Abstract
Description
Technical Field
[0001] The utility model relates to a transmission mechanism, in particular to a transmission mechanism used in a material loader. Background Art
[0002] The preparation process of tobacco is relatively complicated. After the tobacco leaves are harvested, they need to be processed in different ways according to their characteristics and processing traditions. The purpose is to remove the green and excess moisture of the tobacco leaves for preservation; during the preparation process, the internal part is initially saccharified and matured to prepare for the complicated processing procedures later. There are several ways to process tobacco leaves: air-drying treatment method, the tobacco processed by this method is the most mellow. The tobacco leaves are first naturally air-dried in an open farm shed, and then placed in large sacks for fermentation; fermentation treatment changes the chemical composition of tobacco, making the flavor softer and reducing its nicotine content; sun-drying treatment method, tobacco leaves are fixed on rings and hung on the walls of the farm shed, using sunlight and natural wind to dry and mature. Almost all oriental tobacco is processed by this method; hot air pipe treatment method, after the tobacco leaves are harvested, they are immediately placed in a closed farm shed, and the hot air convection generated by the hot air pipe heating is used to dry the tobacco leaves. Due to the rapid drying process, the tobacco leaves turn yellow, and this method is often used to process blended tobacco; the open flame baking method, the tobacco processed by this method is the most intense. The tobacco leaves are hung over the open flame, and the rising thick smoke cooks the tobacco leaves and gives the tobacco a unique "smoky" flavor.
[0003] The existing tobacco leaf curing process requires the use of a tobacco curing room, in which shelves are arranged in pairs at equal heights. The tobacco leaves are clamped together by clamp rods in parallel. After the tobacco leaves are loaded into the tobacco curing room, the clamp rods are straddled to a pair of shelves, and the ends of the clamp rods can be slidably placed on the shelves. When loading tobacco leaves into the tobacco curing room, the clamp rods with tobacco leaves clamped on the shelves are pushed from the outside to the inside in sequence, so that the clamp rods gradually slide inward along the shelves, and the clamp rods are arranged in parallel on the shelves. In order to ensure the utilization rate of space, several layers of shelves are usually required in the tobacco curing room to store tobacco leaves in three dimensions. For high-rise tobacco shelves, if it is done by manpower, it will take a lot of physical strength, and the safety during the work process cannot be guaranteed. In addition, the working efficiency is not high, and the uniformity of the tobacco leaves in the tobacco curing room cannot be well guaranteed. Utility Model Content
