The conveying sieve plate is fixedly installed inside the frame. The vibrating motor is used to drive the frame to vibrate; there is a feeding port on the frame. During use, the materials at the feeding port fall onto the conveying sieve plate. The vibrating motor drives the frame to vibrate, and then drives the conveying sieve plate to vibrate; there are sieve holes on the conveying sieve plate, and impurities or specific small-sized materials fall through the sieve holes, and the materials that meet the requirements vibrate evenly on the conveying sieve plate and flow out from the discharging port.

[0004] However, the existing conveying sieve plate has a rigid flat plate structure. When the materials are mixed with sticky impurities (such as wet sludge), the sticky impurities will caking on the conveying sieve plate, forming protrusions on the surface of the conveying sieve plate or blocking the sieve holes, thereby affecting the effect of material distribution and further affecting the subsequent identification and sorting process.

[0029] The following will clearly and completely describe the technical solutions of the present utility model in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0030] As Figures 1 to 4 shown, a flexible vibrating distributor includes a frame 2, a flexible sieve surface 4 and a floating mechanism;

[0031] A cavity is formed within the frame 2, and the flexible screening surface 4 is unfolded and fixedly laid within the cavity. The frame 2 is provided with a feed end and a discharge end along its length direction; the flexible screening surface 4 is disposed between the feed end and the discharge end; the flexible screening surface 4 is inclined downward from top to bottom along the direction from the feed end to the discharge end;

[0032] The floating mechanism is arranged on the lower side of the flexible screening surface 4 and is used to change the vibration amplitude of the flexible screening surface 4.

[0033] Specifically, when the material reaches the flexible screening surface 4 from the feed end and rolls from the feed end to the discharge end, during the vibration of the frame 2, the overall vibration of the flexible screening surface 4 is driven. When the flexible screening surface 4 vibrates along with the frame 2, the floating mechanism changes the vibration amplitude of the flexible screening surface 4 during the vibration process. As a result, the vibration amplitude on the surface of the flexible screening surface 4 is different from that of the frame 2, and then the flexible impurities carried in the material will not form a hard crust on the flexible screening surface 4 and the upper plate of the sieve holes, which is beneficial to the subsequent identification and sorting process of the material.

[0034] According to an embodiment of the present invention, the length direction of the flexible screening surface 4 extends along the direction from the feed end to the discharge end, and the floating mechanism is arranged in multiple numbers, and the multiple floating mechanisms are arranged at intervals along the length direction of the flexible screening surface 4.

[0035] When the material falls onto the flexible screening surface 4 through the feed end, multiple groups of floating mechanisms are arranged at the bottom of the flexible screening surface 4, which can better change the vibration amplitude of the flexible screening surface 4.

[0036] It should be noted that the flexible screening surface 4 is made of non-rigid materials, and polyurethane, rubber or composite materials with certain flexibility can be selected.

[0037] According to an embodiment of the present invention, as Figure 2 shown, the floating mechanism includes a floating beam 3 and an elastic connecting member 5. Both ends of the floating beam 3 are respectively connected to the frame 2 through the same elastic connecting member 5. When the frame 2 vibrates, the elastic connecting member 5 and the flexible screening surface 4 vibrate under the drive of the frame 2. As a result, the floating beam 3 generates a vibration amplitude different from that of the frame 2 under the action of the elastic connecting member 5. The floating beam 3 is connected to the lower surface of the flexible screening surface 4, and the axis direction of the floating beam 3 is parallel to the lower surface of the flexible screening surface 4. Then, the floating beam 3 changes the tightness of the flexible screening surface 4, that is, changes the vibration amplitude of the flexible screening surface 4, so that the sticky impurities carried on the material are not easy to form a hard crust on the flexible screening surface 4 or block the sieve holes on the flexible screening surface 4.

[0038] In this example, the floating mechanism can also be in other forms. For example, the floating beam 3 is fixedly connected to the frame 2, and the floating beam 3 is connected to the lower surface of the flexible screening surface 4 through a spring, which can also achieve the purpose of changing the vibration amplitude of the flexible screening surface 4. Its essence does not deviate from the design concept of the present invention and should belong to the protection scope of the present invention.

[0039] In this embodiment, the floating beam 3 is a round rod. Two first through holes are provided on the frame 2. Both ends of the first round rod penetrate through the first through holes and are connected to the elastic connecting member 5. The floating beam 3 and the flexible sieve surface 4 are fixedly connected through a mounting plate. It should be noted that the diameter of the first through hole is larger than the diameter of the floating beam 3.

[0040] Of course, in this example, the floating beam 3 is arranged on the lower side of the flexible sieve surface 4. When not connected to the flexible sieve surface 4, when the elastic connecting member 5 vibrates, it can drive the floating beam 3 to lift the flexible sieve surface 4, and the purpose of changing the vibration amplitude of the flexible sieve surface 4 can also be achieved.

[0041] According to an embodiment of the present invention, the phase difference between the floating beam 3 and the frame 2 is 180°. Specifically, when the fixed beam 7 vibrates, under the vibration action of the annular rubber spring 501 and the frame 2, the floating beam 3 vibrates and generates a phase difference different from that of the fixed beam 7, and then can pull the flexible sieve surface 4 to be tightened and move up and down, changing the vibration amplitude of the flexible sieve surface 4 to prevent fine mud from caking on the flexible sieve surface 4. Preferably, the phase difference between the floating beam 3 and the fixed beam 7 is 180°.

[0042] According to an embodiment of the present invention, as Figure 2 shown, the elastic connecting member 5 includes an annular rubber spring 501. The annular rubber spring 501 is fixed inside the frame 2, and the floating beam 3 is embedded inside the annular rubber spring 501.

[0043] When the frame 2 vibrates, the annular rubber spring 501 vibrates, and then drives the floating beam 3 embedded in the annular rubber spring 501 to vibrate. Since the floating beam 3 is connected to the lower surface of the flexible sieve surface 4, therefore, the floating beam 3 drives the surface of the flexible sieve surface 4 to vibrate. Because the floating beam 3 is elastically connected to the frame 2, so, the vibration amplitude of the floating beam 3 is different from that of the frame 2, and further, the vibration amplitude of the flexible sieve surface 4 is different from that of the frame 2.

[0044] Of course, in this embodiment, the elastic connecting member 5 can be in other forms. For example, the elastic connecting member 5 includes a scroll spring, and the end of the floating beam 3 is fixedly connected inside the scroll spring, and the scroll spring is fixedly connected to the frame 2.

[0045] According to an embodiment of the present invention, as Figure 2 shown, the elastic connecting member 5 further includes a support 502;

[0046] The support 502 is fixedly connected to the frame 2. A round groove is provided inside the support 502. The annular rubber spring 501 is embedded in the round groove, and the floating beam 3 is fixedly connected to the annular rubber spring 501 through an annular flange.

[0047] Specifically, a first through hole is provided in the frame 2, and an annular flange is provided in the first through hole. The outer diameter of the annular flange is smaller than the diameter of the first through hole, and the diameter of the circular groove is larger than the diameter of the first through hole;

[0048] The floating beam 3 is fixedly connected to the annular rubber spring 501 through the annular flange;

[0049] The frame 2 and the support 502 cooperate to limit the annular rubber spring 501 in the circular groove.

[0050] Of course, the installation position of the annular flange can also be other positions. For example, the annular flange is installed on the side of the annular rubber spring 501 away from the frame 2 to achieve the purpose of fixing the annular rubber spring 501 and the floating beam 3. Its gist does not deviate from the design idea of the present invention and should belong to the protection scope of the present invention.

[0051] Specifically, the axis of the annular flange and the axis of the circular groove coincide with the axis of the annular rubber spring 501. The supports 502 are installed on both sides of the frame 2. The annular rubber spring 501 is embedded and fixed in the circular groove, and then the two ends of the floating beam 3 are respectively fixed inside the two annular rubber springs 501 to complete the installation. The support 502 is composed of a first ring plate, a mounting seat and a second ring plate. The inner hole of the first ring plate is the circular groove of the support 502. The first ring plate is placed in the mounting seat, the mounting seat is fixed to the frame 2, and then the second ring plate is installed on the side of the second ring plate away from the frame 2, so as to limit the annular rubber spring 501 embedded in the second ring plate between the frame 2 and the first ring plate, and then prevent the floating beam 3 fixed to the annular rubber spring 501 from moving along its axis.

[0052] The depth of the circular groove is adapted to the length of the annular rubber spring 501, and the annular rubber spring 501 can be completely embedded into the circular groove.

[0053] Of course, in this embodiment, the retention method of the annular rubber spring 501 can also be other forms. For example, a second through hole is provided in the support 502, the annular rubber spring 501 is fixedly connected in the second through hole, the aperture of the first through hole provided in the frame 2 is smaller than the diameter of the annular rubber spring 501, and a limiting block for limiting the floating beam 3 is fixedly connected to the side of the two supports 502 away from each other. The cooperation between the limiting block and the frame 2 can prevent the annular rubber spring 501 from moving along its length direction.

[0054] Of course, the distance between the two limiting plates is adapted to the length of the floating beam 3, and can prevent the floating beam 3 from moving in its axial direction.

[0055] According to an embodiment of the present invention, as Figure 3As shown, the frame 2 includes two fixed beams 7. Both ends of the flexible screen surface 4 are respectively connected to the two fixed beams 7, and the floating beams 3 are arranged at intervals between the two fixed beams 7. Among them, the two fixed beams 7 are respectively used to fix one end of the flexible screen surface 4 close to the feeding end and one end of the flexible screen surface 4 close to the discharging end.

[0056] Certainly, in this embodiment, if multiple sets of floating mechanisms are provided, then multiple floating beams 3 are arranged at intervals between the two fixed beams 7. On this basis, when the elastic coefficients of the elastic connectors 5 in each set of floating mechanisms are different, the effect of changing the vibration amplitude of the flexible screen surface 4 is better.

[0057] According to an embodiment of the present invention, the frame 2 further includes two side plates 8. The two side plates 8 are parallel to each other, and both fixed beams 7 are arranged between the two side plates 8. The direction from the feeding end to the discharging end is denoted as the length direction of the flexible screen surface 4, and the distance between the two side plates 8 is adapted to the width of the flexible screen surface 4. The two elastic connectors 5 are respectively connected to the two side plates 8, and one end of the floating beam 3 is connected to one side plate 8 through an elastic connector 5.

[0058] According to an embodiment of the present invention, as Figure 3 shown, flexible upper edges 10 are provided on two sides of the flexible screen surface 4 close to the two side plates 8. The flexible upper edges 10 are integrally formed with the flexible screen surface 4, and the flexible upper edges 10 are connected to the side plates 8.

[0059] Specifically, flexible upper edges 10 are provided on two sides of the flexible screen surface 4 close to the two side plates 8. The flexible upper edges 10 are integrally formed with the flexible screen surface 4, and the flexible upper edges 10 are connected to the side plates 8.

[0060] Since during the process of the material rolling on the flexible screen surface 4, the material may closely adhere to the side plates 8 and thus enter the gap between the side plates 8 and the flexible screen surface 4. To avoid this situation, by connecting a flexible upper edge 10 to each of the two sides of the flexible screen surface 4 close to the two side plates 8 respectively to cover the gap, it will not interfere with the movement of the flexible screen surface 4 when the flexible screen surface 4 adjusts its tightness under the action of the floating mechanism.

[0061] Certainly, in this example, if the width of the flexible screen surface 4 is designed to be greater than the distance between the two side plates 8, and the two sides of the flexible screen surface 4 close to the two side plates 8 are turned up and adhered to the two side plates 8 respectively, it can also achieve the purpose of preventing fine-grained materials from falling into the gap between the side plates 8 and the flexible screen surface 4. Its gist does not deviate from the design concept of the present invention and should belong to the protection scope of the present invention.

[0062] In this embodiment, the angle between the upper surface of the flexible sieve surface 4 and the horizontal plane is between 0° and 18°. The greater the inclination angle between the upper surface of the flexible sieve surface 4 and the horizontal plane, the faster the material rolls. The smaller the inclination angle between the upper surface of the flexible sieve surface 4 and the horizontal plane, the slower the material rolls. However, the better the effect of evenly spreading the material for screening. Therefore, the inclination angle of the flexible sieve surface 4 can be selected according to actual needs. In this embodiment, the angle between the flexible sieve surface 4 and the horizontal plane is 15 degrees.

[0063] Specifically, as Figure 1 shown, the vibrating feeder also includes a vibrating mechanism 1, a buffer mechanism 9, and a base 6. The bottom of the frame 2 is connected to the base 6 through multiple groups of buffer mechanisms 9. The vibrating mechanism 1 is installed on the frame 2 and is used to drive the frame 2 to vibrate. The vibrating mechanism 1 includes a vibrating motor and a vibrating beam. The output end of the vibrating motor is fixedly connected to the vibrating beam, and the vibrating beam is fixedly connected to both side plates 8. When the vibrating motor vibrates, it drives the vibrating beam to vibrate, thereby driving both side plates 8 and the fixed beam 7 to vibrate.

[0064] In this embodiment, the buffer mechanism 9 is a telescopic spring. The first mounting plate and the second mounting plate are respectively installed on both side plates 8 and the base 6 through multiple bolts. One end of the telescopic spring is fixedly connected to the side plate 8 through the first mounting plate, and the other end is fixedly connected to the base 6 through the second mounting plate.

[0065] Specifically, the base 6 is placed on the ground. The vibrating mechanism 1 vibrates, driving the side plates 8 and the fixed beam 7 to vibrate synchronously. The function of the buffer mechanism 9 is to buffer the overall frame 2. The material enters from the feeding end and rolls towards the discharging end through the flexible sieve surface 4. During the vibration process, the vibration phases of the fixed beam 7 and the side plates 8 are the same. Since the floating beam 3 is installed on the side plate 8 through the annular rubber spring 501 and the support 502, there is a phase difference between the floating beam 3 and the fixed beam 7. The different phases of the fixed beam 7 and the floating beam 3 cause the flexible sieve surface 4 fixedly connected to both ends of the two fixed beams 7 to be pulled tight and move up and down (i.e., the vibration amplitude of the flexible sieve surface 4 changes), thereby preventing the sticky impurities carried by the material from caking on the flexible sieve surface 4.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
