Pot seedling transplanting device

Abstract

A pot seedling transplanting device comprises a rack, a compartment flattening device for flattening a soil compartment surface is arranged at the front end of the rack, and at least one group of hole forming devices for vertically extruding on the compartment surface to form seedling planting holes and at least one group of seedling falling devices for falling seedlings into the seedling planting holes at zero speed are sequentially arranged on the rack on the rear side of the compartment flattening device. And a transmission mechanism which is in driving connection with the compartment leveling device, the hole forming device and the seedling falling device is arranged on the rack. In the pot seedling planting process, hole forming uniformity and stability are high, hole forming and pot seedling falling are kept synchronous, the high requirement of a machine tool for soil and pot seedlings is met, and pot seedling planting uniformity and high efficiency of land utilization are guaranteed; the device is high in practicability, high in clay cavitation rate, not prone to missing planting and convenient to operate, labor force in the pot seedling planting process is liberated to a great extent, and the planting economic benefits of pot seedlings are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery rapeseed transplanting, and in particular relates to a pot seedling transplanting device. Background technique [0002] At present, rape is one of the most important oil crops in the world, and it is also the main source of edible oil in China; there are mainly two modes of planting rapeseed: direct seeding and transplanting; as the main winter rape producing area in China, the Yangtze River Basin has a planting area accounting for the total area of ​​the country. More than 85% of them mainly adopt the planting mode of rapeseed transplanting. Most of the rapeseed transplanting adopts pure manual labor operation, which has high labor intensity, large labor consumption, high production cost and low economic benefit. It is urgent to develop mechanized technology of rapeseed transplanting . [0003] Existing rapeseed transplanting machines mainly contain the following types: seedling-o...

Problems solved by technology

[0002] At present, rape is one of the most important oil crops in the world, and it is also the main source of edible oil in China; there are mainly two modes of planting rapeseed: direct seeding and transplanting; as the main winter rape producing area in China, the Yangtze River Basin has a planting area accounting for the total area of ​​the country. More than 85% of them mainly adopt the planting mode of rapeseed transplanting. Most of the rapeseed transplanting adopts pure manual labor operation, which has high labor intensity, large labor consumption, high production cost and low economic benefit. It is urgent to develop mechanized technology of rapeseed transplanting

[0003] Existing rapeseed transplanting machines mainly contain the following types: seedling-opening ditch-type transplanting machine, which can open a whole row of seedling ditch, but greatly reduces the porosity of the soil on the compartment surface, which affects the root growth and survival rate of rapeseed seedlings. Reduced; duckbill transplanting type transplanting machine, its vertical hole formation does not meet the requirements, affecting the uprightness of rape seedlings; soil-taking type transplanting machine, which has high requirements for loose and fine soil, is prone to missed planting; These machines have high requirements for loose and fine soil, seedling age and appearance, and are prone to missed planting, so it is difficult to meet the planting requirements for rapeseed transplanting.
