Grab bucket for water conservation trash removal

Abstract

The invention discloses a grab bucket for water conservation trash removal. The grab bucket comprises a fixed shell. A left bucket body and a right bucket body which are hinged to each other to be matched are arranged at the bottom of the fixed shell. A left hydraulic cylinder and a right hydraulic cylinder are arranged on the two sides in the fixed shell obliquely and correspondingly. Piston rodsof the left hydraulic cylinder and the right hydraulic cylinder are connected with the outer walls of the left bucket body and the right bucket body correspondingly. The bucket walls of the left bucket body and the right bucket body are each provided with a water draining through hole array. The bottom edges of the left bucket body and the right bucket body are both provided with sawteeth capableof being matched with a trash rack. A pulley is arranged at the top of the fixed shell. A traditional integral type linkage structure is abandoned, the left hydraulic cylinder and the right hydrauliccylinder drive the left bucket body and the right bucket body correspondingly and independently, thus the grab bucket is opened or closed, various trash substances can be grabbed and is not liable tofall, and grabbing force is large. The pulley achieves a movable pulley function, thus more and heavier trash can be grabbed, and loading capacity is improved.

Description

Technical field [0001] The invention relates to the technical field of water conservancy equipment, in particular to a grab bucket for water conservancy cleaning. Background technique [0002] The use of trash cleaning buckets to remove the accumulated dirt in front of the trash racks of hydropower stations is a common method at home and abroad to remove garbage on the surface of the river. Most of the existing decontamination grabs are of integral linkage structure, which are generally composed of bucket frame, shovel teeth, rotating rake and hydraulic oil cylinder. When working, the hydraulic oil cylinder drives the rotating rake to rotate, so that the shovel teeth can be opened or closed to realize garbage grabbing. . Because the shovel teeth are arranged in a staggered manner, it can only grab large areas of garbage such as water and weeds, and the garbage that is smaller than the gap between the shovel teeth cannot be processed. Moreover, the structure of the shovel teeth i...

AI Technical Summary

Problems solved by technology

Since the shovel teeth are staggered, it can only grab large areas of aquatic plants and other garbage, and cannot handle garbage smaller than the shovel tooth gap, and the structure of the shovel teeth is also likely to cause uneven grasping and easy shaking of garbage.
