Abstract
Description
Technical Field
[0001] This invention relates to the field of conveying mechanism technology, and in particular to a conveying mechanism for a drug loading trolley. Background Technology
[0002] In blasting engineering fields such as mining and tunneling, the charging trolley is the core equipment for achieving automated and large-scale charging operations. The performance of its conveying mechanism directly determines the charging efficiency, accuracy, and operational safety. Currently, the conveying mechanisms of charging trolleys on the market are mainly designed for powdered and granular explosives, and generally adopt the basic process of storing, conveying, and injecting explosives. However, in practical applications, due to the limitations of the mechanism design, there are still many technical pain points that urgently need to be addressed.
[0003] Explosives are prone to clumping and bridging within storage tanks, severely impacting the smooth flow of explosives. Existing charging trolleys often use storage tanks equipped with a single rotating stirring rod with a fixed stirring trajectory, capable of only disturbing a localized area of explosives and failing to achieve uniform dispersion of the explosives throughout the tank. For highly hygroscopic powdered explosives or granular explosives with uneven particle size, prolonged storage or settling can easily lead to the formation of dense clumps. These clumps can clog delivery pipelines and valves, causing delivery interruptions. This not only reduces charging efficiency but also requires manual shutdown for cleaning, increasing safety risks during downhole operations. Furthermore, the electronic valve connecting the storage tank and delivery pipeline is a critical control point for explosive delivery and a high-risk area for blockages. Traditional charging trolleys lack active anti-blocking and unblocking mechanisms. When explosives accumulate at the opening of the electronic valve and form bridges, they can only be handled by manual disassembly and cleaning or by high-pressure airflow backflushing. The former is cumbersome and time-consuming, while the latter is prone to causing explosive dust to spread, which not only pollutes the working environment but also poses an explosion hazard. Therefore, this application proposes a conveying mechanism for charging trolleys. Summary of the Invention

[0006] Optionally, the dispersing mechanism includes a rotating shaft rotatably installed inside the medicine storage tank, a first gear fixedly installed on the rotating shaft, a connecting plate fixedly installed at the bottom of the rotating shaft, a stirring rod rotatably installed on the connecting plate, a second gear fixedly installed at one end of the stirring rod, the second gear meshing with the first gear, a plurality of stirring blocks arranged at equal intervals fixedly installed on the stirring rod, an upper plate fixedly installed inside the medicine storage tank, a first electronic valve provided on the upper plate, a bottom plate provided at the bottom of the medicine storage tank, a second electronic valve provided on the bottom plate, and a clearing mechanism for clearing the first electronic valve and the second electronic valve inside the medicine storage tank.
[0007] Optionally, the unblocking mechanism includes a first mounting frame fixedly installed inside the medicine storage tank. Guide blocks are symmetrically slidably installed inside the first mounting frame. A limit block is fixedly installed on one side of the guide block. A guide plate is hinged to the limit block. A cylinder is fixedly installed inside the medicine storage tank. An mounting plate is fixedly installed on the piston rod of the cylinder. One end of the guide plate is hinged to the mounting plate. A fixing rod is fixedly installed on one side of the limit block. An unblocking block is fixedly installed at one end of the fixing rod. The unblocking block is conical and located between the first electronic valve and the second electronic valve.
[0008] Optionally, a blower is fixedly installed on the working plate, and a guide pipe is fixedly installed at one end of the blower. One end of the guide pipe is connected to the drug delivery pipe. A turntable is rotatably installed on the working plate, and a second mounting frame is fixedly installed on the turntable. A slider is slidably installed on the second mounting frame, and a threaded rod is rotatably installed inside the second mounting frame. The threaded rod is threadedly connected to the slider. A third gear is rotatably installed on one side of the slider, and a drug injection pipe is fixedly installed on the third gear. One end of the drug injection pipe is connected to the drug delivery pipe. A fourth gear is rotatably installed on the second mounting frame, and the fourth gear meshes with the third gear.
[0009] Optionally, a first valve is provided on the drug delivery tube, and a second valve is provided on the guide tube.
[0010] Optionally, a connecting hose is fixedly installed at one end of the drug delivery tube, and one end of the connecting hose is fixedly connected to the drug injection tube, and a connecting cover is fixedly installed on the drug injection tube.
[0011] Optionally, a first motor is fixedly installed inside the medicine storage tank, and the output shaft of the first motor is fixedly connected to the rotating shaft.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention uses a first motor to drive a rotating shaft, which in turn causes the connecting plate to revolve. Simultaneously, the meshing relationship between the first and second gears forces the stirring rod to rotate synchronously on the connecting plate. The stirring block achieves a compound motion with the stirring rod, which can thoroughly disperse the gunpowder in the storage tank without any dead angles, significantly improving the flowability of the gunpowder and preventing delivery interruptions caused by clumping from the source.
[0016] Furthermore, the mounting plate is driven to move horizontally and reciprocally by a cylinder. The guide plate is driven to slide within the first mounting frame by hinge transmission. This allows the conical unblocking block to perform vertical reciprocating insertion and removal unblocking at the openings of the first and second electronic valves. The conical structure can effectively break the bridging phenomenon of gunpowder accumulation, improve the flowability of gunpowder, and prevent gunpowder blockage.
[0017] Furthermore, a third motor drives the turntable to rotate, achieving 360° horizontal adjustment; a second motor drives the threaded rod to lift and lower the slider, achieving vertical adjustment; and a fourth motor drives the fourth gear to mesh with the third gear, achieving angle adjustment of the injection tube itself. The three adjustment mechanisms work together to adapt to boreholes of any angle and depth.
[0018] This invention achieves thorough dispersion of gunpowder before loading and avoids gunpowder blockage during loading, thereby improving loading efficiency and the applicability of the equipment. Attached Figure Description

[0027] Example 1 like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a conveying mechanism for a charging trolley, including a working plate 1 for mounting on the charging trolley, and a gunpowder storage tank 3 fixedly mounted on the working plate 1 for storing gunpowder. A support rod 2 is fixedly mounted on the working plate 1 and is fixedly connected to the gunpowder storage tank 3. The gunpowder storage tank 3 is provided with a charging port 4, and a delivery pipe 25 is fixedly mounted at the bottom of the gunpowder storage tank 3. A gunpowder injection pipe 30 is fixedly mounted at one end of the delivery pipe 25, and a gunpowder injection port 31 is provided at one end of the injection pipe 30. A gunpowder dispersion mechanism is provided inside the gunpowder storage tank 3.
[0028] like Figure 2 , Figure 3 and Figure 5As shown, the dispersing mechanism includes a rotating shaft 6 rotatably installed inside the medicine storage tank 3. A first gear 7 is fixedly installed on the rotating shaft 6. A connecting plate 8 is fixedly installed at the bottom of the rotating shaft 6. A stirring rod 9 is rotatably installed on the connecting plate 8. A second gear 10 is fixedly installed at one end of the stirring rod 9, and the second gear 10 meshes with the first gear 7. Multiple stirring blocks 11 arranged at equal intervals are fixedly installed on the stirring rod 9. An upper plate 12 is fixedly installed inside the medicine storage tank 3. A first electronic valve 13 is installed on the upper plate 12. A bottom plate 22 is installed at the bottom of the medicine storage tank 3. A second electronic valve 23 is installed on the bottom plate 22. A first motor 5 is fixedly installed inside the medicine storage tank 3. The output shaft of the first motor 5 is fixedly connected to the rotating shaft 6. When the first motor 5 is started, the output shaft of the first motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the first gear 7 and the connecting plate 8 to rotate. The first gear 7 drives the second gear 10 to rotate. The second gear 10 drives the stirring rod 9 to rotate on the connecting plate 8. The stirring block 11 on the stirring rod 9 fully disperses the gunpowder, improving its fluidity and preventing it from clumping and affecting the transport. The rotation of the connecting plate 8 drives the stirring rod 9 to revolve around the rotating shaft 6, allowing the stirring rod 9 to both rotate on its own axis and revolve around the shaft, improving the dispersing effect of the stirring block 11 on the gunpowder and fully dispersing the gunpowder inside. The first motor 5 drives the rotating shaft 6 to rotate, causing the connecting plate 8 to revolve around the shaft. At the same time, the meshing relationship between the first gear 7 and the second gear 10 forces the stirring rod 9 to rotate synchronously on the connecting plate 8. The stirring block 11 achieves a compound motion with the stirring rod 9, which can fully disperse the gunpowder in the storage tank 3 without dead angles, significantly improving the fluidity of the gunpowder and preventing the interruption of transport caused by clumping from the source. The storage tank 3 is equipped with a dredging mechanism for unblocking the first electronic valve 13 and the second electronic valve 23.
[0029] Example 2 like Figure 2 , Figure 3 and Figure 6As shown, the unblocking mechanism includes a first mounting frame 16 fixedly installed inside the medicine storage tank 3. Guide blocks 17 are symmetrically slidably installed inside the first mounting frame 16. A limit block 18 is fixedly installed on one side of the guide block 17, and a guide plate 19 is hinged to the limit block 18. A cylinder 14 is fixedly installed inside the medicine storage tank 3. A mounting plate 15 is fixedly installed on the piston rod of the cylinder 14. One end of the guide plate 19 is hinged to the mounting plate 15. A fixing rod 20 is fixedly installed on one side of the limit block 18, and an unblocking block 21 is fixedly installed on one end of the fixing rod 20. The unblocking block 21 is tapered and located between the first electronic valve 13 and the second electronic valve 23. When unblocking is required between the first electronic valve 13 and the second electronic valve 23, the cylinder 14 is activated, and the piston rod of the cylinder 14 drives the mounting plate 19 to move. The mounting plate 15 reciprocates horizontally in the horizontal direction. The mounting plate 15 drives the guide plate 19 to move. The guide plate 19 drives the guide block 17 on one side to reciprocate horizontally within the first mounting frame 16. The guide block 17 drives the unblocking block 21 on the limiting block 18 to reciprocate vertically. The unblocking block 21 continuously unblocks the openings of the first electronic valve 13 and the second electronic valve 23 to prevent gunpowder from accumulating and being unable to be conveyed downwards. The mounting plate 15 is driven to reciprocate horizontally by the cylinder 14. The guide plate 19 is driven to slide within the first mounting frame 16 by the hinge transmission. This allows the conical unblocking block 21 to reciprocate vertically through the openings of the first electronic valve 13 and the second electronic valve 23. The conical structure can effectively break the bridging phenomenon of gunpowder accumulation.
[0030] Example 3 like Figure 2 , Figure 3 and Figure 7As shown, a blower 28 is fixedly installed on the working plate 1. A guide pipe 26 is fixedly installed at one end of the blower 28, and one end of the guide pipe 26 is connected to the delivery pipe 25. A turntable 35 is rotatably installed on the working plate 1. A second mounting frame 34 is fixedly installed on the turntable 35. A slider 38 is slidably installed on the second mounting frame 34. A threaded rod 37 is rotatably installed inside the second mounting frame 34 and is threadedly connected to the slider 38. A third gear 39 is rotatably installed on one side of the slider 38. A gunpowder injection pipe 30 is fixedly installed on the third gear 39, and one end of the gunpowder injection pipe 30 is connected to the delivery pipe 25. A fourth gear 40 is rotatably installed on the second mounting frame 34. The fourth gear 40 meshes with the third gear 39, and the gunpowder conveyed downwards enters the delivery pipe 25. Inside the gunpowder tube 25, the blower 28 is started, drawing outside air into the gunpowder delivery tube 25. The air then transports the gunpowder in the delivery tube 25 to the injection tube 30, and then discharges it through the injection port 31. The gunpowder is then loaded into the hole to be loaded. In conjunction with rotating the threaded rod 37, the threaded rod 37 drives the slider 38 to move up and down on the second mounting frame 34. The slider 38 drives the injection tube 30 to move. In conjunction with rotating the fourth gear 40, the fourth gear 40 drives the third gear 39 to rotate. The third gear 39 drives the injection tube 30 to rotate. In conjunction with rotating the turntable 35, the turntable 35 drives the second mounting frame 34 to rotate. The second mounting frame 34 drives the injection tube 30 to rotate, allowing for all-around adjustment of the position of the injection port 31, improving the applicability of the equipment.
[0031] like Figure 2-3 As shown, a first valve 24 is provided on the drug delivery tube 25, a second valve 27 is provided on the guide tube 26, a connecting hose 29 is fixedly installed at one end of the drug delivery tube 25, and one end of the connecting hose 29 is fixedly connected to the injection tube 30. A connecting cover 32 is fixedly installed on the injection tube 30. A third motor 36 is fixedly installed at the bottom of the working plate 1, and the output shaft of the third motor 36 is fixedly connected to the turntable 35. A second motor 33 is fixedly installed on the second mounting frame 34, and the output shaft of the second motor 33 is fixedly connected to the threaded rod 37. A fourth motor 41 is fixedly installed on one side of the second mounting frame 34, and the output shaft of the fourth motor 41 is fixedly connected to the fourth gear 40.
[0032] Working principle: The first motor 5 is started, and its output shaft drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the first gear 7 and the connecting plate 8 to rotate. The first gear 7 drives the second gear 10 to rotate, and the second gear 10 drives the stirring rod 9 to rotate on the connecting plate 8. The stirring block 11 on the stirring rod 9 fully disperses the gunpowder, improving its fluidity and preventing clumping that could affect delivery. The rotation of the connecting plate 8 causes the stirring rod 9 to revolve around the rotating shaft 6, allowing it to both rotate on its own axis and revolve around the shaft, thus improving the dispersion effect of the stirring block 11 on the gunpowder and fully dispersing the gunpowder inside. When it is necessary to unclog the first electronic valve 13 and the second electronic valve 23, the cylinder 14 is started. The piston rod of the cylinder 14 drives the mounting plate 15 to reciprocate horizontally. The mounting plate 15 drives the guide plate 19 to move, and the guide plate 19 drives the guide block 17 on one side to reciprocate horizontally within the first mounting frame 16. The guide block 17 drives the limit block 18... The unblocking block 21 performs a vertical reciprocating motion, continuously unblocking the openings of the first electronic valve 13 and the second electronic valve 23 to prevent gunpowder from accumulating and being unable to be conveyed downwards. The downward-conveyed gunpowder enters the delivery pipe 25. The blower 28 is started, drawing outside air into the delivery pipe 25. The air conveys the gunpowder in the delivery pipe 25 to the injection pipe 30, and then discharges it from the injection port 31 to load the hole to be loaded. In conjunction with the rotation of the threaded rod 37, the threaded rod 37 drives the slider 38 to move up and down on the second mounting frame 34. The slider 38 drives the injection pipe 30 to move. In conjunction with the rotation of the fourth gear 40, the fourth gear 40 drives the third gear 39 to rotate. The third gear 39 drives the injection pipe 30 to rotate. In conjunction with the rotation of the turntable 35, the turntable 35 drives the second mounting frame 34 to rotate. The second mounting frame 34 drives the injection pipe 30 to rotate, allowing for all-round adjustment of the position of the injection port 31, improving the applicability of the equipment.
