Description

Technical Field

[0001] This invention relates to the field of seedling cultivation technology, specifically to an intelligent cultivation rack for agricultural seedling cultivation. Background Technology

[0002] The existing seedling cultivation racks have the following problems:

[0003] 1. When cultivating seedlings, the roots of the seedlings are manually piled at the bottom of the cultivation pot, and then soil is filled into the cultivation pot until it is full. Then, the seedlings in the cultivation pot are watered by pouring water from the top. This method will cause the soil moisture on the surface to be different from that at the bottom, which will not accurately reflect the water shortage situation and will easily lead to problems of too much or too little watering.

[0004] 2. When the saplings reach the transplanting standard, they need to be removed from the cultivation pot. This can be done by either keeping the pot and using tools to remove the soil and saplings, or by breaking the pot to remove the soil and saplings. In the first method, the soil becomes more scattered after being removed due to the tools breaking the adhesion between the soil and the pot, resulting in poor coverage of the sapling roots and allowing air to enter, which can cause the saplings to lose their viability after subsequent planting. In the second method, the economic loss is directly caused, increasing the planting cost. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent cultivation rack for agricultural seedling raising, thus solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent cultivation rack for agricultural seedling raising, comprising:

[0007] The cultivation frame is a layered structure that forms the basis for planting seedlings. It includes a first layer, a second layer, and a third layer. Side plates are set on the side walls of the first, second, and third layers to form a layered structure from top to bottom.

[0008] The cultivation tray is equidistantly set on the cultivation frame to create a growth space for seedlings. It includes an outer sleeve on the cultivation frame, and a water guide is set inside the outer sleeve to establish a water guide path for water to flow towards the center of the outer sleeve. An inner sleeve is fitted inside the outer sleeve, and a water channel set adapted to the position of the water guide is opened on the inner sleeve to connect the water guide path of the water guide.

[0009] The difference in diameter between the outer sleeve and the inner sleeve forms a water inlet groove, and the water guide is set in the water inlet groove to guide the water into the inner sleeve.

[0010] The inner sleeve is equipped with a detachment tray to help the seedlings detach completely from the inner sleeve after cultivation.

[0011] In a single specific embodiment, the water guide includes a partition plate disposed between water inlet tanks. The partition plates divide the water inlet tanks into several water-filled cavities. A water baffle plate is disposed between adjacent partition plates. The water baffle plate extends from one partition plate to another to reduce the water inlet volume of the water-filled cavity. The extension distance of the water baffle plate between adjacent partition plates is less than the distance between adjacent partition plates, and the difference between them forms a water inlet. A reverse folding plate is disposed on the water inlet trajectory.

[0012] The reverse baffle is installed at an incline on the side wall of the partition plate and changes the flow direction of the water entering the water body from the inlet. The reverse baffle includes an installation section and an extension section. The installation end is installed horizontally, and the extension end gradually increases in height at the connection with the installation end. Its cut-off position is less than the bottom surface of the water-blocking plate.

[0013] The baffle plate consists of a top plate and a bottom plate. The top plate is inclined and its height gradually decreases as it approaches the water inlet. The bottom plate is flat and there is a distance between the bottom plate and the extension end to form a water outlet.

[0014] In a single specific embodiment, the water passage group includes a flood outlet, an extension outlet, and a drain outlet opened on the inner sleeve side wall. The flood outlet and the drain outlet are arranged alternately between adjacent extension outlets. The flood outlet, extension outlet, and drain outlet are connected to the water inlet channel and the interior of the inner sleeve.

[0015] In a single specific embodiment, the flood outlet is located above the inlet and is inclined upwards. The height of the inlet at one end of the inlet channel is less than the height of the inlet at one end of the inner sleeve, which slows down the spread of water along the flood outlet into the inner sleeve.

[0016] In a single specific embodiment, it is described that there is an extension outlet between the drain outlet and the flood outlet, the drain outlet and the flood outlet are mirror images of each other, and the height of the groove at the inlet end is greater than the height of the groove at the inner sleeve end.

[0017] The water outlet is opened horizontally.

[0018] In a single specific embodiment, the detachment disc includes a disc body that detaches from the inner sleeve synchronously with the seedling and a plurality of peeling blades circumferentially installed on the disc body. The upper ends of the plurality of peeling blades are connected to a connecting ring, which slides on the inner wall of the inner sleeve. The connecting ring is positioned at the upper end of the flood outlet.

[0019] The inner wall of the inner sleeve is provided with an inner ring groove that extends to the installation position of the connecting ring. The connecting ring is engaged with the inner ring groove wall, and the inner ring groove extends to the top of the inner sleeve.

[0020] In a single specific embodiment, the spacing between adjacent peeling pieces is greater than the width of the water trough assembly. A starting mark is engraved on the top of one peeling piece, and an indicator mark is marked on the top of the inner sleeve. The peeling piece at the point where the starting mark and the indicator mark coincide is misaligned with the water trough assembly.

[0021] Compared with the prior art, the present invention provides an intelligent cultivation rack for agricultural seedling raising, which has the following features:

[0022] Beneficial effects:

[0023] In the technical solution disclosed in this invention, the cultivation frame is first divided into layers for the seedlings that need to be cultivated. Within each layer, cultivation trays are used to divide the space into independent, detachable seedling cultivation areas. The cultivation trays set on the first, second, and third layers create a detachable and fixed structure. The fixed structure on the cultivation frame provides positioning for the detachable structure during installation. By simultaneously detaching the detachable structure of the cultivation tray from the fixed structure, the integrity of the soil covering the seedling is increased without damaging the structure of the cultivation tray, thus enabling reuse.

[0024] This invention divides the cultivation tray into an outer sleeve and an inner sleeve, and forms a water inlet trough between the outer sleeve and the inner sleeve to initially create a water intake foundation for the inner sleeve. However, given that current watering methods primarily involve injecting water from the top surface, resulting in insufficient water intake for the roots, the water guide device installed in the water inlet trough creates conditions for water to be drawn into the soil on the root surface. Combined with the synergistic effect of the water passage trough assembly in the inner sleeve, this method of directly drawing water into the soil on the root surface is more beneficial to the water absorption efficiency of the roots compared to top surface watering.

[0025] The water-bearing cavity, divided by a partition plate in the water guide component, subdivides the water inlet channel from the inlet trough to the inner sleeve into several channels. The baffle plate and the deflector plate installed in the water-bearing cavity reduce the amount of water entering the water-bearing cavity, thereby injecting water into the inlet trough from a single position. The water body generates a circumferential flow and spreads throughout the entire inlet trough, increasing the water-guiding coverage area into the inner sleeve, increasing the water inlet area into the inner sleeve, and enhancing the irrigation effect.

[0033] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-6 Existing seedling cultivation racks have problems with watering and transplanting. For example, when cultivating seedlings, the roots are manually piled at the bottom of the cultivation pot, and then soil is filled into the pot until it is full. Then, water is poured from the top of the pot to irrigate the seedlings. This method causes the soil moisture on the surface to differ from that at the bottom, resulting in an inaccurate reflection of water shortage and easily leading to problems of too much or too little watering.

[0035] For example, when saplings reach the transplanting standard, they need to be transferred out of the cultivation pot. This can be done by either keeping the pot and using tools to remove the soil and saplings, or by breaking the pot to remove the soil and saplings. In the first method, the soil becomes more scattered after being removed due to the tools breaking the adhesion between the soil and the pot, resulting in poor coverage of the sapling roots and allowing air to enter, which can cause the saplings to lose their viability after subsequent planting. In the second method, the economic loss is directly increased, increasing the planting cost.

[0036] To address the series of problems encountered in practice, this solution describes an intelligent cultivation rack for agricultural seedlings. Firstly, the cultivation rack 1 establishes layered spaces for the seedlings to be cultivated. Within each layer, cultivation trays 2 are used to create independent, detachable seedling cultivation areas. The cultivation trays 2, located on the first, second, and third layers 11, provide both detachable and fixed structures. The fixed structure on the cultivation rack 1 provides positioning for the detachable structure during installation. By simultaneously detaching the cultivation trays 2 from the fixed structure, the integrity of the soil covering the seedlings is increased without damaging the cultivation trays 2, enabling reuse.

[0037] Furthermore, based on existing irrigation problems, this invention divides the cultivation tray 2 into an outer sleeve 21 and an inner sleeve 23, and forms a water inlet trough 25 between the outer sleeve 21 and the inner sleeve 23 to first create a water intake foundation into the inner sleeve 23. With the water guide 26 set in the water inlet trough 25 creating conditions for water to be drawn into the root surface soil, and in conjunction with the water passage trough group 24 set in the inner sleeve 23, compared with the top surface water injection irrigation method, directly drawing water into the root surface soil is more conducive to the water absorption efficiency of the roots.

[0038] This solution describes an intelligent cultivation rack for agricultural seedlings, which utilizes a cultivation rack body 1 to establish a layered seedling cultivation and placement base. It includes a first layer 11, a second layer 12, and a third layer 13. Side plates are provided on the side walls of the first layer 11, second layer 12, and third layer 13 to form a layered structure from top to bottom. The first layer 11 and third layer 13 are located on the same vertical line, while the second layer 12 protrudes beyond the first layer 11 and third layer 13, forming an "I" shape. The second layer 12 has different placement positions from the first layer 11 and third layer 13, thus preventing the height of the seedlings from being obstructed by the installation height of the first layer 11. Placement grooves are provided on the first layer 11, second layer 12, and third layer 13, and sleeves are provided on the bottom walls of the first layer 11, second layer 12, and third layer 13 to fit the placement grooves.

[0039] In order to determine and establish the cultivation position of seedlings on the cultivation frame 1, this scheme sets up cultivation trays 2 on the cultivation frame 1. The trays are set at equal intervals on the cultivation frame 1 to construct the growth space of the seedlings. The trays include an outer sleeve 21 on the cultivation frame 1. A water guide 26 is set inside the outer sleeve 21 to establish a water guide path for water to flow towards the center of the outer sleeve 21. An inner sleeve 23 is fitted inside the outer sleeve 21. A water channel group 24 adapted to the position of the water guide 26 is opened on the inner sleeve 23 to connect the water guide path of the water guide 26. The difference in diameter between the outer sleeve 21 and the inner sleeve 23 forms a water inlet trough 25. The water guide 26 is set in the water inlet trough 25 and guides the water to the inner sleeve 23. The inner sleeve 23 is equipped with a detachment disc 27 to assist the seedlings in detaching completely from the inner sleeve 23 after cultivation. Both the inner sleeve 23 and the outer sleeve 21 are ring-shaped. The inner sleeve 23 and the outer sleeve 21 are the fixed structures of the cultivation tray 2, while the detachment disc 27 is a detachable structure relative to the outer sleeve 21 and the inner sleeve 23. It can rotate relative to the inner sleeve 23 and the outer sleeve 21 to release the soil from the adhesion between the soil and the inner wall of the inner sleeve 23. Because it is inside the inner sleeve 23, it releases the external rotational force that causes the soil to rotate. Therefore, compared with the separation caused by the external insertion of a tool to squeeze the soil, it can produce less impact on the soil structure.

[0040] To ensure that irrigation directly affects the root system soil, this design incorporates a water guide 26, which includes partition plates 261 positioned between water inlet troughs 25. These partition plates 261 divide the water inlet troughs 25 into several water-filled cavities 262. Water-separating plates 263 are positioned between adjacent partition plates 261. These water-separating plates 263 extend from one partition plate 261 to another, reducing the water flow into the water-filled cavities 262. The extension distance of the water-separating plates 263 between adjacent partition plates 261 is less than the distance between adjacent partition plates 261. The spacing between adjacent partition plates 261, and the difference between them, forms a water inlet. The partition plate 263 consists of a top plate and a bottom plate. The top plate is inclined, and its height gradually decreases as it approaches the water inlet. The bottom plate is flat, and a distance is left between the bottom plate and the extended end to form a water passage. The width of the water inlet formed by the spacing between the partition plate 263 and the partition plate 261 is significantly smaller than the water inlet width of the water-filled cavity 262. Therefore, when water initially enters the inlet tank 25, it enters a specific water-filled cavity 262. The speed will decrease, allowing the water to flow from one water-filled cavity 262 to the next, thus creating water flow throughout the entire inlet tank 25. This prevents water from directly rushing into a single water-filled cavity 262. However, to further increase the flow range of the water in the inlet tank 25, a deflector plate 264 is installed on the water inlet trajectory. The deflector plate 264 is installed at an angle on the side wall of the partition plate 261 and changes the flow direction of the water entering from the inlet. It includes an installation section and an extension section. The installation end is installed horizontally, and the extension end gradually increases in height at the connection point with the installation end. Its cut-off position is less than the bottom surface of the baffle plate 263. When water enters the water-filled cavity 262, it will cause water backflow due to the obstruction of the deflection plate 264, which will further reduce the speed of water entering the water-filled cavity 262 and slow down the speed of water entering the water-filled cavity 262. This lays the foundation for subsequent water to flow through this water-filled cavity 262 to the next water-filled cavity 262. The water guide 26 divides the water-filled inner cavity 262 into the partition plate 261, and subdivides the water inlet channel from the water inlet trough 25 to the inner sleeve 23 into several channels. The water baffle 263 and the anti-bend plate 264 installed in the water-filled inner cavity 262 reduce the amount of water entering the water-filled inner cavity 262, thereby injecting water into the water inlet trough 25 from a single position. The water body generates a circumferential flow and spreads throughout the entire water inlet trough 25, increasing the water inlet coverage area into the inner sleeve 23, increasing the water inlet area into the inner sleeve 23, and enhancing the irrigation effect.

[0041] The water channel assembly 24 includes a flood outlet 241, a water inlet 242, and a drain outlet 243 located on the side wall of the inner sleeve 23. The flood outlet 241 and the drain outlet 243 are spaced apart between adjacent water inlets 242. The flood outlet 241, water inlet 242, and drain outlet 243 connect the inlet channel 25 and the interior of the inner sleeve 23. The flood outlet 241 is located above the water inlet 242 and is inclined upwards. The height of the channel opening at one end of the inlet channel 25 is less than the height of the channel opening at one end of the inner sleeve 23, which slows down the flow of water along the channel. The spread speed of the flood inlet 241 into the inner sleeve 23 is such that the drain outlet 243 is separated from the flood inlet 241 by an extension outlet 242. The drain outlet 243 and the flood inlet 241 are mirror images of each other. The height of the groove at the inlet end is greater than the height of the groove at the inner sleeve 23 end. The extension outlet 242 is opened horizontally. Water passing through the flood inlet 241 will spread to the soil above the flood inlet 241 to generate irrigation water diffusion. This diffusion is flood irrigation, which occurs when the root soil is already saturated, to prevent excessive water and siltation.

[0042] To increase the integrity of the seedlings detaching from the inner sleeve 23 during the process, this solution includes a detachment disc 27 for assisted detachment. The disc 271 detaches from the inner sleeve 23 synchronously with the seedlings, and several peeling discs 272 are circumferentially installed on the disc 271. The distance between adjacent peeling discs 272 is greater than the width of the water trough assembly 24. The disc 271 is placed in the placement groove. A starting mark is marked on the top of one peeling disc 272, and an indicator mark is marked on the top of the inner sleeve 23. The peeling disc 272 at the point where the starting mark and the indicator mark coincide is misaligned with the water trough assembly 24. The peeling disc 272 located at the lower end of the placement groove is surrounded by a sleeve to prevent soil from leaking out from the gaps between the peeling discs 272. Several peeling discs 272 are connected to the upper ends of a connecting ring 273. The connecting ring 273 slides on the inner wall of the inner sleeve 23. An inner ring groove extending from the installation position of the connecting ring 273 is opened on the inner wall of the inner sleeve 23. The connecting ring 273 is locked on the groove wall of the inner ring groove, and the inner ring groove extends to the top of the inner sleeve 23. The connecting ring 273 is located at the upper end of the flood outlet 241. During planting, the soil is piled up inside the tray 271. Due to its diffusion properties, the soil extends from between the peeling plates 272 to the inner wall of the inner sleeve 23 and adheres after watering. This is the source of resistance when detaching. When detachment is needed, the operator places their hand on the bottom of the tray 271 and applies force to rotate the tray 271. At this time, the peeling plates 272 will generate a certain cutting force to cut the soil adhering to the side wall of the inner sleeve 23 and then push upward, causing the connecting ring 273 to detach from the upper end of the inner sleeve 23. At this time, the seedling wrapped in soil can be completely removed. Then, the seedling only needs to be removed from the detachment tray 27. The setting of the detachment tray has the advantage that its connection structure with the soil is smaller than that of the existing cultivation pot, and the degree of damage to the soil is less than that of the detachment of the existing cultivation pot. On the other hand, the detachment tray 27 can also be made of plastic, and its economic value will be less than that of the existing cultivation pot.
