At the same time, it also reduces the burden of cleaning the garbage floating on the water surface for the staff, and effectively reduces the situation of small dirt clogging the filter 14, making the water flow smoother.

[0042] Furthermore, Figure 5 and Figure 2 As shown: through the cooperation between the lever 29 and the first spring 32, the staff can quickly limit the installation position of the filter 14 to ensure the stability of the filter 14, and after the staff loosens the lever 29, the first spring 32 rebounds to insert the lever 29 into the limiting hole 18 to ensure the stability of the position of the lever 29 and prevent the external environment from affecting the position of the lever 29 and causing the lever 29 to deviate.

[0043] Furthermore, Figure 6 and Figure 1 As shown: the position of the recycling box 7 is quickly positioned through the fixed cavity 21, which facilitates the subsequent installation of the fixed block 36 and the first fixed hole 22. At the same time, the solid waste transported to the recycling box 7 by the conveyor belt 5 is crushed through the crushing roller 34 to reduce its volume, avoid the large volume occupying a large amount of space in the recycling box 7, and require staff to frequently recycle and clean, which is time-consuming and labor-intensive.

The power equipment is managed uniformly through the control panel, which facilitates remote supervision and operation.

[0045] Working principle of the present invention:

[0046] When in use, the entire equipment is installed on site.

[0047] The auxiliary positioning mechanism and the water inlet pipe 1 are positioned and installed by the positioning bolts 41, so that the water inlet pipe 1 and the external equipment can be reinforced and installed during use, thereby improving the stability of the equipment during use and facilitating normal maintenance and processing. The two supporting clamps 38 allow the auxiliary external equipment to pass through the reserved cavity 43 through the closed state, thereby achieving a reinforced connection.

[0048] The driving motor 24 controls the transmission shaft 25 to rotate, and the conveyor belt 5 located on the outer wall of the transmission shaft 25 also rotates therewith. While rotating, the large pieces of garbage and aquatic plants floating in front of the water inlet 2 are collected through the hook 27, and transported to the top of the recycling box 7 as it rotates, so that it is transferred into the recycling box 7 for recycling.

[0049] After the garbage and aquatic plants enter the recycling box 7, they are guided by the guide plate 33 so that they can accurately fall between the two sets of crushing rollers 34 for crushing, which effectively reduces the connection and the volume of the aquatic plants, so that the recycling box 7 can store more garbage without the need for frequent cleaning by the staff. At the same time, it prevents large pieces of garbage and aquatic plants from being blocked above the filter 14, affecting the smooth flow of water, and also prevents them from being unable to be cleaned for a long time, resulting in decay and odor, affecting the surrounding environment.

[0050] At the same time, the water source entering the water inlet pipe 1 is filtered by the filter screen 14, and the small garbage carried in the water source that cannot be collected by the hook 27 is filtered.

[0051] When the surface of the filter 14 is clogged with small garbage after long-term use, the waterproof motor 19 controls the screw rod 10 to rotate, adjusts the position of the slider 11 at the screw rod 10, and then drives the connecting rod 12 connected to the slider 11 to adjust the position, so that the connecting rod 12 moves up and down along the screw rod 10, and the dirt on the surface of the filter 14 is cleaned back and forth by the cleaning brush on one side of the connecting rod 12 to prevent dirt from clogging the filter 14 and affecting the filtering effect.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
