Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and more specifically, to a high-efficiency self-scattering fertilizer spreader. Background Art

[0002] The source of modern human food depends on agricultural production as the primary industry. However, due to the growth of the world's population, it is impossible to produce enough food to meet human needs by relying solely on the basic fertility of the soil. Therefore, we must apply a large amount of fertilizer in agricultural production. In addition to the limited organic fertilizers that nature can provide, we currently rely more on chemical fertilizers.

[0003] Fertilizer is a necessary material for the growth of crops. Fertilizers such as microbial fertilizers are also called bacterial agents or bacterial fertilizers, which are mainly composed of beneficial microorganisms, organic carriers, inorganic fertilizers, etc. In recent years, microbial fertilizers have attracted much attention due to their great advantages in promoting crop growth, improving crop resistance to disease and stress, and increasing soil fertility, thus meeting the needs of agricultural planting.

[0004] Existing fertilization treatment for microbial fertilizers, organic fertilizers, etc. is usually carried out manually. The manual fertilizer spreading method has the following problems:

[0005] 1. It requires a lot of manpower and material resources, and the fertilization effect is poor and the efficiency is low;

[0006] 2. The amount of fertilizer applied cannot be well controlled, resulting in uneven fertilizer application and uneven growth of crops in the later stage;

[0007] 3. Fertilizers are harmful to the human body. Therefore, in addition to taking precautions when applying them manually, such as wearing protective equipment such as masks and gloves, which is time-consuming and labor-intensive, fertilizer applicators are also required to have a certain level of protection awareness.

[0008] 4. Fertilizers tend to clump, resulting in poor fluidity and uneven fertilization. Summary of the invention

[0009] The present invention provides a high-efficiency self-spreading fertilizer spreader to solve the problem that most fertilizer spreaders in the prior art need to use other machinery or manpower to transfer fertilizer to the spreader. For small-scale farmers, manual transfer is usually adopted, which is time-consuming and labor-intensive, and cannot solve the problem of fertilizer agglomeration and uneven fertilization, thereby reducing the fertilization efficiency and the practicality of the device.

[0010] To achieve the above object, the present invention provides the following technical solutions.

[0011] A high-efficiency self-scattering fertilizer spreader, characterized in that it includes a fuel tricycle, the fuel tricycle includes a bottom plate with a horizontal top surface, two mutually parallel longitudinal brackets are longitudinally arranged on the bottom plate, and a hopper is connected to the two longitudinal brackets; a battery, a first rotating shaft, a second rotating shaft, a bumpy dustpan, and a fan are arranged on the bottom plate; a rectangular fertilizer outlet is arranged at the rear lower part of the hopper, and the long side of the fertilizer outlet is arranged horizontally.

[0012] The hopper comprises a left arm and a right arm. A first rotating shaft is transversely installed between the left arm of the hopper near the fertilizer outlet and the right arm near the fertilizer outlet. A feeding roller is coaxially installed on the first rotating shaft. A plurality of feeding grooves are transversely arranged on the radial outer peripheral surface of the feeding roller. The feeding roller is located in the fertilizer outlet and can seal the fertilizer outlet. The first rotating shaft is connected to the driving system of the walking mechanism.
