Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, and in particular to an intelligent cultivation rack for agricultural seedling cultivation. Background Art

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

[0003] 1. When cultivating saplings, the roots of the saplings are manually piled at the bottom of the cultivation pot, and then the soil is filled into the cultivation pot. After the cultivation pot is filled, the seedlings in the cultivation pot are watered by top filling. This method will cause the soil moisture on the soil surface to be different from the soil moisture at the bottom, and the water shortage condition is not reflected accurately, which is easy to cause the problem of too much or too little pouring.

[0004] 2. When the seedlings reach the transplanting standards, they need to be transferred out of the cultivation pots. Either the pots can be retained and the soil and seedlings can be taken out using tools, or the pots can be destroyed to take out the soil and seedlings. In the first method, after the transfer, the soil will be more scattered due to the destruction of the adhesion between the soil and the pot by the tools, and the root system of the seedlings will not be strongly wrapped, resulting in wind ingress and inactivation of the seedlings during subsequent planting. The second method will directly cause economic losses and increase planting costs. Summary of the invention

[0012] The inverted plate is installed on the side wall of the partition plate in an inclined shape and changes the flow direction of the water entering the water body from the water inlet. The inverted plate includes a mounting section and an extension section. The mounting end is installed horizontally. The extension end gradually increases in height from the point where it connects with the mounting end, and its end position is smaller than the bottom surface of the water barrier.

[0013] The water-blocking plate is composed 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 spaced a distance from the extension end to form a water outlet.

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

[0022] Beneficial effects:

[0023] In the technical solution disclosed in the present invention, firstly, a cultivation frame is provided with a layered space for the seedlings to be raised, and cultivation trays are used to divide the single-layer space into partitions to form an independent and detachable seedling cultivation area, and the cultivation trays arranged on the first layer, the second layer and the third layer are used to produce a detachable and fixed structure. The fixed structure arranged on the cultivation frame produces a positioning effect during the installation of the detachable structure. The detachable structure of the cultivation tray is synchronously separated from the fixed structure to increase the integrity of the soil wrapped around the seedlings without destroying the cultivation tray structure, thereby achieving reuse.

[0024] The present invention divides the cultivation tray into an outer sleeve and an inner sleeve, and forms a water inlet groove between the outer sleeve and the inner sleeve to firstly generate a basis for diverting water into the inner sleeve. However, in the current watering process, water is basically injected from the top surface, resulting in insufficient water intake by the roots that need water. The water guide member arranged in the water inlet groove generates the condition for diverting water to the soil on the root surface, and cooperates with the water trough group arranged in the inner sleeve. Compared with the top surface watering method, diverting water directly to the soil on the root surface is more beneficial to the water absorption efficiency of the roots.

[0025] The water-containing inner cavity divided by the partition plate in the water-guiding member subdivides the water inlet channel from the water inlet trough to the inner sleeve into a plurality of channels, wherein the baffle plate and the inflection plate installed in the water-containing inner cavity reduce the amount of water entering the water-containing inner cavity, thereby injecting water into the water inlet trough from a single position, and the water body generates annular flow and spreads throughout the entire water inlet trough, thereby increasing the water diversion coverage into the inner sleeve, increasing the water inlet area into the inner sleeve, and enhancing the irrigation effect.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 6 In the existing sapling cultivation rack, there are problems caused by watering and transplanting: for example, when cultivating saplings, the roots of the saplings are manually piled at the bottom of the cultivation pot, and then the soil is filled into the cultivation pot to fill the cultivation pot. Then, the seedlings in the cultivation pot are watered by top filling. This method will cause the soil moisture on the soil surface to be different from the soil moisture at the bottom, and the water shortage condition reflected is not true, which is easy to cause the problem of too much or too little pouring.

[0035] For example, when the saplings reach the transplanting standard, they need to be transferred out of the cultivation pots. Alternatively, the pots can be retained and the soil and saplings can be taken out using tools, or the pots can be destroyed to take out the soil and saplings. In the first method, after the transfer, the soil will be more scattered due to the destruction of the adhesion between the soil and the pot by the tools, and the root system of the saplings will not be strongly wrapped, resulting in wind ingress and inactivation of the saplings during subsequent planting. The second method will directly cause economic losses and increase planting costs.

[0036] In response to the above series of problems arising in the practical process, this scheme describes an intelligent cultivation rack for agricultural seedling cultivation, which first establishes a layered space for the seedlings that need to be cultivated on the cultivation frame 1, and uses the cultivation tray 2 to divide the single-layer space into partitions to form an independent and detachable seedling cultivation area, and uses the cultivation tray 2 arranged on the first layer 11, the second layer 12 and the third layer 13 to produce a detachable and fixed structure. The fixed structure arranged on the cultivation frame 1 produces a positioning effect during the installation of the detachable structure. The detachable structure of the cultivation tray 2 can be synchronously separated from the fixed structure to increase the integrity of the soil wrapped around the seedlings without destroying the structure of the cultivation tray 2, thereby achieving reuse.

[0037] In addition, based on the existing irrigation problems, the present invention divides the cultivation tray 2 into an outer sleeve 21 and an inner sleeve 23, and forms a water inlet groove 25 between the outer sleeve 21 and the inner sleeve 23, thereby firstly creating a water diversion basis into the inner sleeve 23, and on the basis of the water guide member 26 arranged in the water inlet groove 25 creating the conditions for diverting water to the soil on the root surface, in coordination with the water trough group 24 opened in the inner sleeve 23, compared with the top surface watering method, directly diverting water to the soil on the root surface is more beneficial to the water absorption efficiency of the roots.

[0038] The present invention describes an intelligent cultivation rack for agricultural seedling cultivation, which uses a cultivation rack body 1 to establish a cultivation and placement foundation for stacked seedlings, and includes a first layer board 11, a second layer board 12 and a third layer board 13. Side panels are arranged on the side walls of the first layer board 11, the second layer board 12 and the third layer board 13 to form a layered structure of the first layer board 11, the second layer board 12 and the third layer board 13 from top to bottom, wherein the positions of the first layer board 11 and the third layer board 13 are located on the same vertical line, and the second layer board 12 protrudes from the first layer board 11 and the third layer board 13 to form a] shape, and the second layer board 12 has a different placement position from the first layer board 11 and the third layer board 13, so that the height of the seedlings is not blocked based on the installation height of the first layer board 11, and placement grooves are opened on the first layer board 11, the second layer board 12 and the third layer board 13, and a wrapping cover is arranged on the bottom wall of the first layer board 11, the second layer board 12 and the third layer board 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 arranges cultivation trays 2 on the cultivation frame 1, which are equidistantly arranged on the cultivation frame 1 to construct a growth space for seedlings, and include an external sleeve 21 on the cultivation frame 1, and a water guide member 26 is arranged in the external sleeve 21 to establish a water guide path for water to flow toward the center direction of the external sleeve 21, an inner sleeve 23 is connected to the inside of the external sleeve 21, and a water trough group 24 adapted to the position of the water guide member 26 is opened on the inner sleeve 23 to connect the water guide path of the water guide member 26, and the difference in diameter between the external sleeve 21 and the inner sleeve 23 forms a water inlet groove 25, and the water guide member 26 is arranged in the water inlet groove 25 and guides the water to the inner sleeve 23. A detachment tray 27 is provided in the inner sleeve 23 to assist the seedlings to completely detach from the inner sleeve 23 after cultivation. The inner sleeve 23 and the outer sleeve 21 are both annularly arranged. The inner sleeve 23 and the outer sleeve 21 are fixed structures of the cultivation tray 2, and the detachment tray 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 bonding state between the soil and the inner wall of the inner sleeve 23, because it itself is inside the inner sleeve 23 to release the rotational force applied from the outside to rotate the soil, thereby producing less impact on the soil structure than the separation after the tool is inserted from the outside to squeeze the soil.

[0040] In order to realize the irrigation operation directly acting on the root soil, the present scheme sets up a water guide 26, which includes a partition plate 261 arranged between the water inlet grooves 25, and a plurality of partition plates 261 divide the water inlet grooves 25 into a plurality of water-containing cavities 262. A water baffle 263 is arranged between adjacent partition plates 261. The water baffle 263 extends from a single partition plate 261 to another partition plate 261 to reduce the water inflow of the water-containing cavity 262. The extension distance of the water baffle 263 between adjacent partition plates 261 is less than that of the adjacent partition plates 261. The spacing between adjacent partitions 261, and the difference between them forms a water inlet. The water baffle 263 is composed 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 arranged in a flat plate shape. The bottom plate and the extension end are spaced apart to form a water outlet. The width of the water inlet formed by the spacing between the water baffle 263 and the partition 261 is significantly reduced compared to the water inlet width of the water-containing cavity 262. Therefore, when the water body initially enters the water inlet tank 25, it enters a certain water-containing cavity 262. The speed will be reduced, so that the water can flow from one water-containing cavity 262 to the next water-containing cavity 262, and then the water in the entire water inlet tank 25 will flow, avoiding the situation where the water directly flows into one water-containing cavity 262. However, in order to better increase the flow range of the water in the water inlet tank 25, a folding plate 264 is provided on the water inlet track of the water inlet. The folding plate 264 is installed on the side wall of the partition plate 261 in an inclined shape and changes the flow direction of the water entering from the water inlet. The folding plate 264 It includes an installation section and an extension section. The installation end is installed horizontally, and the extension end gradually increases in height from the starting point where it is connected to the installation end. The end position is smaller than the bottom surface of the baffle 263. When water enters the water-containing cavity 262, it will be blocked by the inflection plate 264, which will cause backflow of water, thereby further reducing the speed of water entry, slowing down the speed of water entering the water-containing cavity 262, and laying the foundation for subsequent water to pass through the current water-containing cavity 262 and flow to the next water-containing cavity 262. The water guide member 26 divides the water-containing inner cavity 262 formed by the partition plate 261, and subdivides the water inlet channel from the water inlet trough 25 to the inner sleeve 23 into a plurality of channels, wherein the baffle plate 263 and the inflection plate 264 installed in the water-containing inner cavity 262 both reduce the amount of water entering the water-containing inner cavity 262, thereby injecting water into the water inlet trough 25 from a single position, and the water body evenly generates annular flow and spreads throughout the entire water inlet trough 25, thereby increasing the water diversion 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 trough group 24 includes a flooding port 241, a water extension port 242 and a water drop port 243 opened on the side wall of the inner sleeve 23. The flooding port 241 and the water drop port 243 are arranged between adjacent water extension ports 242. The flooding port 241, the water extension port 242 and the water drop port 243 are connected to the water inlet trough 25 and the inner sleeve 23. The flooding port 241 is located at the upper end of the water extension port 242 and is inclined upward. The height of the notch at one end of the water inlet trough 25 is less than the height of the notch at one end of the inner sleeve 23 to slow down the water body along the water inlet 25. The spreading speed of the overflow port 241 into the inner sleeve 23 is increased, and an extension port 242 is provided between the downspout 243 and the overflow port 241. The downspout 243 and the overflow port 241 are mirror-imaged, and the height of the notch at one end of the water inlet is greater than the height of the notch at one end of the inner sleeve 23. The extension port 242 is opened horizontally, and the water body passing through the overflow port 241 will diffuse irrigation water to the soil above the overflow port 241. This diffusion is a flooding type, that is, it occurs when the root soil is saturated to prevent siltation due to excessive water.

[0042] In order to increase the completeness of the seedlings being separated from the inner sleeve 23 during the separation process, the present scheme provides a separation disk 27 for auxiliary separation, which includes a disk body 271 that separates from the inner sleeve 23 synchronously with the seedlings and a plurality of stripping blades 272 annularly installed on the disk body 271. The spacing between adjacent stripping blades 272 is greater than the width of the water trough group 24. The disk body 271 is placed in the placement groove, and the top of one stripping blade 272 is marked with a starting mark. The top of the inner sleeve 23 is marked with an indication mark. The stripping blade 272 at the overlapping point of the starting mark and the indication mark is misaligned with the water trough group 24. The stripping pieces 272 at the lower end of the placement groove are surrounded by a wrapping sleeve to prevent soil from leaking out of the gaps between the stripping pieces 272. The upper ends of several stripping pieces 272 are connected with connecting rings 273, which slide on the inner wall of the inner sleeve 23. The inner wall of the inner sleeve 23 is provided with an inner ring groove extending to the installation position of the connecting ring 273. The connecting ring 273 is clamped on the wall of the inner ring groove, and the inner ring groove extends to the top of the inner sleeve 23. The connection ring 273 is arranged at the upper end of the flooding port 241. When planting, the soil is piled up in the disc 271. Based on its diffusivity, the soil will extend from between the stripping pieces 272 to the inner wall of the inner sleeve 23 and adhere to it after watering. This is the source of resistance generated when detaching. When detaching is required, the operator places his hand on the bottom of the disc 271 and applies force to rotate the disc 271. The stripping pieces 272 will generate a certain cutting force at this time to cut the soil adhered to the side wall of the inner sleeve 23, and then push upward to cause the connection ring 273 to detach from the upper end of the inner sleeve 23. At this time, the seedlings wrapped in the soil can be completely taken out. Then, it is only necessary to take the seedlings out of the detachment disc 27. On the one hand, the connection structure of the stripping disc with the soil is smaller than that of the existing cultivation pot, and the degree of damage to the soil is less than the stripping damage of the existing cultivation pot. On the other hand, the detachment disc 27 can also be set as a plastic structure, and the economic value generated will also be less than that of the existing cultivation pot.
