DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a field effect transplanter for transplanting seedlings on the upper surface of a ridge, in which the machine body can be easily turned at the end of the ridge.

[0002]

2. Description of the Related Art In a conventional field effect transplanter, a pair of drive wheels are provided on the left and right sides of the fuselage. The fuselage is propelled so that these drive wheels straddle a ridge, and a transplant rod is provided on the upper surface of the ridge. Transplant the seedlings on the seedling platform. In this way, when the aircraft comes to the end of the ridge, the aircraft is operated to turn (U-turn) and turn back. Here, mainly two types of methods are used. In other words, there are a method in which the transplanting rod transplants the seedling to the center of the ridge, and a method in which the transplanting rod transplants the seedling to the right or left of the center of the ridge. Then, in the former, when the body comes to the end of the ridge, it turns so as to move the body to the next ridge.
Further, in the latter case, during the movement of the body to a new ridge similar to the former, the body is turned around the center of the pair of drive wheels, and reciprocates on the same ridge. That is, the seedlings are transplanted, for example, on the right side of the center of the ridge on the outward path, and are transplanted on the left side, which is the opposite side when viewed from the same direction, on the return path, and two rows are planted for one ridge.

[0003]

In the former of the prior art, the rotation of the driving wheel on the center side of the turning is stopped at the end of the ridge, and the body is turned by the rotation of the outer driving wheel. Then, the driving wheel, which is the center of turning, is between the ridge where the seedlings have been planted and the ridge that is to be planted next (valley), and the outer driving vehicle has the ridges that have been planted and the ridges that are to be planted. Move over the two. For this reason, there is a possibility that the machine body is largely tilted twice in the left-right direction to disturb the seedlings on the seedling mounting table.

[0004] In the latter case, when the body turns at the end of the ridge, the left and right drive wheels simultaneously rise from the valley to the upper surface of the ridge and then descend the valley at the same time. The seedling table on the seedling table may be disturbed, or the drive wheels may collapse on the upper surface of the ridge. The present invention aims to prevent the seedlings on the seedling mounting table from being disturbed and the upper surface of the ridges from being roughened by wheels by smoothly turning the body at the ends of the ridges.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a case where a right and left wheel 10 straddling a ridge A and a side view of a vehicle body.
A wheel provided at a position separated from the left and right wheels 10 in the front-rear direction.
And 24 in the field effect transplanter provided independently.
When the wheel 18 is lowered below the other wheels 10 and 24,
At the vicinity of the contact position of the left and right wheels 10 in the side view of the fuselage.
A field action transplanter is provided with a wheel lowering device 19 for lowering the ground .

[0006]

Since the present invention is constructed as described above, the left and right wheels 10 and the front of the left and right wheels 10 during the seedling planting operation.
Along the ridge A by wheels 24 provided at a position separated in the rearward direction
The airframe 6 is run to perform seedling planting work. Then, when trying to turn at the end of the ridge A, the wheel lowering device 1
9 independently lowers one wheel 18. Then, this one wheel 18 descends to the field scene and the wheel 18
Supports the body 6 with the other wheels 10 and 24 provided on the body 6
Float. At this time, this one wheel 18 is viewed from the side of the fuselage.
So that it touches the ground near the grounding position of the left and right wheels 10
As it descends to the scene, the operator
The fuselage 6 can be easily supported by one wheel 18 .
Therefore, the operator can easily turn the fuselage 6 around the turning wheel 18 by 180 ° or transfer the fuselage 6 to the adjacent ridge A as if turning a single cat wheel. Further, collapse of the ridge A due to the left and right inclination of the body 6 and the wheels 10, 18, and 24 provided on the body 6 is reduced, and the transplanting operation can be performed smoothly.

[0007]

Next, an embodiment of the present invention will be described. FIG.
As described above, the engine 1, the main gear box 2, the pipe frame 3, the rear gear box 4, and the bevel gear box 5 are connected in order from the front to form the body 6. As shown in FIG.
Rotating cylinders 8, 8 are attached so as to cover them, and transmission cases 9, 9 are inclined downward from the outer ends of the respective rotating cylinders 8, 8. Drive wheels 10, 10 are attached to the lower ends thereof, respectively. These drive wheels 10, 10 are provided at intervals so as to straddle the ridge A, and rotation of the engine 1 is controlled by the main gear box 2, the support cylinders 7, 7,
The body 6 is propelled by being transmitted through the rotating barrels 8 and the transmission cases 9 and 9.

As shown in FIG. 1, a cylinder 11 is provided on a pipe frame 3 and a horizontal rod 13 is attached to a rear end of a piston rod 12 extending from the cylinder 11. As shown in FIG. 2, the arm 1
When the piston rod 12 is pushed out later, the transmission cases 9 and 9 turn clockwise in FIG. When the piston rod 12 is pulled back, the driving wheels 1
0, 10 is made to rise.

As shown in FIGS. 2 and 3, a ring 16 is rotatably mounted on the inner side of the right rotating cylinder 8, and a turning wheel 18 is provided at the rear end of a supporting leg 17 extending from the ring 16. A swivel cylinder 19 is provided on the pipe frame 3, and a rear end of a piston rod 20 projecting backward from the pipe frame 3 and a rear end of an arm 21 extending upward from the ring 16 are connected to a rod 22.
When the piston rod 20 protrudes backward,
The support leg 17 rotates clockwise in FIG. 1 to push down the turning wheel 18, and conversely, when the piston rod 20 is pulled back, the turning wheel 18 is raised. The turning wheel 18 is located at an intermediate portion between the left and right driving wheels 10 and 10 and advances along the upper surface of the ridge A. When the turning wheel 18 descends, the height of the ridge A is increased in a general field.
The fuselage 6 can be lifted so that the lower end of 10 reaches slightly above the upper surface of the ridge A. Therefore, the turning cylinder 19 constitutes a wheel lowering device for independently lowering the turning wheel 18. When the cylinder 11 and the turning cylinder 19 are linked so that the driving wheels 10 and 10 rise when the turning wheel 18 moves down,
This is convenient because the amount of movement of the turning wheel 18 can be reduced. Further, the rotation of the engine 1 may be transmitted to the turning wheel 18.

As shown in FIG. 1, a pair of left and right levers 23, 2
Idling wheels 24, 24 are provided at the lower end of 3 respectively, and their upper ends are connected to the horizontal rod 13 by rods 25, 25, and these idle wheels 24, 24 also move up and down above and below the driving wheels 10, 10. It is made like this. Therefore, the airframe has a total of five wheels including left and right drive wheels, left and right idler wheels, and turning wheels. The vertical movement of the drive wheels 10, 10 is performed by manually supplying and discharging oil to and from the cylinder 11, and by supplying and discharging the rotation of a sensor 26 that advances along the upper surface of the ridge A.

A seedling mounting table 27 is supported so as to move left and right below the pipe frame 3, and a lead cam shaft 28.
It is made to move right and left with a certain width by the rotation of.
At the end of the first turning case 29, the second turning case 30 turns so that the transplanting rod 31 at the end turns in the same posture up and down a long orbit. The transplanting rod 31 is attached to the seedling mounting table 27.
The seedlings for one plant on the seedling mounting table 27 are taken out, transplanted on the upper surface of the ridge A, and then raised. It should be noted that holes or grooves can be provided in advance at the positions where the seedlings are to be transplanted.

As shown in FIGS. 1 and 4, a crawler-type pressure reducer is constructed. That is, the support rod 32 is provided downward from the rear end of the bevel gear box 5. The left end of a support frame 33 that is shaped like a triangle when viewed from the side and that has a gate shape when viewed from the front and back is fixed to the lower end of the support rod 32. The front ends of the pair of left and right support frames 34, 34 are rotatably attached to the lower ends of the support frames 33, and the rear ends thereof are pushed down by the respective springs 35, 35. Three front and rear idler wheels 36, 36, 36 are rotatably mounted inside the respective support frames 34, 34, and endless bands 37, 37 are wound around the left and right idler wheels 36, 36, 36, respectively. . And these endless belts 37, 3
Numeral 7 passes right and left of the seedling transplanted by the transplanting rod 31 and pushes the soil in that part into the inside to suppress the pressure. Therefore, the endless belts 37, 37 can be slightly wider at the tip when viewed from above and below, or slightly wider at the top when viewed from the front and rear. The endless belts 37, 37 are wrapped in a sled shape when viewed from the side, in a sled shape, so that the seedlings are transplanted to the ridge A slightly in front of the contact point between the lower surface and the upper surface of the ridge A. It is good to configure.

As shown in FIG. 2, a handle pipe 38 extends upward from the middle of the bevel gear box 5 to the rear of the bevel, and a fork 39 is fixed to the rear end thereof. It has become. As described above, this field effect transplanter is provided with the left and right drive wheels 10, 10 and the left and right idler wheels 24, 24 straddling the ridge A, and is disposed at the intermediate portion between the left and right drive wheels 10, 10 by the operation of the turning cylinder 19. The left and right driving wheels 10 and 10 and the left and right idle wheels 24 and 24 are provided so as to float above the upper surface of the ridge A by lowering one turning wheel 18 independently with respect to the body 6. .

Therefore, during the seedling planting operation, the machine body 6 travels across the ridge A by the left and right drive wheels 10, 10 and the left and right idler wheels 24, 24. Then, when the user tries to turn at the end of the ridge A, one turning wheel 18 is independently lowered by the operation of the turning cylinder 19. Then, the turning wheel 18 descends to the upper surface of the ridge A and supports the body 6 with the turning wheel 18, and the left and right drive wheels 10, 10 and the left and right idler wheels 24, 24 rise above the upper surface of the ridge A.
Therefore, the operator operates the cat wheel with the handle 39 so as to make a single turn, and easily turns the airframe 6 around the turning wheel 18 by 180 ° or moves the airframe 6 to the adjacent ridge A. Can be replaced. The left and right inclinations of the body 6 and the left and right drive wheels 10, 10, the left and right idler wheels 24,
The collapse of the ridge A by the turning wheel 24 and the turning wheel 18 is reduced,
