The larger end of the waste frame 3 faces the direction where the output nozzle 23 is located, and a square base 32 is provided at the bottom of the waste frame 3. The base 32 is erected above the base 32 through four support rods 31. The four support rods 31 are respectively fixedly connected to the four top corners of the top of the waste frame 3. A connecting spring 33 is provided between each support rod 31 and the base 32. One end of the connecting spring 33 is fixedly connected to the base 32, and the other end is fixedly connected to the support rod 31.

[0026] See also Figure 1-2 As shown, the bottom of the waste frame 3 is connected with a conveying pipe 4, and the conveying pipe 4 passes through the machine body 1 through the removal port 11. The horizontal height of the end of the conveying pipe 4 connected to the waste frame 3 is higher than the horizontal height of the other end. The conveying pipe 4 is divided into a conveying hard pipe 41, one end of the conveying hard pipe 41 is connected to the waste frame 3, and the other end is connected to a conveying hose 42 made of a corrugated pipe.

[0027] A specific application of this embodiment is:

[0028] When the lathe is performing turning processing, the liquid supply pump 22 transports the coolant in the liquid supply tank 2 to the liquid supply pipe 21, and the coolant is transported to the output nozzle 23 through the cooling pipe. The coolant is sprayed from the output nozzle 23 to the position where the lathe is turning, and the waste chips generated by turning and the coolant dripping after the cooling work is completed fall into the waste frame 3 simultaneously.

[0029] When the waste chips and the coolant fall into the waste frame 3 at the same time, the vibration motor drives the waste frame 3 to shake, and the connecting spring 33 allows the waste frame 3 to shake. During the shaking of the waste frame 3, the waste chips and the coolant in the waste frame 3 shake at the same time, and the filter screen 34 blocks the waste chips. The coolant adhered to the waste chips enters the transport hard pipe 41, and the transport hard pipe 41 shakes synchronously with the waste frame 3, so that the coolant quickly passes through the transport hard pipe 41 and the transport hose 42. The transport hose 42 allows the transport hard pipe 41 to shake with the waste frame 3, and the coolant enters the cooling box 5 through the transport pipe 4. The coolant dissipates heat in the cooling box 5 by natural heat dissipation to ensure the use effect of the coolant. When the coolant level in the cooling box 5 is above the end of the output pipe 512, the coolant in the cooling box 5 enters the output pipe 512 through the extraction action of the output pump 511, and finally enters the liquid supply tank 2 through the output pipe 512 to complete the recovery. In summary, through the above steps, the effect of recycling the coolant is achieved. At the same time, the coolant can be used in the next coolant supply process, realizing the reuse of the coolant, improving the reuse of resources, and improving the environmental protection of the equipment.
