Description

Technical Field

[0001] The utility model relates to the field of fertilizer application equipment machinery, in particular to a fertilizer feeding device applied to 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. The above-mentioned fertilizing equipment can solve the problem of uniform fertilization of a single fertilizer, but there are still some shortcomings. The feeding hopper of the feeding device is designed with a single cavity structure, which cannot realize the independent feeding operation of the mixed material (such as granular fertilizer and powder fertilizer). Moreover, the feeding port is easily blocked, resulting in poor feeding, thereby affecting the fertilization effect of the mixed fertilizer. Utility Model Content

[0004] The utility model provides a fertilizer feeding device for fertilizer application equipment, which aims to overcome the shortcomings of the existing feeding hopper being designed with a single cavity structure, which cannot realize the independent feeding operation of mixed materials (such as those composed of granular fertilizers and powdered fertilizers), and the feeding port is easily blocked, resulting in poor feeding.

[0005] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0006] A fertilizer discharging device used in fertilizer spreading equipment includes a discharging hopper with a discharging baffle and a spiral shaft horizontally placed in the discharging hopper and rotatable. The discharging baffle divides the discharging hopper into a first cavity for storing granular fertilizer and a second cavity for storing powdered fertilizer. A first discharging port for discharging granular fertilizer in the first cavity and a second discharging port for discharging powdered fertilizer in the second cavity are provided at the bottom of the discharging hopper. The spiral shaft is located directly above the first and second discharging ports.

[0007] Furthermore, the lower hopper is also provided with left and right stirring members which are arranged horizontally at intervals and located above the spiral shaft. The left and right stirring members each include a stirring shaft and a number of stirring blades arranged in sequence along the length direction of the stirring shaft. The front and rear ends of each stirring shaft are rotatably connected to the side wall of the lower hopper through two bearings, and the front end extends outward to be exposed outside the side wall of the lower hopper, and the exposed front end is equipped with a stirring gear; the front and rear ends of the spiral shaft are also rotatably connected to the side wall of the lower hopper through two bearings, and the front end extends outward to be exposed outside the side wall of the lower hopper, and the exposed front end is equipped with a spiral gear; the two stirring gears and one spiral gear form a triangular structure, and a chain is wound around it, which drives the two stirring shafts to rotate synchronously through the rotation of the spiral shaft.

[0008] Furthermore, the front end of the spiral shaft is also provided with a first rotating wheel, the front end of the driving shaft of the conveyor belt is provided with a second rotating wheel and a third rotating wheel, a first transmission belt is arranged between the first rotating wheel and the second rotating wheel, and a second transmission belt is arranged between the third rotating wheel and the driving wheel of the fertilizer transmission mechanism.

[0009] From the above description of the utility model, it can be seen that compared with the prior art, the advantages of the utility model are: the structural design of the fertilizer discharging device is ideal, and the design of a discharging hopper with a discharging baffle combined with a spiral shaft can realize the independent discharging operation of the mixed material (such as granular fertilizer and powder fertilizer), and through the rotatable operation of the spiral shaft, the discharging of the discharging port (i.e., the first and second discharging ports) is smoother and less prone to clogging, thereby improving the fertilizing effect of the mixed fertilizer.
