Description

Technical Field

[0001] This application belongs to the technical field of bearing support, specifically relating to a bearing housing and a bouncing screen. Background Technology

[0002] A bouncing screen is a solid waste treatment device that sorts materials based on differences in their physical properties. It is mainly suitable for screening complex materials such as mixed household waste, aged waste, and construction waste, and it mainly uses the "bouncing" motion for sorting.

[0003] The core component of a bouncing screen is the screen bed, which includes screen plates and a drive shaft. Multiple screen plates are arranged along the axial direction of the drive shaft, and multiple eccentric wheels are arranged on the drive shaft. Each eccentric wheel corresponds to one of the screen plates. When processing solid waste, the drive shaft drives the eccentric wheels to rotate, so that the eccentric wheels drive the screen plates, causing the material on the screen plates to be periodically thrown up to produce a "bouncing" motion. This causes the movement trajectories of materials with different elasticity, coefficient of friction, and density to separate during the process. Lightweight and elastic materials (such as plastics and wood) bounce high and move forward quickly, and are discharged from the upper discharge port; while heavy, sticky, and inelastic materials (such as kitchen waste and bricks) bounce low, sink or slide along the gaps in the screen plates, and are discharged from the lower discharge port.

[0004] To increase the stability of the drive shaft, bearings and bearing housings are typically installed at both ends and along the middle of its length. The bearing housings and bearings work together to support the drive shaft, thus enhancing its stability. However, for materials with high moisture content, and during dust suppression spraying, water drips through the screen plates onto the outside of the bearing housings. This can lead to rust on the bolts, increasing the difficulty of disassembly and repair. Furthermore, water may seep into the bearings, contaminating the lubricating grease and shortening their lifespan. Additionally, flexible, strip-shaped materials may fall through the gaps between the screen plates and become entangled on the drive shaft. This can cause the material to penetrate the bearing housings and come into contact with the bearings, increasing the rotational load on the drive shaft and similarly affecting bearing lifespan. Therefore, reducing the difficulty of disassembly and repair of the bearing housings, ensuring bearing lifespan, and reducing the rotational load on the drive shaft are urgent technical challenges. Utility Model Content

[0005] This application provides a bearing housing to reduce the difficulty of disassembling and repairing the bearing housing, ensure the service life of the bearing, and reduce the rotational load on the drive shaft.

[0006] The technical solution adopted in this application is as follows:

[0007] A bearing housing includes a bearing housing body and a protective cover disposed on the bearing housing body. The protective cover has a main body section and a shaft guard section located on the side of the main body section. The main body section covers the outside of the bearing housing body from top to bottom, and the shaft guard section covers the outside of the drive shaft and is located above the drive shaft.

[0008] By adopting the above technical solution, the protective cover has a main body section and a shaft guard section located on the side of the main body section. The main body section covers the outside of the bearing housing body from top to bottom, and the shaft guard section covers the outside of the drive shaft and is located above the drive shaft. On the one hand, the main body section can protect the bearing housing body to prevent water droplets from falling onto the outside of the bearing housing body and causing bolt rust, thereby reducing the difficulty of disassembling and repairing the bearing housing body, thus facilitating the disassembly and repair of the bearing housing. On the other hand, it can also prevent water from seeping into the bearing through the bearing housing and causing the grease inside the bearing to be contaminated, thus ensuring the lubrication effect of the grease inside the bearing and thus ensuring the service life of the bearing. Furthermore, the shaft guard section can also protect the area of ​​the drive shaft near the bearing housing body to prevent falling strip-shaped materials from getting entangled in the drive shaft and intruding into the bearing housing and contacting the bearing, thereby reducing the rotational load on the drive shaft and further ensuring the service life of the bearing.

[0009] Optionally, the bearing housing body includes a base, an upper cover located above the base, and a bolt passing through the upper cover. The bolt is threadedly connected to the base. The main body section includes a lower protective portion covering the outside of the base and an upper protective portion covering the outside of the upper cover. The lower protective portion is provided with a fixing portion located between the base and the upper cover.

[0010] By adopting the above technical solution, when installing the bearing housing in this application, the base is first installed on the frame of the bouncing screen, and then the drive shaft with the bearing sleeve is installed on the base so that the bearing is located in the base. Then the lower guard is installed so that the fixing part abuts against the base, so that the base supports the lower guard. Then the upper cover is installed so that the upper cover is above the fixing part and abuts against the fixing part. Then the bolts are installed so that the upper cover and the base are fixed together. At the same time, under the action of the bolts, the base and the upper cover can squeeze the fixing part against each other to fix the lower guard, thereby increasing the stability of the lower guard and increasing the connection stability between the protective cover and the bearing housing body. Finally, the upper guard is installed so that the upper guard covers the outside of the upper cover and the bolts, thereby protecting the bolts.

[0011] Optionally, the base is provided with a connecting part for the bolt thread connection, and the fixing part is provided with a positioning part adapted to the connecting part, the positioning part being located outside the connecting part.

[0012] By adopting the above technical solution, since the fixing part is provided with a positioning part that is adapted to the connecting part, and the positioning part is located outside the connecting part, the lower guard can be positioned by the cooperation of the positioning part and the connecting part, so as to facilitate the precise installation of the lower guard. On the other hand, the lower guard can be limited by the cooperation of the positioning part and the connecting part, so as to increase the stability of the lower guard and thus increase the connection stability between the protective cover and the bearing seat body.

[0013] Optionally, the connecting portion is provided with a receiving notch, and at least a portion of the fixing portion is located in the receiving notch.

[0014] By adopting the above technical solution, since the connecting part is provided with a receiving notch, at least part of the fixing part is located in the receiving notch, thereby enabling the fixing part to avoid contact with the connecting part and the top cover, so that the top cover can completely abut against the base. This increases the connection stability between the top cover and the base on the one hand, and ensures the support and limiting effect of the bearing seat body on the bearing on the other hand.

[0015] Optionally, one bottom end of the upper protective part covers the outside of the fixing part.

[0016] By adopting the above technical solution, since the bottom end of the upper guard is covered outside the fixed part, the gap between the upper guard and the lower guard is transferred to the lower part of the fixed part. This avoids the situation where water may seep into the interior of the protective cover and contact the bolts through the gap between the upper guard and the lower guard when it flows down the upper guard, thereby improving the protective effect of the main body section on the bearing housing body and further ensuring the effect of easy disassembly and repair of the bearing housing.

[0017] Optionally, the fixing part extends outward to provide a mating part, and the bottom end of the upper protective part is provided with a snap-fit ​​part that engages with the mating part.

[0018] By adopting the above technical solution, since the fixing part extends outward and is provided with a mating part, and the bottom end of the upper guard part is provided with a snap-fit ​​part that engages with the mating part, the upper guard part can be fixedly connected to the lower guard part by using the snap-fit ​​part and the mating part. This increases the stability of the upper guard part and facilitates its installation, thereby improving the installation efficiency of the bearing housing.

[0019] Optionally, the lower guard has a side guard plate located on the side of the base and the upper cover, and the shaft guard section is connected to the side guard plate.

[0020] By adopting the above technical solution, since the lower guard has side guard plates located on the sides of the base and the upper cover, and the shaft guard section is connected to the side guard plates, the shaft guard section is integrated into the lower guard. This allows the shaft guard section to be installed at the same time as the lower guard, thereby improving the installation efficiency of the protective cover and increasing the connection stability between the shaft guard section and the bearing housing body, thus increasing the protective effect of the shaft guard section on the drive shaft.

[0021] Optionally, the upper guard portion has a side edge located on the side of the side guard plate near the shaft guard section.

[0022] By adopting the above technical solution, since the side of the upper guard is provided with an edge, which is located on the side of the side guard plate near the shaft guard section, the upper guard can be positioned and limited by the cooperation between the edge and the side guard plate, thereby increasing the connection stability between the upper guard and the lower guard and facilitating the precise installation of the upper guard. On the other hand, the gap between the upper guard and the lower guard can be shifted downward to prevent water from seeping into the interior of the protective cover through the gap between the upper guard and the lower guard and contacting the bearing housing body, thereby improving the protective effect of the protective cover on the bearing housing body and further facilitating the disassembly and repair of the bearing housing.

[0023] Optionally, the shaft guard section is provided with a baffle plate, which is located at the end of the shaft guard section away from the main body section.

[0024] By adopting the above technical solution, since the shaft guard section is equipped with a baffle plate located at the end of the shaft guard section away from the main body section, the baffle plate can be used to block the material falling into the shaft guard section, so as to prevent the material from falling onto the drive shaft at the end of the shaft guard section away from the main body section, thereby improving the protection effect of the shaft guard section on the drive shaft.

[0025] This application also provides a bouncing screen to reduce the difficulty of maintenance, the failure rate, and the energy consumption of the bouncing screen.

[0026] A bouncing screen includes a screen bed and a bearing housing as described above. The screen bed includes a screen plate and a drive shaft. The drive shaft is provided with a bearing, and the bearing housing is located outside the bearing.

[0027] By adopting the above technical solution, since the screen bed in this application uses the aforementioned bearing housing, on the one hand, it avoids the bolts of the bearing housing from easily coming into contact with water and causing the bolts to rust, thereby facilitating the disassembly and repair of the bearing housing and thus facilitating the maintenance of the bouncing screen. On the other hand, it also prevents water from seeping into the interior of the bearing and contaminating the internal lubricating grease, thus ensuring the service life of the bearing and reducing the failure rate of the bouncing screen. Furthermore, it also prevents the increased load on the drive shaft caused by strip materials entangled in it, thereby reducing the energy consumption of the bouncing screen.

[0028] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0029] 1. The bearing housing in this application includes a bearing housing body and a protective cover disposed on the bearing housing body. The protective cover has a main body section and a shaft guard section located on the side of the main body section. The main body section covers the outside of the bearing housing body from top to bottom, and the shaft guard section covers the outside of the drive shaft and is located above the drive shaft. On the one hand, the main body section can protect the bearing housing body to prevent water droplets from falling onto the outside of the bearing housing body and causing the bolts to rust, thereby reducing the difficulty of disassembling and repairing the bearing housing body, thus facilitating the disassembly and repair of the bearing housing. On the other hand, it can also prevent water from seeping into the bearing through the bearing housing and causing the grease inside the bearing to be contaminated, thereby ensuring the lubrication effect of the grease inside the bearing and thus ensuring the service life of the bearing. Furthermore, the shaft guard section can also protect the area of ​​the drive shaft near the bearing housing body to prevent falling strip-shaped materials from getting entangled in the drive shaft and intruding into the bearing housing and contacting the bearing, thereby reducing the rotational load on the drive shaft and further ensuring the service life of the bearing.

[0030] 2. The bearing housing body of this application includes a base, an upper cover located above the base, and bolts passing through the upper cover. The bolts are threadedly connected to the base. The main body section includes a lower protective part covering the outside of the base and an upper protective part covering the outside of the upper cover. The lower protective part is provided with a fixing part located between the base and the upper cover. The lower protective part can be fixedly connected to the bearing housing body by the mutual compression of the fixing part between the upper cover and the base, thereby increasing the connection stability between the lower protective part and the bearing housing body and achieving the effect of facilitating the fixing of the protective cover.

[0031] 3. The base in this application is provided with a connecting part for bolt thread connection, and the fixing part is provided with a positioning part adapted to the connecting part. The positioning part is located outside the connecting part. Thus, on the one hand, the lower guard can be positioned by the cooperation between the positioning part and the connecting part, so as to facilitate the precise installation of the lower guard. On the other hand, the lower guard can be limited by the cooperation between the positioning part and the connecting part, so as to increase the stability of the lower guard, thereby increasing the connection stability between the protective cover and the bearing seat body.

[0046] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0048] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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, an electrical connection, or a communication 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 application according to the specific circumstances.

[0050] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0051] Reference Figures 1 to 9 A bearing housing is disclosed, which includes a bearing housing body 1 and a protective cover 2 disposed on the bearing housing body 1. The protective cover 2 has a main body section 21 and a shaft guard section 22 located on the side of the main body section 21. The main body section 21 covers the outside of the bearing housing body 1 from top to bottom, and the shaft guard section 22 covers the outside of the drive shaft 4 and is located above the drive shaft 4.

[0052] It is understandable that the shaft guard section 22 is located above the drive shaft 4, thereby protecting the drive shaft 4 to prevent strip materials from falling onto the drive shaft 4 and getting tangled in it. There is also a gap between the shaft guard section 22 and the drive shaft 4 to prevent the load on the drive shaft 4 from increasing due to the installation of the shaft guard section 22.

[0053] It should be noted that the above-mentioned "main body section 21 is covered outside the bearing housing body 1 from top to bottom" means that the main body section 21 is installed on the bearing housing body 1 in the direction from top to bottom, and the main body section 21 can block materials or water falling from top to bottom so that the materials or water falling from top to bottom cannot directly contact the bearing housing body 1, thereby achieving isolation between the materials or water and the bearing housing.

[0054] Since the protective cover 2 has a main body section 21 and a shaft guard section 22 located on the side of the main body section 21, the main body section 21 covers the outside of the bearing housing body 1 from top to bottom, and the shaft guard section 22 covers the outside of the drive shaft 4 and is located above the drive shaft 4, the main body section 21 can protect the bearing housing body 1 to prevent water droplets from falling onto the outside of the bearing housing body 1 and causing the bolts 13 to rust, thereby reducing the difficulty of disassembling and repairing the bearing housing body 1 and making it easier to disassemble and repair the bearing housing. On the other hand, it can also prevent water from seeping into the bearing through the bearing housing and causing the grease inside the bearing to be contaminated, so as to ensure the lubrication effect of the grease inside the bearing and thus ensure the service life of the bearing. Furthermore, the shaft guard section 22 can also protect the drive shaft 4 near the bearing housing body 1 to prevent falling strip-shaped materials from getting entangled in the drive shaft 4 and invading the bearing housing and contacting the bearing, thereby reducing the rotational load of the drive shaft 4 and further ensuring the service life of the bearing.

[0055] This application does not specify the number of axle guard sections 22; preferably, refer to... Figures 1 to 3 The shaft guard section 22 is provided in two sections, which are located on opposite sides of the main body section 21. That is, the two shaft guard sections 22 are located on opposite sides of the main body section 21 along the axial direction of the drive shaft 4, so that the two shaft guard sections 22 can protect the part of the drive shaft 4 located on both sides of the bearing housing body 1, thereby improving the protection effect of the drive shaft 4. In other embodiments, the shaft guard section 22 may also be provided in only one section, and the shaft guard section 22 may be located on one side of the main body section 21.

[0056] This application does not specify a particular method for fixing the protective cover 2; preferably, refer to... Figures 1 to 9 The bearing housing body 1 includes a base 11, an upper cover 12 located above the base 11, and a bolt 13 passing through the upper cover 12. The bolt 13 is threadedly connected to the base 11. The main body section 21 includes a lower protective part 211 covering the outside of the base 11 and an upper protective part 212 covering the outside of the upper cover 12. The lower protective part 211 is provided with a fixing part 213 located between the base 11 and the upper cover 12.

[0057] Understandably, the upper cover 12 is provided with a hole structure for the bolt 13 to pass through, and the base 11 is provided with a threaded hole for the bolt 13 to be threaded. After the bolt 13 is installed on the upper cover 12 and the base 11, the bolt head of the bolt 13 abuts against the upper cover 12 and applies downward pressure to the upper cover 12, so that the upper cover 12 and the base 11 squeeze the fixing part 213; the interior of the lower cover 211 forms a space to accommodate the base 11, and the interior of the upper cover 212 forms a space to accommodate the upper cover 12.

[0058] When installing the bearing housing in this application, first install the base 11 onto the frame 5 of the bouncing screen, then install the drive shaft 4 with the bearing mounted on it onto the base 11 so that the bearing is located in the base 11. Next, install the lower guard 211 so that the fixing part 213 abuts against the base 11, thereby using the base 11 to support the lower guard 211. Then, install the upper cover 12 so that it is located above and abuts against the fixing part 213. Finally, install the bolts 13 to utilize... Bolt 13 fixes the upper cover 12 and the base 11 together. At the same time, under the action of bolt 13, the base 11 and the upper cover 12 can press the fixing part 213 against each other to fix the lower guard part 211, thereby increasing the stability of the lower guard part 211 and increasing the connection stability between the protective cover 2 and the bearing seat body 1. Finally, the upper guard part 212 is installed so that the upper guard part 212 covers the outside of the upper cover 12 and the bolt 13, thereby protecting the bolt 13.

[0059] This application does not specifically limit the structure of the fixing part 213; preferably, refer to... Figure 5 and Figure 8 The fixing part 213 is a sheet-like structure located on the top of the lower cover 211, and it forms the top wall of the lower cover 211. The fixing part 213 has a groove-shaped structure for the bolt 13 to pass through, ensuring that the bolt 13 can pass through the fixing part 213 and be threaded onto the base 11. It also increases the connection area between the fixing part 213, the upper cover 12, and the base 11, thereby increasing the stability of the lower cover 211. In other embodiments, the fixing part 213 can also be other structures, such as a rib structure located inside the lower cover 211.

[0060] Furthermore, refer to Figure 4 and Figure 5 The base 11 is provided with a connecting part 111 for threaded connection of bolt 13, and the fixing part 213 is provided with a positioning part 214 adapted to the connecting part 111. The positioning part 214 is located outside the connecting part 111.

[0061] It is understandable that the threaded hole is provided in the connecting part 111, the positioning part 214 is located at the bottom of the fixing part 213, and the inner contour of the positioning part 214 is the same as the outer contour of the connecting part 111. After the lower guard 211 is installed on the base 11, the inner wall of the positioning part 214 abuts against the outer wall of the connecting part 111.

[0062] Since the fixing part 213 is provided with a positioning part 214 that is adapted to the connecting part 111, and the positioning part 214 is located outside the connecting part 111, the lower guard 211 can be positioned by the cooperation between the positioning part 214 and the connecting part 111, so as to facilitate the precise installation of the lower guard 211. On the other hand, the lower guard 211 can be limited by the cooperation between the positioning part 214 and the connecting part 111, so as to increase the stability of the lower guard 211, thereby increasing the connection stability between the protective cover 2 and the bearing seat body 1.

[0063] This application does not specifically limit the structure of the connecting part 111 and the positioning part 214. Preferably, the connecting part 111 is a block structure with a semi-circular cross-section that protrudes outward from the side of the base 11, and the positioning part 214 is an arc-shaped sheet structure that is fixedly connected to the fixing part 213 and has the same cross-sectional shape as the connecting part 111. This simplifies the structural design of the connecting part 111 and the positioning part 214, thereby facilitating the manufacturing of the bearing housing. In other embodiments, the connecting part 111 and the positioning part 214 can also be structures with other cross-sectional shapes.

[0064] Furthermore, refer to Figure 4 and Figure 5 The connecting part 111 is provided with a receiving notch, and at least a portion of the fixing part 213 is located in the receiving notch.

[0065] It is understandable that the height of the receiving notch is equal to the thickness of the fixing part 213, so that after the lower guard 211 is installed on the base 11, the top end face of the fixing part 213 is flush with the top end face of the base 11.

[0066] Since the connecting part 111 is provided with a receiving notch, at least part of the fixing part 213 is located in the receiving notch, thereby enabling the fixing part 213 to avoid the connecting part 111 and the upper cover 12, so that the upper cover 12 can completely abut against the base 11. This increases the connection stability between the upper cover 12 and the base 11, and ensures the support and limiting effect of the bearing seat body 1 on the bearing.

[0067] Furthermore, refer to Figure 4 and Figure 5 The bottom end of the upper protective part 212 is covered outside the fixing part 213.

[0068] It is understandable that the bottom end of the upper guard 212 overlaps with the fixing part 213 in the vertical direction, that is, the bottom end of the upper guard 212 can completely cover the fixing part 213.

[0069] Since the bottom end of the upper protective part 212 is covered outside the fixed part 213, the gap between the upper protective part 212 and the lower protective part 211 is transferred to the lower part of the fixed part 213. This prevents water from flowing down the upper protective part 212 and possibly seeping into the interior of the protective cover 2 through the gap between the upper protective part 212 and the lower protective part 211 and contacting the bolt 13. This improves the protective effect of the main body section 21 on the bearing housing body 1 and further ensures that the bearing housing can be easily disassembled and repaired.

[0070] This application does not specify the connection method between the upper protective part 212 and the lower protective part 211. Preferably, refer to... Figure 5 and Figure 8 The fixing part 213 extends outward and is provided with a mating part 215. The bottom end of the upper guard 212 is provided with a snap-fit ​​part 218 that engages with the mating part 215.

[0071] Understandably, the snap-fit ​​part 218 is located at one end of the bottom of the upper cover 212, near the fixing part 213.

[0072] Since the fixing part 213 extends outward and is provided with a mating part 215, and the bottom end of the upper guard 212 is provided with a snap-fit ​​part 218 that engages with the mating part 215, the upper guard 212 can be fixedly connected to the lower guard 211 by using the snap-fit ​​part 218 and the mating part 215. This increases the stability of the upper guard 212 and facilitates the installation of the upper guard 212, thereby improving the installation efficiency of the bearing housing.

[0073] This application does not specifically limit the structure of the mating part 215 and the snap-fit ​​part 218. Preferably, refer to Figure 5 and Figure 8 The mating part 215 is a mating piece extending outward from the fixing part 213, and the snap-fit ​​part 218 is a snap-fit ​​piece fixedly connected to the inner side of one bottom end of the upper cover 212. The snap-fit ​​piece is inclined from bottom to top toward the side where the fixing part 213 is located, and the snap-fit ​​piece can elastically swing relative to the upper cover 212 under the action of extrusion force, so that when the upper cover 212 is installed in the direction from top to bottom, the snap-fit ​​piece can guide the upper cover 212, and at the same time, it can also achieve the effect of making the snap-fit ​​piece elastically deform and pass over the mating piece to snap-fit ​​together with the mating piece, so as to facilitate the installation of the upper cover 212. In other implementation examples, the mating part 215 may also be a hole structure provided in the fixing part 213 or the lower guard 211, and the snap-fit ​​part 218 may be an arm body provided inside the upper guard 212 with an L-shaped cross-section, so as to realize the snap-fit ​​mating between the upper guard 212 and the lower guard 211 by using the mating of the arm body and the hole structure.

[0074] Of course, in other embodiments, the upper protective part 212 can also be connected to the lower protective part 211 by means of adhesive bonding, interference fit, or other methods.

[0075] This application does not specify the installation method of the shaft guard section 22; preferably, refer to... Figure 3 , Figure 6 , Figure 7 and Figure 9 The lower guard 211 has a side guard plate 216 located on the side of the base 11 and the upper cover 12, and the shaft guard section 22 is connected to the side guard plate 216.

[0076] It is understood that there are two side guard plates 216 spaced apart, and the shaft guard section 22 is arranged one-to-one with the side guard plate 216. Each shaft guard section 22 is fixedly connected to its corresponding side guard plate 216 so as to integrate the shaft guard section 22 into the lower guard section 211. The side guard plate 216 is provided with a clearance notch to accommodate the drive shaft 4 so that the lower guard section 211 can be installed on the outside of the base 11 from top to bottom.

[0077] Since the lower guard 211 has a side guard plate 216 located on the side of the base 11 and the upper cover 12, and the shaft guard section 22 is connected to the side guard plate 216, the shaft guard section 22 is integrated into the lower guard 211. This allows the shaft guard section 22 to be installed at the same time as the lower guard 211 is installed, thereby improving the installation efficiency of the protective cover 2 and increasing the connection stability between the shaft guard section 22 and the bearing housing body 1, thus increasing the protective effect of the shaft guard section 22 on the drive shaft 4.

[0078] In other embodiments, the shaft guard section 22 can be fixedly connected to the upper guard section 212 to integrate the shaft guard section 22 into the upper guard section 212, thereby achieving the installation of the shaft guard section 22 while installing the upper guard section 212.

[0079] Furthermore, refer to Figure 6 , Figure 7 and Figure 9 The upper guard 212 has a side edge 219 on its side, which is located on the side of the side guard plate 216 near the shaft guard section 22.

[0080] It is understandable that the upper guard 212 has edges 219 on both sides opposite to each other, and the two edges 219 are located on the opposite sides of the two side guards 216.

[0081] Because the upper guard 212 has an edge 219 on its side, which is located on the side of the side guard plate 216 near the shaft guard section 22, the edge 219 and the side guard plate 216 can cooperate to position and limit the upper guard 212, thereby increasing the connection stability between the upper guard 212 and the lower guard 211 and facilitating the precise installation of the upper guard 212. On the other hand, it can also shift the gap between the upper guard 212 and the lower guard 211 downwards to prevent water from seeping into the interior of the protective cover 2 through the gap between the upper guard 212 and the lower guard 211 and contacting the bearing housing body 1, thereby improving the protective effect of the protective cover 2 on the bearing housing body 1 and further facilitating the disassembly and repair of the bearing housing.

[0082] The better one is to refer to Figure 5 and Figure 8 The upper guard 212 is composed of a plate-like structure with an inverted U-shaped cross-section, so that materials falling onto the upper guard 212 can slide down along the outer contour of the upper guard 212, thereby preventing materials from accumulating on the outside of the protective cover 2.

[0083] The better one is to refer to Figure 3 , Figure 7 and Figure 8 The lower guard 211 also has a protective plate 217 located between the two side guards 216, and the protective plate 217 is fixedly connected to the two side guards 216. The fixing part 213 is fixedly connected to the top of the protective plate 217, so that the protective plate 217, the side guards 216 and the fixing part 213 together form the space for accommodating the base 11. At the same time, the cross-sectional shape of the protective plate 217 is arc-shaped, so that the material sliding down along the upper guard 212 can continue to slide down along the protective plate 217, so that the material eventually falls off the protective cover 2.

[0084] In other embodiments, the protective cover 2 can also be connected to the bearing housing body 1 by means of adhesive bonding, interference fit, or other methods.

[0085] In a preferred embodiment, refer to Figure 1 and Figure 2 The shaft protection section 22 is provided with a baffle 221, which is located at the end of the shaft protection section 22 away from the main body section 21.

[0086] It is understood that the baffle 221 is fixedly connected to the shaft guard section 22, and the baffle 221 is located at the top of the shaft guard section 22.

[0087] Since the shaft guard section 22 is equipped with a baffle 221, which is located at the end of the shaft guard section 22 away from the main body section 21, the baffle 221 can block the material falling into the shaft guard section 22, so as to prevent the material from falling onto the drive shaft 4 at the end of the shaft guard section 22 away from the main body section 21, thereby improving the protection effect of the shaft guard section 22 on the drive shaft 4.

[0088] This application does not impose specific limitations on the installation method of the baffle 221. Preferably, the baffle 221 is set perpendicular to the shaft guard section 22 to reduce the manufacturing difficulty of the protective cover 2.

[0089] In other embodiments, both baffles 221 are inclined and the distance between the two baffles 221 gradually increases from bottom to top, so that the baffles 221 can guide the material falling from the top of the shaft guard section 22, so that the material falls from the inside of the baffles 221, thereby further preventing the material from falling onto the drive shaft 4.

[0090] This application does not specifically limit the structure of the shaft guard section 22. Preferably, the shaft guard section 22 is a plate-like structure with an inverted U-shaped cross-section that is fixedly connected to the side guard plate 216. This allows the protective cover 2 to be installed on the outside of the bearing housing body 1 from top to bottom. It also allows materials falling onto the shaft guard section 22 to automatically slide down along it, preventing material accumulation at the top of the shaft guard section 22. In other embodiments, the shaft guard section 22 can also be a flat plate or other material that provides protection for the drive shaft 4.

[0091] Reference Figure 10 and Figure 11 This application also discloses a bouncing screen, which includes a screen bed and a bearing housing as described above. The screen bed includes a screen plate 3 and a drive shaft 4. The drive shaft 4 is provided with a bearing, and the bearing housing is located outside the bearing.

[0092] Because the screen bed in this application uses the aforementioned bearing housing, it avoids the situation where the bolts 13 of the bearing housing are easily exposed to water and thus rusts, thereby facilitating the disassembly and repair of the bearing housing and the maintenance of the bouncing screen. On the other hand, it also prevents water from seeping into the bearing and contaminating the internal grease, thus ensuring the service life of the bearing and reducing the failure rate of the bouncing screen. Furthermore, it also prevents the increased load on the drive shaft 4 caused by strip materials entangled in it, thereby reducing the energy consumption of the bouncing screen.

[0093] Preferably, the bouncing screen also includes a frame 5, with multiple bearings spaced apart along the axial direction of the drive shaft 4. Each bearing has a bearing housing on its exterior, and each bearing housing is fixedly connected to the frame 5. Two bearings are located at the two ends of the drive shaft 4, and the remaining bearings are located in the middle of the drive shaft 4 along its length. The multiple bearing housings located in the middle of the drive shaft 4 along its length all use the improved bearing housings described above, while the bearing housings located at the ends of the drive shaft 4 can use ordinary bearing housings.
