Planting device and planting method of fully automatic transplanting machine for rapeseed blanket seedlings

Abstract

The invention relates to a planting device for a rape blanket-shaped seedling full-automatic transplanting machine, wherein the planting device comprises a machine frame, and a soil-loosening and joint-cutting assembly, a soil covering press assembly and a planting arm which are fixedly arranged on the machine frame; the soil-loosening and joint-cutting assembly is fixed on a main beam of the machine frame, and joint-cutting and soil-loosening functional components are corrugated plates; the soil covering press assembly comprises a soil covering press bracket and a soil covering press wheel assembly; the soil covering press assembly adopts a lever structure to adjust a rotation angle of the soil covering press bracket along a horizontal rotation shaft, so as to preliminarily adjust the height of the soil covering press wheel assembly; the soil covering press wheel assembly is rotatingly fixed on the soil covering press bracket, and adjusts a rotation angle through a fixing mode of springs and limiting shafts, so as to precisely adjust the height of soil covering press wheels; the soil-loosening and joint-cutting assembly, the planting arm and the soil covering press assembly are arranged from front to back orderly. The planting device adapts to rape transplanting soil characteristics, solves problems of rape transplanting with soil and reliable seedling erecting under conditions that soil of a field after rice harvesting is high in viscosity and poor in liquidity, and improves the efficiency of rape transplanting in multiple times.

Description

technical field [0001] The invention relates to a planting device, in particular to a planting device of a fully automatic transplanting machine for rapeseed blanket seedlings, belonging to the technical field of rapeseed transplanting. Background technique [0002] Rapeseed is the most important oil crop in my country, with an annual planting area of ​​more than 7 million hectares and a total rapeseed output of more than 10 million tons, ranking first in the world. Rapeseed is an important source of edible vegetable oil in my country, accounting for 55% of domestic edible vegetable oil. The contradiction between the supply and demand of edible vegetable oil in my country is prominent, and now 65% depends on imports. Therefore, the development of rapeseed production is of great significance to ensure the safety of edible oil in our country. [0003] The Yangtze River Basin is the largest winter rapeseed area in the world and the most concentrated rapeseed production area i...

Problems solved by technology

[0008] The technical problem to be solved in the present invention is: the existing dry land transplanting machine is generally not suitable for the sticky and heavy soil after rice harvesting, and the state of finely broken, loose and flowable soil cannot be achieved by any means of plowing and land preparation, so it cannot meet this requirement. The soil conditions required for the operation of similar transplanting machines; the transplanting method of the transplanting machine for rice transplanting is to directly insert the seedlings into the wet and soft soil, and it cannot adapt to the sticky and heavy soil after rice harvesting; the existing semi-automatic naked The seedling transplanting machine has low operating efficiency, and the automatic pot seedling transplanting machine is too expensive for rapeseed transplanting, so it is not suitable for rapeseed transplanting
