Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its embodiment of rice transplanting machine with several rows of rotary rice seedling claws, structure, feature and the effect thereof that foundation the present invention proposes, describe in detail as after.
See also Fig. 1, shown in Figure 2, Fig. 1, Fig. 2 are the movable seedling jaws of rice transplanting machine with several rows of rotary rice seedling claws of the present invention.
Movable seedling jaw is for the action of anthropomorphic dummy's finger when the rice transplanting.Finger is when rice transplanting, mainly be that a hand-held seedling cooperates, the thumb of another hand and forefinger, middle finger are commanded by human brain according to the arm motion position, finish the opening and closing of the intermittent reciprocating clocklike campaign of putting seedling after seedling taking clamps, divides, inserts in certain spatial dimension; Therefore can do the opening and closing campaign on the movable seedling jaw structure is a key condition; Another condition is that assurance activity seedling jaw gets, inserts, puts seedling at branch, returns to the branch seedling taking, inserts, puts and do in the seedling loop cycle clocklike that intermittent reciprocating opens or closing motion.Specifically be contemplated that: at first movable seedling jaw is made of two seedling jaws, and a seedling jaw is equivalent to people's thumb, and another seedling jaw is equivalent to people's middle finger and forefinger, movable seedling jaw of the common composition of such two seedling jaws.The structure of movable seedling jaw adopts---" scissor " hinge structure, and toggle replaces the posterior joint of finger, and seedling jaw replaces the preceding joint of finger, and both adopt detachable being fixedly hinged.As long as " scissor " hinge structure holding rod relatively rotates, just can realize opening or closing motion of seedling jaw like this; Simultaneously movable in order to realize on single a plurality of movable seedling jaw structure, the seedling pawl tier pole of connection activity seedling jaw can be formed by axially movable seedling pawl tier pole by two, movement locus because of " scissor " hinge structure holding rod is the circular arc of radii fixus again, in order to eliminate the influence that it moves the axial straight line of two seedling pawl tier poles, movable seedling jaw two toggles should adopt the hinge formula to connect respectively with two seedling pawl tier poles, and 2 hinged points keep suitable distance; When the corresponding axial straight line of two seedling pawl tier poles work moved, two seedling jaws just can reach corresponding closure or opening movement like this.And its intermittent reciprocating motion clocklike when the rice transplanting operation of movable seedling jaw---open or closing motion, because of seedling jaw for finishing the rice transplanting operation, the movement locus line that certain rule is all arranged in the space of rice transplanter, need only requirement like this according to seedling jaw rice transplanting operation, be equipped with corresponding fragment size and its variation changeover portion for two seedling pawl tier pole two ends, just can instruct to it, thereby be that realization activity seedling jaw clocklike intermittently opens or closing motion has been created condition.In order to simplify movable seedling jaw structure, through research repeatedly, the closing motion of determining movable seedling jaw relies on two seedling pawl tier pole two ends to move and realize in the changeover portion compression that segmentation changes of fixedly installing of the axial dimension of its running orbit space of lines; And its opening movement---the simplest method is to rely on the cooperation of the energy of stage clip storage and the axial dimension segmentation variation that its seedling pawl tier pole two ends are provided with in its running orbit to realize jointly.
Can be divided into anterior seedling taking open section, rear portion clamping seedling open section on the upper and lower seedling jaw structure in the movable in addition seedling jaw, pre-small post-large on the size, can suitably strengthen the stroke that the seedling jaw seedling taking clamps in the axial stroke of seedling pawl tier pole, the movable seedling jaw like this, can suitably reduce simultaneously because of the influence of making, assembly precision is realized motion, and movable seedling jaw also has an action of separating seedlings or planting when clamping seedling downwards.
As shown in Figure 1, effective working width L=NT of movable seedling jaw, wherein N is the seedling jaw space-number, T is the cave spacing in the every row of determining according to agriculture requirement of rice shoot.Adopting end seedling hinge bar shown in Figure 1 at the two ends of movable seedling jaw, is for the length that guarantees seedling pawl sliding bar and effective working width basically identical of movable seedling jaw.The structure of the traversing minor axis assembly 9 among Fig. 1, the cover 10 that rolls is a kind of version that designs for rice transplanting machine with several rows of rotary rice seedling claws, if desired, can do corresponding choice or adjust to change.Because of the relation of physical dimension, for reach each upper and lower seedling jaw treat seedling taking, opening and variable quantity is relative consistent when clamping, inserting the seedling section, the position of hinge I with upper and lower straight seedling bar that left and right end seedling hinge bar connects in the position should be different to some extent.Design is during stage clip, and its minimum working thrust sum should be greater than putting seedling resistance and frictional resistance sum about 1.5 times.Upper and lower seedling jaw application 65Mn steel wire is made, and enough rigidity and length will be arranged, and the seedling toggle does not bury when guaranteeing work, reduces working resistance to reduce sectional area, and also making rice shoot insert the back all has more soil to shield and sustain rice shoot all around.
With reference to the structure of Fig. 1, when movable seedling jaw moves in certain space, its space motion path line is divided into and treats seedling taking section, clamp segment, put the seedling section and each transition linkage section is formed, and give every section corresponding size and the variation changeover portion is connected.Like this when movable seedling jaw shown in Figure 1 moves to corresponding changeover portion, just at stage clip 12 and traversing minor axis assembly 9, major axis 11, split pin or nut 13, connect under the effect of minor axis 15, make seedling pawl row slip cross bar 7 begin to move at three changeover portions---be the corresponding segment distance that moves, can make so the left and right end seedling hinge bar affixed with seedling pawl row slip cross bar, up and down the straight also corresponding mobile phase of seedling toggle with distance, by the effect of hinge I, hinge II, make down seedling jaw 1, last seedling jaw 2 reach intermittent reciprocating motion clocklike; And in three sections because of the axial dimension no change, therefore movable seedling jaw does not move.So necessary motion when having reached its anthropomorphic dummy and pointing rice transplanting.
See also Fig. 3, shown in Figure 4, Fig. 3 is revolution driver, the structure of expansion bend and the structural design schematic diagram of both coupling methods, and Fig. 4 is the end view of Fig. 3.Among the figure, lower contact 17, the short crank 18 of expansion bend, the long crank I 19 of expansion bend, the long crank II 20 of expansion bend, guide post 21, stage clip 22, center hinge 23, and all the other respectively cut with scissors 24 composition expansion bends.Among the figure ← → expression stretching motion direction.
As seen from Figure 3, when the fraising in 20 two vacancies of long crank II with expansion bend by hinge respectively with movable seedling jaw in connect on the two seedling pawl slip cross bars relevant hinged after, by the planar degrees of freedom theory as can be known: the planar degrees of freedom of expansion bend is 1.Movable seedling jaw is made stretching motion only.And the coupling method in the employing diagram after expansion bend and the connection of revolution driver, just can be arranged several expansion bends (physical dimension that needs only part allows) in the revolution driver of small radii.
See also Fig. 5, shown in Figure 6, Fig. 5 is the structural representation of track plate of the present invention.Fig. 6 is the comparison schematic diagram of different phase among Fig. 5.Among the figure, the groove depth angle of climb of every section changeover portion should be not more than 20 degree; Should be the sudden change value and put the seedling initial point after inserting to the groove depth variation of putting the seedling section, only need to get final product with less round-corner transition according to the manufacturing process of this part.
As shown in Figure 6, be clamp segment 26, treat seedling taking section 28 and put the comparison schematic diagram of seedling section 32, among the figure, t1 be in the movable seedling jaw traversing minor axis by the axial stroke amount for the treatment of that seedling taking clamps after the seedling taking; T2 be in the movable seedling jaw traversing minor axis by clamping seedling to the axial stroke amount of putting the seedling section; T3 be in the movable seedling jaw traversing minor axis by putting the seedling section to the axial stroke amount for the treatment of the seedling taking section.
See also shown in Figure 7ly, Fig. 7 is the kinematic sketch of the motion of movable seedling jaw turning anticlockwise and stretching motion thereof, intermittent reciprocating motion clocklike.Among the figure, D1 is its diameter; II, III are middle transmission row number; The radius of the revolution basic circle at the movable seedling jaw of R2 top; α is that movable seedling jaw connects counterclockwise drift angle with expansion bend; H1, h2, α 1, α 2, α 3, with each symbolic significance among track plate structural representation Fig. 3; * with ⊙ represent respectively seedling pawl row slip cross bar can vertical paper inwards and outside move toward one another direction.
As shown in Figure 7, the motion principle of movable seedling jaw turning anticlockwise, flexible and regular intermittent reciprocating motion is: when the chain crop rotation rotates counterclockwise, the revolution driver coaxial with it also together rotates counterclockwise, effect because of relations such as relevant structure among Fig. 1, Fig. 3 and Fig. 5 and combinations thereof, so just, under the restriction of track plate dish groove two side and bottom land, also do flexible and intermittent reciprocating motion clocklike when making movable seedling jaw do the turning anticlockwise motion, and make above-mentioned three motor coordinations as one man by predetermined combination requirement operation by pre-provisioning request.
See also shown in Figure 8ly, Fig. 8 is the kinematic sketch of the highly automated adjustment movement at random of movable seedling jaw and ground leveling motion.
Mechanism as shown in Figure 8 can be reduced to the crank four-bar linkages such as plane of modification, because of the member that waits connecting rod in the crank four-bar linkage that constitutes modification more, so do following some processing at first technically: the one, formation activity seedling jaw turning anticlockwise is moved, stretching motion, the corresponding driving member and the seedling basket support (comprising movable seedling basket) of all parts of regular intermittent reciprocating motion and the motion of part acquisition activity seedling pawl turning anticlockwise, height conditioning signal assembly and connection part pass through the both sides track plate on the structure, rotary middle spindle and supporting member thereof, organic whole of compositions such as seedling basket support and securing member---and make the connecting rod of crank four-bar linkages such as modification; The 2nd, connect with the crank in the crank four-bar linkage that waits of modification by the both sides trapped orbit dish in the above organic whole, and the radius value of its crank should keep equating in theory with the centre-to-centre spacing value of the kind of drive that makes the rotating rotary main shaft motion of movable seedling jaw; The 3rd, for rigidity and the stability that strengthens organic whole, should adopt the crank of each identical one group of third-class throw of crankshaft of bikini with the crank four-bar linkage that waits that both sides trapped orbit dish connects; The 4th, with the highly automated signal component of regulating at random of movable seedling jaw, link up by highly automated relevant of regulating at random and securing member and both sides track plate, and with signal element---roller assembly stretches out suitable distance value and keeps in touch with ground, paddy field.
According to " rational mechanics ", relevant principles such as " tractor theories ", known motion of mechanism principle as shown in Figure 8: because of ground, paddy field relation because of farming before rice transplanting, generally the relative variation of numerical value is less within the specific limits for the bearing capacity of its shallow topsoil, and effective contact area on height conditioning signal element 43 and ground is when its sagging depth value has small variation, its effective contact area changes then bigger relatively, to offer the variation of bearing reaction of signal element then bigger on ground like this, relation because of power and equalising torque, just can realize that the member among Fig. 8 reaches the translation of the organic whole of the organic whole of forming with the seedling basket support 41, and also automated randomized rising of the height of movable seedling jaw wherein or decline, crank 40 rotates simultaneously, because of sprocket wheel, relevant of rotary main shaft 37 and its pairing transmission maintains fixing centre-to-centre spacing.Reached the highly automated adjustment movement at random of movable seedling jaw like this, made movable seedling jaw turning anticlockwise, flexible, regular intermittent reciprocating move also unaffected simultaneously.
In addition, because when complete machine moves, because of signal element and ground be remain contact and certain sagging degree of depth arranged, so because drag effect of surface soil, signal element just can be around its fixedly gyroaxis do rolling clockwise, promote and suppress the earth in its place ahead, so just also realized leveling campaign ground.
Can get a kind of moving method with reference to Fig. 8,, adopt the mode of mechanical suspension or hydraulic suspension and power set or power unit to be complementary complete machine, can realize that just complete machine moves as long as by machine frame at two sides.
See also Fig. 9, shown in Figure 10, Fig. 9 is that effective working width is the front view in 1 meter the general assembly drawing of the movable seedling jaw rice transplanter of swinging six rows, and Figure 10 is the B-B profile of Fig. 9.
As Fig. 9, shown in Figure 10, the rice transplanting machine with several rows of rotary rice seedling claws that the present invention proposes, it comprises frame, left and right sides track plate, main shaft, movable seedling jaw, revolution driver and expansion bend etc., wherein on the track plate of the left and right sides main shaft is installed, the central authorities of this main shaft are equipped with the single-revolution driver, the two ends of main shaft are equipped with a left side, right track plate, expansion bend links together with the revolution driver, movable seedling jaw is connected with the revolution driver, and movable seedling jaw is for having intermittent reciprocating clocklike, revolution, flexible, highly automated structure of regulating bilayer three hinges four bars of four motions at random.
As the design philosophy of rice transplanting machine with several rows of rotary rice seedling claws of the present invention, at first be in rice transplanter, to arrange the movable seedling jaws of many rows, obviously can be in the speed of travel that improves rice transplanter the speed of effective reduction activity seedling jaw.Therefore, for reaching this purpose, the movement locus of movable seedling jaw need be helicoid closed orbit trace after deliberation.
1, the setting of complete machine main motion number
In rice transplanting machine with several rows of rotary rice seedling claws,, realize the purpose of design for finishing the task of rice transplanting operation.Complete machine main motion number is set to: the moving of complete machine; Flexible and intermittent reciprocating motion clocklike when the turning anticlockwise of movable seedling jaw and revolution thereof; The automatic adjustment movement of height random of movable seedling jaw; Seedling sending campaign and reduction are to moving that whole ground flatness requires wholely; Amount to seven main motion numbers.Wherein: four compound motions of movable seedling jaw are nucleus movement.
2, the design of seven main motions of complete machine
Soft because of paddy field soil, adhesive force is little, slippage rate is bigger.When the paddy-field-working, it trackslips or skids the influence of rice transplanter motion and service behaviour for fear of power set or power unit.So recommend the motion of power set or power unit and the motion of rice transplanter are separated---be that rice transplanter is finished above seven motions under tractions such as power set or power unit.
(1), the design of movable seedling jaw turning anticlockwise motion
At first the direction of advance that moves with complete machine is the operative orientation of rice transplanter rice transplanting operation.Rice transplanter adapts to the present situation of different terrain paddy field ridge in order to make, clear area, elimination complete machine unnecessary when reducing rice transplanting moves the influence of rice transplanting seedling, and movable seedling jaw rotates counterclockwise, and movable seedling jaw is from the rice transplanting of complete machine rear portion during work.
The design of movable seedling jaw turning anticlockwise motion is specifically:
Adopt trapped orbit disc cams pattern exactly, movable seedling jaw is equivalent to roller and does the turning anticlockwise motion around fixing gyroaxis in the dish groove; Because of the relation of movable seedling jaw structure and the realization of intermittent reciprocating motion clocklike thereof, the left and right sides track plate that needs to adopt two and be oppositely disposed in both sides connects movable seedling jaw assembly and gyroaxis relative fixed with relevant part simultaneously.And its rotate counterclockwise direction according to the moved end, source turn to the middle kind of drive and " Machine Design " in transmission principle just can realize.
The design of stretching motion when (2), the movable seedling jaw turning anticlockwise of many rows moves
Because of the major function of movable seedling jaw in complete machine is to fix a point to get branch automatically, clamp, insert, put seedling.In order to satisfy the requirement of this major function, movable seedling jaw also need satisfy because of the variation of getting branch, clamp, insert, put seedling, its turning radius in this periodic duty process of seedling taking is treated in recovery when doing the turning anticlockwise motion---and be that movable seedling jaw need be made stretching motion.And rice transplanter when work, the stretching motion amount of general activity seedling jaw is all bigger, in order to remedy the variation of its turning radius, guarantee that its gyration successfully presses desired trajectory line operation, make simultaneously its stretching motion flexibly, effectively, reliable, resistance is little etc., through ferment repeatedly, demonstration etc., the mode of the stretching motion of the movable seedling jaws of many rows is contemplated that:
Two waists of two groups of diagonal of two isosceles trapezoids in the plane of modification and an isosceles trapezoid reach and add a hinged point in one group of isosceles trapezoid two diagonal therein, and are equivalent to plane nine rod-type expansion bends with adding common formation such as a guide rod and movable seedling jaw, lower contact after the hinge pin modification.Its lower contact is a dead lever, be used to connect two waist toggle and location guides, one group of diagonal toggle one end of hinged point is connected with two waist toggles in the middle of having, the other end is connected with other one group of diagonal toggle one end, and two slip cross bars in an other end of other one group of diagonal toggle and the movable seedling jaw adopt suitable form hinged.Because of the expansion bend that connects movable seedling jaw assembly is a plane, so can arrange several on a surface of revolution, so movable seedling jaw assembly also can be arranged several.
(3), movable seedling jaw is done the design of the regular intermittent reciprocating motion in turning anticlockwise, the stretching motion
Because of the structure of preceding described movable seedling jaw and the design of turning anticlockwise motion and stretching motion, for the seedling jaw that guarantees movable seedling jaw is put seedling after clamping, inserting, is returned to and treat to do in this loop cycle course of work of seedling taking state intermittent reciprocating motion clocklike again after seedling taking, and can with movable seedling jaw revolution and the harmonious effectively motion of stretching motion.Be contemplated that:
The groove depth of trapped orbit dish is divided into corresponding three sections degree of depth and connects the changeover portion variation.When movable seedling jaw moves to every section changeover portion, just can make seedling jaw do clocklike to move back and forth like this, then can be motionless in the time of every section.(note: after inserting, put seedling for the seedling jaw that guarantees movable seedling jaw and the axial top of traversing minor axis assembly and treat not contact with the track plate bottom land the seedling taking state procedure to recovering with ground, reduce the resistance of motion, can adopt the groove depth variable quantity of suitable increasing track plate after putting seedling, and put seedling section stroke as far as possible, simultaneously in movable seedling jaw, utilize relevant part to control the stroke of traversing minor axis assembly, its axial top do not contacted with bottom land---be preset clearance.)
