Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a presser for holding a seedling mat in a rice transplanter.

[0002]

2. Description of the Related Art The use position (set position) of a conventional seedling mat holder on a seedling mat and the open position away from a seedling mat are as follows.
It is regulated by the pin hole and the lever receiving notch.

[0003]

In the position regulation of the seedling mat press as described above, the weight of the seedling mat press is concentrated on the pins and the like, the surface pressure is high, and the pins are easily deformed. Also, if there is play between the pin and the pin hole, abnormal noise is generated due to the vibration of the rice transplanter. In addition, setting the pin in the pin hole at the position of use is complicated because it is necessary to visually confirm the pin so as to enter the pin hole. Therefore, the purpose of the present invention is to obviate the need to visually check the set position of the seedling mat retainer, and to provide an accurate and easy operation of the seedling mat retainer.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above objects, the present invention provides the following seedling mat presser. That is, a stopper is provided on a bearing member that rotatably supports the support shaft of the seedling mat retainer, and a contact member is provided on which the stopper abuts, so that the bearing member, the stopper, and the contact member are integrally formed. A seedling mat press in a rice transplanter characterized by being configured to be vertically adjustable.

[0005]

[Function] The stopper for regulating the setting position of the seedling mat retainer does not lower the seedling mat retainer below the use position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments shown in the drawings will be described below.
In FIG. 1, (1) is a column fixed to the seedling table vertical ribs (2), and a shaft cylinder (3) is slidably fitted on the column.
It can be fixed with bolts (4). Further, a bearing member (6) is fixed to a support member (5) fixed to the barrel (3), and a connecting rod (8) of a seedling mat presser (7) is fixed to the bearing member (6).
The support shaft (9) is fitted so as to rotatably support the support shaft (9), and as shown in FIG. 2, the counterbore (10) of the support shaft (9) is bolted (11). It can be stopped by pushing. The bearing (6) shown in FIG.
2) is provided so that the seedling mat retainer (7) hits the stopper (12) so that it does not drop below the use position. Note that the stopper (12) shown in FIGS. 2 and 3 has a support shaft (9) of the seedling mat press (7).
The contact member (16) provided in the contact is provided. The counterbore (10) of the support shaft (9) may be flat or triangular in cross section.

FIGS. 3 and 4 show a detent groove (13) provided on a support shaft (9) corresponding to a setting position and an open position of a seedling mat retainer (7), respectively. The inserted steel ball (15) can be fitted. Also, (17) in the figure is a sub-seedling mat presser,
Numeral (19) is a leaf holder, which is attached to the column (18).

Since the present invention is constructed as described above, when the bolt (4) is loosened, the barrel (3) can move up and down on the support (1), and the bearing member (6), the stopper (12), The member (16) can be vertically adjusted integrally, so that the seedling mat press (7) can be vertically adjusted. Therefore, the height of the seedling mat holder (7) can be adjusted by tightening the bolt (4) at an appropriate position. Also, bolt (11)
When the nut is loosened, the bolt (11) separates from the counterbore (10) of the support shaft (9), so that the seedling mat press (7) can be freely rotated to take the open position. Then, when fixing the seedling mat presser (7) from the open position to the set position,
The seedling mat retainer (7) can be prevented from hitting the stopper (12) and lowering below the use position (set position). At the use position, tighten the bolt (11) to counter-sink the support shaft (9). (10) can be stopped by pushing with bolts (11).

According to FIGS. 3 and 4, since the detent groove (13) is provided on the support shaft (9) corresponding to the set position and the release position, the seedling mat press (7) is rotated. At this position, the seedling mat holder (7) can be fixed with one touch. In any case, the means for fixing the seedling mat retainer (7) can take any means.

[0010]

According to the present invention, since the setting position of the seedling mat press is regulated by the stopper, it is not necessary to visually confirm the setting position of the seedling mat press, and the operation is accurate and easy. In addition, the weight of the seedling mat holder can be received by the stopper, and concentrated stress on the positioning member, which tends to be small due to layout design, can be avoided. The type of the seedling mat (thickness, etc.) can be used to adjust the seedling mat press up and down, so that the seedling mat press can always be positioned at the best position with respect to the seedling mat. Even if the seedling mat press is adjusted up and down, the weight of the seedling mat press can always be received by the stopper.
