Bamboo breaking knife

Abstract

The invention discloses a bamboo breaking knife. One end of a main blade is fixed to a knife holder, the other end of the main blade is fixed to a centering shaft, multiple auxiliary blades are evenlydistributed on the knife holder along the axis line of the knife holder, the number of the auxiliary blades is consistent with the number of the main blades, the auxiliary blades are located over themain blades, the auxiliary blades and cutting edges of the main blades are located in the same plane, the bottoms of the auxiliary blades are hinged to the knife holder, multiple clamping grooves areformed in the side walls of the sides, away from the axis line of the knife holder, of the auxiliary blades, the auxiliary blades are sleeved with a hoop, multiple blocking columns are formed on theouter surfaces, away from the axis line of the knife holder, of the two ends of the hoop, check blocks are formed on the tops of the blocking columns, the blocking columns are sleeved with a sleeve ring, the top of bamboo is inserted on the centering shaft, bits of the auxiliary blades tighten the bamboo, the proper clamping grooves are selected for enabling the hoop to be sleeved with the clamping grooves of the auxiliary blades, when a bamboo breaking machine begins to work, the main blades are welded to the knife holder commonly, once the main blades are broken, the whole tool needs to be replaced, and the auxiliary blades can be replaced.

Description

technical field [0001] The invention relates to the technical field of bamboo and wood machinery equipment, in particular to a bamboo cutting knife. Background technique [0002] The bamboo-breaking knife is the core component in the bamboo-breaking machine. The quality of a bamboo-breaking knife determines the working efficiency of the bamboo-breaking machine. The existing bamboo-breaking knives are all cut by a knife. When encountering thick bamboo, the broken bamboo The cutting efficiency of the bamboo knife will become lower, and after cutting bamboo for a long time, the knife will be easily worn and broken to replace the whole broken bamboo knife, which will increase the cost, so at present there is a lack of a cutting pressure that can effectively relieve the blade, and The utility model relates to a bamboo-breaking knife which can improve the service life and cutting efficiency of the bamboo-breaking knife. Contents of the invention [0003] (1) Technical problems ...
