BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling feeding and packing device of a grass seedling cassette packing machine capable of automatically packing grass seedlings to be split into a cassette case for mounting a transplanter.

[0002]

2. Description of the Related Art Conventionally, a pair of conveyor belts are used to drop rush seedlings into a cassette case below and
In a rush seedling cassette packing machine that can be packed by a reciprocally movable seedling pressing body, as shown in JP-A-5-308820, while supplying rush seedlings into a seedling storage box by a pair of inclined conveyor belts. There is known a cartoning machine that can press the turfgrass seedlings into a carton by pushing them forward and backward by one of the conveyor belts.

[0003]

However, since the push-out tool moves back and forth in conjunction with the rotation of the conveyor belt, the push-out tool moves back after pressing the rush seedlings fed from the conveyor belt. At that time, the subsequent rush seedlings fed from the conveyor belt were caught in the pushing tool, and the posture of the rush seedlings was disturbed or stagnated, resulting in poor boxing performance.

[0004]

The first object of the present invention is to:
By solving such problems, the drive structure is configured so that the seedling feeding and seedling can be alternately carried out at a timely timing so that the seedlings can be effectively packed. In a grass seedling cassette packing machine that can be packed into a case by a reciprocating seedling pressing body, the rear end of the support rod of the seedling pressing body that moves back and forth inside the cassette case is The tip of the interlocking rod is connected to the tip of the rotating arm that is connected to the connecting body that moves back and forth and that extends from the drive shaft of one conveyor belt that interlocks with the other conveyor belt via the one-way clutch. At the same time, the rear end of the interlocking rod is connected to the connecting body, and the forward and backward movements of the connecting body enable the forward movement of the seedling pressing body and the driving of both conveyor belts alternately. It is constructed by the way.

A second object of the present invention is to enable the seedling pressing body to be effectively driven so that it can be horizontally reciprocated in the cassette case. Therefore, the rollers mounted on both sides of the support rod are provided. It is configured to be fitted on both rails extending in the horizontal direction.

A third object of the present invention is to enable the support rod of the seedling pressing body to be effectively driven so as to reciprocate horizontally in the cassette case. Therefore, the lateral width between both rails is set to the cassette case. The width is narrower than the lateral width of the above and is installed inside the cassette case of both rails.

[0007]

Therefore, when the connecting body is driven forward by the crank, the seedling pressing body moves forward to pack the grass seedlings to be fed from the conveyor belt while pressing the seedlings, but at the same time, the rotation While the arm is being rotated, the one-way clutch is turned off to stop the conveyor belt at a timely timing to stop the feeding of seedlings. When the connecting body is driven backward, the seedling pressing body moves backward. At the same time, when the one-way clutch is turned on, the conveyor belt is driven in a timely manner, and the sedge grass seedlings can be satisfactorily delivered so as to smoothly fall into the cassette case without being caught by the seedling pressing body.

If the rollers mounted on both sides of the support rod are fitted on the rails extending on both sides extending in the horizontal direction, the rollers roll along both rails in the horizontal direction. As a result, the seedling pressing body can be horizontally reciprocally driven, and the rush seedlings falling into the cassette case can be packed neatly without being disturbed.

If the horizontal width between both rails is made narrower than the horizontal width of the cassette case and both rails are installed inside the cassette case, the support rod is effectively driven so that it can reciprocate horizontally in the cassette case. can do.
