The second gear case 21 at this time is connected to the first planetary gear 14 so that the first gear case 11 rotates in a direction opposite to the first gear case 11.

The second gear case 21 rotates at a speed twice as fast as that of the first gear case 11 while being opposite in the direction of rotation to the first gear case 11 like the first planetary gear 14. [

In the second gear case 21, the second idle gear 23 rotates in the same rotational direction as the second gear case 21 about the second sun gear 22 accommodated in the second gear case 21, And the second planetary gear 24, which is gear-coupled with the gear 23, is rotated in the opposite direction.

The second sun gear 22 and the second idler gear 23 and the second planetary gear 24 have the same rotation ratio as the first planetary gear 14 and the second sun gear 22, 2: 1, so that the second planetary gear 24 rotates half a turn while the second gear case 21 rotates one wheel.

That is, the second planetary gear 24 rotates at the same angle in the opposite direction to the first gear case 11.

Therefore, the second gear case 21 makes two revolutions while the first gear case 11 rotates once, and the second gear case 21 rotates in the opposite direction to the second gear case 21, 2 planetary gear 24 is rotated one rotation in the same rotational direction as the first gear case 11.

On the other hand, the first idle gear 13 and the first planetary gear 14, the second idle gear 23, and the second planetary gear 24 are rotated finely so that the same gears are stacked so as to overlap each other The first idle gear 13 and the second idle gear 23 are prevented from backlashing with the first planetary gear 14 and the second planetary gear 24 by providing the anti-backlash preventing gears 16 and 17, So that power transmission can be performed.

The second planetary gear 24 is connected to the hopper operating portion 30 for opening and closing the hopper 35 by rotation of the second planetary gear 24, The slider guide 31 is fixedly engaged with the gear boss 241 of the second planetary gear 24 so as to be rotated simultaneously with the second planetary gear 24. [

The second planetary gear 24 is rotated in the opposite direction at a speed 1/2 of the rotational speed of the second gear case 21 so that the slider guide 31 fixed to the second planetary gear 24 is always perpendicular The state of FIG.

In the present invention, the first gear case 11 and the second gear case 21 are provided with the same number of rotations in the positions of the sun gears 12 and 22 and the planetary gears 14 and 24, A sprocket or a timing gear is provided so that the sprocket and the timing gear are connected to each other as a chain or a timing belt so that the same operation can be realized.

In other words, the fixed shafts 120, 140, 220 and 240, which have supported the sun gears 12 and 22 and the planetary gears 14 and 24 in the gear cases 11 and 21, One sprocket or a timing gear is fixedly supported on the fixed shaft 120 of the first gear case 11 while the timing gear is axially coupled and another sprocket or timing gear is supported on the corresponding fixed shaft 140 by a bearing As shown in Fig.

Also, one sprocket or timing gear is fixedly supported on the fixed shaft 220 of the second gear case 21, and another sprocket or timing gear is rotatably supported on the fixed shaft 240 by the bearing So that the shaft is supported.

The sprocket or timing gear of the first gear case 11 on the sun gear 12 side and the sprocket or the timing gear on the side of the planetary gear 14 are 1: 22) side sprocket or the timing gear and the planetary gear 24 side sprocket or the timing gear is 2: 1.

FIGS. 11 to 14 sequentially illustrate the operating states of the hopper driving apparatus for a grabber according to the present invention.

As illustrated, when the implanted device moves, the first gear case 11 moves in the moving direction and the first gear case 11 rotates in the moving direction of the moving device about the driving shaft 15.

When the first driving unit 10 and the second driving unit 20 rotate in opposite directions as the grafting machine moves, the hopper operating unit 30 axially coupled to the second driving unit 20 always keeps the hopper 35 in a vertical state While moving in the vertical direction.

In other words, when the first driving unit 10 is rotated in a state where the implanted device is stopped, the hopper operating unit 30 ascends and descends in an oval-shaped moving locus so that the middle of the hopper operating unit 30 is spaced apart by a predetermined width. 1 drive unit 10 is rotated, the hopper operating unit 30 shows an operating structure in which the section in which the hopper 35 is inserted into the ground is moved up and down on the same vertical line.

10, when the first driving unit 10 is rotated in the clockwise direction by the movement of the implanted device, the second driving units 20 rotating in the counterclockwise direction are rotated in the same direction in opposite directions to each other, The hopper operating part 30 fixed to the second planetary gear 24 in the driving part 20 moves the hopper 35 downward while maintaining the vertical state by the rotation of the second planetary gear 24. [

The turning radius of the first gear case 11 in the first driving portion 10 is formed larger than the turning radius of the second gear case 21 of the second driving portion 20, As the radius becomes larger, the distance to the same vertical line between the hoppers 35 provided in the hopper operating portion 30 becomes longer, while the distance on the same horizontal line becomes as narrow as possible.

The hopper operating portion 30 that is rotated so as to rotate simultaneously with the second planetary gear 24 rotating opposite to the rotational direction of the second gear case 21 is rotated by the rotation of the second planetary gear 24 to rotate the hopper 35 ) Is always kept in a vertical state while an elliptical movement locus is formed in the vertical direction.

The hopper 35 is accommodated in the interior of the hopper 35 in a closed state, and the hopper 35 descends on the same vertical line of the paper 40 by the movement of the grafting machine.

The hopper 35 in the hopper operating portion 30 coupled to the second gear case 21 at the same time as the first gear case 11 moves moves vertically in a state in which the lower portion between the separated both side surfaces is closed While the lower end thereof is brought into contact with the paper surface (40).

11, the hopper 35 is rotated by a second planetary gear 24, which is supported by the hopper operating portion 30, when the lower portion of the separated side faces is vertically lowered to a predetermined depth in a closed state The drive shaft 15 is positioned on the same vertical line.

When the slider 32 of the hopper operating portion 30 is forcibly pushed down by the cam 33 after the closed lower end of the hopper 35 is inserted up to a certain depth in the ground, The lower part of both sides of the hopper 35 is rotated in mutually corresponding directions while the hopper operation space 34 is rotated so that the closed lower part is opened.

The slider 32 is gradually lowered at the portion where the outer diameter of the cam 33 is changed so that the rotation angle of the hopper operation space 34 is increased so that the opening area at the lower portion of the hopper 35 is increased So that the seedlings accommodated in the hopper 35 drop downward.

The lower portion of the hopper 35 is opened from a certain depth of the ground to a predetermined height, but the opened state is maintained until it is released from the paper surface 40 as shown in FIG. 13, and the opened lower portion is closed again.

After the hopper 35 is inserted into the ground at a predetermined depth and then the bottom is opened, the hopper 35 is continuously moved until the bottom is closed by elevating the hopper 35 from the ground 40 by a predetermined height, So that the seedlings can be implanted at uniform intervals at all times while ascending and descending on the same vertical line.

In the seedling transplanting, the hopper 35 is provided on both sides or one side of the first driving part 10, so that the seedlings can be transplanted at regular intervals in cooperation with the movement of the transplanting machine, So that it can be formed more densely.

Particularly, in the present invention, the hopper 35 can be always maintained in a vertical state by the rotation of the second planetary gear 24, and the seedling implantation due to the opening / The second planetary gear 24 is rotated by the rotation of the second planetary gear 24, which eliminates the need for a separate configuration for the operation of the hopper as before.

The opening and closing operation of the hopper 35 is manually performed while the hopper 35 is inserted at a predetermined depth into the ground. The hopper 35 is released from the ground 40 in an open state, Operability and seedling transplantation are made possible.
