Description

TECHNICAL FIELD

[0001] The utility model relates to bamboo sawing field especially a blocking mechanism and bamboo cutting device. BACKGROUND

[0002] The existing bamboo cutting device cuts bamboo, and the last section material does not meet the required size in diameter, so it is usually regarded as waste. After the existing bamboo sawing machine cuts the bamboo, the last section material needs to be manually removed. Since the last section material also has a certain weight, it is time-consuming and laborious to unload the last section material from the bamboo sawing machine, and continuous cutting cannot be realized. In addition, during the cutting process of the existing bamboo sawing machine, if the cut bamboo section does not meet the requirements, the unqualified bamboo section will fall into the discharge chute together with the qualified bamboo section for collection, and subsequent manual sorting is required, affecting production efficiency.

[0003] Some existing technologies set a blocking mechanism at the discharge end of the bamboo cutting device to sense the position of the bamboo and control the automatic discharge of the discharge mechanism. However, the blocking mechanism in the existing bamboo cutting device has a spring inside and uses the spring to push the blocking piece back to its original position. Although the spring force can push the blocking piece back to its original position, the spring force will cause the blocking piece to shake during the resetting process, resulting in poor stability of the blocking piece and easy triggering of the sensing piece of the blocking mechanism at inappropriate times.

[0019] The triggering component is hinged to the sensing end of the displacement sensor, and the triggering component has a triggering end;
