Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-6 The utility model provides an embodiment of a nutrient solution drip irrigation device for agricultural and forestry planting with controllable flow rate, comprising a drip irrigation device body 1, a liquid outlet 5, a flow channel 6 and a dripper 7. A liquid inlet 2 is provided at one end of the top of the drip irrigation device body 1, and a liquid outlet 5 is provided at the bottom end of the drip irrigation device body 1, and a dripper 7 is provided at the bottom end of the liquid outlet 5;

Support rods 9 are sleeved inside the sleeves 8, and the top ends of the support rods 9 are connected to the drip irrigation device body 1 through fixing plates 23.

[0025] Screw holes 24 are evenly formed on the support rod 9, and the sleeve 8 is fixedly connected to the screw holes 24 through fasteners 25;

[0026] By pulling the support rod 9 out of the sleeve 8 to a certain length and locking the screw hole 24 at the corresponding position with the fastener 25, the height of the drip irrigation device body 1 can be adjusted. The height position of the dripper 7 can be adjusted according to the planting position of the agricultural and forestry crops so that it is located above the soil of the agricultural and forestry crops.

[0027] A rotating shaft 4 is provided inside the drip irrigation device body 1, and blades 22 are evenly distributed on the rotating shaft 4. A first drive motor 3 is fixed at the center of the top of the drip irrigation device body 1, and the output end of the first drive motor 3 is connected to the rotating shaft 4.

[0028] The nutrient solution is introduced into the drip irrigation device body 1 through the liquid inlet 2, and the first drive motor 3 drives the rotating shaft 4 and the blades 22 to rotate, stirring the nutrient solution evenly;

[0029] The top of the liquid outlet 5 is connected to the bottom of the drip irrigation device body 1 through a connecting pipe. A valve is provided on the connecting pipe. When the valve is opened, the nutrient solution passes through the liquid outlet 5 and then drips out through the dripper 7 to the roots of agricultural and forestry crops.

[0030] The dripper 7 has an inverted conical structure, and the water outlet of the dripper 7 is evenly provided with mesh holes 21 to ensure that the nutrient solution drips out evenly, thereby achieving uniform irrigation of agricultural and forestry crops and helping the roots to better absorb nutrients;

[0031] A plug 15 is provided on one side of the liquid outlet 5, and a sealing gasket 17 is provided on the other side of the liquid outlet 5, and a flow channel 6 is formed between the sealing gasket 17 and the plug 15;

[0032] A screw rod 12 is provided in the liquid outlet part 5 on one side of the plug 15, and a movable sleeve 13 is provided on the outer side of the screw rod 12. One end of the movable sleeve 13 is connected to the plug 15. A second drive motor 11 is fixed to one side of the liquid outlet part 5, and the output end of the second drive motor 11 is connected to the screw rod 12.

[0033] The second drive motor 11 drives the screw rod 12 to rotate, so that the movable sleeve 13 moves along the screw rod 12, driving the plug 15 at one end of the movable sleeve 13 to adjust its position, thereby adjusting the space size of the flow channel 6 inside the liquid outlet 5;

[0034] The larger the internal space of the flow channel 6, the smaller the resistance to the passage of the nutrient solution, and the greater the flow rate. By controlling the position of the plug 15 inside the liquid outlet 5, the flow rate of the nutrient solution can be controlled. The flow rate can be adjusted according to the type and growth stage of the agricultural and forestry crops, thereby flexibly adjusting the irrigation amount.

[0035] Guide grooves 14 are provided on both sides of the interior of the liquid outlet 5. Both sides of the movable sleeve 13 are connected to the guide grooves 14 through guide blocks, which guide and limit the plug 15 when it moves.

[0036] A fixing sleeve 16 is provided at the bottom of the liquid outlet 5, and the top of the dripper 7 is inserted and connected to the fixing sleeve 16;

[0037] Slide grooves 19 are provided on both sides of the interior of the fixing sleeve 16, and a socket 18 is provided on the fixing sleeve 16 at one end of the slide groove 19. Slide blocks 20 matching the slide grooves 19 are evenly provided on the outer side of the top of the dripper 7.

[0038] When the dripper 7 is installed with the fixing sleeve 16, the slider 20 is inserted into the fixing sleeve 16 through the socket 18. Then, the dripper 7 is rotated to make the slider 20 slide in the slide groove 19, thereby slidingly engaging the dripper 7 with the fixing sleeve 16, which facilitates the installation and removal of the dripper 7. In addition to controlling the space size of the flow channel 6 in the liquid outlet 5, the flow rate can also be adjusted by changing the specifications of the dripper 7.

[0039] The specific models and specifications of the first drive motor 3 and the second drive motor 11 need to be determined by selection calculation based on the specification parameters of the device. The selection calculation method is an existing technology and will not be described in detail.

[0040] Working principle: When the embodiment of the present application is in use, the height of the drip irrigation device body 1 can be adjusted by pulling the support rod 9 out of the sleeve 8 to a certain length and locking the screw hole 24 at the corresponding position through the fastener 25. The height position of the dripper 7 can be adjusted according to the planting position of the agricultural and forestry crops so that it is located above the soil of the agricultural and forestry crops. The nutrient solution is introduced into the drip irrigation device body 1 through the liquid inlet 2. The first drive motor 3 drives the rotating shaft 4 and the blades 22 to rotate to stir the nutrient solution evenly. The dripper 7 is connected to the bottom of the liquid outlet 5. The second drive motor 11 drives the screw rod 12 to rotate, so that the movable sleeve 13 moves along the screw rod 12, driving the plug 15 at one end of the movable sleeve 13 to adjust its position, thereby adjusting the flow inside the liquid outlet 5. The size of the space of the channel 6, the larger the internal space of the flow channel 6, the smaller the resistance when the nutrient solution passes through, and the greater the flow rate. The flow rate of the nutrient solution is controlled by controlling the position of the plug 15 inside the liquid outlet 5, which can be adjusted according to the type and growth stage of agricultural and forestry crops, so as to flexibly adjust the irrigation amount. In addition, a fixing sleeve 16 is provided at the bottom of the liquid outlet 5. When the dripper 7 and the fixing sleeve 16 are installed, the slider 20 is inserted into the fixing sleeve 16 through the socket 18, and then the dripper 7 is rotated to make the slider 20 slide in the slide groove 19, so that the dripper 7 and the fixing sleeve 16 are slidably engaged, which facilitates the installation and disassembly of the dripper 7. In addition to controlling the size of the space of the flow channel 6 in the liquid outlet 5, the flow rate can also be adjusted by replacing the specifications of the dripper 7.

[0041] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
