[0001] This utility model relates to the technical field of chain plate chip conveyors, specifically to a chain plate chip conveyor sprocket tensioning structure. Background Technology
[0002] Chain conveyor is a high-efficiency waste chip conveying device. Its working principle is based on the combined movement of chains and chain plates on both sides, with the chain plates moving through the rotation of sprockets. In practical use, it has been found that in order to obtain better conveying effect, the chain needs to be tensioned; therefore, a sprocket tensioning structure is required.
[0003] Patent CN204083102U describes a sprocket tensioning device, which consists of a lever tensioning assembly and a sprocket adjustment device. One end of the sprocket adjustment device is fixed to the frame, and the other end of the sprocket adjustment device is hinged to one end of the lever tensioning assembly by bolts. The other end of the lever tensioning assembly corresponds to the position of the chain, and the hinge point in the middle of the lever tensioning assembly is fixed to the frame.
[0004] The sprocket tensioning device can only adjust the tension of a single chain, while the chain plate chip conveyor has two symmetrical chains, making it difficult to adjust the tension of the chain plate chip conveyor. Utility Model Content
[0005] The purpose of this invention is to provide a chain plate chip conveyor sprocket tensioning structure, which achieves a tensioning effect by using a hydraulic cylinder to push the driven wheel assembly to move synchronously at both ends.
[0006] To achieve the above objectives, this utility model provides a chain plate chip conveyor sprocket tensioning structure. This structure includes a driven wheel assembly mounted at the end of the chain plate chip conveyor frame. The driven wheel assembly includes sliders at both ends, and a driven shaft rotatably connects the two sliders. Driven sprockets are fixedly fitted at both ends of the driven shaft. The sliders are configured to slide horizontally on the chain plate chip conveyor frame. The rear sides of the two sliders are connected by a connecting plate, which has a through-type section. The chain plate chip conveyor frame has an elongated hole with guide grooves on its upper and lower sides. A fixed crossbeam is located behind the connecting plate inside the chain plate chip conveyor frame. A swing arm is rotatably mounted inside the fixed crossbeam. Cylindrical protrusions that slide in the guide grooves are provided on the upper and lower sides of the front end of the swing arm. A vertically penetrating elongated hole is provided at the rear end of the swing arm. A sliding pin is provided inside the elongated hole. A hydraulic cylinder is fixedly connected to the outside of the chain plate chip conveyor frame. The cylinder shaft of the hydraulic cylinder extends vertically into the chain plate chip conveyor frame and is connected to the sliding pin.
[0007] Preferably, the fixed crossbeam has a rectangular hole that runs through the front and back, a fixing pin is provided in the rectangular hole, and the swing arm has a fixing hole in the middle for fitting the fixing pin.
[0008] Preferably, the end of the chain plate chip conveyor frame is provided with a rectangular sliding hole that runs through the left and right sides, and the slider is slidably disposed in the rectangular sliding hole along the length direction of the chain plate chip conveyor frame.
[0009] Preferably, the upper and lower sides of the rectangular sliding hole are provided with sliding grooves, and the upper and lower sides of the slider are provided with sliding strips corresponding to the sliding grooves.
[0010] Preferably, the end of the rectangular sliding hole is set as an open opening, which is covered by a cover plate, which is installed at the end of the chain plate chip conveyor frame by multiple bolts.
[0011] Preferably, the slider is embedded with a bearing, and both ends of the driven shaft are mounted in the bearing.
[0012] Preferably, the front end of the chain plate chip conveyor frame is provided with a drive wheel assembly;
[0013] The drive wheel assembly includes a drive shaft driven by a motor and drive sprockets sleeved at both ends of the drive shaft and rotating synchronously with the drive shaft.
[0014] According to the above technical solution, this utility model provides a chain plate chip conveyor sprocket tensioning structure. This chain plate chip conveyor sprocket tensioning structure includes a driven wheel assembly installed at the end of the chain plate chip conveyor frame. The driven wheel assembly includes sliders disposed at both ends, and a driven shaft is rotatably disposed between the two sliders. Driven sprockets are fixedly sleeved at both ends of the driven shaft. The sliders are configured to slide horizontally on the chain plate chip conveyor frame. The rear sides of the two sliders are connected by a connecting plate, and the connecting plate has a through-type section. The chain plate chip conveyor frame has an elongated hole with guide grooves on its upper and lower sides. A fixed crossbeam is located behind the connecting plate inside the chain plate chip conveyor frame. A swing arm is rotatably mounted inside the fixed crossbeam. Cylindrical protrusions that slide in the guide grooves are provided on the upper and lower sides of the front end of the swing arm. A vertically penetrating elongated hole is provided at the rear end of the swing arm. A sliding pin is provided inside the elongated hole. A hydraulic cylinder is fixedly connected to the outside of the chain plate chip conveyor frame. The cylinder shaft of the hydraulic cylinder extends vertically into the chain plate chip conveyor frame and is connected to the sliding pin.
[0015] When the sprocket tensioning structure of this chain plate chip conveyor is tensioned, the hydraulic cylinder pushes the swing arm to swing left and right. At this time, the sliding pin slides passively in the elongated hole. As the swing arm swings, the cylindrical protrusion at the front end of the swing arm slides in the guide groove, thereby pushing the connecting plate to move back and forth. With the sliding cooperation between the slider and the chain plate chip conveyor frame, the connecting plate slides stably, thereby driving the driven shaft and driven sprocket installed between the sliders to move back and forth, achieving the tensioning effect.
[0016] The chain plate chip conveyor's sprocket tensioning structure differs from the traditional method that relies solely on rotating a screw to adjust the tensioning position on both sides. It is more convenient, requiring only one hydraulic cylinder for adjustment. Furthermore, the hydraulic cylinder is located outside the chain plate chip conveyor frame, making maintenance easier.

Detailed Implementation
[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0025] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.
[0026] See Figure 1-3 The chain conveyor sprocket tensioning structure shown includes a driven wheel assembly installed at the end of the chain conveyor frame 1. The driven wheel assembly includes sliders 4 at both ends, and a driven shaft 10 is rotatably connected between the two sliders 4. Driven sprockets 19 are fixedly sleeved at both ends of the driven shaft 10. The sliders 4 are configured to slide horizontally on the chain conveyor frame 1. The rear sides of the two sliders 4 are connected by a connecting plate 7. The connecting plate 7 has a through-hole 21, and guide grooves 9 are provided on the upper and lower sides of the through-hole 21. A fixed crossbeam 6 is provided inside the chain plate chip conveyor frame 1 behind the connecting plate 7. A swing arm 11 is rotatably provided inside the fixed crossbeam 6. The upper and lower sides of the front end of the swing arm 11 are provided with cylindrical protrusions 20 that slide in the guide groove 9. The rear end of the swing arm 11 is provided with a vertically penetrating elongated hole 14. A sliding pin 23 is provided inside the elongated hole 14. A hydraulic cylinder 12 is fixedly connected to the outside of the chain plate chip conveyor frame 1. The cylinder shaft 13 of the hydraulic cylinder 12 extends vertically into the chain plate chip conveyor frame 1 and is connected to the sliding pin 23.
[0027] When the chain plate chip conveyor sprocket tensioning structure is tensioned, the hydraulic cylinder 12 pushes the swing arm 11 to swing left and right. At this time, the sliding pin 23 slides passively in the elongated hole 14. As the swing arm 11 swings, the cylindrical protrusion 20 set at the front end of the swing arm 11 slides in the guide groove 9, thereby pushing the connecting plate 7 to move back and forth. Under the sliding cooperation between the slider 4 and the chain plate chip conveyor frame 1, the connecting plate 7 slides stably, thereby driving the driven shaft 10 and the driven sprocket 19 installed between the sliders 4 to move back and forth, achieving the tensioning effect.
[0028] The chain plate chip conveyor's sprocket tensioning structure differs from the traditional method that relies solely on rotating a screw to adjust the tensioning position on both sides. It is more convenient, requiring only one hydraulic cylinder 12 to drive the adjustment. Furthermore, the hydraulic cylinder 12 is located outside the chain plate chip conveyor frame 1, making it easy to maintain.
[0029] In this embodiment, a rectangular hole 15 extending through the front and rear is provided in the middle of the fixed crossbeam 6, and a fixing pin 22 is provided in the rectangular hole 15. A fixing hole for fitting the fixing pin 22 is provided in the middle of the swing arm 11. This arrangement provides a rotating connection method between the swing arm 11 and the fixed crossbeam 6.
[0030] In this embodiment, a rectangular sliding hole 2 extending through the left and right sides is provided at the end of the chain plate chip conveyor frame 1, and the slider 4 is slidably disposed within the rectangular sliding hole 2 along the length direction of the chain plate chip conveyor frame 1. This arrangement provides a sliding connection method between the driven wheel assembly and the end of the chain plate chip conveyor frame 1, improving sliding stability.
[0031] In this embodiment, the upper and lower sides of the rectangular sliding hole 2 are provided with sliding grooves 5, and the upper and lower sides of the slider 4 are provided with sliders corresponding to the sliding grooves 5. This arrangement increases the sliding stability of the slider 4 through the cooperation between the sliding grooves 5 and the sliders.
[0032] In this embodiment, the end of the rectangular sliding hole 2 is set as an open opening, which is covered by a cover plate 3. The cover plate 3 is installed at the end of the chain plate chip conveyor frame 1 by multiple bolts. This arrangement facilitates opening the end of the rectangular sliding hole 2, making disassembly and maintenance easier.
[0033] In this embodiment, the slider 4 is fitted with a bearing 8, and both ends of the driven shaft 10 are mounted in the bearing 8. This arrangement increases the smoothness of the rotation of the driven shaft 10.
[0034] Furthermore, the front end of the chain plate chip conveyor frame 1 is provided with a drive wheel assembly; the drive wheel assembly includes a drive shaft 17 driven by a motor 16, and drive sprockets 18 sleeved on both ends of the drive shaft 17 and rotating synchronously with the drive shaft 17.
