Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce weed infestation by increasing the degree of extraction of weed rhizomes. The device comprises a frame on which a flat-cutting paw having a perforated surface is hinged. A flat cutting paw is made in the form of two-sided wedges symmetrically placed on both sides of the stand. On horizontal axes, rotors 3 are installed, made in the form of knives-extractors, including racks with teeth fixed on them, and rotors 5, teeth-combers of which are made in the form of rods with plates of variable length fixed on it. When performing a technological process, the cutting paw cuts a layer of soil at a certain depth and loosens it. The rotors 3 and 5 remove and comb out the rhizomes of weeds from the cut soil layer. 3 hp f-ly, 6 ill.

FIELD OF THE INVENTION The invention relates to agricultural machinery.

The purpose of the invention is to reduce weed infestation by increasing the degree of extraction of weed rhizomes.

FIG. Figure 1 shows a tool for extracting rhizishchornok from the soil, side view; figure 2 - the same in terms of; on fig.Z - a knife-extractor in the plan and on the side: on figure 4 - a flat-cutting paw; figure 5 shows a tooth comb in the plan; figure 6 - shows the interaction of the working bodies in the plan.

A tool for extracting rhizomes of weeds from soil consists of a supporting frame 1, oscillating (vibrating) flat-cutting legs 2 attached to it, removing the rotor 3, removing rotors 5, discharging rotor 5 into the hopper 4, reflector 6, leveler with pressure device 7, cylinder 8 , gearbox 9 drive with transmission shaft 10, safety couplings 11, cam mechanism 12 paw vibrator, stabilizer 13 oscillations (vibrations) of spring paws, hitch 14, rotor drive 15, support wheels 16 and leveler 17.

The flat cutting paw is provided with lateral flat cutting edges 18 and has a perforated surface for separating the loosened soil.

The weed rhizome extractor knife consists of a stand 19, on which the carbon teeth 20 are fixed at some angle to it, and the tooth combders are made in the form of rods 21 with variable length plates 22 fixed on them.

The working bodies are driven from the tractor's power take-off shaft.

A tool for removing rhizomes of weeds from the soil works as follows.

When moving along the field to be processed, flat-cutting paws 2 evenly distributed across the width of the guns, performing simultaneously reciprocating (oscillatory) movement using the cam mechanism 12, cut the soil layer to the depth of the weeds rhizomes, lift it, loosen, separate, rhizome section. from the bulk. At the same time, the flat side cutting edges 18 of the paw 2 ensure the stability of the course over the depth of the rhizomes of weeds and the stability of the cutting of the soil layer, and the oscillatory movement of the paw with a symmetrical outline and a perforated surface makes it possible to loosen and fluff the soil, partially separating it and separating rhizome. The rotor 3, located between

the legs of the paws 2, rotating in the working area in the direction opposite to the movement of the gun, with the help of the gear 9 and the drive 15, the teeth 20 pick up the rhizomes in the loosened soil layer and lift them up where they fall under the teeth of the rotor 5, having the opposite rotation from the rotor 3, and thrown into the bunker 4. In doing so, lumps

Soils with rhizomes of weeds, accidentally falling under the tooth-combers, hitting the reflector 6, are separated. At the same time, the soil falls to the floor surface and the rhizomes fall into the bunker. WITH

With the help of the pressure device 7, the leveling device 17 levels the floor surface with residues of soil scattered from rhizomes, which prevents the formation of ridges.

Emerging on the path of flatheads

The paws random short-term loads are stabilized with 13 vibrations, and at the roto (x 3, removing weeds rhizomes, with safety clutches 11.

Cut depth required

soil in the process of work is established by the support wheels 16.
