Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1～Fig. 4, from the figure as can be seen, the utility model single file rice wheat threshing prior to cutting combine comprises frame 10, road wheel 11, power set 12, threshing cylinder 7, divides standing grain device 1, holds up standing grain piece 14, front end grain lifter 2, horizontal grain lifter 15, vibratory sieve 4, spiral to stir cage 3, disc cutter 9, arc notch board 5 and fan 8.Frame 10 is as the basis of this grain header, and above-mentioned each parts all are mounted on the frame.Frame 10 is provided with the case 6 that prevents that the seed from splashing, and road wheel 11 is positioned at frame 10 postmedians, and power set 12 are positioned at frame 10 ends.Threshing cylinder 7 is installed on and is arranged in case 6 and rotatable under power set 12 drive in the frame 10, and its axis is parallel with direction of advance.Threshing cylinder 7 is made of the conical surface part of front end and the cylindrical portions may at rear portion, is provided with some threshing teeth on the cylindrical portions may outer wall, and the conical surface is provided with guiding spiral 13.Other each position component, structure and effect are described below:
Divide standing grain device 1---divide standing grain device 1 be positioned at whole frame 10 foremost, be used for separately the rice wheat of different rows, actual is current harvesting row to be gone with next harvesting separate.Divide standing grain device 1 to form by left and right sides nearside divider, between leave the spacing that only allows the due-in bar that cuts rice and wheat of delegation pass through, realize that single file gathers in.Left and right sides nearside divider front end is the tip, and the nearside divider on the left side also opens laterally, sees Fig. 2, and such structure is more conducive to the rice wheat of different rows separately, for the separation of toppling over, the rice wheat of arrangement at random also can be realized ideal.
Front end grain lifter 2 and hold up standing grain piece 14---front end grain lifter 2 and hold up standing grain piece 14 to be positioned at branch standing grain device 1 rear, threshing cylinder 7 side the place aheads, front end grain lifter 2 uses with holding up 14 pairings of standing grain piece, both are parallel, front end grain lifter 2 in the outer part, hold up standing grain piece 14 in the inner part, see Fig. 2 and Fig. 4, the bar stem is from front end grain lifter 2 and hold up between the standing grain piece 14 and pass through.Front end grain lifter 2 recedes 13 inclinations of the guiding spiral on the threshing cylinder conical surface simultaneously so that front end grain lifter 2 docks with guiding spiral 13 with the upper end of holding up standing grain piece 14, is used for and will imports the guiding spiral to be similar to tangent mode after the straw fringe portion pressure deflection.
Described front end grain lifter and horizontal grain lifter comprise carrier chain and some grain lifting teeths of being located on the carrier chain, and carrier chain is driven by power set, and carrier chain drives grain lifting teeth and do not stop to move, and by grain lifting teeth straw is stirred to (shown in Figure 2 towards the right) backwards.From direction shown in Figure 2, the carrier chain on front end grain lifter and the horizontal grain lifter all is to do to turn clockwise.Front end grain lifter and horizontal grain lifter are provided with housing, and housing exposes the grain lifting teeth of stirring straw, and all the other teeth then are hidden in the housing.If there is not grain lifting teeth that straw is stirred towards the opposite direction of direction of advancing, straw will be driven beat forward, and the standing grain fringe just can not be well and the effect of threshing tooth, is unfavorable for threshing.
Arc notch board 5---the structure of arc notch board 5 is seen Fig. 3, and arc notch board 5 is provided with some grids, and it is positioned under the threshing cylinder 7 and keeps suitable spacing with it.This spacing can make the disconnected fringe head that drops on the notch board continue to be rubbed by threshing cylinder, realizes the effect of further threshing.
Vibratory sieve 4---see Fig. 1 and Fig. 3, vibratory sieve 4 is positioned at the grain seed that is used for producing after the notch board coarse filtration under the arc notch board 5 further to be separated with foreign material, and it is driven by power set 12 and produces vibration.
Spiral stirs cage 3---and see Fig. 1 and Fig. 3, spiral stirs cage 3 and is positioned under the vibratory sieve 4, and it drive to be rotated by power set, and the helicla flute in rotation process on it is used for a grain seed band that drops on the case bottom delivered to puts out cereal mouthful and collected by gathering unit.
Described case 6 lower part the right and lefts shrink and form the deep-slotted chip breaker of collecting seed in the bottom to the centre, and it is corresponding that the shape of deep-slotted chip breaker and spiral stir cage, sees Fig. 3, and it is more thorough that this structure makes spiral stir the cage feeding.
Described power set comprise the vapour/diesel engine as total output, vapour/diesel engine distributes downwards again, the power transmission line of vapour/diesel engine has three: one is to stir cage 3 through band transmission drive threshing cylinder 7 and spiral, stirs cage 3 by threshing cylinder 7 or spiral again and drives fan 8 with the band kind of drive; Article one, be directly to drive a dc generator by the band transmission, the electric energy that dc generator produces is supplied with front end grain lifter drive motors, horizontal grain lifter drive motors, disc cutter drive motors and vibratory sieve drive motors respectively again after control; Article three, route is to connect speed changer by transmission device, drives road wheel 11 walkings.
The utility model course of work is described: power set 12 connect speed changer by transmission device, drive road wheel 11 walkings, and operating personnel stand in this grain header rear and hold handrail along with walking gets final product.Operating personnel's effect one is to keep the fuselage balance, the 2nd, and delegation has gathered in and has turned to.Divide standing grain device 1 in the machine forefront, the straw that is gathering in that row enters between branch standing grain device two nearside dividers, enter front end grain lifter 2 again and hold up between the standing grain piece 14 along with machine moves ahead, front end grain lifter 2 is pressed deflection with straw and is drawn close from a side direction threshing cylinder 7 under the stirring of grain lifting teeth, and feeding mouth before importing, import threshing cylinder one side by guiding spiral 13 on the threshing cylinder 7 front end conical surfaces and horizontal grain lifter 15 again.Threshing cylinder 7 rotates and random device moves forward, straw fringe portion is under threshing cylinder compound motion (move ahead and rotate) effect, when moving relatively, be subjected to threshing tooth threshing on the cylinder again, the seed of taking off and short cane successively through the arc notch board 5 threshing cylinder under with after vibratory sieve 4 separates, seed stirs cage 3 through spiral and exports the mouth of putting out cereal to and collected by gathering unit.The front port from grain header under the effect of vibratory sieve and fan such as short stem and leaf grass is discharged.Straw after the threshing is moved backward along cylinder axis, discharges from the body straw outlet, cut off by disc cutter 9, lay on the ground, thereby finish the results process.
As can be seen, grain lifter is positioned at the machine left side from the figure, and straw should be positioned at the machine left side all the time when therefore gathering in.This grain header gathers in inwards from rice wheat periphery, walks counterclockwise by the rectangle route.Correspondingly, if grain lifter is positioned at the machine right side, then operation is opposite.
