The clumped sludge and sundries are prevented from blocking and damaging the suction head and the flexible hose. The sludge and sundries in the collecting cavity carry a large amount of water. Since the sludge and sundries have a certain weight, the sludge and sundries gradually settle in the collecting cavity, and the water in the collecting cavity rises until the water level in the collecting cavity is higher than the bottom of the filter screen. Then, the water in the collecting cavity is automatically drained into the water channel through the filtration of the filter screen. The storage space in the collecting cavity only stores the sludge and sundries, and no water is stored. The storage space for the sludge and sundries in the collecting cavity is increased.

[0076] Embodiment 8:

[0077] The embodiment provides a water conservancy project dredging device, in addition to comprising the technical scheme of the above embodiment, further has the following technical features, the inlet end of the pump 2 is threadedly connected with one end of the flexible hose 22, and the discharge end of the pump 2 is threadedly connected with the vehicle body 1.

[0078] The structure of the pump 2 feeding end and the flexible hose 22 one end is stable, and the structure of the pump 2 discharge end and the vehicle body 1 is stable.

[0079] It is worth noting that the cutter 31 is composed of a plurality of blades longitudinally and transversely, and the intersection between the plurality of blades forms a rectangular cavity structure, which ensures that the clumped sludge and leaves can be squeezed out of the rectangular cavity structure in the cutter 31 after being cut by the cutter 31. The longitudinal section of the cutter 31 is an inverted isosceles triangle structure, which ensures that the cutter 31 can cut normally.

[0080] Working principle: when in use, the personnel push the handle 12 by hand and move the overall device forward under the action of the plurality of universal wheels on the vehicle body 1. When the vehicle body 1 moves forward in the water channel, the two hydraulic cylinders one 33 and the pump 2 and the hydraulic cylinder two 34 are connected to the power supply and started. The output shaft of the two hydraulic cylinders one 33 drives the feeding box 3 to move downward until the bottom of the feeding box 3 contacts the bottom of the water channel. At the same time, the flexible hose 22 is driven to elongate by the suction head 21. At this time, in the process of the overall device being pushed forward by the personnel, the sludge and debris in the water channel will flow into the feeding box 3. Subsequently, the pump 2 will suck the sludge and debris in the feeding box 3 through the flexible hose 22 and the suction head 21. At the same time, the hydraulic cylinder two 34 drives the cutter 31 to move up and down repeatedly through the U-shaped frame 32, which ensures that the cutter 31 can cut and break the clumped sludge and leaves, so as to ensure that the broken clumped sludge and leaves can be sucked into the suction head 21 and enter the collection cavity 19 through the flexible hose 22 and the discharge end of the pump 2, avoiding the blockage and damage of the suction head 21 and the flexible hose 22 caused by the clumped sludge and debris.

[0081] The sludge and debris entering the collection cavity 19 also carry a large amount of water. Since the sludge and debris have a certain weight, the sludge and debris will gradually settle in the collection cavity 19, and the water in the collection cavity 19 will rise until the water level in the collection cavity 19 is higher than the bottom of the filter screen 13. The water in the collection cavity 19 will pass through the filter screen 13 and enter the water guide pipe 11, and the water in the water guide pipe 11 will be automatically discharged into the water channel, ensuring that the water in the collection cavity 19 does not occupy the space of the collection cavity 19. At the same time, the broken leaves will also be collected in the collection cavity 19, avoiding the blockage of the water channel caused by the leaves.

[0082] When the sludge and debris in the water channel are cleaned, the personnel push the handle 12 to move the vehicle body 1 to a place where the sludge is concentrated for cleaning. The plug 15 is lifted to move upward in the limiting slot 17 until the tail end of the plug 15 completely leaves the insertion slot 16 and enters the limiting slot 17. The personnel hold the handle on the cover plate 14 and rotate it downward to open the cover plate 14. At this time, the personnel can clean the sludge in the collection cavity 19.

[0083] The embodiments of the present application are described above with reference to the drawings, and the embodiments and features in the embodiments of the present application can be combined with each other without conflict, and the present application is not limited to the above-described specific embodiments, and the above-described specific embodiments are only illustrative but not restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims, and all belong to the protection of the present application.
