Description

Hand tractor traction frame

The utility model relates to the hitch between hand tractor and supporting farm machinery.

Common hand tractor is in the field during (particularly paddy field) operation, all be that farm machinery directly are articulated on the traction connecting frame of tractor, operating personnel then follow in the walking of machine defensive position handle hand and operate, labour intensity is big, production efficiency also is restricted, and the seat of hand tractor normally uses when transportation.Existing seat hand tractor or harvesting and tillage machine do not possess the deflective traction function, so that the farming in plot, corner, farmland still can not solve at all.

The purpose of this utility model is that a kind of traction frame will be provided, and it not only can articulate various farm machinery but also can take operation for the driver, and can solve the farming problem in plot, corner effectively.

The purpose of this utility model is achieved in that

The traction framework is to be combined into a spatial four-bar mechanism by four rod members and two gripper shoes, the two ends of four rod members are hinged with the position, four angles of forward and backward two gripper shoes respectively, at front end towing point place, be equipped with a fanning strip that is fixed together with front end panel, fanning strip upper edge circumference has a plurality of adjustment holes, when the rod member of certain Kong Yuwei its underpart fixedly the time, the traction frame just forms certain deflective traction angle, changes the fanning strip aperture position and just can regulate the deflective traction angle.Implement hanging frame is fixed on the front side of rear bearing sheet, and the pin of the pin of a vertical direction and a horizontal direction is hinged with farm implements connecting rod and hitching frame by the cross bore frame, makes farm machinery both can do moving of horizontal direction, can swing up and down again.The upper and lower of horizontal pin is equipped with equidirectional pin-and-hole, to regulate tilling depth.Left and right two longitudinal beam front sections are horizontal, front end is fixed with the left and right angle of going up of traction framework rear bearing sheet rear side respectively, the longeron stage casing is oblique line shape, have a plurality of spacing holes on it, spacing pin can laterally be installed on certain spacing hole in longeron stage casing as the case may be, the longeron back segment is horizontal, and the seat is fixed on the top of longeron back segment, and tail wheel (using skid during paddy-field-working) is installed in the bottom of longeron back segment.A rotating shaft is by the top of bearing lateral support at left and right longitudinal beam front section, the right-hand of right vertical beam is a herringbone rocking arm control lever, the rear end of bar is a pedal, a front end and a connecting rod are hinged, have some adjustment holes on the connecting rod, the lower end of connecting rod and an adjustable plate are hinged, form a hoisting mechanism.Limit the front end of dark vertical pole to be hinged on the contact place of farm implements connecting rod and implement hanging frame by the horizontal pin on the implement hanging frame, farm implements connecting rod and the dark vertical pole of limit are at an angle, certain mid point of the two is fixed on the adjustable plate, limit the rear end of dark vertical pole to be placed on the spacing pin, play the effect of restriction tilling depth.During farm work, pedal under the driver tramps with one's feet on the seat, hoisting mechanism just can be mentioned farm machinery.Whole traction frame is connected with the hand tractor traction frame by front end panel.

Tractor driver's labour intensity when the utility model has alleviated farm work greatly, and improved production efficiency, also solved the farming problem in plot, corner.

Its concrete structure is provided by embodiment and accompanying drawing.
