Description

The invention relates to earth moving machinery, and in particular to devices for loosening soil and rocks.

Known attachments, earth moving machinery, including a bracket rigidly connected to the tractor, a working body installed in the boron. gearboxes, transfer gearbox and power cylinders pivotally coupled to the tractor unit. ''

The disadvantage of this design is its complexity and high metal consumption.

The hinged equipment of a cultivating earthmoving machine is also known, including a tractor with an arm fixed on it, a working body mounted on the output shafts of final drives, and 2 power cylinders for controlling the working body pivotally connected to the tractor l2].

However, such equipment has low reliability.

The purpose of the invention is to increase the reliability of equipment.

This goal is achieved in that the final drives are connected to the power cylinders and pivotally connected to the bracket. 3

In addition, the junction of the power cylinders with the final drives is located below the hinge for connecting the final drives with the bracket.

The drive control the working body can be made in the form of a power cylinder mounted in the plane of the longitudinal axis of symmetry of the working body.

In FIG. 1 shows a machine general view; in FIG. 2 - kinematic diagram of the drive of the working body.

Attachments include a tractor 1, an arm 2 mounted on the rear axle of the tractor, a power take-off gear 3, a transfer gear 4, final drives 5, a power tool 6 and power cylinders 7 for controlling the power tool.

The power take-off reducer provides two speeds of rotation of the working body and is equipped with a safety clutch.

The power cylinders 7 are installed below the axis of connection of the final drives 5 with the bracket 2. The control can be carried out by one cylinder mounted in the plane of the longitudinal axis of symmetry of the working body (Fig. 2 is shown by a dashed line).

The equipment operates as follows.

The drive rotates the working body 6. The power cylinders 5 (cylinder) 7 working body · lowers to the ground and deepens into it. When this occurs, the retraction of the rods (rod), which increases the reliability of the device. When moving the tractor 1, soil development is carried out.

The output of the device from the operating position is performed in the reverse order. fifteen

Thanks to the articulation of the final drive gears with the bracket 2 and the installation of the transfer gear 4 on the axis of the hinge of the bracket 2, the tipping moment arm and the flexibility of the structure are reduced. Therefore, its lengthy oscillations in operation are also reduced.

Reduced tipping torque eliminates the need for a counterweight. A general decrease in the metal consumption of the structure reduces the cost of power for movement. The simplicity of the drive mechanism of the working body reduces power loss in the drive. In general, reducing overhead costs contributes to an increase in machine performance.

In the case when the working body is controlled by one power cylinder installed in the plane of longitudinal symmetry of the working body, additional loads are eliminated due to unequal resistance at the edges of the working body, as well as the non-synchronization of the rods.

(54) HINGED EQUIPMENT OF THE RIVERING OF THE DIGGER MANIMA of the dolina axis of symmetry of the working body (in Fig. 2 is shown by a dashed line). The equipment works as follows. The rotational drive of the working org. Is turned on. With the power cylinders (cylinder) 7, the working organ is lowered onto the ground and deepened into it. When this occurs, the rod is pulled in (rod), which increases the reliability of the device. When moving the tractor 1, the excavation is carried out. The device is taken out of its working position in the reverse order. Due to the swivel joint of gearboxes with bracket 2 and the installation of transfer gear 4 on the hinge axis of bracket 2, the tilting moment of the tilting moment and the flexibility of the design are reduced. Therefore, its length fluctuations in operation are reduced. Reducing overturning moment eliminates the need to install a counterweight. The overall reduction in metal construction reduces the cost of power to move. The simplicity of the actuator drive mechanism reduces power loss in the drive. In general, a reduction in overhead power contributes to an increase in machine productivity. In the case when the working body is controlled by one power cylinder installed in the plane of the longitudinal symmetry of the working body, additional loadings caused by unequal resistances at the edges of the working body, as well as non-synchronous operation of the rods, are eliminated.
