Sieve shaker

Abstract

The invention discloses a sieve shaker. The sieve shaking machine comprises a storage cavity and a supporting frame; the storage cavity is of a hollow cavity structure, and a filter screen is arrangedin the storage cavity; the interior of the storage cavity is divided into a plurality of cavities by the filter screen, and the mesh number of the filter screen is gradually increased from top to bottom; four rotating shafts A are arranged at the bottom of the storage cavity; the supporting frame is provided with a supporting block, a pressing block and a first hydraulic cylinder corresponding tothe rotating shafts A; a through groove A is arranged on the supporting block, the inner wall of the through groove A is in sliding fit with the side walls of the rotating shafts A; a cylinder body of the first hydraulic cylinder is connected with the supporting frame, and a piston rod of the first hydraulic cylinder is connected with the pressing block; the supporting frame is provided with a second hydraulic cylinder, a piston rod of the second hydraulic cylinder is coaxial with the storage cavity, a cylinder body of the second hydraulic cylinder is connected with the supporting frame through a universal joint coupling, and the piston rod of the second hydraulic cylinder is connected with the storage cavity through a spherical universal joint, so that the storage cavity rotates around acertain rotating shaft A; a discharging channel is arranged in the storage cavity; and a sieve shaking mechanism is arranged at the bottom of the supporting frame. The device of the invention can perform multi-stage screening at the same time.

Description

technical field [0001] The invention relates to the field of shaking screen machines, in particular to a shaking screen machine. Background technique [0002] Shaking sieve machines are widely used in all walks of life. Most of the sieving machines in the prior art include a sieve bed, and the structure of shaking sieve parts is arranged at the bottom of the sieve bed. This structure makes the screen shaker occupy a large space, and when multi-stage filtration is required, it can only be realized by adding a sieve bed, which not only increases the space occupied by the mechanism, but also increases the production cost. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a shaking screen machine capable of multi-stage screening and increase production efficiency. [0004] In order to realize the above-mentioned purpose of the invention, the present invention provides the followi...
