It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] On the one hand, see Figures 1 to 5 The transmission structure proposed in this embodiment includes a driving bearing member 1, a driven bearing assembly 2 and a plurality of connecting blocks 3. The driving bearing member 1 is connected to the driven bearing assembly 2 through the connecting block 3. The driven bearing assembly 2 includes a plurality of first bearing members 21 and a plurality of second bearing members 22. Both sides of the first bearing member 21 are connected to the driving bearing member 1 or the second bearing member 22 through the connecting block 3. The first bearing member 21 and the second bearing member 22 are connected through the connecting block 3. The axis of the driving bearing member 1 coincides with the axis of the plurality of second bearing members 22. The axes of any two adjacent first bearing members 21 are parallel and do not coincide. The first bearing member 21 is fixedly connected to the screen plate, and the driving bearing member 1 and the second bearing member 22 are fixedly connected to the screen frame.

[0035] When the transmission structure starts to work, the driving bearing member 1 starts to rotate, driving the connecting block 3 to rotate relative to the axial direction of the driving bearing member 1, thereby driving the first bearing member 21 and the screen plate fixedly connected to the first bearing member 21 to move up and down, front and back; since the driving bearing member 1 or the second bearing member 22 is transmission-connected on both sides of the first bearing member 21, and the axes of the driving bearing member 1 and the second bearing member 22 coincide, the first bearing members 21 can all rotate relative to the axis of the driving bearing member 1, thereby ensuring the stability and regularity of the rotation of the first bearing member 21; and since the axes of the two adjacent first bearing members 21 are parallel but not coincident, during the rotation of the first bearing member 21, there is a height difference between the adjacent screen plates, which can facilitate the separation of the materials on the screen plates; the transmission structure is equivalent to splitting the entire rotating shaft into several first bearing members 21 and second bearing members 22, and using the connecting block 3 to form an amplitude to ensure the vibration of the screen plate. When the transmission structure is damaged, only the corresponding damaged parts need to be replaced, and the entire transmission structure does not need to be disassembled and replaced, thereby improving the maintenance efficiency of the transmission structure and reducing the maintenance cost of the transmission structure.

[0036] It should be noted that see Figure 4 and Figure 5 The connecting block 3 is provided with a first through hole and a second through hole, the first connecting shaft 211 of the first bearing member 21 is plugged into the first through hole, and the driving connecting shaft 11 of the driving bearing member 1 or the second connecting shaft 222 of the second bearing member 22 is plugged into the second through hole. The arrangement of the first through hole and the second through hole on the connecting block 3 makes the axis of the driving bearing member 1 and the axis of the second bearing member 22 coincide, while the axis of the driving bearing member 1 is parallel to but not coincident with the axis of the first bearing member 21, so that the several connecting blocks 3 drive the first connecting shaft 211 to rotate relative to the axis direction of the driving bearing member 1, thereby driving the screen plate to vibrate.

[0037] Preferably, the shape of the first through hole is different from the shape of the second through hole. In this way, the through holes corresponding to the driving connecting shaft 11, the first connecting shaft 211 and the second connecting shaft 222 can be quickly distinguished, the efficiency and accuracy of the installation of the connecting block 3 are improved, and the amplitude of the first bearing member 21 can be changed by adjusting the installation angle to adapt to various working conditions.

[0038] Specifically, see Figure 4 and Figure 5 In this embodiment, the first through hole is octagonal and the second through hole is hexagonal. Such a configuration can not only distinguish the first through hole and the second through hole, but also improve the opening efficiency of the first through hole and the second through hole on the connecting block 3. Of course, the shapes of the first through hole and the second through hole can also be adjusted according to actual conditions, which will not be elaborated here.

[0039] Preferably, the connection block 3 includes a plurality of connection blocks, and any two adjacent connection blocks are fixedly connected by bolts. The plurality of connection blocks are sleeved on the drive connection shaft 11, the first connection shaft 211 or the second connection shaft 222 in a direction perpendicular to the axis of the drive bearing member 1, and the plurality of connection blocks are fixedly connected by bolts, which can not only realize the installation of the connection block 3 in a small space, but also ensure the connection stability between the connection block 3 and the drive connection shaft 11, the first connection shaft 211 or the second connection shaft 222.

[0040] The transmission structure further includes a driving member, which is in transmission connection with the driving bearing member 1 and can drive the driving bearing member 1 to rotate. Such a configuration can drive the driving bearing member 1 to rotate, and then drive the driven bearing assembly 2 to rotate, so as to realize the screening of the material by the screen plate.

[0041] Optionally, the driving member is a motor.

[0042] Specifically, the two connecting blocks 3 on both sides of the first bearing member 21 have the same posture.

[0043] Optionally, the angle between the connecting blocks 3 connected to any two adjacent first bearing members 21 is 120°. This arrangement can ensure that the first bearing seat 212 vibrates regularly.

[0044] As an alternative, the angle between the connecting blocks 3 connected to any two adjacent first bearing members 21 is 180°.

[0045] Among them, see Figure 1The driving bearing member 1 includes a driving bearing, a driving connecting shaft 11 and a driving bearing seat 12. The driving connecting shaft 11 is passed through the inner ring of the driving bearing and is fixedly connected to the connecting block 3. The driving bearing seat 12 connects the driving bearing and the screen frame. Such an arrangement can not only ensure the stability of the position of the driving bearing member 1, but also enable the connecting block 3 connected to the driving bearing member 1 to rotate relative to the axis of the driving bearing member 1, thereby driving the movement of the first bearing seat 212 and the screen plate.

[0046] Further, see Figure 4 The first bearing member 21 includes a first bearing, a first connecting shaft 211 and a first bearing seat 212. The first connecting shaft 211 is inserted into the inner ring of the first bearing and fixedly connected to the connecting block 3. The first bearing seat 212 connects the first bearing and the screen plate. Such an arrangement can not only ensure the fixed connection between the first bearing member 21 and the screen plate, but also realize the connection between the first bearing member 21 and the connecting block 3, and then vibrate under the action of the driving bearing member 1.

[0047] Further, see Figure 3 The second bearing member 22 includes a second bearing 221, a second connecting shaft 222, and a second bearing seat 223. The second connecting shaft 222 is passed through the inner ring of the second bearing 221 and is fixedly connected to the connecting block 3. The second bearing seat 223 connects the second bearing 221 and the screen frame. Such an arrangement can not only ensure the stability of the position of the second bearing member 22 relative to the screen frame, but also realize the transmission connection with the first bearing member 21.

[0048] Optionally, the connection block 3 is made of alloy steel material. Preferably, the connection block 3 is made of 45# steel.

[0049] On the other hand, the present embodiment also proposes a bouncing screen, which includes a plurality of screen plates, a screen frame, and a transmission structure of any of the above schemes, wherein a plurality of first bearing members 21 are connected to the plurality of screen plates in a one-to-one correspondence, and the driving bearing member 1 and the second bearing member 22 are both fixedly connected to the screen frame. The screen plates can be driven to vibrate on the basis of the transmission structure, and even if the parts of the transmission structure are damaged, only the damaged parts need to be replaced, the maintenance cost is low and the maintenance efficiency is high, thereby improving the screening efficiency of the bouncing screen.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
