Embodiment 1

[0027] Embodiment one: as attached figure 1 As shown, the scraper conveying device includes a middle trough 6 , and rack rails 2 are fixedly installed on the sides 1 of the middle trough 6 via rack rail seats 3 .

[0028] According to requirements, the middle tank 6 includes a middle plate in the middle for carrying pulverized coal, a tank side 1 arranged on the left and right sides of the middle plate, and a bottom cover plate arranged under the middle plate, and the gear rail 2 is fixedly installed on the upper side of the tank side 1 . During use, by setting the rack 2, the shearer can walk on the scraper conveying device through the rack wheel 11, so as to avoid the phenomenon of uneven stress, jamming and inability to walk smoothly when the shearer is working, and can Improve coal mining efficiency and facilitate installation and maintenance.

[0029] According to actual needs, the above scraper conveying device can be further optimized or / and improved:

Embodiment 2

[0034] Embodiment two: as attached figure 2 As shown, the double rack scraper conveyor includes a head transmission part, a transition groove, an adjustment groove, a tail part and a middle groove body formed by a plurality of middle grooves 6 fixedly connected together, the head transmission part, the transition groove, The regulating tank, the middle tank body and the machine tail are connected together.

[0035] According to requirements, the transmission part of the head, the transition groove, the adjustment groove and the tail part are all existing known technologies. In the process of use, through such a setting, the middle trough can be produced in batches and installed in combination to form a double rack scraper conveyor, which can be combined with the coal mining machine with cutting drums on one side and the coal mining machine with cutting drums on both sides. The shearer is used in conjunction with the machine so that the shearer moves forward or backward on th...

Embodiment 3

[0036] Embodiment three: as attached image 3 As shown, the coal mining device includes a coal mining machine body and a double rack scraper conveyor. The coal mining machine body includes a coal mining machine body 7, a coal mining machine rocker arm 8 and a coal mining machine cutting drum 9. The left and right sides of the machine body 7 are provided with a shearer cutting drum 9, the shearer cutting drum 9 is connected with the shearer body 7 through the shearer rocker arm 8 and can swing up and down, and the middle groove 6 is arranged in the On the lower side of the shearer fuselage 7 at the position between the cutting drums 9 of the shearer, on one side of the lower part of the shearer fuselage 7 there is a detaining groove 10 with an opening downward, and in the middle of the detaining groove 10, a The rack wheel 11 engaged with the rack 2, the rack 2 is located in the holding groove 10, and the rack wheel 11 engaged with the rack 2 on the other side is provided on th...

Abstract

The invention relates to the technical field of coal mining equipment, in particular to a scraper conveying device, a double-toothed-rail scraper conveyor and a coal mining device. The scraper conveying device comprises middle grooves. The double-toothed-rail scraper conveyor comprises a machine head transmission part, a transition groove, an adjusting groove, a machine tail part and a middle groove body formed by the multiple middle grooves which are fixedly connected together. The coal mining device comprises a coal mining machine body and the double-toothed-rail scraper conveyor. The structure is reasonable and compact, by arranging toothed rails, the coal mining machine can walk on the double-toothed-rail scraper conveyor through toothed rail wheels, the phenomena that the coal miningmachine is uneven in stress, stuck and cannot walk smoothly in the working process are avoided, and installation and maintenance are also convenient; by arranging detaining grooves, the problems thatcoal cutter cutting rollers on the left side and the right side of a coal cutter body are uneven in stress, stuck and incapable of walking smoothly, the coal cutter body inclines, the coal cutter bodyjumps, and a coal cutter topples over can be solved, the failure rate of the coal cutter is decreased, and the coal cutting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, and relates to a scraper conveying device, a double rack scraper conveyor and a coal mining device. Background technique [0002] The traditional double rack scraper conveyor is generally one-sided rack, the other side of the scraper conveyor is equipped with a shovel, the upper side of the shearer shovel is the shearer drum, and the front of the shearer shovel is shovel. coal, this type of scraper conveyor generally has a large cross-sectional size (the cross-sectional size is generally 630mm and above), and the weight of the matching shearer is also relatively heavy. There is a cutting drum on one side, and the other side of the shearer is a walking gear mechanism that can engage with the single-side rack conveyor to travel. For the use of a single-side drum shearer with a single-side rack scraper conveyor, the force is generally not There will be problems of uneven force, sticki...
