Description

DESCRIPTION OF A USEFUL MODEL. ROTARY TILLING HOUSING

The utility model relates to seedlings (household engineering, namely tillage tools for pre-sowing soil preparation.

The purpose of the development of this field model is to create a new wide-spread rotary tillage implement that meets the requirements of moisture-saving soil cultivation technology while reducing the metal consumption and labor input of working bodies and improving the layout scheme to increase stability in the longitudinal-vertical plane while maintaining the maneuverability of the unit.

Cast wedge-shaped working bodies of agricultural machinery are widely known, which crush blocks, clods and firmly compact the soil, for example: copyright certificate (I) No. 114944 AB 29/04 of 1983.

Rotary tillage implements with discs are also known, each of which is equipped with knives fixed at its edge and located at an angle to the plane of the disc (2); author certificate No. 1535395 A1 А01В 21/04 of 04.19.88.

The disadvantage of cast-iron working bodies is that they do not provide crushing of blocks and lumps in the row-spacings, which reduces the quality of pre-sowing preparation of the soil, as well as the fragility (insufficient strength) of spurs, snits and rim discs with relative complexity and high manufacturing cost.

Electric-welded disks with knives fixed along their perimeter and located at an angle will provide high quality soil cultivation, but they are also difficult to manufacture, since they require mechanical processing, assembly and electric welding of each knife body mounted on the working disk.

These drawbacks are deprived of the working body proposed for use in this utility model according to the patent (3) J 2099908 according to the application No.% 101226/13 of 16.01.96, which are bent at an angle to the plane of rotation of the spur disc which

obtained by simple stamping (by the method of overload followed by folding). In addition, the disadvantage of the known ring-spur rollers is sticking of the die on wet soils and jamming of the shafts, which leads to rapid wear of the disc hubs. The working body according to patent 3 2099908 according to the application JVfe 96101226/13 of 01.16.96 is not subject to sticking due to features of the geometry of the periphery of the disks and can work at elevated speeds on pfeuvlazhennyh soils.

When working in an arid zone using moisture-saving technology, the proposed working body provides the necessary and sufficient depth of the upper mulching layer, and a dense layer is located at the depth of seed sowing and is not destroyed during sowing.

The layout schemes of high-capture agricultural machinery, consisting of separate sections, are quite known, for example: (4) copyright certificate No. 1033021 A AO 1B 21 / Q4 of 08.09.80.

The closest to the proposed rotational tillage implement according to the layout scheme is the tillage implement (5) copyright certificate No. 898966 AO 1V 29L) 4 dated 04/28/80, including a tow hitch, a frame on which two rows of discs are mounted on parallel horizontal axes, equipped with two rows of discs are awesome & w discs that are installed in front of the main ones.

The forward disks provide the stability of the main disks in the longitudinal vertical plane, which leads to improved soil cultivation.

However, this tillage implement is not wide-spread, it does not copy the relief of the surface to be treated, and its tow hitch is not universal. The purpose of the proposed utility model is to eliminate these drawbacks.

This goal is achieved by the fact that the rotary tillage implement containing a frame consisting of sections articulated: special sections on each of which ring-spur working bodies according to patent No. 2099908 are mounted on parallel horizontal axes, is equipped with additional, paired forward discs located in the interschion space. Moreover, the combined trailer

- The arrangement of the rotary tillage implement contains elements for connecting to the tractor and the heavy harrow frame, and the additional forward mounted twin discs have elements for grabbing to the trailer grip and articulated sections of the implement frame.

A rotary tillage implement works as follows: with the help of a combined trailing device, the implement is attached to a tractor or a frame of a heavy dshskoy harrow. When the harrow moves forward, its discs loosen the soil to a depth of 120 mm. Traces of heavy harrows remain in the form of furrows of different widths and depths and plant debris. The annular-spur working body of a rotary tillage implement is penetrated into the soil with spurs, and the oshory vertex cuts into a lump, and, with further movement, splits it under the influence of its mass and the mass of the implement as a whole, and then splits the soil with spurs and spheres of discs with protrusions small and compacts the soil in the wake of movement and forms a mulching layer.

The installation of double-disc sections in the intersection space of a rotary tillage implement allows you to ensure the same distance between the tracks of the discs across the width of the capture of the implement, which determines the tillage without blemishes.

A comparative analysis with the prototype and other known devices shows that pshorovy working bodies, articulated sectional connections, forward disks, towing devices are widely known, however, their introduction in the indicated new connections with the remaining elements of the scheme in the proposed rotary tillage implement leads to an improvement in the quality of soil cultivation with a simultaneous increase in the width of the capture of the gun - to reduce the intensity and laboriousness of the manufacture of workers (fganov, meets the requirements of moisture This allows us to conclude that the technical solution of the Epheterium is “novelty,“ significant differences and “industrial applicability.
