Description

[Detailed Description of the Invention] The present invention relates to a transplanter, and relates to the provision of a transplanter that is intended to accurately and uniformize the planting depth of seedlings when planting the seedlings.

Conventionally, in a transplanter equipped with a transplanter main body that supplies the seedlings to a trench to transplant seedlings, and a conveyor device that supplies the seedlings to the main body, it is difficult to manually transfer the seedlings to the conveyor device. Supply was made based on the operator's experience and intuition.

Therefore, when seedlings are fed to the conveyor device, the position of the root of the seedling changes in various ways. This has caused many problems in the transplanting work because the feeding of seedlings to this conveyor device requires precision in positioning.

The present invention was devised in view of such conventional problems, and its features are: A transplanter is provided with a conveyor device for supplying seedlings to the main body, and a gauge member for positioning the roots of the seedlings with respect to the supply of seedlings to the conveyor device is provided, and the gauge member moves in the longitudinal direction of the supplied seedlings.

Furthermore, the planting device 31 has a main body portion of the planting device, and the main body portion is connected to a main body shaft 75 extending horizontally to the axis of the swinging frame 36 via bearings 74 , 74 . , a pair of flexible elastic clamping discs 76, 76 made of rubber material, resin material, etc. are attached to the main body shaft 75 in a spaced-apart manner facing each other, and the clamping discs 76, 76 are A plurality of pressing rings 77 are provided on the outside of the arc portion extending from the front part to the lower part, and are freely rotatable around a radial axis centered on the main body shaft 75. The wheel axle 78 is fixed to an arcuate bracket 79 that is detachably attached to the swing frame 36. And the clamping disc 7
6 near the front of the 3rd and 4th conveyors 55, 56
The lower openings of both conveyors 55,
The seedling 42 transferred downward at 56 is guided in that position between the two clamping discs 76, and the clamping discs 7 are brought closer by the left and right pressing wheels 77, 77.
Next, the seedlings 42 are held between the holding discs 76 and 76 and transferred backward and downward in an arc of about 90 degrees, and the seedlings are held at the rear from the pressing ring 77 at the lower end. In a vertical position with the root portion 42a as the lower end, the clamping is released and it is made to stand on its own within the groove 41.

The earth-covering vessel 32 includes a pair of left and right rolling wheels 81, 81 that are rotatable around an inclined shaft 80 pivotally supported at the rear end of the swinging frame 36.
1 is in an inclined position so as to gradually move away from each other as it moves upward and/or forward. As the vehicle body 13 advances, the rolling wheels 81 roll on the ground due to the resistance, and the soil of the ridges 40 is rolled by both rolling wheels 81, 81.
This soil is raked up between the soil and supplied into the trench 41 to embed the roots 42a of the seedlings 42 in the ridges 40, and to compress both sides of the seedlings 42.

The tilting shaft 80 and the main body shaft 75 and the main body shaft 75 and the interlocking shaft 62 are interlocked and connected through a chain wheel 82 and a chain 83 winding, respectively, and the main body shaft 75 is driven by the rolling of the rolling wheel 81 on the ground. , the clamping disc 76 rotates as described above, and
The rotation of the interlocking shaft 62 rotates the conveyor device via the bevel gear 61 and the bevel pinion 60, and these devices are synchronously driven by appropriate speed changes etc. in order to plant the seedlings 42. However, in this case, the interlocking shaft 62 and the main body shaft 75 may each be provided with an independent drive source.

A forward-facing seat 84 is provided at the top of the vehicle body 13, and a safety frame 85 on the side of the seat 84 is provided with an operating lever 86 for operating a main clutch for connecting and disconnecting the engine 5 and for operating a travel gear change. The operator on the seat 84 can step on both tread bars 26, 26 so that the operator on the seat 84 can feed the seedlings 42 on the seedling table 63 to the conveyor device at predetermined intervals in a longitudinal posture in the front and back direction. The seats 84 are arranged as shown in FIG.
The operating lever 86 and the like constitute an operating section 87 for steering and planting operations.

A pair of left and right gripping rods 89, 89, which are bent rearward and serving as a lifting portion 88 of the vehicle body 13, are protruded from the rear of the vehicle body 13, that is, inside the main frames 14, 14. A steering clutch lever 90 is provided, the steering clutch lever 90
are interlocked and connected via Bowden wires 91 to steering clutches provided between the engine 5 and each traveling drive wheel 8, and when one steering clutch is disconnected by operating a steering clutch lever 90, one of the steering clutches can be turned off. Only the drive wheels 8 are rotated, and the transplanter 1 is rotated to change direction.

Next, the operation based on the above structure will be explained with particular reference to FIG.
forms grooves 41 along the ridges 40. Due to the above-mentioned progress, the rolling wheels 81 roll on the ground, and the rotation of the rolling wheels 81 drives the conveyor device and the main body of the planting device 31. From this state, the operator of the operation unit 87 sets the seedling 42 on the seedling platform 63 to the longitudinal direction, and the front side is set to the seedling leaf part 42b.
Then, the seedling root portion 42a in the parallel direction is supplied between the first and second conveyors 45 and 48 in an appropriate pitch. In this case, each seedling root portion 42a is positioned in contact with the gauge member 68, and is conveyed by the first conveyor 45 at an accurate position in the front and back direction, and is transferred to the first and second conveyors 45, 4.
It is supplied between 8 and 8 hours. Then, the supplied seedlings 42 are placed at the first position without changing their position in the front-back direction.
1. It passes between the second conveyors 45 and 48 and the third and fourth conveyors 55 and 56 and is supplied between the clamping discs 76 and 76, and then the clamping discs 76 and 76 cut the groove 41. The robot is sequentially transferred into the interior, and its angle is changed to a vertical position. Next, the seedling 42 is placed on the clamping disc 7
6, 76, and further, the seedlings 4 in the groove 41
The potter 32 is placed next to bury the roots 42a of the seedlings 42, and the transplantation of the seedlings 42 is completed by the suppressing action.

When there are no more seedlings 42 on the seedling platform 63, a portion of the seedlings 42 that have been loaded in advance on the seedling transport platform 12 in large quantities are transferred to the seedling platform 63, and the above-mentioned transplanting work of the seedlings 42 is continued. .

When the transplanting work for the ridge 40 is completed, first, the operator stands between the two support rods 22, 22, grasps and lifts the lifting part 78, and lifts the vehicle body 13 and the transplanting device 29 attached thereto, centering on the traveling drive rod 8. etc., rotated away from the ground surface. In this case, the swing frame 36 is also rotated upward by the spring 35. Then, the direction of the transplanter 1 is changed around the traveling drive wheel 8, or only one of the traveling drive wheels 8 is rotated by disengaging one of the steering clutches by operating the steering clutch lever 90. Rotate the transplanter 1 to change direction.

According to the present invention, the conveyor devices 45, 48, 5
5, 56, the seedling root portion 42a is attached to the gauge member 68.
In order to supply the seedlings 42 in a state in which they are positioned by
The seedling 42 to be transplanted after passing through has its root part 42a
The planting depth is accurate and uniform,
This is useful for porting work. Furthermore, by providing the gauge member 68, the seedlings 42 relative to the conveyor device can be
The supply can be done accurately with a simple operation, and from this point of view as well, it is very practical.
