No-tillage profiling precision seeder

Abstract

The invention discloses a no-tillage profiling precision seeder, which comprises a main rack. A fertilizer box is arranged on the main frame. A seeding rack is fixedly arranged in each seeding row below the main rack through a profiling four-link mechanism. A depth limiting wheel, a base fertilizer furrow opener, a seed furrow opener, a soil covering device, a compaction wheel, a seed box and a seed feeder are installed on each seeding rack. The internal part of the fertilizer box is divided into a front base fertilizer hopper and a rear seed fertilizer hopper. Base fertilizer feeders and seed fertilizer feeders are arranged at the bottoms of the front base fertilizer hopper and the rear seed fertilizer hopper at positions corresponding to each seeding row. Fertilizer feeding pipes below the base fertilizer feeders are communicated with the base fertilizer furrow openers. Fertilizer feeding pipes below the seed fertilizer feeders are communicated with the seed furrow openers. The no-tillage profiling precision seeder can adapt to and meet the requirements on seeding operation on sloping farmlands or uneven lands, can realize no-tillage precision seeding, and has the characteristics of consistent depth, high operation quality, strong adaptability, few fault and high use safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a no-tillage profiling precision seeder suitable for sowing operations on uneven fields in hilly and mountainous areas. Background technique [0002] Such as figure 1 Shown, be a kind of planter that uses most in the prior art, it comprises three parts of frame 1a, fertilizer applicator 2a and seeder 3a, when sowing operation, frame 1a is suspended on the suspension mechanism of tractor tail, The fertilizer applicator 2a is fixedly installed on the front part of the frame 1a, and the seeder 3a is fixedly installed on the rear part of the frame 1a, wherein there can be one or more fertilizer applicators 3a. [0003] The planter is simple in structure, low in cost, and completes one-time operation of sowing and fertilizing, and is suitable for supporting use of various large, medium and small tractors. Its disadvantage is that it is only suitable for fertilizing an...

Its disadvantage is that it is only suitable for fertilizing and seeding operations on flat fields

When working in an uneven field, the tractor will tilt back and forth, left and right due to changes in the terrain, and the frame 1a suspended at the tail of the tractor will tilt left and right as the tractor rises and falls. Since the seeder 3a is fixedly installed on the rear of the frame 1a Yes, the seeder 3a will also tilt up and down with the frame 1a, which will cause the seeder to sow in different depths, or even fail to sow, resulting in lack of seedlings and broken ridges, so this kind of seeder is not good in hilly areas. promotional use
