Abstract

The invention relates to agricultural machinery and can be used for the treatment of soils subject to wind erosion. The purpose of the invention is to provide more complete combing of rhizome weed residues. The tool for extracting rhizomatous residues from the soil contains a drive tooth drum 4 mounted behind flat-cutting paws 3. The drum 4 is made in the form of a shaft 5 with brackets 6 in which holders 10 with teeth 11 are movably mounted parallel to the shaft 5. On the shaft 5 rotatably around it is located on the side of the drum 4 is installed drive vibrator 15. Each holder 10 teeth 11 on one side by means of a lever 12 and a spring 13 is attached to the shaft 5, and on the other hand through the lever 14 interacts with a vibrator 15. During rotation of the vibrator 15, the arms 14 of the holders deflect the tooth 11 in a longitudinal vertical plane. When the levers 14 of the holders 10 are removed, the teeth 11 return to their original position. As a result of the sequential action of the vibrator on the holders 10, the teeth periodically oscillate in a vertical plane, which facilitates the separation of rhizome weeds from the soil. 1 hp f-ly. 5 il.

Description

The invention relates to agricultural machinery and can be used for the treatment of soils subject to wind erosion.

The purpose of the invention is a more complete combing of rhizomatous weeds.

Figure 1 shows a tool for extracting rhizomatous residues from the soil, top view; figure 2 - section aa in figure 1; on fig.Z - vibrator, top view; figure 4 - section bB in fig.Z; on fig.Z - section bb In figure 1.

The tool for extracting rhizomatous residues from the soil contains frame 1 on the support wheels 2. On the frame 1 there are mounted flat-cutting feet 3, and behind the legs 3 there is a driving drum 4 with a horizontal axis of rotation. The drum 4 is located perpendicular to the direction of movement of the gun. The drum comprises a shaft 5 with brackets 6 having openings 7. On the brackets 6 there is fixed a casing 8 with openings 9, elongated in the longitudinal vertical plane of the cannon. In the cavity of the casing 8 parallel to the shaft 5 there are mounted holders 10 with teeth 11, spaced in the openings 9. On one side, each holder 10 is connected by a lever 12 and a spring 13 to the shaft 5, on the other end of the holders 10 there are levers 14. Holders U installed in the brackets 6 with the possibility of rotation. On the side of the levers 14 on the shaft 5, next to the drum 4, there is a vibrator 15 which is mounted rotatably with respect to the shaft 5. The vibrator 15 is made in the form of two disks 16 which are interconnected circumferentially with fingers 17. On the fingers 17 there are rollers 18 The levers 14 of the holders H are in engagement with the rollers 18 of the vibrator 15. An asterisk 19 is welded to the vibrator 15, which by means of a chain transmission 20 is connected to the camshaft

21 drive systems. The shaft 5 is connected via a chain drive 22 to a drive shaft 23. The shafts 21 and 23 are connected by a central gear 24.

The tool works as follows.

During the forward movement of the unit, the flat-cutting legs 3 loose the soil and cut the rhizome weeds. The tooth 11 of the drum 4 combing the soil, while they carry out a complex movement: move progressively with the tool, rotate and oscillate by the action of the vibrator 15 due to the spring-loaded installation. The drum 4 is driven from the tractor's PTO (not shown) through the gearbox 24, the shaft 23 and the chain drive 22, and the vibrator 15 drives from the gearbox 24 through the shaft 21 and the chain gear 20 with an asterisk 19. The vibrator 15 rotates around the shaft 5 and its the fingers 17 with the rollers 18 meshed with the levers 14 guide these levers, turning the tooth 11 in the holes 9 of the casing 8, stretching the spring 13. After the lever 14 leaves the roller 18, the tooth 11 returns to its original position . The next roller 18 runs onto the same lever 14 and, stretching the spring 13, drives it. As the teeth 11 vibrate, rhizomatous weeds are more easily separated from the soil. As the drum rotates, the 4 weeds are carried away by the teeth 11 on the soil surface and are shed.

Thus, when tilling the soil with this tool, the soil simultaneously loosens and is removed to the surface of the rhizomes of weeds. Rhizo residues, evenly distributed over the surface of the floor, protect the soil from wind erosion.

Claims (2)

1. A tool for extracting rhizomatous residues from the soil, containing flat cutting attached to the frame paws and a drive tooth drum mounted behind the paws with a horizontal axis of rotation, perpendicular to the direction of movement of the tool, characterized in that, in order to more thoroughly comb out rhizomatous weeds, the tooth braban is made in the form of a shaft with holes in the casing, on which, by means of springs and with the possibility of movement in the longitudinal vertical plane, are mounted the tooth holders, By this, the teeth are placed in the openings of the drum casing, and the drum is provided with a vibrator mounted on its shaft rotatably with respect to the latter, and each tooth holder has a lever for interacting with the vibrator. 2. The tool according to claim 1, characterized in that the vibrator is made in the form of having two disks driven, rigidly interconnected by the last fingers arranged on a circle, on which are mounted located parallel to the shaft, with js rollers.
