[0006] Preferably, the material discharge box is equipped with a stirring mechanism, which includes a second motor. The second motor is fixedly connected to the surface of the material discharge box, and a stirring rod is fixedly attached to the surface of the second motor. The second motor drives the stirring rod to rotate through an output shaft, and stirring blades are fixedly connected to the surface of the stirring rod.

[0007] Preferably, there are two sets of baffles and two sets of side frames. The rotating rod rotates on the surface of the discharge port through the side frames, and the adjusting plate and gear rotate synchronously with the rotating rod.

[0008] Preferably, there are two sets of adjusting plates, which are symmetrically distributed at the bottom of the discharge port. The adjusting plates rotate in opposite directions at the bottom of the discharge port, and the end of the adjusting plate away from the rotating rod is an inclined surface.

[0009] Preferably, the nut slides on the surface of the feed box by rotating via a bidirectional lead screw. There are two sets of nuts, and the two sets of nuts move in opposite directions.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A material feeding device for gypsum mortar production includes a feeding box 1, a feed hopper 11 fixedly connected to the top of the feeding box 1, and a discharge port 12 fixedly connected to the bottom of the feeding box 1. A quantity control mechanism is provided on the surface of the discharge port 12, including a baffle 2 fixedly connected to the surface of the discharge port 12. A side frame 21 is fixedly connected to the surface of the discharge port 12, a rotating rod 22 is rotatably connected to the surface of the side frame 21, an adjusting plate 23 is fixedly connected to the surface of the rotating rod 22, and a gear 24 is fixedly connected to the surface of the rotating rod 22. A first motor 25 is fixedly connected to the surface of the discharge port 12. A bidirectional lead screw 26 is fixedly connected to the output shaft of the first motor 25. A nut 27 is threadedly connected to the surface of the bidirectional lead screw 26. A connecting rod 28 is fixedly connected to the bottom of the nut 27. A gear 29 is fixedly connected to the bottom of the connecting rod 28. The gear 29 and the gear 24 mesh with each other. The quantity control mechanism controls the quantity by adjusting the angle of the baffle 2 and the adjusting plate 23 at the bottom of the discharge port 12. By controlling the angle of the two sets of adjusting plates 23 at the bottom of the discharge port 12, the discharge amount is controlled.

[0025] Furthermore, the material discharge box 1 is equipped with a stirring mechanism, which includes a second motor 3. The second motor 3 is fixedly connected to the surface of the material discharge box 1. A stirring rod 31 is fixedly fixed to the surface of the second motor 3. The second motor 3 drives the stirring rod 31 to rotate through the output shaft. A stirring blade 32 is fixedly connected to the surface of the stirring rod 31. The stirring mechanism can stir the raw materials inside the material discharge box 1 to avoid material blockage and reduce the phenomenon of uneven material discharge.

[0026] Furthermore, two sets of baffles 2 and two sets of side frames 21 are provided. The rotating rod 22 rotates on the surface of the discharge port 12 through the side frame 21. The adjusting plate 23 and the gear 24 rotate synchronously with the rotating rod 22. By driving the gear 24 to rotate, the rotating rod 22 can drive the adjusting plate 23 to rotate at the bottom of the discharge port 12. The adjusting plate 23 changes its tilt angle at the bottom of the discharge port 12 by rotating.

[0027] Furthermore, two sets of adjusting plates 23 are provided and symmetrically distributed at the bottom of the discharge port 12. The adjusting plates 23 rotate in opposite directions at the bottom of the discharge port 12. The two sets of adjusting plates 23 are distributed in a figure-eight shape at the bottom of the discharge port 12. The adjusting plates 23, together with the baffle 2, form a new opening at the bottom of the discharge port 12, thereby controlling the discharge amount of raw materials. The end of the adjusting plate 23 away from the rotating rod 22 is inclined. The inclined surfaces of the two sets of adjusting plates 23 can be connected together, thereby blocking the discharge port 12 with the baffle 2.

[0028] Furthermore, the nut 27 slides on the surface of the feed box 1 by rotating via the bidirectional lead screw 26. There are two sets of nuts 27, and the two sets of nuts 27 move in opposite directions. The nut 27 drives the rack 29 to move via the connecting rod 28. The rack 29 drives the gear 24 to rotate on the side frame 21. The gear 24 drives the adjusting plate 23 to rotate via the rotating rod 22. Since the two sets of racks 29 move in opposite directions, the two sets of gears 24 rotate in opposite directions, which in turn makes the adjusting plate 23 rotate in opposite directions at the bottom of the discharge port 12. The two sets of adjusting plates 23 control the discharge amount of raw materials by rotating.

[0029] Furthermore, multiple sets of stirring blades 32 are provided, and the multiple sets of stirring blades 32 are arranged in a circular and uniform manner on the stirring rod 31. The stirring blades 32 are plate-shaped and can drive the raw materials inside the material box 1 to tumble.

[0030] Furthermore, the stirring blade 32 rotates inside the discharge box 1 via the stirring rod 31. The stirring rod 31 and the stirring blade 32 are located directly above the discharge port 12. When there is a lot of raw material inside the discharge box 1, blockage will occur inside, resulting in uneven discharge.

[0031] Working principle: The output shaft of the first motor 25 drives the bidirectional lead screw 26 to rotate. The bidirectional lead screw 26 drives two sets of nuts 27 to move on the surface of the feed box 1. During the movement of the nuts 27, the connecting rod 28 drives the rear rack 29 to move. The rack 29 drives the gear 24. Since the rack 29 moves in opposite directions, the two sets of gears 24 rotate in opposite directions. The gear 24 drives the adjusting plate 23 to rotate at the bottom of the discharge port 12 through the rotating rod 22. The adjusting plate 23, together with the baffle 2, forms a new opening at the bottom of the discharge port 12. The adjusting plate 23 controls the size of the opening by rotating, thereby controlling the amount of raw material discharged.

[0032] The output shaft of the second motor 3 drives the stirring rod 31 to rotate, and the stirring rod 31 drives multiple sets of stirring blades 32 to rotate inside the material box 1. During the rotation, the stirring blades 32 continuously tumble the raw materials inside the material box 1 to prevent the raw materials inside the material box 1 from clogging and to make the raw materials discharge evenly.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
