Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a three-disc solid fertilizer spreader. Background Technology

[0002] In modern agricultural production, the application of solid fertilizers is a crucial step in improving soil fertility and ensuring crop growth. With the advancement of agricultural mechanization, solid fertilizer spreaders have gradually replaced traditional manual fertilization methods, significantly improving fertilization efficiency and uniformity. However, existing solid fertilizer spreaders still have some shortcomings in practical applications. For example, common single-disc or double-disc spreaders often face problems such as limited spreading range, insufficient distribution uniformity, and poor adaptability during operation. Especially in large-area farmland operations, these devices require multiple round trips to complete the fertilization task, which not only reduces operational efficiency but may also lead to uneven fertilizer distribution, affecting crop growth. Therefore, developing a spreading device that can achieve a wider range, higher uniformity, and adaptability to various fertilizer types has become an urgent technical challenge in current agricultural production. This utility model proposes a three-disc solid fertilizer spreader to overcome the above problems and provide a more efficient and precise fertilization solution for modern agriculture. Utility Model Content

[0003] The purpose of this utility model is to provide a three-disc solid fertilizer spreader that solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a three-disc solid fertilizer spreader, which includes: a frame, wheels set at the bottom of the frame, a hopper set on the frame, and a spreading mechanism set at the end of the frame. The frame is dragged by a trailer so that the hopper and the spreading mechanism below the hopper can spread fertilizer.

[0005] A further technical solution of this utility model is: a discharge port is provided below the hopper, and a valve is provided at the discharge port to control the discharge speed.

[0006] A further technical solution of this utility model is: the spreading mechanism is located directly below the discharge port, and the solid fertilizer falling from the discharge port falls onto the spreading mechanism.

[0007] A further technical solution of this utility model is: the spraying mechanism includes: a linkage, a drive shaft connected to the linkage, a first transmission shaft, a second transmission shaft and a third transmission shaft, the drive shaft is connected to the drive shaft of the vehicle, and the three transmission shafts are controlled to rotate by the linkage.

[0008] A further technical solution of this utility model is: the drive shaft is connected to the transmission mechanism of the vehicle frame, and the first transmission shaft, the second transmission shaft and the third transmission shaft are all provided with a spraying disc. The three spraying discs make the solid fertilizer spraying range wider and the fertilization more uniform.

[0009] A further technical solution of this utility model is: the spreading disc is provided with dispersing blades, which disperse the solid fertilizer before spreading it, thereby improving the uniformity of spreading.

[0010] The beneficial effects of this utility model are as follows: The three-disc solid fertilizer spreader of this utility model has a simple structure, long service life, and low failure rate. The three discs are driven by the vehicle drive shaft, which greatly improves the efficiency and spreads a wider range compared with manual spreading. Compared with double-disc machinery, it spreads more evenly and is more conducive to crop growth. Attached Figure Description

[0016] Example 1: Figures 1-3 A three-disc solid fertilizer spreader is shown. The spreader includes: a frame 1, wheels 2 mounted at the bottom of the frame 1, a hopper 3 mounted on the frame 1, and a spreading mechanism 4 located at the end of the frame 1. The frame is towed by a trailer, causing the hopper and the spreading mechanism below it to spread fertilizer. A discharge port 31 is located below the hopper 3, and a valve controls the discharge speed. The spreading mechanism 4 is located directly below the discharge port 31, and solid fertilizer falling from the discharge port lands on the spreading mechanism. The spreading mechanism 4 includes: a linkage 42, a drive shaft 41 connected to the linkage 42, a first transmission shaft 43, a second transmission shaft 44, and a third transmission shaft 45. The drive shaft is connected to the vehicle's drive shaft, and the rotation of the three transmission shafts is controlled by a linkage. The drive shaft 41 is connected to the transmission mechanism of the frame 1. Spreading discs 7 are provided on the first transmission shaft 43, the second transmission shaft 44, and the third transmission shaft 45. The three spreading discs allow for a wider spreading range and more even fertilization of the solid fertilizer. The spreading discs 7 are equipped with dispersing blades 71, which disperse the solid fertilizer before spreading, improving the evenness of the spreading. This three-disc solid fertilizer spreader has a simple structure, long service life, and low failure rate. Driven by the vehicle's drive shaft, the three discs significantly improve efficiency and spread a wider range compared to manual spreading. Compared to dual-disc machines, it spreads more evenly, which is more beneficial to crop growth.
