Description

Technical Field

[0001] This utility model relates to the field of explosives loading technology, and more specifically to an explosives mixing and loading device. Background Technology

[0002] Blasting is a common construction method in fields such as mining, tunnel construction, and earthwork engineering. To achieve good blasting results, it is necessary to precisely control the amount and position of explosives. This has spurred the research and development and application of charging devices. Traditional manual charging methods are not only time-consuming and labor-intensive, but also pose significant safety hazards. Charging devices, through mechanized operation, accurately and quickly place explosives into the blast hole, which can significantly improve charging efficiency, reduce labor costs, and avoid safety hazards.

[0003] Existing charging devices often struggle to fully mix different types of explosives when handling mixed explosives, which directly affects blasting effectiveness and safety. Since each type of explosive has different characteristics, uneven mixing can lead to unstable explosion reactions, thereby reducing work efficiency and increasing safety hazards.

[0004] Secondly, when using existing equipment to fill explosives into the borehole, the delivery tube is prone to deviation. This deviation not only affects the filling speed and quality, but may also cause some areas to be inadequately filled, thus affecting the overall blasting performance.

[0005] To address the aforementioned problems, this application provides an explosive mixing and charging device. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an explosive mixing and charging device to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: an explosive mixing and charging device, including a main component and a feeding component installed on the side wall of the main component, a transmission component installed on the main component, a mixing component installed on the transmission component, a telescopic component installed below the main component, and a fixing component installed below the telescopic component;

[0008] Preferably, the main component includes a medicine container, a support frame, and support feet, wherein the medicine container is fixedly installed on the support frame, and support feet are fixedly installed at the four corners of the support frame.

[0009] Preferably, the feeding assembly includes a feeding pipe and a feeding hopper, wherein the feeding pipe is fixedly installed on the side wall of the charging barrel and communicates with its inner cavity, and the feeding hopper is fixedly installed above the feeding pipe and communicates with its inner tube. In this case, gunpowder of different specifications can be poured into the charging barrel through each feeding pipe and feeding hopper.

[0010] Preferably, the transmission assembly includes a rotary motor, a first bevel gear, a second bevel gear, a transmission rod, a first transmission wheel, a fixed block, a conveyor belt, a second transmission wheel, and a rotating disk. The rotary motor is fixedly mounted on the top of the medicine-filling barrel. The rotary motor's transmission shaft is fixedly sleeved on the first bevel gear, which meshes with the second bevel gear. The second bevel gear is fixedly sleeved on the upper end of the transmission rod. The first transmission wheel is fixedly sleeved on the middle section of the transmission rod. The lower end of the transmission rod is rotatably sleeved on the fixed block, which is fixedly mounted on the side wall of the medicine-filling barrel. The rotating disk is rotatably sleeved on the upper inner wall of the medicine-filling barrel. The second transmission wheel is fixedly sleeved on the upper part of the rotating disk. The conveyor belt winds between the second transmission wheel and the first transmission wheel. At this time, the rotary motor's transmission shaft drives the first bevel gear, and the meshing action between the first and second bevel gears drives the first transmission wheel to rotate around the axis of the transmission rod. Subsequently, the first transmission wheel drives the second transmission wheel, thereby driving the rotating disk to rotate.

[0011] Preferably, the mixing assembly includes a fixed rod, a first gear, a second gear, a rotating rod, and a stirring blade. One end of the fixed rod is movably sleeved on the second transmission wheel and the rotating disk and fixedly installed on the inner wall of the top of the charging barrel. The other end is fixedly sleeved on the first gear, which meshes with the second gear. The second gear is fixedly sleeved on the rotating rod. One end of the rotating rod is rotatably sleeved below the rotating disk, and the other end is fixedly connected to the stirring blade. At this time, under the transmission action, the rotating rod installed at the bottom of the rotating disk begins to rotate around the fixed rod. Under the meshing action between the second gear and the first gear, the rotating rod and the stirring blade are driven to rotate around the axis of the rotating rod, so as to fully mix the gunpowder inside the charging barrel.

[0012] Preferably, the telescopic assembly includes a first feeding pipe, a discharge valve, a second feeding pipe, a fixed connecting block, and a telescopic motor. The upper end of the first feeding pipe is fixedly installed at the bottom of the medicine barrel and communicates with its inner cavity. The discharge valve is fixedly installed on the first feeding pipe. The second feeding pipe is movably sleeved on the first feeding pipe. The telescopic motor is fixedly installed at the bottom of the medicine barrel. The telescopic shaft of the telescopic motor is fixedly connected to the fixed connecting block. The fixed connecting block is fixedly installed on the side wall of the second feeding pipe. At this time, the telescopic shaft of the telescopic motor can drive the fixed connecting block and the second feeding pipe to move downward.

[0013] Preferably, the fixing assembly includes a pressure plate, a fixed plate, a rotating column, and a pusher plate. The pressure plate is fixedly sleeved on the second feeding pipe, the fixed plate is movably sleeved on the second feeding pipe, the pressure plate is movably engaged with the fixed plate through the bottom column head, the middle section of the rotating column is rotatably engaged on the fixed plate, and the lower end of the rotating column is rotatably engaged with the pusher plate. During the downward movement of the second feeding pipe, the fixed plate is moved above the blast hole. Under the action of the second feeding pipe, the pressure plate begins to move downward relative to the fixed plate. The rotating column begins to rotate under the push of the pressure plate, thereby causing the pusher plate to press tightly against the inner wall of the blast hole, thus fixing the fixing assembly inside the blast hole.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] When using the device, gunpowder of different specifications is poured into the charging barrel through the feed pipe and feed hopper. The rotating motor drives the first bevel gear, and through the gear meshing and the transmission relationship between various components, the stirring blade is driven to rotate, which fully mixes the gunpowder inside the charging barrel. During charging, the telescopic motor moves the second feed pipe downward, and the pressure plate begins to move downward relative to the fixed plate under the action of the second feed pipe. The rotating column begins to rotate under the push of the pressure plate, which in turn drives the push plate to stick tightly to the inner wall of the borehole, thereby fixing the fixing component in the borehole and preventing the nozzle from shifting during charging.

Under the action of the second feeding pipe 503, the pressure plate 601 begins to move downward relative to the fixed plate 602. The rotating column 603 begins to rotate under the push of the pressure plate 601, which in turn drives the push plate 604 to stick tightly to the inner wall of the blast hole, thereby fixing the fixing component 6 inside the blast hole. At this time, the first feeding pipe 501 opens, and the explosive enters the blast hole through the first feeding pipe 501 and the second feeding pipe 503.
