The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Reference Figures 1-3 According to an embodiment of the flour sieving device of the present invention, it includes a machine base 11, which is supported by a support rod. The machine base 11 is provided with a sieving chamber 12, and a plurality of sieving plates 13 are arranged at equal intervals in the sieving chamber 12, and a filter screen is provided in the sieving plate 13.

[0029] Furthermore, in order to facilitate cleaning of the filter screen inside the screening plate 13, the screening plate 13 is configured to slide left and right in the screening chamber 12, and the opening of the screening chamber 12 faces to the right. A cabinet door 14 for closing the screening chamber 12 is hinged on the right side of the machine base 11. A spring is installed on the side of the cabinet door 14 to abut against the screening plate 13. It also includes a vibration mechanism for controlling the left and right movement of the screening plate 13.

[0030] The upper and lower sides of the sieving chamber 12 are respectively provided with a feed inlet and a discharge outlet.

[0031] When it is necessary to screen the material, the operator uses the vibration mechanism to make each screening plate 13 vibrate left and right. Then, the operator puts the material into the screening chamber 12 through the feed port. At this time, the material can pass through the filter screen in each screening plate 13 and finally pass through the discharge port to complete the screening of the material.

[0032] In addition, to make the flour sieving device easier to clean, a funnel 15 is provided at both the inlet and the outlet.

[0033] To facilitate the disassembly and assembly of the funnel 15 and to make the flour sieving device easier to clean, the funnel 15 includes a funnel section and a straight tube section connected to the lower end of the funnel section. A sliding groove is provided on the side of the inlet and the outlet, and an abutment plate 16 is slidably connected in the sliding groove. The abutment plate 16 presses against the straight tube section. A control rod threaded to the abutment plate 16 is also rotatably connected inside the machine base 11. A knob 17 is installed at the end of the control rod that extends outside the machine base 11. The operator can remove the funnel 15 by moving the abutment plate 16 to the left using the knob 17.

[0034] The vibration mechanism includes a push plate 21 slidably connected to the left side of the sieve chamber 12. The push plate 21 has multiple push plates that are equally spaced vertically and abut against the left end of each of the sieve plates 13.

[0035] A bracket is provided on the machine base 11, and a motor 18 is mounted on the bracket. The output shaft of the motor 18 extends downward and is located on the left side of the machine base 11. Multiple eccentric wheels 19 are fixed on the output shaft. A hinge plate 20 is rotatably connected to the outside of the eccentric wheels 19. The hinge plate 20 is hinged to the left end of each push plate 21 extending to the left side of the machine base 11. With this configuration, when the motor 18 is energized to drive the eccentric wheels 19 to rotate, the hinge plate 20 will drive the push plate 21 to move periodically left and right. When the cabinet door 14 is fixed to the side of the machine base 11 by a pin or latch, the spring on the cabinet door 14 will press to the left onto the screening plate 13. With the cooperation of the left and right moving push plate 21, the screening plate 13 can move periodically left and right.

[0036] The right end of the screening plate 13 is equipped with a handle so that the staff can take out the screening plate 13 when the cabinet door 14 is opened. In order to keep the above movement stable, the spring is provided in two rows distributed in front and behind, respectively located on the front and back sides of the handle.

[0037] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
