Straw displacement device in seed ditches of corn resowing cornfields

Abstract

The invention provides a straw displacement device in seed ditches of corn resowing cornfields, and aims to reduce the straw amount in the seed ditches. The production operation is low in cost and high in working efficiency. The device comprises a bracket and stalk opening components, wherein the bracket comprises a beam, a rear beam, pedals, a left longitudinal beam, a right longitudinal beam, and three supporting rods; two ends of the beam are respectively fixed with the left and right longitudinal beams through a base plate and bolts; the front end of each supporting rod is welded on the beam, and the rear end of each supporting rod is fixed with the rear beam through bolts; the three supporting rods are uniformly distributed along the beam and the rear beam of the bracket; the pedals are buckled on the longitudinal beams and are fixed by bolts; each stalk opening component comprises a fork and a rotating drum, wherein each fork comprises a fork arm, a fork handle and fork teeth; the two fork teeth of each fork are respectively welded at two ends of the corresponding fork arm; the lower end of each fork handle is welded with the corresponding fork arm; the upper end of the fork handle of each stalk opening component arranged on the beam of the bracket is fixed with the beam of the bracket through nuts; the upper end of the fork handle of each stalk opening component arranged on the rear beam is welded with a base plate which is fixed with the rear beam through bolts; the rotating drums sleeve the fork handles; the upper and lower ends of the rotating drums are fixed with the fork handles through nuts.

Description

technical field [0001] The invention relates to a straw displacement device for a seed ditch in a corn and wheat field for multiple sowing. Background technique [0002] In the irrigated land in the Huanghuai wheat region of my country, wheat-corn cropping twice a year is the main planting mode. Since the beginning of this century, with the large-scale application of compact and dense-resistant corn varieties, the planting density of corn in this region has increased by nearly 20% compared with the middle and late 20th century; The straw is left on the surface of the re-sowed wheat field. The integrated wheat rotary tillage sowing and suppression machine rotates a large amount of straw into the seed layer during the rotary tillage operation. During the sowing operation, the disc opener of the seeder (which is characterized by not easy to form congestion) The corn stalks in the sowing layer are "rotated and cut" into the seed ditch. The straw and soil in the seed ditch are h...

AI Technical Summary

Problems solved by technology

Burning straw, increasing the amount of sowing and irrigation after sowing, although it has a certain effect on improving the emergence rate and seedling rate of wheat and mitigating the secondary disasters in the later stage, it greatly increases the production cost of wheat and is not conducive to the fertilization of farmland soil.
