Description

A nozzle for dust suppressant area seed spray-seeding operation

Technical Field

The utility model relates to the field of seed spray-seeding devices, in particular to a nozzle for dust suppressant spray-seeding operation with seeds.

Background

The seed spray-seeding is a common seed planting mode, but when the seeds are subjected to spray-seeding operation, the subsequent normal growth of the seeds can be directly influenced by the spray-seeding condition of a spray-seeding end. For example, in the case of not using a spray head, the seeds in the ejector can be sprayed outwards at a very high speed along with the liquid or gas, so that the seeds are sprayed outwards in a column form, and the spraying density and the spraying area of the seeds cannot be guaranteed at all; the common spray seeding liquid, such as dust suppressant, can play a role in suppressing dust when sprayed along with seeds. When the conventional nozzle structures such as a high-pressure nozzle or a spiral nozzle are used for spraying and sowing seeds, the high-pressure nozzle and the spiral nozzle have certain requirements on the passing rate of the seeds, so that the seeds are easy to block in the nozzle; when high-pressure spray sowing is carried out, some seeds can collide with the inner wall of the spray head with great impact force, so that the outer skin of the seeds is damaged, and the normal growth of the sprayed seeds is influenced; when carrying out seed spray-seeding operation in addition, because the seed spray-seeding has the requirement to the density of spray-seeding, and use traditional shower nozzles such as high-pressure nozzle to carry out the seed spray-seeding, can not ensure the seed outwards to carry out the diffusion spray-seeding with the overlay type spray-seeding mode, and then also can not ensure the spray-seeding efficiency when spouting the seeding.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a nozzle for dust suppressant spraying operation with seeds, which can ensure that the seeds are sprayed outwards at a sufficient spraying speed under the condition of ensuring that the seeds normally pass through the nozzle, ensure the spraying density and the spraying range of the seeds, and cannot damage the seeds in the process that the seeds enter the nozzle and are sprayed out of the nozzle, thereby ensuring the normal and effective spraying of the seeds.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

a nozzle for the seed spraying operation of a dust suppressant is characterized in that the spraying end of the nozzle is a slotted spraying opening, and the slotted spraying opening is communicated with the connecting end of the nozzle through a smooth curve shell.

Detailed Description

The utility model will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

The utility model relates to a nozzle 1 for seed spraying operation of a dust suppressant, wherein the spraying end of the nozzle 1 is a slotted spray opening 2 or a spot-seam spray opening, and the slotted spray opening 2 or the spot-seam spray opening is communicated with a connecting end 4 of the nozzle 1 through a smooth curve shell 3. The nozzle 1 is designed in consideration of the seed spraying speed, the seed spraying density, the seed spraying range, the seed passing performance and the seed spraying effect. However, in order to achieve the following advantageous effects, it is preferable that the length of the slit nozzle 2 is greater than the diameter of the connection end 4 of the nozzle 1. And the smooth curve shell 3 is mainly embodied that the inner surface of the nozzle 1 is a smooth curve, so that the following beneficial effects are better realized.

Seed spray-seeding speed:

when the spraying task of the seeds is carried out, the speed of the seeds sprayed outwards at the nozzle 1 needs to be guaranteed, and the seeds can be effectively sprayed only if the speed has a spraying condition. And traditional nozzle 1 structure is when installing, no matter is high pressure nozzle or spiral nozzle, all needs to install other supercharging devices, just can ensure the speed that the seed outwards sprayed in nozzle 1 department. And use the injection end to be the strip seam sprinkler orifice 2, and the strip seam nozzle orifice is through the nozzle 1 that smooth curve casing 3 is linked together with the link 4 of nozzle 1, it is similar to the nozzle structure in the ejector inside and is in the inside shower nozzle bore of ejector is less than the bore of injection end, and then after high-pressure rivers got into the shower nozzle from the injection end of shower nozzle, along with the diameter of shower nozzle constantly reduces, and then realize the pressure of water constantly increasing, and convert into velocity energy at the shower nozzle blowout, kinetic energy converts pressure energy into velocity energy promptly, and then spray from the injection end outwards, make the seed that sprays outwards from 1 strip seam sprinkler orifice 2 of nozzle, possess sufficient velocity energy, in order to ensure that the seed can reach appointed spray position.

Seed spray seeding density:

because use traditional nozzle 1 to carry out the seed and spray or directly when carrying out the seed and spray, under the effect that does not have the external force, the seed is for the outside route of spraying of column type spray-seeding is similar to the rivers of tap outside circulation from spraying the section for the seed is spraying when broadcasting, can only spray-seeding a position, and inconvenient staff operates. And when using the nozzle 1 that the injection end was the drilling sprinkler orifice 2 to carry out the seed task of spouting, the seed can be followed drilling sprinkler orifice 2 and outwards spouted with the sector, and then make the seed mode of spouting no longer be original column type mode of spouting, but outwards spout with the sector, and then satisfied the density of spouting of seed, no longer appear because the staff removes the device of spouting untimely as traditional mode of spouting, and lead to a position of spouting to appear a large amount of seeds accumulational problem.

The spray seeding range of the seeds:

compared with the seed spray-seeding density, the traditional seed column spray-seeding mode can not realize the effect of seed diffusion spray-seeding when the seed is sprayed. And when using above-mentioned nozzle 1 to spout and broadcast, the strip seam of nozzle 1 is spouted mouthful 2 and can be sprayed the seed with the sector outwards for the seed can realize the work of spraying of area on a large scale, and then when the early guarantee efficiency of spouting, can make the reasonable cover of seed spout and broadcast to the assigned position.

Seed trafficability:

here, the seed passability is to ensure that the seeds can be effectively sprayed out from the nozzle 1, so as to avoid the occurrence of blockage. When the traditional nozzle 1 structure is used for spray-seeding operation, the internal structure is complex, so that seeds can not pass through the nozzle 1 well, for example, the spiral nozzle is easy to block in a spiral channel of the spiral nozzle when the seeds pass through the spiral nozzle. And the strip seam nozzle 2 can play the pressurized effect, namely after getting into nozzle 1 inside, nozzle 1 narrows gradually for pressure increases gradually, and at the strip seam nozzle 2 department of nozzle 1, the pressure energy that the mixture has can turn into speed ability, outwards sprays out from strip seam nozzle 2, makes the inside jam problem that can not appear of nozzle 1.

The seed spraying effect is as follows:

the spraying effect of the seeds is the most important purpose of arranging such a nozzle 1, because the spraying of the seeds is performed in order to enable the seeds to grow, and the beneficial effects are not necessary if the physiological properties of the seeds are damaged and the normal growth of the seeds is affected during the spraying process. And the 1 seam injection end of nozzle in this device is linked together through smooth curve casing 3 and the link 4 of nozzle 1, uses smooth curve casing 3 to carry out the connection at nozzle 1 both ends, and when the mixture entered into nozzle 1 inside from link 4, the seed can not directly bump with the casing of nozzle 1, but slides through smooth curve casing 3 and converges to seam sprinkling outlet 2 department to spout outward at seam sprinkling outlet 2. Compared with the traditional nozzle 1 structure, such as a high-pressure nozzle, the passing performance is poor, and the high-pressure nozzle is not provided with a buffering shell like the smooth curve shell 3, so that seeds can directly collide with the inner wall of the high-pressure nozzle, the shell of the seeds is damaged due to collision, and the subsequent normal growth of the seeds is not easy to occur.

To achieve the above-mentioned advantageous effects, such a nozzle 1 is further optimized again:

a plurality of said slit spray openings 2 are at the spraying end of the nozzle 1, where the slit spray openings 2 are optimized. Because the seed spray-seeding in some places has certain requirement to the spray-seeding scope, therefore the strip seam sprinkling port 2 here does not stipulate its concrete shape when setting up, can realize the seed mode of strip seam spray-seeding promptly can, and will many strip seam sprinkling port 2 can further accelerate seed spraying rate and spray area at the injection end of nozzle 1, but should pay attention to the inconvenient shaping of carrying out when preparing of the injection end of nozzle 1 of many strip seam sprinkling ports 2, nevertheless do not get rid of its ability that can realize above-mentioned beneficial effect.

The inner wall of the nozzle 1 is covered with a protective member. The purpose of the protective element provided here is to further protect the seeds from rubbing against the inner wall of the nozzle 1, which could lead to damage to the seed enclosure. The protective member here may be a soft protective member such as a soft protective pad, but it is needless to say that the inner wall of the nozzle 1 may be directly subjected to a smooth polishing operation.

Therefore, the nozzle 1 for the dust suppressant spraying operation with seeds can ensure that the seeds are sprayed outwards at a sufficient spraying speed under the condition of ensuring that the seeds normally pass through the nozzle 1, ensure the spraying density and the spraying range of the seeds, and cannot damage the seeds in the process that the seeds enter the nozzle 1 and are sprayed out of the nozzle 1, thereby ensuring the normal and effective spraying of the seeds.
