Description

[Technical Field]

[0001] The present invention relates to the technical field of sandy soil crop irrigation, and in particular to an irrigation device for the cultivation of sandy soil crops. [Background technology]

[0002] The sandy Gobi region experiences long hours of sunshine, making water shortages a key factor limiting crop cultivation in the region. Unreasonable irrigation methods not only result in inefficient consumption of freshwater resources but also exacerbate water conflicts. The development of water-saving irrigation equipment not only improves soil moisture and temperature but also promotes crop growth and nutrient absorption. Scientific and rational irrigation can improve the soil structure and fertility of sandy soil, increase the number and activity of microorganisms in the soil, and improve land use.

[0003] The applicant has previously designed a sandy soil irrigation device, which includes a fixing bracket, a water storage container, a storage bracket, an irrigation unit, a humidity sensor, and a controller, etc. The irrigation unit includes a group of conveying pipelines and an irrigation nozzle, the group of conveying pipelines includes a plurality of sections of conveying pipeline, the conveying pipelines have pipeline joints, the irrigation nozzles are connected to the pipeline joints, the plurality of sections of conveying pipeline are connectable to each other, the conveying pipelines are connectable to a conveying pump body, the humidity sensor is used to monitor the humidity inside the land, and the controller is electrically connected to the conveying pump body and the humidity sensor. When actually performing irrigation, on the one hand, the water storage capacity of such devices is fixed and cannot be adjusted according to the area of ​​cultivated land that needs irrigation. Especially when the area of ​​cultivated land is large, the device often needs to move back and forth between the cultivated land and the water extraction point multiple times, which reduces irrigation efficiency and increases irrigation costs. On the other hand, the irrigation width cannot be adjusted according to the width of the cultivated land. For cultivated land that is wider than the width of the irrigation device, irrigation often needs to be carried out multiple times. As a result, part of the cultivated land will be irrigated multiple times, which will result in both water waste and over-spraying and have a negative impact on crop growth. Summary of the Invention [Problem to be solved by the invention]

[0004] The main objective of the present invention is to provide an irrigation device for growing crops on sandy soil, which has an adjustable pull-out water tank assembly that can be adjusted according to the actual width of the cultivated land, thereby improving crop irrigation efficiency, and effectively overcoming the drawbacks of existing sandy soil irrigation devices, such as the inability to adjust the spray width range, which affects crop irrigation efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to make the above objects, features and advantages of the present invention more clear and easily understandable, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification.

[0024] Example 1 1 to 10, this embodiment provides an irrigation device for cultivating crops in sandy soil, which is composed of a water tank assembly 1, a latch spray assembly 2, a detection spray assembly 3, and a control unit. The irrigation device includes an outer tank body 11, an intermediate tank body 12, and an end tank body 13. End plates 14 are attached to the outer tank body 11 on the side remote from the intermediate tank body 12 and the end tank body 13 on the side remote from the intermediate tank body 12, respectively. One end of the intermediate tank body 12 is retractably restrained by the inner wall of the outer tank body 11, and one end of the end tank body 13 is retractably restrained by the inner wall of the intermediate tank body 12. The outer tank body 11, the intermediate tank body 12, the end tank body 13, and the end plates 14 form a tank body structure. By retracting the intermediate tank body 12 or the end tank body 13, the volume of the tank body can be increased or decreased, allowing the length of the water tank assembly 1 to be adjusted according to the crop cultivation width. At the same time, when the length of the water tank assembly 1 is adjusted, its water capacity also increases, thereby realizing the adjustability of the crop irrigation device.

[0025] A latch spray assembly 2 is attached to the top outer wall of the outer tank body 11 near one end of the intermediate tank body 12 and to the top outer wall of the intermediate tank body 12 near one end of the end tank body 13, respectively. The latch spray assembly 2 includes a locking bracket 21 and a first spray pipe 24, which is located on the top of the locking bracket 21. The locking bracket 21 is used to lock the outer tank body 11 and the intermediate tank body 12 together when they are retracted, or to lock the intermediate tank body 12 and the end tank body 13 together when they are retracted. The installation of the locking bracket 21 locks the outer tank body 11 and the intermediate tank body 12, or the intermediate tank body 12 and the end tank body 13, when they are retracted, thereby reducing the risk of the outer tank body 11, the intermediate tank body 12, or the end tank body 13 sinking up or down due to an excessively large water capacity, and improving the stability of the retracted water tank assembly 1 when in use.

[0026] A detection spray assembly 3 is provided on the end plate 14 away from the intermediate tank body 12. The detection spray assembly 3 includes a second spray pipe 36 and a support leg 31. One end of the support leg 31 is movably connected to the outer wall of the end plate 14 via a pin shaft. The center line of the rotation axis of the support leg 31 is perpendicular to the side wall of the end plate 14. A humidity detection head 32 is provided on one end of the support leg 31. A water pump 6 is mounted above the outer tank body 11. A water supply pipe 61 and a number of drain pipes 62 are connected to the water pump 6. The water supply pipe 61 penetrates into the outer tank body 11. A water inlet is provided at the top of the outer tank body 11 near the water supply pipe 61. The multiple drain pipes 62 are respectively connected to the corresponding second spray pipes 36 and first spray pipes 24. The humidity detection head 32 on the side not only serves to detect the humidity of the sandy soil in real time, but also, when the second spray pipe 36 rotates, the spray area of ​​the device can be further increased, making it suitable for use in sandy soil with a larger cultivation width.

[0027] In addition, a flow rate adjusting valve or the like may be further provided on each drain pipe 62.

[0028] The control unit can be a microcomputer, MCU, computer (PC), etc., and is connected to the humidity detection head 32, the driving motor of the water pump 6, and the flow control valve, etc., and can adjust the operating status of the water pump 6 and the flow control valve based on the soil humidity data detected by the humidity detection head 32, thereby achieving intelligent water-saving effects.

[0029] A moving assembly 4 is provided at the bottom of the water tank assembly 1, and the moving assembly 4 includes four moving wheels 42 and two sets of telescopic shaft assemblies 41 whose length is adjustable. A motor 44 is attached to the outer wall of the end plate 14 and is used to drive the four moving wheels 42 to rotate. The telescopic shaft assembly 41 can not only change according to the length of the water tank assembly 1, but also, after the change, the motor 44 can be started to ensure the rotation of the four moving wheels 42 at all times. At the same time, the two sets of telescopic shaft assemblies 41 play a supporting role at the bottom of the outer tank body 11, the middle tank body 12 and the end tank body 13, further improving the robustness of the water tank assembly 1.

[0030] In this example, when spray irrigating sandy soil, the width of the sand is first measured. If the cultivation width of the sandy soil is less than the maximum spray length of the device, only one set of devices is required. If the cultivation width of the sandy soil is greater than the maximum spray length of the device, the multiple of the length less than the maximum spray length of the device is used as the standard for the number of sets of devices to be used. When preparing for sand spraying, first pull out the middle tank body 12 or the middle tank body 12 and the end tank body 13 according to the required length, and at the same time pull out the telescopic shaft assembly 41 at the bottom of the water tank assembly 1. After the middle tank body 12 is fully pulled out, adjust the lock bracket 21 to lock the middle tank body 12 and the outer tank body 11, and then adjust the spray position of the first spray pipe 24. If the end tank body 13 is not pulled out, the water inlet valve of the first spray pipe 24 corresponding to the end tank body 13 will be closed, and the end tank body 13 will be The corresponding first spray pipe 24 does not spray water, the second spray pipe 36 unfolds as shown in Figure 1, the support leg 31 rotates downward, and the humidity detection head 32 detects the humidity of the sandy soil. After completing the adjustment operation, water is poured into the water inlet of the outer tank body 11, the water pump 6 and motor 44 are turned on, the first spray pipe 24 starts spraying, the second spray pipe 36 starts spraying, and the motor 44 moves forward according to the humidity situation detected by the humidity detection head 32, thereby achieving irrigation spray for sandy crops and avoiding insufficient or over-irrigation.

[0031] Example 2 Referring to FIGS. 1 to 5, the present embodiment differs from the first embodiment in the following respects.

[0032] The outer tank body 11, the intermediate tank body 12 and the end tank body 13 each have a quadrilateral structure, and the corners of the quadrilateral are rounded. The rounded shape ensures airtightness between the outer tank body 11 and the intermediate tank body 12, or between the intermediate tank body 12 and the end tank body 13, when the tank is pulled out. The water supply pipe 61 is located on the side away from the intermediate tank body 12, and the bottom end of the water supply pipe 61 extends close to the bottom of the outer tank body 11. The position of the water supply pipe 61 does not affect the pull-out fitting of the intermediate tank body 12 and the outer tank body 11.

[0033] Movable grooves 15 are opened on the inner wall of the outer tank body 11 and the inner wall of the intermediate tank body 12, respectively, and both ends of the movable grooves 15 do not extend to both ends of the outer tank body 11, nor do both ends of the movable grooves 15 extend to both ends of the intermediate tank body 12. Silica gel strips 16 are embedded in the outer wall of one end of the intermediate tank body 12 close to the outer tank body 11 and in the outer wall of one end of the end tank body 13 close to the intermediate tank body 12, respectively. The movable grooves 15 and the silica gel strips 16 each have a ring structure, and the silica gel strips 16 are restricted to move within the corresponding movable grooves 15.

[0034] In this embodiment, when the length of the water tank assembly 1 needs to be adjusted, the intermediate tank body 12 is pulled out, causing the silica gel strip 16 on the outer wall of the intermediate tank body 12 to move within the movable groove 15 on the inner wall of the outer tank body 11. After the intermediate tank body 12 is pulled out, the silica gel strip 16 is restricted within the corresponding movable groove 15. After water is poured into the outer tank body 11, the connection between the outer tank body 11 and the intermediate tank body 12 is kept airtight, thereby achieving stable use of the pull-out type adjustable capacity water tank assembly 1.

[0035] The other structures are the same as those in the first embodiment.

[0036] Example 3 Referring to FIGS. 1 to 5, the present embodiment differs from the second embodiment in the following respects.

[0037] The lock bracket 21 has a U-shaped structure that opens downward, and both sides of the vertical part of the lock bracket 21 are attached to the outer wall of the outer tank body 11 or the intermediate tank body 12. A plurality of T-shaped lock pins 26 are horizontally inserted into both sides of the vertical part of the lock bracket 21. At least three sets of T-shaped lock pins 26 are provided on the vertical part of one side of the lock bracket 21, and tension springs 27 are fitted on the T-shaped lock pins 26. Through holes that are slidably fitted with the T-shaped lock pins 26 are opened on the side of the outer tank body 11 close to the intermediate tank body 12 and on the side of the intermediate tank body 12 close to the end tank body 13, and the through holes are located away from the movable groove 15, and the side of the outer wall of the intermediate tank body 12 close to the outer tank body 11 and the side of the outer wall of the end tank body 13 close to the intermediate tank body 13 are An insertion groove for the T-shaped locking pin 26 is provided on the side closest to the body 12, and both ends of the corresponding tension spring 27 are connected between the outer wall of the outer tank body 11 and the inner wall of the locking bracket 21, or between the outer wall of the intermediate tank body 12 and the inner wall of the locking bracket 21. When the intermediate tank body 12 is in a withdrawn state, the end of the T-shaped locking pin 26 abuts against the outer wall of the intermediate tank body 12 until the insertion groove of the intermediate tank body 12 is withdrawn to the end of the intermediate tank body 12. Under the drive of the tension spring 27, the T-shaped locking pin 26 is inserted horizontally into the outer tank body 11 and the intermediate tank body 12, limiting the horizontal positions of the outer tank body 11 and the intermediate tank body 12, thereby reducing the occurrence of sinking of the outer tank body 11 and the intermediate tank body 12.

[0038] A slide rail 22 is opened at the top of the locking bracket 21, and an I-shaped slider 23 is slidably mounted within the slide rail 22. The first spray pipe 24 has a T-shaped structure, and the bottom of the first spray pipe 24 is movably connected to the I-shaped slider 23 via a bearing sleeve. A number of first spray heads 25 are attached to the top of the first spray pipe 24. The first spray pipe 24 rotates laterally around the I-shaped slider 23, and the multiple first spray heads 25 are distributed above the water tank assembly 1. After the water tank assembly 1 is fully deployed, the multiple first spray heads 25 are distributed above the outer tank body 11, middle tank body 12 and end tank body 13. By pulling out the I-shaped slider 23 from its position on the slide rail 22, the first spray pipe 24 can be moved on the slide rail 22 as needed, and the spray position can be moved to the front or rear of the tank body assembly 1, thereby achieving flexible spray adjustment.

[0039] In this embodiment, a U-shaped locking bracket 21 is provided, which uses the U-shaped structure to limit widthwise deformation of the connection between the outer tank body 11 and the intermediate tank body 12, and the connection between the intermediate tank body 12 and the end tank body 13, while the T-shaped locking pin 26 abuts against the insertion groove through the through hole, ensuring the robustness of the horizontal position after the outer tank body 11, the intermediate tank body 12 and the end tank body 13 are pulled out, and improving the stability of the pull-out type water tank assembly 1.

[0040] The other structures are the same as those in the second embodiment.

[0041] Example 4 Referring to FIGS. 1, 2, 6 and 7, the present embodiment differs from the second embodiment in the following respects.

[0042] The detection spray assembly 3 further includes a pallet 34, one end of which is movably connected to the end plate 14 via a pin shaft. When the support leg 31 is rotated horizontally, it is placed on the pallet 34. When the support leg 31 is rotated vertically, the humidity detection head 32 is inserted into the sandy soil. The support leg 31 has a large mass and weight, so when the support leg 31 is rotated horizontally, it is placed on the pallet 34, making it easy to store. When the support leg 31 is rotated vertically, the humidity detection head 32 is inserted into the sandy soil under the action of gravity, allowing the humidity of the sandy soil to be detected in real time during spraying, thereby achieving accurate spray volume and rational spraying.

[0043] A second engagement groove 342 is formed on the top of the pallet 34, and a rotation groove 341 is provided at one end of the second engagement groove 342. L-shaped engagement strips 35 are attached to both sides of the second engagement groove 342 on the top of the pallet 34. A first engagement groove 311 is formed on one side of the support leg 31, and L-shaped engagement plates 33 are attached to both sides of the first engagement groove 311 on the outer wall of the support leg 31. When the support leg 31 is placed on the pallet 34, the first engagement groove 311 and the rotation groove 341 are connected to each other, and a second spray head 37 is attached to one end of the second spray pipe 36. The second spray pipe 36 is attached to the first end of the second spray pipe 36, and a disk 38 is connected to the other end of the second spray pipe 36. A waist plate 39 is attached to the bottom of the disk 38, and the disk 38 is restricted to slide within the L-shaped engagement plate 33 or the L-shaped engagement strip 35. The width of the waist plate 39 is smaller than the diameter of the disk 38. When the waist plate 39 is restricted within the first engagement groove 311 and the second engagement groove 342, it can only move linearly. When the waist plate 39 is restricted within the rotation groove 341, it can only rotate circularly. When the disk 38 is restricted within the L-shaped engagement plate 33 or the L-shaped engagement strip 35, it can only slide linearly.

[0044] In this embodiment, in the initial state, the support leg 31 is horizontal and placed on the pallet 34, the second spray pipe 36 is parallel to the support leg 31, the waist plate 39 is restricted in the first engaging groove 311, the disc 38 is restricted in the L-shaped engaging plate 33, and the second spray pipe 36 is stored above the support leg 31. In use, the waist plate 39 is first pushed along the L-shaped engaging plate 33 into the rotating groove 341, and then the second spray pipe 36 is rotated outward by 90° to be deployed, and then moved linearly along the second engaging groove 342, so that the disc 38 is restricted to slide within the L-shaped engaging strip 35. Then, the support leg 31 is rotated from the horizontal state to the vertical state, and the humidity detection head 32 is inserted vertically into the sandy soil as shown in FIG. 1. In this way, the humidity detection head 32 can be easily stored, and when not in use, the humidity detection head 32 can be easily stored. The humidity detection head does not come into contact with the ground, avoiding friction with the ground. When the support leg 31 is in the retracted state, the second spray pipe 36 can be easily retracted. The second spray pipe 36 is retracted so that it is parallel to the end plate 14, thereby saving space occupied by the irrigation device when it is not in operation. When the humidity detection head 32 needs to be used, the gravity of the support leg 31 causes the humidity detection head 32 to be inserted into the soil. Since the humidity detection head 32 is inserted into the soil while the irrigation device is moving, it can more accurately detect the humidity condition of sandy soil and the humidity condition after spraying in real time than when it falls onto the soil surface, thereby realizing scientific irrigation of sandy soil. When the second spray pipe 36 is extended outward perpendicular to the end plate 14, a wider spray range of the irrigation device can be achieved according to the needs of sandy irrigation.

[0045] The other structures are the same as those in the third embodiment.

[0046] Example 5 Referring to FIGS. 1, 2, 8, 9 and 10, the present embodiment differs from the second embodiment in the following respects.

[0047] The telescopic shaft assembly 41 includes a first rectangular telescopic tube 411, a second rectangular telescopic tube 412 inserted into one end of the first rectangular telescopic tube 411, and a third rectangular telescopic tube 413 inserted into one end of the second rectangular telescopic tube 412 remote from the first rectangular telescopic tube 411. The cross section of the telescopic shaft assembly 41 is a rectangular tube structure.
