A hydraulic sludge grab

Abstract

The invention discloses a novel hydraulic sludge grab bucket which comprises two bucket parts which are oppositely arranged and can be opened and closed. One end of each conveying supporting rod device is hinged to the position of the rear portion of an upper top plate of the corresponding bucket part, and the other ends of the conveying supporting rod devices are hinged to an upper connecting block. A push oil cylinder is fixed to the top face of the middle portion of the upper connecting block. A pushing rod of the push oil cylinder penetrates the upper connecting block downwards and is fixedly provided with a push block. Push rods are arranged at the lower portion of the push block. The upper ends of the two push rods are hinged to the bottoms of the two ends of the push block. The other ends of the push rods are hinged to the positions of the front portions of the upper top plates of the bucket parts. The end faces, in contact with each other, of the two bucket parts are fixedly provided with buffering layers, and the two buffering layers abut against each other. The two bucket parts of the novel hydraulic sludge grab bucket are not liable to be impacted and damaged, the protection effect is good, the bucket parts are closed and opened by adopting the single push oil cylinder, the novel hydraulic sludge grab bucket is simple in structure and good in effect, and the two bucket parts can be closed firmly by adopting a permanent magnet block and a permanent magnet layer.

Description

Technical field: [0001] The invention relates to the technical field of sludge treatment, in particular to a hydraulic sludge grab. Background technique: [0002] Existing sludge grabs are generally mechanical or hydraulic. The mechanical structure is complex, troublesome to manufacture, and the effect is not ideal. The hydraulic structure generally uses a hydraulic cylinder directly installed at the rear of the bucket for pushing and pulling. , which requires a plurality of hydraulic cylinders. At the same time, there is generally no buffer mechanism at the end faces where the two buckets of the existing grabs are pressed against, which is easy to be damaged by collision. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a hydraulic sludge grab. Its two buckets are not easy to be damaged by collision, and the protection effect is good. It uses a single push cylinder to realize closing and opening,...

Problems solved by technology

[0002] Existing sludge grabs are generally mechanical or hydraulic. The mechanical structure is complex, troublesome to manufacture, and the effect is not ideal. The hydraulic structure generally uses a hydraulic cylinder directly installed at the rear of the bucket for pushing and pulling. , which requires multiple hydraulic cylinders. At the same time, there is generally no buffer mechanism at the end faces of the two buckets of the existing grab, which is easy to be damaged by collision
