Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Take anti-blocking device scraper conveyor chain, including chain 1, 1 facial make-up of chain is equipped with scraper blade 2, and the vibrator 3 that can make 2 vibrations of scraper blade is installed to the both sides of chain 1.
The specific structure of the vibration device 3 comprises a bottom plate 301, a rotatable cam 302 is arranged on the bottom plate 301, the periphery of the cam 302 is an involute, and the cam 302 is driven by a servo motor. The bottom plate 301 is further provided with a first connecting rod 303 and a third connecting rod 305, the middle part of the first connecting rod 303 is rotatably connected with the bottom plate 301, and the upper end of the first connecting rod 303 is pressed against the cam 302. The upper end of the third link 305 is rotatably connected to the base plate 301. The lower ends of the first link 303 and the third link 305 are provided with a second link 304, and the second link 304 is rotatably connected with the first link 303 and the third link 305. The movable end of the second link 304 is provided with a striking head for striking the blade 2.
A spring assembly 307 is disposed between the first link 303 and the base plate 301, and the spring assembly 307 can press the upper end of the first link 303 against the cam 302. The specific structure of the spring assembly 307 includes: a first connector 3071 rotatably connected to the first link 303; the second connecting piece 3073 is rotatably connected with the bottom plate 301, the lower end of the second connecting piece 3073 is sleeved and inserted at the upper end of the first connecting piece 3071, and the second connecting piece 3073 can axially slide relative to the first connecting piece 3071; a pressure spring 3072 is arranged between the first connecting piece 3071 and the second connecting piece 3073.
