Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to a screw-type wet concrete spraying machine for metal mines. Background Technology

[0002] Shotcrete is widely used in roadway anchoring and spraying support. With increasing environmental awareness and higher quality requirements for shotcrete, more and more companies are adopting wet shotcrete. Currently, metal mines mainly use wet shotcrete trolleys for wet shotcrete. While these trolleys offer advantages such as high construction efficiency and stable performance for large-area concentrated shotcreting operations, they also have disadvantages in confined underground spaces, especially when multiple sections need to be shotcreted simultaneously. These disadvantages include inconvenience in movement, difficulty in organizing production, cumbersome cleaning and maintenance, and high cost. To address these issues, screw-type wet shotcrete machines have begun to be used in small-area shotcrete applications in metal mines in recent years.

[0003] Currently, screw-type wet concrete spraying machines on the market have advantages such as compact structure, convenient relocation, and simple operation. However, they also have drawbacks such as inconvenience in maintenance and replacement of parts, and the inability to directly wash the vibrator, which makes it easy to be damaged. These factors restrict the promotion and application of screw-type wet concrete spraying machines. Utility Model Content

[0004] This utility model provides a screw-type wet concrete spraying machine for metal mines, which solves the problems of inconvenient maintenance and parts replacement, and the inability to directly wash the vibrator, which is easily damaged in existing screw-type wet concrete spraying machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screw-type wet concrete spraying machine for metal mines includes a frame, on which an electric screw pumping system is mounted. A screw conveyor shaft is detachably connected within the electric screw pumping system, and a power unit is rotatably connected to the screw conveyor shaft, with the power unit located on one side of the frame. An accelerator pumping system is fixedly mounted on the other side of the frame. A control box is located on the side of the accelerator pumping system. Both the electric screw pumping system and the accelerator pumping system contain motors, and both motors are connected to the control box. A hopper is rotatably mounted on the top of the electric screw pumping system, and a pneumatic vibrating screen is fixedly mounted inside the hopper. A pneumatic vibrator is mounted on the pneumatic vibrating screen.

[0007] Furthermore, a bearing chamber fixing frame is fixedly connected to the bottom of the hopper, and a screw conveyor shaft is rotatably installed inside the bearing chamber fixing frame. The bearing chamber fixing frame is fixedly connected to the power unit.

[0008] Furthermore, the top of the electric screw pumping system is rotatably equipped with a hinge shaft, and the hopper and the hinge shaft are rotatably connected.

[0009] Furthermore, the power unit is detachably connected to the first protective cover, and the electric screw pumping system is detachably equipped with a second protective cover.

[0010] Furthermore, the electric screw pumping system has a detachable through shaft at the top.

[0011] This utility model has the following beneficial effects:

[0012] The device includes an electric screw pumping system with a detachable screw conveyor shaft, bearing housing frame, and power unit. The power unit and screw conveyor shaft assembly can be pulled out of the electric screw pumping system as a whole. The hopper is equipped with a hinge shaft and a through shaft, which is a hinged quick-release structure, allowing the hopper to be quickly rotated, realizing the quick disassembly, maintenance, and parts replacement of the equipment.

[0013] The pneumatic vibrating screen inside the hopper is powered by a pneumatic vibrator, requiring no electrical control. It can be cleaned with water and requires no protection, improving the cleaning efficiency of the equipment. The first protective cover protects the motor in the accelerator pumping system, and the second protective cover protects the motor in the power unit. The second mudguard is tilted to the outside of the frame, allowing water to flow out of the frame or fall into the hopper during cleaning, preventing water accumulation on the frame and avoiding damage to other devices. Therefore, the protective cover and mudguard can be cleaned directly, improving the efficiency and convenience of maintenance and parts replacement.

[0014] The start and stop of the two motors in the electric screw pumping system and the accelerator pumping system are controlled by a centralized control box, which is equipped with a phase sequence protector to ensure that the motors do not run in reverse, thus achieving safe operation of the device.

[0015] The power unit of the electric screw pumping system and the conveying system of the accelerator pumping system are placed as close as possible to the lower side of the upper edge of the hopper, and the tank truck is placed as close as possible to the equipment when discharging material, so as to achieve feeding from three directions.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-5 As shown, a screw-type wet concrete spraying machine for metal mines includes a frame 1, an electric screw pumping system 101 mounted on the frame 1, a screw conveyor shaft 202 detachably connected inside the electric screw pumping system 101, a power unit 201 rotatably connected to the screw conveyor shaft 202, and the power unit 201 located on one side of the frame 1. A quick-setting agent pumping system 102 is fixedly mounted on the other side of the frame 1, and a control box 2 is located on the side of the quick-setting agent pumping system 102. Both the electric screw pumping system 101 and the quick-setting agent pumping system 102 are equipped with motors, and both motors are connected to the control box 2. A hopper 11 is rotatably mounted on the top of the electric screw pumping system 101, and a pneumatic vibrating screen 103 is fixedly mounted inside the hopper 11. A pneumatic vibrator 9 is mounted on the pneumatic vibrating screen 103.

[0025] The bottom of the hopper 11 is fixedly connected to a bearing chamber fixing frame 7, and a screw conveyor shaft 202 is rotatably installed inside the bearing chamber fixing frame 7. The bearing chamber fixing frame 7 is fixedly connected to the power unit 201.

[0026] The electric screw pumping system 101 has a hinge shaft 10 rotatably mounted on its top, and the hopper 11 is rotatably connected to the hinge shaft 10.

[0027] The power unit 201 is detachably connected to the first protective cover 3, and the electric screw pumping system 101 is detachably equipped with a second protective cover 4.

[0028] The electric screw pumping system 101 has a detachable through shaft 8 at the top.

[0029] In practical use, when the electric screw pumping system 101 malfunctions and requires maintenance, the power unit 201, bearing housing fixing frame 7, and screw conveyor shaft 202 can be directly disassembled and removed for repair or replacement. When the hopper 11 malfunctions, the opening of the hopper 11 can be tilted to the side by rotating the hinge shaft 10, which facilitates the repair and replacement of the internal parts of the hopper 11.

[0030] When the device needs to be cleaned, the first protective cover 3 protects the motor in the accelerator pumping system 102, the second protective cover 4 protects the motor in the power unit 201, and the second mudguard 6 is tilted to the outside of the frame 1. During cleaning, the water can be diverted to the outside of the frame 1 or fall into the hopper 11, preventing water accumulation on the frame 1 and avoiding damage to other devices. Furthermore, the pneumatic vibrating screen 103 is powered by the pneumatic vibrator 9, so it can be directly cleaned with water without further protective work, which improves the convenience and safety of the cleaning work.
