[0042] During implementation, a charging device for smooth blasting that reduces over-excavation and under-excavation is provided, including a charge barrel, a conveyor belt (a first conveying mechanism 300, a second conveying mechanism 400), and a rotating rod 1021; the front end of the base 600 is fixed to the main column 1011, and the rear end of the base 600 is fixed to the two pillars 1031. There are two concave ribs between the two pillars 1031 of the base 600, and a conveyor belt is set on the inner surface of the concave ribs; the left side of the column head on the upper part of the main column 1011 is connected to the circular sleeve 1014, the rotating square shaft is connected to the rotating circular shaft, the rotating circular shaft passes through the circular sleeve 1014 and passes through the column head to be connected to the rotating circular shaft on the right side of the column head, and the outer side of the rotating circular shaft is connected to the rotating rod 1021; the rotating rod 1021 is constrained by the fixed circular shaft and the connecting rod 1022, and the connecting rod 1022 is connected to the rotating rod 1021. The movable plate 1033 is connected to the rotating shaft; the movable plate 1033 is placed in the middle position of the slot plate 1032, and the slot plate 1032 is supported by the pillar 1031 just above the right end of the base 600; the slot plate 1032 contains a groove that is narrow on the outside and wide on the inside. This design facilitates the stable lateral movement of the movable plate 1033 in the slot plate 1032, and the slot plate 1032 is also provided with a "Π"-shaped penetration groove, so that the movable shaft (positioning shaft 1036) can move in the penetration groove; the movable shaft (positioning shaft 1036) is fixedly connected to the crossbeam 201 through the positioning circular shaft, and the upper left end of the crossbeam 201 is connected to the drug injection barrel, the upper part of the drug injection barrel is connected to the drug input barrel, and the lower part of the drug injection barrel is connected to the drug delivery tube 202. The drug delivery tube 202 passes through the crossbeam 201, and its lower end is connected to the drug output barrel 203. By improving upon existing devices, the device boasts the advantages of automatic and uniform filling of emulsion explosives, significantly saving manpower and resources, and improving filling efficiency, thereby effectively resolving the problems and shortcomings of existing technologies. When the emulsion explosive within charging mechanism 200 is low, it can be manually replenished via the feed barrel into the injection barrel. Simultaneously, the blasting energy-gathering tubes on the concave ribs are driven by a conveyor belt to achieve uniform movement. The various devices work together to achieve uniform feeding of the energy-gathering tubes 500, ensuring not only uniform filling of the emulsion explosives but also significantly saving manpower and resources, improving filling efficiency, and reducing overall working hours. Through the uniform circular motion of the rotating rod 1021, the periodic translational motion of the movable plate 1033, the periodic translational lifting motion of the charging mechanism 200, and the uniform motion of the blasting energy-gathering tube on the conveyor belt, uniform feeding of the energy-gathering tube 500 is achieved. The emulsion explosive is not only filled evenly, but also effectively saves a lot of manpower and material resources, improves the filling efficiency, and reduces the overall working hours. It solves the problem that when filling the existing blasting energy-gathering tube with emulsion explosive, manual hand-held filling guns are required to fill the blasting energy-gathering tube with emulsion explosives. This filling method is not only time-consuming and labor-intensive, but also prone to uneven filling, resulting in less than ideal use results.

[0043] Compared with the existing technology, it has the following advantages:

[0044] 1. The charging device of the present invention drives the rotating square shaft to rotate by setting a motor, thereby causing the rotating rod 1021 to rotate in a uniform circular motion, thereby causing the connecting rod 1022 to pull the moving plate 1033 to perform a horizontal back and forth periodic motion on the slot plate 1032, thereby driving the charging mechanism 200 on the crossbeam 201 to move back and forth above the two concave ribs. When the charging mechanism 200 reaches the top of the concave ribs, its height is at its lowest, and the discharge barrel 203 is set to the open state to fill the energy-gathering tube 500 with emulsion explosive. When the charging mechanism 200 moves away, the discharge barrel 203 is set to the closed state, and the cycle continues. At the same time, the energy-gathering tube 500 moves at a uniform speed under the action of the conveyor belt. With the cooperation of various devices, the energy-gathering tube 500 is uniformly fed, and the emulsion explosive is not only uniformly filled, but also effectively saves a lot of manpower and material resources, improves the filling efficiency, and reduces the overall working hours.

[0045] 2. The utility model improves the existing device and has the advantages of being able to automatically fill emulsion explosives and fill them evenly, saving a lot of manpower and material resources, and improving filling efficiency, thereby effectively solving the problems and shortcomings raised by the utility model.
