Description

The invention relates to mining combines with a cutting chain bar, a rotating air drum and a conveyor belt. In the proposed mining combine, the transmission system with the help of bevel gears and the shaft serves to set in motion the cutting chain of the bar, and for B1, the baffle drum and the conveyor drums are conveyor-driven with the help of bevel gears, gtskyvy and cross-belts. According to a modification of the invention, a system of bevel gears and a Gall chain was used to set the cutting chain of the bar and to rotate the drums of the conveyor, and a frame with teeth with a rocker arm driven by two hydraulic cylinders was used to break the coal.

In FIG. 1 depicts a view of a mountain complex. On the side; FIG. 2 - view from above; FIG. 3 is a front view of it; FIG. 4- side view of the modified combine; FIG. 5 - view from above.

The proposed mining harvester (FIGS. 1-3) consists of an annular bar, 55, equipped with a cutting chain 6, a rotating rotary drum 2 and a conveyor J9 for feeding coal to the cutting table 28 and the conveyor 57. The demolition mechanism is placed on the frame 7. Driving the cutting chains 6 bars 55,

provided with teeth 5 arranged in a shakham order, carried out by means of bevel gear 9 and 70; the latter are seated on the shaft 72 with three torches 77 fixed on two cutting machines 8 and 25. The gear 9 is seated on the roller 75 coming out of the center of the cutting part.

The drum 2, fitted with fender teeth 4, is mounted on a shaft 15 rotating in ball bearings 77. Gears 14 14 and 32 are mounted at one end of shaft 75 and are connected by means of a cross belt 18 with pulleys 76 and 24, p. the purpose of rotation of the drum 2 and the drums 22 and 26 of the conveyor 19.

The cutting chain 6 is connected to the star 7, by means of which the annular bar 55 is set in motion.

In the lower part of the bar 55, sheet 20 is riveted, along which coal moves to the firing mechanism.

The combine is set in motion by two machines 8 and 25. When machine 8 is working, cutting chain 6 will go along the upper part of bar 55 and carry the bayonet down to 36, and from the latter onto sheet 20. When the chain goes from the bottom, then bayonet from pan 57 it goes to conveyor 19, p. which comes on reshtak 28 and further to the conveyor 57.

According to a modification of the invention, the rotation of the cutting chain b with the teeth

and the drums 22 and 26 of the conveyor / P are achieved by using a system of bevel gears 5, 2 and 27 and a chain of Gall. For beating the coal, there is a frame 29 with teeth 30 with a rocker arm 32 driven by two hydraulic cylinders 38 and 39.

The movement of the combine is done from the cutting machine and, in part, through the auxiliary winch.

The subject matter of the invention.
