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, 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
evacuated pressed against the side wall 8 of the trough 7 of
The raw material in that area tends to become compacted and harden. If the raw material hardens in this way,
Smooth transfer by the first screw 10 from the trough 7 to the processing device 13 via the second trough 9 becomes impossible.

る。 In the hopper with a dispensing device of the present invention, a first trough for a cross-feeding 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 for horizontal feeding toward the trough side of the hopper, and an air duct is provided that communicates the upper part of the first trough side wall where the second trough is connected with the upper part of the tank of the hopper. It is characterized by

す。 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 the upper position of the side wall 8 of the first trough 7 with the tank upper part 17 of the hopper 1. Here, it is fixed to the inner wall 18 of the hopper 1, and its lower end is connected to the side wall of the first trough 7. A molding 1 opens at a position above 8 and extends upward along the inner wall 18 of the hopper 1, with its upper end opening at the tank upper part 17.
It is composed of 9. 23 represents the raw material.

りを軽減できる。 With this structure, even if the raw material is pressed against the side wall 8 by the second screw 11 and is about to be degassed, this part will be removed through the passage 20 formed by the inner wall 18 of the hopper 1 and the molding 19. Since the raw material is in contact with air, it is not sufficiently degassed as in the conventional case, and the clumping of the raw material near the side wall 8 can be reduced.

られている。 4 and 5 show a second embodiment, in which the air duct 16 connects the upper position of the side wall 8 of the first trough 7 and the lower side of the second trough 9 as well as the tank upper part 17 of the hopper 1. This embodiment differs from the first embodiment in that they communicate with each other. Here, a pipe 21 is provided, one end of which opens inside the casing 14 and the other end of which communicates with the passage 20.
このように構成された場合には、第１の実施例

誤差が増加しないものである。 That is, since the air pressure in the tank upper part 17 of the hopper 1 and the air pressure in the casing 14 on the downstream side of the second trough 9 can be equalized, a sudden pressure increase in the tank upper part 17 at the start of charging from the raw material charging device 3 to the hopper 1 can be prevented. can be alleviated. Furthermore, when discharging by the lateral conveyor 6, the air pressure in the casing 14 increases and the air pressure in the tank upper part 17 of the hopper 1 decreases, but since the two are communicated through the air duct 16, the air pressure in the casing 14 can be reduced. can prevent dust generation. Furthermore, as shown by the imaginary lines in FIG. Since the tank upper part 17 and the casing 14 are in communication, the measurement error does not increase even if dust is collected on the processing device 13 side.

原料のスムーズな排出を期待できるものである。 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 upper part of the tank of the hopper, the raw material near the side wall can be brought into contact with air. This prevents degassing of the raw material due to the transfer of the second screw, so the raw material does not solidify near this side wall, and smooth discharge of the raw material by the first screw can be expected. be.
