Description

The utility model relates to the field of agricultural engineering, in particular to tillage cutters with a vertical axis of rotation.

A milling cutter for tillage is known [Copyright certificate RU patent No. 187454, IPC class. A01B 33/06, 61/04, 2019], in which the safety mechanism is simple to manufacture. The disadvantage of the technical solution is the lack of rotation (and therefore oscillation) relative to the vertical axis passing through the knife stand, which leads to a decrease in the quality of tillage and practically does not reduce energy costs for tillage.

The closest analogue to the claimed one is the rotor of a tillage cutter with a vertical axis of rotation [Copyright certificate RU patent No. 208672, IPC class. A01B 33/06, 2021], containing a vertically located elastic spring, fastened with the possibility of simultaneous compression, stretching and twisting, the upper end with an upper cup welded to the rotor holder and a guide bushing welded to the cup, and the lower end through the lower cup and welded to it sleeve - with a stand attached with a countersunk screw.

The disadvantage of this design is the high energy intensity of operation. Some effect of reducing energy intensity is achieved only due to vibration of the working body along the vertical axis and around it, and self-installation in the direction of least soil resistance in the horizontal plane, which significantly reduces energy intensity, is not available. The circular cross-section of the part of the working body strut moving in the soil also increases energy intensity.

The technical result of the utility model is to reduce the energy intensity of the work.

The technical result is achieved due to the fact that a triangular section post with a sharpening angle of the front edge of 50°, having a landing plane with two holes at the lower end, is vertically attached to the intermediate post through a horizontal driver by means of bushings and countersunk screws. for attaching the working element.

This set of essential features ensures that the inventive rotor of a tillage cutter with a vertical axis of rotation has new properties that differ from the prototype.

Thus, the declared features of the utility model meet the “novelty” criterion.

In fig. Figure 1 shows a diagram of a rotor of a tillage cutter with a vertical axis of rotation, front view;

in fig. 2 - the same, side view.

The rotor of a tillage cutter with a vertical axis of rotation, containing a vertically located elastic spring 9, fastened with the possibility of simultaneous compression, stretching and twisting, the upper end with an upper cup 11 welded to the rotor holder 12 and a guide sleeve 10 welded to the cup, and the lower end through a freely inserted into the guide bushing 10, the guide rod 13, the lower cup 8 and the bushing 7 welded to it - with an intermediate post attached with a countersunk screw 14, and to the intermediate post 15 through a horizontal guide 4 by means of bushings 6, 17 and countersunk screws 5, 16 vertically attached, offset to the side opposite to the direction of movement, is a post 18 of triangular cross-section with a sharpening angle of the front edge of 50°, having at the lower end a landing plane 2 with two holes 1, 3 for attaching the working element.

The rotor of a tillage cutter with a vertical axis of rotation operates as follows.

Before work, the working element is attached to the landing plane 2 using holes 1, 3 with a threaded connection.

During operation, the rotor holders 12 rotate around a drive shaft not shown in the figures. In this case, the working bodies of the rotor and the lower part of their racks 18 of triangular cross-section move in the soil along a trachoid-shaped trajectory relative to fixed Cartesian coordinates, and effectively loosen the soil and trim weeds.

The sharpening angle of the front edge of the racks at 50° allows the rack, according to [Klenin P.I., Sakun V.A. Agricultural and reclamation machines - M.: Kolos, 1994. - P. 40], cut the soil without forming and holding a dense soil core in front of the cutting part, which reduces the energy intensity of the work.

At the same time, the displacement of the rack 18 relative to the intermediate rack 15 back, against the direction of movement and its connection through the transition links with the spring 9, allows the rack 18 and the working body attached to it to self-align in the direction of movement and make angular oscillations in the horizontal plane, oriented in the direction of least resistance soil, which also reduces the energy intensity of the work.
