Description
The utility model belongs to agriculture scarification equipment offset mounting rake series.
Offset hangs the supporting middle-size and small-size used with tractor of rake in agriculture tillage operation, as ploughing back hack, stubble-cleaning, occupies certain status in the disk harrow series of products.Existing model structure generally is rigidity rake frame upper offset and arranges forward and backward two row rake groups, and the adjustment of rake group job angle realizes by the bolt apertures position of changing between rake group crossbeam and the rake frame.Be subjected to tractor to hang the restriction of ability and unit longitudinal stability index, the single-chip microcomputer of this type of rake is heavy less, and the rake width of cloth is narrower, and complete machine weight is lighter, is difficult to adapt to the agriculture requirement of doing farmwork for a soldier's family with rake in the agricultural tillage transformation of the way.
The purpose of this utility model provide a kind of automatically significantly transposition move heavy offset and hang rake, the automatic realization of facility center of gravity is moved forward to greatest extent and improve longitudinal stability, angle modulation is convenient during job state.Compare with general biasing rake, during identical fabric width, single-chip microcomputer is heavy can be strengthened; The single-chip microcomputer heavy phase at that time, working width can increase, thereby can improve operation effectiveness or operating efficiency.
Basic design of the present utility model comprises three point linkage, preceding rake group, back rake group, side connecting rod ASSY, diagonal control arm assembly, counterweight assembly and angle modulation chain assembly.Following suspension plate, the column triangular symmetry of three point linkage are arranged on its front-axle beam, and the lateral attitude can be regulated.Front-axle beam right-hand member (facing the direction setting that advances, down together) is provided with the hinge seat of the preceding rake group of a connection, and the left side is provided with another hinge seat that is used for connecting the side connecting rod, the cursor slide of rake group before the back, left side is rigidly connected and is used for carrying.Right supporting leg before the rake group crossbeam of preceding rake group is established links with front-axle beam right-hand member hinge seat; Be provided with above the left side to slide and roll assembly, can be inserted in the cursor slide on the front-axle beam; The left end back is provided with left back supporting leg; The back, middle part just has been connected with long half an arc framework, and the straight string section of framework end is welded with journal stirrup; Rake string before install the below, the blade concave surface is towards the right side.The rake group crossbeam left end of back rake group has preceding left branch leg, be provided with preceding rake group crossbeam after the hinge hole of left branch leg hinge joint be used for being connected the hinge seat of lateral bracing strut with another; Be provided with the sliding assembly that rolls above the right side and can be inserted in the length half arc framework segmental arc that back, preceding rake group crossbeam middle part has just connected; The end of keeping right is provided with the semi-ring ears or side handles of a utensil that are used for connecting the angle modulation loop chain; Back rake string is installed in the below, and the blade concave surface left; Connecting hole or Connection Block are made in these rake group 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 keep left hinge seat of side of the other end and three point linkage front-axle beam links to each other.In fact forward and backward rake group crossbeam, side connecting rod and three point linkage front-axle beam formed a mobility is 1 four-bar linkage.The diagonal control arm assembly is installed between three point linkage column triangle rear side hinge hole, upper end and the terminal journal stirrup of the preceding rake group crossbeam straight string section of long half arc framework.Change for adapting to rake group diagonal control arm lower end position when the transposition angle modulation, the diagonal control arm upper end is provided with a pipe nipple, makes mutually perpendicular double-twisted structure, can transmit pressure, and diagonal control arm is turned round around it.For ease of adjusting and compensating error, this bar can be made into adjustable telescopic.The operation drift angle of biasing rake group is limited and is adjusted by the fastening loop chain.The loop chain two ends link to each other with the semi-ring ears or side handles of a utensil of back rake group crossbeam right-hand member and the clamp of column triangle one side respectively.Balancing weight, axle and extensible link (being made up of sliding pin, sliding pole axis, sliding sleeve axle) etc. constitute the counterweight assembly, and balancing weight is chained together by axle, and device is on the slide rail of the straight section of long half arc framework.Axle is provided with the hinge point near the end of back rake group crossbeam, and links to each other by the hinge seat at middle part on extensible link and the back rake group crossbeam, and balancing weight rake group crossbeam subsequently moves together.This novel automatically significantly transposition move heavy function and be based on following principle and realize: when unit was in job state, front and back rake group is drawn back was limiting operation under the drift angle, this moment balancing weight be positioned at before and after rake group middle part slightly near the position of back rake group; 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 front-axle beam 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.Simultaneously, balancing weight under the affecting of back rake group crossbeam, is forward harrowed prescription to slip along slide rail by extensible link, and until end positions, this moment, balancing weight was positioned at front-axle beam and preceding rake group crossbeam centre position.The design main points of the technical program are: realize that center of gravity moves forward to greatest extent when making facility become travel position by job state, when determining forward and backward rake group hinge point position, in the time of should becoming travel position (parallel to each other) according to two rake groups, exceed with the parts mutually noninterfere, set two rake string transposition lap K and transposition double lines, putting two rakes then organizes in position, design maximum drift angle, make setting double line I---I and II---II of two rake strings respectively, get its intersection point 0 as this hinge point position (seeing accompanying drawing 2).
The utlity model has following advantage: utilize integral mode and linkage, rake group lateral adjustments, balancing weight center of gravity realize automatically that to biserial biasing rake group significantly transposition moves readjustment angle function with the facility state variation etc. relatively but adopt hitch point simultaneously.Simple and compact for structure ingenious, easy to operate, mobility is good.Compare with general biasing rake, when the facility working width was identical, single-chip microcomputer is heavy can be strengthened, and operation effectiveness is good, can satisfy with the rake agriculture requirement of doing farmwork for a soldier's family; Facility single-chip microcomputer heavy phase at that time, working width can increase, operating efficiency improves.
