SU249300A1 - DEVICE FOR DEVELOPMENT OF SOIL IN GROUND GROUND CONSTRUCTIONS - Google Patents

Description

For the development of soil in the slopes of the earthworks, devices are used that include a base machine, an arrow, a winch and a bucket with a rotary bottom.

In order to protect the sides of the canals from scouring with water, it is often necessary to remove the surface layer of the soil from the slopes and replace it with a sheen layer. The recess for the backfill should have in its lower part a ledge that acts as an abutment that keeps the layer of crushed stone from falling.

With known devices, the bucket is not designed constructively to form a fence with an emphasis, and the conditions for unloading the soil are complicated.

In the described device, in order to improve the soil unloading conditions and the formation of a step in the slope, the boom is mounted on the base machine with the possibility of rearranging the boom end associated with the machine in the vertical plane, and the bottom of the bucket is made with a cutting edge of the front edge.

The end of the boom can be mounted on the base machine in a guide post with a hole.

FIG. 3 - bucket in general; in fig. 4 - boom mounting unit in two projections.

The device contains a base machine / (tractor), equipped with a two-drum

with a winch 2, which with the help of the head 3 and tail 4 cables drives the bucket 5. It is made with the bottom edge on the front end. The bucket 5 moves on the rollers 6 along the boom 7, completed,

for example, “s pipe or I-beam. The upper end of the boom moves in a slot located in a rack 8 that has a number of holes 9. They are used to adjust and fix the boom 7 in positions that depend on the required angles of slopes. The lower end of the boom is equipped with a tail roller 10.

For lifting and lowering the boom 7, there is a manual winch 11 and a cable 12. A console 13 with a jib 14, made, for example, from a corner and a channel bar, fastens on the back to the rear axle of the base machine and serves to suspend the boom 7.

Laying of excavated soil on the crest of the slope is done by dump 15, attached to the machine by rods 16. The knife 15 is lifted to the transport position using a manual winch 17. This same winch 17 serves to change the height of the upper end of the boom. Link 18

plane, pivotally attached to the tractor and boom 7.

The operation of the device is as follows.

The device is gusting on the crest of the slope, the boom is placed parallel to the slope, with the help of winches 11 and 17.

The idle drum of the winch 2 is engaged and the bucket 5 from the upper position moves down the boom 7 (idling). The bottom 19 is put inside the scoop.

When the bucket is in the lower position, the idling drum of winch 2 is turned off and the drum of winch 2 is turned on. Bucket 5 moves upwards but the boom 7. Bottom-hole 19 of the bucket turns on axles 20 and hits the ground. 1 (0 | HS 5 is filled with soil.

When the bucket 5 comes to the upper position, the drum of the winch 2 turns off. The tension of the head cable 3 is weakened. Ladle 5 iod with own action

the weights and weights of soil in it rotates around axis 21 and is unloaded. The base machine (tractor) moves along the channel by the width of the bucket, and the cycle starts again.
