Description

Technical Field

[0001] This utility model relates to the field of concrete spraying machine technology, specifically to a dual-power wet concrete spraying machine. Background Technology

[0002] A shotcrete machine (or concrete sprayer) is a machine that uses compressed air to continuously transport concrete along a pipeline and spray it onto the construction surface. It is widely used in the lining construction of underground engineering, shafts, tunnels, culverts, etc. Wet shotcrete machines use pneumatic or launching cylinders to transport the concrete mixture through nozzles. Before transportation, various materials need to be mixed. They can directly spray finished concrete, or some have a built-in mixing hopper where various materials are mixed before being transported by the launching cylinder.

[0003] Existing common wet concrete spraying machines connect a motor directly to an oil pump. The oil pump outputs oil through a multi-way valve to drive the motor. One path drives the track, while the remaining oil drives the feeder motor, main auger motor, etc., to complete all the movements. When the motor drives the track, the speed is slow, and long-distance travel requires connecting cables to different locations in the tunnel, making operation cumbersome, inefficient, and unable to achieve rapid site relocation. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a dual-power wet concrete spraying machine.

[0005] This utility model is achieved through the following technical solution: a dual-power wet concrete spraying machine is provided, including a tracked chassis, a main feeding auger, and a launching cylinder, as well as a power motor and a diesel engine. The output shaft of the diesel engine is equipped with an engine oil pump, which drives the walking motor of the tracked chassis to rotate; the output shaft of the power motor is equipped with an electric motor oil pump, which drives the main feeding auger motor and the launching cylinder to rotate.

[0006] As an optimization, the main feeding screw is inclined and the lower end is fixedly connected to a first hopper, a second hopper, and a third hopper. The outlets of the first hopper, the second hopper, and the third hopper are all located above the inlet of the main feeding screw.

[0007] As an optimization, the first, second, and third hoppers are respectively shaft-connected with a first spiral conveyor shaft, a second spiral conveyor shaft, and a third spiral conveyor shaft. The hopper motor drives the first, second, and third spiral conveyor shafts to rotate through a transmission box, and the motor oil pump drives the hopper motor to rotate.

[0008] As an optimization, a mixing hopper connected to the inlet of the launching cylinder is provided below the outlet of the main feeding spiral.

[0009] As an optimization, the lower end of the main feeding auger is hinged to the tracked chassis, and a telescopic support rod is connected between the main feeding auger and the tracked chassis.

[0010] As an optimization, the engine oil pump is a gear pump, and the motor oil pump is a plunger pump.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a dual-power wet concrete spraying machine with a simple structure and easy operation, which can meet the requirements of rapid site relocation, quick power switching, and immediate operation in non-coal mines. Furthermore, since the diesel engine is only used to power the track movement, rather than all actions, a smaller diesel engine can be selected. A smaller diesel engine is smaller and lighter, offering a greater size advantage in underground equipment. Attached Figure Description

Detailed Implementation

[0017] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0018] like Figures 1-3 As shown, this utility model discloses a dual-power wet concrete spraying machine, which includes a tracked chassis 1, a main feeding auger 2, and a launching cylinder 4. The tracked chassis 1 is located at the bottom of the spraying machine and is the supporting component for the movement of the entire spraying machine. The walking motor drives the tracks on both sides of the tracked chassis 1 through a reduction motor to achieve movement.

[0019] The main feeding spiral 2 is inclined, with an inlet at the top of the lower end and an outlet at the bottom of the upper end. The internal spiral conveying paddle is driven to rotate by the main feeding spiral motor 9, thereby conveying the internal material from the inlet to the outlet.

[0020] The lower end of the main feeding auger 2 is hinged to the tracked chassis 1, and a telescopic support rod 5 connects the main feeding auger 2 and the tracked chassis 1. The telescopic support rod includes an upper rod body, an adjusting tube, and a lower rod body. The upper and lower rod bodies are round rods, and the adjusting tube is a round tube. The upper end of the upper rod body is hinged to the main feeding auger, and the lower end of the upper rod body is threaded to the upper end of the adjusting tube. The upper end of the lower rod body is threaded to the lower end of the adjusting tube, and the lower end of the lower rod body is hinged to the chassis. The threads at the upper and lower ends of the adjusting tube rotate in opposite directions. Therefore, the length of the entire telescopic support rod can be adjusted by rotating the adjusting tube. To facilitate manual rotation of the adjusting tube, a handle is fixed to the adjusting tube, and two handles are provided, located on both sides of the adjusting tube. By holding the two handles with both hands, it is easy to rotate the adjusting tube.

[0021] The lower end of the main feeding screw 2 is fixedly connected to a first hopper 11, a second hopper 12, and a third hopper 13. The outlets of the first hopper 11, the second hopper 12, and the third hopper 13 are all located above the inlet of the main feeding screw 2. Figure 3 As shown, the second hopper 12 and the third hopper 13 are arranged side by side, while the first hopper 11 and the second hopper 12 are arranged front to back. The first hopper 11, the second hopper 12, and the third hopper 13 are used to add different materials.

[0022] The first hopper 11, the second hopper 12, and the third hopper 13 are respectively connected to a first screw conveyor shaft 14, a second screw conveyor shaft 15, and a third screw conveyor shaft 16. By rotating the first screw conveyor shaft 14, the second screw conveyor shaft 15, and the third screw conveyor shaft 16, the materials in the first hopper 11, the second hopper 12, and the third hopper 13 are respectively conveyed to their respective outlets.

[0023] In order to achieve the rotation of the first spiral conveying shaft 14, the second spiral conveying shaft 15 and the third spiral conveying shaft 16, this application also includes a hopper motor 10. The hopper motor 10 is a hydraulic motor. The hopper motor 10 drives the first spiral conveying shaft 14, the second spiral conveying shaft 15 and the third spiral conveying shaft 16 to rotate through the transmission box 8. The motor oil pump drives the hopper motor 10 to rotate.

[0024] The transmission box 8 includes a box body and an input shaft and an output shaft rotatably connected side-by-side on the transmission box. One end of the input shaft is connected to the hopper motor, and the other end is connected to the third spiral conveyor shaft. An input shaft gear is fixedly connected to the input shaft, and an output shaft gear is fixedly connected to the output shaft. The input shaft gear is connected to the output shaft gear through an intermediate gear. One end of the output shaft is connected to the first spiral conveyor shaft, and the other end is connected to the second spiral conveyor shaft.

[0025] Below the outlet of the main feeding spiral 2, there is a mixing hopper 3 connected to the inlet of the launching cylinder 4. The main feeding spiral 2 mixes and conveys the material into the mixing hopper 3, and then conveys it outward through the launching cylinder 4.

[0026] It also includes a power motor and a diesel engine 6. The output shaft of the diesel engine 6 is equipped with an engine oil pump 7, which is a gear pump with a large flow rate. The engine oil pump 7 drives the walking motor of the tracked chassis 1 to rotate, thereby achieving rapid site transfer.

[0027] An oil pump is mounted on the output shaft of the power motor. The oil pump is a plunger pump with high output pressure. The oil pump drives the main feeding screw motor 9 of the main feeding screw 2 and the launching motor of the launching cylinder 4 to rotate.

[0028] The oil output from the gear pump and the oil output from the plunger pump driven by the motor merge into the multi-way valve, which controls the switching. However, there are check valves between the gear pump and the multi-way valve, as well as between the plunger pump and the multi-way valve.

[0029] The tracked chassis 1 is also equipped with a hydraulic oil tank, a diesel tank, and a battery. The hydraulic oil tank is used to supply hydraulic oil, the diesel tank is used to supply diesel fuel to the diesel engine 6, and the battery is used to supply power to the power motor.

[0030] How to use this utility model:

[0031] Materials enter the main feeding screw 2 from the first hopper 11, the second hopper 12 and the third hopper 13, and are conveyed upward by the main feeding screw 2. The main feeding screw 2 mixes and conveys the materials to the mixing hopper 3, and then conveys them outward through the launching cylinder 4.

[0032] The output end of the diesel engine 6 is connected to the gear pump. When the user needs to move between sites, the power motor does not work and does not supply oil to the main oil circuit. The diesel engine 6 works, and the gear pump supplies oil to the main oil circuit. Through the operation of the multi-way valve, the travel motor on the tracked chassis 1 is driven, which drives the tracked chassis 1 to move.

[0033] When shotcreting is required, the diesel engine 6 is not working, but the power motor is working, driving the plunger pump to supply oil to the main oil circuit, which in turn drives the other oil circuits except the tracks to work and carry out shotcreting.

[0034] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.
