Description

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

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

The disadvantages of the described working body include: it requires agrotechnical time after the previous operation - cultivation, to envy cropped root shoot weeds, so as not to take root after rolling, and to adjust the pressure on the soil, an additional load is required.

The closest device to the claimed object according to the set of essential features is a battery of multi-operational rollers, the working bodies of which are ring-shaped, connected by means of spokes to the axis of the battery mounted at an angle to the direction of movement of the unit. The ring of the roller is in the form of a cylinder, on the edges of which opposite sharpening angles are made. The spokes form an eccentric joint of the ring with the axis. The rollers are made up of a battery with a multiple pitch eccentricity around the circumference. Batteries with leashes connected to the frame of the gun. For the steady movement of the battery, a jet link is installed between the leash and the frame. 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 surface of the field, comb the previously trimmed weeds (decision to grant a patent for application No. 2005104886/11 of 02.22.2005 )

The prototype and the claimed invention has the following significant similar features: the working bodies of the rollers are made in the form of cylindrical rings; the rings are connected by means of spokes to the axis of the battery; roller batteries are installed at an angle to the direction of movement of the unit; between the leash of the 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 insufficient rolling of the soil and uniform progress in depth, soil sticking to the inside of the rim of the roller and, as a result, increased traction resistance of the implement, the complexity of manufacturing the roller.

The invention consists in the following.

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

The technical result is an increase in the quality of rolling and mulching the soil, reducing the adhesion of the soil to the rim.

The specified technical result during 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 is installed at an angle to the direction of movement of the unit, reactive traction is installed between the rollers and the gun frame, the ring rollers are made in the form of a cylinder, opposite the corners of which are sharpened and have perforations in the form of holes along the perimeter of the rim.

Due to the fact that the ring rollers in the form of a cylinder with sharpening of opposite angles at the edges have perforations in the form of holes along the perimeter of the rim, the aforementioned 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 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.

The invention is illustrated by drawings:

Figure 1. Tillage tool “Perforating roller”.

Figure 2. Working body perforating roller.

Figure 3. Battery rollers (top view).

Figure 4. Skating rink in the "active" and "passive" modes.

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

Tillage tool "Perforation roller" (see figure 1) contains a frame 1, a towing device 2 (or attachment), support wheels 3, battery rollers 4, a push device 5, leashes 6, jet thrust 7.

The roller roller through the bearing assemblies is attached to the leads 6 and through them to the unit frame 1. The pressure device 5 is connected at one end to the carrier 6, and the other movably, through adjustable compression springs, with the connecting beam of the frame 1.

The rollers of the batteries are made in the form of rings with a diameter in the limit of 500 mm (see figure 2), having the shape of a cylinder. The edges of the rim of the ring have a sharpening with opposite angles. The width of the ring rim is 60 ... 80 mm, the thickness of the ring is 6-10 mm. The ring rollers have perforations in the form of holes with a diameter of 30-40 mm around the perimeter of the rim and are connected by means of spokes to the inner sleeve. The rollers are assembled into a battery, the distance between the rollers is 80 ... 120 mm.

The batteries of multi-stage rollers are connected to the frame using leashes and can be installed with a change in angle of attack of 0 ... 25 °.

The pressure rods are designed to set the depth of the multioperation rollers, 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 batteries of perforating rollers are justified from the condition of ensuring high-quality cutting and combing of weeds, crumbling, leveling and compaction of the soil. At the same time, the immersion depth of the rollers should be 4 ... 6 cm, when setting the zero angle of attack - 2 ... 4 cm.

The movement of the points of the rim of the rollers in the soil occurs along a complex path in the form of a cycloid (helix) and 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 holes along the perimeter of the rim leads to the forcing of the soil through them during movement, thereby cleaning the inner surface of the rim from the soil. The use of the proposed rollers at a zero angle of attack (surface rolling of the soil) allows for intra-soil rolling, leaving a loosened soil layer on the treated surface due to the passage of soil through holes along the perimeter of the rim, which additionally ensures the conservation of soil moisture in the arid zone.

Figure 3 shows the battery rollers, top view. To ensure the high-quality operation of the rollers in various soil conditions, its design provides for two installation options: “active” and “passive”.

Variants of the "passive" mode of installation of multi-operational rollers (see Fig. 4) are used for working on soft soils and pre-sowing treatment, providing the necessary deepening of them 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.

When working on solid soils and when chamfering on stubble, the rollers are set to “active” mode by moving the batteries, turning them 180 ° so that the sharp peaks of the inner sharpening of the 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 inability to deepen the 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.

Multioperational perforating rollers can be used both as independent working bodies of the implement and as constituent elements 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.
