When the rice transplanter is used for working, all the conical bearing disks 2 with seedlings are sequentially taken down from the vertical central tube 1 and are transported to a transplanting place, then one conical bearing disk 2 with the strip-shaped degradable seedling culture hole disks 3 is placed on the seedling release area of the supporting transverse shaft 6, then a plurality of conical bearing disks 2 with the strip-shaped degradable seedling culture hole disks 3 are sequentially placed on the seedling standby area of the supporting transverse shaft 6, after the placement is completed, the annular baffle 21 on the conical bearing disks 2 on the seedling release area is detached, the outer ring movable ends of the two strip-shaped degradable seedling culture hole disks 3 on the conical bearing disks are downwards freely under the action of gravity, then the movable end seedling culture pot bodies 31 of the two strip-shaped degradable seedling culture hole disks 3 are respectively clamped in the corresponding semicircular clamping grooves 7211 on the corresponding two synchronous belts 721 by manual assistance (at the moment, the two semicircular clamping grooves 7211 are not completely butted in place, so that the arc-shaped grooves 7211 on the two semicircular clamping grooves 7211 can not cut off the connecting belt before the two seedling-raising pots 31 are connected while the clamping effect on the two sides of the seedling-raising pots 31 is ensured, then the driving motor 724 is started, the driving motor 724 drives the synchronous belt 721 to rotate, the corresponding conical bearing disc 2 can slowly rotate and slowly rotate through the pulling effect of the strip-shaped degradable seedling-raising hole disc 3 in the rotating process of the synchronous belt 721, then the strip-shaped degradable seedling-raising hole disc 3 can be slowly conveyed into the synchronous belt 721, and in the moving process of the synchronous belt 721, when the two opposite semicircular clamping grooves 7211 are completely butted in place, the two cutting blades 7213 also cut off the connecting belt connecting the two seedling-raising pots 31 in the butting process, therefore, the seedling raising bowl bodies 31 are separated, the seedling raising bowl bodies 31 can continuously enter the corresponding semicircular clamping grooves 721 along with the continuous operation of the synchronous belts 721, when the seedling raising bowl bodies 31 move to the lower ends of the synchronous belts 721, the seedling raising bowl bodies 31 are separated from the semicircular clamping grooves 721 and directly fall into the grooves formed in the furrow openers 9, and the uniform planting of seedlings is realized by controlling the forward speed of the traction mechanism and the speed ratio of the seedling raising bowl bodies 31 continuously output by the synchronous belts 721.
After the strip-shaped degradable seedling culture hole trays 3 in the seedling release area all enter the semicircular clamping grooves 7211 on the synchronous belt 721, the empty conical bearing tray 2 is directly pushed into the empty tray placing area, then one conical bearing tray 2 with the strip-shaped degradable seedling culture hole trays 3 in the seedling placing area is placed into the seedling release area, the operation flow of clamping the seedling culture pot body 31 on the synchronous belt 721 by manual assistance is repeated, and then the seedling transplanting operation can be continuously realized.
In the present invention, "upper", "lower", "left" and "right" are relative positions used for convenience in describing positional relationships, and therefore, should not be interpreted as absolute positions as limiting the scope of protection.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
While the preferred embodiments and examples of the present invention have been described in detail, it will be apparent to those skilled in the art that the invention is not limited thereto, and that various changes and modifications may be made without departing from the spirit and scope of the invention.
