Description

Technical Field

[0001] The invention relates to an automatic irrigation device, in particular to an automatic irrigation device for artificial forests in high-cold areas and an irrigation method thereof, which are applied to the technical field of automatic irrigation of artificial forests. Background Art

[0002] In high-altitude cold areas, due to low temperature and slow evaporation of soil moisture, but short plant growth period, it is necessary to regularly replenish the moisture of artificial forest soil to promote the normal growth of trees. The traditional irrigation method is to dig ditches and then irrigate the forest area with water, and the water penetrates into the soil. However, this irrigation method is time-consuming and labor-intensive, requiring the digging of more canals and a large amount of artificial drainage. The irrigation water cannot be fully utilized, resulting in a waste of water resources. Therefore, self-propelled irrigation equipment is used to replenish the moisture of artificial forest soil to save labor.

[0003] The invention patent with the publication number CN108207581A discloses a light and simplified intelligent self-propelled translational cantilever sprinkler, including a suspension and a traveling frame hinged at the top and bottom, a reset mechanism is arranged between the suspension and the traveling frame; the two sides of the suspension are symmetrically provided with a nozzle assembly, and the top of the suspension is provided with a wire rope assembly; two traveling wheel assemblies are symmetrically provided on both sides of the bottom of the traveling frame, and a water suction pipe assembly is arranged on the traveling frame between the two traveling wheel assemblies; the traveling frame is also provided with a power water pump assembly that provides power for the water suction pipe assembly and delivers the sucked water to the nozzle assembly, and a control box for controlling the operating status of the power water pump assembly and the traveling wheel assembly. This technical solution pumps up the water in the ditch through the cooperation of the water suction pipe assembly and the power water pump assembly, and completes the irrigation operation through the nozzle assembly, which greatly reduces energy consumption and improves irrigation efficiency.

[0004] When the above scheme is implemented, it is necessary to pre-dig an open canal in the irrigation area. For artificial forests in high-altitude areas with fewer people and larger areas, the initial canal laying cost is high and the operation is difficult. In addition, it is easy for debris to fall into the open canal, causing the suction pipe assembly to be blocked, requiring frequent manual maintenance. The equipment is driven horizontally by the walking wheel assembly. Since the equipment moves horizontally, it is necessary to constantly locate and correct its walking trajectory, which makes management more cumbersome. Summary of the invention

[0037] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0038] The first implementation method:

[0039] Figure 1-Figure 9 The automatic irrigation device for artificial forests in high-cold areas shown in the figure includes a fixed water source 1, a tracking supplementary pipe 9, a land contour plate 7, a contour tracking mechanism 8, a pressurized water pipe 18 and an irrigation intelligent controller. The fixed water source 1 is a well dug in the center of the land or an irrigation water pipe pre-buried in the center of the land. The water source position is fixed, and the laying cost is lower than that of traditional canal water sources. A pumping component 2 is installed at the fixed water source 1. The output end of the pumping component 2 is rotatably connected to a rotating pipe 3. The top of the rotating pipe 3 is connected to a delivery pipe 4. The pumping component 2 automatically pumps water from the fixed water source 1. The water flows out and is transported to the delivery pipe 4 through the rotating pipe 3. The rotating pipe 3 can rotate around the output end of the pumping component 2 during the water transportation process. The delivery pipe 4 is evenly connected with a plurality of irrigation nozzles 5 along its axial direction. A self-propelled wheel component 6 is installed on the delivery pipe 4. The self-propelled wheel component 6 drives the delivery pipe 4 and the rotating pipe 3 to perform circular motion with the pumping component 2 as the center. The delivery pipe 4 performs circular motion around the pumping component 2. The motion method is relatively simple and convenient. The irrigation water is irrigated through the irrigation nozzles 5 to irrigate the land swept by the delivery pipe 4 during the swinging process, thereby improving the irrigation efficiency.

[0040] The pumping assembly 2 is an automatic pumping device used to pump water to a designated pipe. The self-propelled wheel assembly 6 is a powered roller that can be driven by a driving motor to roll on its own. It is a common device in the field and is a prior art well known to personnel in the field. It is not within the scope of protection of this application, and this application will not go into details about its specific structure and working principle.

[0041] It is worth mentioning that the tracking supplementary pipe 9 is evenly connected with a plurality of tracking nozzles 10 along its axial direction. The tracking supplementary pipe 9 is arranged on the side of the delivery pipe 4 away from the end of the rotating pipe 3. The tracking supplementary pipe 9 is slidably connected with the delivery pipe 4 along the axial direction of the delivery pipe 4 through a slider 12. A driving component is installed on the slider 12. Since the land is mostly square structure or irregular shape, the coverage area of ​​the circular motion delivery pipe 4 in the square land is smaller than the area of ​​the square land, and more land that cannot be fully irrigated will be left at the four corners of the square land. By setting the tracking supplementary pipe 9, the tracking supplementary pipe 9 is installed on one side of the delivery pipe 4 as an extension pipe. The driving component controls the slider 12 and the tracking supplementary pipe 9 to extend forward, so that the irrigation range can be extended. When the front end of the tracking supplementary pipe 9 moves to the corner of the land, the tracking supplementary pipe 9 is controlled to move forward, so as to increase the irrigation range. The inner cavity of the tracking supplementary pipe 9 is slidably connected to the piston plate 28 with a hole in the middle. The delivery pipe 4 is connected to the middle hole of the piston plate 28 through the guide water pipe 11. The irrigation water enters the guide water pipe 11 through the delivery pipe 4 and enters the hole of the piston plate 28 through the guide water pipe 11. When the tracking supplementary pipe 9 is controlled to extend forward, the irrigation water enters the front end of the inner cavity of the tracking supplementary pipe 9, and as the tracking supplementary pipe 9 drives multiple tracking nozzles 10 to gradually extend forward, the water gradually enters the tracking nozzles 10 whose forward movement exceeds the piston plate 28, and the land at the corners is irrigated auxiliaryly through the tracking nozzles 10, thereby increasing the coverage area of ​​the irrigation device.

[0042] Also, see Figure 1 and Figure 7 The land contour plate 7 is connected to the pumping assembly 2, and the contour tracking mechanism 8 includes a mounting rod 22 fixed to the rotating tube 3, a pneumatic cylinder 23 installed on the mounting rod 22, and a tracking wheel 27 rolling along the outer ring of the land contour plate 7. The tracking wheel 27 is connected to the plug rod 24 plugged into the pneumatic cylinder 23 through a rotating shaft. The inner cavity of the pneumatic cylinder 23 is installed with a pressure sensor 31. The size of the land contour plate 7 is proportional to the size of the irrigated land, and the land contour plate 7 is placed in the same orientation as the land. When the conveying pipe 4 and the rotating pipe 3 move in a circle around the pumping assembly 2, the mounting rod 22 and the pneumatic cylinder 2 are driven. 3, and synchronously drives the tracking wheel 27 to roll along the outer circle track of the land contour plate 7. In the process of the tracking wheel 27 gradually moving along the outer periphery of the land contour plate 7, in the process of moving to the corner of the land contour plate 7 (i.e. the corner corresponding to the land), the tracking wheel 27 will drive the insertion rod 24 to compress the inner cavity gas of the air pressure cylinder 23, thereby increasing the inner cavity gas pressure of the air pressure cylinder 23. By judging the inner cavity gas pressure data of the air pressure cylinder 23, it can be judged that the corresponding delivery pipe 4 moves to the corresponding position of the land, and synchronously controls the tracking supplementary pipe 9 to extend the corresponding distance, so as to perform auxiliary irrigation on the corners of the land and improve the coverage rate of the irrigation device.

[0043] In this embodiment, the boosting water pipe 18 is connected to the end of the delivery pipe 4 away from the rotating tube 3, and a boosting pump 21 is installed on the boosting water pipe 18. Since the water pumping amount of the pumping component 2 is usually constant, when the tracking supplementary pipe 9 is extended, in order to avoid the gradual decrease in water pressure, the boosting pump 21 can be used to inject the water in the boosting water pipe 18 into the delivery pipe 4 to balance the water pressure in the delivery pipe 4 and make the irrigation more uniform.

[0044] The irrigation intelligent controller is arranged on one side of the pumping component 2. The irrigation intelligent controller is provided with a tracking module, a processing module, a tracking extension module and an auxiliary module. The processing module is electrically connected to the tracking module, the tracking extension module, the auxiliary module, the pumping component 2 and the self-propelled wheel component 6 respectively. The tracking module is electrically connected to the air pressure sensor 31, the tracking extension module is electrically connected to the driving component, and the auxiliary module is electrically connected to the booster pump 21. When irrigating the land, a land contour plate 7 that is proportional to the land is installed on the pumping component 2, and The tracking wheel 27 is placed on the side of the land contour plate 7, the processing module controls the pumping assembly 2 and the self-propelled wheel assembly 6 to work, the delivery pipe 4 and the rotating pipe 3 make a circular motion with the pumping assembly 2 as the center, and the tracking wheel 27 rolls along the track of the outer contour of the land contour plate 7. When the delivery pipe 4 gradually moves toward the corner of the land, the tracking wheel 27 also moves toward the corner of the land contour plate 7 synchronously. At this time, the tracking wheel 27 is pushed to drive the insertion rod 24 to be inserted into the inner cavity of the air pressure cylinder 23, and the air pressure sensor 31 detects the inner cavity of the air pressure cylinder 23. The air pressure increases, and the tracking module receives the air pressure data sent by the air pressure sensor 31 and sends it to the processing module. The processing module calculates the required extension amount of the tracking supplementary pipe 9 according to the increase in air pressure, to ensure that the tracking nozzle 10 on the tracking supplementary pipe 9 can cover the edge of the land. At this time, the processing module sends a control signal to the tracking extension module, and the tracking extension module controls the operation of the driving component, and the driving component pushes the slider 12 and the tracking supplementary pipe 9 to extend to the corresponding length. At the same time, the processing module sends a boost signal to the auxiliary module, and the auxiliary module controls the boosting pump 21 to work and fill the water in the boosting water pipe 18 into the delivery pipe 4, thereby simultaneously increasing the water pressure in the delivery pipe 4 and the tracking supplementary pipe 9, and reducing the problem of uneven irrigation caused by the decrease in water pressure in the delivery pipe 4. The delivery pipe 4 and the tracking supplementary pipe 9 are driven in a circular motion by the self-propelled wheel assembly 6, so that the land is irrigated conveniently and quickly, and during the irrigation process, the extension distance of the tracking supplementary pipe 9 is controlled according to the shape of different plots, thereby increasing the coverage area of ​​the circular motion irrigation device, improving the irrigation efficiency and irrigation effect.

[0045] In this embodiment, the driving assembly includes a driving member 13 installed with the conveying pipe 4, a screw rod 14 installed at the output end of the driving member 13, the screw rod 14 is threadedly connected with the slider 12, a slide groove 15 is installed on the conveying pipe 4, the slider 12 is slidably connected along the slide groove 15, the driving member 13 is electrically connected with the tracking extension module, when the slider 12 is controlled to move by the tracking extension module, at this time, by controlling the driving member 13 to work, the driving member 13 drives the screw rod 14 to rotate, thereby controlling the slider 12 to move back and forth, and the moving slider 12 moves along the slide groove 15, so that the tracking replenishment pipe 9 can move forward stably, and the front end of the tracking replenishment pipe 9 is connected to an extension nozzle 16, and the output end of the extension nozzle 16 faces the side away from the tracking replenishment pipe 9, and an electromagnetic valve 17 is installed between the extension nozzle 16 and the tracking replenishment pipe 9. A proximity switch 29 is installed on the inner wall of one end of the tube 9 away from the extension nozzle 16. The tracking extension module is electrically connected to the solenoid valve 17 and the proximity switch 29 respectively. When the driving member 13 drives the slider 12 and the tracking supplementary tube 9 to move synchronously through the screw 14, due to the limited length of the tracking supplementary tube 9, after the tracking supplementary tube 9 is extended to the longest distance, the proximity switch 29 in the tracking supplementary tube 9 contacts the piston plate 28. After receiving the signal, the proximity switch 29 sends it to the tracking extension module. The tracking extension module controls the driving member 13 to stop working and controls the solenoid valve 17 to open. The water in the tracking supplementary tube 9 enters the extension nozzle 16 and is sprayed toward the front end of the tracking supplementary tube 9 through the extension nozzle 16, further increasing the irrigation range, thereby increasing the coverage area of ​​the irrigation device and reducing irrigation dead angles.

[0046] Preferably, see Figure 1 and Figure 8 The land contour plate 7 is a two-stage structure. The two-stage land contour plate 7 is snapped onto the pumping assembly 2 by magnetic attraction, so it is convenient to replace it with a land contour plate 7 of corresponding size according to the shape of the irrigated land. The two-stage land contour plate 7 is convenient to be installed on the pumping assembly 2, thereby improving the convenience of installation. A plurality of self-propelled wheel assemblies 6 are provided, and the plurality of self-propelled wheel assemblies 6 are evenly distributed along the axial direction of the conveying pipe 4. A corresponding number of self-propelled wheel assemblies 6 are installed according to the length of the conveying pipe 4, so that the longer conveying pipe 4 can be driven to make a circular motion, thereby increasing the coverage area of ​​the conveying pipe 4.

[0047] The second implementation method:

[0048] Figure 2 , Fig. 9 and Fig.10An automatic irrigation device for artificial forests in high-cold areas is shown. Different from the first embodiment, the inner cavity of the air pressure cylinder 23 is slidably connected with a piston plate 232 fixed to the insertion rod 24, and the end of the air pressure cylinder 23 away from the insertion rod 24 is connected to a balance pipe 26, on which a solenoid valve 230 is installed. The tracking module is electrically connected to the solenoid valve 230, and the position of the delivery pipe 4 and the tracking wheel 27 is adjusted to the closest point to the pumping component 2. This state is the initial state. At this time, the tracking wheel 27 is attached to the outer side of the land contour plate 7. The air pressure sensor 31 can detect whether the air pressure in the air pressure cylinder 23 is zero, and by controlling the solenoid valve 230 to open, the internal and external air pressures of the air pressure cylinder 23 are balanced through the balance pipe 26, thereby calibrating the air pressure in the air pressure cylinder 23, improving the tracking accuracy of the contour tracking mechanism 8, and facilitating accurate control of the extension amount of the tracking supplementary pipe 9.

[0049] In this embodiment, an initial hydraulic pressure sensor 19 is installed on the top of the rotating tube 3, and a final hydraulic pressure sensor 20 is installed on the end of the delivery tube 4 away from the rotating tube 3. The auxiliary module is electrically connected to the initial hydraulic pressure sensor 19 and the final hydraulic pressure sensor 20 respectively. During normal irrigation, the water in the delivery tube 4 will enter the pressurized water pipe 18 for pre-storage. Due to the long length of the delivery tube 4, the water pressure at both ends of the delivery tube 4 has a certain difference, and the tracking supplementary tube 9 gradually extends, and the water in the delivery tube 4 enters the tracking supplementary tube 9, which will also reduce the water pressure at the far end of the delivery tube 4. When the auxiliary module passes through the initial hydraulic pressure The sensor 19 and the terminal hydraulic pressure sensor 20 calculate the difference between the two ends of the delivery pipe 4. When it is determined that the difference between the two ends of the delivery pipe 4 is greater than the pressure difference threshold (the maximum value of the water pressure difference between the two ends of the delivery pipe 4 is preset in the auxiliary module), the auxiliary module controls the booster pump 21 to work, injects the water in the booster water pipe 18 into the delivery pipe 4, increases the water pressure value at the far end of the delivery pipe 4, thereby balancing the water pressure difference between the two ends of the delivery pipe 4, and at the same time makes the pressure value in the delivery pipe 4 reach a qualified value, so that the irrigation sprinkler 5 on the delivery pipe 4 and the tracking sprinkler 10 on the tracking supplementary pipe 9 spray water evenly, irrigates the land evenly, and improves the irrigation effect.

[0050] Preferably, a pressure gauge 25 is installed at one end of the pressure cylinder 23 away from the insertion rod 24, and a through hole is opened at the end of the pressure cylinder 23 away from the pressure gauge 25. Through the installed pressure gauge 25, the air pressure in the pressure cylinder 23 can be intuitively understood during inspection, which is convenient for inspectors to understand the operating status of the equipment. Through the through hole opened on the pressure cylinder 23, the air pressure in the space on the side of the piston plate 23 close to the insertion rod 24 and the external air pressure can be balanced, so that the piston plate 23 can move smoothly during the pushing process of the insertion rod 24.

[0051] An irrigation method for an automatic irrigation device for artificial forests in high-cold areas, comprising the following steps:

[0052] S1. Dig a well or bury an irrigation pipe in the center of the land to form a fixed water source 1, install a pumping assembly 2 at the fixed water source 1 and connect it to a rotating pipe 3;

[0053] S2. Install the land contour plate 7 on the pumping assembly 2. The orientation of the land contour plate 7 is the same as the orientation of the land. Fit the tracking wheel 27 to the outer wall of the land contour plate 7. At this time, the air pressure cylinder 23 and the insertion rod 24 are located in the same straight line as the delivery pipe 4.

[0054] S3. The irrigation intelligent controller controls the pumping assembly 2 and the self-propelled wheel assembly 6 to irrigate the land. During the irrigation process, the tracking wheel 27 rolls along the outer contour track of the land contour plate 7. The irrigation intelligent controller sends a control signal to the tracking extension module through the pressure change in the inner cavity of the air pressure cylinder 23 to control the tracking supplementary pipe 9 to extend a corresponding distance.

[0055] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
