Description

Technical Field

[0001] This invention relates to the technical field of sludge conveying, and more specifically, to a conveyor equipped with a tensioning mechanism. Background Technology

[0002] Sludge conveyors are devices used to transport sludge. Typically, sludge conveyors use conveyor plates between two sets of closed-loop conveyor chains to transport sludge by following the rotating rods of the conveyor chains.

[0003] During the sludge conveyor's transport of sludge, it is necessary to ensure the tension of the conveyor chain. This requires adjusting the position of the sprocket using cylinders or hydraulic cylinders. However, in actual use, the cylinders or hydraulic cylinders often malfunction, resulting in insufficient air and oil pressure. This can prevent the sprockets from receiving enough force, causing the conveyor chain to lose its tension. Summary of the Invention

[0034] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0035] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0036] Example: A conveyor equipped with a tensioning mechanism, see attached document. Figure 1 - Appendix Figure 6 The system includes a transmission chain 3, sprockets 5, chain plates 4, and a tensioning mechanism 2. Two transmission chains 3 are provided, arranged side-by-side. Both ends of each transmission chain 3 are equipped with sprockets 5, and the two sprockets 5 at the same end of each transmission chain 3 are connected together by a synchronous shaft 51. Several chain plates 4 for transporting sludge are connected to the two transmission chains 3 between them. Two tensioning mechanisms 2 are provided to tension the transmission chains 3, located at opposite ends of the same synchronous shaft 51. The tensioning mechanism... Component 2 includes a slider 21, meshing teeth 22, a power component 24, and a pawl 23. The end of the synchronous shaft 51 is rotatably connected to the slider 21, which can slide along the transmission direction of the transmission chain 3. Several meshing teeth 22 arranged along the sliding direction of the slider 21 are fixedly connected to the top of the slider 21. The power component 24 is used to push the slider 21 to slide. The pawl 23 is located on the top of the slider 21, and can mesh with the meshing teeth 22, allowing the slider 21 to slide only in a direction away from the other synchronous shaft 51. The power component 24 is configured as a cylinder or a hydraulic cylinder.

[0037] By setting the meshing teeth 22 and the pawl 23, even if the power component 24 is lost, the slider 21 can maintain its position under the action of the pawl 23, thereby ensuring the tension of the transmission chain 3.

[0038] Specifically, this embodiment also includes a protective cover 1, which is disposed outside the transmission chain 3 and the chain plate 4, and two tensioning mechanisms 2 are respectively disposed on both sides of the protective cover 1.

[0039] Specifically, the end of the pawl 23 away from the meshing tooth 22 is rotatably connected to the protective cover 1, and the end of the pawl 23 near the meshing tooth 22 is tilted away from the other synchronous shaft 51.

[0040] Specifically, the top end of the protective cover 1 is configured as a feed pipe 11, and the bottom end of the protective cover 1 away from the feed pipe 11 is configured as a discharge pipe 12. The transmission direction of the top of the transmission chain 3 is from the feed pipe 11 to the discharge pipe 12.

[0041] Specifically, the chain plate 4 includes a connecting plate 41, a rotating plate 42, a stop block 411, and a pull rope 45. Two connecting plates 41 are provided, each connected to one of the two transmission chains 3. The rotating plate 42 is positioned between the two connecting plates 41, with one end of the rotating plate 42 facing the transmission direction of the transmission chain 3 rotatably connected to the two connecting plates 41. Two stop blocks 411 are fixedly connected to the two connecting plates 41 close to each other on both sides. The stop blocks 411 are positioned at the end of the rotating plate 42 facing away from the transmission direction of the transmission chain 3. When the chain plate 4 rotates to the top of the transmission chain 3, the rotating plate 42 is horizontal, and its bottom is supported by the two stop blocks 411. Two pull ropes 45 are provided, each corresponding to one of the two connecting plates 41. One end of each pull rope 45 is fixedly connected to the connecting plate 41, and the other end is connected to the rotating plate 42 so that the angle between the rotating plate 42 and the connecting plate 41 does not exceed 90°.

[0042] With the rotating plate 42 in place, when the conveyor chain 3 rotates to the top of the discharge pipe 12 and drives the chain plate 4 to rotate downward, the free end of the rotating plate 42 will rotate downward under the action of gravity, thereby pushing the sludge downward into the discharge pipe 12. When the rotating plate 42 tauts the pull rope 45 due to rotation, it will generate up-and-down vibration due to the instantaneous decrease in speed, thereby shaking off the sludge adhering to the rotating plate 42.

[0043] Specifically, the chain plate 4 also includes an auxiliary plate 43 and a limiting sleeve 44. The auxiliary plate 43 is disposed on the side of the rotating plate 42 near the stop block 411, and its length direction is along the width direction of the rotating plate 42. Both ends of the auxiliary plate 43 are connected to the ends of the two pull ropes 45, respectively. The limiting sleeve 44 is fixedly connected to the rotating plate 42. There are two limiting sleeves 44, which are respectively located on the rotating plate 42 near the two connecting plates 41. The auxiliary plate 43 passes through the two limiting sleeves 44. Several elastic protrusions 431 are fixedly connected to the side of the auxiliary plate 43 near the rotating plate 42, which are arranged along the length direction of the auxiliary plate 43.

[0044] By setting the auxiliary plate 43, when the pull rope 45 is taut, it will pull the auxiliary plate 43 to deform, causing the elastic protrusion 431 to impact the rotating plate 42 and generate vibration, which further allows the mud adhering to the rotating plate 42 to be shaken off more thoroughly.

[0045] Specifically, the auxiliary plate 43 is configured as an elastic auxiliary plate 43.

[0046] Specifically, the pull cord 45 is set as an elastic pull cord 45.

[0047] Specifically, the bottom of the inner cavity of the protective cover 1 is fixedly connected with several blocking protrusions 13 arranged along the transmission direction of the conveyor chain 3. When the chain plate 4 rotates to the bottom of the conveyor chain 3, the height of the downward tilting end of the rotating plate 42 is lower than the height of the top of the blocking protrusions 13. By setting the blocking protrusions 13, when the chain plate 4 moves at the bottom of the conveyor chain 3, the blocking protrusions 13 push the rotating plate 42 to continuously rise and then fall, and through multiple vibrations, the sludge on the rotating plate 42 can be completely shaken off.

[0048] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
