FIG. 3 is a sectional view showing the internal structure, and a detailed explanation will be given based on this.

The first rotating case 71 is integral with a rotating cylinder 81 rotatably supported by the rear transmission frame 14 and is rotatable with respect to the rear transmission case 14, and the second rotating case 72 is rotatable with respect to the first rotating case 71. It is integral with a freely supported rotary cylinder 82 and is rotatable with respect to the first rotary case 71 . A fixed shaft 83 with one end fitted into the first rotating case 71 is provided at the rear end of the rear transmission case 14, and a sprocket 84 fixed to the rotating cylinder 81 is fitted to be rotatable around this shaft. At the same time, a gear 85 is fitted onto this shaft within the first rotating case 71. A chain 787 in the rear transmission case 14 is stretched over the sprocket 84, and the power transmitted through the chain 7 rotates the first rotating case 71 in a predetermined direction. Further, the gear 85 is meshed and connected to a gear 89 of the rotating cylinder 82 via a counter gear 88, and due to the action of these gear trains, when the first rotating case 71 rotates, the second rotating case 72
It rotates in the opposite direction at twice the speed. The first rotating case 71 is also provided with a fixed shaft 91 whose one end is fitted into the second rotating case 72. It is meshed and connected to a gear 96 of a transplant case mounting shaft 95 supported by the distal end of the case 72 and having one side protruding outside the case. Each gear ratio is set so that the transplant case mounting shaft 95 rotates relative to the second rotating case 72 but does not rotate relative to the body.

The transplant case 73 is integrally attached to the transplant case attachment shaft 95 inserted into the case.

Then, an opening/closing cam lot and an extrusion cam 102 are attached to a sleeve lOO that is fixed to the second rotating case 72 and encloses the mounting shaft 95.

5 (A) is fixed to the side surface of the transplant case 73, and the movable claw 75 (B) is attached to the lower end protrusion of the opening/closing shaft 104. Both transplant claws extend downward, and the lower end has a spatula-like shape. This serves as a clamping portion 75a. Moreover, the extruded body 7
6 is attached to the lower end protrusion of the extrusion shaft 105, and is in sliding contact with the inner surface of the fixed transplant claw 75(A).

Next, the operation of the transplant device 13 will be explained.
The rotating case 71 rotates counterclockwise in FIG. 1 at a predetermined speed corresponding to the rotational speed of the front wheels 7, 7, and the second rotating case 72 rotates twice in the opposite direction (clockwise). The transplant case 73 moves vertically in an elongated elliptical orbit. Since the transplant case attachment shaft 95 is set so as not to rotate relative to the machine body, the transplant case 73, the transplant claws 75 and 75 attached thereto, and the seedling extrusion body 76 maintain the same posture from beginning to end. P in FIG. 1 indicates the trajectory of the tip of the transplanted claw, and at point A, that is, the position of the seedling take-out port 41, the seedling pusher 76 locks onto the upper surface of the pot part of the seedling 300, and the movable claw 75 (B) When closed, the seedling located in the seedling take-out port 41 is divided into one potted seedling, which is held by a pair of transplanted claws.

The opening/closing body 42 of the seedling outlet is opened in accordance with this operation. At point B, that is, at the bottom of the trajectory, the movable claw 75
(B) opens and plants the potted seedlings in the field. Furthermore, at point 0, where the transplanted claw is a little higher than point B, the seedling pusher 76 starts to move downward, and the transplanted claw 75 (A,
Since the seedlings lifted up while still attached to B) are forcibly separated from the transplanted nails, the seedlings are reliably transplanted.

3 is formed with a cam surface 123a that operates to temporarily stop the needle-like body 115 and the plate-like body 116 at the lowest position, so that the needle-like body 115 and the plate-like body 116 sink into the soil as the body a advances. They move in a submerged state, creating transplant holes in the field. At this time, the plate-like body 116 crushes the soil that has been scraped up by the needle-like body 115, so that the soil around the transplant type is sufficiently divided into pieces. Also,
If the mulch film 303 is covered, the needle-like bodies 115 break through and tear it, thereby
A hole 303a is formed in the film. The soil pushed forward by the plate-shaped body 116 is placed around the film hole. Therefore, the edges of the film do not come into contact with the transplanted seedlings and do not interfere with the growth of the seedlings.

In the soil covering device 31, support rods 131, 131 are connected to both ends of the lower link pivot shaft 112a via universal joints 130, 130, and the support rods protrude outward and downward and then bend backward, A pair of left and right covering tools 132, 132 are supported on both sides of the ridge 305 at the rear end.

, 123, and 140 are each attached to a common cam attachment shaft 122, so the number of shafts and transmission members is small and the configuration is simple.
It is convenient to operate in synchronization with 3. Further, in this embodiment, the cam mounting shaft 122 is connected to the transplanted part mission case i.
Since this shaft is an extension of the main shaft of t, there is no need for a mechanism to drive the cam mounting shaft.

The lifting mechanism for the front and rear wheels, which are ground wheels, is hydraulic, and a hydraulic pump 15 is installed at the rear of the traveling part transmission case 3.
0 is integrally provided, and a hydraulic cylinder 152 and a hydraulic valve 153 are provided on a support stand 151 constructed between the front transmission frame lO and the side frame 20. A piston 152a of the hydraulic cylinder projects rearward, and a balance rod 156 is pivotally attached to a sliding body 155 provided at the rear end of the piston 152a so as to be rotatable in a horizontal plane. The sliding body 155 is slidable in the axial direction of the piston 152a, and is urged backward by a spring 157 fitted around the piston. In addition, the balance rod 156 has an upper plate 156a and a lower plate 156b.
and a space 16 formed in the middle thereof.
A sliding body 155 is inserted into the central part of
The sliding body 155 and the balance rod 156 are coupled to each other by being rotatably fitted therein. 163 in the figure is the sliding body 15
A stopper/pa for preventing the piston 152 from falling off is fitted onto the tip of the piston 152a. The left and right ends of the balance rod 156 are connected to the rotating cylinder portion 5 by the front wheel connecting rod 165°165.
．． It is connected to arms 166, 166 protruding from the upper surface of the rear wheel support shaft 26, and also connected to arms 168, 168 protruding from the upper surface of the rear wheel support shaft 26 by rear wheel connecting rods 167, 167.

The hydraulic cylinder 152 for driving the lifting mechanism is controlled by the following planting depth control device 170. Planting depth control device 1
70 is the rotation shaft 1 installed horizontally on the bracket 22.25.
A grounding body 173 is pivotally supported (shaft 175) on a support plate 172 protruding forward from 71, and an arm 176 integrated with the grounding body
The distal end of the hydraulic valve 153a is connected to the spool 153a of the hydraulic valve by a connecting rod 177. The grounding body 173 consists of a middle plate part 173a extending rearward from the base and side plate parts 173b and 173-b provided on both sides of the middle plate part, and has a shape that surrounds the top of the ridge 305. There is. In addition, the transplanted claw \5. 5, a notch 1 into which the needle-like body 115 and the plate-like body 116 are inserted.
73c is formed.

During the work, the middle plate part 173a slides on the upper surface of the ridge 305, and the side plate parts 173b and 173b slide on the upper slope of the ridge 305, and the work progresses while leveling the top of the ridge and adjusting according to changes in the height of the ridge. Vertical movement is by connecting rod 177
is transmitted to the spool 153a of the hydraulic valve.

That is, the grounding body 173 has the role of a ground leveling tool that levels the top of the ridge, and the role of a sensor that detects the height of the ridge. When the ridge becomes higher and the rear part of the grounding body 173 moves upward, the spool 153a is pushed in via the arm 176 and the rod 177, and the hydraulic valve 153 is switched in the direction of extending the hydraulic cylinder 152. When the hydraulic cylinder extends and the balance rod 156 moves rearward, the front wheel connecting rod 155 attached thereto,
155, arm 15 via rear wheel connecting rods 157, 157
6°156, 158, 158 are rotated, the front wheels 7°7 and the rear wheels 28.28 are simultaneously lowered, and the aircraft is lifted. Conversely, when the ridge becomes lower and the rear part of the grounding body 173 moves downward, the aircraft body is lowered. In this way, the planting depth control device 170 moves the machine up and down as appropriate in response to changes in the height of the ridges, so that the planting work is always performed under constant conditions and at a constant planting depth.

The planting depth is adjusted by adjusting the reference height of the grounding body using the planting depth adjustment lever 178.

When the lever 178 is lowered as shown by the solid line in FIG. 18, the reference height Hl is low and the planting depth is shallow. Furthermore, when the lever 178 is raised as shown by the chain line, the reference height H2 is high and the planting depth is deep.

When the planting depth is adjusted with the lever 178, the elevation angle of the grounding body 173 changes, so the sensitivity for controlling the planting depth changes.

That is, when the lever 178 is lowered to perform shallow planting, the angle of elevation of the grounding body 173 increases and the sensitivity becomes more sensitive. On the other hand, when the lever 178 is lifted to perform deep planting, the elevation angle of the grounding body 173 becomes small and the sensitivity becomes insensitive.

In addition, the valve-side hooked end 177a of the rod 177 is connected to the raised/<-t provided on the handle support frame 15.
8o is inserted into a long hole 183 of a control switching piece 182 connected by a wire 181. Raise lever 18
When 0 is the automatic control position, the end 177a is located in the center of the elongated hole 183, so the spool 153a can freely move in and out, and the elevation control is automatically performed.

When the raising lever 180 is moved to the lift position D2, the end wall surface 183a of the elongated hole pulls the rod end 177a and forcibly pushes the spool 153a, so that the body rises to the lift position.

Moreover, the space 160 of the balance rod is a space for housing the cam mechanism part of the horizontal control device 190, and the sliding body 155 has a cam receiving part 192 in which a hole 191 having an oval shape in plan view is formed.
A circular cam 19 is provided that projects laterally, and an eccentric shaft 193 is fixed to an oval hole 191 of this cam receiving part.
4 is fitted. An arm member 197 having arms 196, 196 protruding in opposite directions is fitted onto the upper part of the eccentric shaft 193 by a key 198, and the tip of the arm 196, 196 is provided with an operation button on the fixed plate 16. A wire 201 is attached that is connected to the lever 200. Note that the arm side end portion of the wire outer 202.202 is fixedly supported by an outer receiving plate 203 provided on the flat plate 156a of the balance rod 156.

To explain the attachment part of the operation lever 200, a disk 206 having a wire groove 205 formed on its outer circumferential surface is rotatably attached to the fixed plate 16 by a shaft 207, and a pivot pin 209 is attached to the disk. The base of the operating lever 200 is stuck to the cylindrical body 210 which is pivotally supported by the wire groove 20.
A wire 201 is wound around and fixed to 5. In addition,
The disk side end of the wire outer 202.202 is connected to the fixing plate 16.
It is fixedly supported by an outer receiving plate 203' fixed to the outer support plate 203'. Then, the locking plate 212 fixed to the side surface near the base of the operating unit 8-200 is connected to a plurality of locking grooves 213 formed on the vertical edge 16a of the fixing plate. It is possible to guarantee either of the following. 214 is the locking groove 213 for the operation lever 200. It is a spring that biases in the direction of...

Remove the locking 1L plate 212 from the locking groove 213 and remove the operating lever 20.
By rotating 0 in the direction of the arrow, the wire 201 wound around the disk 206 moves, and the arm member 197 rotates. Then, the cam 194 is eccentrically rotated, and the balance rod 156 is forced to swing. When the balance rod is swung counterclockwise in a plan view, the front and rear wheels on the left side move upward and the front and rear wheels on the right side move downward, so that the aircraft tilts downward to the left. Conversely, if you swing the balance rod clockwise, the aircraft will tilt downward to the right.

[Effects of the Invention] As is clear from the above explanation, the seedling stand according to the present invention has a structure in which the plan and the pot holder are arranged so that the seedlings in the last row are received and supported while receiving an appropriate resistance from the leaves. Since the distance can be adjusted according to the type of vegetables, it is possible to effectively prevent the leaves of the last row of seedlings from getting entangled with the leaves of the seedlings in the front row, allowing transplanting work to be carried out in good condition. I became able to do it.
