An agricultural greenhouse is a facility used to protect crops from adverse weather conditions. It is usually a metal frame structure covered with plastic film or hard panels. It can provide a relatively stable microclimate environment, allowing crops to grow without seasonal restrictions, reducing the impact of pests and diseases, and can also cooperate with water-saving irrigation systems such as drip irrigation to achieve integrated water and fertilizer management and effectively save water and fertilizer.

[0048] Working principle: Use multiple greenhouse frames 1 to connect, set up the greenhouse, connect multiple sets of devices together to form greenhouse irrigation facilities, inject the prepared water and fertilizer liquid into the water and fertilizer tank 201, and complete the preparation work;

[0049] When drip irrigation is performed on the roots of crops, the electric push rod 701 is started, and the output end of the electric push rod 701 drives the connecting rod 702 to move, and the connecting rod 702 drives the rotating rod 703 to move, so that the rotating rod 703 drives the clamping gear 704 to slide in the inner gear ring 604, and the inner gear ring 604 and the clamping gear 704 are always meshed, and the rotating rod 703 drives the driving gear 705 to move until the driving gear 705 is meshed with the rotating gear 504, at which time the driving gear 705 is separated from the driven gear 902, the clamping block 1102 is inserted in the clamping groove 1101, and is in the initial clamping state, and the limiting cylinder 1004 blocks the spray hole 503;

[0050] The hydraulic lifting rod 303 is started, and the output end of the hydraulic lifting rod 303 drives the connecting plate 304 to move downward, so that the connecting plate 304 drives the connecting block 4 to move downward, so that the driving mechanism 6, the connecting assembly 7, the irrigation assembly 5, the adjusting assembly 8, the clamping assembly 11 and the limiting assembly 10 move downward until the drill bit 502 contacts the soil. At this time, the motor 602 is started, and the output shaft of the motor 602 rotates to drive the rotating drum 603 to rotate. Under the meshing action of the inner gear ring 604 and the clamping gear 704, the clamping gear 704 is forced to rotate, and the clamping gear 704 drives the rotating rod 703 to rotate, and the rotating rod 703 drives the driving gear 705 to rotate, and the driving gear 705 The rotation drives the rotating gear 504 to rotate, thereby causing the rotating tube 501 to rotate. Since the clamping block 1102 is inserted in the clamping slot 1101, when the rotating tube 501 rotates, the rotating ring 1002 rotates. The rotating ring 1002 rotates to drive the support rod 1003 to rotate, forcing the limiting cylinder 1004 to rotate, thereby causing the rotating tube 501, the drill bit 502, the limiting cylinder 1004 and the scraper 1005 to rotate synchronously. When the hydraulic lifting rod 303 continues to move downward, the drill bit 502 and the scraper 1005 rotate to break the soil, causing the limiting cylinder 1004 and the rotating tube 501 to move downward and penetrate into the soil until the spray hole 503 moves to align with the root position;

[0051] The liquid spray hole 503 is exposed, and the electric push rod 701 is started in reverse.

By controlling the solenoid valve 205, the pressure is reduced, so that the water and fertilizer liquid drips at the gap, and gradually drips the roots of the crops, thereby forming a drip irrigation function;

[0054] When the leaves of crops are sprinkled, the driving gear 705 is meshed with the driven gear 902, the driving gear 705 is separated from the rotating gear 504, the motor 602 is started in reverse, the output shaft of the motor 602 rotates to drive the rotating drum 603 to rotate, and the internal gear ring 604 and the clamping gear 704 mesh, forcing the clamping gear 704 to rotate, the clamping gear 704 drives the rotating rod 703 to rotate, the rotating rod 703 drives the driving gear 705 to rotate, the driving gear 705 rotates to drive the driven gear 902 to rotate, the driven gear 902 drives the transmission rod 901 to rotate, and the transmission rod 901 drives the transmission gear 90 3 rotates, forcing the transmission gear 2 904 to rotate, and the threaded rod 802 to rotate.

At this time, when the limiting cylinder 1004 moves downward, it drives the scraper 1005 to scrape the soil on the rotating tube 501;

[0055] The hydraulic lifting rod 303 is started in reverse, and the output end of the hydraulic lifting rod 303 drives the connecting plate 304 to move upward and backward, so that the connecting plate 304 drives the connecting block 4 to move upward, so that the driving mechanism 6, the connecting assembly 7, the irrigation assembly 5, the adjusting assembly 8, the clamping assembly 11 and the limiting assembly 10 move upward until the spray hole 503 is located at the spraying position of the leaf surface, and the motor 602 is started again to force the limiting cylinder 1004 to move upward, forcing the spray hole 503 to be exposed. When the limiting cylinder 1004 moves upward to the maximum limit, the spray hole 503 is completely exposed;

[0056] During sprinkler irrigation, the electric push rod 701 is started, forcing the driving gear 705 to mesh with the rotating gear 504, and the driving gear 705 is separated from the driven gear 902. The booster pump 203 and the solenoid valve 205 are started to force the water fertilizer liquid to be introduced into the rotating tube 501 and sprayed onto the leaf surface through the spray hole 503. At the same time, the motor 602 is started, and the output shaft of the motor 602 rotates to drive the rotating drum 603 to rotate. Under the meshing action of the inner gear ring 604 and the clamping gear 704, the clamping gear 704 is forced to rotate, and the clamping gear 704 drives the rotating rod 703 to rotate, and the rotating rod 703 drives the driving gear 705 to rotate. The driving gear 705 rotates and drives the rotating gear 504 to rotate, so that the rotating tube 501 rotates, and the rotating tube 501 drives the spray hole 503 to rotate. At the same time, the solenoid valve 205 is controlled to increase the pressure and expand the spraying range of the water fertilizer liquid, thereby forming the spraying function of the spray hole 503 on the leaf surface.

[0057] The setting of the liquid supply mechanism 2 can provide water and fertilizer liquid, provide pressure to the water and fertilizer liquid, and use the electromagnetic valve 205 to control the pressure, so as to realize the control of the flow rate of the liquid. During drip irrigation, the pressure is adjusted to a small value to form a drip irrigation effect, and during sprinkler irrigation, the pressure is increased to achieve the effect of sprinkler irrigation; the setting of the support mechanism 3 can realize the support effect of the connection block 4 and the components, improve the stability of the connection block 4, and can provide an ascending and descending force. When breaking the soil, the descending movement facilitates the drill bit 502 to break the soil. During sprinkler irrigation, the ascending movement can adjust the position of the spray hole 503, so as to realize sprinkler irrigation of crops at different heights; the setting of the irrigation component 5 can realize the conveying effect of the water and fertilizer liquid, so that the water and fertilizer liquid is discharged from the spray hole 503. The setting of the drill bit 502 can achieve the soil breaking effect, so that the spray hole 503 is located at the root, and the drip irrigation effect on the root is achieved; the setting of the driving mechanism 6 can provide power, on the one hand, it can force the irrigation component 5 to rotate, increase the spray range of the sprinkler irrigation, and at the same time, it can make the drill bit 502 rotate, so as to facilitate soil breaking and improve the soil breaking efficiency; on the other hand, it can realize the movement of the limiting component 10, so that the limiting cylinder 1004 can adjust the spray hole 503, so as to adjust the opening of the spray hole 503; the setting of the connecting component 7 can change the position of the driving gear 705, so that the driving mechanism 6 acts on the transmission component 9 or the irrigation component 5, so as to achieve multi-function and improve the flexibility of the device; The setting of the adjusting component 8 can realize the adjustment of the position of the limiting component 10, forcing the limiting component 10 to move up and down, and the setting of the threaded rod 802 can limit the position of the slider 803, thereby improving the stability of the slider 803, thereby realizing the clamping of the limiting cylinder 1004 and preventing the limiting cylinder 1004 from sliding freely; the setting of the transmission component 9 can achieve a transmission effect, so that the force of the driving mechanism 6 is transmitted to the transmission rod 901, forcing the transmission rod 901 to rotate, thereby transmitting the force to the adjusting component 8, realizing the adjustment of the limiting component 10, and improving the transmission capacity of the device; the setting of the limiting component 10 can realize the blocking and releasing of the spray hole 503. When the limiting cylinder 1004 and the spray hole 503 are completely When closed, liquid cannot flow out of the spray hole 503. When the limiting tube 1004 is not in contact with the spray hole 503, the spray opening of the spray hole 503 reaches the maximum. At the same time, the scraper 1005 can scrape the soil on the rotating tube 501 to avoid soil blocking the spray hole 503, thereby improving the rationality of the device. The setting of the clamping assembly 11 can realize the clamping of the rotating tube 501 and the limiting tube 1004, so that when breaking the soil, the rotating tube 501 and the limiting tube 1004 rotate synchronously to break the soil. The retreat of the limiting tube 1004 is used to form a gap between the soil and the rotating tube 501, which is convenient for drip irrigation of water and fertilizer liquid from the spray hole 503, avoiding the phenomenon that water and fertilizer liquid cannot flow out, thereby improving the practicality and rationality of the device.

[0058] This solution effectively combines root drip irrigation with foliar sprinkler irrigation of crops, realizes the switching function between drip irrigation mode and sprinkler irrigation mode, can provide necessary nutrients for crops, improve the adaptability of the device to the environment, greatly improves the efficiency of irrigation, is beneficial to the nutrient supply of crops, and is beneficial to the healthy growth of crops. Especially when facing large-scale crops, the automatic adjustment ability of the device is improved, and the staff can easily manage greenhouse crops, thereby reducing the cost of the enterprise.
