The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Embodiment
As shown in Figures 1 to 3, a kind of novel chain of en-masse conveyor automatic tensioning mechanism, it includes flight chain 1, tightening device 5, tail wheel 2, trough 7, flight chain 1, great wheel, tail wheel 2, trough 7 and driving device are prior art, that is: tail wheel 2 is placed in one end of trough 7, flight chain 1 is centered around between tail wheel 2, and the power intake of driving device is connected with great wheel, driving device can but be not limited to the motor with reductor.
Can automatically adjust flight chain tensioning degree for realizing, contriver proposes a kind of novel chain of en-masse conveyor automatic tensioning mechanism on the stretching device basis of existing slat conveyer, and tightening device 5 wherein has following structure:
When normal work, elastomeric element 5-6, by cover, screw mandrel, 1# connecting panel, passes to tail wheel by power.So, effectively automatically regulate the tensioning degree of scraper plate sprocket wheel by adjusting the relative position of tail wheel.Elastomeric element can but be not limited to spring, rubber, at this preferred spring.Spring, for Rubber Parts, its elastic displacement is large, and the adjusting displacement of tail wheel is also large.
The tightening device 5 that adopts said structure, elasticity of demand parts have enough large elastic force, require this elastic force to be not less than the resistance occurring in slat conveyer course of conveying, and this have great difficulty.For reducing difficulty, contriver further proposes on aforementioned basis: on aforementioned 1# connecting panel 3, be connected with tooth bar 5-4; Aforementioned trough 7 is also provided with stopping device 6, and the body of stopping device 6 is 2# connecting panel 6-1, and 2# connecting panel 6-1 one end is provided with hook 6-2, and the 2# connecting panel 6-1 other end is provided with hole 6-3, and 2# connecting panel 6-1 is fixed on described trough 7 by the axle through hole 6-3.Increase after this structure, the hook on 2# connecting panel just can catch on tooth bar, thereby for 1# connecting panel provides auxiliary force, finally guarantees the tensioning degree of scraper plate sprocket wheel.Aforementioned tooth bar preferably: the tooth on tooth bar 5-4 is towards described tail wheel one side.This structural controllability tail wheel processed, only to a lateral movement, guarantees the tensioning degree of scraper plate sprocket wheel.
