Bevel gear-elliptical gear eccentric wheel rocking bar combined-type wide and narrow row spacing transplanting mechanism

Abstract

The invention discloses a bevel gear-elliptical gear eccentric wheel rocking bar combined-type wide and narrow row spacing transplanting mechanism. In the prior art, seedling taking of a conventional seedling taking and transplanting integrated vegetable pot seedling transplanting mechanism is realized via direct clamping of seedlings, so that seedling roots are damaged; seedling taking and transplanting are realized via two mechanisms, and the mechanisms are complex. Each of the two ends of a center shaft of the bevel gear-elliptical gear eccentric wheel rocking bar combined-type wide and narrow row spacing transplanting mechanism is provided with a first-grade planetary gear train, and the two first-grade planetary gear trains are arranged to be symmetrically; the two ends of each first-grade planetary gear train is connected with a second-grade upper planetary gear train and a second-grade lower planetary gear train; each second-grade upper planetary gear train is provided with an upper transplanting arm, and each second-grade lower planetary gear train is provided with a lower transplanting arm; each first-grade planetary gear train comprises a first-grade gear case, a center elliptical gear, a first-grade upper planetary elliptical gear, a first-grade lower planetary elliptical gear, a first-grade upper planetary shaft, a first-grade lower planetary shaft, an upper eccentric wheel, an upper connecting rod, an upper rocking bar, a lower eccentric wheel, a lower connecting rod, and a lower rocking bar. The bevel gear-elliptical gear eccentric wheel rocking bar combined-type wide and narrow row spacing transplanting mechanism can be used for realizing in-pot soil-taking-type seedling taking, and in seedling taking period, translational motion of seedling claws is maintained, so that pot soil completeness is maintained as far as possible.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a bevel gear-ellipse gear eccentric wheel rocker combined wide and narrow row transplanting mechanism which is suitable for automatic vegetable pot seedling transplanting and has the characteristics of integrated picking and planting. Background technique [0002] Vegetable planting in my country has a tradition of intensive farming. Due to the resource conditions of a large number of people and little land, it is determined that vegetable planting in my country needs to be combined with my country's economic and technological conditions to take a standardized and low-cost development path. Mechanized planting will become another dominant technology for the future development of vegetable planting in my country. [0003] The row spacing of the seedlings transplanted by the vegetable transplanter implements a planting method of one wide and one narrow. This planti...

Problems solved by technology

[0007] At present, the domestic research and development of the integrated automatic transplanting mechanism for vegetable picking and planting is basically imitation, and no major improvements and technological breakthroughs have been made to foreign transplanting machines, and foreign transplanting machines are complex in structure and expensive. And it is difficult to adapt to the agronomic requirements of our country, and it is very difficult to promote it in China
