Description

Technical Field

[0001] The invention belongs to the technical field of coal crushing equipment and relates to a hydraulically driven wheel crusher. Background Art

[0002] A wheeled crusher is a crushing machine that cuts through the rotating motion of its hammer head. It is installed on the chute loader of the fully mechanized mining face in underground coal mines. It can crush large pieces of coal and gangue, reducing the difficulty and cost of transportation, ensuring transportation safety, and improving work efficiency. It is a common transportation equipment in modern coal mines.

[0003] At present, the commonly used transmission method of underground coal mine crushers is electronic control transmission. The motor drives the small pulley, and the small pulley drives the large pulley to rotate through the belt. The large pulley drives the hammer head to rotate through the crushing shaft to crush large pieces of coal and gangue. The soft connection such as the belt can effectively reduce the impact force and avoid damage to the crushing shaft.

[0004] However, due to the changeable geological environment underground, for production needs, it is sometimes necessary to pick the top and bottom and cut out a large amount of gangue. If the hard gangue is crushed for a long time, on the one hand, the high load may cause the belt to deform when transmitting torque, resulting in reduced transmission efficiency and increased energy consumption. On the other hand, if the equipment itself has dynamic balance problems, the soft connection may easily amplify the vibration, causing the vibration to be transmitted to the motor, causing damage to the motor and increasing maintenance costs.

[0029] Working principle: When in use, the hydraulic pump 10 is turned on, and the hydraulic pump 10 uses the first oil inlet pipe 21 to extract the hydraulic oil in the oil tank 17.

The hydraulic motor 5 drives the hammer head 29 to reverse through the hydraulic coupling 3 and the reducer 2 to crush the gangue. When returning the oil, the hydraulic oil in the hydraulic motor 5 returns to the return oil distributor 14 through the first return oil pipe 26, and is filtered again through the return oil filter 16 connected to the return oil distributor 14, and finally returns to the oil tank 17 for circulation. The oil pressure intelligent display 18 supports the pressure display of the hydraulic oil and intelligent calculation of the oil pressure required for the return oil, so that the hydraulic motor 5 runs smoothly.

[0030] When encountering large rocks that need to be initially crushed by the hydraulic pick 6, the pressurized hydraulic oil enters the hydraulic centralized control system 7 through the fifth oil inlet pipe 25 to control the hydraulic pick, and the return oil flows back to the oil tank 17 through the second oil return pipe 27.
