Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to automatic unloading filling equipment for fertilizer production. Background Art

[0002] Fertilizer, the full name of which is chemical fertilizer, refers to fertilizer made by chemical and / or physical methods that contains one or more nutrients required for the growth of crops. It mainly includes nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, micro-fertilizer, compound fertilizer, etc. It is an important material basis in agricultural production and plays an important role in improving the yield and quality of crops. In the fertilizer production process, the formed fertilizer particles need to be filled into packaging bags. Traditional fertilizer filling and bagging methods often use manual or semi-automatic mechanical operations, which is not only inefficient, but also difficult to ensure the accuracy and consistency of bagging. In addition, manual operation is easily affected by factors such as worker proficiency and fatigue, resulting in unstable product quality.

[0003] When some existing fertilizer filling equipment is in use, it is provided with a spiral auger for pushing and unloading materials, but the spiral auger is placed vertically. When the fertilizer is unloaded, the fertilizer particles at the end blades of the spiral auger are not blocked or supported and will fall quickly under the action of gravity. The unloading operation lacks buffer time and cannot achieve more accurate weighing adjustment.

[0004] For example, a fertilizer production filling equipment disclosed in announcement number CN212149345U drives the filling tube downward by controlling the regulator, so that the output end of the filling tube is inserted into the packaging bag, thereby preventing the fertilizer particles from falling to the outside of the packaging bag when being input through the filling tube. At the same time, the servo motor is controlled to drive the driving wheel on the motor shaft to rotate during feeding, and the driven wheel is driven to rotate at the same time through the belt, so that two sets of stirring rods stir the fertilizer in the filler respectively to ensure its uniformity, and drive the auger to rotate during the stirring process to feed the material, thereby preventing the filling tube from being blocked during discharging, and controlling the discharging speed by controlling the servo motor speed to ensure the discharging effect.

[0005] However, the auger of this patent is placed vertically. When feeding fertilizer, the fertilizer particles at the spiral blades at the end of the auger will fall down quickly under the action of gravity. The feeding operation lacks buffer time and cannot achieve more accurate weighing adjustment.

[0006] Therefore, it is necessary to invent a kind of automatic unloading fertilizer production filling equipment to solve the above problems. Utility Model Content

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual Figure 1-5When using the utility model, first open the sealing cover 11, inject a certain amount of fertilizer particles into the storage box 1, and then close the sealing cover 11 to prevent the fertilizer particles from being exposed to the air and getting damp.
