提供されている。2. Description of the Related Art Conventionally, floor soil has been supplied to a nursery box and watered,
After sowing, a seeding machine that covers the soil or a soil-filling machine that supplies only the soil is used for the soil-feeding device that supplies or covers the soil in the seedling raising box. A brush is provided. The rotating brush is driven to rotate around the left and right axes to level the upper surface of the seedling raising box transported in the front-rear direction, so that a raised portion of the soil is formed near the front and rear walls in the seedling raising box. Japanese Patent Application No. 1-213345 discloses a soil leveling device which presses up the rising portion of the soil to level the upper surface of the soil.

The height can be freely adjusted so that the depth of the soil can be adjusted so that it can also be used as the soil and the soil. Therefore,
Correspondingly, the pressing member for pressing the rising portion of the soil of the soil leveling device must also be adjustable in height, but in the case of Japanese Patent Application No. 1-213345,
A pair of left and right mounting plates are provided on the upper side of the transfer path of the seedling box transferred in the front-rear direction, and these mounting plates are vertically movably supported by the support frame. Supports pressing members that press up the rising portion of the soil formed near the wall from above to level it, and protruding screw rods upward from each pressing member, supporting the upper parts of the left and right screw rods respectively An adjuster that penetrates the upper wall of the frame and is screwed to each screw rod from the upper end side is provided, and the adjuster is advanced and retracted to move the mounting plate up and down, thereby increasing the height of the holding member. It is configured to adjust.

置を提供することを目的とする。In the prior art, the adjusting member must be screwed in to adjust the height of the holding member. Therefore, the adjusting member cannot be quickly adjusted to the predetermined height. Rather, the height adjustment operation must be performed separately for the left and right, and there is a problem that the workability of the height adjustment operation of the holding member is poor. In view of the above problems, an object of the present invention is to provide a soil leveling device that can adjust the height of a holding member with one touch.
