Description

The utility model relates to forestry engineering, in particular, to devices for primary soil cultivation in forest clearings.

A disk plow body is known (Patent for Utility Model No. 210794 of the Russian Federation; IPC A01B 5/00; published on 04.05.2022), comprising a stand with an axis on which a spherical disk and an additional working element, which is a hyperboloid-shaped moldboard, the axis of symmetry of which is aligned with the axis of symmetry of the spherical disk, are freely mounted by means of bearings.

A disk plow body is known (Patent No. 2692556 RF; IPC A01B 5/00, A01B 17/00; published on 25.06.2019), comprising a stand with an axis on which a spherical disk is freely mounted on a bearing with an additional working element rigidly attached to it, which is a hyperboloid-shaped moldboard, the axis of symmetry of which is aligned with the axis of symmetry of the spherical disk. Adopted as a prototype.

The disadvantage of these disc bodies is that the quality of soil cultivation may decrease when the technological conditions of the disc plows (types and moisture of the soil, the depth of its cultivation, etc.) change due to the non-optimal impact of the additional working element on the soil layer.

The task that the utility model is aimed at solving is to ensure high quality soil cultivation in forest clearings using a disc plow body under various technological conditions of its operation.

This is achieved by the fact that in the disk body of the plow, containing a stand with an axis on which a spherical disk is freely mounted on a bearing with an additional working element rigidly attached to it, which is a hyperboloid-shaped moldboard, the axis of symmetry of which is aligned with the axis of symmetry of the spherical disk, according to the utility model, the additional working element is made of separate segments rigidly connected to each other.

Fig. 1 shows a diagram of a disc plow body with an additional working element made of separate segments.

The disk body of the plow (Fig. 1) contains a stand with an axis on which a spherical disk 5 is freely mounted on a bearing with an additional working element rigidly attached to it, which is a hyperboloid-shaped moldboard, the axis of symmetry of which is aligned with the axis of symmetry of the spherical disk 5, while the additional working element is made of separate segments 1-4, rigidly connected to each other.

The disc body of the plow works as follows.

Before starting to cultivate the soil, depending on the technological conditions of the disk plow operation, to ensure optimal interaction of the additional working element with the soil, it is adjusted by installing it on the disk body axis and rigidly connecting the necessary individual segments 1-4 together into a single hyperboloid-shaped moldboard, rigidly attached to the spherical disk 5, for example, individual segments 1-4, 1-3, 2-4 or 3-4.

When the disk plow moves, the spherical disk 5, interacting with the soil, rotates, cuts off the soil layer and feeds it to an additional working element rotating together with the spherical disk 5, the implementation of which in the form of a hyperboloid moldboard allows to freely, with minimal energy losses, accept the soil layer cut by the spherical disk 5 and ensure its gradual continuous turnover. After the turnover, the soil layer is placed on the unprocessed soil surface and is tightly pressed to it by the additional working element, which ensures its integrity. As a result, next to the cleanly created furrow there is a completely inverted soil layer in the form of a continuous strip.

When working with a disc plow in forest clearings with new technological conditions, for example, with a different type of soil or depth of its processing, other individual segments 1-4 of the additional working element are installed on the axis of the disc body, they are rigidly connected to each other into a single hyperboloid-shaped moldboard and rigidly attached to the spherical disk 5. The working process of the disc body of the plow is carried out in a similar manner to that described above.

This design of the claimed disc plough body allows for high quality soil cultivation in forest clearings under various technological conditions of its operation.
