[0004] The aforementioned patent documents have the advantages of facilitating device movement and transportation. However, the protective equipment is only protected by a metal mesh cover, which has poor protective capabilities. For flying stones with high speed and mass, the metal mesh cover may not be able to completely block them. The flying stones may penetrate the metal mesh cover or cause the mesh cover to deform too much and lose its protective function. Utility Model Content
[0005] The purpose of this utility model is to solve the shortcomings of existing protective equipment that relies solely on metal mesh for protection, which has poor protective capabilities. For flying rocks with high speed and mass, the metal mesh may not be able to completely block them, and the flying rocks may penetrate the metal mesh or cause the mesh to deform excessively and lose its protective function. Therefore, a mine blasting protection device is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A mine blasting protection device includes a protection device body, with evenly distributed columns fixedly connected to the outer walls of both sides of the protection device body. A metal mesh cover is provided around the columns, and an installation groove is opened on the outer wall of the columns. A replaceable buffer plate is provided in the installation groove, and a fixed shaft is provided on the outer wall of the columns. A baffle is rotatably connected to the fixed shaft. A fixed buffer plate is fixedly connected to the closed end of the protection device body, and an air filter pipe is provided at the top of the protection device body.
[0008] Preferably, each column is provided with two symmetrically distributed fixed shafts, which are located at the beginning and end of the mounting groove.
[0009] Preferably, the fixed buffer plate has a window, and the window is connected to a protective door via a hinge.
[0010] Preferably, the inner wall of the air filter pipe is provided with a filter screen, and a fixing plate is provided at the connection between the air filter pipe and the protective equipment body. A motor is fixedly connected to the bottom end of the fixing plate, and a fan blade is rotatably connected to the top end of the fixing plate.
[0011] Preferably, the air filter tube is L-shaped, and the output end of the motor passes through the outer wall of the fixing plate and is fixedly connected to the fan blade.
[0012] Preferably, a sliding plate is provided at the opening of the protective device body, and a stop block is fixedly connected to the bottom of the outer wall of the sliding plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. When in use, this utility model can be made so that when a flying stone penetrates the metal mesh cover or deforms the mesh cover, the buffer material can further absorb the energy of the flying stone, thereby enhancing the protective force of the metal mesh cover and making it more protective, thus preventing larger flying stones from passing through the metal mesh cover.
[0015] 2. In use, this utility model, through its air filter pipe, motor, fan blades, and filter screen, enables the protective equipment located inside the mine to filter the air in a timely manner. Reversing the motor reverses the airflow, blowing away impurities clogging the filter screen. This reduces filter clogging and extends the filter's lifespan. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Reference Figures 1-4 A mine blasting protection device includes a protection device body 1, with columns 2 evenly distributed and fixedly connected to the outer walls of both sides of the protection device body 1. A metal mesh cover 3 is provided around the columns 2. An installation groove 4 is provided on the outer wall of the columns 2. A replaceable buffer plate 5 is provided in the installation groove 4. A fixed shaft 6 is provided on the outer wall of the columns 2. A baffle 7 is rotatably connected to the fixed shaft 6. A fixed buffer plate 8 is fixedly connected to the closed end of the protection device body 1. An air filter pipe 9 is provided at the top of the protection device body 1.
[0023] It should be noted that the replaceable buffer plate 5 and the fixed buffer plate 8 are existing technologies. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.
[0024] Furthermore, each column 2 is provided with two symmetrically distributed fixed shafts 6, which are located at the beginning and end of the mounting groove 4.
[0025] The replaceable buffer plate 5 can be removed from the mounting slot 4 for replacement by rotating the baffle 7 so that the longer outer wall of the baffle 7 is separated from the replaceable buffer plate 5. Both the replaceable buffer plate 5 and the fixed buffer plate 8 are made of rubber.
[0026] Furthermore, a window 10 is provided on the fixed buffer plate 8, and a protective door 11 is connected to the window 10 by a hinge.
[0027] The protective door 11 opens from the inside and has a built-in limit device, which prevents the protective door 11 from opening easily after it is closed, thus preventing gravel from entering the protective equipment through the window 10.
[0028] Furthermore, the inner wall of the air filter pipe 9 is provided with a filter screen 12, and a fixing plate 13 is provided at the connection between the air filter pipe 9 and the protective equipment body 1. A motor 14 is fixedly connected to the bottom end of the fixing plate 13, and a fan blade 15 is rotatably connected to the top end of the fixing plate 13.
[0029] The motor 14 can be powered by an external power source. The motor 14 is a stepper motor that can rotate in both directions and can simultaneously draw in air and expel air.
[0030] Furthermore, the air filter tube 9 is L-shaped, and the output end of the motor 14 passes through the outer wall of the fixing plate 13 and is fixedly connected to the fan blade 15.
[0031] Multiple filters 12 can be installed inside the air filter tube 9 to improve the filtration effect.
[0032] Furthermore, a sliding plate 16 is provided at the opening of the protective equipment body 1, and a stop block 17 is fixedly connected to the bottom of the outer wall of the sliding plate 16.
[0033] The slide plate 16 can be slid upwards to open, and the stop block 17 can prevent the slide plate 16 from detaching from the protective equipment body 1.
[0034] Working principle: When using this device, first insert the replaceable buffer plate 5 into the mounting slot 4, then manually rotate the baffle 7 so that the longer end of the baffle 7 abuts against the replaceable buffer plate 5. Then connect the motor 14 to the external power supply and start the motor 14. The motor 14 drives the fan blade 15 to rotate. The fan blade 15 rotates in the forward direction and blows air into the air filter pipe 9 to blow away the impurities on the filter screen 12. Then the motor 14 drives the fan blade 15 to rotate in the reverse direction and draws outside air from the air filter pipe 9 into the protective equipment body 1.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
