The patent number is CN 201520077191.1's national utility model patent discloses an excavator seat, the seat, including back, regulator, seatpad, headrest, sponge, massager, well medicine bag, heater, pivot, gasbag and mount table, the back lower extreme passes through the regulator and connects the seatpad right-hand member, the headrest is installed to the back upper end, the sponge has all been filled to back and seatpad inside, the inside massager that is provided with of sponge of back, well medicine bag is installed in the massager left side, the inside heater that is provided with of sponge of seatpad, the gasbag is connected through the pivot in the middle part of the seatpad downside, the gasbag is fixed on the mount table. Although the seat is comfortable and has a large number of functional categories, the above solution has the following problems and disadvantages: because the air bag is arranged between the lower part of the rotating shaft and the mounting table, the seat cushion is lifted by filling air into the air bag, and because the air bag is arranged at the lowest part, the whole structure is unstable during inflation, and the air bag bears more load and has higher danger; the seat adapts to the driving comfort of different drivers by adjusting the angle of the backrest, but does not consider the comfort of the drivers when the drivers have a rest in the cab.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides an excavator seat damping device, its simple structure, the fixity is strong, and the shock attenuation is effectual, the better comfort level requirement that has satisfied.
In order to achieve the above object, the utility model adopts the following technical scheme:
an excavator seat cushioning device comprising: the seat, the bolt fixed connection backup pad is passed through to the seat bottom, the bolt fixed connection base is passed through to the backup pad below, the base both sides all are equipped with slot one, the inboard bolt fixed connection support column that passes through of slot one, the support column outside is around establishing damping spring one, damping spring one bottom fixed connection fixes the fixed plate on the excavator, and the fixed connecting axle of wearing to establish between two fixed plates, the base both sides all are equipped with slot two, pass through the bolted connection spliced pole in the slot two, the articulated connecting rod in spliced pole bottom, the articulated sleeve in connecting rod bottom, the sleeve cover is established on the connecting axle, and fixed connection is around establishing the damping spring two in the connecting axle outside between two sleeves.
Furthermore, the two slots II are positioned between the two slots I, and the slots I are integrally connected with the surrounding sheet positioned on the outer circumference of the supporting column.
Further, the bottom ends of the supporting columns do not contact the fixing plate.
Further, the sleeve upper end integrated into one piece is connected with the arc piece articulated with the connecting rod, be equipped with the perforation on the arc piece.
Further, the connecting shaft and the sleeve are in frictionless contact.
The utility model has the advantages that:
the seat is under driver's action of gravity, the seat pushes down, the support column downstream, damping spring one compresses downwards, because spliced pole bottom articulates the connecting rod, the articulated sleeve in connecting rod bottom, damping spring two compression between the sleeve, damping spring one and damping spring two all have the effect of restoring force, realize the shock attenuation, and the integrated device fastness is good, the shock attenuation effect is lasting, long service time, its simple structure, the fixity is strong, the shock attenuation is effectual, the better comfort level requirement of having satisfied.
