[0021] The discharge assembly 7 includes a discharge pipe 71, which is connected to the center of the bottom of the hopper 1, and a discharge valve 72 is fixedly installed on the surface of the discharge pipe 71;

[0022] The receiving box 41 is fixedly installed on the top of the weighing sensor 10, and an inclined block 42 is fixedly connected to the bottom of the inner cavity of the receiving box 41. A discharge port 43 is opened at the center of the left bottom of the receiving box 41. A guide seat 44 is fixedly connected to the left side of the receiving box 41 and located between the front and rear sides and the bottom of the discharge port 43. By using the guide seat 44, the baffle plate 66 can be guided and limited, which can facilitate its stable upward and downward sliding movement;

[0023] The material discharge assembly 6 includes a connecting rod 61, which is fixedly welded to the left side of the bottom of the hopper 1, and a connecting plate 62 is fixedly welded to the bottom of the connecting rod 61. The front and rear sides of the bottom of the connecting plate 62 are fixedly connected with connecting ropes 63, and the bottom of the connecting rope 63 is fixedly connected with a cross plate 65. By using the connecting rope 63, a restraining force can be applied to the baffle plate 66, so as to prevent the baffle plate 66 from moving to the left along with the receiving box 41.

[0024] A baffle plate 66 is fixedly connected to the center of the bottom of the horizontal plate 65. The bottom of the baffle plate 66 extends to the inner cavity of the guide seat 44 and slides in contact with the inner wall thereof. Tension springs 64 are fixedly welded to the front and rear sides of the bottom of the horizontal plate 65. By using the tension springs 64, the raised baffle plate 66 can be reset, so that it can automatically reset after the material receiving box 41 is reset. A support plate 67 is fixedly welded to the bottom of the tension spring 64. The right side of the support plate 67 is fixedly welded to the left side of the material receiving box 41.

[0025] The output end of the weighing sensor 10 is unidirectionally signal-connected to the input end of the controller 9 , and the output end of the controller 9 is unidirectionally electrically connected to the input ends of the discharge valve 72 , the display screen 5 and the multi-section electric telescopic rod 2 .

[0026] When in use, the coal powder is placed inside the hopper 1, and then the controller 9 is operated to open the discharge valve 72, so that the coal powder inside the hopper 1 is discharged downward from the discharge pipe 71 and falls into the receiving box 41, and the coal powder inside the receiving box 41 is weighed by the load-bearing sensor 10, and then the weighed weight information is displayed on the surface of the display screen 5 through the controller 9, so that it is convenient for the user to watch. When it reaches the required weight, the discharge valve 72 is controlled by the controller 9 to close, so that the coal powder is no longer discharged, and then the telescopic end of the multi-section electric telescopic rod 2 is controlled to extend, thereby driving the L-shaped plate 3 to move to the left, and then driving the receiving box 4 1 moves to the left, and while the receiving box 41 moves to the left, the blocking plate 66 is driven to move to the left until the connecting rope 63 at the top thereof is in a straightened state, and the blocking plate 66 no longer moves to the left, while the receiving box 41 continues to move to the left. Under the action of the guide seat 44, the blocking plate 66 moves upward, so that the discharge port 43 is opened for discharging. At this time, the tension spring 64 is in a stretched state. When the pulverized coal in the receiving box 41 is completely discharged, the multi-section electric telescopic rod 2 is controlled to reset. At this time, the blocking plate 66 is driven to reset under the action of the tension spring 64, so that the discharge port 43 is blocked again, and then the pulverized coal can continue to be distributed.

[0027] To sum up: the pulverized coal distributor with weighing function, through the cooperation of hopper 1, multi-section electric telescopic rod 2, L-shaped plate 3, material receiving assembly 4, display screen 5, material discharge assembly 6, material discharge assembly 7, support plate 8, controller 9 and weighing sensor 10, solves the problem of lack of weighing function, inability to accurately judge the discharge amount of pulverized coal, and thus inability to achieve accurate pulverized coal supply, inconvenient discharge, and inconvenient discharge of the distributed pulverized coal.
