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.

Place pre seedling stage for placing accommodating a seedling into multiple stages, it is desirable that for seedlings supply to aft body of the seedling planting apparatus is located near the driver's seat, also preliminary seedling platform from rib In order to supply seedlings, it is desirable that the reserve seedling stand 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).

  The above-mentioned reserve seedling storage structure can be conveniently used for supplying seedlings from the cocoon to the reserve seedling platform, but it is still not suitable for supplying seedlings to an empty seedling platform before starting the planting operation. Inconvenience remained. That is, when a seedling is loaded into 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 accommodated in the reserve seedling table is eight. Therefore, it is not possible to fully load the seedling platform by supplying the seedling once to the reserve seedling platform, and the spare seedling platform is switched forward once again to swing and receive the seedling. It was necessary to move, and in order to load the seedlings on the empty seedling table, the preliminary seedling table was moved 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.

1st invention is the preliminary seedling accommodation structure of the rice transplanter which arranged the reserve seedling stand which mounts and stores a seedling in multiple stages in the front part of a riding traveling machine body,
Of the plurality of seedling receivers mounted on the reserve seedling platform, the uppermost seedling receiver is in a seedling receiving state where the seedling is placed and supported, and the seedling receiving position with respect to the seedling receiver located below A plurality of seedling receivers positioned below the uppermost stage, the first form arranged in a plurality of upper and lower stages, and the seedling receivers arranged in series in the front-rear direction. The seedling receiving form is configured to be switchable to the second form extending to the top.

  According to the above configuration, at the beginning of the planting operation, the riding traveling machine body that has entered the field is brought to the position where the front end of the body is as close to the ridge as possible. Next, the uppermost seedling receiver on the reserve seedling platform is switched to the retracted state to widely open the upper portion of the preliminary seedling platform, and a plurality of seedling receptacles arranged below it are arranged in series in the front-rear direction. Switch to the second configuration extending forward of the aircraft. The cocoon worker feeds the seedlings from the front of the seedling receptacles arranged in series in the front and rear, and pushes them back in order in a column. The driving operator who is on the passenger traveling body sequentially takes out the seedlings that have reached the last seedling receiving body and supplies them to the rear seedling platform.

  In this case, when a plurality of seedling receivers are arranged in series in the front-rear direction and switched to the second form, the uppermost seedling receiver located above the seedling receiver is retracted from the seedling receiving position, and the upper part of the preliminary seedling rest is widely opened. Therefore, the operation for switching the shape of the lower seedling receptacle can be performed without the uppermost seedling receptacle becoming an obstacle.

  When seedlings are fully loaded on the seedling platform of the seedling planting device, the uppermost seedling receiver is returned to the seedling receiving state, and the lower seedling receiver is returned to the first form and the seedlings are stacked and accommodated. The spare seedling is placed on each seedling receiver, or the uppermost seedling receiver is returned to the seedling receiving state to place the spare seedling, and the lower seedling receiver is placed on the second seedling receiver. It moves to a planting operation in a state where spare seedlings are placed in front and rear columns in the form.

  When the seedling seedlings are consumed in association with the planting operation, the operator takes out the seedlings from the spare seedling platform and supplies them to the seedling platform. When there are no or fewer seedlings on the reserve seedling platform, the next seedling is supplied from the basket to the reserve seedling platform when approaching the cocoon for turning the aircraft.

  Therefore, according to the first aspect of the present invention, by switching the preliminary seedling platform except the uppermost stage to the second configuration, the seedling can be supplied from the straw to the preliminary seedling platform, and the seedling on the rear of the aircraft can be placed from the preliminary seedling platform. It became possible to easily supply seedlings to the table. In addition, since the top seedling receiver can be switched to the retracted state and the upper part of the reserve seedling table can be opened widely, the shape of the seedling receiver can be easily switched in a wide space, and handling is also easy. It will be excellent.

According to a second invention, in the first invention,
The uppermost seedling receiving body is configured to stand up and swing upward with respect to the seedling receiving body positioned below to switch to the retracted state.

  According to the above configuration, the operation of switching the uppermost seedling receiving body between the seedling receiving action state and the retracted state becomes easy and easy.

According to a third invention, in the first or second invention,
The preliminary seedling mount is equipped with four stages of seedling receivers, and among the three stages of seedling receivers excluding the uppermost stage, the upper and lower seedling receivers are fixedly arranged before and after the middle stage seedling receivers. They are arranged side by side in the second form.

  According to the above configuration, in the second form in which three seedling receivers are arranged in series in the front-rear direction, the foremost seedling receiver protrudes forward from the front end of the machine body, and the seedling supply from the cocoon is easy. Become. The last seedling receiver is extended to the vicinity of the driver's seat, so that the driver can easily take out the supplied seedling and supply it to the seedling table.

According to a fourth invention, in the third invention,
The upper seedling receiver is inverted and swung to switch the seedling receiving form, and the lower seedling receiving body is detached to switch the seedling receiving form.

  According to the above configuration, by setting the swing fulcrum of the upper seedling receiver above the end of the middle seedling receiver, the upper seedling receiver is inverted and swung to the end of the middle seedling receiver. It is possible to butt-connect, and the load acting on the upper seedling receptacle can be received and supported by the end of the middle seedling receptacle, so that the posture of the inverted upper seedling receptacle can be easily and reliably maintained. The lower seedling receptacle can be switched to the second configuration by engaging and connecting to the end of the middle seedling receptacle.

A fifth invention is the fourth invention, wherein:
The middle seedling receiver is connected and fixed to the upright and fixed support, and the upper seedling receiver is supported by the middle seedling receiver so as to be able to reversely swing.

  According to the above configuration, since the upper seedling receiving body in the state of receiving seedlings is supported by the long middle seedling receiving body before and after being fixed, the upper seedling receiving body is long in the front-rear direction or has a large span in the front-rear direction. It can be received and supported stably and reliably.

As shown in FIGS. 8 and 10, support frames 30 bent in an arch shape are erected on the left and right of the middle seedling receiver 27 (m), and a fulcrum bracket 31 protruding from the front end portion of the support frame 30. And the connection fitting 32 protruding downward from the front left and right of the upper seedling receiving body 27 (u) is pivotally connected so as to be swingable around the lateral fulcrum a. Usually, the upper seedling receiving body 27 (u) is swung up above the middle seedling receiving body 27 (m), and is received and supported by the left and right support frames 30 via a group of rollers 28. In this case, the upper part of the support frame 30 is bent inward, and the side frame 27a of the seedling receiver 27 (u) straddles the upper part of the left and right support frames 30, so that the seedling receiver 27 (u) has a horizontal direction. Is positioned.

  As shown in FIG. 9, the upper seedling receiver 27 (u) is swung forward by 180 ° around the fulcrum a, so that the upper seedling receiver 27 (m) is placed at the forward end of the middle seedling receiver 27 (m). The rearward end of the body 27 (u) comes into contact, and the upper seedling receiver 27 (u) is connected to the front end of the middle seedling receiver 27 (m) (second form). In this case, the front end of the middle seedling receiver 27 (m) is inserted between the left and right guides 27e provided at the rear end of the upper seedling receiver 27 (u), and the upper seedling receiver 27 (m) is inserted. The lateral displacement of the body 27 (u) is prevented.

As shown in FIG. 11, the lower part of the seedling receiving body 27 (d) is desorption freely inserted connected to a pair of support brackets 33 back and forth provided in the lower part of the strut 25. The support fitting 33 is provided with a tongue piece 33a upward, and an insertion connecting portion 34 for inserting the tongue piece 33a from below is integrally formed on the outside of the side frame 27a of the seedling receiver 27 (d). The seedling receiver 27 (d) can be inserted and connected to the support bracket 33 from above to be disposed below the middle seedling receiver 27 (m).

  A pair of left and right connecting fittings 35 project upward from the rear part of the middle seedling receiving body 27 (m), and a pair of left and right coupling fittings 36 project upward from the front part of the lower seedling receiving body 27 (d). It is installed. A connecting pin 37 protrudes outward from the fuselage 35 on the outer side of the fuselage, and a connecting pin 38 protrudes toward the fuselage 36 on the inner side of the fuselage 36 inside the fuselage.

  Thus, the reserve seedling base 8 configured so that the seedling receiving form can be switched 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 base 8 is swung up and swung to be switched to the retracted state, and the lower three-stage seedling receiving bodies 27 are arranged in series in the front-rear direction and extended forward of the machine body. Switch to the second form.

  The cocoon worker supplies seedlings from the front part of the seedling receiving body 27 arranged in series in the front-rear direction, and sequentially pushes them backwards in a column. The driving operator who is on board the passenger traveling body 3 sequentially takes out the seedlings that have reached the last seedling receiving body 27 and supplies them to the seedling setting table 15 at the rear of the body. The seedlings are handled in a state where they are put in a seedling box (not shown) or removed from the seedling box and placed on a seedling scoop plate (not shown).

  When the seedling platform 15 is fully loaded with seedlings, the seedling receiving body 27 is returned to the first form of the upper and lower stacks, and the seedlings are stacked and placed in the second form, or the seedlings are arranged in the front and rear columns in the second form. Move to the planting work in the mounted state. 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. However, in a paddy field where it is difficult to bring the passenger traveling body 3 close enough to the ridge, it is preferable to perform the planting operation by setting the reserve seedling stand 8 in the second form.

  When the seedlings on the seedling table 15 are consumed during the planting operation, the operator takes out the seedlings placed on the preliminary seedling table 8 and supplies them to the seedling table 15. When there are no seedlings on the reserve seedling table 8 or the remaining seedlings are low, the seedlings are supplied from the basket to the preliminary seedling table 8 when the next seedling is approached to change the aircraft direction.

  The upper ends of the vertical ribs 27b in each seedling receiver 27 are formed higher than the upper ends of the horizontal ribs 27c, and the rollers 28 are provided so as to protrude slightly from the vertical ribs 27b. When the seedling is pushed and moved along the arranged seedling receptacle 27, the seedling (nursery seedling box) can be smoothly fed forward without being caught by the lateral rib 27c.

  In the second embodiment, the seedling receivers 27 arranged in series in the front-rear direction are inclined downward by several degrees as a whole so that the seedling supplied from the cocoon can be moved rearward smoothly.

  A stopper 40 formed by bending a round bar is inserted and connected across the left and right side frames 27a on the left and right of the front and rear end portions of the lower three-stage seedling receiver 27. As shown in FIG. 14, the stopper 40 is switched between a standing posture projecting upward from the seedling receiving surface and a lying storage posture immersing from the seedling receiving surface as indicated by a virtual line in FIG. It is supported so that it can swing. Both ends of the stopper 40 are inserted into and supported by the support holes 41 formed in the side frame 27a, and the bent locking portions 40a are inserted into the longitudinal elongated holes 42 formed in the side frame 27a. Thus, the stopper 40 is elastically deformed and the locking portion 40a is removed from the elongated hole 42, so that the stopper 40 can be swung into the lying down storage posture. The stopper 40 in the fallen storage posture is held in a posture that is recessed from the seedling receiving surface by being engaged in a recess 43 formed in a cutout in the vertical rib 27b. In addition, even if the seedling receiving part 40b bent and formed on the left and right sides of the stopper 40 is bent and formed in a shape in which the top is located near both ends thereof, even if the seedling is placed on the seedling receiving part 40b and a load is applied to the top. The locking portion 40a is not easily retracted and prevents the stopper 40 from falling on its own even if the seedling is inadvertently placed on the seedling receiving portion 40b.

In the first embodiment in which the seedlings are stacked and stacked, the stopper 40 is protruded above the seedling receiving surface for each seedling receiving body 27 so that the stopper 40 receives and prevents the mounted seedlings from sliding back and forth. . In the second embodiment in which the seedlings are moved in tandem in the longitudinal direction, the front and rear stoppers 40 in the seedling receiving body 27 (m) that hinder the forward and backward movement of the seedlings are switched to the lying down storage posture. Note that the rear stopper 40 in the seedling receiver 27 (d) is left in an upright state to prevent the seedling that has moved rearward from falling inadvertently. The stopper 38 of the upper seedling receiving body 27 (u) that is turned upside down faces downward, so there is no need to lie down.
