The invention relates to the technical field of agricultural vehicle protection equipment. The invention further discloses a device capable of preventing the head and the neck from being collided andinjured for a heavy agricultural vehicle. The device comprises a first shell and a second shell. A pressing plate is movably connected to the interior of the first shell, non-Newtonian fluid is movably connected to the bottom of the pressing plate, a first spring is fixedly connected to the bottom of the pressing plate, a pull rope is movably connected to the bottom of the pressing plate, and a fixed pulley is movably connected to the exterior of the pull rope. Under the interaction of the first shell, the pressing plate, the non-Newtonian fluid, the first spring, the pull rope, the fixed pulley and a safety belt, when a person in the vehicle are subjected to external impact or other acting forces, the person protected by the safety belt carries the safety belt to move forwards, so that non-Newtonian fluid in the first shell is converted into colloid from fluid, a contact is triggered, a rear protection device can be started rapidly, the effect of timely feedback is achieved, and the prerequisite condition of reducing harm to people in the back of vehicle is also provided.
本发明涉及农业车辆防护设备技术领域,且公开了一种用于重型农业车辆可防止头颈部碰撞受伤的装置,包括外壳一和外壳二,所述外壳一的内部活动连接有压板,压板的底部活动连接有非牛顿流体,压板的底部固定连接有弹簧一,压板的底部活动连接有拉绳,拉绳的外部活动连接有定滑轮;通过外壳一、压板、非牛顿流体、弹簧一、拉绳、定滑轮、安全带之间的相互作用下,可以使得当车内人员当受到外界撞击或者其他的作用力时,被安全带保护的人员带着安全带向前运动,这样就会使得外壳一中的非牛顿流体从流体状转变成胶体状,从而触发触点,这样就会比较快速的启动之后防护装置,起到了反馈及时的作用,也为之后的车内人员减少伤害的先决条件。
