Description

Technical Field

[0001] The invention relates to the technical field of fertilizer preparation, in particular to an energy-saving and environment-friendly agricultural fertilizer preparation device. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties and increases soil fertility levels. It is one of the material bases of agricultural production. When producing compost, existing chemical fertilizers need to be placed in sealed tanks for fermentation and stirred regularly during fermentation. Large-scale composting production usually involves digging compost pits and installing corresponding processing equipment, and most of the equipment is electrically driven, which consumes more electricity during the composting production process. In addition, the equipment installed in the compost pits will also be corroded and damaged by the acid and alkali substances produced during composting. Patent documents have now been published to improve this.

[0003] For example, Chinese patent CN221588383U, an energy-saving and environment-friendly agricultural fertilizer preparation device, relates to the technical field of agricultural fertilizer preparation equipment, a support shaft is fixedly arranged on the compost tank, the compost tank is rotated on the frame through the support shaft, there are two sprockets, which are respectively rotated on the upper and lower ends of the frame through bearings, and the lower sprocket is connected to the support shaft in a transmission manner, the chain is meshed and wound around the sprocket, the energy storage counterweight is fixed on the chain, and the energy storage counterweight is slidably mounted on the frame, the drive shaft is rotated on the upper end of the frame through a bearing, the upper sprocket is connected to the drive shaft in a transmission manner, and the wind energy fan blades are fixed on the drive shaft; it adopts wind energy storage to drive the stirring of the device, and the energy storage structure mostly adopts a mechanical structure, rather than using chemical batteries to drive the main body, so that the device can effectively utilize natural energy and realize energy-saving and environmentally friendly production of the device.

[0004] Although the equipment in the above document can use wind power to store energy and stir fertilizer, it still has obvious defects in actual use, such as: The raw materials for fertilizer stacking are mostly waste materials, and these fertilizers are usually solid. Therefore, these solids have a large density after being loaded into the tank. However, the equipment in the document only uses the weight to drop and the chain to drive the stirring rod to stir the fertilizer, which is impossible. At the same time, the transmission parts such as the chain will also reduce the kinetic energy, resulting in the stirring rod not having enough force to drive in the solid waste, which reduces the overall practicality of the equipment; Therefore, an energy-saving and environment-friendly agricultural fertilizer preparation device capable of improving preparation efficiency and quality is now designed to solve such defects.

[0014] The present invention provides an energy-saving and environment-friendly agricultural fertilizer preparation device. Compared with the existing technology, it has the following beneficial effects: (1) The energy-saving and environment-friendly agricultural fertilizer preparation device combines a fermentation sampling mechanism and a stirring expansion mechanism. The arrangement of these two mechanisms enables a motor to drive a plurality of vertical rotating plates and stirring blades to fully stir the fertilizer when the fertilizer is placed in a sealed fermentation tank for fermentation. The photovoltaic panels on the top of the load-bearing platform can perform photovoltaic power storage to provide auxiliary power for the motor, thereby achieving the purpose of energy saving and environmental protection.

In addition, the polygonal rotating rod is used for transmission. When the polygonal rotating rod rotates, it also drives the annular disk and the arc-shaped convex seat to rotate synchronously. When the arc-shaped convex seat rotates, it continuously squeezes the lifting rod to lift the sampling frame to the inside of the sealed fermentation tank and bring the fertilizer into the sample storage tube, so that the staff can observe the fermentation situation from the outside without opening the sealing cover, thereby avoiding damage to the fermentation environment.

After the plurality of vertical rotating plates are flipped, they are in an expanded state, which effectively facilitates the staff to clean the vertical rotating plates and the mixing blades, and satisfies the current use.

The surface of the rotating rod 206 is fixedly connected with a dome plate 213 located on the upper part of the cylindrical guide cylinder 105. The surface of the rotating rod 206 is fixedly connected with an auger blade 207 used in conjunction with the cylindrical guide cylinder 105. Since the fertilizer is a solid object, the auger blade 207 can drive it to lift upward. The surface of the dome plate 213 is fixedly connected with an inner horizontal plate 208, and the inner horizontal plate 208 is provided with a plurality of them. One side of the bottom of the inner horizontal plate 208 is rotatably connected with a vertical rotating plate 209 through a rotating member. The bottom end of the rotating plate 209 is fixedly connected with an arc-shaped correction block 210 used in conjunction with the limiting guide groove 106, and one side of the vertical rotating plate 209 is fixedly connected with a stirring blade 212. The bottom of the inner horizontal plate 208 is rotatably connected with a curved abutment plate 211 used in conjunction with the vertical rotating plate 209 through a bearing member. The top of the sealing cover 203 is provided with a circular slot 214 used in conjunction with the curved abutment plate 211 and the inner horizontal plate 208.
