AI Technical Summary

Technical Problem

Traditional flat wooden shovels are difficult to use effectively to concentrate force during the stem-breaking process, resulting in high labor intensity and low efficiency for workers, and uneven heat dissipation affects the fermentation effect.

Method used

A novel sorghum stalk breaking shovel is designed, which adds a stalk breaking sharp part (such as a triangular pyramid) and an arc-shaped flow guide part to the main body of the shovel board. The sharp part concentrates stress to cut into the sorghum stalks, and the arc-shaped flow guide part guides the mash to roll, forming a compound motion to improve the stalk breaking efficiency and heat dissipation effect.

Benefits of technology

It significantly reduces the driving force required for breaking the stems, reduces the labor intensity of workers, improves the efficiency of breaking the stems, and promotes uniform heat dissipation of the mash through compound movement, thereby improving the fermentation quality.

Abstract

The utility model belongs to the technical field of Maotai-flavor liquor production tools, and particularly relates to a novel stem breaking wooden shovel for Maotai-flavor liquor production, which comprises a shovel plate main body, the upper surface of the shovel plate main body is a stem breaking working surface; the stem breaking sharp part is arranged at the central position of the front end of the stem breaking working surface; and the handle is arranged on the shovel plate main body and is used for operating the shovel plate main body in a handheld manner. The stalk breaking sharp part is additionally arranged on the shovel plate body, the stalk breaking sharp part is provided with a sharp vertex angle, force can be concentrated to rapidly cut into sorghum stalks, and compared with a traditional wooden shovel plane, the acting force needed by stalk breaking is greatly reduced, the labor intensity of workers is greatly relieved, and the stalk breaking efficiency is improved.
