Detailed Description

The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

Example (b): as shown in fig. 1 to 7, a screening machine for grouper fry preparation comprises a ring frame unit 1, a screen unit 2 arranged on the ring frame unit 1, a lifting ring unit 3 arranged in the ring frame unit 1 and used for clamping the screen unit 2 on the ring frame unit 1, a radial hinge plate unit 4 arranged on the lifting ring unit 3 and used for jacking up the screen unit 2, and a rotating plate unit 5 arranged on the ring frame unit 1 and used for jacking up the radial hinge plate unit 4 and fastening the lifting ring unit 3.

In this embodiment, grouper fry material is the same with all other aquatic feeds, and its screening operation can not go on with iron orifice plate, wire netting, and first these two are too hard, and the fodder granule of whereabouts is smashed by colliding on a large scale easily, and second it is the fodder from taking a certain amount of moisture, and these two take place easily to meet the problem of water rust, so among the prior art, the screening mechanism of net cloth material, it is most common in fodder screening technology.

The annular frame unit 1 is used for installing the screen unit 2, the lifting ring unit 3 is used for tightening and installing the screen unit 2, the radial hinged plate units 4 are to be positioned on the lower surface of the screen unit 2 until the rotating plate unit 5 rotates to the radial hinged plate units 4, all the radial hinged plate units 4 are sequentially jacked upwards one by one, the screen unit 2 can be vibrated, the basic screening effect of the screen unit is substantially the same as the mode of vibrating the whole screen and the frame body, and the speed and the thorough degree of screening of the feed can be improved.

The screen unit 2 is naturally loosened after being used for a period of time, at the moment, the lifting ring unit 3 is firstly loosened, then the screen unit 2 is manually tightened outwards, and finally the lifting ring unit 3 is pressed tightly again, so that the screen which is originally loosened and invalid can be reused.

It should be noted, of course, that the number of retensionings of the screen unit 2 is also effective, otherwise the mesh opening size is too large to be achieved after several retensionings.

Also, the action of the radially hinged plate units 4 to lift the screen unit 2 upwardly does not exacerbate the relaxation of the screen, since the screen also has a downward bending amplitude in use, and the amplitude of the radially hinged plate units 4 to lift the screen is not much greater than this downward bending amplitude, or is smaller than this, and does not significantly accelerate the relaxation of the screen.

Finally, the rotating plate unit 5 has two different using states, one is to push the inclined surface of the radial hinged plate unit 4 to jack the radial hinged plate unit 4 upwards, and the other is to stir the rotary tightening outer ring surface of the lifting ring unit 3 to tighten and press the lifting ring unit 3 on the screen unit 2 again, which is very ingenious.

The annular frame unit 1 comprises an annular main body 101, a support column 102 arranged on the lower surface of the annular main body 101, and an annular groove 103 arranged on the inner annular surface of the annular main body 101 and used for installing the screen unit 2 and the lifting annular unit 3.

In this embodiment, the circular area of the inner ring of the circular ring main body 101 is smaller than that of the screen unit 2, and the opening position of the annular groove 103 can be properly located upward, so that the screen unit 2 can also be properly located upward, and reasonable feed particles trapped on the upper surface of the screen unit 2 can be relatively easily swept down.

The screen unit 2 includes a circular mesh cloth 201 having annular side edges provided on an inner top surface of the annular groove 103, and a tension cord 202 provided on the circular mesh cloth 201.

In this embodiment, the circular mesh cloth 201 is made of the existing common low-elasticity threads, such as nylon ropes, low-elasticity threads, and the like, the plurality of tensioning pull ropes 202 are uniformly arranged on the annular edge of the circular mesh cloth 201 at intervals, and when the circular mesh cloth 201 is found to be too loose, the lifting ring unit 3 is firstly loosened, then the tensioning pull ropes 202 are pulled down, and finally the lifting ring unit 3 is fastened.

The lifting ring unit 3 comprises a threaded column 301 arranged on the inner bottom surface of the annular groove 103, an internal thread cylinder 302 arranged on the threaded column 301, and a circular ring-shaped plate 303 arranged on the internal thread cylinder 302 and used for pressing the circular mesh cloth 201 upwards.

In this embodiment, the inner diameter of the circular annular plate 303 is larger than the inner diameter of the circular ring main body 101, the circular annular plate 303 is made of elastic plastic, and is folded in half and then placed in the circular groove 103, and then is released to place, and finally is used for jacking up and pressing the circular mesh cloth 201.

The threaded columns 301 and the internal thread cylinders 302 are arranged in a matched mode, and the number of the threaded columns is 4-6.

The radial hinge plate unit 4 comprises a protruding plate 401 arranged on the inner annular surface of the circular annular plate 303, a rotating plate 402 which is hinged on the protruding plate 401 and provided with a torsion spring in a hinge hole, and a radial plate body 403 which is arranged on the rotating plate 402 and provided with a pushing inclined surface and used for jacking up the circular mesh cloth 201.

In this embodiment, the vertical cross-sectional shape of the radial plate body 403 is an inverted right triangle or an inverted right trapezoid, and the rotating plate unit 5 crosses over the inclined surface thereof, so that the jacking and falling operation of the radial plate body 403 can be completed once, and the feed to be screened on the circular mesh cloth 201 is jacked up and falls down, thereby accelerating the screening speed and increasing the screening completeness.

In the hinge holes of the protruding plate 401 and the rotating plate 402, torsion springs are disposed, and the torsion springs maintain the radial plate 403 in a horizontal state attached to the upper surface of the circular mesh cloth 201 in the prior art, so that the corresponding radial plate 403 is also relatively light in weight and may be made of hard hollow engineering plastic.

Finally, the number and position of the radial hinge plate units 4 are independent of the threaded columns 301, and the height of the lower end edge of the radial plate body 403 is lower than the height of the upper end position of the pushing part of the rotating plate unit 5.

The rotating plate unit 5 includes a fixed orifice plate 501 disposed on an inner annular surface of the annular main body 101 and located below the annular groove 103, a rotating shaft 502 disposed on the fixed orifice plate 501, a radial stud 503 disposed on the rotating shaft 502, and a vertical orifice plate 504 disposed on the radial stud 503 and used for pushing the pushing inclined surface.

In this embodiment, an axial limiting bearing is disposed at the opening of the fixed orifice plate 501 to ensure that the rotating shaft 502 can rotate smoothly but cannot fall off, and the number of the radial studs 503 is not required to be the same as that of the radial hinge plate unit 4, so as to ensure that the vertical orifice plate 504 can be jacked up and cross over the radial plate 403 in the rotating process.

The vertical pore plate 504 is completely vertical, the amplitude of jacking the radial plate body 403 is the maximum, the larger the vertical pore plate 504 is away from the rotation center, the larger the amplitude of jacking the radial plate body 403 is, and therefore the vertical pore plate 504 is used for jacking and vibrating the radial plate body 403, and the vertical pore plate has the advantage of flexible and adjustable amplitude.

The rotating plate unit 5 further includes a fastening nut 505 disposed on the radial stud 503 and located on the radial inner side of the vertical orifice plate 504 and used for pressing and fixing the vertical orifice plate 504, a radial cylinder 506 screwed on the radial stud 503 and located on the radial outer side of the vertical orifice plate 504 and used for screwing the internal thread cylinder 302, and a bevel gear 507 disposed on the lower end face of the rotating shaft 502 and used for externally connecting a driving motor.

In this embodiment, the operation of loosening and then tightening the circular mesh cloth 201 needs to first loosen the internal threaded cylinder 302 and then tighten the internal threaded cylinder 302, and in this process, the operation can be completed by using the radial cylinder 506, which includes the following specific steps:

firstly, when normal vibration screening is carried out initially, the radial cylinder 506 rotates inwards in the radial direction and is in a retracted state, and the internal thread cylinder 302 cannot be touched;

secondly, after the circular mesh cloth 201 is loosened, the radial cylinder 506 is screwed outwards, the vertical hole plate 504 is swung downwards without touching the radial plate body 403, and at this time, the rubber radial cylinder 506 continuously passes over the outer annular surface of the internal thread cylinder 302 until the internal thread cylinder 302 is screwed downwards for a proper distance;

thirdly, after the circular mesh cloth 201 is tensioned again, the rotating direction of the rotating shaft 502 is changed, the radial cylinder 506 continuously passes over the outer ring surface of the internal thread cylinder 302, the direction in which the internal thread cylinder 302 is rotated by friction is the tightening direction, and finally the circular mesh cloth 201 is tensioned and then fixed.

In addition, when the vertical orifice plate 504 is retracted and not used, the vertical orifice plate 504 can be clamped together with the fastening nut 505, so that the vertical orifice plate 504 is not easy to loosen and hang down in the operation process of rotating and jacking the radial plate body 403.

Finally, the conical gear 507 is introduced, so that the motor outside the range of the support column 102 can effectively drive the rotating shaft 502 to rotate in a mode of adding another conical gear on the motor shaft, and the more important advantage is that the driving part including the motor is positioned outside the blanking area below the circular mesh cloth 201, so that the influence on the discharging action of the powder and the unqualified material is reduced to the maximum extent.

Further, an upper circular plate for covering and shielding the bevel gear 507 may be provided on the rotary shaft 502.

The screen unit 2 further includes a fixed ring 203 provided in the annular groove 103 and adapted to pass around the tension cord 202 from below, a movable ring 204 provided on the tension cord 202 and fitted over the threaded post 301, and a tension nut 205 provided on the threaded post 301 and adapted to push the movable ring 204 upward.

In this embodiment, after the circular mesh cloth 201 is loosened and the screening effect is significantly affected, the circular ring plate 303 is firstly lowered, and then the tensioning nut 205 is screwed up, at this time, the tensioning pull rope 202 bypasses the fixed ring 203, so that the circular mesh cloth 201 can be effectively expanded and tensioned outwards, and finally, the circular ring plate 303 is lifted upwards to compress the circular mesh cloth 201, which is the second tensioning effect of the screen, so that the whole loosening and then tensioning operation is simple and effective.

The number of the radial hinge plate units 4 is 3-5, and the radial hinge plate units are uniformly arranged on the inner annular surface of the circular annular plate 303 at intervals in a circumferential arrangement mode. The upper end of the vertical orifice plate 504 is shaped as a semi-circular end surface.

In this embodiment, a row of balls are further disposed on the semicircular end surface, so that sliding friction between the original end surface and the inclined surface is changed into rolling friction between the balls and the inclined surface, and thus the service lives of the vertical pore plate 504 and the radial plate body 403 can be remarkably prolonged, and the resistance when the inclined surface is pushed is also greatly reduced.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
