[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seedling cultivation soil supply device for seedling raising boxes.

[0002]

[Prior art]

 It can be said that this kind of seedling raising soil supplying device is almost the same as a known seedling raising seeding machine because of its configuration. That is, FIGS. 7 and 8 show a typical example thereof, and (u) is a general term for a drive unit, and is a device frame (1) for installation on a work floor and an axis for the device frame (1). The nursery box carrier (2), which is composed of endless belts and rollers, is placed in parallel with the upper stage position of the nursery box (3). The soil feeding belt (4) is provided.

A cultivating soil accommodating hopper (h) is fixedly installed on the apparatus frame (1) from above so that the cultivating soil feeding belt (4) serves as a movable bottom surface. The seedling-raising soil (m) in the hopper (h) is fed out and dropped into the seedling-raising box (3) which is being driven by the drive 2) by the feeding drive of the feeding belt (4). (5) is a soil feeding port formed on the front wall surface of the hopper (h), and (6) is a metering shutter for opening and closing it.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned hopper (h) is shaped like an overall square funnel, and its wall surface is shaped into a slanting inclined surface, and along with this, the feeding belt so that the nursery soil (m) will fall naturally. It is only adapted to be fed from the hopper (h) only by (4).

Therefore, if the seedling-raising soil (m) to be fed is soil (nonmetallic mineral) or a heavy material composed of a mixture of the soil and an organic matter, or a granular material having a constant size and shape, For example, a lightweight product consisting only of plant fibers and other organic substances, as proposed by the present inventor in Japanese Patent Application No. 4-176250, or an at random crushed product of lightweight and size / shape, The seedling-raising soil (m) having such a shape causes a bridging phenomenon in the above-mentioned hopper (h), which results in hollowing of the lower end portion rather than the chain lines (a) and (b) in FIG. It is not possible to smoothly and surely feed from (h) to the nursery box (3) in a fixed amount.

[0006] As a countermeasure against this, when the hopper (h) is vibrated, the seedling-raising soil (m) is positively dropped. It becomes difficult to entangle, and it solidifies into a solid state that is tightened more and more, and it becomes impossible to feed it from the cultivation soil feeding port (5) of the hopper (h), resulting in variations in the amount supplied to the nursery box (3). is there.

[0007] In particular, the seedling-raising soil (m) having the above-mentioned properties, as a residence and a diet, is proliferated by soil microorganisms, so that the mycelia of the seedling-raising soil are as if they spread a spider web before being put into the hopper (h). Due to the high density of entangled states, the above-mentioned problems will occur remarkably.

[0008]

[Means for Solving the Problems]

 The present invention intends to improve such a problem, and a nursery box carrier which is composed of a device frame for installation on a work floor and an endless belt or roller axially mounted on the device frame because of its structure. As a related state in which it is juxtaposed to the upper position of the seedling raising box, an endless soil feeding belt that is axially mounted on the equipment frame and a bottom state that is covered by the soil feeding belt are attached to the equipment frame. With the attached soil storage hopper, the seedling raising soil stored in the hopper is driven by the traveling movement of the soil feeding belt, from the soil feeding outlet opening to the front wall surface of the hopper, and is moved forward by driving the carrier. In the seedling-raising soil supply device that is designed to be sequentially fed out and dropped into the inside nursery box, either the front wall surface of the above hopper or one of the front wall surface and the left or right Alternatively, both side wall surfaces are shaped as vertical surfaces, the fertilizer feeding mouth is cut out at the lower end of the front wall surface, and in combination with the fertilizer feeding belt, a rotary impeller with a protrusion that feeds out the seedling raising soil quantitatively. The main feature of the above is that it is mounted inside the hopper based on the corresponding positional relationship facing the above-mentioned soil feeding port.

[0009]

[Action]

 According to the above configuration of the present invention, the seedling raising box is moved forward by driving the carrier, and the seedling raising soil contained in the other hopper is moved along with the traveling of the soil feeding belt. The soil will be transferred to the soil feeding port that opens on the front wall, but the front wall is erected as a vertical plane, and at the position near the feeding port that opens at the lower end of the soil, a fixed amount during rotation is determined. Since the feeding impeller is present, the seedling-raising soil surely drops in the hopper, and the entanglement is released by the impeller's protrusions.

As a result, not only when the seedling-raising soil is the heavy weight mentioned at the beginning or the granular material having a constant size and shape, but also the light weight material consisting only of the residue of plant fiber and other organic substances. In addition, even if it is a lightweight and randomly crushed product of a size and shape, it does not cause any bridging phenomenon in the hopper and clogging phenomenon of the soil feeding hole and is adjusted in advance. It is possible to reliably and smoothly deliver a fixed amount from the hopper into the nursery box on the carrier.

[0011]

【Example】

 The detailed construction of the present invention will be described below with reference to the illustrated embodiment. FIG. 1 shows the general outline of the present invention, and (U) is a general term for a drive unit. As in the case of the product, the equipment frame (11) for installation on the work floor, the nursery box carrier (12) consisting of endless belts and rollers mounted on the equipment frame (11), and the nursery. As a state of being in parallel with the upper position of the box (13), it also has an endless cultivating soil feeding belt (14) axially mounted on the device frame (11).

Then, when the nursery box carrier (12) is driven by a drive source (not shown) such as a motor so as to sequentially advance the nursery box (13) in the arrow direction (F), The soil feeding belt (14) is also driven to rotate in the same direction.

(H) is a so-called cassette type detachable / removably attached and fixed to the device frame (11) of the drive unit (U) from above, and the cultivating soil accommodating hopper is under the attached state. However, the bottom surface of the hopper (H) is properly covered as a movable floor surface by the above-mentioned soil feeding belt (14) as shown in FIGS.

In the illustrated embodiment, a screw fastener (15) consisting of a bolt and a nut is adopted as a fixing means for attaching the hopper (H), but it can be attached to and detached from the device frame (11). As long as it is, it is of course possible to adopt a locking hook or other means instead of this.

In the case of the present invention, the hopper (H) basically has a square funnel shape as apparent from FIGS. 1 and 2, but unlike the conventional products of FIGS. The wall surface (16) and either the left or right side wall surface (17) are erected as vertical planes. Further, at the lower end portion of the front wall surface (16) forming the vertical plane, a culture soil feeding port (18) is cut out with a diameter as large as possible.

However, as suggested by the modified embodiment of FIG. 5 corresponding to FIG. 2, not only the rear wall surface (19) of the above-mentioned hopper (H) but also its left and right side wall surfaces (17) are inclined upward. It is permissible to increase the storage capacity of the nursery soil (M) as a sloped surface and form only the remaining front wall surface (16) as a vertical surface.

The reason why the soil feeding port (18) of the above-mentioned hopper (H) is opened as large as possible is that the inside of the hopper (H) is set so that it can be easily inspected through the inside of the hopper (H). Even if a bridging phenomenon occurs in the nursery soil (M), the operation tool can be easily inserted from here so that the nursery soil (M) can be easily dropped.

(20) is a metering shutter that opens and closes the soil feeding port (18), and by raising and lowering this, the seedling cultivating soil (M) is moved from the hopper (H) to the nursery box (13). The amount of supply can be adjusted. Although (21) shows the butterfly bolt for operating the set, the ascending / descending operation means may use a meshing rotation mechanism composed of a rack and a pinion or other means.

Further, (R) is a rotary impeller for fixed amount feeding, which is axially mounted inside the hopper (H), as a positional relationship facing the soil feeding port (18) of the front wall surface (16). And a rotary shaft (22) that horizontally traverses the hopper (H), and a plurality of soil dissociation protrusions (23) that integrally project radially from the circumferential surface of the rotary shaft (22). Consists of.

Reference numeral (24) is a transmission pulley fixed to one end of the rotary shaft (22), and (25) is a drive motor for the rotary impeller (R), which is a rear wall surface of the hopper (H) ( The output pulley (26) and the transmission pulley (24) are connected to each other via a transmission belt (27). (28) is a bearing of the rotating shaft (22).

Then, the rotary impeller (R) is rotated in the direction of the arrow (P) in FIGS. 1 and 4 by the drive motor (25) thereof, and the protrusion (23) thereof causes the seedlings in the hopper (H) to grow. The soil (M) is surely released, and together with the running action of the soil delivery belt (14), the seedling box (18) is opened from the delivery port (18) opening on the front wall surface (16) of the hopper (H). It is possible to smoothly feed out a fixed amount into the inside of 13) without causing a clogging phenomenon of the feeding port (18).

The spine (23) of the rotary impeller (R) serves to release the high-density entanglement of the nursery soil (M), and thus makes the vertical plane of the hopper (H). Together with the front wall surface (16), the seedling-raising soil (M) is surely dropped without fear of causing a bridging phenomenon in the hopper (H).

In that case, in terms of the lightweight seedling cultivating soil consisting of only organic substances mentioned above and the lightweight and cultivating seedling cultivating soil of which size and shape are not constant, the protrusion of the rotary impeller (R) is mentioned. For the child (23), it is effective to use this as a metal wire rod and set the pitch between the adjacent gaps roughly.

A lid is used, and as its literal protrusions (23) are not distributed in a scattered manner, and a strip having a constant length extending along the axial direction of the rotating shaft (22) is used, or adjacent to the strip. This is because if the pitches that fit together are small, the seedling cultivation soil (M) with the above properties may become entangled or clogged. From that meaning, in the illustrated embodiment, the protrusion (23) of the metal wire rod is passed through the rotary shaft (22) or welded to the circumferential surface of the rotary shaft (22) so that the rotary shaft (22) is The dots are scattered in a cross-shaped orthogonal state when viewed from the axial direction and in a so-called staggered arrangement when viewed from the radial direction.

Furthermore, the protrusions (23) of the rotary impeller (R) are in a state as close as possible to the extent that they do not interfere with the soil feeding belt (14), and the seedling growing soil (M) is delivered without leakage. ), But as long as this effect can be achieved, a plurality of protrusions (29) are provided on the surface of the soil feeding belt (14) as suggested in the modified embodiment of FIG. A so-called belt with a lug that overhangs in a distributed state may be adopted.

In using the present invention having the above-mentioned structure, the seedling raising box carrier (12), the soil feeding belt (14) and the rotary impeller (R) are driven to beat while the hopper (H) While feeding the seedling cultivation soil (M) from above, the opening degree of the soil cultivation feeding port (18) is adjusted to a predetermined level by the metering shutter (20).

Then, the nursery box (13) advances by the carrier (12) in the direction of the arrow (F) in FIG. 1, and within the hopper (H) the nursery cultivation medium (M) contained therein. However, as the soil feeding belt (14) travels, it is transferred to the soil feeding outlet (18) opening on the front wall surface (16) of the hopper (H). Since (16) is erected as a vertical plane, and moreover, there is a rotating fixed amount feeding impeller (R) in the vicinity of the feeding port (18) that opens at the lower end thereof, the above The seedling-raising soil (M) will surely fall in the hopper (H), and the entanglement will be released by the protrusions (23) of the rotary impeller (R).

As a result, not only when the seedling-raising soil (M) is the heavy weight mentioned above or a granular material having a constant size and shape, it is composed only of plant fiber residues and other organic substances. Even if it is a lightweight material, or a lightweight and randomly crushed material of a size and shape, it does not cause any bridging phenomenon in the hopper (H) or clogging phenomenon of the soil feeding port (18). , It is possible to reliably and smoothly supply a fixed amount, which is adjusted in advance by the metering shutter (20), from the hopper (H) into the seedling raising box (13) on the carrier (12). .

In addition, even if the front wall surface (16) of the hopper (H) is erected as a vertical surface and the cultivation soil feeding port (18) is formed at the lower end portion of the hopper, the cultivation seedling cultivation soil having the above-mentioned properties is obtained. Although it is possible to feed (M) out of the hopper (H), it is difficult to make the amount of feed fed out uniform.

In this respect, in the present invention, in addition to the above-mentioned special configuration of the hopper (H), the fixed-width feeding rotary impeller (R) facing the culture soil feeding port (18) is also axially supported inside the hopper (H). Since the impeller (R) has a protrusion (23) overhanging, the seedling raising soil (M) having the above-mentioned properties is effectively released by itself, and the seedling raising box (13). It is possible to equalize the amount of supply to the plant without any variation, and the synergistic effect has a special technical meaning.

In addition to such a function, not only the front wall surface (16) of the hopper (H) but also the left or right side wall surface (17) or both side wall surfaces (17) of the hopper (H) are shaped as vertical surfaces, and further the soil feeding belt ( By using 14) as a belt with lugs, the protrusions (29) of which are integrally projected from the surface, it becomes possible to operate more effectively.
