DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1-Figure 10 A directional blasting device with vibration reduction function, comprising two first baffles 1, a second baffle 2 is arranged between both ends of the first baffle 1, a fixed cavity 4 is arranged on the first baffle 1, the fixed cavity 4 is divided into a plurality of buffer grooves 21 by a cross plate, a buffer block 7 is slidably arranged in each buffer groove 21, the outer surface of the fixed cavity 4 is slidably covered with a movable cover 5, the movable cover 5 and the fixed cavity 4 form a storage space, and the storage space is filled with water;

[0034] Each buffer block 7 is connected to the movable cover 5 through an elastic mechanism, which includes two connecting shafts 23 and two springs 22 that are rotatably connected together, and a plurality of water pipes 6 are connected to the movable cover 5; the first baffle 1 and the second baffle 2 are connected through a plurality of movable mechanisms, which include two rotating shafts 14 that are rotatably connected together and an elastic strip 16 that is elastically connected between the two rotating shafts 14; an angle is formed between the two first baffles 1, and there is a gap between the ends that are close to each other, and connecting mechanisms are provided at both ends of the gap, and the connecting mechanisms include a corrugated rubber sheet 28 and a corrugated airbag 27; two clamping plates 29 are clamped between the two first baffles 1, and an explosive tube 3 is clamped between the two clamping plates 29, and a sealing block 11 is fixedly connected to the surface of the explosive tube 3, and the sealing block 11 is fitted with the clamping plate 29.

[0035] A first slide groove 20 is provided at the edge of the first baffle 1, and a second slide groove 12 is provided at the edge of the second baffle 2. Slide blocks 13 used in conjunction with the rotating shaft 14 are slidably connected in the first slide groove 20 and the second slide groove 12. One end of the two rotating shafts 14 are rotatably connected to the two slide blocks 13 respectively. Both ends of the elastic strip 16 are fixedly connected with an insertion shaft 17 with a circular cross-section. Moving openings 15 are provided on the two rotating shafts 14, and the insertion shaft 17 is inserted in the moving openings 15. The first baffle plate 1 and the second baffle plate 2 can be connected together through the movable mechanism, and the movable mechanism can move back and forth on the first slide groove 20 and the second slide groove 12 of the first baffle plate 1 and the second baffle plate 2. The movable movable mechanism has a buffering effect on the impact force during the blasting process, wherein the elastic strip 16 is elastic and can be deformed, and the elastic strip 16 can also move back and forth on the movable port 15 through the plug-in shaft 17. The movable mechanism provides sufficient movable space to alleviate the impact force generated during the blasting process. When blasting, the impact effect can be alleviated by moving and deforming. At the same time, the first baffle plate 1 and the second baffle plate 2 block the main impact force from the blasting, control the blasting range, and play a role in gathering energy.

[0036] The ends of the two first baffles 1 that are away from each other are both provided with baffle bars 8, the surfaces of the baffle bars 8 are provided with grooves, a fixing bar 9 for limiting is fixedly provided on the baffle bars 8, and a connecting plate 10 is rotatably connected to one side of the baffle bars 8. When used for blasting, the device can be directly covered at the position of the blasting point, or the connecting plate 10 can be connected to the blasting plane by bonding to achieve the fixed installation effect of the device.

[0037] A folding plate 24 is provided at one end of the two first baffles 1 close to each other, and a bayonet 25 for installing a connecting mechanism is provided on the folding plate 24. Connecting pieces 26 are fixedly connected to both ends of the corrugated airbag 27, and a T-shaped clamping block 30 is fixedly provided on the connecting piece 26. The T-shaped clamping block 30 is clamped in the bayonet 25. One end of the corrugated rubber sheet 28 is fixedly connected to the surface of the two connecting pieces 26, and the other end is fixedly connected to the surface of the clamping plate 29. A connecting mechanism is provided between the two first baffles 1, and the connecting mechanism includes an elastic corrugated airbag 27 and a corrugated rubber sheet 28. The corrugated airbag 27 and the corrugated rubber sheet 28 can be stretched and deformed, and can be buffered by deformation during explosion. The gap formed between the corrugated airbag 27 and the corrugated rubber sheet 28 can release pressure during the explosion process, reduce pressure, and avoid the influence of excessive pressure on the device during explosion, and also play a buffering role.

[0038] A clamping mechanism is connected between the two clamping plates 29, and the clamping mechanism includes two clamping shafts 31 rotatably connected together through a U-shaped shaft 33. An opening 36 is provided at the connection between the two clamping shafts 31. A threaded shaft 32 is threadedly inserted on the U-shaped shaft 33. An adjusting block 35 is rotatably connected to the lower end of the threaded shaft 32. Both sides of the adjusting block 35 are respectively connected to the two clamping shafts 31 through multiple adjusting shafts 34. One end of the two clamping shafts 31 respectively abuts against the surface of the two clamping plates 29. When the clamping plate 29 is installed on the first baffle 1, the two clamping plates 29 are brought close to each other through the clamping mechanism. An explosive tube 3 is arranged between the two clamping plates 29. The explosive is transported into the blasting hole through the explosive tube 3. The staff changes the angle between the clamping shaft 31 and the adjusting shaft 34 by rotating the threaded shaft 32. The smaller the two angles are, the tighter the clamping effect of the clamping plate 29 is, and the smaller the diameter of the explosive tube 3 that can be clamped and fixed is. Conversely, the explosive tube 3 with a larger diameter can be clamped and fixed. The threaded shaft 32 is threaded through the U-shaped shaft 33. The adjusting block 35 rotatably connected to the lower end of the threaded shaft 32 is limited in angle by the adjusting shaft 34. Rotating the threaded shaft 32 can change the distance of the adjusting block 35 relative to the U-shaped shaft 33.

[0039] One of the connecting shafts 23 is rotationally connected to the surface of the buffer block 7, and the other connecting shaft 23 is rotationally connected to the inner surface of the mobile cover 5, and the spring 22 is connected between the buffer block 7 and the mobile cover 5. When blasting, the impact force generated by the blasting will directly act on the buffer block 7, so that the spring 22 is compressed, and at the same time, the two connecting shafts 23 will rotate relative to each other, and the mobile cover 5 will move relative to the fixed cavity 4. Since water is filled between the fixed cavity 4 and the mobile cover 5, the water and the spring 22 can both unload part of the pressure from the blasting, playing a role in buffering the pressure reduction. At the same time, since the water can also flow outward through the water pipe 6, the pressure generated on the water can eventually be unloaded outward, thereby effectively playing a role in buffering the pressure.

[0040] A limit block 18 is provided at one end of the slider 13, and the limit block 18 plays a role of limiting. A round block 19 is provided at the end of the plug shaft 17 away from the elastic strip 16, and the round block 19 also plays a role of limiting. A mounting plate 37 is symmetrically fixedly connected to one side of one of the fixed cavities 4, and a hole is provided on the mounting plate 37. When blasting, external mechanical equipment can be connected to the mounting plate 37 through screws passing through the holes, so that the device can be placed on the surface of the blasting earth and stone. The outer surface of the end of the explosive tube 3 is provided with a thread. The explosive tube 3 can be connected to the external environment through a thread, and can also be closed by installing a cover through a thread. If the explosive tube 3 is not used, the two clamping plates 29 can be clamped together by a clamping mechanism to close the gap.

[0041] When preparing for blasting, the device can be directly pasted on the surface of the blasting earth and stone, and the connecting plate 10 is glued to the surface of the earth and stone. The explosives for blasting can be directly placed in the blasting hole in advance, or the explosives can be filled into the blasting hole through the explosive tube 3. Since the device is covered on the outer surface of the blasting hole, it can gather energy to a certain extent and limit the impact force of the blasting within the range of the blasting hole. It can gather energy for directional blasting, improve the blasting quality and efficiency, and effectively control the blasting range.

[0042] When blasting, the impact force generated by the blasting will directly act on each buffer block 7, generating impact force on the buffer block 7, compressing the spring 22, and at the same time causing the movable cover 5 to move outward relative to the fixed cavity 4. The pressure generated on the buffer block 7 will be transmitted to the water. The presence of water can effectively unload the pressure. At the same time, the change in the storage space will squeeze the water, which can be transported outward through the water pipe 6. The squeezed water and the deformed spring 22 can effectively buffer the pressure generated during the blasting.

[0043] A second baffle plate 2 is installed on both sides of the two first baffle plates 1. A plurality of movable mechanisms are arranged between the first baffle plate 1 and the second baffle plate 2. The slider 13 in the movable mechanism can slide in the first slide groove 20 or the second slide groove 12. When the blasting impact force acts on the second baffle plate 2, the second baffle plate 2 can adaptively shift the angle to unload the force. At the same time, the elastic strip 16 can be deformed. The gap at the connection between the first baffle plate 1 and the second baffle plate 2 can be adaptively increased. The structure with the gap can relieve pressure. The two ends of the elastic strip 16 can slide on the rotating shaft 14 through the plug-in shaft 17 to adapt to the angle change between the two rotating shafts 14.

[0044] A movable mechanism is provided in the gap between the two first baffles 1. The corrugated airbag 27 and the corrugated rubber sheet 28 in the movable mechanism can be stretched and deformed. After the explosion, the corrugated airbag 27 and the corrugated rubber sheet 28 can be deformed to ensure the stability of the structure. At the same time, the semi-closed state can control the explosion range and control the impact force of the explosion around the explosion point. The gaps between the various components can relieve pressure and buffer to ensure safety.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
