The invention relates to the technical field of agricultural production, in particular to a
weedy rice spring ploughing and deep ploughing prevention and removal and
pesticide spraying all-in-one
machine, which comprises a ploughing device and a
pesticide applying device. The
pesticide applying device is arranged on the ploughing device. The pesticide applying device comprises a baffle and a
pipe fitting, the two ends of the
pipe fitting are rotatably installed on the two sides of the baffle, a plurality of rotary
tillage blades are fixedly connected to the
pipe fitting, the two ends of the
pipe fitting are coaxially communicated with a cylindrical thin-wall structure, and the outer
diameter of the thin-wall structure is larger than that of the
pipe fitting. A plurality of through holes are formed in the end face, close to the rotary
tillage blades, of the thin-wall structure, the pesticide applying device is used for filling the
pipe fitting with pesticide liquid, in the
seedling stage of the
weedy rice in spring, the
weedy rice is buried in the deep layer of soil through deep ploughing of the ploughing device to prevent growth of the weedy rice, and pesticide is sprayed through the pesticide applying device to inhibit growth of the weedy rice. The through holes are matched with the rotary
tillage blades, so that the pesticide can penetrate into the ground to inhibit the roots of the weedy rice.
