Description

  The present invention relates to an improvement for a container for transporting seedlings that transports seedlings prepared in a seedbed to a field to be transplanted during a rice planting operation.

  When transplanting paddy rice seedlings prepared in the nursery by rice planting in Honda, the seedlings are transported to the field by putting seedlings in seedling boxes (seedling boxes) and seeding them. Because it is in a state of being inserted into the seedling box, the entire seedling box containing the tailored seedlings is loaded onto the carrier of a truck or the like and transplanted (rice planted) by the carrier. Carry to the side of the farm next to the field where the work is to be carried out, where the seedling box is lowered from the carrier bed, the seedling is pulled out from the seedling box, and this is loaded into a rice transplanter waiting in the field. The plant is planted in the field.

  The means to load and transport the tailored seedlings together with the seedling boxes accommodated in the densely planted state on the carrier bed of the transport vehicle improves the workability of loading and unloading the seedling boxes on the carrier platform. Therefore, as shown in FIG. 1, a rectangular frame whose inner dimensions in the left and right width directions correspond to the lateral width of the seedling box 1 is assembled, and one end side of the seedling box 1 is inserted obliquely into this. Sometimes, the support rod 3 that holds the seedling box 1 in an upright posture is extended from the bottom surface of the seedling box 1 including the seedling group housed in the seedling box 1 to the tip side of the seedling. The frame A is provided in parallel with the frame body at intervals corresponding to the height dimension, and thereby, a platform A is mounted on which a large number of seedling boxes 1 are stacked in parallel and arranged in an oblique posture. As shown in FIG. 2, this platform A is loaded on the loading platform t of a transport vehicle T such as a light truck. Means to useless have been made.

  This means that a large number of seedling boxes 1 can be loaded on the platform t of the transport vehicle T at a time by loading a large number of seedling boxes 1 on the platform A. The seedling box 1 containing seedlings has a weight of about 6 kg, so that when 12 to 15 seedling boxes 1 are mounted in parallel on one base A, Since the weight is 70 to 90 kg, the work of loading this onto the loading platform t of the transport vehicle T is a work of two persons carrying two workers respectively positioned at the front and rear ends of the gantry A. So there is a problem that requires multiple workers and heavy labor.

  Moreover, the loading of the platform A onto the loading platform t of the transport vehicle T is performed by aligning the loading platform t on the loading platform t without any gap in order to increase the efficiency of transportation. It is necessary to move to every corner of t, and this movement must be performed by at least two people, and there is a problem that requires a lot of workers and heavy work labor.

  Furthermore, when it is carried on the loading platform t of the transport vehicle T to the shore next to the field where the rice planting work is performed, the platform A is lowered from the loading platform t, and the seedling box 1 is taken out. At the time of this work, it takes at least two workers to move the platform A loaded in the back of the loading platform t to the edge of the loading platform t and hold it down, There is a problem that requires labor and heavy labor.

  In addition, when carrying the seedling by the transport vehicle using the stand A that supports the seedling box 1 that accommodates the tailored seedling in parallel, the weight that the stand A that supports the seedling box 1 in parallel can not be handled alone. Therefore, on the loading platform t of the transport vehicle T, empty platforms A are mounted in parallel, and the seedling boxes 1 containing the tailored seedlings are inserted into the platforms A one by one in parallel. After the insertion and loading of the seedling box 1 to the gantry A is completed, the trolley A is transported to the field by driving the trolley T, and the gantry A mounted on the platform t of the trolley T in the field. Is left as it is, and the seedling boxes 1 are extracted one by one from the gantry A on the loading platform t and removed.

  Thus, the seedling carrying work performed using the platform A is performed by inserting the seedling box 1 into the platform A placed in parallel on the platform t of the transport vehicle T and loading the seedling box 1 to the periphery of the platform t. It is easy work for the platform A located in the section, but when inserting the seedling box 1 into the platform A located in the back of the loading platform t, it is impossible for the worker to get on the loading platform t or There is a problem that becomes a troublesome work because it will force a difficult attitude.

  Moreover, when the collection place of the seedling box 1 to be loaded is on one side of the loading platform t of the transport vehicle T, the loading platform A positioned on the periphery of the loading platform t with respect to the loading platform A positioned on the other side of the loading platform t. Even so, there is a problem that workability is poor because the nursery box 1 must be carried there. This problem also occurs when the seedling box 1 is removed.

  The problem to be solved in the present invention is to support a seedling box containing tailored seedlings in an upright posture by supporting one end of the box, and use a gantry that is supported in parallel by a large number of them. An object of the present invention is to facilitate loading and unloading of a nursery box on a platform on a loading platform of a transport vehicle when transporting to a field by a transport vehicle.

In the present invention, as means for solving the above-described problems,
The platform in which the nursery boxes containing the tailored seedlings are mounted in parallel in a posture that stands diagonally with the front and rear ends facing down is abbreviated to the front and rear length dimensions or left and right width dimensions of the carrier platform. The left and right side frames of the corresponding length and the support frame of the nursery box that is assembled in parallel between the side frames are assembled in a ladder shape, and a rail along the longitudinal direction is installed on the lower surface side of the assembled frame and, separately, to form a width of the base substantially corresponds to the load platform floor area of the truck, capable to mounted down taken up in the bed of the upper surface of the truck, the upper surface side of the base is a position corresponding to the rail to So設the lower surface side of each frame in a state where the rests by parallel said frame, and Katachi設trajectories fitted thereto, the fitting of the rail of the the said track frame, the Kassel said frame mounting by parallel array type on the upper surface side of the base, drawer own to the bed of the truck It is intended to raise the container for seedling transportation, characterized by being configured to containers for seedlings carried by the base block and the gantry allowed mounted on.
At the same time, the track provided on the base in the container for transporting seedlings described above is formed into a horizontal channel shape by forming a metal plate, assembled to the upper surface side of the horizontal frame of the base, and provided on the base A rail is formed in a lateral channel shape with the opening opening facing the opening opening of the channel-shaped track of the base by forming a metal plate, and is provided on the lower end side of the side frame of the frame. Means for fitting the rails in a state of biting each other, and slidably supporting the rails with respect to the track; and
In the container for transporting seedlings described above, the rail provided on the gantry is provided with a race ring on the front end side, and the track provided on the base is forward at a distance of about one quarter of the total length of the track from the rear end. Means for providing a stopper for stopping the movement of the gantry in the pulling-out direction after colliding with the raceway provided on the gantry at the part approaching
At the rear end of the base, adjacent to the two bases in each group when the bases that can be mounted in parallel on the upper surface of the base are divided into groups of two adjacent to each other on the left and right In the normal state, at the position corresponding to the rear surface of the unit, the drawer is prevented from being pulled out of the two frames, and the rotation is switched to a state in which one frame is prevented from being pulled out and the other frame is allowed to be pulled out. Means equipped with means, and
At the rear end side of the base, the locking piece is opposed to the regulating member provided on the base by pulling out the base at the part corresponding to each of the bases that can be mounted in parallel on the upper surface side of the base A check device that operates to move to the position to be moved is provided, and these check devices are linked so that they operate in synchronism by the operation of pulling out one base, and when one base is pulled out, the other platform is pulled out. It proposes a means to make it impossible.

  The container for transporting seedlings according to the present invention has a seedling box containing tailored seedlings mounted on a gantry in parallel, and when the gantry is placed on a carrier platform and transported to a field, the seedlings are grown on the gantry. For the work of suspending the box, pull the cradle mounted on the platform of the transport vehicle to the side of the cradle, and insert the seedling boxes one by one into the cradle, and slide the cradle sequentially to the back of the platform. Also, when removing the seedling box, by pulling out the seedling box from the front end side in the pull-out direction of the stand and pulling out the stand sequentially, or with the stand pulled out, The nursery box loaded in the back of the loading platform can be easily removed.

  According to the present invention, as claimed in claim 2, the fitting of the track provided on the base and the rail or guide wheel provided on the base is controlled so as to restrict the vertical movement, thereby pulling out the base. However, when the seedling box is taken down sequentially, the frame is pulled out longer, and the weight of the part pulled out of the frame becomes larger than the weight of the part remaining on the base, so that the terminal side in the drawing direction of the frame floats up, This prevents the rails or guide wheels of the gantry from coming off the base track.

  In addition, as described in claim 3, when a stopper is provided to stop the drawer of the gantry at a position slightly before the end of the drawer operation, the cradle is pulled out to a position where the gantry is pulled out. Since the nursery box is inserted into and loaded from the gantry and the nursery box is inserted and supported by the gantry, the operator located next to the gantry is easily operated.

  Further, as described in claim 4, when the base is provided with a restricting bracket for restricting the drawer of the gantry, the drawer of the gantry is limited to a desired gantry and an unintended gantry is placed on the gantry of the transport vehicle. This prevents the inconvenience that a large number of pedestals are pulled out at a time and the entire balance including the base is lost and falls from the loading platform.

  In addition, as described in claim 5, when it is made impossible to pull out another frame when one frame is pulled out, the above-mentioned whole generated by the operator pulling out a plurality of loading platforms To prevent the balance from being lost.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  3 to 5 show a first embodiment of a container for transporting seedlings in which the present invention is carried out. FIG. 3 is a side view of the entire container, FIG. 4 is a front view, and FIG. 5 is an exploded perspective view. FIG. In these figures, T is a transport vehicle, t is a loading platform of the transport vehicle T, A is a platform on which a large number of seedling boxes 1 are supported in parallel, and B is a base on which the platform A is mounted in a slidable manner. .

  W is a container for transporting seedlings in which a base B is mounted on a loading platform t, and a plurality of bases A arranged in parallel are slidably mounted on the upper surface side of the base B. Show the whole. In this example, the transport vehicle T is a truck, the loading platform t is the loading platform of the truck, and the left and right tilt plates and the rear tilt plates are omitted.

  As shown in FIGS. 6 to 8, the gantry A has left and right side frames 2 and 2 formed in a plate shape by a metal plate, and a support rod 3 for the seedling box 1 that is bridged in parallel between them. And a handle 20 for pulling out is provided on the rear end side.

  The left and right side frames 2 and 2 are formed so that the front and rear lengths correspond approximately to the front and rear lengths of the loading platform t of the transport vehicle T, and the distance between the left and right sides is the width of the nursery box 1. It is set so as to correspond to the dimensions, and one end side in the front-rear direction of the seedling box 1 can be inserted into this interval.

  On the opposite inner edge side of the left and right side frames 2 and 2, an edge frame-shaped bottom plate 21 that abuts and supports the left and right ends of the edge of the seedling box 1 inserted as shown by a chain line in FIG. Are formed.

  The support rod 3 holds the seedling box 1 in which the tailored seedling is housed in an oblique posture as shown in FIG. 9, and holds the seedling seedling inserted obliquely. A long support rod 3a provided so as to span between the left and right side frames 2 and 2 so as to support the bottom plate side of the box 1, and left and right so as to abut on the upper surface side of the seedling box 1 inserted in an oblique posture. It consists of the short support rod 3b which protrudes short from the inner wall surface of the side frame 2 * 2. The pair of long and short support rods 3a and 3b are arranged at intervals corresponding to the height dimension from the bottom surface of the seedling box 1 to the tip of the seedling housed in the seedling box 1 with the left and right side frames 2 and 3b. 2 in parallel with each other in the longitudinal direction.

  When a is mounted on the upper surface of the base B placed on the loading platform t of the transport vehicle T, a is fitted to a track b provided on the upper surface side of the base B, A rail provided on the lower surface side of the gantry A so that the gantry A is slidably mounted on the base B. In this example, the rail a is formed into a lateral channel shape by bending a metal plate, and the open portion of the channel faces both left and right outer sides of the gantry A to be assembled, as shown in FIG. The outer peripheral wall of the channel is installed on the lower end side of the side frames 2 and 2 so as to protrude in a shelf shape inside the left and right side frames 2 and 2.

  As shown in FIG. 8, the rail a is integrally connected to the side frames 2 and 2 by being continuously formed on the plate material such as an iron plate constituting the left and right side frames 2 and 2 described above. The side frames 2 and 2 are reinforced, and the bottom plate 21 of the mount A that supports the lower end of the nursery box 1 into which the upper surface of the lateral channel-shaped rail a is inserted is configured.

  Then, on this rail a, when the platform A is slidably assembled to the base B and mounted on the platform t of the transport vehicle T, the track ring c is pivoted on the front end portion on the front side of the platform t. Be supported.

  The base B is provided with a track b on which the base A is slid on the upper surface side so that the base A can be pulled out with respect to the base t of the transport vehicle T, and is mounted on the base t of the transport vehicle T. As shown in FIG. 5, the frame is placed on the upper surface of the horizontal frame 60 and a plurality of horizontal frames 60 extending in the horizontal direction parallel to the front-rear direction of the loading platform t of the transport vehicle T. The plurality of vertical frames 61 arranged in parallel in the left-right direction are formed into a flat frame shape having a size corresponding to the size of the loading platform t of the transport vehicle T.

  In this example, the track b provided on the upper surface side of the base B so as to slidably support the base A is formed by processing the above-described vertical frame 61 into a channel shape of a metal material such as an iron plate, When the channel material is placed in a horizontal posture in which the opening of the channel is directed to the side, the above-mentioned mounts A are mounted side by side on the upper surface of the horizontal frame 60, and the above-described mounts A are provided on the above-described mounts A. As shown in FIG. 10, a horizontal bottom surface on the lower end side of the lateral channel is brought into contact with a portion occupying a position corresponding to the rail a and is fixed by welding or bolt fastening. . The track b is pivotally supported on the rear end side thereof by a guide wheel 62 that supports and guides the rail a of the gantry A.

  The track b made of the channel material is assembled in such a manner that the open port of the channel is opposed to the open port of each channel-shaped rail a provided in the gantry A when fixedly mounted on the horizontal frame 60 described above. .

  And the vertical frame 61 which comprises this track | orbit b is in the vertical frame 61 located in the middle of the left and right except the vertical frame 61 located in the right and left sides of the base B, as shown in FIG. In addition, the tracks b made of adjacent channel members abut on each other back to back and are combined in a double manner.

  The insertion fit of the rail a provided on the gantry A to the track b provided on the base B is based on the state where the base B is mounted on the carrier t of the transport vehicle T, and the front end side of the base B Then, the rear end side of the rail a provided on the gantry A is fitted into the front end portion of the track b provided on the base B, and the gantry A is slid backward in this state.

  After fitting the rail a of the base A to the track b of the base B, the base A that is slidably supported with respect to the base B is prevented from slipping out of the base B past the base B. Therefore, in the middle of the trajectory b of the base B, a trajectory that is pivotally supported on the front end side of the rail a of the gantry A is located at a position that is approximately one-fourth of the longitudinal length from the rear end of the base B. A stopper S is provided that prevents further sliding of the gantry A by colliding with the wheel c.

  The base B and the base A are placed on the carrier t of the transport vehicle T in a state in which the rail a provided on the base A is slidably fitted to the track b provided on the base B. At this time, the base B is mounted such that the front end side thereof is directed to the front of the loading platform t, and the mounting platform A slidably mounted thereon is pulled out rearward from the rear edge of the loading platform t.

  d is a fixing means for fixing and holding the base B on the carrier t when the base B for slidably supporting the carrier A is placed on the carrier t of the transport vehicle T. In this example, A support column e is provided at the front end of the base B, and a loop f through which the rope is passed is provided above the support column e, and the rope passed through the loop f is fastened to a hook provided on the vehicle body of the transport vehicle T. However, it may be performed as appropriate, for example, by providing the base B with a mounting bracket such as a screw jack that is fixed to the vehicle body of the transport vehicle T and fixing it.

  Y sets one of the parallel platforms A from the carrier t in the state where the base B, which is slidably supported by the platforms A arranged in parallel on the carrier t of the transport vehicle T, is set. When the frame A is pulled out, another platform A different from the platform A intended to be pulled out protrudes from the loading platform t, and a plurality of platforms A are pulled out at a time. In order to prevent the gantry A from falling on the loading platform t together with the gantry B, a check means provided on the gantry B so that the drawer of the gantry A is restricted to only the intended gantry A is shown. .

  In this example, as shown in FIGS. 11 to 13, the restraining means Y is a rear end portion of the base B placed on the loading platform t, and the base A that is arranged in parallel on the base B. A support shaft 71 in the front-rear direction penetrating the horizontal frame 60 at the rear end of the base B in the front-rear direction by operating the handle 70 at a part corresponding to the rear surface of the adjacent part of the two adjacent bases A A rotating member 72 that rotates left and right at the center is provided, and a blocking member that faces the rear ends of the rails a and a of the two adjacent bases A and A on the upper portion of the rotating member 72. 73 is provided so as to rise up, and when the shape of the blocking member 73 is tilted to the left or right by the rotation of the rotating body 72 with the support shaft 71 as the center, The state where the rear end of the rail a of the gantry A is closed and the rear end of the rail a of the other gantry A is removed from the rear. Previously formed on. Further, in the normal state in which the handle 70 is not touched, the rotating member 72 is held at a position where the blocking member 73 closes the rear ends of the rear ends of the rails aa of the adjacent gantry AA. In this way, it is configured by being urged by a flexible spring material 75.

  And this check means Y is respectively installed in the rear position of the adjacent part of the base A and the base A in each group when the bases A arranged in parallel are divided into groups of two adjacent stations. Set up. As a result, the handle 70 is grasped and the rotating body 72 is rotated to the left as shown in FIG. 13, and the dam member 73 is removed laterally from the rear end of the rail a of the right base A, When the upper platform A is pulled out by grasping the handle 20, there is no inconvenience that the left platform A that is not intended to be pulled out is pulled out.

  FIGS. 14 to 22 show a state in which one base A is pulled out in a state where the bases B each slidably supported by the bases A arranged in parallel are set on the carrier t of the transport vehicle T. FIG. 5 shows another example of the restraining means installed on the base B so as to restrict the other base from being pulled out.

  In this example, when one of the parallel mounting bases A is pulled out, even if the operator tries to pull out the other mounting bases A together, a plurality of mounting bases A are pulled out at a time so that they cannot be pulled out. It is a restraining means that is trying to prevent the situation from becoming a state.

  More specifically, each base A mounted in parallel on the base B has a lower end side of a locking pin 80 fixed to the rear end of each rail a and a rear end of the base B. When the base A is fixed in the pushed-in state on the base B by being inserted into a hole formed in the leaf spring 81 provided on the lower surface side of the rear end portion of the track b, and the base A is pulled out The plate spring 81 is pushed downward to disengage the locking pin 80 so that the frame A can be pulled out, and the frame A can be pulled out only for the intended frame A. In this case, when the operator pulls out one gantry A, the checking means prevents the other gantry A from being pulled out.

  In this embodiment, the checking means for this purpose is that a support shaft 90 extending in the left-right direction is pivotally supported at the rear end portion of the base B serving as a drawer port of the gantry A, and the support shaft 90 is arranged in parallel. Actuating members 91 whose both front and rear end portions swing up and down around the support shaft 90 are arranged at portions adjacent to the rails a of the gantry A, respectively. The member 91 is provided with an operating piece 92 facing the lower side of the bottom surface of the rail a provided on the gantry A on the rear end side, and on the front end side, the operating piece 92 on the rear end side is the lower surface of the bottom wall of the rail a. A locking piece 94 is provided that rises to a position where it abuts against the regulating member 93 provided on the outer surface of the rail a of the gantry A by swinging and rotating of the operating member 91 by being pressed down while being in contact with deep.

  The operating member 91 has the bottom surface fixed to the support shaft 90 by welding, so that the operating piece 92 contacts the bottom surface of the rail a of the gantry A and the center of the support shaft 90 as shown in FIG. 18, the support shaft 90 rotates together with the torsion spring 95 wound around the support shaft 90, and the actuating member 91 is centered on the support shaft 90 counterclockwise in FIG. 18. By acting between the horizontal frame 60 of the base B and the operating member 91 so as to rotate, the operating member 91 is held in a state where the locking piece 94 provided on the front end side is lowered as shown in FIG. deep.

  In this state, the operating piece 92 occupying the raised position comes into contact with the lower surface of the bottom wall of the rail a provided on the gantry A, but the rail a provided on the gantry A is notched at the rear end portion of the bottom wall. By forming the portion 96 and inserting the operating piece 92 into the notch 96, there is no contact of the operating piece 92 with the lower surface of the bottom wall of the rail a, and as shown in FIG. I try to be in the state.

  The notch 96 is provided in a range from the rear end of the rail a to a position at a distance D, and the rail a moves backward by pulling the gantry A by this distance D, so that the rail a of the operating piece 92 is provided. Then, the contact with the lower surface of the bottom wall starts, and the actuating member 91 rotates clockwise around the support shaft 90, and as shown by the solid line in FIG. It will be in the state which occupies the position which hits 93.

  At this time, the regulating member 93 provided on the outer surface of the rail a of the gantry A has moved to the position indicated by the chain line by pulling the gantry A to the position indicated by the chain line in FIG. For this reason, the locking piece 94 that is turned upward by pulling out the gantry A comes to rise beyond the regulating member 93 that has moved.

  From this, the drawn base A is not subject to the restriction by the restriction member 93, and the track ring c mounted on the front end of the rail a of the base A is mounted on the stopper S provided on the track b of the base B as it is. It is pulled out to a position where it comes into contact and the drawing is restricted.

  However, the operation member 91 at the check position provided at the position adjacent to the rail a of the other gantry A in parallel is supported by the support shaft 90 that rotates together with the activating member 91 that rotates by pulling out the one gantry A described above. 18 is rotated in the same state as the actuating member 91 shown in FIG. 18, the other support A in parallel tries to pull it out, so that the regulating member 93 is a locking piece on the front end side of the actuating member 91. 94, the drawer is restricted.

  Therefore, when one gantry A is pulled out, the other gantry A in parallel cannot be pulled out by its pulling operation.

  21 to 23 show still another embodiment. In this example, on the upper surface side of the base B, the bases A for loading the seedling boxes 1 in parallel and in parallel are arranged in parallel, and each base A is mounted so that it can be pulled out freely. When a container for carrying seedlings is constructed by being mounted on t, the base B on which the base A is supported in parallel is placed so that the front-rear direction thereof is along the left-right direction of the base t of the transport vehicle T. In this example, the platform A mounted on the base B and drawn on the base B is pulled out on the side of the loading platform t of the transport vehicle T.

  The base B and the gantry A in this example are described above, except that their length in the front-rear direction corresponds to the length in the left-right width direction of the loading platform t of the transport vehicle T. The configuration is the same as that of the embodiment. For this reason, with respect to each component member, the same component member is denoted by the same reference numeral, and detailed description thereof is omitted.
