Description

Technical Field

[0001] The utility model relates to the technical field of filling machines, in particular to a multi-station automatic liquid fertilizer filling machine. Background Technique

[0002] Liquid fertilizer is a new type of fertilizer. As an essential production material in the agricultural production process, it plays a decisive role in ensuring the increase of crop yields and incomes. According to different technical formulas and production processes, the major elements and medium and trace elements required by plants are combined into a liquid form. It not only has a high nutrient content and is easy to compound, but also can be directly absorbed by crops; applying liquid fertilizers can also activate the nutrients in the soil, reduce the negative impacts brought by excessive application of chemical fertilizers, and has a good effect on improving soil structure, activating soil nutrients, and coordinating water and fertilizers.

[0003] An automatic liquid fertilizer filling machine is a kind of machine used for filling liquid fertilizers. It is a small category of products in packaging machines. In order to assist the automatic filling machine to operate at multiple stations, a multi-station automatic liquid fertilizer filling machine is needed.

[0004] In the process of using traditional automatic liquid fertilizer filling machines, the transmission mechanism is used to drive the storage cylinder to move to the bottom of the filling machine, and then the filling machine is used to fill the inside of the storage cylinder. However, in the process of using traditional automatic liquid fertilizer filling machines, the filling efficiency of filling one by one is relatively low, which affects the use efficiency of the device. Moreover, it is difficult for traditional filling machines to follow the sizes of different storage cylinders for limit adjustment and ensure that different-sized storage cylinders are stably clamped and limited, thus affecting the stable use of the device.
