Description

Technical Field

[0001] This utility model relates to the field of material feeding equipment technology, and in particular to a material feeding device for mine sprayed slurry material with vibrating wall of a storage belt conveyor. Background Technology

[0002] With the continuous growth of mining demand, mining has gradually shifted from open-pit to underground mining. Underground mining systems mainly consist of four parts: vertical shafts, ramps, inclined shafts, and horizontal tunnels. Vertical shaft excavation and construction generally uses cast-in-place concrete support, while ramps, inclined shafts, and horizontal tunnels use shotcrete or anchor-mesh shotcrete support when geological conditions are favorable. Currently, domestic mines commonly use a combined development method of vertical shafts and horizontal tunnels. However, after the vertical shaft construction is completed and the development transitions to the horizontal tunnels, how to smoothly lower the support materials has become a construction challenge. Traditionally, the feeding method for shotcrete support materials usually involves a combination of inclined chute and feed pipe. However, there are many problems in actual operation: First, a loader is needed to shovel the mixed shotcrete into the inclined chute, and the material is allowed to slide down the chute to the feed pipe by gravity. However, because the shotcrete itself is sticky and has a strong adhesion to the inner wall of the inclined chute, the material cannot flow completely into the feed pipe and enter the well. As a result, after each feeding, the remaining material attached to the inclined chute must be cleaned manually with a shovel before the next shovel can be fed.

[0003] Secondly, traditional inclined chutes are often placed close to the shaft opening due to construction layout limitations. When workers clean the inclined chutes near the shaft opening, there is a risk of falling from height. In addition, the loader bucket has a large capacity while the inclined chute volume is small. When the loader unloads material, it needs to park next to the inclined chute for a long time, which not only occupies the loader's working time and makes it impossible to carry out other work at the same time, but also increases labor costs due to the repeated unloading and cleaning operations.

[0004] More importantly, this feeding method is affected by human operation and material characteristics, resulting in uneven feeding speed and easy blockage of the feeding pipe. This not only reduces construction efficiency but also easily extends working hours due to frequent blockage handling. The whole process is labor-intensive and time-consuming, and is accompanied by safety hazards and cost waste. Utility Model Content

[0007] Optionally, the lifting mechanism includes a cylinder fixedly connected to the base frame, the inside of the conveying mechanism is provided with a support frame, and support clamps are fixedly connected to the outer walls on both sides of the support frame.

[0010] Optionally, both the first bracket and the second bracket have a baffle fixedly connected to the end away from the support base to lock the conveying mechanism.

[0014] This invention utilizes a support base and conveying mechanism to store shotcrete material in a storage bin that can be moved after being unloaded by a forklift, reducing space requirements.

A cylinder piston rod extends and retracts to adjust the height of the conveying mechanism at the bottom of the storage bin, thereby controlling the amount of material discharged from the bottom. Ultimately, this achieves efficient and uniform material distribution, saving manpower and resources, and improving safety. Attached Figure Description

[0025] Example

[0026] like Figures 1 to 3 As shown, this utility model proposes a vibrating conveyor belt wall device for discharging sprayed slurry in mines. It includes a wellhead 1 and a storage bin 3. The storage bin 3 is made of steel plates and angle steel through welding, and is shaped like a trumpet with a wider top and a narrower bottom. A support base 2 is provided at the bottom of the storage bin 3. The support base 2 is made of square steel and angle steel through welding to support the storage bin 3, ensuring a gap (at least 3cm) between the bottom opening of the storage bin 3 and the conveying mechanism 5 for material flow. This guarantees that the sprayed slurry can flow out smoothly when the conveyor belt is rotating, and that the sprayed slurry is held in place by the conveying mechanism 5 when the belt is not rotating. The conveying mechanism 5 is located directly below the bottom of the storage bin 3 on the support base 2. During operation, the conveying mechanism 5 transports the sprayed slurry to the discharge bin. The conveying mechanism 5 typically refers to a system that uses an electric motor as a power source to drive a conveyor belt for material transport. The conveying mechanism 5 typically consists of the following main components: a drive motor 61 (providing power to drive the conveying device). Transmission device (transmits power via gears, belts, chains, or rollers, and adjusts speed and torque). Conveying medium (such as conveyor belts, chains, or rollers, used for material conveying). Support frame 10 (supports the system and maintains tension and stability). Guiding device (ensures material moves along a designated path). Control system (adjusts speed, monitors system operation status, and ensures efficient operation). A vibrating motor 4 is also fixedly connected to the side wall of the storage silo 3. The vibrating motor 4 is a power component installed on the side wall of the storage silo 3, mainly using high-frequency vibration to eliminate the adhesion of the sprayed material to the silo wall, ensuring smooth material discharge; a base frame 9 is fixedly connected to the bottom of the support base 2.

[0027] Among them, such as Figures 2 to 3 As shown, the upper surface of the middle part of the base frame 9 is provided with a lifting mechanism that moves the conveying mechanism 5 up and down. The lifting mechanism includes a cylinder 91 fixedly connected to the base frame 9. The cylinder 91 is fixed to the base frame, and the piston rod is connected to the support clamp block, pushing the support frame to drive the conveying mechanism up and down. The conveying mechanism 5 is provided with a support frame 10 inside. The support frame 10 is located inside the conveying mechanism, connecting the first and second brackets, and supporting the conveying mechanism. Support clamp blocks 11 are fixedly connected to the outer walls on both sides of the support frame 10, and the piston rod of the cylinder 91 is fixedly connected to the lower surface of the middle part of the support clamp block 11.

[0028] In addition, such as Figures 1 to 2 As shown, a first bracket 6 is fixedly connected to one end of the support frame 10. A drive motor 61 for driving the conveying mechanism 5 is fixedly connected to one of the first brackets 6. The drive motor 61 is the power component that drives the conveying mechanism 5. It is fixedly connected to the first bracket and drives the conveying mechanism 5 to operate by outputting power, thereby conveying the sprayed slurry falling from the bottom of the storage bin 3 into the discharge bin 12 and flowing into the discharge pipe 111, realizing the discharge of the sprayed slurry. A pair of second brackets 7 are fixedly connected to the other end of the support frame 10. Both the first bracket 6 and the second bracket 7 are fixedly connected to the support base 2. A baffle 62 for locking the conveying mechanism 5 is fixedly connected to the end of the first bracket 6 and the second bracket 7 away from the support base 2. The baffle 62 is fixed to the end of the first bracket 6 and the second bracket 7 away from the support base 2, locking the conveying mechanism 5 to make its operation smooth.

[0029] It is worth noting that, such as Figures 1 to 2 As shown, sliding sleeves 8 are fixedly connected to the ends of the first bracket 6 and the second bracket 7 away from the support frame 10. The sliding sleeves 8 are fixed to the ends of the first bracket 6 and the second bracket 7 away from the support frame 10 and are slidably engaged with the support base 2 to ensure smooth movement of the conveying mechanism 5. The sliding sleeves 8 are all slidably engaged with the support base 2. A buffer spring 81 is movably fitted onto the bottom end of each support base 2. The buffer spring 81 is fitted onto the bottom end of the support base 2, with one end fixed to the base frame 9 and the other end fixed to the sliding sleeve 8, providing a buffering effect. One end of the buffer spring 81 is fixedly connected to the base frame 9, and the other end of the buffer spring 81 is fixedly connected to the corresponding sliding sleeve 8.

[0030] Furthermore, such as Figure 1 As shown, a discharge pipe 111 is fixedly connected to the inner wall of the wellhead 1. The discharge pipe 111 connects the wellhead 1 to the underground and is used to transport the shotcrete material to the designated location. A discharge bin 12 is fixedly connected to the top of the discharge pipe 111, located directly below the end of the support frame 10. The discharge bin 12 is located at the top of the discharge pipe 111 and receives the shotcrete material transported by the conveying mechanism 5, serving as a transfer device.

[0031] In this embodiment, when using the vibrating conveyor belt conveyor for mine shotcrete discharge, the device is first fixed near the wellhead 1 via the support base 2. A loader then pours the mixed shotcrete into the storage silo 3. The storage silo 3 is funnel-shaped to facilitate material storage and descent. The drive motor 61 is started, driving the conveyor mechanism 5. The shotcrete falls from the bottom of the storage silo 3, is conveyed by the conveyor mechanism 5 to the discharge hopper 12, and flows down the discharge pipe 111 to complete the discharge.

[0032] When sprayed material adheres to the inner wall of the storage silo 3, the vibration motor 4 is turned on to drive the storage silo 3 to vibrate, causing the adhered material to slide off and ensuring smooth material discharge. If it is necessary to adjust the height of the conveying mechanism 5 to increase or decrease the amount of material flowing out from the bottom of the storage silo 3, simply start the cylinder 91, whose piston rod pushes the support frame 10, causing the conveying mechanism 5 to move up and down to adapt to different material discharge requirements.

[0033] During this process, the first support 6 and the second support 7 fix the conveying mechanism 5, the sliding sleeve 8 ensures its smooth movement, and the baffle 62 ensures the smooth operation of the conveying mechanism 5. All components cooperate with each other to achieve efficient and uniform delivery of the sprayed grout, reduce the time spent on manual cleaning and loader operation, and improve construction safety and efficiency.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
