Description

Rubber picker working head

technical field

The utility model relates to the technical field of natural rubber rubber mining, in particular to a working head of a rubber mining machine.

Background technique

Natural rubber, together with steel, oil and coal, is called the four major industrial raw materials. It is an important raw material for national economic development and an important strategic material and industrial raw material for national defense.

Referring to Figure 8, natural rubber needs to be obtained by cutting the bark of the rubber tree by the working head of the rubber picking machine. In each process of cutting the bark, the rubber picking worker needs to hold the working head of the rubber picking machine inclined downward along the peripheral surface of the bark. (or sloping upwards) to cut off about half of the bark (the cutting plane is sloping downwards), and the arc-shaped cutting area (cutting surface) formed by each cutting along the circumferential surface of the bark sloping downwards (or sloping upwards) upward) is called "secant line", and the "secant line" area is the glue-out area. After multiple cuts along the "secant" of the rubber tree, the surface of the rubber tree forms a bare area (towards the side) from which the bark is planed, this area is called the "cut surface".

The axial depth of each cutting of the rubber tree (that is, the axial depth of each cut along the "secant line") will directly affect the rubber output of the rubber tree and the growth cycle of the rubber tree. If the axial depth of each time is too large, It will lead to waste of rubber tree wood, resulting in the need to give the rubber tree a longer growth time in order to allow the rubber tree to grow new bark for rubber harvesting again. If the axial depth of each cut is too small, the amount of glue in the newly cut "secant" area will be too low, resulting in low glue extraction efficiency.

The traditional rubber picking technology has high operational requirements and is not easy to learn and master. Cutting high-quality "secant lines" that meet the requirements of natural rubber rubber mining (reaching the technical level of first-class rubber mining workers) requires a long time of learning and practical operation, even one to two years.

The traditional natural rubber picking method is done manually. The rubber picking worker cuts the outer bark and bast of the rubber tree with a rubber picking knife, so that the latex flows out and is collected by a collecting device (plastic cup). The specific operation of the current traditional rubber picking method is that in the middle of the night, the rubber picking workers rush to the rubber plantation, hold the rubber picking knife in a similar reciprocating motion, and cut the outer bark and bast of the rubber tree piece by piece, one tree after another. Finish. The latex is ducted out of the rubber tree bark and flows drop by drop into the glue cup along the "secant" surface. After a certain period of time (the latex is no longer discharged), the rubber pickers collect the latex in the rubber cup on each rubber tree and send it to the rubber factory.

In order to ensure the output of latex and the quality of rubber (in line with the technical specifications for natural rubber rubber), it is necessary to cut in place "deep enough" without "damaging the tree" during the rubber picking operation, and to control the thickness of the bark each time it is cut. (that is, to control the consumption of the bark), the rubber picking workers must keep their eyes on the tip of the knife and pay full attention, cutting the bark one by one, and staring at the tip of the rubber picking knife that keeps moving for a long time at night. Tired eyes.

Different rubber picking frequencies and different rubber picking systems require different cutting bark thicknesses each time rubber picking, generally 1.4-2.5mm. If the thickness of the cutting bark is less than 1.4mm during rubber mining, because the "rubber plug" on the mouth of the latex tube cannot be removed, it will affect the rubber removal effect (that is, the latex output of this rubber mining is small and the economic benefit is poor). If the thickness of the cut bark is greater than 2.5 mm during rubber harvesting, the bark will be cut soon, because the discharge of natural rubber latex depends on the milk tube in the bark of the rubber tree. Without the bark, there is no natural rubber latex source. Greatly reduce the economic life of rubber trees (usually 20 to 30 years).

As the age of rubber picking workers increases, their eyes become presbyopic, their vision declines, and their physical strength declines. They become more and more incapable of rubber picking operations. More and more "damaged trees" are cut, and the thickness of the rubber tree bark is uneven. The cutting bark is too thin to meet the requirements, and the "rubber plug" on the mouth of the milk pipe cannot be removed, which affects the glue removal effect, and the latex yield of this rubber harvest is small. If the bark is too thick, although the "rubber plug" on the mouth of the milk duct is removed, the output of latex is guaranteed, but it exceeds the regulations. Each time the thickness of the bark is too large, it means that the rubber bark is rapidly reduced. As time goes by, there will be no bark to collect rubber, which will reduce the economic life of the rubber tree and bring economic losses to natural rubber production enterprises.

Compared with the prior art, the beneficial effects of the present invention are:

In the process of rubber harvesting, the purpose of precise bark cutting (controlling the thickness of the bark) is achieved under the premise of ensuring the output of the rubber latex. Saving the bark is to prolong the economic life of the rubber tree.

Reduce the labor intensity of rubber picking workers, improve work efficiency, reduce the burden on eyesight and energy of rubber picking workers, reduce the technical requirements for rubber picking, and shorten the training and learning time for new rubber picking workers. "Low secant line ("Yang Dao" means cutting layer by layer from top to bottom, suitable for lower bark positions, as shown in Figure 9), and cutting "Yin Dao" ("Yin Dao" means bottom-to-bottom cutting The upper layer is cut layer by layer, which is suitable for the higher bark position, as shown in Figure 10) and other rubber picking techniques (generally only 3-5 days, and the traditional rubber knife learning and training time is generally more than 20 days). One machine is multi-purpose and cost-effective.

The above-mentioned embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited by this. Any insubstantial changes and replacements made by those skilled in the art on the basis of the present invention belong to the scope of the present invention. The scope of protection of the utility model.
