SU107328A1 - Coal Combine Milling-Scaling Action - Google Patents

Description

The coal milling machines of the milling-cutting action for narrow-pit shuttling of hollow falling seams with regulation of the executive body are known for the thickness of the seam.

A feature of the described combine is the execution of its executive body in de disc milling machines located in several Rus with a set of teeth and breakaway cams, the number of which is determined by the width of the grip and the strength of the coal.

FIG. 1 shows a general view of the combine; on phpg. 2 - executive body; in fig. 3 - kinematic scheme of the combine.

The coal milling machine combining action consists of the electric motor E, the reducer of the cutting part P and the reducer of the feed part I with two drums. The actuator F is a head, on the three cantilever shafts of which there are two cutters. The body of the combine has a carrier, with the help of which the combine moves directly along the scraper conveyor. The sled carries O-blades alternately attached to one side or the other, depending on the direction of the combine's stroke, which serve to load the coal onto the conveyor and clean the soil from the ground. Combine mon; em to work on the shuttle method, as well as in the selected direction alone.

The cutters have teeth / fixed on spring holders 2, wedge-shaped breakers 3 and auxiliary teeth 4, which cut through the space for passage of the cutter hub. On the milling shafts there are rings 5, with the help of which a different distance is obtained between the mills and the thickness of the coal strip.

The kinematic scheme of the combine provides the following device of the combine.

From motor E, rotation is transmitted by means of two spur gears 6-7.

and two bevel gears S - 9 of the cutting and feeding parts of the combine. A pair of gears 10 - I serves to change the cutting speed, and through the cam clutch J2, the rotation is transmitted to the pinion gear 13 of the milling head, where there is a system of driven and parasitic gears rotating the cutter shafts F. and from it, with the help of two ratchet mechanisms 15, the rotation of the gears 17, 18 to 19 is reversed to the drums B of the feeding part. The snoring wheels have cams that engage with the cam clutch 16. With the help of ratchet mechanisms, different combine feed speeds are obtained.

Claims (2)

1. A coal milling machine for milling shuttling hollow falling seams with control of the executive body according to the seam thickness, characterized in that, in order to reduce the specific energy consumption and increase the feed rate, its executive body is made in the form of multi-section disk cutters teeth and breakaway cams, the number of which is determined by the width of the grip and the strength of the coal. 2. Form of execution of the combine pop. 1, so that, in order to obtain a stepped bottom shape, the milling discs are arranged in steps, and the control of the actuator for the thickness of the reservoir is carried out by means of a slider-lever mechanism. s Ns 107328 FIG. one about CJ iP.
