Abstract

The invention relates to agricultural machinery and can be used in cultivators for tillage in a series of plants. The purpose of the invention is to improve the quality of tillage in the protective zone of a number of plants by reducing the damage of the latter and reducing the spread of soil. The rotary working body of the cultivator includes an inclined axis 1, on which disk 2 is mounted and rotatably mounted. On the periphery of disk 2, curved teeth 3 are fixed. Each tooth 3 is curved along a helical line. The working end of the tooth 3 is directed in the direction opposite to the direction of rotation of the disk 2. The angle α between the tangent to the surface of the tooth and the axis of the disk 1 is equal to the angle of inclination of the disk to the horizontal plane. 3 il.

The invention relates to an agricultural machinery industry and can be used in cultivators for treating soil, for example, in rows of tilled crops.

The purpose of the invention is to improve the quality of tillage in the protective zone of a number of plants by reducing the damage of the latter and reducing the spread of soil.

Fig 1 shows a rotary working body, rear view; FIG. 2 is the same side view; FIG. 3 is the same, top view.

The working body of the cultivator contains an axis 1 mounted obliquely in a direction transverse to the direction of movement of the vertical plane. On axis 1c: disk 2 is mounted with rotation, a tooth 3 is fixed on the periphery of disk 2,

Each tooth 3 is made in the form of a detachment of the helix. Together, the tooth forms a cylindrical surface, the axis of which coincides with the inclined axis 1 of the working body. The working horse of each tooth 3 is directed in the direction opposite to the direction of rotation of the disk 2. The angle cl between the tangent to the helix along which the tooth 3 is directed and the axis 1 is equal to the angle jj of the inclination of the disk 2 to the horizontal plane,

For tillage, a rotary tool is mounted on a section of a cultivator with an inclination of axis 1 in the direction of a number of plants. As the cultivator moves across the field, the disc 2 rotates to engage the teeth 3 with the soil. Tooth 3 thanks, their curvatures along the helix and the corresponding slope enter the soil at an acute angle.

At the moment of the greatest penetration of the tooth 3, it is positioned at an angle (90 of) relative to the line of portable movement of the disk 2,

Installing the teeth with an angle of about (relative to the direction of axis 1 equal to the angle of inclination of the disk 2 to the horizontal plane ensures close to the vertical position of the working ends of the teeth 3 at the time of their exit from the soil.

The shape of the teeth of the working body and their spatial arrangement also reduces the clogging of the working body, the removal of the soil from the furrow and its displacement away from the row, which is especially noticeable at elevated processing rates.
