Description

Technical Field

[0001] The utility model relates to the technical field of agricultural spraying equipment, and more specifically, to a nozzle device for wheat breeding and cultivation spraying. Background Art

[0002] During the process of wheat breeding and cultivation, spraying is an important link for preventing and controlling pests and diseases and promoting growth. However, there are many deficiencies in the existing nozzle devices. The most prominent problem is that the spraying angle and range are fixed, making it difficult to flexibly adjust according to different growth stages and planting densities of wheat. Wheat has different spraying requirements at different growth stages. For example, at the seedling stage, the plants are short and dense, requiring a smaller spraying range and a specific spraying angle; while in the later growth stage, the plants are tall and sparse, requiring a larger spraying range and wider coverage. The existing nozzle devices with fixed spraying angles and ranges cannot meet these changing requirements, resulting in uneven spraying, waste of liquid medicine, and may also cause unnecessary impact on the plants, damaging the tender seedlings. Therefore, developing a nozzle device that can flexibly adjust the spraying angle and range is of great significance for improving the quality and efficiency of wheat breeding and cultivation.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0026] The following is further described in conjunction with specific embodiments. Referring to Figures 1-4 as shown, the present utility model is a nozzle device for spraying medicine in wheat breeding and cultivation. Referring to Figure 1 , it includes a nozzle body 10, a nozzle 20 and a control module.

[0027] Referring to Figure 1 and Figure 2 , the nozzle body 10 has a cylindrical structure and is internally provided with a liquid medicine channel 11 for conveying liquid medicine. One end of the nozzle body 10 is connected to a spraying pipeline through a quick-connect joint, which is convenient for installation and disassembly; the other end is connected to the nozzle 20. The nozzle body 10 is made of high-strength and corrosion-resistant aluminum alloy material, and its surface is treated by anodic oxidation, enhancing its wear resistance and corrosion resistance.

[0028] Referring to Figure 2 and 3, a spherical joint 21 is provided at the end of the nozzle 20. The spherical joint 21 is rotatably connected to the nozzle body 10. The nozzle 20 can freely adjust its angle in multiple directions through the spherical joint 21, and the adjustment range is 0° - 180°. A micro motor 18 is also provided on the nozzle body 10. In this embodiment, the micro motor 18 is a multi-degree-of-freedom spherical motor. The micro motor 18 is connected to the spherical joint 21 through a transmission mechanism, and is used to drive the spherical joint 21 to freely rotate in multiple directions. The transmission mechanism includes a micro gear set. The micro gear set 19 includes an input gear, an intermediate gear, and an output gear, and is used to transmit and amplify the rotational motion of the micro motor 18 to the spherical joint 21. Specifically, the input gear is installed on the output shaft of the micro motor 18 and is responsible for receiving the rotational power of the motor. The intermediate gear is meshed with both the input gear and the output gear. The intermediate gear is installed on the nozzle body and is used to change the direction and speed ratio of power transmission to ensure that the power can be efficiently transmitted to the output end. The output gear is installed on the periphery of the spherical joint 21, and the rotation axis of the output gear coincides with the drive shaft of the spherical joint 21. The output gear is used to connect with the intermediate gear and is connected to the drive shaft of the spherical joint 21, and is responsible for transmitting the power to the spherical joint 21. The control end of the micro motor 18 is electrically connected to the output end of the control module. Through the instructions of the control module, the micro motor 18 can precisely control the angle of the nozzle 20 to ensure the flexibility and accuracy of the spraying direction. For example, during the seedling stage of wheat, the nozzle 20 can be adjusted to a smaller angle for concentrated spraying; during the later growth stage of wheat, the nozzle 20 can be adjusted to a larger angle for wide coverage.

[0029] Referring to Figure 3 and Figure 4 , multiple tiny spray holes 22 are provided inside the nozzle 20, and each spray hole 22 is equipped with an independent micro solenoid valve 23. The control end of the micro solenoid valve 23 is electrically connected to the output end of the control module. The control module individually controls the opening and closing, spraying angle, and flow rate of each spray hole 22 according to the growth state of the wheat seedlings, so as to achieve precise spraying towards the wheat seedlings. In this embodiment, the nozzle 20 is used for spraying drugs in a large area of wheat planting area, so the volume of the nozzle 20 is relatively large. And the cover plate with the spray holes 22 on the nozzle 20 and the nozzle 20 body are of a detachable structure.

[0030] Referring to Figure 3 and Figure 4, inside the spray hole 22, there is also a micro-vortex generator 24. The function of the micro-vortex generator 24 is to generate tiny vortices to fully mix the liquid medicine before spraying, thereby improving the uniformity of spraying, ensuring that the liquid medicine can evenly cover the wheat plants, and enhancing the spraying effect. The structure of the micro-vortex generator 24 includes micro-vortex blades. The shape of the micro-vortex blades is triangular, and the length of the micro-vortex blades is 1 / 3 of the diameter of the spray hole 22. The tip of the micro-vortex blades should face the direction of liquid medicine flow, that is, the upstream direction. The micro-vortex blades generate vortices when the liquid medicine flows through the spray hole 22. The base of the micro-vortex blades and the micro-solenoid valve 23 are modularly encapsulated on the inner wall of the same cylinder. The middle part of the cylinder is hollow for the liquid medicine sprayed from the output end of the micro-solenoid valve 23. During installation, the cylinder is inserted into the spray hole 22, and the gap between the cylinder and the spray hole 22 is sealed to ensure that the liquid medicine can be fully mixed before spraying.

[0031] Refer to Figure 3 , the surface of the nozzle 20 is coated with a nano-coating 25, which can effectively prevent liquid medicine residue and impurity attachment, reduce the risk of clogging, extend the service life of the nozzle 20, and improve the reliability of the spraying device.

[0032] The control module is used to control the opening and closing of the micro-solenoid valve 23, thereby controlling the spraying state of each spray hole 22. The control module can flexibly adjust the spraying state of the spray holes 22 according to the growth stage of the wheat and the spraying requirements to achieve precise spraying.

[0033] Refer to Figure 2 , an environmental perception sensor 12 is arranged on the nozzle body 10 to monitor the environmental factors during the spraying process. In this embodiment, the environmental perception sensor 12 includes a wind speed sensor and a humidity sensor, which respectively monitor the wind speed data and air humidity data during the spraying process. The output end of the environmental perception sensor 12 is electrically connected to the input end of the control module to transmit the monitored environmental data to the control module. The control module automatically adjusts the spraying parameters according to the environmental data. When the wind speed is relatively high, the control module can adjust the angle of the nozzle 20 to reduce liquid medicine drift; when the humidity is relatively low, the liquid medicine flow rate can be increased to ensure that the liquid medicine can better adhere to the wheat plants.

[0034] Refer to Figure 2 , a high-precision flow sensor 13 is arranged in the liquid medicine channel 11. The output end of the flow sensor 13 is electrically connected to the input end of the control module. The flow sensor 13 can real-time monitor the liquid medicine flow rate in the liquid medicine channel 11 and transmit the data to the control module. The control module automatically adjusts the opening degree of the micro-solenoid valve 23 according to the flow data to achieve precise control of the liquid medicine flow rate and ensure the uniformity and precision of spraying.

[0035] Refer to Figure 2, a coarse filter screen 14, a fine filter membrane 15 and a filter element 16 are sequentially arranged in the liquid medicine channel 11. The aperture of the coarse filter screen 14 is 1 mm and it is used to filter large particle impurities; the aperture of the fine filter membrane 15 is 0.01 μm and it is used to filter fine suspended matters. The multi-stage filtering system can effectively prevent the nozzle from being blocked and ensure the cleanliness of the liquid medicine and the smoothness of spraying.

[0036] Refer to Figure 2 , a telescopic connecting rod 17 is adopted between the nozzle body 10 and the spraying pipeline, and the vertical position of the nozzle can be adjusted according to the height of the wheat to ensure the accuracy of the spraying height.

[0037] The working process of this embodiment is as follows: during the spraying process of wheat breeding and cultivation, the liquid medicine enters the liquid medicine channel 11 of the nozzle body 10 through the spraying pipeline, first passes through the multi-stage filtering system, and after removing impurities, enters the spray head 20. The micro solenoid valve 23 of the spray head 20 accurately controls the spraying state of each spray hole 22 according to the instructions of the control module. The user can adjust the angle, spraying range and spraying shape of the spray head 20 through the control module to ensure the accuracy of the spraying direction, range and shape. Through the high-precision flow sensor 13 and the micro solenoid valve 23, the liquid medicine flow is monitored and adjusted in real time to ensure the accuracy of spraying.

[0038] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
