The rotating shaft 39b3 is rotated by the driving of the rotating shaft, and the second moving link member 39b integral with the rotating shaft 39b3 is rotated at the same time so that the first, second and third moving link members 39a, 39b, 39c) is switched to the stacked state and the developed state.

The operation control block diagram of the spare seedling loading stand 38a, 38b, 38c is shown in FIG.

Switching switch 73 (may be a button or a lever) as switching operation means for switching the preliminary seedling loading tables 38a, 38b, 38c by the switching drive device 70 in a deployed state and a stacked state (FIG. 1, FIG. 1). 2) is installed in the vicinity of the seat 31, and as shown in the simplified diagrams of Figs. 4 and 6, the preliminary seedling loading tables 38a and 38b are in a deployed state or stacked state by the operation of the switching switch 73. , The stop plates 73a1 and 73a2 for stopping these preliminary seedling stacks 38a, 38b, and 38c when rotating by 38c are replaced by the third preliminary seedling stack 38b and the second preliminary seedling stack 38c. Installed on each side. The stop plate 73a1 has a second moving link member 39b on the stop plate 73a1 when the preliminary seedling loading tables 38a, 38b, and 38c are stacked, thereby overloading the electric motor 71 and causing excessive voltage. Is a member which stops the operation by overheating or overheating, and the stop plate 73a2 has an electric motor (2) in the second moving link member 39b when the preliminary seedling loading tables 38a, 38b, 38c are in a deployed state. 71) Overloading to generate excessive voltage, or overheating to stop the operation.

In addition, when the stop plates 73a1 and 73a2 keep in contact with the second moving link member 39b, the load (the second moving link member 39b contacts the stop plate 73a1 or 73a2 and rotates more than that). Although it is impossible to do this, it is the load of the electric motor 71 which continues to drive, and the electric current path which uses the bimetal 85 is arrange | positioned inside the electric motor 71, when it heats by a load or an excessive voltage is applied, The bimetal 85 is bent (retracted), the energization is stopped, and the rotation of the electric motor 71 is stopped.In the case of the voltage type, the operation can be performed immediately after the stop. The electric motor 71 is stopped by the heat of 85) is reduced and does not operate until it returns to its original state, and since the operator does not have to stop the electric motor 71, it is possible to concentrate on other operations. Efficiency is improved over the prior art.

In addition, when the preliminary seedling loading table 38a, 38b, 38c is in the expanded state or the stacked state, the second moving link member 39b is configured to come into contact with the stop plate 73a1 or 73a2. This prevents the second moving link member 39b from moving and swinging the first, second, and third preliminary seedling loading tables 38a, 38b, and 38c back and forth, preventing the seedling from falling and making the first by shaking. In addition, wear of the second and third preliminary seedling loading tables 38a, 38b, 38c and other components for preliminary seedling loading is reduced.

In addition, when the 1st, 2nd, 3rd preliminary seedling loading table 38a, 38b, 38c is made into the expanded state or the stacked state, structural members and circuits, such as a switch for stopping the electric motor 71, can be omitted. This reduces the number of parts and greatly simplifies the construction.

In the case of using a conventional limit switch, since the switch requires a cable or a circuit to which the moving link members 39b and 39c send a stop signal at the same time as the contact, the number of parts is large and the structure is complicated. In addition, since the limit switch stopped in the deployed state and the limit switch stopped in the stacked state are required, the number of parts is further increased and the structure is complicated.

On the other hand, in the present invention, when the bimetal 85 in the electric motor 71 retracts (bents) by overvoltage or overheating, the electric motor 71 is automatically stopped, and thus a path for transmitting the stop signal is unnecessary. Since only a switch for operating the electric motor 71 in a deployed state and a stacked state is provided, the switch and the electric motor need only be connected by a cable, thereby reducing the number of parts and simplifying the structure.

In addition, as shown in FIG. 5, when the 1st, 2nd, 3rd preliminary seedling loading tables 38a, 38b, 38c are in an expanded state, the 1st, 2nd, 3rd moving link members 39a, 39b The stop plate 73a1 which stops the movement of 39c is arrange | positioned at the 2nd preliminary seedling loading stand 38b of the center end, and as shown in FIG. 3, a 1st, 2nd, 3rd preliminary seedling loading stand A stop plate 73a2 for stopping the first, second, and third movable link members 39a, 39b, 39c in the stacked state of (38a, 38b, 38c) is attached to the lower third preliminary seedling loading table 38c. By arrange | positioning, since it becomes the structure which the 1st, 2nd, 3rd moving link members 39a, 39b, 39c contact in the position which becomes the said expanded state or the stacked state, it can be made simple.

In addition, since the first, second, and third moving link members 39a, 39b, and 39c come into contact with the stop plates 73a1 and 73a2 and stop, the first, second, and third movements are caused by the vibration of the gas. The link members 39a, 39b, 39c are moved to prevent the first, second, and third preliminary seedling loading tables 38a, 38b, 38c from swinging back and forth, preventing the seedling from falling, and the first by shaking. The wear of the second and third preliminary seedling loading tables 38a, 38b, 38c and the members around them is reduced.

Moreover, since the contact of the 1st, 2nd, 3rd moving link members 39a, 39b, 39c, and the stop plates 73a1, 73a2 becomes easy to apply the load to the electric motor 71, Stops faster and consumes less power.

9 (a) and 9 (b) show simplified views of the loading state and the unfolding state of the first, second and third preliminary seedling loading tables 38a, 38b and 38c, which are other embodiments of the present invention, respectively. Indicates. The stop plates 73a1 and 73a2 in this case are provided in the front and back side of the 2nd preliminary seedling loading board 38b, respectively.

In this case, when the 1st, 2nd, 3rd preliminary seedling loading table 38a, 38b, 38c is made into the stacking state, the upper and lower ends of the 2nd moving link member 39b are attached to the stop plate 73a1, 73a2, respectively. Since the first, second and third moving link members 39a, 39b and 39c come into a stopped state in contact with each other, the first, second and third moving link members 39a, 39b and 39c are caused by the vibration of the gas. Movement of the first, second and third preliminary seedling loading tables 38a, 38b, 38c is prevented from shaking back and forth, and the fall of the seedlings is prevented, and the first, second and third preliminary seedling loading tables due to shaking are prevented. Wear of constituent members including 38a, 38b, 38c is reduced.

Moreover, when the 1st, 2nd, 3rd preliminary seedling loading table 38a, 38b, 38c switches from a loading state to a deployment state, it shows a partial enlarged view in the round frame A, B of FIG. 9 (b). As described above, since the second movable link member 39b and the first and third movable link members 39a and 39c are configured to sandwich the stop plates 73a1 and 73a2, respectively, the first, second and third movable link members 39a, 39b, and 39c are locked, and the first, second, and third moving link members 39a, 39b, and 39c are prevented from moving back and forth by the vibration of the gas to prevent the seedling from falling. In addition, wear of the constituent members of the spare seedling loading table due to shaking is reduced.

As shown in the plan view of the switching drive device 70 of FIG. 10 (a) and the internal structure diagram of the switching drive device 70 of FIG. 10 (b), in this embodiment, the cover plate constituting the switching drive device 70 is constituted. The driving gear of the electric motor 71 is shifted out of phase with the rotation shaft 81 of the switching gear 70a which moves the first, second and third moving link members 39a, 39b, 39c to the 78. The auxiliary plate 79 provided with the rotation shaft 71a1 of 71a is mounted. Then, the motor mounting plate (holding plate) 80 is mounted over the cover plate 78 and the auxiliary plate 79, and the electric motor 71 for rotating the rotating gear 70a on the holding plate 80 is mounted. We adopt structure to attach more.

In the switching drive device 70 which consists of the said structure, since the holding plate 80 is provided over the cover plate 78 and the auxiliary plate 79, and the electric motor 71 is attached to this holding plate 80, When the first, second, and third movable link members 39a, 39b, 39c contact the stop plates 73a1, 73a2 and are under load, the force released by the electric motor 71 is applied to the retaining plate 80. Since the cover plate 78 receives the force, the holding plate 80 becomes difficult to bend.

In addition, since the force is not applied to the electric motor 71 by the load, the separation of the electric motor 71 is prevented and the distance between the electric motor 71 and the switching gear 70a is prevented, so that the switching drive device ( The adjustment work of 70) is omitted, thereby reducing the effort of the operator.

As the top view of the switching drive apparatus of the 1st, 2nd, 3rd preliminary seedling loading stand 38a, 38b, 38c is shown in FIG. 11, a switching drive apparatus centering on the side part of the 2nd preliminary seedling loading stand 38b. A guide cover 88 covering 70 is provided, and the guide cover 88 covers the main cover 83 covering the drive gear 71a of the electric motor 71 and an auxiliary cover covering the electric motor 71 ( 82, the main cover 83 is connected to the cover plate 78, and the auxiliary cover 82 is connected to the main cover 83 and the cover plate 78.

With the configuration shown in FIG. 11, except for the auxiliary cover 82, the electric motor 71 and the retaining plate 80 are exposed, so that the entire guide cover 88 can be adjusted or cleaned without being removed for each maintenance. It is improved more than ever.

The electric motor 71 may be built with a bimetal 85 (shown only in FIG. 8) that deforms and stops the energized state when a load is applied to generate heat above a predetermined temperature. In this way, if the electric motor 71 is overloaded to generate an overvoltage or an overheat, and the predetermined temperature is higher than the predetermined temperature, the bimetal 85 is deformed to stop the electricity supply, and thus, the first, second and third preliminary seedling loading tables If the electric motor 71 is overheated when the 38a, 38b, 38c is in the deployed state or the stacked state, the motor is stopped because it overheats. Therefore, there is no need to perform the stop operation of the electric motor 71.

In addition, as shown to the side view of the preliminary seedling loading board of FIG. 12 (a), FIG. 12 (b), the top view of FIG. 12 (c), and the enlarged view of the front side protrusion of the preliminary seedling loading board of FIG. In the front end portions of the second and third preliminary seedling loading tables 38a, 38b, and 38c, the front protrusions 38b1 and 38c1 protruding toward the front are formed, respectively, but these front protrusions 38b1 and 38c1. The rear upward inclined surface is formed, and the conveyance auxiliary rollers 47b and 47c which disperse | distribute to each front side protrusion part 38b1 and 38c1 and assist a seedling conveyance are arrange | positioned, respectively. Moreover, the upper surface of the conveyance auxiliary rollers 47b and 47c has a structure which protrudes upwards rather than the upper part of the rear upward inclination surface of the said front side protrusion parts 38b1 and 38c1.

In addition, the seedling box mounting member 101 shown to FIG. 13 and FIG. 14 is demonstrated.

The seedling box mounting member 101 which mounts the seedling box 68 is provided in the outer side of the base of the 1st, 2nd, 3rd preliminary seedling loading boards 38a, 38b, 38c, respectively. Since the seedling box loading member 101 is fixed to the preliminary seedling loading stand, it is set as the structure which moves with a preliminary seedling loading stand.

Moreover, it is comprised from the wire rod, and the body front-back direction and upper direction are open, and the inclination is formed in the front-back edge part of the seedling box loading member 101. As shown in FIG. For this reason, the seedling box 68 can be made to go in and out from the front-back direction and upper direction of a base, and when a seedling box 68 is mounted to the seedling box loading member 101 by inclination, it is prevented from falling by the vibration of a gas. have.

In addition, when the 1st, 2nd, 3rd preliminary seedling loading boards 38a, 38b, 38c are switched from a loading state to a deployment state, the seedling box loading member 101 is also similar to the seedling box loading member 101 as the upper and lower sides of a base body. It is switched from the individual moving state 101b arranged in the direction to the total moving state 101a arranged in the gas front-back direction.

As for the whole moving state 101a, since the seedling box loading member 101 arranges in the front-back direction of a base | substrate, the seedling box loading member 101 becomes an adjacent rail shape, and it is easy to pile up the seedling box 68 by packing from a base body. .

In addition, since the seedling box 68 loaded on the seedling box stacking member 101 can be easily taken out from the packaging side, workability is improved.

In addition, the seedling box stacking member 101 located at the rear of the body at the entire moving state 101a is positioned above the seedling box stacking member 101 located at the front of the body, thereby smoothing the seedling box 68. Can be sent in front of the aircraft.

In addition, the seedling box mounting member 101 is comprised so that the seedling box 68 may be loaded in an oblique attitude toward the outside of the body. By doing so, when the 1st, 2nd, 3rd preliminary seedling loading table 38a, 38b, 38c is a loading state (individual movement state 101b), the seedling box 68 is inclined in a gas inside and a preliminary seedling loading stand Contact with 38 can be prevented.

In addition, it is switchable to the whole moving state 101a and the individual moving state 101b in the state which mounted the seedling box 68 to the seedling box mounting member 101. As shown in FIG. In the individual movement state 101b, the seedling box stacking member 101 is spaced apart from each other and arranged in the up-down direction of the body, whereby the seedling box stacking member 101 located above fixes the seedling box 68 located below. Playing a role. In addition, the seedling box 68 mounted on the top can prevent the fall from the base by another fixing member (not shown).

Moreover, the shape in which the front end part and the rear end part of the seedling box mounting member 101 were bent toward gas upper direction is formed. As a result, the seedling box 68 does not slip off during vibration of the body or the slope.
