Device for longitudinal transplanting oilseed rape pot seedling in groove

Abstract

The invention discloses a device for longitudinal transplanting an oilseed rape pot seedling in a groove. A rack is provided with a transmission; the transmission is connected with a planter and a soil holding device, wherein the planter and the soil holding device are installed on the rack; a furrower, a soil pushing device, a seedling guidance device and a seedling conveying cup assembly are installed on the rack; a side surface is provided with a plantation groove; the planter carries out longitudinal reciprocating type transplantation in the plantation groove; the oilseed rape pot seedlingis implanted in the backfill soil in the plantation groove, transplantation speed is effectively improved, and high efficient plantation is realized; a seedling pushing plate in the planter rotates around an own small angle while carrying out horizontal seedling pushing for preventing backward seedling and soil throwing during high-speed horizontal transplantation; horizontal and longitudinal transplantation is cooperated with the soil covering way of the soil holding plate to generate an effect on simulating manual transplantation and soil holding, and young seedling transplantation qualityis effectively improved; a cam is adopted to control a seedling conveying cup opening and closing mechanism so as to effectively improve seedling falling accuracy and row spacing consistency; a slippage shifting gear is adopted to form a three-gear regulation function of sparse row spacing, middle row spacing and close row spacing so as to adapt to the requirements of the oilseed rape plantation density of different parcels of rice field.

Description

technical field [0001] The invention relates to the technical field of agricultural planting machinery, in particular to a device for vertically transplanting pot seedlings of rapeseed in a groove. Background technique [0002] Compared with rapeseed planting, the row spacing of rapeseed is uniform, the plants are strong, and the lodging resistance is strong; and the transplanting method can effectively stagger the growth cycle of different crops in the field, which is conducive to the realization of multiple crop rotation planting. For example, double-cropping rice is widely planted in the middle and lower reaches of the Yangtze River. The harvesting period of late rice is early to mid-October, and the planting period of early rice is early to mid-May. Olive rape is widely planted in the middle and lower reaches of the Yangtze River. Usually in mid-September, the harvest period is in mid-May of the following year. Therefore, it is difficult to use the method of sowing and p...

Problems solved by technology

For example, double-cropping rice is widely planted in the middle and lower reaches of the Yangtze River. The harvesting period of late rice is early to mid-October, and the planting period of early rice is early to mid-May. Olive rape is widely planted in the middle and lower reaches of the Yangtze River. Usually in mid-September, the harvest period is in mid-May of the following year. Therefore, it is difficult to use the method of sowing and planting to adapt to the planting mode of rice-rice-oil; Raising seedlings in seedling fields, transplanting rapeseed after the harvest of late rice to increase the growth overlap of the two crops and achieve multi-season crop rotation

[0003] At present, the planting density of rapeseed is usually above 130,000 plants / ha, with high density, small row and plant spacing, and high soil humidity and viscosity in southern paddy fields. Therefore, the existing hanging cup or seedling tube transplanting machine is used. Transplanting rapeseed has low work efficiency and poor adaptability
