Description

Technical Field

[0001] The utility model relates to the technical field of bamboo splitting, in particular to an inner rotating drill bit of a bamboo splitting machine. Background Art

[0002] Bamboo splitting machine is a commonly used equipment in the primary processing of bamboo. It can process bamboo into bamboo strips, which improves the efficiency of manual bamboo splitting. There are many different types of bamboo splitting machines on the market, but the degree of automation of these bamboo splitting machines is still relatively low, and there are still many processes that require manual operation, low efficiency, and high production costs. The degree of automation of bamboo splitting machines in the prior art is not high. The bamboo splitting work is completed by human-machine cooperation. The processed bamboo segment is picked up by the operator, and one end of the bamboo segment is placed on the bamboo support seat of the bamboo splitting machine. At the same time, the bamboo segment and the bamboo splitting knife disk must be aligned, and the driving device of the bamboo support seat is started to push the bamboo segment toward the bamboo splitting knife disk until the other end of the bamboo segment contacts and is cut by the blade on the bamboo splitting knife disk. After cutting a section, the operator can release the hand holding the bamboo section, turn around and pick up another bamboo section to repeat the previous operation; the bamboo sections are thick and thin, and the width of the processed bamboo pieces has a required range. Therefore, when the diameter of the bamboo section changes, the bamboo breaking knife disc on the knife holder must be replaced manually. It can be seen that in the bamboo breaking process of the existing bamboo breaking machine, the proportion of manual operation is too large, the labor intensity of the operator is high, and there are many repetitive actions. The technical requirements for the workers are high, and the cost of labor investment by the enterprise is too high; it cannot be guaranteed that the moving direction of the bamboo breaking knife will not change, and the cut surface cannot be guaranteed to be flat. The bamboo breaking knife is easy to shake, resulting in wrinkles on the cut surface, and the processing quality of bamboo and wood handicrafts is poor.

[0003] In the prior art, for example, Chinese patent CN201010298382.2 discloses a bamboo-breaking tool with a replaceable blade, comprising a bamboo-breaking tool holder, a vertical inner segment removal impactor installed at the center of the bamboo-breaking tool holder, a front end of the inner segment removal impactor provided with a bumper, a bamboo-breaking blade fixing device installed on the bamboo-breaking tool holder, a detachable bamboo-breaking blade connected to the bamboo-breaking blade fixing device, and the other end of the bamboo-breaking blade clamped in the groove of the inner segment removal impactor. The bamboo-breaking tool does not have a rotary bamboo-breaking function, and has a low bamboo-breaking efficiency. Summary of the invention
