First, the configurations of the tray T and the seedling raising pot P will be described with reference to FIGS. The tray T is made of synthetic resin or the like, is lightweight and durable, and is suitable for loading and carrying. The tray bottom has a large number of draining holes. The seedling-growing pot P is made of a soft material, and is composed of a large number of cell parts Pa each having seeds planted one by one, and having concave portions formed like rice grains for raising seedlings and having draining holes at the bottom. There is. At the time of transportation in the seeding plant described later, the seedling-growing pot P is placed inside the tray T to have a shape as shown in FIG.

Next, an overall configuration of a sowing plant, which is an example of a soil filling device, will be described with reference to FIG. The seeding plant shown in the figure has a soil filling device A, an irrigation device B, a pressure suppression device C, a seeding device D, a soil covering device E, and an irrigation device F provided on an automatic transfer device R. When the tray T containing the above is supplied from the X side onto the automatic transfer device R, in the process of being automatically transferred, soil filling, sowing, etc. are performed, and the seeded pot T in the nursery pot is carried out from the Y side. To do.

The seedling raising pot P in the conveyed tray T is filled with soil by the soil filling device A, leveled, and watered by the irrigation device B. A soil collecting device A'is installed at the rear of the soil filling device A to collect the excess soil that is supplied from the soil filling device A and drops below the automatic transport device R. After passing through the irrigation device B, the pressure suppression device C rotates a roller that radially projects a large number of protrusions to form seeding holes in the soil in each cell portion Pa of the seedling-growing pot P, and then the seeding device. Seeding is performed in the holes at D. The seeded nursery pot P is covered with soil by the soil cover device E and irrigated by the irrigation device F, so that the seeding is completed.

The configuration of the automatic transfer device R in the tray supply side and the soil filling device A will be described with reference to FIGS. 3 to 6. The automatic transfer device R has transfer rollers 3 and 3 fixedly mounted on the transfer rotation shafts 2 and 2, which are pivotally supported between the left and right transfer racks 1 and 1, respectively. The sprocket 4 is fixed at one end, and the chain 5 is wound around the adjacent sprockets 4. Then, a sprocket 6 is fixedly mounted on any one of the transport rotary shafts 2, and this is driven by a transport motor M1 provided in the soil filling device A via a chain 5a to rotate the entire transport shaft. The drive shaft 2 is driven to carry the tray T placed on the carrying roller 3.

The soil filling device A comprises a filling portion A1 and a leveling portion A2. The filling portion A1 feeds the soil from the upper hopper 7, and drives it by a feeding port 7a at the bottom of the hopper 7. It is dropped onto the belt 8 and the soil is dropped into the seedling-growing pot P in the tray T 1 conveyed below the belt 8 to fill the cell portion Pa. The belt 8 is driven by a belt driving motor M2 via a chain 5b. The belt driving motor M2 is started when the leading end of the conveyed tray T is pressed against the tray detection switch S1. However, the drive is stopped when the terminal end of the tray T leaves the tray detection switch S2, and is driven when either one of the tray detection switches S1 and S2 is ON.

The belt 8, the belt driving motor M2, and the conveying motor M1 are covered with a filling portion cover 9. Reference numeral 10 is a shutter for adjusting the amount of soil supply at the supply port 7a, which can be rotated by a lever 10a. The lower end of the shutter 10 is positioned at the end of the horizontal portion of the belt 8 and the belt 8 is rotated. After stopping the shutter and closing the shutter 10, the soil is prevented from falling from the curved portion at the end of the belt 8. Further, a stirring rod 11 is arranged in the hopper 7, and a chain 5c is wound around a drive shaft 8a of the belt 8 around a sprocket 11a attached to the rotation shaft of the stirring rod 11.

The leveling section A2 roughly removes excess soil accumulated on the seedling-growing pot P filled with soil in the filling section A1 with a rotating brush 12 and leveles the topsoil with a leveling roller 13. Then, the soil which is deflected by leveling and accumulated is removed by the rotating brush 14, and the soil in each cell portion Pa of the seedling-growing pot P is prepared so that it can be sown. The shape of the rotating brushes 12 and 14 is such that brushes are planted around the rotating rollers, and both rotating brushes 12 and 14 and the leveling roller 13 are driven by the rotation of the transport rotating shaft 2. Then, the leveling drive shaft 15 is laterally provided between the transport bases 1 and 1, and one of the transport rotary shafts 2 is meshed with the gears 16 and 16. Further, the chains 5d and 5e are wound around the leveling drive shaft 15 around the rotary brush 12 and the leveling roller 13, respectively, and the chain 5f is wound around the rotary brush 14 from one of the transport rotary shafts 2. Turn and drive.

Since the leveling drive shaft 15 is driven via the gears 16 and 16, the leveling drive shaft 15 rotates in the direction opposite to the direction of the transport drive shaft 2, so that the rotating brush 12 and the leveling roller 13 are While contacting the seedling raising pot P on the conveyed tray T while rotating in the traveling direction, the rotary brush 14 rotates in the same direction as the transporting rotation shaft 2, so that the seedling raising pot has a moving direction. Abut in opposite directions. This is to ensure the removal of excess soil on the pot, but with the rotation of the rotating brush 14 that rotates in the opposite direction to the transport direction, the seedling pot P made of a soft material is slightly raised from the tray T. Then, as shown in FIG. 14, it is wound up by the rotating brush 14. There, the pot restraining tools 21, 21 formed into a boat shape by wires or the like are arranged parallel to the traveling direction to fix the front end, and the pot end is gradually pushed down as the tray is transported. Further, a leveling hanging rubber 17 is provided next to the rotary brush 14 so as to finish the leveling of the soil in the seedling raising pot P on the tray to be conveyed.

The rotating brushes 12 and 14 and the leveling roller 13 described above are arranged inside the leveling section cover 22, and the leveling roller 13 and the rotating brush 14 are further supported by the side plate 23 inside the leveling section. The rotary shafts are rotatably fitted in the leveling part inside plate 23. Further, the rotating shafts 13a and 14a of the leveling roller 13 and the rotating brush 14 are fitted into the long holes 22a and 22b formed in the leveling portion cover 22, and the roller links 18 and 18 are attached from both ends of the rotating shaft 13a. Brush links 19, 19 are connected to the leveling drive shaft 15 from both ends of the rotary shaft 14a, and to the transport rotary shaft 2 that is the drive shaft of the rotary brush 14. Further, the ends of the leveling height adjusting handle 20 are attached to both ends of the rotary shaft 14a, and the leveling height adjusting handle 20 is pivotally supported on the leveling part cover 22 at the rotation fulcrums 20a and 20a. To be rotatable. Further, pressing portions 20b and 20b are provided on both sides of the leveling height adjusting handle 20 so that the handle fixing screws 24 attached to both sides of the leveling portion cover 22 are pressed.

With the above configuration, the rotation shaft 14a of the rotating brush 14 is moved within the range of fitting into the slot 22b by operating the leveling height adjusting handle 20, and the leveling roller is Since the rotary shaft 13a of 13 is fitted in the long hole 22a, the rotary shaft 13a also moves integrally with the movement of the rotary shaft 14a via the leveling part inner side plate 23. In this way, the flat height is adjusted by operating the flat height adjusting handle 20, and when the flat height is adjusted to an appropriate height, the flat screw adjusting screw 24 is used to adjust the flat height. When the handle 20 is fixed, the leveling roller 13, the rotating brush 14, and the leveling part inner side plate 23 are fixed at the position.

It should be noted that the fitting insertion hole 24a in the flattening part inner side plate 24 into which the rotary shaft 13a of the leveling roller 13 is fitted is also made into a long hole, and the tip end of the roller link 18 is provided with a long hole. The roller height adjusting hole 18a is provided, and the roller height adjusting screw 25 is engaged with the leveling portion cover 22, so that the engaging point is within the range of the roller height adjusting hole 18a. Since the rotary shaft 13a can also be moved within the range of the fitting hole 24a by adjusting the position of the roller link 18, the link angle of the roller link 18 with respect to the horizontal direction can be adjusted independently of the brush link 19. is there.

At the lower part of the transportation platform 1, there is provided a recovery casing 26 for receiving the extra soil falling downward at the roller 8 and the leveling portion A2. The extra soil accumulated in the recovery casing 26 is It is recovered by the soil recovery device A ′ and is again supplied into the upper hopper 7.

The tray T and the seedling raising pot P, which have been filled and leveled with the soil by the soil filling device A configured as described above, receive irrigation by the irrigation device B in the next step, and are compressed. At the position C, a seeding hole is provided on the topsoil for each cell portion Pa of the seedling raising pot P, and the seeding device D is used to sow the holes. As shown in FIG. 9, the crusher C supports a crusher roller 27 and rotates as the seedling pot P of the tray T being conveyed advances, and the crusher 26a is inserted into the top soil in each cell portion Pa. The seeding holes are then constructed.

As shown in FIG. 11, the seeding device D has a shape as shown in FIG. 10, which is configured by a seed plate 28 which slides seeds from a seed hopper 27 arranged at the upper part by a driving force of a motor M3. Of the seedling raising pot P, and dropped into the holes 28a corresponding to the number of cell portions Pa in the right and left rows of the seedling raising pot P, and further dropped into the sowing hose 29 corresponding to the number of cell portions Pa in the horizontal row of the seedling raising pot P. The seeds are sown in the seeding holes of the top soil in the cell portion Pa. Therefore, in the seeding device D, since the motor has to be started in accordance with the timing of seeding and the tray transfer, immediately before the seeding device D, the side end of the tray T to be transferred is pushed. A sowing tray detection sensor S3 for inputting is provided.

Conventionally, the tray position sensor S3 has a shape as shown in FIG. 12, and the pusher 30 is rotated by pushing the tray T, and the contact 31a of the switch 31 is pushed in to turn on the switch. However, when the tray T is pulled in the direction opposite to the advancing direction, the contact 31a is destroyed when the tray T is returned beyond the contact 31a. Therefore, in order to protect the switch 31, the pusher 30 is restored to the home position. The return spring 32 was attached to the contact 31a to make it weaker than the spring force of the contact 31a so that the contact 31a was not pressed. Therefore, since the return spring 32 cannot be strengthened, fatigue is quick, and when the fatigue occurs, the restoring of the pusher 30 becomes unstable and the detection of the tray position becomes unstable.

Therefore, in the present embodiment, as shown in FIG. 13, the central portion of the pusher 33 is rotatably supported, and the torsion spring 33a is attached so that the tray side of the pusher 33 contacts the stopper 34. The pusher 33 is urged as much as possible, and an elastic body 33b such as a spring is attached to the tip of the pusher 33 on the tray side so that it can be avoided when an overload is applied, and the other end is in contact with the contact 31a. . Therefore, when the tray T is pushed, the pusher 33 is rotated to push in the contact 31a of the switch 31 to turn it ON. At this time, the pushing portion to the tray is such that the elastic body 33b moves in the tray advancing direction. When the tray T bends and the tray T passes, the spring pusher 33 returns and pushes against the stopper 34 at a fixed position to stop, and the spring portion at the tip also restores. As described above, since the pusher is stopped in place by the stopper 34 instead of the return spring 33, the restoration of the pusher is stable, and the pusher is not pushed onto the tray. Since this part is a spring, the tray and the presser are prevented from being damaged, and the presser can withstand long-term use, so that the tray detection in the seeding device can be performed normally for a long time. is there.
