A fertilizing device for kale cultivation

Abstract

This invention discloses a fertilization device for kale cultivation, relating to the field of fertilization devices. It solves the problem that existing fertilization devices for kale cultivation easily disperse fertilizer particles and dust into the air during the scattering and burying process, causing these particles to fall onto the kale leaves and affect plant growth and leaf quality. The device includes a main body, a shovel, a dust removal mechanism, and an auxiliary mechanism. The dust removal mechanism includes a screen, a conveyor belt, and a dripping pipe. This invention uses the dust removal mechanism to pre-screen the granular fertilizer through the screen, causing the dust to fall onto the conveyor belt and accumulate. The dripping pipe drips mud beads from the upper area of ​​the conveyor belt, which absorb dust along the way and are finally discharged along with the granular fertilizer, completing the fertilization operation. This prevents powdery fertilizer from being dispersed into the air and falling onto the kale leaves during the output process. The auxiliary mechanism covers the soil after fertilization and then irrigates the kale.

Description

Technical Field

[0001] This invention relates to the field of fertilization device technology, specifically a fertilization device for kale cultivation. Background Technology

[0002] Kale, a leafy vegetable with high nutritional value, possesses both edible and ornamental value. Its cultivation process requires strict adherence to fertilizer application standards. Granular compound fertilizers and slow-release fertilizers are commonly used in kale field cultivation, providing nitrogen, phosphorus, potassium, and trace elements to continuously support plant growth, ensuring tender leaves and robust growth. Currently, granular fertilizer application devices for leafy vegetables are primarily of the spreading and burying type. These devices use mechanical transmission structures to dispensing, spreading, or directly burying fertilizer into the soil, improving the efficiency of kale field fertilization to some extent, reducing manual labor intensity, and meeting the needs of large-scale cultivation.

[0003] Due to the production process and transportation, commercially available granular fertilizers generally contain a certain amount of fine powder. During the spreading or landfilling process, the mechanical operation of the equipment and the collision and friction between fertilizer granules further exacerbate the dust dispersion, causing a large amount of fine fertilizer powder to float in the air and eventually settle and adhere to the surface of kale leaves. The core of kale's edible and commercial value lies in its leaves, which are tender and have a thin epidermis, making them extremely intolerant of external adhering substances. Fertilizer powder adhering to leaves for extended periods can have multiple adverse effects: First, the high concentration of inorganic salts in fertilizer powder dissolves rapidly upon contact with dew or humidity, forming a hypertonic solution on the leaf surface. This disrupts the osmotic pressure balance of the leaf epidermal cells, leading to cell dehydration, cell wall damage, and symptoms such as brown scorched spots, curled and shrunken leaf edges. In severe cases, localized necrosis of leaf tissue can occur, forming lesion-like defects. Second, powder buildup can clog leaf stomata, hindering normal photosynthesis and respiration, affecting chlorophyll synthesis, causing leaves to yellow and become brittle, reducing their freshness and luster. Third, the adhering fertilizer powder is difficult to remove completely with simple washing, affecting not only the appearance and marketability of kale but also causing a bitter and astringent taste, significantly reducing its edible quality. Furthermore, powder residue increases the risk of pests and diseases, further impacting the plant's normal growth. Summary of the Invention

[0004] The purpose of this invention is to provide a fertilization device for kale cultivation that facilitates improved fertilization efficiency while preventing fertilizer powder from drifting onto the plant leaves, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fertilization device for kale cultivation, comprising a body, a dust removal mechanism, and an auxiliary mechanism. Multiple sets of shovels are fixedly connected to the bottom of the body. The dust removal mechanism includes a screen installed inside the body. A conveyor belt is provided inside the body, inclined below the screen. Multiple sets of dripping pipes are provided on the upper side of the conveyor belt.

Mud droplets drip from the upper area of ​​the conveyor belt and absorb dust along the way during the flow. Finally, they are discharged together with the granular fertilizer to complete the fertilization operation.

Rollers 40 are rotatably connected to both sides of the body 1. The dust removal mechanism includes a screen 3 installed inside the body 1. A conveyor belt 4 is installed inside the body 1, angled below the screen 3. Multiple sets of drip pipes 5 are located on the upper side of the conveyor belt 4. The dust removal mechanism can dissolve granular fertilizer... The dust is initially sieved through screen 3, causing it to fall onto conveyor belt 4 and accumulate. Dust droplets drip from the upper area of ​​conveyor belt 4 through drip pipe 5, absorbing dust along the way. Finally, the dust is discharged along with the granular fertilizer, completing the fertilization process. This avoids wetting the entire fertilizer while ensuring the internal powder is utilized and clumps together, preventing powdered fertilizer from scattering into the air and landing on the kale leaves during output. An auxiliary mechanism is installed at the bottom of the machine body 1, away from the shovel plate 2, to cover the soil after fertilization. For irrigation, the dust removal mechanism also includes a first rotating shaft 6 fixedly installed at the end of the screen 3 away from the conveyor belt 4.

The soil is turned over by the shovel plate 2 at the front end and the granular fertilizer after screening is continuously output from the rear. At the same time, the powdered fertilizer is separated and agglomerated inside the machine body 1 and discharged together with the granular fertilizer into the turned soil trough. During the movement of the machine body 1, the auxiliary mechanism at the rear fills the turned soil pile on top of the fertilizer and waters it to complete the fertilization operation.

The inner wall of the conveyor belt 4 is connected to the outer wall of the two sets of drive shafts 13. The vibrating component includes a first motor 14 fixedly installed inside the machine body 1. The preferred model of the first motor 14 is Y. The YHS-40 has a first motor 14 whose output end is coaxially and fixedly connected to one end of an upper drive shaft 13. A first gear 15 is coaxially and fixedly connected to the end of the upper drive shaft 13 furthest from the first motor 14. A lever 16 is rotatably connected inside the machine body 1. One end of the lever 16 is coaxially and fixedly connected to a second gear 17 that meshes with the first gear 15. The pitch circle radius of the first gear 15 is larger than that of the second gear 17, allowing the second gear to drive the lever 16 to rotate at a faster speed. Multiple sets of lever blocks 18 that can abut against the bottom of the screen 3 are uniformly and fixedly connected to the outer wall of the lever 16. The feed component includes an input frame 19 fixedly installed on the upper side of the machine body 1. Multiple sets of arc-shaped grooves 20 are uniformly opened inside the input frame 19. The inner wall of the arc-shaped grooves 20 rotates... A conveying screw 21 is dynamically connected, with adjacent sets of conveying screws 21 having opposite spiral directions. A rotating rod 22 is coaxially fixedly connected inside the conveying screw 21. The rotating rod 22 passes through one side of the input frame 19 and is rotatably connected to the input frame 19. A transmission gear 23 is coaxially fixedly connected to one end of the rotating rod 22. Adjacent transmission gears 23 mesh with each other for transmission. A second motor 24 is fixedly connected inside the machine body 1. The preferred model of the second motor 24 is YYHS-40. The output end of the second motor 24 is coaxially fixedly connected to any one of the transmission gears 23. A first slope block 38 is provided on the upper side of the input frame 19. A second slope block 39 is fixedly connected inside the machine body 1. The second slope block 39 is located above the toggle lever 16. The first slope block 38 and the second slope block 39 are connected in a series of steps. The inclined surfaces of 9 are all facing the second motor 24 and are inclined upwards. The conveying component includes a guide frame 25 fixedly installed inside the machine body 1. A sliding rod 26 is slidably connected in the horizontal direction inside the guide frame 25. A reciprocating screw 27 is rotatably connected inside the guide frame 25. The reciprocating screw 27 passes through the sliding rod 26 and is threadedly connected to the sliding rod 26. A third gear 28 is coaxially fixedly connected to one end of the actuating rod 16 away from the second gear 17.

The machine body 1 is provided with a driving component for inputting mud into the dripping pipe 5. The driving component includes a first water tank 30 fixedly installed inside the machine body 1. A conveying pipe 31 connected to one end of the dripping pipe 5 is opened in the sliding rod 26.A pumping pipe 32 is fixedly connected to the bottom of the sliding rod 26. The bottom end of the pumping pipe 32 is connected to the first water tank 30, and the top end of the pumping pipe 32 is connected to the conveying pipe 31. This device enables continuous automatic screening and output of granular fertilizer. Simultaneously, powdered fertilizer settles and clumps after screening, ultimately being output from the bottom along with the granular fertilizer into the soil trough, completing the fertilization operation. This effectively improves fertilization efficiency and avoids the problem of powdered fertilizer being blown onto the surrounding kale leaves during direct discharge, ensuring healthy plant growth and more aesthetically pleasing and healthy leaves.

[0031] Example 3: Please refer to Figures 1-5 This embodiment further illustrates Embodiment 1. The auxiliary mechanism shown in the figure includes a soil-covering plate 33 rotatably connected to the side of the machine body 1 away from the shovel plate 2. Multiple sets of elastic members 34 are fixedly connected to the upper side of the soil-covering plate 33 on the machine body 1. A second water tank 35 is fixedly connected inside the machine body 1 near the soil-covering plate 33. Multiple sets of drain pipes 36 are connected to the bottom side of the second water tank 35. The outlet of the drain pipes 36 is located above the soil-covering plate 33. Multiple... A set of atomizing nozzles 37 are connected to the second water tank 35 via a pumping device. A high-strength elastic element 34 pushes the bottom of the cover plate 33 to keep it in close contact with the soil, so that the soil pile turned up on the upper side can be pushed into the soil trench for filling. At the same time, the drainage pipe 36 irrigates from above the cover plate 33, which can help to wash the cover plate 33 and make the water flow more even. The elastic element 34 can be replaced by an existing retractable and rebound structure such as a spring.

[0032] Working principle: The machine body 1 moves along the fertilization route between the rows, pouring fertilizer from above into the input box 19. The fertilizer rolls down the first slope block 38 into the arc-shaped trough 20. The second motor 24 is started, driving multiple sets of transmission gears 23 to rotate synchronously. The transmission gears 23 drive the rotating rod 22, causing the conveying screw 21 to rotate, which in turn pushes the fertilizer inside the arc-shaped trough 20 to one side of the second slope block 39 at a uniform speed. This device makes the conveying speed of the fertilizer more uniform and stable, and also allows the fertilizer to fall more dispersedly onto the upper side of the screen 3. After being output from one end of the arc-shaped trough 20, the fertilizer falls onto the upper side of the screen 3 after being guided by the second slope block 39, and then along the screen... The screen 3 tilts and rolls downwards to one end close to the first rotating shaft 6. Small particles of powder fall through the screen 3 into the lower area, while large particles of fertilizer continue to be conveyed downwards from the conveying trough 7 to the top of the output plate 11. The output plate 11 is designed to rotate around the second rotating shaft 10, so that the bottom of the output plate 11 can automatically sense the height of the soil pile and lift it. After the fertilizer is guided by multiple sets of guide troughs 12, it is output into the soil trough. The position of the shovel plate 2 corresponds to the position of the output port at the bottom of the guide trough 12, so that when the machine body 1 is traveling in a near straight line, the fertilizer can be accurately conveyed along the guide trough 12 into the soil trough shoveled by the shovel plate 2. Then, the soil covering plate 33 at the rear is used for soil covering and burying to prevent dust from scattering.

[0033] The first motor 14 is started, and the output of the reducer drives the drive shaft 13 to rotate slowly. The drive shaft 13 drives the conveyor belt 4 to convey downwards at a very slow speed. This ensures that the powder screened from the screen 3 falls stably onto the conveyor belt 4 after being settled by the atomizing nozzle 37. It also reduces the probability of fertilizer and mud accumulating on the upper side of the conveyor belt 4 to form a mud layer, which would affect subsequent use. The continuous downward conveying of the conveyor belt 4 pushes the mud layer adhering to the upper side towards the scraper 9 and scrapes it off onto the output plate 11 to mix with the granular fertilizer for output. The drive shaft 13 drives the first gear 15 to rotate, which in turn drives the second gear 17 and the actuating rod 16 to rotate. The actuating block 18 on the outer wall of the actuating rod 16 continuously hits the bottom of one end of the screen 3 from bottom to top, causing the screen 3 to vibrate and screen around the first rotating shaft 6, improving the screening efficiency and preventing the screen 3 mesh from being blocked. The actuating rod 16 drives the third gear 28 to drive the fourth gear 29 to rotate, and the fourth gear 29 drives the reciprocating wire. Rod 27 causes sliding rod 26 to slide horizontally back and forth along the inner wall of guide frame 25, thereby continuously switching the position of dripping pipe 5, so that the dripping position of multiple sets of dripping pipe 5 can continuously cover the entire upper surface of conveyor belt 4. The first water tank 30 is filled with continuously stirred mud with a certain viscosity. The dripping pipe 5 pumps the mud to the upper conveying pipe 31 through pumping pipe 32 and discharges it from the side dripping pipe 5. The dripping pipe 5 has a large diameter and is not easy to clog. The sticky mud that comes into contact with the conveyor belt 4 quickly adheres to the powder fertilizer on the surface and rolls downwards. It is output from the bottom to the output plate 11 and buried together with the granular fertilizer. The mud has a large viscosity. Even if it does not roll down, it will form multiple mud beads on the upper side of conveyor belt 4, adsorbing the surrounding powder fertilizer. Then, it is conveyed downwards by conveyor belt 4 to the position of scraper 9 and scraped off. The speed of mud dripping and the speed of conveyor belt 4 can be flexibly adjusted as needed to ensure that the powder fertilizer on conveyor belt 4 can be continuously and fully adsorbed and removed.

[0034] The second water tank 35 stores clean water and can spray extremely fine atomized water particles through the atomizing nozzle 37 to assist sedimentation and avoid completely wetting the conveyor belt 4. Water is continuously and uniformly output through the drain pipe 36, flowing down the upper side of the cover plate 33 to irrigate the covered soil. Alternatively, the spray volume of the atomizing nozzle 37 can be increased, the conveyor can be eliminated, and a cutting mechanism can be installed on the upper side of the slope panel 8 to cut the mud flakes before output. This also achieves the purpose of sedimentation and output of powdered fertilizer.
