Further specify embodiment of the present utility model below in conjunction with accompanying drawing
Description of drawings Fig. 1 be a kind of self-propelled not in lines schematic diagram Fig. 2 of long-stalked crops silage fodder grain header be among Fig. 1 not in lines ceding of Taiwan schematic diagram Fig. 3 be that feeding unit structural representation Fig. 4 A is that shredding mechanism cylindrical shell among Fig. 1, notch board schematic diagram Fig. 4 B are shredding mechanism hobboing cutter schematic diagrames among Fig. 1 among Fig. 1
Fig. 1,2,3,4A, 4B, 5 and Fig. 6 in, the utility model provides a kind of self-propelled not long-stalked crops silage fodder grain header in lines, mainly by nearside divider 1, hold up standing grain carry tooth 2, disc cutter 3, revolving drum 4, middle conveying roller 5, preceding go up feeding roller 6, the preceding roller 7 of feeding down, in down feeding roller 8, back go up feeding roller 9, back down feeding roller 10, shredding mechanism 11, throw blowing fan 12, throw send tins 13, start motor-driven 14, chassis frame 15, road wheel 16, throwing send guide plate 17, transmission jackshaft 18, driver's cabin 19 to form.In Fig. 2, this not in lines the ceding of Taiwan 100 by nearside divider 1, hold up standing grain to carry tooth 2, disc cutter 3, revolving drum 4, middle conveying roller 5 and little nearside divider 24 to form.In Fig. 3 this feeding unit 200 by feeding roller 6 on preceding, preceding down feeding roller 7, in feed roller 10, connecting lever 20 or 22, spring 21 or 22 down on feeding roller 8, the back under feeding roller 9, the back and form.In Fig. 4 A, 4B, shredding mechanism 300 is made up of shredder bar cylindrical shell 25, stationary knife 26, notch board 27, knife sharpening device 28, knife section 29.
The driver's cabin 19 of this long-stalked crops silage fodder grain header is positioned at not the ceding of Taiwan 100 back in lines, the top of shredding mechanism 300, not in lines the ceding of Taiwan 300 in the machine front, feeding unit 200 is below driver's cabin 19, the front of shredding mechanism 300, throwing are sent device to be included as throwing and are sent tube 13 and quicken fan 12, and throwing send 13 lower end and shredding mechanism 300 to join, throwing send tube 13 upper ends to be flat camber line shape, and outlet is above the machine afterbody.Engine 14 is positioned at the machine back.
The ceding of Taiwan 100 in lines is not positioned at the machine dead ahead, be connected fast with feeding unit 200, and hydraulic lifting, fast convenient.Middle conveying roller 5 is that the crop after the cutting is transported to 200,5 conveying rollers of feeding unit between the ceding of Taiwan 100 and feeding unit 200.
Feeding unit 200 is positioned at driver's cabin 19 belows, between middle conveying roller 5 and shredding mechanism 11, plays evenly feeding.Last feeding roller 6,9 can float, and purpose is to adapt to different feed quantities and play compaction.Feeding roller two ends are fixed with side frame respectively, above two go up feeding rollers 6,9 and can fluctuate, be pressed on down by spring 21,22 and feed on the roller.
Shredding mechanism 300 is fixed on the crossbeam of frame both sides, is the material chopping that feeding unit 200 is sent here.This shredding mechanism 200 is main working parts of silage fodder grain header, and the quality of cutting quality depends primarily on this device.Shredding mechanism 300 rotating speeds are higher, reach 1100 rev/mins, so this device will carry out dynamic balancing, in order to avoid produce judder, influence the service life of cutting quality and parts.Material after throwing send tube 13 and acceleration fan 12 with shredding mechanism 300 choppings, throwing is delivered in the car that connects material, throwing send tube 13 to be made up of upper and lower two joints and acceleration fan 12, doffing one end and chopping cylinder are joined, the other end is connected with the acceleration fan, and the top cylinder bottom links to each other with the acceleration fan, and the top cylinder exit has to throw send guide plate, quicken fan be contained in doffing above, make to throw and send the crop in the tube to throw fast in the car that connects material.
In Fig. 5, drive line divides two-way for the power that is come by engine 14 output, and one the tunnel passes to running gear 16 through transmission jackshaft 18; Shredding mechanism 300 is passed to through transmission jackshaft 18 in another road, is passed to by shredding mechanism 300 and quickens fan 13 and workpieces such as the feeding unit 200 and the ceding of Taiwan 100.
Following brief introduction technological process and the quick of each parts are connected.
The main technique flow process is as follows: nearside divider 1 separately crop → disc cutter 3 cutting crop → little nearside dividers carries crop → middle conveying roller → feeding unit → shredding mechanism → throwing to send that device → car connects material with the common clamping of seven circle moving teeth.
In Fig. 6, feeding unit hangs up by bottom rotating shaft and shredding mechanism, and top is blocked with U type card and got final product.The ceding of Taiwan articulates by top swash plate and feeding unit, and the bottom is blocked with connecting plate and feeding unit projecting shaft and got final product.
The main feature of this utility model machine: complete machine structure is simple, compact, and scientific allocation is reasonable, Position of centre of gravity is suitable, and it is reliable and stable to walk. Because main working parts reasonable in design, parameter are earlier Advance, make this machine operation performance and operation quality all better. This machine adopts the disk revolution ceding of Taiwan, adapts to not Raise the long-stalked crops results with the green grass or young crops of line-spacing, can satisfy the requirement of domestic different regions harvesting silage crop. This machine production efficiency height, gather in the crops high stalk silage crop per hour reach 9-14 mu/hour, the height for the stubble left is low In 110mm, the harvesting loss rate is less than 3%. The driveline arrangement of the utility model machine is reasonable, transmission Circuit is simple, reliable, has effectively utilized engine power, has satisfied green grass or young crops and has raised the operation of machine efficient reaping Requirement.
