Description

[Detailed explanation of the idea] [Industrial application field]

The present invention is a seedling box mounting device for a transplanter that transports and supplies seedlings with soil, such as paper tube seedlings, to the planting mechanism part using a conveyor for transplantation, and more specifically, a seedling box mounting device for a transplanter that transports and supplies seedlings with soil, such as paper tube seedlings, to the planting mechanism section for transplantation. The present invention relates to a seedling box mounting device that receives and places seedling boxes containing soiled seedlings.

[Conventional technology]

This kind of seedling box mounting device is known, for example, the one described in Japanese Patent Publication No. 7689/1989, is equipped with a seat on both sides of a conveyor for the worker to sit on and a stand on which the seedling boxes are placed. In this type of system, a worker sitting on a seat separates paper tube seedlings in rows from a seedling box placed on a stand, takes them out, and loads them onto a conveyor. The paper tube seedlings loaded on the conveyor are separated into individual plants during transportation, and good seedlings and bad seedlings are sorted out, and finally only good seedlings are supplied to the planting mechanism. automatically transplanted to the field.

[Problem that the idea aims to solve]

The above-mentioned work of loading paper tube seedlings onto the conveyor involves, of course, removing the empty seedling box and setting a new seedling box containing paper tube seedlings in a predetermined position facing the worker. Replacement work is required. For example, a group of paper tube seedlings grown using one standard paper pot of 70 rows x 20 rows weighs about 60 kg in total, and if you add the weight of the seedling box to this, the paper tube seedlings can be accommodated. Since the seedling box weighs approximately 70 kg, replacing the seedling box described above is a labor-intensive task. In addition, if the loading of the paper tube seedlings onto the conveyor is delayed due to the long replacement work time, the planting mechanism may not be able to plant the seedlings properly, resulting in missing plants, and in some cases, the transplanter may There are problems such as having to slow down or stop the vehicle. The purpose of the present invention is to solve the problem of replacing seedling boxes easily and quickly, and to cope with the fact that recent improvements in transplanting technology have made it possible to transplant at an increasingly high speed.

[Means to solve the problem]

The configuration of the seedling box mounting device of the transplanter of the present invention is as follows. It is equipped with a conveyor 2 that conveys soiled seedlings such as paper tube seedlings. A turntable 8 having a size on which a plurality of seedling boxes 11 can be placed is installed on the side of the conveyor 2. The turntable 8 is horizontally rotatably supported on the fixed base 3 via a plurality of rotating bodies arranged in a circle at predetermined intervals. Further, an engaging member 15 is provided that can be displaced in and out of a passage through which an engaged portion set on the turntable 8 passes. The engaging member 15 is installed at a position where it engages with the engaged portion when the seedling take-out port of the seedling box placed on the turntable 8 faces the conveyor 2. In the present invention, the rotating body may be a ball bearing or a roll bearing in addition to the axle 7, and it may be mounted on the fixed base 3 side or on the turntable 8 side. As the engaged part of the turntable 8, any part of the turntable 8 itself, such as a corner part, can be used directly, or a separately manufactured attachment can be attached to an arbitrary position of the turntable 8. You may also do so. Therefore, the engaging member 15 has the required configuration or shape corresponding to each of the above-mentioned engaged parts, and the engaging member 15 can be moved in or out of the passage of the engaged parts. Of course, the means for operating the possible support means need not be limited to hand-operated ones, but may also be of the foot-operated type.

[Effect]

By placing multiple seedling boxes containing soiled seedlings such as paper tube seedlings on a turntable, a worker can take out the soiled seedlings from the take-out port and load them onto the conveyor, and the seedling boxes are When it is empty, by removing the engaging member from the engaged part and rotating the turntable, you can easily move a new seedling box to face the conveyor, that is, the worker's side, and fill the new seedling box with soil. Seedlings can be loaded onto the conveyor.

【Example】

The illustrated embodiment will be described below. The seedling box mounting device of the present invention is mounted on a conventionally known type of transplanting machine that has a seat on which a worker sits and a table on which a seedling box is placed facing each other on both sides of a conveyor. 1 is the machine frame of the transplanting machine, 2 is a conveyor, and 3 is a planar circular fixed stand installed in the machine frame 1, and a pivot rod 4 is installed in the center thereof. Reference numeral 7 denotes wheels serving as rotating bodies arranged circularly at required intervals on the upper surface of the fixed base 3, and each wheel 7 is rotatably supported on the wheel support frame 5 by a shaft 6. In addition to the wheel 7, the rotating body may be, for example, a ball bearing, a roll bearing, or the like. Reference numeral 8 denotes a turntable having a rectangular plan view, which is mounted on each of the wheels 7, and has a pusher 9 attached to the center fitted to the upper end of the shaft rod 4, and rotates horizontally around the shaft rod 4. I am now able to do this. Reference numeral 10 denotes an annular rail attached to the lower surface of the turntable 8, which surrounds and is located outside the wheels 7, which are arranged in a circle at predetermined intervals. Reference numeral 11 denotes a conventionally known seedling box with surrounding walls erected on three sides of the bottom plate, the top and front sides are open, and the front side serves as a seedling outlet.
A group of paper tube seedlings P grown using one standard paper pot with 70 rows and 20 rows is stored. In this embodiment, the length of each side of the turntable 8 is approximately equal to the total length of the frontage and depth of the seedling box 11, so that the turntable 8 has a seedling box 11
A total of four seedling boxes 11 can be placed so that the left or right side of another seedling box 11 adjacent to the front side seedling take-out port is exposed (see Fig. 1). Reference numeral 12 denotes a support stand established on the machine frame 1, and a rotating rod 14 is attached to a horizontal shaft 13 supported at the upper end of the support stand so as to be able to rotate in the vertical direction. 15 is a planar hook-shaped engagement member whose corner is fixed to the inner end of the rotating rod 14; 16 is a weight fixed to the outer end of the rotating rod 14;
is provided with a force that rotates the engaging member 15 in a direction that lifts it up. Normally, the engaging member 15 is circumscribedly engaged with a corner portion of the turntable 8 to prevent the turntable 8 from rotating, but it pushes up the weight 16 and rotates it. When the above-mentioned circumscribed engagement by the engaging member 15 is released downward by rotating the movable rod 14, the turntable 8 becomes in a state where it can be easily rotated manually. When the turntable 8 is rotating, the engaging member 15 comes into sliding contact with the lower surface of the turntable 8. However, when the engaging member 15 coincides with the next corner, the rotary rod 14 rotates due to the action of the weight 16, and the engaging member 15 is automatically moved to the next corner. The rotation of the turntable 8 is stopped by the external engagement with the turntable 8. In the above, when the turntable 8 has stopped rotating due to the engagement between the engaged portion and the engaging member 15, any one of the seedling boxes 11 placed thereon can be used to remove the seedlings. The related parts are designed so that the mouth faces the conveyor 2. Therefore, a worker sitting on a seat across the conveyor 2 can easily take out paper tube seedlings P in rows from the seedling box 11 in front and load them onto the conveyor 2. In that case, seedling box 11
The replacement work can be easily performed by rotating the turntable 8. That is, when the seedling box 11 becomes empty,
When the engaging member 15 is removed from the engaged part and the turntable 8 is manually rotated, and the rotation is stopped by engaging the engaging member 15 with the next engaged part, the paper cylinder Next-ranked seedling box 11 containing seedlings P group
is automatically rotated to a predetermined position, so that the seedling outlet of the new seedling box 11 faces the front, that is, toward the operator, and the replacement of the seedling box 11 is easily completed. Note that the engaged portion of the turntable 8 is as follows:
The present invention is not limited to the above-mentioned corner portions, and an attachment having a desired configuration may be attached to any position on the turntable 8. Therefore, the engagement member 15 may also be configured in an appropriate manner depending on the attachment. It is a good idea to adopt one.

[Effect of the idea]

As is clear from the above description, the present invention provides the following effects. By placing a plurality of seedling boxes containing soiled seedlings such as paper tube seedlings in the required arrangement on the turntable, the worker takes out the soiled seedlings from the take-out port and loads them onto the conveyor. When the seedling box is empty, the engaging member is removed from the engaged part and the turntable is rotated.
A new seedling box can be easily placed facing the conveyor, that is, the worker's side, and the seedlings with soil in the new seedling box can be loaded onto the conveyor. Seedling boxes can be easily replaced by simply rotating the turntable, eliminating the need for replacing seedling boxes, which is a laborious task in the past, and shortening the time required for replacing seedling boxes, making it easier to transfer seedlings to the conveyor with soil. The loading work is not delayed, and therefore there is no risk of missing plants, and it is also possible to eliminate the need to slow down or stop the transplanter when replacing seedling boxes. Since the turntable is supported and installed so that it can rotate horizontally via a plurality of rotating bodies arranged in a circle at required intervals, it is possible for some of the seedling boxes on the turntable to become empty. However, the turntable rotates smoothly without losing balance, so you can easily replace the seedling box.
