Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a vegetable transplanter that sequentially plants vegetable seedlings in a field.

``Prior art'' Conventionally, as shown in Japanese Patent Application Laid-Open No. 58-205405, a transplanting section for planting seedlings in a transplanting groove and a covering ring for covering the transplanted seedlings with soil are provided, and the seedlings are continuously placed on the top surface of the ridge. I have mastered the planting technique.

``Problems to be Solved by the Invention'' In the above-mentioned prior art, the soil-covering ring slips, making it impossible to properly cover and suppress the soil, and the seedling holder in the transplanting section cannot be rotated in proportion to the moving speed. There were problems such as the spacing between seedlings tending to be uneven.

"Means for Solving the Problems" However, the present invention includes a transplanting section that feeds seedlings into a transplanting trench formed by a trenching disc, and a covering ring that covers soil over the seedlings transplanted into the transplanting trench. The vegetable transplanter is characterized in that a driving member for forcibly rotating the soil covering wheel is provided, and a ground contact driving wheel for driving the seedling holder of the transplanting section is arranged on the transplanting trajectory of the traveling wheel. That is.

``Action'' Therefore, it is possible to prevent the soil-covering wheel from slipping and obtain soil-covering and compaction functions properly, and also to drive the seedling holder by the ground-contact driving wheel to plant seedlings at uniform planting intervals. Since the ground drive wheel moves in the same place as the wheels (between the ridges), the shape of the top surface of the ridge does not collapse due to the ground drive wheel, and moreover, the ground drive wheel moves in a place that is harder than the top surface of the ridge, resulting in stable seedlings. The holder driving force can be obtained, and the driving function of the soil covering ring and seedling holder can be improved and the handling operability can be easily improved compared to the conventional method.

"Embodiment" An embodiment of the present invention will be described below in detail based on the drawings.

As shown in FIGS. 4 and 5, the front end of the planting frame 13 is connected to the fixed pivot shaft 2 of the main frame 2.
The frame 1 is supported in a vertically swingable manner.
The rear end of 3 is suspended from the machine frame 2 via a chain 25 in a height-adjustable manner. In addition, the ground driving wheel 17 connects the upper end of the support arm 27, which pivotally supports the driving wheel shaft 26, which is the ground PTO, to the counter shaft 2.

1 and compression spring 32, the ground driving wheel 17 is elastically supported by the machine frame 2 so that its mounting height can be adjusted. Furthermore, a fleece sprocket 35 is installed on the bracket 33 at the rear end of the planting frame 13 via a shaft 34, and the sprocket 35
The multi-stage sprocket 3 for input speed change of the seedling transplanting section 12
6 through a chain 37. The sprocket shaft 34 is interlockingly connected to the countershaft 28 through sprockets 38, 39 and a chain 40, and the countershaft 28 is interlockingly connected to the driving wheel shaft 26 through sprockets 41, 42 and a chain 43. The holder 14 of the seedling transplanting section 12 is driven by rotation.

Note that 44 and 45 are lugs that protrude from the outer periphery of the drive wheel 17.

The present embodiment is constructed as described above, and during the current work, seedlings are planted by the holder 14 of the transplant unit 12 in the transplant groove formed on the ridge by the groove-making disk 9, and then covered with soil. ring 1
The planted seedlings are covered with soil by the soil covering/suppressing action in step 6. Further, while the machine is running, the ground driving wheel 17 rotates, thereby driving the seedling holder 14 of the transplanting section 12, and the seedlings sequentially supplied to the holder 14 are planted in the transplanting groove of the ridge.

In addition, in this case, since the driving wheel 17 and the soil covering wheel 16 have separate structures, both the driving and soil covering functions are performed reliably under optimal conditions compared to a single structure.
Moreover, since the lugs 44 and 45 do not directly act on the ridges during covering with soil, the shape of the ridges can be well maintained without being damaged even after planting.

Furthermore, the ground driving wheels 17 are the front and rear wheels 4 and 7.
Since the drive wheels 17 are disposed in the middle of the front wheels 7, the drive wheels 17 pass through the track of the front wheels 7, and driving is performed more reliably.
Traces can be erased by

FIG. 6 shows another example of a modified structure, in which the drive wheel shaft 26 is connected to the counter shaft 28 supported by the fixed bracket 29a of the planting frame 13 via each sprocket 41, 42 and a chain 43. At the same time, a multi-stage sprocket 36, a multi-stage idle sprocket 47, and an idle sprocket 4 are connected to the input drive shaft 46 of the implantation part 12.
8. The countershaft 28 is interlocked and connected via the sprocket 39 and the chain 49, so that the rotation of the drive wheel shaft 26 is directly input from the countershaft 28 to the input drive shaft 46 of the implantation part.

FIGS. 7 to 8 show still another example of a modified structure, in which a lug 49, which is a grounding drive part, is provided protruding from the outer periphery of the soil covering ring 16, and performs both soil covering and grounding driving functions. The wheel body 50 is formed into a single wheel body 50, and the wheel body 50 is rotatably supported by a fixed support shaft 51, and the fixed bracket 52 of the support shaft 51 is oscillatably rotated with low torque via a shaft 53 and a swing arm 54. A rotary body 56 attached to the motor 55 is pressed against the inner peripheral surface of the soil covering wheel 16 by the force of a spring 57 that biases the arm 54. It is composed of Normally, the rotating body 56 is rotated with low torque, and when the wheel 16 slips during rotation of the soil covering wheel 16, the rotating body 56 applies auxiliary torque to the soil covering wheel 16, and as a result, the soil covering wheel 16 rotates. This eliminates the inconvenience of a drop in performance due to a slip accident, etc., and the planting speed of the transplant section 12 can also be maintained at a substantially constant level. In addition, the wheel body 49 may be connected to the four wheel axes using a chain means or the like, or the wheel body 49 may be brought into contact with the four wheel surfaces for forced drive. Furthermore, a torque limiter may be added to the forced drive using a belt transmission means or the like. It is also possible to have a configuration in which they are used together.

"Effects of the Invention" As is clear from the above embodiments, the present invention has a transplanting section 12 that feeds seedlings into a transplanting trench formed by a trenching disk 9, and a covering soil that covers the seedlings transplanted into the transplanting trench. A drive member 55 for forcibly rotating the soil-covering wheel 16 in the vegetable transplanting machine equipped with a wheel 16.
In addition, the seedling holder 1 of the transplanting section 12 is provided.
The ground driving wheel 17 for driving the running wheel 4
The soil-covering wheels 16 can be prevented from slipping, and the soil-covering and compacting effects can be properly achieved. Seedlings can be planted at a suitable planting interval, and since the ground drive wheels 17 move in the same place (furrow) as the running wheels 4, the shape of the top surface of the ridge does not collapse due to the ground drive wheels 17. The ground driving wheel 17 moves in a place that is harder than the top surface of the ridge, and stable driving force for the seedling holder 14 can be obtained, and the soil covering wheel 16 can be moved in a place that is harder than the top surface of the ridge.
Moreover, it is possible to easily improve the drive function of the seedling holder 14 and the handling operability.
