Description

Technical Field

[0001] This utility model relates to the field of drug loading equipment technology, and in particular to a ground-based drug loading device with a material quantitative conveying mechanism. Background Technology

[0002] Ground-based loading devices, as important material conveying equipment, are widely used in mining, engineering construction, and other fields. Their main function is to efficiently and accurately transport materials from the tank to a designated location. Throughout the entire operation, the operating efficiency of the equipment directly affects the overall progress and cost of the project.

[0003] In practical use, a crucial and frequently performed step is connecting the delivery pipe of the charging device to the external receiving pipe. This connection requires not only a reliable seal to prevent leakage, but also high speed for connection and disconnection to keep pace with modern, rapid construction.

[0004] However, existing ground-based explosive loading devices generally use traditional flange or threaded connections for pipeline connections. While this method can ensure a certain level of sealing, its structural defects are also quite obvious. Operation requires the use of specialized tools such as wrenches to tighten or loosen multiple bolts or rotate multiple threads, a process that is not only time-consuming and labor-intensive but also particularly inconvenient in situations where space is limited or frequent disassembly and reassembly are necessary.

[0005] This slow and cumbersome pipeline connection method has become a significant bottleneck restricting the overall operational efficiency of ground-based explosives loading devices. It results in excessively high time conversion costs between various stages such as preparation, operation, and transfer, failing to meet the growing demand for high-efficiency, fast-paced operations. Therefore, this invention proposes a ground-based explosives loading device with a material quantitative conveying mechanism to address the shortcomings of existing technologies. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a ground-based drug delivery device with a material quantitative conveying mechanism, aiming to improve the problems of existing ground-based drug delivery devices where the material conveying pipelines mostly use traditional connection methods such as threads or flanges, resulting in a cumbersome connection process, time-consuming and labor-intensive, tool-dependent and low-efficiency operation.

[0007] This utility model provides a ground-based medicine delivery device with a material quantitative conveying mechanism, including a medicine delivery pipe and a connecting pipe, with an inner pipe fixedly connected inside the connecting pipe.

[0008] This also includes a quick-connect mechanism. The quick-connect mechanism includes a connecting assembly mounted on the delivery tube and a sliding ring slidably fitted onto the connecting tube. A first fixing ring is fixedly connected to the outer wall of the delivery tube. The connecting assembly includes a fixed fulcrum block and a connecting rod. The fixed fulcrum block is fixedly connected to the first fixing ring, and the connecting rod is rotatably connected to the fixed fulcrum block. A retaining block is fixedly connected to the sliding ring, and the free end of the connecting rod can be engaged with the retaining block. A second fixing ring is fixedly connected to the outer wall of the connecting tube, and a return spring is provided between the sliding ring and the second fixing ring.

[0009] Preferably, the connecting assembly locks and unlocks with the ferrule block via a connecting rod, while the sliding ring, the fixed ring, and the return spring work together to provide elastic preload during connection, ensuring the tightness and reliability of the connection, thus solving the problem of low pipeline connection efficiency in the prior art.

[0010] Preferably, a compression spring is fitted onto the connecting rod to assist in unlocking and separating the connecting rod from the retaining block. The compression spring, through its elastic force, allows the free end of the connecting rod to quickly disengage from the retaining block when the connecting rod is pressed, thereby achieving rapid separation of the pipeline.

[0011] Preferably, the outer diameter of the inner tube is smaller than the inner diameter of the delivery tube, so that when the connecting tube and the delivery tube are connected, the inner tube can be smoothly inserted into the delivery tube to form a preliminary seal. This design avoids leakage of material before it is fully locked, increasing operational safety.

[0012] Preferably, the device also includes a medicine container and a mobile trolley. Support legs are fixedly connected to the bottom of the medicine container. The mobile trolley is equipped with a fixing mechanism for attaching and securing the support legs. This design allows the medicine container to be easily mounted onto the mobile trolley as an independent unit for movement, or detached from it, meeting the needs of different operational scenarios.

[0013] Preferably, the fixing mechanism includes a collar disposed on the top of the movable trolley plate, and the support leg is inserted into the collar. The collar provides a precise insertion guide and initial positioning for the support leg, ensuring convenient fixing.

[0014] Preferably, the fixing mechanism further includes a locking pin and a limiting block. The locking pin is rotatably inserted through the support leg. The limiting block is fixedly connected to the end of the locking pin and can engage with a groove on the inner wall of the collar. By rotating the locking pin, the limiting block can extend from inside the support leg and engage with a pre-reserved groove between the collar and the support leg, forming a secure mechanical lock.

[0015] Preferably, the fixing mechanism further includes a return spring. The return spring is sleeved on the locking pin and is used to push the limiting block into the inner wall slot when the limiting block rotates to the locked position. The return spring ensures the automatic completion of the locking action and the continuous maintenance of the locked state, improving the reliability of the fixing mechanism.

[0016] Preferably, the fixing mechanism further includes a sliding limit ring. The sliding limit ring is sleeved inside the support leg to prevent the locking pin and return spring from excessively disengaging. During the unlocking operation, the sliding limit ring effectively limits the travel of the locking pin, preventing accidental disengagement of components and improving operational safety.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing material conveying pipelines mostly use threaded or flanged connections, which leads to cumbersome, time-consuming, labor-intensive, tool-dependent, and inefficient connection processes. It achieves instantaneous locking and one-click quick separation of pipelines without tools, greatly simplifies the operation process, and significantly improves the efficiency and reliability of loading and docking.

[0018] 2. This utility model solves the problems of complex fixing methods and inconvenient disassembly between the medicine tank and the mobile cart in the prior art, which result in poor flexibility and long preparation time when the equipment needs to be frequently moved and deployed, by designing a fixing mechanism consisting of a rotatable locking post, a limiting block and a return spring. It achieves the technical effect of quick insertion, locking and unlocking between the support leg and the cart plate, ensuring stability during transportation, and greatly improving the efficiency of equipment deployment and transfer.

[0019] 3. This utility model, by organically combining the quick connection mechanism of the pipeline with the quick fixing mechanism of the tank, solves the problem of low overall work efficiency caused by the operational bottlenecks in the two major links of pipeline connection and equipment fixing in the overall operation process of traditional ground loading equipment. It optimizes the entire operation chain from equipment movement and positioning to pipeline connection, realizes efficient and convenient operation of the whole process, and significantly improves the overall efficiency of equipment use and the operating experience.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Reference Figure 1 and Figure 2 This utility model provides a ground-based drug loading device with a material quantitative conveying mechanism, which aims to solve the problems of cumbersome operation and low efficiency of drug loading pipeline connection and inconvenience in moving and fixing the drug loading tank in the prior art.

[0024] like Figure 1 and Figure 2 As shown, a ground-based drug loading device with a material metering conveying mechanism includes a drug loading tank 5 and a support leg 2 fixedly connected to the bottom of the drug loading tank 5. The drug loading tank 5 serves as the material carrier for the entire drug loading equipment, used to store the material to be conveyed. The support leg 2 is used to support the drug loading tank 5 and cooperates with the movable trolley plate 1 to realize the movement and fixation of the drug loading tank 5.

[0025] Reference Figure 1 , Figure 3 and Figure 4The delivery tube 31 serves as the material output end, and a fixing ring 35 is fixedly connected to its outer wall. A fixing fulcrum block 381 is fixedly connected to the fixing ring 35. The fixing fulcrum block 381 provides a stable fulcrum for the connecting assembly 38. The connecting assembly 38 includes a connecting rod 382 and a compression spring 383. The connecting rod 382 is rotatably connected to the fixing fulcrum block 381, and its free end is designed to engage with the clamping block 384 on the connecting tube 32. The compression spring 383 is sleeved on the connecting rod 382 and provides an elastic restoring force when unlocking, pushing the connecting rod 382 out of the clamped state.

[0026] The connecting pipe 32 serves as the material receiving end, and an inner tube 33 is fixedly connected inside it. The outer diameter of the inner tube 33 is smaller than the inner diameter of the delivery pipe 31. When the connecting pipe 32 is inserted into the delivery pipe 31, the inner tube 33 will first enter the delivery pipe 31, forming a preliminary seal to prevent material leakage. A sliding ring 37 is slidably fitted on the outer wall of the connecting pipe 32, and a retaining block 384 is fixedly connected to the sliding ring 37. The shape and size of the retaining block 384 are designed to match the free end of the connecting rod 382, ​​and are used to form a reliable locking engagement with the connecting rod 382.

[0027] A fixing ring 36 is fixedly connected to the outer wall of the connecting pipe 32, and a return spring 34 is provided between the sliding ring 37 and the fixing ring 36. When the connecting pipe 32 is pushed into the delivery pipe 31, the sliding ring 37 slides along the connecting pipe 32, compressing the return spring 34. The elastic force stored in the return spring 34 will continuously apply a thrust to the connection interface after the connection is locked, ensuring the tightness of the connection and the elastic pre-tightening, effectively preventing the connection from loosening and material leakage.

[0028] The quick-connect mechanism 3, through the coordinated operation of the first fixed ring 35, the fixed fulcrum block 381, the connecting rod 382, ​​the compression spring 383, the sliding ring 37, the ferrule block 384, the second fixed ring 36, and the return spring 34, realizes the convenient operation of pressing and locking and quick unlocking between the delivery pipe 31 and the connecting pipe 32, ensuring the rapid and reliable connection of the material conveying pipeline and solving the problem of low efficiency in traditional pipeline connection methods.

[0029] A compression spring 383 is fitted on the connecting rod 382. By pressing the compression spring 383, the free end of the connecting rod 382 can be unlocked and separated from the retaining block 384.

[0030] It also includes a medicine container 5 and a mobile trolley plate 1. The bottom of the medicine container 5 is fixedly connected to a support leg 2. The mobile trolley plate 1 is provided with a fixing mechanism 4 for inserting and fixing the support leg 2. With the cooperation of the fixing mechanism 4, the medicine container 5 can be firmly fixed on the mobile trolley plate 1 or quickly removed from the mobile trolley plate 1.

[0031] The fixing mechanism 4 includes a collar 41 set on the top of the mobile trolley plate 1, and the support leg 2 is inserted into the collar 41 to provide basic positioning and support for the support leg 2.

[0032] The fixing mechanism 4 also includes a locking post 42 and a limiting block 43. The locking post 42 is rotatably inserted through the support leg 2, and the limiting block 43 is fixedly connected to the end of the locking post 42. By rotating the locking post 42, the limiting block 43 can be engaged with the inner wall groove of the collar 41, thereby achieving the locking of the support leg 2 and the collar 41.

[0033] The fixing mechanism 4 also includes a return spring 44, which is sleeved on the locking post 42. When the limiting block 43 is aligned with the inner wall groove by rotation, the elastic force of the return spring 44 will automatically push the locking post 42 and the limiting block 43 into the locking position.

[0034] The fixing mechanism 4 also includes a sliding limit ring 45, which is sleeved inside the support leg 2 to limit the extension stroke of the locking pin 42 and the return spring 44.

[0035] The implementation principle of this application embodiment is as follows: When it is necessary to connect the material pipeline, the connecting pipe 32 is aligned with the drug delivery pipe 31 and pushed in. The inner pipe 33 first inserts into the inside of the drug delivery pipe 31 to form a preliminary seal. As it continues to be pushed in, the sliding ring 37 slides along the axial direction of the connecting pipe 32 and compresses the return spring 34. When the retaining block 384 on the sliding ring 37 moves to the bottom of the connecting rod 382, ​​the connecting rod 382, ​​which is rotated and connected to the fixed fulcrum block 381, will automatically fall into and lock into the retaining block 384 under its own gravity or elastic force, thus completing the locking. At this time, the elastic force continuously applied by the compressed return spring 34 keeps the connecting pipe 32 and the drug delivery pipe 31 in a tight elastic pre-tight state, ensuring the sealing and reliability of the connection. When unlocking, simply press the position of the compression spring 383 on the connecting rod 382 to lift the free end of the connecting rod 382 and disengage it from the retaining block 384. Under the elastic force of the return spring 34, the connecting pipe 32 will automatically pop out, achieving rapid separation.

[0036] When the medicine tank 5 needs to be moved, insert the support leg 2 into the collar 41 at the top of the moving trolley plate 1, then rotate the locking pin 42 to change the limiting block 43 from a horizontal to a vertical position and align it with the slots on the collar 41 and the support leg 2. Under the elastic force of the return spring 44, the locking pin 42 and the limiting block 43 are automatically pushed out, causing the limiting block 43 to simultaneously engage in both slots, completing the quick fixation. To unlock, push the locking pin 42 inward to overcome the elastic force of the return spring 44, causing the limiting block 43 to completely disengage from the slot of the collar 41. Then rotate the locking pin 42 to restore the limiting block 43 to a horizontal position, at which point the support leg 2 can be pulled out of the collar 41. The sliding limit ring 45 ensures that the locking pin 42 will not come out of the support leg 2 throughout the process.
