[0040] In view of the aforementioned problem that the current underground mine hoisting equipment is prone to secondary ore extraction accidents during use, the present application provides a metering hopper system and usage method.

[0041] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0042] To illustrate the specific structure of the metering hopper system provided by the present application, Figure 1 and Figure 2 The structure of the metering hopper system is exemplarily illustrated from different angles. Specifically, Figure 1 a structure diagram of the metering hopper system according to an embodiment of the present application is shown; Figure 2 a working principle diagram of the metering hopper system according to an embodiment of the present application is shown.

[0043] As Figures 1 to 2 commonly shown, the metering hopper system provided by the present application includes a sensor assembly 110, an audible and visual alarm system 130, and a control unit 120, wherein the sensor assembly 110 is configured to detect the position of the ore extraction metering hopper and transmit the detected position information to the control unit; the control unit 120 is configured to send an alarm instruction to the audible and visual alarm system according to the received position information detected by the sensor assembly; and the audible and visual alarm system 130 is configured to send an alarm information according to the received alarm instruction sent by the control unit.

[0044] The sensor assembly 110 includes a first sensor and a second sensor. The first sensor is used to detect whether the ore-feeding hopper is at a preset ore-discharge position and transmits the detected position information to the control unit. The second sensor is used to detect whether the ore-feeding hopper is at a preset full ore position and transmits the detected position information to the control unit.

[0045] The audible and visual alarm system 130 includes an "out-of-position" indicator light, a ore discharge warning bell, and a hoisting indicator alarm light (not shown in the figure). When the control unit 120 receives the position information detected by the first sensor, the control unit sends a command to the audible and visual alarm system; after receiving the command, the "out-of-position" indicator light goes out, and the ore discharge warning bell sounds an ore discharge warning.

[0046] When the control unit receives the location information detected by the second sensor, the control unit sends a command to the audible and visual alarm system; after receiving the command, the ore discharge warning bell stops working, and at the same time the hoisting indicator alarm light issues a hoisting warning.

[0047] In an embodiment of the present invention, the audible and visual alarm system further includes a time relay, wherein the mining warning bell is electrically connected to the time relay. A relay, also known as an electronic relay, is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is commonly used in automatic control circuits. Essentially, it is an "automatic switch" that uses a smaller current to control a larger current, thus playing roles such as automatic adjustment, safety protection, and circuit switching in the circuit.

[0048] exist Figure 2 In the embodiment shown, when the main shaft 2 is running, after the ore-lifting metering hopper 1 leaves the metering station, the non-positioning indicator light remains on. When the ore-lifting metering hopper 1 is lowered to the preset ore-lifting position A, the first sensor detects that the ore-lifting metering hopper 1 has reached position A and sends information to the control unit. Based on the received information, the control unit sends instructions to the non-positioning indicator light and the ore-lifting warning bell respectively, so that the non-positioning indicator light turns off and the ore-lifting warning bell starts to work and issue an alarm message.

[0049] At this time, the operator reminds that the in-place indicator light is in the off state, and the ore drawing warning bell alarm sound is heard, so that the operator knows that the ore drawing measurement bucket 1 has reached the ore drawing preset position A, at this time, the underground operator starts the conveying belt to start ore drawing, and after filling with ore, the ore drawing measurement bucket 1 sinks to position B (full ore preset position) due to the weight of the ore, the first sensor detects that the lifting measurement bucket 1 reaches position B, and sends information to the control unit, and the control unit sends instructions to the ore drawing warning bell and the lifting indicator alarm light according to the received information, so that the ore drawing warning bell stops working, and the lifting indicator alarm light is turned on, reminding the operator that the ore drawing measurement bucket 1 is full and can start ore drawing; At this time, the ore drawing command is locked and cannot be issued again; the operator issues a lifting command, and the ore drawing measurement bucket 1 starts to rise, and after leaving the ore drawing position A, the ore drawing measurement bucket 1 is extinguished, and after leaving the ore drawing area C, the in-place indicator light is on, and the cycle is repeated.

[0050] The above is the specific structure of the measurement bucket system of the present application, and the present application also provides a measurement bucket system using method according to the specific structure of the measurement bucket system, Figure 3 The measurement bucket using method flow according to the embodiment of the present application is shown.

[0057] Specifically, the sound and light alarm system comprises an out-of-position indicator light and a ore-drawing warning buzzer, and the sensor assembly comprises a first sensor and a second sensor.

[0058] When the out-of-position indicator light is in a lighted state, the ore-drawing measuring hopper is lowered to a preset ore-drawing position, wherein the first sensor detects that the ore-drawing measuring hopper is lowered to the preset ore-drawing position and transmits the detected position information to the control unit.

[0059] According to the position information detected by the first sensor, the control unit controls the out-of-position indicator light to be extinguished and controls the ore-drawing warning buzzer to send an alarm information.
