Description

Double disk opener

Technical field

The utility model relates to a kind of double disk opener, belongs to technical field of seeders.

Background technology

The disk coulter that is used for wheat seeder, mostly constitute by two isometrical disks, two disks are installed on the column by bearing, fertilizer guiding tube and grain conductor are arranged in two disks, its sowing fertilizer of the plough of this structure is executed for mixing with layer colleague, causes seed manure with executing the burning seedling problem that causes.For this reason, by big or small disc structure, reach the purpose that seed manure gives.But this structure is installed in fertilizer guiding tube and grain conductor on the column, the defertilizing opening of fertilizer guiding tube and the substantially parallel setting of the sowing port of grain conductor, only separate by a flexible seeds protecting plate, exist complex structure, install loaded down with trivial details, especially fertilizer guiding tube and grain conductor are approaching, can not reach the effect that seed manure gives fully.

Summary of the invention

The purpose of this utility model provides a kind of rational in infrastructure, easy for installation, can keep seed manure to give the double disk opener of effect.

The utility model is that the technical scheme that achieves the above object is: a kind of double disk opener, comprise V-shaped and two big disk and roundels that diameter does not wait, it is characterized in that: also have support, support is provided with crossbeam and inner perpendicular fertilizer cavity and the seeding cavity of putting, big disk and roundel are installed in the both sides of support respectively, fertilizer cavity on the support is positioned at the front portion of seeding cavity, frame bottom is equipped with two siphunculus, defertilizing tube on the two siphunculus and discharging tube communicate with fertilizer cavity and seeding cavity in the support respectively, the sowing port of discharging tube is positioned at roundel one side, the defertilizing opening of defertilizing tube is positioned at big disk one side, and the sowing port of discharging tube is higher than the defertilizing opening of defertilizing tube.

Fertilizer cavity in the utility model support and seeding cavity are by being provided with before and after the direct of travel, and the sowing port that is installed in the defertilizing opening of the defertilizing tube on the frame bottom two siphunculus and discharging tube is height setting, and be partial to big disk and roundel respectively, therefore greatly, during the roundel trench digging, it is little to stir the soil amount, fertilizer can be fallen darker position along the big disk inwall, seed is fallen more shallow position along the roundel inwall, difference by the disk size is buried fertilizer through the roundel side clearance soil of backflow rapidly, fertilizer and seed are mixed to be dropped on together, the effect that can keep seed manure to give has solved seed manure well with executing the burning seedling problem that causes.The utility model is rack-mount with big disk and roundel, and fertilizer cavity and seeding cavity are set on the support, and is rational in infrastructure, compact, easy for installation.
