It connects, is set on a side end cap there are one feeding mouth, another feeding mouth is equipped on the upper lid of screen box body, in another lateral end cap
Equipped with discharge port, this structure can meet the needs of screening efficiency, while the precision sieved is also higher, but shortcoming is, on
Partition board is equipped between two layers lower, a feeding mouth is arranged on a side end cap, another feeding mouth is arranged on the upper lid of babinet,
Two feeding mouths feeding and from a discharge hole for discharge simultaneously, therefore easily there is buildup, moreover, vibrator is arranged in the centre of screen box
Position, therefore material is being sieved as vibrator is moved forwards to discharge port in hopper, material operation is slow, to influence screening effect
Rate.
Invention task
The task of the present invention is a kind of topology layouts of proposition rationally, oversize can not will produce buildup quickly through discharge port
A kind of rectangular swinging screen.
The task of the present invention is what is completed in this way, it includes vibrator, screen box, holder, feed inlet, it is characterised in that：Into
Material mouth setting is fixed in screen box front end by flange, the rear lower of screen box is provided with undersize material outlet, the tail portion of screen box is set
It is equipped with oversize discharge port, the feed inlet is to be made of feeding seal component, and feeding seal component includes sealing cover, charging
Mouthful, the centre of the sealing cover is machined with feed inlet, and is placed in the internal cavities of sealing cover and slips flitch, and slips on flitch
It is even to be machined with sieve pore, connecting plate is installed on symmetrical two sides in inner cavity of sealing cover, connecting plate is to stand placement, the company
The fitting of fishplate bar one end is fixed on the inner wall at the top of sealing cover, and the other end of the connecting plate is fixed on the two side for slipping flitch
On.The shape of the feed inlet can be made into circle, square, taper, and the shape for slipping flitch is V-shaped.
Subject to side in the length and sealing cover of the connecting plate is adjacent to, the top for slipping flitch is in rectangular swinging screen
The center of feed inlet.
The present invention has the following effects that, the technical program upper layer and lower layer is equipped with support net between sieving hopper, in screening on
Material in layer sieve hopper, which not will produce, sinks to lower screen hopper, is quickly flowed for material there are two discharge port and at the same time setting
Go out, not will produce buildup, the front lower portion in screen box body is arranged in vibrator, and quickly operation passes through sieve to material after feed inlet feeding
To discharge port after mesh screen point, to improve effect screening efficiency；The technical program can solve material and uniformly flow to screen surface,
And also avoid material and directly impact sieve, material can be sieved adequately, to improve screening efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；Fig. 2 is feeding seal component structure diagram；Fig. 3 is V-type feed inlet
Structural schematic diagram.
Drawing explanation：1, vibrator, 2, feed inlet, 3, erecting by overhang, 4, screen box, 5, on-the-sieve material outlet, 6, screenings
Material outlet.
Specific implementation mode
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
As shown in Figure 1, screen box 4 is connect by turning round knot with holder, the front lower portion of the screen box is equipped with specific embodiment
Vibrator 1, the setting of feed inlet 2 are fixed in 4 front end of screen box by flange, and upper sieve hopper and lower screen material are equipped in the screen box
Case, the upper and lower layer sieve hopper centre is equipped with support net, and upper and lower sieve hopper is interior equipped with limes marginis sieve, and the both ends of screen box are set
There is end cap, the end cap is hinged with babinet, the rear lower of screen box is provided with undersize material outlet 6, the tail portion of screen box is provided with
Oversize discharge port 5 is equipped with erecting by overhang 3 on screen box.
The feed inlet 3 is to be made of feeding seal component 3-1, and feeding seal component includes sealing cover 3-5, feed inlet
3, the centre of the sealing cover is machined with feed inlet 3, and the shape of the feed inlet can be made into the geometry such as circle, square, taper
Shape, the feed inlet circular of the technical program, and be placed in the internal cavities of sealing cover 3-1 and slip flitch 3-3, it is described to slip
The shape of flitch is V-shaped, and slips and be uniformly machined with sieve pore 3-6 on flitch, is placed in sealing cover cavity to ensure to slip flitch
It does not fall off, connecting plate 3-4 is installed on symmetrical two sides in inner cavity of sealing cover, in the length and sealing cover of the connecting plate
Side be adjacent to subject to, furtherly, connecting plate is to stand placement, and the fitting of described connecting plate one end is fixed at the top of sealing cover
On inner wall, the other end of the connecting plate is fixed on the two side for slipping flitch, and sealing cover is fixed by flange 3-2 with screen box.
The top for slipping flitch slips the plane of flitch in sealing cover in the center of rectangular swinging screen feed inlet
Distance gradually increases.
In summary, the technical program include vibrator 1, feed inlet 2, screen box 4, oversize outlet 5, screenings outlet 6,
Feed inlet 2, sealing cover 3-5, flitch 3-3, connecting plate 3-4, flange 3-2 are slipped, overcomes the material after prior art screening to going out
Easy buildup when material mouth, the low problem of screening efficiency.
When work, material feeds screen box by feed inlet, under the vibration of vibrator material levels sieve hopper in until
It after screening, is flowed out by oversize discharge port and screenings discharge port, not will produce buildup, and material energy is until sufficient sieve
Point；Material is flowed to and is slipped on flitch after the entrance of rectangular swinging screen feed inlet, and material is through slipping the mesh uniform flow of flitch to following
Compass screen surface is V-type due to slipping flitch shape, therefore material smooth can flow to sieve by sieve pore, avoid material and directly impact sieve,
And can guarantee that material is uniformly left to screen surface, make full use of entire sieve to be sieved, to improve screening efficiency.
In the present invention unless specifically defined or limited otherwise, the arts such as term " installation ", " connected ", " connection ", " fixation "
Language shall be understood in a broad sense, for example, it may be fixedly connected, may be a detachable connection or integrally connected, can be two members
