Description

Technical Field

[0001] The utility model relates to the technical field of mixers for fertilizer production equipment, in particular to a multifunctional crushing and stirring mechanism for fertilizers. Background Art

[0002] China ranks first in the world in fertilizer production and usage. Excessive fertilizers lead to a decrease in soil organic matter content and fertility; weakened disease resistance, cold resistance, drought resistance, and lodging resistance of crops, resulting in a decrease in crop quality and yield; damage to agricultural water sources and the environment; and a large amount of scarce resources are wasted, such as coal, high-grade phosphate rock, and sulfur resources. Therefore, the development of new environmentally friendly fertilizers, high-efficiency compound fertilizers, how to effectively and reasonably apply fertilizers, and how to improve fertilizer utilization have become important issues.

[0003] Fertilizer production equipment mainly consists of a turner, a crusher, a batching machine, a mixer, a granulator, a dryer, a cooler, a drum screening machine, a film coating machine, and an automatic packaging machine. A crusher is a machine that crushes large-sized solid raw materials into required sizes. A mixer is a machine that has a shaft with blades rotating in a cylinder or a trough to mix and blend a variety of raw materials into a mixture. Both are basic equipment on the organic fertilizer production line and are generally divided into two processes and two equipment. In order to optimize the process and save costs, the crushing and mixing processes can be combined into one process and completed in one device. For example, the Chinese invention with the announcement number CN 217410606 U discloses a compound fertilizer feeding and mixing vertical mixer, including a first material tank and a second material tank, the first material tank is detachably plugged into the interior of the second material tank, a stirring device is arranged inside the first material tank, the stirring device includes a support part and a crushing part arranged on the surface of the support part, a speed regulating motor for driving the stirring device to rotate is arranged at the bottom of the first material tank, a discharge hole is opened at the bottom of the outer wall of the first material tank, and a fertilizer storage area is arranged between the outer side of the first material tank and the inner side of the second material tank. While stirring the fertilizer, the agglomerated fertilizer can also be crushed, so that the agglomerated fertilizer is broken, and the broken fertilizer will enter the fertilizer storage area through the discharge hole under the action of centrifugal force, thereby achieving the purpose of crushing the agglomerated fertilizer, solving the problem that the traditional agglomerated fertilizer cannot be fully stirred. However, the invention is provided with a first material tank and a second material tank, the structure is relatively complex, and the stirring device is mainly used for stirring. How to make the two functions of crushing and stirring be realized simultaneously in the same device is worth studying and designing. Summary of the invention
