Description

Technical Field

[0001] The invention relates to the technical field of tobacco fertilization equipment, in particular to a tobacco fertilizer applicator with a hole-fertilization and strip-fertilization dual-mode switch and variable hole distance and application amount. Background Art

[0002] As an important economic crop, the fertilization process in the tobacco planting process has a critical impact on the yield and quality of tobacco. With the advancement of agricultural modernization, tobacco field fertilizer spreaders have emerged to improve fertilization efficiency, reduce labor costs and achieve precise fertilization. However, there are still many shortcomings in the tobacco field fertilizer spreaders on the market, which to some extent limit their wider application and better operation results.

[0003] In tobacco field fertilization operations, evenly distributing fertilizers in the planting area is an important prerequisite for ensuring the consistency of growth of each tobacco plant. Many existing tobacco field fertilizer spreaders cannot accurately control the flow and landing point of fertilizers during fertilizer transportation and spreading due to the limitations of mechanical structure design. For example, some tobacco field fertilizer spreaders use simple spiral conveying devices. Under different rotation speeds and material accumulation conditions, the output of fertilizers will fluctuate greatly, resulting in too much fertilizer in some areas and too little fertilizer in other areas when fertilizing in the field. This not only affects the balanced absorption of nutrients by tobacco plants, causing some tobacco plants to grow too vigorously or develop poorly, but may also cause seedling burns due to excessive local fertilizer concentrations, seriously damaging the benefits of tobacco planting.

[0004] Southwest China is one of the important tobacco-growing regions in my country. However, spring drought has long plagued tobacco agricultural production in the region. In spring, the southwest region often has little precipitation, rapid temperature rises, high evaporation, and rapid loss of soil moisture, resulting in a serious lack of soil moisture in tobacco fields. This drought condition has an extremely adverse impact on tobacco sowing, seedling cultivation, and early growth and development, and is one of the key factors restricting the improvement of tobacco leaf yield and quality in the southwestern tobacco region.

[0005] Traditional measures to deal with spring drought have many limitations in practical application. For example, although artificial irrigation can directly replenish soil moisture, when implemented in large areas of tobacco fields, it faces problems such as water shortage, imperfect irrigation facilities and high labor costs. Moreover, it is difficult to maintain suitable soil moisture for a long time by relying solely on irrigation, as water can easily seep in quickly or evaporate and dissipate.

[0006] As a functional material that can effectively improve the water retention capacity of the soil, water retaining agent has been used in the agricultural field to a certain extent. It can absorb and store a large amount of water, and slowly release it when the soil is dry, thereby continuously supplying water for crop growth. However, the existing water retaining agent application methods are mostly manual broadcasting or simple mixing and application, which has the defects of uneven application amount, loose combination with fertilizer, and low operation efficiency. In the case of large-scale tobacco fields in the spring drought areas in the southwest, these traditional application methods are difficult to meet the needs of efficient and precision agricultural production.

[0007] With the advancement of agricultural modernization, the advantages of mechanized operations in agricultural production are becoming increasingly prominent. However, there is currently almost no machinery for applying water retainers mixed with fertilizers in tobacco fields in the southwestern spring drought area. Factors such as the soil texture, topography, and special requirements for the mixed application of water retainers and fertilizers in tobacco fields make it impossible for general agricultural machinery to be directly applied to this scenario.

Through the meshing transmission of the swing angle drive gear 58 and the swing angle transmission gear 55, the swing angle transmission gear 55 drives the outer sleeve 511 to rotate around its own axis, and then drives the transverse conveying pipe 52 to swing, so as to achieve row spacing adjustment; during the adjustment process, the swing angle adjustment drive motor 57 and the swing angle drive gear 58 revolve together around the axis of the outer sleeve 511 on the fixed plate 56.
