Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production equipment, in particular to a fertilizer bagging device which is convenient for fixing a bag opening. Background Art

[0002] Fertilizer, short for chemical fertilizer, is a fertilizer made by chemical and / or physical methods that contains one or more nutrients required for the growth of crops. These nutrients mainly include nitrogen, phosphorus, potassium, etc., which play a vital role in the growth and development of plants. There are many types of fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. Fertilizer production mainly involves process flows such as raw material processing, mixing, granulation, drying, and screening, and finally produces granular fertilizers of specific shapes and sizes. Granular fertilizers need to be bagged and packaged before leaving the factory.

[0003] When some existing fertilizer bagging devices are in use, the bag opening fixing devices thereon are fixed in size and cannot be adjusted according to the size of the packaging bag, resulting in the inability to firmly fix packaging bags of different sizes, thereby affecting the packaging effect and sealing quality.

[0004] For example, a packaging device for fertilizer production disclosed in announcement number CN214058084U has a telescopic sealing cover welded to the bottom of an electronic discharge valve to seal the gap between the electronic discharge valve and the device support frame, thereby avoiding the splashing of fertilizer during the fertilizer production and packaging process. A packaging bag opening groove is provided on the surface of the telescopic sealing cover to facilitate the fixing and placement of the bag opening of the fertilizer packaging bag. After the fertilizer is filled, the bag opening of the fertilizer packaging bag is pulled out through the thermal sealer embedded in the bottom of the telescopic sealing cover, and the fertilizer packaging bag is heat-sealed using the thermal sealer to complete the packaging and sealing operation of the fertilizer.

[0005] Although the above-mentioned packaging device for fertilizer production has functions such as electric lifting, electronic discharge valve, and thermal sealing, it lacks adaptability to packaging bags of different sizes. The size of the telescopic sealing cover and the packaging bag mouth groove is fixed and cannot be adjusted according to the size of the packaging bag, resulting in the inability to firmly fix packaging bags of different sizes, thereby affecting the packaging effect and sealing quality. In addition, the lack of a size adjustment mechanism also limits the flexibility and versatility of the device, making it difficult to meet the packaging needs of packaging bags of various sizes.

[0006] Therefore, it is necessary to invent a fertilizer bagging device that is convenient for fixing the bag opening to solve the above problems. Utility Model Content

[0012] Preferably, the outer surface of the frame-shaped loading plate close to the supporting column is fixedly connected with a limiting slider, and the limiting slider is slidably connected with the limiting sliding groove.

[0013] The sliding connection mode of the limit sliding block and the limit sliding groove makes the frame-shaped loading plate more stable during the lifting process.

[0014] Preferably, a feeding hopper is fixedly connected to the middle of the top plate, and a corrugated telescopic tube is fixedly connected to the bottom output end of the feeding hopper.

[0015] The design of the feeding hopper allows the fertilizer to flow in in a centralized manner, while the bellows can adapt to different filling heights, enhancing the flexibility of the device.

[0016] Preferably, a discharge pipe opening is fixedly connected to the bottom output end of the corrugated telescopic tube, and an electronic discharge valve is installed in the middle of the discharge pipe opening.

[0025] 1. The No. 1 electric push rod controls the lifting and lowering of the frame-shaped loading plate, and the No. 2 electric push rod adjusts the position of the support hook, so that the device can adaptively adjust the opening degree of the bag opening according to fertilizer packaging bags of different sizes. This design enables the device to easily handle packaging bags of various specifications without frequent replacement or adjustment of equipment components, greatly improving the convenience and versatility of bagging;

[0026] 2. The four support hooks can pull the bag opening open from four directions respectively, thus forming a stable support structure to ensure that the bag opening of the fertilizer packaging bag remains open during the filling process, preventing the fertilizer from leaking due to the closure of the bag opening. This design not only improves the efficiency of bagging, but also ensures the quality of bagging, making the filling of fertilizer more accurate and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
