Description

[Detailed description of the invention] This invention relates to a vertical feed stopper for seedling mats in a rice transplanter.

Generally, when planting with a rice transplanter, the work is started from one ridge and then transferred to the other ridge in order while moving back and forth, but in the final process, the number of rows of the rice transplanter and the remaining rows are determined. If the number is different, it is necessary to adjust the number of seedling pine supply rows in the step before the final step to match the remaining number of rows.

Conventionally, a stopper rod is placed horizontally between the vertical ribs of the seedling stand, and this supports the lower end of the seedling mat to stop the vertical feeding of the seedling mat. In some cases, the attachment and detachment becomes complicated, and the workability cannot be improved.

This proposal has been made in view of the above-mentioned drawbacks, and is a vertical feeding stopper for seedling mats, which is designed to allow the stopper to be easily and reliably set when the vertical feeding of seedling mats is stopped by a simple operation. We aim to provide the following.

This proposal is a rice transplanter in which a seedling mat mounting table 35 has a plurality of rows of seedling mat mounting table 35 separated by vertical ribs 34, 34 on the surface of the seedling table 3. The strip plate 37, which is urged into a rolled-up state by an elastic force, is stored in the rib 34 in a manner that it can be freely drawn out.
The pull-out state of the strip plate 37, which houses the pull wire 38 for pulling out the strip plate 37 connected to the winding end of the pine tree and stops the vertical feeding of the pine seedlings, is determined by the claws of each mounting table 35. This relates to a vertical feeding stopper for a seedling mat that is arranged to cross over or below the placing table 35 above or below the vehicle 16.A will be explained below based on the embodiment shown in the drawings. The figure shows an aircraft in which an engine 1 is mounted on the front of the aircraft, a transmission 2 is installed at the rear of the engine 1, and wheels 4, 4, which are pivotally supported at the tips of swing arms 3, are mounted on the aircraft.

At the end of the movement of the seedling platform 8, the actuating arm 19 provided on the clutch 18 comes into contact with the vertical feed cams 20, 20 provided on both end extensions of the horizontal feed screw 12, and the rotation of the cam 20 at this time Due to the rotation of the operating arm 19, the pawl shaft 17 rotates via the clutch 18, and the pawl wheels 16, 16 provided thereon rotate.
...is something that rotates.

In this case, when the contact between the vertical feed cam 20 and the operating arm 19 is released, the operating arm 19 is rotated in the opposite direction by the spring 21 and supported by the stopper 22, and this state is maintained by the tensile force of the spring 21. .

In addition, the planting device 10 includes a planting shaft 23 provided on the side frame 11, a crank arm 24 provided on the planting shaft 23, and a swinging arm 26 pivotally supported on a bracket 25 provided on the side frame 11. The base end of the planting arm 27 is rotatably connected to the movable arm 26, and the middle of the planting arm 27 is rotatably connected to the tip of the crank arm 24, and the base end of the planting arm 27 is rotatably connected to the tip of the crank arm 24. The provided planting claw 28' is rotated on a trajectory l shown in FIG. 3 in conjunction with the rotation of the planting shaft 23.

The seedling stand 8 has rails 29 at the lower end and middle part of the back.
30 is horizontally installed, the lower end rail 29 is slidably fitted to the protruding horizontal strip 32 formed on the rear end of the seedling take-out plate 31 via a shoe, and the middle rail 30 is installed vertically on the machine. The seedling support arm 33 is slidably fitted to the upper end of the support arm 33 via a shoe and is supported in a state of low front and high back.The surface of the seedling support arm 8 is provided with vertical ribs 34 protruding from both ends and in the middle. There are four seedling mat mounting tables 35 separated by 34, and seedling mats M are placed on each of the four rows of seedling mat mounting tables 35.

A vertical feed stopper S for the seedling mat M is provided for each of the mounting tables 35.

The stopper S has a transverse groove 36 installed horizontally in a direction perpendicular to the vertical feeding direction (direction of arrow a) of the pine seedlings M at an upper or lower position close to the ratchet wheel 16, and an upright vertical groove within the transverse groove 36. A band plate 37 made of an elastic body that slides in the installed state, and the band plate 37
A pulling wire 38 serves as a sliding means.

The transverse groove 36 is a thick wall portion 3 protruding from the lower surface of the mounting table 35.
9 is cut out from the surface of the mounting table 35, and an insertion space 40 for the pulling wire 38 is formed in the inside thereof.

The strip plate 37 is formed of spring steel, is wound and supported with one end attached to a fixing pin 41 suspended from the clay wall of one of the vertical ribs 34, and is rotated in the winding direction due to the elasticity of the spring steel. energized.

Further, the cross-sectional shape of the band plate 37 is such that the upper extension part is slightly curved while the lower part is fitted into the transverse groove 36, and the curved concave surface is used as the stopper surface 37' of the seedling pine M. ing.

Then, a traction wire 38 is wound around a direction changing roll 42 that is pivotally supported within the other vertical rib 34, and one end of the traction wire 38 is inserted through the insertion space 40 and connected to the winding end of the strip plate 37. The other end is connected to a traction lever 43 slidably supported by the vertical rib 34.

The traction lever 43 has a grip portion 46 at the upper end of a sliding rod 45 that passes through a vertically long through hole 44 formed in the upper wall of the vertical rib 34, and is pulled by the lower end of the sliding rod 45 inside the vertical rib 34. The other end of the wire 38 is connected, and a side hole serving as a locking groove 44' is formed at the upper end of the vertically elongated cut-through hole.

It should be noted that the reference numeral 46 in the figure is a cut hole formed in the inner wall of one of the vertical ribs 34 at the end of the transverse groove 36.

Therefore, when performing the planting work, after placing the pine seedlings M on each mounting table 35, the pine seedlings M are placed on each mounting table 35, and then the seedling pine M is placed on each mounting table 35, and then the seedling pine M is placed on each mounting table 35, and then the seedling pine is planted using the planting claws 28 of the planting device 10 while the machine is traveling by the wheels 4, 4. }The lower end of the seedling mat M is cut and planted. In this case, the seedling mat M is slid down on the mounting table 35 by the vertical feed device 9 which is linked to the lateral feed device 7 every stroke of the lateral feed device 7. It is sent vertically.

When it becomes necessary to adjust the number of planting rows at the edge of a field, etc., the vertical feed stopper S stops the supply of pine seedlings M in unnecessary areas.

To stop the vertical feeding of this pine seedling M
When the traction lever 43 is slid upward (in the direction of arrow b) by grasping the grip part 46 in this state, the strip plate 37 connected to the traction wire 38 is pulled up by the spring steel. It is gradually unwound from the winding end against the biasing force and is pulled out from the notch hole 46 into the transverse groove 36 and crosses the mounting table 35.

Then, the traction lever 43 is engaged with the locking groove foot, and the strip plate 3 is
7 is maintained in the transverse state, the lower end of the seedling mat M is supported by the stopper surface 37' of the strip plate 37, and the vertical feeding of the mat M is stopped. If the cross is made at a position above 16, the 7th
As shown in FIG. The lower end of M is placed on the upper side of the band plate 37 to prevent interference with the ratchet wheel 16.

Next, when feeding the pine seedlings (with vertical feeding stopped) again, when the traction lever 43 is released from the locking groove 45 from the state shown in FIG. As the band 37 is wound up, the band plate 37 becomes the transverse groove 36.
The seedling pine M is then retracted into the vertical rib 34 through the notch hole 46, and the support of the seedling pine M by the stopper surface 37' is released, and the seedling pine M slides down and can be vertically fed again.

Since the present invention is configured as described above, when stopping the vertical feeding of the seedling mat M in the part where planting is not required, the band plate 37 that is wound and supported is unwound and pulled out into the transverse groove 36, and the vertical feeding is stopped. When the state is released, the strip plate 37 is retracted while being wound up by the biasing force, which is different from the conventional method.
There is an advantage that the complicated attachment/detachment work using a stopper rod is not required, and the work can be easily performed.
