Embodiment Construction

[0038] Such as figure 1 , figure 2 As shown, the bionic surface disc fertilization ditch opener is installed on the fertilizer spreader through the installation holes, and the installation frame 1 is provided with 7 equidistant installation holes to adapt to the adjustment of the ditch depth under different operating conditions and ensure the smooth application of fertilizers.

[0039] Such as figure 2 , image 3 As shown, the bionic surface disc fertilization ditch opener consists of mounting frame 1, No. 1 curved disc 2, No. 1 fixing plate 3, No. 1 bearing chamber 4, No. 1 shaft 5, No. 1 shaft sleeve 6, No. 2 shaft sleeve 7. It consists of No. 2 shaft 8, No. 2 bearing chamber 9, No. 2 fixed plate 10, and No. 2 curved disc 11. Among them, the No. 1 fixed plate 3 is connected with the No. 1 curved disc 2 by 6 bolts, and is connected with the No. 1 bearing chamber 4 by 3 bolts. The bearing is installed and fixed in the bearing chamber. One end of the No. 1 shaft 5 interfer...

Abstract

The invention discloses a bionic curved-surface circular disc fertilization furrow opener. The bionic curved-surface circular disc fertilization furrow opener comprises a mounting frame, a curved-surface circular disc I and a curved-surface circular disc II, wherein the curved-surface circular disc I and the curved-surface circular disc II are mounted at the two sides of the mounting frame by shafts; the two curved-surface circular discs are mutually inclined and are mounted in an angular staggered manner; the curved-surface circular disc I and the curved-surface circular disc II have the same structures; the curved-surface circular disc I is composed of a plurality of curve-surface sector-shaped single bodies with the same structures; the curve-surface sector-shaped single bodies are tightly connected; and the outer edge of each curve-surface sector-shaped single body is of a tooth-shaped structure. According to the bionic curved-surface circular disc fertilization furrow opener, a disc surface adopts a bionic curved-surface structure and simulates shape characteristics of animal claws and toes, so that the soil digging performance is improved, the throwing rate is reduced, and capabilities of breaking stubbles and crushing soil are enhanced; the inner part of the disc surface is filled with annular nylon, and a water film structure at which the disc surface is in contact with the soil is damaged; and furrow opener cannot adhered to the soil and the passing ability of the furrow opener is enhanced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a bionic curved disc fertilization ditch opener. Background technique [0002] The function of the ditch opener is to open a seed ditch or a fertilizer ditch on the whole field, and introduce the seeds or fertilizer into the ditch, and its function has a great influence on the quality of sowing and seed germination. The openers are divided into two types: mobile and rolling. According to the size of the entry angle, the mobile openers are divided into acute-angle and obtuse-angle openers. The acute-angle opener penetrates the soil with its tip and has a strong ability to enter the soil. The obtuse angle opener is wedged into the soil by the edge of the tool, and penetrates into the soil by weight, and the trenching depth is relatively stable. The acute-angle opener has the function of raising the soil during ditching, turning up the wet soil in the low...
