Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a soil supply device in a seeding device for a seedling box.

(Prior art) Conventionally, in a soil supply device consisting of a bucket conveyor that supplies sieved soil to a soil hopper of a soil supply device provided in a seedling box seeding device, the bucket a of the soil supply device is A vertical plate c approximately parallel to the rotary chain b to which the bucket a is attached, a bottom plate e projecting outward from the lower edge d of the vertical plate c, and attached to the sides of the vertical plate c and the bottom plate e. A structure formed by a side plate f is well known.

In addition, Japanese Utility Model Publication No. 51-143991 discloses that a bucket belt includes a vertical plate that is substantially parallel to a rotary chain to which the bucket is attached, a bottom plate that projects outward from the lower edge of the vertical plate, and a bottom plate that extends outward from the lower edge of the vertical plate. and a side plate attached to the side of the bottom plate, and the bottom plate is configured to be sloped so that substantially the same soil flows down following the vertical plate of the subsequent inverted bucket, and is received at a position where the tip of the bucket comes into contact with the bottom plate. A configuration is described in which a member is arranged, a supply gutter is provided below the receiving member, and the bucket conveyor is surrounded.

In addition, Utility Model Application Publication No. 54-41076 describes a belt conveyor in which a conveying body consisting only of a U-shaped bottom plate is attached to a rotary body, and a discharge port is formed at a position where discharge is discharged by rotational centrifugal force of the conveying body. has been done.

(Problems to be Solved by the Invention) The known device shown in FIG. 3 is arranged with a large gap i between the upper end g of the bucket a and the lower end h of the preceding bucket. When the bucket a rotates at its upper end and throws soil, there is a problem in that part of the thrown soil leaks from the gap i between the bucket a and the preceding bucket a, and is scattered on the floor below.

Furthermore, the conveyor described in Japanese Utility Model Application Publication No. 51-143991 is a bucket conveyor for powder and granules, and because it is fixedly installed on the floor, it cannot be used to supply soil to a seedling box sowing device.

Furthermore, since the entire bucket conveyor is surrounded by a frame, soil adheres to the inside of the frame, making maintenance difficult.

In particular, since the receiving member and discharge gutter are located far below the position where the bucket is reversed,
Soil is scattered and adheres to the rotating chain and receiving members.

Furthermore, the method described in Japanese Utility Model Application Publication No. 54-41076 also surrounds the entire belt conveyor, and in particular, the soil is ejected by the centrifugal force of the rotation of the conveying body, so the soil is often scattered.

(Means for Solving the Problems) Therefore, the present invention provides the left and right frames 2 and 3 of the bucket conveyor that endlessly rotates the bucket 9 in the vertical direction, and the upper parts of the left and right frames 2 and 3. A supply gutter 22 that supplies soil discharged from the provided bucket 9 to a soil hopper 25 of a soil supply device 24 provided in a seedling box seeding device, and a hopper 15 provided at the lower part of the left and right frames 2 and 3. and a soil supply device comprising a motor case 16 and transportation wheels 17, the bucket 9 includes a vertical plate 10 that is approximately parallel to the rotary chain 8 to which the bucket 9 is attached, and a vertical plate 10 that is outside the lower edge of the vertical plate 10 The upper end 13 of the vertical plate 10 of the bucket bag 9 and the lower end 14 of the vertical plate 10 of the preceding bucket bag 9 form a bottom plate 11 protruding in the direction, and a side plate 12 attached to the side of the vertical plate 10 and the bottom plate 11. The bottom plate 11 is configured to have an inclination so that substantially the same soil flows down following the vertical plate 10 of the subsequent inverted bucket 9, and the supply gutter 22 has a cross section with an open top surface. This is a soil supply device for a seedling box seeding device, which is formed into an upward U-shape and is installed at a position where the soil on the bottom plate 11 finishes flowing down.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a bucket conveyor section of a soil supply device, which has a pair of right and left frames 2 and 3,
Both ends of the upper rotating shaft 4 in the left and right direction are attached to the upper parts of the left and right frames 2 and 3, and the left and right frames 2 and 3 are connected to each other.
Both ends of a lower rotating shaft 5 in the left-right direction, which is a pair with the upper rotating shaft 4, are pivotally attached to the lower part of the rotating shaft. The upper rotating shaft 4
A sprocket 6 is fixed to the lower rotating shaft, sprockets are fixed to both sides of the lower rotating shaft, and a chain 8 is wound around the sprocket.

A plurality of buckets 9 are fixed to the outer periphery of the chain 8 to raise the sieved soil. The bucket 9 includes a vertical plate 10 substantially parallel to the chain 8, a bottom plate 11 connected to the lower edge of the vertical plate 10, and the vertical plate 10 and the bottom plate 1.
It is formed by a side plate 12 that is connected to the side of the main body 1.

The bottom plate 11 is formed at an angle of less than 90 degrees with respect to the vertical plate 10, so that when the bucket 9 is raised by the chain 8 and reversed at the upper end rotation part for throwing, it follows the vertical plate 10 of the reversed bucket 9. The slope will be constructed so that approximately the same soil flows down.

Thus, the bucket 9 has a lower end 14 of the vertical plate 10 of the bucket 9 and a vertical plate 10 of the subsequent bucket 9.
It is attached to the chain 8 without a gap between the upper end 13 of the chain 8 and the upper end 13 of the chain 8. That is, when the bucket 9 is lifted up by the chain 8, reversed and thrown at the upper end circulation part, some of the sieved soil in the bucket 9 is scattered toward the inside of the bucket conveyor 1, but this sieved soil is It is brought into contact with the vertical plate 10 of the bucket 9 to prevent it from entering the bucket conveyor 1.

Reference numeral 15 designates a soil supply hopper for sieving soil provided at the lower front sides of the left and right frames 2 and 3, 16 a motor case, and 17 transportation wheels.

Reference numeral 22 denotes a supply gutter at the upper rear side of the left and right frames 2 and 3, and the upper end of the feed gutter 22 is rotated so that soil on the bottom plate 11 of the bucket 9 flows down into the feed gutter 22 due to natural vibrations, etc. Install it in a position below the section. The lower end of the supply gutter 22 is formed so as to face above a soil hopper 25 of a soil supply device 24 provided above a horizontal transfer table 23 for transferring seedling boxes.

(effect) Next, we will discuss the effect.

When sieved soil is put into the soil supply hopper 15 and the motor is energized, the sprocket is rotated by the rotary shaft of the motor, the lower rotary shaft is rotated through the chain, and the chain 8 is rotated through the sprocket. rises to lift up the sieved soil in the soil supply hopper 15, and at the top position the bucket 9
is turned over and throws the sieve soil to the supply gutter 22,
2, the sieved soil is supplied into the hopper 25 of the bed soil supply device 24.

At this time, there was a considerable gap between the inverted buckets 9 and the buckets 9, so some of the fallen sieve soil entered between the buckets 9 and was scattered on the lower floor. . However, in the present invention, the bucket 9 is formed so that the lower end 14 of the vertical plate 10 and the upper end 13 of the vertical plate 10 of the subsequent bucket 9 are as close as possible without a gap.
This prevents the particles from falling downward from between the upper end 14 and the lower end 14 and being scattered.

(Effects) Conventionally, in a soil supply device consisting of a bucket conveyor that supplies sieved soil to a soil hopper of a soil supply device provided in a seedling box seeding device, the bucket a of the soil supply device is A vertical plate c approximately parallel to the rotating chain b to which the rotary chain b is attached, a bottom plate e projecting outward from the lower edge d of the vertical plate c, and a side plate f attached to the side of the vertical plate c and the bottom plate e. Those formed by the above are known.

However, as shown in FIG. 3, the known bucket cart is disposed with a large gap i between the upper end g of the bucket cart a and the lower end h of the preceding bucket cart a, so that the bucket cart a rotates at its upper end. There was a problem in that when the soil was moved and thrown, part of the thrown soil leaked from the gap i between the bucket a and the preceding bucket a and was scattered on the floor below.

However, the present invention has two frames 2 and 3 on the left and right sides of the bucket conveyor that endlessly rotates the bucket 9 in the vertical direction, and soil discharged from the bucket 9 provided on the upper parts of the left and right frames 2 and 3. from the supply gutter 22 that supplies the soil to the soil hopper 25 of the soil supply device 24 provided in the seedling box seeding device, the hopper 15 and motor case 16 provided at the lower part of the left and right frames 2 and 3, and the transport wheels 17. In the soil supply device, the bucket 9 includes a vertical plate 10 that is substantially parallel to the rotary chain 8 to which the bucket 9 is attached, a bottom plate 11 that projects outward from the lower edge of the vertical plate 10, and the vertical plate 10. 10 and a side plate 12 attached to the side of the bottom plate 11, and the upper end 13 of the vertical plate 10 of the bucket tote 9 and the lower end 14 of the vertical plate 10 of the preceding bucket tot 9 are formed with as little gap as possible, The bottom plate 11 is configured to be sloped so that substantially the same soil flows down following the vertical plate 10 of the subsequent inverted bucket 9, and the supply gutter 22 is formed in an upwardly U-shaped cross section with an open upper surface, and Since it is used as a soil supply device for the seedling box seeding device installed at the position where the soil on the bottom plate 11 finishes flowing down, the left and right frames 2 and 3 can be easily connected to the seedling box seeding device using the transport wheels 17. Since it can be transported, connection work can be done easily.

Since the bucket 9 is formed by a vertical plate 10, a bottom plate 11, and a side plate 12 attached to the sides of the vertical plate 10 and the bottom plate 11, the bucket 9 can be raised without scattering soil.

Since the bucket 9 is not enclosed, maintenance is easy.

The upper end 13 of the vertical plate 10 of the bucket tote 9 and the lower end 14 of the vertical plate 10 of the preceding bucket tot 9 are formed with as little gap as possible, so that soil is not scattered during reverse throwing.

Since the bottom plate 11 is configured to have an inclination so that substantially the same soil flows down following the vertical plate 10 of the subsequent inverted bucket 9, the lower surface of the bottom plate 11 serves as a soil guiding surface, and no special member is required. , the soil can be reliably delivered to the supply gutter 22.

Since the supply gutter 22 is formed in an upwardly U-shaped cross section with an open upper surface, the soil in the inverted bucket 9 flows down into the feed gutter 22 without clogging, adhesion, or other troubles.

Since the supply gutter 22 is provided at the position where the soil on the bottom plate 11 finishes flowing down, it prevents the soil on the bottom plate 11 from being scattered on the floor.

This effect is achieved.
