Automatic rubber tapping machine profiling and cutting mechanism for rubber trees

Abstract

The invention belongs to the field of agricultural or forestry machines, and relates to an automatic rubber tapping machine profiling and cutting mechanism for rubber trees. The mechanism comprises aprofiling mechanism and a cutting mechanism, the profiling mechanism is composed of a numerical control three-axis sliding table, and the spatial three-dimensional profiling function is achieved by controlling rotation of a stepping motor. The cutting mechanism is installed on the profiling mechanism and is composed of a cutting device and a limiting device, the cutting device achieves cutting bycontrolling rotation of the motor, the limiting device achieves control over the cutting depth through bolt fixation, and therefore synchronous profiling and cutting of the whole rubber tapping process are achieved. The mechanism has the advantages of being simple in structure, convenient and reliable to control and the like, rubber tapping automation is achieved, the rubber tapping efficiency andquality are effectively improved, the defect existing in a traditional rubber tapping mode is overcome, and the requirement for the market can be met.

Description

technical field [0001] The invention belongs to the field of agricultural or forestry machinery and is used for harvesting natural rubber tree latex, in particular to a profiling and cutting mechanism for a rubber tree automatic tapping machine. Background technique [0002] Natural rubber is an important equipment material. It has high elasticity at room temperature, slightly plastic, very good mechanical strength, low hysteresis loss, low heat generation during multiple deformations, and good flex resistance. Because it is a non-polar material and has good electrical insulation performance, it is widely used. With the continuous development of industry, the demand for natural rubber continues to increase. Natural rubber is obtained by cutting the latex tubes of rubber trees. The advantages and disadvantages of rubber tapping machinery directly affect rubber production. The shape of the trunk of the rubber tree is similar to an ellipse, and the surface of the bark is uneve...

AI Technical Summary

Problems solved by technology

If there is no profiling mechanism, the cutting depth of the rubber tree in some places is too shallow and the latex tube is not cut, and the output is reduced; in some places, the cutting is too deep and the rubber tree is damaged.

[0003] Natural rubber mainly comes from the latex in the latex duct cells of the bark. When tapping the rubber, a part of the bark is cut off with a rubber knife to obtain the latex. The tapping depth is an important factor affecting the latex yield. If the tapping depth is too shallow or too deep, it will reach It does not meet the production requirements, if it is too shallow, it will not meet the production requirements, and if it is too deep, it will cause damage to the tree body. When the damage is serious, dead skin may occur, which will cause the gum tree to stop degluing.
