Automatic rubber tapping machine and control method thereof

Abstract

The invention discloses an automatic rubber tapping machine which comprises a cutter assembly (1) and a first driving mechanism (3), and is characterized in that the cutter assembly (1) comprises a cutter rest (11) provided with a sliding groove (111); at least part of the sliding arm (12) is inserted into the sliding groove (111); the rotating seat (13) is rotatably mounted on the sliding arm (12); the tool bit (14), the guide piece (15) and the tool depth limiting guide plate (16) are all located on the rotating seat (13); the first elastic piece (17) can enable the sliding arm (12) to always have a trend of moving close to the rubber tree; and the second elastic piece (18) can enable the guide piece (15) positioned on the rotating seat (13) to always have a trend of abutting against the rubber tree. The invention further discloses a control method of the automatic rubber tapping machine. Compared with the prior art, the automatic rubber tapping machine is stable in channel cutting and capable of avoiding tool clamping.

Description

technical field [0001] The invention relates to the technical field of rubber tapping of agricultural machinery in the natural rubber industry, in particular to an automatic rubber tapping machine and a control method thereof. Background technique [0002] The economic benefits of rubber trees come from the latex output obtained from rubber tapping, and natural rubber is an important equipment material in various countries. How to extract latex from rubber trees simply and efficiently has always been an urgent problem for the rubber industry. Rubber trees can be tapped continuously for 30 to 40 years from planting to meeting the cutting requirements, and natural rubber is obtained by cutting the milk ducts in the bark of rubber trees. [0003] From the earliest method of using sharp tools to cut rubber trees to remove rubber to obtain latex, it was not until 1897 that the director of the Singapore Botanic Garden, Huang Dele, invented the rubber tree continuous rubber tapping...

AI Technical Summary

Problems solved by technology

[0010] Although a tree and a smart bionic rubber tapping machine currently on the market solve various problems of manual rubber tapping, due to the use of bionic artificial blades for tapping rubber, the operation requires a large The driving force and rubber tapping method are relatively simple, and the mechanical coordination of the whole machine is relatively complicated. The whole machine needs to be dismantled during maintenance, and the machine cost is relatively high. The on-hook requirements are relatively high, and the actual on-hook amount per acre of rubber forest land is relatively small, resulting in high costs and difficult promotion

[0011] The currently disclosed Chinese invention patent application CN104429813A, Chinese invention patent application CN106034980A, and Chinese invention patent application CN106718653A all use bionic artificial blades to tap rubber, and the rubber tapping mode is relatively single. When the blade taps rubber, it needs a large operating driving force to cut off the bark, which has relatively high requirements for the drive of the whole machine. It is easy to jam the knife when encountering tree tumors and depressions. In serious cases, it is easy to cause damage to the rubber tapping machine, and in light cases, it may cause missing cuts and affect the output. , it is often necessary to choose a good-looking rubber tree to install the machine. In fact, the amount of rubber trees that can be installed with machines is relatively small.

[0012] Chinese invention patent application CN111972250A adopts a double helix rail up and down in parallel layout, and the vertical tool pos...
