Description

[Detailed Description of the Invention] The present invention relates to a bed supply device for raising seedlings that can easily supply a predetermined amount of the bed to seedling boxes that are continuously transferred.

In the conventional device shown in FIG. 4, a bed machine 6, a rotary brush mechanism 7, etc. are arranged on the transfer mechanism 3, and feeding and leveling work on the floor is performed while the seedling raising boxes 2 are transferred continuously and without interruption. It will be done.

The amount of soil that can be put into the seedling raising box 2 on the bed is set, and if it is too small, it will cause problems in raising seedlings, so normally the amount of soil supplied from the bed machine 6 is larger than the set amount on the bed, and in order to make it the set amount. The rotating brush 30 of the rotating brush mechanism 7 sweeps and removes excess soil from the seedling growing box 2, and also levels the surface of the floor.

As the surplus soil is transferred to the subsequent seedling raising boxes 2, it accumulates and forms a pile, and after filling 5 to 6 seedling raising boxes 2 with soil, a gap must be provided and the surplus soil must be discharged from the rear edge 2a.

Conventionally, this gap formation is done artificially, which is a complicated work, and the excess soil from 5 to 6 boxes of the seedling growing box 2 is too much and falls off the side edge 2b of the seedling growing box 2, making it impossible to reuse it. Sometimes it becomes.

In view of these conventional problems, the present invention increases the transfer speed of the seedling nursery box while it is passing through the rotating brush mechanism, and automatically creates a gap between the seedling nursery boxes and the following seedling nursery boxes to raise the seedlings. An object of the present invention is to provide a seedling raising bed soil supply device configured to discharge surplus soil from box to box.

A feature of the present invention to achieve this object is an above-the-floor feeding device for seedlings in which a bed machine and a rotary brush mechanism are disposed on a transfer mechanism for continuously placing and transferring seedling boxes, wherein the transfer mechanism includes a rotary brush mechanism. In order to form a soil removal gap between the seedling growing box passing through the mechanism and the succeeding seedling growing box, the rotating brush mechanism is set at a speed higher than the transfer speed of the first transfer section that sends the seedling growing box through the bed soil machine to the rotating brush mechanism. The point is that the second transfer section that allows the water to pass through is set at a high speed.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 indicates the entire seedling-raising seeding device, and this seeding device 1 is roughly divided into a transfer mechanism 3 for mounting and conveying a seedling-raising box 2, and a support frame 4 that supports this transfer mechanism 3. ,
It has a bed machine 6, a rotary brush mechanism 7, a watering machine 8, a seeding machine 9, and a soil covering machine 10, which are placed on the support frame 4 and straddle the seedling box transfer path 5 of the transfer mechanism 3.

1 to 3, the support frame 4 has two parallel U-shaped cross-sectional frames 11 and a plurality of support legs 12, and one support leg 12 has a transfer mechanism 3. A motor section 13 is attached.

The transfer mechanism 3 includes the motor section 13, a large number of rollers 14 pivotally supported at intervals on the frame 11, and the motor section 13.
from all rollers 14 to sprockets 15 for transmitting power;
It consists of a chain 16, a roller shaft 17, etc.

These sprockets 15, chain 16, etc. are housed in grooves in the frame 11 having a U-shaped cross section.

The floor earth machine 6 has a belt conveyor 19 parallel to the transfer route 5 and a hopper 20 above the belt conveyor 19.
9 receives power from the transfer mechanism 3 through a chain transmission means 21, and is configured to feed the seedlings on the floor in synchronization with the movement of the seedling box 2.

Reference numeral 22 denotes a gate member which adjusts the gate 23 formed between the belt conveyor 19 and the amount on the floor to be supplied.

The rotating brush mechanism 7 is located in the front of the bed machine 6 in the direction of transporting the seedling box, and cleans the excess soil to a predetermined amount while leveling the upper surface of the floor placed in the seedling box 2.

This rotary brush mechanism 7, the above-mentioned bed machine 6, and the transfer mechanism 3 constitute a bed soil supply device 24.

The rotating brush mechanism 7 includes left and right side plates 26 formed of U-shaped members.
27 and a connecting plate 28 connecting the upper ends of the frame body 29, which has a substantially U-shape in plan view; a rotating brush 30 whose both ends are supported by the frame body 29; It has a pair of left and right height adjustment members 31 provided on the connecting plate 28, and the lower part of the frame 29 is rotatably supported on a roller shaft 17, and the roller shaft 17 and the rotating brush 3
0 and a chain 32 and sprocket 33°34
A chain transmission means 35 is provided, which is arranged in the right side plate 21.

The height adjustment member 31 is a bolt screwed onto the connecting plate 28.
Its lower end is in contact with the upper surface of the frame 11, and by turning this bolt, the upper part of the tilted frame 29 can be adjusted up and down, and the height of the rotating brush 30 relative to the seedling box 2 can be adjusted. can.

36 is a locking wing nut screwed onto the height adjusting member 31.

In the floor feeding device 24, the transfer mechanism 3 is divided into a first transfer section 38 and a second transfer section 39, and the second transfer section 39 has a transfer speed of the seedling box 2 faster than the first transfer section 38. It's fast.

Among the plurality of sprockets 15 forming the transfer mechanism 3,
The two sprockets N5a have a smaller diameter than the others, and therefore rotate at a higher number of rotations than the other parts, and the space between these sprockets NSa forms the second transfer section 39.

The first transfer section 38 is formed to pass through the bed earth machine 6 and reach the rotary brush mechanism 7, where the seedling raising boxes 2 are continuously connected and placed and transferred, and are supplied to the seedling raising boxes 2 from the belt conveyor 19. There is no possibility that soil will fall from between two successive seedling boxes.

A second transfer section 39 is formed from the position where the tip of the seedling raising box 2 after being supplied on the floor contacts the rotating brush 30 to just before the irrigation machine 8, and the seedling raising box 2 that has reached the rotating brush mechanism 7 transfers the subsequent seedlings. Since it moves faster than box 2, a gap B is formed between them.

The floor inside the seedling growing box 2 is smoothed by a rotating brush 30, and excess soil is cleaned and discharged from the rear edge 2a of the seedling growing box 2 through a gap B, and stored in a dumped soil receiving box 40.

The height of this bed soil is adjusted by the height of the rotating brush 30 by the height adjusting member 31.

Instead of making the two sprockets 15a smaller in diameter than the others, the two sprockets 15b shown in FIG. 38, and the first transfer section 38 can be made to have the same speed as the seeding machine 9 and the soil covering machine 10.

In addition, when the device is configured to simply supply the seedling raising box 2 with food on the floor, one sprocket N 5a or 15b with a small diameter or a large diameter is provided to reduce the speed of the first transfer section 38 compared to the second transfer section 39. Just leave it there.

Moreover, even if the roller 14 of the second transfer section 39 is formed to have a larger diameter than the rollers of other parts, or only the second transfer section 39 is driven at high speed by a separate drive source, it is possible to raise seedlings during soil leveling. A gap B can be formed at the rear of the box 2.

The irrigation device 8 has a watering plate 43 pivotably supported below a water supply pipe 42 communicating with a water pipe. Supply the required amount of water approximately evenly.

The seeding machine 9 includes an outer frame 44 fixed to the frame 11, an inner frame 45 arranged vertically movably within the outer frame 44, and a seed hopper 46 and a feed roll 47 arranged on the outer frame 44. The supporting upper frame 48 and the seeding roll 49 supported by the inner frame 45,
It includes a rotating brush 50, a surplus paddy discharge body 51, and a drive mechanism 52 for driving the seeding roll 49, the rotary brush 50, the surplus paddy discharge body 51, and the feeding roll 47.

The soil covering machine 10 has the same structure as the floor machine 6, and drives a belt conveyor 54 from the transfer mechanism 3 via a chain transmission means 53, and supplies the soil in the hopper 55 onto the seeds in the seedling box 2 through the gate 56. Cover with soil.

According to the present invention described in detail above, the transfer speed of the seedling growing box 2 passing through the rotating brush mechanism 7 is made higher than that of the seedling growing box before reaching the rotating brush mechanism I, so that there is a gap between the two due to the speed difference. B is automatically formed, so excess soil from the bed soil supplied to the seedling raising box 2 is discharged from the gap B for each box, and too much surplus soil spills from the side edge 2b of the seedling raising box 2. Therefore, a normal amount of seedlings on the floor can always be supplied to the seedling growing box 2.
