The lines coincide with each other, an arc-shaped opening 204 is provided in the middle of the discharge hole 202, an arc-shaped sealing plate 205 is slidably connected to the middle of the arc-shaped opening 204, a circular hole is provided in the middle of the arc-shaped sealing plate 205, and the diameter of the circular hole is consistent with the diameter of the discharge hole 202, a guide groove 206 is provided on the bottom surface of the arc-shaped sealing plate 205, a toggle plate 207 is fixedly connected to the bottom end of the arc-shaped sealing plate 205, and the inner sliding connection of the guide groove 206 There is a guide block 208, one end of the arc-shaped blocking plate 205 away from the toggle plate 207 is fixedly connected with a spring 209, the other end of the spring 209 is connected to the gantry 401 through a fixed block, the end of the arc-shaped blocking plate 205 close to the spring 209 is fitted with a limit rod 2010, the limit rod 2010 and the guide block 208 are fixedly connected to the top surface of the gantry 401, and a blocking plate 2011 is provided on the front side of the gantry 401, the inner arc surface of the toggle plate 207 is fitted with a toggle block 2012, two torsion springs 2013 are provided on both sides of the bottom of the toggle block 2012, the two torsion springs 2013 are respectively fixedly connected to one side of two mounting plates 2014, the two mounting plates 2014 are fixedly connected to the top surface of the moon-shaped plate 2015, the moon-shaped plate 2015 is welded to one side of the planetary frame 405, and the top surface height of the toggle block 2012 is lower than the bottom surface height of the top plate of the gantry 401;When the planet carrier 405 rotates, the feed tube 203 and the moon plate 2015 connected thereto will also rotate together, and the circumferential distance between the feed tube 203 and the moon plate 2015 is equal to the circumferential distance between the circular hole in the middle of the arc-shaped blocking plate 205 and the toggle plate 207. Therefore, when the feed tube 203 rotates with the planet carrier 405 to the bottom of the feeding cylinder 201, the toggle block 2012 just toggle the toggle plate 207 to contact with the blocking plate 2011, and the toggle plate 207 also drives The arc-shaped plugging plate 205 moves. During the movement of the arc-shaped plugging plate 205, the guide groove 206 at the bottom thereof will perform an arc-shaped motion under the action of the guide block 208, that is, the arc-shaped plugging plate 205 performs a circular motion in the direction of the central axis of the planetary frame 405.

[0031] The use method and advantages of the utility model: When the underground integrated sewage treatment equipment is in use, the working process is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, first, the sewage is discharged into the oxidation tank 3 from the water inlet pipe 5, and then the motor 402 is started to drive the planetary gear set to rotate, thereby driving the three groups of stirring rods 408 below to rotate and revolve at the same time, stirring the sewage in the oxidation tank 3, accelerating the mixing speed of the sewage and the treatment agent, and improving the treatment efficiency of the sewage. When the three planetary gears 404 revolve around the ring gear 406, they will also drive the planetary frame 405 connected thereto to rotate with the bearing sleeve 407 as the axis. When the planetary frame 405 rotates, the feed pipe 203 and the moon-shaped plate 2015 connected thereto will also rotate together. When the feed pipe 203 rotates to the bottom of the feeding tube 201, the arc-shaped sealing plate 205 will also drive the circular hole to move to the bottom of the feeding tube 201 under the action of the toggle block 2012, so that the feeding tube 201, the circular hole and the feed pipe 203 are connected, and the sewage treatment agent in the feeding tube 201 can smoothly fall into the hollow designed stirring rod. The liquid is then discharged from the agitator 408 through the hole 409 on the outer wall of the agitator 408 into the oxidation tank 3 to react with the sewage. The planetary frame 405 then continues to rotate. Since the toggle plate 207 is now in contact with the blocking plate 2011, the toggle block 2012 causes the planetary frame 405 to continue to rotate, causing the torsion spring 2013 to deform, causing the toggle block 2012 to rotate around the torsion spring 2013 and eventually disengage from the toggle plate 207. Then, under the action of the spring 209, the arc-shaped plugging plate 205 is reset, causing the circular hole on the arc-shaped plugging plate 205 to be misaligned with the feeding tube 201, and restoring the plugging state of the feeding tube 201, so that the treatment agent can be added to the feeding tube 201 again. During the whole process, the volume of the feeding tube 201 remains unchanged, which can ensure that the dosage of the treatment agent added each time is the same, and is convenient for adding a corresponding amount of sewage treatment agent according to the amount of sewage in the oxidation tank 3 to prevent waste or inadequate sewage treatment.
