[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a sewage treatment screen machine, the inclined conveyor belt mechanism 1 includes a pair of synchronous belts 14 for transmitting along the inclined direction; specifically, the inclined conveyor belt mechanism 1 also includes side plates 11 arranged in pairs, multiple rotating shafts 12 at both ends of which are respectively rotatably mounted on the midline position of the side plates 11, synchronous wheels 13 fixedly mounted on the rotating shafts 12 near the two ends and located on the inner side of the side plates 11, and a motor 15 fixed to the top of the side plates 11 and drivingly connected to the rotating shafts 12 at the top, and the synchronous belts 14 are drivingly connected to multiple synchronous wheels 13 on the same side.

[0024] The rake claw 1 2 includes a cross beam 1 21 whose two ends are respectively fixed to the outer peripheral wall of the synchronous belt 14 and a plurality of arc-shaped short rods 22 uniformly fixed to the cross beam 1 21 along the axial direction; the rake claw 2 3 includes a cross beam 2 31 whose two ends are respectively fixed to the outer peripheral wall of the synchronous belt 14, a clamping groove 311 uniformly arranged at the top of the cross beam 2 31 along the axial direction, an arc-shaped long rod 32 whose end is rotatably connected to the clamping groove 311, and a limit block 33 fixed to the outer wall of the cross beam 2 31 and located at the lower side of the clamping groove 311. Among them, the cross beam 1 21 and the cross beam 2 31 are alternately fixed to the synchronous belt 14, and it is best to set a cross beam 2 31 between every two cross beams 1 21.

[0025] The unloading mechanism 4 includes a slide plate 41 fixed at both sides of the front end to the rear side of the top end of the inclined conveyor belt mechanism 1, and a strip groove 411 corresponding to the arc-shaped short rod 22 and the arc-shaped long rod 32 is provided at the front end of the slide plate 41;

[0026] In summary, the motor 15 drives the paired synchronous wheels 13 and the synchronous belt 14 to operate through the rotating shaft 12, so as to realize the continuous and cyclic operation of the rake claw 1 2 and the rake claw 2 3. When in use, the bottom of the inclined conveyor belt mechanism 1 is extended into the sewage.

[0027] The arc-shaped short rod 22 and the arc-shaped long rod 32 are used to pick up the debris passing through the sewage and convey it upward; the arc-shaped long rod 32 can pick up larger debris. When the debris is transported to the top position of the inclined conveyor belt mechanism 1, it will flip backward and fall onto the slide plate 41, and slide backward with the slide plate 41. The arc-shaped long rod 32 passing the highest point will rotate relative to the slot 311, which will reduce its occupied space, so that the arc-shaped long rod 32 and the arc-shaped short rod 22 will pass through the strip slot 411 in sequence.

[0028] In order to increase the overall support strength and rigidity of the inclined conveyor belt mechanism 1 , a plurality of connecting rods 16 are vertically fixedly connected between the inner side walls of the side plates 11 , and both ends of the connecting rods 16 are respectively located in the inner cavities of the corresponding synchronous belts 14 .

[0029] For the slide plate 41, in order to prevent debris from jumping out from both sides of the slide plate 41 when sliding backward, side strips 42 are respectively provided on both sides of the top surface of the slide plate 41, and the front end of the side strips 42 is provided with a connecting plate 43 fixedly connected to the rear side of the top end of the inner wall of the side plate 11.

[0030] In order to further remove dirt on the arc-shaped short rod 22 and the arc-shaped long rod 32, a slide groove 421 is provided at the bottom of the front section of the side panel 11, and a scraper strip 44 is provided at the front front of the top of the slide plate 41, with both ends respectively slidingly engaged in the slide groove 421. The scraper strip 44 passes through the slide groove 421 and is respectively fixed with support blocks 441 at both ends. A guide rod 45 is vertically fixed to the rear wall of the support block 441, and a guide block 46 is provided at the rear end of the outer side wall of the side panel strip 42, which is slidably sleeved and matched with the rear end of the guide rod 45. A support ring 451 is fixed to the middle part of the guide rod 45, and a spring 47 is mounted on the part of the guide rod 45 located between the support ring 451 and the guide block 46. That is, when the arc short rod 22 and the arc long rod 32 pass through the strip groove 411, they will slide along the scraper bar 44, and the scraper bar 44 will move backward through the process of the support ring 451 compressing the spring 47, and the arc short rod 22 and the arc long rod 32 will be in an inclined state with the front lower and the back higher when they contact the scraper bar 44, thereby avoiding the phenomenon that the scraper bar 44 will block the arc short rod 22 and the arc long rod 32; and through the scraping action of the scraper bar 44, the debris attached to the arc short rod 22 and the arc long rod 32 is completely removed. Among them, the length of the strip groove 411 is preferably slightly larger than the length of the arc long rod 32.

[0031] In order to further improve the smoothness of the discharge of the debris on the slide plate 41, the rear portion of the top surface of the slide plate 41 is an inclined surface with a higher front and a lower rear.
