Planting mechanism of front inserted-type oilseed rape transplanter

Abstract

The invention discloses a planting mechanism of a front inserted-type oilseed rape transplanter. The planting mechanism of the front inserted-type oilseed rape transplanter comprises speed reduction boxes, cam opening mechanisms, planting arm components and planters, wherein the speed reduction boxes are installed on the input shafts of the planters. The planting mechanism of the front inserted-type oilseed rape transplanter is characterized in that the two speed reduction boxes are symmetrically installed at two ends of the planters; each speed reduction box is provided with three output shafts; two output ends at one sides of the speed reduction boxes are connected with the planting arm components, and the output ends at the other sides of the speed reduction boxes are connected with the cam opening mechanisms; the tail ends of the planting arm components are symmetrically provided with two planters through shafts; and the planters are controlled to drop seedlings by the cam opening mechanisms. The device completes the functions of punching synchronously in four lines and transplanting oilseed rape seedlings once; the front inserted-type arrangement ensures that the whole machine is more compact, and reduces the planting leakage rate; and the mechanism has the characteristics of low seedling damage ratio, low seedling embedment ratio and low seedling leakage ratio, high seedling erecting ratio, conforming to the agricultural technology requirement of oilseed rape transplanting and the like.

Description

technical field [0001] The invention belongs to an agricultural planting machine, in particular to a planting mechanism of a front-inserted rapeseed transplanter. Background technique [0002] The transplanting management of rape seedlings is relatively fine, which is conducive to the cultivation of strong seedlings. It is an important way to cultivate "winter strong spring hair" and "winter spring double hair" rape to achieve high yield. It is to solve the contradiction between rice harvest and rape planting in southern paddy fields. It is the most important and even the only way to increase the multiple cropping index of rapeseed, and the rapeseed after transplanting is not easy to lodging, and can effectively avoid natural disasters such as drought, rain, snow and frost at the seedling stage. Rapeseed transplanting requires bending over, which is a labor-intensive agricultural activity. However, for a long time, rapeseed has been transplanted manually, which is not only l...

AI Technical Summary

Problems solved by technology

According to the agronomic requirements of rapeseed transplanting, four rows of rapeseed seedlings need to be transplanted on a single ridge, and the row and plant spacing of rapeseed seedlings are relatively small. However, the row spacing of rape seedlings cannot be guaranteed, which increases the time for turning the machine head, reduces the efficiency of transplanting, and increases the number of times the wheels crush the soil, which is not conducive to protecting the soil structure.
