Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a suppression device for a seeding device for pot sheets.

(Prior Art) Japanese Patent Application Laid-Open No. 63-209504 discloses that on a horizontal transfer table for transferring a storage box in which a rectangular pot sheet is fitted, a surface is placed on the floor in each pot of the pot sheet. A bed soil supply device is provided, and in front of the bed soil supply device, a first pressure roll and a second pressure roll are provided for compacting the floor in two stages, and directly below the first pressure roll and the second pressure roll. The position describes a seeding device equipped with a support roll that supports the entire width of the lower surface of the storage box.

(Problems to be Solved by the Invention) The known suppression device has a leading pot sheet and a trailing pot seat.
) The sheets are being transported continuously without any gaps, but when the leading edge of the trailing pot sheet reaches below the pressure roll, the transport speed slows down due to the resistance when it is sandwiched between the pressure roll and the support roll. A gap is created between the leading pot sheet and the trailing pot sheet on the front side of the pressing roll, and soil falls from the gap and adheres to the outer periphery of the support roll. Therefore, the circumferential speed changes and smooth suppression cannot be achieved.

In other words, after the pot sheet is pressed down on the floor, it is covered with a seedling box and turned over to raise the seedlings.If the pot sheet is not pressed down sufficiently, the turning operation cannot be performed smoothly, and beautiful seedlings cannot be produced. This means that it cannot be used for rice transplanters.

(Means for Solving the Problem) Therefore, the present invention provides a horizontal transfer table 3 for moving a storage box 4 fitted with a pot sheet 1 having a rectangular planar shape, and a floor pottery is placed in each pot 2 of the pot sheet 1.

This prevents the covering soil from leaking downward.

However, although the leading pot sheet 1 and the trailing pot sheet L are conveyed continuously without any gaps, the trailing pot sheet L
When the tip reaches below the first pressure roll 8 and the second pressure roll 13, the transfer speed decreases due to the resistance when being held between the first pressure roll 8 and the support roll η or the second pressure roll L3 and the support roll B. As a result, a gap is created between the leading pot sheet 1 and the trailing pot sheet 1 in front of the first pressing roll 8 and the second pressing roll 13, and the soil that falls from the gap is transferred to the support roll η, 23. Adheres to the outer periphery.

Therefore, the circumferential speed changes and smooth suppression cannot be achieved.

In the present invention, since the scrapers 24 and 25 are brought into sliding contact with the outer peripheral surfaces of the support rolls η and O, respectively, the support rolls η
, soil adhering to the outer peripheral surface of B is removed by scrapers 24 and 25.

Therefore, the bed earthenware in each pot 2 of the pot sheet 1 is sufficiently hardened, and when the seedling raising box is covered and turned over, the bed soil 3 in the pot z is not disturbed and the covering soil (9) does not leak, making it extremely Can be easily reversed.

(Effects) In the conventionally known Japanese Patent Application Laid-open No. 63-209504, a horizontal transfer table for transferring a storage box having a rectangular pot sheet fitted therein is provided with a floor surface that is supplied into each bolt of the pot sheet. A first pressing roll and a second pressing roll are provided in front of the bed soil supplying device to compress the floor in two stages, and a position directly below the first pressing roll and the second pressing roll is provided. describes a seeding device provided with a support roll that supports the entire width of the lower surface of the storage box. In the known suppression device, the leading pot sheet and the trailing pot sheet are conveyed continuously without any gaps, but when the leading edge of the trailing pot sheet reaches below the suppression roll, it is held between the suppression roll and the support roll. As the transfer speed slows down due to the resistance when rolling, a gap is created between the leading pot sheet and the trailing pot sheet on the front side of each suppression roll, and soil falls from the gap, and this soil is deposited on the outer periphery of the support roll. Attach to.

Therefore, the circumferential speed changes and smooth suppression cannot be achieved.

However, the present invention includes a bed soil supply device 5 that supplies bed soil 29 into each pot 2 of the pot sheet 1 on a horizontal transfer table 3 for moving a storage box 4 fitted with a pot sheet 1 having a rectangular planar shape. A bed soil 2 is provided in front of the above-floor supply device N5.
