Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices for nitrogen fertilizer production, specifically a mixing device with a structure that prevents dead angle mixing. Background Technology

[0002] Chinese patent document CN220446862U discloses a mixing device for production. This device includes a mixing drum, with a motor fixedly connected to the top of the drum. The bottom of the motor extends into the drum, and a rotating rod is fixedly connected to the bottom of the motor. A stirring mechanism is provided on the surface of the rotating rod, comprising a first stirring rod fixedly connected to the rotating rod and rotatably connected within the mixing drum. A rotating shaft is rotatably connected to the side of the first stirring rod away from the rotating rod, and a push plate is fixedly connected to the other side of the rotating shaft. The rotation of the first stirring rod causes a scraper and a second stirring rod to rotate in two different directions within the mixing drum, allowing the material in the mixing drum to easily impact itself after being subjected to forces from these different rotational directions.

[0003] When the above-mentioned solutions and existing technologies are used to mix nitrogen fertilizer raw materials in the mixing device, some of the raw materials are stirred to the top dead corner of the nitrogen fertilizer mixing cylinder during the mixing process. The raw materials in the top dead corner are difficult for the mixing device to clean, resulting in insufficient mixing effect. The existing solution is generally for workers to use tools to scrape off the raw materials in the top dead corner and then mix the raw materials again. This operation is cumbersome and cannot meet the actual use requirements.

[0004] Therefore, this utility model proposes a mixing device with a dead-angle-prevention mixing structure to solve the above problems. Utility Model Content
