Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a water-saving drip irrigation device for farmland water conservancy projects, comprising a vehicle body 1 and a lifting frame 7, a water tank 2 is installed above the vehicle body 1, a stirring assembly 3 is installed on the inner side of the water tank 2, a lifting mechanism 8 is installed at one end of the vehicle body 1, the lifting frame 7 is installed on the outside of the lifting mechanism 8, and a support frame 6 is fixed to one end of the vehicle body 1 close to the lifting frame 7.

[0028] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 A drip irrigation mechanism 5 is arranged above the support frame 6 and the lifting frame 7. The lifting mechanism 8 includes a screw 801, a first gear 802, a second gear 803 and a motor 804. A screw 801 is installed at one end of the vehicle body 1 through a bearing. The screw 801 and the lifting frame 7 are threadedly connected. The outer side of the screw 801 is fixedly sleeved with a first gear 802. One side of the first gear 802 is meshedly connected with a second gear 803. A motor 804 connected to the second gear 803 through a coupling is installed on the inner side of the bracket of the vehicle body 1. A water pump 4 is connected to one side of the vehicle body 1, and the water pump 4 is connected to the drip irrigation mechanism 5. The drip irrigation mechanism 5 comprises a hose 501, a water inlet pipe 502, a connecting frame 503, a guide pipe 504, a dropper 505 and a telescopic rod 506. The water inlet pipe 502 runs through the top of the lifting frame 7. The two ends of the water inlet pipe 502 are connected to the guide pipe 504. One side of the water inlet pipe 502 is connected to the water pump 4 through the hose 501. The guide pipe 504 is connected to the dropper 505 at equal intervals below. The inner side of the support frame 6 is slidably sleeved with a telescopic rod 506, and the telescopic rod 506 is sleeved with the guide pipe 504. There are two groups of telescopic rods 506 and the support frame 6.

[0029] In specific implementation, since the heights of the dripper 505 and the conduit of the existing water-saving farmland water conservancy project drip irrigation device are usually fixed, but the heights of crop seedlings are different, it is inconvenient to adjust the heights of the dripper 505 and the conduit, which affects the working quality of the drip irrigation device. When it is necessary to adjust the height of the guide tube 504 and the dripper 505, the first gear 802 can be driven to rotate by starting the motor 804, the first gear 802 drives the second gear 803 to rotate, and the second gear 803 drives the screw rod 801 to rotate. The screw rod 801 is threadedly engaged with the lifting frame 7, and then the lifting frame 7 moves upward on the outside of the screw rod 801. At the same time, the lifting frame 7 drives the water inlet pipe 502 and the guide pipe 504 to move upward. The guide pipe 504 pulls the telescopic rod 506 to slide upward on the inside of the support frame 6. Then the guide pipe 504 drives the drip pipe 505 to move upward. The height of the drip pipe 505 can be quickly adjusted, which is convenient for drip irrigation of seedlings at different heights, thereby improving the practicality and work quality of the drip irrigation device used in water-saving farmland water conservancy projects.

[0030] See also Figure 1-Figure 3 and Figure 6-Figure 8 A quantitative box 13 is installed on one side of the water tank 2 by bolts, and a quantitative mechanism 9 is installed on the inner side of the quantitative box 13. A feeding trough 10 is opened at the bottom of the quantitative box 13, and a liquid outlet pipe 11 is connected to the quantitative box 13 below the feeding trough 10. One end of the liquid outlet pipe 11 is connected to the water tank 2, and a stand 12 is installed above the water tank 2. The quantitative mechanism 9 includes a baffle 901, a quantitative cylinder 902, a reset spring 903 and a pull rod 904. A quantitative cylinder 902 is provided in the built-in groove of the quantitative box 13, one end of the quantitative cylinder 902 is connected to the baffle 901, and the other end of the quantitative cylinder 902 is connected to the pull rod 904, and the outer side of the pull rod 904 is sleeved with a reset spring 903. The pull rod 904 slides through one side of the quantitative box 13, and both sides of the quantitative cylinder 902 are connected to sliders 14 slidably connected to the quantitative box 13. A liquid inlet is provided above the quantitative box 13.

[0031] In the specific implementation, before the drip irrigation works, the nutrient solution or the medicine solution needs to be put into the water tank 2 and mixed with the water, but it is not convenient to manually add the nutrient solution or the medicine solution in a quantitative manner, which affects the convenience of the drip irrigation device for water-saving farmland water conservancy projects. The bottle of the nutrient solution or the medicine solution can be inverted on the inner side of the stand 12 so that the bottle mouth extends into the quantitative box 13, and then the nutrient solution or the medicine solution enters the quantitative cylinder 902. The staff then pulls the pull rod 904, so that the pull rod 904 drives the quantitative cylinder 902 to move in the quantitative box 13. The dosing cylinder 902 moves, and at the same time, the slider 14 slides in the built-in groove of the dosing box 13, and the pull rod 904 squeezes the return spring 903. When the dosing cylinder 902 reaches the feed trough 10, the baffle 901 blocks the liquid inlet of the dosing box 13 to prevent the nutrient solution or the medicine solution from overflowing when the dosing cylinder 902 guides the liquid. The nutrient solution or the medicine solution entering the feed trough 10 is then introduced into the water tank 2 through the liquid outlet pipe 11, which is convenient for the staff to manually add liquid quantitatively, thereby improving the convenience of the drip irrigation device for water-saving farmland water conservancy projects.

[0032] Working principle: When using the drip irrigation device for water-saving farmland water conservancy projects, water is first introduced into the water tank 2, and the nutrient solution or medicine solution is quantitatively added to the water tank 2 through the quantitative mechanism 9, and then the water and the nutrient solution or medicine solution are mixed through the stirring component 3, and then the mixed liquid is transported into the drip irrigation mechanism 5 through the water pump 4. The height of the drip irrigation mechanism 5 is adjusted by the lifting mechanism 8, and drip irrigation is performed on seedlings at different heights, thereby improving the practicality and convenience of the drip irrigation device for water-saving farmland water conservancy projects.
