Abstract
The utility model relates to an unpowered crop harvesting implement. Moved and fixed blades are installed on a moved and a fixed blade holders respectively, wherein, the fixed blade holder is united with a machine frame which is provided with land wheels and handles; the land wheels are connected with the machine frame through a drive mechanism which is connected with a power frame through a crank link mechanism. The utility model has the advantages of simple structure, less components, reliable motion, large rotating torque, operating labor saving, high work efficiency, and suitable for old and weak manpower.
Description
The utility model relates to a kind of crop cropper tool, specifically a kind of unpowered harvesting utensil.
CN2045571U discloses a kind of hand push grain header, and its primary structure is to be made of bevel gear wheel, bevel pinion, power transmission shaft, bent axle, connecting rod, last lower slide and blade, slide block, slide bar, little support wheel etc.This device drives the transmission of a series of parts such as bent axle, connecting rod, slide block, slide bar, knife rest by big bevel pinion transmission, and the final relative motion that realizes going up bottom knife reaches the purpose of shearing crop straw.Because its drive disk assembly is more, make structure comparatively complicated, coefficient of reliability reduces, and the processing of parts such as big bevel pinion also difficulty is bigger, make cost improve.
The purpose of this utility model just provides the novel shear grain header that a kind of drive disk assembly is few, reliable in action is laborsaving, simple in structure, realizes the harvesting to rice wheat and other cereal.
The utility model is achieved in that ledger-plate is contained in the front end of frame, and knife section is installed on the movable knife rack, and land wheel joins by axle and frame, and handle is connected to the rear end of frame.Have transmission mechanism to join between land wheel and frame, toggle connects transmission mechanism and movable knife rack.By people's pushing handle, land wheel is rotated, frame is advanced, and land wheel is reciprocating by transmission mechanism drive toggle simultaneously, makes the relative frame of movable knife rack make the shearing motion that relative motion realizes running and fixed blade.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model when upright;
Fig. 3 is the carriage cutaway view between frame and the knife section.
As shown in Figure 1, 2, the front end of frame 8 is ledger-plates 10, and movable knife rack 7 is at frame front, and knife section 9 is equipped with in the top.Running and fixed blade can adopt the form of the running and fixed blade on the supporting little wheat harvester of existing and small tractor.Be that each knife section is triangular in shape, the compact part sword rib that protrudes cutting edge is arranged on the two most advanced and sophisticated declivous cutting edges, a plurality of blades are fixedly installed on the movable knife rack side by side.Ledger-plate is sharp lance shape, and there is groove at the middle part, for inserting knife section, the sword rib of compact part is arranged also on its cutting edge, so that blade when relative shear, can hold together straw, does not make slippage.By axle 17 fixedly connected land wheels 1, this land wheel is as driving wheel at frame rear end.There are handle 12 and frame to join at axle 17 two ends, and by nut 11 tightenings.Between frame 8 and land wheel 1, also have transmission mechanism to join.Transmission mechanism constitutes for tooth uniform on land wheel one side perimeters and the drive 2 that is engaged with, and drive 2 is fixed on the frame 8 by axle 3 and support 5.Drive 2 can be gear structure, also can be the squirrel-cage wheel construction.On support 5, also bearing can be installed, be enclosed within the two ends of axle 3, with the resistance of further reducing friction.Go back socket toggle 4 on one end of the axle 3 in the transmission mechanism.This toggle is taken turns with the eccentric connecting rod that is connected with it by one and is constituted, and the steady pin 6 on another termination movable knife rack 7 of connecting rod is with the linear reciprocating motion of realization movable knife rack.For reducing the frictional force of relative motion between movable knife rack 7 and the frame 8, between its contact-making surface, be provided with carriage, make sliding friction become rolling friction, its structure is as shown in Figure 3.This carriage is by sliding members 13, and groove 15 on connecting axle 14, the knife section and the groove on the frame 16 constitute.Sliding members 13 is bearing or ball.Can near four corners, respectively install one under the whole knife section, constitute stable support, on frame 8, also can connect a crank guard rail 19, cross, make the crop straw of cutting off slide to grain header one side along this guardrail from the movable knife rack top of frame.In addition, can directly make a translot on the frame, make to cooperate and insert knife section and movable knife rack with groove on the ledger-plate, also the frame relevant position can be made the step plane, movable knife rack is placed on down on the plane, rank, fixes two pressing plates 20 on plane, last rank, the effect of grooving, but simplify the structure.For making whole grain header stable working, land wheel 1 can adopt the two-wheel structure, also two-wheeled can be connected spoke by deciding bar 18 simultaneously, and constitute the double linked wheel form.Working stability has more increased rotating torque on the other hand on the one hand, makes work more reliable.On the wheel edge of land wheel, can make several protruding pillars nails, prevent to skid.
The utility model adopts between land wheel and frame has transmission mechanism directly to join, and toggle directly connects transmission mechanism and movable knife rack, makes that structure is the simplest, and parts are few, reliable in action.Carriage between big and movable knife rack and frame of rotating torque makes the harvesting operation laborsaving efficient in addition.Cut 1 hour 1 mu of ground of wheat through field test, thrust needs only 7 kilograms, and the weak labour of woman all can use.
