Abstract

The invention relates to mining equipment, namely, a drum-type actuator (IO) with a vertical axis of rotation. The goal is to increase the loading capacity of the EUT. The drum EI includes upper and lower parts 1, 2 connected to the drive by means of a cutting and driving chain 3 mounted on bar 4. The cutting chain 3 and cutters 6 are mounted on the cutting chain 3 and parts of the drum IO. Cutting chain 3 is made with sections 9, not having cutting elements. Sections 9 are located in increments equal to the installation step of the loading blades 8 on the lower part of the EUT. The coal destroyed by the incisors 6 is loaded onto the conveyor with vertical blades 7 and a cutting-driving chain 3. In the lower part 2 of the EUT, the coal is loaded with loading blades 8 into the window. The presence of sections 9 on the cutting-drive chain 3 prevents the seizure of coal. 5 il.

Description

The invention relates to mining, namely to a drum-type actuator with a vertical axis of rotation.

The aim of the invention is to increase the loading capacity of the executive body.

FIG. 1 shows a general view of the drum executive body of the shearer in perspective; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 is a view of B in FIG. 3; in fig. 5 is a view of FIG. one.

The drum executive body of the shearer contains upper 1 and lower 2 parts connected to a drive (not shown) by means of a cutting and driving chain 3 mounted on bar 4. Fists 5 with cutters are mounted on cutting chain 3, upper 1 and lower 2 parts of the drum 6. On the upper part 1 of the drum, vertical blades 7 are fixed, on the lower part 2 of the drum there are loading vanes 8. In the cutting and driving chain 3 there are gaps 9, consisting of 10 links 11 and 12 connected by means of fingers. Step Tr equal to the pitch of installation of 8 T blades on the lower part 2 of the drum and is located above the upper part 13 of the blade 8 of the lower part 2 of the drum and under the vertical blade 7 of the upper part 1 of the drum.

Drum executive body of the shearer works as follows.

The rotation from the drive is transmitted through the cutting-driving chain 3 mounted on the bar 4, the upper and the lower 2 parts of the drum. The drum, rotating, produces the destruction of an array of coal with incisors 6 installed in the fists 5. Destroyed coal is loaded onto the bottomhole conveyor (with board height H with vertical blades 7 of the upper part 1 of the drum and cutting-edge

a water chain 3. In the lower part 2 of the drum, coal is loaded with loading blades 8 into a window bounded above by the bottom plane of bar 4, and below by a shelf of the bottomhole conveyor. The ruined corner filling the lower part 2 of the drum moves along the blade 8 to the cutting-drive chain 3 and enters the top part 13 of the blade

8. Due to the fact that the spacing of the lumens 9 is equal to the installation pitch of the blades 8 and the gaps 9 in the chain 3 are located above the upper part 13 of the blades 8, jamming of the coal in this zone is prevented by passing it from the lower part 2 of the drum to the upper part 1 through the lumen

9. Coal, transferred to the upper part of the drum 1, is loaded onto the conveyor with vertical vanes 7 with less energy consumption. This eliminates the reduction in the working volume of the lower part 2 of the drum due to the absence of sticking of the upper part 13 of the blade 8 by the unloaded coal, which contributes to an increase in the loading capacity of the drum. The link 11, 12 of the cutting chain 3 has the ability to rotate relative to the fingers 10, which makes it possible to change the basic parameters of the cutting chain 3 and does not reduce its efficiency.

The application of the invention allows to increase the loading capacity by 15-20% and reduce the loading capacity of the drum of the executive body by 12-15% by reducing circulation and eliminating coal seizure.

in the area of the drive chain. This is achieved due to the "transfer of a part of coal from the lower part of the drum through gaps in the bar chain, which causes the loading of this part of the coal with less energy and the absence of sticking of the upper part

drum blades with broken coal. The latter allows to increase the working volume of the lower part of the drum, and consequently, its loading capacity. The absence of sticking of the blades of the drum to the unloaded coal reduces the specific energy consumption of its loading by the lower part of the drum, as well as the circulation of coal in it.
