Description

一种履带式谷物联合收割机浮筏式驾驶座椅结构 技术领域
本发明属于联合收割机驾驶座椅结构制造领域，尤其是涉及一种履带式谷物联合收割机浮筏式驾驶座椅结构，可广泛安装于各类履带式谷物联合收割机驾驶台上。
背景技术
目前国产履带式谷物联合收割机主要采用开放式驾驶台，较多的发明和技术也主要是在开放式驾驶台上进行改进和完善，如专利CN201410081085.0公布了一种联合收割机的驾驶台，通过将离合器手柄前端设置成往上翘一定的角度并将将驾驶座椅与前操纵塔进行梯形状设计，提高操作的安全性及有效地避驾驶作业员往后倾倒的危险。专利CN201410081419.4公布了一种联合收割机的驾驶室座椅，通过对座椅位置设计实现座椅前后、上下调节的功能。专利CN201610602990.5公开了一种收获机座椅总成，通过对座椅靠背骨架前后调节和角度倾斜，可以适合不同操作者以及不同坐姿的需求。但履带式谷物联合收割机田间收获时行走底盘受田间凹凸不平路、面激振、滚筒脱粒过程中因喂入量变化引起冲击、整机上多回转体激振耦合等均引起整机的强烈振动，驾驶员在操作联合收割机工作时也受到振动的影响甚至危及驾驶操作人员的身心健康。
为减少履带式谷物联合联合收割机田间工作时机体振动对驾驶操作人员的影响，在驾驶操作或驾驶座椅结构上也进行了一些减振设计及改进。专利CN201510239705.3公开了一种履带式联合收割机浮动驾驶操纵台，通过设计三级减振部分与底盘机架和座椅相连，对竖向振动进行三层缓冲和衰减。专利CN201620205849.7公开了一种收割机座椅总成，能够实现对座椅的快速定位固定，使操作者能够实现扶手架与座椅的快速切换。目前对履带式谷物联合联合收割机驾驶座椅的减振方法主要是竖向一级或者多级减振，但无法解决驾驶座椅所受的横向振动干扰；现有采用竖向一级或者多级减振系统可以等效为一级性能更好的减振器，但始终难以消除整机收获中多方向激振力对座椅引起的振动。
