crossbeam two ends, can be used to install the drag that rolls that flexibly connects in case of necessity, further the finishing face of land.Hinge seat behind side connecting rod one end and the back rake group crossbeam on the left branch leg links to each other, and the hinge seat of the side that keeps left on the other end and the subsoiler frame back rest links to each other.Forward and backward rake group crossbeam, in fact the side connecting rod and the subsoiler frame back rest have formed a lanar four rod mechanism.Before rake group crossbeam rear side middle part also just be connected with one and half arc frameworks, the segmental arc of this framework is inserted in and is fixed on keep right cunning above the end of back rake group crossbeam and rolls assembly and hold and hang or push back rake group.Diagonal control arm is installed between three point linkage column triangle rear side hinge hole, upper end and the terminal journal stirrup of the straight string section of preceding rake group crossbeam half arc framework.Change for adapting to rake group diagonal control arm lower end position when the angle modulation displacement, the diagonal control arm upper end is provided with a pipe nipple, makes mutually perpendicular double-twisted structure, can transmit draw, pressure, diagonal control arm is turned round around it.For ease of adjusting or compensating error, this bar can be made into adjustable telescopic.The sail angle of biasing rake group limits by a spacer pin on fastening loop chain and the preceding left branch leg of preceding rake group crossbeam.The loop chain two ends link to each other with the ears or side handles of a utensil of back rake group crossbeam right-hand member and the clamp of three point linkage column triangle one side respectively.The adjustment that adjustable ring chain length can realize harrowing the operation drift angle.Automatically the readjustment angle function of moving of biserial biasing rake group is based on following principle and realizes: when unit was in job state, tractor was by last lower link hauling machine tool, lower link tension, upper connecting rod pressurized.At this moment, soil makes forward and backward rake group draw back into the design drift angle to the resistance of disk and the support power of diagonal control arm.Unit becomes to turn round in the edge of a field or during travel position, tractor hydraulic system promotes lower link, under the facility action of gravity, the stress of upper connecting rod and brace changes, preceding rake group is rotated to close subsoiler frame direction around right-hand member hinge point, and affect back rake group around forward and backward rake group left end hinge point near preceding rake prescription to rotation, directly go to the design end positions.The design main points of the technical program are: can realize that center of gravity moves forward to greatest extent in the time of should making facility become travel position by job state., should try one's best near preceding rake group right-hand member during the hinge point position of the preceding right supporting leg of definite preceding rake group crossbeam and the subsoiler frame back rest, this supporting leg should be tried one's best short, does not interfere with this rake group and subsoiler parts and exceeds for this reason; When determining two rake group crossbeam hinge point positions, in the time of should becoming travel position (parallel to each other) according to two rake groups, exceed with other parts mutually noninterfere, set two rake string lap K and double lines (seeing accompanying drawing 2), then, put two rakes and organize, make the setting double line I-I of two rake strings respectively in position, design maximum drift angle, II-II is got its intersection point O as this hinge point position (seeing accompanying drawing 2).
The utlity model has following advantage: because deep soil loosing shovel and biserial offset disk harrow group are combined in a machine, the soil machining functions of shovel class and disc-like operation part complements one another, thereby it is linked together wholely with rake stubble hack to the farming layer depth pine that tillage machinery proposes to have satisfied agricultural cultivating technology, realizing the requirement of multiple operation, is a kind of comparatively ideal less-tillage system type.Owing to utilize integral mode and linkage biserial biasing rake group is realized moving automatically readjustment angle function, simple and compact for structure ingenious, easy to operate, mobility is good, can satisfy the requirement of unit longitudinal stability, therefore replenish the blank of the dark pine of integral formula-biserial rake group combination type.
