[0002]
[Prior art]
In the production of plant cultivation soil such as horticulture seedling cultivation and agricultural cultivation (vegetables, fruit vegetables, root vegetables, leaf vegetables, fruit trees, paddy rice, etc.), various types of inorganic and organic soil materials are used as raw materials. Various kinds of inorganic fertilizers and organic fertilizers as fertilizers, vermiculite, perlite, zeolite, charcoal, charcoal activated carbon, mulch and the like as soil amendments are used.
In addition, peat moss, crushed palm fruit, black peat, mulch, bark, bark compost, organic compost, and the like are used as the raw material of the organic material and the organic fertilizer.
[0003]
In an apparatus for producing horticultural soil (including cultivation seedling cultivation, agricultural cultivation, etc.) from the above various raw materials, a hopper for supplying these raw materials is often used.
For example, the hopper shown in FIG. 5 is shown in a method and an apparatus for producing cultivated soil for horticulture described in Japanese Patent Application Laid-Open No. 8-256593. In this hopper, when the raw material is supplied, the discharge port may be clogged, and as a result, the supply is stopped or the supply amount becomes unstable, and the manufactured product does not have the desired mixing ratio There was a fear.
[0004]
Especially in the supply of organic fertilizers such as peat moss, crushed palm fruit, black peat, mulch, bark, bark compost, organic compost, the fiber itself is apt to be entangled, and as it descends in the hopper However, the raw material is compressed and becomes harder, so that the flow tends to stop near the discharge port.

Further, in the above configuration, a moving wheel 18 is provided on the leg 1a of the hopper support frame 1 so that the hopper 2 can be moved.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment for carrying out the present invention will be specifically described below.
In the present invention, as shown in FIG. 3, a hopper 2 is fixed to a hopper support frame 1 for fixing a position on a conveyor belt conveyor 22 of a cultivation soil production line.
At the upper part of the hopper 2, a raw material opening / closing opening 24 for charging the raw material is provided.
[0011]
Then, as shown in FIG. 1, a pair of shaft holes 3, 3 corresponding to the horizontal direction are formed through the hopper 2 at the lower to middle positions of the lower oblique inclined side wall surfaces 2a, 2b.
Bearing portions 4 and 4 are provided outside the respective shaft holes 3 and 3, and a stirring shaft 6 having a large number of radial stirring claws 5 protruding at intervals on the bearing portions 4 and 4 on both sides thereof. Bearings 6a and 6b are provided.
[0012]
Then, one end 6 a of the stirring shaft 6 is connected to a rotation driving device 7 provided outside the hopper 2 via rotation transmission means 8.
FIG. 1 shows a mode in which the stirring shaft 6 is rotated by a motor via a chain 25 and a gear 26.
As shown in FIGS. 1 and 2, the rotation transmitting means by the chain 25 and the gear 26 may be provided with a separate rotary drive 7 for each drive mechanism and driven individually. It is also possible to provide an interlocking mechanism for several driving mechanisms from the machine 7 and drive them. By doing so, the number of rotary drives 7 can be saved (not shown).
[0013]
Further, a fixed-quantity cut-out belt conveyor 11 having a top-side conveyor belt 10 provided horizontally so as to cover the outlet 9 is provided below the outlet 9 at the bottom of the hopper 2. The cutout 12 is opened between the side discharge port 9a. The cut-out opening 12 is provided with a slide-type opening / closing adjustment plate 13 for turning the handle 21 to open and close the opening 12.
[0014]
Further, a control unit 15 for controlling the low-speed rotation of the stirring shaft 6 by the rotary driving device 7 and the speed of the transport belt 10 by the rotary driving device 14 is provided.
As shown in FIG. 4, the raw material cut out from the cutout opening 12 by the transport belt 10 by the opening and closing adjustment of the opening and closing adjustment plate 13, from the guide opening 23 provided at the end of the fixed cutout belt conveyor 11, It falls on the conveyor belt conveyor 22 of the line.
[0015]
In FIGS. 1 and 2 described above, the amount of the raw material sent by the transport belt 10 is adjusted by controlling the transport speed of the transport belt 10 so that the material can be cut out.

Can be controlled so that
[0019]
【The invention's effect】
The present invention is as described above. The hopper 2 for supplying the raw material for horticultural cultivation has a built-in rotary stirring blade 5, and the raw material itself is stirred by rotating the rotary stirring blade 5 at a low speed. By kneading, the raw material at the bottom in the hopper 2 is broken. This prevents the raw material from being clogged at the discharge port 2a, and allows the raw material to be smoothly discharged without stagnation.
In this case, there is also an advantage of helping to improve the porosity of the cultivated soil cultivation product obtained by breaking the feedstock itself before mixing.
[0020]
Further, under the hopper 2, features a quantitative cut belt conveyor 11, the speed of the conveyor belt 10 of the quantitative cut belt conveyor 11, by controlling, smooth discharge coupled with a rotary damper 16, the hopper 2 The raw materials in the container can be supplied accurately and smoothly to the conveyor belt conveyor 22 of the cultivation soil production line accurately by the set required mixing amount.
Further, if a rotary damper 16 is provided in the cutout 12, a more accurate amount of the raw material can be supplied.
As described above, according to the present invention, it is possible to supply a stable, smooth, and accurate amount on a conveyor belt conveyor of a cultivation soil production line. It can be manufactured efficiently.
