Description

The utility model belongs to the agricultural engineering industry, namely to disk working bodies and can be used for surface cultivation of soil and on erosive soils with surface water erosion.

The well-known analogue (Patent No. 95213, published in 07/11/2011, bull. No. 13), contains a disk mounted on the frame with the possibility of rotation. Part of the arc of the cutting edge of the disk is additionally equipped with a flat supporting scarf of low pressure on the soil.

The disadvantages of the analogue is that when processing light soils, the low-pressure supporting scarf falls into the soil and does not fulfill its purpose - the formation of a bridge. Under a supporting kerchief, the soil falls through, storing a continuous gap-channel-void for a moving stream of water, which washes away humus, soil, and so on. When treating heavy soils, each time the supporting headscarf is rolled onto the soil surface and the disk is lifted on duty to the headscarf and rolled over the jumper that has been formed, a jerky short-term increase in force occurs for the tillage machine, which leads to a pulsating violation of the optimal engine operating mode and excessive fuel consumption. The pulsating lifting of the disk to the soil surface is accompanied by accelerated wear of the device for ensuring its movement in the vertical plane and, accordingly, leads to an increase in operating costs to ensure its operability.

A useful model is the task to improve the disk working body of a tillage machine by changing the design.

The task is achieved in that the disk working body of a tillage machine containing a cutting edge, according to the proposed solution, consists of two separate parts, each of which has a solder and a cut on the cutting edge, while a gap is formed between the parts of the disk working body.

An example of the implementation of the disk working body of the tillage machine is explained by the drawings, where in FIG. 1 shows a disk working body of a tillage machine - side view, in FIG. 2 - a component of the disk working body, FIG. 3 - general view.

The working body of the tillage machine consists of two parts of the disk 3, axis 1, on which two parts of the disk 3 are mounted with soldering 6 on the edge for wear resistance, the base of the disk 2, slices 4, slots for mounting 5.

During movement, the working body of the tillage machine is in two functional states: 1 - action on the soil of the cutting edge (surface) of the parts of the disk 3 and the formation of a jumper in the recess-slit-void-channel depth from the edge of the edge with solder 6 to the base of the disk 2; 2 - the formation of a jumper between the space of two parts of the disk 3.

In the first state, parts of the disk 3 with solder 6 for wear resistance cut (process) the soil layer with its mass and additionally the force of the hydraulic cylinder, which is mounted on the frame when the disks are assembled into the battery, performing a reverse movement with loosening the soil to a depth from the edge of the solder 6 to the base disk parts 3.

In the second state, a jumper is formed due to the free passage of soil between the parts of the disk 3, which have sections 4, which eliminate a jerky short-term increase in traction (slipping), which leads to a pulsating violation of the optimal mode of engine operation and excessive fuel consumption.

Thanks to such implement implementations, manufacturing, maintenance (replacement of parts) technology is simplified, wear resistance is increased, and during its operation, the disk, performing a reverse movement, has significantly lower resistance to passing through the soil, which reduces the traction resistance of the working body, and eliminates the possibility of slipping during the formation of a recess - cracks-voids-channels.

The technical solution of the disk working body of the tillage machine is that it increases the erosion resistance of the surface of the soil treated by the aggregate, eliminating the processes of formation and movement of the surface runoff of atmospheric precipitation during heavy rainfall or heavy snowmelt, eliminating the movement outside the field: the fertile soil layer (humus), leaving most of it in place in a static state, pesticides and agrochemicals, and reduces fuel consumption, increasing the life of the engine.
