Description

Technical Field

[0001] The utility model relates to the technical field of seed cultivation devices, in particular to a seed cultivation coating auxiliary device. Background Art

[0002] Seed coating is a technology that mixes seeds with pesticides in proportion so that the pesticides cover the surface of the seeds. It can improve the germination rate, uniformity of emergence, enhance resistance to diseases and pests, etc., and is of great significance to the yield and quality of crops.

[0003] However, the solubility of coating agent ingredients varies and they are prone to precipitation. Traditional devices do not have effective stirring or circulation systems to deal with this. After precipitation, the concentration of the agent is uneven, resulting in large differences in seed coating thickness and agent content, affecting seed quality and growth, such as different resistance to diseases and pests, and affected germination rates. Traditional seed mixers do not take into account the fragility of seeds, and the stirring method is strong, such as high-speed rotation of blades or direct contact of robotic arms, which cause collisions, friction, and squeezing of seeds. Improper stirring causes damage to the seed epidermis and internal structure, reduces the germination rate, weakens the growth of seedlings, makes them susceptible to disease, and affects the yield and quality of crops.

[0013] Furthermore, a sealing cover is provided at the seed inlet.

[0014] (3) Technical effects

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. A rationally designed spray pipe extends deep into the horizontal mixing tank and is rotatably connected to the tank wall. Several spray holes are provided along the length of the bottom, ensuring a more even coverage of the seed surface with the chemical, significantly improving the uniformity of seed coating. Multiple lifting plates are fixed to the lower half of the inner wall of the horizontal mixing tank. As the tank rotates, these plates continuously flip and lift the seeds, ensuring they are fully exposed to the sprayed chemical. This further ensures that each seed receives the chemical evenly, preventing some seeds from receiving too much or too little chemical.

[0017] 2. A stirring mechanism is provided inside the medicine storage tank, including a rotating shaft and spiral blades driven by motor 2, which can continuously stir the medicine to prevent the precipitation of the medicine components, ensuring that the medicine is always in a uniformly mixed state when it is transported to the spraying pipe, so that the concentration of the sprayed medicine is consistent, effectively solving the problem of uneven coating caused by medicine precipitation and improving the stability of seed coating quality.

[0018] 3. This device uses an indirect method to coat the seeds, that is, the seeds are turned over by the rotation of the horizontal mixing tank and the action of the lifting plate, instead of directly stirring the seeds with a traditional mixer. This avoids the seeds from being damaged by collision, friction and squeezing due to direct contact with strong stirring components, and protects the integrity and germination ability of the seeds to the greatest extent, which is conducive to improving the germination rate of seeds and the healthy growth of seedlings, laying a good foundation for a good harvest of crops.

[0029] Combined with attachment Figure 1 To the attached Figure 6, a seed cultivation coating auxiliary device, comprising a medicine storage tank 1, a base frame 2 and a horizontal stirring tank 3 rotatably arranged inside the base frame 2, wherein a stirring mechanism is provided inside the medicine storage tank 1, a medicine adding port 13 is provided at the upper end of the medicine storage tank 1, a waste outlet 14 is provided at the bottom of the medicine storage tank 1, a seed inlet 4 is provided at the upper end of the horizontal stirring tank 3, a sealing cover (not shown in the figure) is provided at the seed inlet 4, a plurality of lifting plates 5 are fixedly provided on the lower half of the inner wall of the horizontal stirring tank 3, a motor 6 for driving the horizontal stirring tank 3 to rotate is fixedly provided on the side of the base frame 2, a liquid pump 8 is connected to the side of the medicine storage tank 1, and a liquid outlet pipe of the liquid pump 8 is connected to a spraying pipe 7 through a pipe 9, and the spraying pipe 7 penetrates into the interior of the horizontal stirring tank 3 and is rotatably connected to the left and right side walls of the horizontal stirring tank 3.

[0030] In this embodiment, as a preferred technical solution, the stirring mechanism includes a motor 2 10 fixedly mounted on the upper end of the medicine storage tank 1, a driving shaft of the motor 2 10 extending into one end of the medicine storage tank 1 is fixedly provided with a rotating shaft 11, and a spiral blade 12 is fixed on the rotating shaft 11.

[0031] In this embodiment, as a preferred technical solution, a plurality of spray holes 15 are provided at the bottom of the spray pipe 7 along its length direction. The spraying direction of the spray holes 15 is vertically downward and fixed. A semicircular arc protective cover 16 is fixed at the upper end of the spray pipe 7.

[0032] The operating principle of the seed cultivation and coating auxiliary device of the present invention is as follows: the stirring mechanism in the medicine storage tank 1 is activated, and the motor 10 drives the rotating shaft 11 to rotate, which in turn drives the spiral blade 12 to rotate. During the rotation, the spiral blade 12 stirs the medicine in the medicine storage tank 1, ensuring thorough mixing and preventing precipitation. This ensures that the medicine is uniform in composition and concentration when it is delivered to the horizontal mixing tank 3. The motor 6 drives the horizontal mixing tank 3 to rotate within the base frame 2. When seeds enter the horizontal mixing tank 3 through the seed inlet 4, the lifting plate 5 continuously stirs and lifts the seeds as the mixing tank rotates. Simultaneously, the liquid pump 8 draws the medicine from the medicine storage tank 1 and delivers it to the spraying pipe 7 through the pipe 9. The spraying pipe 7 extends deep into the horizontal mixing tank 3. Its bottom is provided with a plurality of spray holes 15 along its length. The medicine is sprayed vertically downward from the spray holes 15, evenly spraying the seeds stirred by the lifting plate 5, thus coating the seeds.

[0033] The working process of the seed cultivation coating auxiliary device of the utility model is as follows:

[0034] 1. Preparation: Check whether all parts of the equipment are in good condition, such as whether the medicine storage tank 1, horizontal mixing tank 3, motor 6, liquid pump 8, etc. are operating normally, whether the pipeline connections are tight, add an appropriate amount of seed coating agent into the medicine storage tank 1 from the dosing port 13, open the sealing cover at the seed inlet 4, and prepare to put the seeds.

[0035] 2. Start the stirring mechanism: Turn on the second motor 10 to drive the rotating shaft 11 and the spiral blade 12 to rotate, stirring the medicine in the medicine storage tank 1 to prevent the medicine from settling and maintain the uniformity of the medicine.

[0036] 3. Adding seeds and starting the mixing tank: The seeds to be coated are placed into the horizontal mixing tank 3 through the seed inlet 4. The sealing cover is then closed and the motor 6 is started to drive the horizontal mixing tank 3 to slowly rotate within the base frame 2. At this time, the lifting plate 5 begins to turn the seeds as the mixing tank rotates, keeping the seeds in a state of constant movement.

[0037] 4. Spraying the medicine: Turn on the liquid pump 8, which extracts the evenly stirred medicine in the medicine storage tank 1 and transports it to the spraying pipe 7 through the pipe 9. The medicine is sprayed vertically downward from the spraying hole 15 at the bottom of the spraying pipe 7 and evenly sprinkled on the seeds turned by the lifting plate 5, achieving full contact between the medicine and the seeds and the coating process.

[0038] 5. Completion of coating and subsequent processing: After a period of stirring and spraying, when the seeds reach the expected coating effect, turn off the motor 6, motor 2 10 and liquid pump 8. Open the sealing cover at the seed inlet 4 of the horizontal mixing tank 3, rotate the horizontal mixing tank 3 so that the seed inlet 4 is facing downward, pour the seeds from the seed inlet 4, collect the coated seeds, and carry out subsequent processing or storage. If the agent in the medicine storage tank 1 needs to be replaced or cleaned, the remaining agent can be discharged through the waste outlet 14 and cleaned. At the same time, in order to prevent the seeds from clogging the spray hole during the spraying process, a semicircular arc protective cover 16 is fixed on the upper end of the spray pipe 7. It should be noted that the amount of seeds put in cannot exceed the height of the spray hole.

[0039] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
