Abstract

The invention relates to agricultural machinery, in particular, to pre-sowing leveling devices, and can be used for pre-sowing leveling and preparing the soil for sowing in a single technological process. The purpose of the invention is to improve the operational reliability of equalizers, reducing energy intensity. When moving planing working bodies 2 cut off the soil at a predetermined depth and move it into a roll. The augers 3 pick up the soil from the roll and feed it to the front sections of the 5 paddle throwers, with which it spreads along a flat surface. A pruning knife with a surface 8 cuts off the soil with irregularities formed during the operation of the throwers in the center of the treated strip and feeds the soil to the sidewalls 9, which displace the cut soil layer to the rear sections of the 6 throwers. As a result, the entire soil is leveled and covered with a loose mulch layer across the width of the machine. 2 Il.

The invention relates to agricultural machinery, in particular, to pre-sowing leveling devices, and can be used for pre-sowing leveling and preparing the soil for sowing in a single technological process.

The purpose of the invention is to improve the operational reliability of equalizers, reducing energy intensity.

FIG. 1 shows a soil equalizer, side view; in fig. 2 - the same, top view.

The soil leveler consists of a frame 1, on which planning working bodies 2, screws 3, mounted on shafts 4, and sections 5 and 6 of paddle throwers, which are connected to shaft 4 by means of horizontal hinges 7, are installed at an angle to each other. A slotting knife with a dumping surface 8, having an angle arranged to the direction of movement of the sidewall 9, is installed behind the throwers perpendicular to the longitudinal axis of symmetry of frame I.

The blades of the rear sections of the 6 throwers are bevelled at an angle of installation of the knife to the horizontal plane. The shafts of rotation 4 are arranged parallel to the longitudinal axis of the frame. For a more uniform distribution of the loose mulched soil layer along the leveled surface, a supporting plank roller R) is installed behind the pruning knife, the slats of which are placed at an angle to the axis of the roller, which makes it possible to level the mulched soil layer during its movement.

Soil equalizer works as follows.

When moving, planning working bodies 2 cut off the soil to set. 1 depth, and move it to WA, hook, laid on the raw strip formed between the planning working bodies. The augers 3 pick up the soil from the roll and feed it to the front sections of the 5 paddle throwers, with which it spreads along a flattened surface.

A pruning knife with a surface 8 cuts the soil with unevenness.

formed during the operation of the throwers, in the center of the treated strip and feeds the soil to the sidewalls 9, which shifts the cut soil layer to the rear sections of the 6 throwers. As a result of the joint action of the planning workers, undercutting the knife with the blade surface 8 and the throwers, the entire soil is leveled and covered with a loose mulched layer across the width of the machine.

Due to the large flow area formed by the planning workers, the location of the screws parallel to the longitudinal axis of the machine eliminates the clogging of the working bodies with plant residues when processing the soil surface with stubble backgrounds, low-sourced peat peaks, which increases the operational reliability of the leveler and reduces energy consumption for the drive of augers and throwers.

In addition, the installation of augers with throwers parallel to the longitudinal axis of the frame greatly simplifies the drive kinematics, and the execution of throwing blades angled at the installation angle of the pruning knife reduces the drag prism, which also increases the reliability of the leveler.

Claims (1)

Invention Formula The soil leveler, containing planing tools mounted on the frame at an angle to the friend, and shneki located behind them, with scoops with blades, characterized in that, in order to increase the leveling reliability of the leveler, to reduce energy intensity, the leveler is fitted with perpendicularly longitudinal mounts the axes of symmetry of the frame by an undercutting knife with a moldboard surface arranged at an angle to the direction of movement of the sidewall, while the axes of rotation with throwers are parallel to the longitudinal axis of the frame, and the blades of throwers facing the waste surface are chamfered at the angle of the knife to the horizontal plane.
