Description

Technical Field

[0001] The utility model relates to fertilizer application equipment, in particular to a fertilizer conveying device applied to the fertilizer application equipment. Background Art

[0002] Soil fertilization refers to the agricultural practice of applying fertilizer to the soil to provide nutrients needed by plants (such as tobacco, wheat, corn, and sweet potatoes) and to maintain and improve soil fertility. The primary goals of soil fertilization are to increase crop yields, improve crop quality, enhance soil fertility, and increase economic returns. Therefore, rational and scientific fertilization is one of the key means of maintaining sustainable agricultural development.

[0003] Traditional soil fertilization methods generally rely on manual fertilization, which results in less than ideal fertilization uniformity and requires significant physical effort. To address these issues of fertilization uniformity and farmer labor intensity, the inventor previously applied for a Chinese patent titled "A Fertilizer Apparatus and Soil Covering Machine with More Uniform Fertilization," with patent number ZL202320345449.6 and a grant announcement date of October 22, 2024. The patent discloses "a fertilization apparatus comprising a storage device for temporarily storing fertilizer, a feeding device located below the storage device and configured to quantitatively fertilize the soil, and a quantitative fertilization device for discharging the fertilizer from the storage device into the feeding device in a quantitative manner." This fertilization apparatus achieves more uniform fertilization. The fertilizer (such as granular or powdered fertilizer) in the storage device is fed into the feeding device through a rotating distributor within the feeding device, discharging the fertilizer from multiple quantitative troughs on its outer circumference into the feeding device for quantitative fertilization, resulting in more uniform fertilization. Although the above-mentioned quantitative fertilization device can achieve uniform fertilization and solve the problem of uniform fertilization of a single fertilizer, its structure is complex, and the fertilizer transportation efficiency is not high and smooth, thereby affecting the fertilization effect of the mixed fertilizer. Utility Model Content

[0007] Furthermore, the fertilizer conveying device also includes a mounting frame for supporting the conveyor belt and mounted on a walk-behind frame. The conveyor belt includes a horizontally arranged driving shaft, a driven shaft, and a conveyor belt wound between the driving and driven shafts.

[0008] Furthermore, a limit adjustment member is provided on the right side of each U-shaped enclosure for blocking and adjusting the fertilizer on the conveyor belt and located inside the U-shaped enclosure. Each limit adjustment member includes an N-shaped rod fixed to the U-shaped enclosure and provided with an adjusting bolt, and a baffle plate arranged to block the fertilizer and adjustable up and down. A strip opening is provided on the baffle plate, and the baffle plate is provided with an adjusting bolt passing through the strip opening and locking it to achieve limited transportation of the fertilizer inside the U-shaped enclosure.

[0009] Furthermore, the driven shaft includes a fixed spindle and a rotating sleeve that is sleeved on the fixed spindle and can rotate; the mounting frame is provided with two adjustment blocks arranged front and back, and the two adjustment blocks are respectively located at the two ends of the fixed spindle, and each adjustment block is provided with a horizontal strip opening through which the end of the fixed spindle passes and can be adjusted left and right, and each adjustment block is also provided with an adjusting nut, and an adjusting screw is screwed on each adjusting nut, and the driven shaft adjusts the tightness of the conveyor belt by the top of the two adjusting screws contacting the end of the corresponding fixed spindle.

[0010] Furthermore, the conveyor belt includes a first conveyor belt and a second conveyor belt that are spaced apart from each other, and the first and second conveyor belts are respectively located directly below the first and second feeding openings.

[0011] From the above description of the utility model, it can be seen that compared with the existing technology, the advantages of the utility model are: the structural design of the fertilizer conveying device is ideal, and the design of the conveyor belt combined with the first and second guide members is adopted, and the overall structure is simple. After the mixed fertilizer (i.e., granular fertilizer and powder fertilizer) in the fertilizer unloading device falls into the conveyor belt, it will be promptly conveyed to the side of the fertilizer discharge device by the conveyor belt, and the conveying is more timely and smoother, the fertilizer conveying efficiency is high, and the fertilization effect of the mixed fertilizer is improved. The design of the limited adjustment member can limit the delivery of fertilizer in the baffle, so that the amount of fertilizer applied can be adjusted for different acres of land. Precisely control the amount of fertilizer applied. Refined fertilization operation. The design of two adjustment blocks makes it easy to adjust the tightness of the conveyor belt, avoiding the problem of the conveyor belt becoming loose due to the vibration and bumping of the mounting frame when the covering machine is moving.
