The invention relates to a movable tipping harrow, comprising a harrow teeth element, an adjustable brake, a dragging tripod, rotating-connecting leaves, and a harrow tooth tipping element formed by a middle spindle and a movable connecting cover located on the middle spindle. The movable terminals of the two rotating-connecting leaves are connected respectively with the two terminals on the bottom of the dragging tripod, and the fixed terminals of the rotating-connecting leaves are fixed onto the two terminals of the middle spindle respectively. The movable terminal of the movable connecting cover is connected with a hollow teeth bar on the hollow teeth element, wherein the fixed terminal of the movable connecting cover is fixed on the middle spindle. An adjustable crank of the adjustable brake is arranged on the middle of the middle spindle, wherein adjustable gears are fixed on the bottom edge of the dragging tripod. The movable connecting cover is a closing-page typed connecting cover formed by two end-to-end joint typed covers. Between the adjustable brake and the cover head, a locating bar, a propping up spring and a rotating fulcrum form a locating system. The utility model has the advantages in simple structure, easy operation, safe application and reliability. The hollow teeth element can rotate 180 degree by circling the middle spindle.

Description

Convertible movable creeper

Technical field:

The utility model relates to the farm implements in the whole field of a kind of farming rake, relates in particular to a kind of movable creeper.

Background technology:

The agricultural machinery that is used to harrow whole field easily of extensive use in the present rural area, general all is that the creeper that has a plurality of rake teeths is directly hung on hand tractor or other power traction machines, used creeper has single shaft and twin shaft two kinds: the rake teeth of single shaft is directly fixing with the welding of traction tripod, the rake teeth angle can not change, the rake teeth bar of twin shaft flexibly connects with the traction tripod, the adjusting rim brake is installed on it, when rake is put in order the field, can according to circumstances adjusts the angle on rake teeth and ground by a small margin.These two kinds of creepers are in off working state, when caring for the creeper walking with hand tractor or other power traction machines, rake teeth is always towards the back lower place, even the adjustable creeper of twin shaft also can't be adjusted to rake teeth safe position, therefore as easy as rolling off a log legs and feet of hindering the people are particularly more dangerous when crossing ridge.

The utility model content:

The purpose of this utility model is: provide a kind of convertible movable creeper of safe in utilization, more reasonable structure, to solve do not work unsafe problems when being cared for the band rake and travel by the power hauling machine of existing creeper.

In order to reach above purpose, the technical scheme that the utility model is taked is: a kind of convertible movable creeper, comprise the rake teeth assembly, regulate rim brake, the traction tripod, the strand that is rotationally connected page or leaf, it is characterized in that: this convertible movable creeper also has by jackshaft, be positioned at the rake teeth turning device that the flexible connection cover on the jackshaft is formed, the movable end of the strand that is rotationally connected page or leaf is fixedly linked with the two ends, base of drawing tripod respectively, the stiff end of the strand that is rotationally connected page or leaf is installed in the two ends of jackshaft respectively, the movable end and the rake teeth assembly that flexibly connect cover are fixedly linked, the stiff end that flexibly connects cover is fixed on the jackshaft, the regulating handle of regulating rim brake is positioned on the middle part of jackshaft, and adjusting gear is fixed on the base of traction tripod.

Described flexible connection cover is the hinge-type adapter sleeve that two pairs of dock kinks constitute, the dock kink is respectively by two pairs of block sets and pullover the composition, one end symmetry of described block set has two quadrangle grooves, overlapping first end is smooth cross section, the other end has the quadrangle plush copper of two symmetries, pullover plush copper shape is similar to the block set groove shapes, the phase interfix is moved tight fit, two block sets are enclosed within the two ends of jackshaft in the same way and are welded on the jackshaft, the two pullover jackshafts that are enclosed within are in the same way fixedlyed connected near the homonymy of corresponding block set and with the rake teeth bar of rake teeth assembly, and pullover and block set are at 0 °, the tight fit butt joint of two positions of 180 ° of degree.

Another feature of the present utility model is: regulate rim brake and kink pullover between by the stop bit device of forming by stop bit push rod, jack-up spring, rotating fulcrum, stop bit push rod one end is that flat lever-like handle, the other end are the stop bit push rod head, fixedly connected with the rotating fulcrum on being fixed on jackshaft in stop bit push rod middle part, side near handle is equipped with the jack-up spring, and the stop bit push rod head of opposite side is withstood the pullover rear end that is in the state of plugging together with block set.

The convertible movable creeper of the utility model has the following advantages owing to taked above technical scheme:

One, need band rake transport condition again at not cultivated rake, rake teeth can be turned to home---be about to 180 ° of rake teeth upsets, always be turned to the front upper place---, to guarantee the not legs and feet of harm people towards the hauling machine direction towards the back lower place by original;

Two, simple in structure, easy to operate;

Three, the characteristics that kept the adjustable creeper of original twin shaft can suitably be adjusted rake teeth to certain angle according to the actual conditions of the scope of operation, simplify use.

Be described further below in conjunction with the technical characterictic of drawings and Examples the convertible movable creeper of the utility model:
