Abstract

The invention relates to construction and m. B. Used for backfilling trenches and trenches. The goal is to reduce the energy intensity of the trenching work. Work equipment includes push frame. A working tool of rotational action with cutting teeth 8 is mounted on it. The working body is made in the form of conical screws 7 aligned with the bases with an autonomous drive of rotation. The lower generators of the screws 7 are located along a horizontal plane and mounted on an additional frame. The tooth 8 is fixed with variable aiaroM on the outer edges of the screw blades of the screw 7. The cleaning blade with a cutting concave knife 6 is made with a working surface in the form of surfaces of truncated cones arranged symmetrically relative to the average longitudinal plane of the blade of the blade. In the trench, the soil is fed transversely by a conveyor. The screws 7 with the teeth 8 more evenly distribute the load on the working equipment and reduce it, since the cross-sectional shape of the screws 7 is similar to the cross-sectional shape of the blade. Concave knife 6 reduces the effort to cut and move the soil and contributes to a more optimal supply of soil to the conveyor. 1 hp ff. 5 nl. e (L 1HE so soo oo about fig.g

Description

The invention relates to construction and can be used to fill trenches and trenches.

The purpose of the invention is to reduce the energy intensity of the operation of trenches.

Figure 1 shows the working equipment of trenchespatsel, side view; figure 2 is the same, top view; on fig.Z - the same, front view; figure 4 - support wheel, side view; figure 5 is the same, front view.

The working equipment of the trenches 1 contains a pushing frame 2, a cleaning blade 3 mounted on it, a transverse conveyor 4, a support wheel 5, a cutting concave knife 6, conical screws 7 with cutting teeth 8 on the outer edges of the screw blades of screws 7, which - the rye are mounted on the additional frame 9, the hydraulic motors 10 of the screw drive 7, the hydraulic cylinder 11, the hydraulic motor 12 of the conveyor drive 4, the fork 13 of the support wheel 5, the vertical direction yusha 14 of the fork 13, the hydraulic cylinder 15 of the support wheel 5 t3 of the support wheel 5 along the vertical guiding 14th.

The working equipment of trenching agent 1 works as follows. Using the hydraulic cylinders 11, the frame 2 of the working equipment is lowered. Driven conical augers 7, capturing the soil, feed it to the cross conveyor 4, which directs the soil into the trench. The soil supply is possible on either side with the help of conveyor 4. The transfer of working equipment from transport to working and vice versa is carried out using hydraulic cylinders 11 and 15. The support wheel 5 takes the load from the equipment mass and at the same time limits the depth of the screws 7.

Conical screws 7 with teeth 8 installed at variable pitch along their length distribute the load on the working equipment more evenly, reducing it, since the cross-sectional shape of the screws 7

similar to the shape of the cross-section of the dump 3 soil.

The concave cutting knife 6 with the edge and upper part cut inwards reduces the effort to cut and move the soil, and also contributes simultaneously with the conical shape of the screws 7 to a more optimal supply of soil to the conveyor 4.

The support wheel 5, the fork 13 of which is fixed in the vertical guide 14 with the possibility of moving along it with the help of the hydraulic cylinder 15, the pulling of the shaft which is carried out synchronously with the raising and lowering of the pushing frame 2, makes it possible to increase the maneuverability of the trench-broom 1, to reduce the load on its chassis part.
