[Prior art]

 Recently, as a seedling raising container used for cultivating vegetables such as agricultural crops, a paper-made tube-shaped seedling raising container for transplantation (hereinafter referred to as a seedling raising container) is generally used. This seedling raising container is a group of paper-made cylinders made by adhering a number of bottomless paper cylinders with a water-soluble glue and forming a hexagonal columnar shape when viewed from an independent plane. After seeding, seeding, and raising seedlings, they are each divided into individual paper cylinders, which are then transplanted to the field using a dedicated transplanter.

Conventionally, as a device for performing seeding work from soil filling using this seedling raising container, a soil filling device integrated with a reversing device as shown in FIG. 6 is known. The outline of the work process of the soil filling device 1 is as follows. The seedling raising container 3 is spread on the protrusion plate 2 and placed on the base plate 4 of the soil filling device 1. The seedling raising container 5 is put on the seedling raising container 3 and a predetermined amount of bed soil is put therein. Even the floor soil with a soil leveler. The handle 5 is moved to the left and right, shock vibration is applied to the base plate 4 several times, and the paper cylinders 7, 7, ... Of the seedling raising container 3 are filled with soil. Remove the soil-filling frame 5, scrape off the remaining floor soil, and cover the nursery container 3 with a flat reversal plate (not shown). A band (not shown) is hung on the reversing plate, and the handle 8 is manually operated to invert the seedling raising container 3 to the front side of the reversing table (not shown), and the projecting plate 2 is removed. The seeds are sown in the recesses formed in each paper cylinder of the seedling raising container 3 and covered with soil. While supporting the seedling-growing container 3 with the reversal plate, the seedling-growing container 3 is moved to the house and transferred to the nursery.

On the other hand, the outline of the working process of the soil filling device 10 different from the soil filling device 1 is as shown in FIG. The seedling raising container 3 is spread on the projecting plate 11 and placed on the base plate 12 (conveyor) of the soil filling device 10. A predetermined amount of bed soil is placed in the seedling raising container 3. Impact is applied to the base plate 12 (conveyor) to fill the paper cylinders 7, 7 ,. The soil left on the surface of the seedling raising container 3 is scraped off and covered with a flat inverted plate 13. The reversing plate 13 is transferred to the reversing device 14. The seedling raising container 3 is manually turned out 180 ° by the reversing device 14 and transferred to the next conveyor 15. The protrusion plate 11 is removed, seeded, and covered with soil. The nursery container 3 is transferred to the nursery of the house.

Work to remove 2, 11 is an essential step. In any of the above cases, this reversing work is performed manually, so that the seedling raising container 3 is stagnated at the stage of the reversing process, which hinders efficient seeding work. In addition, since the seedling raising container filled with soil is heavy, this reversal work is a heavy labor, and improvement is required. The present invention is intended to solve such a problem, and its purpose is to automate a reversing device in a soil filling machine that uses a seedling raising container, to make continuous sowing work and reduce labor, and to perform sowing work. An object of the present invention is to provide an automatic reversing device for raising seedlings, which can improve the efficiency of

The drive shaft 51 is provided with sprockets 55, 55, respectively, and a roller chain 57 is hung between the drive shaft 51 and the transport motor 56 to drive the transport conveyors 47, 48 in the right direction of the arrow to transport the seedling raising container 3. Has been done. Reference numeral 58 is a pair of guides, and the distance between the guides 58, 58 can be arbitrarily adjusted according to the lateral width of the seedling raising container 3 via a screw portion on the support rods 45, 45.

On the other hand, a roller chain 61 is wound around the outer peripheral surfaces of the rotary frames 44 a and 44 b via a support tool 60, and one tension sprocket 63 and a counter shaft 64 provided on the horizontal rod 41 of the mounting table 40. The sprocket 65 and the other tension sprocket 66 are returned to the support 60. The counter shaft 64 is connected to the sprocket 68 of the reversing motor 67 and the sprocket 69 of the counter shaft 64 via a roller chain 70 that is suspended.

Further, stopper supports 71 such as square pipes are provided upright at the ends of the connecting bodies 46, 46 of the rotary frame 44, and stoppers 72 made of an elastic body such as hard rubber are attached to both ends thereof.

Is installed. When the light beam is output from the light projecting unit of the light projecting / receiving unit F1, the light beam is reflected by the facing reflector 80 and enters the light receiving unit of the light projecting / receiving unit F1. Therefore, when the seedling raising container 3 passes, the light beam is blocked and the relay connected to the emitter / receiver F1 is activated.

The automatic reversing device 22 having the above-described structure is shown in FIG. 5 as an example of the control device 23 for the conveying motor 56 and the reversing motor 67 for automatically reversing the seedling raising container 3. Using a circuit. In the initial state, when the contact of the limit switch LS1 is closed, the relay C2 works. When the start switch PBS1 is pressed, the relay C1 is activated, and the relay C1 is closed at three points, self-holding, the contactor M1 for the carry motor is closed, and the carry motor 56 is activated.

The transfer motor 56 starts operating, the transfer conveyors 47 and 48 start moving, and the seedling-growing container 3 sandwiched between the projecting plate 25 and the reversing plate 37 is transferred from the soil filling device 21 to the transfer conveyor 27. While being conveyed, the conveyors 47 and 48 of the automatic reversing device 22 are entered, the light emitting / receiving device F1 operates, and the contact a of F1 is closed.

On the other hand, when the seedling raising container 3 is conveyed to the conveying device 23 and is separated from the sight of the light emitting / receiving device F1, the light emitting / receiving device F1 returns to a state of waiting for the next seedling raising container 3. When the next seedling raising container 3 is transferred to the transfer conveyors 47 and 48, the emitter / receiver F1 is activated, the contact a of F1 is closed, and the contact of the relay C5 is closed. Therefore, the reversing contactor M2A for the reversing motor operates, the reversing voltage is applied to the reversing motor 67, the reversing motor 67 rotates in the opposite direction to the above, and the rotary frame 44 rotates in the 180 ° reverse direction. .

When the rotary frame body 44 is rotated in the opposite direction by 180 ° in this way, one operating body 74 located above is lowered and abutted against the limit switch LS1, and is connected to the limit switch LS1. The relay C2 is actuated, the transport motor contactor M1 operates, the transport motor 56 drives the transport conveyors 47 and 48, and the seedling raising container 3 is transported to the transport device 23. By this transportation, when the seedling raising container 3 moves away from the field of view of the light emitting / receiving device F1, the light emitting / receiving device F1 returns to a state of waiting for the next seedling raising container 3.

The automatic seedling raising container reversing device according to the present invention is configured as described above, and is capable of automatically and continuously reversing the seedling raising container sandwiched between the projecting plate and the reversing plate. The seeding work can be lined up. In addition, the seeding work can be streamlined by reducing the heavy labor associated with the conventional manual reversal work of the worker.
