Reverse-rotation soil-clamping type dry land bowl-taking transplanting mechanism with Lagrange planetary gear train

Abstract

The invention relates to a reverse-rotation soil-clamping type dry land bowl-taking transplanting mechanism with a Lagrange planetary gear train and belongs to the field of agricultural machines. The mechanism comprises the non-constant-speed Lagrange non-circular gear planetary gear train composed of a planet carrier, a Lagrange non-circular solar gear, an intermediate gear and a planetary gear. A transplanting arm shell is fixedly installed on the Lagrange non-circular planetary gear, a cam, a poking fork, a compression spring, a seedling taking and pushing frame and a support are assembled on the transplanting arm shell, a seedling taking position adjusting plate of a hinged seedling needle set is fixedly assembled on the support, the seedling needle set is sleeved with the upper side portion of the seedling taking and pushing frame, and the planet carrier rotates anticlockwise. According to the mechanism, the seedling needle set is inserted into bowl body soil from the lower side portions of seedling bowls to clamp out the bowl seedlings from seedling trays, the bowl seedlings are directly transplanted into dry land soil, and the reverse-rotation soil-clamping type dry land bowl-taking transplanting mechanism has the advantages of being novel in structure, reasonable, simple, low in seedling-damage rate, good in operation quality and reliable to use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a transplanting mechanism used for transplanting pot seedlings in dry fields. Background technique [0002] In order to improve the yield per unit area and crop quality of upland crops, upland crop transplanting agronomic technology has attracted the attention of agricultural science and technology workers, and began to develop it. Efficient and high-quality transplanting equipment suitable for large-area upland crops is the key to the effective promotion of this agronomic method. The existing seedling-picking transplanting mechanism directly clamps the seedlings when taking the pot, and the soil pot body of the seedlings in the dry field is relatively large, which is very easy to cause seedling breakage accidents, especially when the seedlings are poorly fibrous, the seedlings are brittle, and the water content is high. The rate of broken seedlings is extremely high. The forward-...
