Directional seeding device for super japonica rice seedling raising

Abstract

The invention discloses a directional seed metering device for a super japonica rice seedling and belongs to agricultural machinery. A first speed regulating motor, a second speed regulating motor, a driving roller assembly and a driven roller assembly are assembled on a frame assembly; horizontal conveyor belts are sleeved on the driving roller assembly and the driven roller assembly; two lateral plates are assembled at the upper end part of the frame assembly through a fixed bracket and a parallel four-rod inclination angle adjusting mechanism; rack seat boards with sawtooth racks are arranged at the inner sides of the two lateral plates through front and rear four-connecting rod drive mechanisms; V-shaped slideways are fixedly arranged on the part between the two lateral plates and above the rack seat boards; the sawtooth racks are arranged inside gaps at the bottoms of the V-shaped slideways; seed boxes and V-shaped seed metering plates are arranged at the left end parts and the right tail parts of the two lateral plates. By adopting the device, ordered regular arrangement of seed rice along the long axis direction is achieved; the accuracy of the seeding granularity of each hole is ensured by D-shaped movement tracks of the sawtooth racks; the directional seed metering device is good in operation quality, reliable to use, and fewer in faults.

Description

technical field [0001] The invention and creation belong to agricultural machinery, and mainly relate to a northern super japonica rice industrialized precision seedling planting equipment. Background technique [0002] The northern super japonica rice has high yield and high quality, and has strong tillering ability. The agronomic requirements for field planting are 2±1 robust seedlings per hole. Some of the existing precision seedling raising equipment in plug trays can achieve the sowing rate of 2 ± 1 seeds per hole. However, due to the irregular orientation of the seeds sown, homogeneous and robust seedlings cannot be cultivated, and the equipment structure is complex, so special bowl trays are required. However, although the traditional machine-transplanted blanket-shaped seedling raising and seedling planting equipment has a simple structure and low cost, it is difficult to achieve the sowing amount of 2 ± 1 seeds per sampling area, and it is even more difficult to mee...

Problems solved by technology

Some existing precision seedling raising equipment with plug trays can realize the sowing rate of 2±1 seeds per hole, but due to the irregular direction of the seeds sown, it is impossible to cultivate homogeneous and robust seedlings, and the equipment structure is complicated, so it needs to be equipped with a special pot. Although the traditional machine-inserted blanket-like seedling raising and sowing equipment has a simple structure and low cost, it is difficult to achieve the sowing rate of 2±1 seeds per sampling area, let alone the position accuracy and orientation of the sown seeds. Requirements, which restrict the large-scale application of northern japonica rice
