Boat furrow forming device for synchronous furrowing in seeding

Abstract

The present invention discloses a boat furrow forming device for synchronous furrowing in seeding, comprising a plow post and a forming frame for mounting the plow post; the forming frame includes two soil breaker plates, two shaping plates and two soil flattening plates, intersecting curves of soil breaking surfaces of the two soil breaker plates are edge curves, and every two of the two soil breaker plates, the two shaping plates and the two soil flattening plates are arranged symmetrically along a plane of the edge curves; the edge curves are exponential function curves, and surfaces of the two shaping plates are each a plow body surface. Furrows are formed through the action of the soil breaker plates, shaping plates and soil flattening plates upon soil, multiple experiments show that made furrows are trapezoidal furrows having clean bottom, smooth walls and uniform depth, and soil reflow can be effectively inhibited; during operation for viscous heavy caked high-moisture-content soil, the boat furrow forming device shows good trafficability, blocking and adhesion during equipment and soil acting are overcome, and the boat furrow forming device is convenient to mount to a combine harvester for use.

Description

technical field [0001] The invention belongs to the technical field of farmland ditching tools in agricultural machinery, and in particular relates to a boat-shaped furrow forming device for synchronously digging furrows during sowing. Background technique [0002] There is a lot of rain in the southern part of my country, and the main agricultural production activities are carried out under the condition of high moisture content. During mechanized sowing operations, furrows for drainage or irrigation during droughts must be opened on both sides of the seedbed. Most of the cultivated land in the south is paddy field soil, in which clay particles account for a large proportion, and soil properties vary greatly with water content. Many furrowing and ridging machines used in northern regions cannot be used for furrowing and furrowing operations in southern soil. At present, there are two main ways of mechanized furrowing in southern farmland: one is to use the active rotary di...

Problems solved by technology

[0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned technologies, and to solve the problems that the power of the tractor cannot be rationally utilized when the combined seeder opens the ditch, the ditching resistance is large, and the ditch type is not easy to ensure. The boat-shaped furrow forming device can effectively inhibit soil backflow and meet the requirements of crop planting furrows
