Abstract
The utility model provides a new farmland operation implement-harrow with a tool frame mechanically moved forwards and backwards, which is provided with a front fixed harrow rod (1), a back fixed harrow rod (3), a frame (5), a support frame (9), a speed changing box (12) and a universal joint driving shaft (7). The utility model is mainly characterized in that movable harrow rods (2) and (4) are hinged by two rocker rods (11) into a four-rod mechanism which is hinged with a crank connecting rod mechanism composed of a connecting rod (10) and an eccentric wheel (14). The utility model has the advantages of reasonable structure, strong soil breaking performance and high work efficiency, the labor productivity is more than 11 times higher than that of a harrow driven by a horse, the power consumption is lower than that of a disc harrow, and the utility model can adapt to land blocks with different soil qualities and soil moisture.
Description
The utility model belongs to agricultural tool, is the facility of raking the soil level that are particularly suitable for seedbed preparation, Harrow with tool-frame mechanically moved to-and-fro.
The raking arm of prior art rake (or axle) all is to harrow body relatively to fix, and is perpendicular or parallel with direction of advance.Raking arm during work (or axle) random device together advances, will flatten with going up.Because the distance between each rake teeth (or disk) is fixed, therefore, the hack ability, the flatness on ground is also bad, can not satisfy the requirement of intensive cultivation.
The purpose of this utility model provides a kind of novel Harrow with tool-frame mechanically moved to-and-fro.Adopt the traverse motion and the complex track of deciding the linear longitudinal movement of raking arm of moving raking arm, soil is produced the strike and the cutting of both direction in length and breadth.
The purpose of this utility model reaches like this, rake is by tractor-drawn and power is provided, predetermination raking arm, back decide raking arm and framework constitutes the frame structure of harrowing, be fixed on bracket supports gearbox and the eccentric mechanism decided on the raking arm, the power of tractor inputs to gearbox by direction joint power transmission shaft.The power of gearbox exports eccentric wheel and connecting rod to, the one end hinge joint of connecting rod is on predetermination raking arm and the back moving raking arm of deciding between the raking arm, should moving raking arm by supporting (passing through bearing) after decide two rocking bars on the raking arm, be connected with another moving raking arm, the two ends of rocking bar link on two moving raking arms, two moving raking arms and two rocking bars constitute four-bar mechanism, and this four-bar mechanism is made horizontal reciprocating movement under the driving of the toggle of eccentric wheel and connecting rod composition.The rake teeth of square-section is decided to be equipped with on raking arm and the moving raking arm in predetermination raking arm, back.When tractor leads it and travels forward, the rake teeth that decide on the raking arm predetermination raking arm and back is made rectilinear motion longitudinally, rake teeth on the moving raking arm is then made horizontal reciprocating motion and the random device compound motion of lengthwise movement forward, and its movement locus is a wave (sine or a cosine curve).Like this, promptly realized the purpose that the utility model proposes.
The utility model has the advantages that simple in structurely, the arrangement of control rake teeth can realize that effect does not repeat track to soil, hack efficient height, operation quality is also higher, adapts to various on the plot of matter and soil moisture content.Boost productivity more than 10 times than the oxharrow of same structure, the power consumption than disk harrow is little again.
Description of drawings:
Accompanying drawing 1 is the vertical view toward double disking of the present utility model, and accompanying drawing 2 is left views of Fig. 1, and accompanying drawing 3 is from the forward-looking front view in back.
In the accompanying drawings, the 1. moving raking arm of predetermination raking arm 2.4., 3. raking arm is decided in the back, and 5. framework is 6. limit dark sled, 7. Cardan shaft, 8. hanger bracket, 9. support, 10. connecting rod, 11. rocking bars, 12. gearboxes, 13. struts, 14. eccentric wheels, 15. rake teeths, 16. adjusting rods.
Below in conjunction with the embodiment that provides in the accompanying drawing Harrow with tool-frame mechanically moved to-and-fro of the present utility model is elaborated.
With reference to accompanying drawing, predetermination raking arm (1), back decide raking arm (3) and framework (5) constitutes the gabarit framework of harrowing, and rake teeth (15) all is housed on it, and the interval cross arrangement of rake teeth is beneficial to hack.All parts of Harrow with tool-frame mechanically moved to-and-fro all are installed in the predetermination raking arm and decide on raking arm and the framework back.Support (9) promptly is fixed on predetermination raking arm (1) and decide on the raking arm (3) back.Gearbox (12) at the support upper support, gearbox links by the clutch end of Cardan shaft (7) with tractor.The toggle of being made up of an eccentric wheel (14) and connecting rod (10) from the power of gearbox output transmits.The other end of connecting rod and moving raking arm (2) hinge joint, moving raking arm (2) links into four-bar mechanism with (4) by two rocking bars (11), rocking bar (11) is bearing in the back by bearing to be decided on the raking arm (3), two moving raking arms are equal with the spacing of deciding raking arm (3) and the direction of motion is opposite, like this, power is easy to balance.The two ends of moving raking arm are bearing on the framework (5) by bearing holder (housing, cover), and can do in bearing holder (housing, cover) and reciprocatingly slide.Be provided with the dark adjusting device of rake at the two ends of predetermination raking arm (1), mainly contain the adjusting rod (16) of a screw-nut body and the dark sled of limit (6) of its lower end and form, adjusting rod rises, rake is dark to be increased, adjusting rod descends, and limits dark sled also to descend, and rake reduces deeply.Go up the adjusting of the degree of depth to realize rake.Whole rake body is suspended on the rear hitch of tractor by hanger bracket (8) and strut (13).Cross section toward the double disking rake teeth is a rectangle.
Its course of work is such, and when the tractor-drawn Harrow with tool-frame mechanically moved to-and-fro travelled forward, the rake teeth of deciding on the raking arm was done rectilinear motion, and the rake teeth on the moving raking arm is done the wave motion.The reciprocating power of moving raking arm comes from the clutch end of tractor, through Cardan shaft (7) to gearbox (12), export eccentric wheel (14) and the moving raking arm (2) of connecting rod (10) driving to by gearbox then, moving raking arm (2) moves raking arm (4) by two rocking bars (11) drive and does and the rightabout transverse movement of moving raking arm (2).
