Description

Technical Field

[0001] This utility model relates to the field of greenhouse equipment technology, specifically to an automatic ventilation and adjustment window device for a Chinese medicinal herb seedling greenhouse. Background Technology

[0002] The cultivation of Chinese medicinal herbs requires stringent environmental conditions, including temperature, humidity, and ventilation. Greenhouses, as modern seedling cultivation facilities, provide suitable growing spaces for medicinal herb seedlings through scientifically controlled internal environments. The ventilation system, a core component of the greenhouse, promotes air circulation and regulates temperature and humidity, which is crucial for improving the survival rate and quality of medicinal herb seedlings.

[0003] Utility model patent CN214117873U discloses a top-opening window gear structure suitable for intelligent greenhouses. This structure includes a ridge-shaped roof and a truss. The two ends of the truss are fixedly connected to the bottom surface of the ridge-shaped roof. Ventilation openings are provided on both sides of the ridge-shaped roof, and a ventilation window is provided above each opening. The inner side of each ventilation window is hinged to the top surface of the ridge-shaped roof. The bottom surface of the truss is fixedly connected to the top surface of a fixed plate. The front side of the fixed plate is connected to the rear of a turntable via a bearing. A motor is fixedly installed on the front of the turntable. Two rotating shafts are located in front of the fixed plate. The rear end of one shaft is fixed to the front end of the motor's output shaft, and the rear end of the other shaft is connected to the other side of the front of the fixed plate via a bearing. Compared with existing technologies, this device uses fewer electrical components, uses common parts, has low production costs, and is easy to maintain. Furthermore, this device can simultaneously open or close several ventilation windows on any side of the ridge-shaped roof, making it convenient to use.

[0004] The top-opening window gear structure applicable to intelligent greenhouses uses an electric actuator to control gear meshing. Under strong wind impact, the fit between the electric actuator and the gear is prone to deviation, causing the gear to fail to mesh accurately, which in turn affects the opening and closing control of the ventilation window. Once the wind force is too strong, this control method is difficult to maintain the stable state of the ventilation window, which may cause the ventilation window to open or close unexpectedly. In view of this, we propose an automatic ventilation regulating window device for Chinese medicinal herb seedling greenhouses. Utility Model Content

[0005] The purpose of this invention is to provide an automatic ventilation and adjustment window device for a greenhouse for cultivating Chinese medicinal herbs, 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:

[0007] An automatic ventilation and regulating window device for a Chinese medicinal herb seedling greenhouse includes a window frame with a rectangular frame structure. An inner window is fitted at the front end of the window frame, and opening and closing components for opening and closing the inner window are provided on both the left and right sides of the rear end face of the window frame.

[0008] The inner edge of the front end face of the window frame is provided with a groove for receiving the inner window, and several guide blocks are fixed at the inner edge of the rear end face of the window frame.

[0009] The rear end face of the inner window is fixed with several guide rods corresponding to the position of the guide block. The guide rods pass through the guide block and are slidably connected to the guide block. Several protrusions are fixed at the left and right edges of the rear end face of the inner window.

[0010] The opening and closing assembly includes an opening and closing motor fixed on the window frame and a long shaft mounted on the window frame and rotatably connected to the window frame. The opening and closing motor drives the long shaft to rotate. Several levers are fixed on the long shaft. The end of each lever is hinged to the end of the protrusion. The end of each lever is provided with a stop rod, which is slidably connected to the end of the protrusion.

[0011] Preferably, a pair of fixing seats are fixed at the left and right edges of the rear end face of the window frame, the long shaft is located between the two fixing seats, and the end of the long shaft is inserted into the fixing seat and rotatably connected to the fixing seat.

[0012] In this setup, the long shaft is stably supported and positioned by a fixed bracket, ensuring stability during rotation and providing a reliable foundation for the opening and closing transmission of the inner window.

[0013] Preferably, the inner window is fitted with transparent glass in the middle. When the rear end face of the inner window abuts against the bottom of the groove, the inner window closes the hollow middle part of the window frame.

[0014] In this design, the transparent glass not only meets the greenhouse's lighting requirements but also effectively seals the window frame when closed, providing insulation and wind protection. The fitting design between the groove and the inner window further enhances the sealing performance.

[0015] Preferably, the end of the protrusion is provided with a waist-shaped groove, and the push rod extends into the waist-shaped groove and moves along the waist-shaped groove;

[0016] In this design, the cooperation between the waist-shaped groove and the abutment rod allows the lever to rotate flexibly, driving the inner window frame to slide linearly, adapting to positional changes during the sliding process of the inner window frame, and ensuring smooth transmission.

[0017] Preferably, the end of the guide rod is provided with a limiting rod, the diameter of which is larger than the diameter of the guide rod. When the inner window causes the guide rod to move outward, the head end of the limiting rod can abut against the guide block.

[0018] In this setup, the limiting rod works in conjunction with the guide block to restrict the movement range of the inner window frame, preventing it from moving excessively and detaching from the window frame, thus ensuring the safe operation of the device.

[0019] Preferably, the end of the limiting rod is provided with a baffle, the outer side of the guide rod is sleeved with a spring, the first end of the spring abuts against the inner window, and the end of the spring abuts against the baffle;

[0020] In this design, the spring forms a buffer structure between the limit rod and the baffle, absorbing the impact force of the inner window sliding and providing pre-tension to ensure that the inner window fits tightly into the groove when closed, thus improving sealing and wind resistance.

[0021] Preferably, a worm is coaxially connected to the end of the output shaft of the start-stop motor, and a worm wheel is coaxially connected to the end of the long shaft, with the worm meshing with the worm wheel;

[0022] In this configuration, the meshing transmission of the worm gear achieves stable power transmission, and the self-locking characteristic prevents the long shaft from rotating in a non-driven state, ensuring the inner window is fixed in position and enhancing the device's wind resistance stability.

[0023] Preferably, an outer cover is provided on the front end face of the window frame. The outer cover is in the shape of a hollow protrusion and the middle of the outer cover is transparent. Several openings are provided on the outer surface of the outer cover, and a mesh is provided on the outer side of the openings.

[0024] In this setup, the outer shield guides the airflow, reducing the direct impact of strong winds on the inner window and enhancing stability when the window is open; the opening works in conjunction with the mesh to ensure ventilation while blocking debris and insects from entering, thus optimizing the greenhouse environment.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] The automatic ventilation window adjustment device in this Chinese medicinal herb seedling greenhouse utilizes a worm gear transmission mechanism. The worm gear's self-locking characteristic allows the ventilation window to automatically lock after adjustment to a designated position, preventing the inner window from moving or opening / closing unexpectedly due to strong winds. This enhances wind resistance. Simultaneously, the precise guidance of the guide rod and guide block, along with the buffer limit of the spring pre-tensioning structure, effectively limits the swaying amplitude of the inner window when open, reducing the direct impact of wind pressure on the device. Furthermore, the simplified transmission structure reduces easily loosened parts, lowering the risk of malfunctions caused by strong wind vibrations. This ensures stable and precise opening and closing control of the ventilation window even in severe weather, providing a stable greenhouse environment for Chinese medicinal herb seedling cultivation.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0041] Please see Figures 1-8An automatic ventilation and regulating window device for a Chinese medicinal herb seedling greenhouse includes a rectangular frame 100. An inner window 200 is fitted at the front end of the frame 100. Opening and closing components 300 for opening and closing the inner window 200 are provided on both the left and right sides of the rear end face of the frame 100. The rectangular frame 100 provides a stable frame for the entire device. The inner window 200 fits into the frame 100 to facilitate the opening and closing of the ventilation window. The opening and closing components 300 provide power and control for the opening and closing of the inner window 200.

[0042] like Figure 3 As shown in the figure, in this utility model, a groove 110 for receiving the inner window 200 is provided at the inner edge of the front end face of the window frame 100. A transparent glass is embedded in the middle of the inner window 200. When the rear end face of the inner window 200 abuts against the bottom of the groove 110, the inner window 200 closes the hollow middle part of the window frame 100. The groove 110 can receive the inner window 200, allowing it to fit tightly against the window frame 100 when closed, achieving a good sealing effect. The transparent glass allows light to pass through, meeting the greenhouse's lighting requirements, while simultaneously sealing the middle part of the window frame 100, providing insulation and wind protection.

[0043] like Figure 4 and Figure 5 As shown, specifically, several guide blocks 120 are fixed at the inner edge of the rear end face of the window frame 100, and several guide rods 220 corresponding to the positions of the guide blocks 120 are fixed at the rear end face of the inner window 200. The guide rods 220 pass through the guide blocks 120 and are slidably connected to the guide blocks 120. The cooperation between the guide blocks 120 and the guide rods 220 provides precise guidance for the sliding of the inner window 200, enabling the inner window 200 to open and close along the direction of the guide rods 220, ensuring that the inner window 200 runs smoothly during the opening and closing process and avoiding deviation or jamming.

[0044] like Figure 5 and Figure 6As shown, further, the end of the guide rod 220 is provided with a limiting rod 221. The diameter of the limiting rod 221 is larger than the diameter of the guide rod 220. When the inner window 200 drives the guide rod 220 to move outward, the head end of the limiting rod 221 can abut against the guide block 120. The limiting rod 221 can limit the movement range of the inner window 200 and prevent it from detaching from the window frame 100. The end of the limiting rod 221 is provided with a baffle 222, and the outer side of the guide rod 220 is fitted with a spring 230. The first end of the spring 230 abuts against the inner window 200, and the end of the spring 230 abuts against the baffle 222. The spring 230 plays a buffering role between the limiting rod 221 and the baffle 222, absorbing the impact force when the inner window 200 slides. At the same time, the spring 230 continuously provides pre-tight tension, and applies constant pressure to the inner window 200 inward through the guide rod 220, ensuring that the inner window 200 forms a tight surface contact seal when closed. This can effectively eliminate the assembly gap between the window frame 100 and the inner window 200, improve the sealing performance, effectively resist wind pressure penetration in strong wind environments, prevent backflow of external airflow, and maintain the stability of the internal environment of the greenhouse.

[0045] like Figure 4 and Figure 7 As shown, the opening and closing assembly 300 includes an opening and closing motor 310 fixed to the window frame 100 and a long shaft 320 mounted on and rotatably connected to the window frame 100. A pair of fixing seats 130 are fixed at the left and right edges of the rear end face of the window frame 100. The long shaft 320 is located between the two fixing seats 130, and its end is inserted into and rotatably connected to the fixing seat 130. A motor mount 140 for mounting the opening and closing motor 310 is fixed on the rear end face of the window frame 100. The output shaft of the opening and closing motor 310... A worm gear 311 is coaxially connected to the end of the long shaft 320, and a worm wheel 321 is coaxially connected to the end of the long shaft 320. The worm gear 311 and the worm wheel 321 mesh with each other. The opening and closing motor 310 serves as a power source. Through the meshing transmission of the worm gear 311 and the worm wheel 321, the power is transmitted to the long shaft 320, so that the opening and closing motor 310 can drive the long shaft 320 to rotate when working. At the same time, due to the self-locking characteristics of the worm gear and worm wheel, the long shaft 320 can be prevented from rotating on its own in the non-drive state, ensuring the fixed position of the inner window 200 and preventing the inner window 200 from being accidentally opened by strong winds.

[0046] like Figure 5As shown, it is worth noting that several protrusions 210 are fixed at the left and right edges of the rear end face of the inner window 200, and several levers 322 are fixed on the long shaft 320. The ends of the levers 322 are hinged to the ends of the protrusions 210, and the ends of the levers 322 are provided with a stop 323. The ends of the protrusions 210 are provided with a waist-shaped groove 211. The stop 323 extends into the waist-shaped groove 211 and moves along the waist-shaped groove 211, so that the ends of the levers 322 are restricted on the protrusions 210 while being able to slide along the direction of the waist-shaped groove 211. Through the hinge between the levers 322 and the protrusions 210 and the movement of the stop 323 in the waist-shaped groove 211, the rotation of the long shaft 320 is converted into the linear sliding of the inner window 200, realizing the smooth opening and closing of the inner window 200. At the same time, the waist-shaped groove 211 can adapt to the positional changes of the inner window 200 during the sliding process, ensuring the smoothness of the transmission.

[0047] like Figure 8 As shown, it is worth noting that an outer cover 400 is provided on the front surface of the window frame 100. The outer cover 400 is a hollow, protruding platform with a transparent center. This prevents the outer cover 400 from blocking light. When the inner window 200 is fully opened, the front surface of the inner window 200 abuts against the inner wall of the outer cover 400, providing a limiting support and enhancing the structural stability of the inner window 200 when fully open. Simultaneously, the outer cover 400 guides the airflow entering the greenhouse, preventing strong winds from directly impacting the inner window 200, reducing the impact of wind pressure on the device, and further improving wind resistance. Several openings 410 are provided on the outer surface of the outer cover 400. A mesh 420 is provided on the outer side of each opening 410. The openings 410, in conjunction with the mesh 420, ensure ventilation while preventing external debris and insects from entering, providing a good environment for the cultivation of medicinal herbs.

[0048] It is worth noting that the start-stop motor 310 involved in this utility model is a conventional technology and will not be described in detail here.

[0049] In this embodiment, the automatic ventilation and adjustment window device for the Chinese medicinal herb seedling greenhouse is used as follows: First, the opening and closing motor 310 is started to begin operation. At this time, the motor output shaft drives the worm gear 311 to rotate. The worm gear 311, through meshing with the worm wheel 321, drives the long shaft 320 to rotate. Then, the lever 322 on the long shaft 320 rotates accordingly. The abutment 323 at the end of the lever 322 slides in the waist-shaped groove 211 of the boss 210, converting the rotation of the long shaft 320 into the linear sliding of the inner window 200 along the direction of the guide rod 220. Next, under the guidance of the guide rod 220 and the guide block 120, the inner window 200 moves smoothly along the groove 110 to realize the opening or closing operation. During this process, the limiting rod 221 restricts the movement of the inner window 200. The system is designed to prevent the inner window 200 from opening or closing too much. Finally, once the required ventilation is achieved, the opening and closing motor 310 is shut off, and the long shaft 320 is locked in place using the self-locking characteristic of the worm gear, ensuring the stability of the inner window 200 and maintaining a suitable greenhouse environment. After the inner window 200 is opened, the tight cooperation between the guide rod 220 and the guide block 120 provides a stable guide for the inner window 200, effectively limiting its swaying amplitude under wind force. The self-locking mechanism of the worm gear prevents the inner window 200 from moving uncontrollably under wind force. The hollow boss structure of the outer baffle 400 guides the airflow, dispersing the impact of strong winds and preventing them from directly affecting the inner window 200. With the synergistic effect of multiple structures, the device maintains good wind resistance even when the window is open for ventilation.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
