Abstract

The invention relates to agriculture, in particular, to soil cultivating hand tools for working on a personal plot. The aim of the invention is to improve the quality of tillage. The tool contains a cutting 20 with a holder 8, on which the knife 1 is fixed by means of racks 7 and brackets 5. Knife 1 is made in the form of a plate with cutting edges 2 along the perimeter bent in the longitudinal plane passing through the axis of symmetry. At the intersection of the edges 2, teeth 3 are installed. The distance between adjacent teeth 3 is greater than the width of the plate. The knife 1 is installed on the holder 8 with the ability to adjust the angle of installation and fixation, adjust the height and angle. The cutting 20 in the lower part is hollow and connected to the holder 8 by means of a spring 14 located in their cavities. Between the pipe 12 the cutting 20 and the pipe 13 of the holder 8, a shock absorber 19 is installed. By installing the knife 1 at different angles to the holder 8 with the cutting 20 various work options - weeding, mixing different materials, grinding weeds and root crops, forming holes, hilling plants. 3 hp f-ly, 1 ill.

(57) The invention relates to agriculture, in particular, to soil-cultivating hand tools for working on a personal plot. The aim of the invention is to improve the quality of tillage. The tool contains a cutting 20 with a holder 8, on which a knife 1 is fixed by means of racks 7 and brackets 5. The knife 1 is made in the form of a curved longitudinal

a plane passing through the axis of symmetry; plates with cutting edges 2 along the perimeter. At the intersection of the edges 2, teeth 3 are installed. The distance between adjacent teeth 3 is greater than the width of the plate. The knife 1 is installed on the holder 8 with the ability to adjust the angle of installation and fixation, adjust the height and angle. The cutting 20 in the lower part is hollow and connected to the holder 8 by means of a spring 14 located in their cavities. Between the pipe 12 the cutting 20 and the pipe 13 of the holder 8, a shock absorber 19 is installed. By installing the knife 1 at different angles to the holder 8 with the cutting 20 various work options - weeding, mixing different materials, grinding weeds and root crops, forming holes, hilling plants. 3 h. item f-ly, 1 ill.
