Description

Technical Field

[0001] This utility model relates to the field of tobacco fertilization technology, specifically to an end-press type fertilization and topdressing device. Background Technology

[0002] Liquid fertilizers are necessary for tobacco cultivation primarily because they offer high nutrient solubility and rapid absorption, better meeting the nutrient needs of tobacco plants at different growth stages. During their vigorous growth period, tobacco requires significant amounts of nitrogen, phosphorus, and potassium, and liquid fertilizers can be quickly absorbed through the root system, improving fertilizer utilization efficiency. Furthermore, liquid fertilizers are easily integrated with irrigation, achieving fertigation, which effectively regulates soil moisture and nutrient distribution, preventing localized over- or under-nutrient deficiencies caused by uneven dissolution of solid fertilizers.

[0003] However, most existing liquid fertilizer application methods involve manual pouring or spraying, which cannot accurately deliver the liquid fertilizer to the tobacco roots. Furthermore, the amount of fertilizer sprayed is difficult to control, often resulting in over- or under-spraying, leading to fertilizer waste or inadequate application. In addition, this method requires workers to bend over for extended periods, which is not only physically demanding but also prone to causing fatigue and even injury to the workers.

[0026] In this embodiment, a plurality of protrusions 211 are formed on the outer surface of the second straight section 21 along its circumference. Each protrusion 211 is arranged along the axial direction of the second straight section 21. The protrusions 211 can provide better feel and friction, prevent slippage, and facilitate the installation and disassembly of the second cylinder 2 and the first cylinder 1.

[0027] In a specific implementation of this utility model, the abutting component 3 includes an abutting plate 31 and an abutting ring 32. The abutting plate 31 is threadedly connected to the inner wall of the second straight section 21 near the first conical section 12. A pair of opposing notches 301 are respectively opened on the abutting plate 31. The abutting ring 32 is disposed on the side surface of the abutting plate 31 away from the first conical section 12. The pressing component 4 abuts against the abutting ring 32.

[0028] In this embodiment, the abutting component 3 further includes a nut 33, which is disposed in the middle of one side of the abutting plate 31 near the first conical segment 12.

[0029] In the above technical solution, the function of the abutting component 3 is to provide a force point for the pressing component 4, that is, to abut against the limiting pressing component 4. The abutting component 3 is connected by the external thread of the abutting plate 31 and the internal thread of the inner wall of the second straight section 21.

[0034] The working principle of the end-press type fertilizer application and topdressing device provided by this utility model is as follows: When the pressure plate 41 is not subjected to external force, the elastic element 44 is in its original length state. At this time, the top plate 43 is interference-fitted to the inner wall of the third straight section 23, separating the cavity of the third straight section 23 from the cavity of the second conical section 22. The user removes the first cylinder 1 from the second cylinder 2 and injects sufficient liquid fertilizer into the first cavity 101. Then, the first cylinder 1 is reinstalled on the second cylinder 2, keeping the whole device in a vertical state.

[0035] When fertilization is required, unscrew the plug 13, place the device at the rootstock of the plant such as tobacco that needs fertilization, and press the device. The pressure plate 41 will drive the top plate 43 to move through the force transmission rod 42, and then the top plate 43 will be pushed into the second cone section 22. Since the second cone section 22 has a structure that is wider at the top and narrower at the bottom, the first straight section 11, the first cone section 12, the second straight section 21, the second cone section 22 and the third straight section 23 are connected at this time. The liquid fertilizer stored in the first straight section 11 flows into the second straight section 21 and the second cone section 22 through the gap 301, and then flows out to the rootstock of the plant through the third straight section 23.

[0036] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
