Abstract
The utility model discloses an upper cover of a vibration sieve, comprising a flange and a material feeding port. A circular upper cover is applied to replace the conical upper cover, the effects for enhancing the rigid and avoiding the deformation can be achieved even if the upper cover is made of same material. When in production, the two covers are sealed prophetically, and air or liquid is applied to pressurize inwards, two circular cover bodies can be pressed within a few minutes. The upper cover has the advantages of simple production procedure and labor and time conservation.
Description
Technical field:
The utility model relates to vibrating machine, particularly a kind ofly stressedly evenly is difficult for producing resonance, and is in light weight, intensity is high, makes to be easy to revolve the sieve loam cake that shakes.
Background technology:
The existing sieve loam cake that shakes that revolves is to be provided with a charge door a conical lid upper end, encloses flange in its lower end to being externally connected with one.The problem that this structure exists is that stress is inhomogeneous, easily produces resonance and distortion, is not suitable on the airtight screen(ing) machine, is that its complex manufacturing technology, processing are slow in addition.
Summary of the invention:
The purpose of this utility model provide a kind of in light weight, intensity is high, be difficult for to produce resonance and distortion, make and be easy to revolve the sieve loam cake that shakes.
Technical solution of the present utility model is finished as follows, and it includes flange and charge door, it is characterized in that: be connected with a circular arc lid between charge door and flange.It is conical that cap portion of the present utility model adopts circular arc to replace, use same material can reach the enhancing rigidity, on-deformable effect, adopt the sealing of two lid peripheries during production, inwardly pressurize with gas or liquid, a few minutes just can extrude two circular arc lids, and manufacturing process is simple, saves labor.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is adding man-hour, with pad one deck sealing ring between two cover materials edges, periphery flange 3 is used bolting, open a little closed hole with aerostatic press or hydraulic press from charge door 1 then, inwardly pressurization, two lids are pressed bulging deformation lid 2 in the arc-shaped, at last little closed hole is enlarged charge door is installed.This circular arc lid has rational in infrastructure, good rigidly, not yielding, advantage fast easy to process.
Claims (1)
1, a kind of sieve loam cake that shakes that revolves, it includes flange and charge door, it is characterized in that: be connected with a circular arc lid between charge door and flange.
