[0023] A guide rail 41 is welded to the bottom of the end plate 1 , a slide plate 42 is provided in the guide rail 41 , and a shaft slot 43 is provided on the side wall thereof so that the rotating shaft 31 can slide in the shaft slot 43 .
[0024] Both ends of the rotating shaft 31 pass through the shaft sliding grooves 43 on both sides and are respectively fitted with bearings 33 . The bearings 33 are mounted on the slide plate 42 so that the rotating shaft 31 can rotate stably. Two sprockets 32 are fitted on the rotating shaft 31 .
[0025] Two sets of driving mechanisms are respectively arranged on the guide rails 41 on both sides. The driving mechanism includes a hydraulic cylinder 51. A fixed seat 52 and a connecting seat 53 are respectively installed at both ends of the hydraulic cylinder 51. The fixed seat 52 is fixedly installed on the guide rail 41, and the connecting seat 53 is fixedly installed on the slide 42. By controlling the extension and contraction of the hydraulic cylinder 51, the slide 42 is driven to slide in the guide rail 41. When the slide 42 moves, it drives the synchronous movement of the bearing 33, the rotating shaft 31 and the sprocket 32, and then the chains on both sides are synchronously tensioned. Not only is the tensioning convenient and quick, saving time and effort, but it also avoids the problem of equipment failure caused by loose chains, thereby achieving long-term stable operation of the equipment.
[0026] It also includes a manual hydraulic pump station 7 installed on either side end plate 1. The oil outlet end of the manual hydraulic pump station 7 is connected to the oil inlets of the two hydraulic cylinders 51 through two oil inlet branches 11. The oil inlet end of the manual hydraulic pump is installed with an oil return pipe 9. A hand valve and a pressure gauge 8 are installed on the oil return pipe 9. The oil return pipe 9 is connected to the energy storage tank 6 through an energy storage pipe 61. The energy storage tank 6 is installed on the end plate 1. The energy storage tank 6 can store pressure and the value can be read intuitively through the pressure gauge 8.
[0027] The oil return main pipe 9 is connected to the oil return ports of the two hydraulic cylinders 51 through two oil return branch pipes 10. By operating the manual hydraulic pump, the two groups of hydraulic cylinders 51 can be controlled to work synchronously to achieve rapid tensioning of the chains on both sides.
[0028] During specific use, the utility model provides an automatic chain tensioning device for a manure drying machine. By pressing the handle on the manual hydraulic pump station 7, the two groups of hydraulic cylinders 51 are pressurized at the same time, so that the hydraulic cylinders 51 on both sides are synchronously extended, and then the slides 42, the rotating shaft 31 and the two sprockets 32 on both sides are driven to move synchronously, so that the chains on both sides are synchronously tensioned.
