[0033] Reference Figures 1-10This application provides a sprinkler irrigation device for greenhouse cultivation. The sprinkler irrigation device for greenhouse cultivation may include a chassis 1, a water inlet pipe 2, a sprinkler irrigation mechanism, and a mixing mechanism. The water inlet pipe 2, the sprinkler irrigation mechanism, and the mixing mechanism are all mounted on the chassis 1. The water inlet pipe 2 connects the sprinkler irrigation mechanism to an external water source. The mixing mechanism may include a storage cylinder 3, a connecting pipe 4, a transfer component, a first valve 5, and a second valve 6. The storage cylinder 3 is located on one side of the chassis 1, with the end closest to the chassis 1 serving as the discharge port. The connecting pipe 4 is fixed to the side of the water inlet pipe 2 away from the chassis 1 and is connected to the water inlet pipe 2. The end of the connecting pipe 4 away from the water inlet pipe 2 serves as the feeding port. The transfer component is located on the side of the chassis 1 facing the storage cylinder 3 and between the storage cylinder 3 and the connecting pipe 4. The transfer component responds to the driving force of motion to quantitatively transfer the material at the discharge port to the feeding port. The first valve 5 is mounted on the connecting pipe 4. The second valve 6 is mounted on the connecting pipe 4 and is located between the first valve 5 and the feeding port.

[0034] This application discloses a sprinkler irrigation device for greenhouse cultivation. In the initial state, the first valve 5 is open and the second valve 6 is closed. When in use, fertilizer is added to the storage cylinder 3, and the fertilizer in the storage cylinder 3 is quantitatively transferred to the connecting pipe 4. At this time, the second valve 6 is closed first, and then the first valve 5 is opened. The fertilizer falls between the first valve 5 and the second valve 6. Then, the first valve 5 is closed first, and then the second valve 6 is opened. The fertilizer enters the water inlet pipe 2 and is transported to the sprinkler irrigation mechanism for sprinkler irrigation. During the process, fertilizer and water can be mixed simply by adding fertilizer to the storage cylinder 3. No prior operation is required, and the mixing operation and irrigation operation are carried out simultaneously, resulting in high work efficiency and convenient use.

[0035] Specifically, such as Figure 1 As shown, a walking wheel is provided on one side of the chassis 1. When moving the sprinkler device, the walking wheel can be placed on the ground.

[0036] It should be understood that there are many existing solutions for sprinkler irrigation systems, which will not be limited here. For example, such as Figure 1 As shown, a portion of the structure of a reel-type sprinkler is used as the sprinkler mechanism. The water inlet pipe 2 is connected to the water pipe on the reel. The reel is mounted on the chassis 1 and the water pipe on the reel is connected to the sprinkler head. The sprinkler head is detachably connected to the chassis 1 for mobile sprinkler irrigation.

[0037] At any given time, either the first valve 5 or the second valve 6 must be closed to prevent water from spraying out of the connecting pipe 4.

[0038] It should be understood that the flow rate of water inlet pipe 2 is fixed. The amount of fertilizer entering water inlet pipe 2 can be changed by adjusting the working efficiency of the transfer component, thereby further adjusting the fertilizer-to-water ratio.

[0039] Furthermore, the sprinkler irrigation device for greenhouse planting can also include multiple baffles. These baffles are spaced apart inside the water inlet pipe 2 and located between the connecting pipe 4 and the sprinkler irrigation mechanism. This way, when the water mixed with fertilizer flows through the baffles, the water and fertilizer will mix more evenly, resulting in better irrigation and preventing fertilizer from clogging the sprinkler irrigation mechanism.

[0040] refer to Figures 3-7 In an exemplary embodiment, the storage cylinder 3 and the connecting pipe 4 are spaced apart in a first direction, which is parallel to the plane of the chassis 1. The transfer assembly may include a moving rod 71, a drive unit, a transfer box 72, two first enclosed parts, and a second enclosed part. The moving rod 71 extends in a direction perpendicular to the second direction and has a degree of freedom to rotate about the second direction and a degree of freedom to move along the first direction. The second direction is parallel to the plane of the chassis 1 and perpendicular to the first direction. The drive unit is connected to the moving rod 71 and provides a driving force for the moving rod 71, so that one end of the moving rod 71 is in... The discharge port and the feeding port reciprocate; the transfer box 72 has an opening and is fixed to one end of the moving rod 71 that moves at the discharge port and the feeding port. When the transfer box 72 is at the discharge port, the opening faces the discharge port. When the transfer box 72 is at the feeding port, the opening faces the feeding port. Two first sealing parts are fixed at the discharge port and the feeding port respectively and respectively close the discharge port and the feeding port. The second sealing part is fixed at the opening and closes the opening. When the transfer box 72 is at the discharge port or the feeding port, the second sealing part cooperates with the corresponding first sealing part to open the opening and the discharge port or open the opening and the feeding port.

[0041] Specifically, such as Figure 7 As shown, the first direction is the X direction, and the second direction is the Y direction; as Figure 3 As shown, there is a gap between the storage cylinder 3 and the connecting pipe 4 in the thickness direction of the chassis 1, and the storage cylinder 3 is located on the side of the connecting pipe 4 away from the chassis 1.

[0042] The drive unit drives the moving rod 71 to move along the first direction X and rotate around the second direction Y, causing one end of the moving rod 71 to reciprocate between the discharge port and the feeding port, thereby driving the transfer box 72 to reciprocate between the discharge port and the feeding port. When the transfer box 72 moves to the discharge port, the opening faces the discharge port, and the second sealing part cooperates with the corresponding first sealing part to open the discharge port and the opening, so that the fertilizer in the storage cylinder 3 falls into the transfer box 72. When the transfer box 72 moves to the feeding port, the opening faces the feeding port, and the second sealing part cooperates with the corresponding first sealing part to open the feeding port and the opening, so that the fertilizer in the transfer box 72 falls into the connecting pipe 4 and finally enters the water inlet pipe 2, thus realizing the mixing of fertilizer and water.

[0043] refer to Figures 7-9In an exemplary embodiment, the transfer assembly may further include a first support plate 73, a second support plate 74, a first positioning pin 75, and a second positioning pin 76. The first support plate 73 has a first groove 731 extending along a first direction X; the second support plate 74 is spaced apart from the first support plate 73 in a second direction Y and has a second groove 741 extending along the first direction X. The center portion of the second groove 741 is recessed towards the chassis 1. A movable rod 71 is disposed between the first support plate 73 and the second support plate 74, and one end of the rod with the transfer box 72 extends out of the clamping space formed by the first support plate 73 and the second support plate 74. The first positioning pin 75 is rotatably connected to the side of the movable rod 71 facing the first support plate 73. The first positioning pin 75 passes through the first slide groove 731 and has a degree of freedom to slide along the extension path of the first slide groove 731. The first positioning pin 75 also has a degree of freedom to rotate about its own axis. The driving part is connected to the first positioning pin 75 and provides the first positioning pin 75 with a degree of freedom to move along the extension path of the first slide groove 731. The second positioning pin 76 is fixed to the side of the moving rod 71 facing the second support plate 74 and has the same axis as the second direction Y. The second positioning pin 76 passes through the second slide groove 741 and has a degree of freedom to slide along the extension path of the second slide groove 741. The second positioning pin 76 is disposed between the end of the moving rod 71 located in the first support plate 73 and the first positioning pin 75.

[0044] Specifically, such as Figure 7 As shown, the drive unit drives the first positioning pin 75 to move along the first slide groove 731. The first positioning pin 75 drives the moving rod 71 and the second positioning pin 76 to move. During the process, the second positioning pin 76 slides in the second slide groove 741, as shown. Figure 7 As shown, the recessed center of the second groove 741 towards the chassis 1 can be understood as the center of the second groove 741 being V-shaped. When the second positioning pin 76 passes one side of the V-shape, the first positioning pin 75 is still inside the first groove 731, and the second positioning pin 76 is located between the end of the moving rod 71 inside the first support plate 73 and the first positioning pin 75. At this time, the second positioning pin 76 will drive the moving rod 71 to rotate around the axial direction of the first positioning pin 75. When the second positioning pin 76 is at the bottom of the V-shape, the extension direction of the moving rod 71 is the same as the thickness direction of the chassis 1. When the second positioning pin 76 enters the other side of the V-shape, the moving rod 71 continues to rotate around the axial direction of the first positioning pin 75. When the second positioning pin 76 slides out of the V-shape, the extension direction of the moving rod 71 returns to the first direction X.

[0045] It should be understood that, taking the movement of the transfer box 72 from the discharge port to the feeding port as an example, the movement process of the moving rod 71 is divided into three stages; the first stage is the movement process before the second positioning pin 76 enters the V-shape, the moving rod 71 moves away from the discharge port along the first direction X, at this time the opening of the transfer box 72 faces away from the chassis 1; the second stage is the movement process when the second positioning pin 76 enters the V-shape, the moving rod 71 rotates and the rotation angle is 180°; the third stage is the process after the second positioning pin 76 leaves the V-shape, the moving rod 71 moves closer to the feeding port along the first direction X, at this time the opening of the transfer box 72 faces the chassis 1, thus realizing the transfer of fertilizer.

[0046] Furthermore, the minimum distance between the first slide groove 731 and the chassis 1 is a, the minimum distance between the second slide groove 741 and the chassis 1 is b, and the distance between the first positioning pin 75 and the second positioning pin 76 in the extension direction of the moving rod 71 is c, and ab=c; thus, when the second positioning pin 76 is at the bottom of the V-shape, the first positioning pin 75 is located directly above the second positioning pin 76 in the thickness direction of the chassis 1. At this time, the extension direction of the moving rod 71 is the same as the thickness direction of the chassis 1, ensuring that the moving rod 71 can rotate normally around the second direction Y.

[0047] It should be noted that the drive unit drives the first positioning pin 75 to slide back and forth in the first slide groove 731, which allows the transfer box 72 to move back and forth at the discharge port and the feeding port.

[0048] refer to Figures 7-9In an exemplary embodiment, the drive unit may include a connecting plate 771, a swing rod 772, a first slider 773, a connecting rod 774, a motor 775, and a second slider 776. The connecting plate 771 is fixed to the chassis 1 and located on the side of the first support plate 73 facing away from the second support plate 74. The swing rod 772 is rotatably connected to the side of the connecting plate 771 facing the first support plate 73. In the first direction X, the connection area between the swing rod 772 and the first support plate 73 is located at the center of the second slide groove 741. The swing rod 772 has a degree of freedom to swing about the second direction Y and its extension direction is perpendicular to the second direction Y. In the direction away from the connection area, the swing rod 772 is provided with a third slide groove 7711 and a fourth slide groove 7712 at intervals. The third slide groove 7711... The extension direction of the first slider 773 and the extension direction of the fourth slide groove 7712 are the same as the extension direction of the swing rod 772; the first slider 773 is slidably engaged with the third slide groove 7711 and has the freedom to slide along the extension direction of the third slide groove 7711; one end of the connecting rod 774 is rotatably connected to the first slider 773 and has the freedom to rotate around the second direction Y; the motor 775 is fixed on the connecting plate 771 and the output shaft axis is the same as the second direction Y, and the end of the connecting rod 774 away from the first slider 773 is fixed on the output shaft of the motor 775; the second slider 776 is slidably engaged with the fourth slide groove 7712 and has the freedom to slide along the extension direction of the fourth slide groove 7712, and the side of the second slider 776 facing the first support plate 73 is fixed to the first positioning pin 75.

[0049] Wherein, the length of the third slide groove 7711 in the thickness direction of the moving rod 71 is d, the length of the connecting rod 774 is e, and d > 2e; in the first direction X, the output shaft of the motor 775 is located at the center of the second slide groove 741; and when the extension direction of the swing rod 772 is the same as the thickness direction of the chassis 1, in the thickness direction of the chassis 1, the output shaft of the motor 775 is located near the center of the third slide groove 7711, ensuring that when the motor 775 drives the connecting rod 774 to rotate in one direction, the third slide groove 7711 can accommodate the sliding of the first slider 773, ensuring that the swing rod 772 can swing around the second direction Y.

[0050] Specifically, the output shaft of the motor 775 is located between the connection area of ​​the swing rod 772 and the first support plate 73 and the chassis 1. When the motor 775 is working, it drives the connecting rod 774 to rotate. The connecting rod 774 drives the first slider 773 to rotate around the output shaft of the motor 775. At the same time, the first slider 773 slides back and forth in the third slide groove 7711. The first slider 773 further drives the swing rod 772 to swing around the connection area of ​​the swing rod 772 and the connecting plate 771. During the process, the first slider 773 and the connecting rod 774... Relative rotation occurs between them; furthermore, when the swing rod 772 swings, it drives the second slider 776 to swing synchronously, and the second slider 776 can slide along the fourth slide groove 7712. Then the second slider 776 will drive the first positioning pin 75 to slide back and forth in the first slide groove 731. At the same time, the second slider 776 slides back and forth in the fourth slide groove 7712, and the first positioning pin 75 and the moving rod 71 rotate relative to each other. In this way, the first positioning pin 75 can be driven to move back and forth along the first slide groove 731 by the unidirectional rotation of the motor 775.

[0051] refer to Figures 5-10 In an exemplary embodiment, the first sealing portion connected to the storage cylinder 3 may include a first mounting plate 781, a first baffle 782, a first support block 783, a first spring 784, and a first limiting plate 785. The first mounting plate 781 is fixed to the outlet and has a through hole 7811 corresponding to the outlet. The first baffle 782 is slidably connected to the side of the first mounting plate 781 away from the storage cylinder 3 and has a degree of freedom to slide along the first direction X to close or open the through hole 7811. The first support block 783 is fixed to the side of the first mounting plate 781 away from the storage cylinder 3, wherein, in the first direction X, the first support block 783 is located on the side of the first baffle 782 away from the connecting pipe 4. The first spring 784 is connected between the first support block 783 and the first baffle 782 and extends along the first direction X. The first limiting plate 785 is fixed to the first baffle 782 away from the first mounting plate 781. The first limiting plate 785 is located on the moving path of the transfer box 72; the second closing part may include a second baffle 791, a second support block 792, a second spring 793, and a second limiting plate 794. The second baffle 791 is slidably connected to the moving rod 71 and has a degree of freedom to slide along the first direction X to close or open the opening; the second support block 792 is fixed to the side of the moving rod 71 facing the second baffle 791, wherein, in the extension direction of the moving rod 71, the second support block 792 is located on the side of the second baffle 791 away from the transfer box 72; the second spring 793 is connected between the second support block 792 and the second baffle 791 and extends in the same direction as the extension direction of the moving rod 71; the second limiting plate 794 is fixed to the side of the second baffle 791 away from the moving rod 71; wherein, the first mounting plate 781 is located on the moving path of the second limiting plate 794.

[0052] Specifically, when the moving rod 71 approaches the discharge port along the first direction X, the transfer box 72 moves synchronously. The transfer box 72 abuts against the first limiting plate 785 and pushes the first limiting plate 785 and the first baffle 782 to move along the first direction X to open the through hole 7811. The first mounting plate 781 abuts against the second limiting plate 794 and pushes the second limiting plate 794 and the second baffle 791 to move along the first direction X to open the opening. In this way, fertilizer can fall into the transfer box 72. When the moving rod 71 moves away from the discharge port along the first direction X, the first spring 784 pushes the first baffle 782 to move and close the discharge port. The second spring 793 pushes the second baffle 791 to move and close the opening. In this way, fertilizer can be transferred into the transfer box 72. When the transfer box 72 is at the connecting pipe 4, the working principle of the first sealing part and the second sealing part is similar to the above, and will not be described in detail here.

[0053] refer to Figure 4 and Figure 10 In an exemplary embodiment, the sprinkler irrigation device for greenhouse planting may further include a scraper 81, which is fixed to the side of the first mounting plate 781 away from the storage cylinder 3; wherein, when the transfer box 72 is located at the discharge port, the scraper 81 abuts against the second baffle 791.

[0054] Specifically, scraper 81 abuts against second baffle 791. When moving rod 71 moves away from the discharge port in the first direction X, scraper 81 can scrape off the fertilizer falling onto second baffle 791, so that the amount of fertilizer transferred to connecting pipe 4 by transfer box 72 is fixed each time, which makes it easier to control the mixing ratio of fertilizer and water.

[0055] refer to Figure 3 In an exemplary embodiment, the sprinkler irrigation device for greenhouse planting may further include a guide plate 82, which is fixed to the side of the first support plate 73 away from the connecting pipe 4 and located between the discharge port and the chassis 1. The side of the guide plate 82 away from the first support plate 73 is inclined toward the chassis 1.

[0056] It should be understood that the amount of fertilizer falling from the outlet should be greater than the capacity of the transfer box 72 to ensure that the transfer box 72 can be filled, making it easier to control the amount of fertilizer transferred each time.

[0057] Specifically, when the amount of fertilizer falling from the outlet exceeds the capacity of the transfer box 72, some of it will fall onto the guide plate 82. The guide plate 82 will collect the fertilizer for easy collection. At the same time, the fertilizer scraped off by the scraper 81 will also fall onto the guide plate 82 for collection.

[0058] refer to Figure 11 Based on the above embodiments, this application also provides a control method for a sprinkler irrigation device for greenhouse cultivation, including the aforementioned sprinkler irrigation device for greenhouse cultivation. This method is executed by a controller and may include the following steps:

[0059] S100, Obtain the current status of the first valve 5 and the second valve 6;

[0060] S200. If the first valve 5 is currently open and the second valve 6 is currently closed, then the first control signal and the second control signal are output to the first valve 5 and the second valve 6 in sequence according to a preset interval time. The first control signal is used to indicate that the first valve 5 is closed and the second control signal is used to indicate that the second valve 6 is open. The first control signal and the second control signal are spaced apart by a preset control time.

[0061] S300. If the first valve 5 is currently closed and the second valve 6 is currently open, then a third control signal and a fourth control signal are output to the second valve 6 and the first valve 5 respectively according to a preset interval time. The third control signal is used to indicate that the second valve 6 is closed, and the fourth control signal is used to indicate that the first valve 5 is open. The third control signal and the fourth control signal are spaced apart by a preset control time.

[0062] In step S100, the first valve 5 is initially in the open state, and the second valve 6 is initially in the closed state.

[0063] In step S200, after the transfer component transports the fertilizer to the connecting pipe 4, after a preset interval time, the controller outputs a first control signal to the first valve 5 and a second control signal to the second valve 6. The first control signal controls the first valve 5 to close, and the second control signal controls the second valve 6 to open. At this time, the fertilizer falls between the first valve 5 and the second valve 6.

[0064] In step S300, after the fertilizer falls between the first valve 5 and the second valve 6, after a preset interval, the controller outputs a third control signal to the second valve 6 and a fourth control signal to the first valve 5. The third control signal controls the second valve 6 to close, and the fourth control signal controls the first valve 5 to open. At this time, the fertilizer enters the water inlet pipe 2, and the transfer component will transfer the fertilizer to the connecting pipe 4 again. In this way, a cycle can be formed and the operation of fertilizer entering the water inlet pipe 2 can be continuously completed.

[0065] Furthermore, the preset interval time can be half the time it takes for the transfer component to complete one cycle of transfer; the interval between the first control signal and the second control signal is a preset control time, and the interval between the third control signal and the fourth control signal is a preset control time. This ensures that the valve in the open state is switched first each time. In other words, no matter when, one of the two valves will always be in the closed state, effectively preventing water from the inlet pipe 2 from spraying out from the connecting pipe 4. The preset control time should be greater than the time it takes for the valve to change from the open state to the closed state.

[0066] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
