Description

Universal agricultural machine for field

The utility model relates to the field machinery of agricultural mechanical field.

The present field machinery that generally uses on the agricultural is all very practical when operation such as four-wheel tractor, hand tractor etc., transporting, medicine is topdressed, sprayed to arable land and seedling phase in the field.But because of the crack, ground that its vehicle frame and ground form low and non-adjustable, not only because of the wheelspan of the different above-mentioned tractors of line-spacing of Different Crop but also non-adjustable, so only be applicable to farm work before seedling phase of some crop.General when the crop plant height reach more than 500 millimeters in, the back is during vegetative period because mechanical damage is serious, present tractor has not been suitable for farm work.

The purpose of this utility model is to provide a kind of propons adjustable height, field machinery that wheelspan is adjustable.

The technical solution of the utility model is: omnipotent farm work machine, comprise chassis, dynamical system, speed change system, transmission system, steering, operating system, and on front axle assy, have propons arrangement for adjusting height and propons width adjusting device.The structure of propons arrangement for adjusting height is at the frame front end, the fixedly connected position adjustable board vertical with frame, the two rows positioning hole is arranged on the position adjustable board, be used for fixing the crossbeam cover on the propons that connects the differing heights state, crossbeam cover interpolation crossbeam post, the crossbeam post is fixedlyed connected with the column axle sleeve of the column that is used to install front-wheel, column axle sleeve interpolation column, and column can be changed according to different height needs; The propons width adjusting device is that the interpolation crossbeam post of crossbeam cover is two sections, is useful on 2～6 locating holes regulating the propons width on every section, and the hole that different locating hole on every section crossbeam post and crossbeam are put is corresponding and use locked with bolts, can regulate the propons width; For adapting to height, the width adjusting of propons, steering structure respective change, regulate for being applicable to the propons height, on steering, added the direction column, fixedly connected with direction column downside with the connecting lever that longitudinal tie flexibly connects, fixedly connected with direction column upper end with the moving arm that drag link flexibly connects, pass on the moving arm by the power of direction column twisting with connecting lever; Be applicable to the drag link TBE (threaded both ends) of propons width adjusting, cooperate, fix with locking nut behind the adjusting width with the drag link silk braid; Front-wheel cooperates the inboard, lower end or the outside that is installed in column by front axle with nut, to realize the fine setting to front tread; Whole chassis is " T " font tricycle structure rear wheel drive, connects power tool on the frame.

According to technique scheme, when in the crop place, the back is during vegetative period, propons is heightened before entering farm work, because of the chassis is " T " font tricycle structure, as long as propons can pass through, complete machine just can pass through, so, improved complete machine field through performance by regulating the propons height; The line-spacing difference of Different Crop makes this machine be suitable for the farm work of various crop by regulating the propons width; And when this machine propons is in low-end trim, also be suitable for the agricultural transportation; Because of adopting the tricycle structure single wheel to drive, reduce differential gear or turned to clutch, simple in structure, cost is low.
