This invention relates to tamping devices for pits. The purpose of the invention is to increase the reliability of work.

FIG. 1 shows the proposed device, a general view; in fig. 2 - gripping and dropping mechanism, closed position; fig.Z - the same, the open position; in fig. 4 is a view of L in FIG. 2

The tamping device of the trenches contains a base machine 1, a guide 2, the upper part of which is connected to the machine 1, a tamper 3 with a hook, a gripping-dumping mechanism 4, made in the form of a traverse 5 with hook-grapples 6, located on both sides of the traverse 5 and pairwise-hinged on it fixed. The rollers 7 are in contact with the inner curvilinear surface of the upper part of the gripper brackets 6. The rollers 7 are placed in the lugs 8 of the hydraulic cylinder rods 9 rigidly fixed on the traverse 5. The lower ends of the gripper brackets 6 are provided with rollers 10 that come in contact with the double rollers 11 mounted in the brackets 12, which are fixed on the tamper 3.

The device works as follows.

The guide 2 is connected to the base JIOBKOM of the base machine 1 and is shifted to the vertical operating position. I. The traverse 5 moves down along the guide 2, while the gripping brackets 6 are in the open position, the rollers 7 are lowered. The gripping mechanism 4 by the rollers 10 engages with the rollers 11. The rollers 7 are driven by hydraulic cylinders 9,

in contact with the internal curvilinear surface of the anchors 6, until it stops, rolling into the groove formed. The traverse 5 with the gripping-dumping mechanism 4 and tamping 3 rises to a predetermined height, after which the cylinders 9 rolls the rollers 7 out of engagement with the upper part of the gripper brackets 6, rolling around their inner surface and moving into the extended part of the groove. At this moment, due to the action of the force of gravity from the mass of the tamping 3 on the lower ends of the gripper brackets 6, the rollers 10, in contact with the rollers 11, push the lower ends of the brackets of the grippers 6, and the tamper is dropped down. Then the cycle is repeated.
