Description

The invention relates to agricultural machinery, in particular to tillage working bodies, and can be used for loosening the soil, rolling it, cutting and combing weeds, leveling the treated surface.

Known ring-spur skating rink type ZKKSh-6, made of a set of discs mounted on an axis, which have zigzag fingers in order to improve the quality of soil cultivation along the rim (Agricultural Equipment catalog, volume 1, part 1, M., 1991, p. 170).

The disadvantages of the described working body include:

the need for agricultural time after the previous operation (cultivation) for wilting of pruned root weeds;

An additional load is required to adjust the pressure on the soil.

The closest device to the claimed facility for the combination of essential features is a battery of multioperational cone rollers-levelers for tillage. The working bodies of the rollers are made in the form of rings having the shape of a truncated cone. The conical rings are connected by means of spokes to the axis of the battery. Batteries with leashes connected to the frame of the gun. For steady movement of the battery between the leash and the frame installed jet traction. The batteries of the cone rollers are installed at an angle to the direction of movement and during operation they move the soil layer forward and in the transverse direction, break up the soil lumps, level and compact the field surface, comb the weeds previously cut by other working bodies (Recommendations for the use of combined Leader tillage machines in resource-saving agricultural cultivation technologies. - Krasnoobsk village, Revik-K LLC, 2002, p. 34).

The prototype and the claimed invention have the following similar essential features:

the working bodies of the rollers are made in the form of rings having the shape of a truncated cone;

conical rings are connected by means of spokes to the axis of the battery;

batteries of cone rollers are installed at an angle to the direction of movement of the unit;

between the leash of the cone rollers and the frame of the gun installed jet traction.

The reasons that impede the achievement of the required technical result when using the known device include the lack of cutting of weeds, poor quality of crumbling soil, insufficient rolling of plant residues, increased traction resistance of the implement.

The invention consists in the following.

The problem to which the invention is directed is to increase the functionality and quality of the rollers, as well as reducing the traction resistance of the gun.

The technical result - cutting weeds, improving the quality of continuous loosening and mulching of the soil, reducing traction resistance of the gun.

The specified technical result in the implementation of the invention is achieved by the fact that the battery of rollers having the shape of rings connected by means of spokes to the axis of the battery mounted at an angle to the direction of movement of the unit. A jet thrust is installed between the lead of the cone rollers and the implement frame, in addition, the rings along the rim of the rollers are made with one-sided corrugation, one end of the reactive draft has a damper connection, and one of the leads of the battery is made of a sliding structure having a sliding part and a push lever, the sliding part is located from the side opposite the axes of attachment with the frame.

Due to the fact that the ring rollers on the rim are made with one-sided corrugation, and have a sharpening along the rim edge, one of the sides of the jet thrust has a damper connection, and one of the battery leads is made of a sliding structure having a sliding part and a pressure lever, the sliding part is located with side opposite to the axes of attachment with the frame, and the above technical result is achieved.

The analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allowed to establish that the applicant did not find an analogue characterized by features identical to all the essential features of the claimed invention.

Therefore, the claimed invention meets the requirement of "novelty" under applicable law.

To verify the compliance of the claimed invention with the requirement of "inventive step", the applicant conducted an additional search for known solutions in order to identify features that match the distinctive features of the prototype of the claimed invention. The results show that the claimed invention with the identified essential features does not follow for the specialist explicitly from the prior art.

Therefore, the claimed invention meets the requirement of "inventive step" under applicable law.

Information confirming the possibility of carrying out the invention are as follows.

Tillage tool "Multi-purpose roller" made trailed and contains a frame 1 (see figure 1), a towing device 2, support wheels 3, batteries conical corrugated rollers 4, pressure device 5, leashes 6, jet thrust 7.

The battery of cone rollers 4 consists of a middle section, to which the bearing units 8 and two extreme sections are attached. The battery through the bearing assemblies 8 (see figure 2), inserted into the eyes 9 of the leads 6 and fixed in them by the fingers 10, are connected to the leads 6 and through them to the frame of the unit 1. The pressure device (see figure 3) at one end 11 is connected to the lead 6, another movably through the sleeve 12 - with the connecting beam of the frame 1. On the body of the rod 13 on different sides of the sleeve 12 there are compression springs 14 fixed by the washer 15 and the adjusting nut 16.

Jet thrust 7 in design (see figure 4) is similar to the push device 5, one end connected to a leash 6, and the other through a damper device with frame 1.

The rollers 17 of the batteries are made in the form of rings with a diameter of 500 mm, having the shape of a truncated cone (see Fig.7). The rink rings along the rim are made with one-sided corrugation. The width of the ring rim is 30 ... 40 mm. Tapered rings are connected by means of spokes to the axis of the battery, with a distance of 110 mm between them and 130 mm in the area of the bearing units.

The batteries of the multioperational cone roller can be installed with a change in the angle of attack of 0 ... 25 ° (see figure 5).

The battery 4 is connected to the frame using leashes 6, one of which has a constant length and is additionally connected through a jet rod to the frame, and the other can change the length (for example, has the design of a telescopic tube), thereby adjusting the angle of attack of the battery. The constructive decision that the retractable part of the leash is on the side opposite to the axes of attachment with the frame is explained by the exception of changing the geometric parameters of the attachment of the pressure rod when changing the setting of the angle of attack of the battery.

The pressure rods are designed to set the depth of the multioperational roller, adjust the necessary pressure of the working bodies on the soil depending on its density by changing the force of the installed springs, and also adjust the height of each end of the battery.

The parameters of the multioperational roller batteries are justified from the condition of ensuring high-quality cutting and combing of weeds, crumbling, leveling and soil compaction. At the same time, the immersion depth of the rollers should be equal to 4 ... 6 cm.

The movement of the rim points of the rollers in the soil occurs along a complex path in the form of a cycloid (helix), which has a significant effect on cutting weeds, most of which are combed to the surface by the lateral edges of the rings and die. The overlap area of the cutting line by each roller depends on the depth of cultivation and the angle of attack of the battery.

The presence of corrugation along the rim of the rink, rolling in the working zone of soil movement, forms an oscillatory movement, regulated by a jet throttle damper. The shape of the corrugation cone with its curves improves the quality of the zigzag compaction, crumbling and leveling of the soil surface. Oscillations of the battery from rolling the corrugations of the disk occur simultaneously in two planes, which reduce the traction of the base tractor and improve the quality of soil cultivation.

To ensure the high-quality operation of the rollers in various soil conditions, its design provides two options for their installation: “active” and “passive”.

A variant of the "passive" mode of installation of a multi-stage roller (see Fig. 6) is used for working on soft soils and pre-sowing treatment, provides the necessary deepening of it into the soil, cutting weeds, compaction of the layer with the creation of a mulched leveled loose layer with a depth of 4 ... 6 cm above it with effective combing of weeds. In this case, the sharp tops of the conical rims of the rollers are directed to the longitudinal axial line of the unit.

When working on solid soils and when chamfering on stubble, the rollers are set to the “active” mode of operation by moving the batteries, turning them 180 ° so that the sharp tops of the conical corrugated rim of the rollers are directed to the longitudinal center line of the unit.

In some cases, when treating heavy soils with high humidity, because of the impossibility of deepening the cone rollers by more than 2 ... 3 cm, a situation arises when the quality of processing sharply decreases, i.e. the surface is poorly leveled, weeds are not combed out completely, lumps of soil are not destroyed. In this case, it is recommended to pre-cultivate the soil with lancet paws.

The multi-stage roller can be used both as an independent working body of the gun and as a component in combined units.

Thus, the above information indicates that when using the invention the following set of conditions:

means embodying the invention in its implementation, is intended for use in agricultural machinery;

for the invention in the form described in the independent claim, the possibility of its implementation using the means and methods described above or known prior to the priority date is confirmed;

the means embodying the invention in its implementation is capable of achieving the achievement of the technical result perceived by the applicant.

Therefore, the claimed invention meets the requirement of "industrial applicability" under applicable law.
