[0001] The utility model relates to the technical field of mine blasting and crushing rock protection, in particular to a blasting and crushing rock protection device. Background Art
[0002] When mining corresponding resources, blasting will be carried out according to the demand and the actual environment. During the blasting, air shock waves and shattered rocks will be scattered. In order to avoid injuries to personnel during blasting, construction workers generally use blasting and shattering rock protection devices to protect themselves, so as to avoid injuries caused by flying shattered rocks. However, the existing blasting and shattering rock protection devices still have some shortcomings. For example, they cannot be quickly and effectively connected to the ground during use. Most of them are supported manually. When shattered rocks come, they are supported manually to resist the protection devices, thereby offsetting the impact force of the shattered rocks. At the same time, the existing blasting and shattering rock protection devices are not convenient to move, because most of them are made of metal materials, which are heavy and more labor-intensive for one person to carry. Therefore, we propose a blasting and shattering rock protection device. Utility Model Content

[0019] Embodiment 1:
[0020] See also Figure 1-3 The utility model provides a technical solution: a blasting and crushing stone protection device, comprising a protective plate 1, the front and rear end surfaces of the right side of the protective plate 1 are both provided with side protective plates 2, and the bottom of the protective plate 1 is sequentially provided with ground plugs 4 from the inside to the outside. When blasting and mining are carried out in a mine, before blasting, the staff can fix the protective plate 1 in a suitable position through the ground plugs 4, and then the staff hides behind the protective plate 1, so that when blasting and crushing stone are carried out, the protective plate 1 can be protected and protected to avoid being injured by the impact of crushed stone. Connecting rods 5 are arranged around the left side of the protective plate 1, and a buffer plate 6 is connected to the left side of the connecting rod 5. An arc-shaped groove 7 is arranged on the left side of the buffer plate 6, and a buffer pad 8 is arranged in the arc-shaped groove 7. When the flying crushed stone during the blasting and mining of the mine comes toward the protective plate 1, the crushed stone will hit the arc-shaped groove 7 on the outside of the buffer plate 6, and the inner wall of the arc-shaped groove 7 will buffer the impact force brought by the crushed stone through the provided buffer pad 8, and the top of the protective plate 1 A top plate 9 is provided at the top, and the top plate 9 can prevent the rubble falling from a height from hitting the staff hiding behind the protective plate 1. A hinge 10 is provided between the left top of the top plate 9 and the left top of the protective plate 1. The protective plate 1 and the top plate 9 are hinged by the hinge 10. Handles 11 are provided on the front and rear end surfaces of the right side of the top plate 9, and moving wheels 12 are provided on the right bottom of the side protective plate 2. When it is necessary to move the entire protective device over a short distance, the staff can flip the top plate 9 through the hinge 10 to rotate and adjust the top plate 9 to the top left of the protective plate 1, and then tilt the entire protective plate 1 to the right until the moving wheel 12 touches the ground. In this way, the entire device can be pulled to move by the handle 11, and handrails 13 are provided on the front and rear end surfaces of the middle right side of the protective plate 1, and pedals 14 are provided on the front and rear end surfaces of the right bottom of the protective plate 1. When the staff stands on the back of the protective plate 1, they can hold the handrail 13 and then step one foot on the pedal 14, which can increase the overall stability.
[0021] Among them, preferably, the connecting rod 5 includes a fixed rod 15, the right side of the fixed rod 15 is fixedly connected to the protective plate 1, the left side of the fixed rod 15 is sleeved with a movable rod 16, and the left side of the fixed rod 15 is provided with a mounting hole 17 matching the movable rod 16, a damper 18 is provided on the right side of the inner cavity of the mounting hole 17, and a spring 19 is provided between the movable rod 16 and the damper 18.
[0022] Preferably, the side protective plates 2 are inclined outward at forty-five degrees and are arranged on the right side of the protective plate 1. This arrangement can increase the protection range of the entire protective device. The side protective plates 2 are provided with observation windows 3, and the observation windows 3 are configured as transparent tempered glass. Through the observation windows 3, the staff can observe the external situation conveniently, so as to make corresponding treatment in time.

When encountering some ground where the ground plugs 4 cannot be inserted, the staff can remove the ground plugs 4 from the bottom of the protective plate 1 by rotating it, and then directly place the protective plate 1 on the ground.
[0024] Embodiment 2:
[0025] Reference Figure 1 , this embodiment is different from the first embodiment in that: an adhesive layer is provided between the buffer pad 8 and the inner wall of the arc-shaped groove 7, so that when the buffer pad 8 is damaged and cannot be used, it can be torn off and replaced with a new buffer pad 8. The buffer pad 8 includes a rubber buffer layer, and the outer wall of the rubber buffer layer is provided with a sponge protective layer. The rubber buffer layer and the sponge protective layer can effectively buffer and reduce the impact force caused by the impact of gravel, and at the same time, it can also protect the buffer plate 6 to prevent it from being directly impacted by gravel and thus being damaged after a long time; the length of the top plate 9 from the inside to the outside is the same as the length of the protective plate 1 from the inside to the outside, so that the staff can be fully protected from the top. The top of the top plate 9 is set to be lower on the left and higher on the right. This setting can make the top of the top plate 9 reach a slope state, so that some small fallen gravel will automatically roll to the left, so as to reduce the accumulation of gravel on the top of the top plate 9; the outer wall of the handrail 13 is wrapped with an anti-skid handlebar tape, and the anti-skid handlebar tape can increase the comfort of the staff when holding the handrail 13. The inner angle between the pedal 14 and the protective plate 1 is set to forty-five degrees. This setting can make the staff step on the pedal 14 to resist the protective plate 1. The surface of the pedal 14 is evenly provided with anti-skid convex patterns. The anti-skid convex patterns can increase the anti-skid effect when the staff steps on it, and avoid the phenomenon of slipping on the soles of the shoes.
[0026] The electrical appliances mentioned in this article are all connected to an external power source through wires.
