Description

Technical Field

[0001] The invention relates to the field of automated machinery, in particular to a profile-controlled depth ring-cutting, chip-removing and rubber-tapping device. Background Art

[0002] Natural rubber is an important strategic resource and an indispensable raw material in industrial production. It has been widely used in aerospace, healthcare, agriculture and other fields. However, the tapping of natural rubber is mainly done manually, which seriously restricts the production capacity of natural rubber. At present, there are two main types of mechanized tapping of natural rubber. One is the "one machine one tree" automatic tapping machine tied to the rubber tree. This model has the characteristics of lightness, simplicity and high working efficiency. However, due to factors such as structural design and cost control, this model does not have the ability to automatically adjust the depth of the tool. When the thickness of the rubber bark is thick, it is necessary to manually replace the tapping tool, which is a cumbersome process. The other is a "one machine multiple trees" tapping robot combined with a mobile chassis. The end of the robot has the advantages of imitating the artificial tapping spiral curve for tapping, and does not require manual installation. It is the main research direction in the future. However, the tapping mechanism of the tapping robot is relatively simple, the tapping depth is different, and the tapping quality during the tapping process is ignored, which makes the tapping operation of most automated tapping devices poor and tapping is easy to damage the bark.

[0003] In the actual rubber tapping process, in order to ensure the quality of rubber tapping and make the tapping depth consistent, a profiling mechanism is usually used. However, this method has high requirements on the straightness of the tree trunk. Due to the use of universal cutters, when the bark is thick and the pressure is high, the rubber tapping cutter will be entangled and sticky. Therefore, developing a tool that can refine rubber tapping, reduce rubber tapping cutter entanglement, and quickly replace the cutter suitable for the tree diameter has become a technical problem that technicians in this field need to solve urgently.
