Spiral paring knife for rapidly paring large quantities of pineapples applicable to canning factory

Abstract

The invention discloses a spiral paring knife for rapidly paring large quantities of pineapples applicable to a canning factory. The manual spiral paring knife comprises a first screw blade, a second arc blade, a knife rod and a hand wheel, and is mainly characterized in that a No. 2 Morse taper shank which is matched with a taper hole of a drill sleeve of a drilling machine is arranged at the right end of the knife rod; a neck part is arranged at the left end of the No. 2 Morse taper shank, and a tool withdrawal groove is formed in the left end of the neck part. When the pineapples are required to be pared, the No. 2 Morse taper shank of the spiral paring knife is inserted into the taper hole of the drill sleeve of the drilling machine to be propped tightly, and then can cooperate with the drilling machine to rapidly pare the pineapples. According to the invention, the functions of the manual spiral paring knife are kept, furthermore, the spiral paring knife can cooperate with the taper hole of the drill sleeve of the drilling machine, so that the pineapples are pared more simply, quickly and easily to greatly reduce the labor intensity and more significantly improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of knives, in particular to a helical cutting knife suitable for quickly cutting large quantities of pineapples in a cannery. Background technique [0002] The outer skin of the pineapple is currently cut off with an ordinary knife, and the "inner thorn" of the pineapple is currently dug with a V-shaped knife or cut off with a sickle-shaped curved knife. The pineapples are even more miserable, seriously affecting production efficiency. [0003] On October 10, 2016, the inventor submitted an invention patent application called "A Manual Spiral Cutter for Quickly Cutting Pineapple", the application number is 201610883349.3, the main features are: The end of the left end is provided with a first helical blade with an integrated structure for fast helical cutting of pineapples. The second circular-arc blade for quickly removing pineapple skin and "inner thorns", the second circular-arc blade and the first heli...
