Embodiment Construction
[0017] See figure 1 , figure 2 with image 3 As shown, the present invention is composed of a seedling taking clamp mechanism B and a swing mechanism C. The seedling taking clamp mechanism B is composed of a left seedling taking clamp 1, a right seedling taking clamp 2, a seedling pushing rod 3, and two rollers 4, Coupling 5, spring 6, push rod 7, two torsion springs 8, seedling clamp fixing seat 9, seedling clamp arm 10, guide block 11, push rod spring 12, shift fork 13, shift fork spring 14, cushion 15, Tighten the adjusting screw 16, the end cover 17, the cam 19, the cam pin 20 and the long crank 22. The left seedling clamp 1 and the right seedling clamp 2 are arranged oppositely, and the left and right seedling clamps 1 are in the middle The inner side of the position is hinged on the fixed seat 9 of the seedling clamp with a pin 21. The tails of the left and right seedling clamp 1 and 2 are inserted through the two ends of the coupling 5. The middle of the coupling 5 is s...

The invention discloses a planting arm of a transplanter. The planting arm of the transplanter comprises a seedling taking clamp mechanism and a swinging mechanism and is characterized in that a seedling pushing rod and a related mechanism used for pushing the seedling pushing rod are arranged between a left seedling taking clamp and a right seedling taking clamp of the seedling taking clamp mechanism, so that the clamped seedlings can be completely separated from the seedling taking clamps and the seedlings can be smoothly transplanted into the field; two rollers and a mechanism used for driving the two rollers to move are arranged between the left seedling taking clamp and the right seeding taking clamp of the seedling taking clamp mechanism, so that the seedling taking clamps can stretch smoothly, and the seedlings are transplanted into the field; the seedling taking clamp mechanism is provided with two torsion springs, the inner ends of the two torsion springs are hinged by a pin shaft, and the outer ends of the two torsion springs are respectively buckled at the outer sides of the left seedling taking clamp and the right seedling taking clamp, so that the left seedling taking clamp and the right seedling taking clamp are clamped inwards, a clamping resultant force of the seedling taking clamps is increased, the seedlings can be clamped, and phenomenon that the seedlings fall off does not exist; and a cushion pad is arranged below a shifting fork of the seedling taking mechanism, and the swinging mechanism is optimized in design, so that vibration and the noise of the planting arm disclosed by the invention are greatly reduced.
Description
Technical field [0001] The invention relates to a rice transplanter, in particular to a planting arm of the transplanter. Background technique [0002] At present, the structure of the transplanting arm of the existing transplanter is that there is no seedling pushing mechanism between the left and right seedling picking clamps, and the seedlings are planted only by the expansion of the seedling picking clamps. As a result, sometimes the clamped seedlings cannot be completely connected with each other. The seedling holder is separated, and the seedling cannot be transplanted into the field; in addition, the design of the opening and closing mechanism of the seedling holder of the transplanting arm of the existing transplanting machine is unreasonable, resulting in unsmooth opening and insufficient clamping force of the seedling holder , Sometimes the seedlings cannot be clamped; in addition, the planting arms of the existing transplanting machines vibrate and make louder noises. ...
