Description

Backpack field disc seedling seeding machine

technical field

The utility model relates to a backpack type seedling spraying machine for raising field seedlings, and belongs to the technical field of backpack seeding machinery.

Background technique

Sowing is an extremely important part of agricultural production. "Half of the good harvest" is a summary of the importance of sowing that people have drawn from production practice for a long time. In modern precision agriculture, the requirements for the performance and quality of the seeder are getting higher and higher, and the sowing uniformity is an important indicator for evaluating the performance and quality of the seeder. In the process of seedling seedling spraying in the field, the uniformity of spraying is also an extremely important indicator. Good uniformity of spraying can fully improve the reasonable allocation of seed light, water, fertilizer, and air, so that seedlings in a single tray can emerge uniformly. The plants are thick and strong, ensuring high-quality planting results.

Traditional tray seedling sowing mostly uses industrialized sowing lines. Subsoil laying, seeding, and topsoil laying are completed in the factory at one time, and then the seedling tray is transported to the field for seedling growth. However, the slight vibration of the seedling tray due to human operation and multiple factors in the field during the transportation process may affect the quality of the seeds. Sowing uniformity or directly overturning the seedling tray to waste seeds.

The existing spraying machine is to spray the seeds in the form of fans and air ducts, which is suitable for sowing in wide areas, such as grasslands and green slopes on both sides of the street, and is also used for spraying of live rice and green grass seeds. Sowing can effectively control the amount of sowing, but when it is directly grafted to the field seedling raising equipment, the sprayed seeds will splash around, and the rice seeds cannot effectively fall into the seedling tray, resulting in a lot of waste of seeds, poor sowing uniformity, and unsatisfactory seedling raising effect .

Utility model content

The technical problem to be solved by the utility model is: for the sowing of seedlings in the field trays, the existing industrialized sowing line sowing method is cumbersome, and a slight vibration of the seedling trays may affect the sowing uniformity of the seeds or directly sow the seedlings. The tray is tilted and the seeds are wasted; while the existing spraying machine, the sprayed seeds will splash around, the rice seeds cannot effectively fall into the seedling tray, the seeds are wasted a lot, the sowing uniformity is not good, and the seedling raising effect is not ideal.

The utility model takes the following technical solutions:

A kind of knapsack-type field disc seedling seeding sprayer, comprising a knapsack support 7, the upper part of the knapsack support 7 is provided with a seed box 1, and the lower part of the seed box 1 is connected with the seeding mechanism 2, and the seeding mechanism 2 is controlled by frequency conversion DC The motor 4 is driven; the lower part of the seed-discharging mechanism 2 communicates with the seed-dropping pipe 5, and the lower part of the seed-dropping pipe 5 communicates with the middle part of the spray tube 8, and the starting end of the spray tube 8 is provided with a DC speed-regulating fan 3, The middle connecting section is a hose structure, which is easy to hold and change the direction of spraying; the battery 6 supplies power to the variable frequency DC motor 4 and the DC speed regulating fan 3; adjusts the speed of the variable frequency DC motor 4, and then adjusts the amount of seeds and Seeding speed; adjust the speed of the DC speed-regulating fan 3, and then adjust the spraying distance and spraying speed.

The characteristics of this technical solution are: a seed discharge mechanism 2 is provided, and the discharged seeds fall into the middle part of the spray cylinder 8 through the seed drop pipe 5, and the seed discharge amount and the discharge speed are adjusted by adjusting the rotating speed of the variable frequency DC motor 4, The DC speed-regulating fan 3 is located at the beginning of the spray tube 8 to provide wind power for the spray tube to spray the seeds falling in the spray tube 8. By adjusting the speed of the DC speed-regulating fan 3, the spraying distance and spraying speed can also be adjusted. .

Further, the storage battery 6 is arranged at the bottom of the backpack support 7 .

Further, the front half of the spray tube 8 is rigidly fixed on the back of the backpack support 7 .

Further, the piggyback support 7 has a rectangular structure as a whole.

The beneficial effects of the utility model are:

1) It can effectively adjust the seeding speed, spraying speed and spraying distance, and is especially suitable for seedling seeding in the field with high requirements on the sowing position.

2) The structure is simple, the operation is simple, the use is convenient, and the portability is convenient. It can realize uniform and efficient spraying and effective cultivation of seedlings directly in the field.

3) The spraying position is accurate and the density is uniform.

4) The seed is saved, and the seedling raising effect is good.

5) High work efficiency.

Detailed ways

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

Referring to Figure 1-3, the piggyback field disc seedling sprayer consists of a seed box 1, a seeding mechanism 2, a DC speed regulating fan 3, a frequency conversion DC motor 4, a seed drop tube 5, a battery 6, a backpack bracket 7 and a spray tube 8 and so on. The seed-discharging mechanism 2 is hooked below the seed box 1, and the seeds in the seed-box 1 are discharged into the seed-dropping pipe 5 by the seed-discharging mechanism 2. After mixing with the airflow blown out by the blower fan 3, the way spray tube 8 concentrates on spraying and sowing.

The air outlet of the speed-regulating fan 3 is connected with the spray tube 8 to control the blowing air volume in the spray tube; the frequency conversion DC motor 4 drives the seed meter shaft to achieve the purpose of controlling the sowing volume. When sowing, load the seeds to be sprayed in the seed box 1 (paddy rice, wheat, grass seeds, granular fertilizers, etc. can be applied), start the spraying machine, and control the spraying amount of the seeds with the frequency conversion DC 4 motor. The crop uses the governor to adjust the delivery air volume of the DC speed-regulating blower fan 3 . The operator needs to try spraying first to master the spraying amount at walking speed, and then stand in the gap of the neatly placed seedling raising trays to spray the seeds evenly into the seedling raising trays that need to be sown.

Working principle: This utility model adopts the principle of pneumatic conveying to mix the seeds discharged from the seed meter with the air flow and spray them out through the spray tube at high speed. The spray tube 8 is held by the operator to reciprocate and swing, and the throat mechanism is set at the appropriate position of the spray tube 8. Unicom seeding mechanism 2, the negative pressure formed in the throat will discharge the seeds from the metering device into the spray tube 8, the seeds will be sprayed out under the acceleration of the spray tube airflow, and finally scattered in the seedling tray laid in advance in the field to complete the sowing. This method has the advantages of high work efficiency, saving seeds, simple structure, simple operation and the like.

The backpack-type field disc seedling seeding machine is easy to operate, and it can realize uniform and efficient spraying and effective cultivation of seedlings directly in the field. And the sowing rate and wind speed can be adjusted according to different spraying seeds to achieve the purpose of effective sowing.

The utility model solves the problems of difficulty in handling after sowing in industrialized seedling raising and sowing lines, and easily destroys the uniformity of seeds; at the same time, it solves the problems that the existing jet seeding machine is driven by a diesel engine with a strong wind, the sowing rate cannot be adjusted, and the sowing uniformity is poor.
