A rubber picking method, a rubber picking processor and a rubber picking device

Abstract

The application discloses a latex collecting method, a latex collection processor and a latex collector; the latex collector comprises a casing, a needle drill, a rotation motor, a propulsion motor, a current sensor and a latex collection processor; the rotation motor drives the needle drill to rotate; the propulsion motor drives the needle drill to move back and forth; the current sensor is used for detecting the current value of the rotation motor; the latex collection processor can carry out analog-to-digital conversion according to the current value detected by the current sensor; the converted current value is compared with a set current threshold value, if the converted current value exceeds the set current threshold value, the propulsion motor is controlled to stop or fall back. The rotation motor drives the needle drill to work, and uses different current values for drilling into the bark and xylem; the current threshold value is determined by said current values used by the rotation motor; the needle drill drills into the xylem and stops to propel and drill, thus protecting the cambium layer from being damaged; the needle drill can easily drill into the rubber tree bark, so the latex tube can be less extruded, thus ensuring more latex flow amount.

Description

technical field [0001] The invention relates to the technical field of natural rubber latex harvesting, in particular to a rubber harvesting method. It also relates to a rubber harvesting processor and a rubber harvesting device based on the rubber harvesting method. Background technique [0002] Natural rubber is used as an economic crop, and its main economic harvest is latex. The traditional latex collection method is to manually cut the bark of 1 / 2 or 1 / 4 circumference along the spiral downward secant line, and the latex is extracted from the bark. After the milk tube flows out and collects in the rubber bowl, it is collected by the rubber worker and shipped to the processing plant. The traditional rubber tapping method has high technical requirements for rubber workers and high labor intensity. Careless operation can easily damage the cambium, and cutting the bark will cause great trauma to the rubber tree. In addition, smearing ethephon during production can easily le...

Problems solved by technology

The traditional rubber tapping method has high technical requirements for rubber workers and high labor intensity. Careless operation can easily damage the cambium, and cutting the bark will cause great trauma to the rubber tree. In addition, smearing ethephon during production can easily lead to dead bark of the rubber tree and no latex harvest. , resulting in a large loss in production

[0003] For this reason, some people have invented hammer-type or hand-pressed rubber-sampling needles, which can effectively reduce the technical difficulty and labor intensity of rubber-picking, but they cannot accurately control the needle depth, resulting in damage to the cambium during needle-punching rubber-picking. Coupled with the stimulation of ethephon, the dead skin rate of rubber trees has risen sharply

At the same time, when the rubber picking needle is pressed into the rubber bark, it will cause a large squeeze on the latex tube, resulting in a reduction in the amount of rubber discharged

In addition, under the action of external pressure and bark resistance, the rubber picking needle is easy to bend or break, so this technology is difficult to apply in production
