[0016] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0017] In the utility model, the first cylinder 3, the second cylinder 13, the motor 8 and the weight sensor 11 are all connected to the external electric control system through wires, wherein the weight sensor 11 can transmit a signal to the electric control system according to the sensed weight, thereby controlling the action of the first cylinder 3 and the second cylinder 13. The above equipment and connection methods are all existing technologies and will not be elaborated on here.

[0018] According to the instruction manual Figure 1-2It can be known that when the utility model is in use, the material is conveyed into the storage hopper 2-1 in the housing 2 through the material conveying assembly. When a certain amount of material is conveyed, the material is stopped, and the first cylinder 3 arranged on the top of the housing 2 is started, so that the telescopic end of the first cylinder 3 drives the connected connecting rod 4 to move vertically downward, and the connecting rod 4 drives the blocking block 5 arranged at the bottom to move together, thereby releasing the blocking of the blocking block 5 on the discharge pipe of the storage hopper 2-1, so that the material in the storage hopper 2-1 falls downward into the weighing hopper 2-2, and the material in the weighing hopper 2-2 The material slides downward into the discharge pipe connected with the material discharge pipe, and then falls onto the weighing plate 12. The weight sensor 11 sends the weight signal sensed by the weight sensor 11 to the control system. When the weighed weight reaches the required value, the telescopic end of the first cylinder 3 contracts, driving the connecting rod 4 and the blocking block 5 to move vertically upward. The blocking block 5 blocks the discharge pipe of the storage hopper 2-1 again, and the second cylinder 13 is started to contract the telescopic end of the second cylinder 13. Since the bottom of the second cylinder 13 is rotated on the fixed rod 14 The fixing rod 14 is fixedly arranged on the inner wall of the shell 2, and the telescopic end of the second cylinder 13 is hinged with the bottom of the blocking plate 10. Therefore, when the telescopic end of the second cylinder 13 is contracted, it can drive the blocking plate 10 to rotate clockwise with the hinged part with the weighing bucket 2-2 as the center, thereby releasing the blocking of the blocking plate 10 on the discharge pipe of the weighing bucket 2-2, so that the material falls into the discharge hopper 2-3, and the material then enters the fused magnesia furnace through the discharge pipe of the discharge hopper 2-3. The pair of limit rings 15 arranged on the fixing rod 14 can The utility model can limit the second cylinder 13 to prevent the second cylinder 13 from being displaced along the fixed rod 14 when rotating; the utility model weighs the material through the weight sensor 11 arranged at the bottom of the weighing plate 12. When the material reaches the specified weight, the first cylinder 3 drives the blocking block 5 to block the discharge pipe of the storage hopper 2-1. The second cylinder 13 drives the blocking plate 10 to rotate to allow the material to enter the electric molten magnesia furnace through the discharge hopper 2-3. There is no need for manual weighing, which saves time and effort for personnel and improves work efficiency.

[0019] There is a possibility of implementation. When conveying materials into the shell 2, first add materials into the upper hopper 6, start the motor 8, the motor 8 drives the conveying screw 9 to rotate, and the conveying screw 9 conveys the materials from the conveying pipe 7 to the storage hopper 2-1.
