Description

The invention relates to earthmoving equipment and can be used in the passage of trenches and pits.

A well-known machine for digging trenches ”contains a frame pivoting about a horizontal axis with a chain working body including cutting and soil transporting elements [1].

Another well-known technical solution is a machine for digging trenches and ditches, containing a tractor, a rotating frame attached to it with a rotary soil thrower and a chain working body rotatable relative to the horizontal axis, including endless traction chains with elements cutting and transporting the soil on them [2].

The disadvantage of this machine is that increasing the angle of inclination of the working body relative to the plane of the bottom of the excavation in order to increase the depth of trenches and trenches deteriorate the conditions for entering the developed soil into the thrower, and at angles of inclination close to 90 ° It becomes impossible, since separating from the working body

under the action of inertial force, the ground receives a trajectory of movement that is parallel to the thrower.

In order to increase the depth of the trenches and trenches to be torn by providing ₅ dachas of developed soil to the thrower while increasing the angle between the axis of the working body and the bottom plane of the excavation formed in the ground between the working body in the direction of ground movement, a shield attached to the frame of the thrower is installed; surface that faces the thrower.

In order to change the path of movement of ground connection to shield thrower frame formed by the axis and the retainer ¹⁵ which are attached to opposite ends of the panel.

The proposed technical solution is ensured by increasing the depth of trenches and trenches torn in thawed and frozen soils.

elements 7 and transporting soil

elements 8. Frame 2 contains a vertical axis 9. The working body 4 contains a horizontal axis 10, which is the geometric axis of the bending of the traction chains 6.

On the frame 2 of the working body through the axis 11 and the latch 12 is installed flap 13, ⁵

the concave surface 14 of which faces the thrower 3. The thrower has a frame 15.

When moving the pulling chains 6 cutting elements 7 develop soil and conveying elements 8, ₁₀ is moved out of its bottom, forming a trench.

When entering a portion of the traction chains b curved relative to the horizontal axis 10, the transporting elements 8 change the direction of movement, and the ground continues to move in the previously received direction until it encounters the thrower 3 or the flap 13. Reflected from the concave surface 14 of the flap 13, the ground enters thrower 3.

When the frame 2 is rocking relative to the vertical _2C axis 9, the working body 4 forms a wide trench in which the tractor 1 can be placed for repeated passes in order to form trenches.

The progressive movement of the tractor 1 provides the required length of 25 trenches to be torn off and trenches.

When turning the flap 13 relative to the axis 11, it is possible to select the desired trajectory of the soil entry into the thrower, depending on the properties of the soil being developed. In addition, if necessary, provides easy access to the surface 14 for ease of cleaning from adhering soil, as the latch 12 secures the flap 13 in the desired position.

Claims (2)

Claim 1. A machine for digging trenches and trenches, containing a tractor and a pivoting frame attached to it with a rotary soil thrower and a chain working body pivoting relative to the horizontal axis, characterized in that, in order to increase the depth of trenches and trenches to be reached by ensuring that the developed soil is fed into the thrower when increasing the angle between the axis of the working body and the plane of the bottom of the excavation formed in the ground, between the working body and the thrower in the direction of movement of the soil in the thrower there is a metat attached to the frame A plate having a concave surface which faces the thrower. 2. Machine for π. 1, characterized in that, in order to change the trajectory of the soil, the shield is connected to the frame of the thrower by means of an axis and a clamp, to which the opposite ends of the shield are attached.
