Based on the embodiments of 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.

[0030] like Figure 1-5 As shown, the utility model has the following specific embodiments.

[0031] Example:

[0032] A metering bin comprises a material bin 1, a weighing hanger 2 is fixedly connected to the bottom of the material bin 1, a weighing box 3 is movably connected to the inside of the weighing hanger 2, the weighing box 3 is limitedly suspended on the weighing hanger 2 by a fixedly connected limit ring 31, the weighing hanger 2 is fixedly connected to the top of the weighing hanger 2 to weigh the suspended weighing box 3, and the bottom of the weighing box 3 is hinged with two closing doors 32, and further comprises:

[0033] A feeding mechanism, which transports the material in the material bin 1 to the weighing box 3;

[0034] A discharge mechanism, which can pour out the material inside the weighing box 3;

[0035] Control mechanism: The control mechanism is used to control the operation of the feeding mechanism and the unloading mechanism.

[0036] By adopting the above technical solution, when using the device, first place the material receiving device directly under the weighing box 3. At this time, the controller 4 is used to set the amount of material to be discharged. Then, the control mechanism is used to control the feeding mechanism to operate. The feeding mechanism can input the material inside the material bin 1 into the weighing box 3. During the discharge process, the weighing hanger 2 connected to the material bin 1 can weigh the material inside the weighing box 3. When the weighing value reaches the set value, the control mechanism controls the feeding mechanism to stop and controls the unloading mechanism to operate. The unloading mechanism can pour out the material inside the weighing box 3. The structure is reasonable, which can improve the efficiency of weighing and discharging, and at the same time improve the accuracy of weighing.

[0037] Specifically, the feeding mechanism includes a first servo motor 5, which is fixedly connected to the center position of the top of the material bin 1. The output shaft of the first servo motor 5 is fixedly connected to a shaft 51, and a spiral blade 52 fixedly connected to one end of the shaft 51 rotates inside the discharge port of the material bin 1.

[0038] By adopting the above-mentioned technical scheme, the material inside the material bin 1 can be controlled for transportation, that is, the first servo motor 5 can drive the shaft 51 to rotate, and the shaft 51 can drive the connected spiral blade 52 to rotate inside the discharge port of the material bin 1. The rotation of the spiral blade 52 can drive the material inside the material bin 1 to be transported, wherein, the slower the rotation speed of the first servo motor 5, the slower the material discharge speed inside the material bin 1, which is convenient for controlling the material discharge speed inside the material bin 1.

[0039] Specifically, the unloading mechanism includes a second servo motor 6, which is fixed on the outer surface of the weighing box 3. The output shaft of the second servo motor 6 is fixedly connected to a screw rod 61, one end of the screw rod 61 is movably connected to a movable seat 62, and the movable seat 62 is threadedly matched with the screw rod 61.

[0040] By adopting the above technical solution, the material inside the weighing box 3 can be controlled for unloading, that is, the second servo motor 6 can drive the screw rod 61 to rotate. Since the screw rod 61 is threadedly matched with the movable seat 62, the movable seat 62 is rotatably connected with the two swing arms 63, and the L-shaped connecting rod 631 rotatably connected to the swing arms 63 is fixed on the closing door 32, so that when the screw rod 61 rotates, it can drive the two closing doors 32 to rotate open or close on the weighing box 3, and then the weighing box 3 can receive the material for weighing, and unload the material after weighing.

[0041] Specifically, the control mechanism includes a controller 4 , which is fixedly connected to the material bin 1 , and controls the operation of the first servo motor 5 and the second servo motor 6 through electric wires.

[0042] By adopting the above technical solution, such as Figure 5 As shown, firstly, a value M is set for the feeding amount through the controller 4, at which time the controller 4 can control the operation of the first servo motor 5, and the first servo motor 5 can drive the material inside the material bin 1 to discharge at a uniform speed. When the controller 4 detects through the measuring scale 21 that the amount of discharge is close to the set value M, at this time the controller 4 can control the first servo motor 5 to slow down, thereby controlling the material inside the material bin 1 to slow down the discharge. When the measuring scale 21 detects that the amount of discharge reaches the set value M, at this time, the controller 4 can control the second servo motor 6 to run, and the second servo motor 6 can control the material inside the weighing box 3 to unload, thereby being able to accurately control the amount of discharge, wherein the weighing box 3 used for material weighing is dehaired before weighing.

[0043] Specifically, a feed hopper 11 is connected through the outer surface of the material bin 1 , and the feed hopper 11 can inject materials into the material bin 1 .

[0044] Specifically, a material level window is provided on the outer surface of the material bin 1 , and the material level window can directly observe the amount of material inside the material bin 1 .

[0045] Specifically, three support columns 12 are fixedly connected to the outer surface of the material bin 1 . The three support columns 12 can support the material bin 1 in mid-air, so as to facilitate the unloading of the material bin 1 .
