Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of resin anchoring agent production, and more specifically, to a batching device for a mining resin anchoring agent. Background Technology

[0002] Mining resin anchoring agents are core materials for mine roadway support. The accuracy and continuity of their batching directly determine key properties such as the anchoring agent's bonding strength and setting speed, thus affecting the safety and efficiency of support construction. With the development of large-scale and efficient mining operations, the shortcomings of traditional batching devices have become increasingly apparent: existing devices concentrate the raw material proportioning and mixing processes within the same equipment, lacking independent pre-batching and temporary storage structures. This makes it impossible to prepare the next batch of raw materials in advance during the mixing of the current batch, resulting in interruptions in the processing flow and poor continuity.

[0003] The drawbacks of traditional equipment are particularly prominent: after the previous batch of materials is mixed, the machine needs to be stopped to clean the equipment, add raw materials again, and adjust the ratio. The whole process takes a long time and causes a production downtime. Frequent shutdowns not only reduce overall production efficiency, but may also affect the uniformity of raw material mixing due to equipment start-up and shutdown fluctuations, which in turn leads to unstable performance of the anchoring agent. For large-scale support projects, discontinuous processing will lead to insufficient supply of anchoring agent and delay the construction progress. In addition, the equipment is idle when the machine is stopped for batching, resulting in low resource utilization and failing to meet the requirements of efficient and continuous operation in mining construction.

[0004] Therefore, developing a batching device for mining resin anchoring agents that can prepare materials in advance and ensure continuous processing has become an urgent need to solve the pain points of traditional equipment and optimize the production process. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a batching device for mining resin anchoring agent, which solves the technical problem that existing devices in the prior art concentrate the raw material proportioning and mixing processes in the same equipment, lack independent pre-mixing and temporary storage structures, and cannot prepare the next batch of raw materials in advance during the mixing process of the current batch of materials.

[0006] According to one aspect, at least one embodiment of this disclosure provides a mixing apparatus for a mining resin anchoring agent, comprising: A support frame and a mixing box, wherein the mixing box is mounted on the support frame; A horizontal shaft and a tilting discharge assembly are provided. The horizontal shaft is rotatably connected within the support frame, and the tilting discharge assembly is disposed between the support frame and the mixing box. A weighing assembly, wherein the weighing assembly is disposed on the ingredient bin and the support; The weighing assembly includes a connecting seat, which is welded and fixed to the horizontal axis. A pair of fixed plates are provided on the side surface of the batching box. A pair of movable rods are vertically fixed between the fixed plates. The movable rods are vertically and movably fitted into the connecting seat. A weight sensor is provided on the top of the connecting seat. The upper end of the weight sensor is attached to the bottom surface of the fixed plate located at the top.

[0007] According to another aspect, in at least one embodiment of the present invention, the flipping discharge assembly includes a crossbeam, the crossbeam being horizontally fixed within the bracket, a drive motor being provided at the bottom of the crossbeam, and a worm gear being provided at the output end of the drive motor.

[0008] As a further technical solution, a transmission shaft is rotatably connected to the side surface of the bracket. A worm gear is provided at one end of the transmission shaft, which meshes with the worm. A drive gear is provided at the other end of the transmission shaft, and a driven gear is provided at one end of the horizontal shaft.

[0009] As a further technical solution, the driving gear meshes with the driven gear, and a discharge pipe is provided at the upper end of the side surface of the batching box, the discharge pipe having a bent transition structure.

[0010] As a further technical solution, an extension frame is provided at the bottom of the cross frame, and a display is provided at one end of the extension frame.

[0011] As a further technical solution, the two sides of the mixing box transition into a slope towards the back, and the opening of the mixing box is inclined.

[0012] As a further technical solution, the ingredient bin can be rotated 120° via a horizontal axis.

[0013] As a further technical solution, both ends of the bottom of the bracket are L-shaped structures, and both ends of the bottom of the bracket are provided with reinforcing ribs.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: This disclosure addresses the problems of large weighing errors and susceptibility to interference in traditional batching weighing by using a weighing assembly. The connecting seat is welded and fixed to the horizontal axis, providing a stable foundation for weighing. A fixed plate on the side surface of the batching box is vertically connected to a movable rod, which is fitted inside the connecting seat to form a bidirectional guide, limiting the batching box to vertical displacement only and preventing lateral vibration from interfering with weighing accuracy. The weight sensor on the top of the connecting seat is tightly fitted to the top fixed plate, directly bearing the weight of the raw materials to ensure accurate pressure transmission. Combined with a display on the extension frame, the batching weight is fed back in real time, facilitating precise control of the batching ratio by operators and preventing raw material waste or unstable anchoring agent performance due to imbalanced ratios.

[0015] The entire component has a strong rigid structure, making it suitable for dusty mining environments. The synergistic effect of guidance and sensing ensures the accuracy of batching and provides reliable weighing support for pre-batching, ensuring that the proportion of each batch of raw materials meets the requirements. This guarantees the key performance of the anchoring agent, such as bonding strength and solidification speed. It can complete batching while the mixing device is running, and continuous feeding saves processing time. Attached Figure Description

[0024] like Figures 1-3 As shown, it illustrates a mineral resin anchoring agent batching device according to an embodiment of the present disclosure, comprising: A support frame 1 and a mixing box 2, wherein the mixing box 2 is mounted on the support frame 1; The horizontal shaft 3 and the tilting and discharging assembly 5 are provided. The horizontal shaft 3 is horizontally rotatably connected inside the bracket 1, and the tilting and discharging assembly 5 is disposed between the bracket 1 and the batching box 2. Weighing component 4, which is disposed on the mixing box 2 and the bracket 1; The weighing assembly 4 includes a connecting seat 4-1, which is welded and fixed to the horizontal shaft 3. A pair of fixing plates 4-2 are provided on the side surface of the batching box 2. A pair of movable rods 4-3 are vertically fixed between the fixing plates 4-2. The movable rods 4-3 are vertically and movably fitted into the connecting seat 4-1. A weight sensor 4-4 is provided on the top of the connecting seat 4-1. The upper end of the weight sensor 4-4 is attached to the bottom surface of the fixing plate 4-2 located at the top.

[0025] In some examples, in order to achieve accurate weighing of resin anchoring agent raw materials and solve the problems of large errors caused by vibration interference and uneven force in traditional batching and weighing, a weighing component 4 was designed. This component includes a bracket 1 made of high-strength steel welded together to provide stable support for the overall equipment. The horizontal shaft 3 is horizontally rotatably connected to the bracket 1 through bearings, serving as both the tilting support shaft of the batching box 2 and the installation reference for the weighing component 4. The batching box 2 is indirectly connected to the horizontal shaft 3 through the weighing component 4, taking into account both the weighing function and the tilting requirement.

[0026] The connecting seat 4-1 is made of steel plate and welded to the horizontal axis 3 to ensure the rigidity of the connection and avoid deformation during weighing. A pair of fixed plates 4-2 on the side surface of the batching box 2 are rigidly connected to the box wall by bolts. The movable rod 4-3 between the fixed plates 4-2 is vertically fixed by welding. The movable rod 4-3 is vertically and movablely fitted with the sliding sleeve inside the connecting seat 4-1 to form a two-way guide structure, which restricts the batching box 2 to only slight vertical displacement and avoids lateral swaying that affects the weighing accuracy.

[0027] The weight sensor 4-4 on the top of the connecting seat 4-1 is fixed with bolts. The upper end of the sensor is tightly fitted to the bottom surface of the top fixing plate 4-2. The sensor uses a high-precision pressure sensing chip and is equipped with an external dustproof protective cover to adapt to the dusty environment of mining. After the raw materials are put into the batching box 2, the weight is transferred to the weight sensor 4-4 through the fixing plate 4-2. The movable rod 4-3 and the guide of the sliding sleeve ensure that the pressure acts perpendicularly on the sensor, reducing vibration interference and realizing accurate detection of the raw material weight. This provides data support for the anchoring agent ratio and meets the high-precision requirements of mining batching.

[0028] like Figures 1-3As shown in the figure, the present embodiment proposes that the tilting discharge assembly 5 includes a crossbeam 5-1, which is horizontally fixed inside the support 1. A drive motor 5-2 is provided at the bottom of the crossbeam 5-1, and a worm gear 5-3 is provided at the output end of the drive motor 5-2. A transmission shaft 5-4 is rotatably connected to the side surface of the support 1. A worm wheel 5-5 is provided at one end of the transmission shaft 5-4, and the worm wheel 5-5 meshes with the worm gear 5-3. A drive gear 5-6 is provided at the other end of the transmission shaft 5-4. A driven gear 5-7 is provided at one end of the crossbeam 3, and the drive gear 5-6 meshes with the driven gear 5-7. A discharge pipe 5-8 is provided at the upper end of the side surface of the batching box 2, and the discharge pipe 5-8 has a bent transition structure.

[0029] In some examples, in order to achieve stable tilting and accurate discharging of the batching box 2 and solve the problems of easy jamming and uncontrollable discharge angle of traditional tilting mechanisms leading to material spillage, a tilting and discharging component 5 was designed. This component includes a cross frame 5-1 made of channel steel welded together and horizontally fixed in the lower part of the bracket 1, providing a stable mounting carrier for the drive components. The drive motor 5-2 at the bottom of the cross frame 5-1 is rigidly fixed by a motor mount. The motor output end is fixed to the worm gear 5-3 by a key connection. The worm gear 5-3 is heat-treated by quenching to improve wear resistance and transmission accuracy.

[0030] The side surface of the bracket 1 is horizontally rotatably connected to the drive shaft 5-4 via a bearing seat. The worm gear 5-5 at one end of the drive shaft 5-4 is fixed by a key and precisely meshes with the worm 5-3 to form a reduction transmission pair. The self-locking characteristics of the worm gear 5-5 and the worm 5-3 are used to prevent the batching box 2 from accidentally overturning. The drive gear 5-6 at the other end of the drive shaft 5-4 precisely meshes with the driven gear 5-7 at one end of the horizontal shaft 3 to form a secondary transmission structure. The rigidity of the gear transmission ensures smooth power transmission.

[0031] The discharge pipes 5-8 on the upper part of the side surface of the batching box are welded to the box wall. The pipes have a bent transition structure and the bending angle is optimized to ensure that the raw materials can flow into the mixing equipment in a directional manner along the pipe when the material is turned over for discharge, thus avoiding spillage and waste.

[0032] During operation, the drive motor 5-2 starts and drives the worm gear 5-3 to rotate. Through the linkage of the worm wheel 5-5, transmission shaft 5-4, drive gear 5-6 and driven gear 5-7, the horizontal shaft 3 and the batching box 2 are driven to rotate around the shaft. The worm wheel 5-5 and worm gear 5-3 achieve speed reduction and torque increase, which is adapted to the rotation resistance when the batching box 2 is fully loaded. The gear meshing ensures that the rotation angle is precise and controllable. The bent discharge pipe 5-8 cooperates with the rotation action to achieve directional discharge. The overall structure is adapted to the heavy-duty and high-stability batching requirements of mining.

[0033] For example, such as Figure 1 As shown, an extension frame 6 is provided at the bottom of the cross frame 5-1, and a display 7 is provided at one end of the extension frame 6.

[0034] In some examples, the extension frame 6 at the bottom of the crossbeam 5-1 is welded from angle steel and fully welded to the crossbeam 5-1 to form a rigid support. One end of the extension frame 6 is bolted to the display 7. The display 7 is electrically connected to the weight sensor 4-4 to display the batching weight in real time. The screen is equipped with a dustproof and waterproof cover to adapt to the dusty and humid environment of mining. The extension frame 6 is placed away from the transmission components, does not interfere with the tipping and discharging, and is at a height suitable for the operator's reading angle, ensuring accurate and controllable batching.

[0035] For example, such as Figure 1 As shown, the two sides of the mixing box 2 slope towards the back, and the opening of the mixing box 2 is inclined.

[0036] In some examples, the sloping transitions on both sides of the mixing bin 2 are integrally welded to the bin body, with the slopes converging towards the back. The inner walls are polished to reduce material residue. The opening angle is adapted to the feeding equipment, and the sloping structure allows the raw materials to slide naturally to the bottom of the bin, avoiding accumulation dead corners. When discharging by tilting, the sloping inner wall guides the raw materials to flow quickly to the discharge pipes 5-8, improving the thoroughness of discharge and reducing material waste.

[0037] For example, such as Figure 1 As shown, the ingredient container 2 can be rotated 120° via the horizontal axis 3.

[0038] In some examples, the 120° rotation of the batching bin 2 is precisely controlled by a worm gear 5-5 and worm 5-3 in conjunction with gear transmission, while the drive shaft 5-4 is equipped with an angle sensor that provides real-time feedback on the rotation angle. When the bin rotates to 120°, the motor automatically stops, and the self-locking characteristic of the worm gear 5-5 and worm 5-3 fixes its position, combined with damping positioning to ensure stable discharge. This angle allows the discharge pipe 5-8 to be precisely aligned with the feed inlet of the mixing equipment, preventing raw material spillage and meeting the high-efficiency requirements of mining batching.

[0039] For example, such as Figure 1 As shown, both ends of the bottom of the bracket 1 are L-shaped structures, and both ends of the bottom of the bracket 1 are provided with reinforcing ribs 8.

[0040] In some examples, the L-shaped structures at both ends of the bottom of the support 1 are integrally welded to the main body of the support 1, and thick steel plates are used to enhance the load-bearing strength. Triangular reinforcing ribs 8 are welded to both ends of the bottom, and the rib plates are fully welded to the support 1 and the bottom plane to form a stable support structure. The L-shaped structure increases the grounding area, and the reinforcing ribs 8 disperse the pressure of the batching box 2 when it is fully loaded, preventing the support 1 from deforming under heavy load and ensuring the stable operation of the equipment.

[0041] In actual use: The L-shaped structure and reinforcing ribs 8 at the bottom of the support 1 securely install the equipment at the production station. The horizontal axis 3 is horizontally rotatable within the support 1, ensuring smooth rotation of the mixing box 2. Upon starting the equipment, the weight sensor 4-4 and the display 7 on the extension frame 6 are energized and linked. The sloping structure and inclined openings on both sides of the mixing box 2 facilitate the input of raw materials. The first batch of resin anchoring agent raw materials is added to the mixing box 2 according to the specified ratio. The movable rod 4-3 is vertically fitted into the connecting seat 4-1 to provide guidance. The weight is transmitted to the weight sensor 4-4 through the fixed plate 4-2, and the real-time weight data is displayed on the display 7, precisely controlling the mixing amount. After mixing, the raw materials are temporarily stored in the mixing box 2. At this time, the next batch of raw materials can be simultaneously added for weighing. The process involves re-mixing and pre-storing raw materials. When the current batch of raw materials needs to be mixed, the drive motor 5-2 of the tilting discharge assembly 5 is activated, driving the worm gear 5-3 to rotate. This worm gear meshes with the worm wheel 5-5, driving the transmission shaft 5-4 to rotate. This, in turn, drives the horizontal shaft 3 and the mixing box 2 to tilt through the drive gear 5-6 and the driven gear 5-7. The mixing box 2 tilts to a specified angle via the horizontal shaft 3, and its internal sloping structure guides the raw materials through the bent discharge pipe 5-8 into the mixing equipment. The self-locking characteristics of the worm wheel 5-5 and the worm gear 5-3 prevent accidental tilting. After the discharge is completed, the drive motor 5-2 rotates in the opposite direction, driving the mixing box 2 to reset. The next batch of pre-stored raw materials can then be directly tilted and discharged without stopping the machine, completing the continuous batching process.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
