Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a seedling planting machine with a preliminary seedling mounting device that enables a good seedling feeding operation.

[Prior art]

In this type of conventional technology, the preliminary seedling loading device is configured to be movable between a seedling supply position to the main seedling loading device and a seedling supplying position to the preliminary seedling loading device, and is also configured to move from the preliminary seedling loading device to the main seedling loading device. There is a seedling transplanter equipped with a preliminary seedling mounting device in which the preliminary seedling mounting device is brought closer to the main seedling mounting device when feeding seedlings.

[Problem that the invention seeks to solve]

However, in the above-mentioned seedling planting machine, in order to replenish seedlings from the ridge to the backup seedling loading device when there are no seedlings in the backup seedling loading device, the backup seedling loading device is moved to the seedling supply position and the seedlings are replenished. If you continue to plant seedlings as they are, and eventually there are fewer seedlings on the main seedling loading device and you need to feed the seedlings, if you bring the spare seedling loading device closer to the main seedling loading device, the two may collide or the seedlings may not be fed properly. There were problems such as not being able to do so.

[Means to solve the problem]

In order to solve the above problems, this invention provides a preliminary seedling mounting device 1.
is configured to be movable between the seedling supply position for the main seedling loading device @2 and the seedling supplying position for the backup seedling loading device 1, as well as the preliminary seedling loading device! ! A seedling planting machine equipped with a preliminary seedling mounting device 1 configured to move the preliminary seedling mounting device 1 closer to the main seedling mounting device 2 when seedlings are supplied from the main seedling mounting device 1 to the main seedling mounting device 2, When the preliminary seedling loading device 1 is in the seedling supply position, the preliminary seedling loading device 1 is the main seedling loading device! ! This is a seedling planting machine with a preliminary seedling mounting device, characterized in that the seedling planting machine is configured to prevent the seedling from moving toward the second seedling.

〔Effect of the invention〕

Spare seedling loading device! 1 is in the seedling supply position, the spare seedling mounting device W1 is configured to prevent it from moving closer to the main seedling mounting device 2. While the preliminary seedling loading device 1 has been moved to the seedling supply position for replenishment, the main seedling loading device! In order to supply seedlings to 2, use the preliminary seedling loading device l as the main seedling loading device! 2), in that case, the preliminary seedling loading device 1 cannot be placed in the seedling supply position, so the preliminary seedling loading device 1 and the main seedling loading device 2 may collide or fail. This solves the problems of the conventional example, such as the inability to supply seedlings.

A steering post is erected at the rear of the bonnet 8, a control handle 13 is attached thereto, and a driver's seat 14 is provided at the upper rear part of the steering post.

The rice transplanting device 16 includes a main planting transmission case 15 that also serves as a frame connected to the rear end of the link mechanism 5, and sub-planting transmission cases 16 extending rearward at desired intervals. At the top of the mat, there are six seedling resting parts arranged in a row in the left and right direction, which are inclined so that the front side is on top, and are formed by the bottom plate 2a and the left and right side walls 2b, 2b so that one mat seedling can be placed thereon. The main seedling placement device is configured to be able to place 6 rows of seedlings! 2 is supported so that it can reciprocate from side to side, and a seedling planting tool 17 is installed at the rear of the sub-planting transmission case 16...
It is installed with a rotating crank and a swinging arm, and on the lower side,
Land leveling floats 18 are attached to the central part and both left and right sides of the rice planting device, making it a 6-row rice transplanting device.

Reference numeral 1 denotes a preliminary seedling placement device, and a main seedling placement device 2 configured to be able to place six rows of seedlings in parallel in the left and right direction.
A seedling mounting section 20 configured to be able to place six mat seedlings placed in parallel on each of the seedling scooping plates 19 in the left and right direction in correspondence with the seedling mounting sections for each one row. The left and right arms 21 and 21 extending downward from the front lower side of the seedling mounting section 20 are rotatably supported at the lower ends thereof, and are also rotatably supported on the upper surface of the rear differential case 11. The supported left and right front support arms 22, 22, and the upper part of the support body 23, which is rotatably supported under the center of the seedling mounting part 20 and extends from the upper surface of the rear differential case 11, are also rotatably supported. The hydraulic cylinder 24 is pivotally supported.

Stoppers 25 and 26 are provided to contact the front support arms 22 and 22, respectively, to prevent the preliminary seedling mounting M1 from rotating in the A direction and the mouth direction.

27 is a seedling supply lever that operates the hydraulic cylinder 24 to move the rear end of the preliminary seedling loading device 1 downward in a convex direction, tilting the preliminary seedling loading device @1, and putting the preliminary seedling loading device 1 into the seedling supply state. If it is rotated in two directions, the hydraulic valve 28 is switched to contract the hydraulic cylinder 24 and the preliminary seedling loading device 1 is activated.
It is provided so that the seedlings are supplied. In addition, 29 is a hydraulic pump, and 3o is a relief valve.

Reference numeral 31 denotes a blocking device for preventing rotation of the seedling supply lever 27 in two directions, and includes a lock pin 32 that comes into contact with the seedling supply lever 27 to prevent rotation in two directions;
2 in the E direction.

34 is a connecting wire, which connects the lock pin 32 and the front support arm 22 via a bullet 35,
In FIG. 1, when the preliminary seedling loading device 1 is in the state shown by the solid line, the connecting wire 34 pulls the lock pin 32 in a convex direction against the bullet 33, allowing the seedling supply lever 27 to rotate in two directions, and When the seedling mounting device 1 is in the state shown by the one-dot chain line, the connecting wire 34 is loosened and the lock pin 32 pops out in the E direction by the bullet 33 to prevent the seedling supply lever 27 from rotating in two directions.

The riding-type rice transplanter 3 configured as described above is placed in a paddy field, and the main seedling loading device is installed! 2 and the preliminary seedling loading device 1, each part is driven by the engine, the rice transplanting device fi6 is towed by the riding type traveling device 4, and the seedling planting tool 17 is reciprocated from side to side. Seedlings are divided into individual plants from a seedling mounting device 2 and planted on the leveled soil surface using a leveling float 18.

When there are fewer seedlings placed on the main seedling placing device 2, the main seedling placing device it2 and the preliminary seedling placing device 1 are switched to the second seedling placing device it2.
When the horizontal phases match as shown in the figure, stop the machine, operate the seedling supply lever 27 in two directions, and tilt the preliminary seedling loading device 1 in a convex direction until it touches the upper end of the main seedling loading device 2. For example, the operator can easily feed seedlings to the main seedling loading device 2 by holding the seedling scooping plate 19. When the seedling supply is completed, the seedling supply lever 27 is operated in the opposite direction to return the preliminary seedling loading device W1 to its original state.

Next, a spare seedling mounting device! When all the seedlings on the top 1 have been fed and there are no more seedlings left, the rear of the machine rests on the ridge and stops, and the preliminary seedling loading device TL is moved to the stopper 26 on the front support arm 2.
The seedlings are moved in the G direction until they come into contact with each other, and the seedlings are supplied from the ridge to the preliminary seedling mounting device 1.

In this state, since the connecting wire 34 is loose, the lock pin 32 is ejected by the bullet 33 in the E direction, preventing the seedling supply lever 27 from rotating in two directions, and tilting the preliminary seedling loading r111. I can't speak. Therefore, the preliminary seedling mounting device 1 is attached to the stopper 26 on the front support arm 22.
After planting the seedlings, I forgot to return it to the original position after moving it in the direction of G until it touched the main seedling loading lol! Even if the seedling supply lever 27 is operated in two directions to tilt the preliminary seedling loading device 1 in a convex direction until it touches the upper end of the main seedling loading device 2, the seedling supply lever 27 will not work properly. 27 cannot be operated in two directions, thereby preventing collision between the preliminary seedling mounting device 1 and the main seedling mounting device 2 or failure to properly supply seedlings.

In addition, in the above embodiment, a passenger-type traveling device is used! Although an example in which the present invention is implemented in a riding type rice transplanter equipped with a rice transplanting device 6 at the rear of the rice transplanter 4 has been shown, it is also possible to implement the present invention in a riding type agricultural machine equipped with other seedling planting devices such as a vegetable transplanting device. Furthermore, the present invention may be implemented in a walking type seedling planting machine.
