Description

(54) WORK BODY OF THE DIGGER MACHINE

one

The invention relates to mechanical engineering, in particular, to continuous earth moving machines with a rollless working tool designed to open extended recesses of rectangular cross section.

Known working body, in which the teeth on the outer surface of the front and rear cut-off drums are installed cutting edges in opposite directions, and the teeth on the end drum are mounted in pairs on the steering knuckle and provided with cutters attached to the outer sides of the teeth 1.

However, the application of this tool to work in both frozen and thawed grounds for fragments of extended grooves is difficult.

Known working body, made of sections, equipped with cutting and transporting, their elements, containing the drive unit, and the supporting element 2.

However, this working body has a significant energy intensity of the working process and its sticking in thawed sticky soils is not excluded.

The goal of this is to reduce the metal intensity of the machine, the energy intensity of the working process and to ensure work both in frozen and thawed soils.

This is achieved by the fact that each section of the working body is made of a drum and a frame concentrically mounted with it, one of the ends of which is equipped with rotating teeth, while the frame is installed with the possibility of locking with the drum.

FIG. 1 shows the working body of the earthmoving machine; in fig. 2 - section A - A in FIG. I.

The working body consists of one or several sections. In the pro-interstitial between the sections there are: in one - the drive gearbox 1, which serves simultaneously as a support, and in the other - support 2. Each section has

5 a drum 3 and a carcass consisting of two disks 4 and transporting (remote) elements 5. The disks 4 and elements 5 carry the cutting teeth 6. On the ends of the sections rotary teeth 7 are mounted on the same elements and disks. The drums 3 can be locked

0 clamps 8.

In the development of both thawed and frozen, but not sticky soils, the drum and the frame are locked and form one whole. When the rotor rotates, the soil, cut off and broken by the teeth, is picked up by the transporting elements and removed from the bottom, discharged into the waste device (for example, into the thrower).

During the operation of the machine in sticky soils, the drums 3 are locked by the clips 8 and the conveying elements 5, together with the teeth 6 and 7, rotate around the stopped drums. When removing the soil from the bottom, the soil falling on the drum side is forcibly cleaned by the elements 5.

The swivel teeth 7 allow the tool to deepen not only in thawed but also in frozen soils by an amount equal to the diameter of the rotor. They are intended for the development of ground pillars formed in the gaps of the sections (in the case of an end drive or end support - the ground before the drive and). At the exit of the bottom, the pivoting teeth are placed on the gearbox housing or the support leg, which serve as both guiding copiers, turn around the hinges, and pass the gear housing and the leg support. After the casing and the support have passed, the tooth 7, under its own weight, becomes in the working position and enters the face like ordinary teeth 6. Thus, when opening a notch of the same depth with the same performance by known mashes and

A machine with the proposed working tool last has a smaller rotor diameter, and therefore, a smaller mass, dimensions, metal construction and, as shown by experimental studies, the specific energy intensity of the workflow.

Invention Formula

Working body, earthmoving machine, vypol.

One of the sections equipped with cutting and transporting elements, contains a drive unit and a support element, characterized in that, in order to reduce the energy intensity of the working process and ensure operation in both frozen and thawed soils, each section of the working member is made of a drum and a frame concentric with it, one of the ends of which is equipped with swivel teeth, while the frame is installed with the possibility of locking with the drum.
