As the air becomes more and more, piston shaft four passes over the connection between tube three and cylinder three. Subsequently, the air enters tube five through tube three, and is blown out to the surface of the salvage net through the blowing head on tube five, thereby blowing lighter debris such as leaves contaminated with water on the surface of the salvage net into the collection part to prevent them from sticking to the outer surface of the salvage net.

[0018] When some longer debris enters the inner cavity of the collecting part, it will squeeze the trigger part to move toward the outer shell, and the round rod will first move along the horizontal groove one. Then, when the horizontal groove one is located at the vertical groove, the elastic force of the spring four drives the round rod on the blocking part two to rise into the horizontal groove two. At this time, the debris has fallen on the surface of the conveying unit, and the blocking part two rises, so that the air in the inner cavity of the cylinder three is squeezed by the piston shaft four and enters the position of the piston cylinder two near the cylinder three along the tube four, and the blocking part one rises, and the air in the inner cavity of the piston cylinder two near the collecting part is discharged, and then the high-pressure gas squeezed by the piston shaft four and the elastic force of the spring one drive the chopping part to chop the longer debris on the conveying unit, thereby realizing the processing of the longer debris and avoiding the situation where its volume is large and affects the transportation efficiency.

[0037] The rotating disk 7 is connected with the sprocket 3 .

[0038] A limiting ring is arranged on the frame body 1, and the piston shaft 10 is sleeved in the limiting ring.

[0039] The air inlet portion 12 is composed of an air inlet pipe and a one-way air inlet valve, and the air outlet portion 13 is composed of an air outlet pipe and a one-way air outlet valve. The air outlet portion 13 is connected to one end of the piston cylinder 15 close to the collecting portion 14.

[0040] Embodiment three, as Figure 1-Figure 5 As shown, the sewage treatment equipment for river ecological restoration proposed by the present invention, compared with the second embodiment, the blowing mechanism of this embodiment includes a third pipe 31, a fifth pipe 47 and a blowing head 48; Pipe three 31 is connected to cylinder three 28, pipe five 47 is connected to pipe three 31 and is located in the salvage mechanism, and the blowing head 48 is connected to pipe five 47.

[0041] The pipe 5 47 is located inside the salvage net 5 , and the air blowing head 48 is directed toward the top of the collecting portion 14 .

[0042] The elastic member 1 33 and the elastic member 2 40 are both composed of a telescopic rod and a spring 5.

[0043] In summary, in the present invention, the frame 1 is installed in the river channel, and the collecting part 14 is located above the water surface, or the frame 1 is installed on a ship hull, and the frame 1 is driven by the ship hull to move in the river channel to salvage debris in the river channel.

[0044] The bottom of the frame 1 is located in the water, and then the driving device 2 is started to drive the sprocket 3 to rotate, and the rotation of the sprocket 3 drives the chain 4 to operate, and then the operation of the chain 4 drives the salvage net 5 to operate, so as to transport the floating debris in the water to the inner cavity of the collection part 14, and then the smaller debris passes through the trigger part 35 and falls on the conveying unit 49 and is transported to the storage space.

[0045] When the sprocket 3 rotates, it drives the turntable 7 to rotate, and drives the piston shaft 10 at the bottom end of the sleeve rod 9 to move along the axial direction of the piston cylinder 11 through the limit column 8 on the turntable 7. When the inner cavity of the piston cylinder 11 rises, the piston shaft 10 draws external air into the inner cavity of the piston cylinder 11 through the air inlet 12. When the piston shaft 10 descends in the inner cavity of the piston cylinder 11, the air in the inner cavity of the piston cylinder 11 is transported from the air outlet 13 to the side of the inner cavity of all piston cylinders 15 close to the collecting portion 14, thereby pushing the piston shaft 2 17 to move in the direction of the cylinder 3 28, so that the spring 16 is stretched.

[0046] When there is more air in the inner cavity of piston cylinder 215, high-pressure air enters the inner cavity of cylinder 23 along tube 11 and L tube 22, thereby driving piston shaft 3 25 to descend. At this time, the elasticity of spring 24 and the resistance of resistance ring 26 to piston shaft 3 25 make only high-pressure gas push open. When piston shaft 3 25 descends and passes over tube 27, air enters the inner cavity of cylinder 3 28 along tube 27. At this time, the elasticity of spring 3 29 drives piston shaft 4 30 to compress the air entering the inner cavity of cylinder 3 28. When piston shaft 4 30 passes over the connection between tube 3 31 and cylinder 3 28, air will enter tube 5 47 along tube 3 31, and then be blown out to salvage net 5 through blowing head 48, thereby blowing debris such as leaves on salvage net 5 to the inner cavity of collecting part 14, thereby preventing these debris from being contaminated on the surface of salvage net 5.

[0047] When some longer debris enters the collecting portion 14, the trigger portion 35 is pushed to move toward the inner cavity of the shell 32. At this time, the round rod 46 moves relatively along the horizontal groove 1 36. When it is located at the vertical groove 37, the elasticity of the spring four 44 drives the round rod 46 to enter the horizontal groove 2 38.

[0048] Then the longer debris falls on the conveying unit 49, and at the same time the blocking portion 25 moves upward, allowing the tube 42 to pass through. The elasticity of the spring 3 29 drives the piston shaft 4 30 to convey the air in the inner cavity of the cylinder 3 28 along the tube 4 42 to the inner cavity of the piston cylinder 2 15 on the side close to the cylinder 3 28. At the same time, the blocking portion 1 21 rises, allowing the air in the inner cavity of the piston cylinder 2 15 on the side close to the collecting portion 14 to be discharged from the exhaust hole of the cylinder 20.

[0049] The high pressure air that subsequently enters the inner cavity of the piston cylinder 15 and the elasticity of the spring 16 drive the chopping portion 18 to chop the longer debris into several sections.

[0050] The trigger part 35 is reset by the elastic drive of the elastic member 1 33, and the round rod 46 moves from the horizontal groove 2 38 to the inclined groove 39, and after squeezing the blocking part 41 into the elastic member 2 40, returns to the horizontal groove 1 36, so that the round rod 46 descends, thereby driving the blocking part 2 45 and the blocking part 1 21 to descend, and the air on the side of the piston cylinder 2 15 close to the cylinder 3 28 is slowly discharged, and then the air entering the inner cavity of the piston cylinder 2 15 close to the collecting part 14 drives the piston shaft 2 17 to reset, thereby driving the chopping part 18 to reset.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
