[0025] As Figures 1 to 2 The utility model discloses a high polymer material conveying wheel waterproof seat wear -resisting cover, including fixed seat 1 and wear -resisting cover 2,

[0026] Fixed seat 1 is provided with first fixed groove 11, second fixed groove 12 and fixed part 13;

[0027] Wear -resisting cover 2 is provided with first fixed part 21 and second fixed part 22, and first fixed part 21 and second fixed part 22 are integrally formed, and first fixed part 21 is rotationally frictionally connected with the axle rod of the high polymer material conveying wheel.

[0028] Fixed part 13 is fixed through first fixed groove 11, and second fixed part is fixed through second fixed groove 12, and fixed part 13 is connected with fixed seat 1 and is used for pressing the edge of second fixed part 22.

[0029] First fixed part 21 and second fixed part 22 of wear -resisting cover 2 are integrally formed, and rotationally frictionally connected with the axle rod of the high polymer material conveying wheel, and the design significantly improves the wear resistance of the contact surface and prolongs the service life of the equipment.

[0030] Through the setting of first fixed groove 11, second fixed groove 12 and fixed part 13, wear -resisting cover 2 can be stably installed on fixed seat 1, and fixed part 13 can also press the edge of second fixed part 22, to ensure the firmness and stability of installation. This design simplifies the installation process, and also facilitates subsequent maintenance and replacement.

[0031] Waterproof seat wear -resisting cover 2 can be directly used in humid environment, has good corrosion resistance and water resistance, improves the stability of the rotation of the high polymer material conveying wheel.

[0032] When using, the integrally formed structure and wear -resisting characteristics of wear -resisting cover 2 can keep a low wear rate in the friction process with the axle rod of the high polymer material conveying wheel. At the same time, through the accurate slot design and the use of fixed part 13, the stable installation of wear -resisting cover 2 on fixed seat 1 is ensured, so that the multiple effects of wear resistance, waterproof and easy maintenance are realized.

[0033] The length of first fixed part 21 is less than the depth of first fixed groove 11, so that first fixed part 21 is kept in first fixed groove 11.

[0034] Preferably, the outer side of first fixed part 21 is provided with a rough surface, which increases the friction area between the outer side of first fixed part 21 and the inner wall of first fixed groove 11, so that first fixed part 21 is not easy to rotate in first fixed groove 11.

[0035] The inner side of the first fixing part 21 is provided with a circumferential groove, which reduces the area and friction of the inner side of the first fixing part 21 with the shaft of the polymer material conveying wheel.

[0036] The wear-resistant sleeve 2 is a self-lubricating wear-resistant sleeve 2 made of good wear-resistant and corrosion-resistant materials such as ferritic stainless steel, copper alloy, engineering plastic alloy MGA or polyether ether ketone PEEK, etc.

[0037] As shown in the drawings, the top of the fixed seat 1 is provided with a connecting table 14, and the side of the fixed seat 1 is provided with a connecting groove 15. A variety of connection methods are provided through the connecting table 14 and the connecting groove 15 to fix the fixed seat 1, which is more easily disassembled and installed when maintenance and replacement are needed. Figure 2 The included angle a between the connecting table 14 and the top end face of the fixed seat 1 is 90°-120°. By designing the included angle a to be 90°-120°, this range helps to optimize stress distribution. When subjected to external force, the included angle a can guide the stress to be more evenly distributed on the connecting table 14, thereby reducing the risk of stress concentration and local wear. This design improves the overall durability and service life of the wear-resistant sleeve 2 and the fixed seat 1.

[0038] Specifically, the included angle a can be 90°, 100°, 110° or 120°, and the present embodiment takes the included angle a as 90° as an example.

[0039] As shown in the drawings, the connecting table 14 of the present embodiment is provided with a first connecting hole 141 from top to bottom, and the first connecting hole 141 is in communication with the first fixing groove 11.

[0040] Figure 2 The first connecting hole 141 allows the use of fasteners such as bolts 144, pins, etc. to directly pass through the connecting table 14 and connect with the first fixing part 21 of the wear-resistant sleeve 2 in the first fixing groove 11. This design not only simplifies the installation process and reduces the number of parts required, but also significantly improves the connection efficiency and strength, ensuring a stable connection between the wear-resistant sleeve 2 and the fixed seat 1.

[0041] Through the communication of the first connecting hole 141 and the first fixing groove 11, stress can be more smoothly transmitted from the wear-resistant sleeve 2 to the fixed seat 1, avoiding the risk of stress concentration and local damage. This design helps to disperse and balance the stress, improving the stability and durability of the overall structure.

[0042] As shown in the drawings, one side of the connecting table 14 of the present embodiment is provided with a second connecting hole 142, and the second connecting hole 142 is in communication with the first connecting hole 141.

[0043] As shown in the drawings, one side of the connecting table 14 of the present embodiment is provided with a second connecting hole 142, and the second connecting hole 142 is in communication with the first connecting hole 141. Figure 2 ​​

[0044] The first connecting hole 141 and the second connecting hole 142 are in communication, forming a stress transmission channel, so that stress can be more smoothly transmitted from the wear-resistant sleeve 2 to the fixing seat 1. This design helps to optimize stress distribution and reduce local stress concentration, thereby improving the overall strength and durability of the equipment.

[0045] By interfering with the fastener in the first connecting hole 141 through different fasteners or connecting pieces 31 such as bolts 144, pins, buckles, etc., the fastener in the first connecting hole 141 is prevented from loosening.

[0046] As shown in Figure 2 The top of the connecting platform 14 of the embodiment is provided with a connecting nut 143, and the bolt 144 is arranged in the connecting nut 143. The bolt 144 is threadedly connected with the nut, and the fixing seat 1 is fixed or limited by the cooperation of the nut and the bolt 144.

[0047] Preferably, the hole diameter of the screw hole of the nut is smaller than the hole diameter of the first connecting hole 141, so as to avoid the interference of the bolt 144 with the wear-resistant sleeve 2 when the bolt 144 extends into the first connecting hole 141.

[0048] As shown in Figure 2 The upper and lower ends of the connecting groove 15 of the embodiment are both provided with a cutting part 151, and the included angle b between the cutting part 151 and the end face of the fixing seat 1 is 110°-130°.

[0049] The cutting part 151 is arranged to make the connecting groove 15 more easily achieve close cooperation with the cooperating piece, such as the connecting component, during assembly. This design reduces the frictional resistance during assembly, improves the assembly efficiency, and also helps to ensure that the connection between the connecting groove 15 and the cooperating piece is more firm and stable.

[0050] The included angle b between the cutting part 151 and the end face of the fixing seat 1 is set to 110°-130°, and the selection of this angle helps to optimize the structural strength of the connecting groove 15. When subjected to external force, the cutting part 151 can disperse and bear part of the stress, thereby reducing the stress concentration phenomenon of the connecting groove 15 and its surrounding area. This design improves the overall structural strength of the fixing seat 1 and the wear-resistant sleeve 2, prolonging the service life of the equipment.

[0051] Specifically, the included angle b can be 110°, 120°, or 130°, and the embodiment takes 120° as an example.

[0052] As shown in Figure 2 The connecting part of the first fixing groove 11 and the second fixing groove 12 and the connecting part of the second fixing groove 12 and the end face of the fixing seat 1 of the embodiment are both provided with a guide chute 121.

[0053] The setting of the guide chute 121 makes the wear-resistant sleeve 2 more easily slide into the first fixing groove 11 and the second fixing groove 12 during installation, thereby greatly simplifying the installation steps. This design reduces the time and labor cost required for installation, and improves work efficiency.

[0054] As shown in Figure 1 and Figure 2 The embodiment also includes a fixing frame 3 for connecting with the grinding equipment,

[0055] The fixing frame 3 is provided with a connecting piece 31 corresponding to the connecting groove 15, and the inner side of the connecting piece 31 is provided with a connecting block 32 which is in sliding connection with the connecting groove 15.

[0056] The setting of the fixing frame 3 makes the connection between the wear-resistant sleeve 2 and the grinding equipment more stable. Through the corresponding matching of the connecting piece 31 and the connecting groove 15, and the sliding connection of the connecting block 32 and the connecting groove 15, it is realized that the wear-resistant sleeve 2 can slide along the fixing frame 3.

[0057] Specifically, the fixing frame 3 is provided with a fixing hole, and by screwing a screw into the fixing hole and connecting it with the grinding equipment, the fixing frame 3 can be fixed.

[0058] As shown in Figure 2 The top of the connecting block 32 of the embodiment is provided with a guide sliding inclined surface 321. The setting of the guide sliding inclined surface 321 makes the connecting block 32 more smooth during sliding into the connecting groove 15, reducing the resistance and friction during installation.

[0059] As shown in Figure 2 The fixing frame 3 of the embodiment is provided with a stop portion 33 for limiting the shaft rod of the high polymer material conveying wheel.

[0060] The setting of the stop portion 33 can effectively limit the movement of the shaft rod of the high polymer material conveying wheel within a certain range, preventing it from being dislodged due to vibration or external force. The stability and safety of the conveying wheel during operation are ensured.

[0061] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range will be changed, and the content of the specification should not be understood as a limitation of the present application.
