[0025] As Figure 1 , Figure 2 , Figure 3 And Figure 4As shown, the working principle of the large-scale water conservancy machinery grille trash cleaner mainly based on the synergistic effect of the following several key components. First, the power motor 9 as the power source of the entire device, through the output shaft to drive the transmission gear to rotate, the transmission gear between the left end of the power motor 9 output shaft and the left end of the driven roller shaft is connected through the transmission chain, so as to transmit power to the driven roller. The driven roller starts to rotate after obtaining power. Since its roller shaft is fixedly connected with the trash conveying support plate A1 and the trash conveying support plate B3 through bearings at both ends, the driven roller can stably rotate between the two support plates. The rotation of the driven roller drives the grille type conveying belt 4 to move. The driven roller inside the grille type conveying belt 4 at both ends also rotates to assist the stable operation of the grille type conveying belt 4. The driven roller is also connected with the trash conveying support plate A1 and the trash conveying support plate B3 through bearings at both ends of its roller shaft to ensure smooth rotation. The grille type conveying belt 4 is driven by the grille type conveying belt 4. The multiple rake tooth integrated frames 5 and the multiple trash rakes 6 fixedly arranged on the outer wall of the rake tooth integrated frame 5 move under the driving of the grille type conveying belt 4. When the trash rake 6 contacts with the water body, it can collect the sundries in the water body. With the rotation of the grille type conveying belt 4, the trash rake 6 with sundries is driven to the top of the discharge cover 8. The setting of the discharge cover 8 can guide the sundries to be discharged smoothly, ensuring the continuity of the trash cleaning process.

[0026] As Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the cutting and cleaning device 11 is connected at the center of the rear end of the clean-up conveying support plate A1 and the clean-up conveying support plate B3, and includes a fixing screw 12, a fixed side plate 13, a metal integrated plate 14, and a cleaning cutter 15. The left and right ends of the metal integrated plate 14 are welded with the fixed side plate 13, and the front half of the two fixed side plates 13 are respectively attached to the outer wall of the left end of the clean-up conveying support plate A1 and the outer wall of the right end of the clean-up conveying support plate B3. The two fixed side plates 13 are fixedly connected with the clean-up conveying support plate A1 and the clean-up conveying support plate B3 through a plurality of fixing screws 12. The stability of the cutting and cleaning device 11 during work is ensured by the fixed connection mode of the fixing screw 12, which can withstand various forces generated during cleaning and cutting. A plurality of cleaning cutters 15 are equidistantly arranged on the outer wall of the front end of the cutting and cleaning device 11. The metal integrated plate 14 is located behind the rear end outer wall of the grid conveying belt 4 and does not contact the clean-up tines 6. The plurality of cleaning cutters 15 are respectively located between two adjacent clean-up tines 6 and do not contact the clean-up tines 6. This layout enables the cleaning cutter 15 to accurately cut the weeds and other sundries wrapped on the clean-up tines 6. The cleaning cutter 15 does not contact the clean-up tines 6, which ensures that the clean-up tines 6 will not be damaged during cutting. The metal integrated plate 14 is located behind the rear end outer wall of the grid conveying belt 4, which enables the cutting and cleaning device 11 to clean the clean-up tines 6 without interfering with the normal operation of the grid conveying belt 4. Since the metal integrated plate 14 does not contact the clean-up tines 6, unnecessary wear and damage to the clean-up tines 6 are avoided.

[0027] As Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the front half of the cleaning cutter 15 is provided with a curved surface, which can better adapt to the space shape between the cleaning rake teeth 6, so that the cleaning cutter 15 is more smooth when cutting, and the cutting efficiency is improved. On the other hand, the curved surface design makes the front end of the cleaning cutter 15 not contact with the rake integrated frame 5, avoiding damage to the rake integrated frame 5. The front end of the cleaning cutter 15 does not contact with the rake integrated frame 5, and the front end and the upper and lower ends of the cleaning cutter 15 are provided with cutter edges. The cutting and cleaning device 11 of the water conservancy machinery grille trash cleaner mainly plays a role in the following ways: the front end and the upper and lower ends of the cleaning cutter 15 are provided with cutter edges, which increases the contact area and angle of cutting, so that no matter in which direction the weeds and other sundries are wound on the cleaning rake teeth 6, the cleaning cutter 15 can effectively cut. When the grille type conveying belt 4 rotates, the cleaning rake teeth 6 with weeds and other sundries wound thereon pass through the cutting and cleaning device 11. The cleaning cutter 15 utilizes its special design and layout to quickly and accurately cut off the wound sundries, thereby ensuring that the cleaning rake teeth 6 can continuously and efficiently clean the trash.

[0028] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
