Description
The utility model belongs to the whole ground group of agricultural or forestry in International Classification of Patents, also relevant with fertilising, particularly preposition hand tractor power, rearmounted rotary plow cutter shaft and the top rotary ploughing machine for covering grass of assembling longitudinal and transverse cutter sub-assembly thereof.
Returning crop stocks to the field is the effective measures that solve farmland fertilizer deficiency, but what run in production practices is season and labour's contradiction.Obviously, cut up with a hay cutter disconnected stalk earlier, turning over then is embedded under the mud, the development of such secondary operation incompatibility agricultural production.For this reason, Anqiu County Building Machinery Plant, Shandong Prov. has manufactured experimently straw chopping and returning rotovator (application number 91221861.4, notification number CN2107758U), it is once finished straw-returning and rotary tillage stubble-cleaning secondary operation are synthetic, structure from machine, need newly establish and pulverize cutter shaft, pulverize cutter, gear drive, so complex structure, heaviness, cost is higher.Be above-mentioned same purpose, Deqing, Zhejiang Province county farm machine management station develops the IGM-65A rotary ploughing machine for covering grass, it is characterized in that at the two ends of the horizontal cutter that is fixed with some pocket knives, and each fixes a vertical cutter, forms the formula sub-assembly of hurdling.18 groups of same sub-assemblies divide three sections, and 6 every section, evenly distribute, be separately fixed on four cutterheads of three sections of left, center, right of cutter shaft, the careless cutter of resistance also is housed on the cutterhead of limit.Horizontal cutter in the sub-assembly of saying and cutter shaft have one 18 ° angle.This rotary ploughing machine for covering grass has been subjected to peasant's welcome.Undeniable, it also possesses a drawback, and the phenomenon that has grass to twine axle often in operation takes place, and particularly structure is too complicated, and this is installed is the mouse cage type structure of central shaft with the cutter shaft, need remove the colter and the coulter shaft of former rotovator, the effort of taking a lot of work cost height.
The purpose of this utility model provides a kind of combined type rotary ploughing machine for covering grass.Can once finish with it and to bury grass, rotary tillage operation, overcome the disadvantage that grass twines axle simultaneously.
Scheme discloses as follows:
Engine with tractor serves as to drive power, is thereafter the chassis, and the back is a rotovator again.The rotovator colter is removed, on coulter shaft, load onto the sub-assembly of cutter in length and breadth that dissection type cutterhead and V font are arranged then.
Said dissection type cutterhead, at least one cuing open is two, is two semi circular surfaces.By the synthetic full circle of connector, coulter shaft is embraced in the cutterhead center circle.Cutterhead and tool rest are fixed.
The horizontal blade row row of longitudinal and transverse cutter sub-assembly are in the shape of the letter V, and its inboard is fixed with some pocket knives.The end points of horizontal cutter respectively is connected with a vertical cutter, and handle of a knife is fixed on cutterhead.The vertical cutter of the left and right end of coulter shaft all has a curved gesture laterally to form curved surface, and promptly total spacing of horizontal cutter is greater than left and right cutterhead spacing.In addition, one side indulge the cutter people earthwork to being shaped on cutting edge.
(when special field piece can not thoroughly solve grass and twines spool) on the hold-down support at coulter shaft two ends, installs the careless cutter of resistance separately in case of necessity.Hinder careless cutter and press close to the coulter shaft in left and right cutterhead and the cutterhead outside, and make cutting edge here meeting to direction of rotation.
According to the model machine that such scheme is made, through probationary certificate, straw-returning and rotary tillage operation can once be finished, and also can be used for rotary tillage separately.Because horizontal blade row row are in the shape of the letter V, when impetus moved on to mid point gradually by two end points, the end points of the horizontal cutter of next sub-assembly began stressed again, and is therefore stressed more even, avoided beating of machine.Because the V-shaped axial thrust load that is arranged in the farming of horizontal cutter can be cancelled out each other, reduced the load of bearing again, tractor is difficult for wandering off.Owing to adopted the dissection type cutterhead, make installing/dismounting become very convenient, topmost advantage is to have utilized former coulter shaft, needn't the new system cutter shaft, thus reduced cost significantly.Because three factors have overcome the drawback that grass twines axle: (1) vertical cutter is shaped on cutting edge; (2) vertical cutter curved gesture laterally, promptly horizontal cutter length has been blocked the exposed junction (having increased working width simultaneously) of coulter shaft greater than left and right sides cutterhead spacing; (3) V font structure has guaranteed that the grass at end points place is embedded in underground earlier.In case of necessity, set up the careless cutter of resistance after, guarantee that thoroughly solving grass twines axle.
Fig. 1 is the schematic diagram of an embodiment of the utility model.Fig. 2 is coulter shaft, cutterhead, longitudinal and transverse cutter sub-assembly and hinders assembly relation schematic diagram (sub-assembly only draws two groups) between the careless cutter, specifies as Figure of abstract.Fig. 3 is dissection type cutterhead schematic diagram (it is two that this example one is cutd open).
During enforcement, according to present technical merit, difficulty should not take place.Pre-driver engine ［ 1 ］ can adopt workers and peasants' 12 type hands (ship) to drag, and supporting with it rotovator ［ 3 ］.Remove the colter on the coulter shaft ［ 4 ］, install three the dissection type cutterheads in left, center, right ［ 10 ］ (being fixed on the nearest separately tool rest ［ 7 ］).Vertical cutter ［ 6 ］ in six groups of longitudinal and transverse cutter sub-assemblies is fixed on the cutterhead ［ 10 ］.Three groups in these six groups respectively have a vertical cutter ［ 6 ］ to insert respectively in the continuous tool rest ［ 7 ］ of left, center, right cutterhead ［ 10 ］, fixing by bolt and cutterhead ［ 10 ］.
Dissection type cutterhead ［ 10 ］ is divided into two usually, respectively welds connecting plate ［ 11 ］ on each semicircle, and the hole on the hole of its free end and the other side's semicircle is corresponding, and bolted becomes full circle.
Horizontal cutter ［ 9 ］ in the longitudinal and transverse cutter sub-assembly directly is in the shape of the letter V, and the some pocket knives of interior face down bonding ［ 8 ］ are in order to hack.Respectively connect a vertical cutter ［ 6 ］ on the two-end-point of V font, the break, the central longitudinal cutter is the plane, and left and right vertical cutter all has outside curved gesture to form curved surface.Vertical cutter ［ 6 ］ handle of a knife is all porose, and is corresponding with the hole on the cutterhead ［ 10 ］.Vertical cutter ［ 6 ］ is shaped on cutting edge in people's earthwork to this side.
In prior art, hinder the outside that careless cutter is fixed in left and right sides cutterhead, and rotate with cutter shaft.Because horizontal cutter length is not enough, it is obviously not enough to only depend on the careless cutter solution of resistance grass to twine axle.This example is respectively established a resistance careless cutter ［ 5 ］ on the hold-down support of coulter shaft ［ 4 ］ two ends, utilize the bolt on the hold-down support.This hinders the coulter shaft ［ 4 ］ that careless cutter ［ 5 ］ is pressed close to cutterhead ［ 10 ］ and cutterhead ［ 10 ］ outside, and makes cutting edge here meeting to direction of rotation.
With in, when large sized tractor is supporting, longitudinal and transverse cutter sub-assembly can be arranged in several V fonts.In addition, the break of V font can not overlap, and is
Shape.
