[0002] Mine tunnels are a series of passages excavated in the ground for the purpose of mining mineral resources, ventilation, transportation, pedestrians, laying pipelines and installing equipment during mining. In the process of building mine tunnels, a large amount of tunnel floor needs to be laid. In the process of tunnel floor construction, the ground needs to be smoothed to ensure the flatness of the floor.

[0003] Due to the relatively small space of mine tunnels and the special environment underground in mines, there is a large amount of flammable and explosive dust, which makes the finishing devices on the market unusable. In the existing mine tunnel floor construction process, the floor finishing is usually done manually by workers using a trowel, which results in high labor intensity for the workers and low efficiency of tunnel floor finishing.

[0004] Therefore, a pneumatic concrete floor finishing machine is now developed that can improve the finishing efficiency of mine tunnel floor, reduce the intensity of workers, and protect the pneumatic vibrator. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] A pneumatic concrete floor finishing machine, such as Figure 1 and Figure 2 As shown, it includes a vibration plate 1, a support block 2, a pulling frame 3, a pneumatic vibrator 4, a connecting pipe 5 and a protective mechanism 6. Three support blocks 2 are connected to the upper side of the vibration plate 1. The pulling frame 3 is rotatably connected between the support blocks 2. The pulling frame 3 is provided with a pull ring for easy pulling. The pulling frame 3 is a hollow structure. The left and right upper sides of the vibration plate 1 are connected to left and right pneumatic vibrators 4. A connecting pipe 5 is connected between the two vibrators on the left, and a connecting pipe 5 is also connected between the two pneumatic vibrators 4 on the right. The leftmost and rightmost pneumatic vibrators 4 are both connected to the pulling frame 3 by connecting pipes 5. A protective mechanism 6 is provided on the vibration plate 1.

[0021] like Figure 1 and Figure 3 As shown, the protection mechanism 6 includes a protection cover 61, a fan 62, a support frame 63, a wedge frame 64 and a telescopic spring 65. The left and right parts of the vibration plate 1 are rotatably connected to the protection cover 61, and the upper side of the protection cover 61 is connected to the left and right fans 62. The left and right sides of the front of the vibration plate 1 are connected to the support frame 63, and the support frame 63 is slidably connected to the wedge frame 64. The wedge frame 64 is connected to the connected support frame 63 with a telescopic spring 65, and the wedge frame 64 is clamped with the adjacent protection cover 61.

[0022] When using the utility model, the vibration plate 1 is first moved to the area of ​​the mine tunnel floor to be collected by the pulling frame 3, and then the pulling frame 3 is connected to the air inlet pipe, so that the wind flows through the pulling frame 3 and then flows through the pneumatic vibrator 4 through the connecting pipe 5, thereby making the pneumatic vibrator 4 vibrate and making the vibration plate 1 vibrate, and then the pulling frame 3 is moved to move the vibration plate 1 to collect the tunnel floor. When collecting the tunnel floor, the protective cover 61 is rotated downward to close with the vibration plate 1. When the protective cover 61 is rotated downward, the wedge-shaped frames 64 are squeezed on the support frame 63 to slide away from each other. The telescopic spring 65 is squeezed and contracted. After the protective cover 61 continues to rotate downward and disengage from the wedge frame 64, the telescopic spring 65 rebounds, driving the wedge frame 64 to reset and clamp the protective cover 61 to fix it, so that the protective cover 61 can shield and protect the pneumatic vibrator 4 to prevent cement from splashing during the finishing process and causing damage to the pneumatic vibrator 4, thereby improving the finishing efficiency of the mine tunnel floor, reducing the intensity of the staff, and protecting the pneumatic vibrator 4. After the protective cover 61 is closed with the vibration plate 1, the fan 62 is started to dissipate heat from the pneumatic vibrator 4.

[0023] like Figure 1 and Figure 4 As shown, an adjustment mechanism 7 is also included, and the adjustment mechanism 7 includes a rotating plate 71, a connecting frame 72, a pulling plate 73 and a limiting frame 74. Five rotating plates 71 are rotatably connected to the upper side of the protective cover 61, the left side of the left rotating plate 71 is connected to the connecting frame 72, the right side of the right rotating plate 71 is connected to the connecting frame 72, and the pulling plates 73 are rotatably connected between adjacent connecting frames 72. The front side of the protective cover 61 is rotatably connected to the limiting frame 74, and the limiting frame 74 is snap-fitted with the adjacent pulling plate 73. The limiting frame 74 is an L-shaped structure.

[0024] The adjusting mechanism 7 of the present device can be used to dissipate heat and prevent dust from the pneumatic vibrator 4. When the tunnel floor is being finished, the pulling plate 73 is moved forward, the connecting frame 72 is rotated, and the rotating plate 71 is rotated and opened. The limiting frame 74 is rotated to engage with the pulling plate 73, and the pulling plate 73 is limited and fixed, so that the connecting frame 72 and the rotating plate 71 are fixed, and then the fan 62 is started to dissipate heat inside the protective cover 61. After the floor is finished, the limiting frame 74 is rotated downward to disengage from the pulling plate 73, and the rotating plate 71 is reset under the action of gravity and closed with the protective cover, so that the connecting frame 72 and the pulling plate 73 are reset, and the protective cover is covered to prevent dust from entering the protective cover and affecting the normal use of the pneumatic vibrator 4. The rotating plate 71 can be adjusted to dissipate heat when the pneumatic vibrator 4 is in use and to prevent dust after the pneumatic vibrator 4 is used.
