A device for preventing head and neck collision injuries for heavy agricultural vehicles

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of protective equipment for agricultural vehicles, in particular to a device for preventing head and neck collision injuries for heavy agricultural vehicles. Background technique [0002] Agricultural operation vehicles are also known as multi-purpose vehicles, which can complete various field operations such as plowing, sowing, fertilization, spraying, harvesting, etc., as well as mowing, loading, bulldozing and drilling, etc. Agricultural operations, and can be used for short-distance transportation (with a load of 1 to 2 tons) and as a fixed power source. The models of agricultural transport vehicles can vary with the area of ​​use, and most freight vehicles can be used for agricultural transport. Trucks or special-purpose vehicles are often used in areas with flat land, less land, simple crops, large transportation volume and long distances, and the proportion of medium-sized and heavy-duty trucks is gr...

AI Technical Summary

Problems solved by technology

[0003] In agricultural production, heavy-duty agricultural vehicles are necessary facilities. When the vehicle hits the front ridge, other hard objects or the vehicle itself is hit during the field work, the people inside the vehicle will be hit by inertia. Moving forward, but people will be pulled back to the back of the seat due to the sudden stop of the vehicle and the action of the seat belt, which can easily cause head and neck injuries such as concussions. It cannot provide effective protection for people in the case of vehicle collision and emergency stop of the vehicle, and it is very likely that the injury of the occupants inside the vehicle will be aggravated due to the inapplicability of the headrest, because the head and neck occupy a very large part of the entire body. The most important part, injuries to the head and neck are also very likely to cause paralysis of the entire body and even life-threatening
