Description

Technical Field

[0001] This utility model relates to the field of mining production technology, specifically a bag-type loading device. Background Technology

[0002] In scenarios requiring explosives, such as mining and blasting, traditional loading methods have significant drawbacks. Traditional rigid containers (such as metal drums) are heavy, inconvenient to carry, prone to breakage leading to explosive leakage, and require additional counterweights, complicating the process. While simple cloth bags are lightweight, they lack effective partitioning and securing structures, resulting in uneven explosive buildup, inability to integrate counterweights, and safety risks such as poor sealing and explosive spillage. The industry has attempted improvements, such as adding partitions to rigid containers and sealing structures to cloth bags; however, these have been limited by issues such as non-adjustable partitions and insufficient sealing strength. Utility Model Content

[0003] In view of this, the present invention provides a bag-type medicine loading device, which aims to solve the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bag-type medicine loading device, comprising: The explosive bag has an opening at the top and a clamping assembly in the middle. The clamping assembly divides the explosive bag from top to bottom into an explosive filling chamber and a counterweight chamber. The explosive filling chamber is used to hold explosives, and the counterweight chamber is used to hold counterweights. The clamping assembly includes a first clamping plate and a second clamping plate, which are disposed opposite each other on both sides of the explosive bag. The first clamping plate has a first groove, and the second clamping plate has a first protrusion. The first groove and the first protrusion are adapted to each other. The first clamping plate and the second clamping plate are clamped together under the drive of the driving assembly, and the first protrusion extends into the first groove.

[0005] A further improvement of this utility model is that the driving component includes: Two second grooves are symmetrically arranged on the first clamping plate on both sides of the first groove; Two second protrusions are respectively positioned opposite to two second grooves. The second protrusions are adapted to the second grooves. When the second protrusions enter the second grooves, the locking component locks the second protrusions into the second grooves.

[0006] A further improvement of this utility model is that the interior of the second protrusion is hollow, and a through groove is provided on the second protrusion to connect the outside to the interior of the second protrusion. A third groove is provided at the top of the second recess opposite to the through groove, and the third groove is adapted to the through groove. The snap-fit ​​assembly includes: The lifting plate is located inside the second protrusion and moves horizontally under the drive of the moving component; The snap-fit ​​plate is vertically disposed inside the second protrusion. Its lower end is connected to the lifting plate, and its upper end is in the through groove. When the lifting plate moves, the upper end of the snap-fit ​​plate enters or disengages from the third groove.

[0007] A further improvement of this utility model is that the side of the lifting plate near the snap-fit ​​plate is a downwardly inclined surface, and the lower end of the snap-fit ​​plate is provided with a roller that is rolledly connected to the inclined surface.

[0008] A further improvement of this utility model is that the moving component includes a screw, which is rotatably and horizontally disposed inside the second protrusion, with its first end connected to the rotating shaft of the lifting plate and its second end threadedly connected to the second snap-fit ​​plate.

[0009] A further improvement of this utility model is that a rotating wheel is fixedly mounted on the second end of the screw after passing through the second snap-fit ​​plate.

[0010] A further improvement of this invention is that the counterweight is made of stone.

[0011] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows: This invention provides a bag-type explosive loading device that achieves flexible adjustment of the separation position and space through the coordinated design of the clamping component and the driving component. The relative movement of the first and second clamping plates in the clamping component, in conjunction with the movement component within the driving component, drives the lifting plate to adjust the clamping state of the clamping plate. This allows for free adjustment of the space ratio between the explosive loading chamber and the counterweight chamber according to the amount of explosive required in actual operations. Compared with existing technologies, this adjustable separation design breaks free from the constraints of traditional fixed separation layers, flexibly addressing the explosive loading and counterweight requirements in different scenarios such as mining and engineering blasting, significantly improving the adaptability and practicality of the device.

[0012] In this invention, the clamping assembly precisely matches the first groove of the first clamping plate with the first protrusion of the second clamping plate to form a primary sealing and clamping structure. Secondly, the symmetrically arranged second groove and second protrusion in the driving assembly further engage, and together with the clamping action of the clamping plate extending into the third groove within the clamping assembly, a secondary reinforced seal is formed. This double-clamping structure effectively resists vibration and compression during handling, preventing seal loosening. Finally, the close fit between the main body material of the bag and the first and second clamping plates further enhances the overall sealing performance, effectively preventing gunpowder from spilling due to seal failure, while also isolating the counterweight cavity from contact with the charging cavity, preventing static electricity generated by the friction of the counterweight blocks from causing safety risks.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.

[0017] This utility model provides a bag-type medicine loading device, which, in conjunction with the appendix to the instruction manual, is described below. Figure 1 To be continued Figure 3 It is known that the gunpowder bag 10 has an opening, and a clamping assembly 20 is provided in its middle. The clamping assembly 20 divides the gunpowder bag 10 from top to bottom into a gunpowder filling chamber and a counterweight chamber. The gunpowder filling chamber is used to hold gunpowder, and the counterweight chamber is used to hold counterweights. The clamping assembly 20 includes a first clamping plate 21 and a second clamping plate 22, which are arranged opposite each other on both sides of the gunpowder bag 10. The first clamping plate 21 has a first groove 211, and the second clamping plate 22 has a first protrusion 221. The first groove 211 and the first protrusion 221 are adapted to each other. The first clamping plate 21 and the second clamping plate 22 are clamped together under the drive of the driving assembly, and the first protrusion 221 extends into the first groove 211. The counterweight is a stone.

[0018] The operator holds the open end of the propellant bag 10 and inserts a pre-sized counterweight (such as a stone) into the opening. The counterweight falls into the lower counterweight chamber. Then, the clamping component 20 is used to clamp the propellant bag 10 above the counterweight chamber. Next, the operator holds the open end of the propellant bag 10 and slowly pours gunpowder into it. The gunpowder naturally falls into the propellant chamber above the clamping component 20. After everything is in place, the propellant bag 10 is placed into the borehole. Under the action of the counterweight, the propellant bag 10 will naturally fall into the borehole.

[0019] After the counterweight is placed, the clamping assembly 20 clamps the medicine bag 10 above the counterweight cavity in the following way: the operator moves the first clamping plate 21 and the second clamping plate 22 relative to each other, so that the first protrusion 221 extends into the first groove 211, achieving initial engagement. At this time, the medicine cavity and the counterweight cavity are completely separated, forming two independent spaces, and the driving assembly can make the first clamping plate 21 and the second clamping plate 22 finally engage together.

[0020] Through the coordinated design of the clamping assembly 20 and the drive assembly, flexible adjustment of the separation position and space is achieved. The relative movement of the first clamping plate 21 and the second clamping plate 22 in the clamping assembly 20, in conjunction with the movement component in the drive assembly driving the lifting plate 31 to adjust the clamping state of the clamping plate 32, allows for free adjustment of the space ratio between the charging chamber and the counterweight chamber according to the amount of gunpowder required in actual operations. Compared with existing technologies, this adjustable separation design breaks free from the constraints of traditional fixed separation layers and can flexibly meet the charging and counterweight requirements in different scenarios such as mining and engineering blasting, greatly improving the adaptability and practicality of the device.

[0021] As one embodiment, in conjunction with the appendix to the specification Figure 2 To be continued Figure 3It is known that the drive assembly includes two second grooves 212, which are symmetrically arranged on the first clamping plates 21 on both sides of the first groove 211; two second protrusions 222 are respectively arranged opposite to the two second grooves 212, and the second protrusions 222 are adapted to the second grooves 212. When the second protrusions 222 enter the second grooves 212, the clamping assembly 30 clamps the second protrusions 222 with the second grooves 212. The second protrusion 222 is hollow inside and has a through groove 223 connecting the outside to the inside of the second protrusion 222. A third groove is located at the top of the second recess 212 opposite to the through groove 223, and the third groove is adapted to fit the through groove 223. The locking assembly 30 includes a lifting plate 31, disposed inside the second protrusion 222, and moved horizontally under the drive of the moving assembly; and a locking plate 32, vertically disposed inside the second protrusion 222, with its lower end connected to the lifting plate 31 and its upper end in the through groove 223. When the lifting plate 31 moves, the upper end of the locking plate 32 enters or disengages from the third groove. The side of the lifting plate 31 near the locking plate 32 is a downwardly sloping surface 311, and the lower end of the locking plate 32 is provided with a roller 321 that is rollingly connected to the sloping surface 311. The moving assembly includes a screw 33, rotatably and horizontally disposed inside the second protrusion 222, with its first end connected to the rotating shaft of the lifting plate 31 and its second end threadedly connected to the second locking plate 32. The second end of the screw 33 passes through the second snap-fit ​​plate 32 and is fixed with a rotating wheel 34.

[0022] Holding the first clamping plate 21 and the second clamping plate with both hands respectively, slowly push them closer together so that the two second protrusions 222 on the second clamping plate 22 are precisely aligned with the two second grooves 212 on the first clamping plate 21. Continue applying force until the second protrusions 222 are completely inserted into the second grooves 212. At the same time, observe the first groove 211 of the first clamping plate 21 and the first protrusion 221 of the second clamping plate 22 to ensure that they fit synchronously, laying the foundation for subsequent sealing and engagement. Hold the clamping assembly 20 with one hand for stability, and hold the rotating wheel 34 at the end of the screw 33 with the other hand. The rotation of the rotating wheel 34 will drive the screw 33 horizontally. The second protrusion 222 moves internally, thereby pushing the lifting plate 31 to slide horizontally within the second protrusion 222. As the lifting plate 31 moves horizontally, its downwardly inclined slope 311 near the snap-fit ​​plate 32 makes rolling contact with the roller 321 at the lower end of the snap-fit ​​plate 32. The inclined structure of the slope 311 generates an upward pushing force on the roller 321. Under this force, the snap-fit ​​plate 32 moves upward in the vertical direction, and its upper end gradually extends out from the through groove 223 of the second protrusion 222 and is precisely embedded in the third groove at the top of the second groove 212, realizing the snap-fit ​​fixation of the second protrusion 222 and the second groove 212. Continue to rotate the rotating wheel 34 until obvious resistance is felt. At this time, the first snap-fit ​​plate 21 and the second snap-fit ​​plate 22 form a double fixing structure through the initial snap-fit ​​of "first protrusion 221-first groove 211" and the reinforced snap-fit ​​of "second protrusion 222-second groove 212 + snap-fit ​​plate 32-third groove".

[0023] The clamping assembly 20 precisely matches the first groove 211 of the first clamping plate 21 with the first protrusion 221 of the second clamping plate 22 to form a primary sealing and clamping structure. Secondly, the second groove 212 and the second protrusion 222, which are symmetrically arranged in the drive assembly, further engage with each other. Together with the clamping action of the clamping plate 32 in the clamping assembly 30 extending into the third groove, a secondary reinforced seal is formed. The double clamping structure can effectively resist vibration and compression during transportation and prevent the seal from loosening. Finally, the close fit between the main body material of the bag and the first clamping plate 21 and the second clamping plate 22 further improves the overall sealing performance, which can effectively prevent gunpowder from spilling due to seal failure. At the same time, it isolates the contact between the counterweight cavity and the charging cavity and avoids the safety risks caused by static electricity generated by the friction of the counterweight.
