Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] To further understand the contents of the utility model, the utility model will be described in detail in conjunction with the drawings.

[0024] In conjunction with Figures 1-5The application discloses a precise feeding and proportioning structure of an intelligent water and fertilizer integrated machine, which comprises a double-cylinder supporting structure 1, a water storage barrel 2 and a fertilizer barrel 3 arranged on the double-cylinder supporting structure 1 respectively, and the water storage barrel 2 and the fertilizer barrel 3 are communicated with a mixing box 4 at bottom ends, a feeding pipe is connected with external material conveying and water conveying equipment, and a pipeline is communicated with external output equipment, so that the mixing and output of water and fertilizer can be realized, and the intelligent control of the fertilization and irrigation process is facilitated. The water storage barrel 2 and the fertilizer barrel 3 are composed of a first cylinder 21, a second cylinder 22 and a volume adjusting assembly 5, through cooperation of the volume adjusting assembly 5 and a driving assembly 6, the volume of the water storage barrel 2 and the fertilizer barrel 3 can be accurately adjusted, then the feeding amount can be accurately controlled, the accuracy of water and fertilizer proportioning is ensured, and the specific requirements of different crops and different growth stages on water and fertilizer are met. A feeding end of an active cylinder 51 is slidably connected to an inner wall of the first cylinder 21, and a discharging end is threadedly connected with the second cylinder 22, so that the position of the active cylinder 51 in the cylinder can be adjusted to change the volume, and the stability of the connection is ensured. An electromagnetic valve 54 is arranged at an end of a discharging funnel 53, so that the discharging time and the discharging amount of the material can be accurately controlled, and the accuracy of feeding is further improved. A material stirring plate 55 is rotatably connected to the inner wall of the feeding end of the active cylinder 51, so that the material can be stirred during the feeding process, the material is prevented from being caked or blocked in the feeding port, and the feeding process is ensured to be smooth.

[0025] The double-cylinder supporting structure 1 is composed of two hoop cylinder rings 11, two arc-shaped plates 12, two connecting plates 13 and a double-cylinder groove base 14, the hoop cylinder ring 11 is fixedly connected with the outer wall of the first cylinder 21, and the double-cylinder groove base 14 is movably connected with the outer wall of the second cylinder 22. The combination mode provides stable support for the whole device, and ensures the stability and reliability of the components during the operation process. Meanwhile, the device is facilitated to be installed and maintained.

[0026] The laser liquid level sensor 211 is symmetrically fixedly installed on the inner wall of the top end of the first cylinder 21. The laser liquid level sensor 211 can monitor the liquid level height of the material in the first cylinder in real time and accurately, provides key data support for accurate control of feeding, and is helpful to optimize the feeding proportioning.

[0027] The stepper motor 61 in the driving assembly 6 is fixedly installed at the top end of the connecting plate 13, is stable in position, can provide a stable and reliable power source for the entire driving system, and ensures the continuity and stability of operation. The main tooth roller 62 fixedly connected to the output shaft of the stepper motor 61 is efficient and accurate in transmission, and can effectively transmit the power of the motor to the subsequent transmission components. The main tooth roller 62 is meshed with the second tooth ring 621 on one side and the slave tooth roller 63 on the other side. This structure design makes the transmission process flexible and controllable, and can be accurately adjusted according to actual needs. The slave tooth roller 63 is meshed with the third tooth ring 631 on the other side, which further increases the diversity and flexibility of transmission and meets the complex motion control requirements. Since the number of teeth of the second tooth ring 621 and the third tooth ring 631 is different, they are fixed on the movable cylinder 51 of the water storage barrel 2 and the fertilizer barrel 3 respectively, so that the differential motion of the two can be realized, thereby accurately and flexibly adjusting the discharge ratio of the water storage barrel and the fertilizer barrel to meet different matching requirements. The main tooth roller 62 and the slave tooth roller 63 are rotatably arranged between the two connecting plates 13, which ensures the stability and reliability during operation, reduces the transmission error caused by shaking or deviation, and improves the working precision and efficiency of the entire system.

[0028] The size and number of teeth of the main tooth roller 62 and the slave tooth roller 63 are different. This difference in design helps to achieve different transmission ratios, thereby more accurately controlling the feeding speed and ratio of the water storage barrel and the fertilizer barrel, and improving the applicability and flexibility of the device.

[0029] The bottom end of one of the connecting plates 13 is fixedly installed with the stirring motor 7 in the groove of the middle part of the double-cylinder groove base 14, the output end of the stirring motor 7 is fixedly connected with the stirring rod 71, and the stirring rod 71 extends into the inside of the mixing box 4. The arrangement of the stirring motor 7 and the stirring rod 71 can ensure that the materials in the mixing box are fully mixed, improve the uniformity of water and fertilizer mixing, and provide better nutrient supply for crops.

[0030] Working principle: When the intelligent water and fertilizer integrated machine is running, the external material conveying and water conveying equipment respectively convey materials to the water storage barrel 2 and the fertilizer barrel 3. The laser liquid level sensor 211 monitors the liquid level in the one-section cylinder 21 in real time. The stepper motor 61 in the driving assembly 6 starts to drive the main tooth roller 62 to rotate, the main tooth roller 62 is meshed with the second tooth ring 621 on one side and the slave tooth roller 63 on the other side, and the slave tooth roller 63 is meshed with the third tooth ring 631. Because the size and number of teeth of the main tooth roller 62 and the slave tooth roller 63 are different, the rotating speeds of the second tooth ring 621 and the third tooth ring 631 are different, thereby driving the movable cylinder 51 to move at different speeds in the one-section cylinder 21 and the two-section cylinder 22, realizing differential volume adjustment of the water storage barrel 2 and the fertilizer barrel 3. Finally, the materials enter the mixing box 4 through the discharge funnel 53 and the electromagnetic valve 54 for stirring and mixing. Through the clever cooperation of the movable cylinder 51 and various components in the volume adjustment assembly 5, the amount of feeding can be accurately controlled to meet different matching requirements.
