Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a fertilizer spreader with single-power combined transmission. Background Art

[0002] In agricultural production, fertilization is one of the key links to improve crop yield and quality. Traditional fertilization methods include manual fertilization and simple mechanical fertilization. Manual fertilization is inefficient, labor-intensive, and difficult to ensure uniformity of fertilization, which cannot meet the needs of large-scale agricultural planting.

[0003] Although traditional mechanical fertilizer spreaders have improved the fertilization efficiency to a certain extent, they still have many shortcomings. The transmission method of the power source is often simple and crude. For example, they only rely on a small motor or engine to directly drive the fertilizer spreading parts, and lack an effective power combination and distribution mechanism. One of the prominent problems is that the working state of the fertilizer spreading mechanism lacks flexibility and cannot be effectively adapted to the driving speed of the fertilizer spreader. This means that the fertilizer spreader is running slowly at a low speed for fertilization operations, or running at a high speed for fertilization operations. When the driving speed changes, the speed of the fertilizer spreading mechanism cannot be automatically adjusted according to the change in driving speed, which may lead to uneven fertilization.

The power of the external single power source and the wheel driving is combined through the No. 2 transmission mechanism and transmitted to the conveying mechanism. Then, the single external power and the wheel driving power are combined to jointly control the transmission shaft for conveying fertilizer, so that the fertilizer spreader can make full use of the wheel driving rotation and the power of the external single power source, effectively integrate the power resources in the system, and make the power distribution more flexible.

[0022] 2. The speed regulating component can be used to further adjust the fertilizer delivery speed, so that when the wheel speed exceeds a certain rate, the delivery speed can be further accelerated, and there are multiple stages. This enables the fertilizer delivery speed to be automatically adjusted in multiple stages according to the driving state of the vehicle. When the vehicle is driving at high speed, fertilizer can be quickly delivered to improve work efficiency. In large-scale farmland fertilization operations, when the vehicle is driving quickly on field roads to transfer work areas, it can speed up fertilizer delivery and reduce the waste of non-working time. When driving at low speeds, fertilizer delivery can be slowed down to avoid excessive fertilization in the same area, resulting in crop seedling burns and other phenomena, affecting the growth of crops.
