Description

Technical Field

[0001] This utility model relates to the field of explosives conveying technology, and in particular to a raw material conveying mechanism for preparing emulsified ammonium nitrate explosives. Background Technology

[0002] Ammonium nitrate explosives (AMF) are mainly suitable for open-pit blasting projects and blasting projects without the risk of methane and mine dust explosions. Products include: powdered AMF, porous granular AMF, heavy AMF, granular adhesive explosives, and thickened granular AMF. The raw materials for emulsified AMF require a specific conveying mechanism for transportation. However, the raw material conveying mechanisms of various emulsified AMF on the market still have various problems.

[0003] The existing raw material conveying mechanism for emulsified ammonium nitrate explosives usually uses a conveyor belt to transport the explosive raw materials. However, the explosive raw materials that are clumped together contain a certain amount of moisture. If the moisture content is high, they are prone to sticking to the conveyor belt or sticking together. This may also cause the explosive raw materials to accumulate together instead of falling naturally, affecting subsequent processing. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. The existing raw material conveying mechanism for emulsified ammonium nitrate explosives usually uses a conveyor belt to transport the explosive raw materials. However, the explosive raw materials that are clumped together contain a certain amount of moisture. If the moisture content is high, they are easy to stick to the conveyor belt or stick together. It may also cause the explosive raw materials to not fall naturally and accumulate together, affecting subsequent processing. Therefore, a raw material conveying mechanism for preparing emulsified ammonium nitrate explosives is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A raw material conveying mechanism for preparing emulsified ammonium nitrate explosive includes a platform and conveying rollers, with two conveying rollers rotatably connected to both ends of the platform, and a conveyor belt sleeved on the conveying rollers;

[0007] The platform is equipped with a drying structure, which includes vertical blocks, a drying box, a perforated plate, connecting rods, a connecting plate, and impact heads. Two vertical blocks are fixedly connected to both ends of the upper surface of the platform. The drying box is fixedly connected to the upper end face of the vertical blocks. The perforated plate is fixedly and slidably connected to the inner side wall of the drying box. Two connecting rods are fixedly connected to both sides of the perforated plate and slidably connected to the drying box. The connecting plate is fixedly connected to the end of the connecting rod away from the perforated plate. Two impact heads are symmetrically arranged and fixedly connected to one end of the connecting plate near the connecting rod.

[0008] Preferably, the drying mechanism further includes a rotating shaft and a motor. Multiple rotating shafts are respectively arranged in an array and installed in the platform body. The motor is fixedly connected to the side wall of the platform body, and the output end of the motor is fixedly connected to one of the rotating shafts.

[0009] Preferably, belts are fitted on the outer surfaces of the plurality of rotating shafts and the two conveying rollers, and reciprocating threads are provided on the plurality of rotating shafts, and push plates are threadedly connected to the rotating shafts.

[0010] Preferably, a protrusion is fixedly connected to the upper end face of the push plate, the protrusion is slidably connected to the conveyor belt, and two slide rods are symmetrically fixedly connected to the end of one of the push plates away from the motor, and a lever is fixedly connected to the end of the slide rod away from the push plate.

[0011] Preferably, elastic rods are fixedly connected to both ends of the upper surface of the lever, and the elastic rods are slidably connected to the connecting plate near the side of the elastic rod.

[0012] Preferably, the lower end face of the drying box and the side wall of the sluice plate are provided with multiple sluice holes, and a return spring is fixedly connected between the connecting plate near the impact head and the drying box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The rotating shaft drives the elastic rod to move the connecting plate, which in turn causes the sprue plate to move back and forth inside the drying box. This causes the sprue plate to continuously overlap and intersect with the holes on the drying box, and causes the impact head to continuously strike the drying box. This disperses the dry powder of the explosive raw materials stored in the drying box onto the conveyor belt, keeping the conveyor belt dry. It also absorbs the moisture at the bottom of any clumps or blocks of explosive raw materials, making it less likely for the explosive raw materials to stick to the conveyor belt.

[0015] 2. The rotating shaft drives the pusher plate to move, causing the protrusion to move horizontally back and forth at the bottom of the conveyor belt. This causes the clumps of explosive raw materials to move slightly on the conveyor belt, preventing the explosive raw materials from staying in one position for too long. It also evenly spreads the dry powder of the explosive raw materials that fall onto the conveyor belt, making it less likely for the explosive raw materials to stick to the conveyor belt. Furthermore, a small amount of dry powder that falls onto the explosive raw materials is shaken off and falls back onto the conveyor belt, preventing excessive dry powder from merging into the raw materials. This ensures that the weight of each piece of explosive raw material is consistent, reducing errors and ensuring quality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A raw material conveying mechanism for preparing emulsified ammonium nitrate explosive includes a platform 1 and conveying rollers 2. The platform 1 is in the shape of a channel steel, and two conveying rollers 2 are rotatably connected to both ends of the platform 1. A conveyor belt 3 is sleeved on the conveying rollers 2.

[0024] The platform 1 is equipped with a drying structure, which includes vertical blocks 4, a drying box 5, a perforated plate 6, a connecting rod 7, a connecting plate 8, and an impact head 9. Two vertical blocks 4 are fixedly connected to both ends of the upper surface of the platform 1. The drying box 5 is fixedly connected to the upper end face of the vertical blocks 4. The drying box 5 stores dry powder of explosive raw materials of the same material as the explosive raw materials; adding it will not change its proportion. The perforated plate 6 is fixedly and slidably connected to the inner side wall of the drying box 5. Multiple perforations are opened on the lower end face of the drying box 5 and the side wall of the perforated plate 6. In a static state, the perforated plate 6 and the dry... The holes on the drying box 5 are staggered to prevent the dry powder of the explosive raw materials from leaking out. Two connecting rods 7 are fixedly connected to both sides of the sprue plate 6, and the connecting rods 7 are slidably connected to the drying box 5. The connecting plate 8 is fixedly connected to the end of the connecting rod 7 away from the sprue plate 6. Two impact heads 9 are symmetrically arranged and fixedly connected to one end of the connecting plate 8 near the connecting rod 7. A return spring 18 is fixedly connected between the connecting plate 8 near the impact head 9 and the drying box 5. The impact head 9 is made of rubber, which is soft and can deform without damaging the drying box 5.

[0025] The drying mechanism also includes a rotating shaft 10 and a motor 11. Multiple rotating shafts 10 are arranged in an array inside the platform 1. The motor 11 is fixedly connected to the side wall of the platform 1. The output end of the motor 11 is fixedly connected to one of the rotating shafts 10. Belts 12 are fitted on the outer surfaces of the multiple rotating shafts 10 and the two conveying rollers 2. Reciprocating threads are provided on the multiple rotating shafts 10. A push plate 13 is threadedly connected to the rotating shaft 10. A protrusion 14 is fixedly connected to the upper end face of the push plate 13. The protrusion 14 is slidably connected to the conveyor belt 3. When the protrusion 14 reciprocates horizontally, it will slightly lift the conveyor belt 3, flatten the dry powder of explosive raw materials sprinkled on the conveyor belt 3, and slightly move the clumps of explosive raw materials so that they do not stick to the conveyor belt 3.

[0026] One of the push plates 13 has two slide rods 15 fixedly connected symmetrically at the end away from the motor 11. A lever 16 is fixedly connected at the end of the slide rod 15 away from the push plate 13. Elastic rods 17 are fixedly connected to both ends of the upper surface of the lever 16. The elastic rods 17 are slidably connected to the connecting plate 8 on the side near the elastic rods 17. The elastic rods 17 will bend when subjected to force and will quickly return to their original state when not subjected to force. The main body of the device is made of materials that do not easily generate static electricity and is connected to a ground wire to conduct away the accumulated charge, making it relatively safe.

[0027] In this invention, during use, simply place the clumps of explosive raw materials onto the conveyor belt 3 and start the motor 11. The motor 11 drives the belt 12 to rotate via the rotating shaft 10. The belt 12 drives the conveyor belt 3 to rotate via the conveyor roller 2, thus conveying the explosive raw materials. Under the action of the reciprocating threads on the rotating shaft 10, the push plate 13 drives the slide rod 15 to move horizontally back and forth. The slide rod 15 drives the deflector plate 16 and the elastic rod 17 to move back and forth. The elastic rod 17 drives the connecting plate 8 to move. When the deflector plate 16 moves from left to right, the elastic rod 17 drives the connecting plate 8 and the connecting rod 7 to move to the right, causing the leaking plate 6 and the connecting plate 8 on the other side to move to the right, compressing the impact head 9 and the return spring 18. The leaking holes on the leaking plate 6 overlap with the leaking holes in the drying box 5, and the dry powder of the explosive raw materials stored in the drying box 5 leaks out from the leaking holes, but the amount leaking out is small and falls onto the conveyor belt 3. When the leaking plate 6 contacts the right edge of the drying box 5, the connecting plate 9... When plate 8 cannot move, elastic rod 17 deforms and passes through the lower end of connecting rod 7. Under the elastic force of return spring 18, connecting plate 8 returns to its original position. When the lever 16 moves from right to left, elastic rod 17 drives connecting plate 8 and connecting rod 7 to move to the left, stretching return spring 18. The leakage hole on the leakage plate 6 overlaps with the leakage hole in the drying box 5. The dry powder of explosive raw materials stored in the drying box 5 leaks out from the leakage hole, but the amount leaking out is small. When leakage plate 6 contacts the left edge of drying box 5, connecting plate 8 cannot move. Elastic rod 17 deforms and passes through the lower end of connecting rod 7. Under the elastic force of return spring 18, connecting plate 8 returns to its original position, driving impact head 9 to impact drying box 5, causing the dry powder of explosive raw materials stored in drying box 5 to leak out from the leakage hole. The amount leaking out is large and falls onto conveyor belt 3, keeping the bottom of conveyor belt 3 dry. The dry powder of explosive raw materials can absorb the moisture on the explosive raw materials.

[0028] The pusher plate 13 drives the protrusion 14 to move back and forth under the conveyor belt 3, causing small protrusions to continuously form on the conveyor belt 3. This flattens the dry powder of explosives falling on the conveyor belt 3 and slightly pushes the raw materials of explosives, preventing them from staying in the same position on the conveyor belt 3 for a long time and making them less likely to stick to the conveyor belt 3. At the same time, the impact and pushing action makes the dry powder of explosives more evenly distributed, and causes a small amount of dry powder of explosives falling on the raw materials to fall back onto the conveyor belt 3 under shaking, preventing too much dry powder from being incorporated into the raw materials. This ensures that the weight of each piece of explosive raw material is consistent, reducing errors and ensuring quality.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
