Description

Technical Field

[0001] The invention relates to the technical field of sandy land crop irrigation, and in particular to an irrigation device used for planting sandy land crops. Background Art

[0002] The long sunshine hours in the sandy Gobi region and the shortage of water resources are one of the important factors restricting the planting of crops in the region. Unreasonable irrigation methods not only cause ineffective consumption of freshwater resources, but also aggravate water use conflicts. The development of water-saving irrigation equipment can not only increase the humidity and temperature of the soil, but also help the growth of crops and the absorption of nutrients. Scientific and reasonable irrigation can improve the structure and fertility of sandy soil, increase the number and activity of microorganisms in the soil, and improve land utilization.

[0003] The applicant has previously designed a sand irrigation device, including a fixed bracket, a water storage container, a storage rack, an irrigation unit, a humidity sensor and a controller, etc. The irrigation unit includes a delivery pipeline group and an irrigation nozzle, the delivery pipeline group includes multiple sections of delivery pipelines, a pipeline joint is provided on the delivery pipeline, the irrigation nozzle is connected to the pipeline joint, the multiple sections of delivery pipelines can be connected to each other, and the delivery pipeline can also be connected to the delivery pump body, the humidity sensor is used to monitor the humidity inside the land, and the controller is connected to the delivery pump body and the humidity sensor. During actual irrigation, the device has a fixed water storage capacity and cannot be adjusted according to the area of ​​​​cultivated land to be irrigated. Especially for large areas of arable land, it is often necessary to make the device go back and forth between the arable land and the water intake area many times, which reduces the irrigation efficiency and increases the irrigation cost. On the other hand, the irrigation width cannot be adjusted according to the width of the arable land. For arable land with a width greater than the width of the irrigation device, it is often necessary to irrigate multiple times, which is very likely to cause some areas in the arable land to be repeatedly irrigated, which will not only waste water resources, but also cause excessive spraying, affecting the growth of crops.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0044] Example 1

[0045] Reference Figure 1-10This embodiment provides an irrigation device for planting crops in sandy land, which includes a water tank assembly 1, a lock spray assembly 2, a detection spray assembly 3, a control unit, etc. The water tank assembly 1 includes an outer box 11, an intermediate box 12, and an end box 13. The side of the outer box 11 away from the intermediate box 12 and the side of the end box 13 away from the intermediate box 12 are respectively installed with end plates 14. One end of the intermediate box 12 is limited to the inner wall of the outer box 11 for pulling and pulling, and one end of the end box 13 is limited to the inner wall of the intermediate box 12 for pulling and pulling. The outer box 11, the intermediate box 12, the end box 13, and the end plate 14 form a box structure. By pulling the intermediate box 12 or the end box 13, the volume of the box becomes larger or smaller. The length of the water tank assembly 1 can be adjusted according to the width of the crop planting. At the same time, when the length of the water tank assembly 1 is increased, its water capacity is also increased, realizing the adjustability of the crop irrigation device.

[0046] The top outer wall of the outer box 11 near one end of the middle box 12 and the top outer wall of the middle box 12 near one end of the end box 13 are respectively installed with a locking spray assembly 2, which includes a locking frame 21 and a first spray pipe 24. The first spray pipe 24 is arranged on the top of the locking frame 21. The locking frame 21 is used to lock the outer box 11 and the middle box 12 in the pulled-out state, or to lock the middle box 12 and the end box 13 in the pulled-out state. The setting of the locking frame 21 is used to lock the outer box 11 and the middle box 12 in the pulled-out state, or the middle box 12 and the end box 13, so as to reduce the excessive water capacity, which causes the outer box 11, the middle box 12 or the end box 13 to sink up and down, thereby ensuring the stability of the pulled-out water tank assembly 1 in use.

[0047] A detection spray assembly 3 is provided on the side of the end plate 14 away from the middle box 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 by a pin shaft. 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 installed at one end of the support leg 31. A water pump 6 is installed above the outer box body 11. The water pump 6 is connected to an upper water pipe 61 and a plurality of water outlet pipes 62. The upper water pipe 61 penetrates into the outer box body 11. A water inlet is provided at the top of the outer box body 11 near the upper water pipe 61. The plurality of water outlet pipes 62 are respectively connected to the corresponding second spray pipe 36 and the first spray pipe 24. The humidity detection head 32 on the side not only has the effect of real-time detection of sand humidity, but also after the second spray pipe 36 is rotated, the spraying area of ​​the device can be further expanded to adapt to the use of sand with a larger planting width.

[0048] In addition, a flow regulating valve or the like may be provided on each water outlet pipe 62 .

[0049] The control unit can be a single-chip microcomputer, MCU or computer (PC), etc., which can be connected to the above-mentioned humidity detection head 32, the driving motor of the water pump 6 and the above-mentioned flow control valve, and can adjust the working state of the water pump 6 and the flow control valve according to the soil moisture data detected by the humidity detection head 32, thereby achieving the effect of intelligent water saving.

[0050] A moving assembly 4 is provided at the bottom of the water tank assembly 1. The moving assembly 4 includes four moving wheels 42 and two sets of telescopic shaft assemblies 41 with adjustable lengths. A motor 44 is installed on the outer wall of the end plate 14. The motor 44 is used to drive the four moving wheels 42 to rotate. The telescopic shaft assembly 41 can not only change with the length of the water tank assembly 1, but also after the change, the motor 44 can always ensure the rotation of the four moving wheels 42 when it is turned on. At the same time, the two sets of telescopic shaft assemblies 41 play a supporting role at the bottom of the outer box body 11, the middle box body 12 and the end box body 13, thereby further improving the stability of the water tank assembly 1.

[0051] In this embodiment, when spraying and irrigating the sandy land, the width of the sandy land is first measured. If the planting width of the sandy land is smaller than the maximum spraying length that the device can deploy, then one set of devices can be used. If the planting width of the sandy land is larger than the maximum spraying length that the device can deploy, then a multiple smaller than the maximum spraying length that the device can deploy is taken as a reference for the number of sets of devices to be used.

[0052] When preparing to spray on the sand, first pull the middle box 12 or the middle box 12 and the end box 13 according to the required length. At the same time, the telescopic shaft assembly 41 at the bottom of the water tank assembly 1 cooperates to stretch. When the middle box 12 is fully pulled out, adjust the locking frame 21 to lock the middle box 12 with the outer box 11, and then adjust the spraying position of the first spray pipe 24. If the end box 13 is not pulled out, the water inlet valve of the first spray pipe 24 corresponding to the end box 13 is closed, and the first spray pipe 24 corresponding to the end box 13 does not spray water, and the second spray pipe 36 is as shown in FIG. Figure 1 The support leg 31 is unfolded as shown, and the support leg 31 is rotated downward, and the humidity of the sand is detected by the humidity detection head 32. After the adjustment work is completed, water is injected into the water injection port of the outer box 11, the water pump 6 and the 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 detected by the humidity detection head 32, thereby realizing irrigation and spraying of crops in the sand and avoiding insufficient or excessive irrigation.

[0053] Example 2

[0054] Reference Figure 1-5 The difference between this embodiment and embodiment 1 is that:

[0055] The outer box body 11, the middle box body 12 and the end box body 13 are respectively square structures, and the corners of the square are rounded. The rounded shape can ensure the tightness between the outer box body 11 and the middle box body 12, or the middle box body 12 and the end box body 13 in the pulling state. The water supply pipe 61 is arranged on the side away from the middle box body 12, and the bottom end of the water supply pipe 61 extends close to the bottom of the outer box body 11. The position of the water supply pipe 61 does not affect the pulling and pulling coordination between the middle box body 12 and the outer box body 11.

[0056] The inner wall of the outer box body 11 and the inner wall of the middle box body 12 are respectively provided with movable grooves 15, and the two ends of the movable groove 15 do not extend to the two ends of the outer box body 11, and the two ends of the movable groove 15 do not extend to the two ends of the middle box body 12. The outer wall of one end of the middle box body 12 close to the outer box body 11 and the outer wall of one end of the end box body 13 close to the middle box body 12 are respectively embedded with silicone strips 16, and the movable groove 15 and the silicone strip 16 are respectively annular structures, and the silicone strip 16 is limited to move in the corresponding movable groove 15.

[0057] In this embodiment, when the length of the water tank assembly 1 needs to be adjusted, the middle box body 12 is pulled, and the silicone strip 16 on the outer wall of the middle box body 12 moves in the movable groove 15 on the inner wall of the outer box body 11. After the middle box body 12 is pulled, the silicone strip 16 is limited in the corresponding movable groove 15. When water is filled in the outer box body 11, the sealing of the connection between the outer box body 11 and the middle box body 12 can be guaranteed, thereby realizing the stability of the use of the pull-out adjustable capacity water tank assembly 1.

[0058] The remaining structures are the same as those of Example 1.

[0059] Example 3

[0060] Reference Figure 1-5 The difference between this embodiment and embodiment 2 is that:

[0061] The locking frame 21 is a U-shaped structure with an opening facing downward. Both sides of the vertical portion of the locking frame 21 are installed with the outer wall of the outer box body 11 or the middle box body 12. Both sides of the vertical portion of the locking frame 21 are horizontally plugged with multiple T-shaped locking pins 26. At least three groups of T-shaped locking pins 26 are arranged on the vertical portion of one side of the locking frame 21. A tension spring 27 is sleeved on the T-shaped locking pin 26. A through hole for sliding cooperation of the T-shaped locking pin 26 is opened on the side of the outer box body 11 close to the middle box body 12, and on the side of the middle box body 12 close to the end box body 13, and the through hole is located away from the movable groove 15. The outer wall of the middle box body 12 closes to the outer box body 11, and the outer wall of the end box body 13 closes to the middle box body 1 2 is provided with a slot for inserting a T-shaped locking pin 26, and the two ends of the corresponding tension spring 27 are connected between the outer wall of the outer box body 11 and the inner wall of the locking frame 21, or the two ends of the corresponding tension spring 27 are connected between the outer wall of the middle box body 12 and the inner wall of the locking frame 21. When the middle box body 12 is in the pulled state, the end of the T-shaped locking pin 26 abuts against the outer wall of the middle box body 12 until the slot of the middle box body 12 is pulled to the end of the middle box body 12. Driven by the tension spring 27, the T-shaped locking pin 26 horizontally inserts the outer box body 11 and the middle box body 12 to limit the horizontal position of the outer box body 11 and the middle box body 12, thereby reducing the occurrence of settlement of the outer box body 11 and the middle box body 12.

[0062] A slide rail 22 is provided at the top of the locking frame 21, and an I-shaped slider 23 is slidably arranged in the slide rail 22. The first spray pipe 24 is in a T-shaped structure. The bottom of the first spray pipe 24 is movably connected to the I-shaped slider 23 through a bearing sleeve. A plurality of first spray heads 25 are installed on the top of the first spray pipe 24. The first spray pipe 24 can rotate around the I-shaped slider 23 to a horizontal state, so that the plurality of first spray heads 25 are distributed above the water tank assembly 1. When the water tank assembly 1 is fully unfolded, the plurality of first spray heads 25 are distributed above the outer box body 11, the middle box body 12 and the end box body 13. By pulling the position of the I-shaped slider 23 on the slide rail 22, the first spray pipe 24 can be moved on the slide rail 22 according to needs to adjust the spray position to the front side of the box assembly 1 or the rear side of the box assembly 1, thereby achieving a flexibly adjustable spray effect.

[0063] In this embodiment, a U-shaped locking frame 21 is provided. On the one hand, the U-shaped structure is used to limit the deformation in the width direction at the connection between the outer box body 11 and the middle box body 12, and the connection between the middle box body 12 and the end box body 13. On the other hand, the T-shaped locking pin 26 passes through the through hole and abuts against the slot, thereby ensuring the stability of the horizontal position of the outer box body 11, the middle box body 12 and the end box body 13 after being pulled out, thereby improving the stability of the pull-out water tank assembly 1.

[0064] The remaining structure is the same as that of Example 2.

Figure 1As shown, the humidity detection head 32 is vertically inserted into the sandy soil. This arrangement allows the humidity detection head 32 to be easily stored. When the humidity detection head 32 is not in use, the humidity detection head will not touch the ground to avoid friction with the ground. Moreover, when the support legs 31 are in the stored state, it is also convenient to store the second spray pipe 36, so that the second spray pipe 36 is stored parallel to the end plate 14, saving the occupied space of the irrigation device in the non-working state; when the humidity detection head 32 is needed, the gravity of the support legs 31 can be used to insert the humidity detection head 32 into the soil. When the irrigation device is moving, the humidity detection head 32 extends into the soil. Compared with falling on the soil surface, the humidity state of the sandy soil and the humidity state after spraying can be more accurately and in real time detected, thereby improving the scientific irrigation of the sandy soil; when the second spray pipe 36 is unfolded outward perpendicular to the end plate 14, a wider spray range of the irrigation device can be achieved according to the sandy irrigation needs.
