Description
Technical Field
The utility model relates to a natural rubber industry agricultural machine rubber tapping technical field specifically indicates an automatic rubber tapping machine.
Background
The economic benefit of the rubber trees comes from the yield of the latex obtained by rubber tapping, while natural rubber is an important equipment material in various countries, and how to simply and efficiently extract the latex from the rubber trees is a problem which is urgently needed to be solved by the rubber industry. Rubber trees can be cut continuously for thirty to forty years from planting to meeting the cutting requirements, while natural rubber is obtained by cutting the mammary ducts in the rubber tree skin.
The latex is obtained by the method of cutting the rubber trees and discharging the rubber by using a sharp tool at the earliest, and the rubber yield is greatly improved only by the continuous rubber tapping method of the rubber trees invented by Huangdelier, the owner of the Singapore vegetable garden, in 1897. The rubber tapping method is continuously developed in the following 120 years, the common rubber tapping methods of a full-female cutter, a full-male cutter and the like are adopted at present, the rubber tapping technical requirement is high, a skilled rubber worker needs one month or more for cultivation, and a large amount of technical training cost is required.
The rubber trees meeting the cutting requirements can be cut in 280 days in one year, each tree needs to be cut 110 times, almost 2 to 3 days are cut once, the labor investment of a rubber tapping worker and the like accounts for more than 70 percent of the total investment of the whole production latex, in the rubber tapping period, because the rubber discharging latex pipe in the rubber tree is at the lowest air temperature every day, the swelling pressure in the rubber tree is high, the flowing latex liquid is solidified due to low temperature and the rubber discharging time is prolonged, the tree cutting needs to be started when the air temperature is low at 2 o' clock every morning, the tree cutting is carried out every 3 hours, 4 to 5 hours are consumed from the beginning of the first tree to the end of the cutting, the manual rubber cutting can only cut about 500 trees every day due to physical consumption, frequent stoop and the like, the rubber tapping cost is high, the field operation environment is very harsh at night, and frequent various body discomfort can be caused due to frequent disturbance of various mosquitoes and long-time stoop operation. The rubber tapping process can also cause great influence due to the interference of rainwater, certain natural rubber producing areas suffer from the duration of wind and rain in the seasons of up to 6 months every year, so that the trip of rubber tapping personnel is inconvenient, the rubber tapping frequency is reduced, artificial rubber tapping is performed for 65-80 times per plant per year, the number of times of manual rubber tapping is lower than that of normal standard 110 times, and the number of times of cutter losing is large, so that the yield is too low.
However, a skilled glue worker needs one month or more, a large amount of technical training cost is invested, and under the background that the current labor is increasingly tense, the labor cost is greatly increased, young people do not want to cut glue and the market quotation is not good, a production enterprise can not lay out glue, the embarrassment situation that glue cannot be cut and glue is not cut is caused, and great loss is caused to production.
In order to improve the tapping efficiency, reduce the tapping technology and reduce the labor of the tapping tool, various tapping tools such as a traditional push-type tapping tool, an electric tapping tool, an automatic walking robot tapping machine and the like are also provided on the tapping tool.
The electric tapping knife can only reduce the tapping technical requirements and cannot replace the manual labor, and the daily early morning work and long-time manual operation cannot be avoided.
Although the automatic walking robot rubber tapping replaces the manual work, due to the terrain limitation of the rubber forest and the different appearance states of each tree, the cutting path needs to be repositioned and searched before the rubber tapping of each tree, so that the operation is slow, the efficiency is low, and the popularization cannot be realized.
The natural rubber belongs to agricultural properties before primary processing in a rubber tapping stage, the rubber after tapping enters the industrial field after being fed into a factory for processing, the special properties determine the use requirements and the facing groups of rubber tapping machines, and the future of the rubber tapping machines is determined by the requirements of durability and convenient maintenance on the basis of low cost.
Although various problems of manual rubber tapping have been solved to bionical rubber tapping machine of intelligence of a tree on the market at present, owing to adopt bionical artifical blade rubber tapping, the operation needs great drive power, and the rubber tapping mode is more single, complete machine mechanical cooperation is more complicated, need the complete machine to demolish during the maintenance, the higher maintenance of machine cost is troublesome, it is irregular to meet the tree outward appearance, the crown arch, unable normal use such as sunken, it is higher to hang the machine requirement of rubber tree, the actual on-hook volume of a mu rubber forest land is less etc. cause the cost too high and lead to promoting difficult phenomenon.
The currently disclosed Chinese patent application CN104429813A, chinese patent application CN106034980A and Chinese patent application CN106718653A all adopt bionic artificial blades for rubber tapping, the rubber tapping mode is single, as the bionic blades need larger operation driving force to cut off barks when tapping rubber, the driving requirement on the whole machine is higher, the cutters are easy to clamp when the burrs and the recesses are encountered, the rubber tapping machine is easy to damage when the defects are serious, the output is influenced by skip cutting when the defects are caused by light persons, rubber trees with good quality are often required to be selected to install the machine, and the quantity of machines which can be installed by one rubber forest is less in practice.
The Chinese patent application CN111972250A adopts a vertical parallel arrangement of double spiral tracks, a motor of a vertical tool rest assembly connected in the middle drives a screw rod to drive an upper driving gear and a lower driving gear to run along the upper spiral track and the lower spiral track, and drives the tool rest assembly to complete transverse tapping and vertical line changing.
Although the chinese patent application CN109924100A adopts the electric rotary cutting disc blade, the diameter of the disc surface of the rotary blade is large, and the situation that the cutting cannot be achieved due to the fact that the rotary blade cannot touch the concave part is encountered.
Although the rubber tree is not damaged by fixing the machine by adopting the binding belt, the stability is poor, the firmness and the service life of the whole machine are determined by the quality of the binding belt, and the cost is invisibly increased. In addition, the rubber tapping machine is large in integration due to the fact that complex mechanical gear matching is needed among all parts, and the parts are required to be dismounted and maintained after being in a problem and cannot be replaced on site, so that the operation and maintenance cost is high, and the rubber tapping machine cannot be popularized and used in a large area all the time.
