No-till seeder for saline-alkali soil

Abstract

The invention discloses a no-tillage planter applicable to saline-alkali soil. The no-tillage planter comprises a rack, wherein a sowing box is arranged on the rack, a rotary tiller is arranged in front of the sowing box on the rack, and a soil refining mechanism is arranged between the sowing box and the rotary tiller on the rack; the soil refining mechanism comprises a cover plate, the cover plate comprises a plane part at the middle part, curved parts are respectively connected with the two end parts of the plane part in an integrated manner, the height of the curved part at the front end is gradually reduced from front to back, and the height of the curved part at the rear end is gradually increased from front to back; the lower side of the cover plate is fixedly connected with a plurality of cutting blades which are vertically arranged side by side, each cutting blade comprises a straight section at the middle part, a front elliptic section is connected with the front end of the straight section in an integrated manner, a rear elliptic section is connected with the rear end of the straight section in an integrated manner, and an interval between every two adjacent cutting blades is 0.5 to 1 cm; and the cover plate completely covers the cutting blades. The no-tillage planter applicable to the saline-alkali soil can refine soil.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a no-tillage seeder suitable for saline-alkali land. Background technique [0002] The no-tillage seeder is a kind of agricultural equipment. The use of the no-tillage seeder can replace the original steps of manual sowing, fertilization and plowing, and can be completed in one step. It is specifically used in the sowing, Fertilization and tillage operations. It solves the problems of insufficient agricultural labor force and labor cost, and expands the agricultural planting area and mechanization level. [0003] The soil in saline-alkali areas is prone to compaction due to its high salt content. When the existing no-tillage seeder is used in saline-alkali areas, the compacted soil will form a lot of clumps after being turned over, which is not conducive to the growth of crops after sowing. Contents of the invention [0004] The technical problem to be solved b...

AI Technical Summary

Problems solved by technology

[0003] Due to the high salt content of the soil in the saline-alkaline area, the soil is easy to harden. When the existing no-tillage seeder is used in the saline-alkali area, the hardened soil will form a lot of lumps after being turned over, which is not conducive to the growth of crops after sowing.
