Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery equipment, and in particular to a device for irrigating and fertilizing crops. Background Art

[0002] The development of fertigation devices has gone through an evolution from simple to complex, from traditional to modern. In ancient times, people mainly used natural water sources such as rivers and canals for irrigation. With the development of human civilization, irrigation technology has gradually improved. At present, the global agricultural field is ushering in a period of transformation and upgrading driven by science and technology. The intelligence and precision of fertigation devices have become an important symbol of agricultural modernization. With the continuous development of the rural economy and the improvement of farmers' income levels, farmers' demand for efficient, energy-saving and environmentally friendly agricultural machinery and equipment is increasing.

[0003] Although some existing fertigation devices can achieve fertigation operations to a certain extent, due to their unreasonable structural design, uneven mixing of water and fertilizer may occur. For example, patent document CN221043768U discloses an fertigation device, which adopts a technical solution of directly mixing water and fertilizer in batches. However, when a large amount of fertilizer is directly added to water, it may be difficult for water and fertilizer to be fully mixed due to excessive fertilizer.

[0004] In summary, the problem of uneven water-fertilizer mixing in some existing fertigation devices has become a difficult problem that needs to be solved urgently in the art. Therefore, it is necessary to propose a fertigation device for crops. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a device for irrigation and fertilization of crops. Through the precise operation of the discharge component, the release amount and release speed of the fertilizer can be accurately controlled to meet the fertilization needs of different crops and different growth stages. At the same time, the setting of the mixing component enables water and fertilizer to be fully mixed inside the device to form a uniform water-fertilizer mixed solution, so that it can be better absorbed and utilized by crops, thereby promoting the healthy growth of crops.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a device for irrigation and fertilization of crops, comprising a controller and a shell, wherein a support frame is symmetrically fixedly connected to the bottom of the shell, and a plurality of universal wheels are rotatably connected to the support frame; a fertilizer storage box is fixedly connected to the top of the shell, the fertilizer storage box is filled with fertilizer, the fertilizer storage box is connected to the inside of the shell, and a plurality of atomizing nozzles are connected to the bottom of the shell.

[0007] A driving member is fixedly connected to the top wall of the housing, and the controller is used to control the rotation of an output shaft of the driving member.

[0008] The output shaft of the driving member is coaxially and fixedly connected to a rotating rod, and a rotating frame is fixedly connected to the rotating rod. A feeding component for releasing fertilizer is provided on one side of the rotating frame.

[0009] A mixing component for realizing the mixing of water and fertilizer is provided below the rotating frame.

[0010] The technical principle of the above solution is as follows:

[0011] The staff adds water and fertilizer into the outer shell and the fertilizer storage tank respectively, and controls the driving member to start through the controller. The output shaft of the driving member rotates, driving the rotating rod to rotate, and the rotating rod drives the feeding component and the mixing component to operate.

[0012] During the operation of the feeding component, the fertilizer is released downward, and the mixing component performs the operation of mixing the fertilizer and water inside the outer shell to obtain a water-fertilizer mixed solution.

[0013] During this process, the staff controls the feeding component through the controller to control the discharge amount of the fertilizer.

[0014] After the water-fertilizer mixing is completed, the water-fertilizer mixed solution enters the atomizing nozzle and irrigates and fertilizes the crops below in the form of spray.

[0015] The above solution has the following beneficial effects:

[0016] 1. In the present invention, through the precise operation of the feeding component, the release amount and release speed of the fertilizer can be accurately controlled, meeting the fertilization requirements of different crops and different growth stages. At the same time, the setting of the mixing component enables the water and fertilizer to be fully mixed inside the device to form a uniform water-fertilizer mixed solution, which can be better absorbed and utilized by the crops, promoting the healthy growth of the crops.

[0017] 2. In the present invention, the support frame and universal wheels provided at the bottom of the device enable the entire device to move easily in the farmland, greatly improving the flexibility and efficiency of fertilization and irrigation.

[0018] 3. In the present invention, through the precise control of the mixing component, the water-fertilizer ratio can be adjusted according to the actual needs of the crops, realizing a customized fertilization and irrigation plan.

[0019] Furthermore, the feeding component includes a support rod fixedly connected to the inner top wall of the outer shell. The bottom of the support rod is rotatably fitted with a rotating disk, and the rotating disk is located in the movement path of the rotating frame.

[0020] A plurality of first solenoid valves are communicated with the rotating disk. The controller is used to control the opening and closing of the first solenoid valves. A feeding cylinder is fixedly connected to the inner top wall of the outer shell, and the fertilizer storage tank is communicated with the first solenoid valves through the feeding cylinder.

[0021] An extension rod is fixedly connected to the side wall of the rotating rod. A gear is rotatably fitted to one end of the extension rod away from the rotating rod. A toothed ring is fixedly connected to the inner side wall of the housing. The gear meshes with the toothed ring. A coaxial extension shaft is fixedly connected to the top of the gear. The top of the extension shaft penetrates through the extension rod and is fixedly connected to a limiting rod. A limiting shaft is fixedly connected to one end of the limiting rod away from the extension rod. A plurality of limiting blocks are fixedly connected to the bottom circumference of the rotating disc. Limiting grooves are formed in the limiting blocks. The limiting shaft and the limiting grooves are slidably fitted.

[0022] Beneficial effects: By precisely controlling the opening and closing of the first solenoid valve through the controller, precise control of the fertilizer release amount, release speed, and release time can be achieved, thereby precisely adjusting the water-fertilizer ratio. At the same time, the meshing design of the gear and the toothed ring, as well as the sliding fit between the limiting shaft and the limiting groove, enhance the stability and reliability of the device, making the rotating disc less likely to shake or get stuck during rotation, thus ensuring the smooth progress of the water-fertilizer mixing process.

[0023] Further, the mixing assembly includes stirring blades fixedly connected to the bottom circumference of the rotating rod.

[0024] Beneficial effects: The stirring blades can achieve uniform mixing of water and fertilizer during the stirring process, so it can ensure the full utilization of fertilizer during irrigation. Compared with the situation where fertilizer is easily lost or wasted in traditional fertilization methods, it can greatly improve the fertilizer utilization rate.

[0025] Further, a brush is fixedly connected to the bottom of the stirring blade.

[0026] Beneficial effects: The brush design at the bottom of the stirring blade enables the brush to have more sufficient contact and friction with the fertilizer particles and water in the water-fertilizer mixture during the stirring process. This contact and friction not only help accelerate the dissolution and dispersion of the fertilizer but also promote more uniform mixing of the components in the water-fertilizer mixture. At the same time, it can also clean the inner bottom wall of the housing during the stirring process, reducing the possibility of the atomizing nozzle being blocked.

[0027] Further, second solenoid valves are connected to the communication parts between the housing and the atomizing nozzles. The controller is used to control the opening and closing of the second solenoid valves.

[0028] Beneficial effects: The design of the second solenoid valves enables the controller to precisely control the opening and closing of the atomizing nozzles, making the irrigation and fertilization process more refined. According to factors such as the actual needs of the crops, growth stages, and soil humidity, the irrigation and fertilization amount and frequency of the atomizing nozzles can be flexibly adjusted. This precise control helps improve the fertilizer utilization rate, reduce waste, and promote the healthy growth of the crops.

[0029] Further, a handle is fixedly connected to the side wall of the housing.

[0030] Advantageous effects: The design of the handle enables users to easily move the entire irrigation and fertilization device.

[0031] Furthermore, a fertilizer storage hole is opened at the top of the fertilizer storage tank, and a first rotary cover is detachably connected to the fertilizer storage hole.

[0032] Advantageous effects: When the fertilizer reserve in the fertilizer storage tank is insufficient, the staff can add fertilizer through the fertilizer storage hole. At the same time, the design of the first rotary cover can effectively prevent the volatilization and leakage of fertilizer during storage, further reducing waste.

[0033] Furthermore, a water inlet hole is opened at the top of the outer shell, and a second rotary cover is detachably connected to the water inlet hole.

[0034] Advantageous effects: The detachability of the second rotary cover enables users to easily open the water inlet hole, thus facilitating the addition of water.

[0035] Furthermore, sealing rings are fixedly connected to both the first rotary cover and the second rotary cover.

[0036] Advantageous effects: The tight fit of the sealing rings effectively prevents external impurities and pollutants from entering the fertilizer storage tank and the interior of the outer shell, ensuring the purity of the fertilizer and water, and reducing the risk of crop growth hindrance caused by pollution.

[0037] Furthermore, a solar panel is fixedly connected to the top of the outer shell.

[0038] Advantageous effects: The solar panel can directly convert solar energy into electrical energy to provide power for the irrigation and fertilization device.

[0039] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0045] The following is a further detailed description through specific implementation manners:

[0046] Embodiment 1:

[0047] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 : A device for irrigating and fertilizing crops includes a controller and a housing 1. A handle 2 is welded to the side wall of the housing 1, and support frames 3 are symmetrically welded to the bottom of the housing 1. A number of universal wheels 4 are rotatably connected to the support frames 3; A fertilizer storage tank 5 is integrally formed on the top of the housing 1. Fertilizer is filled in the fertilizer storage tank 5. The fertilizer storage tank 5 is communicated with the inside of the housing 1, and a number of atomizing nozzles 6 are communicated with the bottom of the housing 1.

[0048] A fertilizer storage hole is opened at the top of the fertilizer storage tank 5, and a first rotary cover 7 is detachably connected by threads at the fertilizer storage hole; An inlet hole is opened at the top of the housing 1, and a second rotary cover 8 is detachably connected by threads at the inlet hole. Sealing rings are fixedly adhered to both the first rotary cover 7 and the second rotary cover 8.

[0049] A driving member is fixedly connected to the inner top wall of the housing 1 by bolts, and the controller is used to control the rotation of the output shaft of the driving member. In this embodiment, the driving member is a stepper motor.

[0050] The output shaft of the stepper motor is coaxially and fixedly connected to a rotating rod 9 by bolts. A rotating frame 10 is welded to the rotating rod 9. A discharging assembly for releasing fertilizer is arranged on one side of the rotating frame 10, and a mixing assembly for realizing the mixing of water and fertilizer is arranged below the rotating frame 10.

[0051] The discharging assembly includes a support rod 11 welded to the inner top wall of the housing 1. The bottom of the support rod 11 is rotatably fitted with a rotating disk 12, and the rotating disk 12 is located in the movement path of the rotating frame 10.

[0052] A number of first solenoid valves 13 are communicated with the rotating disk 12. The controller is used to control the opening and closing of the first solenoid valves 13. A discharging cylinder 14 is welded to the inner top wall of the housing 1. The fertilizer storage tank 5 is communicated with the first solenoid valves 13 through the discharging cylinder 14.

[0053] A second electromagnetic valve is connected to the connection between the outer shell 1 and the atomizing nozzle 6, and the controller is used to control the opening and closing of the second electromagnetic valve.

[0054] An extension rod 15 is welded to the side wall of the rotating rod 9. One end of the extension rod 15 away from the rotating rod 9 is rotatably fitted with a gear 16. A toothed ring 17 is welded to the inner side wall of the outer shell 1, and the gear 16 meshes with the toothed ring 17; a coaxial extension shaft is fixedly connected to the top of the gear 16. The top of the extension shaft penetrates through the extension rod 15 and is fixedly connected with a limiting rod. One end of the limiting rod away from the extension rod 15 is fixedly connected with a limiting shaft 18. A plurality of limiting blocks 19 are integrally formed in the circumferential direction at the bottom of the rotating disc 12. Limiting grooves are formed in the limiting blocks 19, and the limiting shaft 18 is slidably fitted with the limiting grooves.

[0055] The mixing assembly includes stirring blades 20 welded to the bottom of the rotating rod 9 in the circumferential direction, and a brush 21 is integrally formed at the bottom of the stirring blade 20.

[0056] The specific implementation process is as follows: The staff unscrews the first screw cap 7 and the second screw cap 8, and adds fertilizer and water into the fertilizer storage tank 5 and the inner part of the outer shell 1 respectively through the fertilizer storage hole and the water inlet hole. After the addition is completed, the first screw cap 7 and the second screw cap 8 are screwed tightly.

[0057] The staff starts the stepper motor through the controller and controls the first electromagnetic valves 13 to remain open and the second electromagnetic valves to remain closed. The output shaft of the stepper motor rotates, driving the rotating rod 9 to rotate. During the rotation of the rotating rod 9, the extension rod 15 and the rotating frame 10 are driven to rotate. The extension rod 15 drives the gear 16 to revolve.

[0058] During the revolution of the gear 16, it rotates self-driven under the meshing action with the toothed ring 17, driving the extension shaft to rotate. The extension shaft drives the limiting rod to rotate, and the limiting rod drives the limiting shaft 18 to rotate, so that it rotates into the limiting groove. During the continuous rotation, the rotating disc 12 is pushed to rotate.

[0059] The rotating disc 12 rotates driven by the rotating frame 10 and the limiting shaft 18, driving the first electromagnetic valve 13 to rotate. When the first electromagnetic valve 13 rotates below the material discharging cylinder 14, the fertilizer in the fertilizer storage tank 5 is discharged into the inner part of the outer shell 1 through the material discharging cylinder 14.

[0060] During the rotation of the rotating rod 9, the stirring blades 20 are also driven to rotate, mixing the water and fertilizer inside the outer shell 1 to carry out water-fertilizer mixing and obtain a water-fertilizer mixed solution.

[0061] After the water-fertilizer mixing is completed, the controller controls the second electromagnetic valve to open, and the water-fertilizer mixed solution enters the atomizing nozzle 6 through the second electromagnetic valve, and irrigates and fertilizes the crops below in the form of spraying.

[0062] During the rotation of the stirring blade 20, the brush 21 thereon will also rotate to clean the inner bottom wall of the housing 1, reducing the situation of the second solenoid valve being blocked, and thus making the irrigation and fertilization device operate more smoothly.

[0063] During the process of putting the fertilizer into the interior of the housing 1, the staff can control the amount of fertilizer released by controlling the opening and closing of the first solenoid valve 13. For example, during the process of mixing water and fertilizer, when the proportion of the fertilizer is relatively large, the staff fully opens the first solenoid valve 13; when the proportion of the fertilizer is moderate, the staff closes half of the number of the first solenoid valves 13, so as to control the amount of fertilizer released.

[0064] By precisely controlling the release amount and release speed of the fertilizer to meet the fertilization requirements of different crops and different growth stages. At the same time, through the stirring blade 20 and the brush 21, the water and the fertilizer can be fully mixed inside the irrigation and fertilization device to form a uniform water-fertilizer mixed solution, so that it can be better absorbed and utilized by the crops, promoting the healthy growth of the crops.

[0065] Embodiment 2:

[0066] As shown in the attached Figure 1 and Figure 3 figure, the difference from Embodiment 1 is that a solar panel 22 is fixedly connected to the top of the housing 1 by screws.

[0067] The specific implementation process is as follows: During the operation of the irrigation and fertilization device, the solar panel 22 can convert solar energy into electrical energy to provide energy for itself, reducing the consumption of traditional electrical energy.

[0068] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
