The cleaning groove 3-1 is fixed at the rear end of the air source box 2-2. The upper end of the cleaning groove 3-1 is provided with an opening. The fixed end of the spring telescopic rod 3-2 is fixedly connected to the inner bottom surface of the cleaning groove 3-1.

[0023] Preferably, belt conveyor 1-1 and belt conveyor 2-4-4 are TD75 general-purpose fixed belt conveyors. This is an existing technology that is purchased externally, so it will not be described in detail here.

[0024] Preferably, the air pump in the air source box 2-2 is model EMPGA-380V-08, which is an existing technology that uses external purchases and will not be described in detail here.

[0025] Preferably, cylinders 2-7 are national standard cylinders QGA / QGB series, which are currently outsourced and will not be elaborated further.

[0026] Preferably, a counter of model HQ-210 can be installed on the chain plate 1-2. This is existing technology and is purchased externally, so it will not be described in detail. The counter is connected to the PLC, and the PLC is connected to the air pump. The PLC can modify the parameters via a computer. The emulsion explosive is conveyed by the chain plate 1-2 and falls into the collection tank 2-4-2 for feeding. When the counter records the number of times the chain plate 1-2 moves to reach the set parameter, the PLC controls the air pump to drive the cylinder 2-7 to actuate and rotate the feeding unit 2-4 to transport the emulsion explosive to the next process. At the same time, the PLC controls the belt conveyor 1-1 to stop. The above method can also achieve quantitative feeding. Then, the PLC controls the feeding unit 2-4 to reset and the belt conveyor 1-1 to start the next feeding.

[0027] The working principle of this utility model is as follows:

[0028] The emulsion explosive is placed on the chain plate 1-2. This device is connected to an external power source. Starting the belt conveyor 1-1 moves the chain plate 1-2, which in turn moves the emulsion explosive on the chain plate 1-2. The emulsion explosive falls into the collection trough 2-4-2 as the chain plate 1-2 moves. Simultaneously, the scraper 2-1 scrapes the emulsion explosive off the chain plate 1-2, preventing it from adhering and affecting the accuracy of the feeding. Powering the motor 3-5 drives the roller brush 3-4 to rotate via the belt 3-6. The rotation of the roller brush 3-4 further cleans the chain plate 1-2, preventing corrosion caused by emulsion explosive residue. The impurities brushed off by the roller brush 3-4 fall into the cleaning trough 3-1 for collection. The roller brush 3-4 can be moved by the spring telescopic rod 3-2. -4 is always pressed against the chain plate 1-2, which can prevent the roller brush 3-4 from wearing and creating gaps between it and the chain plate 1-2, thus affecting the cleaning effect. The rotation direction of the roller brush 3-4 is opposite to the movement direction of the chain plate 1-2. Through the reverse force, the chain plate 1-2 can be cleaned more thoroughly. When the emulsion explosive in the collection tank 2-4-2 reaches the amount for the next process, the air pump starts and controls the cylinder 2-7 to retract. The retraction of the cylinder 2-7 drives the horizontal plate 2-4-1 to rotate clockwise around the support frame 2-3, thus flipping it over. At this time, the emulsion explosive in the collection tank 2-4-2 falls onto the belt conveyor 2-4-4. The belt conveyor 2-4-4 is powered on to move the emulsion explosive to the next process. Then, the cylinder 2-7 is extended and reset to allow for the next feeding.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
