DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1 、 Figure 2 、 Figure 3As shown, a reduction weighing device includes a silo 1 with a discharge port 101, a weight sensor 5 and a support frame 2, the upper and lower sides of the weight sensor 5 are respectively connected to the silo 1 and the support frame 2, a hollow closing plate 6 is rotatably connected in the discharge port 101 through a sealed bearing, a first drive motor 3 connected to the closing plate 6 is fixed to the outer side of the silo 1 by bolts, the upper and lower sides of the closing plate 6 are rotatably connected to the connecting shaft 8 through bearings, the annular side of the connecting shaft 8 is welded with a rotating plate 7 located inside the closing plate 6, the upper and lower sides of the rotating plate 7 are sealed with the closing plate 6, and a second drive motor 9 connected to the connecting shaft 8 is installed on the lower side of the closing plate 6 by bolts, and the upper and lower sides of the closing plate 6 and the rotating plate 7 are provided with two left-right symmetrical fan-shaped openings.

[0019] During discharging, the staff controls the first drive motor 3 to drive the closing plate 6 to rotate to a vertical state. At this time, the silo 1 discharges at the maximum flow rate and monitors the weight in the silo 1 through the weight sensor 5 to judge the discharge amount of the material in the silo 1. When the discharge amount of the material is close to the specified amount, the staff controls the first drive motor 3 to drive the closing plate 6 to rotate until the side of the closing plate 6 is sealed with the inner side of the discharge port 101. Then the staff controls the second drive motor 9 to drive the rotating plate 7 to rotate. By rotating the rotating plate 7, the overlap between the rotating plate 7 and the fan-shaped opening on the closing plate 6 is controlled to control the discharge rate of the material. The amount of discharged material is monitored by the weight sensor 5, thereby achieving the effect of accurately controlling the discharge amount of the material and reducing material waste. When the discharge of the material reaches the specified amount, the staff controls the rotating plate 7 to rotate until it completes the overlap with the fan-shaped opening of the closing plate 6. At this time, the discharge port 101 is closed and the material cannot be discharged.

[0020] In this embodiment, the support frame 2 includes four support legs 201 arranged in a rectangular array, and two upper and lower connecting columns 202 are welded to the opposite sides of the support legs 201, and two cross-arranged support ribs 203 are welded to the opposite sides of the upper and lower connecting columns 202. When in use, the support frame 2 can support the silo 1, thereby ensuring the stability of the silo 1 during use. At the same time, the support ribs 203 increase the supporting strength of the support frame 2, further improving the reliability of the silo 1 during use.

[0021] In this embodiment, a bottom plate 4 is welded to the lower side of the support leg 201. When in use, the bottom plate 4 increases the contact surface between the support leg 201 and the ground, further improving the stability of the support leg 201 when in use.

[0022] In this embodiment, the fan-shaped openings of the closing plate 6 and the rotating plate 7 are of the same size, and the included angle of the fan-shaped openings is less than 45°.

[0023] In this embodiment, a motor protection shell 10 is fixed to the lower side of the closing plate 6 by bolts, and the second drive motor 9 is located inside the motor protection shell 10. When in use, the motor protection shell 10 can prevent the second drive motor 9 from direct contact with the material and prevent the material from entering the second drive motor 9, thereby improving the service life of the second drive motor 9.

[0024] In this embodiment, a material guide platform 11 is welded on the side surface of the closing plate 6. The material guide platform 11 is a conical platform. When in use, the material guide platform 11 can effectively make the material slide to the circumference of the material guide platform 11, and can guide the material to fall into the fan-shaped opening to a certain extent.
