Abstract

FIELD: agriculture; mechanical engineering.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to anti-erosion soil-cultivating devices. Device for cutting a water-absorbing slit with a simultaneous filling of it with straw contains a hinged frame, on which a sliver is successively fixed, two guides in the form of tine arms and a sealing working member in the form of a cut-out disk with an involute profile of the projections, connected to the frame by means of a parallelogram mechanism with the possibility of height adjustment, for its installation in such a way that only the protrusions enter the gap, and from the field surface to the disc depressions there is a distance equal to the stubble height of the field being processed.

EFFECT: such a constructive solution provides an improvement in the water-absorbing capacity of the slit by laying the straw in a slot with access to the surface of the field in the form of a micro-wings and with air space between the bottom of the slit and the straw.

Description

The invention relates to agricultural machinery and can be used for the treatment of soils susceptible to water erosion.

A device for cutting water-absorbing slots with simultaneous filling with straw, including a hinged frame, which is sequentially mounted slithere, two guides in the form of a rake and closing the working body, which is a circular disk attached to the frame by means of a parallelogram mechanism with height adjustment [1 ] (prototype).

The disadvantage of this device is that the straw embedded in the slot with a round disk is located at a certain distance from the field surface, that is, it does not strengthen the edges of the walls of the slot, as a result of which it closes, as a result of which the surface runoff does not penetrate into the lower soil layers.

The objective of the invention is to improve the water absorption capacity of the slit by laying straw in the slot with access to the field surface in the form of a micro-curtain and with the air space between the bottom of the slot and the straw.

The technical result is achieved by the fact that the device for cutting a water-absorbing slit while filling it with straw includes a hinged frame on which the slit is sequentially fixed, two guides in the form of a rake and a closing working body attached to the frame by means of a parallelogram mechanism with the possibility of height adjustment, and closing the working body is made in the form of a cut-out disk with an involute profile of the protrusions, which is installed so that only protrusions enter the slot, and from the field surface to the hollows of the disk there is a distance equal to the height of the stubble of the treated field.

The invention is illustrated by drawings. Figure 1 shows a device for cutting a water-absorbing slit while filling it with straw (side view); figure 2 - diagram of embedding straw in the slot with a cutting disc.

A device for cutting a water-absorbing slit consists of a hinged frame (1), on which slitherese (2) is sequentially fixed, two guides in the form of a rake (3) and a closing body, which is a cut-out disk (4) attached to the frame (1) by parallelogram mechanism (5) with adjustable height. Adjustment of the guides and the sealing disk in height is carried out using the adjusting devices (6) and (7), respectively. The tines (3) are installed at a certain angle to each other so that the straw is raked towards the slot when the unit moves.

The proposed device operates as follows. When the unit begins to move along the field, the hinged frame 1 is lowered, while the sloter 2 enters the soil to the required depth. Slitherez 2 cuts a gap in the soil, while the straw, which is previously crushed and scattered during harvesting on the soil surface, is collected by tines 3 and fed into the gap region. Next, the cut-out disc 4 closes the straw inside the gap. In this case, the straw is placed in the slot with access to the field surface in the form of a micro-curtain and with the air space between the bottom of the slot and the straw (Fig. 2).

Straw covered with such a device remains unchanged for a long time, keeping the soil from shedding, as a result of which surface runoff penetrates into the lower soil layers. At the same time, the air space between the bottom of the slit and the straw favors its release from excess water, which allows it not to freeze into a continuous monolith, but to continue to receive and let water through it. Also, due to the fact that there is a distance from the surface of the field to the hollows of the disk equal to the height of the stubble of the field to be treated, the straw is placed in the gap with the exit to the field surface in the form of a micro-curtain, which helps to retain snow, which reduces the freezing of the soil adjacent to the gap, and the involute profile protrusions eliminates the removal of straw when they exit the gap.
