Description

Technical Field

[0001] The utility model relates to the field of agricultural production, in particular to a connected-box decomposable tunnel drying box. Background Art

[0002] In Kalaqin Banner, Chifeng City, Inner Mongolia, there are more than 20 kinds of authentic Chinese medicinal materials, including Platycodon grandiflorum, Glehnia littoralis, Achyranthes bidentata, Astragalus membranaceus, Saposhnikovia divaricata, Atractylodes lancea, etc. Among them, the total output of Glehnia littoralis accounts for more than 80% of the national total output, and the total output of Platycodon grandiflorum accounts for 60% of the national total output. Kalaqin Banner is known as the "Hometown of Glehnia littoralis and Platycodon grandiflorum in China". After these Chinese medicinal materials are dug out from the land, they need to be processed and dried before they can be sold. In the north, most of them are planted by farmers, and they need to be air-dried and dried on bamboo or wooden drying racks. The drying racks are placed side by side in vacant spaces, which consumes a lot of space. Users who plant a lot cannot even dry them. The drying cycle is long (20-30 days), and Chinese medicinal materials cannot be sold during the high-price purchase period. When they are sold again after drying, the price drops sharply, reducing farmers' income. Farmers need a device that can dry a large amount of Chinese medicinal materials in a short time, reducing the drying cycle and drying space, thereby reducing time costs; farmers use the drying box for a short period of time each year (2-3 months), and farmers need a detachable, easy-to-move drying device that can enter and exit the rural gate at will. It can be quickly moved out and assembled for use, and can be easily disassembled and moved to the warehouse after use, without affecting farmers' use of the site for agricultural production at other times.

[0003] There are some drying machines on the market, which basically use three-phase electricity for electric heating and blowing. Farmers do not use three-phase electricity. For example, the electric heating blast drying box with publication number CN220750586U uses electric heating, dries a small amount, is large in size and cannot be moved, so it is not suitable for farmers. Summary of the invention

[0004] The purpose of the utility model is to help farmers solve the problem of drying a large amount of Chinese medicinal materials in a short time, reducing the drying cycle and site use, and reducing the time cost of farmers; the utility model provides a connected box decomposable tunnel drying box, which adopts tunnel-type unidirectional hot air drying, heats at one end, and the heat is dissipated into the entire drying channel through the finned tubes. The induced draft fan at the other end extracts the hot air in the channel, so that the hot air flow flows continuously in one direction, and at the same time takes away the water vapor volatilized during drying, so as to achieve the drying effect; in order to solve various problems caused by the large size and immobility of the drying box, the utility model adopts a connected box structure, which can be easily disassembled into separate boxes for movement, so that farmers can move quickly and reassemble them into one when they are moved to a suitable site.

[0011] The boxes are connected and fixed by bolts through box connecting plates, so that each box is connected into a whole;

[0012] The heating mode can be changed by replacing the coal-fired furnace and the finned tubes in the heating box with electrically heated finned tubes, and changing the coal-fired heating mode to an electrically heated heating mode.

[0013] The advantages of the utility model are:

[0014] 1. The utility model adopts tunnel-type one-way hot air drying, and uses the gravitational force of the induced draft fan to make the hot air flow from one end to the other end, while taking away the volatilized water vapor during drying, thereby achieving the drying effect;
