Abstract

FIELD: agriculture. SUBSTANCE: apparatus has frame with furrow cutting disk mounted for free rotation on horizontal shaft fixed on frame. Furrow cutting disk has working surface with trapezium-shaped section corresponding to predetermined shape and sizes of profiled furrow. Two flanges made in the from of flat ring are arranged in symmetry on furrow cutting disk. Oval or disk-shaped furrow opening member is rigidly mounted on frame or on four-link parallelogram mechanism, in front of furrow cutting disk in the course of advancement of apparatus. Furrow opening member cuts furrow of trapezium-shaped section, which is less than size of furrow to be formed by 20-40 mm. Such construction of apparatus allows slopes, furrow bottoms and adjacent bed edges to be compacted and, as a result, slant or slope soil washing out to be prevented during monsoon and prolonged rains. Apparatus of such construction may be used for forming and restoring of agronomic ameliorating bed furrows in excessive humidity regions. EFFECT: increased efficiency, simplified construction and improved quality of furrows. 2 cl, 2 dwg

Description

 The invention relates to agriculture and agricultural machinery, in particular to tools for the formation and restoration of grooves of irrigation and drainage ridges.

 Known devices in which for the formation of irrigation and drainage ridges are used furrow-opening devices of the dump type and a roller located behind it (SU 1817664 A3, A 01 B 13/00, 05/23/93). Similar devices are used to restore furrows during inter-row cultivation of crops cultivated on ridges. Furrow restoration is caused by the need to combat weed vegetation on the slopes of ridges, in connection with which loosening and destruction of the slopes of ridges occurs, filling of the furrows with loose soil, which during prolonged and monsoon rains leads to erosion of slopes and washout of furrows from 20 to 30 tons of fertile soil . This leads to a decrease in crop yields, siltation of land lying relative to the field, contributes to the deterioration of the environmental situation. This is the main disadvantage of the above furrow-forming devices.

 Closest to the claimed is a device for the formation of profiled grooves containing a frame and mounted on it a furrow-opening element and a furrow-forming disk (SU 1409142 A, A 01 B 13/16, 07/15/08).

 The disadvantage of this device is that it provides a seal only the bottom of the furrow without compaction of its slopes. Thus, when excess water is discharged along the furrows during heavy rains, the soil is washed off due to loose compaction.

 The technical result is the provision of formation and restoration of furrows, reducing erosion of slopes of ridges and soil erosion along furrows during prolonged and monsoon rains. This is achieved by the fact that in a device consisting of a frame with a furrow-opening element installed on it and a furrow-forming disk having a working surface with a trapezoidal cross-sectional shape, on which two flanges in the form of a flat ring are symmetrically mounted. Moreover, the furrow-opening element is made of a dump or disk type, and the size of the furrow formed by the furrow-forming disk is 20 - 40 mm larger than the size of the furrow cut by the furrow-opening element.

 In FIG. 1 shows a view of a device for the formation and restoration of profiled grooves, side view; in FIG. 2 - the same, rear view.

 A device for the formation and restoration of profiled grooves consists of a frame 1 mounted on the horizontal axis 2 of a freely rotating furrow-forming disk 3 with a working surface with a trapezoidal cross-sectional shape corresponding to the required shape and size of the profiled groove. Two flanges 4 made in the form of a flat ring are symmetrically mounted on the furrow-forming disk. In front of the furrow-forming disk 3 on the frame 1, a furrow-forming element 5, made of a dump type or disk type, is rigidly installed.

 A device for the formation and restoration of profiled grooves works as follows.

 In the process of moving the unit, the furrow-opening element 5 of the device, installed at the required depth, raises and moves the soil from the furrow to the web 6 of the formed ridge. The furrow-forming disk 3 with flanges 4 rotates freely under the action of friction-traction forces with the soil. Since the dimensions of the cross section of the working surface of the furrow-forming disk 3 are 20 to 40 mm larger than the dimensions of the cross-section of the profile of the furrow formed by the furrow-opening element 5 of the device, the slopes 7 and the bottom of the furrow 8 are compacted with soil crumbling from the furrow slopes. The ridges 4 of the furrow-forming disk 3 compact the edges of the ridges.

 The use of the present invention improves the quality of crafts and restoration of the furrows and provides compaction of the slopes and the bottom of the furrow, the edges of the ridge. The proposed technical solution can significantly reduce erosion of slopes and soil erosion along the furrows during monsoon and prolonged rains.
