Description

The invention relates to earth moving machinery and can be used primarily for the laying of closed material drainage, as well as communication lines and other underground utilities.

The purpose of the invention is to reduce the dimensions of the working body and improve the quality of its work by eliminating dump processing of the upper soil layer.

In FIG. 1 shows a working member, a general view of FIG. 2 - section aa in figure 1; in Fig.3 is a view along arrow B in Fig.1; in FIG. - section bb in figure 1; in FIG. 5 - section GG on

figure 4; Fig. 6 is a diagram of the movement of the formation in section BB.

The working body consists of a pipe guide path 1 displaced relative to its longitudinal axis, on which the upper and subsequent one or more soil-I developing bodies are fixed, horizontally and vertically offset, each of which includes a guide element 2, conjugated with horizontal 3 and vertical k knives. The working surface of the guide element 2 following the upper soil-developing body is made curvilinear according to B-b in

The guide element 2 lifts the soil chips to a height slightly larger than the diameter of the stacked tube and rotates it through an angle of ± ± to

The guide element 5 of the upper soil-cultivating body is made flat and installed relative to the subsequent soil-cultivating body according to the dependence (gi: gf O ctgoi, where 1 is the horizontal horizontal displacement of the front edges, knives 6 and 3, respectively, of the upper and the next soil-cultivating bodies, MJ fti - the cutting angle of the horizontal knife of the upper soil-forming organ, which allows the soil to be moved to the guiding element 2 without compaction. ntal knife 6, located in the same plane with the guide element 5, which is equipped with a vertical curved divider 7, attached with its front edge to the front edge of the vertical knife 8.. The upper section of the pipe-guide tract 1 is located between the divider 7 and the vertical knife 8.

The development of soil by the working body is as follows.

With the translational movement of the working body in the direction shown in Fig. 1 by the arrow, the guide element 5 of the upper soil working body cuts and raises the soil layer. A drainage tube is sold along the pipe guide 1, and the next soil-cutting organ cuts out soil chips of thickness h and width B with knives 3 and A, which travels along the curved guide element 2 and sprinkles the laid pipe.

The working body has the minimum dimensions when installing the horizontal knife 6 of the upper soil of the working body at the critical depth of cut (hKp in Fig. 1).

Acquisition Formula

Excavation working body of a trenchless drainage layer, including a guide pipe displaced relative to the longitudinal axis of the working body and soil-cultivating bodies mounted on it with horizontal and vertical displacement, each of which is made of a guide element paired with vertical and horizontal knives, and the working the surface of the guide element of the soil-cultivating organ following the upper one is made curved according to the dependence Bb h-К,., where B is the width of the horizontal knife, m; b is the width of the pipe-guide tract, m; h is the vertical displacement of the leading edges of the horizontal knives of the upper and subsequent soil-cultivating organs, m; Kr is the coefficient of increase in soil volume (loosening) during development, characterized in that, in order to reduce the dimensions of the working body and improve the quality of its work by eliminating dump processing of the upper soil layer, the guide element of the upper soil-developing body is made flat and is located in the same plane with the horizontal knife, and in the upper soil-forming body is equipped with a vertical curved divider attached with its front edge to the front edge of the vertical knife, and the pipe the guiding path is located between the divider and the vertical knife, while the relative position of the upper and the soil-working bodies placed at the same time corresponds
