The invention discloses an excavator seat unpowered ventilation device, which belongs to the technical field of excavator equipment, and comprises a seat surface and a ventilation air bag, a hollow cavity is formed in the seat surface, and the ventilation air bag is mounted in the hollow cavity; an upper through opening which corresponds to the ventilation air bag air opening and is communicated with the outside is formed in the upper portion of the hollow cavity, and a lower through opening which corresponds to the ventilation air bag air opening and is communicated with the outside is formed in the lower portion of the hollow cavity; sponge is arranged on the outer side face of the ventilation air bag, and the ventilation air bag is fixedly arranged in the excavator seat through the sponge; a driver sits in the seat of the excavator so as to apply pressure to the sponge of the seat and the ventilation air bag, the ventilation air bag compresses air in the ventilation air bag after being stressed, the air is exhausted from the air opening of the ventilation air bag, and external air is supplemented into the ventilation air bag again during rebounding; by means of the characteristics of the air bag, the air bag conducts reciprocating air circulation along with the swing change of a driver or a vehicle body, and therefore the unpowered seat ventilation effect is achieved.
本发明公开了一种挖掘机座椅无动力通风装置,属于挖掘机设备技术领域,包括:座椅椅面、通风气囊;座椅椅面中开设有中空腔体,通风气囊安装在中空腔体中;中空腔体的上方开设有与通风气囊风口对应且与外界连通的上方通口,中空腔体的下方开设有与通风气囊风口对应且与外界连通的下方通口;通风气囊的外侧面上设有海绵,并通过海绵固定设置在挖掘机座椅中;驾驶员坐于挖掘机座椅中从而向座椅的海绵和通风气囊施加压力,通风气囊受力后压缩通风气囊内的气体,使得气体从在通风气囊风口排出,并在回弹时重新将外界气体补充入通风气囊;本发明利用气囊特性使得气囊随驾驶员或车身摆动的变化进行往复的气体流通循环,从而实现无动力的座椅通风效果。
