Sealed and sanitary composite spade

Abstract

The invention discloses a sealed and sanitary composite spade. The sealed and sanitary composite spade comprises a space handle, a connection short pipe and a spade body. The connection short pipe comprises a thread connection section, a tapered connection section and a cylindrical pipe section which are sequentially arranged, wherein the external diameter of the tapered connection section is gradually increased in the direction from the thread connection section to the cylindrical pipe section, the thread connection section is in threaded connection with an internal thread of the spade handle, the tapered connection section extends into the spade handle along with screwing of the threads, and the connection end of the cylindrical pipe section is connected with the connection end of the spade body. According to the sealed and sanitary composite spade, by means of the arrangement of the thread connection section and the tapered connection section of the connection short pipe, fasteningconnection between the connection short pipe and a carbon fiber pipe is guaranteed while the strength of the carbon fiber pipe is effectively guaranteed; the carbon fiber pipe is selected as a spade pipe, and the weight of the whole spade is reduced while the strength of the spade handle is enhanced; the spade body, the connection short pipe and the spade handle are connected into a whole of an internally-sealed structure, internal bacterium breeding pollution is effectively prevented, and washing and arranging are facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural tools, in particular to a sealed and hygienic composite shovel. Background technique [0002] During the winemaking process, it is necessary to use shovels to turn over the cellar, clean the wine cellar, manually raise the steamer, lower the sand, artificially moisten the grain, manually mix, clear and transport the grape mash, and clean up the grape pomace. The traditional shovel handle is a wooden handle. It is relatively humid, and the wooden handle often rots or deteriorates after being used for a period of time. On the one hand, it is easy to greatly reduce the strength of the shovel handle, or even break it. On the other hand, the moisture deterioration of the handle directly affects the quality of the finished wine. The body cannot be sealed and connected, and it will inevitably produce a large number of bacteria during the long-term exposure to the wine-making environment, which will ...

[0002] During the winemaking process, it is necessary to use shovels to turn over the cellar, clean the wine cellar, manually raise the steamer, lower the sand, artificially moisten the grain, manually mix, clear and transport the grape mash, and clean up the grape pomace. The traditional shovel handle is a wooden handle. It is relatively humid, and the wooden handle often rots or deteriorates after being used for a period of time. On the one hand, it is easy to greatly reduce the strength of the shovel handle, or even break it. On the other hand, the moisture deterioration of the handle directly affects the quality of the finished wine. The body cannot be sealed and connected. Long-term exposure to the wine-making environment will inevitably produce a large number of bacteria during use, which also has an adverse effect on the wine-making process.
