Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower end structure of a seedling table of a rice transplanter.

[0002]

2. Description of the Related Art Conventionally, there is a seedling table of a rice transplanter in which a lower end portion of the seedling table is kept at a constant distance from a rising surface of a seedling take-out plate.

[0003]

The front end of the seedling mat on the seedling placing table is placed on the bottom receiving surface of the seedling take-out plate, and when the seedling planting work is performed in such a state, the seedling mat is placed on the seedling placing plate. It will slide sideways with the table and rub against the bottom receiving surface of the fixed seedling pick-up plate, and the friction resistance will cause the lower surface of the front end of the seedling mat to resist the bottom receiving surface of the seedling pick-up plate so that the seedling mount will not slide smoothly. When the seedling mat slides in the sideways sliding direction, it wins, and then when the seedling table slides in the opposite direction, only the seedling mat slides in the opposite direction and the seedling mat becomes the opposite direction. Since it did not move, there was a risk of stockouts.

It consists of a seedling take-out plate (9) with a substantially L-shaped cross section as a guide rail provided at the lower end of (8), and a planting claw (10) provided at the front of the lower end of the seedling placing table (8). (11) is a planted arm, (12) is a driven arm, (13) is a driven arm support, and (14) is a crank arm.

The seedling mounting table (8) is provided with vertical ribs (15) protruding for each width of the seedling mat so that a number of seedling mats (M) corresponding to the number of planting rows can be mounted. The lower end of (15) extends to a position near the rising surface (9-1) of the seedling picking plate (9), and the seedling mounting plate (16) located between each vertical rib (15) is the lower end. When the seedling mat (M) is placed on the seedling placing plate (16) by making the seedling shorter than the lower end of the vertical rib (15), the front end part of the seedling mat (M) has the vertical rib (15). The seedling plate (16), which is shorter than the lower end, extends beyond the lowermost edge.

Therefore, when the planting claw (10) is rotated to perform the planting operation, it is provided on the rising surface (9-1) and the bottom receiving surface (9-2) of the seedling take-out plate (9). Notched groove (17) to short seedling plate (16)
The seedling block (M ') is cut from the front end of the seedling mat (M) while passing the front of the lower end of the seedling, and seedlings are planted in the field.

A locking rail (18) is provided on the rear surface of the seedling placing table (8) in a protruding manner, and the rail (18) is connected to the lower end of the seedling removing plate (9) having an L-shaped cross section. The support rod (19) is configured to be supported by the support frame (19) to support the seedling placing table (8), and the seedling placing table (8) is guided by the support rod (19). And slide laterally.

A plurality of elastic strips (20) are continuously provided at a lower end edge of the seedling placing plate (16) at an extended lower position of the lower end edge at regular intervals. The tip of the strip (20) has a vertical rib (1
It extends to the same position as the lower end of 5). The elastic strip (20) and the seedling mounting plate (16) are substantially flush with each other.

Further, when the elastic strip (20) is made of rubber or the like, as shown in FIG. 2, it is provided as a narrow strip with a narrower width than the cutout groove (17) so as to project. Alternatively, as shown in FIG. 3, the width of the strip is formed to be slightly narrower than the width of the nail of the planting nail (10), and the interval between the strips is almost equal to the nail of the planting nail (10). Seedling block cut by the planting claws (10) by setting the width

In some cases, the resistance of 0) is evenly applied to the lower surface of the seedling block.

In the figure, (L) indicates the nail width of the planting nail (10),
(l) shows the width of the elastic strip (20).

The embodiment of the present invention is configured as described above, and the seedlings are planted while holding the machine body (a) on the surface of the field through the float while traveling on the cultivator by the wheel (3). The seedling block (M ') is planted by the attachment part (B), and the planting claw (10) cuts the seedling mat (M) on the seedling plate (16) into the notch of the seedling take-out plate (9). Cutting from the groove (17) and planting as a seedling block (M '), the front end of the seedling mat (M) is a seedling plate (16).
Elastic strips that are continuously extended from the lower end (16-1) of the
Being supported by (20), therefore seedling mat
Since the back surface of the front end of (M) does not directly contact the bottom receiving surface (9-2) of the seedling take-out plate (9), the elastic strip (20) is interposed between them. The back surface of the front end of the seedling mat (M) may contact the bottom receiving surface (9-2) of the seedling take-out plate (9) and rub against it even when the seedling mounting table (8) slides laterally or vertically. ,Also,
Without being caught, the seedling mat (M) also moves accurately in response to the lateral sliding of the seedling mounting table (8), and when the seedling mounting table (8) moves to the lateral sliding in the opposite direction, the stock is out of stock. The planting claws (10) are especially suitable for the seedling take-out plate.
If the seedling block (M ') is cut through the notch groove (17) in (9) and is rotated below the elastic strip (20), the elastic strip is used.

Since the elastic strips (20) for supporting the parts are continuously provided in an extended shape, and the elastic strips (20) and the seedling placing plate (16) are substantially flush, Since the front end of the mat (M) is supported on the same elastic strip (20), the entire bottom surface of the front end of the seedling mat (M) does not come into contact with the seedling picking plate (9) and the seedling mounting plate (9) is placed. The front end of the seedling mat (M) also slides accurately in response to the lateral sliding of the platform (8), eliminating the causes such as stunting and allowing accurate seedling planting work.

When the seedling mat (M) is vertically fed downward, the lower surface of the seedling mat (M) can be smoothly fed vertically without being caught by the elastic strips (20). While maximally supporting the front end of the mat (M) and avoiding contact with the rising surface (9-1) of the seedling take-out plate (9), there is no hindrance to the lateral feeding of the seedling mounting table (8). Although the structure is simple as a whole, the planting work can be performed efficiently.

[0015]

According to the present invention, an elastic strip for supporting the front end of the seedling mat placed on the seedling mounting plate is provided with its base end connected to the lower end of the seedling mounting plate and its tip. Since the seeds are extended along the bottom receiving surface of the seedling picking plate to a position near the rising surface, the front end of the seedling mat located between the lower end of the seedling mounting plate and the rising surface of the seedling picking plate is , Can be reliably supported over the entire width of the bottom receiving surface of the seedling take-out plate,
When the seedling table is slid sideways, the rear surface of the front end portion of the seedling mat can be slid sideways without directly contacting the bottom receiving surface. Therefore, it is possible to prevent the front end portion of the seedling mat from being deformed due to frictional resistance or being caught, and it is possible to prevent the occurrence of a stock stall or the like, and it is possible to ensure a good planting work efficiency.

Moreover, the side surface of the front end portion of the seedling mat is supported by the lower ends of the vertical ribs when the seedling placing table slides laterally, and the lower ends of the vertical ribs are on the bottom receiving surface of the seedling take-out plate. Along the lower edge of the seedling placing plate along the side of the seedling placing plate, and since it extends to a position near the rising surface of the seedling removing piece, between the lower edge of the seedling placing plate and the rising surface of the seedling removing plate. The front end of the seedling mat located at can be securely supported on the bottom receiving surface over substantially the entire width, and the front end of the seedling mat can be prevented from deforming in cooperation with the elastic strip described above. Therefore, the planting work efficiency can be well secured from this point as well.

Further, even when the seedling mat is vertically fed on the seedling mounting plate, since the upper surface of the seedling mounting plate and the upper surface of the elastic strip are substantially flush with each other, the front end portion of the seedling mat is Can be smoothly transferred from the seedling mounting plate to the elastic strips for vertical feeding, and from this point also it is possible to prevent the seedling edge of the seedling mat from deforming and improve planting work efficiency. Can be secured.
