Description

Technical Field

[0001] This utility model belongs to the technical field of mining machinery and equipment, specifically relating to a crushing device for an open-pit continuous coal mining machine. Background Technology

[0002] In open-pit coal mines, continuous coal mining machines are widely used as an important type of mining equipment for the efficient and low-cost mining of thin coal seams. This equipment continuously cuts the coal seam using its front-end cutting mechanism. The mined coal is transported via its own scraper conveyor and belt conveyor system, and finally unloaded onto transport trucks, achieving continuous and mechanized coal transportation.

[0003] Currently, most open-pit continuous coal mining crushers use a motor-driven, reducer-driven transmission system, with the motor and reducer positioned outside the crushing drum. While this external power transmission structure is simple and easy to maintain, it has significant spatial layout defects: the motor and reducer occupy a large amount of horizontal and vertical space, resulting in poor overall machine compactness. This is especially problematic in space-constrained open-pit continuous coal mining machines, severely restricting the rational layout of other functional modules (such as conveying systems, hydraulic systems, and electrical control systems) and reducing the overall space utilization rate of the equipment. Utility Model Content

[0004] In view of the various shortcomings of the existing technology, a crushing device for open-pit continuous coal mining machine is proposed to solve the technical problem of low space utilization caused by the motor and reducer being installed on the outside of the crushing drum in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A crushing device for an open-pit continuous coal mining machine includes a drum. Inside the drum, a motor and a reducer are driven and connected. The power output end of the reducer is driven and connected to the drum. Cutting teeth are provided on the surface of the drum. A cylinder body is provided around the motor. An external spray nozzle is provided on the cylinder body. The cylinder body and the drum can rotate relative to each other.

[0006] The technical solution is further configured such that the power output end of the reducer is connected to the support shaft via a drive disc, the drive disc is connected to the roller, and the support shaft is rotatably mounted on the first support frame.

[0007] The technical solution is further configured such that the motor is mounted on a second support frame, the second support frame is positioned opposite to the first support frame, and a protective cover is provided between the two.

[0008] The technical solution is further configured such that the protective cover is connected to the first support frame via a first connector, the first connector is arranged in a vertical direction, and a first gasket is provided between the protective cover and the first support frame.

[0009] The technical solution is further configured such that a pad is provided on the first support frame, a second connector passes through the pad and abuts against the first support frame, a locking element is provided on the second connector, and the second connector is arranged in a horizontal direction.

[0010] The technical solution is further configured such that the pad is connected to the first support frame via a third connector, the third connector is arranged in a vertical direction, and a second pad is provided between the pad and the first support frame.

[0011] The technical solution is further configured such that the cylinder is connected to the protective cover, a bushing is provided between the motor and the cylinder, and a third gasket is provided between the end of the bushing and the fixed end of the motor. The technical solution is further configured such that a wear-resistant ring is provided at the connection between the cylinder and the roller.

[0012] The beneficial effects of this utility model are: 1. By integrating the motor and reducer inside the drum, the horizontal and vertical space occupied by the equipment is greatly reduced, which improves the layout flexibility of other functional modules and the overall space utilization of the open-pit continuous coal mining machine.

[0013] 2. The first support frame and the second support frame form an arched structure, eliminating the need to design and install special support devices, bearings and other components for the crusher on the continuous coal mining machine. This simplifies the overall structure of the crusher, facilitates its disassembly and maintenance, and reduces maintenance costs and time.

[0014] 3. The protective cover design effectively prevents coal fragments from flying around during crushing, protecting the crusher from damage and ensuring the safety of operators. Simultaneously, the external spray nozzles provide dust suppression during operation, improving the working environment and further enhancing operational safety and equipment stability.

[0015] 4. It can be leveled and adjusted in multiple directions to adapt to the crushing needs of coal blocks of different sizes and thicknesses, making the equipment more adaptable and flexible, and able to maintain efficient operation under different working conditions.

The outer periphery of the motor 11 is provided with a cylinder 2, and the cylinder 2 is provided with an external spray nozzle. The cylinder 2 and the roller 1 can rotate relative to each other.

[0021] Understandably, by integrating the motor 11 and reducer 12 into the drum 1, the horizontal and vertical space occupied by the equipment is greatly reduced, and the layout flexibility of other functional modules and the overall space utilization of the open-pit continuous coal mining machine are improved.

[0022] In this embodiment, for a crushing device used in an open-pit continuous coal mining machine, please refer to... Figures 1 to 5The power output end of the reducer 12 is connected to the support shaft 14 via the drive disk 13. The drive disk 13 is connected to the roller 1. The support shaft 14 is rotatably mounted on the first support frame 4.

[0023] Specifically, the power output end of the motor 11 is connected to the reducer 12, the power output end of the reducer 12 is connected to the drive disk 13, and the drive disk 13 is connected to the support shaft 14. The support shaft 14 is rotatably mounted on the first support frame 4 and is sealed with an end cover.

[0024] It is understandable that the motor 11 will drive the reducer 12 to operate, thereby driving the drive disc 13 and the drum 1 to operate. Finally, the cutting teeth 6 installed on the outer surface of the drum 1 will crush the coal blocks below the crusher. The external spray nozzle will spray mist water droplets to remove dust, improve the working environment, and further enhance the operational safety and stability of the equipment.

[0025] In this embodiment, for a crushing device used in an open-pit continuous coal mining machine, please refer to... Figures 1 to 5 The motor 11 is mounted on the second support frame 5, which is positioned opposite to the first support frame 4, and a protective cover 3 is provided between them.

[0026] Specifically, the protective cover 3 is designed in an arc shape, which can effectively prevent coal fragments from flying around during crushing operations, protect the crusher from damage, and ensure the safety of operators.

[0027] Furthermore, the first support frame 4 and the second support frame 5 are respectively connected to the body of the continuous coal mining machine. The first support frame 4 and the second support frame 5 are provided with multiple mounting holes along the vertical direction.
