Description

Technical Field

[0001] The invention relates to the technical field of tea garden planting, and more specifically to a fertilizing device for fertilizing a tea garden. Background Art

[0002] The fertilization device is one of the fertilization equipment used for tea garden planting. Among them, the common fertilization device is mainly composed of a fertilizer box, a fertilizer delivery mechanism, a fertilizer applicator, a furrow opener, a soil cover, a transmission mechanism, and a control system. The specific process of the fertilization device for tea garden planting is as follows: Fertilizer supply: First, add fertilizer to the fertilizer box to ensure that the fertilization device has sufficient fertilizer supply; Fertilizer delivery: The fertilizer is transported from the fertilizer box to the fertilization point through the fertilizer delivery mechanism. In this process, the flow and speed of the fertilizer can be adjusted as needed; Fertilization operation: After arriving at the fertilization point, the fertilizer applicator applies the fertilizer into the soil or near the root system of the crop in an appropriate manner. The specific fertilization method depends on the type of fertilizer applicator and the growth requirements of the crop; Soil treatment: For devices that require furrowing and fertilization, the furrow opener will open a furrow of a certain depth and width in the soil; After fertilization, the soil cover will cover the furrow with soil; Intelligent control: The intelligent control system will automatically adjust the amount of fertilizer, fertilization time and fertilization method according to the preset parameters and real-time monitoring data to achieve precise fertilization and efficient use of resources;

[0003] Among them, common fertilizers will clump when being transported to the fertilizer box because they have been stacked in the fertilizer box for too long or the fertilizer particle size is uneven and the particle compressive strength is low, resulting in the following situations: 1. Impact on the fertilizer itself: After the fertilizer is agglomerated, the contact area between its particles increases, and physical and chemical reactions are prone to occur, which causes changes in the nutritional components of the fertilizer, thereby reducing the quality of the fertilizer; 2. Impact on the effect of the fertilizer: After the fertilizer is agglomerated, it is difficult to be fully absorbed by the crop roots, resulting in the inability to fully release the nutrients in the fertilizer, thereby reducing the fertilizer effect. In addition, lumped fertilizers may also hinder root growth due to their large particles, further affecting nutrient absorption; as mentioned above, when fertilizers are lumpy, they become ineffective, leading to certain economic losses. At the same time, if the fertilizer residues in the fertilizer box are not cleaned up in time after fertilization, the quality of the fertilizer will be affected. The reasons for this are: the fertilizers left in the fertilizer box are easily affected by moisture, lumps or deterioration, which not only reduces the fertilizer efficiency, but also may produce harmful substances, causing damage to crops that are subsequently fertilized. In addition, the residual fertilizers may also become a breeding ground for pathogens and pests, further affecting the health of crops, thus causing certain economic losses. Summary of the invention

[0004] In order to overcome the above defects of the prior art, the present invention provides a fertilizing device for fertilizing a tea garden to solve the problems existing in the above background technology.
