Description

[Detailed Description of the Invention] (Field of Industrial Use) The present invention relates to a soil-filling machine for dropping soil into a continuously-growing nursery box.

(Prior art) A soil-filling machine for dropping floor soil, covering soil, etc. into a nursery box, places the nursery box on a transport mechanism having a chain, a belt or rollers, while transporting this nursery box, The soil is dropped from the belt conveyor so that it is spread almost uniformly over the entire nursery box.The transport mechanism is continuously operated so that the soil can be continuously fed into many nursery boxes. , The nursery box is designed to pass through the soiling machine without stopping.

(Problems to be Solved by the Invention) In the above-mentioned conventional technique, since the nursery box passes under the belt conveyor at a constant speed, it is difficult to supply soil to the vicinity of the front wall, and the soil leveling in the subsequent process is further difficult. Even when the soil surface is leveled by the members, surplus soil is not supplied like in the vicinity of the rear wall.
This is a problem because it causes stock shortages.

(Means for Solving the Problem) The present invention uses a conveying chain with a claw for a conveying mechanism, and moves a nursery box relative to the conveying chain before the soil is supplied, so that the soil can be supplied to the vicinity of the front wall. At this time, the seedling raising box is braked to move relatively rearward, and thereby the seedling raising box is temporarily stopped with respect to the soil feeding belt conveyor, thereby making it possible to solve the problems of the prior art.

That is, the specific configuration for solving the problems in the present invention is
A conveyor chain 10 for mounting and conveying the seedling raising box 3, a conveying mechanism 4 having claws 11 at intervals longer than the length of the seedling raising box 3, and a soil supply mechanism for supplying soil from the belt conveyor 18 into the raising seedling box 3 being conveyed. 5, the soil feeding mechanism 5 is provided with forward shifting means 32 for moving the seedling raising box 3 at a speed higher than the conveying speed to bring it into contact with the front side claw 11. When the front end of the inside of the nursery box 3 reaches the soil drop position A, the rear side nail 11
Means for braking the seedling raising box 3 until it contacts the seedling raising box 3
40 is provided.

(Operation) The transport chain 10 with the claws 11 of the transport mechanism 4 always operates at a constant speed and transports the seedling raising box 3 placed between the claws 11.

The front shifting means 32 provided on the front side of the soil supply mechanism 5 moves the seedling raising box 3 on the transport chain 10 forward faster than the transport speed, abuts on the front side claw 11, and places the front and rear claws 11 between them. The nursery box 3 is located at the frontmost position.

Braking means provided near the soil drop position A of the soil supply mechanism 5
When the vicinity of the front wall 3a of the seedling raising box 3 reaches the soil drop position A, 40 abuts against the seedling raising box 3 to brake its movement, and the rear side nails
Only the nursery box 3 is stopped until 11 contacts the nursery box 3. As a result, the soil is dropped and supplied to the vicinity of the front wall of the seedling raising box 3 for the stop time.
