Description

Technical Field

[0001] The utility model relates to the technical field of scraper chains, and more specifically, to an automatic chain tensioning device for a dry sludge scraper. Background Art

[0002] In the dry sludge treatment process, the scraper is a commonly used conveying equipment. At the same time, as an important conveying equipment, the tension of the scraper chain is crucial to the normal operation of the equipment.

[0003] The chain of the scraper conveyor will become loose during long-term operation, affecting the normal operation of the equipment. At present, manual adjustment is usually used to tension the chain. This method is not only inefficient, but also difficult to ensure the adjustment accuracy. At the same time, as the equipment continues to run, the chain will gradually become loose due to wear, thermal expansion and contraction, and manual adjustment often cannot be carried out in time, which may lead to unstable equipment operation, affect the conveying efficiency of dry sludge, and may even cause equipment failure. Utility Model Content

[0006] The tensioning mechanism includes a motor, which is fixedly mounted on the top of the connecting plate, and the output end of the motor is fixedly connected to a chain take-up wheel, and the front side of the chain take-up wheel is fixedly connected to a driving pulley, and a secondary driven pulley is provided on one side of the driving pulley, and a transmission belt is connected between the driving pulley and the secondary driven pulley, fixed bearings are installed on both sides of the fixed plate, and a rotating shaft is installed between the fixed plate and the fixed bearing, and a transmission gear is installed on the front side of the fixed plate, and a transmission chain is connected between the transmission gear and the chain take-up wheel.

[0007] Preferably, the limiting mechanism includes an upper fixed shell, which is fixedly mounted on one side of the chain limiting frame, a lower fixed shell is fixedly mounted on the bottom of the upper fixed shell, and a plurality of support rods are fixedly mounted on the bottom of the chain limiting frame and the lower fixed shell.

[0009] Preferably, the fixed shaft is fixedly connected to the support column, and one end of the fixed shaft is fixedly connected to a limiting plate.

[0010] Preferably, the rotating shaft is rotationally connected to the fixed plate.

[0011] Preferably, the transmission chain is slidably connected to the inner wall of the chain limiting frame.

[0012] Preferably, the secondary pulley is fixedly connected to the rotating shaft.

[0013] Technical effects and advantages of this utility model:

[0014] 1. By setting up a tensioning mechanism, the motor drives the active pulley, which in turn drives the secondary pulley and the chain take-up wheel to rotate to achieve automatic chain tensioning. No human intervention is required for tedious manual adjustment, which greatly improves the automation level of the equipment, reduces labor costs and operating difficulty, and makes the operation of the dry sludge scraper more efficient and convenient. The motor can provide stable power output to ensure that the rotation speed and force of the chain take-up wheel are uniform. Through the precise transmission of the transmission belt and chain, the chain tension can be accurately controlled, avoiding the adverse effects on equipment operation caused by excessive or insufficient tension.

[0015] 2. By setting a limit mechanism and limiting the transmission chain through two limit plates, the chain is effectively prevented from becoming scattered during the winding process. This not only ensures the accuracy and stability of the chain transmission, but also prevents the chain from becoming entangled or interfering with other components due to scattering, reducing the probability of equipment failure and extending the service life of the equipment.
