A micro water and fertilizer control system for planting salt-tolerant esplanade grass

Abstract

This utility model discloses a micro water and fertilizer control system for planting salt-tolerant barnyard grass. During fertilization, a linkage mechanism drives the discharge plate to move downward, thereby opening the fertilizer outlet. The downward movement of the discharge plate drives the discharge rod to move downward, which in turn drives the spiral movement of the threaded sleeve, which in turn drives the spiral movement of the stirring sleeve, which in turn drives the spiral movement of the stirring blades, thereby stirring the fertilizer in the fertilizer storage tank. Through the cooperation of the discharge plate and the stirring blades, the fertilizer in the fertilizer storage tank can be stirred when the fertilizer outlet is opened and closed, thereby redispersing the fertilizer, reducing fertilizer clumping, improving fertilizer dissolution efficiency, reducing the probability of fertilizer outlet blockage, and improving the level of automation. After the discharge plate moves to the limit position, the stirring blades stop stirring, and the fertilizer continues to fall. The weight change of the fertilizer storage tank is monitored by a weight sensor until the weight of the fertilizer storage tank is reduced to a set weight.
