The two sides of the supporting bottom plate B1 are respectively provided with a tobacco plant transverse position sensor B32, the two groups of picking mechanisms are respectively provided with four groups of tobacco plant transverse position sensors B32, the poking rods B28 of the tobacco plant transverse position sensors which are oppositely arranged are level when not poked, and the poking rods are perpendicular to the travelling direction of the gantry frame (as shown in fig. 6).
The bottom surface of the supporting bottom plate B1 of one of the two groups of picking mechanisms is provided with a sector deflector rod type trigger switch B33, the sector deflector rod type trigger switch B33 is provided with a sector deflector rod B34, and the symmetrical center line of the sector deflector rod is overlapped with the transverse center line of the split circular knife in the overlooking direction (shown in figure 7).
Specifically, the tobacco plant transverse position sensor B32 and the fan-shaped deflector rod type trigger switch B33 are two types of sensing devices for realizing the bidirectional running picking function of the picking machine, and the two types of deflector rods can be toggled bidirectionally under the action of external force and can reset automatically after the external force is withdrawn so as to adapt to the external force action from different directions of the tobacco plant during bidirectional running.
The tobacco plant transverse position sensors B32 are in a front-back bilateral symmetry layout (4 in total), the two pairs of tobacco plant transverse position sensors in the front-back symmetry layout respectively sense the tobacco plant positions in the forward running and reverse running processes, the maximum poked angle of the poking rod is in proportional relation with the transverse deviation of the tobacco plant deviated from the central line of the left and right semicircular cutters of the picking device, and the poking rod is used for sensing the transverse deviation of the tobacco plant, so that the control system of the device controls the picking mechanisms at the left and right sides to make integral translational motion, and the transverse positions of the left and right semicircular cutters are timely adjusted, so that the semicircular cutters can be transversely aligned with the tobacco plant to achieve accurate cohesion.
The fan-shaped deflector rod type trigger switch B33 can generate a trigger signal when the fan-shaped deflector rod is left and right stirred, the fan-shaped deflector rod type trigger switch is arranged under the semicircular cutter, the central line of the fan-shaped deflector rod is overlapped with the transverse central line of the semicircular cutter in the overlooking direction, when the picking mechanism is driven by the picking machine to run, tobacco plants stir the fan-shaped deflector rod, when one side of the fan-shaped deflector rod is overlapped with the central line of the semicircular cutter in the overlooking direction, a trigger signal is generated (when the tobacco plants enter the optimal cohesion area of the semicircular cutter), and the equipment control system controls the semicircular cutter holder of the picking mechanism to carry out the tobacco leaf picking action of cutting tobacco leaves from bottom to top.
The tobacco plant transverse position sensor mainly comprises a deflector rod, an angle sensor and a corner type self-resetting trigger switch, wherein a rotating shaft of the angle sensor is connected with a rotating shaft of the trigger switch through a rotating shaft connector, the deflector rod transversely passes through the rotating shaft connector and can drive the angle sensor and the rotating shaft of the trigger switch to integrally rotate under the action of external force through the rotating shaft connector, meanwhile, the deflector rod can reset by means of the self-resetting force of the rotating shaft of the trigger switch, when the tobacco leaf picking machine moves, the tobacco plant dials the deflector rod to enable the angle sensor to generate a deflection angle measured value, and the transverse offset of the tobacco plant and the center line of the semicircular cutter of the picking device is perceived by establishing a mathematical relationship between the corner and the distance of the tobacco plant from the center line of the picking device, so that the horizontal momentum of the picking mechanism is controlled, and the semicircular cutter holder is aligned with the tobacco plant; the sensing principle of the sensor is shown in fig. 8:
in the figure, D 0: the initial distance between the left swing rod and the right swing rod; l: the length of the deflector rod; d: diameter of tobacco strain S a: the distance of the actual tobacco plant deviating from the central line; s m: distance alpha of tobacco strain detected by sensor from center line: a deflector rod rotation angle;
Sm=L×（1-cosɑ）
The maximum measurement error can be represented by the following formula (1):
E=0.5×│D- D0│(1)
Therefore, when the initial distance between the left and right deflector rods of the sensor is closer to the diameter of the tobacco plant, the measurement error is smaller, and in actual operation, the initial distance between the deflector rods is adjusted according to the overall growth condition of the tobacco plant in the tobacco field.
As shown in fig. 9, a cutter holder mounting plate B35 is mounted on the upper portion of the scissor mechanism B13, two groups of cutter holder sliding rods B36 and cutter holders B37 slidably mounted on the cutter holder sliding rods are mounted on the cutter holder mounting plate, semicircular cutters B14 are mounted on the cutter holders B37, tobacco plant guide rods B38 are obliquely mounted on two sides of the cutter holders B37, two tobacco plant guide rods on the same cutter holder are in a V shape, and tobacco plant guide rods in the two groups of picking mechanisms are arranged in a staggered manner on the vertical positions of tobacco plants.
The cutter holder mounting plate B35 is provided with a reset rod B39 which is parallel to the cutter holder sliding rods, the cutter holder is in sliding connection with the reset rod, reset springs B40 are arranged on two sides of the reset rod, the semicircular cutter can slide back and forth along the two cutter holder sliding rods in the operation running direction through the cutter holder, automatic reset of the semicircular cutter is realized through the cutter holder reset springs B40, tobacco plant guide rods B38 on two sides of the semicircular cutter play a role in enabling the semicircular cutter to longitudinally and adaptively align tobacco plants through the back and forth sliding, and the action process is shown in the following figures 10 and 11.
In the schematic state shown in fig. 10, although the left and right semi-circular cutters cannot be fully aligned with the tobacco plants in the longitudinal direction, in the folding process of the semi-circular cutters, the tobacco plant guide rod B38 extrudes the tobacco plants, the reaction force of the tobacco plants to the guide rod pushes the semi-circular cutters to adaptively slide along the sliding rods in the longitudinal alignment direction, the semi-circular cutters automatically align with the tobacco plants in the longitudinal direction, and finally, the self-adaptive cohesion of the tobacco plants is completed, as shown in fig. 11, after the semi-circular cutters complete the cutting action, the semi-circular cutters release the cohesion of the tobacco plants, and the semi-circular cutters automatically return to the middle position under the action of the cutter seat return spring.
Before the picking mechanisms on two sides are folded in opposite directions, in order to enable the tobacco plants B15 to smoothly enter the folding region of the semicircular annular knife, the outer end points of the tobacco plant guide rods B38 of the semicircular annular knife cannot protrude (exceed) the outer edge surfaces of the contact blocks B31 (namely, the abutting surfaces when the two groups of picking mechanisms are relatively close) before being folded, if the outer end points of the tobacco plant guide rods B38 protrude the outer edge surfaces of the contact blocks B31, the whole semicircular annular knife seat is likely to be pushed by tobacco plants, so that the tobacco plants cannot enter the folding region of the semicircular annular knife, and finally the tobacco plants are pushed by the mechanisms or the mechanisms are damaged by the tobacco plants (as shown in fig. 12).
The lifting of the tool apron B37 is realized by changing the transverse distance between the movable hinge seat B10 and the fixed hinge seat B12 at the lower part of the fork mechanism, and because the tobacco plant guide rod B38 of the semicircular cutter cannot protrude out of the outer edge surface of the contact block B31 before the tool apron is closed, the semicircular cutters at the left side and the right side are not completely closed (as shown in figure 13) when the outer edge surfaces of the contact block B31 at the left side and the right side are just abutted, at the moment, if the fork mechanism starts to lift and cut tobacco leaves, the tobacco leaf missed cutting is caused, therefore, after the outer edge surfaces of the contact block B31 at the left side and the right side are just abutted, the fork mechanism at the left side and the right side need to be enabled to move in opposite directions, and after the semicircular cutters at the left side and the right side are fully closed, the fork mechanism can be lifted integrally to cut and pick the tobacco leaves; when the inner sliding plates at the left side and the right side continue to push in opposite directions, the shearing fork mechanism is lifted and drives the semicircular knife to cut tobacco leaves.
When the movement of the outer sliding plate B2 is not limited by external force (the outer edge surfaces of the contact blocks B31 on the left side and the right side are not propped against each other), the resistance between the sliding plate and the supporting bottom plate B1 is much smaller than the acting force of other mechanisms, and when the servo motor B4 pushes the inner sliding plate B3 to move towards the smoke post side, the inner sliding plate pushes the outer sliding plate B2 to integrally translate through the sliding rod spring B9, and no relative movement exists between the two sliding plates; when the outer sliding plate moves to a limited extent (the outer edge surfaces of the contact blocks B31 on the left side and the right side are propped against each other), the servo motor pushes the inner sliding plate to move to one side of the smoke post, the inner sliding plate and the outer sliding plate move relatively, the transverse distance between the inner sliding plate and the outer sliding plate is compressed, the thrust force required by lifting of the scissor mechanism is far greater than the friction force between the movable hinge and the sliding rod and the elastic force of the sliding rod spring, at the moment, the sliding rod spring is compressed, the scissor mechanism integrally slides on the sliding rod between the supporting seat B11 and the sliding rod fixing seat B8 through the movable hinge seat (two limit states when the scissor mechanism integrally slides on the sliding rod are shown in fig. 15 and 16), after the movable hinge seat of the scissor mechanism butts against the sliding rod fixing seat B8, at the moment, the semicircular annular cutters on the left side and the right side are integrally slid in opposite directions, so that full cohesion of the semicircular annular cutters on the smoke post is completed, and if the thrust force of the servo motor continues to act, the fork rod of the scissor mechanism is propped up (as shown in fig. 17), and the knife seat begins to cut tobacco leaves upwards.
According to the working method of the tobacco leaf picking device, in an initial state, the left picking mechanism and the right picking mechanism are symmetrically arranged on two sides of the central line of the tobacco leaf picking device, so that the semi-circular cutters on the left side and the right side are kept larger than the diameter of tobacco plants to be picked, and the tobacco plants to be picked can smoothly enter the cohesion area of the semi-circular cutters; when the machine works, the gantry type machine frame is arranged on a ridge in a crossing way, wheels at the bottoms of the two sides of the gantry type machine frame travel on a ridge passageway, and when a tobacco plant transverse position sensor senses that tobacco plants deviate from the symmetrical center line of semicircular cutters at the two sides of the picking mechanism in the traveling process, the picking mechanism at the left side and the right side integrally translate in the same direction towards the tobacco plant deviation direction under the driving of a servo motor, and the distance between the semicircular cutter seats at the left side and the right side is kept unchanged in the translation process until the cutter seats at the two sides transversely align with the tobacco plants; when the tobacco plants integrally enter the enclosing area of the left semicircular cutters and the right semicircular cutters and the sector deflector rod type trigger switch is triggered, the gantry type stand pauses running, and the picking mechanisms at the two sides are driven by the servo motor to rapidly move in opposite directions, so that the semicircular cutters at the left side and the right side are folded and the tobacco plants are enclosed; when the outer edges of the contact blocks of the outer sliding plates at the left side and the right side are propped against each other, the two outer sliding plates do not move any more, and the inner sliding plate continues to move, so that the transverse distance between the inner sliding plate and the outer sliding plate is reduced, thereby pushing the shearing fork mechanism to lift, driving the semicircular cutters to lift, and picking fresh tobacco leaves under the cohesion cutting of the left semicircular cutter and the right semicircular cutter; when the shearing fork mechanisms rise to the set highest point, the servo motors at the left side and the right side do reverse motions, the shearing fork mechanisms at the two sides start to descend and finally reversely separate under the driving of the servo motors, the shearing fork mechanisms at the two sides return to the state when the shearing fork mechanisms at the two sides just start to oppositely move and fold, and meanwhile the gantry frame is driven to integrally move forwards again to start picking tobacco leaves of the next tobacco plant.
When the motion of the outer sliding plate is not limited by external force, namely the outer sliding plates at the left side and the right side are not propped against, the servo motor pushes the inner sliding plate to move from the first end to the second end, the inner sliding plate pushes the outer sliding plate to integrally translate through the sliding rod spring, no relative motion exists between the inner sliding plate and the sliding rod spring, when the motion of the outer sliding plate is limited, namely the outer sliding plates at the left side and the right side are propped against, the servo motor pushes the inner sliding plate to continuously move from the first end to the second end, relative motion is generated between the inner sliding plate and the outer sliding plate, the transverse distance between the inner sliding plate and the outer sliding plate is compressed, and because the thrust required by lifting of the fork shearing mechanism is far greater than the friction force between the movable hinge and the sliding rod and the elastic force of the sliding rod spring, at this moment, the sliding rod spring is compressed, and after the movable hinge seat of the shearing fork mechanism butts against the sliding rod fixing seat of the sliding rod, the shearing fork mechanism is not integrally slid any more, at this moment, the semicircular cutters at the left side and the right side are correspondingly slid, so that the tobacco leaves are fully hugged up by the knife blades, if the thrust of the servo motor continues to lift the tobacco leaves upwards by the knife seat.
The tobacco leaf picking process can be decomposed into five working states as shown in fig. 18-21
1. Aligning the tobacco plants: the tobacco stems enter a tobacco stem position sensing area of the picking device, the poking rods of the tobacco stem transverse position sensor are poked, the tobacco stem position sensing sensor senses the offset distance of the tobacco stems, the servo motors on the two sides drive the scissor type picking mechanism to integrally translate in the same direction until the semicircular annular tool apron is transversely aligned with the tobacco stems, and the working state is shown in the following figure 18.
2. And (3) cohesion of tobacco plants: after the semicircular cutters are transversely aligned with the tobacco plants, the tobacco plants are stirred and trigger the sector deflector rod type trigger switch in the advancing process, at the moment, the servo motors on the two sides drive the scissor type picking mechanisms to move in opposite directions, so that the left semicircular cutter and the right semicircular cutter are fully folded and hold the tobacco plants, and the working state is shown in the following figure 19.
3. And (3) cohesion cutting: after the left semi-circular knife and the right semi-circular knife are folded, the outer edge surfaces of the contact blocks B31 on the left side and the right side are abutted against and contacted, the servo motor keeps still, the servo motor keeps the original advancing direction, the inner sliding plates on the two sides continuously move forwards to reduce the distance between the inner sliding plates and the outer sliding plates, the shearing fork mechanism is quickly lifted, the tobacco leaves are cut, after the semi-circular knife moves to the set height, the servo motor moves reversely, the shearing fork mechanism falls back, and the working state is shown in the following figure 20.
4. Resetting the tool apron: when the picking mechanism finishes picking tobacco leaves, the servo motors on the two sides drive the picking mechanism to reversely move, so that the distance between the semicircular cutters on the two sides is restored to a state just before the semicircular cutters start to fold, and the tobacco picking equipment is restarted to drive forward, so that tobacco plants can smoothly leave a picking area of the picking mechanism, when the tobacco plants leave the tobacco leaf picking area, the servo motors on the two sides drive the shearing fork mechanisms to integrally translate in the same direction, so that the center lines of the semicircular cutters on the two sides are restored to an initial position, and the working state is shown in a figure 20 below.
The innovation points of the picking mechanism are as follows:
1.
