Description
The utility model belongs to the grain header technical field, relates to a kind of reaping hook formula harvester header.
Harvester for both rice and wheat can alleviate the labour intensity of peasants' harvester for rice wheat greatly, at northern area owing to mostly be the flat area, help of the harvesting of large-scale combine to wheat, and at vast southern area, owing to be the mountain area, hills mostly, the paddy field is more, therefore, large-scale combine can't carry out operation, makes the harvesting machineryization of rice, be difficult to realize always, though had many agricultural mechanical technology personnel developing the Rice harvester that is fit to southern area in recent years, the ceding of Taiwan of these grain headers mostly volume is big, complex structure, heavy, power consumption is big, inconvenient operation, the suffered resistance of cutter is big, is easy to wearing and tearing, cause the harvesting efficiency of complete machine low, therefore all be difficult to promote the use of.
The purpose of this utility model be to provide a kind of simple in structure, volume is little, in light weight, the cutter resistance is little, harvesting efficiency is high, the reaping hook formula harvester header of easy operating.
The purpose of this utility model realizes with the following methods, this reaping hook formula harvester header comprises the harvesting frame, nearside divider, grain lifter, dial voltage regulator, knife section, on the harvesting frame, movable knife rack is arranged, movable knife rack by be positioned at harvesting on the frame two gear wheels and the hinge of two runners, be linked to be integral body with the harvesting frame, and make movable knife rack and two gear wheels, two runners form quadric chain, gear wheel and the pinion of importing power, knife section is a simulation reaping hook structure, be fixed on the front end of power rack, the ledger-plate that is fixed on the harvesting frame is being arranged on the knife section, nearside divider is to be hinged by two connecting rods, the linkage that other two ends are hinged respectively and form on harvesting frame and movable knife rack, grain lifter and group voltage regulator are fixed on the movable knife rack.Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail.
Fig. 1 is front view of the present utility model (having removed as the view behind the ledger-plate of cover plate);
Fig. 2 is the A-A cutaway view (having loaded onto ledger-plate) of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1;
Fig. 4 is that J among Fig. 2 is to view;
Fig. 5 is that K among Fig. 2 is to view.
Among the figure:

The harvesting frame (1) that two connecting rods of nearside divider (19) is connected in respectively goes up with movable knife rack (2) and forms bar linkage structure, the reciprocating separately straw of adhesion that plays a part.Grain lifter (18) is to be fixed on harvesting frame (1) to go up with knife section (17) and make synchronous circular motion, the crops straw of need cutting is embraced buttress past ledger-plate (22) and cut.The reaping hook structure of using when knife section (17) is the simulation hand harvest, knife section (17) is fixed on makes circular motion and the shearing force that synthesizes as the ledger-plate (22) of cover plate and grain header walking inertia force crops on the movable knife rack (2), finish the shearing to crop.Dial voltage regulator (23) and be fixed on the movable knife rack (2) of header, make circular motion, with the uniform lay of crops and be sent to conveyer belt with movable knife rack (2).The motion process of movable knife rack (2) is to be driven by the output shaft of diesel engine to be delivered to pinion (8) by bevel gear (12), pinion (8) drives gear wheel (6,7) rotate, gear wheel is fixed on the harvesting frame (1), movable knife rack (2) has two fulcrums to be fixed on the radius of gear wheel, movable knife rack two fulcrums in addition is fixed on runner (3,4) on, runner (3,4) be fixed on again on the harvesting frame (1), gear wheel (6,7) rotation makes movable knife rack make circular motion (being equivalent to lanar four rod mechanism), knife section on the movable knife rack (17) is made circular motion equally on the bar-shaped trough (24) of harvesting frame (1), realize cutting to the rice bar with ledger-plate (22).
The ceding of Taiwan of the utility model and existing grain header relatively has following characteristics:
1, simple in structure, the accuracy of manufacture of each parts requires constant, and with more in light weight about 20% with the grain header of productivity ratio, volume is little about 25%, and center of gravity is lower.
2, successfully simulate the action of artificial harvester for rice wheat crops.The branch standing grain of header, hold up standing grain, the harvesting program of cutting, falling all is the artificial harvesting action of simulation, and is little to the damage of crops like this, the net harvesting rate height, good stability holds susceptible to user acceptance.
3, the power of Xiao Haoing is little.Knife section (17) has adopted reaping hook formula structure, and adopt the camber line cutting in when cutting, relatively to have a cutting resistance little and durable in use with existing shearing harvester header, and reaping hook can autogenous grinding in the harvesting process, use sharper and sharper, when reaping hook wear and tear can not the time spent.Be easy to change.The cutting force of ledger-plate (22) is consistent with the direction of advance of grain header in addition, so a part of inertia force changes cutting force into, has so just reduced required cutting force widely.
4, applicability is strong, because nearside divider (19) the structure uniqueness of design, the action that simulation manually divides standing grain with rod separates thoroughly between standing grain and the standing grain.Grain lifter (18) can be propped up the crops of the attitude that lodges arbitrarily, take in one's arms and be sent to cutter cutting in addition, so this novel header can gather in the crops that the lodging degree is a zero degree, and the rice and wheat of the various planting patternss of suitable straight harvesting (program request, disseminate irregular slotting kind) is made class.In addition, the utility model be design in the front of grain header, volume is little, in light weight, center of gravity is low, the harvesting of going to the field the time need not manually be cleared the way, be suitable for the various irregular fields of harvesting, also be applicable to the field that area is little, because in light weight, difficult sinking, so also adapt to the dark rice field of harvesting mud pin.
