Description

Technical Field

[0008]

[0001] The utility model relates to the technical field of screening, and particularly relates to an anti-blocking vibrating screen mesh structure of a fructus aurantii screening machine. Background Technique

[0002] In the field of traditional Chinese medicine decoction pieces processing, fructus aurantii is a commonly used qi-regulating medicinal material. Its screening process is crucial for ensuring the retention of active ingredients and particle size uniformity. Most existing fructus aurantii screening equipment adopts a vibrating screen mesh structure, and different specifications of decoction pieces are classified by controlling the screen mesh aperture, which can be used for screening fructus aurantii impurities. However, impurities may cause blockage of the screen mesh holes. Therefore, the screen mesh needs to be cleaned.

[0003] In the prior art, some anti-blocking structures penetrate upward from the bottom of the screen mesh holes with sharp needles to dredge the holes. However, the sharp needle components generally have no shielding structure, and the falling impurities are likely to directly fall on the sharp needle components, which brings inconvenience to the cleaning of impurities. Therefore, it is necessary to design an anti-blocking vibrating screen mesh structure of a fructus aurantii screening machine to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-blocking vibrating screen mesh structure of a fructus aurantii screening machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-blocking vibrating screen mesh structure of a fructus aurantii screening machine, including a screen basket. A group of baffles are arranged below the screen basket. The upper surface of the baffle is provided with ejector rods corresponding to the mesh holes of the screen basket. A group of limiting plates are slidably connected to the ejector rods. The limiting plates can be kept flush with the top ends of the ejector rods by using an elastic limiting component. The elastic limiting component cooperates with a support member to be connected to the screen basket.

[0006] Preferably, the elastic limiting component includes limiting rods and springs. Two groups of the limiting rods are installed at the extending parts of both ends of the baffle. The limiting rods are T-shaped cylindrical parts. The two groups of limiting rods penetrate the extending parts of the ends of the limiting plates and are slidably connected to them. A group of springs are sleeved at the positions of each group of limiting rods between the baffle and the limiting plate. The two groups of limiting rods are connected to the support member.

[0007] Preferably, the support member includes a first support rod and a second support rod. The top ends of the two groups of limiting rods are respectively connected to a group of the first support rods. The top ends of the two groups of first support rods are respectively connected to the two ends of the second support rod to form a U-shaped structural part. The two groups of first support rods penetrate the connecting rods installed at the ends of the screen basket and are slidably connected to them. The support member can be locked through a locking component.

[0008] Preferably, the locking assembly includes bolts and threaded holes, and the second support rod is rotatably connected to a set of bolts, the bolts being threadedly connected to the threaded holes of the connecting rod.

[0009] Preferably, the diameter of the top rod is smaller than the diameter of the mesh opening of the sieve basket.

[0010] Preferably, two sets of sliding seats are symmetrically installed on both sides of the sieve basket.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the mesh openings do not need to be cleared, the elastic limiting component pushes the limiting plate upward, making its upper surface completely flush with the top of the top rod. Fine impurities such as fiber fragments and grease particles that are screened out will preferentially fall onto the surface of the limiting plate instead of falling directly into the gaps between the top rods. Pulling the support component upward will drive the elastic limiting component, baffle, top rod, and limiting plate to rise. The limiting plate will first contact the bottom of the screen basket, and then continue to pull, allowing the top rod to penetrate the limiting plate and insert along the mesh openings of the screen basket to clear the blocked mesh openings. The blocked mesh openings can be cleared when needed, but during screening, the screened impurities will not fall directly into the gaps between the top rods, improving the convenience of impurity cleaning.

[0013] 2. In this utility model, the spring force pushes the limiting plate to slide upward along the top rod, so that its upper surface is completely flush with the top of the top rod. The fine impurities screened off will preferentially fall onto the surface of the limiting plate instead of falling directly into the gap of the top rod. When the screen basket vibrates, the limiting plate will produce slight vibrations, and the attached impurities will automatically slide off under the coupling effect of gravity and vibration. When the mesh of the screen basket is blocked, the baffle is pulled up, causing the top rod to move upward. The limiting plate, limited by the screen basket, can slide down along the top rod, and the spring will be compressed. The top rod can penetrate the mesh of the screen basket to clear the blockage. After the top rod returns to its original position, the spring pushes the limiting plate to be flush again, and the system resumes the screening mode.

[0014] 3. The first support rod of this utility model is used to connect the top of the limiting rod to the second support rod. The second support rod and the two sets of first support rods form a U-shaped structure to enhance stability. The support member is connected to the baffle, so that when the support member is pulled to move, the baffle can be moved. The locking component can ensure the relative stability between the screen basket and the baffle. The diameter of the top rod is smaller than the diameter of the screen basket mesh, so as not to affect the unblocking effect of the screen basket mesh, while not causing excessive wear on the screen basket mesh. By rotating the bolt to connect it with the screw hole, the position of the support member can be locked, and the positions of the connected limiting rod and the baffle can also be locked.

[0022] 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.

[0023] Example 1

[0024] Please refer to Figure 1-6 As shown, this utility model provides an anti-clogging vibrating screen structure for a citrus sieve, including a sieve basket 1. A set of baffles 2 is provided below the sieve basket 1. A top rod 3 is installed on the upper surface of the baffles 2 corresponding to the mesh of the sieve basket 1. A set of limiting plates 4 are slidably connected to the top rod 3. The limiting plates 4 can be kept flush with the top of the top rod 3 by means of an elastic limiting component. The elastic limiting component is connected to the sieve basket 1 in conjunction with the support component.

[0025] When there is no need to clear the mesh, the elastic limiting component pushes the limiting plate 4 upward, so that its upper surface is completely flush with the top of the top rod 3. The fine impurities that are screened out, such as fiber debris and oil particles, fall onto the surface of the limiting plate 4 first, rather than falling directly into the gap between the top rods 3. Pulling the support component upward can drive the elastic limiting component, baffle 2, top rod 3 and limiting plate 4 to rise. The limiting plate 4 will first contact the bottom of the screen basket 1, and then continue to pull, so that the top rod 3 can penetrate the limiting plate 4 and insert into the mesh of the screen basket 1 to clear the blocked mesh.

[0026] Compared to existing technologies, this technology can unclog blocked mesh when needed, but during screening, it prevents screened impurities from falling directly into the gaps between the top rods 3, thus improving the convenience of impurity cleaning.

[0027] Specifically, the elastic limiting component includes limiting rods 5 and springs 6. Two sets of limiting rods 5 are installed at the extensions of both ends of the baffle 2. The limiting rods 5 are T-shaped cylindrical parts. The two sets of limiting rods 5 penetrate the extensions at the ends of the limiting plate 4 and are slidably connected to them. A set of springs 6 is sleeved at the position of each set of limiting rods 5 between the baffle 2 and the limiting plate 4. The two sets of limiting rods 5 are connected to the support.

[0028] The elastic force of spring 6 pushes the limiting plate 4 to slide upward along the top rod 3, so that its upper surface is completely flush with the top of the top rod 3. The fine impurities screened off will preferentially fall onto the surface of the limiting plate 4 instead of falling directly into the gap of the top rod 3. When the screen basket 1 vibrates, the limiting plate 4 will produce a slight shaking. The attached impurities will automatically slide off under the coupling effect of gravity and vibration. When the mesh of the screen basket 1 is blocked, the baffle 2 will be pulled up, causing the top rod 3 to move upward. The limiting plate 4 can slide down along the top rod 3 due to the limitation of the screen basket 1, and the spring 6 will be compressed. The top rod 3 can penetrate the mesh of the screen basket 1 to clear the blockage. After the top rod 3 returns to its original position, the spring 6 pushes the limiting plate 4 to be flush again, and the system resumes the screening mode.

[0029] The support includes a first support rod 7 and a second support rod 8. The top of each of the two sets of limiting rods 5 is connected to a first support rod 7. The tops of the two sets of first support rods 7 are connected to the two ends of the second support rod 8 respectively, forming a U-shaped structure. The two sets of first support rods 7 penetrate the connecting rod 9 installed at the end of the sieve basket 1 and are slidably connected to it. The support can be locked by a locking assembly, which includes bolts 10 and screw holes 11. The second support rod 8 is rotatably connected to a set of bolts 10. The bolts 10 are threadedly connected to the screw holes 11 opened in the connecting rod 9. The diameter of the top rod 3 is smaller than the diameter of the mesh of the sieve basket 1. Two sets of sliding seats 12 are symmetrically installed on both sides of the sieve basket 1.

[0030] The first support rod 7 is used to connect the top of the limiting rod 5 to the second support rod 8. The second support rod 8 and the two sets of first support rods 7 form a U-shaped structure to enhance stability. The support member is connected to the baffle 2, so that when the support member is pulled to move, the baffle 2 can be moved. The locking component can ensure the relative stability between the screen basket 1 and the baffle 2. The diameter of the top rod 3 is smaller than the diameter of the screen basket 1 mesh, so that the unblocking effect on the screen basket 1 mesh is not affected, and the screen basket 1 mesh is not excessively worn. By rotating the bolt 10 to make it threadedly connected to the screw hole 11, the position of the support member can be locked, and the positions of the connected limiting rod 5 and baffle 2 can be locked. The installed slide 12 can be used to slide the device with the slide rod in the prior art. With the reciprocating structure in the prior art, the reciprocating screening of the screen basket 1 can be realized.

[0031] Working principle: By rotating bolt 10 to connect it to screw hole 11, the position of the support component can be locked, as can the positions of the connected limiting rod 5 and baffle 2. Conversely, by unlocking, the positions of the support component and baffle 2 can be adjusted. First, the elastic force of spring 6 pushes the limiting plate 4 to slide upward along the top rod 3, so that its upper surface is completely flush with the top of the top rod 3. Fine impurities screened out preferentially fall onto the surface of the limiting plate 4, rather than falling directly into the gap of the top rod 3. When the screen basket 1 vibrates... When the limiting plate 4 vibrates slightly, the attached impurities automatically slide off under the coupling effect of gravity and vibration. When the mesh of the screen basket 1 is blocked, the locking is released, the second support rod 8 is pulled, which drives the first support rod 7 to pull the limiting rod 5, which drives the baffle 2 to rise, causing the top rod 3 to move upward. The limiting plate 4, limited by the screen basket 1, can slide down along the top rod 3, and the spring 6 is compressed. The top rod 3 can penetrate the mesh of the screen basket 1 to clear the blockage. After the top rod 3 returns to its original position, the spring 6 pushes the limiting plate 4 back to be level, and the system resumes the screening mode.
