Description

The invention relates to earthmoving machines, in particular, a drilling tool working body for an earthmoving machine, which can be used to dig channels, trenches, erect dams, dams, to open and develop a field to ensure selectivity by drilling and crushing the ground mass of broken ground.

The purpose of the invention is to increase productivity.

Fig, 1 shows the working body, front view; in fig. 2 - working body from the side of the support frame, general view; in fig. 3 shows section A-A in FIG. one; in fig. 4 - section bb in figure 2; in fig. 5 - half-tusk with safety device, isometric projection; in fig. 6 - polukonsh with protective device, top view; in fig. 7 - safety device, isometric projection; in fig. 8 is a diagram of the work of the working body. The working body consists of a support frame 1, an outer faceplate 2, an inner faceplate 3, a locking flap 4 with a receiving and feeding platform 5, fixed below in front of two parallelly arranged driven drums of belt conveyors of the left 6 and 7.

The outer faceplate 2 is a round rotor with beams 8 fixed on the hub of a hollow shaft 9 located on the platform of the supporting frame 1. On beams 8 bent towards the working side, a flat ring 10 with teeth 11 is fixed parallel to the shaft 9 fixed outside rings. Around the ring 10 n bent peripheral ends of the rays 8 are fixed polukushki 12 with one side wall 13.

The side wall 13 with the teeth 14, the bottom 15 with a flat knife 16 and the rear wall 17 of the semi-bump 12 are tilted outwards. The lower half of the rear wall 17 has the same width, its upper half gradually tapers towards the ring 10. The side wall 13 and the rear wall 17 are interconnected rounded to each other and form an obtuse angle.

A protective mechanism is located behind the semi-kusha 12 that protects the back of the semi-kusha 12 from nalip20

no soil. The rear cage mechanism consists of an inclined plate 18 with a notch 1 9 connected by a back edge to the rear edge of the back wall 1 7 semicircles 12. A notch 19 is closed by a rotary plate 20 connected to the inclined plate 18 pivotally, for this purpose the eyelet 21 and a finger are fixed on the plate 18 22, and under

10 rounding in the upper part of the rotary plate 20 is fixed, respectively, the finger 23 and the eye 24.

From the rear of the semi-kusha 12 to the upper rear plane

15 of the pivot plate 20 is fixed to the rail 25, and one end of the chain 26 is attached to the middle rear plane of the rotary plate 20, the other end of which is attached to the rod 27 attached to the rear of the semi-ember 12 to the peripheral end of the beam 8 and to the rear plane of the inclined plate 18.

Scrapers 28 are fixed to the horizontal part of the beams 8. At the bottom, behind the semi-knob no. 1 12 on the supporting beams 29, fixed on the supporting frame 1, the locking flap 4 and the receiving-feeding pad 5, consisting of a peak 30, welded to the upper rounded edge the locking plate 4, and from the inclined tray 31 with side walls 32 welded by the front edge to the horizontal edges of the locking plate 4 and to the visor 30. The rear is horizontal

35, the edge of the tray 31 is located above the driven drum of the belt conveyor belt 6 and 7. At the bottom, two horizontal blades of the blade form 33 with teeth are fixed to the locking plate 4.

Above the receiving and feeding platform 5 on the shaft 35 are fixed beams 36 of the inner faceplate 3 with bent peripheral ends to the side

 rings 10. On beams 36, a tooth 37 and scrapers 38 are fixed.

On both sides of the mine are rotors 39 with open-type buckets 40, equipped with teeth 41 s.

fixed in the middle of the common shaft 47 screw cutters 48 with right and left winding, located between the belt conveyors 6 and 7 and the rotors 39. Inclined trays 49 are located in the cavity of the rotors 39, and stripping devices 50 are located behind the rotors and screw cutters.

The working body works as follows.

Rotating clockwise, the faceplate lowers the half-heads 12 to the right. In the lowered semi-chain B into the chain, 26, with its weight, presses the edge of the turntable plate 20 to the vertical plane of the working. On the inclined plate 18, which is constantly pressed against the front edge, and on the rotary plate 20, which is temporarily pressed against the vertical plane of the excavation, a part of the soil connected with the half-hinge A falls. Slipping along inclined planes 18 and 20, it falls onto tray 31 through the rear edges of the plates. Most of the soil, cut by the half-A, falls on the receiving and feeding platform 5 through the ring 10. The whole mass of the soil cut by the half-B, drops onto the plates 18 and 20 of the half-C and, slips along their inclined planes through their rear edges, falls into the tray 31, from tray 31 to the conveyor belt 7. When the rear edge of the plates 18 and 20 of the semi-dome C drops below the horizontal edge of the locking plate 4, then the soil cut by the semi-dome B, also lowered below, falls through the plates 18 and 20 to the outsole, where it is picked up and loaded by the same semi-ark lice 6. The soil cut by the half C falls right on the sole of the working where the same half half is selected.

The soil, cut off by the half-horse, falls into the same half-horse, partially loaded with soil. Advance into the depth of the polukusha L, the primer rubs against the plane of the locking flap 4, which plays the role of the second side wall of the semikushka 12 here.

the ticking plane of the working and from the foot of the working, leaving a ground on it between the bucket and the plate.

10 extends from the semi-kukush to the tray 31 and, slipping along its inclined plane, enters the conveyor 6. Soil, middle of the semi-tuft W, slipping along the free planes of this semi-bump

15 from the ground, falls on the tray 31 partly through the half-E, partly through the ring 10. The weak ground, cut from all sides by the half-ears, 12 in the center of the bottom, falls on itself

20 receiving and feeding pad 5, and the tooth 37 of the inner faceplate 3 only regulate the collapse.

From the ring 10 and from the visor 30, crushed soil is fed to tray 31

25 by scrapers 28 and 38. The strong soil is destroyed by the teeth 37 of the inner faceplate 3. From tray 31, the soil falls onto the conveyor belts 6 and 7. The scrapers 28 and 38 feed the soil on the dots

20 31, at the same time, the ring 10 and the visor 30 are cleared of soil. Knives 33, mounted on the locking plate 4, align the platform in front of the driven drums of belt conveyors 6 and 7. Screw milling cutters 48 with right and left windings located in the same plane with the blades 33, The ground is expanded, and the cut soil is fed under the rotating buckets 40 of the rotors 39, located in the same plane with the blades 33 and screw cutters 48. The rotors 39, rotating upwards, form the side walls of the excavation in the direction of the bottom.

and the soil they cut, along with the soil cut by screw cutters, is fed up and unloaded on inclined trays 49. Slides along their inclined plane, the soil falls on conveyors 6 and 7. The stripping unit 50 cleans the outsole behind the screw cutters 48 and rotors 39.
