Multifunctional corn planter with seedling strip arrangement function

Abstract

The invention provides a multifunctional corn planter with a seedling strip arrangement function. The multifunctional corn planter comprises a traction frame, a hanging frame, a frame, a transmissionshaft, a gearbox, a stubble cleaning mechanism, a rotary tillage mechanism, a deep scarification fertilization mechanism, a sowing, ditching and compacting mechanism and an earthing mechanism, the transmission shaft is connected with the frame through the gearbox, the traction frame and the hanging frame are connected with the frame, the stubble cleaning mechanism comprises a stubble cleaning shaft, connecting sheets, a left knife blade and a right knife blade, the connecting sheets are arranged on the stubble cleaning shaft, the left knife blade and the right knife blade are connecting sheets, the rotary tillage mechanism comprises a rotary tillage shaft and rotary tillage teeth arranged on the rotary tillage shaft. According to the multifunctional corn planter with the seedling strip arrangement function, the frame is connected with a sowing and ditching mechanism through a four-bar spring mechanism, so that the corn planter can adapt different earth surface, consistency of sowing depths is ensured, respectively sowing from 1 row to 4 rows can be achieved by hanging and cutting off power, the corn planter can complete processes such ad stubble cleaning, rotary tillage earth-crushing, deep scarification, separated layer fertilization, ditching sowing, compacting and earth covering when working once and is applicable to corn sowing in plains, hills and mid-levels.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a multifunctional corn seeder for sorting seedlings. Background technique [0002] Whether the existing foreign corn precision seeder is mechanical or pneumatic, its structure is complicated and the cost is high, and it is mainly concentrated in the application of pneumatic precision seeder, while mechanical precision seeder is used less, which is not suitable for the main machine of agricultural machinery in our country. In my country, rural tractors are mainly medium and small, which are difficult to meet the power requirements; the existing domestic corn precision seeders are suitable for sowing large areas of flat land, relatively mountainous, mid-mountain, small plots, and complex land conditions. The sowing operation cannot guarantee the consistent sowing depth, resulting in poor sowing effect; the existing precision seeder still has problems such a...

Problems solved by technology

[0002] Whether the existing foreign corn precision seeder is mechanical or pneumatic, its structure is complicated and the cost is high, and it is mainly concentrated in the application of pneumatic precision seeder, while mechanical precision seeder is used less, which is not suitable for the main machine of agricultural machinery in our country. In my country, rural tractors are mainly medium and small, which are difficult to meet the power requirements; the existing domestic corn precision seeders are suitable for sowing large areas of flat land, relatively mountainous, mid-mountain, small plots, and complex land conditions. The sowing operation cannot guarantee the consistent sowing depth, resulting in poor sowing effect; the existing precision seeder still has problems such as concentrated fertilization, too deep rolling grooves by the pressing wheel, and segmental operation for stubble removal and subsoiling
