shaft 12 ',...

Abstract

The present invention discloses a rotary transplanting mechanism of ambulating seedling transplanter. A central chain wheel in chain wheel box drives left/right gear boxes fixed to the two ends of central shaft. Fixed central gear meshes planetary gears fixed to planetary shaft by middle gears and planetary gears rotate with unequal speed relatively to gear box. A planting arm is fixed to an end of planetary shaft outside the said gear box, and its absolute motion is synthetic motion of unequal speed rotation of planetary gears relatively to gear box and circumferential motion of gear box relatively to shaft. The gear box is rotated through one cycle,and can make planting arms operating by once. So the said invention can be fitted for working frequency of ambulating seedling transplanter.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a rotary splitting mechanism of a walking rice transplanter. Background technique [0002] At present, the walking rice transplanter sold in the domestic and foreign markets, its planting mechanism is the crank rocker type sub-insertion mechanism. In China, rice is grown in double-cropping in the south and single-cropping in the north. When double-cropping rice is planted, the transplanted seedlings are larger and taller, and they are transplanted as large seedlings; when single-cropping rice is planted, the transplanted seedlings are relatively smaller and shorter, and they are transplanted as small seedlings. When the rice transplanter is transplanting large and small seedlings, the working trajectory curves of the seedling claws of the separate transplanting mechanism are different. Therefore, it is necessary to optimize the design of each structural parameter and motion parameter o...
