Description

Technical Field

[0001] This utility model relates to the field of multiple frequency sieve technology, specifically a novel self-repairing multiple frequency sieve structure. Background Technology

[0002] The multi-frequency screen adopts a design with a fixed screen box and only screen vibration. It achieves composite vibration through multiple independent excitation sources (such as low-frequency vibration driving the screen box and high-frequency vibration driving the screen). The screen can move with variable frequency, amplitude, and trajectory. For example, the screen can be stretched and relaxed by shear springs to enhance its self-cleaning ability.

[0003] When a multi-frequency screen is under maintenance, a three-way chute is usually added above the vibrating screen to achieve material switching. The three-way chute has a flap valve inside. When the vibrating screen stops operating for maintenance, the material is guided to another direction through the flap valve of the three-way chute to achieve material switching. This method occupies a lot of space. The three-way chute and the guide chute will occupy a lot of civil engineering space, and the manufacturing materials required for the chute will generate additional costs. The material will cause wear and tear due to long-term friction against the shaft, affecting the use. Utility Model Content

[0005] To achieve the above objectives, this utility model discloses a novel self-repairing multi-frequency sieve structure. The technical solution adopted includes a multi-frequency sieve with a feed inlet at the top. The characteristic feature is that: below the feed inlet is a discharge hopper, to the right of the discharge hopper is a screen, below the screen is a discharge chamber, and to the left of the screen is a flipping mechanism at the discharge hopper. The flipping mechanism includes a rotating shaft, which is rotatably connected to the side plates of the sieve box on both sides of the multi-frequency sieve. A crank is fixedly connected to the rotating shaft extending to the outside, and the other end of the crank is connected to a push-pull mechanism. The push-pull mechanism is rotatably connected to the side plates of the sieve box. A baffle is fixedly connected to the rotating shaft inside the multi-frequency sieve, and a protective mechanism is provided on the rotating shaft.

[0006] As a preferred technical solution of this utility model, bearing seats are provided on both sides of the side plate of the screen box, and the rotating shaft is rotatably connected to the multi-frequency screen through the bearing seats.

[0007] As a preferred technical solution of this utility model, the push-pull mechanism includes an electric push cylinder, a bracket rotatably connected in the middle of the electric push cylinder, the bracket being fixed to the outside of the multi-frequency screen, and the output end of the electric push cylinder being rotatably connected to the crank.

[0008] As a preferred technical solution of this utility model, the protective mechanism includes an arc-shaped plate, which is fixedly connected to the rotating shaft and a protective plate, which is inverted V-shaped.

[0009] As a preferred technical solution of this utility model, the baffle has a three-layer structure with a bottom plate in the middle and lining plates on both sides.

[0010] As a preferred technical solution of this utility model, splash guards are provided on both sides of the baffle. A first rib is longitudinally fixedly connected to the liner between the two splash guards on the left side of the baffle. There are multiple first ribs, which are linearly arrayed on the baffle. Second ribs are transversely fixedly connected between the first ribs.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this utility model controls the position of the baffle through the flip-plate mechanism to realize the flow trajectory of the material, thereby changing the material trajectory at low cost and without occupying space, so that the material no longer enters the inside of the frequency screen, providing a maintenance and repair environment. By setting a protective mechanism, the impact force of the material on the rotating shaft can be reduced and direct contact between the material and the rotating shaft can be prevented, thereby preventing damage to the rotating shaft.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 like Figures 1 to 6 As shown, this utility model discloses a novel self-repairing multi-frequency screen structure. The technical solution includes a multi-frequency screen 1, with an inlet 101 above the screen 1, a discharge hopper 103 below the inlet 101, a screen 102 to the right of the discharge hopper 103, and a discharge chamber 106 below the screen 102, making the discharge chamber 106 and the discharge hopper 103 two cavities. However, the two cavities are connected only at the inlet 101. The discharge hopper 103 is located to the left of the screen 102. A flip-plate mechanism 2 is provided, which includes a rotating shaft 4. The rotating shaft 4 is rotatably connected to the screen box side plates 104 on both sides of the multi-frequency screen 1. Bearing seats 5 are provided on both sides of the screen box side plates 104. The rotating shaft 4 is rotatably connected to the multi-frequency screen 1 through the bearing seats 5. A crank 6 is fixedly connected to the rotating shaft 4 extending to the outside. The other end of the crank 6 is connected to a push-pull mechanism. The push-pull mechanism includes an electric push cylinder 7. A bracket 8 is rotatably connected to the middle of the electric push cylinder 7. The bracket 8 is fixed to the outside of the multi-frequency screen 1. The output end of cylinder 7 is rotatably connected to crank 6. A baffle 3 is fixedly connected to the rotating shaft 4 inside the multi-frequency screen 1. A protective mechanism 403 is provided on the rotating shaft 4. The protective mechanism 403 includes an arc plate 401, which is fixedly connected to the rotating shaft 4. A protective plate 402 is fixedly connected to the arc plate 401. The protective plate 402 is inverted V-shaped. The protective plate 402 mainly reduces the impact force of the material on the rotating shaft 4 and prevents the material from directly contacting the rotating shaft 4, thus preventing the rotating shaft 4 from being worn. The baffle 3 has a three-layer structure with a bottom plate 301 in the middle and liners 302 on both sides. Anti-splash plates 305 are provided on both sides of the baffle 3. A first stiffener 303 is longitudinally fixedly connected to the liner 302 between the two anti-splash plates 305 on the left side of the baffle 3. There are multiple first stiffeners 303, which can prevent large splashes when the material hits the protective plate 402. They are linearly arrayed on the baffle 3. Second stiffeners 304 are transversely fixedly connected between the first stiffeners 303 to increase strength.

[0016] The working principle of this utility model is as follows: During normal screening, the electric push cylinder 7 is in a retracted state, and the baffle 3 is located on the left side of the feed inlet 101, connecting the feed inlet 101 with the screen 102 above. The material falls onto the screen 102 through the guide of the baffle 3. The material is screened by the vibration of the screen 102. Small particles of material enter the discharge chamber 106 through the screen 102 and are discharged. Large particles of material are discharged from the discharge port 105 on the right side of the screen 102. When the frequency screen 1 needs maintenance, the telescopic rod of the electric push cylinder 7 is pushed out, causing the baffle 3 to rotate to the right, connecting the feed inlet 101 with the discharge hopper 103. The material is discharged directly from the discharge outlet 1031 through the discharge hopper 103, thus allowing safe maintenance of the frequency screen 1. At this time, the protective plate 402 can reduce the impact force of the material on the rotating shaft 4 and prevent the material from directly contacting the rotating shaft 4.
