[0047] (1) When the hammering block needs to hit the ground, the motor is started to drive the chain to rotate, the hammering block is lifted by the jacking block, and the hammering block is quickly lowered by the driving assembly to hit the ground to generate shock waves. When the hammering block is lifted for the first time, the inclined spring block is pressed to move, the spring clamping rod is inserted into the clamping block through the clamping assembly, and the inclined spring block is limited to return. When the hammering block hits the ground, the spring clamping rod is separated from the clamping block through the clamping assembly, the inclined spring block blocks the hammering block, and when the hammering block hits the ground and rebounds, the inclined spring block is pressed again.

[0049] (3) When the hammering block is lifted by the jacking block, the inclined spring block is pressed to move, the spring pressing plate is pressed to move the hammering block through the pressing assembly. With the continuous lifting of the hammering block, the hammering block is separated from the spring pressing plate. At this time, the rebound force of the spring pressing plate is released, the spring pressing plate drives the pushing rod and the arc inclined plate to move. When the jacking block rises, the ball head pushing rod also rises. With the continuous lifting of the ball head pushing rod, the ball head pushing rod presses the arc inclined plate, drives the pushing rod and the spring pressing plate to move, so that the spring pressing plate does not contact the hammering block when the hammering block falls for the first time.

[0096] Among them, the hammer block 121 also drives the compression rod 223 to rise, causing the compression rod 223 to separate from the rocker plate 225. At this time, the thrust on the spring-loaded locking rod 226 disappears. Since the spring-loaded locking rod 226 was previously in a compressed state, its rebound force is released, causing it to return to its original position. When the inclined spring block 213 moves, it also drives the piston plate 212 and the locking block 214 to move synchronously. As the locking block 214 continues to move, the inclined surface of the locking block 214 will press against the inclined surface of the spring-loaded locking rod 226, lifting the spring-loaded locking rod 226 and accumulating rebound force. As the locking block 214 continues to move, when the notch inside the locking block 214 aligns with the spring-loaded locking rod 226, such as Figure 7 As shown in state I, the spring force of the spring latch 226 will be released, allowing the spring latch 226 to insert into the notch. At this time, the inclined surface of the hammer block 121 will also separate from the inclined surface of the inclined spring block 213, and the squeezing force on the inclined spring block 213 will disappear. As the hammer block 121 continues to rise, the inclined spring block 213 will separate from the hammer block 121. Since the spring latch 226 is inserted into the locking block 214, it will restrict the return of the inclined spring block 213.

[0097] When the hammer block 121 descends and impacts the ground, it causes the compression rod 223 to re-engage with the rocker arm 225, pushing the rocker arm 225 to rotate. This causes the side of the rocker arm 225 in contact with the compression rod 223 to descend, while the other side rises. The rising side pushes the spring-loaded locking rod 226 upward, compressing it and separating it from the locking block 214. At this point, the rebound force of the inclined spring block 213 is released, allowing it to return to its original position. When the hammer block 121 impacts the ground and rebounds, it will compress the inclined spring block 213 again. 3. Move piston plate 212 and drive piston plate 222 to move via locking block 214. When piston plate 212 moves, it will squeeze hydraulic oil 1 in hydraulic groove 211 and enter the irregular groove 215. It will enter the right side of piston plate 212 through irregular groove 215. Since irregular groove 215 has multiple complex flow channels, hydraulic oil 1 will be forced to flow by the asymmetric branches in irregular groove 215, which will change the flow path of hydraulic oil 1 and cause multiple streams of hydraulic oil 1 to collide, which will slow down the flow speed of hydraulic oil 1, thereby slowing down the moving speed of piston plate 212.

[0098] Simultaneously, as piston plate 222 moves, it compresses the gas on its left side, creating high pressure. At the same time, it increases the space on the right side of piston plate 222, creating negative pressure and attracting force on it. Figure 6The sealing ring two in the hydraulic tank 211 avoids the hydraulic oil one in the hydraulic tank 211 from being attracted into the air pressure tank 221 by the negative pressure in the air pressure tank 221, generates high pressure on the left side of the piston plate two 222 and negative pressure on the right side, increases the moving resistance of the piston plate two 222, simultaneously, slows down the moving speed of the piston plate one 212, makes the moving resistance of the inclined spring block 213 stronger, blocks the rising of the hammer block 121, reduces the rebound height of the hammer block 121, effectively prevents the rebound height of the hammer block 121 from being too high to generate strong impact force to hit the ground again, interferes with the shock wave formed by the first impact, ensures the accurate reflection signal and the accuracy of the exploration.

[0099] The extrusion assembly 31 comprises two connecting rods one 313 arranged at the front and back of the frame 111, the inner walls of the two connecting rods one 313 are slidably connected with the side walls of the two push plates 312, and the inner walls of the two push plates 312 are slidably connected with the outer walls of the two spring pressure plates 311.

[0100] The side walls of the inclined spring block 213 are fixedly connected with two connecting rods two 314, the side walls of the two connecting rods two 314 are rotatably connected with connecting rods 315, and the inner walls of the two connecting rods 315 are rotatably connected with the side walls of the two connecting rods one 313.

[0101] The inner walls of the frame 111 are fixedly connected with two hydraulic cylinders 316, the inner walls of the two hydraulic cylinders 316 are slidably connected with piston rods 317, and the side walls of the two piston rods 317 are fixedly connected with the side walls of the two push plates 312.

[0102] The inner walls of the two piston rods 317 are provided with communication holes 318, and the inner walls of the two hydraulic cylinders 316 are provided with hydraulic oil two.

[0103] When the inclined spring block 213 moves towards the piston plate one 212, the connecting rod two 314 is driven to move, the connecting rod two 314 drives the connecting rod 315 to rotate, the connecting rod one 313 is pulled to move towards the spring pressure plate 311, the connecting rod one 313 extrudes the push plate 312 to move, the push plate 312 extrudes the spring on the spring pressure plate 311, the spring pressure plate 311 accumulates the rebound force, the spring pressure plate 311 extrudes the hammer block 121, the spring pressure plate 311 extrudes the hammer block 121, which increases the descending resistance of the hammer block 121, slows down the descending speed of the hammer block 121, and makes the hammer block 121 slowly contact with the ground, effectively prevents the hammer block 121 from rebounding and then descending fast, and hits the ground to form multiple small-amplitude rebounds and multiple shock waves, which interferes with the accurate reception of the exploration signal.

[0104] The reset assembly 32 includes two push rods 321 that are slidably connected to the inner wall of the frame 111. The side walls of the two push rods 321 are fixedly connected to the side of the two spring pressure plates 311 away from the hammer block 121.

[0105] Two curved inclined plates 322 are slidably connected to the inner wall of the frame 111. The side walls of the two curved inclined plates 322 are fixedly connected to the side walls of the two push rods 321. Ball-head push rods 323 are fixedly connected to the side walls of the four lifting blocks 122 located on the front and back.

[0106] When the hammer block 121 is lifted by the lifting block 122, it compresses the inclined spring block 213, causing it to move. The inclined spring block 213, through the compression assembly 31, causes the spring pressure plate 311 to compress the hammer block 121. As the hammer block 121 continues to rise, it separates from the spring pressure plate 311. At this point, the rebound force of the spring pressure plate 311 is released, pushing it towards the inclined spring block 213, which in turn moves the push rod 321, causing the curved inclined panel 322 to move closer to the chain 114. As the lifting block 122 rises, it also drives the ball-head push rod 323 to rise. As the ball-head push rod 323 continues to rise, it contacts the inclined surface of the curved inclined panel 322, compressing it and moving it away from the lifting block 122. Figure 12 As shown, the push rod 321 and the spring pressure plate 311 move, causing the spring pressure plate 311 to be compressed again. When the lifting block 122 separates from the hammer block 121, the ball head push rod 323 will continue to squeeze the arc-shaped inclined plate 322. By compressing the spring pressure plate 311 again, the spring pressure plate 311 will not contact the hammer block 121 when it first descends. This effectively prevents the spring pressure plate 311 from squeezing the hammer block 121 when it first descends, slowing down the falling speed of the hammer block 121 and reducing the impact force of the hammer block 121's initial descent. This results in a weaker shock wave from the initial impact, which may affect the signal acquisition of shallow strata.

[0107] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0108] The method of using this shallow seismic exploration equipment includes the following steps:

[0109] S1: Start the equipment: The operator moves the frame 111 to the location where seismic exploration is required. After it is in place, when it is necessary to make the hammer block 121 hit the ground, the motor 113 is started to drive the sprocket rod 112 to rotate, so that the chain 114 rotates.

[0110] S2: Weight rises: The chain 114 drives the lifting block 122 at the bottom to rise. The lifting block 122 at the bottom will contact the protruding part of the hammer block 121, and the lifting block 122 will lift the hammer block 121, causing the hammer block 121 to rise. As the chain 114 continues to rotate, the lifting block 122 will move to the position of the sprocket rod 112 at the top.

[0111] S3: Shockwave formation: As the chain 114 continues to rotate, it will cause the lifting block 122 to separate from the hammer block 121. At this time, the thrust on the hammer block 121 disappears. Due to the weight of the hammer block 121, it will descend rapidly and hit the ground, generating shockwaves. Afterwards, the shockwaves are explored.

[0112] A specific application of this embodiment is as follows: When using this invention, the operator moves the frame 111 to the location where seismic exploration is needed. After moving it into position, when it is necessary for the hammer block 121 to strike the ground, the motor 113 is started to drive the sprocket rod 112 to rotate, causing the chain 114 to rotate. The chain 114 then drives the lifting block 122 located at the bottom to rise. The lifting block 122 located at the bottom will contact the protruding part of the hammer block 121, such as... Figure 4 As shown in position G, the lifting block 122 will lift the hammer block 121, causing the hammer block 121 to rise. As the chain 114 continues to rotate, the lifting block 122 will move to the position of the sprocket rod 112 at the top. The chain 114 continues to rotate, which will cause the lifting block 122 to separate from the hammer block 121. At this time, the thrust on the hammer block 121 disappears. Due to the weight of the hammer block 121, it will fall rapidly and hit the ground, generating shock waves. Afterwards, the shock waves are explored.

[0113] When the hammer block 121 initially rises, its inclined surface compresses the inclined surface of the inclined spring block 213, causing the inclined spring block 213 to move towards the piston plate 212. Simultaneously, accumulating rebound force, the hammer block 121 also drives the compression rod 223 to rise, separating it from the rocker plate 225. At this point, the thrust on the spring-loaded connecting rod 226 disappears. Since the spring-loaded connecting rod 226 was previously under compression, it now... The rebound force of the connecting rod 226 will be released, causing it to return to its original position. As the inclined spring block 213 moves, it will also drive the piston plate 212 and the engaging block 214 to move synchronously. With the continuous movement of the engaging block 214, the inclined surface of the engaging block 214 will press against the inclined surface of the spring-loaded connecting rod 226, lifting the spring-loaded connecting rod 226 and accumulating rebound force. As the engaging block 214 continues to move, when the notch inside the engaging block 214 aligns with the spring-loaded connecting rod 226, such as... Figure 7As shown in state I, the spring force of the spring latch 226 will be released, allowing the spring latch 226 to insert into the notch. At this time, the inclined surface of the hammer block 121 will also separate from the inclined surface of the inclined spring block 213, and the squeezing force on the inclined spring block 213 will disappear. As the hammer block 121 continues to rise, the inclined spring block 213 will separate from the hammer block 121. Since the spring latch 226 is inserted into the locking block 214, it will restrict the return of the inclined spring block 213.

[0114] When the hammer block 121 descends and impacts the ground, it causes the compression rod 223 to re-engage with the rocker arm 225, pushing the rocker arm 225 to rotate. This causes the side of the rocker arm 225 in contact with the compression rod 223 to descend, while the other side rises. The rising side pushes the spring-loaded locking rod 226 upward, compressing it and separating it from the locking block 214. At this point, the rebound force of the inclined spring block 213 is released, allowing it to return to its original position. When the hammer block 121 impacts the ground and rebounds, it will compress the inclined spring block 213 again. 3. Move piston plate 212 and drive piston plate 222 to move via locking block 214. When piston plate 212 moves, it will squeeze hydraulic oil 1 in hydraulic groove 211 and enter the irregular groove 215. It will enter the right side of piston plate 212 through irregular groove 215. Since irregular groove 215 has multiple complex flow channels, hydraulic oil 1 will be forced to flow by the asymmetric branches in irregular groove 215, which will change the flow path of hydraulic oil 1 and cause multiple streams of hydraulic oil 1 to collide, which will slow down the flow speed of hydraulic oil 1, thereby slowing down the moving speed of piston plate 212.

[0115] Simultaneously, as piston plate 222 moves, it compresses the gas on its left side, creating high pressure. At the same time, it increases the space on the right side of piston plate 222, creating negative pressure and attracting force on it. Figure 6 The sealing ring in the middle prevents the hydraulic oil in the hydraulic groove 211 from being attracted by the negative pressure in the pneumatic groove 221 and entering the pneumatic groove 221. This causes high pressure to be generated on the left side of the piston plate 222 and negative pressure to be generated on the right side, increasing the moving resistance of the piston plate 222. At the same time, it slows down the moving speed of the piston plate 212, making the moving resistance of the inclined spring block 213 stronger. This will block the hammer block 121 from rising, reduce the rebound height of the hammer block 121, and effectively prevent the hammer block 121 from rebounding too high and generating a strong impact force, which would then hit the ground again and interfere with the shock wave formed by the initial impact. This ensures accurate reflection signals and guarantees the accuracy of exploration.

[0116] Secondly, when the inclined spring block 213 moves towards the piston plate 212, it will drive the connecting rod two 314 to move, the connecting rod two 314 will drive the connecting rod 315 to rotate, pull the connecting rod one 313 to move towards the spring pressing plate 311, the connecting rod one 313 will squeeze the push plate 312 to move, so that the push plate 312 squeezes the spring on the spring pressing plate 311, so that the spring pressing plate 311 accumulates the elastic force, and the spring pressing plate 311 squeezes the hammer block 121, through the spring pressing plate 311 squeezing the hammer block 121, the descending resistance of the hammer block 121 is increased, the descending speed of the hammer block 121 is slowed down, the hammer block 121 slowly contacts with the ground, effectively preventing the hammer block 121 from rebounding again after the hammer block 121 rebounds, and the hammer block 121 will form multiple small amplitude rebounds after impacting the ground, forming multiple shock waves, interfering with the accurate reception of the exploration signal;

[0117] When the push plate 312 squeezes the spring pressing plate 311, the piston rod 317 will squeeze the hydraulic oil two in the hydraulic cylinder 316, and flow to the left side of the piston rod 317 through the communication hole 318, as shown in Figure 10 When the hammer block 121 rebounds again and descends, the rebounding force of the inclined spring block 213 is released, the connecting rod two 314 is reset, the connecting rod one 313 is reset through the connecting rod 315, at this time, the squeezing force of the push plate 312 disappears, the rebounding force of the spring pressing plate 311 is released, the push plate 312 is reset, the piston rod 317 squeezes the hydraulic oil two again, and flows through the communication hole 318, because the size of the communication hole 318 is small, the flow resistance of the hydraulic oil two is increased, so that the reset speed of the push plate 312 is slowed down, avoiding the hammer block 121 from separating from the inclined spring block 213, the connecting rod one 313 quickly resets, the push plate 312 resets, the squeezing force of the spring pressing plate 311 on the hammer block 121 is quickly reduced, and the squeezing of the hammer block 121 is affected;

[0118] Secondly, when the hammer block 121 is lifted by the jacking block 122, it will squeeze the inclined spring block 213 to move, the inclined spring block 213 will squeeze the spring pressing plate 311 through the squeezing assembly 31 to squeeze the hammer block 121, with the continuous rising of the hammer block 121, the hammer block 121 will separate from the spring pressing plate 311, at this time, the rebounding force of the spring pressing plate 311 is released, the spring pressing plate 311 moves towards the inclined spring block 213, drives the push rod 321 to move, and drives the arc inclined plate 322 to move, so that the arc inclined plate 322 approaches the chain 114, when the jacking block 122 rises, the ball head push rod 323 also rises, with the continuous rising of the ball head push rod 323, the ball head push rod 323 will contact with the inclined surface of the arc inclined plate 322, squeeze the arc inclined plate 322, and make the arc inclined plate 322 away from the jacking block 122, as shown in Figure 12As shown, the driving push rod 321 and the spring pressing plate 311 are moved, so that the spring pressing plate 311 is in the compressed state again, when the jacking block 122 is separated from the hammering block 121, the ball head push rod 323 continuously extrudes the arc-shaped inclined surface plate 322, by making the spring pressing plate 311 in the compressed state again, when the hammering block 121 is initially lowered, the spring pressing plate 311 does not contact the hammering block 121, effectively preventing the spring pressing plate 311 from extruding the hammering block 121 when the hammering block 121 is initially lowered, slowing down the falling speed of the hammering block 121, reducing the impact force of the hammering block 121 when it is initially lowered, causing the shock wave of the initial impact to be weak, affecting the signal collection of the shallow stratum;

[0119] Secondly, when the rebounding force of the inclined spring block 213 is released, the inclined spring block 213 is reset, and the piston plate one 212 is reset when the hammering block 121 rebounds, and the hydraulic oil one is extruded into the special-shaped groove 215 again, at this time, the hydraulic oil one naturally flows along the main channel of the special-shaped groove 215, and the branch area has small resistance to the main channel, at the same time, the gas in the hydraulic groove 211 is extruded by the piston plate two 222, so that the gas is high pressure, and at the same time, the right side of the piston plate two 222 forms a negative pressure, which generates a traction force on the piston plate two 222, which accelerates the reset speed of the piston plate two 222, so that the inclined spring block 213 is quickly reset to block the hammering block 121, effectively preventing the resistance of the hydraulic oil one in the hydraulic groove 211 from being too large, which will cause the reset speed of the inclined spring block 213 to be slow, and the rebounding speed of the hammering block 121 after hitting the ground to be fast, and the inclined spring block 213 is difficult to block the hammering block 121 in time.
