Description
Technical field
The present invention relates to a kind of tropical crop-harvesting mechanism.Be specifically related to a kind of sisal harvester.
Background technology
Sisal hemp is the native fiber raw material of China's tool special advantage, strong but pliable in texture, springiness, pulling force that sisal fiber has are strong, anti tear, the characteristic such as wear-resisting, anticorrosion are that synthetic fibers are irreplaceable, especially sisal fiber have free from environmental pollution, not easily produce the advantage such as electrostatic, be widely used in manufacturing life and environmental supplies.Since accession to WTO, the demand of sisal fiber raw material is in ascendant trend always.At present, the domestic demand to sisal hemp goods is more than 80,000 tons, and global annual requirement is more than 700,000 tons, and world's sisal fiber gross yield only has about 300,000 tons, and therefore, sisal hemp insufficiency of supply-demand is larger.By affecting of sisal hemp outlet and pulling of the market price, the sisal hemp main producing regions such as current Guangdong, Guangxi are often average annual with the planting scale development more than 800 hectares, and turn to rural area to greatly develop with land reclamation and cultivation plantation for main by the past.The annual planting sisal hemp area in the whole nation is not less than 2000 hectares, and China's sisal hemp plantation had entered new developing period already.Sisal hemp life cycle is long, and the florescence is short, base of leaf meat, succulence, drought-enduring, slightly life, and water-saving, province's fertilizer, save production cost, and is a kind of crop being conducive to promoting resources saving agriculture technology, has positive effect to agricultural sustainable development.
At present, sisal harvester tool delayed becomes " bottleneck " of the scale of restriction sisal hemp, is also sisal hemp production mechanization key issue anxious to be resolved.This production link labour intensity is maximum, and harvest operation accounts for more than 60% of the amount of labour used in whole production process, so the results solving sisal hemp just solve the production mechanization of sisal hemp substantially.
Sisal harvester tool is blank out in China, and the sisal harvester of other country's research and development is all undesirable in the world, the report that so far there are no has sisal harvester product to come out abroad.
Summary of the invention
The present invention is a kind of sisal harvester, under the traction of tractor or other power, by the degree of freedom of adjustment cutter at four direction, automatically the sisal hemp leaf of maturation is cut, do not injure immature sisal hemp leaf simultaneously, the present invention is simple, convenient, and efficiency of crop is high, is a kind of desirable sisal harvester tool.
The technical solution adopted for the present invention to solve the technical problems is: it is provided with workbench, lifting hydraulic cylinder group is provided with below workbench, bearing support is provided with above workbench, support platform is provided with above bearing support, upper support platform is provided with positioning hydraulic cylinders and embraces cage fiber crops leaf hydraulic cylinder group, the piston rod embracing cage fiber crops leaf hydraulic cylinder group is connected with the intermediate support plates below upper support platform, intermediate support plates is provided with cutting liquid cylinder pressure group, and the piston rod of cutting liquid cylinder pressure group is connected with the lower support plate below intermediate support plates.
Described workbench is provided with horizon sensor, is also provided with longitudinal direction, lateral attitude adjustment hydraulic cylinder simultaneously.
The piston rod of described positioning hydraulic cylinders is connected with center-pole, and the lower end of center-pole is provided with Ma Yebao cage mechanism, and Ma Yebao cage mechanism is provided with numb leaf and embraces cage mechanism operating cover, and numb leaf is embraced cage mechanism operating cover and can centrally be slided up and down by bar.
Be provided with hollow sleeve below described intermediate support plates, lower support plate can slide up and down along hollow sleeve, and bar centered by hollow sleeve, hollow sleeve can centrally slide up and down by bar.
Described lower support plate bottom is provided with cutting knife, and cutting tool is equipped with in cutting knife bottom.
During work, first sisal harvester is dragged to by the sisal hemp plant for results by tractor or other power, by the height of lifting hydraulic cylinder group adjustment Ma Yebao cage mechanism, Shi Mayebao cage mechanism exceedes sisal hemp plant, control lifting hydraulic cylinder group by the horizon sensor on workbench simultaneously, workbench is made to be in level, by regulating the longitudinal direction on workbench, lateral attitude adjustment hydraulic cylinder, Shi Mayebao cage mechanism is in directly over sisal hemp plant, positioning hydraulic cylinder piston rod is released, Ma Yebao cage mechanism is driven to drop to appropriate location, then embrace cage fiber crops leaf hydraulic cylinder group piston rod to release, hollow sleeve is driven to move down by intermediate support plates, when hollow sleeve encounter numb leaf embrace cage mechanism operating cover continue to move down time, embrace cage mechanism operating cover due to numb leaf to move down, Shi Mayebao cage mechanism draws in, jejune numb leaf is embraced cage, at this moment cutting liquid cylinder pressure group piston rod is released, cutting knife is driven by lower support plate, the rapid incision of cutting tool, the numb leaf of maturation is cut down.Then cutting liquid cylinder pressure group, armful cage fiber crops leaf hydraulic cylinder group, positioning hydraulic cylinders return in succession, sisal harvester is dragged to by the sisal hemp plant of next strain for results by tractor or other power, repeats the above-mentioned course of work.
The invention has the beneficial effects as follows, sisal hemp is gathered in the crops and realizes mechanization, simple, convenient, efficiency of crop is high, greatly reduces sisal hemp results cost.
