The water ring box 9 is provided with a water outlet hole 13, and the water outlet hole 13 is provided with a plurality of groups. The plurality of groups of water outlet holes 13 are sequentially arranged from top to bottom along the side wall of the water ring box 9. The water storage tank 8 is connected to the inspection door 14, and the water storage tank can be opened through the inspection door 14 8, and then the water outlet hole 13 at the corresponding position can be blocked, so that the water receiving ring box 9 only retains one water outlet hole 13, and then the water storage capacity of the water receiving ring box 9 is controlled. The water receiving ring box 9 is connected to the inner side of the water pump 10, and the water pump 10 is connected to the water pipe 26, and the water pipe 26 is connected to the delivery pipe 5. The water storage tank 8 is connected to the stirring shaft 11, and the stirring shaft 11 and the first threaded rod 12 are respectively connected to the second transmission sprocket 18, and the two sets of second transmission sprockets 18 are commonly connected to the second transmission chain 22, and the stirring shaft 11 can rotate with the first threaded rod 12 through the second transmission chain 22 and the second transmission sprocket 18.

The structure and use principle of the battery are all existing technologies well known to practitioners in this field and will not be repeated here.

[0026] The fixed rod 1 is provided with a mounting groove 28 and a sliding groove 29, the inner side of the mounting groove 28 is connected with a second motor 30, the inner side of the sliding groove 29 is rotatably connected with an adjusting threaded rod 2, the adjusting threaded rod 2 is connected with the output shaft of the second motor 30, the adjusting threaded rod 2 is threadedly connected with a moving block 3, the moving block 3 is slidably connected with the sliding groove 29, and the sliding groove 29 can play a role of rotation limiting the moving block 3, the moving block 3 is connected with a mounting frame 4, the two ends of the conveying pipe 5 are respectively connected with two groups of mounting frames 4, the mounting frame 4 is rotatably connected with the moving block 3, the mounting frame 4 is slidably connected with a limiting square rod 31, the limiting square rod 31 is connected with a magnet block 35, and the magnet block 35 and the mounting frame 4 are mutually connected The magnet block 35 can be adsorbed on the installation frame 4, and the moving block 3 is provided with a limiting square groove 32. The limiting square rod 31 cooperates with the limiting square groove 32. The limiting square rod 31 can be inserted into the limiting square groove 32, thereby limiting the movement of the installation frame 4 relative to the moving block 3. The limiting square rod 31 is connected with a positioning block 33. The inner side wall of the limiting square groove 32 and the installation frame 4 are respectively provided with positioning grooves 34. The positioning block 33 is slidably connected with the positioning groove 34. Through the cooperation of the positioning block 33 and the positioning groove 34, the limiting square rod 31 cannot slide out of the installation frame 4, thereby improving the stability of use. There are two groups of limiting square grooves 32, and the verticality and folding of the conveying pipe 5 are realized by the two groups of limiting square grooves 32.

[0027] The inner wall of the bottom of the sliding groove 29 is higher in the middle and lower on both sides, so that dust will not accumulate inside the sliding groove 29. The water tank 8 is connected to the protective frame 21, the first motor 20 is located inside the protective frame 21, and the water tank 8 is connected to the water injection pipe 24.

After the limiting square rod 31 slides out of the limiting square groove 32, the positioning block 33 can rotate relative to the moving block 3, and then the conveying pipe 5 and the fixed rod 1 can be folded and placed, and then the limiting square rod 31 can be inserted into the corresponding limiting square groove 32 to limit the position again.

[0029] The specific implementation process is as follows:

[0030] When in use, two sets of fixing rods 1 are connected to the left and right sides of the farmland respectively, and the conveying pipe 5 is rotated to a vertical state, such as Figure 1As shown, the first motor 20 and the second motor 30 are started, and the first motor 20 and the second motor 30 are started intermittently. When the device is not in use, the water receiving ring box 9 is located at the bottom of the water storage tank 8, the inspection door 14 is opened, the corresponding water outlet is blocked, and irrigation water or medicine is added to the water storage tank 8 through the water injection pipe 24. At this time, the inside of the water receiving ring box 9 is full of water. After the first motor 20 is started, it drives the water receiving ring box 9 to move upward, and at the same time stirs the irrigation water or medicine. The water receiving ring box 9 moves upward and gradually moves out of the liquid level of the water storage tank 8. Excess water in the water receiving ring box 9 is discharged from the water outlet 13. As a result, the water receiving ring box 9 only stores the same amount of water each time. As the water receiving ring box 9 rises, the water receiving ring box 9 contacts the first switch and the second switch. At this time, the first motor 20 stops, and the first switch and the second switch are contacted, so that the water pump 10 is turned on and the solenoid valve is turned on. The water pump 10 transports the irrigation water in the water receiving ring box 9 along the water pipe 26, the delivery pipe 5 and the water spray pipe 6, and finally sprays it from the nozzle 7 to irrigate the farmland until the irrigation water in the water receiving ring box 9 is output. The first motor 20 is stopped at intervals during the water spraying period, that is, after a period of time The first motor 20 will start again, and after the first motor 20 starts again, it drives the first threaded rod 12 and the second threaded rod 27 to reverse, so that the water receiving ring box 9 moves down. At this time, the water pump 10 and the solenoid valve are closed, and the water receiving ring box 9 moves down and falls below the liquid level of the water storage tank 8 again. At this time, the first motor 20 stops again at intervals, so that the water receiving ring box 9 is filled with water again. At this time, the second motor 30 is also started, and the second motor 30 drives the moving block 3 and the conveying pipe 5 to move backward to adjust the water spraying distance. After adjusting to the appropriate distance, the second motor 30 stops at intervals for a period of time. Afterwards, the first motor 20 is started again, driving the water receiving ring box 9 to move upward, and the comprehensive quantitative irrigation of the farmland is completed according to the above steps. As for the opening and closing of the first motor 20, the first motor 20 is opened and closed at a set time interval, and at the same time, it is opened and closed in an interval sequence along the forward and reverse rotation of the first threaded rod 12. The second motor 30 is opened and closed at a set time interval, and each interval opening and closing drives the adjusting threaded rod 2 to rotate in the same direction at the same speed. The interval opening and closing settings of the first motor 20 and the second motor 30 are both existing technologies well known to practitioners in this field and will not be repeated here.

[0031] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
