Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a crushing device. Background Art

[0002] Flue-cured tobacco, also known as fire-cured tobacco, originates from Virginia in the United States and is therefore also known as the Virginia type. It has unique morphological characteristics (petioles are indistinct or winged, terminal panicles, calyx is tubular or tubular-bell-shaped, corolla is funnel-shaped with a pink tip, and capsules contain round or broadly oblong, yellowish-brown seeds). Flue-cured tobacco is the most cultivated tobacco type in my country and the world. It is the primary raw material for the cigarette industry and is also used as pipe tobacco.

[0003] Flue-cured tobacco cultivation, as a popular industry that saves time and effort and has a quick and reliable "short, flat and fast" economic benefit recovery, is suitable for cultivation and development in many rural areas of the vast my country, especially in the ethnic mountainous areas in Yunnan Province, which is located inland and has extremely scarce sea, land and air transportation conditions in the southwest of the motherland. Practice has shown that "it has become a sustainable development industry that many tobacco farmers are happy to accept." It has played an obvious function and role in consolidating and revitalizing the "three rural" economy of the vast border and poor ethnic minority areas and optimizing their social and economic forms. When making the growth matrix of flue-cured tobacco, a crusher needs to be used.

[0004] The Chinese utility model patent (authorization announcement number: CN210610545U, name: A device for making nutrient soil for flue-cured tobacco) includes a lower hopper and a crushing chamber that receives the lower hopper's discharge port. The motor and its gearbox drive the rotating shaft to rotate. The rotating shaft passes through the crushing chamber. The two ends of the rotating shaft in the crushing chamber are respectively fixed to the centers of two turntable cutters. Several auxiliary rotating shafts parallel to the rotating shaft are fixed between the two turntable cutters. The auxiliary rotating shafts pass through the through holes on several rectangular blades. The rectangular blades are axially positioned and evenly suspended on the auxiliary rotating shafts. The rectangular blades can rotate around the auxiliary rotating shafts. The bottom surface of the crushing chamber is a fence structure. The rotating shaft drives the turntable knife and the rectangular blade to rotate, cutting and crushing the nutrient soil in the crushing chamber. At the same time, the rectangular blade can rotate around the auxiliary rotating shaft, so the rotating shaft or the auxiliary rotating shaft will not be stuck. It is suitable for the crushing and mixing processing of flue-cured tobacco nutrient soil with undried yellow mud as the main material, which significantly improves the working efficiency, reduces energy consumption and reduces costs. However, during the crushing process, the high-speed rotation will increase the temperature in the crushing chamber, and the continuous high temperature will easily cause the destruction of nutrients.
