Description
Technical field
The present invention relates to a kind of lotus root digging harvester, specifically a kind of be suitable for complicated underwater environment from thrust lotus root digging harvester.
Background technology
At present for the lotus root of growth inside pond, field, need to excavate out by instrument because it is embedded in underground.Traditional by spade dredge get lotus root not only useless time, useless power, and often easily dig disconnected lotus rhizome, cause lotus rhizome to be worth and reduce.Also have at present and adopt water pump to wash away earth to get lotus root and substantially increase production efficiency, but to get lotus root less relative to the radius of clean-up for this mode, getting lotus root personnel needs to drag long water pipe and operates, and effect is unsatisfactory.Prior art the most advanced is dig lotus root by the special lotus root digging harvester with water pump, but this lotus root digging harvester is directly fetched water from pond due to water pump, and under pond water circumstance complication exist a large amount of foreign material often cause foreign material block water pump, even the fiber sundries such as cloth can cause water pump engine to burn by winding water impeller of pump main shaft, and causing the technical failure that lotus root digging harvester cannot work, the lotus root digging harvester worked under how providing a kind of structure to be simply suitable for complex environment is the object that those skilled in the art study always.
Chinese invention patent application numbers 201410369738.5 discloses a kind of automatic impurity removing lotus root digging harvester, regulate the adjusting device lower end in nozzle direction that two groups of dead levers and adjusting rod are set, each group dead lever and adjusting rod are all provided with multiple nozzle, between first group of dead lever and second group of adjusting rod, are provided with gangbar; Water tank is set to cylindrical shape, and the outer surface of water tank wall is provided with knot screen.Be provided with rotating shaft and rotating vane in water tank, the lower end of rotating shaft is provided with the scraper fixed mount of knot screen.This kind of lotus root digging harvester its remove foreign material mainly for be attached to water tank wall outer surface floating thing to carry out impurity elimination, the foreign material that water pump is water-bed in water absorption course are not carried out to the technical clarification removed or protect.
Summary of the invention
The invention provides that a kind of structure is simple, use safety is suitable for complicated underwater environment from thrust lotus root digging harvester.
A kind of be suitable for complicated underwater environment from thrust lotus root digging harvester, comprise buoyancy tank, buoyancy tank is provided with the engine driving water pump, engine spindle drives the vane rotary of water pump, engine spindle end is connected with knife bar, knife bar is provided with movable blades, in pump intake suction process, cutting and grinding are carried out to water-bed foreign material, prevent foreign material be wound around engine spindle and affect the safety of use.As further architectural feature pump intake, discoid fixed blade is installed, fixed blade is provided with the cutter groove run through, this kind of cutter groove structure is the technique complementary for movable blades, although the foreign material that movable blades cuts down diminish, but still there is certain shaped volumes, still the problem of water pump vane or water inlet blocking can be caused, and the cutter groove structure on fixed blade has carried out secondary cutting to the above-mentioned foreign material diminished in the process entering water pump, reach crushing effect, namely the blockage problem of traditional filter screen is avoided, also improve the safety in utilization of water pump.Described buoyancy tank comprises the workbench being provided with engine and the floating drum being located at workbench both sides is formed, and improves the stability that lotus root digging harvester is floating on the water surface.In order to realize digging lotus root and lotus root digging harvester from thrust performance, pump outlet is connected with plural playpipe by water knockout drum, and playpipe end is provided with sweptback shower nozzle.The high pressure water flow strikes mud that playpipe ejects makes lotus rhizome automatically float the technical purpose reaching and dig lotus root, and sweptback shower nozzle drives lotus root digging harvester by reaction force travels forward and achieve from pushing motion.
The first cutter groove, the second cutter groove, the 3rd cutter groove of different length is divided into as the preferred cutter groove of structure, first cutter groove is around fixed blade center evenly distributed formation first cutter ring, and the second cutter groove and the 3rd cutter groove interval are arranged and around fixed blade center evenly distributed formation second cutter ring.The structure that cooperatively interacts of the first cutter ring and the second cutter ring not only makes fixed blade can cut the foreign material of different size, and arranges by the second cutter groove and the 3rd cutter groove interval the distribution density that improve cutter groove, increases the smashing capability of fixed blade.
Described movable blades comprises the blade of three one, and blade cross section is isosceles trapezoid, and the upper base of isosceles trapezoid is provided with the semicircular structure of one, increases the area of cut of blade, prevents sheet blade too sharp, fracture and cause casualty accident.The first described cutter groove, the second cutter groove, the 3rd cutter groove are relative to the centroclinal setting of fixed blade, this angle of inclination is generally 15-60 degree, entrance angle when the swirling current formed after specifically rotating according to movable blades enter fixed blade is determined, to realize crushing effect better.
Described water knockout drum comprises hemispherical shell, and housing bottom connects pump outlet by pipeline, and case top is provided with plural tapping hole, and tapping hole connects playpipe by pipeline.The quantity of tapping hole is preferably 4, to obtain playpipe jet power advantageously.
Described water knockout drum case top center is provided with spreader, spreader entirety is pyramidal structure, and is provided with the splitter box of circular arc indent on surface, and uniform fluid flow is assigned in each tapping hole by splitter box, reach the uniformity requirement that playpipe sprays, avoid spraying inequality.
Described playpipe is installed on operation support by playpipe elevator, and operation support is fixedly connected with workbench, operation support is also provided with operator handle, is convenient to user and manipulates lotus root digging harvester.
Described playpipe elevator comprises the mounting bracket installing playpipe, and mounting bracket center is provided with thread bush, thread bush internal thread connecting screw rod, and screw tip is provided with handwheel, and bottom is connected and installed in the thrust bearing on operation support.This kind of playpipe elevator controls screw rod by handwheel and rotates, and the mounting bracket of drive installation playpipe moves up and down, and to control the spacing between playpipe and ground, the current realizing playpipe injection realize effective range.So-called effective range is exactly that namely the current of injection can not thrust lotus rhizome because of crossing near, also can not cannot wash mud open and causes digging lotus root failure because of crossing far away.
The present invention carries out secondary cutting by movable blades and with the fixed blade of cutter groove, in pump intake suction process, cutting and grinding are carried out to water-bed foreign material, namely avoid the blockage problem of traditional filter screen, also prevent foreign material be wound around engine spindle and clogging impeller and affect the safety of use.Arrange sweptback shower nozzle in addition to drive lotus root digging harvester by reaction force and travel forward in playpipe end and achieve from pushing motion.
