[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a dispensing and discharging device with a switch door structure.

[0030] The utility model comprises a hopper, a discharge port 2 is arranged on one side of the hopper, a regulating screw 1 for conveying materials is arranged in the hopper, and the end of the regulating screw extends to the discharge port 2.

[0031] A movable door 3 is arranged outside the discharge port 2 , and the movable door 3 can move linearly relative to the discharge port 2 to close or open the movable door 3 .

[0032] During use, the material in the hopper is driven by the adjusting screw 1 to be continuously transported to the discharge port 2. When the discharge port 2 stops discharging a certain amount of material, the movable door 3 is started, and the movable door 3 moves until it is opposite to the discharge port 2, thereby completely blocking and closing the discharge port 2, thereby preventing the material from falling from the discharge port 2.

[0033] In this embodiment, a chamfered structure 3-1 is designed on the head edge of the movable door 3. When the movable door 3 moves to close the discharge port 2, the chamfered structure 3-1 on the movable door 3 tilts the material in the discharge port 2 so that the material in the discharge port 2 slides to the two sides of the movable door 3 to avoid the material in the discharge port 2 from getting stuck and hindering the movement of the movable door 3.

[0034] Furthermore, a chamfer is formed at the front of the movable door 3 to form an inclined blade. When the material is stuck between the movable door 3 and the discharge port 2, the chamfer is used to cut the material off, thereby further avoiding the material being stuck in the discharge port 2.

[0035] In this embodiment, the inclined surface formed by the chamfer is located on the side of the movable door 3 away from the discharge port 2, so that the front edge of the chamfer of the movable door can fit with the opening of the discharge port 2. During the movement of the movable door 3, the movable door 3 can more thoroughly push the material at the discharge port 2.

[0036] The chamfer dimension is 0.5-1 times of the thickness dimension of the movable door 3, so that the chamfered slope is wider.

[0037] In this embodiment, refer to Figure 4 As shown, the front part of the movable door 3 is designed as a semicircular structure 3-2. Compared with the rectangular movable door 3, the movable door 3 with the semicircular structure 3-2 extends from the middle of the discharge port 2 to the upper and lower sides of the discharge port 2 through the curved surface at its front end to close the discharge port 2, thereby reducing the resistance of the material in the discharge port 2 to the movable door 3 and the risk of material jamming.

[0038] In this embodiment, the semicircular radius of the semicircular structure 3-2 is 1-2 times the radius of the discharge port 2, so that when the semicircular structure 3-2 is opposite to the discharge port 2, the discharge port 2 can be completely blocked and closed by the movable door 3.

[0039] In this implementation, refer to Figure 5 As shown, the front part of the movable door 3 is designed as an angled structure 3-3, and the inclined surface of the angled structure 3-3 is tilted downward. In the process of the movable door 3 moving to block the discharge port 2, the movable door 3 with the angled structure 3-3 moves from the upper right side of the discharge port 2 to the lower left side of the discharge port 2 to gradually block the discharge port 2, so as to reduce the resistance of the material in the discharge port 2 to the movable door 3 and the risk of material jamming.

[0040] In actual use, the front portion of the movable door 3 can also be designed to be a cone or other shape, which also serves the purpose of reducing the resistance of the material to the movable door 3 and the risk of material jamming when the movable door 3 closes the discharge port 2.

[0041] In this embodiment, refer to Figure 1 and Figure 6 As shown, a driving mechanism 4 is installed on the hopper, and the telescopic end of the driving mechanism 4 is fixedly connected to the movable door 3. The driving mechanism 4 is a telescopic component driven by a hydraulic telescopic cylinder or a motor or compressed air, so that it can respond quickly and accurately drive the movement of the movable door 3.

[0042] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
