Description

one

The invention relates to the field of earthmoving machinery, in particular to excavator-dredgers with a working body, intended for laying the drainage tube in a trench.

Known working body of the excavator-draining machine, in which parallel to the chain working body is a device for the passage of the drainage tube 1.

A disadvantage of this device is that when the digging depth and the angle of rotation of the working member change, the device for passing the hanging tube also changes its position relative to the bottom of the trench, and therefore the drainage tube, the output from the device, forms a loop. Ground penetrates into the gap between the tube and the bottom of the trench, thereby disrupting the drain profile.

The excavator-plowing machine is also known, the working equipment of which includes an earth-moving chain working body, an upper frame with a support and a stripping shoe, a forward chute for a drip pipe, a pressure roller and a casing at the lower end of the upper frame under the support shoe 2.

The disadvantage of this device is that it has a turning part of the bottom

bunker-stacker - a ski that clogs when working with soil from the side of the implement through the hinged part, as a result of which, due to the lack of rotation of the ski, the incline control system is out of order.

The purpose of the invention is to increase the reliability of the equipment by cleaning the inside of the upper frame from the soil.

This is achieved by the fact that in the front wall of the stripping shoe there is a cutout, over which the protrusion is reinforced, the arc of the visor is back, and the support shoe is made with an inclined wall in the shape of the notch.

FIG. 1 shows the working equipment of the excavator-draining machine; in fig. 2 — node I in FIG. one; in fig. 3 - Sschenpe A-A in FIG. 2; on . 4 is a section BB in FIG. 2; in fig. 5 - support shoe, axon.

The working equipment of the excavator-pulling machine consists of an earthmoving workshop orgia 1, above which is placed the upper frame 2, which in turn consists of a frame with a groove 3, an area with a bracket for the coil with a tube 4, a stripping shoe 5, an arc visor 6, a support shoe 7 , cylinder cylinder 8, pressure roller 9 and the casing above the support shoe 10.

The upper frame 2 is intended for the penetration of the drainage tube, which runs along the guide groove 3 located inside the upper frame. The drainage tube is fed from a reel mounted on a bracket with a pad. The tube at the exit pz of the upper frame is pressed to the bottom of the trench with a roller 9 fixed to the walls of the support shoe 7.

A stripping shoe 5 is installed on the lower end of the upper frame for stripping trapped inside the ground, the knife has a base and can be adjusted.

When the trench depth or cutting angle is changed, the support shoe, having a hinge, is set to the desired position with the help of a hydroclip 8, according to the slope of the trench bottom. At the same time, the soil that fell inside the frame is pushed through a special cutout in the front wall of the stripping shoe by the inclined front wall of the support shoe. This achieves the ability of the support shoe to operate in automatic mode and maintains the specified slope.

For the direction of the ground when pushing over the notch, a protruding

back arc visor 6. From soil penetration from top to inside the upper frame of the lower part of the latter, supporting bashmak with a pressure roller and hydraulic cylinder are enclosed by a casing 10.
