A weighing device 4-1 is installed inside the weighing storage bin 4, and the weighing device 4-1 includes a weighing pan 4-1-1 and a rotating mechanism 4-1-2, and the weighing pan 4-1-1 is mounted on the rotating mechanism. Under the action of 4-1-2, it has the action of rotation.

The initial state of the weighing device 4-1 is that the load-bearing surface of the weighing pan 4-1-1 is placed horizontally upwards, and the rotating mechanism 4-1-2 rotates 360° to dump all the materials and then reset after the materials are weighed.

As shown in Figure 1 and Figure 2, the bottom of the storage tank 1 is provided with a discharge port 1-1, and the discharge port 1-1 is opened or closed by the first switch baffle 1-2, and the first switch baffle 1-2 is adjusted by The device 1-3 is connected and controls the opening and closing of the discharge port 1-1.

The size of the opening of the discharge port 1-1 determines the speed of conveying materials, and the optimal conveying speed of different materials depends on the size of the opening required for different particle sizes, and the adjusting device 1-3 can be adjusted according to the corresponding material type to control the output. The size of the opening of the material port 1-1; when the material quantitative conveying device stops working, the material outlet 1-1 is completely closed, preventing the material in the storage tank 1 from entering the auger conveyor 2-1, and avoiding the auger conveyor 2-1. The residual material in 1 stays hard for a long time and blocks the auger conveyor 2-1.

As shown in Fig. 1 and Fig. 2, the discharge port 1-1 is located directly above the receiving funnel 2-3, and the receiving funnel 2-3 is tightly connected to the discharge port 1-1.

The airtight connection between the receiving funnel 2-3 and the discharge port 1-1 can prevent particle dust of the material from overflowing, and can play a moisture-proof role, slowing down the condensation and hardening of the material due to moisture.

The opening between the temporary storage room 3 and the weighing storage bin 4 can only be opened or closed for use, so the telescopic device 3-2 only controls the second switch baffle 3-1 to fully open and fully close

The weighing device 4-1 has a maximum load, and the materials entering the weighing storage bin 4 from the temporary storage room 3 exceed the maximum load and need to be weighed in batches. The weighing device 4-1 senses that the material has reached the maximum load and then controls it. The telescopic device 3-2 closes the second switch baffle 3-1, waits for the weighing device 4-1 to rotate and dump the material and then controls the telescopic device 3-2 to open the second switch baffle 3-1. , the capacity of the temporary storage room 3 is sufficient to receive and accommodate the materials transmitted by the transmission mechanism 2, without stopping the work of the transmission mechanism 2, the temporary storage room 3 plays a transitional role
