Abstract

FIELD: agriculture.

SUBSTANCE: rotor comprises a frame on which the support wheel and the working section are mounted. The working section is made driven by the power take-off shaft (PTO) of the tractor through the gimbal gear, an intermediate support, a gimbal gear and a parallel-shaft reduction gear unit. On the frame of the rotor on the track of the tractor wheels, at a depth exceeding the depth of ploughing, the soil rippers are mounted in the form of tow hooks with sharp interchangeable tips. Under the base of the parallel-shaft reduction gear unit a support sheet is mounted, in the form of a skid.

EFFECT: prevention of failure of the working section of the rotor at overloads and pileup of soil under the base of the gearbox, reducing the resistance for movement of the rotor while simultaneous loosening soil compacted by tractor wheels.

Description

The invention relates to agricultural machinery, in particular to mounted tillage rotors, and can be used for basic tillage.

Known rotary plow MVP - 2.4A.00.00.00 (see drawing MVP-2.4A.00.00.00 of the Far MESH, Blagoveshchensk), containing a frame on which a support wheel is mounted, a rotor driven from a power take-off shaft (PTO) tractor through cardan gear, bevel gear, cardan gear and spur gear.

The main disadvantage of the rotary plow MVP-2,4A.00.00.00 is that during its operation the tractor compacts the soil with wheels at a depth exceeding the depth of plowing, thereby violating the water-air regime of the soil.

In addition, on this rotary plow there is no safety device that excludes breakage of the rotor or gears during overloads.

The mounted rotor tillage mounted RPN-1,3 is also known (see RPN passport 00.00.000 PS; Rotor tillage RPN-1,3 OJSC Dalselmash GSKB for machines for the Far East zone, Birobidzhan, 1997), containing a frame on which a support wheel, a stabilizer, a working section driven by a tractor power take-off shaft (PTO) are mounted through a cardan gear, an intermediate support, a cardan gear and a cylindrical gearbox.

The main disadvantage of the rotor of the soil cultivating mounted RPN-1,3 is that during its operation the tractor compacts the soil with wheels at a depth exceeding the depth of plowing, thereby violating the water-air regime of the soil.

In addition, during the operation of the rotor, the base of the cylindrical gearbox touches the ground and unloads the soil in front of itself.

The purpose of the invention:

1. To loosen the soil, compacted by the tractor wheels, at a depth exceeding the depth of plowing.

2. To prevent soil unloading with the base of a cylindrical gearbox and reduce the resistance to rotor movement.

3. To prevent breakage of the rotor working section during overloads, at the same time, perform the safety clutch and the intermediate support with one unit.

This goal is achieved by the fact that on the rotor frame along the track of the tractor wheel, to a depth exceeding the depth of plowing, soil cultivators in the form of canines with sharp interchangeable tips are installed, while a support sheet in the form of a ski is installed under the base of the cylindrical gearbox.

Slots are made on the drive shaft of the intermediate support from the side of the cylindrical gearbox next to the axle, on which the drive disks of the safety clutch are mounted, and the flange of the safety clutch is mounted on the axle with the possibility of rotation, to which the fork of the cardan transmission of the helical gear is attached. The angle of attack of the working section is equal to 20 °.

Thus, the claimed rotary tillage mounted meets the criterion of "Novelty."

Signs that distinguish the claimed technical solution from the prototype, in other technical solutions in this area are not identified, which allows us to conclude that the claimed rotary tillage mounted meets the criterion of "significant differences".

In FIG. 1 shows a rotary tillage mounted, top view; in FIG. 2 is a view A of FIG. one; in FIG. 3 is a section BB of FIG. one; in FIG. 4 - drive shaft of the intermediate support, general view, in a perspective view.

The rotary tillage mounted (Fig. 1) contains a frame 1 on which the support wheel 2 is mounted, the working section 3, driven from the power take-off shaft 4 (PTO) of the tractor 5 through a cardan gear 6, an intermediate support 7, a cardan gear 8 and a helical gear 9 (Fig. 2).

On the frame 1 of the rotor (Fig. 2) along the track of the wheel 10 of the tractor 5, to a depth of "H" exceeding the depth of plowing "h", soil cultivators 11 in the form of canines with sharp replaceable tips 12 are installed, while under the base of the helical gear 9 support sheet 13 in the form of a ski.

On the drive shaft 14 of the intermediate support 7 (Fig. 3) from the side of the cylindrical gear 9 near the pin 15 (Fig. 4), slots 16 are made on which the drive disks 17 of the safety clutch 18 are installed (Fig. 3), and on the pin 15, with the possibility of rotation, a flange 19 of the safety clutch 18 is installed, to which the fork 20 of the cardan gear 8 of the cylindrical gearbox 9 is attached (Fig. 1). The angle of attack "a" of the working section 3 is made equal to 20 °.

Before starting the work of the rotor of the tillage mounted, the plowing depth is set to “h” (Fig. 2) using the support wheel 2, mounted on the frame 1.

When rotating the power take-off shaft 4 (PTO) of the tractor 5 (Fig. 1), the working section 3 is driven into rotation through the cardan gear 6, the intermediate support 7, the cardan gear 8 and the spur gear 9.

When the tractor 5 moves, the working section 3 is immersed in the soil, cuts the soil layer, produces an incomplete revolution and crumbling of the layer.

Incomplete turnover of the reservoir occurs due to the angle of attack "a" of the working section 3, made equal to 20 °.

At the same time, the tractor 5, passing through an unplowed area, with its wheels 10 compacts the soil at a depth of "H" (Fig. 2), usually exceeding the plowing depth "h", depending on the weight of the tractor 5 and the total contact area of the wheels 10 s the soil. H> h.

Soil cultivators 11 in the form of canines with sharp interchangeable tips 12 mounted on the frame 1 to a depth of "H" exceeding the plowing depth "h" will loosen the soil, compacted by the wheels 10 of the tractor 5 (Fig. 1).

The support sheet 13, made in the form of a ski, will slide along the edge of the furrow, preventing soil unloading under the base of the cylindrical gear 9.

When overloads occur on the working section 3, the safety clutch 18 (Fig. 3) is activated, the drive disks 17 of which are mounted on the splines 16 of the drive shaft 14 (Fig. 4) of the intermediate support 7, from the side of the cylindrical gear 9 near the pin 15, on which the possibility of rotation is installed on the flange 19 of the safety coupling 18, to which the fork 20 of the cardan gear 8 of the cylindrical gear 9 is attached (Fig. 1).

Thanks to the installation on the track of the wheel 10 of the tractor 5 soil cultivators 11 in the form of canines with sharp replaceable tips 12, loosening of the soil, compacted by the wheels 10 of the tractor 5 at a depth of "N" exceeding the depth of plowing "h", and allows you to restore water-air soil .

The installation of the support sheet 13 in the form of a ski under the base of the cylindrical gearbox 9 made it possible to prevent soil from being loaded by the base of the cylindrical gearbox 9 and to reduce the resistance to movement of the rotor.

The installation on the drive shaft 14 of the intermediate support 7 of the safety clutch 18, has reduced the range of rotor assemblies.

The implementation of the angle of attack "a" of the working section 3 equal to 20 ° contributes to an even distribution of forces acting on the working section 3.
