Description

Soil-working implement usable either as plough or as wheel

The utility model is a kind ofly can have a product for agriculture of ploughing the soil and on the way walking two kinds of functions with the farm power machinery support uses.

It all is the form of taking by dynamic power machine traction tiller that present machinery is ploughed the soil.In order to obtain bigger tractive force, dynamic power machine generally all will have bigger deadweight, to increase the frictional force on road wheel and ground.Because engine is preceding, tillage machinery after, the result causes engine tight the soil suppression in preceding elder generation inevitably, tiller is more subsequently the unreasonable situation of native scarifying.In addition, be different situations such as adaptation nonirrigated farmland, paddy field, though but the different road wheel of engine adapted, function singleness, except that the above-mentioned suppression power that all has the soil, some wheel is as paddy field wheel, except that using on specific soil, walking neither makes things convenient for fragile again road surface on usual road surface.

The purpose of this utility model provides a kind ofly both can plough operation, again can be at the Soil-working implement usable either as plough or as wheel of road surface walking, thus overcome above-mentioned unreasonable situation, also made things convenient for use.

Structure of the present utility model is such: wheel disc of each empty cover at the two ends, the left and right sides of wheel shaft, and connect with travelling gear in the dynamic power machine transmission case by transmission mechanism respectively, be provided with some at the circumferential periphery of wheel disc and plough plough, every colter all take with the middle part of both sides respectively with about the hinged form of two wheel discs periphery.All correspondence is hinged with a rocking arm within wheel each colter pin joint on the disc radial, and the end of itself and pairing colter all forms a simple four-bar linkage by a connecting rod.To comprise that rocking arm in every group of four-bar mechanism of a slice colter and the hinge between connecting rod are as the guiding hinge, make its certain guide track motion when rotating in guiding mechanism control lower edge with wheel disc, by its drive that four-bar mechanism just can make that colter does to replace repeatedly perpendicular to ground and receive to put down and be the action of tangential direction.In order to accomplish this point, the guiding movement track of guiding hinge necessarily should be the closed curve form that and the wheel disc center of circle have radius unequal.For example can be oblate, or by the closed curve of other irregular form of some camber lines and rectilinear(-al).In order to make stretching of colter receive the flat fringe of action, this guide track is not preferably with the closed curve at turnover dead angle.When plough was in the direction of vertically stretching down, colter just can be cut in the soil following the depressing of dynamic power machine self gravitation, rotated just earth rearward to be turned over wheel and had dug, and realized ploughing operation; That colter is received is flat when being in the tangential direction of wheel disc when guiding mechanism, and just can be used as road wheel and use, smooth running, and can not damage the road surface.

Earth when ploughing in order to make on the colter in time comes off, and a cleaning shoe that can extend the colter medial surface can be set, and is fixed in the middle part of wheel shaft by support, utilizes the relative motion between the colter that rotates with wheel disc and motionless cleaning shoe that the earth in the colter is scraped.

The guiding mechanism that matches with guiding hinge in the above-mentioned four-bar mechanism can be arranged on the positioning disk that is symmetrically located at the two wheel discs outside, and positioning disk also is placed on the wheel shaft.The simplest guiding mechanism is exactly by required guide track gathering sill or guiding bulge loop to be set at the positioning disk medial surface, the hinge that respectively leads is mated and moves and realizes controlling stretching of colter and receive action along it.Because of guide track is non-circular, thus change the position of rotation angle of positioning disk and by detent mechanism fixing after, just can change the sensing that colter stretches direction, satisfy the needs of ploughing plough or walking the different work function.

The operation of rotary steering dish when ploughing plough for convenience and walking two kinds of function conversions, can be provided with conversion and control Xiao that can match on the positioning disk with the suitable mechanism on the wheel disc, when the two cooperatively interacted, positioning disk just can advancing or retreat and do forward or backwards rotation with wheel disc; After the two broke away from cooperation, positioning disk i.e. no longer rotation, just can be positioned on the dress attitude of needed position by detent mechanism.The structure that can match with conversion and control Xiao on the wheel disc can be projection, shrinkage pool, even can be the spoke that has in the wheel disc of spoke.

Describe structure of the present utility model again in detail below in conjunction with embodiment shown in the drawings.Present embodiment with hand tractor as dynamic power machine.
