[0030] Specifically, as Figure 2 Indicated, oil discharge mechanism 2 includes connecting pipe 201, electromagnetic valve 202 and pump body 203, the left side of connecting pipe 201 is fixedly communicated with the right side of electromagnetic valve 202, and the left side of electromagnetic valve 202 is fixedly communicated with the right side of pump body 203.

[0031] Specifically, as Figure 2As shown, the left side of the pump body 203 is fixedly connected with the conveying pipe 4, and the bottom of the conveying pipe 4 is fixedly connected with the top of the discharge box 3.

[0032] Specifically, as shown in Figure 2 and Figure 6 , the left side of the discharge box 3 is fixedly connected with the discharge nozzle 5, the left side of the discharge nozzle 5 is fixedly connected with the discharge port 6, and the left side of the discharge port 6 is fixedly connected with the discharge pipe 14.

[0033] In this embodiment: by connecting the electromagnetic valve 202 and the pump body 203 with the control terminal through Ethernet, the operator can remotely control the electromagnetic valve 202 and the pump body 203, open the electromagnetic valve 202 and control the pump body 203 to work, so that the hydraulic oil in the body 1 can be pumped out and delivered to the inside of the discharge box 3 through the conveying pipe 4, facilitating timely replacement of the hydraulic oil in the body 1.

[0034] Specifically, as shown in Figure 6 , the surface of the discharge pipe 14 is fixedly provided with anti-skid rings 12, and the anti-skid rings 12 are evenly distributed on the surface of the discharge pipe 14.

[0035] Specifically, as shown in Figure 2 , Figure 3 and Figure 5 , the two sides of the discharge box 3 are fixedly connected with limiting frames 10, the top of the limiting frame 10 is provided with a limiting pin 13, the plug-in block 904 is movably inserted into the limiting frame 10, and the bottom of the limiting pin 13 extends into the plug-in block 904.

[0036] In this embodiment: the anti-skid rings 12 on the surface of the discharge pipe 14 can increase the friction force of the operator when connecting the external extension pipe, facilitating operation, the filter box 901 is installed by cooperating with the limiting frames 10 on both sides of the discharge box 3 through the plug-in block 904, the plug-in block 904 is movably inserted into the limiting frame 10, and is fixed by the limiting pin 13, so that the filter box 901 will not be displaced during work, and the filter box 901 can be easily pulled out from the inside of the discharge box 3 for cleaning.

[0037] Specifically, as shown in Figure 2 and Figure 3 , the front side of the discharge box 3 is fixedly connected with a sealing gasket 11, and the rear side of the filter box 901 is in close contact with the front side of the sealing gasket 11.

[0038] Specifically, as shown in Figure 2 and Figure 4 , the inside of the filter box 901 is provided with an L-shaped pipe 8, the front side of the L-shaped pipe 8 extends to the outside of the discharge box 3 through the discharge box 3, and the four corners of the bottom of the discharge box 3 are fixedly connected with supporting legs 7.

[0039] In the embodiment, the sealing gasket 11 on the front side of the discharge tank 3 is in close contact with the rear side of the filter box 901, which ensures the sealing of the discharge tank 3 and prevents hydraulic oil from leaking from the gap between the filter box 901 and the discharge tank 3. By connecting the inlet and outlet of the U-shaped pipe 8 with the external circulating refrigeration device, the external refrigeration device can deliver low-temperature coolant into the U-shaped pipe 8, thereby cooling the discharged hydraulic oil.

[0040] Working principle: when the hydraulic machine completes the work task and needs to discharge and replace the hydraulic oil, the operator can issue the oil discharge instruction at the external control end, so that the electromagnetic valve 202 is opened, and the pump body 203 starts to operate to pump out the used hydraulic oil. The hydraulic oil pumped out by the pump body 203 is transported to the discharge tank 3 through the conveying pipe 4. The conveying pipe 4 connects the pump body 203 and the discharge tank 3 to form a closed conveying channel, which ensures that the hydraulic oil can flow smoothly from the pump body 203 to the discharge tank 3 and prevents oil leakage. During the entire oil discharge process, the connecting pipe 201, the electromagnetic valve 202, the pump body 203 and the conveying pipe 4 work together to realize the automatic transfer of the hydraulic oil from the hydraulic machine body 1 to the discharge tank 3, without the need for manual use of the external oil pump for pumping, which improves the oil discharge efficiency and convenience. The filter mechanism 9 mainly consists of a filter box 901, a filter screen 902, a handle 903 and an insertion block 904. The filter box 901 is movably inserted into the discharge tank 3, and the filter screen 902 is fixed to the inner wall bottom of the filter box 901. When the hydraulic oil enters the discharge tank 3, it first passes through the filter screen 902, which can effectively filter out impurities such as metal chips, dust particles and gum in the hydraulic oil. These impurities are blocked by the filter screen 902 and remain in the filter box 901, while the filtered clean hydraulic oil continues to flow in the discharge tank 3. For example, after long-term use of the hydraulic oil, it may contain a large amount of impurities. Through the filtering action of the filter screen 902, the discharged hydraulic oil can reach a certain degree of cleanliness, which is beneficial to the subsequent recycling of the hydraulic oil. The filter box 901 is installed on both sides of the discharge tank 3 through the insertion block 904 and the limiting frame 10. The insertion block 904 is movably inserted into the limiting frame 10 and is fixed by the limiting pin 13 to ensure that the filter box 901 does not shift during operation. The sealing gasket 11 on the front side of the discharge tank 3 tightly contacts the rear side of the filter box 901 to ensure the sealing of the discharge tank 3 and prevent the hydraulic oil from leaking between the filter box 901 and the discharge tank 3. When the filter screen 902 needs to be cleaned, the operator can pull out the filter box 901 from the discharge tank 3 through the handle 903, which is convenient and fast. The discharge tank 3 serves as a temporary storage and transfer container for the hydraulic oil and plays an important role in the entire oil discharge process. The hydraulic oil enters the discharge tank 3 through the pump body 203 and the conveying pipe 4, is filtered and temporarily stored in the discharge tank 3, and is discharged to a designated location such as a recycling container or a treatment device through the discharge nozzle 5, the discharge port 6 and the discharge pipe 14 on the left side of the discharge tank 3. The anti-slip ring 12 on the surface of the discharge pipe 14 can increase the friction force of the operator when connecting the external extension pipe, making it easier to operate. The supporting legs 7 at the bottom of the discharge tank 3 are used to support the discharge tank 3 and keep it in a stable position. By connecting the inlet and outlet of the coiled tube 8 to the external circulating refrigeration equipment, the external refrigeration equipment can deliver low-temperature coolant to the inside of the coiled tube 8, which can cool the discharged hydraulic oil. This avoids the need for the operator to open the hydraulic machine oil tank and use an external oil pump to pump out the hydraulic oil for timely replacement,And the impurities in the hydraulic oil are not filtered during the hydraulic oil discharging process, which affects the recycling and quick discharging and replacing of the hydraulic oil, and affects the quick use of the hydraulic machine again.

[0041] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
