Embodiment
1 and 2 is known with reference to the accompanying drawings, and the present invention is specifically related to a kind of corn harvester, and the overall concrete structure of the ceding of Taiwan comprises and being made up of ceding of Taiwan frame 1, ceding of Taiwan auger 2, ear-picking unit 4, feeding unit 5 and outstanding cutting apparatus 3.
Main body frame of the present invention is ceding of Taiwan frame 1, and ceding of Taiwan frame 1 plays topmost supporting role, and other devices in the ceding of Taiwan are installed on ceding of Taiwan frame.The structural design of self uniqueness of ceding of Taiwan frame 1 in the present invention, is arranged in ceding of Taiwan auger 2, ear-picking unit 4, feeding unit 5 and outstanding cutting apparatus 3 on ceding of Taiwan frame, has accomplished the maximization of effective utilization to working space.
Can find out in fig. 3, stiff end and the car body 6 of ceding of Taiwan frame 1 are hinged, be provided with hydraulic cylinder 7 drive in hinged place.At ceding of Taiwan frame 1 and car body 6 link position, controlled by hydraulic cylinder 7, the angle adjustment to whole ceding of Taiwan frame 1 can be realized, distinctive angle of inclination alleviates the work load of hydraulic system and the overall length of vehicle, the ceding of Taiwan is enable to enter duty fast, and can adjust efficiently at any time at work, be adapted to any environment in field.
Ear-picking unit 4 is arranged on the dominant plane of ceding of Taiwan frame 1, is bolted, and is divided into left harvesting case and right harvesting case, and several groups of ear-picking unit 4 equidistantly arrangements in the plane.From transmission case export power, be connected with the ceding of Taiwan power shaft bearing between harvesting case 4-2 by universal coupling with spider, power shaft bearing by chain respectively by power transmission to harvesting case 4-2.The head of each snapping bar 4-1 all has group standing grain case 5-1 connected by splined shaft, and dialling standing grain case 5-1 inside is that two bevel gears coordinate, and realizes transmission commutation function, dials standing grain case 5-2 and be bolted on the subject plane of ceding of Taiwan frame 1.Along with the rotation of snapping bar 4-1, dial standing grain case 5-2 and obtain power accordingly, and pass through the output shaft of vertical direction with it, through sprocket wheel for rice-pulling chain 5-1 provides power.Outstanding cutting apparatus 3 is then positioned at the front lower place of ear-picking unit 4, relies on chain to carry out power transmission.Ear-picking unit 4 transmits power by chain to elevator and ceding of Taiwan auger 2.
With reference to the accompanying drawings 4, feeding unit 5 comprises rice-pulling chain 5-1, dials standing grain case 5-2, drive sprocket 5-3, driven sprocket 5-4 and tensioning apparatus 5-5, dialling standing grain case 5-2, to cross bolt fixing with on ceding of Taiwan frame 1 platform, dial standing grain case 5-2 after power shaft accepts power, through the speed change of casing internal gear, rotated by the standing grain drive sprocket 5-3 that dials on output shaft band moving axis.Rice-pulling chain 5-1 moves with uniform velocity along with dialling standing grain drive chain 5-3 wheel, and by group standing grain driven sprocket dialled on standing grain driven sprocket and tensioning apparatus 5-5 be bolted on ceding of Taiwan frame 1 platform, it is arranged in distance at an angle on ceding of Taiwan frame 1 platform.Maize straw, by moving tooth distinctive on chain, furthers and imports in snapping bar 4-2, carrying out ear harvesting operation by rice-pulling chain 5-1 from afar.Interlaced between moving tooth, improve group standing grain performance of plate on rice-pulling chain.On ceding of Taiwan outer cover, distinctive servicing unit will play the effect of importing, righting, lodging-prevention and shunting to the stalk of corn.Fruit ear is enable to carry out ear harvesting operation along with maize straw enters snapping bar smoothly.
Feeding unit in the present invention, through optimal design, operates steadily, noise is little.Rice-pulling chain 5-1 operating distance is short, efficiency is fast.Device is convenient to maintenance process simulation, and part replacement is convenient.This feeding unit through optimal design, have operate steadily, noise is little, be convenient to maintenance process simulation, it is convenient to change, can not cause damage to fruit ear, be not easily wound around the advantage of weeds.
Ear-picking unit 4 comprises harvesting case 4-2 and two snapping bar 4-1, two snapping bar 4-1 surface wrap spirality ribs, and be arranged in parallel, the right-hand member of two snapping bar 4-1 is all connected with harvesting case 4-2, and the left end of two snapping bar 4-1 connects with the joining place of feeding unit 5 respectively.
The main working parts of ear-picking unit 4 is snapping bar 4-1.The connected mode of snapping bar 4-1 and harvesting case 4-2 is the open type connected mode that pipe-sphere adds bearing pin.Maize straw, by relatively rotating between two rollers, to be pulled the disintegrating mechanism below snapping bar 4-1 by the rib on snapping bar 4-1 by snapping bar 4-1 continuously.When the fruit ear on stalk touches rib, fruit ear extrudes from stalk from fruit ear root by rib, and passes through the high speed rotation of snapping bar, tumbles the ceding of Taiwan auger 2 li of snapping bar right back.In this course of work, harvesting case passes through the gear graduation in casing, for snapping bar 4-1 provides the most efficient power.The open type connected mode of ear-picking unit 4, significantly increases the adaptability of the ceding of Taiwan to each department different cultivars, different agronomy.Dialling standing grain case by installing at harvesting head end, simplifying the transmission mechanism of the ceding of Taiwan.Distance between the rice-pulling chain meanwhile furthered and snapping bar, make to dial standing grain harvesting simpler, efficiency is higher.
Can see in figure 5, outstanding cutting apparatus 3 comprises stationary knife 3-1, moving knife 3-2 and axle 3-3, the circumferencial direction of cutter shaft 3-3 is provided with the moving knife 3-2 parallel with cutter shaft 3-3, the side of moving knife 3-2 is provided with the stationary knife 3-1 be fixed on ceding of Taiwan frame 1, stator by interval between moving knife 3-2 and axle 3-3 is fixed, and has the rotary-cut angle of 5-10 degree between described moving knife 3-2 and stationary knife 3-1.
Axle 3-3 is used for fixing moving knife, because cutter shaft is hollow-core construction, makes there is comparatively wide arc gap between moving knife and cutter shaft central siphon.This design be axle 3-3 operationally can from then on interstitial row cut weeds, the foreign material such as earth, the generation of the bad phenomenon such as not broken of being convenient to the chopping of moving knife 3-2, preventing causing stalk can't cut because foreign material block, cut.Be fixed on moving knife 3-2 fixed block by bolt moving knife, along with cutter shaft fast rotational and in stationary knife 3-1 produce to cutting, realize the chopping to maize straw with this.Cutter shaft pipe replaces old solid shafting by thick-walled tube, alleviates the weight of the ceding of Taiwan, and reduces cost.Stationary knife is bolted on ceding of Taiwan frame, is certain outstanding corner cut degree with moving knife.In the process that stalk is stretched by harvesting rib, realize rotating in air chopping downwards, thus reach the effect of saving power, reducing consumption.
The present invention is in normal work, milpa is delivered to snapping bar 4-1 port by forcing feeding system to be drawn in the ceding of Taiwan by feeding unit 5, by the auger on snapping bar 4-1, is furthered further by plant, enter the rib portion on snapping bar, by rib corn ear taken and be conveyed into elevator auger.And stalk is stretched in order by rib, deliver to outstanding cutting apparatus 3 downwards, maize straw cuts off and the section of being chopped into by the rotation moving knife via outstanding cutting apparatus 3.
In the present invention when specifically using, ear-picking unit 4 wherein, feeding unit 5 and outstanding cutting apparatus 3 also can replace with existing conventional mechanism, such as feeding unit 5 can be rotated relatively by two horizontal positioned gear sheet, realize the feeding of stalk, ear-picking unit 4 utilizes two to cut curved harvesting plate, can realize winning corncob, outstanding cutting apparatus 3 utilizes the cutter sweep of the compositions such as cutter, chain target, screw feeder, roll, realizes crushed stalk.Above-mentioned concrete structure can with reference to prior art.
