Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a tobacco fertilization device. Background Technology

[0002] As an important economic crop, tobacco's planting and management techniques directly affect the yield and quality of tobacco leaves. Fertilization is a core element in tobacco cultivation, ensuring nutrient supply and promoting root development. Traditional fertilization methods typically involve manual application or the use of tools to assist in application. However, with the demands of modern large-scale agriculture, traditional fertilization methods are gradually revealing the following technical characteristics:

[0003] Tobacco fertilization is primarily done manually, with operators relying on experience to judge the amount of fertilizer and evenly distribute it to the crop root zone, resulting in low efficiency. With the advancement of mechanization, some growers have begun using simple fertilization devices, such as backpack electric fertilizer spreaders or hand-push trenching and fertilizing machines. While these devices improve operational efficiency, their core function remains primarily "ditching and covering," failing to address precise dosage control and targeted root application.

[0004] Larger fertilizer applicators are not suitable because the herbs grow quite tall and have large leaf areas. Furthermore, the main economic value of tobacco lies in its leaves. Larger fertilizer applicators cannot move between the rows and are likely to damage the tobacco plants. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a tobacco fertilization device, which aims to achieve integrated operation of hole opening, fertilization and resetting through mechanical structure innovation, significantly improve fertilization efficiency and accuracy, while reducing labor intensity and minimizing damage to tobacco.

[0006] This utility model provides a tobacco fertilization device, characterized in that it includes a lifting rod, a sliding sleeve provided on the outer side of the lower end of the lifting rod, the lifting rod being slidably disposed inside the sliding sleeve, a positioning plate fixedly disposed on the lower end of the sliding sleeve, a positioning hole provided on the positioning plate corresponding to the lower end of the lifting rod, a fixing sleeve fixedly disposed on the outer side of the lifting rod and above the sliding sleeve, a foot pedal fixedly disposed on one side of the fixing sleeve, a spring disposed on the lower end of the sliding sleeve and outside the lifting rod, the lower end of the spring being fixedly disposed on the sliding sleeve, a pointed corner fixedly disposed at the bottom of the lifting rod, a fertilizer box fixedly disposed on the front side of the sliding sleeve, a metering feeding wheel rotatably disposed at the bottom of the fertilizer box, a material trough disposed on the metering feeding wheel, and a linkage mechanism hinged to the lower side of the foot pedal, the linkage mechanism being connected to the metering feeding wheel.

[0007] In a preferred embodiment, a wheel bracket is fixedly provided on the rear side of the sliding sleeve, and a movable wheel is provided at the bottom of the wheel bracket.

[0008] In a preferred embodiment, the bottom of the positioning plate is higher than the bottom of the moving wheel.

[0009] In a preferred embodiment, a handrail is fixedly provided at the upper end of the lifting rod.

[0010] In a preferred embodiment, a discharge trough plate is provided on the front side of the sliding sleeve and below the quantitative feeding wheel, and a triangular storage trough is provided on the inner side of the discharge trough plate, with the bottom inner side of the triangular storage trough attached to the outer wall of the lifting rod.

[0011] In a preferred embodiment, a fixing plate is fixedly provided on the side of the fixing sleeve away from the pedal, a guide rod is fixedly provided on the fixing plate, a guide plate is fixedly provided on the outer side of the sliding sleeve corresponding to the position of the guide rod, a guide hole is provided on the guide plate, and the guide rod is slidably disposed in the guide hole.

[0012] In a preferred embodiment, the linkage mechanism includes a connecting rod hinged to the pedal, a handle hinged to the lower side of the connecting rod, and the end of the handle away from the connecting rod fixed to the axle of the metering wheel.

[0013] In a preferred embodiment, the fertilizer box is provided with a lid on its upper side.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Precise and quantitative fertilization improves fertilizer utilization. The coordinated design of the quantitative feeding wheel and triangular storage trough enables precise 180° rotation and feeding in a single operation. The trough volume is fixed, while the adjustable pressing depth of the lifting rod allows for flexible control of the amount of fertilizer applied per application based on the tobacco growth cycle, avoiding the problems of over- or under-fertilization associated with traditional hand-spreading methods and significantly improving fertilizer utilization.

[0016] Mechanized hole-digging and fertilization are integrated, improving work efficiency. The soil breaking and hole-digging and fertilizer application are completed simultaneously when the soil is pressed down. The spring reset mechanism makes the lifting rod automatically rebound, and the fertilizer slides into the hole along the rod. The single operation cycle is shortened to 2-3 seconds, which is more than 3 times more efficient than traditional manual hole digging and fertilization.

[0017] The device is highly adaptable to ridge cultivation and ensures accurate fertilization positioning. The height difference design between the moving wheels and the positioning plate (the bottom of the positioning plate is higher than the moving wheels) allows the device to move stably along the furrows while ensuring that the fertilization point is accurately positioned at the top of the ridge and the tobacco roots.

[0018] The foot-operated drive mechanism, which uses a linkage lever principle, converts vertical downward pressure into the rotational motion of a metering feed wheel, reducing labor intensity and simplifying operation. Operators only need to lightly press the pedal to complete the entire process of opening holes, feeding materials, and resetting, significantly reducing labor intensity compared to the traditional method of digging holes and applying fertilizer with a hoe.

[0019] The optimized structural design enhances the equipment's durability. Its compact and lightweight design makes it suitable for complex field conditions and minimizes damage to tobacco plants during walking and fertilization. Attached Figure Description
