Description

Technical Field

[0001] This invention relates to the field of screen anti-clogging technology, and in particular to screen striking devices and screening devices. Background Technology

[0002] Screening devices are widely used in industries such as mining and waste treatment due to their reliable structure, strong vibration force, and high screening efficiency. However, during the screening process, some small-diameter materials may be adsorbed into the gaps in the screen mesh. Over time, this can lead to material accumulation, causing screen blockage, which in turn affects screening efficiency, reduces the service life of the screen, and increases production and maintenance costs.

[0003] Existing technologies also include some screen beating devices to prevent screen clogging. However, the position and number of the beating elements in these devices are fixed. When the screen is screening materials that are not prone to clogging, if the number of beating elements cannot be reduced or the position of the beating elements cannot be adjusted, it will result in waste of the beating elements, and repeated use of the beating elements will easily damage them. When the screen is more prone to clogging, if the number of beating elements cannot be increased or the position of the beating elements cannot be adjusted, it will lead to poor screen unblocking effect.

[0004] Therefore, the existing screen striking devices have low flexibility and cannot adjust the number and position of striking parts according to the actual working conditions of the screen, resulting in poor versatility.

[0005] Therefore, there is an urgent need for a new screen striking device and screen to solve the problems of the inability to adjust the position and number of striking parts, low flexibility of use, and poor versatility. Summary of the Invention

[0006] One object of the present invention is to provide a screen striking device that can adapt to different working conditions of the screen and has high flexibility and versatility.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The screen striking device includes:

[0009] Base plate, the base plate being used for mounting on the screen;

[0010] At least two bases are disposed on the base plate and arranged at intervals along a first preset direction; the number of bases is adjustable and the distance between two adjacent bases is adjustable; and

[0011] A striking component, which is rotatably connected to the base.

[0012] As a preferred embodiment of the screen striking device, the base includes:

[0013] The base body, the striking component is rotatably connected to the base body, and the relative position of the base body relative to the base plate along the first preset direction is adjustable;

[0014] The first fastener is used to fix the base body to the base plate.

[0015] As a preferred embodiment of the screen striking device, the base body includes:

[0016] A lower seat, wherein the lower seat is disposed on the base plate, and a first receiving groove is formed on the upper surface of the lower seat, the first receiving groove extending downward from the upper surface of the lower seat; and

[0017] The upper seat is located above the lower seat. A second receiving groove is formed on the lower surface of the upper seat. The second receiving groove extends upward from the lower surface of the upper seat. The first receiving groove and the second receiving groove are opposite each other and together form a receiving hole. The striking member is received in the receiving hole.

[0018] As a preferred embodiment of the screen striking device, the cross-sectional area of ​​the lower seat gradually increases from top to bottom.

[0019] As a preferred embodiment of the screen striking device, the striking element includes:

[0020] A connecting portion, rotatably connected to the base, the connecting portion extending along a second preset direction and extending beyond both sides of the base, wherein the first preset direction is different from the second preset direction; and

[0021] A striking part is provided at the free end of the connecting part, and the connecting part and the striking part are set at an obtuse angle.

[0022] As a preferred embodiment of the screen striking device, the striking element further includes:

[0023] A limiting part is provided, which is connected to the connecting part and cooperates with the base to limit the extreme position of the rotation of the striking member.

[0024] As a preferred embodiment of the screen striking device, the striking part includes:

[0025] The striking part body is fixedly connected to the connecting part; and

[0026] A protective layer is disposed on the outside of the striking part body.

[0027] As a preferred embodiment of the screen striking device, the striking part further includes:

[0028] The second fastener secures the protective layer and the striking part body together.

[0029] As a preferred embodiment of the screen striking device, the protective layer is made of a flexible material.

[0030] Another objective of this invention is to provide a screening device that can adapt to different working conditions and is highly flexible and versatile.

[0031] A screening device includes a screen and a screen striking device as described above, the screen striking device being installed on the screen.

[0032] Beneficial effects:

[0033] This invention provides a screen striking device. The device rotatably mounts striking components within a base, allowing them to rotate with the vibration of the screen. These components continuously strike the screen, clearing blockages and preventing clogging. Furthermore, the number and position of the base and striking components can be adjusted according to the actual screen usage, offering high flexibility. When the screen is easy to clear, the number of bases and striking components can be reduced, and their installation positions adjusted to increase the distance between adjacent striking components, minimizing wear on the striking components while maintaining effective clearing. Conversely, when the screen is difficult to clear, the number of bases and striking components can be increased, and their installation positions adjusted to decrease the distance between adjacent striking components, thus ensuring effective clearing. Therefore, this screen striking device offers high versatility.

[0034] The present invention also provides a screening device that uses the above-mentioned screen striking device to strike the screen, which can clear the screen and prevent the screen from clogging. At the same time, the screening device has high versatility. Attached Figure Description

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0044] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0047] The following section describes the basic structure, working process, and effects of a screening device, using a screening scenario as an example. A screening device consists of a screen and a vibrating mechanism. The vibrating mechanism generates vibration, which in turn causes the screen to vibrate. The material to be screened is located on the screen. When the screen vibrates, the screening device allows materials smaller than the screen openings to pass through, while particles larger than the openings remain on the screen surface, thus completing the screening of the material.

[0048] During the material screening process, the screen mesh is easily clogged due to material accumulation. To solve this problem, this disclosure provides a screen striking device that can clear clogged screens. This disclosure also provides a screening device including a screen and a screen striking device, with the striking device installed on the screen. This screening device utilizes the screen striking device to clear the screen, preventing clogging, and is highly versatile.

[0049] like Figure 1 As shown, the screen striking device provided in this embodiment includes a base plate 1, at least two bases 2, and striking elements 3. The base plate 1 is installed on the screen, and the at least two bases 2 are disposed on the base plate 1 and arranged at intervals along the front-back direction (i.e., a first preset direction). The striking elements 3 are rotatably connected to the bases 2. After the screen is installed, when the screen vibrates, it will drive the striking elements 3 to rotate within the bases 2. During the rotation, the striking elements 3 will continuously strike the screen, thereby clearing the screen and preventing it from becoming clogged.

[0050] However, during the use of the screen, if the screen is screening materials that are not prone to clogging, if the number of striking parts 3 is not reduced or the position of striking parts 3 is not adjusted, it will result in the waste of striking parts 3, and repeated use will easily lead to damage to striking parts 3; when the screen is more prone to clogging, if the number of striking parts 3 is not increased or the position of striking parts 3 is not adjusted, it will result in poor unblocking effect of the screen.

[0051] To solve the above problems, such as Figure 1 As shown in the embodiments of this disclosure, the number of bases 2 of the screen striking device is adjustable, and the distance between two adjacent bases 2 is also adjustable. When the screen is easy to clear, the number of bases 2 and striking elements 3 can be reduced, while the distance between two adjacent sets of bases 2 and striking elements 3 can be increased. This reduces the wear and tear on the bases 2 and striking elements 3, thus lowering the operating cost, while ensuring the screen clearing effect. When the screen is difficult to clear, the number of bases 2 and striking elements 3 can be increased, while the distance between two adjacent sets of bases 2 and striking elements 3 can be decreased, thereby ensuring the screen clearing effect and ensuring that the material can be effectively screened. This screen striking device offers greater flexibility in use.

[0052] like Figure 1As shown, the base 2 includes a base body 21 and a first fixing member 22. The striking member 3 is rotatably connected to the base body 21. The relative position of the base body 21 to the base plate 1 in the front-rear direction is adjustable. The first fixing member 22 is used to fix the base body 21 to the base plate 1. By setting the first fixing member 22, the base 2 and the base plate 1 can be easily and quickly assembled and disassembled. Specifically, the first fixing member 22 can be a screw, pin, or bolt and nut assembly. The structure of the first fixing member 22 is simple and can realize the quick assembly and disassembly of the base 2 and the base plate 1. Of course, all first fixing members 22 that can realize the fixing function are within the protection scope of the embodiments of this disclosure.

[0053] Specifically, such as Figure 1 As shown, the base plate 1 has multiple light holes along the front-to-back direction, and the base body 21 also has light holes. The first fixing member 22 is a bolt and nut assembly. The bolt passes through two light holes, and the nut is tightened on the bolt, thereby fixing the base body 21 and the base plate 1 together. When it is necessary to reduce the number of base bodies 21 installed, the nut is loosened, the bolt is removed from the two light holes, and the base body 21 is removed from the base plate 1. When it is necessary to increase the number of base bodies 21 installed, the bolt is passed through the two light holes and the nut is tightened to install the base body 21 onto the base plate 1. When it is necessary to adjust the distance between adjacent base bodies 21, the base body 21 is removed from the base plate 1, a new light hole is selected at another position on the base plate 1, and then the bolt and nut assembly is used to install the base body 21 onto the base plate 1. In other embodiments, threaded holes can be opened on the base plate 1 and the base 2, and the first fixing member 22 is a screw, which can also be used to adjust the number and position of the striking parts 3.

[0054] like Figure 1 and Figure 2As shown, the base body 21 includes an upper seat 212 and a lower seat 211 from top to bottom. The lower seat 211 is disposed on the base plate 1. A first receiving groove 2111 is formed on the upper surface of the lower seat 211, extending downward from the upper surface of the lower seat 211. A second receiving groove 2121 is formed on the lower surface of the upper seat 212, extending upward from the lower surface of the upper seat 212. The first receiving groove 2111 and the second receiving groove 2121 are opposite each other and together form a receiving hole in which the striking member 3 is received. The base body 21 adopts a split design, which makes it easier to quickly assemble the base 2 and the striking member 3. Moreover, when the base body 21 is damaged, only the damaged upper seat 212 or lower seat 211 needs to be replaced, without replacing the entire base body 21, thus reducing the usage cost of the base body 21. Meanwhile, the thickness of the upper seat 212 and the lower seat 211 is 5mm to 30mm. The striking element 3 is located between the upper seat 212 and the lower seat 211. The upper seat 212 and the lower seat 211 can protect the striking element 3. The striking element 3 will be subjected to a large oscillation force during the striking of the screen. At this time, the base body 21 can effectively prevent the striking element 3 from disconnecting from the base body 21 under the action of the oscillation force, thereby increasing the durability of the screen striking device and extending its service life.

[0055] Specifically, such as Figure 1 and Figure 2 As shown, the cross-section of the receiving hole is circular, and the corresponding cross-section of the striking element 3 is also circular. The circular cross-section makes the rotation of the striking element 3 in the receiving hole smoother, and makes the striking element 3 rotate more smoothly with the vibration of the screen, thus improving the unblocking effect of the screen.

[0056] In addition, such as Figure 1 and Figure 2 As shown, the cross-sectional area of ​​the lower seat 211 gradually increases from top to bottom. This design can increase the structural strength of the lower seat 211 and make it less prone to damage during use.

[0057] Combination Figure 1 and Figure 3 The structure of the striking component 3 is described below. The striking component 3 includes a connecting part 32 and a striking part 31. The connecting part 32 is rotatably connected to the base 2. The connecting part 32 extends in the left-right direction (i.e., the second preset direction) and extends out of both sides of the base 2. The front-back direction is different from the left-right direction. The striking part 31 is disposed at the free end of the connecting part 32. The connecting part 32 and the striking part 31 are set at an obtuse angle. The striking component 3 with the obtuse angle can strike the screen more effectively and has a better unblocking effect on the screen.

[0058] Furthermore, the striking component 3 is made of steel pipe. Steel has high strength and hardness, thus it can deliver a more powerful impact on the screen, ensuring effective unblocking of the drying mesh. At the same time, the tubular striking component 3 is lighter and easier to rotate and strike under the vibration of the screen, resulting in a higher number of effective strikes.

[0059] When the screen is prone to clogging, the number of striking elements 3 will increase, and the distance between adjacent striking elements 3 will decrease. During the striking process, adjacent striking elements 3 may interfere with each other, which will affect the unblocking effect on the screen.

[0060] To solve the above problems, such as Figure 1 , Figure 3 and Figure 4 As shown, the striking element 3 also includes a limiting part 33, which is connected to the connecting part 32. The limiting part 33 cooperates with the base 2 to limit the extreme position of the striking element 3's rotation. When the striking element 3 rotates to a certain angle, the limiting part 33 can cooperate with the base 2, preventing the striking element 3 from continuing to rotate, thereby avoiding interference between adjacent striking elements 3 and ensuring the unblocking effect of the screen.

[0061] Specifically, such as Figure 1 and Figure 4 As shown, the length of the lower surface of the upper seat 212 in the left-right direction is less than the length of the upper surface of the lower seat 211 in the left-right direction, and the center lines of the upper seat 212 and the lower seat 211 are aligned in the front-back direction. The limiting part 33 is located above the lower seat 211 and outside the upper seat 212 in the left-right direction. Therefore, when the striking member 3 rotates to a certain angle, the limiting part 33 will abut against the upper surface of the lower seat 211, and the lower seat 211 will block the limiting part 33 from continuing to rotate, thereby preventing the striking member 3 from continuing to rotate.

[0062] like Figure 1 and Figure 3 As shown, the striking part 31 includes a striking part body 311 and a protective layer 312. The striking part body 311 is fixedly connected to the connecting part 32, and the protective layer 312 is disposed on the outer side of the striking part body 311. The protective layer 312 can protect the striking part body 311 and the screen, making the striking part body 311 and the screen less prone to deformation or damage, thereby extending the service life of the striking part 311 and the screen.

[0063] In addition, such as Figure 1 and Figure 3 As shown, the striking part 31 also includes a second fixing member 313, which connects the protective layer 312 and the striking part body 311. The second fixing member 313 can increase the connection strength between the protective layer 312 and the striking part body 311, and prevent the protective layer 312 and the striking part body 311 from separating during the striking process.

[0064] Specifically, the striking part body 311 has a fixing hole 3111, and the protective layer 312 has a second connecting hole. A second fixing member 313 passes through the second connecting hole and the fixing hole 3111 to connect the protective layer 312 and the striking part body 311. The second fixing member 313 can be a screw or a pin for easy assembly and disassembly. Of course, all second fixing members 313 that can realize the connection function are within the protection scope of the embodiments of this disclosure.

[0065] Furthermore, the protective layer 312 is made of a flexible material. The flexible material of the protective layer 312 is more wear-resistant, has a longer service life, and can reduce the impact force of the striking part body 311 on the screen, thus providing better protection for the screen. In addition, the flexible material of the protective layer 312 can also effectively reduce the noise generated by the impact on the screen. Specifically, the material of the protective layer 312 can be rubber, silicone, or felt, etc., and all other flexible materials are within the protection scope of the embodiments of this disclosure.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
