Description

Technical Field

[0001] This application relates to the field of tobacco planting equipment technology, and more particularly to a tobacco fertilization device. Background Technology

[0002] Tobacco fertilization needs to be adjusted according to different growth stages and fertilization methods. It's not simply about spreading fertilizer evenly around the seedlings. Fertilization methods include: Base fertilizer: mainly farmyard manure and compound fertilizer, applied according to soil conditions to avoid single-nutrient application. Topdressing: applied in several stages. The first topdressing is applied 10-15 days after transplanting, combined with weeding and cultivation, and the second topdressing is completed before the seedling stage. Integrated water and fertilizer management: precise irrigation and fertilization through pipes improves fertilizer utilization. Fertilizer placement: fertilizer should be about 15 cm away from the rootstock of the tobacco plant to avoid direct contact with the roots and prevent root burn or disease. Fertilization time: adjusted according to soil and climate conditions, avoiding fertilization during high-temperature periods. Dosage control: avoid over-fertilization; apply small amounts frequently to ensure balanced nutrient distribution. Furthermore, the mulch should be broken when the tobacco seedling leaves are about to touch the ground, and the seedlings should be ready for transplanting 10-15 days after transplanting.

[0003] In related technologies, fertilization is usually done by spraying directly with a nozzle. However, during the spraying process, water and fertilizer may be sprayed onto the roots of the tobacco plants, which can cause seedling burn.

[0004] Film breaking devices typically use manual breaking or a ring heating ring to scald the film. Manual breaking requires the planter to bend over, which is labor-intensive, while the ring heating ring can easily come into contact with the tobacco seedlings during breaking, scalding and killing them.

[0035] To address the aforementioned problems, this application provides a tobacco fertilization device that sprays water and fertilizer around the tobacco plant at a certain distance, effectively protecting the tobacco and preventing the roots and stems from being burned by the water and fertilizer. Furthermore, the device effectively protects the tobacco seedlings during the film-breaking process, preventing them from being scalded.

[0036] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0037] Figure 1 This is a schematic diagram of the structure of a tobacco fertilization device shown in an embodiment of this application.

[0038] See Figure 1 Example 1 shows a tobacco fertilization device including a handheld spray nozzle 1, a connecting structure 2, a support device 3, a drive device 4, a base plate 5, a protective plate 6, a trumpet-shaped spraying plate 7, and a film-breaking device 8. The protective plate 6 forms a spraying space 12 by setting the base plate 5 and the detachable trumpet-shaped spraying plate 7. The spraying space 12 extends outward in a trumpet shape. A row of nozzles 10 is arranged on the base plate 5 at the top of the spraying space 12, surrounding the outside of the protective plate 6. Water and fertilizer are sprayed from the spraying space 12 through the nozzles 10. The protective plate 6 protects the seedlings, which can prevent water and fertilizer from directly contacting the tobacco roots and stems, thereby avoiding burning the seedlings.

[0039] The protective plate 6 is arranged in an arc shape to form a seedling protection space 11. The seedling protection space 11 and the spraying space 12 are provided with a seedling protection channel 9 that extends through the spraying space 12 into the seedling protection space 11. When spraying water and fertilizer, the tobacco leaves fall from the seedling protection channel 9 into the seedling protection space 11 by moving the protective plate 6, thereby protecting the seedlings and directly isolating the water and fertilizer from contacting the tobacco roots and stems.

[0040] The upper end of the guard plate 6 is slidably mounted on the support device 3 and is driven to reciprocate by the drive device 4. The support device 3 is mounted on the handheld spray pipe 1 in an adjustable direction through the connecting structure 2. The handheld spray pipe 1 is connected to the nozzle 10 through the hose 13. The drive device 4 drives the guard plate 6 to rotate, so that the water and fertilizer sprayed in the spraying space 12 can rotate to the soil below the seedling protection channel 9, thereby ensuring that water and fertilizer are sprayed around the tobacco and preventing water and fertilizer leakage below the seedling protection channel 9 when it is not rotated.

[0041] The handheld nozzle 1 is equipped with a handle switch 14, and the handle switch 14 is equipped with a first start switch 15 and a second start switch 16 that can be opened synchronously with the handle switch 14. The handheld nozzle 1 is connected to the pressure water and fertilizer cylinder. The pressure water and fertilizer cylinder can be carried by manpower or carried by a small cart.

[0042] The drive unit 4 is connected to the power supply via a wire and is controlled by the first start switch 15; when the operator presses the handle switch 14, he / she also presses the first start switch 15 to control the guard plate 6 to rotate, so that water and fertilizer can be sprayed around the tobacco.

[0043] A detachable film-breaking device 8 is installed at the bottom of the trumpet-shaped spray plate 7. The film-breaking device 8 is connected to the power supply and is controlled to start by the second start switch 16 on the handle switch 14. When the operator presses the handle switch 14, he / she also presses the first start switch 15 and the second start switch 16 at the same time to control the protective plate 6 to rotate, so that the film-breaking device 8 can burn a hole, while the tobacco seedlings are covered by the seedling protection space 11, which can prevent the seedlings from being burned and dying.

[0044] The protective plate 6 is divided into a lower seedling protection plate 17 and an upper seedling protection plate 18. The upper end of the lower seedling protection plate 17 is provided with a base plate 5, and the lower end of the base plate 5 is provided with a spray nozzle 10 surrounding the lower seedling protection plate 17. The protective plate 6 is installed by a sliding plate 19 and a sliding groove 20 provided on the trumpet-shaped spray plate 7 to form a seedling protection channel 9. The upper end of the trumpet-shaped spray plate 7 is fixed to the base plate 5 with screws, so that the trumpet-shaped spray plate 7 is detachable and easy to replace.

[0045] The protective plate 6 can be replaced with trumpet-shaped spray plates 7 of different trumpet diameters to form spraying spaces 12 with different coverage areas; it can effectively replace trumpet-shaped spray plates 7 of different sizes, thereby adjusting the coverage area of ​​the spraying space 12, and thus effectively adjusting the water and fertilizer spraying range.

[0046] Both sides of the seedling protection channel 9 have funnel-shaped spray plates 7 with curved guide plates 21. The two curved guide plates 21 are curved outward in a V-shape, and the ends of the curved guide plates 21 are rounded and smooth. The curved guide plates 21 can effectively pour tobacco seedlings in and prevent the curved guide plates 21 from damaging the tobacco seedlings.

[0047] The membrane breaking device 8 includes a heat insulation plate 22 and a heating plate 23. The heat insulation plate 22 is provided with a slot 24, and the heat insulation plate 22 can be detachably installed at the bottom of the trumpet-shaped spray plate 7 through the slot 24. The heating plate 23 is provided at the lower end of the heat insulation plate 22. The heating plate 23 is connected to a power source and is controlled to start by a second start switch 16. The power source is a battery, which can be placed at the bottom of the pressure water fertilizer cylinder on a manual carrying vehicle or a small trolley.

[0048] The support device 3 includes an arc-shaped plate 25 and a support groove 26. An electric telescopic rod 27 is fixedly installed in the support groove 26. One end of a connecting rod 28 is hinged to the top of the electric telescopic rod 27, and the other end of the connecting rod 28 is hinged to a support plate 29 on the outer wall of the guard plate 6. The guard plate 6 is pushed to reciprocate by the extension and retraction of the electric telescopic rod 27.

[0049] The connecting structure 2 includes a ball joint structure 30, a hinge structure 31, and a connecting pipe 32. The support device 3 is connected to the hinge structure 31 via the ball joint structure 30, which can be locked with a nut. The hinge structure 31 is connected to the connecting pipe 32 and can be locked with a locking nut. The upper end of the connecting pipe 32 is detachably connected to the handheld spray pipe 1, and the lower end is connected to one end of the flexible hose 13. The other end of the flexible hose 13 is connected to the nozzle 10. The ball joint structure 30 and the hinge structure 31 allow the support device 3 to be rotated to different positions, making it easier for the worker to cover the tobacco seedlings in the seedling protection space 11 when holding the handheld spray pipe 1.

[0050] After the trumpet-shaped spray plate 7 is inserted into the film-breaking device 8, its bottom is flush with the lower end of the protective plate 6. This ensures that when water and fertilizer are sprayed without the film-breaking device 8, after the protective plate 6 covers the tobacco, the protective plate 6 is pressed into the ground after the trumpet-shaped spray plate 7 contacts the ground. This ensures that when water and fertilizer are sprayed, the protective plate 6 covers the tobacco seedlings, and the tobacco roots and stems do not directly contact the water and fertilizer. After the film-breaking device 8 is installed, the protective plate 6 also contacts the film when the film-breaking device 8 contacts the film.

[0051] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
