Transmission device of chain plate circulation type tea leaf withering drying machine and work method thereof

Abstract

The invention relates to a transmission device of a chain plate circulation type tea leaf withering drying machine and a work method thereof. The transmission device is characterized by comprising a hot air furnace and a withering drying room connected with the hot air furnace through an air supply pipeline, wherein a conveying belt used for conveying tea leaves to be subjected to withering drying is arranged in the withering drying room; the conveying belt comprises conveying chains arranged at the two sides and a conveying plate in close adjacent arrangement between the conveying chains positioned at the two sides; an inner convex pin is arranged in each chain section hinging position of the conveying chain; the two side parts of the conveying plate are respectively provided with insertion pin grooves in matched connection with the inner convex pins; the two insertion pin grooves are positioned in the middle back positions of the advancing direction of the conveying plate; a conveying plate is arranged among the three inner convex pins arranged on the two chain sections. The transmission device has the advantages that in the transmission process, the friction force is small; the noise is reduced; the load is reduced; the motor can realize the positive and reverse rotation; the machinery stability is improved; the tea leaf clamping, bridging and tea hanging phenomena are basically avoided.

Description

[0001] Technical field: [0002] The invention relates to a transmission device and a working method of a chain plate type circulating tea withering dryer. [0003] Background technique: [0004] The tea withering dryer is used to wither and dry the tea leaves. There are many kinds of dryers at present. One of the traditional dryer transmission mechanisms is to fix one end and both sides of the conveying plate on the chain with a single pin. The other end is dragged by the guide rail, and there is an open groove at the end of the guide rail, and the conveying plate is dragged to the groove downward, and the dried product falls into the lower layer. The defect is: the conveying plate is dragged to the groove downward The impact of the conveying plate when turning over the plate will produce a lot of noise, and it is easy to cause the motor to reverse and crash, and if it is drying Wuyi Mountain tea, it is easy to cause tea jams and bridges at the turning plate. The bridging p...

[0004] The tea withering dryer is used to wither and dry the tea leaves. There are many kinds of dryers at present. One of the traditional dryer transmission mechanisms is to fix one end and both sides of the conveying plate on the chain with a single pin. The other end is dragged by the guide rail, and there is an open groove at the end of the guide rail, and the conveying plate is dragged to the groove downward, and the dried product falls into the lower layer. The defect is: the conveying plate is dragged to the groove downward The sound of the impact of the conveying plate when turning over the plate will produce a lot of noise, and it is easy to cause the motor to crash in reverse, and if it is drying Wuyishan tea, it is easy to cause tea and bridges at the turning plate

The bridging phenomenon makes the tea leaves fall directly to the bottom, forming a mixture of dry and wet tea leaves. The phenomenon of tea clamping also prevents the conveyor belt from turning over, causing the tea leaves to fall below the tea serving place outside the drying room.
