Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention relates to a germination / seedling raising device, and more specifically, to a germination device in which a plurality of seedling raising boxes that have been soil-filled, seeded and covered with soil are kept at an appropriate room temperature. The seedlings are stored in a container and germinated (also referred to as germination), and the germinated seedlings are grown to a predetermined length, and especially when germinated, the roots prevent the seeds from being pushed up and floating on the soil cover surface. It relates to germination and seedling raising equipment.

[0002]

Background of the Related Art and its Problems Conventionally, germination and seedling raising were performed in separate facilities. Therefore, in the germination stage, a plurality of nursery boxes are stored in a stacked state in which the upper nursery box bottoms are stacked on each other so as to close the opening of the lower nursery box,
Germinate using a germination device (generally called a germinator) configured to maintain the temperature and humidity suitable for germination,
Then, in the seedling raising period after the germination period has ended, the seedling raising boxes that have been taken out from the germination period are carried to a greenhouse such as a greenhouse that is kept at a temperature and humidity suitable for raising seedlings, and the seedling raising boxes that have been carried in are kept. The seedlings in the nursery box that sprouted in a vertical and horizontal row in the greenhouse were grown to a suitable length for seeding (transplanting) with a rice transplanter.

Therefore, conventionally, after the germination period has ended,
It was necessary to take out the seedling raising boxes from the germination device, carry them to a greenhouse such as a greenhouse, and arrange the seedling raising boxes in a vertical and horizontal row in the greenhouse, which requires a great deal of labor and time. Moreover, since the germination period is generally said to be completed in 2 to 3 days, the conventional germination device is allowed to play after being used for 2 to 3 days, and the germination device is not effectively used. At the same time, a greenhouse facility such as a greenhouse must be purchased and prepared separately from the germinator, which causes a problem of enormous cost for facility investment and maintenance.

Recently, a pair of left and right shelving units, in which a plurality of box mounting shelves for supporting and supporting a plurality of seedling raising boxes at appropriate intervals have been developed, have been developed. By attaching the seedlings, germinated seedlings can be stored in the germination device at intervals so that the seedlings can be grown to an appropriate length. However, since this shelf unit is not used during the germination period, it is removed from the germination device during the germination period, and after the germination period is over, the bottom of the upper nursery box closes the opening of the lower nursery box. All of the nursery boxes that were stored in a stacked state on top of each other had to be taken out from the device once, and
After mounting the shelf unit in the device, it is necessary to carry out the putting in and out work of storing the seedling raising box in the device again while supporting and supporting the seedling raising box on each box mounting shelf of the shelf unit, which requires a great deal of labor and time. I have to spend.

Incidentally, unless rooting is prevented in the germination stage, the rooting becomes poor and the germination of seedlings cannot be expected. Therefore, the prevention of rooting at the germination stage is important for the growth of strong roots and the improvement of rooting to grow healthy seedlings.

[0006]

[Problems to be Solved by the Invention] The present invention has been made in view of such conventional circumstances, and aims to prevent rooting at the germination stage and to grow the sprouted seedlings to a seedling length suitable for rice planting (transplanting). It is an object of the present invention to provide a germination / seedling raising device which can be carried out until the seedling raising period, and which is improved so that the root-preventing lid does not get in the way when the seedling raising box is put in or taken out.

[0007]

[Means for Achieving the Object] The technical means taken by the present invention to achieve the above-mentioned problems is to provide a plurality of nursery boxes at appropriate intervals in the vertical direction in an apparatus frame kept at an appropriate room temperature. In addition to arranging the box mounting shelves that are placed in multiple stages and supporting in several rows in the front-rear direction in each step, at the intervals, a root-prevention lid that closes the opening of the seedling raising box is provided between the box mounting shelves in each step. ,
It is arranged so that it can be moved up and down by being linked to an elevating mechanism, and the raising prevention lid of each stage is lowered by the elevating mechanism to close the opening of the nursery box of each stage to prepare for the germination stage and raise it to each stage. It is constructed so that it can be removed from the opening of the seedling raising box to prepare for the seedling raising period, and further the above-mentioned root-prevention lid is connected and supported by the elevating mechanism via the pair of left and right lid receiving rails, and it is placed back and forth on the box mounting shelves at each stage. It is characterized in that it is configured to be slidable in the front-rear direction so as to extend across the openings of the nursery boxes which are supported and supported in several rows in the direction.

[0008]

By lowering the root-prevention lids 4 ... of each stage, the openings of the seedling raising boxes 2 ... that are placed on the box-mounting shelves 3 ... of each stage and stored in multiple stages are closed to prepare for the germination stage, and then raised. As a result, the seedlings 6 in the seedling raising box 2 that have germinated by removing the rooting prevention lid 4 from the opening of each seedling raising box 2 are raised to a seedling raising length (plant height) of about 7 to 9 cm suitable for rice planting. It is configured so that it can be equipped.

The apparatus frame 1 is installed on a heat-insulating mat 7 and the heat-insulating cover 8 covers the ceiling and the entire circumference, so that a plurality of nursery boxes 2 ... A germination / seedling chamber 9 of a size having an opening height that can be stored, a depth that can be stored in several rows in the front-rear direction in each stage, and an opening width that can be stored in several rows on the left and right sides is framed on the upper side, and its bottom portion is formed. The temperature and humidity of the germination / seedling room 9 are configured as a framework 11 for heating and humidifying according to the germination period and the seedling raising period, and a space 11 for storing and storing a heater 10 for humidifying. The germination / seedling room 9 is kept at the optimum temperature and humidity suitable for germination during the germination period by the heater 10 for heating and humidifying the bottom space 11, and at the optimum temperature and humidity suitable for seedling during the seedling period. It is supposed to be kept.

The box-mounting shelves 3 are arranged in the front-rear direction (the direction in which the nursery box is taken in and out of the machine frame) by abutting the long-side opening edges of the nursery box 2 formed in a shallow rectangular shape in a plan view. Equipment for constructing germination / seedling chambers 9 in which frames are erected at intervals in the front-rear direction that can be stored in a state of being supported and arranged in a number of rows. The pair of left and right shelf frames formed on the front and rear struts 1a are opposed to each other at the same height level in the opening width direction of the germination and seedling raising room 9 at the long side width intervals of the seedling raising box 2 as shown in the figure. By attaching by screwing, welding, etc., the germinated seedlings 6 can be arranged in the opening height direction at a vertical interval so that the germinated seedlings 6 can be grown to a seedling-growing length suitable for rice planting. Multi-stage equipment can be installed in the machine frame 1.

However, the box-carrying shelves 3 have a plurality of seedling raising boxes 2 with the short side box bottoms of the seedling raising boxes 2 placed on the left and right shelf frames.
Are fixedly mounted in the machine frame 1 so as to support a plurality of vertical rows with the long side opening edges abutting against each other in the front-back direction and in a vertical row with vertical intervals for raising seedlings. To do.

In the embodiment, the left and right front and rear struts 1a and one of the pair of left and right shelves are mounted on the left and right intermediate struts 1b which are erected between the struts 1a at intervals of the long side width of the nursery box 2. By installing as shown in Fig. 3, the box mounting shelves 3 are installed in several rows (two rows in the figure) in the opening width direction of the germination and seedling raising room 9, and a plurality of seedling raising boxes 2 ... Instead, it is fixedly arranged so that it can be received and stored in several rows in the lateral direction with the right and left intermediate support columns 1b as a boundary.

Incidentally, the seedling-growing length suitable for planting rice seedlings 6 refers to the length of the transplanted seedlings 6 that emerges from the water surface without being submerged in water. Therefore, in general, 14 to 16 germinated seedlings 6
The seedlings are planted after being grown to a seedling length of about cm. However, recently, the transplanted seedlings 6 have tended to be transplanted to milk seedlings, which can grow relying on the nutrients remaining in the seeds for a while without being affected by water and weather. In other words, there is a tendency to plant rice when seedlings 6 have grown to about 7 cm (at least 6 cm) where they can grow depending on the nutrients in the seed even after planting rice. As a result, even if the transplanted seedling 6 is submerged in water, it is said to grow vigorously without dying. Recently, a seedling raising method for raising a seedling length of about 7 to 9 cm has been adopted. ing.

Therefore, in this embodiment, the vertical intervals of the box mounting shelves 3 on which the seedling raising boxes 2 are placed are set so that the seedling raising length is 7 to 9 cm.
Considering the stand-by space for rising of the rooting prevention lid 4 that approaches the box bottom of the upper seedling raising box 2, for example, a larger spacing than that of the upper seedling raising box 2, and a vertical row in the germination and nursery room 9 at a spacing L of about 9 to 12 cm. The fixing is arranged in multiple stages. And the sprouted seedling 6

It is supported by the elevating mechanism 5 via 12 and is arranged between the box mounting shelves 3 at each stage, so that it is supported by the left and right lid receiving rails 12 and slidable in the front-back direction.

However, the root-prevention lid 4 has left and right lid receiving rails so that the divided lids 4a, which are divided into several pieces, overlap each other.
12 Slide the top toward the back of the machine frame 1 to reduce it (state of Fig. 8 (b)), and divide the overlapping lids 4a into left and right lid supports so as to unfold the overlapping state. The rail 12 is slid toward the front side of the apparatus frame 1 and independently supported on the left and right lid receiving rails 12 to be in an extended state. In other words, when it is in the expanded state, it becomes the size of the state in which the openings of the seedling raising boxes 2 which are arranged and supported in several rows in the front-rear direction on the box placing shelf 1 are closed (see FIG. 8 (a)). Status).

Among the divided lids 4a, the divided lids which are located on the front side of the apparatus frame 1 in a slid and extended state (the divided lids which are located at the uppermost stage in the contracted state where they overlap each other) 4a
By providing the grip portion for sliding on the upper surface of the front edge or the front end thereof, the sliding operation, particularly the operation at the time of extending the slide, becomes simple. Further, except when the number of the split lids 4a is two, the slide lids 4a are slid by providing appropriate latching means for latching and linking with each other on one or both of the overlapping edge portions as shown in the figure in a slid and extended state. The second split lid 4a may be slid on the first split lid 4a by sliding the first split lid 4a toward the front during the extension operation. That is, it is preferable that the first divided lid 4a is pulled and the second and subsequent divided lids 4a slide.

The elevating mechanism 5 is frame-structured at a height ranging from the lowermost box-carrying shelf 3 to the uppermost box-carrying shelf 3, and the root-preventing lids 4 of the respective stages are provided via a pair of left and right lid receiving rails 12. And an elevating frame 5a that slidably supports in the front-back direction, and a plurality of arm rods that support the elevating frame 5a at its lower end side.

The screw-type lifting device 5b is a screw-type jack that lowers or raises the lifting frame 5a by changing the rhombus shape created by several arm rods 14 by rotating the screw shaft 15 forward and backward by the operation handle 20. , One end side of four arm rods 14 which are formed to have appropriate lengths are axially connected to sleeves 19 which are screwed onto the screw shafts 15, respectively. The other end side of the lower two arm rods 14 is pivotally connected to the lower frame 1c of the machine frame 1, and the other end sides of the other two arm rods 14 located above the screw shaft 15 Are pivotally connected to the lower base frame 17 of the elevating frame 5a, so that they are respectively installed in rhombus shape on both sides of the machine frame 1. Then, the screw shaft 15 formed to have a length extending over both sides of the device frame 1 is threadedly arranged in a bridging manner over the sleeves 21 on both sides, whereby the lower frame 1c of the device frame 1 is installed.
A screw type lifting device (5b) is installed on the top of the lifting frame (5a) so that it can be lifted and lowered.

In addition, even if the operating handle 20 is attached to the operating end of the screw shaft 15 in an unremovable manner,
Although it may be formed in a detachable structure (shape) that can be removed as appropriate, by adopting the detachable structure as shown in the drawing, when the heat insulating cover 8 that encloses the entire apparatus machine frame 1 is put on and when it is put on, it becomes an obstacle. I won't. That is, by removing the handle 20 from the operation end of the screw shaft 15 after the raising / lowering operation of the root rising prevention lid 4, the heat insulating cover 8 that wraps the entire apparatus frame 1 does not interfere (see FIG. 7).

Thus, according to the germination / seedling raising apparatus of the present embodiment having the above-described configuration, floor soiling, seeding and covering with soil are spread on the box-carrying shelves 3 in each stage of the germination / seeding room 9. When carrying out the work of supporting and supporting a plurality of seedling raising boxes 2 ...
By operating the handle 20 of the screw-type lifting tool 5b of the lifting mechanism 5, the split lids 4a at each stage are pushed into the rear side of the germination / seedling chamber 9 and slid to make the root-prevention lid 4 overlapped and reduced. (The state of FIG. 8B). As a result, the root-up prevention lid 4 does not hinder the work of storing the seedling raising box 2 in the germination / seedling raising chamber 9, and the work can be performed smoothly and promptly. Then, after the storage of the seedling raising box 2 in the germination / seedling raising chamber 9 is completed, the split lids 4a at each stage are pulled out and slid to extend the root-prevention lid 4, and the handle 20 of the screw type lifting tool 5b is provided. By operation, the elevating frame 5a is lowered to close the opening of the seedling raising box 2 in each stage with the root-up prevention lid 4 in each stage to prepare for the germination stage. After the germination period of 2-3 days is over, the lifting frame 5a is raised by operating the handle 20 of the screw-type lifting tool 5b, and the root-prevention lid 4 is removed from the opening of the nursery box 2 at each stage to open the same opening. To prepare the seedlings for seedlings, and to prevent the roots from rising by the rooting prevention lid 4, seedlings 6 in the seedling raising box 2 that have germinated healthy with good root growth and rooting are planted in the germination and seedling raising room 9 Continue to grow to an appropriate seedling length (see Figure 7). When the seedling raising period is over and the sprouted seedlings 6 have grown to a seedling raising length suitable for rice planting, when the seedling raising box 2 is pulled out from the box mounting shelf 3 of each stage and taken out from the germination / seedling raising room 9, a split lid for each stage is used. 4a is pushed and slid into the rear side of the germination / seedling chamber 9 in the same manner as in the storing operation described above, and the root-preventing lids 4 at the respective stages are polymerized and reduced. As a result, the root-up prevention lid 4 does not hinder the work of taking out the seedling raising box 2 from the germination / seedling raising room 9, and the same work, that is, the germination / seedling raising chamber 9 of the seedling raising box 2
It is possible to smoothly and swiftly perform the work of putting in and taking out the product (the state of FIG. 8A).

The configuration of the root-prevention lid 4 that can be slidable and retractable in the front-rear direction is not limited to the above-mentioned configuration.
It is also possible to adopt a structure in which a large number of divided lids cut into strips are foldably connected to each other. That is, a bellows structure may be adopted. In short, the openings of the nursery boxes 2 arranged in several rows in the front-rear direction on the shelf shelves 3 at each stage can be slid in the front-rear direction with a size capable of closing the mutual opening in a stretched state. Any structure that can be expanded and contracted may be used.

9 to 13 show another embodiment of the elevating mechanism. The elevating mechanism 21 of the second embodiment is constructed by hoisting and lowering the hoisting frame 21a described in detail in the first embodiment. It is configured to move up and down, and the basic configuration of the elevating frame 21a and the mounting configuration of the lid receiving rail 12 for slidably supporting the root-prevention lids 4 of each stage to the elevating frame 21a are as follows. Since it is substantially the same as the detailed description of the first embodiment, the same reference numerals are used, and the detailed description thereof is omitted, and only the structural differences will be described below.

The elevating frame 21a is fixedly connected to both sides supporting the box receiving rails 12 of each stage and the lower end side of the central vertical frame 16 by a lower horizontal frame 22 extending in the front-rear direction and the left-right direction, and the upper end side in the front-rear direction. A vertical frame 16 is sandwiched between the front and rear sides of the box frame 3 located at the top and bottom of the machine frame 1 on both sides and in the center of the device frame 1 by means of an upper horizontal frame 23 extending in the direction. As shown in the drawing, it is supported by being sandwiched between a pair of rollers 24 which are rotatably mounted at intervals so that the apparatus frame 1 is provided so as to be able to move up and down.

[Effects of the Invention] Since the germination and seedling raising device of the present invention is constructed as described above, it has the following effects. Multiple seedling raising boxes are placed and supported on each stage of the box placing shelves arranged in multiple stages within the equipment machine frame at intervals that can grow the seedlings in the seedling raising box to the seedling raising length suitable for rice planting. After storing the seedling raising box in the equipment machine frame, the raising mechanism prevents the root-up prevention lid, which is arranged to be able to move up and down for each box mounting shelf, from being lowered by the elevating mechanism, and is placed on each step box mounting shelf. It is possible to prepare for the germination stage by preventing the root growth and germination of the seedlings in a healthy state with good rooting by covering the openings of each nursery box with rooting prevention lids at each stage. After the germination period has ended, by raising the root-up prevention lid, the root-up prevention lids are removed all together from the openings of the nursery boxes at each stage, and the sprouted seedlings are grown to a suitable seedling length for rice planting. You can prepare for the period. Moreover, when the seedling raising box is stored in the equipment frame or is taken out from the equipment frame, the root-prevention lids of each step can be reduced to the inside of the machine frame, so The root protection lid does not get in the way of taking in and out. Therefore, according to the germination and seedling raising apparatus of the present invention, after the germination period is finished, the conventional seedling raising box is put out to the outside or the taken-out seedling raising box is prepared for the seedling raising period in a greenhouse such as a greenhouse. It eliminates the need for the labor-intensive and time-consuming work of carrying it around, and can significantly reduce capital investment. As a result, the work for raising rice seedlings can be greatly improved, and labor can be saved and productivity can be improved. Moreover, the work for taking in and out the nursery box can be carried out smoothly and quickly, which is simple.
