Abstract

The development machine has the base frame with executive body arranged as a frame equipped with reducer with cutter crowns, hinged to hydro-cylinder for its lift and with rotary turret. It is equipped with additional removable executive body with one axial crown at the frame of which openings are provided for hinged connection with the rotary turret and the rod of the hydro-cylinder.

Description

Description of the invention

The utility model refers to selective-action trailing combines, which are intended for use in the 2 mining industry, mainly coal.

A well-known pick-and-roll combine harvester, which includes an arrow-shaped executive body with one axial crown, a receiving table with raking legs, a central conveyor and a tracked undercarriage, see prospectus of the combine harvester of the Yasinovatsky Machine-Building Plant, attached).

The main disadvantages of the well-known harvester are as follows: 70 - inefficient load of cut rock on the receiving table due to the presence of one axial crown; - limited capabilities of the harvester when notching into the soil due to the impossibility of minimal approach of the cutting crown to the loading table.

The closest to the useful model is the P110-01 combine manufactured at the Novokramatorsk Machine-Building Plant (patent of Ukraine Мо14722 dated 05.03.95, published 02.04.97 Е21С24/24). 12 This harvester is considered a prototype.

The claimed and known device have the following similar characteristics: a tunneling combine containing a basic frame with an executive body made in the form of a frame, which is equipped with a gearbox with cutting crowns and is hinged with a hydraulic cylinder for its lifting and with a rotating turret.

The main disadvantages of this combine are: - the impossibility of its use without additional excavation of the rocks that are cut for the penetration of workings with a sloping roof in mines, where the angle of the coal seam determines the geometry of the cross section; - in the case of processing the production of an arched form, the harvester is unproductively used to select the necessary amount of rock in the construction of the arch for the purpose of establishing fastening, since it is structurally impossible to provide the contour of the work in the form of an arch with an executive body with a transverse arrangement of crowns, which also narrows its technological capabilities. in

The basis of a useful model is the task of creating a walk-behind harvester with advanced technological capabilities.

This task is solved due to the technical result, which consists in the possibility of processing the slaughter both with a sloping and with a rectangular roof. at

This technical result is ensured by the fact that the tunneling combine, which contains a basic frame with an executive body made in the form of a frame equipped with a gearbox with cutting crowns and hingedly connected to the hydraulic cylinder of its lifting and a rotating turret, is equipped with an additional variable executive body with one axial crown, on the frame of which holes are made for the hinged connection with the rotating Ha turret and with the rod of the mentioned hydraulic cylinder. 325 There is a cause-and-effect relationship between the distinguishing features of a useful model and the technical result achieved.

The technological capabilities of the combine are expanded due to the fact that it is equipped with an additional variable executive body with one axial crown, on the frame of which holes are made for the hinged connection with the indicated rotary turret and with the rod of the mentioned hydraulic cylinder. The harvester, depending on the geological conditions of the slaughter C, can be used with an executive body with a transverse arrangement of crowns for tunnels of a rectangular form of production and with a variable executive body equipped with one axial crown for tunnels

From" production with inclined and arched fastening.

Prokhidnyt harvester, which is claimed, is depicted in the drawings, where: Fig. 1 shows the general view of the harvester, equipped with an executive body with a transverse arrangement of crowns (top view); - Fig. 2 shows the general view of the combine, equipped with an executive body with one axial crown o (side view); Fig. 3 shows the section A-A in Fig. 2 (hinged connection of the executive body and the rotary turret); o in Fig. 4 - a section B-B in Fig. 3 is shown (hinged connection of the executive body and the rod of the hydraulic cylinder 20 of lifting).

The mining combine contains a basic frame 1 (Fig. 1) with an executive body made in the form of a frame equipped with a gearbox 2 with cutting crowns 4, 3, hingedly connected both to the hydraulic cylinder 5 for its lifting and to the rotary turret 6.

The difference of the useful model is that the harvester is equipped with an additional variable executive body with one 29 axial crown 7 (Fig. 2), on the frame 8 of which holes O1 (Fig. 3) and 02 (Fig. 4) are made for hinged connection with with the rotating turret 6 (Fig. 1) and with the rod of the mentioned hydraulic cylinder 5.

The walker harvester works like this.

In the case of passing workings with a rectangular shape of the opening, a combine harvester with an executive body, equipped with two transversely located crowns 4 (Fig. 1), is used. 60 In the case of passage of workings with an inclined attachment, a combine harvester with an executive body equipped with one axial crown 7 (Fig. 2) is used.

To move from one production to another, the executive body equipped with two crowns 4 (Fig. 1) is dismantled and replaced with an executive body equipped with one axial crown 7 (Fig. 2).

The possibility of such replacement is provided by the fact that the frame of each executive body has holes with a diameter of 3 (Fig. 3) and 02 (Fig. 43) for the hinged connection with the rotary turret 6 (Fig. 1) and with the rod of the hydraulic cylinder 5.

Thus, by equipping the harvester with an additional variable executive body with transversely located crowns, the penetration of the workings with a rectangular cross-section is ensured, and when the combine is equipped with a changeable executive body with an axial crown, penetration is made with an inclined or arched cross-section. Thanks to this, the technological capabilities of the combine are expanding.

According to the proposed useful model, a prototype was manufactured at the Novokramatorsk Machine-Building Plant, which is successfully being tested at the Chervonoarmiyska Zahidna mine.

Claims (1)
