For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0021] The following is a detailed description of the present utility model in conjunction with Figures 1 to 3 the present utility model.

[0022] An impact-resistant protection device for explosive blasting in non-metallic mines includes a base 1. A connecting column 101 is arranged at the top of the base 1. The top of the connecting column 101 is hingedly connected with a protection plate 2. An articulated block 102 is arranged at the top of the base 1. A chute 201 is arranged at the bottom of the protection plate 2. A hinge rod 2011 is connected to the middle of the chute 201. The hinge rod 2011 is connected with the articulated block 102. A buffer groove 202 is arranged at the top of the protection plate 2. A buffer assembly is connected to the middle of the buffer groove 202. The buffer assembly deflects and resets in the buffer groove 202 under force. One end of the hinge rod 2011 is hingedly connected in the chute 201, and the hinged end of the hinge rod 2011 is slidably connected in the chute 201. The hinge rod 2011 is an electric telescopic rod. The buffer groove 202 is an "inverted" shaped opening at the top of the protection plate 2.

[0023] First, move the base 1 to the designated area, and then rotate the motor on one side of the articulated block 102 to control the deflection of the hinge rod 2011, thereby driving the protection plate 2 to deflect and stand up to provide protection and blockage in the facing direction. At the same time, the hinge rod 2011 will cooperate with the angle change of the protection plate 2 during deflection through the movement of one end along the chute 201. At the same time, the telescopic setting of the hinge rod 2011 itself can also cooperate with the angle deflection of the protection plate 2.

[0024] Furthermore, the buffer assembly includes a socket rod 2021, a telescopic column 2022, an impact plate 203, a return spring 2031, a socket ring 2032, and a deflection groove 2033. The socket rod 2021 is a round rod arranged at the middle line of the middle of the buffer groove 202. The telescopic column 2022 is arranged on both sides of the socket rod 2021 in the middle of the buffer groove 202. The impact plate 203 is connected to the middle of the buffer groove 202. The return spring 2031 is arranged at the bottom near one end of the impact plate 203. The socket ring 2032 is arranged at the end of the impact plate 203 away from the return spring 2031. The deflection groove 2033 is arranged at the bottom of the impact plate 203. The impact plate 203 is two plates connected to both sides of the socket rod 2021 through the socket ring 2032. One end of the two impact plates 203 away from the socket ring 2032 is connected to the buffer groove 202 through the return spring 2031. The deflection groove 2033 is an arc-shaped groove at the bottom of the impact plate 203, and the deflection groove 2033 is hingedly connected to the telescopic column 2022.

[0025] At the same time, during the protection process of the protective plate 2, when the impact generated by the blast causes the crushed stones to impact the protective plate 2, the crushed stones will impact the impact plate 203 in the buffer groove 202. When the crushed stones impact the impact plate 203 and exert pressure, the impact plate 203 will be forced to tilt and deflect through the return spring 2031 at one end, and the end away from the return spring 2031 is connected to the sleeve rod 2021 through the sleeve ring 2032, so that the deflection of the impact plate 203 is carried out through one end along the sleeve rod 2021, so that the impact plate 203 will be in a tilted state. Through the tilted state of the impact plate 203, the crushed stones impacting the surface will be guided by the inclined surface, so that part of the force of the crushed stones will be guided to one side, so that the crushed stones will slide out, and the impact force will not be directly applied to the impact plate 203. At the same time, the contraction and reset of the return spring 2031 when it is under force can also buffer the impact of the crushed stones to a certain extent.

[0026] At the same time, the bottom of the impact plate 203 is also connected to the telescopic column 2022 through the deflection groove 2033 to provide a certain degree of stable support, so that the deflection and inclination of the impact plate 203 are more stable.

[0027] The following is a specific implementation process of the utility model. First, the base 1 is moved to the specified area, and then the motor on one side of the hinge block 102 is controlled to rotate to deflect the hinge rod 2011, thereby driving the protective plate 2 to deflect and make it stand upright, and provide protection in the opposite direction. At the same time, the hinge rod 2011 will cooperate with the angle change of the protective plate 2 during deflection by moving one end along the slide groove 201. At the same time, the telescopic setting of the hinge rod 2011 itself can also cooperate with the angle deflection of the protective plate 2. At the same time, during the protection process of the protective plate 2, when the impact generated by the blasting causes the gravel to impact the protective plate 2, the gravel will impact the impact plate 203 in the buffer groove 202. When the gravel impacts When pressure is applied to the impact plate 203, the impact plate 203 is forced to be tilted and deflected through the return spring 2031 at one end, and the end away from the return spring 2031 is connected to the sleeve rod 2021 through the sleeve ring 2032, so that the deflection of the impact plate 203 is carried out through one end along the sleeve rod 2021, so that the impact plate 203 will be in a tilted state. Through the tilted state of the impact plate 203, the gravel impacting the surface will be guided by the inclined surface, so that part of the force of the gravel will be guided to one side, so that the gravel will slide out, and the impact force will not be directly applied to the impact plate 203. At the same time, the contraction and reset of the return spring 2031 when it is under force can also provide a certain buffer for the impact of the gravel.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
