Description

Technical Field

[0001] The present application relates to the technical field of rubber tapping machines, and in particular to a portable electric rubber tapping machine. Background Art

[0002] Rubber tapping refers to the process of collecting the rubber juice from rubber trees. First, the outer bark and bast of the rubber tree need to be cut, and then the latex will flow out. Traditional rubber tapping knives are manually operated by personnel for cutting, which is very laborious and inefficient. Moreover, the noise emitted from the rubber tapping knife from the time it is started to the time before the rubber tapping operation is implemented is particularly loud. Although the electric rubber tapping machine on the market at this stage saves the manual power of the operator, the connecting rod used to install the cutter head in the electric rubber tapping machine in the prior art will rotate circumferentially when it moves, and the supporting strength of the connecting piece between the connection and the housing is insufficient, thereby affecting the cutting accuracy and work efficiency of the rubber tapping machine.

This design further improves the mechanical strength of the sleeves, and the sleeve connecting the two sleeves further improves the straightness of the guide rod when moving in the sleeve.

[0044] refer to Figure 6 In a specific embodiment, a guide hole 321 adapted to the guide rod 31 is arranged on the sleeve 32, and the radial cross-section of the guide hole has a pair of relatively arranged straight line structures 3211, a pair of relatively arranged arc structures 3212, and a transition portion 3213 located at the intersection of the straight line structure 3211 and the arc structure 3212. The transition portion 3213 is specifically manifested in the sleeve 32 as a groove 322 extending along the axis of the sleeve. In this embodiment, the radial cross-sectional shape of the guide hole 321 is similar to the radial cross-sectional shape of the guide rod 31, and a straight line structure 3211 matched with the parallel surface 311 of the guide rod 31 is provided. This design avoids circumferential torsion of the guide rod 31 in the guide hole 321. At the same time, the transition portion 3213 is provided in this embodiment to reduce the friction between the intersection of the parallel surface 311 of the guide rod 31 and the arc surface 312 and the guide hole 321, thereby improving the service life of the sleeve 32 and the guide rod 31.

Guide blocks 12 are arranged on both sides of the guide rod 31 in the shell 10, and each guide block 12 is arranged with a slide groove 121 adapted to the slide bar 31, that is, the guide rod 31 can slide in the shell 10 along the slide groove 121. Specifically, the slide bar 35 is cylindrical, and a first through hole 313 is arranged on the guide rod 31. The slide bar 35 passes through the first through hole 313 and is slidably set in the slide groove 121.

The cam 41 is arranged at the output end of the driving motor 22, the connecting portion 42 is arranged on the sliding rod 35, and the connecting portion 42 is symmetrically arranged about the guide rod 31. The elastic reset member 43 is sleeved on the guide rod and is located between the two shaft sleeves 32. The elastic reset member 43 is specifically a reset spring. In actual use, when the cutter head of the rubber tapping machine abuts against the rubber tree, under the action of the abutting force between the cutter head and the rubber cutter, the connecting portion 42 abuts against the cam 41, and the rotation of the cam 41 drives the connecting portion 42 and the guide rod 31 to make a linear motion, thereby driving the cutter head to make a linear motion.
