Description

Technical Field

[0001] This application relates to the technical field of forestry seedling cultivation, and more specifically, to an intelligent cultivation rack for forestry seedling cultivation. Background Art

[0002] In forestry planting, it is often necessary to artificially cultivate and raise seedlings of some precious plants, and then transplant them when the seedlings mature, so as to improve the planting survival rate. When raising seedlings, it is necessary to control the soil humidity to avoid water shortage affecting the growth or excessive waterlogging causing the seedlings to die of oxygen deficiency.

[0003] The prior art document with the publication number of CN220402561U provides an intelligent cultivation rack for forestry seedling cultivation, including a base. A control mechanism is arranged on the top of the base, and a cultivation mechanism is arranged inside the control mechanism. The control mechanism includes a cultivation box, a liquid level sensor is fixedly connected inside the cultivation box, a water tank is fixedly connected to the top of the base, a water pump is fixedly connected to the top of the base, and a controller is fixedly connected to the top of the base. For this intelligent cultivation rack for forestry seedling cultivation, under the connection of the connection holes, the liquid levels in each cultivation groove and the placement groove can be made the same. The liquid level sensor senses the liquid level height. When the liquid level height is lower than the set value, the liquid level sensor transmits the liquid level information to the controller, and the controller controls the water pump to start, filling the cultivation box with the culture solution in the water tank. When the liquid level height reaches the set value, the controller controls the water pump to stop working, and the purpose of automatic watering can be achieved.

[0004] Although the above prior art solutions can achieve relevant beneficial effects through the structures of the prior art, there are still the following defects:

[0005] 1. Once the liquid level is lower than the set height, the water pump stops, and once it reaches the set height, the water pump stops, which will cause the water pump to start and stop repeatedly, affecting the service life of the water pump;

[0006] 2. Directly controlling the liquid level height in the cultivation groove means that the roots of the plant seedlings are under the liquid level, affecting the respiration of the plant roots, and it is only suitable for some aquatic plants, and it is difficult for normal forestry seedlings to survive.

[0007] In view of the above-mentioned related technologies, the utility model inventors believe that once the liquid level is lower than the set height, the water pump stops, and once it reaches the set height, the water pump stops, which will cause the water pump to start and stop repeatedly, affecting the service life of the water pump. Directly controlling the liquid level height in the cultivation groove means that the roots of the plant seedlings are under the liquid level, affecting the respiration of the plant roots, and it is only suitable for some aquatic plants, and it is difficult for normal forestry seedlings to survive.

[0008] In view of this, we propose an intelligent cultivation rack for forestry seedling cultivation. Utility Model Content

[0009] 1. Technical Problems to be Solved

[0010] The purpose of this application is to provide an intelligent cultivation rack for forestry seedling raising, which solves the technical problems in the above background technology that once the liquid level is lower than the set height, the water pump stops, and once it reaches the set height, the water pump stops, which will cause the water pump to start and stop repeatedly, affecting the service life of the water pump. Directly controlling the liquid level height in the cultivation tank will cause the roots of plant seedlings to be submerged under the liquid level, affecting the respiration of plant roots, and only suitable for some aquatic plants, making it difficult for normal forestry seedlings to survive, and achieving the technical effect.

[0011] 2. Technical solution

[0012] The technical solution of this application provides an intelligent cultivation rack for forestry seedling raising, including:

[0013] Base;

[0014] Fixed box, the top of the base is provided with a fixed box through support legs;

[0015] Placement groove, a plurality of placement grooves are opened on the fixed box;

[0016] Support plate, a support plate is slidably clamped in the placement groove, and springs are installed between the two sides of the bottom of the support plate and the bottom of the placement groove;

[0017] Planting frame, a planting frame is movably placed on the support plate;

[0018] Water pump, a water pump is installed on the fixed box on one side of the placement groove;

[0019] Water tank, a water tank is installed on the base, and the water tank is connected to the water pump through a pipeline;

[0020] Opening and closing mechanism, an opening and closing mechanism is installed between the support plate and the bottom of the placement groove, and the opening and closing mechanism is electrically connected to the water pump.

[0021] Through the above scheme, soil is placed in the planting frame and forestry seedlings are planted. When the weight of the soil decreases due to the reduction of soil moisture to the lowest threshold, the spring pushes the support plate upward to open the water pump for watering. When the soil humidity increases and the weight increases, the support plate moves downward. When the water reaches the highest threshold, the opening and closing mechanism controls the water pump to stop, so that the water is kept within a certain range, avoiding repeated start and stop of the water pump, and the water is appropriate to meet the growth of seedlings and the respiration of roots.

[0022] Optionally, the inlet end of the water pump is connected to the water tank through a hose, the outlet end of the water pump is rotatably clamped with a U-shaped water outlet pipe, a water supply and drainage pipe is installed on the water tank, and a main switch is fixedly installed on the outer wall of the fixed box, and the main switch is electrically connected to the power supply and a plurality of opening and closing mechanisms.

[0023] Through the above solution, by rotatably installing the water outlet pipe, it is convenient to rotate the water outlet pipe away from the planting frame, facilitating planting and transplantation. The main switch is convenient for cutting off the power supply of all opening and closing mechanisms, making it convenient to cut off the power before planting and after transplantation.

[0024] Optionally, the opening and closing mechanism includes a fixed cylinder. The bottom of the inner cavity of the placement groove is fixedly installed with a fixed cylinder. A sliding rod is slidably clamped in the fixed cylinder. The top of the sliding rod is fixedly connected to the bottom surface of the support plate. A sliding frame is slidably clamped on the inner wall of the fixed cylinder. A push-pull rod is fixedly installed on the outer wall of the bottom of the sliding rod. The push-pull rod is slidably clamped in the inner cavity of the sliding frame. The top of the side wall of the fixed cylinder is fixedly embedded with a microswitch. The microswitch is located directly above the sliding frame. The microswitch is electrically connected to the water pump. The diameter of the push-pull rod is smaller than the inner cavity width of the sliding frame. A limiting groove is opened at the bottom of the inner wall of the fixed cylinder. A limiting block is fixedly installed at the bottom of the side wall of the sliding frame. The limiting block is slidably clamped in the limiting groove, and the cross-sections of the limiting block and the limiting groove are in a matching T-shaped structure. A rubber friction pad that fits the limiting groove is fixedly installed on the limiting block.

[0025] Through the above solution, when the soil moisture decreases, the weight in the planting frame decreases, and the spring pushes the support plate upward. At this time, the sliding rod moves upward, and the push-pull rod slides along the inner cavity of the sliding frame. When the push-pull rod moves to the top of the inner cavity of the sliding frame, it drives the sliding frame to move upward and touch the microswitch, causing the microswitch to close and the water pump to be powered on for watering. After watering, the soil moisture increases and the weight increases, and the support plate moves downward. At this time, the sliding rod drives the push-pull rod to move downward. The sliding frame will not automatically fall due to the friction of the limiting block. Then, the push-pull rod drives the sliding frame to move downward only after moving to the bottom of the inner cavity of the sliding frame, causing the microswitch to cut off the power, and watering stops. Then, watering is carried out for a period of time to keep the moisture between the maximum and minimum thresholds, meeting the growth of seedlings and avoiding frequent opening and closing of the water pump, prolonging the service life of the water pump.

[0026] Optionally, a connecting plate is fixedly sleeved at the bottom of the spring. A screw rod is fixedly installed at the bottom of the connecting plate. The screw rod is slidably clamped in the fixed box at the bottom of the placement groove. A guiding groove is opened on the screw rod. A guiding block that is clamped in the guiding groove is fixedly installed in the fixed box. A worm gear is slidably clamped in the fixed box. The worm gear is threadedly sleeved on the screw rod. A worm is rotatably sleeved in the fixed box. The worm meshes with the worm gear, and one end of the worm penetrates through the side wall of the fixed box and is fixedly installed with a knob.

[0027] Through the above solution, by rotating the worm, the worm gear is driven to rotate. The worm drives the screw rod to move through threading, thereby controlling the compression amount of the spring. The greater the compression amount, the higher the soil moisture content and weight required to continue moving the spring downward, facilitating the adjustment of the moisture threshold.

[0028] 3. Beneficial effects

[0029] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0030] 1. In this application, when the soil moisture decreases, the weight in the planting frame decreases, and the spring pushes the support plate upward. At this time, the sliding rod moves upward, and the push-pull rod slides along the inner cavity of the sliding frame. When the push-pull rod moves to the top of the inner cavity of the sliding frame, it drives the sliding frame upward to touch the microswitch, causing the microswitch to close and the water pump to be powered on for watering. After watering, the soil moisture increases and the weight increases, and the support plate moves downward. At this time, the sliding rod drives the push-pull rod downward. The sliding frame will not fall automatically due to the friction of the limiting block. Then, the push-pull rod drives the sliding frame downward only after moving to the bottom of the inner cavity of the sliding frame, causing the microswitch to lose power and stop watering. After watering for a period of time, the moisture is kept between the maximum and minimum thresholds, which meets the growth of seedlings and avoids frequent opening and closing of the water pump, prolonging the service life of the water pump;

[0031] 2. By rotating the worm, the worm gear is driven to rotate, and the worm thread drives the screw to move, thereby controlling the compression amount of the spring. The larger the compression amount, the higher the soil water content and weight required to continue moving the spring downward, which is convenient for adjusting the moisture threshold to meet different seedling cultivation.

Soil is placed in the planting frame 4 and forestry seedlings are planted. When the weight of the soil decreases due to the reduction of soil moisture to the lowest threshold, the spring 9 pushes the support plate 6 to move upward, so that the opening and closing mechanism 8 turns on the water pump 7 to water. When the soil humidity increases and the weight increases, the support plate 6 moves downward. When the moisture reaches the highest threshold, the opening and closing mechanism 8 controls the water pump 7 to stop, so that the moisture is maintained within a range, avoiding repeated start and stop of the water pump 7, and the moisture is appropriate, meeting the growth of seedlings and the respiration of roots.

[0040] Referring to Figure 1 、 Figure 2 and Figure 5 The inlet end of the water pump 7 is connected to the water tank 5 through a hose, the outlet end of the water pump 7 is rotatably clamped with a U-shaped water outlet pipe 71, a water supply and drainage pipe is installed on the water tank 5, the outer wall of the fixed box 2 is fixedly installed with a main switch 10, and the main switch 10 is electrically connected to the power supply and a plurality of opening and closing mechanisms 8. Through the rotatable installation of the water outlet pipe 71, it is convenient to rotate the water outlet pipe 71 away from the planting frame 4, facilitating planting and transplantation. The main switch 10 is convenient for powering off all the opening and closing mechanisms 8, facilitating power off before planting and after transplantation.

[0041] Referring to Figure 2 and Figure 3, the opening and closing mechanism 8 includes a fixed cylinder 81. The bottom of the inner cavity of the placement groove 3 is fixedly installed with the fixed cylinder 81. A sliding rod 82 is slidably clamped in the fixed cylinder 81. The top of the sliding rod 82 is fixedly connected to the bottom surface of the support plate 6. A sliding frame 83 is slidably clamped on the inner wall of the fixed cylinder 81. A push-pull rod 84 is fixedly installed on the outer wall of the bottom of the sliding rod 82. The push-pull rod 84 is slidably clamped in the inner cavity of the sliding frame 83. The top of the side wall of the fixed cylinder 81 is fixedly embedded with a micro switch 85. The micro switch 85 is located directly above the sliding frame 83. The micro switch 85 is electrically connected to the water pump 7. The diameter of the push-pull rod 84 is smaller than the inner cavity width of the sliding frame 83. A limiting groove 86 is opened at the bottom of the inner wall of the fixed cylinder 81. A limiting block 87 is fixedly installed on the bottom of the side wall of the sliding frame 83. The limiting block 87 is slidably clamped in the limiting groove 86. And the cross sections of the limiting block 87 and the limiting groove 86 are in a matching T-shaped structure. A rubber friction pad that fits the limiting groove 86 is fixedly installed on the limiting block 87. When the soil moisture decreases and the weight in the planting frame 4 decreases, the spring 9 pushes the support plate 6 upward. At this time, the sliding rod 82 moves upward, then the push-pull rod 84 slides along the inner cavity of the sliding frame 83. When the push-pull rod 84 moves to the top of the inner cavity of the sliding frame 83, it drives the sliding frame 83 to move upward and touch the micro switch 85, so that the micro switch 85 closes and the water pump 7 is powered on to water. After watering, the soil moisture increases and the weight increases, and the support plate 6 moves downward. At this time, the sliding rod 82 drives the push-pull rod 84 to move downward. The sliding frame 83 will not fall automatically due to the friction of the limiting block 87. Then the push-pull rod 84 drives the sliding frame 83 to move downward only after moving to the bottom of the inner cavity of the sliding frame 83, so that the micro switch 85 is powered off and the watering stops. Then water for a period of time to keep the moisture between the maximum and minimum thresholds, meet the growth of seedlings, and avoid frequent opening and closing of the water pump 7, prolonging the service life of the water pump 7.

[0042] Referring to Figure 2 and Figure 4 , a connecting plate 11 is fixedly sleeved at the bottom of the spring 9. A screw rod 12 is fixedly installed at the bottom of the connecting plate 11. The screw rod 12 is slidably clamped in the fixed box 2 at the bottom of the placement groove 3. A guiding groove 13 is opened on the screw rod 12. A guiding block 14 that is clamped in the guiding groove 13 is fixedly installed in the fixed box 2. A worm gear 15 is slidably clamped in the fixed box 2. The worm gear 15 is threadedly sleeved on the screw rod 12. A worm 16 is rotatably sleeved in the fixed box 2. The worm 16 meshes with the worm gear 15. And one end of the worm 16 penetrates through the side wall of the fixed box 2 and is fixedly installed with a knob. By rotating the worm 16, the worm gear 15 is driven to rotate. The worm 16 threadedly drives the screw rod 12 to move, thereby controlling the compression amount of the spring 9. The larger the compression amount, the higher the soil water content and the weight required to continue moving the spring 9 downward, which is convenient for adjusting the moisture threshold.

[0043] Working principle: When the soil moisture decreases, the weight inside the planting frame 4 reduces, and the spring 9 pushes the support plate 6 upward. At this time, the sliding rod 82 moves upward, and then the push-pull rod 84 slides along the inner cavity of the sliding frame 83. When the push-pull rod 84 moves to the top of the inner cavity of the sliding frame 83, it drives the sliding frame 83 to move upward and touch the microswitch 85, causing the microswitch 85 to close, then the water pump 7 is powered on for watering. After watering, the soil moisture increases and the weight increases, so the support plate 6 moves downward. At this time, the sliding rod 82 drives the push-pull rod 84 to move downward. The sliding frame 83 will not fall automatically due to the friction of the limit block 87. Then, when the push-pull rod 84 moves to the bottom of the inner cavity of the sliding frame 83, it drives the sliding frame 83 to move downward, causing the microswitch 85 to lose power, and then the watering stops. Watering is carried out for a period of time to keep the moisture between the maximum and minimum thresholds, which meets the growth of seedlings and avoids frequent opening and closing of the water pump 7, prolonging the service life of the water pump 7. By rotating the worm 16, the worm wheel 15 is driven to rotate. The worm 16 drives the screw rod 12 to move through the thread, thereby controlling the compression amount of the spring 9. The larger the compression amount, the higher the soil water content and weight required to continue moving the spring 9 downward, which is convenient for adjusting the moisture threshold to meet different seedling cultivation needs.
