Description

Technical Field

[0001] This utility model relates to the field of fertilizer spraying technology, specifically to a device for all-round spraying of micronutrient fertilizers for economic crops. Background Technology

[0002] Cash crops, also known as "industrial raw material crops" or "technical crops," generally refer to crops that provide raw materials for industry, especially light industry. China has a wide variety of cash crops that are artificially cultivated, including fiber crops (such as cotton and hemp), oil crops (such as sesame and peanuts), sugar crops (such as sugarcane and sugar beets), three-ingredient crops (beverage, spice, and seasoning), medicinal crops, dye crops, ornamental crops, fruits, and other cash crops. In agricultural production, cash crops (such as fruits, vegetables, and tea) have a high demand for trace elements (such as iron, zinc, and boron). Reasonable supplementation of trace elements can significantly improve crop quality and yield.

[0003] Traditional fertilization methods mostly involve root application or foliar spraying. However, manual spraying or fixed nozzles make it difficult to achieve full and uniform coverage, which can easily lead to localized nutrient over- or under-nutrients in crops. Furthermore, the height and angle of the nozzles often depend on manual adjustment, which is inefficient and difficult to adapt to different crop heights and canopy structures. To address this, we propose a full-range micronutrient fertilizer spraying device for economic crops. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a comprehensive spraying device for micronutrient fertilizers for economic crops. This device achieves three-dimensional, all-around, uniform spraying through adjustable-height atomizing nozzles, adapting to different crop plant types. It is equipped with intelligent liquid level monitoring and mixing functions to ensure stable fertilizer concentration and prevent liquid interruption. The ergonomic design and electric control make operation convenient and labor-saving. Atomized spraying reduces waste, saves energy and is environmentally friendly, significantly improving fertilization efficiency and crop absorption rate. It is suitable for precision agricultural management and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an all-around spraying device for micronutrient fertilizers for economic crops, comprising a fertilizer tank and a battery;

[0006] Fertilizer liquid tank: Both ends of the left side are fixed with shoulder straps. The top surface of the fertilizer liquid tank is provided with an inlet pipe. The bottom surface of the inside of the fertilizer liquid tank is equipped with a liquid pump. The outlet of the liquid pump is connected to one end of the delivery pipe. The other end of the delivery pipe is connected to the inlet of the atomizing nozzle. The side of the fertilizer liquid tank is provided with an adjustment unit. The atomizing nozzle is installed inside the adjustment unit. The battery is fixed to the bottom surface of the fertilizer liquid tank.

[0007] It also includes a controller, which is fixed to the surface of the strap. The input end of the liquid pump is electrically connected to the output end of the controller, and the input end of the controller is electrically connected to the output end of the battery.

[0008] The liquid pump is activated to spray the fertilizer in the fertilizer tank into fine droplets through the atomizing nozzles onto the cash crops, supplementing them with trace elements and improving leaf adsorption efficiency while reducing waste.

[0009] Furthermore, the adjustment unit includes a rotating wheel, an adjustment seat, a screw, a mounting block, and a bracket. There are two adjustment seats, which are respectively fixed to the front and rear sides of the fertilizer liquid tank. A rotating wheel is fixed to the top surface of the adjustment seat. The bottom end of the rotating wheel is connected to the top end of the screw. The screw is threadedly connected to the screw hole on the surface of the mounting block. The interior of the adjustment seat is slidably fitted with the mounting block. A bracket is fixed to the end of the mounting block. Rotating the rotating wheel drives the screw to rotate to adjust the height of the bracket. At the same time, it can also be installed in a suitable direction according to the user's dominant hand for easy use, thereby improving the practicality of the device.

[0010] Furthermore, the adjustment unit also includes a lead screw, a fixed column, a rotating frame, a main motor, an extension rod, a support base, and an auxiliary motor.

The extension rod is slidably connected to the inside of the fixed column. The main motor is installed on the bottom surface of the fixed column. The output shaft of the main motor is connected to the bottom end of the lead screw. The lead screw is threadedly connected to the screw hole in the middle of the extension rod. The top end of the extension rod is provided with a support base. The auxiliary motor is fixed inside the support base. The output shaft of the auxiliary motor is connected to the middle of the bottom surface of the atomizing nozzle. The input ends of the main motor and the auxiliary motor are electrically connected to the output end of the controller. Starting the main motor drives the lead screw to rotate to adjust the extension length of the extension rod. With the auxiliary motor, the height, horizontal angle, and rotation angle of the atomizing nozzle can be adjusted in three dimensions to adapt to different crop plant heights and canopy morphologies, ensuring that the fertilizer solution evenly covers the front and back of the leaves and the stems.

[0011] Furthermore, the adjustment unit also includes a grip and a rubber sleeve. The grip is mounted on the top surface of the fixed column, and the rubber sleeve is fitted onto the outside of the grip. The grip, in conjunction with the carrying strap, is ergonomically designed to reduce the burden during carrying and adjustment, while the fitted rubber sleeve increases the comfort of the user's grip.

[0012] Furthermore, it also includes a liquid level sensor and an alarm. The liquid level sensor is fixed to the bottom of the right side of the fertilizer tank. There are two alarms, which are fixed to the front and rear sides of the fertilizer tank respectively. The output of the liquid level sensor is electrically connected to the input of the controller, and the input of the alarm is electrically connected to the output of the controller. The liquid level sensor monitors the remaining amount of fertilizer in the fertilizer tank in real time. When the remaining amount is low, the controller triggers the alarm to flash as a warning to avoid interruption of fertilizer spraying operations.
