Therefore, the problem that the clamping stagnation phenomenon of the existing machine type causes damage to the seedling clamping mechanism and affects seedling production operation is solved.
Working principle: step one: the switch of the lithium battery power system 17 is turned on, the power supply is turned on, the gear shifting handles of the left and right gearbox assemblies 16 are placed at a rapid position, and the electric seedling transplanting machine is rapidly walked to an operation site through the operation control system 22.
Step two: before starting to work, the self-propelled seedling transplanting machine is aligned with the seedling bed to be planted at a proper position of the ground, and the gear shifting handles of the left and right gearbox assemblies 16 are placed at a slow speed position.
Step three: the hydraulic power unit 21 is connected through the operation control system 22, so that the suspension device 23 drives the working device main body 24 to descend to a proper working position (the ditching depth is determined according to the size of the seedlings).
Step four: the left seedling box 26, the right seedling box 26, the front seedling box 28 and the rear seedling box 28 are fully filled with seedlings to be planted, operators start to deliver seedlings to the seedling clamping mechanism 36 at various positions, then the gear shifting handles of the left gearbox assembly 16 and the right gearbox assembly 16 are placed at a slow speed, the unit is made to walk slowly through the operation control system 22, meanwhile, the operation device is started to drive the gear reduction motor 25 to drive the gear reduction mechanism 32 to drive the chain wheel 34-5 to rotate, and the chain connecting mechanism 34 is driven to drive the furrow opener 37 and the seedling clamping mechanism 36 to enable the operation device to start operation.
Step five: during operation, the furrow opener 37 has the main functions of furrowing, earthing and compacting, and drives the seedling clamping mechanism 36 to clamp, throw and remove seedlings. When the furrow opener 37 moves between the chain wheel 34-1 and the chain wheel 34-2, the two rollers 37-1 on the furrow opener advance between the upper flat rail 31 and the lower flat rail 33, so that the furrow opener 37 is in a horizontal moving state, and the seedling clamping mechanism 36 is opened upwards along with the furrow opener, so that seedlings can be delivered by operators conveniently.
Step six: when the furrow opener 37 moves between the chain wheel 34-2 and the chain wheel 34-3, the two rollers 37-1 on the furrow opener are not limited by the track, so that the furrow opener 36 is in a vertically downward moving state under the action of dead weight, and the seedling clamping mechanism 36 for clamping seedlings moves along the same direction, so that preparation is made for the next step of ditching and seedling throwing.
Step seven: when the furrow opener 37 moves between the chain wheel 34-3 and the chain wheel 34-4, the two rollers 37-1 on the furrow opener run between the upper inclined track 35 and the lower inclined track 38, and the furrow opener 37 is forced to perform a furrow opening and soil raking operation; at the same time, the straight-bar seedling clamping device 36 clamping the seedlings brings the seedlings into the ditches. The ditching and soil raking process is also a soil covering process in practice, and the part of the soil moved in the ditching process just buries the seedlings in the previous ditches.
Step eight: when the furrow opener 37 moves between the chain wheel 34-4 and the chain wheel 34-5, the two rollers 37-1 on the furrow opener run between the horizontal sections of the upper inclined track 35 and the lower inclined track 38, and the furrow opener 37 is forced to perform the furrowing, soil raking and compacting operations; at this point, the seedling clamping mechanism 36, which clamps the seedlings, has then brought the seedlings to the appropriate transplanting location.
Step nine: when the furrow opener 37 moves between the chain wheel 34-5 and the chain wheel 34-1, the two rollers 37-1 on the furrow opener are separated from the constraint of the horizontal sections of the upper inclined rail 35 and the lower inclined rail 38, the furrow opener 37 starts to move upwards freely, and the working processes of furrowing, earthing and compacting are completed; at this time, the seedling clamping mechanism 36 still needs to stay in the groove of the lower inclined rail 38 for a period of time, and waits for the next furrow opener 37 to finish the soil covering and compacting operation on the seedlings carried by the furrow opener.
Step ten: the next furrow opener 37 pushes the seedlings carried by the seedling clamping mechanism 36 out of the grooves of the lower inclined rail 38 after the soil covering and compacting operation are completed; at this time, the seedling clamping mechanism 36 returns to the original position under the combined action of its own spring and the anti-jamming mechanism 39.
Step eleven: when the furrow opener 37 pushes the seedling clamping mechanism 36 out of the groove of the lower inclined track 38, the gear 39-5 coaxial with the chain wheel 34-5 drives the transition gear 39-1 and the gear 39-4 to rotate, drives the upper deflector rod 39-3, dials the lower deflector rod 39-2, and the shifting fork linked with the upper deflector rod dials the seedling clamping mechanism 36 for a certain distance and then returns to each other.
Step twelve: when the shank 37 moves to the position of sprocket 34-1, it is returned to the process of step five by the flipping mechanism 41. The operation is repeated in this way, so that the seedling bed changing transplanting operation is continuously completed.
