[0006]

An embodiment of the present invention will be described with reference to the drawings.
Is a soil covering or bed soil supplying device of the seeding device, and is provided above the transfer table 2 for transferring the seedling raising box. The soil covering or floor soil supplying device 1 has a publicly known structure, and has a supplying hopper 3 provided at an upper part thereof, and a feeding belt 4 and the like which is provided below the supplying hopper 3 and which rotates in parallel with a transfer direction of the seedling raising box. Reference numeral 5 denotes an operation unit of the soil cover or floor soil supply device 1.

Therefore, the soil covering or floor soil supplying device 1
A soil supply device 10 for supplying soil to the supply hopper 3 is provided on the side portion of. The soil supply device 10 is provided with a pair of frames 11, 11 in parallel with the transfer direction of the nursery box.
A bucket conveyer 12 is provided between Nos. 1 and 11, and a soil supply hopper 13 is provided below the No. 11.

The bucket conveyor 12 has a frame 1
An upper rotary shaft 14 parallel to the transfer direction of the nursery box is attached to the upper part of the Nos. 1 and 11, and a lower rotary shaft 15 is attached to the lower part,
A sprocket 16 is fixed to the upper rotary shaft 14 and a sprocket 17 is fixed to the lower rotary shaft 15, and a chain 18 is provided between the sprocket 16 and the sprocket 17.
Is wound around the chain 18, and a plurality of buckets 19 for raising the soil are fixed to the outer periphery of the chain 18.

The upper end portion A of the bucket conveyor 12 is provided so as to face the front and rear side portions B of the supply hopper 3. At the upper end portion A of the bucket conveyor 12, the bucket conveyor 12 side is high and the soil cover or the floor soil supply device 1
The bottom plate 20a and the upright plate 20 which are inclined lower toward the side
and a guide gutter 21 that supplies the soil discharged from the upper end portion A to the front and rear side portions B of the supply hopper 3 on the lower surface of the bottom plate 20a on the front side.

The guide gutter 21 is provided with a mounting portion 22 having the same inclination as the bottom plate 20a of the guide cover 20, a steeply inclined guide plate 24 connected to the mounting portion 22, and parallel to the transfer direction of the nursery box. The guide plate 25 is inclined at one side in the transfer direction and becomes lower as it goes to the other side, and an upright wall 26 is provided continuously with the edge of the guide plate 25.
Is brought into contact with the lower surface of the bottom plate 20a and is attached by screws 23.

The guide gutter 21 may be configured such that the space between the upright wall 26 and the guide plate 24 becomes narrower as it goes downward.

Although the soil thrown at the upper end A of the bucket conveyor 12 directly enters the guide gutter 21, the soil that has not entered the guide gutter 21 directly enters the bucket conveyor 12 as described above. Since it is prevented by the cover 20, the guide cover 20 is formed integrally with the guide plate 25, and the guide gutter 21 is directly provided on the frames 11 and 11, and the guide cover 20 may be omitted. It suffices that the soil raised by can be supplied to the supply hopper 3 of the soil supply device 1 in a direction parallel to the transfer direction of the nursery box.

Further, when the throwing angle of the bucket 19 is set to an angle close to vertical, the soil falls naturally and the flight distance becomes the same due to the difference in size of the clod, so that the soil falls in the guide trough 21 at the same point. It falls and the mixing ratio becomes even. Reference numeral 27 is an operation box, and 28 is a motor mounted directly or indirectly on the upper rotary shaft 3.

[0014]

[Operation] Next, the operation will be described. When the soil is fed into the soil supply hopper 13 and the motor 28 is energized, the rotation shaft of the motor 28 rotates the upper sprocket 16 and the lower sprocket 17 to rotate the chain 18, so that the bucket 19 is Ascend to lift the sieve soil in the soil supply hopper 13, and at the uppermost position, the bucket 19 is inverted to throw the sieve soil in a direction intersecting with the transfer box 2 transfer direction of the seedling box, and the soil is guided to the guide trough 21. It enters and is supplied from the guide gutter 21 into the supply hopper 3 of the soil cover or floor soil supply device 1.

In this case, if a supply gutter is provided at the upper end portion A of the bucket conveyor 12 in the spouting direction of the bucket 19 as in the conventional case, the spoiled soil flows down on the well-known supply gutter to the supply hopper 3. When you enter, a large mass of clod is far away,
The soil mass with a small mass will fall nearby, and it will not be possible to supply it evenly in the width direction of the nursery box, but the guide trough 21 is parallel to the steep guide plate 24 and the nursery box transfer direction, Since it is composed of the guide plate 25 which is inclined at one side in the direction and becomes lower toward the other side, the soil thrown at the upper end portion A of the bucket conveyor 12 is mixed with the clods having different masses. Even if the mass of large mass and the mass of small mass are separated, the mass enters into the guide trough 21 before the inertia acts, and is immediately guided by the inclination of the guide plate 25 to flow down in the direction parallel to the nursery box transfer direction. Since it starts, the feeding hopper 3 with the mixing ratio of the size of the soil block being equal in the width direction of the guide gutter 21
Run down to.

Then, the feed hopper 3 is fed from inside the guide gutter 21.
When entering, the large mass of mass falls far away from the lower end of the guide gutter 21 and the small mass of mass falls close to it, but it is uniform when seen from the width direction of the supply hopper 1, so it is supplied to the nursery box. When a large mass of soil is supplied to the bottom of the nursery box, and a small mass of soil is supplied to the upper layer of the nursery box, the width direction of the nursery box becomes even and eventually evenly over the whole. Can supply soil.

If the guide gutter 21 is constructed such that the space between the upright wall 26 and the guide plate 24 becomes narrower as it goes downward, the soil that has entered the guide gutter 21 will be mixed in the width direction while flowing down. In addition, the mixing ratio of the soil mass in the width direction becomes even.

[0018]

[Effect] According to the present invention, a soil feeding device having a transfer table 2 for laterally transferring a nursery box, a supply hopper 3 provided above the transfer table 2, and a feeding belt 4 rotating in parallel with the transfer direction of the nursery box. 1 and a bucket conveyor 12 having a bucket 19 provided between a pair of vertical frames 11 and 11 to endlessly rotate in a direction intersecting with the seedling raising box transfer direction to raise soil, and the frames 11 and 11. It consists of the soil supply hopper 13 provided at the lower position,
In the upper position of 1, so that the bucket 19 supplies the soil thrown at the upper end so as to intersect with the transfer direction of the nursery box to the supply hopper 3 in a direction parallel to the transfer direction of the nursery box.
Since the soil supplying device is provided in the seeding device provided with the guide gutter 21 in which the one side is high and the other side is inclined in parallel with the nursery box transfer direction, the soil irradiated at the upper end of the bucket conveyor 12 is Even if the masses with different masses are mixed, the masses with a large mass and the masses with a small mass enter the guiding trough 21 before the inertia acts, and are immediately guided by the inclination of the guiding plate 25 to raise seedlings. Since the flow-down is started in the direction parallel to the box transfer direction, when the flow-down starts toward the supply hopper 3 with the mixing ratio of the size of the soil mass being uniform in the width direction of the guide gutter 21 and enters the supply hopper 3 from inside the guide gutter 21. , The mass of large mass falls far from the lower end of the guide gutter 21 and the mass of small mass falls close to it, but it is uniform when seen from the width direction of the supply hopper 1, so when supplied to the nursery box. In addition, a large mass of soil grows. Is supplied to the bottom of the box, a small consisting clods of mass only be supplied to the upper layer of the nursery box, the width direction of the nursery box becomes uniform, an effect that it uniformly supplied soil throughout eventually. According to the present invention, the guide gutter 21 includes a guide plate 25 and a guide plate 2 which are inclined at one side and at the other side.
5, the standing wall 26 and the guide plate 24 standing upright on both sides are formed into a U-shaped cross section, and the distance between the standing wall 26 and the guide plate 24 is made smaller toward the lower side to provide a soil supply device in a sowing device. Therefore, the soil that has entered the guide trough 21 mixes in the width direction while flowing down, and the mixing ratio of the size of the soil mass in the width direction becomes even.
