Description

Technical Field

[0001] The invention relates to the technical field of agriculture, in particular to a carbon dioxide gas fertilizer machine for greenhouses. Background Art

[0002] With the rapid advancement of modern agriculture, greenhouse cultivation technology has become a key strategy for improving crop yield and quality. However, in this closed ecosystem, limited air circulation leads to carbon dioxide concentration becoming a core bottleneck restricting the efficiency of plant photosynthesis. Traditionally, farmers have relied on inefficient and costly methods such as natural ventilation or the artificial release of dry ice to replenish carbon dioxide. These methods are not only inefficient, but also cumbersome and costly.

[0003] Existing CO2 fertilizer dispensers, on the other hand, tend to be fixed in design, making it difficult to flexibly adapt to variations in CO2 concentrations across greenhouses and achieve precise delivery. Furthermore, these devices often require manual timed opening and closing, which increases farmers' workload and makes it difficult to ensure a consistently stable and even distribution of CO2 concentrations within the greenhouse.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a carbon dioxide gas fertilizer machine for greenhouses. Summary of the Invention

The main air supply pipe and the air box are connected by an air distribution pipe, and a plurality of groups of nozzles are installed in a side-by-side manner at the bottom of the air box.

[0007] As a preferred technical solution, multiple groups of reinforcement columns are installed between the transverse frames. The reinforcement columns are used to enhance the stability of the transverse frames to ensure the stability during the transverse movement. At the same time, they are used for the installation and fixation of the main air supply pipe.

[0008] As a preferred technical solution, air pipe interfaces are installed at both ends of the main air supply pipe, and the air pipe interfaces are used for connecting conveying hoses. Multiple components of air pipes are arranged at the bottom of the main air supply pipe.

[0011] As a preferred technical solution, a detachably connected mesh cover is provided at the bottom of the nozzle, and the mesh cover is used to disperse the carbon dioxide gas so that it can be evenly discharged.

[0015] This invention is a carbon dioxide fertilizer dispenser for greenhouses. A servo motor drives the main shaft, which in turn drives the main synchronous wheel, which in turn drives the secondary synchronous wheel and the entire moving mechanism via a synchronous belt, allowing the transverse frame to move smoothly left and right on the guide rails. This design not only enables flexible movement of the carbon dioxide delivery mechanism within the greenhouse, but also enables precise positioning and delivery based on the carbon dioxide concentration requirements of different areas within the greenhouse, greatly improving the utilization efficiency of carbon dioxide.

[0016] The present invention is a carbon dioxide fertilizer dispenser for greenhouses. During operation, gas from the carbon dioxide tank enters the pressure regulating valve through an air inlet solenoid valve. After precise regulation by the pressure regulating valve, it is delivered to the air box below the transverse frame via a delivery hose and a main air supply pipe. Partitions within the air box divide the air box into multiple air chambers, each of which is connected to the main air supply pipe via a gas distribution pipe, ensuring uniform gas distribution. Furthermore, the design of the gas guide seat further disperses and buffers the gas within the air chamber, reducing the potential impact of direct gas injection on plants.

[0017] This invention is a greenhouse carbon dioxide fertilizer dispenser with an intelligent monitoring and delivery component. Through a controller mounted on a column and multiple sensors distributed on the underside of the top beam, it enables real-time monitoring and control of greenhouse environmental parameters. When parameters such as carbon dioxide concentration, temperature, or humidity deviate from set ranges, the controller automatically triggers an alarm and adjusts the operating state of the air intake solenoid valve and servo motor to quickly restore the greenhouse to a suitable environment, reducing farmers' labor intensity and improving production efficiency.

[0018] The present invention can solve the problems of low efficiency, complicated operation and high cost in traditional methods, and provides strong support for greenhouse planting technology in modern agriculture. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0025] See also Figure 1-3As shown, the present invention provides a technical solution for a carbon dioxide fertilizer machine for a greenhouse: it includes multiple groups of columns 11 installed in the greenhouse, and a top beam 12 is commonly installed on the top surface of the columns 11 on the same side, and a tank seat 13 is installed on the outer wall of the column 11. The tank seat 13 is used to install a carbon dioxide gas cylinder 3, and the carbon dioxide gas cylinder 3 is fixed to the column 11 by a fixing strap 14. A moving mechanism is arranged between the top beams 12, and the moving mechanism includes a servo motor 21 installed on the top beam 12, and the output end of the servo motor 21 is connected to a main shaft 22. A main synchronous wheel seat 24 is installed on the two top beams 12, and the main shaft 22 is inserted into the main synchronous wheel seat 24. A main synchronous wheel 23 is mounted on the main shaft 22 located in the main synchronous wheel seat 24, and a secondary synchronous wheel seat 25 is provided on the opposite side of the main synchronous wheel seat 24. A secondary synchronous wheel 26 is installed on the secondary synchronous wheel seat 25, and a synchronous belt is connected between the main synchronous wheel 23 and the secondary synchronous wheel 26. 27 transmission connection, guide rails 61 are installed on the adjacent sides of the synchronous belt 27, and guide seats 62 are slidably connected to the guide rails 61. A transverse frame 29 is installed between the two sets of guide seats 62, and the transverse frame 29 is connected to the synchronous belt 27 by a synchronous belt clamp 28. An air intake solenoid valve 31 is provided on the top of the carbon dioxide gas tank 3, and the port of the air intake solenoid valve 31 is connected to a carbon dioxide delivery mechanism, which includes a pressure regulating valve 33 installed on the top beam 12, and the input end of the pressure regulating valve 33 is connected to the air intake solenoid valve 31 through a connecting air pipe 32, and the output end of the pressure regulating valve 33 is connected to a delivery hose 34, and the tail end of the delivery hose 34 is connected to a main air supply pipe 35, which is installed on the transverse frame 29, and an air box 36 is installed at the bottom of the transverse frame 29. The main air supply pipe 35 is connected to the air box 36 through a gas distribution pipe 351, and a plurality of groups of nozzles 4 are installed in a side-by-side manner at the bottom of the air box 36.

[0026] In this embodiment, the servo motor 21 is activated, and its output drives the main shaft 22 to rotate, which in turn drives the main synchronous pulley 23. Through the tight engagement of the timing belt 27, the secondary synchronous pulley 26 also rotates synchronously, achieving efficient power transmission between the two side beams 12. As the timing belt 27 circulates, the timing belt clamp 28 mounted on it drives the traverse frame 29 to smoothly move laterally along the guide rail 61. This design ensures that the CO2 dispensing mechanism can flexibly move within the greenhouse, covering a wider area.

[0027] When the traverse frame 29 moves to the designated position, the inlet solenoid valve 31 is controlled to open, allowing the gas in the carbon dioxide cylinder 3 to enter the pressure regulating valve 33 through the connecting air pipe 32. The pressure regulating valve 33 precisely controls the gas according to the preset pressure value, ensuring the output gas pressure is stable and suitable for plant growth. The regulated gas then enters the main gas supply pipe 35 through the delivery hose 34, and is ultimately diverted to the gas box 36 mounted at the bottom of the traverse frame 29.

[0028] The gas box 36 acts as a temporary gas storage and distribution center, injecting carbon dioxide evenly and densely into the air surrounding the plants through multiple sets of side-by-side nozzles 4. This design not only improves the utilization rate of carbon dioxide but also promotes the efficient absorption of gas by plant leaves, thereby accelerating the plant's photosynthesis process and helping to improve crop yield and quality.

[0029] Throughout the entire operation, precise control of the servo motor's speed and travel distance, as well as the pressure setting of the pressure regulating valve, allows for accurate regulation of the amount, speed, and area of ​​CO2 delivery. This intelligent greenhouse CO2 fertilization system not only improves agricultural production efficiency but also reduces manual intervention and fertilizer use, providing strong support for the sustainable development of modern agriculture.

[0030] See also Figure 1-3 As shown, multiple groups of reinforcement columns 291 are installed between the transverse frames 29. The reinforcement columns 291 are used to enhance the stability of the transverse frames 29 to ensure that during the transverse movement, they are also used to install and fix the main air supply pipe 35. Both ends of the main air supply pipe 35 are equipped with air pipe interfaces 352. The air pipe interfaces 352 are used to connect the delivery hose 34. Multiple groups of air pipes 351 are installed at the bottom of the main air supply pipe 35. Multiple groups of partitions 361 are installed in the air box 36, and several air cavities are separated. A box cover 38 is installed on the top of the air box 36, and multiple groups of air pipe sockets 38 are provided on the box cover 38. 1. The trachea socket 381 is connected to the air cavity and is used for inserting and assembling the air distribution pipe 351. An air guide seat 37 is installed in each air cavity. The outer wall of the air guide seat 37 is in close contact with the inner wall of the air cavity. The top of the air guide seat 37 is provided with a recess 371 with four sloped sides. The bottom of the recess 371 is provided with two groups of air holes 372. The top of the nozzle 4 is provided with an insertion end 41, which passes through the air box 36 and is assembled with the air holes 372. The bottom of the nozzle 4 is provided with a detachable mesh cover 42. The mesh cover 42 is used to disperse the carbon dioxide gas so that it is evenly discharged.

[0031] In this embodiment, the insertion end 41 of the air jet 4 is precisely machined to ensure a close fit with the air hole 372, minimizing gas leakage. Furthermore, the mesh cover 42 at the bottom of the air jet 4 is porous, effectively dispersing the carbon dioxide gas while preventing impurities from entering the air jet, ensuring smooth airflow.

[0032] See also Figure 1-3As shown, an intelligent monitoring and delivery component is also installed between the column 11 and the top beam 12. The intelligent monitoring and delivery component includes a controller 5 installed on the column 11. The bottom surface of the top beam 12 is evenly spaced and sequentially installed with a carbon dioxide concentration sensor 1 51, a carbon dioxide concentration sensor 2 52 and a carbon dioxide concentration sensor 3 53. A temperature sensor 54 and a humidity sensor 55 are respectively installed between adjacent ones. An alarm 56 is installed on the outer wall of the column 11. The carbon dioxide concentration sensor 1 51, the carbon dioxide concentration sensor 2 52, the carbon dioxide concentration sensor 3 53, the temperature sensor 54, the humidity sensor 55 and the alarm 56 are connected to the controller 5. The alarm 56 is controlled and connected to the intake solenoid valve 31 and the servo motor 21.

[0033] In this embodiment, the intelligent monitoring and delivery component can monitor the environmental parameters within the greenhouse in real time to ensure the accuracy and safety of carbon dioxide fertilization. Controller 5 serves as the hub of the entire system, responsible for receiving and processing data from various sensors. Carbon dioxide concentration sensor 1 51, carbon dioxide concentration sensor 2 52, and carbon dioxide concentration sensor 3 53 are located in different areas of the greenhouse. Through their coordinated operation, the distribution of carbon dioxide concentration in the greenhouse can be fully understood. If an abnormal concentration is detected, controller 5 will immediately initiate countermeasures.

[0034] Meanwhile, temperature sensor 54 and humidity sensor 55 monitor the temperature and humidity conditions within the greenhouse, both of which are crucial for plant growth. Their data helps controller 5 more accurately determine whether the current environment is suitable for plant growth, thereby adjusting the CO2 injection strategy.

[0035] When the greenhouse's CO2 concentration, temperature, or humidity exceed preset ranges, controller 5 triggers alarm 56 to alert staff. Simultaneously, controller 5 automatically adjusts the opening of air inlet solenoid valve 31 to control the amount of CO2 delivered, or adjusts the speed and direction of servo motor 21 to more precisely target the area requiring additional CO2 delivery.

[0036] This intelligent monitoring and deployment not only improves the stability of greenhouse environmental parameters but also significantly reduces the workload of greenhouse workers. They only need to regularly check equipment operation and adjust preset parameters as needed. Furthermore, it reduces fertilizer usage, lowers agricultural production costs, and contributes to the sustainable development of modern agriculture.

[0037] The working principle and usage process of the present invention: Controller 5 enters a standby state, waiting to receive data from CO2 concentration sensor 1 51, CO2 concentration sensor 2 52, CO2 concentration sensor 3 53, temperature sensor 54, and humidity sensor 55. At this time, servo motor 21 remains stationary, and the timing belt 27, its timing belt clamp 28, and traverse frame 29 are also in their initial positions.

[0038] When the greenhouse's CO2 concentration, temperature, or humidity falls below preset values, controller 5 analyzes the sensor data and issues commands to servo motor 21 and air inlet solenoid valve 31. Upon receiving these commands, servo motor 21 begins to drive synchronous belt 27 in a circular motion, moving transverse frame 29 smoothly along guide rail 61 toward the target area. Simultaneously, air inlet solenoid valve 31 opens, allowing gas from CO2 tank 3 to enter pressure regulating valve 33 through connecting air pipe 32 for pressure regulation.

[0039] The pressure-regulated gas enters the main air supply pipe 35 through a delivery hose 34 and is distributed to various air boxes 36. Within the air boxes 36, the gas passes through the notches 371 and air holes 372 of the air guide seat 37, and is ultimately evenly sprayed into the air surrounding the plants by the mesh cover 42 at the bottom of the air nozzle 4. The porous design of the mesh cover 42 not only ensures uniform gas distribution but also prevents impurities from entering the air nozzle.

[0040] During the release process, the intelligent monitoring and release component continuously monitors environmental parameters within the greenhouse. If the CO2 concentration, temperature, or humidity exceed preset ranges, the controller 5 will immediately respond. For example, if the CO2 concentration is too high, the controller 5 will reduce the opening of the air inlet solenoid valve 31, thereby reducing the amount of CO2 released. If the temperature or humidity is abnormal, other measures (such as activating ventilation equipment or a humidifier) ​​will be used to adjust the situation.

[0041] Once the traverse frame 29 reaches the designated position and completes the CO2 delivery, the servo motor 21 drives it back to its initial position or continues to the next target area for delivery. Throughout this process, the controller 5 intelligently controls the greenhouse environment and preset parameters to ensure accurate and efficient CO2 fertilization.

[0042] Furthermore, the greenhouse CO2 fertilization system of the present invention also features fault self-diagnosis and alarm functions. When an abnormality occurs in the system (e.g., sensor failure, motor failure, etc.), the controller 5 triggers the alarm 56 to sound an alarm, alerting personnel to conduct prompt inspection and repair.

[0043] This invention uses intelligent monitoring and delivery technology to precisely control greenhouse environmental parameters and efficiently manage carbon dioxide fertilization. This not only improves crop yield and quality, but also reduces agricultural production costs and labor intensity, providing strong support for the sustainable development of modern agriculture.
