[0010] Furthermore, the second rotating rod is fixedly mounted at one end of the auger.

[0011] Furthermore, the second bevel gear is fixedly disposed at one end of the first rotating rod, and the first rotating rod is rotatably disposed inside the housing.

[0012] Furthermore, the first bevel gear and the second bevel gear mesh with each other.

[0013] Furthermore, the filtration mechanism includes a support cylinder, on the bottom side of which a second filter screen is fixedly disposed, and the support cylinder is fixedly disposed inside the cylinder body.

[0014] Furthermore, the drive mechanism includes a motor and two support rods, the output end of the motor is connected to a connecting rod, and the support rods are connected to the cylinder.

[0015] Furthermore, a support ring is fixedly installed on the outside of the motor, and the support rod is fixedly installed on the outside of the support ring.

[0016] With the above structure, when using this device, firstly, wastewater enters the device, then the second filter screen on the filtration mechanism filters the waste. Then, the motor drives the scraper through the connecting rod to scrape and push the waste on the second filter screen. Next, the waste enters the tube of the discharge mechanism through the guide plate. At the same time, the connecting rod drives the bevel gear to drive the universal joint to rotate, and then the universal joint drives the auger to rotate. Then, some of the wastewater in the waste is filtered out through the first filter screen, and then the waste is moved out of the device through the auger.
