Ground attaching sowing deep fertilization soil covering combined operation machine and method

Abstract

The invention discloses a ground attaching sowing deep fertilization soil covering combined operation machine and method in the technical field of agricultural machinery. The combined operation machine comprises an ascending and descending mechanism, wherein the ascending and descending end of the ascending and descending mechanism is fixedly connected with a seed fertilizer fixing frame; the front part of the seed fertilizer fixing frame is rotationally connected with a rotating shaft; a plurality of seed fertilizer furrowing cutters are distributed on the rotating shaft; each seed fertilizerfurrowing cutter comprises a seed furrowing part and a fertilizer furrowing part in integral arrangement; a sowing box, a fertilization box and a soil covering box are fixedly connected onto the seedfertilizer fixing frame arranged behind the seed fertilizer furrowing cutter; a plurality of soil covering openings are distributed at the bottom of the soil covering box; a plurality of sowing openings are distributed at the bottom of the sowing box; in the length direction, the two sides of the sowing openings are flushed with the two sides of the seed furrowing part; a fertilization opening isformed in the bottom of the fertilization box; the two sides of the fertilization opening are flushed with the two sides of the fertilizer furrowing part; an extrusion mechanism is arranged in the fertilization box; the extrusion mechanism comprises a plurality of first extrusion plate and second extrusion plates which can do reciprocating rectilinear movement and are arranged at two sides of thefertilization openings. The sowing fertilization depth can be ensured; the seed growth is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a compound operation machine and method for planting on the ground and applying fertilizer and covering soil. Background technique [0002] Traditional sowing and fertilizing of crops is generally done manually. With the development of technology, at present, sowing and fertilizing of crops has been widely realized by mechanical operation. Before sowing, ditches are made, seeds are sown in the ditch, and fertilization is applied after sowing. In the prior art, a Chinese invention patent with the patent name "a seeding and fertilizing machine" was disclosed. Its application date was 216.10.25 and its publication date was 2018.05.01. The invention includes a frame with a handle connected to one end of the frame , the front and rear sides of the bottom of the frame are respectively provided with a driving wheel and a pressing wheel, a sowing wheel is arran...
