The invention relates to a
fertilizer application-
sowing-chemical spraying integrated
machine, belonging to the technical field of
agricultural machinery and equipment. The integrated
machine comprises a
machine frame, wherein the bottom of the machine frame is sequentially provided with road wheels, a furrowing machine, a furrow coverer, press wheels and a
film applicator from front to back; a drive unit, a gear box, a
fertilizer applicator, a
sowing box and a chemical
sprayer are sequentially arranged on the machine frame from front to back; a
fertilizer application
pipe is connected with the furrowing machine; the outlet of a
sowing pipe is positioned below the machine frame, and positioned between the furrowing machine and the furrow coverer; the furrow coverer and packing wheels are respectively connected with the machine frame through a first connecting rod; and the
film applicator is connected with the machine frame through a hydraulic transmission gear. The integrated machine is convenient to use, implements ditching, fertilizer application, sowing, furrow covering, press, film application, chemical spraying and many other operations at one time, has higher
automation degree, is simple to operate, reduces the operation frequency, enhances the operating efficiency, and lowers the labor force.
