Abstract

The invention relates to agricultural machinery, in particular to tillage working bodies. The purpose of the invention is to improve the quality of soil cultivation, reduce traction resistance and destroy weeds in the protective zone of the row. The rotary working body consists of a rack 1 and a disk 4 with knives b, while the disk 4 is freely mounted on an inclined axis 3, mounted on the lower end of the rack 1. On each knife 6 mounted soiltrainer 11 and soil-shifting plate, while the knife 6 is installed with an angle cutting relative to the plane of rotation of the disk 4 equal to 10 °; , and its cutting edge is made along a hyperbole. The spreaders 11 are arranged in a circle with a radius of 1, where r is the radius of the disk 4, R is the radius of the circle along which the free ends of the knives 6 are located. During operation, the spreaders 11 provide reliable engagement of the working body with the soil, ensuring its rotation without slipping. Knives 6 loosen the soil between rows and cut weeds with minimal resistance. 6 ill. sl c

FIELD OF THE INVENTION The invention relates to agricultural machinery, primarily to aggregates for processing interstitial.

The purpose of the invention is to improve the quality of soil cultivation and the destruction of weeds in the protective zone of the row.

Figure 1 shows the rotary working body of the cultivator, rear view; figure 2 is the same side view; Fig. 3 is a ring for fixing knives in a perspective view; figure 4 - rotary working body of the cultivator, top view; figure 5 is a section aa in figure 4; figure 6 is a knife in a perspective view.

The rotary working body consists of a rack 1, mounted on a cultivator rod 2, and an axis 3. on which a flat disk 4 is mounted. A ring 5 is mounted under the disk 4. Knives 6 are evenly fixed around the periphery of the disk 4 and ring 5 by means of a bolt joint 7. For fixing the position of the knives, the ring 5 is provided with grooves 8. On the free end of each knife 6, holes are made for fastening the soil-shifting plate 9 with screws 10. On each knife b mounted couplings 11. The cutting edge of each of the knives 6. installed with a re-angle Ani relative rotation of the disc 4 plane in the range 10 ° 20 °, is formed by a hyperbola. In this case, the radius of the circle along which the spreaders 11 located on the knives 6 are located is in the range 1, where r is the radius of the disk 4, R is the radius of the circle along which the free ends of the knives 6 are located.

The rotary working body of the cultivator operates as follows.

On the field, the unit is installed so that each rotary working body is located between rows of crops with a shift from the middle of the rows to the side of the row of plants obliquely at an angle of 15-25 ° in the transverse vertical plane and at an angle of / 10-20 ° longitudinally vertical plane. When the unit moves, the rotary working body attached to the rack 1 by means of the lock 2, due to the interaction of the mounted on the knives 6 in the range 1, the soil 11c rotates the soil on the axis 3.

The knives 6, pressed from below to the disk 4 by means of a ring 5 having grooves 8, and bolts 7, rotate together with the tipping arms 11. At the same time, the cutting edge of each of the knives b,

established with a cutting angle of 10 ° at 20 ° and executed on a hyperbole, it is embedded in the soil with low resistance and cuts the weeds without clogging the working body.

Soil-shifting plates 9, fixed to the knives 6- by means of screws 10, displace the soil from the plants towards the middle of the middle row, aligning the groove profile. To prevent young plants from falling asleep, plates 9 are mounted with CMS spacing from the free end of knife 6 to a distance of 7-10 mm.

For processing one row, two rotary working bodies are used in combination with other working bodies,

required by the agrotechnical requirements for this type of processing. To prevent damage to the plants, guard shields 12 are mounted on the cultivator section.

The use of a new rotary working body provides an increase in the degree of mechanization of soil cultivation between rows due to loosening of the soil and destruction of weeds in the protective soil.

Claims (1)

The claims of the Rotary working body of the cultivator, including mounted on an inclined axis of rotation of the disk with evenly knives fixed around its circumference and tillers mounted around a circle on the lower surface of each of the knives mounted with a cutting angle relative to the plane of rotation of the disk, characterized in that, in order to improve the quality of cultivation of the soil, reduce traction resistance and destroy weeds in the protective zone of the row, the cutting edge of each of the knives is made on a hyperbole set with a cutting angle relative to the plane of rotation of the disk in the range of 10, while the radius of the circle on which the spreaders are located is in the range 1, where r is the radius of the disk; R is the radius of the circle along which the free ends of the knives are located.
