The invention discloses a front-wheel steering and four-wheel steering switching mechanism of a plant protection chemical and fertilizer spraying machine. The front-wheel steering and four-wheel steering switching mechanism comprises a front axle, a rear axle, a front-wheel steering driving device, front wheels and rear wheels. Steering devices are arranged between the two sides of the front axle and the front-wheels as well as between the two sides of the rear axle and the rear wheels respectively. The steering driving device is arranged between the two front wheels, and a steering driving device is arranged between the two rear wheels. Each steering driving device comprises a power cylinder and steering tie rods, wherein the power cylinders are transversely arranged between the two front wheels as well as between the two rear wheels, and power cylinder bodies are fixedly connected to the rack or the front axle of the plant protection chemical and fertilizer spraying machine. The steering tie rods are arranged between the power cylinders and the steering devices. One end of the corresponding steering tie rod is connected with the end of a piston rod extending out of the power cylinder I body, and the other end of the corresponding steering tie rod is hinged to the corresponding steering device. The front-wheel steering and four-wheel steering switching mechanism is further characterized by being provided with a steering position sensing system. Front-wheel steering and four-wheel steering can be rapidly and reliably switched according to different requirements.
