Description

Technical Field

[0001] The present invention relates to the technical field of coal mining machines, and more specifically, to a coal mining machine with a high-efficiency coal conveying function. Background Art

[0002] The mining industry is the foundation of the national economy. It is responsible for providing coal and various useful minerals and raw materials. With the development of my country's economy, it is required to equip mines with high-quality, high-efficiency and high-economic-efficiency mining machinery and equipment, to carry out technical transformation of the original mining equipment, and to improve the technical level of my country's mining industry.

[0003] Open-pit coal mining should try to use efficient continuous mining technology and non-transportation dumping technology to achieve continuous and efficient production and improve the productivity of the coal mining industry. The existing broken coal is piled up on the bucket structure, which is prone to blockage at the feed end of the conveying component, thus affecting the conveying efficiency.

[0004] The Chinese invention patent with publication number CN118187850A discloses a crawler-type steeply inclined continuous coal mining machine, in which two pusher blades are provided at the bottom of the inner wall of the collecting bucket, and the crushed fragments continuously fall into the interior of the collecting bucket, and are then pushed into the discharge assembly by the pusher blades and discharged from the tail end of the equipment. Although the blockage at the feeding end can be alleviated to a certain extent, due to the downward inclination of the front end of the collecting bucket and the low height of the pusher blades, it is difficult to push the coal into the discharge assembly when the collecting bucket is overstocked.

[0005] The Chinese invention patent application with publication number CN104453906A discloses a new type of continuous coal mining machine, which consists of a frame and a mining device installed on the frame, a loading bucket, a scraper conveyor, a belt conveyor, a diesel generator, a fuel tank, a traveling device and a cab. The mining device is equipped with a cutting machine with an anchor-shaped cutting head, which can be extended and lowered forward and backward by a hydraulic device; the loading bucket is installed under the mining device, and is lifted and rotated by the bucket box lifting hydraulic rods and rotating star wheels installed on both sides; the scraper conveyor cooperates with the loading bucket and the belt conveyor installed at the rear of the frame to realize material feeding. This solution still has the problem that when there is too much material in the bucket, it is easy to cause blockage at the conveying end.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example

[0049] like Figures 1 to 11 As shown, the present invention is a coal mining machine with an efficient coal delivery function, comprising a main body structure 1, a bucket structure 2 and a crushing assembly 3 are installed on one side of the main body structure 1, the bucket structure 2 is located below the crushing assembly 3, and a support structure 4 is installed on the other side of the main body structure 1;

[0050] During operation, the support structure 4 extends to support the main structure 1 to prevent the main structure 1 from sliding. At the same time, the support structure 4 is relatively distributed with the bucket structure 2, and the coal is crushed by rotating the crushing assembly 3. The crushed ore falls on the bucket structure 2.

[0051] The bucket structure 2 includes a bucket body structure 21, the main body of the bucket body structure 21 is a bucket 211, an extension plate 212 is provided on one side of the bucket 211, the bucket 211 and the extension plate 212 form a channel 213, and two through holes 215 are provided at the feed end of the bucket structure 2, a turntable 22 is installed at the through holes 215, and a transmission assembly 26 is installed on the bottom surface of the bucket body structure 21, and the output end of the transmission assembly 26 is connected to the turntable 22 through the through hole 215.

[0052] Preferably, a working motor is installed on one side of the transmission assembly 26, and a transmission gear is installed inside the transmission assembly 26. The output ends of the two transmission assemblies 26 rotate in opposite directions, and the rotating turntable 22 pushes the crushed coal in the bucket 211 to rotate into the channel 213.

[0053] The broken coal blocks falling on the bucket 211 are pushed to one side of the channel 213 by the rotating turntable 22, and the channel 213 transports the fallen broken coal to one side, thus completing the transportation of the broken coal.

[0054] In order to improve the pushing effect of the turntable, the turntable 22 includes a sleeve and three pusher claws evenly distributed along the circumference of the sleeve. A deep groove 222 is opened on the bottom surface of the pusher claw. Two rotating rollers 8 are installed inside the deep groove 222. The two rotating rollers 8 are connected by a belt 9; a rotating gear 7 is installed in the deep groove 222, and the rotating gear 7 is connected to one of the rotating rollers 8 through transmission.

[0055] The lower end of the sleeve is rotatably provided with a gear plate 6, and the lower end of the gear plate 6 is provided with a limit column 601 connected to the bucket structure 21, and the rotating gear 7 is meshed with the gear plate 6. In order to improve the supporting force of the belt 9, a plurality of supporting rollers supporting the belt 9 are rotatably provided in the deep groove 222. A cover plate 224 is installed on the bottom opening of the deep groove 222.

[0056] The rotating gear 7, rotating roller 8 and belt 9 move synchronously with the turntable 22. The gear plate 6 is fixed on the bucket structure 21 and does not rotate. When the rotating gear 7 rotates relative to the gear plate 6, it can drive the corresponding rotating roller 8 to rotate, so that the belt 9 pushes the close material to move to the side away from the gear plate 6, which is convenient for material discharge.

[0057] The bottom surface of the bucket 211 includes an inclined surface and a plane. The through hole 215 is located on the plane. The channel 213 is located on the inclined surface. The end of the channel 213 extends to the connection between the inclined surface and the plane. An inclined plate 25 is installed on the inclined surface. The inclined plate 25 is inclined toward one side of the channel 213. Both opposite sides of the channel 213 are provided with ridges 214.

[0058] Since the bottom surface of the bucket 211 is composed of an inclined surface and a flat surface, the crushed coal falling on the inclined surface slides along the inclined surface toward one side of the flat surface. At the same time, two turntables 22 are installed on the flat surface. The two turntables 22 push the crushed coal into the channel 213 to achieve rapid transportation of the crushed coal.

[0059] The inclined plate 25 facilitates the crushed coal to slide toward the channel 213 . The conveying chain plate in the conveying assembly 5 passes through the channel 213 , and the convex ridge 214 limits the moving conveying chain plate.

[0060] A stopper 24 is installed on the plane of the bucket structure 21 , and the stopper 24 is close to one side of the inclined plate 25 .

[0061] The rotating disk 22 is provided with a convex ring 221, and two baffles 23 are provided. Each baffle 23 is fixedly connected to a column 29 and connected to the convex ring 221 on the corresponding rotating disk 22 through the column 29. A cylindrical cam guide groove is provided on the inner ring surface of the convex ring 221 and the column 29, and a convex point 291 that cooperates with the cylindrical cam guide groove is provided on the column 29. Stoppers 24 are fixedly provided on both sides of the bucket structure 21, and the circumferential movement of the baffle 23 is limited by the stoppers 24.

[0062] Specifically, the inner side of the stopper 24 is an arc-shaped surface adapted to the outer ring surface of the baffle 23, and a convex column 241 is arranged on the arc-shaped surface. A groove 231 that slides with the convex column 241 is arranged on the outer ring surface of the baffle 23. When the turntable 22 rotates, the cylindrical cam guide groove is driven to rotate, and the baffle 23 is driven to move up and down by the cooperation between the convex point 291 and the cylindrical cam guide groove. An edge 242 is arranged on the upper side of the arc-shaped surface of the stopper 24, and the edge 242 limits the baffle 23 up and down. The baffle 23 is a semicircular structure, and the upper surface of the baffle 23 is a curved surface, which is lowered toward the side of the discharge end of the bucket structure 21. The baffle 23 vibrating up and down shakes off the broken coal blocks on the upper surface of the baffle 23. Since the upper surface of the baffle 23 is a curved inclined surface, the broken coal blocks slide along the inclined surface toward the side of the channel 213.

[0063] A conveying assembly 5 is installed in the middle of the main body structure 1, and a driving assembly is connected to one end of the conveying assembly 5. The driving assembly includes a driving roller 27 and a driving motor 28. The bottom surface of the bucket structure 21 is provided with two mutually parallel side plates, and a driving roller 27 is installed between the two side plates. A driving motor 28 is installed on the outer side of the side plate, and the driving motor 28 is connected to the driving roller 27. The conveying assembly 5 includes a conveying chain plate, which is connected to the driving roller 27 and passes through the channel 213. The driving motor 28 drives the driving roller 27 to rotate, and the rotating driving roller 27 drives the conveying chain plate to rotate. Since one end of the conveying chain plate is located in the channel 213, the rotating conveying chain plate drives the crushed coal blocks to move.

[0064] The supporting structure 4 includes a connecting seat 41, which is fixedly mounted on the main body structure 1. Both ends of the connecting seat 41 are connected to supporting legs 42 and a telescopic rod 43. One end of the telescopic rod 43 away from the connecting seat 41 is connected to the supporting legs 42. A tailstock 44 is mounted on the outer side of the connecting seat 41.

[0065] When support is needed, the telescopic rod 43 is extended, thereby pushing the bottom end of the support leg 42 to press against the ground, so that the support leg 42 supports the main structure 1. The tailstock 44 is distributed relative to the crushing assembly 3, and a counterweight block can be installed on the tailstock 44 to maintain the balance on both sides of the main structure 1.

[0066] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
