Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a seedling growing box conveying device.

(Conventional technology) In a seedling seeding seeding machine, a soil-filling device, a seeding device, a watering device, etc. are installed on a conveyor, and the conveyor continuously transports the seedling-growing boxes at a constant speed while pouring soil (bedding soil, covering soil). , sowing, watering, and other necessary work.

(Problem to be solved by the invention) In this type of seedling-raising seeding machine, the transport speed of the seedling-raising box is constant when the seedling-raising box passes under the soil-filling device, seeding device, watering device, etc. Moreover, it is necessary that there be no gaps between the front and rear seedling boxes.

However, conventional conveyors are designed to transport seedling boxes at a constant speed over the entire length from the supply side to the take-out side, so when feeding the seedling boxes onto the conveyor, The disadvantage is that it becomes difficult to take out the seedling box.

In other words, since the conveyor speed is constant,
Workers on the supply side must place seedling boxes on the conveyor so that there are no gaps between the boxes before and after the boxes, and workers on the pick-up side must place the seedling boxes on the conveyor so that there are no gaps between them. There is no space to put it in, so it is difficult to take it out.

In view of these conventional problems, it is an object of the present invention to make it possible to place seedling growing boxes with gaps on the supply side, and to create gaps between the seedling growing boxes on the take-out side.

(Means for Solving the Problem) As a means for that purpose, the present invention arranges a soil-filling device 3 and a seeding device 5 singly or in combination on the main conveyor 2, and transports the seedling boxes 1 by the main conveyor 2. In this system, auxiliary conveyors 7 and 8 whose conveying speed is higher than that of the main conveyor 2 are provided at both ends of the main conveyor 2 in the conveying direction.

(Function) When the seedling growing box 1 is placed on the auxiliary conveyor 7 on the supply side, since its conveyance speed is higher than that of the main conveyor 2, the succeeding seedling growing box 1 comes into contact with the preceding seedling growing box 1, and therefore the gap Even if the seedling boxes 1 are placed on the main conveyor 2 with a gap between them, the seedling growing boxes 1 can be conveyed without any gaps.

On the other hand, on the take-out side, since the conveyance speed of the auxiliary conveyor 8 is high, the seedling growing boxes 1 are transported quickly, creating a gap between the preceding seedling growing box 1 and the succeeding seedling growing box 1.

(Example) Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. In Figs. 1 and 2, 1 is a seedling box;
is a main conveyor that conveys the seedling growing box 1 at a constant speed. On this main conveyor 2, a soil digging device 3, a leveling device 4, a seeding device 5, and a watering device 6 are installed. Speed auxiliary conveyors 7, 8 are provided.

The main conveyor 2 includes a pair of left and right main frames 9 arranged in parallel, a number of rotating shafts 10 rotatably inserted and supported between the pair of main frames 9, and a pair of left and right rotating shafts attached to each of the rotating shafts 10. The rubber roll 11 is supported by a pillar 12. The rotating shafts 10 are interlocked and connected to each other via a chain-type or similar winding transmission mechanism 13 at one end. Note that the main frame 9 has a U-shaped cross section,
The transmission mechanism 1 is wrapped around the inside of the main frame 9 on one side.
Contains 3.

The auxiliary conveyors 7 and 8 include a pair of left and right auxiliary frames 16 and 17 that are foldably pivoted upward by hinges 14 and 15 on the top surface of the tip of the main frame 9.
and the tip of the main frame 9 and the auxiliary frame 16,
17 Rotating shafts 1 rotatably inserted and supported at the tips of each
8, 19 and rotating shafts 20, 21, V pulleys 22, 23, 24, 25 attached to these rotating shafts 18, 19, 20, 21, and these V pulleys 2
V-belt 2 wrapped around 2, 23, 24, 25
6, 27. The rotating shafts 18, 19 are interlocked with the rotating shaft 10 via winding transmission mechanisms 28, 29, and V pulleys 22, 23, 2
4 and 25 have a slightly larger diameter than the rubber roll 11 so that the conveyance speed on the side of the auxiliary conveyors 7 and 8 is slightly faster than on the side of the main conveyor 2. The rotating shafts 18 and 19 on the side of the auxiliary conveyors 7 and 8 are arranged so that there is a distance L that is at least the length of 11 seedling boxes between the soil filling position of the soil filling device 2 and the watering position of the watering device 5. It is set in. In addition, V belt 2
6 and 27 are supported from below by a support rod 30 in the middle.

The soil filling device 3 serves both as soil filling and covering soil, and a hopper 3 is installed between the side plates 31 on the main frame 9.
2 and a feeding belt 33, the feeding belt 33 is connected to the rotating shaft 10 via a winding transmission mechanism 34.
is linked to. The leveling device 4 is equipped with a rotating brush 35 between the tips of a pair of left and right swinging arms 34, and is configured to level the bed soil placed in the seedling growing box 1 by the soil insertion device 3.

The seeding device 5 is supported by a side plate 36 on the main frame 9, and has a hopper 37 and a feed roll 38.
and has. The feeding roll 38 is a winding transmission mechanism 39
It is operatively connected to a motor 40 mounted on the side plate 36 via a clutch and a clutch. The motor 40 is of a forward/reverse rotation type, and is interlocked with the rotating shaft 10 via a winding transmission mechanism 41. Therefore, the main conveyor 2, auxiliary conveyors 7, 8, and soil insertion device 3 can be switched between forward and reverse directions. It is. The watering device 6 is for sprinkling water onto the soil floor of the seedling raising box 1.

During the work, while transporting the seedling raising box 1 in the direction of arrow A using the auxiliary conveyor 7, main conveyor 2, and auxiliary conveyor 8, fill the seedling raising box 1 with bed soil, level the bed soil, and then move the bed. Sprinkle water on the soil. That is,
When the motor 40 is rotated forward, the conveyance direction becomes the direction indicated by arrow A, so that empty seedling boxes 1 are placed on the auxiliary conveyor 7.
, the seedling raising box 1 is transported in the direction of arrow A. Then, the top soil of the seedling raising box 1 is put in with the soil pouring device 3, and after the bed soil is leveled with the rotating brush 35 of the leveling device 4, water is sprinkled on the bed soil with the watering device 6.

When the seedling growing boxes 1 are sequentially placed and fed on the auxiliary conveyor 7, the conveyance speed of the auxiliary conveyor 7 is faster than that of the main conveyor 2, so a gap is created between the seedling growing boxes 1a and the preceding seedling growing boxes 1a as shown in FIG. Even when the next seedling growing box 1b is placed, the subsequent seedling growing box 1b is quickly moved and comes into contact with the previous seedling growing box 1a, so that the seedling growing boxes 1 can be continuously supplied. Moreover, since there is a distance L between the auxiliary conveyor 7 and the soil filling position of the soil filling device 3, which is more than 11 seedling boxes, the conveyance speed of the seedling boxes 1 does not change when soil is poured. Enables uniform soil penetration.

After watering, the seedling growing boxes 1 are sent from the main conveyor 2 to the auxiliary conveyor 8, and then taken out and stacked on the side as appropriate. In this case, since the conveyance speed of the auxiliary conveyor 8 is high, when the seedling growing box 1 is transferred onto the auxiliary conveyor 8, it is sent quickly, creating a gap between it and the following seedling growing box 1, and thus The worker on the extraction side can easily take out the seedlings by placing his/her hands on both the front and rear ends of the seedling raising box 1. Further, since there is a distance L between the seedling box 1 and the watering device 6, the conveyance speed of the seedling growing box 1 does not change during watering, and watering can be uniformly performed.

At the time of sowing, the motor 10 is reversed to supply seedling boxes 1 from the auxiliary conveyor 8 side, and the main conveyor 2,
While conveying in the direction of arrow B via the auxiliary conveyor 7, seeds are sown onto the bed soil by the seeding device 5, and covered with soil by the soil insertion device 3. In this case as well, the seedling growing box 1 can be easily supplied and taken out as described above.

The main conveyor 2 and the auxiliary conveyors 7 and 8 may be either rubber roll type or belt type, and are not limited to the embodiments.
