Description

The inventive utility model relates to the field of agricultural engineering, and in particular to the working bodies of cultivators designed to care for potato plants.

Known cultivator okuchnik KON-2,8A, containing a frame with an attachment device to the tractor and working sections, based on the copy wheels. To destroy weeds, the cultivator is equipped with a set of rotary working bodies, including conical rotary cultivators (Intensive technology for the production of potatoes): Collection. - M.: Moscow Worker, 1987.p. 91-96. Scientific and technological progress in the agricultural sector.

Also known is a rotary cultivator containing two conical rotary harrows attached to the hubs with the possibility of free rotation around a horizontal axis (patent for invention No. 2388199, class AB01/00).

The disadvantages of the rotary cultivator according to patent No. 2388199, class. A01B 21/00 for the destruction of weeds and loosening of the soil are the limited regulation limits of the rotary harrows for the angle of inclination of the ridge side and the high metal consumption of the structure.

The purpose of the invention is to increase the efficiency of weed control and loosening of the soil due to the accuracy of the adjustment of the rotary harrows at the angle of inclination of the ridge sides, as well as to reduce the metal consumption of the rotary cultivator.

This goal is achieved by the fact that for processing the crest surface of a different profile of the crest, the rotary cultivator is equipped with two rotary harrows with loosening teeth attached to the hubs with the possibility of free rotation around the axis mounted on the suspension. The suspension includes a rack and a crankshaft bent at both ends. The stand is freely mounted on the crankshaft axis and is fixed to the disk welded to the crankshaft axis using a bolt and a lock nut.

The invention is illustrated by drawings: In FIG. 1 shows a rotary cultivator; in FIG. 2 - suspension; in FIG. 3 - crankshaft suspension axis.

The rotary cultivator consists of a suspension composed of a rack 1, a disk 2 and a crankshaft axis 3, two rotary harrows 4 mounted to the hubs 5.

The crankshaft axis is made by notches 6 of the axis 2 (FIG. 2) in two places at half its diameter, followed by a bend of 15 ° and welding the notch by manual arc welding (FIG. 3).

The suspension strut is installed with the possibility of circular rotation around the crankshaft axis, followed by fixing by means of a bolt and a lock nut through the holes on the strut and disk by manual arc welding to the crankshaft.

The rotary cultivator is installed resistant 1 to the working section of the cultivator (not shown).

The technological process performed by the rotary cultivator is as follows. In the work, rotary harrows, rolling along the surface of the ridge, loosen the soil, comb out the weeds, breaking the connection of the root neck of the weeds with the soil.

The rotary cultivator simultaneously performs the function of a supporting-copy wheel of the cultivator working section.

To adjust the rotary harrows 4 to the angle of the ridge sidewall, remove the bolt 7 fixing the rack 1 with the disk 2 welded to the crankshaft 6 and rotate the crankshaft with the rotary harrows relative to the rack 1 by an angle corresponding to the angle of inclination of the ridge side.

Thanks to this design of the rotary cultivator, the accuracy of adjusting the rotary harrows to the angle of inclination of the ridge side increases and the efficiency of weed destruction and loosening of the soil is increased, and also due to the design of the suspension, the metal consumption of the rotary cultivator is reduced.
