Description

[Detailed Description of the Invention] [Industrial field of application] In the present invention, seedlings are picked by the planting claws while pressing the grazing seedlings on the seedling mounting table that are laterally fed to the seedling picking side with the front picking plate side. The present invention relates to a seedling holding device for a grass transplanter that is configured as described above.

[Conventional technology]

Conventionally, a seedling table which can be reciprocated in the lateral direction is obliquely provided above a seedling taking plate having a seedling taking port, and a shutter fork capable of holding a seedling is provided above the lower tilted side of the seedling placing table. In a rush transplanter constructed by vertically movable, a horizontal row of seedlings between the shutter fork and the front standing surface of the seedling take-out plate is planted with the shutter fork moving downward to hold the seedling. It had a structure that could be scraped off and planted.

[Problems to be solved by the device]

Therefore, when the shutter fork moves upward and seedlings are fed to the seedling picking plate side, if the seedling pushing force is weak, the state in which the tip side, which was held by the shutter fork until then, is fed laterally to the seedling picking plate side is poor. As a result, there were problems such as a lack of stock, and the number of plantings was not stable because the seedlings were dragged by the planting claws around the seedling take-out port.

[Means for Solving the Problems]

The present invention solves such a problem and enables the seedling to be satisfactorily pressed so that stable planting can be performed.Therefore, a lateral reciprocating drive is performed above the seedling taking-out plate having the seedling taking-out port. In a grazing transplanter constructed by slanting the seedling placing table, and constructing a shutter fork capable of holding the seedling above and below the inclined lower side of the seedling placing table so as to be vertically driven via an arm, The fork rods are formed so that the lateral distance between them is approximately the same as the lateral feed pitch of the seedling mounting table, and the planting claws cross over the fork rods in the downward movement position and enter the upper side of the seedling mounting table. In order to scrape off the seedlings of the stock, a shutter fork is installed close to the front standing surface of the seedling take-out plate so as to be vertically driven in conjunction with the vertical feed.

[Action]

Therefore, the planting claw that enters the tip side of the rush seedling pressed by the shutter fork inwardly across the fork rod does not drag the surrounding seedlings.
Since it will be possible to stably scrape each plant portion and scrape off the seedling pressed by the shutter fork, if the shutter fork moves upward, even if the seedling pushing force is weak, the seedling ejection plate The seedlings can be sent well to the side.

〔Example〕

 Next, an embodiment shown in the drawings will be described.

FIG. 2 shows a side view of the hay transplanter, in which the transplanting device (4) can be raised and lowered via the link mechanism (8) behind the four-wheeled passenger car (B) having the handle (6), the seat (7), etc. The transplanting device (A) has a planting case (10) in which the planting claws (5) are interlockingly connected to the rear of the float (9), and the planting case (10) is installed above the float (9). A seedling pick-up plate (2) having L-shaped sides having each seedling pick-up port (1) is provided above the seedling pick-up plate (2), and can be reciprocally moved laterally above the seedling pick-up plate (2). A plurality of seedling mounts (3) are installed obliquely.

A cassette table (11) loaded with rush seedlings is removably fitted to a midway portion of each seedling table (3), and the bottom surface of the seedling table (3) and the cassette table (11) and A seedling pushing plate (14) is projectingly provided in front of the moving table (13) having each roller (12) capable of contacting both side surfaces, and the seedling placing plate is extended from both sides of the moving table (13) to both sides. At the lower part of the connecting frame (13a) extending below the bottom surface of the table (3), both rollers (12a) that can contact the bottom surface of the seedling mounting table (3) are mounted on the bottom of the connecting frame (13a).
A constant pressure spring roll (16) is erected on a bracket (15) which is hung vertically downward from the lower side of the inclination, and a spring band (16a) which is extended from the constant pressure spring roll (16) and is always elastically biased. The take-up reel (18) with a lathe that connects the tip of the to the lower part of the connecting frame (13a) and can be reversely driven by the rotating lever (17) at the upper end of the seedling stand (3).
And a wire (19) extending from the reel (18) is connected to the moving base (13).

A seedling holding plate (20) capable of holding the upper leaf stems of the rush seedlings is horizontally installed above the lower slope side of each seedling mounting table (3), and stands upright in front of the seedling removing plate (2). On a part of the surface (2a), a belt (21) which can be rotated along with the lateral movement of the seedling table (3) is stretched along the standing surface (2a).

On the support shaft (23) which is horizontally mounted on the bracket (22) on the lower side of each seedling mounting table (3), both arms (24) extending obliquely upward along both outer sides of the seedling mounting table (3) are provided. ) Is pivotally supported, and a comb-like shutter fork (4) is vertically hung from a support plate (25) installed between the ends of both arms (24) to form the support plate (25).
The tension springs (27) for elastically urging the shutter fork (4) are connected between the upper ends of both ends of the and the lower bracket (26), respectively, and are shown in FIG. As described above, the fork rods (4a) are parallel to each other so that the lateral spacing (L) of the fork rods (4a) in the shutter fork (4) is substantially the same as the lateral feed pitch of the seedling placing table (3). As shown in FIG. 1, the planting claws (5), which are arranged in parallel with each other and head toward the seedling take-out opening (1), straddle the fork rod (4a) and, as shown in FIG. The shutter fork (4) can be scraped so as to scrape off one seedling held by the fork rod (4a) while penetrating into the upper side of the seedling mounting table (3) along a predetermined range along the line (X). ) Is the front standing surface (2a) of the seedling take-out plate (2)
It will be constructed by erection so that it will move downwards close to.

In addition, at both ends of the arms (29) extending from the support shaft (28) horizontally extending below the seedling placing table (3), the arms (24) are provided.
Both rollers (30) that can contact the lower edge of the
One of the driven cams (31) fixed to the support shaft (28)
It is constructed so that it can abut against the rotating cam (32) at the end of the lateral movement of the seedling placing table (3).

Therefore, the lower end of the shutter fork (4), which is moved downward by the tension spring (27), comes into contact with the tip of the rush seedling that is being pressed by the seedling pushing plate (14) and is being fed, thereby pressing down the seedling. In the state of performing, as shown in FIG. 1 and FIG. 6, the fork rod (5) operating along the locus (X) invades inward while straddling the fork rod (4a). It is possible to stably scrape one seedling held by 4a) without dragging the surrounding seedlings, and the shutter fork is moved along with the lateral movement of the seedling mount (3). By (4), it is possible to sequentially scrape and plant one horizontal row of seedlings being pressed.

When the seedling mounting table (3) stops moving laterally, as shown by the phantom line in FIG. 5, one of the driven cams (31) abuts the rotating cam (32) and the roller (30) rotates. ) Causes the arm (24) to move upwards, pulling the tension spring (27) to move the shutter fork (4) upward, where the seedling pushing plate (14) pushes the rush seedlings. The vertical seedling is fed until the tip side is close to the upright surface (2a) of the seedling take-out plate (2), and immediately after that, the shutter fork (4) descends again to hold the seedling.

[Effect of device]

As described above, according to the present invention, the seedling placing table which laterally reciprocally drives is obliquely provided above the seedling taking plate having the seedling taking port, and the shutter capable of holding the seedling is provided above the inclined lower side of the seedling placing table. In a rush transplanter constructed by vertically moving a fork through an arm, the fork rods of the shutter fork are formed so that the lateral distance between them is substantially the same as the lateral feed pitch of the seedling table, and the planting is performed. The shutter fork is close to the front standing surface of the seedling take-out plate so that the attached claws can cross the fork rods in the lower position and enter the upper side of the seedling mounting table to scrape one seedling. The shutter fork (4) that moves up and down via the arm extends the tip of the rush that is pressed inward over the fork rod (4a). The invading planting claws (5) can accurately scrape the plants one by one without dragging the surrounding seedlings, which makes it possible to plant well with a stable number of plants. Also, since the seedling pressed by the shutter fork (4) that is vertically driven via the arm is scraped off, when the shutter fork (4) moves upward, even if the seedling pushing force is weak, Since the seedlings can be reliably and satisfactorily fed to the seedling take-out plate (2) side, the planting can be performed satisfactorily without causing the missing plant, and it has a feature that it can be suitably implemented with a simple structure.
