The two ends of the reduction box 3 are respectively rotatably connected to a drive shaft 17 and an output shaft 4, and one end of the drive shaft 17 is fixedly connected to a first pulley 13. A transmission belt 15 is sleeved on the first pulley 13 and the second pulley 14, and transmission is performed between the first pulley 13 and the second pulley 14 through the transmission belt 15.

[0046] In the specific implementation, it should be noted that the reduction box 3 in the present invention is internally provided with a plurality of gears for transmission (not shown in the figure), and the gears are used to transmit the mechanical energy output by the motor 5 to the output shaft 4.

[0050] In a specific implementation, a check valve is provided at the connection point between the oil inlet pipe 10 and the reduction box 3 .

[0051] As a further embodiment of the present invention, the first oil groove 20 is located below the second oil groove 21 .

[0052] In a specific implementation, by providing the first interlayer 18 and the second interlayer 23 , the material consumption of the housing of the reduction gearbox 3 and the housing of the motor 5 can be effectively saved.

[0053] Working principle of the present invention:

[0054] When the present invention is in use, first, by turning on the motor 5, the motor 5 will drive the first pulley 13 to rotate. The first pulley 13 drives the second pulley 14 to effectively rotate through the transmission belt 15. After the second pulley 14 rotates, it will drive the drive shaft 17 to rotate. The drive shaft 17 then drives the output shaft 4 to rotate through the gears set inside the reduction box 3, so that the output shaft 4 can drive the oil pump to work.

[0055] As the motor 5 works, the wear of the gears and the lubricating oil in the reduction box 3 will generate a large amount of heat. The increase in the temperature of the lubricating oil will reduce its viscosity, which will easily lead to increased wear of the gears inside the reduction box 3. At the same time, the continuous increase in the temperature of the lubricating oil will also reduce the service life of the lubricating oil. Secondly, the increase in the temperature inside the reduction box 3 will also increase the internal pressure.

[0056] As the internal pressure of the reduction box 3 increases, when the pressure inside the reduction box 3 increases to the preset pressure value of the pressure relief valve 29, the pressure relief valve 29 opens. On the one hand, it can effectively relieve the pressure of the high-pressure environment inside the reduction box 3, which is beneficial to avoid the occurrence of excessive pressure inside the reduction box 3. On the other hand, after opening, the pressure relief valve 29 will relieve part of the lubricating oil inside the reduction box 3 into the second oil groove 21, and the groove 27 located at the bottom of the reduction box 3 can also collect metal debris generated by gear wear at the position of the pressure relief valve 29. With the opening of the pressure relief valve 29, the metal debris inside the reduction box 3 can be discharged in time; secondly, the reduction box 3 will vibrate during operation, and the use of vibration can also help to make the metal debris be shaken to the position of the pressure relief valve 29, further facilitating the pressure relief valve 29 to discharge the metal debris.

[0057] By setting the metal wear detection sensor 35, the metal debris inside the reduction box 3 can be effectively monitored in real time, and the magnetic head 36 at the end of the metal wear detection sensor 35 can also absorb some metal debris attached to the lubricating oil. While monitoring the metal debris in real time, it can also reduce the metal debris mixed in the lubricating oil to a certain extent, which is beneficial to avoid further aggravation of the internal gear wear due to the metal debris contained in the lubricating oil inside the reduction box 3.

[0058] The temperature inside the reduction box 3 is monitored in real time by the temperature sensor 19, which is beneficial to avoid the temperature inside the reduction box 3 being too high. When the temperature detected by the temperature sensor 19 is higher than the preset temperature value, the temperature sensor 19 will enable the second oil pump 8 to work through the controller. After the second oil pump 8 is started, it will extract lubricating oil from the first oil groove 20, and then transport it to the first interlayer 18 through the oil inlet pipe 10. Then the lubricating oil enters the first interlayer 18, and the original lubricating oil in the first interlayer 18 will be squeezed into the second interlayer 23 through the oil outlet pipe 11, and finally enter the connecting piece 25 through the return pipe 24. By utilizing the lubricating oil in the first oil groove 20, the reduction box 3 and the motor 5 can be effectively cooled through the first interlayer 18 and the second interlayer 23 respectively. On the one hand, it is beneficial to avoid the reduction box 3 from having an over-high temperature. On the other hand, it can also cool the motor 5, which is beneficial to avoid the motor 5 from being damaged due to overheating as the working time goes by.

[0059] The lubricating oil entering the second oil tank 21 through the pressure relief valve 29 will first be retained in the second oil tank 21, and the lubricating oil carried out of the lubricating oil will settle under the mounting frame 22. After the lubricating oil output by the second oil pump 8 enters the connecting piece 25, the oil pressure in the connecting piece 25 will increase. When the oil pressure in the connecting piece 25 increases to the preset pressure value of the pressure valve 26, the pressure valve 26 opens, so that the lubricating oil in the connecting piece 25 can enter the bottom of the second oil tank 21. The setting of the pressure valve 26 can increase the kinetic energy of the lubricating oil, so that the lubricating oil can enter the second oil tank 21. An impact is generated. When the second oil pump 8 is turned on, the electromagnetic plate valve 30 is opened at the same time. After the electromagnetic plate valve 30 is opened, the lubricating oil in the second oil tank 21 will flow to the first oil tank 20, and the lubricating oil in the first oil tank 20 will enter the second oil tank 21 through the pressure valve 26 after the reduction gearbox 3 and the motor 5 are cooled. The lubricating oil entering the second oil tank 21 will have an impact on the bottom of the second oil tank 21, so that the metal debris precipitated at the bottom of the second oil tank 21 can be effectively flushed into the storage box 7, and then the lubricating oil is filtered by the filter 32 and flows back to the first oil tank 20.

[0060] The circulation of lubricating oil in the first oil groove 20 and the second oil groove 21 can effectively dissipate heat and cool the reduction box 3 and the motor 5 on the one hand, and can also flush the metal debris deposited in the second oil groove 21 into the storage box 7 on the other hand, which is conducive to cleaning the metal debris and preventing the metal debris from mixing with the lubricating oil and flowing back into the reduction box 3. The setting of the check plate 34 can effectively press the lubricating oil entering the second oil groove 21 through the pressure valve 26 downward, which is conducive to preventing the metal debris deposited at the bottom of the second oil groove 21 from flowing back.

[0061] When the lubricating oil in the reduction box 3 enters the second oil tank 21 through the pressure relief valve 29, the amount of lubricating oil in the reduction box 3 will decrease, which will reduce the lubrication work of the lubricating oil on the gears. Therefore, after the pressure relief valve 29 is opened for a period of time, the first oil pump 6 is turned on. After the first oil pump 6 is turned on, the second oil pump 8 is closed. The first oil pump 6 will draw lubricating oil from the second oil tank 21 and then transport it to the reduction box 3 through the oil replenishing pipe 12. On the one hand, it can effectively replenish the lubricating oil in the reduction box 3. On the other hand, it can also utilize the impact of the lubricating oil from top to bottom to make the lubricating oil flush on the magnetic suction head 36, which is beneficial to flush the metal debris adsorbed on the magnetic suction head 36 to the bottom of the reduction box 3, so that it is convenient to discharge through the pressure relief valve 29.

[0062] During the operation of the reduction gearbox 3, the liquid level of the hydraulic oil in the reduction gearbox 3 can be penetrated through the transparent column 16, and the fan 9 is turned on during the operation of the reduction gearbox 3 to blow air to the transparent column 16 through the fan 9. On the one hand, the dust on the transparent column 16 can be blown off, which is beneficial to avoid the situation where the technicians cannot effectively observe the hydraulic oil level inside the reduction gearbox 3 due to dust on the transparent column 16. On the other hand, the air blowing of the fan 9 can also effectively dissipate the heat from the top of the reduction gearbox 3. Secondly, the wind blown by the fan 9 will blow on the wave plate 38 after passing through the transparent column 16, thereby causing the wave plate 38 to vibrate. After the wave plate 38 vibrates, it will drive the oil replenishing pipe 12 to vibrate effectively, which is beneficial to avoid the situation where dirt in the oil replenishing pipe 12 adheres to the inner wall of the oil replenishing pipe 12, thereby ensuring the effective transportation of lubricating oil by the oil replenishing pipe 12.

[0063] As the reduction gearbox 3 is used, the lubricating oil inside it will gradually age and produce an odor. Through the odor detection sensor 39 arranged on the top of the first oil tank 20, when the lubricating oil has an odor, it can be replaced in time based on the detection result of the odor detection sensor 39.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
