Description

Technical Field

[0001] The invention relates to the technical field of agricultural seedling cultivation, and in particular to a seedling cultivation box. Background Art

[0002] A seedling box is a piece of equipment specially used for raising plant seedlings. It provides ideal growing conditions for seeds of flowers, vegetables, fruits and other plants in a greenhouse environment.

[0003] A Chinese patent with application number CN202210895213.X discloses an intelligent seedling raising device for municipal gardens, in which the device body is longitudinally fixedly installed at the top center position of the mounting base, and a seedling raising board is transversely installed at the inner center position of the device body, and hydraulic cylinders are fixedly installed on both sides of the inner center position of the mounting base, and piston rods are added to the telescopic ends of the tops of the hydraulic cylinders, and the tops of the piston rods extend upward through the outer walls of the mounting base and the device body, and the tops of the piston rods are connected to the seedling raising boards through stabilizing devices. The hydraulic cylinder in the above patent drives the connected stabilizing device and seedling raising board to rise and fall through the piston rod, and the sliding rods connected on both sides of the seedling raising board slide up and down in the slide groove. In this way, it is convenient to adjust the space for seedling raising, and avoid the phenomenon of insufficient development of seedlings due to insufficient living space after growth.

[0004] However, the above mechanism can only adjust the height of the two seedling raising boards, but cannot adjust the width of the seedling raising boards.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0040] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0041] like Figures 1 to 13 As shown, a seedling raising box of the present invention comprises: a seedling raising box 1, a seedling raising pot 2, a control module 3 for adjusting the spacing between the seedling raising pots 2 according to the growth cycle of the seedlings, a spraying module 4 for irrigating the seedlings, and an adjustment module 5 for adjusting the spraying amount and the spraying intensity after the spacing between the seedling raising pots 2 is changed;

[0042] When the nursery box 1 is needed for nurserying, the staff starts the regulating module 3 to gradually move the distance between the nursery pots 2 away, and when the distance is moved to the maximum, it turns to slow circumferential rotation to ensure that each nursery pot 2 can pass through the opening area specially provided in the nursery box 1 in turn, so that it is convenient for the staff to plant each nursery pot 2, and there will be no inconvenience in planting due to being close to the inside of the box;

[0043] As the growth cycle of the seedlings changes, the space required for the growth of the seedlings continues to increase, so the distance between the seedling pots 2 continues to increase. At this time, the staff only needs to start the control module 3 according to the growth of the seedlings, and the control module 3 adjusts the seedling box 1 to the most suitable spacing for the growth of the seedlings, thereby preventing the seedlings from being hindered by the seedling pots 2 and affecting their growth, which not only promotes the healthy growth of the seedlings, but also takes into account the saving of space resources;

[0044] When it is necessary to water the seedlings in the nursery pot 2, the control module 3 is also started. When the nursery pot 2 moves on the support frame 31 to the end of the movement direction, the support frame 31 is forced to rotate accordingly. When the support frame 31 rotates, the capsule 43 in the spray module 4 is squeezed synchronously, so that when the nursery pot 2 rotates to the lower end of the nozzle 41 with the support frame 31, the capsule 43 is released under pressure to accurately spray water into the nursery pot 2, thereby further reducing water waste when using a group of nozzles 41.

[0045] Finally, since the amount and intensity of water spraying are crucial factors affecting the growth of seedlings at different stages of seedling cultivation, by setting the adjustment module 5, when the seedlings grow to different periods, the required water amount and spraying intensity are adaptively adjusted.

[0046] The control module 3 includes: a support frame 31 rotatably mounted in the seedling box 1, the seedling basin 2 is slidably mounted on the support frame 31, a rotating disk 32 that drives the seedling basin 2 to slide on the support frame 31 when rotating, and a driving component that drives the rotating disk 32 to rotate, the rotating disk 32 is rotatably mounted on the side wall of the seedling box 1, a guide groove 34 is provided on the rotating disk 32, and a connecting rod 35 fixedly connected to the seedling basin 2 passes through the guide groove 34 on the rotating disk 32; the driving component is composed of a motor 331, a gear 332, and a gear ring 333; the gear 332 is coaxially fixedly connected to the output shaft of the motor 331, and the gear ring 333 is fixedly connected to the rotating disk 32; the gear 332 is meshed with the gear ring 333;

[0047] The support frame 31 is composed of a rotating rod 311 and a guide plate 312. The rotating rod 311 is rotatably installed on one side of the seedling box 1. A cavity 315 for providing gas flow is provided inside the rotating rod 311. The guide plate 312 is fixedly connected to the rotating rod 311, and a sliding groove 313 is provided on the guide plate 312; the seedling basin 2 is composed of a basin body 21, a tripod 22, a fixed rod 23, and a slider 24; the basin body 21 is fixedly connected to the tripod 22, the tripod 22 is rotatably connected to the fixed rod 23, the fixed rod 23 is fixedly connected to the slider 24, the slider 24 is slidably installed in the sliding groove 313, and the connecting rod 35 is fixedly connected to the slider 24.

[0048] When the distance between the seedling pots 2 needs to be adjusted, the motor 331 is started, and the motor 331 synchronously drives the gear 332 to rotate. Considering that the speed required in this patent does not need to be very fast, a reducer is provided on the output shaft of the motor 331. When the gear 332 rotates, the driving gear ring 333 and the rotating disk 32 fixedly connected to the gear ring 333 rotate. When the rotating disk 32 rotates, the connecting rod 35 passing through the guide groove 34 on the rotating disk 32 is driven by the extrusion force of the guide groove 34. At the same time, the slider 24 fixedly connected to the other end of the connecting rod 35 is limited by the sliding groove 313. When the rotating disk 32 rotates, the slider 24 slides along the sliding groove 313, thereby solving the problem of increasing the distance between the seedling pots 2.

[0049] When the seedling pot 2 needs to be rotated to the lower end of the nozzle 41 to wait for spraying, the motor 331 drives the rotating disk 32 to rotate continuously. When the slider 24 moves along the sliding groove 313 to the end of the sliding groove 313, the force driving the slider 24 to slide will be fully applied to the support frame 31. The support frame 31 is subjected to the full force applied by the rotating disk 32, and thus rotates synchronously. It should be added here that the support frame 31 and the rotating disk 32 are both rotatably mounted on the side wall of the seedling box 1, and the damping force when the support frame 31 and the side wall of the seedling box 1 rotate The rotation force is greater than the rotation force generated on the support frame 31 when the sliding block 24 is driven to slide along the sliding groove 313 when the rotating disk 32 rotates; thus, when the motor 331 just starts to rotate, the rotating disk 32 will only drive the sliding block 24 to slide in the sliding groove 313, and will not synchronously drive the support frame 31 to rotate synchronously with the rotating disk 32. When the sliding block 24 moves to the end of the sliding groove 313, the support frame 31 rotates accordingly due to the full force applied by the rotating disk 32; thereby, the seedling pots 2 are transported to the lower end of the nozzle 41 in sequence, so as to facilitate spraying the seedling pots 2.

[0050] It should be added here that, by setting the seedling pot 2 to be rotatable, on the one hand, the seedling raising space can be significantly increased and the seedling raising quantity per unit area can be increased; on the other hand, the support frame 31 is driven by the motor 331 so that the seedling pot 2 can be rotated regularly to ensure that the seedlings in each layer and each position can receive uniform light and spraying, which helps to avoid the problem of seedling growth differences caused by uneven light and spraying in traditional seedling raising methods.

[0051] It should be added here that the basin body 21 is rotatably connected to the fixing rod 23 via the tripod 22. Since the triangle shape has high stability and the basin body 21 itself is relatively heavy, when the support frame 31 rotates, the basin body 21 will not tilt or overturn with the rotation of the support frame 31.

[0052] In the relatively closed seedling box 1, as photosynthesis continues, the carbon dioxide concentration in the seedling box will gradually decrease; if the carbon dioxide supply is insufficient, the rate of photosynthesis will be limited, which will in turn affect the growth rate and development quality of the plants; in order to maintain the stability of the carbon dioxide concentration in the seedling box and promote the photosynthesis efficiency of the plants, we need to regularly fill the seedling box with carbon dioxide.

[0053] The control module 3 also includes: a delivery component that delivers gas into the seedling box 1 as the support frame 31 rotates;

[0054] The conveying assembly includes: a storage box 364 for storing gas, an air outlet 365 opened on the storage box 364, a reciprocating screw 361 fixedly installed on the storage box 364, a piston 362 threadedly connected to the reciprocating screw 361, one end of the rotating rod 311 rotatably installed at the air outlet 365, the piston 362 is slidably installed in the cavity 315 of the rotating rod 311, and an air outlet hole 314 is opened on the rotating rod 311.

[0055] When it is necessary to replenish carbon dioxide into the seedling box 1, it is only necessary to inject dry ice or carbon dioxide gas into the storage box 364 and open the valve at the air outlet 365. When the rotating rod 311 rotates, the piston 362 in the cavity 315 of the rotating rod 311 rotates synchronously with the rotating rod 311. Since the piston 362 is also threadedly connected to the reciprocating screw rod, and the reciprocating screw rod 361 is located in the cavity 315, when the piston 362 rotates with the rotating rod 311, the piston 362 moves back and forth in the cavity 315 of the rotating rod 311 under the guidance of the reciprocating screw rod 361, and then the carbon dioxide gas in the storage box 364 is drawn from the storage box 364 into the cavity 315 of the rotating rod 311, and then discharged into the seedling box 1 through the air outlet 314 opened on the rotating rod 311, so as to replenish the carbon dioxide in the seedling box 1.

[0056] It should be noted here that the piston 362 in the present application is a double piston 362 head structure, and the double piston 362 heads are connected by a fixing part in the middle, and there is a certain distance between the double piston 362 heads. When the piston 362 moves back and forth with the reciprocating screw 361, carbon dioxide is extracted by the piston 362 head near the storage box 364, and released to the inside of the seedling box 1 through the air outlet 314. At the same time, when the piston 362 head at the other end moves synchronously, the gas on one side of the seedling box 1 can be effectively extracted into the cavity 315 of the rotating rod 311 again, and released to the other side of the seedling box 1 through the air outlet 314 as the piston 362 head at the other end moves, forming a gas circulation in the seedling box 1, thereby effectively realizing the exchange of gases on both sides of the seedling box 1, accelerating the mixing of carbon dioxide and the gas in the box, and making it more uniform.

[0057] The spray module 4 includes: a nozzle 41 fixedly mounted on the top of the inner cavity of the seedling box 1, a water tank 42 fixedly mounted on the top of the seedling box 1, a capsule 43 that absorbs an equal amount of water in the water tank 42, and synchronously squeezes the water in the capsule 43 to an extrusion piece 44 in the nozzle 41 as the seedling pot 2 rotates, and the extrusion piece 44 is fixedly connected to the connecting rod 35; the capsule 43, the nozzle 41 and the water tank 42 are interconnected through a hose 45, and the water inlet of the capsule 43 is fixedly connected to the water tank 42 through the hose 45, and the water outlet of the capsule 43 is fixedly connected to the nozzle 41;

[0058] When the motor 331 drives the rotating disk 32 to rotate, the extrusion piece 44 fixedly installed on one side of the connecting rod 35 rotates with the rotating disk 32. When the seedling basin 2 rotates to the lower end of the nozzle 41, the extrusion piece 44 synchronously moves to the lower end of the capsule 43, and synchronously squeezes the capsule 43 to spray the water in the capsule 43 into the seedling basin 2 through the nozzle 41, so as to spray the seedlings in the seedling basin 2. When the extrusion piece 44 does not squeeze the capsule 43, the capsule 43 draws water from the water tank 42. By setting the capsule 43, the amount of liquid sprayed on the seedling basin 2 each time can be accurately controlled, thereby preventing problems such as waterlogging and root rot caused by excessive watering. At the same time, each time the seedling basin 2 moves to the lower end of the nozzle 41, the extrusion piece 44 will squeeze the capsule 43, so that the water sprayed by the nozzle 41 each time can be accurately sprayed into the seedling basin 2, further reducing the waste of water resources.

[0059] At different stages of seedling cultivation, the amount and intensity of water spraying are crucial factors affecting the growth of seedlings:

[0060] Seed germination period: The seeds have a relatively low demand for water in the early stages of germination, but keeping the soil slightly moist is the key. Too much water may cause the seeds to rot and affect the germination rate. Gentle water spraying can avoid washing away the fine soil or matrix covering the seeds, protecting the seeds and promoting uniform germination.

[0061] Seedling growth period: As the seedlings grow, their demand for water gradually increases. At this time, the amount of water spraying should be appropriately increased to meet the needs of rapid growth of the seedlings; it is necessary to ensure that the water can evenly penetrate into the deep soil layer to nourish the root system, while avoiding excessive water flow to impact the seedlings and cause damage.

[0062] Seedling stage and before transplanting: Use rainwater irrigation similar to that in the natural environment to help the seedlings enhance their drought resistance. Therefore, a larger amount of water and spraying intensity are required. At the same time, a larger spraying intensity can also clean the dust and dirt on the leaves, improve the photosynthesis efficiency of the leaves, and promote the growth of seedlings.

[0063] Therefore, as the seedlings grow, the requirements for water volume and spraying intensity gradually increase.

[0064] The adjustment module 5 includes: a distance sensor for monitoring the moving distance of the seedling box 1 on the support frame 31, a water volume adjustment unit for adjusting the water output of the capsule 43 according to the moving distance of the seedling box 1, and a nozzle 41 adjustment unit for adjusting the spraying force of the nozzle 41; the water volume adjustment unit is composed of an electric push rod 51, a slide rail 52, and a mounting plate 53; the mounting plate 53 is fixedly connected to the capsule 43, the mounting plate 53 is slidably mounted on the slide rail 52, and the telescopic end of the electric push rod 51 is fixedly connected to the mounting plate 53;

[0065] After the spacing of the seedling pots 2 is adjusted by the control module 3 in different growth cycles of the seedlings, the slider 24 will stay at different positions of the sliding groove 313. Before the seedlings need to be sprayed, the distance sensor measures the distance moved by the slider 24 from this position to the end of the sliding groove 313. The measured distance is analyzed and converted into the telescopic length required by the cylinder. When the spraying amount needs to be increased, the cylinder pushes the mounting plate 53 and the capsule 43 mounted on the mounting plate 53 to move downward, so that the extrusion member 44 increases the extrusion depth when squeezing the capsule 43, so that the extrusion member 44 can squeeze more water in the capsule 43 when squeezing the capsule 43 once, thereby meeting the problem of increasing water demand as the seedlings grow.

[0066] It should be noted here that the specific model of the distance sensor mentioned in this application is preferably: LS-300.

[0067] As an optional solution of this embodiment, the number of rotations of the support frame 31 may be increased so that the seedling pot 2 is sprayed multiple times.

[0068] The nozzle 41 adjustment unit includes: a driven rod 54 fixedly connected to the mounting plate 53, and a sleeve 55 slidably mounted on the nozzle 41; the driven rod 54 is fixedly connected to the sleeve 55; the nozzle 41 is composed of an atomizing head 411 and a spray hole 412 opened on the side wall of the nozzle 41; the diameter of the spray hole 412 decreases from top to bottom, and the sleeve 55 covers the spray hole 412, and an annular nozzle 551 is opened on the side wall of the sleeve 55;

[0069] When the mounting plate 53 moves downward, it drives the capsule 43 downward and drives the driven rod 54 to move downward synchronously, and the sleeve 55 slides downward along the nozzle 41. At this time, the spray holes 412 opened on the side wall of the nozzle 41 leak out from the nozzle 551 of the sleeve 55 in order from large to small, and only one row of spray holes 412 leaks out from the sleeve 55. The water in the nozzle 41 can only be sprayed out from the atomizing head 411 with smaller pores, thereby meeting the large demand for moistening the soil layer, and at the same time, the soil layer will not be compacted due to excessive water pressure impact, which will affect the germination of seeds breaking through the soil layer.

[0070] The present invention also includes a specific method for adjusting the spraying amount and the spraying intensity: the staff determines the appropriate distance between the seedling pots 2 according to the growth cycle of the seedlings; then the adjustment module 5 is started to move the seedling pot 2 from the initial position of the support frame 31 to a position suitable for the growth of the seedlings at this stage; when spraying is required, the adjustment module 5 is started again, and the seedling pot 2 moves from the moved position to the end of the stroke, and then rotates synchronously with the rotating disk 32; the distance sensor measures and records the distance that the seedling pot 2 moves from different positions to the end of the stroke, and transmits the measurement result to the computer; the computer analyzes the amount of spray liquid and the spraying intensity required at this stage according to the distance moved by the seedling pot 2, converts it into the distance that the electric push rod 51 needs to extend, and transmits the calculated distance to the control valve of the electric push rod 51; the control valve controls the electric push rod 51 to push out the corresponding distance, and adjusts the spraying water volume and the spraying intensity through the adjustment module 5.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art.
