Description
Technical field
The utility model relates to graden machine, and more particularly, it relates to a kind of belt escapement of mower.
Background technology
Mower is mainly used in cutting the grass on a lawn and vegetation, and the kind of drive of existing mower is, by belt transmission, the power started is sent to driven pulley, driven pulley by rotating shaft mechanism by power transmission in blade, realize the action of chaffcutter.
Now retrieve one section of application number patent document mower disclosed in the China of 201420833274.4, in this patent document, specification [30] d section record belt slack is wrapped on driving wheel, directive wheel and driven pulley, regulating wheel can the surface of movable pressing belt, makes belt tension.Brake member can movable supporting with the surface of belt, to belt one resistance.
In above-mentioned patent document there is following defect in technical scheme:
Belt is placed between driving wheel and driven pulley, belt is in tensioning state for a long time in transmission process, and belt relaxation can occur, and the length of belt is increased, but because the spacing between driving wheel and driven pulley remains unchanged, therefore the belt automatic wheel place relaxed can be caused to depart from.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of belt escapement, and it can effectively prevent belt from departing from driving wheel, makes stable the operating at driving wheel of belt.
For achieving the above object, the utility model provides following technical scheme:
A kind of belt escapement, comprise belt, belt wheel and arrangement of clutch, described belt is placed on belt wheel, it is characterized in that, described arrangement of clutch is fixed with the anti-falling piece of band anti-drop block, described anti-drop block is placed in the both sides of belt wheel, leaves gap between described anti-drop block and belt, and described gap is less than the thickness of belt.
By adopting technique scheme, the driven pulley of V belt translation connects arrangement of clutch, and anti-falling piece is fixed on arrangement of clutch, and anti-falling piece is provided with multiple anti-drop block, and this anti-drop block can be column, rectangular-shaped etc.This anti-drop block is arranged in the outside of belt, the outer peripheral face namely formed during belt transmission.When lax belt departs from belt wheel in advance, because the gap between anti-drop block and belt wheel is less than the thickness of belt, make belt pass gap, can continue, in the running of belt wheel place, to play good anticreep effect, make the running that belt is stable.
Preferably, described anti-drop block is arranged in the intersection of belt and belt wheel.
By adopting technique scheme, the shake of belt and belt wheel intersection belt is comparatively large, is the easy slippage position of belt, arranges the anticreep effect that anti-drop block effectively improves anti-drop block, make the running that belt is stable in this position.
Preferably, the quantity of described anti-drop block is two, is placed in belt respectively and imports belt wheel place into and belt spreads out of belt wheel place.
By adopting technique scheme, due in V belt translation process, it is larger that belt imports the variation that position relationship that belt wheel place and belt spread out of the belt at belt wheel place occurs into, the belt of other positions or with belt wheel comprehensive engagement or be in vacant state, and link position changing greatly due to driving force, for there is the severely afflicated area that belt is tried to shirk responsibility, therefore import belt wheel place and belt at belt and spread out of position, 2, belt wheel place anti-drop block is set, effectively improve the anticreep effect of anti-drop block, effectively improve the belt escapement of V belt translation stability.
Preferably, described anti-falling piece is the connecting rod of knuckle more than, and the pars intermedia of this connecting rod is across belt wheel, and one end of described two anti-drop blocks is placed in the two ends of pars intermedia respectively.
By adopting technique scheme, belt wheel is installed on arrangement of clutch, due to the scrambling of arrangement of clutch shell, therefore by by connecting rod bending, need reach the needs adapting to diverse location environment.Connecting rod can be the metallic rod such as steel pole, rod of metal alloy or iron.The pars intermedia of connecting rod, across belt wheel, is placed in above belt wheel, and its effect plays buffer action to belt wheel, plays warning function, prevent unrelated person from arbitrarily touching belt wheel to unrelated person.
Preferably, the other end of described two anti-drop blocks is equipped with fixed part, and this fixed part is fixed on arrangement of clutch by screw.
By adopting technique scheme, anti-falling piece is fixed on arrangement of clutch by screw, be threaded relative to clamping etc. mode there is excellent fastening effect, effectively prevent anti-falling piece from loosening and cause the effect of anti-drop block to be lost efficacy, and effectively improve the anticreep effect of anti-drop block, effectively improve the belt escapement of V belt translation stability.Be threaded relative to welding etc. mode, there is good detachable performance, be convenient to remove anti-falling piece, to the maintenance of belt wheel.
Preferably, knee is provided with between described anti-drop block and fixed part.
By adopting technique scheme, this knee is convenient to anti-drop block and is adapted to different installation environments, makes anti-falling piece be convenient to install.
Preferably, described pars intermedia, anti-drop block and knee are placed in same plane, and described fixed part and described plane have angle.
By adopting technique scheme, pars intermedia, anti-drop block and knee are placed in same plane and effectively reduce space shared by anti-falling piece, be convenient to the installation of belt wheel, and conplane bent rod has good damping effect, be conducive to by the anti-falling piece of collision rift, Quick-return original position, effectively improves the anticreep effect of anti-drop block, effectively improves the belt escapement of V belt translation stability.Angle makes fixed part and knee misplace, and increases the usage space of instrument, is convenient to employee and screws screw.
Preferably, the scope 30 ° to 90 ° of described angle.
By adopting technique scheme, angle is less than 20 degree, and the dislocation space of formation is too small, and it is convenient to the lifting DeGrain that employee installs, therefore angle adopts 30 ° to 90 ° that have formation dislocation space larger.
The operation principle of this programme is: when lax belt departs from belt wheel in advance, because the gap between anti-drop block and belt wheel is less than the thickness of belt, make belt pass gap, can continue to operate at belt wheel place, play good anticreep effect, make the running that belt is stable.
