Description

[Detailed description of the invention] This invention supports the seedling planting device by providing front support legs on both sides of the machine frame and rear support legs at the rear, and is located in the center of the guide bar. This invention relates to a seedling planting device for a riding rice transplanter in which a marker storage and locking piece is fixed to the bracket of the rear support leg.

In the case of riding rice transplanters that have a seedling planting device attached to the rear of the traveling machine via a parallel link, the seedling planting device is removed and stored during the off-season when seedlings are not being planted. Since the seedling planting device was not equipped with any supporting legs, the float, which is an airtight hollow body, had to be supported in an unstable state using logs, empty boxes, etc. to prevent it from being damaged. I didn't get it.

In addition, markers are rotatably attached to both ends of the guide bar installed at the rear of the aircraft frame, but these markers are long, measuring more than half the width of the aircraft, and can be folded. Even though it will be in a polymerized state in the center of the fuselage when folded and stored,
Conventional marker storage locking pieces are provided separately on the left and right sides, which is wasteful, and the mounting position must be selected each time so that the storage locking piece on the opposite side does not get in the way of the marker being folded and stored. It was necessary to install a storage locking piece.

The present invention was devised to eliminate the above-mentioned drawbacks, and when the seedling planting device is removed from the riding tractor, such as during storage, the front and rear support legs are simply held in an upright position. The seedling planting device is supported in a stable state to prevent damage to the float, which is an airtight hollow body, and the marker is stored and locked using the bracket of the rear support leg located in the center of the guide bar. A seedling planting device for a riding rice transplanter in which assembly is facilitated by fixing the pieces and storing and locking the marker in a state substantially parallel to the guide bar, while fixing the storage and locking pieces to the brackets of the rear support legs in advance. We aim to provide the following.

The configuration of the present invention will be described with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a riding tractor, and a seedling planting device 2 is attached to the rear of the riding tractor 1 via a parallel link 3 so as to be movable up and down and detachable. 4 is a seedling mounting table attached to the seedling planting device 2; 5;
6 is a seedling division planting claw, and 6 is a planter case. 7
The float 7 is formed into a hollow body with an airtight interior, and the float 7 is vertically movable relative to the machine frame 8 of the seedling planting device 2. 9 is hung horizontally behind the seedling planting device 2, and is connected to the planter case 6.
a guide bar that connects the guide bar 9;
A marker 10 is rotatably supported at both ends of the marker. 11 is a rear support leg fixed to the plate 12, and the rear support leg 11 is attached to a pivot pin 1 on a bracket 13 fixed to the central part of the guide bar 9.
4, it is pivoted so that it can be raised and lowered freely. Reference numeral 15 indicates an engagement hole drilled in the bracket 13, and reference numeral 16 indicates a lock pin fixed to the plate 12, and the lock pin 16 is fixed to the plate 12 when the rear support leg 11 is placed in an upright position or in a laid down position. is the engagement hole 15
The rear support legs 11 are engaged with each other to hold the rear support legs 11 in an upright state or a collapsed state. Reference numeral 14a designates a bullet for holding the rear support leg 11 in pressure contact with the brat 13 side. 17 is a storage locking piece for the marker 10,
It is fixed to the upper end of the bracket 13, and stores and locks the marker 10 in a substantially parallel state to the guide bar 9. A hook 18 made of an elastic material is fixed to the storage locking piece 17 so that the marker 10 is held in a pressed state on the storage locking piece 17.
Reference numerals 19 and 19 are front support legs, and the seedling planting device 2
It is pivoted to the left and right front of the body so that it can be raised and lowered freely.

The operation of the present invention constructed as described above will be explained. To support the seedling planting device 2 with support legs,
After activating the parallel link 3 and pulling up the seedling planting device 2, the front support legs 19, 19 and the rear support legs 11 are rotated downward and held in an upright state. Next, when the parallel link 3 is operated to lower the seedling planting device 2, the seedling planting device 2 is moved to the front and rear support legs 19, 1.
9 and 11. Therefore, when the seedling planting device 2 is removed from the riding tractor 1 during storage or the like, the seedling planting device 2, especially the float 7, will not be damaged at all.

On the other hand, the markers 10 that are pivotally supported at both ends of the guide bar 9 can be stored within the width of the machine by rotating toward the center of the guide bar 9, but in this case, the markers 10 are locked. Since the storage locking piece 17 is fixed to the bracket 13 of the rear support leg 11 which is fixed to the center of the guide bar 9, the marker 10 can be stored and locked in a substantially parallel state to the guide bar 9, and therefore, Since the marker 10 is integrated with the guide bar 9, there is no chance of it colliding with other objects.

In short, the present invention has a seedling planting device in which markers are rotatably pivoted on both sides of a guide bar installed at the rear of the machine frame, and the seedling planting device is attached to the rear of the traveling machine via a parallel link so that it can freely swing up and down. In a riding rice transplanter that is detachably attached, front support legs are pivotally supported on both sides of the machine frame of the seedling planting device so that they can be raised and lowered,
A bracket is fixed to the center part of the guide bar to pivotally support the rear support leg so as to be able to rise and fall freely, and a storage locking piece for a marker which is pivotally fixed to both sides of the guide bar is fixed to the bracket. When storing the seedling planting device or removing it from the tractor, the seedling planting device can be supported reliably and stably by simply placing the front and rear support legs in an upright position, so there is no need to worry about the float being damaged. This does not happen at all, and since the marker storage locking piece is fixed using the bracket of the rear support leg located in the center of the guide bar, there is no need to provide separate locking pieces for the left and right sides. In addition to eliminating waste, the storage locking piece can be fixed to the bracket of the rear support leg in advance, so the storage locking piece can be installed simply by attaching the rear support leg to the center of the guide bar. It is also possible to attach the marker at the same time, making assembly easier.Furthermore, the marker can be stored and locked in a state substantially parallel to the guide bar to reliably prevent it from colliding with other objects. This is effective.
