Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a sludge cleaning device for soil and water environment improvement, including a pump body. As Figure 5 shown, the pump body includes a pump housing 8. An impeller 20 is provided inside the pump housing. An output pipe 7 is provided on the side surface of the pump housing 8. The output pipe 7 is used to discharge sludge outward. In the actual operation process, a conveying pipeline is connected to the output pipe 7.

[0031] It further includes a driving device for driving the pump body to rotate. The driving device includes a support pipe body 6. A support disc 3 is provided at one end of the support pipe body 6. A driving shaft 19 is movably provided inside the support pipe body 6. The two ends of the support pipe body 6 are respectively rotationally connected to the driving shaft 19. In this way, the driving shaft 19 can rotate stably inside the support pipe body 6;

[0032] One end of the drive shaft 19 close to the support disk 3 extends outside the support tube body 6 and is connected to the drive motor 1. The edge of the support disk 3 is connected to the drive motor 1 through a plurality of connecting support feet 2. An end cover 18 is provided at one end of the support tube body 6 away from the support disk 3. The edge of the end cover 18 is connected to the pump housing 8 by bolts, which facilitates the disassembly and installation of the pump housing.

[0033] Among them, the drive shaft 19 extends into the pump housing 8, and the impeller 20 is installed on the drive shaft 19. Specifically, during the operation process, when the drive motor 1 rotates, it can drive the drive shaft 19 to rotate inside the support tube body 6, causing the drive shaft 19 to drive the impeller 20 to rotate rapidly.

[0034] As Figure 3 and Figure 5 shown, one side of the pump housing 8 away from the support disk 3 is installed at the lower middle part of the side of the crushing box 9, and the pump housing 8 is flush with the bottom of the crushing box 9. An inlet 21 communicating with the inside of the pump housing 8 is provided at the bottom of the side of the crushing box 9. The provided crushing box 9 can increase the opening size of the inlet 21. During the cleaning process of the silt, when the silt gathers towards the pump body, the silt will first enter the crushing box 9 and then enter the pump housing 8 through the inlet 21.

[0035] Two parallel mounting shafts 15 are provided inside the crushing box 9. Both ends of the mounting shafts 15 are rotatably connected to the side walls of the crushing box 9. Multiple groups of crushing blades 16 are installed on the surfaces of the mounting shafts 15. As Figure 4 shown, the crushing blades 16 on the two mounting shafts 15 are arranged staggeredly. When the mounting shafts 15 rotate, they can drive the crushing blades 16 to cross-shear, so that the sundries entering the crushing box 9 are quickly crushed; the crushing blades 16 are all connected to the tool holders by bolts, and the tool holders are welded and fixed on the surfaces of the mounting shafts 15, which facilitates the disassembly and replacement of the crushing blades.

[0036] As Figure 1 shown, transmission gears 10 are respectively installed at one ends of the two mounting shafts 15, and the two transmission gears 10 are meshed with each other. A transmission shaft 12 is vertically provided at the end of one of the mounting shafts 15. Bevel gears 11 are provided at the opposite ends of the mounting shaft 15 and the transmission shaft 12, and the two bevel gears 11 are meshed with each other.

[0037] As Figure 1 and Figure 2 、 Figure 3 shown, the transmission shaft 12 is parallel to the support tube body 6. At least two bearing seats 13 are rotatably installed on the transmission shaft 12. Each bearing seat 13 is connected to the support tube body 6 through a support arm 4. The bearing seats 13 are distributed at both ends and the middle of the transmission shaft, so that the transmission shaft 12 can be kept stable when the transmission shaft 12 rotates. As Figure 1As shown in the figure, a connecting seat 5 corresponding to the support arm 4 is provided on the support tube body 6, and the support arm 4 is fastened to the connecting seat 5 by bolts.

[0038] One end of the transmission shaft 12 away from the crushing box 9 is connected to the driving device through a transmission mechanism. The driving device drives the transmission shaft 12 to rotate through the transmission mechanism. That is, the transmission mechanism includes pulleys 14 arranged at one ends of the transmission shaft 12 and the driving shaft 19 close to the driving motor 1, and the two pulleys 14 are connected by a belt. Of course, the pulley 14 can be replaced by a synchronous pulley and a sprocket. When the pulley 14 is replaced by a synchronous pulley, the two synchronous pulleys are connected by a synchronous belt. When the pulley 14 is replaced by a sprocket, the two sprockets are connected by a transmission chain. Therefore, when the driving motor 1 drives the impeller to rotate, the driving motor 1 can also drive the transmission shaft 12 to rotate through the transmission mechanism, causing the transmission shaft 12 to drive the two bevel gears 11 to rotate, and the bevel gears 11 to drive the two mounting shafts 15 to rotate. While the impeller rotates, the mounting shafts 15 rotate accordingly for crushing.

[0039] As Figure 1 shown, the mounting shaft 15 is horizontally arranged inside the crushing box 9, and the crushing blades fill the entire crushing box 9, which can accelerate the efficiency of crushing the sludge entering the crushing box 9, and the rotation directions of the crushing blades all face the inlet 21, so as to accelerate the flow of the sludge towards the inlet direction.

[0040] In order to prevent foreign objects from directly contacting the gears, further, a sealing housing 17 is provided at one end of the crushing box 9 close to the transmission gear 10. The edge of the sealing housing 17 is connected to the side surface of the crushing box 9 by bolts, and the transmission shaft 12 passes through the side surface of the crushing box 9 and is rotatably connected therebetween. By covering each gear with the sealing housing 17, it is possible to prevent the sludge from contacting the gears. Lubricating fluid can be contained in the sealing housing 17 to prevent dry grinding between the gears.

[0041] Further, this solution also includes a carrier of the sludge cleaning device. The carrier includes two symmetrically arranged floating valves 23, which are connected by a plurality of brackets 22. The support tube body 6 is fixed in the middle of the brackets 22, and the support tube body 6 is inclined, so that the driving motor 1 is located above the floating valves 23, and the crushing box 9 is located at the bottom between the two floating valves 23. The floating valves 23, as the carrier of the pump body and the driving device, can float on the surface of the sludge to prevent the pump body from sinking.

[0042] In summary, when the present utility model is in use, the floating valves 23 are placed in the dredging area. Operators can use tools such as water guns or machinery such as excavators to push the sludge towards the crushing box 9. The sludge and sundries entering the crushing box 9 will be crushed by the rapidly rotating crushing blades 16 and then enter the pump housing through the inlet 21, and finally be output outward through the output pipe 7.

[0043] When the driving motor 1 rotates, it can drive the crushing blade 16 and the impeller to rotate simultaneously, enabling the impeller and the crushing blade to share a driving motor. Moreover, the horizontally arranged crushing blade 16 has a wide crushing range and can also accelerate the flow of sludge into the pump casing, thereby accelerating the efficiency of sucking sludge.
