Description

(54) DEVICE FOR BLOCK SOIL DEVELOPMENT

I

The invention relates to the excavation and the first (the soil excavation, in particular to the earth-moving machinery, and can be used for block excavation, mainly frozen or rocky.

A device for block soil excavation is known, which contains bars of a chain mounted on a vehicle boom and a drive for rotating bar chains 1.

A disadvantage of this device is that it does not provide for excavation of the cut out block of soil from the trench without the use of auxiliary means.

The closest to the proposed technical entity is a device for block excavation, including a bar tool mounted on a support carriage and a mechanism for gripping a block of soil containing a carriage mounted on a beam connected to the carriage with mechanisms for moving it in a horizontal and vertical direction. x 2.

However, it does not provide a combination of all operations for cutting and transporting a block of soil, which leads to a decrease in the performance of the device.

The circuit of the invention is an increase in productivity by combining the operations of cutting and gripping a block of soil.

This is achieved by the fact that the bar working body is hingedly attached to the carriage, and the slekhanizm for gripping the block is made in the form of a flexible element, one end of which is fixed to the drive drum with which it supplies the beam, and the second end of the flexible element is fixed to the bar working body, while supporting the trolley is made with sides, and its supports are telescopic in a vertical plane with their extension drive.

FIG. 1 shows a device for block soil excavation, side view; in fig. 2 is the same section A-A in FIG. one.

The device for block soil excavation can be done in the form of a self-propelled cart or trailed support cart 1 to the base machine 2. The support cart 1 has boards 3 and telescopic supports 4 with a lead from their 5 extension. In the upper part of the support cart 2, a longitudinal beam 6 is simulated with a drive 7 for raising and lowering it. On the beam 6, a carriage 8 is installed with a drive 9 moving it along the beam 6. A bar tool is pivotally attached to the carriage 8, which is made in the form of an annular bar circuit 0 with a rotation drive 11 mounted on a frame 12, which also has a drive 13 turning it relative to the axis of attachment to the carriage 8. In the lower part of the longitudinal beam 6, a driving drum 14 is fixed with a flexible element 15 wound on it, one end of which is fixed to the drum, and the second is connected to the frame 12 of the circular bar chain. The flexible element 15 forms a movable bottom of the support carriage 1. The flexible element 15 can be made of a chain or a belt. In the upper part of the disputed trolley 1, clamps 16 are mounted on a posi- tion of the longitudinal beam 6. The operation of all units of the device is controlled from the console 17.

The device for block excavation works as follows.

Before excavating, the beam 6 is in the raised position and fixed in this position by the locking pins 16. The carriage 8 is set to the extreme right position, and the bar chain 13 is set to the cutting position, the flexible element being wound on the drum. The beam is then lowered until the bar chain is in contact with the ground, the shaft is turned on and rotated, and the ground is pulled along with the flexible element 15, which is unwound from the drum 14. When the vertical position is reached, the drive 9 is moved along the beam 6 and the device is turned off 13. Then, horizontal cutting of the soil is performed with simultaneous pulling of the flexible element 15 under the cutting out block of the soil. When the carriage 1 reaches the leftmost position, the actuator 9 is turned off and on: the actuator 13 rotates the frame 12 of the bar chain which is deepened, continuing to stretch the flexible element 15. After the completion of digging the bar chain, the soil block is raised together with the beam 6 and fixed in position for further transport by this device. If ishrina developed

trenches, for example, 3 times more than one passage of the device, then two trenches are developed at some distance from each other with the help of the device; The device can work with one extended support (in the case of fragments of a trench with a width equal to two passes of the device). The unloading of the block of soil is carried out in the reverse sequence of its cutting.

The use of the device allows the development of trenches of various widths in large blocks and ensures their transportation to the required distances.
