Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment technology, and in particular to an integrated loader for mining excavation and transportation. Background Technology

[0002] In existing mining and material transfer operations, the traditional operating mode usually requires the separate use of excavators for material extraction, screening machines for aggregate separation, and transport vehicles for material transfer.

[0003] This multi-equipment, separate operation method not only leads to complex equipment flow and scheduling, greatly increasing work preparation time and equipment investment costs, but also lacks continuity between various processes. The excavated ore often needs to be transported multiple times before it can be screened, affecting the overall mining and construction efficiency. In addition, some existing loading equipment lacks an effective buffer protection mechanism. The heavy mixed ore can easily generate huge rigid impacts when poured directly onto the screening components, which can easily cause deformation of the equipment frame or damage to precision screening components, thereby reducing the service life and reliability of the equipment.

[0004] Therefore, this utility model proposes an integrated loader for mining excavation and transportation to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology, such as poor operation continuity and low efficiency due to the separation of mining excavation and screening and transportation equipment, and the lack of buffering mechanism that makes the equipment susceptible to impact damage, this utility model aims to provide a mining excavation and transportation integrated loader with improved structure, integrated excavation, screening and transportation functions and multi-level buffer protection capabilities.

[0006] This utility model provides an integrated loader for mining excavation and transportation, including a transport body, a mounting frame bolted to the area above the frame of the transport body, a conveyor belt laid flat on the support beam and roller structure of the mounting frame, and a foldable excavator bucket mounted on the front frame of the transport body via a hinge shaft. The loader also includes a separation assembly fixed to the feed end above the mounting frame. The separation assembly includes a hopper storage tank, a spring-loaded V-shaped baffle located directly below the hopper storage tank, and a subdivision compartment located directly below the spring-loaded V-shaped baffle.

[0007] The conveyor body has a vertical support frame welded to its frame. An L-shaped connecting plate is fixedly connected to the top of the support frame. A V-shaped mounting groove is welded to the horizontal end of the L-shaped connecting plate. A spring-loaded V-shaped baffle is fixed to the inner groove of the V-shaped mounting groove by bolts. The fine sorting compartment is fixed to the conveyor body frame by bolts. An inclined L-shaped screening screen is installed inside the fine sorting compartment, and a vibration motor drives the L-shaped screening screen to vibrate.

[0008] Furthermore, the transport machine body, the mounting frame, and the separation assembly are combined by bolt fastening and welding, and the upper and lower cooperation of the spring-loaded V-shaped baffle and the L-shaped screening screen forms a continuous buffer screening structure.

[0009] Preferably, in order to utilize the high elasticity of the material in conjunction with the mechanical structure to effectively absorb the impact kinetic energy when the material falls, a shock-absorbing pad is laid between the contact area between the support frame and the V-shaped mounting groove.

[0010] Preferably, in order to facilitate the rapid convergence and precise falling of the excavated mixture into the buffer area, the funnel storage tank has a conical structure that is wider at the top and narrower at the bottom, and a U-shaped positioning frame is welded to the bottom opening of the funnel storage tank, with the slot of the U-shaped positioning frame facing the spring-loaded V-shaped baffle.

[0011] Preferably, in order to provide a stable and strong excitation source for the screening process, an L-shaped suspension frame is welded and fixed to the upper internal area of ​​the subdivision compartment, the vibration motor is bolted to the horizontal beam of the L-shaped suspension frame, and the output shaft end of the vibration motor is connected to a vibration block through a coupling.

[0012] Preferably, in order to ensure the vibration amplitude of the screen while blocking the transmission of vibration to the outer wall of the fine separation chamber, the upper edge of the L-shaped screen is connected to the discharge port of the spring-loaded V-shaped baffle by a snap fastener, and a spring damper is connected between the side frame of the L-shaped screen and the inner wall hanging ring of the fine separation chamber.

[0013] Preferably, in order to achieve automated grading and directional discharge of excavated materials, the interior of the subdivision bin is divided into upper and lower areas by steel plates. A sand discharge outlet is opened on one side of the bottom of the lower area of ​​the subdivision bin, and a stone discharge outlet is connected to the bottom of the other side. The lower edge of the L-shaped screening mesh corresponds to the soil disposal area outside the subdivision bin and the stone discharge outlet, respectively.

[0014] Preferably, in order to achieve centralized management and control of the equipment, a control device is integrated into the operating cabin area of ​​the transport aircraft body, and the control device is electrically connected to the drive mechanism of the vibration motor and the foldable excavator bucket.

[0015] Preferably, in order to avoid interference with the movement of the mechanism and to prevent foreign objects from entering the device when idle, a protective sealing door is installed on the frame of the conveyor body near the feeding side via a hinge. The protective sealing door is located outside the storage path of the foldable excavator bucket.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of poor continuity and low efficiency in existing mining operations, which is usually carried out independently by different equipment for excavation, screening and transportation. It achieves the effect of integrated continuous operation of excavation, material handling, vibration screening and separation and material transfer, thereby improving the construction efficiency of mining and reducing equipment turnover costs.

[0017] 2. This utility model solves the problem that heavy mixed mineral materials falling directly onto the screening components can easily cause frame deformation or damage to precision parts by setting a V-shaped baffle with a spring at the feed end and using shock-absorbing pads laid between the support frame and the baffle mounting groove to form a multi-level buffer structure. This achieves the effect of effectively absorbing the impact energy of falling materials, protecting the screening mechanism below, and extending the service life of the overall device.

[0018] 3. This utility model solves the problem of the difficulty in quickly and automatically separating and directionally diverting mixed mineral materials from sand and stones by using a vibrating motor to drive an inclined L-shaped screening screen and combining it with an internally physically layered subdivided compartment structure. It achieves the effect of using high-frequency vibration to accurately classify sand and stones and discharge them to the conveyor belt through different outlets, thus realizing the automated classification and processing of materials.

[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. 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.

[0022] Please refer to Figures 1 to 4 This utility model provides an integrated loader for mining excavation and transportation, which aims to solve the technical problems of low operating efficiency caused by the separation of excavation and screening transportation equipment in the prior art, and the easy damage to the equipment caused by direct impact of ore on the screening components.

[0023] like Figure 1 As shown, the mining excavator and transport integrated loader mainly consists of a transporter body 1, a mounting frame 202, a conveyor belt 203, and a foldable excavator bucket 3. The transporter body 1 serves as the mobile and load-bearing foundation for the entire device, and its bottom is equipped with a set of travel wheels. The mounting frame 202 is fixedly connected to the upper area of ​​the frame of the transporter body 1 by high-strength bolts, providing a support platform for subsequent material transfer. The conveyor belt 203 is laid flat on the support beam and roller structure inside the mounting frame 202. The conveyor belt 203 runs through the machine body to stably transport the separated material to the rear. The foldable excavator bucket 3 is rotatably connected to the front frame of the transporter body 1 through a hinge shaft. The foldable excavator bucket 3 can rotate around the hinge shaft under the drive of a hydraulic cylinder or an electric push rod. When working, it is unfolded to a horizontal digging angle, and when not working, it is folded upwards to reduce the size of the equipment.

[0024] A separation component 2 is fixedly installed at the upper feed end of the mounting frame 202. The separation component 2 mainly includes a funnel storage tank 201, a support and buffer mechanism, and a V-shaped baffle 208 with a spring. The funnel storage tank 201 is fixed at the top of the mounting frame 202 by a bracket. The funnel storage tank 201 is designed as an inverted cone structure that is wider at the top and narrower at the bottom to facilitate material gathering. A U-shaped positioning frame 205 is welded at the bottom opening. The slot of the U-shaped positioning frame 205 faces vertically downward and is aligned with the buffer area below, which is used to initially gather and guide the excavated mixed mineral material.

[0025] To effectively absorb the impact force generated by the falling ore, a support frame 204 is vertically fixed to the frame of the conveyor body 1 by welding. The support frame 204 is located directly below the funnel storage tank 201. An L-shaped connecting plate 206 is fixed to the top plane of the support frame 204 by bolts. A V-shaped mounting groove 207 is fixed to the horizontal extension end of the L-shaped connecting plate 206 by welding. A spring-loaded V-shaped baffle 208 is fixed to the inner groove of the V-shaped mounting groove 207 by bolts. The spring-loaded V-shaped baffle 208 integrates a spring return structure. At the same time, a shock-absorbing pad 216 is laid between the rigid contact surfaces of the support frame 204 and the V-shaped mounting groove 207. The shock-absorbing pad 216 is made of wear-resistant and highly resilient rubber. When the material falls from the U-shaped positioning frame 205 onto the surface of the spring-loaded V-shaped baffle 208, the spring structure of the V-shaped baffle itself, together with the shock-absorbing pad 216 at the bottom, undergoes elastic deformation, thereby greatly reducing the rigid impact of the material on the frame.

[0026] A fine sorting bin 209 is located directly below the spring-loaded V-shaped baffle 208. The fine sorting bin 209 is fastened to the frame of the conveyor body 1 by bolts. The internal space of the fine sorting bin 209 is physically divided into two independent upper and lower areas by steel plates. An L-shaped screening screen 214 is installed at an angle in the upper area of ​​the fine sorting bin 209. The upper edge of the L-shaped screening screen 214 is movably connected to the discharge port of the spring-loaded V-shaped baffle 208 by a snap fastener. In order to prevent the vibration during screening from being transmitted to the bin body, a spring damper 215 is connected between the side frame of the L-shaped screening screen 214 and the inner wall hanging ring of the fine sorting bin 209. The L-shaped screening screen 214 is in a suspended floating state.

[0027] To provide screening power, an L-shaped suspension frame 211 is welded and fixed to the upper internal area of ​​the fine separation bin 209. The vibration motor 212 is firmly installed on the horizontal beam of the L-shaped suspension frame 211 by bolts. The output shaft end of the vibration motor 212 is coaxially connected to the vibrating block 213 through a coupling. When the vibration motor 212 starts, it drives the vibrating block 213 to rotate and generate centrifugal excitation force, which causes the L-shaped screening screen 214 to generate high-frequency vibration. The mixed mineral material jumps and layers on the screen surface. Fine sand passes through the mesh and falls into the lower layer of the fine separation bin 209, and is discharged from the sand discharge port 210 opened on one side of the lower layer. Large stones that cannot pass through the mesh slide down the inclined screen surface to the stone discharge port 217 connected to the bottom of the other side of the fine separation bin 209 and are discharged. Medium-sized soil clods slide from the lower edge of the L-shaped screening screen 214 to the specially designated soil disposal area outside the fine separation bin 209.

[0028] In addition, a control device 4 is integrated in the operating cabin of the transport machine body 1. The control device 4 is connected to the vibration motor 212 and the excavator bucket drive mechanism through electrical lines to realize one-button start / stop and action control. A protective sealing door 5 is installed on the frame of the transport machine body 1 near the feeding side through a hinge. The protective sealing door 5 is located outside the storage path of the foldable excavator bucket 3 and can be manually closed to seal the feeding port when the equipment is idle.

[0029] The working principle of this utility model of integrated mining excavation and transportation loader is as follows: At the start of the operation, the operator starts the equipment through the control device 4, driving the foldable excavator bucket 3 to unfold to a horizontal position for excavation. The excavated mixed ore is poured into the funnel storage tank 201 at the top. Under the action of gravity, the mixed ore is gathered and guided by the U-shaped positioning frame 205 at the bottom of the funnel storage tank 201 and falls directly onto the surface of the spring-loaded V-shaped baffle 208. At this time, the spring-loaded V-shaped baffle 208 uses its own spring structure and works with the shock-absorbing pad 216 at the bottom to generate elastic buffer deformation, effectively absorbing the huge impact kinetic energy of the falling ore and preventing rigid impact from damaging the frame structure.

[0030] After being buffered, the material falls onto the L-shaped screening screen 214 in the fine separation bin 209. The control device 4 starts the vibration motor 212, which drives the vibrating block 213 to rotate at high speed to generate excitation force, causing the L-shaped screening screen 214 to generate continuous high-frequency vibration. The spring damper 215 ensures the vibration amplitude of the screen while blocking the transmission of vibration to the fine separation bin 209. During the vibration screening process, smaller sand particles pass through the mesh and fall into the lower layer and are discharged through the sand discharge port 210. Large stones slide down the inclined screen surface to the stone discharge port 217 and are discharged. The separated material finally flows into the conveyor belt 203 below. The conveyor belt 203 continues to operate under the support of the mounting frame 202, transporting the sorted material to the designated position. After the operation is completed, the foldable excavator bucket 3 is folded and stored and the protective sealing door 5 is closed.

[0031] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
