No-tillage seeder

Abstract

The invention aims to provide a no-tillage seeder. The no-tillage seeder comprises a rack, moving wheels, an air blowing mechanism, a fertilizing mechanism, a transmission case, a seeding mechanism, aditching mechanism and a rotary tillage mechanism, wherein the moving wheels are arranged on the front side of the rack; the air blowing mechanism, the ditching mechanism, the rotary tillage mechanism and the seeding mechanism are sequentially arranged at the bottom of the rack from front to back; the transmission case provides power for the air blowing mechanism, the rotary tillage mechanism, the fertilizing mechanism and the seeding mechanism; the rotary tillage mechanism comprises a rotating shaft and a plurality of groups of blades; the rotating shaft is in transmission connection with apower case; the plurality of groups of blades are distributed on the rotating shaft in the axial direction and are arc-shaped; ends of the blades bend and extend in the axial direction of the rotatingshaft to form bent parts; and the bending and extending directions of two blades in the same group are opposite. Soil loosening depth is increased by changing a soil rotating wheel provided with a toothed plate in the seeder into the arc-shaped blades, and meanwhile, the soil throwing phenomenon is avoided.

Description

technical field [0001] The invention relates to a seeder, in particular to a no-tillage seeder. Background technique [0002] With the continuous deepening of research on no-tillage seeders in my country in recent years, no-tillage seeder has developed rapidly. [0003] The invention patent with the patent number 201510014158.9 discloses a small no-tillage seeder for mountainous areas. Including the frame, it is characterized in that a seed box is arranged above the frame, a socket wheel seeder is arranged below the seed box, a seed guide tube is installed below the socket wheel seeder, and a straight plug is arranged on the frame The in-line hole sowing device is driven by the power input shaft, and the laminating wheel, the floor wheel, the soil rotation wheel, the ridging device, and the tension seat are successively installed under the frame. The rotation soil wheel is coaxially provided with The film sleeve is equipped with a conveyor belt on the frame above the rotar...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned no-tillage seeder has the following disadvantages: the rotary soil wheel of the seeder is a disc-shaped wheel body, and tooth plates are arranged on the peripheral side of the disc-shaped wheel body. Turn the soil to both sides of the ditch to form a ditch, and the rotary soil wheel rotates the soil along the track of the ditch to loosen the bottom of the ditch. When the above-mentioned soil rotary wheel loosens the soil, due to the size of the tooth plate Therefore, the soil loosening depth is relatively shallow, and the soil loosening effect is not good. In addition, the soil loosening method of the tooth plate is to throw the soil backward. Material feeding blockage, affecting seeding efficiency
