Technical Field

[0001] The utility model belongs to the technical field of fertilizer preparation equipment, in particular to a fertilizer production stirring and mixing equipment. Background Art

[0002] Fertilizer is the material basis of agricultural production. There are many types of fertilizers, and each fertilizer has its specific role and effect. Correctly selecting and using different types of fertilizers is crucial to improving agricultural production efficiency and crop quality. Therefore, in the process of fertilizer production, stirring and mixing equipment is usually used to mix and proportion fertilizer raw materials according to usage requirements. The technical solution provided by the utility model patent with announcement number CN212417656U and the name "A stirring and mixing device for the production of microbial fertilizers" is that when stirring and mixing fertilizer raw materials, the tank cover is opened, the fertilizer is added into the box, and the combination of multiple groups of stirring blades driven by the brake motor is used to stir and mix the fertilizer raw materials. This method of directly feeding the fertilizer raw materials and then stirring and mixing them with the stirring parts is very easy to appear damp and agglomerate, and the particles are of different sizes. The direct feeding and stirring and mixing often cannot make the various raw materials fully combined and mixed, and the mixing quality cannot be guaranteed. Utility Model Content

[0005] Its additional technical features are: the weighing hopper device is two groups symmetrically arranged;

[0006] The weighing sensors are four symmetrically arranged at the corners of the bottom surface of the weighing platform;

[0007] The grinding roller is an ellipsoidal structure, and the roller surface of the grinding roller is provided with grinding threads;

[0008] The multiple groups of stirring paddles are arranged at equal intervals on the second brake shaft;

[0009] The centrifugal paddle is spiral.

[0010] The first process of the fertilizer production stirring and mixing equipment provided by the utility model is to quantitatively discharge and crush the fertilizer raw materials. The fertilizer raw materials to be mixed are added into the hopper, and then the rotating motor is controlled to work. The rotating motor drives the combination of the grinding roller and the rotary push paddle to operate in linkage. The rotation of the rotary push paddle is used to drive the dynamic discharge of the fertilizer raw materials in the hopper. The rotation of the grinding roller is used to gradually roll-grind the fertilizer raw materials that fall into the crushing tube, so that the fertilizer raw materials are quantitatively discharged and crushed. The fertilizer raw materials are fed into the mixing tank through the discharge pipe that is connected to the mixing tank for the stirring and mixing process. While feeding the fertilizer raw materials, the weighing combination of the weighing sensor and the weighing platform is used to dynamically weigh the fertilizer raw materials in the hopper, and the fertilizer raw materials in the hopper are fed into the mixing tank according to the specified ratio weight for stirring and mixing. The fertilizer raw materials are added in a uniformly crushed state for the stirring and mixing process, so as to avoid the problem of poor mixing quality caused by the fertilizer raw materials being agglomerated and having different particle sizes. By utilizing the weighing combination of the weighing platform and the weighing sensor in the weighing hopper device, the fertilizer loading weight can be dynamically weighed to ensure the accuracy of the fertilizer loading ratio and improve the quality and efficiency of the mixing. The weighing hopper device is a symmetrical arrangement of two groups, and the weighing sensors are four symmetrically arranged at the bottom corners of the weighing platform, which work more accurately. The grinding roller is an ellipsoidal structure, and the roller surface of the grinding roller is provided with grinding wire teeth. By utilizing the ellipsoidal grinding roller, the fertilizer raw materials falling into the crushing tube are gradually roller-milled and crushed, so that the fertilizer raw materials are loaded into the mixing tank in a quantitative unloading and crushed state, so as to avoid the problem of poor mixing quality caused by the fertilizer raw materials being agglomerated and having different particle sizes.

[0011] The second process of the fertilizer production stirring and mixing equipment provided by the utility model is stirring and mixing. After the fertilizer raw materials are loaded and proportioned to the mixing tank, the brake motor is controlled to work, and the brake motor drives the first brake shaft to rotate, and the rotation of the first brake shaft drives the first brake gear to rotate, and the transmission combination of the first brake gear, the transmission gear, and the second brake gear drives the second brake shaft to rotate synchronously with the first brake shaft. While the first brake shaft rotates, it drives the spiral centrifugal paddle to rotate, and pushes the fertilizer raw materials at the bottom of the mixing tank upward, promoting the dynamic flow of the fertilizer raw materials, so as to facilitate more comprehensive stirring and mixing, and at the same time facilitate the subsequent unloading work, avoiding the blockage of the unloading pipeline. While the second brake shaft rotates, it drives the stirring paddle to rotate, and stirs and mixes the fertilizer raw materials flowing in the mixing tank again, so that the fertilizer raw materials are fully stirred and mixed, and the mixing ratio is more efficient and comprehensive, and the mixing quality is more accurate. Multiple groups of stirring paddles are arranged at equal intervals on the second brake shaft, and the centrifugal paddle is spiral, and the stirring and mixing effect is good.
