[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0017] The present utility model provides a carbon dioxide gas fertilizer slow-release device for a strawberry greenhouse, which includes a working chamber 1. An opening 101 is installed on the right side of the working chamber 1. A sealing plate 102 is hinged at the position of the opening 101. Soil 2 is installed at the bottom of the working chamber 1. Strawberries 201 are planted on the soil 2. A ventilation hole 3 is installed on the left side of the working chamber 1. A bracket 301 is fixedly connected to the outer wall of the working chamber 1 on the left side of the ventilation hole 3. A fan 302 is rotatably connected in the bracket 301. A motor 303 is fixedly connected to the bracket 301. A rotor 304 is rotatably connected in the motor 303. The rotor 304 is communicated with the fan 302. An auxiliary box 4 is installed on the top of the working chamber 1. The auxiliary box 4 is a hollow and open structure. A cover plate 401 is hinged at the open position of the auxiliary box 4. A partition plate 402 is fixedly connected in the auxiliary box 4. A plurality of supply pipes 403 are arranged between the auxiliary box 4 and the working chamber 1. Stop valves 404 are installed on the plurality of supply pipes 403. A crushing chamber 405 is formed between the partition plate 402 and the inner area of the auxiliary box 4. The cover plate 401 and the auxiliary box 4 are connected by fasteners 406. Small pieces of dry ice 407 are filled in the crushing chamber 405. A crushing roller 5 is rotatably connected in the crushing chamber 405. A motor 501 is installed on the outer wall of the auxiliary box 4. A rotating shaft 502 is rotatably connected in the motor 501. The rotating shaft 502 is communicated with the crushing roller 5. A carbon dioxide monitor penetrates through the working chamber 1.

[0018] When the carbon dioxide slow-release device for strawberry greenhouses is actually in use, the staff observes the carbon dioxide concentration in real time and makes an adaptive adjustment to the carbon dioxide concentration in the working chamber 1 according to the optimal concentration of carbon dioxide required for strawberry 201 production. When the concentration inside the working chamber 1 is too high, first, the cut-off valve 404 is in the closed state, and then the driving oil cylinder 602 drives the sliding rod 603 to cooperate with the connecting rod 604 to drive the baffle 601 to move upward, so that the ventilation hole 3 is in the open state. At this time, the motor 303 on the bracket 301 cooperates with the rotor 304 to drive the fan 302 to rotate, so that the carbon dioxide inside the working chamber 1 is discharged, and the value on the carbon dioxide monitor 503 is observed in real time. After discharging to the appropriate concentration, the oil cylinder 602 works again to drive the baffle 601 to reset, completing the closing work of the ventilation hole 3. When the carbon dioxide concentration inside the working chamber 1 needs to be increased, at this time, the ventilation hole 3 is in the closed state. The cover plate 401 is opened at the position of the auxiliary box 4, and small pieces of dry ice 407 are filled into the crushing chamber 405. Then, the fastener 406 is operated to fix and limit the cover plate 401 on the auxiliary box 4. Then, the motor 501 drives the rotating shaft 502 to drive the crushing roller 5 to finely crush the small pieces of dry ice 407, so that a large amount of carbon dioxide is generated in the crushing chamber 405. The carbon dioxide is transported to the position of the supply pipe 403 under the guidance of the channel 6. Then, the cut-off valve 404 is controlled to open, so that the carbon dioxide enters the working chamber 1. At the same time, the staff observes the value of the carbon dioxide monitor 503 in real time. After meeting the value, the cut-off valve 404 is closed. By setting the ventilation hole 3 structure on the side wall of the working chamber 1, and then installing a baffle structure that can slide up and down at the position of the ventilation hole 3 structure, the carbon dioxide is controlled to discharge from the outer wall of the working chamber 1. Then, a bracket 301 structure is installed at the position of the ventilation hole 3, and the fan 302 structure on the bracket 301 accelerates the discharge of carbon dioxide. When it is necessary to supply carbon dioxide to the inside of the working chamber 1, the dry ice in the crushing chamber 405 cooperates with multiple groups of supply pipes 403 and the cut-off valve 404 structure to complete the carbon dioxide supply work in the working chamber 1. Compared with the conventional complex carbon dioxide control device, the technical solution adopted by the present utility model can achieve high-efficiency and precise control of the carbon dioxide production concentration of strawberries 201 inside the working chamber 1, liberate the labor intensity of the staff, and the overall structure is compact, which is easy for the staff to install and maintain.

[0019] As Figure 1 shown, the partition plate 402 is evenly distributed with channels 6. A baffle 601 is installed on the right side of the ventilation hole 3. An oil cylinder 602 is installed on the top of the working chamber 1. A sliding rod 603 is slidably connected in the oil cylinder 602. The sliding rod 603 is connected to the baffle 601 through a connecting rod 604.

[0020] The effect achieved by the entire Embodiment 1 is that during use, the driving oil cylinder 602 drives the sliding rod 603 to cooperate with the connecting rod 604 to drive the baffle 601 to move upward, so that the ventilation hole 3 is in an open state, which is beneficial to the discharge of carbon dioxide in the working chamber 1.

[0021] Working principle: The staff observes the concentration of carbon dioxide in real time and makes an adaptive adjustment to the carbon dioxide concentration in the working chamber according to the optimal concentration of carbon dioxide required for strawberry production. When the concentration inside the working chamber is too high, first, the stop valve is in a closed state, and then the driving oil cylinder drives the sliding rod to cooperate with the connecting rod to drive the baffle to move upward, so that the ventilation hole is in an open state. At this time, the motor on the bracket cooperates with the rotor to drive the fan to rotate, so that the carbon dioxide inside the working chamber is discharged, and the value on the carbon dioxide monitor is observed in real time. After the carbon dioxide is discharged to an appropriate concentration, the oil cylinder works again to drive the baffle to reset, completing the closing work of the ventilation hole. When the carbon dioxide concentration inside the working chamber needs to be increased, the ventilation hole is in a closed state at this time. The cover plate is opened at the auxiliary tank position, and small pieces of dry ice are filled into the crushing chamber. Then, the fastener is operated to fix and limit the cover plate on the auxiliary tank. Then, the motor drives the rotating shaft to drive the crushing roller to refine and crush the small pieces of dry ice, so that a large amount of carbon dioxide is generated in the crushing chamber. The carbon dioxide is transported to the supply pipe position under the guidance of the channel. Then, the stop valve is controlled to open, so that the carbon dioxide enters the working chamber. At the same time, the staff observes the value of the carbon dioxide monitor in real time and closes the stop valve after the value is met.
