[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0023] Embodiment 1:

[0024] Please refer to Figures 1-5 , an embodiment of the present utility model is: A rapid dredging device for water conservancy projects with a stirring device, including a suction pipe 1, a suction head 5 is fixedly installed at the lower end of the suction pipe 1, and a stirring mechanism 2 is arranged on the suction pipe 1; the stirring mechanism 2 includes a mounting plate 201, a first bearing 204 and a second bearing 208, a motor 202 is fixedly installed at the bottom of the mounting plate 201, a gear 203 is fixedly installed at the output end of the motor 202, a tooth ring 206 is fixedly installed on the outer surface of the first bearing 204, a first fixing seat 205 is fixedly installed on the outer wall of the first bearing 204, the tooth ring 206 meshes with the gear 203, a rotating rod 207 is arranged on the first fixing seat 205, a stirring rod 211 is fixedly installed at the lower end of the rotating rod 207, a second fixing seat 209 is fixedly installed on the outer wall of the second bearing 208, and the rotating rod 207 passes through the second fixing seat 209. By adopting the above rapid dredging device, when it is necessary to pump the silt, the motor 202 is started to drive the first gear 203 to rotate, and the rotation of the gear 203 will drive the tooth ring 206 and the first fixing seat 205 to rotate, so that the rotating rod 207 makes a circular motion around the suction pipe 1. At this time, the stirring rod 211 will stir and crush the silt at the suction head 5, avoiding the problem that the suction port is blocked by large silt blocks, and improving the efficiency of dredging in water conservancy projects.

[0025] Furthermore, the suction pipe 1 is fixedly installed on the inner wall of the inner rings of the first bearing 204 and the second bearing 208, the mounting plate 201 is fixedly installed on the suction pipe 1, and a protective cover 4 is fixedly installed at the bottom of the mounting plate 201. The protective cover 4 can protect the motor 202, thereby extending the service life of the motor 202.

[0026] Further, an insertion hole is formed in the first fixing seat 205, the upper end of the rotating rod 207 is inserted into the insertion hole, a through hole 210 is formed in the second fixing seat 209, and the rotating rod 207 penetrates through the through hole 210. The setting of the first fixing seat 205 can limit and fix the upper end of the rotating rod 207, thereby ensuring the stability and reliability of its subsequent rotation.

[0027] By adopting the above-mentioned rapid silt cleaning device, its specific working principle is as follows:

[0028] The upper end of the pumping pipe 1 is externally connected to a sludge pump, and its suction head 5 extracts the sludge. At the same time, the motor 202 needs to be started to drive the first gear 203 to rotate. The rotation of the gear 203 drives the toothed ring 206 and the first fixing seat 205 to rotate, so that the rotating rod 207 makes a circular motion around the pumping pipe 1. At this time, the stirring rod 211 stirs and crushes the sludge at the suction head 5, avoiding the problem of blockage of the mud suction port caused by large sludge blocks, and improving the efficiency of silt cleaning in water conservancy projects.

[0029] Embodiment 2:

[0030] Please refer to Figures 1-5 , on the basis of the above embodiment, in another embodiment of the present utility model, a fixing mechanism 3 is provided on the second fixing seat 209. The fixing mechanism 3 includes a fixing frame 301 and a positioning column 302. A guiding hole is formed in the fixing frame 301, the positioning column 302 penetrates through the guiding hole, and a pulling head 303 is fixedly installed on the positioning column 302. The setting of the fixing mechanism 3 facilitates the installation and fixation of the rotating rod 207.

[0031] Further, a fixing plate 304 is fixedly installed on the positioning column 302, and a spring 305 is sleeved on the positioning column 302. The setting of the fixing plate 304 facilitates the spring 305 to push the positioning column 302.

[0032] Further, a positioning groove 306 is formed in the rotating rod 207, and one end of the positioning column 302 is inserted into the positioning groove 306. The cooperation between the positioning groove 306 and the positioning column 302 can position the rotating rod 207 on the second fixing seat 209.

[0033] By adopting the above-mentioned rapid silt cleaning device, its specific working process and principle are as follows:

[0034] When it is necessary to disassemble the rotating rod 207, the staff can pull the pulling head 303 in the direction away from the pumping pipe 1, so that the positioning column 302 disengages from the positioning groove 306 on the rotating rod 207. At this time, the rotating rod 207 can be withdrawn and disassembled from the first fixing seat 205 and the second fixing seat 209, which is convenient for quickly replacing the stirring rod 211, and also convenient for disassembling and transporting the silt cleaning device, improving the practicability of the silt cleaning device.
