Description
Technical field
What the present invention relates to is combined soil preparing machine folding frame, and particularly a kind of wide cut combined soil preparing machine folding frame with transverse copying ability, belongs to agricultural machinery technological field.
Background technology
It is one of of paramount importance cargo handling operation in agricultural production wholely.In northern China Techniques in Dry-farming Areas, the tillage operation of extensive use combined soil preparing machine before sowing in spring in agricultural production.In recent years, along with the development of agro-based industry, the speedup of big-powered tractor is very fast, in order to improve operating efficiency, reduces operating cost, effectively brings into play the advantage of big-powered tractor, and the combined soil preparing machine that working width is large has the larger market demand.Frame is the critical component of wide cut combined soil preparing machine, and all working parts are installed in frame, and its structural design is crossed performance etc. with functional reliability, operation quality and the path link of facility and is closely connected.Generally, combined soil preparing machine working width exceedes 6 meters and all adopts folding frame.At present, the version of the collapsible combined soil preparing machine frame of wide cut is: hydraulic jack control is directly installed respectively between left and right wing frame and mainframe and folds, road wheel is positioned at the middle part of frame.The shortcoming of this foldable frame is: the first, and frame length direction upper span is large, has used two oil cylinders to control respectively the folding of left and right frame, and manufacturing cost is high, and the synchronism of left and right frame is not strong when folding, folding process irregularity; The second, left and right wing frame does not possess profile modeling function, therefore easily causes working depth inconsistent.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, propose the combined soil preparing machine folding frame that a kind of low cost of manufacture, compact conformation, folding process are smooth-going, possess profiling ability everywhere.
To achieve these goals, the technical solution adopted in the present invention is: a kind of wide cut combined soil preparing machine folding frame, be made up of half hanger bracket, hoist cylinder, road wheel support arm, road wheel, left wing's frame, left lever, safety card, pole, folding oil cylinder, mainframe, right pull bar and right flank frame, left wing's frame and right flank frame are distinguished both sides hinged and mainframe; Left lever, right pull bar one end and pole are hinged, and the other end is hinged with corresponding left wing's frame, right flank frame respectively; Folding oil cylinder one end is connected on mainframe, and the other end and pole are hinged.
Above-mentioned frame, left lever is identical with right Tiebar structure, by connecting plate, Compress Spring, nut and lacing wire form, lacing wire is through on connecting plate, and Compress Spring and nut are housed in lacing wire; Left lever and right draw rod positions are with respect to folding oil cylinder symmetry.
Above-mentioned frame, half hanger bracket is connected to mainframe front, and road wheel is positioned at mainframe afterbody, and safety card is welded on mainframe top.
Compared with prior art, the invention has the beneficial effects as follows:
1, adopt a folding oil cylinder to control the folding of two wing framves in left and right, folding process is smooth-going, has reduced folding oil cylinder quantity, has reduced manufacturing cost simultaneously.
2, fold mechanism has formed the elastic adjusting device of an interlock between left wing's frame and right flank frame, and left and right frame possesses profiling ability everywhere preferably, and the working depth of workpiece is comparatively stable.
3, road wheel is arranged on to the afterbody of frame, has dwindled frame span in the longitudinal direction, be conducive to save material, overall structure is also more compact, durable.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
Shown in Fig. 1, Fig. 2 and Fig. 3, folding frame of the present invention has half hanger bracket (1), hoist cylinder (2), road wheel support arm (3), road wheel (4), left wing's frame (5), left lever (6), safety device (7), pole (8), folding oil cylinder (9), mainframe (10), right pull bar (11) and right flank frame (12) composition.Left wing's frame (4) and right flank frame (5) are articulated with respectively the both sides of mainframe (10); Left lever (6), right pull bar (11) one end and pole (8) are hinged, and the other end is hinged with corresponding left wing's frame (4), right flank frame (5) respectively; It is upper that folding oil cylinder (9) one end is connected to mainframe (10), and the other end and pole (8) are hinged.
Shown in Fig. 2, left lever in the present invention (6) is identical with the structure of right pull bar (11), and position is symmetrical with respect to folding oil cylinder (9).The fold mechanism that left lever (6), pole (8), right pull bar (11) and folding oil cylinder (9) form links together left wing's frame (5) and right flank frame (12), has formed an interlock adjusting device.In the time having right flank frame (12) to be subject to upwards active force to force it to rotate, can interlock produce to left wing's frame (5) rotation that an opposition stops right flank frame (12), thereby impel left wing's frame (5) and right flank frame (12) to keep a due level, the workpiece working depth on it is also just more consistent.Otherwise, be also like this.
Shown in Fig. 4, left lever in the present invention (6) is made up of connecting plate (6-1), Compress Spring (6-2), nut (6-3) and lacing wire (6-4), it is upper that lacing wire (6-4) is through connecting plate (6-1), and Compress Spring (6-2) and nut (6-3) are housed in lacing wire (6-4).Can regulate the compression degree of Compress Spring (6-2) by nut (6-3), thereby control the leveling capability between left wing's frame (5) and right flank frame (12).
In the present invention, half hanger bracket (1) is connected to mainframe (10) front, and road wheel (4) is positioned at mainframe (10) afterbody, and safety card (7) is welded on mainframe top.Shown in Fig. 5, on folding frame of the present invention, can be arranged in order prostatitis rake group (13), rank rear rake group (14), level land tooth plate (15), spiral hack roller (16) and ring roll (17) and form combined soil preparing machine as workpiece.Because land wheel is arranged on afterbody, each workpiece is arranged closely, and frame length can shorten 1m left and right compared with being arranged on the middle version of frame with land wheel, and therefore implement structure is more compact, durable.When work, hoist cylinder (2) shrinks, and each workpiece contacts and bear the weight of facility with ground, and road wheel (4) leaves earth's surface, under the effect of tractor drawbar pull each workpiece complete respectively loosen the soil, the flow chart such as hack, floating, suppression.When transportation, control hoist cylinder (2) and put down land wheel, make each workpiece built on stilts reach certain transportation gap.
Shown in Fig. 2, Fig. 6, when folding frame of the present invention folds, folding oil cylinder (9) extends vertically upward, promote to move on pole (8), by hinged left lever (6) and right pull bar (11), pulling force is delivered to respectively to left wing's beam (5) and right flank beam (12), under pulling force effect, left wing's beam (5) and right flank beam (12) are respectively around rotating with the pin joint of mainframe.When left wing's beam (5) and right flank beam (12) forward to behind certain position, the side bar above it just enters in the draw-in groove of installing card (7), hydraulic pressure that can the folding oil cylinder (9) of Panasonic after first-class latch (not shown) locking.
