Description

Technical Field

[0001] This application relates to the technical field of agricultural fertilizer mixing, and in particular to an agricultural fertilizer mixing device. Background Technology

[0002] In modern agricultural production, the uniform mixing of fertilizers is a crucial step in improving fertilization effectiveness. Whether it's a compound ratio of organic and chemical fertilizers or a mixture of fertilizers with different nutrients, a mixing device is needed to achieve particle dispersion and uniform distribution of components, ensuring balanced nutrient absorption by crops. For example, in fruit and vegetable cultivation, uneven fertilizer mixing can lead to localized excessive soil nutrients, causing root burn; while in field crop cultivation, uneven fertilizer application can result in uneven crop growth and yield reductions of up to 10%-15%.

[0003] With the development of large-scale and intensive agriculture, the types of fertilizers are becoming increasingly diverse (such as powdered, granular, and paste-like organic fertilizers, slow-release compound fertilizers, etc.), which places higher demands on the adaptability, efficiency, and mixing precision of mixing devices. Mixing devices not only need to crush clumps of fertilizer but also need to achieve uniform blending of fertilizers in different physical states to provide high-quality raw materials for subsequent fertilization processes (such as broadcasting and drip irrigation).

[0004] With the advancement of the concept of green agricultural development, the combined application of organic and chemical fertilizers has become mainstream. Fertilizer compositions are becoming more complex, placing higher demands on mixing equipment. Existing equipment, in terms of caking and crushing, uniform mixing, and coordinated feeding, is no longer able to meet the demands of modern agriculture for "high efficiency, precision, and energy saving."

[0032] The material distribution mechanism includes a feeding hopper 17 and a material distribution cylinder 27. The feeding hopper 17 is fixedly connected to the inner side wall of the box 1 and is located below the two crushing rollers 16. The lower surface of the feeding hopper 17 is fixedly connected to a feeding box 19. The material distribution cylinder 27 is rotatably installed inside the feeding box 19 via a mounting shaft 20. Multiple material distribution slots 28 are evenly opened on the side wall of the material distribution cylinder 27. The box 1 is provided with a drive mechanism for driving the material distribution cylinder 27 to rotate.

[0033] The drive mechanism includes a drive motor 7, a full gear 13, and a half gear 12. The drive motor 7 is fixedly connected to one side of the housing 1. One end of the mounting shaft 20 is movably connected through the side wall of the feeding box 19 and rotatably connected to the inner side wall of the housing 1. The other end of the mounting shaft 20 is movably connected through the feeding box 19 and the side wall of the housing 1 and extends to the outside and is fixedly connected to the full gear 13. A fixed shaft 29 parallel to the mounting shaft 20 is rotatably mounted on the inner side wall of the housing 1.

[0034] The stirring mechanism includes two stirring rollers 21, both of which are rotatably connected to the inner side wall of the housing 1. Multiple stirring blades 22 are fixedly connected to the side wall of each of the two stirring rollers 21. An electric motor 8 for driving one of the stirring rollers 21 to rotate is fixedly installed on one side of the housing 1. The two stirring rollers 21 are connected to each other through a transmission assembly, which includes two synchronous pulleys 14. One end of each of the two stirring rollers 21 is movably passed through the side wall of the housing 1 and then fixedly connected to a synchronous pulley 14.

[0035] A guide plate 24 is fixedly connected to the bottom side inside the box 1. The upper surface of the guide plate 24 is inclined and is used in conjunction with the discharge port 23.

[0036] A controller 2 and an observation window 10 are respectively installed on one side of the housing 1. The servo motor 4, drive motor 7 and motor 8 are all electrically connected to the controller 2 to realize intelligent control of the equipment.

[0037] The implementation principle of the agricultural fertilizer mixing device in this application embodiment is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. During operation, the fertilizer to be processed is fed into the feed inlet 3 at the top of the housing 1, first entering the crushing mechanism. The controller 2 starts the servo motor 4, which drives the connecting shaft 5 to rotate. The two active bevel gears 25 on the connecting shaft 5 rotate synchronously, and the driven bevel gear 26 meshing with the active bevel gear 25 drives the two roller shafts 11 to rotate in opposite directions, causing the crushing rollers 16 fixed on the roller shafts 11 to rotate relative to each other, thus squeezing, shearing, and crushing the fed agglomerated fertilizer. The crushed fertilizer falls into the lower feed hopper 17. The crushed fertilizer enters the feed box 19 through the feed hopper 17. The controller 2 starts the drive motor 7, which drives the fixed shaft 29 to rotate, and the half gear 12 on the fixed shaft 29 rotates accordingly. When the half gear 12 meshes with the full gear 13, it drives the mounting shaft 20 and the distribution cylinder 27 to rotate. The distribution groove 28 on the side wall of the distribution cylinder 27 receives the fertilizer. When the half gear 12 disengages from the full gear 13, the distribution cylinder 27 stops rotating, and the fertilizer in the distribution groove 28 falls naturally into the mixing mechanism, achieving intermittent and uniform distribution of fertilizer and avoiding insufficient mixing due to excessive material feeding at one time. After the fertilizer enters the mixing area, the controller 2 starts the motor 8, which drives one of the mixing rollers 21 to rotate. Through the transmission action of the two synchronous pulleys 14 and the synchronous belt 15, the two mixing rollers 21 rotate synchronously, and the mixing blades 22 thoroughly mix the fertilizer. After mixing is completed, the sealing door 9 is opened, and the uniformly mixed fertilizer is discharged from the outlet 23 under the guidance of the inclined guide plate 24. The entire process can be observed through the observation window 10 to monitor the internal working status. The controller 2 realizes the coordinated control of each mechanism to ensure orderly operation.

[0038] During this process, the crushing mechanism employs two relatively rotating crushing rollers 16, coupled with a bevel gear transmission assembly, to efficiently break up clumps of fertilizer, laying the foundation for subsequent uniform mixing. The dispensing mechanism, through the intermittent meshing of half gear 12 and full gear 13, drives the dispensing cylinder 27 to rotate periodically, ensuring that the fertilizer falls evenly according to the set amount, avoiding excessive mixing load or uneven mixing caused by excessive feeding at one time. The mixing mechanism adopts a double-roller rotating design 21, with the mixing blades 22 working together to form convective mixing, significantly improving the uniformity of fertilizer mixing, ensuring balanced soil nutrients after fertilization, and enhancing the practicality of the device.
