No-till seeder

Abstract

The invention discloses a tillage-free seeder. A driver drives the tillage-free seeder to enter an edge of a farmland from a farm track, a piston of a hydraulic jack extends out to press a seeding roller to the ground; a tillage-free seeder engine drives a driving pulley to rotate through a hydraulic clutch, the driving pulley drives a driven pulley to rotate through a belt, the driven pulley drives a driving chain wheel to rotate, and the driving chain wheel drives a driven chain wheel to rotate through a chain, thereby driving the seeding roller to rotate; the seeding roller rotates forwards, and a hole-digging shovel on the seeding roller digs a pit; seeds fall in a seed divider from a funnel of a seed box; the seeds enter a concave pit in a rubber plate after penetrating a trapezoid hole of the seed divider and a corresponding small hole in an air drum under the trapezoid hole under the action of own gravity and wind pressure; the seeds in the concave pit in the rubber plate break through a stelliform gap in the concave pit of the rubber plate under the effect of the wind pressure, and then fall in the pit digged by use of the hole-digging shovel after penetrating a seeding pipe; the pit with the seed is filled and leveled, and a pressure roller tightly presses the filled and leveled pit.

Description

Technical field: [0001] The invention relates to a no-tillage seeder. Background technique: [0002] Invention patent application number: 201510114889.0, the invention patent name "A Spoke Type No-tillage Wheat Seeder" introduces a wheat seeder. The wheat seeder includes: a frame, a traction frame, ground wheels, and a seed box. The traction frame is installed at the front of the frame, the seed box is installed at the rear of the frame, and two ground wheels are symmetrically installed on both sides of the frame. One side of the ground wheel is provided with a sprocket coaxial with it, the sprocket is connected to the sorting disc through a chain to form a first chain transmission mechanism, and the sprocket forms a second chain transmission mechanism through a chain. The sorting disc is arranged below the frame, and a plurality of sorting discs are distributed side by side on the sorting disc, and the sorting disc is a disc. There is a cavity inside the sorting disc, an...

AI Technical Summary

Problems solved by technology

[0003] In the wheat seeder with this structure, the sorting disc, the sorting disc shaft and the rolling seeder are rusted, causing the friction between the sorting disc and the sorting disc shaft, between the sorting disc and the rolling seeder to increase, to accelerate wear

The sowing tube is small, and the wheat seeds are easily stuck in the center of the sowing tube when they slide down to the end of the sowing tube by the weight of the wheat seeds, and cannot fall down, causing no wheat seeds to be sown when the duckbill sower is opened

Even if the sowing tube is not stuck, the inner cavity of the duckbill sower can accommodate several wheat seeds. When the duckbill of the duckbill sower is opened, several wheat seeds will fall into the pit, wasting wheat seeds

The duckbill seeder has a complex structure and many moving parts, so it is easy to fail

For example: the return spring is rusted and loses its elasticity, the return spring is stuck with mud and cannot be reset, the two clips clamp the stone so that the duckbill planter cannot close its mouth, and the hinges of the two clips have mud dried and solidified. Make the duckbill seeder unable to open its mouth

The depth of the seeding tube inserted into the soil cannot be controlled. The no-tillage planter needs to turn around when it reaches the head of the field, and the no-tillage planter cannot stop planting when it is turned around.
