[0002] A fertilizer spreader refers to a machine for spreading fertilizers, which is composed of a fertilizer box, a fertilizer dispenser, etc. Some of them also have fertilizer conveying, ditching, and covering devices. In order to check the uniformity of fertilization, most existing fertilizer spreaders install detection sensors at the bottom of the fertilizer spreader for detection. However, most of the detection sensors installed at the bottom of existing fertilizer spreaders do not have a protection function, which can easily lead to the detection sensors being squeezed and collided with foreign objects on the ground when the fertilizer spreader drives the detection sensors to move, causing damage, thereby failing to meet customer usage needs. For this reason, we propose an external protection structure for the detection sensor of a fertilizer spreader to solve the above problems. Utility Model Content
