Description

Technical Field

[0001] The utility model relates to the field of water inlet pollution cleaning equipment, in particular to a pollution cleaning rake bucket used for a trash rack. Background Art

[0002] The existing trash rack cleaning rake bucket has the following problems:

[0003] First, the bottom plate of the bucket is a whole piece of welded steel plate, which encounters great resistance when it comes into contact with water. When the bucket opens and moves downward to touch the water, the bottom plate of the bucket encounters the impact of the water flow, and its downward movement is blocked and its speed slows down, which can easily cause the traction wire rope to loosen, causing the entire bucket to lose balance and derail, resulting in a malfunction.

[0004] Second: the rake bucket and rake teeth are welded together, and some are even integrated. The rake teeth cannot adjust the inclination angle, and once the rake teeth are damaged, it is troublesome to repair and replace them.

[0005] Chinese patent CN208136851U discloses a trash-cleaning rake bucket for trash racks, in which a first leaking hole is arranged on a flap, and a second leaking hole is arranged on a side waist. The leaking holes can avoid the problem of the rake bucket being blocked from descending and the speed being slowed down, but the inclination angle of the rake teeth cannot be adjusted, and maintenance and replacement are also troublesome.

[0007] The innovation of the utility model lies in that the side wall of the bucket body of the utility model is provided with through holes and a grille shape, which can avoid the problem of downward obstruction and slow speed. The adjustable rake tooth assembly is designed. On the one hand, the rake teeth are easy to replace after being damaged. On the other hand, the width and inclination angle of the rake teeth can be adjusted according to the width and depth of the trash trough on the trash rack to adapt to it. It has good flexibility and is easy to adjust.

[0008] In order to achieve the above utility model purpose, the technical solution of the utility model is:

[0009] A trash cleaning rake bucket for a trash rack, comprising a bucket body with an arc-shaped bottom and an opening at the top; the bucket body comprises front and rear side walls and left and right side walls; through holes are evenly distributed on the left and right side walls; the front and rear side walls are integrated, comprising a plurality of arc-shaped longitudinal grid bars arranged in parallel, and transverse rollers are evenly arranged between adjacent longitudinal grid bars, and the longitudinal grid bars and the transverse rollers divide the front and rear side walls of the bucket body into a grid shape; the two ends of the transverse rollers are rotatably connected to the longitudinal grid bars; the end of the rear side wall of the bucket body close to the trash rack is provided with The adjustable rake tooth assembly comprises a positioning tube and a plurality of rake teeth with the same structure sleeved on the positioning tube; the two ends of the positioning tube are fixed on the rear side wall of the bucket body, and the positioning holes are evenly distributed in the circumferential direction and the axial direction on the positioning tube; the rake teeth comprise two parallel supporting tubes, one end of the supporting tube is provided with a positioning clamping ring, and the other end is a free end, a plurality of short rollers are evenly distributed in the axial direction between the two supporting tubes, and the two ends of the short rollers are rotatably connected to the supporting tubes; the positioning clamping ring is sleeved on the positioning tube and fixed by bolts.
