The plurality of oil injection cylinders 2 are used for accommodating lubricating substances such as lubricating oil required by various mining equipment. The oil injection cylinders 2 are in one-to-one correspondence with oil injection points or oil injection holes of the mining equipment, and the oil outlet pipelines 6 corresponding to the oil injection cylinders 2 are used for discharging substances such as lubricating oil and the like and are simultaneously used for injecting the substances into the corresponding oil injection points or oil injection holes to lubricate corresponding parts of the mining equipment.
In this embodiment, the oil inlet pipe 9 is used to supplement the oil cylinder 2 with substances such as lubricating oil. After the piston 3 drives the piston 3 to move through a piston 3 rod, the piston 3 can be pressed down to squeeze lubricating oil for the oil outlet pipeline 6, so that the lubricating oil is discharged along the oil outlet pipeline 6.

By screwing the rod of the piston 3 to the housing 13 and the worm wheel 11, the worm wheel 11 can be rotated to linearly move the rod of the piston 3 along the axial direction thereof, thereby driving the corresponding piston 3 to move. The worm 12 may be used to drive the worm gear 11 in rotation. The driving motor 14 is used for driving the worm 12 to rotate. Thus, the drive motor 14 can effectively drive the worm 12 to rotate.

In some implementations of this embodiment, the piston 3 rod includes a first rod 401 and a second rod 402 that are coaxially disposed, where the first rod 401 is connected to the piston 3, and a rotating assembly is disposed between the first rod 401 and the second rod 402. The rotating assembly is used for realizing the relative rotation of the first rod body 401 and the second rod body 402. Thus, when the first rod 401 drives the piston 3 to move, the piston 3 can be rotated, and the sealing effect of the piston 3 is prevented from being affected.

When the driving mechanism drives the second rod 402 to lift, if the second rod 402 rotates, the rotation can be eliminated at the bearing 15, so that the second rod 402 does not drive the first rod 401 to rotate, and the piston 3 is not driven to rotate. In this way, the movement of the first rod 401 and the second rod 402 in the axial direction is not affected.
In some embodiments of the present embodiment, the free end of any one of the oil feed lines 9 is connected to a lubricant storage tank 17. The lubricating oil storage tank 17 can store similar lubricating substances and provide a source of lubricating substances for the oil feed line 9.

The oil inlet pipelines 9 share the same lubricating oil storage tank 17, and the occupied space can be reduced in a shared mode on the premise that the corresponding oil inlet pipelines 9 adopt the same lubricating substance.
In some implementations of the present embodiment, a second oil amount sensor is disposed in the lubricating oil storage tank 17, and the second oil amount sensor is connected to the control unit. The second oil quantity sensor is used for detecting the content of substances in the lubricating oil storage tank 17, transmitting detected information to the control unit, and analyzing and judging whether the lubricating substances need to be added or not by the control unit.
The first oil mass sensor and the second oil mass sensor are liquid level sensors.
In some implementations of this embodiment, the control unit is connected with an early warning device. The early warning device can play a role in early warning, and the control unit can control the early warning device to give an alarm to remind the user of adding the corresponding lubricating substances after judging that the content of the substances in the lubricating oil storage tank 17 is lower than the rated value.
When the mining equipment is used, the plurality of monitors are respectively used for being arranged at each oil injection point of the mining equipment and used for detecting the state of lubricating oil at parts of the oil injection point.

The tail end of each oil outlet pipeline 6 is correspondingly connected to an oil injection point or an oil injection hole of each corresponding lubricating substance of the equipment. After judging that the corresponding oil injection point needs to be injected with new lubricating oil, the control unit can control the corresponding driving mechanism to act, so that the piston 3 rod is pressed down and then drives the piston 3 to move downwards, and the lubricating oil in the oil injection barrel 2 enters the oil outlet pipeline 6 to discharge the lubricating oil to the corresponding injection point.
The control unit may control the stroke of the piston 3, as required, whereby the amount of oil injected into the corresponding device may be controlled. The first check valve 7 is matched with the second check valve 10, so that when the piston 3 is pressed down, the pressure of lubricating oil in the oil injection cylinder 2 is increased, the first check valve 7 is opened, and the lubricating oil is discharged after entering the oil outlet pipeline 6 to inject oil into mining equipment. At this time, the second check valve 10 corresponds to disconnecting the oil feed line 9, and the lubricating oil is not discharged along the oil feed line 9. Conversely, after the injection of lubrication is continued, the piston 3 in the cylinder 2 reaches the stroke point, and the cylinder 2 is considered to be depleted of lubrication oil.
At this time, the rod of the controllable piston 3 drives the piston 3 to reset. In the process of resetting the piston 3, the interior of the oil injection barrel 2 is in a negative pressure environment, at the moment, the second one-way valve 10 is opened, and new substances such as lubricating oil and the like enter the oil injection barrel 2 along the oil inlet pipeline 9 to supplement the lubricating oil for the oil injection barrel 2. At this time, the first check valve 7 opens the oil outlet pipe 6, and the lubricating oil and the like are not discharged along the oil outlet pipe 6.
It should be noted that the control unit is an integrated circuit chip, and is a small and perfect microcomputer system formed by integrating functions (possibly including a display driving circuit, a pulse width modulation circuit, an analog multiplexer, an a/D converter and the like) such as a central processing unit CPU, a random access memory RAM, a read only memory ROM, various I/O ports and interrupt systems, a timer/counter and the like with a silicon chip by adopting a very large scale integrated circuit technology, and is widely applied in the field of industrial control. In this embodiment, a single-chip microcomputer is specifically selected as the control unit, and the single-chip microcomputer may be a 51-series single-chip microcomputer or an AVR-series single-chip microcomputer, and may be ATmega8/16/32/64/128 (storage capacity is 8/16/32/64/128 KB) or ATmega 8515/8535.
