Description

The invention relates to machines for the development of soil, and more specifically to the working bodies of rotary excavators for the development of trenches, aggregated to tractors or tractors. A working tool for the development of rocks is known, including a rotor mounted on a frame with buckets and a conveyor 1 passing in its cavity with the possibility of embracing the rotor. The disadvantage of this working body is that it cannot transport to the outside and the specified distance from working body. Closest to the invention is the digger’s organ, which includes a frame-mounted rotor with buckets and an annular transport mechanism that encloses the rotor 2. The disadvantage of such a working body is that the bucket soil is unloaded gravitationally into the feeder, which does not allow apply it to trench excavators. The aim of the invention is to expand the technological capabilities of the working body by digging out both channels and trenches of great depth. The goal was achieved by the fact that in the working body a trencher, including a rotor mounted on the frame with buckets and an annular transport mechanism covering the rotor, the annular transporting mechanism is made of two rings interconnected by means of blades, and the rotor frame is rigidly connected with it An A-frame, on which an annular transport mechanism is installed, wherein the sides of the A-frame are interconnected by means of a transverse beam with a damping mechanism. In addition, the blades are connected to the rings by means of a torsion shaft, one end of which is rigidly connected to the rings and the other hingedly, and each of the blades is connected to the torsion shaft hingedly from the side of its rigid attachment to the side ring and rigidly from the side of the wider connect it with a side ring. FIG. 1 shows a rotary working body of a trencher, a general view, in FIG. 2A-A in FIG. one; in fig. 3 - frame transporting working body; in fig. 4 - blade fastening assembly of the transporting working body on the rings of the thrower rotor; in fig. 5 is a section BB in FIG. 4. The working body of the trough digger includes a rotor 1 with buckets 2, supported on rollers 3, which are hinged on frame 4 of rotor 1. This frame is in turn rigidly attached to frame 5 of the base machine, the vertical stands 6 of which are brackets for A-shaped frame 7 of the annular transport mechanism 8, made in the form of a material scoop (part of the torus). The rotor 1 and the transport mechanism 8 are mutually clad, together constitute intersecting working bodies. The transporting mechanism 8 consists of transverse blades 9, two side rings 10, which rest on rollers 11, which sit along the A-frame 7. The latter is fixed rigidly by one side 12 and the other is supported on longitudinal beams 13, the frame 14 5 excavators. The actuator 15 is located in the upper part of the vertical stand 6. The sides of the 12 A-shaped frame 7 are interconnected by a transverse beam through a damping mechanism in the form of, for example, springs 16. The blades 9 are fixed on the side rings 10 using a torsion shaft 17, forming a rotor thrower. The torsion shaft 17 with the side rings 10 is rigidly connected on one side with a screw 18, on the other hand hinged. The blade 9 is mounted on the torsion shaft 17 and is attached to it on one side where the torsion shaft 17 is connected to the hinge-ring 10, and on the other where the torsion shaft 17 is connected to the ring 10 rigidly-hinged. Thus, the joints of the blade to the torsion shaft and the torsion shaft to the ring are opposite in rigidity and articulation to ensure good operation of the torsion shaft: the longer the shaft, the less its rigidity and thus the impact of the soil on the blade is softer. Under the annular transporting mechanism 8 is located the housing 19, which prevents the fall of the soil from the unloading zone into the trench when the transporting working body operates in the mode of gravitational unloading. The working body of the trench rotor excavator works as follows. The soil is developed and transported to the unloading zone by the rotor 1. After unloading by the blades 9 of the transport mechanism 8, the soil is thrown to the side due to centrifugal forces. In this case, the direction of the ejection of the soil can be controlled by increasing the angle of girth of the thrower 19 of the thrower rotor and by changing the direction of rotation of the latter. When overloaded, the blades 9 can deviate from the perpendicular position from the axis of rotation, overcoming the force of the torsion shaft 17, and the blades can be angled to the direction of their movement.

In the unloading zone, under the rotor buckets, only the working branch of the ring transport mechanism is located, and the idle branch is outside the unloading zone. Thus, the discharge zone requires less vertical space, and it is possible

lower the rotor down to increase the depth of the trench.

This design of the working body and the transport mechanism allows to expand its area of application and to ensure an increase in the depth of digging.
