2b, an endless conveyor belt 23 is hung between the conveyors 2b.
a, 22b and a motor 24 fixed to the machine frame 21 are connected by a chain 25 so that the conveyor belt 23 can be driven. In particular, the transporter 2 is a portable type in which wheels 26 are attached to the lower ends of legs 21a constituting the machine frame 21, and can be easily installed at a predetermined place.

On the other hand, a hopper 4 is fixed to the carrier 2 via a gantry 3. The gantry 3 is formed by connecting structural steel such as an angle iron, and the lower end thereof is fixed on a machine frame 21 so as to straddle a conveyor belt 23.

The hopper 4 is a container formed in an inverted pyramid shape.
It is attached to the upper part of the gantry 3 in a state of being located above. In particular, the hopper 4 has a built-in stirring blade 42 so that the contents can be stirred, and an opening adjustment plate 43 facing the lower opening 41 is slidably attached to the lower outer wall to drop the hopper 4. The opening of the mouth r can be adjusted. Then, the flow rate of the contents in the hopper 4 which is about to fall from the lower surface opening 41 by the operation of the stirring blade 42 is reduced.
1 can be adjusted by a feeder 5 and an opening degree adjustment plate 43 provided in the vicinity of the first position.

The feeder 5 is composed of a roller 51 having a polygonal peripheral surface and a rotating shaft 52 fixed to the center of the roller 51, and is provided rotatably along the lower opening 41 of the hopper 4. ing. The roller 51 is, for example, an octagonal prism, and a rotating shaft 52 protruding from both ends in the longitudinal direction is supported by the gantry 3 via a bearing. In addition, a required gap is provided between the feeder 5 and the opening adjustment plate 43 along the longitudinal direction of the feeder, and the gap is a drop port r through which the contents of the hopper 4 pass.

Here, reference numeral 6 denotes a motor for driving the stirring blade 42 and the feeder 5, and the motor 6 is fixed to the gantry 3 via a bracket (not shown). The drive shaft 61 of the motor 6, the main shaft 42a of the stirring blade 42 and the feeder 5
The sprockets 62, 42b,
53 is fitted and connected by a chain 7. Therefore, by operating the motor 6, the stirring blade 42 and the feeder 5 can be synchronously rotated in the same direction.

FIG. 2 is a sectional view taken along line AA in FIG. As is apparent from this figure, the feeder 5 is provided along the lower surface opening 41 of the hopper 4 as described above, and in particular, the feeder 5 is partially overlapped with the lower surface opening 41 of the hopper 4. The equipment is arranged near one side of the side edge of the lower surface opening 41 so that the other side of the lower surface opening 41 of the hopper 4 communicates with the falling port r up and down. Note that 31
Is the above-mentioned bearing fixed to the gantry 3, and both ends of the rotating shaft 52 of the feeder 5 are fitted into this bearing 31.

The conveyor belt 23 is passed between the machine frames 21. When the tray 1 disposed above the conveyor belt 23 passes below the feeder 5, the contents of the hopper 4 passing through the dropper r are removed. Filling port 1 opened on top plate 14 of tray 1
4a flows into the pot in the tray 1.

Next, FIG. 3 shows a cross section orthogonal to the axis of the feeder 5. As shown in this figure, the feeder 5 has a roller 51 having a polygonal column shape, and a rotary shaft 52 penetrates the center of the roller 51 and is fitted. FIG. 4 shows an example in which the feeder 5 has a hollow shaft. At this time, the rotating shaft 52 is fixed to the center of the roller 51 via the rib 54. In addition, feeder 5
In another embodiment, besides the example illustrated in the drawings, a rotating shaft may be integrally protruded from both ends of the roller. In particular, the shape of the roller may be triangular, square, pentagonal, hexagonal, or the like. By the way, according to the feeder of the present application, since the ridge portion 51a is formed on the peripheral surface of the polygonal roller 51, the content of the hopper 4 can be prevented from spontaneously releasing due to slippage,
Thus, the flow rate can be adjusted by the rotation speed.

Next, the operation of the present apparatus will be described with reference to FIG. Here, for example, cultivation soil is stored in the hopper 4, and the trays 1 are arranged at required intervals in the transporter 2. When the motor 24 is operated in this state, the trays 1 are sequentially conveyed below the hopper 4. On the other hand, when the motor 6 is simultaneously operated at this time, the stirring blades 42 and the feeder 5 rotate, so that the cultivation soil in the hopper 4 flows out from the falling port r along the peripheral surface of the roller 51.

More specifically, when the flat surface of the peripheral surface of the roller 51 is parallel to the lower opening 41 of the hopper 4, the outflow of the cultivation soil is regulated, and the ridge 51 a of the roller 51 is fixed to the lower opening 41. When passing through the cultivation soil, the cultivation soil sent to the lower surface opening 41 side by the stirring blades 42 is scraped off by the ridge 51a.

Here, the flow rate of the cultivation soil is adjusted by controlling the rotation speed of the motor 6 to adjust the rotation speed of the feeder 5 and adjusting the opening degree of the falling port r by the opening adjustment plate 43. The cultivation soil that has flowed out is filled into the tray 1 by a fixed amount.

Although the present invention has been described as a quantitative feeder for cultivating soil, the quantitative feeder according to the present invention is suitable for storing flour such as flour in the hopper 4 and sending it to a predetermined container. Of course, it can be used.

[0026]

As is apparent from the above description, according to the present invention, since the main part of the feeder is formed as a polygonal roller, the structure can be simplified as compared with a belt conveyor or the like. Costs can also be significantly reduced.

The feeder of the present invention is safe because it has no protrusions such as fins, and does not cause clogging when the cultivation soil is stored and supplied to the hopper. It can be supplied smoothly even at times.

Further, the hopper is provided with an opening adjusting plate so that the opening of the drop opening formed between the hopper and the feeder can be adjusted. The flow rate can be easily adjusted by adjusting the rotation speed of the feeder.
