Description

Prevent direct injection guider of discrete type of seed

Technical Field

The utility model relates to a seed field of scattering especially relates to a prevent direct broadcast of seed discrete type and spray guiding device.

Background

The development of science and technology brings the change of the people's life in the ground. In the aspect of agriculture, the original condition of manual seeding is gradually changed to be replaced by automatic equipment. Manually operated equipment such as early seeders, rice transplanters and the like gradually develop into operations from a man-made plane to an unmanned plane, which greatly improves the production efficiency. At present, in the aspect of the seed is sowed, although adopt unmanned aerial vehicle can greatly promote efficiency, however, because unmanned aerial vehicle's characteristic, the air current that unmanned aerial vehicle's screw produced can produce very big influence to the whereabouts orbit of seed in the seeding process, can lead to the seed to fall scattered in disorder not have the chapter when ground under the general condition, can't reach the precision planting with equipment such as adoption seeder, transplanter at all. At present, a guiding pipe is adopted to guide and blow the seeds to the ground through wind power so as to reduce the influence of air turbulence generated by a propeller of the unmanned aerial vehicle on the falling track of the seeds. However, this structure still cannot be made absolutely precise, and the planting point of the seed is still difficult to control. The reason for this is that the seeds are driven by the wind in the guide tube to shoot towards the ground when being discharged from the seed metering device on the unmanned aerial vehicle, and when the wind in the guide tube flows to the exit of the guide tube, turbulent eddy current is generated at the exit of the guide tube due to the pressure difference between the pressure in the guide tube and the peripheral pressure, so that the seeds still deviate when being discharged from the exit of the guide tube, and the landing track of the seeds still cannot be controlled. The above problems are preferably solved if a device is designed to reduce the effect of turbulent eddies at the exit of the guide tube on the seed.

SUMMERY OF THE UTILITY MODEL

the utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, greatly improve the direct injection guiding device of preventing seed discrete type of the orbit precision that falls to the ground when the seed is planted and is broadcast.

the utility model adopts the technical proposal that: the utility model discloses a guide tube body, be provided with the exit port on the guide tube body exit port department encircles the guide tube body is provided with prevents that the dispersion encloses the fender, prevent that the dispersion encloses and is provided with the ventilative clearance on keeping off, prevent that the dispersion encloses the length direction that keeps off with the axis direction of guide tube body is unanimous.

The anti-dispersion enclosure is arranged at the exit port of the guide tube body, so that seeds can be prevented from splashing to the periphery when being emitted to the exit port from the guide tube body, the seeds can be limited in the range of the enclosure and continuously fall down through the anti-dispersion enclosure, the precision of the seeds in direct sowing is effectively improved, the anti-dispersion enclosure is provided with the ventilation gap, circumferential turbulence can be effectively released at the exit port by airflow jetted from the guide tube body, the downward airflow continuously pushes the seeds to fall down to the ground, the landing track precision of the seeds in direct sowing is greatly improved, and the seeds are accurately sowed.

Furthermore, the anti-dispersion enclosure is composed of a hollow plastic cover provided with a gap, and the gap is a long strip-shaped gap or a round hole-shaped air outlet; or the anti-dispersion enclosure is formed by an array of bristles.

According to the scheme, the anti-dispersion enclosure can be made of different materials according to different seeding types, so that the adaptability is improved, and if the seeds which are easy to damage are made of soft bristles with better softness, the anti-dispersion enclosure is made; and when the seeds are not easy to be damaged, the anti-dispersion enclosure can be made of materials with lower cost.

Further, the bristles are plastic bristles or elastic fiber filaments. Therefore, the selection of the bristles is also various, and other types of bristles can be selected according to actual needs.

Still further, the length of the anti-dispersion enclosure is 50-500 mm. Therefore, the length of the anti-dispersion enclosure is adjustable, and the seeds emergent from the guide tube body can be enclosed in different strokes, so that different seeding requirements are met.

FIG. 2 is a simplified structural schematic diagram of one of the structural forms of the anti-dispersion fence;

Fig. 3 is a simple structural schematic diagram of another structural form of the anti-dispersion enclosure.

Detailed Description

As shown in fig. 1, the present invention comprises a guide tube body 1, wherein the guide tube body 1 is formed by sleeving a plurality of sleeves. An exit port 2 is arranged on the guide tube body 1, an anti-dispersion surrounding baffle 3 is arranged at the exit port 2 and surrounds the guide tube body 1, and the length of the anti-dispersion surrounding baffle 3 is 50-500 mm. The anti-dispersion enclosure 3 is provided with a ventilation gap, and the length direction of the anti-dispersion enclosure 3 is consistent with the axis direction of the guide tube body 1. Prevent that the dispersion encloses fender 3 and comprises being provided with gapped and hollow plastics cover, the clearance is rectangular shape gap or round hole shape air outlet. As shown in fig. 2, when the gap is a circular hole-shaped air outlet, the circular hole-shaped air outlet extends from the inner wall of the enclosure to the outer wall in an inclined manner, and the inclined direction forms an included angle with the direction of the exit port of the guide tube. Alternatively, it may be formed of an array of bristles selected from plastic bristles or elastomeric filaments, as shown in fig. 3.

The utility model discloses can be applied to the seed field of scattering.
