Description

A method of picking glue

technical field

The invention relates to a rubber mining method.

Background technique

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

Rubber mining is an important link in the production of natural rubber. It is a delicate and highly technical manual operation. The level of its level directly affects the output and sustainable production of rubber tree latex. Compared with a rubber picker with a good technical level and a poor technical level, the output difference between the two can reach 20% under the same conditions, and the difference in the economic life of rubber trees can reach more than 10 years.

The traditional rubber picking method is done manually. Specifically, the rubber picking workers use a rubber picking knife to cut grooves on the bark of the rubber tree, so that the latex in the inner layer of the bark flows out and is collected by a collection device; see Figure 3 It shows that in the actual operation of the current rubber picking method, the rubber picking workers use the reciprocating movement of the rubber picking knife to cut off the bark outside the inner layer of the yellow bark of the rubber tree one by one. Different rubber picking frequencies and systems require each cutting Bark thickness 1.4-2 mm, depth 1.4-2 mm from xylem. If the thickness of the bark is cut more than 2 millimeters each time, the bark will be cut soon, which will greatly reduce the economical efficiency of the rubber tree, that is, the economic life of the rubber tree will be shortened. If the cutting depth does not reach the specified range, some milk ducts in the bark will not be completely cut off, and the discharge of latex will be reduced, which will affect the yield. If the cutting depth exceeds the specified range and the tree is damaged, a pimple will grow at each damaged tree in the future, which will affect the growth of the bark and the latex output in the future.

In the process of peeling off the bark, the rubber picking workers should pay attention to the path and strength of the knife, and also pay attention to the four coordination of hands, feet, eyes and body (hold the rubber knife firmly in the hand, grasp the direction of the knife, so that the knife does not move) Swing up, down, left, and right, and move along one end of the notch to the other end of the notch. The feet should stand at a proper position away from the rubber tree, and move forward naturally. The eyes should be obliquely aimed at the receiving knife point, the body bends to the side and moves naturally with the eyes). Achieve "stable, accurate, light, fast and even". ("Steady" means holding the knife steadily, "Quasi" means receiving the knife accurately, "Light" means moving the knife lightly, "Fast" means fast speed, and "Even" means uniform depth, uniform knife connection, and uniform thickness and length of slices).

The work of picking rubber is a kind of work that consumes a lot of eyesight, energy and physical strength. Because it is difficult for human hands to control the strength and accuracy of the knife, and the technical difficulty is relatively high, it takes two years or more to train an excellent rubber picker.

Existing rubber mining method, owing to be on the rubber tree whole block bark (from outer skin to yellow skin inner layer place) is cut off, the damage to rubber tree itself is comparatively serious, and the rubber tree bast part that keeps after cutting is because thinner, is easily damaged. Pests, cold and other damage. When the phloem of the rubber tree grows to the bark thickness that can be used for re-harvesting, it will take 5-8 years of growth. The longer the growth period, the lower the economic benefits of the rubber tree; and, the existing rubber picking method is to reciprocate the knife along the length direction of the notch on the surface of the rubber tree, and when the knife is run, the blade needs to be downward And press down on the blade so that enough pressure is applied to the blade to ensure that the blade enters the bark for cutting. However, as the blade exerts pressure on the bark section, it rubs against the tissue structure of the bark section. In addition, when cutting the bark, the blade needs to be lifted upwards (the bark cannot be cut without such operation), so that the back side of the blade rubs against the tissue structure of the bark section, and such friction occurs once every time a piece of bark is cut. High friction force will usually cause deformation, narrowing or even blockage of milk duct opening, and reduce the rate of glue removal and rubber production.

Contents of the invention

Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a rubber picking method to ensure that the rubber tree has a large rubber yield, which can effectively deal with the damage to the new cut surface of the rubber tree after the rubber picking, such as diseases and insects, cold currents, etc. The time for the bark of the rubber tree to recover and reach the thickness required for rubber mining can improve economic benefits and reduce the labor intensity of rubber mining workers.

detailed description

Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

The rubber picking method of the present invention, comprises the steps:

Step A, cut part of the bark on the surface of the rubber tree to form a notch, in order to expose the bark outside the yellow bark inner layer of the rubber tree (generally the inside of the notch is 1.4-2 mm from the xylem of the rubber tree), for the subsequent bark The cutting provides the lower knife position, and the milk duct of the rubber tree bark is cut off at the lower edge of the notch;

Step B, utilize a rotating cutting knife to cut off the bark on the lower edge of the notch, as shown in Figure 1, this cutting knife comprises a first blade 11 and a second blade 12, and the second blade 12 is formed by the tail end of the first blade 11 Bending upwards, the tail end of the first blade 11 has a protruding portion, which protrudes beyond the second blade 12, that is to say, when the cutter rotates, the radius of rotation of the protruding portion on the first blade 11 is greater than The radius of rotation of the second blade 12, as shown in Figure 1, the radius of rotation of the protrusion is R, and the radius of rotation of the second blade 12 is r, wherein R is greater than r; when rotary cutting bark 21, the rotating mechanism can be utilized Drive the cutter to rotate, the first blade 11 cuts the bark along the extension direction of the notch, and the second blade 12 is used for cutting the bark between the cutting line of the first blade 11 and the lower edge of the notch and the bark from the inside of the yellow bark. The surface of the layer is peeled off and cut off (the peeling surface is preferably 1.4-2 mm from the xylem of the rubber tree);

Step C, repeat the rotary cutting process of the above-mentioned step B, from one end of the notch to the other end of the notch, the bark along the lower edge of the notch is sequentially rotary-cut, and a cutting process is completed. After cutting, the lower part of the notch is Moving down, the width of the notch increases;

Step D, repeat the above step C, follow the extension direction of the notch to complete the above-mentioned row knife process for many times, referring to Fig. 2, a plurality of protrusions 22 and grooves 23 are formed on the part of the rubber tree where the bark is cut off by the cutter, The raised portion 22 and the grooved portion 23 are arranged at intervals from top to bottom, and the above-mentioned raised portion 22 is a thinner part of the inner layer of bark remaining on the surface of the inner layer of yellow bark 24, which corresponds to the second blade. 12 cut off part, that is to say, the second blade 12 is not peeling off the bark 21 at the position where the bark 21 is combined with the inner layer of yellow bark 24, but retains a part of the bark in the inner layer of yellow bark 24 surface At the same time, grooves 23 are formed at the top and bottom of the remaining tissue structure, and at the grooves 23, the bark 21 is cut off by the first blade 12 from the position combined with the inner layer 24 of the yellow bark.

The above-mentioned method of the present invention can keep a part of the inner layer tissue structure of the bark in the cut-off part of the rubber tree, thereby ensuring that the newly cut surface of the rubber tree after rubber harvesting can effectively deal with damages such as diseases, insects, cold currents, etc., and simultaneously reduce the recovery of the rubber tree bark. growth time; and grooves are set on the inner tissue structure of the bark to ensure that the milk ducts are cut off, so that the latex can be discharged in time and smoothly; in addition, because the bark is cut by rotary cutting, the operation During the process, there is no need to apply a large downward force, so as to prevent the milk tube from being squeezed on the end face of the bark, resulting in narrowing or blockage of the tube opening, and improving the rubber production.

In step A, the notch is arranged obliquely on the surface of the rubber tree, and a plastic diversion groove consistent with the inclination direction of the notch is arranged under the notch, and the plastic diversion groove and the rubber tree bark are bonded with glue, and from the bottom of the notch One end extends to the other end below the notch, and a glue basin is arranged below the other end. Under normal circumstances, after the cutter cuts the bark, the latex flows smoothly down to the rubber splicing basin along the inclined notch. However, after the cut-off part of the rubber tree retains a part of the inner layer of the bark, the width of the notch becomes smaller, and the latex of some high-yield rubber trees will overflow from the notch due to poor flow and flow into the plastic diversion trough Then it flows to the glue basin, thus ensuring the collection of latex.

The included angle of the first blade and the second blade is 82-90 degree, like this, can be in the yellow bark inner layer 24 outer layers of the cut part of the rubber tree to keep the bark inner layer organization structure that thickness is suitable, preferably, the first The angle between the blade and the second blade is set at 85 degrees.

Those skilled in the art can make various other corresponding changes and deformations according to the above-described technical solutions and concepts, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
