Referring to fig. 2, the feeding meter is including setting up the first baffle 8 in mechanism sand inlet pipe 4, first opening 9 has been seted up on the first baffle 8, first opening 9 department is provided with rotor plate 10, the one end of rotor plate 10 is passed through the torsional spring and is connected with the rotation of first baffle 8, and the other end of rotor plate 10 is provided with magnet 11, is provided with magnetic field sensor 12 on the first baffle 8, magnetic field sensor 12 links to each other with controller 7 signal. When the machine-made sand falls into the stirring chamber 5 from the machine-made sand feeding pipe 4, the falling machine-made sand overcomes the torsional force of the torsional spring to push the rotating plate 10 away, when the rotating plate 10 is pushed away, the magnet 11 is far away from the magnetic field sensor 12, so that the magnetic field generated by the magnet 11 cannot be detected by the magnetic field sensor 12, a signal that the magnetic field is not detected is sent to the controller 7, the controller 7 can calculate the time for the machine-made sand to continuously fall into the stirring chamber 5 according to the duration time for the magnetic field not detected by the magnetic field sensor 12, the machine-made sand amount falling into the stirring chamber 5 in unit time can be calculated by combining the area of the first opening 9, and the machine-made sand amount falling into the stirring chamber 5 is further calculated by combining the duration time for the machine-made sand to continuously fall into the stirring chamber 5. When the machine-made sand is not thrown into the machine-made sand feeding pipe 4 any more, the rotating plate 10 moves towards the first partition plate 8 under the torsion force of the shape recovered by the torsion spring and blocks the first opening 9, and at this time, the magnetic field sensor 12 can detect the magnetic field of the magnet 11 again and send a corresponding electric signal to the controller 7.

In this embodiment, when the controller 7 receives a signal that the magnetic field sensor 12 transmits no detected magnetic field, which indicates that organic sand continuously enters the stirring chamber 5 from the mechanical sand feeding pipe 4, the controller 7 controls the electric cylinder 16 to drive the sliding plate 17 to move toward the sliding chute 15, so that the second opening 14 is opened, and the natural sand in the natural sand feeding pipe 2 and the stone in the stone feeding pipe 3 can fall into the stirring chamber 5 through the second opening 14 of the electric control valve to be mixed with the mechanical sand. When the controller 7 receives a signal transmitted from the magnetic field sensor 12 to detect the magnetic field, the electric cylinder 16 is controlled to drive the sliding plate 17 to move toward the other side of the chute 15, so that the sliding plate 17 blocks the second opening 14 to stop the supply of the natural sand and stone to the agitating chamber 5.

On this basis, the area ratio of the first opening 9 in the machine-made sand feed pipe 4 to the second opening 14 in the natural sand feed pipe 2 to the second opening 14 in the stone powder feed pipe 3 is 45.

Specifically, rabbling mechanism includes driving motor 18, dwang 19 and stirring portion 20, driving motor 18 sets up in the motor room 27 at box 1 top, and driving motor 18's output shaft is connected with the top of dwang 19 in stretching into teeter chamber 5 for driving motor 18 can drive dwang 19 and rotate, and stirring portion 20 is connected with dwang 19, makes dwang 19 can drive stirring portion 20 and rotate. The drive motor 18 is connected to the controller 7 via a control circuit.
