Abstract
The utility model provides a wheat head picking combine, belonging to an agricultural machine. The wheat head picking combine is mainly composed of a wheat head picking part, a threshing cleaning part, a haulm cutting part, and a power part. In harvesting time, the wheat heads are picked by a pivoted comb, and are threshed through a packing auger conveying blade type threshing device. Haulms are laid after cut by a cutting knife. The wheat head picking combine reduces unnecessary functions, increases production rate, and saves fuel. The wheat head picking combine is particularly suitable for harvesting wheat yielded more than 300 kg per mu.
Description
The utility model relates to an ear picking type combined wheat harvester, and it belongs to agricultural machinery.
The results operation of existing combine is: divide standing grain-pulling-stem stalk cutting-conveying-threshing and cleaning, the stem stalk under the cutting needs through threshing and cleaning, and the cane under the cutting needs to make the threshing power consumption big through threshing and cleaning, and productivity ratio is low, and fault is many.
The utility model is at above-mentioned weak point, and a kind of novel ear picking type combined wheat harvester of---threshing and cleaning---straw cutting of removing the wheatear head with broach is provided.
The utility model is finished like this, it matches with small tractor, the engine that utilizes tractor is as power, the fringe part is plucked in drive, the threshing and cleaning part, the work of straw cutting part, pluck the fringe part by plucking fringe, the cylinder power transmission shaft, turning cylinder, width of cloth dish, ratch, broach, capping, front shroud, back shroud constitutes, power transmission shaft is equipped with width of cloth dish, be connected with ratch and broach on the width of cloth dish, broach is the lance tooth that is connected as a single entity, the front end of capping is provided with cover plate, and is provided with the back reflection plate, and threshing and cleaning part is finished by center hulling disk and 8 threshing blades being installed in the hulling disk both sides.The straw cutting part adopts the cutting of the reciprocating of standard to realize.
Come the utility model is done further detailed description below in conjunction with embodiment and accompanying drawing.
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is the vertical view of accompanying drawing 1.
Accompanying drawing 3 is comb structure figure of the present utility model.
With reference to accompanying drawing, small-sized ear picking type combined wheat harvester and the supporting use of small tractor.It utilizes the engine of tractor as power source.This machine is plucked fringe part, threshing and cleaning part, straw cutting part and power transfer part and is constituted, power transfering part connects tractor clutch (17) by tractor engine (30) by belt and connects the left and right two ends of jackshaft (1), the right-hand member of jackshaft (1) connects blower fan belt wheel (14) by belt, the left end of jackshaft (1) connects straw cutting part (21) by belt, the straw cutting part adopts the reciprocating cutter of standard, pluck the straw behind the fringe, be cut the back lay.The left end of jackshaft (1) connects by belt to be plucked fringe cylinder power transmission shaft (7) and is connected ceding of Taiwan screw conveyor shaft (4).Pluck the fringe part by plucking fringe cylinder power transmission shaft (7), width of cloth dish (8), ratch (10), broach (11), capping (26) and header board (25), back reflection plate (24) constitutes, width of cloth dish (8) is installed plucking in the fringe cylinder transmission (7), on width of cloth dish (8), evenly be provided with 8 toothrow bars, ratch (10) is connected with broach (11), ratch (10) is 13-16 ℃ (best angle is 15 ℃) with the horizontal sextant angle β of width of cloth dish (8), broach (11) is the lance tooth of one, its space width α is 15-17mm, tooth depth b is 25-30mm, broach angle α is 14-16 ℃, and best angle is 15 ℃.The diameter phi of tooth root aperture is 3-4.5mm, and the linear velocity of crown is 10-13m/s.Front end in capping (26) is provided with front shroud (25), front shroud (25) is 65-85mm with the horizontal range h2 of crown, vertical range h1 apart from ceding of Taiwan bottom surface is 170-300mm, and back radiant panel (24) is 250-270mm apart from the vertical range h3 of ceding of Taiwan bottom surface.The threshing part is by spider (22) and be installed in 8 blades (5,12,23) that coil both sides, formation is plucked the wheat head that fringe part broach (11) is removed, drag to back cavity, through 8 high speed rotational blades to the wheat head threshing throw to back cavity, entering silo (27) matter will under the effect of fan outside air channel (28), (29) eliminating machine.Taiwan cut off and landing utilizes the hydraulic suspension (pulley wheel 20, steel wire rope 19) of tractor to adjust.
The novel ear picking type combined wheat harvester of the utility model design, it adopts the working procedure design of plucking fringe-threshing-stem stalk cutting, the stem stalk threshing useless power consumption that has overcome cutting type baby combine is big, productivity ratio is low, the defective that fault is many, because the stem stalk of this machine does not enter threshing, sheller unit load is little, productivity ratio height and threshing and cleaning structure reduce, compact integral structure, in light weight, oil consumption is low, and is applicable to the harvesting of per mu yield wheat more than 300 kilograms better.
