Description

Technical Field

[0001] This utility model belongs to the technical field of filling and spraying devices, specifically a multi-directional filling and spraying device for mine tunnels. Background Technology

[0002] Mine filling jetting devices are key equipment used for filling operations in mining and underground engineering. Their main function is to deliver filling materials (such as tailings, concrete, etc.) into the mine shaft using high-pressure jetting to reinforce the mine walls, prevent collapses, and improve resource recovery rates. During operation, a high-pressure pump mixes the filling material with water or other additives to form a slurry, which is then transported to the nozzle via a pipeline. Under high pressure, the nozzle generates a high-speed jet, spraying the slurry onto the mine walls or designated areas. An existing patent (publication number: CN218535127U) describes a mortar jetting device with a material-throwing mechanism installed outside the feeding hopper. The feeding mechanism prevents material from adhering to the inner wall of the feeding hopper and causing blockage of the feeding port, thus affecting normal material feeding. The spiral blades agitate the mortar deposited inside the discharge pipe, preventing the material from easily settling inside the discharge pipe and solidifying, which would prevent the mortar from being discharged normally and affect the normal operation of the device. The use of shock absorbers and buffer springs prevents the device from shaking and generating noise, thus affecting the work efficiency of the operators. However, the multi-directional adjustment of this spraying device is very inconvenient. The operator needs to push the entire device and adjust it by rolling the casters, which is very troublesome to use and its effect is not good. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a multi-directional filling and spraying device for mines, which effectively solves the problem that the existing spraying device is very inconvenient to adjust in multiple directions, requiring the operator to push the whole device and adjust it by rolling the universal wheels, which is very troublesome to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional filling injection device for mine tunnels, comprising an injection device body, universal wheels rotatably mounted at the four corners of the bottom of the injection device body, a handle fixedly mounted on one side of the injection device body, a feed valve fixedly mounted on one side of the top of the injection device body, a discharge pipe fixedly mounted in the middle of the top of the injection device body, a rotating joint rotatably mounted on the top of the discharge pipe, a first steel pipe fixedly mounted on the top of the rotating joint, a steel wire pipe fixedly mounted on the top of the first steel pipe, a second steel pipe fixedly mounted on the top of the steel wire pipe, an injection head fixedly mounted at one end of the second steel pipe, and a multi-directional adjustment component provided between the surfaces of the discharge pipe, the first steel pipe, and the second steel pipe.

[0005] Preferably, the multi-directional adjustment assembly includes a connecting frame and a bushing. The connecting frame is fixedly installed on the upper part of the surface of the discharge pipe, and the bushing is rotatably installed on the lower part of the surface of the discharge pipe. A support frame is fixedly installed on the surface of the bushing. An installation strip is fixedly installed at one end of the support frame. A fixing frame is fixedly installed on the top of the installation strip. A second motor is fixedly installed on the top of the fixing frame. A first motor is fixedly installed at the inner bottom of the connecting frame. A first gear is fixedly installed at the output end of the first motor. A second gear is meshed with one side of the first gear. The second gear is fixedly installed on the surface of the first steel pipe.

[0006] Preferably, an adjustment frame is rotatably mounted on the bottom of the mounting strip. The interior of the adjustment frame is fixedly connected to the second steel pipe via a fixing head. The output end of the second motor extends to the lower part of the fixing frame and is fixedly mounted with a threaded rod. A positioning strip is rotatably mounted on the bottom of the threaded rod, and one end of the positioning strip is fixedly connected to the mounting strip.

[0007] Preferably, the threaded rod is threadedly connected to a threaded sleeve, a connector is fixedly installed on one side of the threaded sleeve, a sliding sleeve is fixedly installed on one end of the connector, a sliding rod is inserted into the sliding sleeve, and the two ends of the sliding rod are fixedly connected to the fixing frame and the positioning strip, respectively. A transmission rod is rotatably installed on the other side of the threaded sleeve, and the bottom end of the transmission rod is rotatably connected to the upper part of the adjusting frame.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator pushes the spraying device body by the handle to drive the four universal wheels to roll, thereby moving the device to the work site. Then, the operator starts the spraying device body to spray the material through the discharge pipe, rotating joint, first steel pipe, steel wire pipe, second steel pipe and spray head. At the same time as spraying, the operator starts the second motor on the connecting frame to drive the first gear to rotate along the connecting frame. When the first gear rotates, it drives the first steel pipe to rotate along the rotating joint through the second gear. When the first steel pipe rotates, it drives the spray head to adjust the spraying direction through the steel wire pipe and the second steel pipe. When the second steel pipe rotates, it drives the bushing to rotate along the surface of the discharge pipe through the adjusting frame, mounting strip and support frame.

[0009] The operator starts the second motor on the fixed frame, which drives the threaded rod to rotate along the positioning bar. When the threaded rod rotates, it moves the threaded sleeve. When the threaded sleeve moves, it drives the sliding sleeve to slide along the surface of the sliding rod through the connector, which increases the stability of the threaded sleeve when it moves. When the threaded sleeve moves, it drives the adjusting frame to rotate along the bottom of the mounting bar through the transmission rod. When the adjusting frame rotates, it can drive the spray head to adjust the spray angle through the second steel pipe. This makes the multi-directional adjustment of this spraying device very convenient, without the need for the operator to push the whole device for adjustment, and it has a very good effect.
