な移送ができなくなる。 The hopper with dispensing device configured in this way is
Since the second screw 11 stirs the raw material outside the first trough 7, the bridging phenomenon of the raw material near the bottom outlet 2 of the hopper 1 can be avoided, and the first screw 11 stirs the raw material outside the first trough 7. This method is suitable for supplying raw materials from 7 to the processing device 13 through the second trough 9 without leaving a trace. However, depending on the type of raw materials handled and the number of first and second screws,
Depending on the lateral feed speed of 0 or 11, the following problem occurs which hinders the above effects. In other words, the raw material that has been fed horizontally by the second screw 11 is
The material is pressed against the side walls and 8 of the trough 7 and degassed, and the raw material in that area tends to become compacted and harden. When the raw material hardens in this way,
Smooth transfer by the first screw 10 from the first trough 7 to the processing device 13 via the second trough 9 becomes impossible.

ツパを提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a hopper with a dispensing device that can prevent the raw material from solidifying near the side wall of the first trough and dispense any raw material without leaving a trace.

る。 In the hopper with a dispensing device of the present invention, a first trough for a cross-feed conveyor whose bottom is closed is attached to the dispensing port at the bottom of the hopper, and the side wall of the first trough has a transfer cross-sectional area larger than that of the first trough. A second trough for a small cross-feeding conveyor is provided in series, a first screw is provided from the inside of the first trough to the inside of the second trough, and the raw material is transferred into the second trough.
A second screw is provided which feeds horizontally toward the trough side, and an air duct is provided which communicates the upper position of the first trough side wall where the second trough is connected with the lower side of the second trough. It is characterized by:

されている。 2 and 3 show a first embodiment, which differs from FIG. 1 in that an air duct 16 is provided. This air duct 16 communicates between the upper side of the side wall 8 of the first trough 7 and the lower side of the second trough 9. Here, it is fixed to the inner wall 17 of the hopper 1 and its lower end is connected to the first trough 7. A molding 18 opens above the side wall 8 of the hopper 1 and extends upwardly along the inner wall 17 of the hopper 1 with its upper end closed. It is composed of a pipe 20 communicating with a passage 19 formed by the molding 18 and the inner wall 17.

で原料の固まりを軽減できる。 Because of this configuration, even if the raw material is pressed against the side wall 8 by the second screw 10 and attempts to be degassed, the raw material in this part is in contact with air via the passage 19 and the pipe 20, so that Unlike the conventional method, sufficient deaeration is not performed, and the clumping of the raw material near the side wall 8 can be reduced.

原料を表わす。 4 and 5 show a second embodiment, in which an air duct 16 communicates the upper side of the side wall 8 of the first trough 7 with the lower side of the second trough 9 and the upper part of the tank of the hopper 1. This embodiment differs from the first embodiment in that it does so. Here, the upper end 18a of the molding 18 extends to the tank upper part 21 of the hopper 1 and is open. 22 represents the raw material.
このように構成された場合には、第１の実施例

差が増加しないものである。 That is, since the air pressure in the tank upper part 21 of the hopper 1 and the air pressure in the casing 14 on the lower side of the second trough 9 can be equalized, the sudden pressure in the tank upper part 21 at the start of charging from the raw material charging device 3 to the hopper 1 The rise can be eased. Further, when discharging by the lateral conveyor 6, the air pressure in the casing 14 increases and the air pressure in the tank upper part 21 of the hopper 1 decreases, but since the two are communicated through the air duct 16, the air pressure in the casing 14 cannot be reduced. is possible,
Dust generation can be prevented. Furthermore, as shown by the imaginary lines in FIG. Since the tank upper part 21 and the casing 14 are in communication with each other, the measurement error does not increase due to dust collection on the processing device 13 side.

のである。 As explained above, according to the hopper with a dispensing device of the present invention, since the air duct is provided that communicates the upper position of the side wall of the first trough with the lower side of the second trough, the raw material near the side wall is This prevents the raw material from degassing due to the transfer of the second screw, so the raw material does not solidify near this side wall, and the raw material can be smoothly discharged by the first screw. This is something to look forward to.
