Manually rotate the threaded rod 4 so that the two brushes clamp the screen. Set one end of the screen on the surface of the collecting roller 10. Drive the collecting roller 10 to rotate through the motor 7. At the same time, spray water on the top of the screen, so that the dust on the surface of the screen can be cleaned well. When using the recycling device 8, set the water at the bottom of the main body 1 of the cleaning machine. Pump the water through the connecting pipe 804 into the collecting pipe 806 by the water pump 805, and then spray the water onto the top of the screen through the nozzle 807. Because connecting holes are provided on one side of both the first brush 2 and the second brush 3, the water can be sprayed onto the screen well. When the screen passes through the inside of the main body 1 of the cleaning machine, the first brush 2 and the second brush 3 can clean the dust on the surface of the screen well. After the water passes through the screen, it passes through the filter screen 803. The filter screen 803 can play the role of filtering impurities, so that the clean water falls to the bottom of the inner wall of the main body 1 of the cleaning machine. After the screen passes through the inside of the main body 1 of the cleaning machine, it is set at the bottom of the connecting roller 811 and then wound around the surface of the collecting roller 10. Pull the rectangular bar 812 in the direction close to the support bar 810 through the first spring 814, so that the rubber strip 815 can be well pressed on the surface of the screen. In this way, the residual water on the screen can be scraped off to a certain extent by the rubber strip 815, and the residual water on the surface of the screen can return to the inside of the main body 1 of the cleaning machine through the inclined plate 808. In this way, the recycling of water resources is well realized. Before that, slide the baffle 817 into the notch 816, and then squeeze the rubber frame 819 into the rectangular groove 818. Then manually control the L-shaped plate 821 to slide inside the chute 820, and pull the L-shaped plate 821 upward through the second spring 822, so that the L-shaped plate 821 is set on one side of the baffle 817. In this way, the baffle 817 can be restricted inside the notch 816 by the L-shaped plate 821, and the notch 816 can be blocked when the filter screen 803 is not used in the notch 816. When using the connecting device 9, because one side of the four sides of the filter screen 803 is fixedly connected to one side of the inner wall of the connecting frame 802, slide the rectangular rod 902 into the fixing groove 901, pass the fixing plate 905 through the limiting groove 903 and then through the clamping groove 904. Manually control the fixing strip 908 to slide on the inner wall of the moving groove 907, and then slide the fixing strip 908 into the groove 909. Squeeze the fixing strip 908 in the direction close to the groove 909 through the third spring 910, so that the fixing strip 908 is well restricted inside the groove 909. In this way, the fixing plate 905 fixed together with the clamping block 906 can be restricted inside the clamping groove 904 by the fixing strip 908, and the rectangular rod 902 can be well restricted inside the fixing groove 901 by the fixing plate 905. In this way, the flexible filter screen 803 can be pulled open and then well set inside the connecting frame 802. Because there are multiple layers of filter screens 803,The reverse operation can disassemble the filter screen 803, thus facilitating the cleaning of each layer of the filter screen 803.,
