Description

[Detailed description of the invention] The present invention relates to a seedling stopper device for a rice transplanter in which the seedling intermittent vertical feeding device corresponding to the seedling stopper is automatically switched to a non-operating state when the seedling stopper is used. .

In rice planting work using a multi-row rice transplanter, when planting seedlings at the edge of a field, it may be necessary to reduce the number of planting rows on the rice transplanter according to the field conditions such as the planting width. In such cases, the mat seedlings placed on some of the multiple seedling stands must be securely stopped so that they do not come into contact with the scraping area of the planting claws, and the vertical feeding of the seedlings for this purpose must be avoided. A seedling stopper device is required for each seedling stand.

However, if a seedling stopper device that prevents vertical feeding is applied to some of the multiple seedling platforms at a position forward of the intermittent vertical seedling feeding device in the direction of seedling feeding, strain may be placed on the vertical feeding device that continues to operate. This has the disadvantage of damaging the seedling bed on the seedling stand on which the stopper is applied.

Conversely, if the seedling stopper device is installed above the seedling feeder than the seedling intermittent vertical feeding device, the above-mentioned inconvenience will be solved, but each time the seedling stopper device is used, the seedlings will not be placed on the seedling stand. The seedlings placed on the mat must be lifted by hand to the installation position of the seedling stopper device located at a high position.
This is not just a nuisance, but there is a risk of damaging the seedlings when lifting the matted seedlings by hand.

The present invention solves the above-mentioned inconveniences all at once, and is a multi-row rice transplanter in which a separate intermittent vertical feeder for seedlings and a seedling stopper are provided for each seedling table for storing and placing mat seedlings. Each seedling stopper and its corresponding intermittent vertical feeder for seedlings are linked and connected, and in response to switching operation of each seedling stopper to activate or deactivate, the intermittent vertical feeder for seedlings becomes inactive. Alternatively, by configuring the device to switch to the operating state, when the seedling stopper is used, the drive of the intermittent vertical feed device for seedlings corresponding to the seedling stopper can be automatically switched to the dormant state, thereby allowing multiple seedlings to be loaded. An object of the present invention is to provide a seedling stopper device for a rice transplanter that can reliably prevent damage to seedlings and strain on the intermittent vertical feed device for seedlings even if the seedling stopper is used for a part of the table. .

The structure of the present invention will be explained with reference to an embodiment shown in the drawings. Reference numeral 1 is a multi-row rice transplanter, and an engine 2 is mounted on the front of the rice transplanter 1, and an engine 2 is mounted on both sides. The aircraft propulsion wheels 4, 4 are mounted on the shafts via the swing cases 3, 3 so as to be able to move up and down, and a float-shaped rice slide 5 is mounted below.
It is equipped with a treadmill that allows it to slide while leveling the rice field.

6 is a seedling platform, and the seedling platform 6 has a driving operation handle 7.
The left and right reciprocating drive mechanism 8 is located above the
It is installed so that it can freely reciprocate from side to side.

Although not shown, a plurality of seedling stands 6 are arranged in series in the width direction of the machine via partition walls, and mat seedlings A are stored and placed on each seedling stand 6.

9 is a seedling planting device, and a planting claw 10 of the seedling planting device 9
The function is to sequentially divide the seedlings for unit planting from the seedling take-out port 11 provided at the lower end of the slope of the seedling holder 6 and to plant them into the rice field.

Reference numeral 12 denotes a seedling holding body provided at the lower end of the slanted side of the seedling take-out side of the seedling table 6. The seedling holding body 12 is horizontally suspended above the seedling table 6 at an appropriate distance. It guides the leaf stem of A in a backward-slanting manner.

12a is an apron. Reference numeral 13 denotes a seedling intermittent vertical feeding device located near the lower end of the slope of the seedling platform 6 and separately arranged for each seedling platform 6; It consists of a driving roller 14 and a driven roller 15 which are pivotally supported on the back side, and a flat belt 16 which is suspended between these rollers 14 and 15.

Although not shown, the drive roller 14 is interlocked with the drive side of the machine body, and is connected to the front end of the mat seedling A in the feeding direction.
By rotating in the direction of the arrow in FIG. 5 every time the seedling division for a row is completed, the mat seedlings A on the seedling platform 6 are intermittently fed out toward the seedling removal side.

On the other hand, 17 is a seedling stopper, and the seedling stopper 1
7 is closely opposed to the driving roller 14 side of the intermittent vertical feeding device 13 for seedlings, and is attached to each seedling stand 6 via a bracket 17a and a fulcrum shaft 17b so as to be freely upright and tiltable.

Reference numeral 18 denotes a belt tension that performs a clutch action for the seedling intermittent vertical feeding device 13. Its base end is fixed to the bracket 17a of the seedling stopper 17, and a tension roller 18a is mounted on the tip end. The seedling stopper 17 and the belt tension 18 are configured to rotate integrally about a fulcrum shaft 17b as a rotation fulcrum.

19 is a locking device that locks the belt tension 18 in a detachable manner.

FIG. 6 shows another embodiment in which the seedling platform 6 is cut in the width direction at a position close to the front of the seedling intermittent vertical feeding device 13 and divided into two parts, and the front portion 6' of the seedling platform 6 is divided into two parts. is configured to be freely rotatable around a fulcrum shaft 17b, and by tilting the front portion 6' upward to a position close to the seedling presser 12, the seedlings are stopped in cooperation with the seedling presser 12. This is what I did.

FIG. 7 shows still another embodiment, in which a gear 20 and a seedling intermittent vertical feeding device 13 are interlocked and connected to the drive side of the machine body.
A gear 21a fixed to one of the rollers 21 is interlocked and connected via an intermediate gear 23 pivotally supported at the tip of a tension arm 22.

In a configuration like the above, if you want to stop the vertical feeding of seedlings on some of the seedling stands 6, the belt tension 18 can be adjusted by raising the seedling stopper 17 to the state A□ as shown in FIG. Since it rotates to the position al using the fulcrum shaft 17b as a rotation fulcrum, the belt tension 18 can be locked at the a position by the locking device 19.

In this case, the clutch of the seedling intermittent vertical feeding device 13 is disengaged, and the vertical feeding action of the mat seedlings A is stopped.

Therefore, when the seedling stopper 17 is used, the drive of the intermittent vertical feeding device 13 for seedlings is automatically put into a paused state, so it is certain that the mat seedlings A will not be damaged or that excessive force will be applied to the vertical feeding device 13. This will be prevented.

Further, when no seedling is placed on the seedling stopper 17, the belt tension 18 is displaced to the brown position due to its own weight, and the seedling stopper 17 is in an inclined state of A2.

In this case, the clutch of the seedling intermittent vertical feeding device 13 is in a disengaged state, but when the mat seedling A moves onto the seedling stopper 17, the seedling stopper 17 rotates downward to the position A3 by the weight of the mat seedling A. Therefore, the belt tension 18 is a
The tension rollers 18a press the flat belt 16 in the tensioning direction.

For this reason, the clutch of the intermittent vertical seedling feeding device 13 is left alone, and normal seedling planting work continues.

In short, the present invention provides a multi-row rice transplanter in which each seedling stopper and a corresponding seedling stopper are provided for each seedling table for storing and placing mat seedlings. The intermittent vertical feeding devices for seedlings are connected to each other in an interlocking manner so that the corresponding intermittent vertical feeding device for seedlings is switched to a non-operating state or an operating state in response to a switching operation of the seedling stopper to activate or deactivate the seedling stopper. Therefore, when using the seedling stopper, the drive of the intermittent vertical feeder for seedlings corresponding to the seedling stopper can be automatically switched to the dormant state at the same time as the operation of the seedling stopper. In order to reduce the number of planting rows, even if a seedling stopper is applied to some of the multiple seedling stands, it is possible to reliably prevent damage to the seedlings and prevent excessive force from being applied to the intermittent vertical feeder for seedlings. This has the effect of being able to maintain the vertical feeding action in an appropriate state over a long period of time.
