Multidirectional waggling type sand sieving device

Abstract

The invention discloses a multidirectional waggling type sand sieving device. The multidirectional waggling type sand sieving device includes a base, a sieving frame and moving blocks. The top of thebase is fixedly provided with vertical plates on the left side and right side symmetrically. A supporting plate is fixed between the two side vertical plates. The sieving frame is arranged on the upper portion of the supporting plate. The bottom of the sieving frame is connected with the supporting plate through a connecting spring. The bottom of the sieving frame is also connected with multiple vertical arranged sliding and moving bars at equal intervals. The lower ends of the sliding and moving bars pass through the supporting plate and extend downwards. The bottom of each sliding and movingbar is provided with a rolling wheel. The moving blocks are arranged between the base and an arranging plate. The top of each moving block is provided with a hook face and the bottom of each moving block is fixedly provided with a moving frame in the central position. The moving frame is in a front and rear opening design. Straight tooth surfaces are arranged symmetrically on the upper and lowersurfaces of an inner cavity of the moving frame. Incomplete gears are further arranged to stretch into the moving frame and to mesh with the straight tooth surfaces on both sides. According to the multidirectional waggling type sand sieving device, by enhancing irregular waggling of the sieving frame, sieving efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a screening device, in particular to a multi-directional shaking sand screening device. Background technique [0002] In building construction, fine sand is one of the most important building materials. However, the raw materials of sand are relatively rough and need to be filtered and screened. We mainly rely on sand screening machines to separate them from some sundries. This is very widely used. of sand. Sand screening machine, also known as Delong dry land sand screening ship, is suitable for sand and stone separation equipment on rivers, reservoirs, coal yards and construction sites. Very commonly used mechanical equipment is widely used in many fields, and its role in production and construction is becoming more and more obvious. [0003] Most of the existing sand screening devices have the problem of low efficiency. The reason is that the relative movement between the sand and the sieve plate is not very violent, and a...

Problems solved by technology

[0003] Most of the existing sand screening devices have the problem of low efficiency. The reason is that the relative movement between the sand and the sieve plate is not very violent, and a relatively direct way to strengthen this relative movement is to strengthen the insufficiency of the sieve plate. Regular movement, so the present invention proposes a multi-directional shaking sand screening device
