Description

Technical Field

[0001] This utility model relates to the field of smart agriculture technology, specifically to a temperature and humidity control device for agricultural greenhouses. Background Technology

[0002] In modern agricultural production, agricultural greenhouses, as a controllable facility cultivation environment, can effectively overcome the limitations of natural climate, providing stable temperature and humidity conditions for crop growth, thereby improving crop yield and quality. They have become the core facility for the large-scale cultivation of cash crops such as vegetables, flowers, and seedlings. Temperature and humidity are key environmental factors affecting crop growth and development within greenhouses. Their precise regulation directly relates to the crop's photosynthetic efficiency, nutrient absorption capacity, and stress resistance. For example, excessively high temperatures can lead to excessive vegetative growth and the proliferation of pests and diseases, while excessively low temperatures can inhibit crop metabolism. Humidity imbalances can cause problems such as root rot and mold. Therefore, real-time adjustment and precise control of greenhouse temperature and humidity are core requirements for ensuring high yield and quality in facility agriculture.

[0003] In the prior art, such as the smart agricultural greenhouse temperature and humidity control device disclosed in application number 202420835744.4, the air inside the greenhouse is cooled and heated separately through a fan and a diversion pipe. Finally, the hot air and cold air are discharged through a hot air outlet hood and a cold air outlet hood. During the discharge process, a drive motor drives a threaded moving rod to rotate, which causes the sleeve to move left and right on the threaded moving rod, thereby moving the air inside the greenhouse to distribute the temperature more evenly, reducing the labor required and improving work efficiency.

[0004] However, in the application document published under application number 202420835744.4, the movement trajectory of the temperature and humidity control device is strictly constrained to a single horizontal straight line, making it impossible to adjust the angle during the forward and backward displacement process, let alone complete the attitude adjustment in the left and right directions. Furthermore, there are natural differences in the temperature and humidity distribution in different areas inside the greenhouse, making it difficult for the fixed-angle control device to accurately target and adjust to areas with abnormal temperature and humidity, resulting in insufficient control precision.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this invention is to provide a temperature and humidity control device for agricultural greenhouses to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides an agricultural greenhouse temperature and humidity control device, including a greenhouse body. A first motor is fixedly connected to one side of the top of the greenhouse body. A threaded rod is connected to the output end of the first motor. The end of the threaded rod away from the first motor is rotatably connected to the greenhouse body. A movable block is threadedly connected to the outer wall of the threaded rod. A mounting shell is fixedly connected to the bottom end of the movable block. A fixing plate is fixedly connected to the inner top wall of the mounting shell. A second motor is fixedly connected to the left side of the bottom end of the fixing plate. A first bracket is connected to the output end of the second motor. The first bracket is U-shaped. A worm gear is rotatably connected to the middle of the bottom end of the first bracket. A rotating column is fixedly connected to the middle of the worm gear. Both ends of the rotating column penetrate the outer wall of the first bracket. A second bracket is fixedly connected to the worm gear through both ends of the fixing column. A third motor is fixedly connected to the bottom end of the fixing plate away from the second motor. A worm is connected to the output end of the third motor. The worm is rotatably connected to the fixing plate.

[0008] Furthermore, a connecting shell is fixedly connected to the bottom of the second bracket. Two fixing components are installed on both sides of the inner wall of the connecting shell. Each fixing component includes a mounting block fixedly connected to the inner wall of the connecting shell. An electric push rod is fixedly connected to the top of the mounting block. A sliding block is connected to the telescopic end of the electric push rod. Multiple first connecting rods and multiple second connecting rods are rotatably connected to both sides of the outer wall of the sliding block. The multiple first connecting rods and multiple second connecting rods are arranged vertically and parallel. Claws are rotatably connected to both sides of the sliding block through the multiple first connecting rods and multiple second connecting rods. A guide groove is opened at the top of each claw. A fixing rod is slidably connected to the inner wall of the guide groove. The fixing rod is fixedly connected to the inner wall of the mounting block.

[0009] Furthermore, the worm gear meshes with the worm wheel, and the third motor drives the worm gear to rotate, thereby adjusting the angle of the worm wheel and the second support.

[0010] Furthermore, a fixing block is abutting and connected to one side of the two adjacent grippers. The outer wall of the fixing block has multiple slots, each slot being adapted to one end of the corresponding gripper. The bottom end of the fixing block is fixedly connected to the control device body.

[0011] Furthermore, the electric push rod extends and retracts, causing the sliding block to move. Through the first and second connecting rods, the two grippers slide along the guide groove and the fixed rod, thereby clamping and releasing the control device body.

[0012] Furthermore, the first motor drives the threaded rod to rotate, causing the moving block to move the mounting shell and the control device body horizontally back and forth along the length of the greenhouse.

[0013] Furthermore, the second motor can drive the first bracket to rotate, while the end of the first bracket away from the second motor does not contact the worm gear.

[0014] Furthermore, the inner wall of the slot is provided with an anti-slip pad layer to enhance the gripping stability of the gripper on the control device body and prevent it from falling off during fixation.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By adjusting multiple angles, the problem of incomplete temperature and humidity control coverage and insufficient detection and control accuracy caused by the fixed angle of traditional devices is solved. This avoids the situation where local temperature and humidity imbalance affects crop growth, reduces the problems of crop pests and diseases and uneven growth caused by blind spots in control, provides more stable environmental conditions for crop growth, and helps to improve crop yield and quality.

[0017] 2. The fixing block enhances the stability of the control device body through the interlocking connection of the slotted jaws, preventing loosening or falling off during movement. It also acts as a buffer to reduce the damage to the control device body caused by the clamping force, and facilitates installation and disassembly, improving maintenance efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution: an agricultural greenhouse temperature and humidity control device, including a greenhouse body 1. A first motor 2 is fixedly connected to one side of the top of the greenhouse body 1. A threaded rod 3 is connected to the output end of the first motor 2. The end of the threaded rod 3 away from the first motor 2 is rotatably connected to the greenhouse body 1. A movable block 4 is threadedly connected to the outer wall of the threaded rod 3. A mounting shell 5 is fixedly connected to the bottom end of the movable block 4. The first motor 2 drives the threaded rod 3 to rotate, causing the threaded movable block 4 to move linearly along the axial direction of the threaded rod 3, thereby driving the mounting shell 5 and internal components to move synchronously back and forth, achieving full longitudinal coverage of the greenhouse body 1. A fixing plate 6 is fixedly connected to the inner top wall of the mounting shell 5. A second motor 7 is fixedly connected to the left side of the bottom end of the fixing plate 6. A first bracket 8 is connected to the output end of the second motor 7. The first bracket 8 is U-shaped. A worm gear 9 is rotatably connected to the bottom center of the support 8. A rotating column is fixedly connected to the center of the worm gear 9. Both ends of the rotating column penetrate the outer wall of the first support 8. The worm gear 9 is fixedly connected to the second support 10 through the two ends of the fixed column. The second motor 7 drives the first support 8 to rotate around the output end, causing the worm gear 9, the second support 10 and subsequent connecting parts to rotate back and forth in the length direction of the greenhouse, adapting to different height or tilt angle operation requirements. A third motor 11 is fixedly connected to the bottom end of the fixed plate 6 on the side away from the second motor 7. The output end of the third motor 11 is connected to a worm 24. The worm 24 is rotatably connected to the fixed plate 6. The third motor 11 drives the worm 24 to rotate. Through the meshing transmission between the worm 24 and the worm gear 9, the worm gear 9 and the fixedly connected second support 10 are driven to rotate around the rotating column, realizing the left and right angle swing of the control component in the width direction of the greenhouse.

[0027] See Figure 5The bottom end of the second bracket 10 is fixedly connected to a connecting housing 12. Two fixing components are installed on both sides of the inner wall of the connecting housing 12. Each fixing component includes a mounting block 13 fixedly connected to the inner wall of the connecting housing 12. An electric push rod 14 is fixedly connected to the top of the mounting block 13. A sliding block 15 is connected to the telescopic end of the electric push rod 14. When the electric push rod 14 telescopically extends or retracts, it drives the sliding block 15 to move up and down vertically. Multiple first connecting rods 16 and multiple second connecting rods 17 are rotatably connected to both sides of the outer wall of the sliding block 15. The multiple first connecting rods 16 and multiple second connecting rods 17 are vertically connected. The sliding block 15 is arranged in parallel. Both sides of the sliding block 15 are rotatably connected to grippers 18 via multiple first connecting rods 16 and multiple second connecting rods 17. Each gripper 18 has a guide groove 19 at its top. A fixed rod 20 is slidably connected to the inner wall of the guide groove 19. The fixed rod 20 is fixedly connected to the inner wall of the mounting block 13. The sliding block 15 drives the grippers 18 on both sides to move via the multiple first connecting rods 16 and the second connecting rods 17. The guide groove 19 at the top of the gripper 18 slides along the fixed rod 20, so that the bottom of the gripper 18 makes horizontal opening and closing movements towards or away from each other, thereby clamping or releasing the load.

[0028] See Figure 5 Two grippers 18 are connected to a fixing block 21 on their adjacent sides. The outer wall of the fixing block 21 has multiple slots 22, each slot 22 being adapted to one end of the corresponding gripper 18. The bottom end of the fixing block 21 is fixedly connected to the control device body 23. The slots 22 on the outer wall of the fixing block 21 are adapted to one end of the gripper 18. When the gripper 18 is clamped, it is embedded in the slot 22, forming a mechanical limiting structure. This can effectively limit the relative displacement of the control device body 23 in the horizontal direction, ensuring that it always maintains a fixed position during overall movement and angle adjustment, avoiding displacement due to vibration or external force, and improving the accuracy of temperature and humidity detection and control.

[0029] See Figure 4 The worm gear 24 meshes with the worm wheel 9, and is driven to rotate by the third motor 11. This rotation drives the worm wheel 9 and the second bracket 10 to adjust their angles. The worm gear 24 can drive the worm wheel 9 to rotate, and vice versa. This allows the control device body 23 to maintain its stable posture after being adjusted to the target angle without the need for an additional locking structure, preventing angle deviations caused by airflow, vibration, or the device's own weight, and ensuring the stability of detection and control.

[0030] See Figure 2 The first motor 2 drives the threaded rod 3 to rotate, causing the moving block 4 to move the mounting shell 5 and the control device body 23 horizontally back and forth along the length of the greenhouse. The first motor 2 drives the threaded rod 3 to move the control device body 23 horizontally back and forth along the length of the greenhouse body 1, which can achieve full coverage from one end of the greenhouse body 1 to the other.

[0031] Working principle: The first motor 2 drives the threaded rod 3 to rotate, which in turn drives the threaded moving block 4 and the mounting shell 5 to move horizontally back and forth along the length of the greenhouse body 1, so as to achieve full longitudinal coverage;

[0032] The second motor 7 drives the U-shaped first support 8 to rotate, which in turn drives the worm wheel 9, the second support 10 and subsequent components to rotate back and forth along the length of the greenhouse. The third motor 11 drives the worm 24 to rotate, and through the meshing transmission of the worm 24 and the worm wheel 9, the second support 10 swings left and right along the width of the greenhouse. The worm 24 and the worm wheel 9 have self-locking properties to ensure angle stability.

[0033] The electric push rod 14 inside the outer shell 12 extends and retracts, causing the sliding block 15 to move up and down. Through the first connecting rod 16 and the second connecting rod 17, the gripper 18 is driven to slide along the fixed rod 20 and make horizontal opening and closing movements. The gripper 18 is embedded in the slot 22 of the fixed block 21 to clamp and fix the control device body 23. All structures work together to realize the three-dimensional movement and stable fixation of the control device body 23, accurately completing the detection and control of temperature and humidity throughout the greenhouse.

[0034] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
