Description

  The present invention relates to a preliminary seedling storage structure for a rice transplanter in which a preliminary seedling platform for mounting and storing seedlings in a plurality of stages is provided at the front of a passenger traveling machine body.

It is desirable that the reserve seedling table on which the seedlings are placed and accommodated in multiple stages is located close to the driver's seat for supplying seedlings to the seedling planting device at the rear of the aircraft. In order to supply seedlings to the platform, it is desirable that the reserve seedling platform protrudes forward of the aircraft. In order to satisfy this, a structure has been developed in which the support seedling support column has a quadruple link structure and can swing back and forth (see, for example, Patent Document 1).
JP 2004-113071 A

  The above-mentioned reserve seedling storage structure can be conveniently used to supply seedlings from the cocoon to the reserve seedling platform, but for the work of supplying seedlings to the empty seedling platform before starting the planting operation Inconvenience still remained. That is, when a seedling is supplied to an empty seedling setting table, first, the preliminary seedling setting table is moved forward, and the seedling is supplied from the basket here. Next, the preliminary seedling platform is moved backward, the seedlings stored in the preliminary seedling platform are taken out and supplied to the seedling platform.

  In recent years, the seedling platform of the rice transplanter has two seedlings (mat seedlings) per line, such as increasing the overall length to increase the number of seedlings mounted, or mounting an extended seedling resting plate. Many are configured to be placed in tandem. For example, in an 8-row planting rice transplanter, 16 seedlings can be initially placed on a seedling table. However, in the case of an 8-row rice transplanter, considering the strength of the reserve seedling stand, the weight balance and stability of the fuselage, etc., it is possible to equip the left and right sides of the front of the fuselage with a four-tiered reserve seedling stand. In many cases, the number of seedlings that can be placed on the reserve seedling table is eight. Therefore, it is not possible to fill the seedling stage with a single seedling supply to the reserve seedling stage, but the spare seedling stage is moved forward again to receive the seedling supply and then moved backward again. In order to load the seedlings in the empty seedling table, it was necessary to move the preliminary seedling table back and forth twice, which was a troublesome work.

  The present invention has been made paying attention to such points, and it is easy to supply seedlings from the pods to the reserve seedling platform and to supply the seedlings from the reserve seedling platform to the rear seedling platform. The main purpose is to provide a reserve seedling storage structure that can be used in the future.

It is configured so that it cannot be done.

  In the second embodiment in which the upper seedling receiver 26 (u) and the lower seedling receiver 26 (d) are connected in series to the front and rear ends of the middle seedling receiver 26 (m) as described above, As shown in FIG. 3, the upper seedling receiving body 26 (u) is supported in contact with the middle seedling receiving body 26 (m) in a slanted front posture and the lower seedling receiving body 26 (d). Is supported in contact with the middle seedling receiving body 26 (m) in a slightly inclined posture.

Thus, the reserve seedling stand 8 configured so that the seedling receiving form can be switched between the stacked first form and the front and rear series second form is used as follows, for example.
At the beginning of the planting operation, the passenger traveling machine body 3 that has entered the field is brought to the position where the front end of the machine body is as close to the ridge as possible. Next, the uppermost seedling receiving body 26 in the preliminary seedling setting table 8 is swung upward to be switched to the retracted state, and the lower three stage seedling receiving bodies 26 (u), (m), (d) are held. It switches to the 2nd form arranged in front and back in series and extended ahead of the body.

  The cocoon worker supplies the seedling F from the front part of the seedling receptacles 26 (u), (m), and (d) arranged in series in the front-rear direction, and sequentially pushes them backwards in a column. The driver who is on board the riding traveling machine body 3 sequentially takes out the seedlings F that have reached the last seedling receiving body 26 (d) and supplies them to the seedling platform 15 at the rear of the machine body. In addition, the seedling F is handled in a state where it is in the nursery box or is taken out from the nursery box and placed on the seedling scooping plate.

  When the seedling F is fully loaded on the seedling table 15, the seedling receivers 26 (u), (m), (d) are returned to the first form of the upper and lower stacks, and the seedlings F are stacked and loaded. Or it moves to a planting operation in the state where the seedlings F are placed in the front-rear tandem with the second form. In this case, in the paddy field where the cocoon is low and the front end of the passenger traveling body 3 can be approached until it overlaps with the cocoon, the seedling stand 8 is a seedling from the paddle to the spare seedling base 8 even in the first form. Although it is possible to easily supply F, in a paddy field where it is difficult to bring the passenger traveling body 3 sufficiently close to the ridge, it is preferable to perform the planting operation with the reserve seedling stand 8 in the second form.

  When the seedling F on the seedling stage 15 is consumed in association with the planting operation, the driving operator takes out the seedling F placed on the preliminary seedling stage 8 and supplies it to the seedling stage 15. When the seedling F on the reserve seedling base 8 is lost or the remaining seedling F is low, the seedling F is supplied from the straw to the preliminary seedling support base 8 when it approaches the cocoon to change the direction of the aircraft.

  The upper ends of the vertical ribs 26b in each seedling receiver 26 are formed so as to be positioned higher than the upper ends of the horizontal ribs 26c, and the rollers 28 are provided so as to protrude slightly from the vertical ribs 26b. When the seedling F is pushed and moved along the arranged seedling receptacles 26, the seedling F (nurturing box) can be smoothly fed forward without being caught by the lateral rib 26c.

  The four-stage seedling receiver 26 is supported in a posture that is slightly inclined downwardly with respect to the support 25, and the lower three-stage seedling receivers 26 (u), (m), (d) In the state switched to the two configurations, the seedling receivers 26 (u) and (d) connected to the front and rear of the middle seedling receiver 26 (m) are connected in a refraction posture in which the free end side is slightly raised. Thus, the entire seedling receiving surfaces of the seedling receiving bodies 26 (u), (m), and (d) are curved downwardly in a side view. The front / rear weight balance of the whole rice transplanter is slightly rearward, and the whole body is slightly rearwardly inclined in the field, so in the seedling receivers 26 (u), (m), (d) of the second form On the seedling receiving surface, the last seedling receiving body 26 (d) is in a substantially horizontal or slightly rearward inclined posture, and the seedling receiving bodies 26 (u) and (m) in front of the seedling receiving body 26 (d) are inclined downwardly toward the front. The seedling F supplied from the cocoon can be smoothly moved rearward.

  A stopper 43 formed by bending a round bar is attached and fixed to the front end of the upper seedling receiver 26 (u) and the rear end of the lower seedling receiver 26 (d). At the front and rear ends of the left and right side frames 27a, the rear end of the upper seedling receiver 26 (u), and the front end of the lower seedling receiver 26 (d), A movable stopper 44 formed by bending a round bar into a U shape is inserted and supported so as to be slidable and rotatable. As shown in FIG. 8, the movable stopper 44 is slid outwardly by a spring 45 fitted on the outside, and the tip of the folded portion 44a is inserted into an upper locking hole 46 formed in the side frame 27a. By engaging, the working posture is maintained to protrude upward from the seedling receiving surface, and the tip of the folded portion 44a is engaged with the lower locking recess 47 formed in the side frame 27a or folded and rotated. Thus, the retracted posture is retracted from the seedling receiving surface.

  In the first embodiment in which seedlings are stacked and stacked, the movable stopper 44 is protruded above the seedling receiving surface for each seedling receiving body 26, so that the seedling F placed and stored slides back and forth. The stopper 44 receives and prevents it. In the second embodiment in which the seedlings F are moved in tandem in the longitudinal direction, the front and rear movable stoppers 44 in the seedling receiver 27 (m) that hinder the movement of the seedlings F, the rear in the foremost seedling receiver 27 (u) The movable stopper 44 and the movable stopper 44 in front of the rearmost receiving body 27 (d) are switched to the retracted posture.

  A support rod 48 is pivotally connected to the upper part of the support on the front side of the machine body. The support rod 48 is held in a posture along the support column 25 via the spring clamp 49 in the stacked first form, and in the second form arranged in series in the front-rear direction, the foremost seed receiver The lower end portion of the support rod 48 swinging forward is locked and connected to the connection hole 32 of the front connection fitting 31 in the body 26 (u), and the seedling receiving body 26 (u) that has become empty is moved by the movement of the body. Inadvertently moving up and down is prevented. Although the last seedling receiver 26 (d) may be regulated in the same manner as described above, when the operator gets on and off from the side of the aircraft, the seedling receiver 26 (d) is lifted and shaken upward. Since the seedling receiving body 26 (d) at the rearmost part in the second form is not connected and supported by the support rod 48, it is rather convenient to use.

  [Other Examples]

  (1) As shown in FIG. 17, a support pin 50 is connected and fixed to the outside of a connecting metal fitting 35 (p) with a pin, and a hook-shaped clamp metal fitting 51 made of a spring plate material is freely rotatable on the supporting pin 50. In the second embodiment, the free end portion of the clamp fitting 51 is elastically engaged with the connection pin 38, so that the connection fitting 37 with a hole is formed by the connection fitting 35 (p) with the pin and the clamp fitting 51. (h) may be sandwiched from the left and right to prevent the seedling receiving body 26 (d) to be detached from moving laterally. According to this, even if the seedling receiving body 26 (d) is swung up unexpectedly and the engagement between the locking projection 40a and the locking piece 42 is released, the seedling receiving body 26 (d) moves laterally. Can be prevented. When removing the seedling receiver 26 (d), the clamp fitting 51 is removed from the connecting pin 38, and then the seedling receiver 26 (d) is swung upward and moved laterally.
