High-speed hilling disc

Abstract

The invention provides a high-speed hilling disc. The high-speed hilling disc mainly comprises a movable disc, front and rear separator belts, a fixed disc group, a soil opener group, a seeding mechanism, a stirring wheel mechanism, a wobble-plate mechanism and the like, wherein the soil opener group is uniformly distributed on the circumference of the movable disc; the fixed disc group is connected with the movable disc through a flange; the stirring wheel mechanism and the seeding mechanism are arranged on the right lower part of the fixed disc group; the wobble-plate mechanism is arranged at the rear lower part of the fixed disc group; and the front and rear separator belts are arranged in the fixed disc group. According to the high-speed hilling disc, by means of the design of irregular shapes of fixed disc and fixed disc cover and cantilever assembly of the soil opener group, the linear speed of the soil opener group can be improved, the seed falling time can be reduced, and the sowing speed can be accelerated; the seeding mechanism ensures the sowing accuracy by means of the front and rear separator belts and a forced feed agitator, and seeding wheels and seeds are protected by the design of a floating protective plate; the stirring wheel mechanism ensures seeds to enter the seeding mechanism smoothly; and the wobble-plate mechanism continues the opening state of the soil opener group to ensure the sowing quality, and enables the hilling disc to rotate clockwise and counterclockwise without influencing the sowing quality, so that the operability is improved.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery seeders, in particular to a high-speed hole sowing disc. Background technique

[0002] In the decades of seeding machine development, there have been various structural forms of hole seeding machines from ordinary hole seeders to precise air suction type, air blowing type, spoon wheel type, finger clip type, etc., without exception, these hole seeders All of them can complete the precise sowing operation of corn and other crops, but limited to the structural form and working principle of the machine tool itself, it cannot complete high-speed operation, the working efficiency is not high enough, and the structural form is complex, and the manufacturing process requirements are high. Under the situation of rising labor costs year by year, it is necessary to provide a hole seeder with high seeding speed and good seeding quality. Contents of the invention
