Description

Technical Field

[0001] The present invention relates to the technical field of nursery stock cultivation, and particularly relates to a nursery stock cultivation device and a nursery stock cultivation method. Background Art

[0002] Nursery stock cultivation refers to the process of scientifically managing and cultivating plant seeds, branches or other propagation materials under specific environmental conditions through artificial intervention so that they grow into seedlings meeting specific specifications and quality requirements. This process is a basic link in fields such as forestry, horticulture, and ecological restoration, directly affecting the survival rate, growth rate and ecological adaptability of subsequent planting.

[0003] Generally, during the process of nursery stock cultivation, staff need to frequently spray water, fertilizers and water on the nursery stock. Since there are a large number of nursery stocks planted in the greenhouse, the spraying area is insufficient when spraying the nursery stock by machinery, thus affecting the growth and development of the nursery stock.

[0004] In summary, how to solve the problem that the insufficient spraying area affects the growth and development of nursery stock when spraying the nursery stock has become a technical problem that needs to be urgently solved by those skilled in the art. Therefore, it is necessary to propose a nursery stock cultivation device and a nursery stock cultivation method. Summary of the Invention

[0005] To solve the above problems, the present invention provides a nursery stock cultivation device and a nursery stock cultivation method. Through the cooperative action of the first connecting rod, the second connecting rod and the third connecting rod, the piston head is driven to slide in the piston cylinder, and the fertilizer and water are pressed into the spray head for spraying. Through the up and down swing of the swing ring, the spraying area of the spray head is increased, thereby ensuring the growth and development of the nursery stock.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A nursery stock cultivation device includes a slide rail device. The bottom of the slide rail device is fixedly connected with a box body. The box body is provided with a storage assembly for storing fertilizers and water, a stirring assembly for mixing fertilizers, a suction assembly for sucking the fertilizer mixture, a spraying assembly for spraying the nursery stock, a driving assembly for driving the operation of the suction assembly, and a swing assembly for driving the swing of the spraying assembly.

[0007] The driving assembly includes a fixed block and a controller. The fixed block is fixedly connected to the inner bottom wall of the box body. A driving member is fixedly connected to the fixed block. The controller is used to control the operation of the driving member. One end of the output shaft of the driving member is fixedly connected with a rotating rod. The end of the rotating rod away from the driving member is hinged with a first connecting rod. One end of the first connecting rod away from the rotating rod is hinged with a second connecting rod. One end of the second connecting rod away from the first connecting rod is hinged with a third connecting rod. The inner bottom wall of the box body is fixedly connected with a support block. The middle part of the second connecting rod is rotationally matched with the support block. One end of the third connecting rod away from the second connecting rod is hinged with the suction assembly.

[0008] The technical principle of the above solution is as follows: The box body is driven to move in the greenhouse through the slide rail device. The driving part drives the first connecting rod to swing, and then drives the third connecting rod to swing through the second connecting rod, thereby driving the suction component to move, sucking the water and fertilizer from the mixing component into the suction component and then squeezing it into the spraying component for spraying. Through the swing of the swing component, the spraying area of the spraying component is increased. Thus, the seedlings are sprayed all-round, promoting the growth and development of the seedlings.

[0009] The mixing component mixes and stirs the fertilizer and water, enabling the fertilizer and water to be evenly mixed into water and fertilizer, thereby improving the spraying efficiency of the spraying component.

[0010] The following are the beneficial effects of adopting the above solution:

[0011] 1. In the present invention, through the drive of the swing component, the spraying component can achieve swing spraying, expanding the spraying range, improving the uniformity of spraying, and contributing to the uniform growth of seedlings.

[0012] 2. In the present invention, through the design of the mixing component, the fertilizer and water can be fully mixed, improving the solubility and utilization rate of the fertilizer, reducing the waste of fertilizer. And the solenoid valve in the storage component can accurately control the feeding amount of the fertilizer, avoiding the damage to the seedlings caused by over-fertilization.

[0013] Furthermore, the mixing component includes a mixing tank, which is fixedly connected to the inner bottom wall of the box body. The output shaft of the driving part far from the rotating rod penetrates through the mixing tank and is fixedly connected with a mixing rod, and a plurality of mixing blades are circumferentially fixedly connected to the mixing rod.

[0014] Beneficial effect: When the driving part operates, the mixing rod and the mixing blades will rotate, fully stirring the fertilizer and water in the mixing tank, ensuring that the fertilizer is evenly dissolved in the water, improving the mixing efficiency. At the same time, the residue of the fertilizer in the mixing tank is reduced, avoiding the problems of fertilizer waste and uneven growth of seedlings caused by uneven mixing.

[0015] Furthermore, the storage component includes a storage tank, which is fixedly connected to the inner top wall of the box body. A partition plate is vertically fixedly connected in the storage tank, dividing the storage tank into a first chamber and a second chamber from left to right in sequence. Discharge ports are opened at the bottoms of the first chamber and the second chamber, and solenoid valves are fixedly communicated in the discharge ports. The controller is used to control the opening and closing of the solenoid valves. The discharge ports are all communicated with the mixing tank.

[0016] Beneficial effect: The storage tank is divided into a first chamber and a second chamber by the vertically fixed partition plate, and different types of fertilizers or water can be stored respectively, avoiding the mixing and pollution between different fertilizers, and facilitating classified management and use. By controlling the opening and closing and the opening degree of the solenoid valve, the discharge amount of each chamber can be accurately controlled to meet the requirements of different seedlings for fertilizers and water.

[0017] Further, a bearing plate is fixedly connected to the inner side wall of the box body. The swinging assembly includes a rotating disc and a swinging ring. The rotating disc is eccentrically and fixedly connected to the output shaft of the driving member, and the rotating disc is located between the driving member and the rotating rod.

[0018] The inner side wall of the swinging ring is in sliding fit with the side wall of the rotating disc. A swinging column is fixedly connected to the top of the swinging ring. A sliding groove for the swinging column to slide is formed on the bearing plate. The swinging column is located in the sliding groove and is in sliding fit with the sliding groove. The top of the swinging column is fixedly connected to the suction assembly.

[0019] Beneficial effects: The sliding groove formed on the bearing plate is in sliding fit with the swinging column, providing a clear movement track for the swinging column, enabling the swinging ring to swing along a predetermined path, and enhancing the stability of the swing.

[0020] Further, the suction assembly includes a piston cylinder. The piston cylinder is fixedly connected to the top of the swinging column. An inlet and an outlet are formed on the piston cylinder. One-way valves are fixedly connected to both the inlet and the outlet. The inlet is fixedly communicated with an inlet pipe, and one end of the inlet pipe away from the inlet is fixedly communicated with the mixing tank. The outlet is fixedly communicated with an outlet pipe, and one end of the outlet pipe away from the outlet is fixedly communicated with the spraying assembly.

[0021] A piston head is in sliding fit inside the piston cylinder. One end of the piston head away from the inlet is hinged to a push rod, and one end of the push rod away from the piston head is hinged to a third connecting rod.

[0022] Beneficial effects: One end of the piston head away from the inlet is hinged to the push rod, and one end of the push rod away from the piston head is hinged to the third connecting rod. This hinged manner makes the movement of the piston head more stable and reliable. Through the suction of the water and fertilizer by the inlet pipe and the delivery of the water and fertilizer by the outlet pipe, an efficient and stable spraying effect of the spraying assembly is achieved.

[0023] Further, the spraying assembly includes a plurality of spray heads. The spray heads are all fixedly connected to the bottom of the swinging ring. The bottoms of the spray heads all penetrate through the box body and extend to the outside of the box body. Cavities are formed in both the swinging ring and the swinging column, and adjacent cavities are communicated with each other. The spray heads are all communicated with the cavity inside the swinging ring, and the outlet pipe is fixedly communicated with the cavity inside the swinging column.

[0024] Beneficial effects: A plurality of spray heads are all fixedly connected to the bottom of the swinging ring. As the swinging ring swings, the spray heads can cover a wider area to achieve uniform spraying. This design ensures that the seedlings can evenly receive the nourishment of the fertilizer mixture during the growth process, improving the spraying effect.

[0025] Further, an anti-corrosion coating is fixedly connected to the inner wall of the mixing tank.

[0026] Beneficial effects: During the cultivation of seedlings, the mixing tank comes into contact with various fertilizers, water, and possible chemical additives, which may corrode the inner wall of the mixing tank. The anti-corrosion coating can effectively resist the erosion of these chemical substances, thereby extending the service life of the mixing tank.

[0027] Furthermore, a transparent window is fixedly connected to the box body.

[0028] Beneficial effects: Through the transparent window, the staff can directly observe the operation of each component inside the box. This helps the staff to promptly detect equipment abnormalities or failures and ensure the normal operation of the equipment.

[0029] Furthermore, filter nets are fixedly connected inside both the liquid inlet and the liquid outlet.

[0030] Beneficial effects: During the cultivation of seedlings, the fertilizers and water in the mixing tank may contain impurities such as particles and fibers. The filter nets inside the liquid inlet and the liquid outlet can effectively filter these impurities and prevent them from entering the spray head and causing blockages.

[0031] Furthermore, a method for cultivating seedlings includes the following steps:

[0032] Step 1, Seedling planting: Plant the seedlings to be cultivated in the greenhouse.

[0033] Step 2, Water and fertilizer preparation: Stir in the mixing component according to the fertilizers and water required by the seedlings to prepare a water and fertilizer mixture.

[0034] Step 3, Position adjustment: Drive the box body to move through the slide rail device to reach the seedlings where fertilization is required.

[0035] Step 4: Fertilization: Spray the water and fertilizer mixture onto the seedlings through the spray component for fertilization.

[0036] Beneficial effects: Customize the water and fertilizer formula according to the growth stage of the seedlings and soil conditions, avoid over-fertilization or nutrient deficiency, reduce fertilizer waste and environmental pollution. The mixing component ensures uniform dissolution of the fertilizer, prevents blockage of the spray component, improves fertilizer utilization rate, and promotes root absorption of the seedlings.

[0037] The slide rail device can quickly move the box body to the target seedlings, avoiding physical consumption and time waste of manual handling. The spray component ensures uniform coverage of the water and fertilizer mixture on the leaves and roots of the seedlings through swinging and multi-point spraying design, avoiding local nutrient surplus or deficiency.

[0038] The additional aspects and advantages of the present invention will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present invention. Description of the Drawings

Detailed Description of the Invention

[0044] The following is a further detailed description through specific embodiments:

[0045] Embodiment 1:

[0046] As shown in the Figures 1 - 3 accompanying drawings: A seedling cultivation device includes a slide rail device.

A driving member is bolt - fixedly connected to the fixed block 11. In this embodiment, the driving member is selected as a driving motor 13. The controller is used to control the operation of the driving motor 13. One end of the output shaft of the driving motor 13 is bolt - fixedly connected with a rotating rod 10.

The end of the third connecting rod 5 away from the second connecting rod 6 is hinged with the suction component.

[0048] Combination Figure 3 As shown, the stirring assembly includes a stirring box 21, which is bolted fixedly connected to the inner bottom wall of the box body 17, and the output shaft of the driving motor 13 at one end away from the rotating rod 10 passes through the stirring box 21 and is bolted fixedly connected to the stirring rod 1, and a plurality of stirring blades 2 are bolted fixedly connected to the stirring rod 1 circumferentially.

[0049] The storage assembly includes a storage box 18, which is bolted and fixedly connected to the top wall of the box body 17. A partition plate 19 is vertically bolted and fixedly connected in the storage box 18 to divide the storage box 18 into a first chamber and a second chamber from left to right. The first chamber and the second chamber are both provided with discharge ports at the bottom. The discharge ports are both screwed and connected to a solenoid valve 20. The controller is used to control the opening and closing of the solenoid valve 20. The discharge ports are all connected to the mixing box 21.

[0050] Combination Figure 1 As shown, a bearing plate 3 is fixedly connected to the inner wall of the box body 17 by bolts.

[0051] The swing assembly includes a rotating disk 12 and a swing ring 8. The rotating disk 12 is fixedly connected to the output shaft of the driving motor 13 by an eccentric bolt. The rotating disk 12 is located between the driving motor 13 and the rotating rod 10. The inner side wall of the swing ring 8 is slidably matched with the side wall of the rotating disk 12. The top of the swing ring 8 is bolted and fixedly connected with a swing column 14. The bearing plate 3 is provided with a slide groove for the swing column 14 to slide. The swing column 14 is located in the slide groove and slidably matched with the slide groove. The top of the swing column 14 is bolted and fixedly connected with the suction assembly.

[0052] Combination Figure 2 As shown, the suction assembly includes a piston cylinder 4, which is bolt-fixedly connected to the top of the swing column 14. The piston cylinder 4 is provided with a liquid inlet and a liquid outlet, and a one-way valve is screw-fixedly connected to the liquid inlet and the liquid outlet. The liquid inlet is screw-fixedly connected to a liquid inlet pipe, and the end of the liquid inlet pipe away from the liquid inlet is screw-fixedly connected to the stirring box 21. The liquid outlet is screw-fixedly connected to a liquid outlet pipe, and the end of the liquid outlet pipe away from the liquid outlet is screw-fixedly connected to the spray assembly. A piston head 16 is slidably fitted in the piston cylinder 4, and a push rod 15 is hingedly connected to the end of the piston head 16 away from the liquid inlet, and the end of the push rod 15 away from the piston head 16 is hingedly connected to the third connecting rod 5.

[0053] The spray assembly includes a plurality of spray heads, which are all screwed and fixedly connected to the bottom of the swing ring 8. The bottom of the spray heads passes through the box 17 and extends to the outside of the box 17. The swing ring 8 and the swing column 14 are both provided with cavities, and the adjacent cavities are interconnected. The spray heads are all connected to the cavities in the swing ring 8, and the liquid outlet pipes are screwed and fixedly connected to the cavities in the swing column 14.

[0054] The specific implementation process is as follows: Figure 3For example, first, the staff can separately add water and fertilizer into the first chamber and the second chamber of the storage tank 18. The staff controls the solenoid valve 20 at the discharge port of the second chamber through the controller according to the current growth state of the seedlings, so that the fertilizer can enter the mixing tank 21 through the discharge port of the second chamber. Then, the staff controls the solenoid valve 20 at the discharge port of the first chamber through the controller to add water into the mixing tank 21.

[0055] Take Figure 1 as an example. The staff can control the driving motor 13 to start through the controller. After the driving motor 13 starts, the output shaft of the driving motor 13 will drive the stirring rod 1 to rotate. As the stirring rod 1 rotates, it will drive the stirring blades 2 to stir the water and fertilizer, promoting the formation of a water-fertilizer mixture.

[0056] During the sliding process of the slide rail device, the water and fertilizer in the mixing tank 21 will constantly shake. Combining with the stirring force of the stirring blades 2 on the water and fertilizer, it can further promote the dissolution of the fertilizer in the water.

[0057] While the driving motor 13 drives the stirring blades 2 to stir, the driving motor 13 will drive the rotating rod 10 to rotate. As the rotating rod 10 rotates, the rotating rod 10 will drive the first connecting rod 9 to swing reciprocally. When the first connecting rod 9 swings reciprocally, it will drive the second connecting rod 6 to swing reciprocally. Through the reciprocal swing of the second connecting rod 6, it will drive the reciprocal swing of the third connecting rod 5. Furthermore, it drives the push rod 15 to swing reciprocally through the third connecting rod 5.

[0058] Combined with Figure 2 As shown, through the reciprocal swing of the push rod 15, it drives the piston head 16 to slide reciprocally in the piston cylinder 4. When the piston head 16 slides to the right in the piston cylinder 4, the negative pressure in the piston cylinder 4 increases. The water-fertilizer mixture in the mixing tank 21 enters the piston cylinder 4 through the liquid inlet pipe and the liquid inlet under the action of the negative pressure. When the piston head 16 slides to the left in the piston cylinder 4, the water-fertilizer mixture in the piston cylinder 4 enters the cavity in the swing column 14 through the liquid outlet and the liquid outlet pipe, and then reaches the spray head through the cavity of the swing ring 8 to spray the seedlings.

[0059] As the driving motor 13 operates, the driving motor 13 will simultaneously drive the rotating disk 12 to rotate eccentrically. When the rotating disk 12 rotates eccentrically, it will continuously push the swing ring 8 to swing up and down. As the swing ring 8 swings up and down, it will drive the swing column 14 to swing up and down. Through the up and down swing of the swing ring 8 and the swing column 14, the spray head will swing up and down synchronously during the spraying process of the water-fertilizer mixture, thus expanding the spraying area of the spray head. So that the seedlings can fully absorb the water-fertilizer mixture, thereby promoting the growth of the seedlings.

[0060] Example 2:

[0061] The difference from the above embodiment is that an anti-corrosion coating is adhesively bonded to the inner wall of the mixing tank 21, and in this embodiment, the anti-corrosion coating is selected as an epoxy resin coating.

[0062] The specific implementation process is as follows: The fertilizer in the mixing tank 21 may corrode the inner side wall of the mixing tank 21. The epoxy resin coating can effectively isolate the fertilizer from the inner side wall of the mixing tank 21, reducing metal oxidation or chemical reactions, thereby significantly extending the service life of the mixing tank 21.

[0063] Embodiment 3:

[0064] The difference from the above embodiment is that a transparent window is fixedly connected to the box body 17 by bolts.

[0065] The specific implementation process is as follows: The staff can directly check the operation status of each component in the box body 17 through the transparent window. The staff can timely discover abnormal situations, thereby quickly taking maintenance measures and improving the maintenance efficiency of the staff.

[0066] Embodiment 4:

[0067] The difference from the above embodiment is that filter nets are fixedly connected to the liquid inlet and the liquid outlet by screws.

[0068] The specific implementation process is as follows: The filter nets in the liquid inlet and the liquid outlet can filter impurities and large particle agglomerates in the water-fertilizer mixture, thereby reducing the risk of the spray head being blocked during the spraying process of the water-fertilizer mixture.

[0069] Embodiment 5:

[0070] As Figure 4 shown, a method for cultivating seedlings includes the following steps:

[0071] Step 1, seedling planting: Plant the seedlings to be cultivated in the greenhouse. Plan the planting area in the greenhouse, and adjust the row spacing and plant spacing according to the seedling type and growth requirements. Then, after stretching the seedling roots, implant them into the planting holes and cover the soil to the root collar part.

[0072] Step 2, water-fertilizer preparation: Stir in the mixing component according to the fertilizer and water required by the seedlings to prepare a water-fertilizer mixture. According to the seedling requirements, add water and fertilizer into the storage component respectively, and control the quantitative mixing and stirring of water and fertilizer in the mixing component through the controller. Ensure that the fertilizer is completely dissolved and the mixture is uniform.

[0073] Step 3, position adjustment: Drive the box body 17 to move to the seedlings that need to be fertilized through the slide rail device. Driving the box body 17 to move along the track through the slide rail device can accurately position the seedlings that need to be water-fertilized.

[0074] Step 4: Apply fertilizer: Spray the water-fertilizer mixture onto the seedlings through the spraying assembly for fertilization. The water-fertilizer mixture stirred well in the stirring assembly is sucked through the suction assembly and then extruded into the spraying assembly, and the spraying assembly is used to spray the water-fertilizer mixture. The spraying assembly is driven by the swinging assembly to swing, thereby increasing the spraying area of the spraying assembly, improving the water-fertilizer coverage rate of the seedlings, and promoting the growth and development of the seedlings.

[0075] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. The obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
