Example 1:

an ultrasonic vibration sieve, as shown in fig. 1, comprises a box 100, an ultrasonic transducer 400, a screen 200 and two material distributing plates 300, wherein the box 100 is provided with a feed port 110, a material is introduced into the box 100 through the feed port 110, the screen 200 is horizontally arranged in the box 100, the two material distributing plates 300 are arranged between the feed port 110 and the screen 200, the material introduced from the feed port 110 falls on the material distributing plates 300 firstly, one ends of the two material distributing plates 300 are close to each other, the two material distributing plates 300 can be rotated and inclined so that the ends, far away from each other, of the two material distributing plates 300 gradually move from the edge close to the screen 200 to the center of the screen 200, the two material distributing plates 300 are in a horizontal state in an initial state, the material can fall on the material distributing plates 300, the material on the material distributing plates 300 can slide onto the screen 200 and can fall to the edge of the screen 200 firstly after the material distributing plates 300 are rotated and inclined, as the rotation angles of the material distributing plates, the material that is located above it can fall into the central point of screen cloth 200 gradually to make the material can distribute on screen cloth 200 evenly, certainly need restrict the size of branch flitch 300, it still has certain clearance with screen cloth 200 when making branch flitch 300 perpendicular to screen cloth 200, the rotation slope process of branch flitch 300 is the circulation reciprocal simultaneously, can make the material that constantly adds by feed inlet 110 all the time evenly distribute on screen cloth 200 like this, ultrasonic transducer 400 is connected with screen cloth 200, thereby the ultrasonic transducer 400 can drive screen cloth 200 vibration thereby the completion to the step of material screening after the material falls on screen cloth 200 completely.

In order to enable the two material distributing plates 300 to achieve the function of rotating and tilting, as shown in fig. 1 and 2, a rack 120 is vertically arranged in the box 100, the rack 120 is a polygonal prism, two first tooth portions 121 oppositely arranged are arranged on the rack 120, the two first tooth portions 121 are arranged on two oppositely arranged outer walls of the rack 120, a first gear 310 is arranged on the two material distributing plates 300, two parallel fixing rods 130 are assumed in the box 100, the first gear 310 and the material distributing plates 300 are sleeved on the fixing rods 130, a transmission bearing is arranged between the first gear 310 and the fixing rods 130, a transmission bearing is also arranged between the material distributing plates 300 and the fixing rods 130, the transmission bearing is arranged to enable the first gear 310 and the material distributing plates 300 to smoothly rotate, the two first gears 310 are respectively matched with the two first tooth portions 121 on the rack 120, the two first gears 310 are located on two sides of the rack 120, so that the two material distributing plates 300 simultaneously rotate in opposite directions when the rack 120 ascends or descends, since the two material distribution plates 300 are provided, the materials on the two material distribution plates 300 can fall onto both side edges of the screen 200, thereby enabling the materials to be uniformly distributed on the screen 200.

In order to enable the rack 120 to move up and down, an extension rod 140 is connected to the inner top of the box 100, one end of the extension rod 140, which is away from the inner top of the box 100, is connected to the rack 120, the extension rod 140 serves to fix the rack 120, the extension rod 140 contracts when the rack 120 ascends, the extension rod 140 is extended when the rack 120 descends, a second tooth portion 122 is provided on an outer wall of one side of the rack 120, the second tooth portion 122 is located on an adjacent side of the two first tooth portions 121, a motor 500 is provided on one side of the box 100, specifically, the motor 500 can be fixed to an outer wall of the box 100, a second gear 510 is connected to an output end of the motor 500, the second gear 510 is engaged with the second tooth portion 122, because the motor 500 has a certain distance from the rack 120, an extended shaft portion can be connected to the output end of the motor 500, a distal end of the extended shaft portion extends to the rack, so that the rack 120 can be put on the body or lowered, and the two material separating plates 300 can be rotated in opposite directions.

In actual use, because the screen 200 is too large, there is less support within the rack, resulting in differential tension at different locations on a single screen 200. The net rack inner ring 240 is large and unsupported, so that the middle part of the screen 200 is large in bending deformation and serious in stress concentration, secondary vibration is easy to generate due to the relaxation of the screen 200, the screen 200 can be damaged early under the action of alternating stress, and not little economic loss is caused. Meanwhile, ultrasonic waves act on the outer ring of the screen 200 frame, so that the stress difference of the inner ring and the outer ring of the screen 200 frame is large, and the service life of the screen 200 is shortened. The screen mesh 200 is bent and deformed to affect the effective screen passing area of the screen mesh, so that the materials which should pass through the screen cannot pass through the screen, and the screening efficiency is reduced.

In order to solve the above problems, in the present invention, as shown in fig. 3, a screen 200 includes a frame body and a screen surface 210 distributed on the frame body, the frame body includes an outer ring 220, a middle ring 230 and an inner ring 240 which are concentric, the outer ring 220, the inner ring 240 and the middle ring 230 are connected by a support rod 250 extending along a radial direction thereof, by increasing the number of ring bodies, the number of points fixed to the screen surface 210 on the frame body can be increased, thereby increasing the tension of the screen surface 210, making the screen surface 210 more flat, and simultaneously making the overall tension of the screen 200 be uniformly distributed, thereby improving the durability of the screen 200, making the screening efficiency of the screen 200 higher, and certainly, in order to further improve the screening efficiency of the present invention, a plurality of screen 200 may be provided, the plurality of screen 200 are spaced from top to bottom in a box 100, a circular screen 200 is shown in fig. 3, and therefore, a semicircular fan panel should be adopted for the corresponding material distributing plate 300, if the screen 200 is rectangular, the corresponding material distributing plate 300 may be a common rectangular plate.

In order to fix the screen 200 in the box 100, clamping plates 150 are disposed on two opposite sidewalls in the box 100, edges of the screen 200 are clamped by the clamping plates 150 to fix the screen 200, an upper elastic member 151 and a lower elastic member 152 are further disposed between the clamping plates 150, and the screen 200 is fixed between the upper elastic member 151 and the lower elastic member 152, specifically, the upper elastic member 151 and the lower elastic member 152 may be springs or shock-absorbing rubber pads, and the arrangement of the upper elastic member 151 and the lower elastic member 152 can play a role of protecting the screen 200 and preventing the screen 200 from being damaged due to severe rigid vibration.
