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...
