Description

Technical Field

[0001] This utility model belongs to the field of corn planting technology, specifically relating to a seedling cultivation device for corn planting. Background Technology

[0002] Corn belongs to the Poaceae family and is an annual herbaceous plant. Corn seeds are large and round, and the most common color is yellow, but other colors also exist. With the emergence of more and more corn varieties, the cultivation process of different corn varieties is also different. Therefore, when choosing different corn varieties to plant, corn seedling cultivation devices can be used to experiment and determine the most suitable planting method for the early stage of corn seedlings.

[0003] For example, announcement number CN 222583130 U relates to a seedling cultivation device for corn planting. The device uses a placement box to effectively guide the liquid flowing out of the soil in the cultivation box to the water collection box below. The filter screen can effectively filter out impurities and mud in the liquid. The liquid then collects in the water collection chamber. The cultivator can open the drain valve at regular intervals to drain the liquid accumulated in the water collection chamber into the water collection bucket. The water in the water collection bucket can be recycled, effectively saving water resources and ensuring that the liquid does not drip onto the cultivation rack, thus preventing a large amount of water stains from remaining on the cultivation rack.

[0004] However, in actual use, the fixed position of the box makes the distance between the cultivation box and the photosynthetic lamp unadjustable, which makes it difficult to adapt to the different light intensity requirements of corn seedlings of different sizes. Therefore, this utility model provides a seedling cultivation device for corn planting. Summary of the Invention

[0005] The purpose of this invention is to provide a seedling cultivation device for corn planting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seedling cultivation device for corn planting, comprising a device frame, with fixed frames on both sides of the inner cavity of the device frame, a cultivation frame slidably connected between the two fixed frames, a placement groove opened inside the top of the cultivation frame, a plurality of equidistantly distributed cultivation boxes inside the placement groove, a photosynthesis lamp located directly above the cultivation boxes at the top of the inner cavity of the device frame, and a refraction plate rotatably connected to both sides of the photosynthesis lamp.

[0007] In a preferred embodiment, a drive motor is fixedly connected to the bottom of the fixing frame, and a drive screw is fixedly connected to the output shaft of the drive motor.

[0008] In a preferred embodiment, both sides of the cultivation rack are fixedly connected to a transmission frame threaded to the outside of the drive screw. The inner walls of both sides of the transmission frame are provided with guide protrusions, and both sides of the fixed frame are provided with guide grooves adapted to the guide protrusions.

[0009] In a preferred embodiment, a connecting plate is fixedly connected to the top of each transmission frame, and connecting rods are rotatably connected to both sides of the top of the connecting plate. The other end of each connecting rod is rotatably connected to one side of the movable end of the refraction plate, and the two connecting rods are arranged in a figure-eight shape.

[0010] In a preferred embodiment, each of the culture boxes has a culture tank inside, the bottom of the culture tank has a flow hole, both sides of the culture box have docking plates, and both sides of the culture rack have multiple docking slots that are adapted to the docking plates at equal intervals.

[0011] In a preferred embodiment, the docking plate has multiple arc-shaped limiting protrusions on the side facing the culture rack, and multiple limiting grooves adapted to the limiting protrusions are provided on the inner wall of the docking groove. A weakening groove is provided on the upper side of the docking plate facing the culture rack, and an auxiliary plate is provided on the outer side of the docking plate.

[0012] In a preferred embodiment, a filter box is fixedly connected to the bottom of the cultivation rack, and the bottom of the cultivation rack is fixedly connected to the filter box. A water collection tank is provided at the bottom of the inner cavity of the device frame, and the water collection tank and the filter box are fixedly connected by a hose.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This seedling cultivation device for corn planting uses a drive motor connected to a transmission frame via a drive screw to achieve smooth lifting and lowering of the cultivation frame. Compared to the fixed cultivation frame in the prior art, the lifting structure of this application can flexibly adjust the height of the cultivation frame. At the same time, the design of the guide protrusion and guide groove ensures the stability of the cultivation frame during the lifting process and avoids damage to the seedlings due to shaking.

[0015] This seedling cultivation device for corn planting uses rotatable refraction plates on both sides of the photosynthetic lamp and a linkage mechanism to link with the cultivation frame. When the cultivation frame is raised or lowered, the refraction plates automatically adjust their angles to optimize the light distribution. This design not only solves the problems of fixed photosynthetic lamp position and uneven light in the existing technology, but also allows for precise control of light intensity by adjusting the height of the cultivation frame through a drive motor according to the light intensity requirements of different corn varieties.

[0016] This seedling cultivation device for corn planting features a cultivation box that connects quickly to the cultivation frame via connecting plates on both sides. The interlocking design of the arc-shaped limiting protrusions and grooves ensures the stability of the cultivation box. Compared to the complex disassembly and assembly methods in existing technologies, this structure greatly simplifies the installation and disassembly process, reduces operational difficulty, and minimizes the risk of damage to seedlings during transfer. Furthermore, the weakening groove design on the connecting plates facilitates manual application of force, and the auxiliary plates further enhance operational convenience.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figure 1-4This utility model provides a seedling cultivation device for corn planting, including a device frame 1. The inner cavity of the device frame 1 is provided with fixed frames 2 on both sides. A cultivation frame 4 is slidably connected between the two fixed frames 2. A drive motor 5 is fixedly connected to the bottom of the fixed frame 2. A drive screw 3 is fixedly connected to the output shaft of the drive motor 5. A transmission frame 401 threaded to the outside of the drive screw 3 is fixedly connected to both sides of the cultivation frame 4. A guide protrusion 402 is provided on the inner wall of both sides of the transmission frame 401. A guide groove 201 adapted to the guide protrusion 402 is opened on both sides of the fixed frame 2.

[0025] When the height of the cultivation rack 4 needs to be adjusted, the drive motor 5 at the bottom of the fixed frame 2 is started. The output shaft of the drive motor 5 drives the drive screw 3 to rotate. The transmission frames 401 on both sides of the cultivation rack 4 are connected to the drive screw 3 by threads. When the drive screw 3 rotates, the transmission frame 401 moves along the axial direction of the drive screw 3. The guide protrusions 402 on both sides of the inner wall of the transmission frame 401 are embedded in the guide grooves 201 on both sides of the fixed frame 2 to form a sliding guide structure. Under the drive of the drive screw 3, the transmission frame 401 rises and falls smoothly along the guide grooves 201, driving the cultivation rack 4 to move synchronously. By controlling the forward and reverse rotation of the drive motor 5, the cultivation rack 4 can be raised or lowered, thereby adjusting the distance between the cultivation rack 4 and the photosynthesis lamp 101 at the top of the inner cavity of the device frame 1.

[0026] The light intensity requirement of corn seedlings changes with the growth stage. By adjusting the height of the cultivation rack 4, the vertical distance between the photosynthetic lamp 101 and the seedling can be changed, thereby precisely controlling the light intensity. The cooperative design of the guide protrusion 402 and the guide groove 201 converts the rotational motion of the transmission rack 401 into linear motion, while providing lateral support.

[0027] In this embodiment, a placement groove 405 is provided inside the top of the cultivation rack 4. Multiple cultivation boxes 6 are provided inside the placement groove 405 at equal intervals. Each cultivation box 6 has a cultivation groove 601 inside. A flow hole is provided at the bottom of the cultivation groove 601. A docking plate 602 is provided on both sides of the cultivation box 6. Multiple docking grooves 406 adapted to the docking plate 602 are provided at equal intervals on both sides of the cultivation rack 4. Multiple arc-shaped limiting protrusions 603 are provided on the side of the docking plate 602 facing the cultivation rack 4. Multiple limiting grooves 407 adapted to the limiting protrusions 603 are provided on the inner wall of the docking groove 406. A weakening groove 604 is provided above the side of the docking plate 602 facing the cultivation rack 4. An auxiliary plate 605 is provided on the outer side of the docking plate 602.

[0028] Align the connecting plates 602 on both sides of the cultivation box 6 with the connecting grooves 406 on the cultivation rack 4 and insert them horizontally. The arc-shaped limiting protrusions 603 on the connecting plates 602 engage with the limiting grooves 407 on the inner wall of the connecting grooves 406 to form a mechanical fixation. If the insertion resistance is too large, pressure can be applied through the weakening grooves 604 on the connecting plates 602 and the auxiliary plate 605 can be used to assist in pushing in. Apply a reverse force through the weakening grooves 604 or the auxiliary plate 605 to make the arc-shaped limiting protrusions 603 come out of the limiting grooves 407. Pull the cultivation box 6 horizontally out along the connecting grooves 406 to complete the disassembly. The roots of the corn seedlings grow in the cultivation trough 601, and excess water in the soil seeps out through the flow holes at the bottom of the cultivation trough 601.

[0029] The incubation box 6 is quickly fixed by the snap-fit ​​structure of the arc-shaped limiting protrusion 603 and the limiting groove 407. The design of the weakening groove 604 and the auxiliary plate 605 reduces the difficulty of disassembly. Multiple docking grooves 406 are equally spaced on both sides of the incubation rack 4, and the number and spacing of the incubation boxes 6 can be flexibly adjusted according to the needs. The multi-point snap-fit ​​of the arc-shaped limiting protrusion 603 and the limiting groove 407 forms a stable mechanical fixation. The weakening groove 604 on the docking plate 602 reduces the material strength by thinning the structure, making it easier to apply force manually.

[0030] In this embodiment, a photosynthesis lamp 101 is provided at the top of the inner cavity of the device frame 1, directly above the incubation box 6. A refraction plate 102 is rotatably connected to both sides of the photosynthesis lamp 101. A connecting plate 403 is fixedly connected to the top of each transmission frame 401. A connecting rod 404 is rotatably connected to both sides of the top of the connecting plate 403. The other end of each connecting rod 404 is rotatably connected to one side of the movable end of the refraction plate 102. The two connecting rods 404 are arranged in a figure-eight shape.

[0031] When the drive motor 5 starts, the drive screw 3 drives the transmission frame 401 to rise and fall. The connecting plate 403 at the top of the transmission frame 401 moves synchronously. The connecting rods 404 on both sides change angle due to the "V" shape layout. One end of the connecting rod 404 is rotatably connected to the connecting plate 403, and the other end is rotatably connected to the movable end of the refraction plate 102. When the connecting plate 403 rises, the connecting rod 404 pushes the refraction plate 102 to rotate inward. When the connecting plate 403 falls, the connecting rod 404 pulls the refraction plate 102 to rotate outward. The rotation angle of the refraction plate 102 is related to the height of the cultivation frame 4. When the refraction plate 102 is retracted, the light from the photosynthetic lamp 101 directly and vertically illuminates the cultivation box 6, which is suitable for corn seedlings that require strong light. When the refraction plate 102 is extended, the light diffuses after refraction, forming uniform diffused light, which is suitable for seedlings that require weak light or to avoid local overheating.

[0032] Through the linkage design of the connecting rod 404 and the refractive plate 102, the light intensity and distribution range of the photosynthesis lamp 101 are automatically adjusted with the height of the cultivation rack 4. The rotation of the refractive plate 102 does not occupy extra space and is automatically adjusted during the lifting and lowering of the cultivation rack 4 without manual intervention. When the refractive plate 102 extends outward, the light is diffused into diffuse reflection light, reducing the local light intensity. The rotation of the refractive plate 102 causes the light coverage range to change dynamically, eliminating the light dead angle in the inner cavity of the device frame 1.

[0033] In this embodiment, a filter box 7 is fixedly connected to the bottom of the cultivation rack 4, and the bottom of the cultivation rack 4 is fixedly connected to the filter box 7. A water collection tank 8 is provided at the bottom of the inner cavity of the device frame 1. The water collection tank 8 and the filter box 7 are fixedly connected through a hose. Water enters the filter box 7 through the flow hole for filtration and is then collected through the water collection tank 8.

[0034] It should be noted that the filter box 7 in the above scheme is the same as the filter equipment in the comparative document, so it is not described in detail.

[0035] The working principle and usage process of this utility model are as follows: First, align the docking plates 602 on both sides of the culture box 6 with the docking grooves 406 on the culture rack 4, and insert them horizontally. The arc-shaped limiting protrusions 603 on the docking plates 602 engage with the limiting grooves 407 on the inner wall of the docking grooves 406 to form a mechanical fixation. If the insertion resistance is large, pressure can be applied through the weakening grooves 604 on the docking plates 602, and the auxiliary plate 605 can be used to assist in pushing in. Applying a reverse force through the weakening grooves 604 or the auxiliary plate 605 will cause the arc-shaped limiting protrusions 603 to disengage from the limiting grooves 407. Then, the culture box 6 is inserted horizontally along the docking grooves 602. Pull out the groove 406 horizontally to complete disassembly. The roots of the corn seedlings grow in the cultivation trough 601. Excess water in the soil seeps out through the flow holes at the bottom of the cultivation trough 601. When it is necessary to adjust the height of the cultivation rack 4, start the drive motor 5 at the bottom of the fixed frame 2. The output shaft of the drive motor 5 drives the drive screw 3 to rotate. The transmission frames 401 on both sides of the cultivation rack 4 are connected to the drive screw 3 by threads. When the drive screw 3 rotates, the transmission frames 401 move along the axial direction of the drive screw 3. The guide protrusions 402 on both sides of the inner wall of the transmission frame 401 are embedded into the guide grooves 20 on both sides of the fixed frame 2. In section 1, a sliding guide structure is formed. Driven by the drive screw 3, the transmission frame 401 rises and falls smoothly along the guide groove 201, driving the cultivation rack 4 to move synchronously. By controlling the forward and reverse rotation of the drive motor 5, the cultivation rack 4 can be raised or lowered, thereby adjusting the distance between the cultivation rack 4 and the photosynthesis lamp 101 at the top of the inner cavity of the device frame 1. When the drive motor 5 starts, the drive screw 3 drives the transmission frame 401 to rise and fall, and the connecting plate 403 at the top of the transmission frame 401 moves synchronously. The connecting rods 404 on both sides change angle due to the "V"-shaped layout. One end of the connecting rod 404 is connected to the connecting plate 401. 3. Rotary connection, the other end is rotatably connected to the movable end of the refraction plate 102. When the connecting plate 403 rises, the connecting rod 404 pushes the refraction plate 102 to rotate inward; when the connecting plate 403 falls, the connecting rod 404 pulls the refraction plate 102 to rotate outward. The rotation angle of the refraction plate 102 is related to the height of the cultivation rack 4. When the refraction plate 102 is retracted, the light from the photosynthetic lamp 101 directly and vertically illuminates the cultivation box 6, which is suitable for corn seedlings that require strong light. When the refraction plate 102 is extended, the light diffuses after refraction, forming uniform diffuse reflection light, which is suitable for seedlings that require weak light or to avoid local overheating.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
