Description

Technical Field

[0001] This invention relates to the field of vegetable cultivation technology, and more specifically, to a vegetable seedling cultivation device. Background Technology

[0002] Vegetable cultivation is an agricultural production activity that obtains vegetable crops through artificial cultivation. It covers seedling raising, field management and harvesting, and is a common practice in home gardening and organic agriculture. Its core technologies include site selection for seedling raising, temperature and light regulation, water and fertilizer management and pest and disease control. Commonly used technologies include germination and transplanting, mulching, high-ridge dense planting, vertical planting and drip irrigation systems. Fertilization often uses wood ash to supplement potassium and organic fertilizer (such as sheep manure) as base fertilizer. Soil-borne diseases are controlled through crop rotation [1-2] [7]. Modern planting models include greenhouse off-season cultivation, soilless cultivation and facility agriculture, combined with mechanized technologies such as integrated water and fertilizer and intelligent temperature control. At the same time, foam box planting is widely used due to its low cost.

[0003] Vegetable seedling cultivation is a crucial step in vegetable production. Cultivating robust seedlings through centralized and scientific methods can effectively improve yield, quality, and planting efficiency. Modern seedling cultivation has shifted from traditional small-scale farming to large-scale, standardized, and intelligent production. From sowing to emergence, the optimal temperature for most vegetables (such as solanaceous vegetables) is 20-30℃. After emergence, the temperature needs to be appropriately lowered, maintaining a daytime temperature no higher than 25℃ and a nighttime temperature no lower than 10℃ to prevent excessive vegetative growth. The temperature for celery before emergence should not exceed 25℃. However, this varies depending on the region and vegetable type. In northern regions, solanaceous vegetables (tomatoes, peppers) are typically sown from late February to early March and transplanted in mid-to-late April. In southern regions, this can be done as early as February. Cucurbit seedlings have a shorter seedling age and can be sown 10-15 days later than solanaceous vegetables. For soil-grown vegetable seedlings, when removing them from the cultivation rack, it is usually necessary to remove the seedlings along with their original root ball (root ball seedlings).

[0004] In existing technologies, seedling racks typically use plug trays for intensive seedling cultivation of high-value vegetable seedlings whose roots are highly susceptible to damage. However, after the roots of the rootstock seedlings have grown in the plug tray for a long time, they spirally wrap around the inner wall of the plug holes, forming a tight network structure. When the pulling force is large, the 'locking effect' caused by the coiled roots results in a breakage rate of 15%-20% when the robotic arm picks them up. Furthermore, traditional apical seedling pruning easily damages the base of the rootstock, leading to a low transplant survival rate. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a vegetable seedling cultivation device.

[0006] To solve the above problems, the present invention adopts the following technical solution, which can realize the airflow to blow the root system of vegetable seedlings and loosen it, so as to avoid the root system from breaking due to local stress concentration caused by the roots being twisted together when pulling the vegetable seedlings, thereby protecting the root system and reducing root hair tearing.

[0007] A vegetable seedling cultivation device includes a planting frame and two trays fixedly connected inside the planting frame. The upper side of the trays has a storage cavity, and a seedling tray is inserted into the storage cavity. An air injection component is provided inside the planting frame. The air injection component includes an air injection device fixedly connected to the lower back side of the inside of the planting rack. Two first conduits are fixedly connected to the back side of the air injection device. A movable frame is slidably connected inside the tray. The top ends of the first conduits are connected to the back side of the movable frame. Multiple nozzles are fixedly connected to the upper side of the movable frame. An electric push rod is fixedly connected to the inner back side of the tray. The telescopic end of the electric push rod is fixedly connected to the back side of the movable frame. Multiple first extension tubes are fixedly connected to the lower side of the seedling tray. Multiple mesh covers are slidably connected to the inner lower side of the seedling tray. The inside of the mesh covers is filled with gravel. Non-woven fabric is inserted into the upper side of the mesh covers.

[0008] Furthermore, the nozzle and the first extension tube are on the same horizontal line, the first extension tube extends through into the inside of the tray, the moving frame is pressed against the bottom end of the first extension tube before moving, the shape of the mesh cover is adapted to the shape of the inner cavity of the tray, the upper side of the moving frame is provided with multiple protrusions, the nozzle is located inside the protrusions, and the nozzle is provided with an external one-way check valve inside.

[0009] Furthermore, the planting rack is equipped with a water injection component inside, which includes a water supply device fixedly connected to the lower front side of the planting rack.

[0010] Furthermore, two second conduits are fixedly connected to the front side of the water supply equipment, and a transfer box is fixedly connected to the top of the second conduits. The transfer box is fixedly connected to the front side of the tray, and a filter screen is fixedly connected inside the transfer box.

[0011] Furthermore, a hollow cavity is provided on the lower side of the inside of the tray, the movable frame is slidably connected inside the hollow cavity, the first extension tube is connected to the hollow cavity, and the hollow cavity is connected to the transfer box.

[0012] Furthermore, the inner and outer sides of the tray are provided with a connecting component, which includes a drain pipe fixedly connected to the left side of the tray.

[0013] Furthermore, the drain pipe is connected to the hollow cavity, and a notch is provided on the back side of the first extension pipe, with the upper protrusion of the movable frame fitting into the notch.

[0014] Furthermore, the inner and outer sides of the tray are provided with a water-guiding assembly, which includes a cover plate that overlaps the upper side of the tray.

[0015] Furthermore, the lower side of the cover plate is pressed into contact with the upper side of the cavity plate, and multiple connecting tubes are fixedly connected to the lower side of the cover plate. Multiple sliding grooves are opened on the inner wall of the storage cavity. The connecting tubes are slidably connected inside the sliding grooves. A second extension tube is fixedly connected to the bottom end of the connecting tube. Hollow blocks are fixedly connected to both the left and right sides of the mesh cover. The second extension tube slides through the hollow block.

[0016] Furthermore, water outlets are provided at the top of the opposite sides of the connecting pipes on both the left and right sides. The shape of the hollow block is adapted to the shape of the connecting pipe. The hollow block is slidably connected inside the groove. The second extension pipe slides through the lower side of the inner cavity of the receiving cavity and is connected to the hollow cavity.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This invention uses airflow as a flexible medium to release the adhesion between the root system and the inner wall of the seedling tray by utilizing the micro-vibration effect of airflow without damaging the root network structure. Compared with mechanical ejection, the integrity of the root system is improved. It is especially suitable for seedlings of melons and fruits with fragile root systems. Because the blowing of airflow will cause the vegetable seedling roots to loosen, it avoids the root system from breaking due to local stress concentration caused by the roots intertwining when pulling the vegetable seedlings, thus protecting the root system. At the same time, in intensive seedling cultivation, the 'locking effect' caused by the roots coiling will increase the damage rate when the robot grabs the seedlings, and also prevents the traditional thimble-type seedling ejection from piercing the base of the root stem, which would lead to a decrease in the transplant survival rate.

[0018] (2) The present invention introduces water into the seedling tray through the first extension pipe, which accelerates soil softening. As the water in the hollow cavity rises, it will come into contact with the roots of the vegetable seedlings, so that the vegetable seedlings can be watered quickly. At the same time, after the plant roots absorb water, the unused nutrients (such as nitrogen and phosphorus) seep down into the water pool with the water to form a "nutrient pool" to avoid loss. The water will also accelerate soil softening, so that the root system can be reduced when pulling the vegetable seedlings.

[0019] (3) The present invention introduces water into the soil above by setting a connecting pipe. Since the second extension pipe passes through the receiving cavity and is connected to the hollow cavity, the position and range of water entering the seedling tray can be changed, so that the water can be more evenly distributed in the seedling tray to meet the growth needs of different parts of the vegetable seedling. At the same time, the gravel and non-woven fabric set inside the net can filter and buffer the water flow to prevent the water flow from being too large and impacting the root system of the vegetable seedling.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 8 A vegetable seedling cultivation device includes a planting frame 1 and two trays 13 fixedly connected inside the planting frame 1. The upper side of the trays 13 is provided with a storage cavity 11, and a seedling tray 12 is inserted into the storage cavity 11. An air injection component 2 is provided inside the planting frame 1. The aeration component 2 includes an aeration device 21 fixedly connected to the back side of the lower end inside the planting rack 1. Two first conduits 22 are fixedly connected to the back side of the aeration device 21. A movable frame 23 is slidably connected inside the tray 13. The top end of the first conduits 22 is connected to the back side of the movable frame 23. Multiple nozzles 24 are fixedly connected to the upper side of the movable frame 23. An electric push rod 25 is fixedly connected to the back side of the inside of the tray 13. The telescopic end of the electric push rod 25 is fixedly connected to the back side of the movable frame 23. Multiple first extension tubes 26 are fixedly connected to the lower side of the seedling tray 12. Multiple mesh covers 27 are slidably connected to the lower side of the inside of the seedling tray 12. The inside of the mesh cover 27 is provided with gravel 28. Non-woven fabric 29 is inserted into the upper side of the mesh cover 27.

[0024] The nozzle 24 and the first extension tube 26 are on the same horizontal line. The first extension tube 26 extends through into the inside of the tray 13. Before the moving frame 23 moves, it presses against the bottom end of the first extension tube 26. The shape of the mesh cover 27 is adapted to the shape of the inner cavity of the cavity tray 12. Multiple protrusions are provided on the upper side of the moving frame 23. The nozzle 24 is located inside the protrusions. An external one-way check valve is provided inside the nozzle 24.

[0025] By adopting the above technical solution, firstly, the gas injection device 21 is started, and then gas is delivered into the tray 13 through the two first conduits 22 on its back side. At this time, the electric push rod 25 is in the initial state, and the nozzle 24 set above the moving frame 23 is located at the bottom end of the first extension tube 26. Before the moving frame 23 moves, it presses against the bottom end of the first extension tube 26. The protrusion on the upper side of the moving frame 23 fits with the notch 362 opened on the back side of the first extension tube 26. At the same time, the first extension tube 26 is connected to the inside of the cavity tray 12, so that the gas delivered by the device passes through the first conduit 22 and the moving frame 23 in sequence, and finally sprays out from the multiple nozzles 24 fixed on the upper side of the moving frame 23 and enters the cavity tray 12. The gas will pass through the first conduit 22 and the moving frame 23 in sequence, and finally spray out from the multiple nozzles 24 fixed on the upper side of the moving frame 23 and enter the inside of the cavity tray 12. After passing through the net cover 27, gravel 28, and non-woven fabric 29, the airflow impacts the tangled roots of the vegetable seedlings in the seedling tray 12, causing the roots to loosen due to airflow disturbance. This breaks the tight mesh structure formed by the spiral entanglement of the roots around the inner wall of the seedling hole. After the treatment is completed, the electric push rod 25 retracts, driving the moving frame 23 back to its initial position, and the first extension tube 26 is unsealed. The airflow causes the vegetable seedling roots to loosen, preventing them from breaking due to local stress concentration caused by the roots intertwining when pulling the seedlings, thus protecting the roots. At the same time, in intensive seedling cultivation, the 'locking effect' caused by the entanglement of the roots will increase the damage rate when the robotic arm grasps the seedlings, and also prevent the traditional apical seedling piercing of the root base, which would lead to a decrease in the transplant survival rate.

[0026] like Figures 3 to 5 As shown, the planting rack 1 is equipped with a water injection component 3 inside, which includes a water supply device 31 fixedly connected to the front side of the lower end inside the planting rack 1.

[0027] Two second conduits 32 are fixedly connected to the front side of the water supply equipment 31. A transfer box 34 is fixedly connected to the top of the second conduits 32. The transfer box 34 is fixedly connected to the front side of the tray 13. A filter screen 35 is fixedly connected inside the transfer box 34.

[0028] A hollow cavity 33 is provided on the lower side of the inside of the tray 13. The movable frame 23 is slidably connected inside the hollow cavity 33. The first extension tube 26 is connected to the hollow cavity 33, and the hollow cavity 33 is connected to the transfer box 34.

[0029] By adopting the above technical solution, after the water supply equipment 31 is started, water is transported to the transfer box 34 through two second conduits 32 fixed on the front side. Since the transfer box 34 is fixedly connected to the front side of the tray 13, and a filter screen 35 is fixed inside it, the filter screen 35 filters the water after it enters the transfer box 34, removing impurities and preventing them from entering the seedling tray 12 and affecting the growth of the vegetable seedlings. It also filters impurities carried by the counter-current water source. The filtered water enters the hollow cavity 33 through the connection between the transfer box 34 and the hollow cavity 33 inside the tray 13. Meanwhile, the lower side of the seedling tray 12... The first extension pipe 26 is connected to the hollow cavity 33. Water will further enter the inside of the seedling tray 12 through the first extension pipe 26, but will not submerge the root system inside the seedling tray 12. When the water in the seedling tray 12 reaches an appropriate amount, the operation of the water supply device 31 will be stopped. When a large amount of water is needed, water can be injected into the hollow cavity 33 again through the water supply device 31, so that the water source gradually passes through the net cover 27, the gravel 28 and the non-woven fabric 29 and comes into contact with a small amount of soil. However, at this time, the moving seat needs to be pulled by the electric push rod 25 so that the moving frame 23 is separated from the first extension pipe 26. It should be noted that before aeration, the drain pipe 361 needs to be opened to drain the liquid accumulated in the hollow cavity 33 to prevent liquid from flowing back into the nozzle 24. After the liquid is drained, aeration can begin. The external one-way check valve inside the nozzle 24 can prevent water from flowing back. As the water level rises, the water inside the hollow cavity 33 will come into contact with the roots of the vegetable seedlings, allowing the seedlings to be watered quickly. At the same time, after the plant roots absorb water, unused nutrients such as nitrogen and phosphorus seep down into the water tank, forming a "nutrient pool" to prevent loss. The water will also accelerate soil softening, which reduces root breakage when pulling the vegetable seedlings.

[0030] like Figures 1 to 3 As shown, the inner and outer sides of the tray 13 are provided with a connecting component 36, which includes a drain pipe 361 fixedly connected to the left side of the tray 13.

[0031] The drain pipe 361 is connected to the hollow cavity 33. The back side of the first extension pipe 26 has a notch 362, and the upper protrusion of the movable frame 23 fits into the notch 362.

[0032] By adopting the above technical solution, the drain pipe 361 fixed on the left side of the tray 13 is connected to the hollow cavity 33. When it is necessary to drain the seedling tray 12, the excess water in the hollow cavity 33 will be discharged to the outside of the tray 13 through the drain pipe 361 to prevent excessive water accumulation in the seedling tray 12 from causing the roots of the vegetable seedlings to rot. At the same time, the notch 362 opened on the back side of the first extension pipe 26 and the cooperation with the protrusion on the upper side of the movable frame 23 not only play the role of connecting the gas channel when injecting air, but also ensure that water can smoothly enter the seedling tray 12 through the first extension pipe 26 when injecting water. Since the water inside the hollow cavity 33 will permeate into the soil of the hollow layer after evaporation, it will provide continuous water for the plant roots, thereby reducing the need for frequent watering. At the same time, the evaporation inside the hollow cavity 33 can increase the humidity of the surrounding air, reduce the temperature, and alleviate the stress of high temperature on vegetables.

[0033] like Figure 4 and Figure 6 and Figure 8 As shown, the inner and outer sides of the tray 13 are provided with a water guiding assembly 37, which includes a cover plate 371 that overlaps the upper side of the tray 13.

[0034] The lower side of the cover plate 371 is pressed into contact with the upper side of the cavity plate 12. Multiple connecting pipes 372 are fixedly connected to the lower side of the cover plate 371. Multiple sliding grooves 373 are opened on the inner side wall of the storage cavity 11. The connecting pipes 372 are slidably connected inside the sliding grooves 373. The bottom end of the connecting pipes 372 is fixedly connected to a second extension pipe 374. Hollow blocks 375 are fixedly connected to both the left and right sides of the mesh cover 27. The second extension pipe 374 slides through the hollow block 375.

[0035] Water outlets 376 are provided at the top of the opposite sides of the connecting pipes 372 on both the left and right sides. The shape of the hollow block 375 is adapted to the shape of the connecting pipe 372. The hollow block 375 is slidably connected to the inside of the groove 373. The second extension pipe 374 slides through the lower side of the inside of the receiving cavity 11. The second extension pipe 374 is connected to the hollow cavity 33.

[0036] By adopting the above technical solution, the cover plate 371 overlaps the upper side of the tray 13, and its lower side presses against the upper side of the cavity tray 12, which serves to fix the cavity tray 12 and prevent water from overflowing. At the same time, after the multiple connecting pipes 372 fixed on the lower side of the cover plate 371 are inserted into the slide groove 373, the second extension pipe 374 fixed at the bottom end of the connecting pipe 372 will also pass through the hollow block 375 and enter the interior of the hollow cavity 33. When water is injected, after water enters the hollow cavity 33 through the water supply device 31, some water will enter the connecting pipe 372 through the second extension pipe 374, and the water will flow through the left and right sides. The top of the opposite side of the connecting pipe 372 is provided with a water outlet 376. Water flows out from the water outlet 376 and drips evenly into the seedling tray 12 and reaches the soil. Since the second extension pipe 374 passes through the receiving cavity 11 and is connected to the hollow cavity 33, the position and range of water entering the seedling tray 12 can be changed, so that the water can be more evenly distributed in the seedling tray 12 to meet the growth needs of different parts of the vegetable seedling. At the same time, the gravel 28 and non-woven fabric 29 set inside the net cover 27 can filter and buffer the water flow to prevent the water flow from being too large and impacting the roots of the vegetable seedling.

[0037] Working principle: When this vegetable seedling cultivation device is working, the water injection component 3 sends water through the second conduit 32 into the transfer box 34 for filtration, and then into the hollow cavity 33 of the tray 13. The water then flows through the first extension pipe 26 into the seedling tray 12 to supply water for the vegetable seedlings. When there is excess water, it is discharged through the drain pipe 361 connected to the hollow cavity 33. When not supplying water, the water inside the hollow cavity 33 evaporates, and the resulting water vapor is absorbed by the soil. During air injection, the air injection device 21 supplies air to the moving frame 23 through the first conduit 22. The electric push rod 25 pushes the moving frame 23 to... The first extension pipe 26 is connected to the movable frame 23. Gas enters the seedling tray 12 from the nozzle 24 through the first extension pipe 26, impacting and loosening the entangled roots. At the same time, the cover plate 371 is connected to the seedling tray 12. The connecting pipe 372 passes through the second extension pipe 374 through the lower inner wall of the seedling tray 12 and the storage groove, so that water enters the connecting pipe 372 through the hollow cavity 33 and the second extension pipe 374, and drips evenly into the seedling tray 12 from the water outlet 376. When the water flows out, it is filtered and buffered by the gravel 28 and non-woven fabric 29 inside the mesh cover 27.
