Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a device for removing fixed soil in a transplanting hole opening device in a transplanting machine that plants seedlings while making holes in the transplanting surface.

BACKGROUND ART Conventionally, in the cultivation of tobacco, lettuce, Chinese cabbage, etc., seedlings are planted using a transplanter equipped with a transplanting hole opening device that is raised and lowered by a link mechanism. Here, when the transplant hole opener descends while holding the seedling, it pierces the transplanting surface to make a transplant hole, and opens at the timing of rising to allow the seedling to fall into the transplant hole.

Problems to be Solved by the Invention As the work of planting seedlings continues, soil 2 adheres to the outer peripheral surface of the transplant hole opener 1 as shown in FIG. 13 and gradually becomes firmly fixed. If the planting operation is continued with the soil 2 stuck to the outer circumferential surface of the transplant hole opener 1, the stuck soil 2 will break up the soil around the periphery of the transplant hole 3 and cause the seedlings 4 to grow as shown in FIG. Fill it or
In addition, as shown in Figure 15, the collapsed soil is buried in the transplant hole.
The seedlings 4 fall to the bottom, making the planting depth of the seedlings 4 unstable and causing them to be planted at an angle. The seedlings 4 planted under such conditions have poor growth, resulting in a decrease in yield.

Therefore, it is necessary to remove the soil 2 stuck to the outer peripheral surface of the transplant hole opener 1, and this removal work is performed manually by an operator. For this reason, it is very time-consuming and the work efficiency of the planting work is reduced, and the removal work is performed in a bent-over position, which increases the fatigue of the worker.

Means for Solving the Problems In a transplanting machine having a transplanting hole device equipped with a divided bucket that moves up and down in an elliptical trajectory and pierces the transplanting surface at predetermined intervals to transplant seedlings, the transplanting hole device A soil removing body was provided close to the divided bucket at the ascending locus position and the descending locus position.

Function If soil adheres to the outer circumferential surface of the divided bucket of the transplanting hole opening device, the fixed soil will interfere with the soil removal body during the lifting and lowering process of the transplanting hole opening device and will be automatically removed. It is possible to increase the yield by preventing soil stuck to the surface from collapsing the periphery of the transplant hole and burying or tilting the planted seedlings.

Embodiment A first embodiment of this invention will be described based on FIGS. 1 to 3. An engine 7 is mounted on the front part of the chassis 6 of the self-propelled transplanter 5, and a transmission case 8 is fixed to the approximate center of the chassis 6. The input shaft 9 is located at the top of the transmission case 8.
The engine 7 is also provided with an output shaft 10, an input pulley 11 fixed to the input shaft 9 and an output pulley 12 fixed to the output shaft 10.
A V-belt 13 for power transmission is wound between the two. An axle 14 is provided at the lower part of the transmission case 8 and extends in the left-right direction perpendicular to the direction of movement of the transplanter 5. At both ends of the axle 14, the upper part of the transmission case 15 is aligned with the axis of the axle 14. It is connected so that it can rotate freely. Transmission case 15
A rotating shaft 16 is provided at the bottom of the rotating shaft 1.
A rear wheel 17 is connected to the wheel 6. Incidentally, a sprocket, a chain, etc. for transmitting power from the axle 14 to the rotating shaft 16 are housed in the transmission case 15. Further, a front wheel axle 18 extending forward is connected to the transmission case 15, and the front wheel axle 18 extends forward.
A front wheel 19 is attached to the tip of the wheel 8.

Approximately at the center of the chassis 6 is a telescopic hydraulic cylinder 20, which is driven by the hydraulic cylinder 20 and connects the transmission case 15 to the axle 1.
A link mechanism 21 that rotates about the axis of 4 is provided. Further, a handle 22 is connected to the rear part of the chassis 6, and further, a handle 22 is connected to the rear part of the chassis 6.
A rotary pot 23 is provided which rotates within a predetermined horizontal plane by a driving force from the rotary pot 23.

Next, a link mechanism 24 that extends rearward and moves up and down by the driving force from the engine 6 is provided, and the link mechanism 24 is located below the rotary pot 23 and follows a predetermined elliptical trajectory at the rear end of the link mechanism 24. The transplant retractor 25, which moves up and down in a drawing, is frozen. The transplant hole opener 25 is comprised of a cylinder 26 for receiving seedlings dropped from the rotary pot 23, a pair of divided buckets 27 that can be opened and closed in the front and rear directions, and the like.

A pair of left and right stays 28 that extend rearward and are located below the handle 22 are fixed to the rear part of the chassis 6. A substantially U-shaped mounting stay 29 is fixed at the position. Furthermore, these mounting stays 2
A plate-shaped soil removing body 30 located close to the vertical locus of the transplant hole opener 25 is connected to 9 by bolts 31 .

In such a configuration, first, the transplanting work of seedlings will be explained. The transplanter 5 is positioned so as to straddle the ridge and is run. As the transplanter 5 moves, the rotary pot 2 is moved by the driving force from the engine 6.
3, the transplant retractor 25 connected to the link mechanism 24 moves up and down in an elliptical trajectory. The transplant hole opener 25 receives the seedlings that have fallen from the rotary pot 23 at the timing when it rises to approximately the highest position, pierces the transplanting surface of the ridge to make a transplant hole when descending, and then opens the divided bucket pot at the timing when it starts to rise again. 27 is opened back and forth to allow the seedlings to fall into the formed transplant hole, and the seedlings are planted.

Next, as the seedling planting work continues, soil is stuck to the outer circumferential surface of the divided bucket 27, and the amount of soil fixed gradually increases. When the amount of adhesion reaches a certain amount,
Eventually, the fixed soil comes to interfere with the tip of the soil removing body 30. When the transplant hole opener 25 rises, the soil stuck to one of the divided buckets 27 located on the rear side interferes with the soil removal body 30 located on the rear side and is removed. Further, when the transplant hole opener 25 descends, the soil stuck to the other divided bucket 27 located on the front side interferes with the soil removal body 30 located on the front side and is removed. Therefore, the soil stuck to the outer peripheral surface of the divided bucket container 27 is automatically removed, and moreover, more than a certain amount of soil is prevented from sticking to the outer peripheral surface of the divided bucket container 27. For this reason, the split bucket 2
The soil fixed to the outer peripheral surface of the container 7 interferes with the periphery of the transplant hole and collapses the transplant hole, thereby preventing the planted seedlings from being buried or the planted state of the seedlings from being tilted.

Next, a second embodiment of this invention will be explained based on FIGS. 4 to 6. Incidentally, the same parts as those explained in FIGS. 1 to 3 are indicated by the same reference numerals, and the description thereof will be omitted (the same applies below). In this embodiment, the soil removing body 32 is fixed to the mounting stay 29 with a bolt 31, and the soil removing body 32 is fixed to the mounting stay 29 with a bolt 31.
An arc-shaped notch 33 having such a shape is formed on the outer peripheral surface of the divided bucket bag 27 at a portion facing the second divided bucket bag 27. Therefore, the soil is removed by the peripheral edge of the notch 33 interfering with the soil fixed to the outer peripheral surface of the divided bucket 27. Further, since the notch portion 33 has a shape that conforms to the outer circumferential surface of the divided bucket can 27, soil stuck to the side outer peripheral surface of the divided bucket can 27 can be reliably removed.

Note that the shape of the notch 33 formed in the soil removing body 32 may be triangular, square, or polygonal as shown in FIGS. 7 to 9.

Next, a third embodiment of this invention will be explained based on FIG. 10. In this embodiment, the soil removing body 34
An elongated hole 35 is formed in the elongated hole 35, and the soil removing body 34 can be attached to the mounting stay 29 along the elongated hole 35 so that the position can be adjusted in the front and rear directions. Therefore,
The distance between the outer circumferential surface of the divided bucket bag 27 and the soil removing body 34 can be adjusted, and by narrowing this distance, the amount of soil that sticks can be reduced.

Next, a fourth embodiment of this invention will be explained based on FIGS. 11 and 12. In this embodiment, the soil removing body 36 is made of an elastic member. Therefore, the soil removing body 36 may be installed close to a position where the soil removing body 36 directly interferes with the outer circumferential surface of the divided bucket 27, and soil adhesion to the outer circumferential surface of the divided bucket 27 can be almost completely prevented. This makes it possible to prevent

Effects of the device This device has a soil removing body placed close to the trajectory of the transplant pore opening device as described above, so that the soil removal body is attached to the outer circumferential surface of the transplant pore opening device during the process of raising and lowering the transplant pore opening device. Fixed soil can be automatically removed by interfering with the soil removal device, and as a result, the soil stuck to the outer surface of the transplanting hole breaks the periphery of the transplanting hole, making it difficult to bury or replant the seedlings. It is possible to prevent the seedlings from tilting, improve the growth of the seedlings and increase the yield, and eliminate the need for manual removal of stuck soil, making it easier to plant the seedlings. This has the effect of improving efficiency and reducing the amount of labor required by workers.
