Description

Technical Field

[0001] This invention relates to a circulating transmission conveying device, belonging to the technical field of material conveying devices. Background Technology

[0002] In the field of material handling, chains are often used to transport materials, especially when the chain is placed vertically and a pallet is fixed on the chain to support the material. Through the cyclical movement of the chain, the pallet can be moved up and down, thereby realizing the upward or downward movement of the material on the pallet and realizing the conveying of the material in the vertical direction.

[0003] For example, the vertical conveyor for a steel drum automated warehouse disclosed in Chinese utility model patent CN204264800U includes two sets of steel drum lifting devices. Between the two sets of lifting devices is a steel drum lifting and conveying channel. Below the steel drum lifting and conveying channel is a bottom conveyor roller conveyor. Multiple storage conveyor roller conveyors are spaced vertically along the sides of the two sets of lifting devices. Both the storage conveyor roller conveyors and the bottom conveyor roller conveyor convey materials horizontally, and their conveying directions are perpendicular. In use, the steel drums are transported from the bottom conveyor roller conveyor to the space between the two sets of lifting devices. Each set of lifting devices has a support plate fixed to its chain. The support plates on both sides support the bottom of the steel drum and lift it upwards. When the drum reaches the corresponding height of the storage conveyor roller conveyor, a drum pushing device pushes the drum from the support plate onto the storage conveyor roller conveyor, thus realizing the transfer of the steel drum from the bottom conveyor roller conveyor to the steel drum lifting device and then to the storage conveyor roller conveyor.

[0004] However, during the process of pushing the steel drum to the storage conveyor rollers, the steel drum lifting device must stop operating. Otherwise, the steel drum will cross the corresponding storage conveyor rollers, resulting in transfer failure. This is especially true when the pallet is about to reach the top; the steel drum lifting device must be stationary when transferring the steel drum to the uppermost storage conveyor roller. Otherwise, the pallet will cross the top and cycle to the other side, causing the steel drum to fall. Furthermore, for situations where materials are simply lifted to the top by a chain conveyor and then transferred by other conveyors, the chain conveyor also needs to stop operating before the pallet reaches the top. Otherwise, once the pallet leaves the material, the material will fall. In this case, the chain conveyor is not operating continuously, requiring frequent start-stop control and precise control of the stopping position, making the control complex and difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a circulating transmission conveying device to solve the problems of complex and difficult control caused by the need for frequent start-stop control and precise control of the stopping position in the process of lifting materials in existing chain conveying devices.

[0006] To achieve the above objectives, the circulating transmission conveying device of the present invention adopts the following technical solution: A circulating transmission conveying device includes a vertically arranged chain mechanism, which includes a chain and a support member fixed on the chain to support materials. The circulating transmission conveying device also includes a fixed seat fixed relative to the chain mechanism, on which a receiving seat is rotatably mounted. The receiving seat has a support part for supporting materials and a force-receiving part that rotates open when pushed by upward-moving materials. The circulating transmission conveying device also includes an elastic element for deforming under force during the rotation of the receiving seat, so that after the materials pass over the receiving seat, the receiving seat rotates back to its original position, thereby moving the support part below the materials. The receiving seat rotates back to its original position before the support member disengages from the materials, so that after the support member moves to the upper end and disengages from the materials, the receiving seat supports the materials.

[0007] The beneficial effects of the above technical solution are as follows: This invention proposes an improved circulating transmission conveying device. The improvement lies in that the circulating transmission conveying device further includes a fixed base fixedly arranged relative to the chain mechanism. A receiving seat is rotatably mounted on the fixed base. The receiving seat has a support part for supporting materials and a force-receiving part that rotates open under the pushing action of the upwardly moving materials. In this way, the receiving seat can support the materials through the support part, and at the same time, the force-receiving part can rotate open under the pushing action of the upwardly moving materials. Furthermore, the circulating transmission conveying device also includes an elastic element for deformation under force during the rotation of the receiving seat. After the material passes the receiving seat upwards, the reaction force of the elastic element causes the receiving seat to rotate back to its original position, thereby moving the support part below the material. The receiving seat rotates back to its original position before the support part disengages from the material. In this way, when the support part moves to the upper end and disengages from the material, the receiving seat can support the material, preventing it from falling and facilitating its transfer to other conveying devices. The support part does not need to remain stationary to wait for the material to be transferred to other conveying devices, meaning the chain can operate continuously without the need to stop the chain mechanism. Compared with existing technologies, this greatly simplifies the control operation and reduces the control difficulty.

[0008] Furthermore, the circulating transmission conveyor also includes a control mechanism for controlling the receiving seat to open during downward material transport to prevent the support from blocking the material from moving downward. After the receiving seat opens, the support member supports the material and drives it downward.

[0009] Furthermore, the control mechanism includes a guide seat and a control rod that guides the guide seat up and down. A rotating arm that rotates synchronously with the receiving seat is installed on the fixed seat. The rotating arm is hinged to the control rod. The elastic element cooperates with the control rod. The control mechanism also includes a swing arm that swings along a fixed axis and is hinged to the control rod, and a pusher that intermittently pushes the swing arm to rotate so that the swing arm drives the control rod to move up or down. When the control rod moves up or down, it drives the receiving seat to rotate open through the rotating arm.

[0010] Furthermore, the control lever includes an upper control lever and a lower control lever that are sleeved together and connected by a pin. The upper control lever and the lower control lever are respectively provided with pin holes for the pin to pass through, and one of the pin holes is an elongated hole extending vertically, while the other pin hole is a round hole adapted to the pin. One of the upper control lever and the lower control lever is hinged to the swing arm, and the other is hinged to the rotating arm.

[0011] Furthermore, the chain mechanism includes an upper sprocket and a lower sprocket for mounting the chain, and the control mechanism also includes a drive wheel and a synchronous wheel that is coaxial with and rotates synchronously with the upper sprocket or the lower sprocket. The drive wheel and the synchronous wheel are in a transmission engagement, and the pushing member is disposed on the drive wheel.

[0012] Furthermore, the guide seat includes an upper guide seat and a lower guide seat arranged vertically, the elastic element is a lower return spring sleeved on the lower end of the control rod, and a lower stop is also provided at the lower end of the control rod, with the lower return spring mounted between the lower stop and the lower guide seat.

[0013] Furthermore, the guide seat includes an upper guide seat and a lower guide seat arranged vertically. An upper return spring is sleeved on the upper end of the control rod, and an upper stop is also provided on the upper end of the control rod. The upper return spring is mounted between the upper stop and the upper guide seat.

[0014] Furthermore, only one chain mechanism is provided, and the circulating transmission conveying device also includes a guide channel for material to pass through and guide the material's up and down movement. The guide channel wall is provided with a vertically extending groove for the support member to extend into the guide channel.

[0015] Furthermore, the chain mechanism has two chains, and the support component is fixedly installed between the two chains.

[0016] Furthermore, the circulating transmission conveying device includes a guide seat and a control rod that guides the guide seat up and down. A rotating arm that rotates synchronously with the receiving seat is installed on the fixed seat. The rotating arm is hinged to the control rod, and the elastic element cooperates with the control rod. Attached Figure Description

[0019] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0020] To address the technical problems existing in the prior art, the basic technical concept of this invention is to set up a rotatable receiving seat. The receiving seat has a supporting part and a force-bearing part. The force-bearing part can rotate open under the pushing action of the upward-moving material. After the material passes over the receiving seat, the receiving seat rotates back to its original position under the reaction force of the elastic element, thereby moving the supporting part below the material. Moreover, the receiving seat rotates back to its original position before the supporting part separates from the material. In this way, after the supporting part moves to the upper end and separates from the material, the receiving seat can support the material, preventing the material from falling. The chain can operate continuously without the need to control the chain mechanism to stop. Compared with the prior art, this greatly simplifies the control operation and reduces the control difficulty.

[0021] An embodiment of the circulating transmission conveying device in this invention: like Figure 1As shown, the circulating transmission conveyor includes a vertically arranged chain mechanism, combined with... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the chain mechanism includes an upper sprocket 15 and a lower sprocket 17 arranged vertically, and a chain 16 mounted on the upper sprocket 15 and the lower sprocket 17. Two sets of the upper sprocket 15, lower sprocket 17, and chain 16 are arranged side-by-side, forming a double-row ring structure. A support member for supporting the material 20 is fixedly disposed between the two chains 16. In this embodiment, the material 20 is cylindrical, and the support member is a support rod 18. Multiple support rods 18 are evenly spaced on the chain 16. The upper sprocket 15 is the main power input actuator, and the chain 16 operates continuously. When the chain 16 rotates counterclockwise, the support rod 18 supports the material 20 upwards; conversely, when the chain 16 rotates clockwise, the support rod 18 supports the material 20 downwards.

[0022] like Figure 1 As shown, only one chain mechanism is provided in this embodiment. The circulating transmission conveying device also includes a guide channel 22 for the material 20 to pass through and guide the up and down movement of the material 20. In order for the support rod 18 to support the material 20, a vertically extending groove is provided on the channel wall of the guide channel 22 for the support rod 18 to extend into the guide channel 22. Figure 2 As shown, when material 20 is conveyed upwards, the material is fed by a transverse conveying mechanism 19 (the conveying direction of the transverse conveying mechanism 19 is perpendicular to the vertical direction), as follows. Figure 3 As shown, when the support rod 18 rotates to the bottom of the material 20 (at this time, the upper end of the material 20 is aligned with the guide channel 22), it supports the material 20 and moves it upwards, as shown. Figure 4 As shown. Conversely, when the material 20 is conveyed downwards, the support rod 18 supports the material 20 as it descends, eventually placing the material 20 onto the transverse conveying mechanism 19, which then continues to convey the material 20 laterally.

[0023] In this invention, such as Figure 1 As shown, the circulating transmission conveying device also includes a fixed base 13 fixedly disposed relative to the chain mechanism. A receiving seat 5 is rotatably mounted on the fixed base 13. The receiving seat 5 has a support part for supporting the material 20 and a force-receiving part that rotates open when pushed by the upwardly moving material 20. The support part is the end of the receiving seat 5, and the force-receiving part is the side of the receiving seat 5. In this embodiment, the circulating transmission conveying device also includes a control mechanism for controlling the receiving seat 5 to rotate open when the material 20 is transported downward to prevent the support part from blocking the material 20 from descending. After the receiving seat 5 rotates open, the supporting rod 18 supports the material 20 and drives it downward.

[0024] Specifically, the control mechanism includes a guide seat and a control rod that guides the guide seat vertically. The control rod is located on the side of the receiving seat 5 that is biased towards the chain mechanism. The guide seat includes an upper guide seat 9, a middle guide seat 25, and a lower guide seat 26 arranged vertically at intervals. The control rod includes an upper control rod 4 and a lower control rod 7 connected by a first pin 11. A rotating arm 6 that rotates synchronously with the receiving seat 5 is mounted on the fixed seat 13. The rotating arm 6 is hinged to the lower control rod 7 by a second pin 12, and the pin hole on the rotating arm 6 through which the second pin 12 passes is an elongated hole. When the force-bearing part of the receiving seat 5 is pushed open by the upwardly moving material 20, such as Figure 1 As shown, the receiving seat 5 and the rotating arm 6 rotate synchronously clockwise, and the rotating arm 6 drives the lower control rod 7 to move upward. The circulating transmission conveying device also includes an elastic element for deformation under force during the rotation of the receiving seat 5. In this embodiment, the elastic element is a lower return spring 8 that cooperates with the lower control rod 7. The lower return spring 8 is sleeved on the lower end of the lower control rod 7, and a lower stop is also provided at the lower end of the lower control rod 7. The lower return spring 8 is mounted between the lower stop and the lower guide seat 26.

[0025] Specifically, in this embodiment, the lower end of the lower control lever 7 is a threaded section, such as... Figure 1 As shown, the lower stop is a lower nut 21 installed at the lower end of the lower control rod 7, and a lower return spring 8 is mounted between the lower nut 21 and the lower guide seat 26. When the rotating arm 6 drives the lower control rod 7 upward, the lower return spring 8 is compressed and deformed. Therefore, when the material 20 passes the receiving seat 5 upward, under the reaction force of the lower return spring 8, the receiving seat 5 rotates back to its original position, and the support part of the receiving seat 5 moves below the material 20. The receiving seat 5 rotates back to its original position before the support rod 18 disengages from the material 20, so that after the support rod 18 moves to the upper end and disengages from the material 20, the receiving seat 5 supports the material 20, making it convenient for the material 20 to be transferred away by other conveying devices. Therefore, the chain 16 can operate continuously, and the support rod 18 does not need to be stationary to wait for the material 20 to be transferred away by other conveying devices. That is, there is no need to control the chain mechanism to stop, which greatly simplifies the control operation and reduces the control difficulty compared with the prior art.

[0026] Of course, in this invention, the extreme position of the receiving seat 5 to return to its original position is guaranteed by a corresponding limiting structure. For example, a stop pin or stop block can be set at a suitable position on the fixed seat 13 to prevent the receiving seat 5 or the rotating shaft on which the receiving seat 5 is located from rotating counterclockwise to the limit, thereby ensuring that the support part of the receiving seat 5 can support the material 20 smoothly and stably.

[0027] like Figure 1As shown, the control mechanism also includes a swing arm 3 that swings along a fixed axis and is hinged to the upper control lever 4, and a pusher that intermittently pushes the swing arm 3 to rotate so that the swing arm 3 drives the upper control lever 4 to move up or down. The swing arm 3 and the upper control lever 4 are hinged by a third pin 10, and the pin hole on the swing arm 3 through which the third pin 10 passes is an elongated hole. When the upper control lever 4 moves up, it drives the lower control lever 7 to move up, which in turn drives the receiving seat 5 to rotate open through the rotating arm 6. Furthermore, the control mechanism also includes a drive wheel and a synchronous wheel that is coaxial with and rotates synchronously with the upper sprocket 15. The synchronous wheel is a pinion 14, and both the pinion 14 and the upper sprocket 15 are mounted on the drive shaft. The drive wheel is a large gear 1, and the pinion 14 directly meshes with the large gear 1 for transmission. When the upper sprocket 15 drives the chain mechanism, the pinion 14 rotates synchronously, which in turn drives the large gear 1 to rotate synchronously. The aforementioned pusher is a pusher block 2 mounted on the large gear 1. When the material 20 is transported downwards, the upper sprocket 15 rotates clockwise, the large gear 1 rotates counterclockwise, and the pusher block 2 pushes the swing arm 3 to swing upwards, thereby driving the upper control rod 4 and the lower control rod 7 to move upwards. The receiving seat 5 rotates open, and the downward reset of the receiving seat 5, the upper control rod 4, and the lower control rod 7 is achieved by the lower reset spring 8.

[0028] When material 20 is transported upwards, the upper sprocket 15 rotates counterclockwise, the large gear 1 rotates clockwise, and the push block 2 pushes the swing arm 3 downwards, thereby causing the upper control lever 4 to move downwards without affecting the upward movement of material 20. To facilitate the upward reset of the swing arm 3, such as... Figure 1 As shown, an upper return spring 23 is sleeved on the upper end of the upper control rod 4, and an upper stop is also provided on the upper end of the upper control rod 4. The upper return spring 23 is mounted between the upper stop and the upper guide seat 9. Specifically, in this embodiment, the upper end of the upper control rod 4 is a threaded section, the upper stop is an upper nut 24 installed on the upper end of the upper control rod 4, and the upper return spring 23 is mounted between the upper nut 24 and the upper guide seat 9.

[0029] Because the chain 16 operates continuously without stopping, the large gear 1 drives the push block 2 to operate continuously without stopping. When transporting material 20 upward, after material 20 passes the receiving seat 5 and separates from the support rod 18, the receiving seat 5 supports the material. If material 20 has not yet been transferred away by other conveying devices, but the push block 2 rotates clockwise to the position of the swing arm 3, it will push the swing arm 3 to swing downward. Or, when the receiving seat 5 is in the rotation return position, if the push block 2 rotates clockwise, it will always be in contact with the swing arm 3 and push the swing arm 3 to swing downward. This will cause the upper control rod 4 to move downward. At this time, if the upper control rod 4 drives the lower control rod 7 to move downward, then the receiving seat 5 will no longer be able to continue to rotate counterclockwise, and the mechanism will be stuck. To avoid this phenomenon, in this embodiment, the upper control lever 4 and the lower control lever 7 are sleeved together. Specifically, the lower control lever 7 is inserted into the upper control lever 4, and the pin hole on the upper control lever 4 through which the first pin 11 passes is a round hole adapted to the first pin 11. The pin hole on the lower control lever 7 through which the first pin 11 passes is an elongated hole extending vertically. In this way, when the upper control lever 4 moves downward, the first pin 11 moves downward within the pin hole of the lower control lever 7, while the lower control lever 7 remains stationary. This avoids the upper control lever 4 driving the lower control lever 7 downward. Of course, there are other situations as well: when the upper control lever 4 moves upward, it can drive the lower control lever 7 to move upward synchronously; when the lower control lever 7 moves downward, it can drive the upper control lever 4 to move downward synchronously; when the lower control lever 7 moves upward, the upper control lever 4 remains stationary within a certain stroke.

[0030] It should be noted that the chain mechanism is located on one side of the material 20, the support rod 18 supports the middle position of the bottom of the material 20, the force-bearing part of the receiving seat 5 is matched with the middle position of the top of the material 20, while the upper control rod 4, the swing arm 3, the large gear 1, the lower control rod 7 and the rotating arm 6 are offset on one side of the material 20. This can be achieved by extending the corresponding rotating shaft to avoid interfering with the upward or downward movement of the material 20.

[0031] The specific working process of the circulating transmission conveying device in this invention is as follows: like Figure 6 As shown, when the material 20 is transported upwards, the upper sprocket 15 rotates counterclockwise due to the power input from the drive shaft, driving the chain 16 to rotate counterclockwise. When the support rod 18 on the side of the receiving seat 5, where the chain 16 is located, drives the material 20 upwards, the receiving seat 5 rotates clockwise under the squeezing action of the material 20, thereby driving the rotating arm 6 to rotate clockwise. The rotating arm 6 drives the lower control rod 7 upwards and compresses the lower return spring 8. During this process, the upper control rod 4 does not affect the upward movement of the material 20. Figure 7As shown, after material 20 passes the receiving seat 5, the squeezing effect of material 20 on the receiving seat 5 is released. The lower control rod 7 resets downward under the action of the lower return spring 8, driving the receiving seat 5 and the rotating arm 6 to rotate counterclockwise and reset. At this time, the support part of the receiving seat 5 rotates to below the material 20, ready to receive the material 20. After that, the chain mechanism continues to run, and the support rod 18 continues to drive the material 20 upward. When the support rod 18 moves to the upper end and disengages from the material 20 under the guidance of the upper sprocket 15, the material 20 will slide slightly under its own weight and be caught by the receiving seat 5. Figure 8 As shown.

[0032] Subsequently, the chain mechanism continues to operate. When the push block 2 rotates clockwise with the large gear 1 to the position of the swing arm 3, the push swing arm 3 swings downward counterclockwise. The swing arm 3 drives the upper control rod 4 to move downward. The first pin 11 on the upper control rod 4 moves downward in the pin hole of the lower control rod 7, while the lower control rod 7 remains stationary. During this process, the upper return spring 23 is compressed and deformed. After the push block 2 passes the swing arm 3, the upper control rod 4 returns to its original position under the action of the upper return spring 23, thereby driving the swing arm 3 to swing upward clockwise to return to its original position. Figure 8 As shown, the support rod 18 moves to its uppermost position at this time.

[0033] Then, the transverse conveyor 19 begins to transport the next material 20 laterally, such as... Figure 2 As shown, this fills the material gap, while the material 20 that was just conveyed is transferred away by other conveying devices, realizing the automatic handover of the upper fixed-point receiving of material 20, the overtravel of the chain mechanism support rod 18, and the lower horizontal conveying mechanism 19 and vertical transfer. The vertical spacing between two adjacent support rods 18 on the chain 16 is 82 links. Each time a support rod 18 moves upward, the large gear 1 rotates one revolution, and this cycle repeats, allowing the material 20 transferred from the horizontal conveying mechanism 19 to be repeatedly transported to the receiving seat 5.

[0034] When material 20 is transported downwards, material 20 is first received by receiving seat 5, and then... Figure 9 As shown, the upper sprocket 15 rotates clockwise due to the power input from the drive shaft, driving the chain 16 to rotate clockwise, and through the small gear 14, driving the large gear 1 to rotate counterclockwise. The push block 2 on the large gear 1 pushes the swing arm 3 to swing clockwise upward, thereby driving the upper control rod 4 to move upward. The upper control rod 4 drives the lower control rod 7 to move upward synchronously. During this process, the lower return spring 8 is compressed and deformed, simultaneously driving the receiving seat 5 and the rotating arm 6 to rotate clockwise. The receiving seat 5 rotates open, releasing the obstruction of the material 20. The material 20 falls onto the support rod 18 under its own weight, and follows the support rod 18 downward until it falls onto the transverse conveying mechanism 19. In the above process, when the receiving seat 5 rotates open, under the continuous action of the push block 2 and the swing arm 3, the receiving seat 5 remains in the rotated position for a certain period of time. Figure 10As shown, when the material 20 descends to the upper part and disengages from the receiving seat 5, the lower control rod 7 descends and resets under the action of the lower reset spring 8, thereby driving the receiving seat 5 and the rotating arm 6 to rotate counterclockwise and reset. At the same time, the lower control rod 7 drives the upper control rod 4 to descend and reset, and then the upper control rod 4 drives the swing arm 3 to swing counterclockwise downward and reset.

[0035] This process enables the automatic release of material 20 at a fixed point on the receiving seat 5. When the support rod 18 moves to the lower end and the material 20 descends to the horizontal conveying mechanism 19, the vertical and horizontal transfers are switched. The horizontal conveying mechanism 19 then transfers the material 20 away. Each time the support rod 18 moves downward, the large gear 1 rotates once, and this cycle repeats, allowing the material 20 descending from the receiving seat 5 to be transferred away by the horizontal conveying mechanism 19 repeatedly.

[0036] In other embodiments of the circulating transmission conveying device: the supporting member can also be a supporting plate or a supporting block, and the pushing member can also be a pushing rod or a pushing plate.

[0037] In other embodiments of the circulating transmission conveyor: the chain mechanism may also have only one chain, in which case the support is directly fixed to the chain link.

[0038] In other embodiments of the circulating transmission conveying device: two sets of chain mechanisms can also be set up, with the two sets of chain mechanisms symmetrically arranged on both sides of the material. In this case, the material is supported by the support members on both sides at the same time. Since the support stability is guaranteed, the guide channel can be omitted.

[0039] In other embodiments of the cyclic transmission conveyor, the middle guide seat can be omitted, and the control rod can be guided only by the upper and lower guide seats.

[0040] In other embodiments of the circulating transmission conveying device: the upper stop at the upper end of the upper control rod can also be a stop pin installed on the upper control rod, or an annular boss integrally formed on the upper end of the upper control rod; in other embodiments, when the upper control rod moves downward and the swing arm swings downward counterclockwise, the upper return spring can be omitted from the upper end of the upper control rod, and a tension spring can be connected between the upper end of the upper control rod and the fixed object. In this case, when the upper control rod moves downward, the tension spring is stretched and deformed, or a torsion spring can be installed on the rotating shaft where the swing arm is located. When the swing arm swings downward counterclockwise, the torsion spring is deformed by force, which can also provide power for the reset of the upper control rod and the swing arm.

[0041] In other embodiments of the circulating transmission conveying device: the lower stop at the lower end of the control rod can also be a stop pin installed on the lower control rod, or an annular boss integrally formed on the lower end of the lower control rod; in other embodiments, the elastic element may not be a lower return spring sleeved on the lower end of the lower control rod, but a tension spring connected between the lower end of the lower control rod and the fixed object, or a torsion spring installed on the rotating shaft where the rotating arm is located, which can also provide power for the reset of the lower control rod, the rotating arm and the receiving seat.

[0042] In other embodiments of the circulating transmission conveyor: when both the drive wheel and the synchronizing wheel are gears, one or more transmission gears may be provided between them; or in other embodiments, both the drive wheel and the synchronizing wheel may be sprockets, and they may be driven by a chain.

[0043] In other embodiments of the circulating transmission conveyor device: depending on the specific arrangement of the drive wheel, the synchronizing wheel can also be coaxial with the lower sprocket and rotate synchronously. Of course, in other embodiments, the synchronizing wheel may not be provided, and only the drive wheel may be provided, with its rotation controlled by an independent power source. In other embodiments, neither the drive wheel nor the synchronizing wheel may be provided. In this case, a direct-acting power device, such as a hydraulic cylinder, pneumatic cylinder, or electric push rod, can be provided. When the swing arm needs to rotate, the output end of the direct-acting power device extends directly to push the swing arm to rotate, and can retract to reset the swing arm. In this case, the output end of the direct-acting power device constitutes a pushing component.

[0044] In other embodiments of the circulating transmission conveying device: when the upper control rod and the lower control rod are sleeved and connected by a pin, the lower end of the upper control rod can be inserted into the lower control rod. The pin hole on the upper control rod through which the pin passes is an elongated hole extending vertically, and the pin hole on the lower control rod through which the pin passes is a round hole adapted to the pin. This also enables the lower control rod to move upward synchronously when the upper control rod moves upward, and the lower control rod to remain stationary when the upper control rod moves downward. Similarly, when the lower control rod moves upward, the upper control rod remains stationary, and when the lower control rod moves downward, the upper control rod to move downward synchronously.

[0045] In other embodiments of the cyclic transmission conveying device: depending on the specific setting position of the swing arm and the desired motion effect, the upper control rod can also be hinged to the rotating arm, while the lower control rod is hinged to the swing arm. In other embodiments, when the jacking member is not set on a continuously rotating drive wheel, for example, on an independently controlled drive wheel, or when the swing arm rotation is controlled by the output end of the direct-drive power device as mentioned above, since the swing arm's movement is independently controlled, it is not necessary for either the upper or lower control rod to have a long hole. In this case, the upper and lower control rods can be a single control rod.

[0046] In other embodiments of the circulating transmission conveyor: depending on the specific setting position of the control lever, for example when the control lever is located on the side of the receiving seat away from the chain mechanism, according to the symmetry effect, the control lever needs to move downward to make the rotating arm drive the receiving seat to rotate open.

[0047] In other embodiments of the circulating transmission conveyor: the control mechanism may not include the swing arm and the pushing component. In this case, a direct-acting power device can be directly installed beside the control rod, the rotating arm, or the receiving seat. The output end of the direct-acting power device directly pushes the control rod, the rotating arm, or the receiving seat to move, causing the receiving seat to rotate open, thereby preventing the support from blocking the material from flowing downward. Of course, in other embodiments, if the rotating arm is directly pushed, the control rod can be omitted; and if the receiving seat is directly pushed, the rotating arm can also be omitted.

[0048] In other embodiments of the circulating transmission conveyor: the circulating transmission conveyor can be used only for conveying materials upward, in which case there is no need to set up a control mechanism to control the opening of the receiving seat when conveying materials downward.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
