Cotton seed precision seeder for saline and alkaline land

Abstract

The invention discloses a cotton seed precision seeder for use on a saline and alkaline land and belongs to an agricultural machine. The structure of the seeder comprises a traction frame, a seed seeding box, a fertilizer spreading box, an earthing shovel, a press wheel, a mulching film roll and a ground wheel, wherein the bottom of the front end of the traction frame is provided with a mould board; the lower part of the seed seeding box is provided with a seeding plate; the lower part of the seeding disc is provided with a seeding tube and a front furrowing blade; the lower part of the fertilizer spreading box is provided with a spreading plate; the lower part of the spreading plate is provided with a rear furrowing blade; the rear part of the rear furrowing blade is provided with a spreading tube connected with the spreading plate; the middle part of the front side of the mulching film roll is provided with a shoveling and film covering shovel which gradually extends to the upper part of the mulching film roll from the front to the back; two sides of the shoveling and film covering shovel are provided with turnips; and the shoveling and film covering shovel is connected with a supporting rod on the traction frame through a connecting rod. The cotton seed precision seeder for use on the saline and alkaline land has the characteristics of preventing the mulching film from being blown off and damaged, promoting the germination and growth of the seeds and the like.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a precision sowing machine for cotton seeds in saline-alkali land. Background technique [0002] The use of plastic film in agricultural production has some advantages: increasing temperature and moisturizing; promoting the growth and development of crop roots; promoting the decomposition of organic matter in the soil; reducing soil loss; maintaining and improving soil fertility; it can promote early growth of crops and increase yield. Therefore, plastic film cultivation technology has been widely promoted and applied in rural areas. But now the cotton seed precision sowing machine used by people is sowing cotton seeds and when laying mulch, they just use the soil covering shovel on both sides of the tail of the cotton seed precision sowing machine to scoop up the soil and cover the sides of the mulch film with soil. However, when the wind blows, the soil covered on both sides of the m...

But now the cotton seed precision sowing machine used by people is sowing cotton seeds and when laying mulch, they just use the soil covering shovel on both sides of the tail of the cotton seed precision sowing machine to scoop up the soil and cover the sides of the mulch film with soil. However, when the wind blows, the soil covered on both sides of the mulch film is not enough to hold the mulch film down, and the wind will blow the mulch film up, destroying the mulch film and affecting the germination and growth of seeds.

Currently, there is no good solution
