Double-V-shaped ditch construction device

Abstract

The invention provides a double-V-shaped ditch construction device, and belongs to the technical field of agricultural mechanisms. The double-V-shaped ditch construction device is characterized in that two sides of a copying central pressing plates of a shovel handle connecting frame are respectively synchronously embedded into six grooves which are symmetrically formed in the inner sides of two V-shaped soil extruding cutters; copying soil pressing plates are respectively fixedly connected to the outer sides of the two V-shaped soil extruding cutters; the end surface curves of copying bottom plates on the two copying soil pressing plates are the same as those of the copying central pressing plates; the edge curves of the two V-shaped soil extruding cutters are cissoid sections, and the sliding-cutting angles of the soil contact parts range from 40 to 50 degrees. The double-V-shaped ditch construction device is applicable to the mode of double-row planting in soybean ridges; two seed channels with smooth walls can be pressed and constructed on a seed bed, thus the influence of the seed channels on seed feeding can be reduced, the sliding-cutting resistance is small, and the penetrating performance is high; the V-shaped soil extruding cutters and the copying soil pressing plates co-extrude soil at two sides of the sidewalls of the soil extruding cutters so as to form V-shaped seed channels with firm and smooth walls, and as a result, oil returning of the sidewalls of the seed channels and wrinkling structures of the walls can be reduced; the variability of qualified seed-spaces can be reduced; the seeding quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a ditch opening or seed ditch building device for planting machinery. Background technique [0002] In recent years, high-efficiency and high-yield planting agronomy has become the focus of agricultural research. With the improvement of agricultural equipment and the promotion of fine farming technology, high-speed precision seeding with the goal of improving operational efficiency has become the main development direction of seeding technology. The high-yield planting technology of double row planting on soybean ridge refers to planting 2 rows of soybeans on a 60-65cm ridge with a row spacing of 10-15cm. This technology can make soybean plants evenly distributed on the ridge, ensure a relatively balanced absorption of water and fertilizer, and create a high-yielding soybean field group structure with good ventilation and light transmission in the field...

AI Technical Summary

Problems solved by technology

[0005] 1. Most of the groove-shaped cross-section is rectangular or trapezoidal, which has no clamping effect on the seeds and affects the uniformity of the particle distance

2. The wall of the seed ditch is not smooth and has the shape of "orange peel", which has a great impact on the quality of seeding
