Said cant beam constitutes one group by two, and two cant beam front ends distances in a group are little, and the rear end distance is big, and front end is fixed on the crossbeam with the hitch frame hinge, and the rear end is fixed on the back rest, has constituted trapezoidal frame.

Said colter is the flat board of a sheet such as right angled triangle, wedge angle forward, a right-angle side is contained in the plow standard below down, dull and stereotyped plate face is perpendicular to the ground and parallel with direct of travel.

Said tabular colter, be meant the plain line of lip-deep each the bar level of colter all with facility direction of advance line parallel, the insignificant curved surface colter in the angle and the angle of digging of not digging.

The said colter one side side tool that also is connected, side tool tabular triangular in shape, the plate face is vertical with the coulter plate face, and the limit front end that links to each other with colter is positioned at the colter lower sideline, the rear end is positioned at colter lower sideline top, and the out reach of another point of a knife is less than the lateral separation between the adjacent colter.

The lateral separation of said adjacent colter is 2-15 centimetre, many line width that the shared total fabric width of colter are not more than the stubble-cleaning crop that cant beam is installed.

Plow standard is housed before crossbeam, and the colter of installing below is a grafter shape perching knife, and its preceding forward line is parallel to the ground and be higher than the lower sideline of back colter.

Adopt the stubble cleaner of cutting apart of such scheme, can cut in the ranks too much colter at one, move ahead because colter is straight, resistance is very little, and pressure is very big, can successfully cut apart displacement to firm crop rhizome, reaches the purpose of stubble-cleaning.Simultaneously, also can be in the shared hitch frame of multiple farm implements, repacking also can become the farmland earth banking apparatus a little, and has characteristics such as simple in structure, cheap, sturdy and durable, and application prospect is very considerable.

Accompanying drawing is introduced: Fig. 1 is a kind of front view of embodiment, and Fig. 2 is its left view, and Fig. 3 is its vertical view.Fig. 4 is the front view of parts colter, and Fig. 5 is its vertical view.Fig. 6 is the front view of another parts perching knife, and Fig. 7 is its vertical view.Fig. 8, Fig. 9, Figure 10 are course of work schematic diagrames.

Among the figure as seen: hitch frame 1, crossbeam 2, cant beam 3, plow standard 4, colter 5, the back rest 6, gauge wheel 7, pull bar 8, pulling-rod frame 9, perching knife 10, leveling leading screw 11, tommy bar 12, side tool 13.

Embodiment: as shown in the figure, this stubble cleaner front portion is the hitch frame 1 that articulates usefulness with tractor, crossbeam 2 of back hinge, and crossbeam 2 back connect the cant beam 3 of two inclined in opposite directions, the plow standard 4 of 7 settings is housed on the cant beam 3 successively, a slice colter 5 respectively is housed below the plow standard 4.Colter 5 is the rectangular leg-of-mutton flat boards of a slice, and a right-angle side is following, and an acute angle directs at the dead ahead, and the plate face is upright.Under every cant beam 7 is no more than the working width of colter the line width of institute stubble-cleaning crop.Suppose that line width is 60 centimetres, the track distance of adjacent colter is advisable with 7-9 centimetre.Two cant beam rear ends are fixing by a back rest 6, the cant beam tilt adjustable.Adorn a land wheel by an adjustable for height column in the middle of the back rest, be gauge wheel 7.Erect three supports in front-axle beam 6 tops, both sides be pulling-rod frame 9, each connects a pull bar 8, the other end of pull bar 8 is pulled on the cant beam.Middle support all has relative screw with the support on the hitch frame, is linked to each other by a leveling leading screw 11, and the leading screw end is porose, and interpolation tommy bar 12 turns the horizontal level that tommy bar can be adjusted cant beam, and can cooperate pull bar 8 and gauge wheel 7 to adjust the colter embedded depth.A slice side tool 13 that also is connected in the inboard of colter, side tool is little of swallow-wing, and knife face and coulter plate face vertical side are stretched, and near lower limb, slightly upwards lift the back.In the crossbeam front, respectively there is an adjustable for height plow standard on both sides, respectively adorn a perching knife below, and knife plate protracts, and the shovel cutting edge of a knife or a sword is relative with the center line in the ranks of stubble-cleaning, and are higher than the colter lower sideline of back.During work, this stubble cleaner is articulated in the tractor back, a perching knife shovels the ground cane of stubble earlier advancing, subsequently, 7 successively cut colter, and a stubble root is divided into 7 together with Tu Fa, side tool under cut off fibrous root, and make the upturned soil sheet that displacement be arranged slightly, thereby finished the stubble-cleaning process.Because the colter knife face is straight, the knife edge is sharp keen, and cutting process advances swiftly unhindered, and resistance is very little.The stubble root is stayed in the soil after cutting, need not clear up, and both has been easy to degraded, can not influence sowing again, simultaneously, has also played the effect of loosening the soil.

Here said colter knife face is straight, be meant the plain line of lip-deep each the bar level of colter all with facility direction of advance line parallel, wherein not only comprise the plane, also comprise the very little curved surface in the angle and the angle of digging of not digging, during work, have only frictional force between colter surface and the cut surface, do not have or seldom have normal pressure.The side tool 13 of said here colter one side and the perching knife 10 of crossbeam front are not indispensable parts.
