Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seismic exploration equipment, in particular to a shallow layer seismic exploration equipment and a using method thereof. BACKGROUND

[0002] The shallow layer seismic exploration is mainly used for detecting the geological structure in the depth range of hundreds of meters below the ground surface, and is widely applied in the fields of engineering geological investigation, mineral resource investigation, underground water searching and geological disaster assessment, etc. The shallow layer seismic exploration mainly excites seismic waves and receives the seismic waves reflected or refracted from different rock layer interfaces, and analyzes the propagation time, amplitude, frequency and other characteristics of the waves to infer the geological structure underground, and is widely applied in coal field and engineering geological exploration, regional geological research and crust research.

[0003] In the seismic exploration, the drop hammer method is often used to excite the seismic source to explore the shallow layer. When the drop hammer hits the ground, a strong impact force is generated on the ground. When the hit ground is hard, the impact force may cause the drop hammer to rebound, resulting in a too high rebound height of the drop hammer, which hits the ground again, interferes with the seismic wave formed by the initial impact, confuses the effective reflection signal, and affects the accuracy of the exploration. SUMMARY

[0004] To solve the above technical problems, the present application provides a shallow layer seismic exploration equipment, which comprises a frame, two chain wheel rods rotatably connected to the inner wall of the frame, a motor fixedly connected to the back of the frame, and an output end of the motor fixedly connected to the side wall of the bottom chain wheel rod; a frame mechanism, a driving assembly rotatably arranged at the inner wall of the frame mechanism, an impact assembly installed at the side wall of the frame mechanism, and the driving assembly for providing the power of the weight hitting the ground; a buffer mechanism installed at the inner wall of the frame mechanism for reducing the rebound height of the weight after hitting the ground; and a speed reduction assembly located at the inner wall of the frame mechanism for reducing the speed of the weight after rebounding and descending again; a hydraulic groove is formed in the inner wall of the frame, a piston plate one is slidably connected to the inner wall of the hydraulic groove, a beveled spring block is fixedly connected to the side wall of the piston plate one, the outer wall of the beveled spring block is slidably connected to the inner wall of the frame, and a sealing rubber strip one is fixedly connected to the outer wall of the piston plate one; Among them, when it is necessary to hit the ground to generate shock waves, the frame mechanism is used to make the heavy object fall from a high place and hit the ground quickly to generate shock waves. The buffer mechanism is used to reduce the rebound height of the heavy object, effectively preventing the heavy object from rebounding to a high height, generating a strong impact force, and hitting the ground again, interfering with the shock waves formed by the initial impact. Finally, the deceleration component is used to reduce the speed at which the heavy object falls again after rebounding, effectively preventing the heavy object from falling again at a fast speed after rebounding, which will form multiple small rebounds and multiple shock waves.

[0005] Preferably, the framework mechanism comprises: A driving assembly is rotatably arranged at an outer wall of the driving assembly and an inner wall of the frame, and is used to lift the height of the heavy object; An impact assembly, wherein the inner wall of the impact assembly is slidably arranged with the side wall of the frame, and is used to drop the heavy object; Among them, when it is necessary to generate shock waves on the ground, the heavy object is lifted up by the driving component. When the heavy object rises to the right position, the impact component is used to make the heavy object fall and hit the ground, generating shock waves.

[0006] Preferably, the buffer mechanism comprises: A blocking assembly is slidably disposed on the inner wall of the frame and is used to reduce the rebound height of the heavy object; A clamping assembly is slidably arranged on the inner wall of the frame through a sliding member, and is used to clamp the blocking assembly to block the blocking assembly; The sliding member includes an air pressure groove provided on the inner wall of the frame, a piston plate 2 is slidably connected to the inner wall of the air pressure groove, and a sealing rubber strip 2 is fixedly connected to the outer wall of the piston plate 2 to ensure that the gas will not leak when the piston plate 2 squeezes the gas; Among them, when the driving component lifts the heavy object, it will squeeze the blocking component to move and clamp the blocking component through the clamping component. When the heavy object drops, the clamping component will separate from the blocking component, allowing the blocking component to reset, blocking the rebounding heavy object and reducing the rebound height of the heavy object. It effectively prevents the heavy object from rebounding to a high height, generating a strong impact force, hitting the ground again, and interfering with the shock wave formed by the initial impact, ensuring accurate reflection signals, and ensuring the accuracy of exploration.

[0007] Preferably, the deceleration assembly comprises: An extrusion assembly is slidably arranged on the inner wall of the frame through a connecting piece and is used to squeeze heavy objects; The connecting member includes two spring pressure plates slidably connected to the inner wall of the frame, and the inner wall of the frame is slidably connected to two push plates; A reset assembly is slidably arranged on the inner wall of the frame and is used to return the extrusion assembly to its original position; Among them, when the heavy object rebounds and squeezes the blocking component again, the blocking component will squeeze the extrusion component out, squeeze the heavy object, increase the descending resistance of the heavy object, and effectively prevent the heavy object from rebounding and falling again at a faster speed. After hitting the ground, it will form multiple small rebounds and multiple shock waves, which will interfere with the accurate reception of exploration signals. The reset component will keep the extrusion component in place when the heavy object falls from a high place for the first time.

[0008] Preferably, the drive assembly includes two chains arranged on the side walls of the frame, and the inner walls of the two chains are meshed and connected with the outer walls of the two sprocket rods; The impact assembly includes a hammer block slidably connected to the side wall of the frame, and two jacking blocks are fixedly connected to the front and back of the two chains; Among them, when it is necessary to hit the ground to generate shock waves, the starting motor drives the sprocket rod to rotate, so that the chain rotates, and the chain drives the lifting block at the bottom to rise. The lifting block at the bottom will contact the protruding position of the hammer block, and the lifting block will lift the hammer block to make the hammer block rise. As the chain continues to rotate, the lifting block will move to the position of the sprocket rod at the top. The chain continues to rotate, which will drive the lifting block to separate from the hammer block. At this time, the thrust on the hammer block disappears. Since the hammer block is heavy, it is affected by its own weight and will drop rapidly, hitting the ground and generating shock waves.

[0009] Preferably, the blocking assembly includes a snap-fit ​​block slidably connected to the inner wall of the hydraulic groove, the side wall of the snap-fit ​​block is fixedly connected to the side wall of the piston plate 1, a special-shaped groove is opened on the inner wall of the frame, hydraulic oil 1 is provided on the inner wall of the hydraulic groove, and a sealing ring 1 is installed at the sliding position of the inclined spring block and the frame to prevent leakage of the hydraulic oil 1 in the hydraulic groove; Among them, when the hammer block rises for the first time, the inclined surface of the hammer block will squeeze the inclined surface of the inclined spring block, causing the inclined spring block to move toward the piston plate and at the same time accumulate rebound force.

[0010] Preferably, the clamping assembly includes an extrusion rod fixedly connected to the top of the hammer block, the side wall of the piston plate 1 is fixedly connected to the side wall of the clamping block, and a fixing frame is fixedly connected to the side of the frame close to the hammer block; A rocker is rotatably connected to the outer wall of the fixed frame, a spring clamping rod is slidably connected to the inner wall of the frame, and a second sealing ring is fixedly connected to the inner wall of the frame; As the hammer block continues to rise, the inclined spring block will separate from the hammer block, and since the spring clamping rod is inserted into the clamping block, it will limit the return of the inclined spring block. When the hammer block falls and hits the ground, the extrusion rod will contact the seesaw again, pushing the seesaw to rotate, causing the side of the seesaw in contact with the extrusion rod to fall and the other side to rise. The rising side will push the spring clamping rod to rise, putting the spring clamping rod in a compressed state, causing the spring clamping rod to separate from the clamping block. At this time, the rebound force of the inclined spring block will be released, causing it to return to its original position. When the hammer block hits the ground and rebounds, the hammer block will squeeze the inclined spring block again, allowing the piston plate to move, and drive the piston plate two to move through the clamping block. When the piston plate one moves, it will squeeze the hydraulic oil one in the hydraulic groove, enter the special-shaped groove, and enter the right side of the piston plate one through the special-shaped groove. Because the special-shaped groove has multiple complex flow channels, the hydraulic oil one will be forced to divert by the asymmetric branch in the special-shaped groove, which will change the flow path of the hydraulic oil one and cause multiple hydraulic oils to collide, which will slow down the flow speed of the hydraulic oil one, thereby slowing down the movement speed of the piston plate one; At the same time, when the piston plate 2 moves, it will squeeze the gas on the left side of the piston plate 2, causing the gas on the left side to generate high pressure. At the same time, the space on the right side of the piston plate 2 will increase, causing negative pressure on the right side of the piston plate 2, generating attraction to the piston plate 2. Through the sealing ring 2, the hydraulic oil 1 in the hydraulic groove is prevented from being attracted by the negative pressure in the air pressure groove and entering the air pressure groove, generating high pressure through the left side of the piston plate 2 and negative pressure on the right side, increasing the movement resistance of the piston plate 2. At the same time, the movement speed of the piston plate 1 is slowed down, making the movement resistance of the inclined spring block stronger, which will block the hammer block from rising and reduce the rebound height of the hammer block, effectively preventing the hammer block from rebounding to a high height, generating a strong impact force, hitting the ground again, interfering with the shock wave formed by the initial impact, ensuring accurate reflection signal, and ensuring the accuracy of exploration.

[0011] Preferably, the extrusion assembly includes connecting rods 1 provided on the front and back of the frame, the inner walls of the two connecting rods 1 are slidably connected to the side walls of the two push plates, and the inner walls of the two push plates are slidably connected to the outer walls of the two spring pressure plates; The side walls of the inclined spring block are fixedly connected to two connecting rods 2, the side walls of the two connecting rods 2 are rotatably connected to connecting rods, and the inner walls of the two connecting rods are rotatably connected to the side walls of the two connecting rods 1; Two hydraulic cylinders are fixedly connected to the inner wall of the frame, piston rods are slidably connected to the inner walls of the two hydraulic cylinders, and the side walls of the two piston rods are fixedly connected to the side walls of the two push plates; The inner walls of the two piston rods are provided with communicating holes, and the inner walls of the two hydraulic cylinders are provided with hydraulic oil 2; Among them, when the inclined spring block moves toward the direction of the piston plate, it will drive the connecting rod two to move, and the connecting rod two will drive the connecting rod to rotate, pulling the connecting rod one to move toward the direction of the spring pressure plate, and the connecting rod one will squeeze the push plate to move, allowing the push plate to squeeze the spring on the spring pressure plate, so that the spring pressure plate accumulates rebound force, and the spring pressure plate squeezes the hammer block. The squeezing of the hammer block by the spring pressure plate will increase the descending resistance of the hammer block, slow down the descending speed of the hammer block, and make the hammer block slowly contact with the ground, effectively preventing the hammer block from rebounding and then descending faster again. After hitting the ground, it will form multiple small rebounds, forming multiple shock waves, which interfere with the accurate reception of exploration signals.

[0012] Preferably, the reset assembly includes two push rods slidably connected to the inner wall of the frame, and the side walls of the two push rods are fixedly connected to the sides of the two spring pressure plates away from the hammer block; Two arc-shaped inclined panels are slidably connected to the inner wall of the frame, and the side walls of the two arc-shaped inclined panels are fixedly connected to the side walls of the two push rods. The side walls of the four lifting blocks on the front and back are fixedly connected to ball-head push rods. Among them, when the hammer block is lifted up by the jacking block, it will squeeze the inclined spring block to move, and the inclined spring block will make the spring pressure plate squeeze the hammer block through the extrusion component. As the hammer block continues to rise, the hammer block will separate from the spring pressure plate. At this time, the rebound force of the spring pressure plate will be released, pushing the spring pressure plate toward the inclined spring block, driving the push rod to move, pushing the arc-shaped inclined plate to move, and making the arc-shaped inclined plate close to the chain. When the jacking block rises, it will also drive the ball push rod to rise. As the ball push rod continues to rise, the ball push rod will contact the inclined surface of the arc-shaped inclined plate. The arc-shaped inclined plate is squeezed to move away from the jacking block, driving the push rod and the spring pressure plate to move, so that the spring pressure plate is in a compressed state again. When the jacking block is separated from the hammer block, the ball head push rod will continue to squeeze the arc-shaped inclined plate. By making the spring pressure plate in a compressed state again, the spring pressure plate will not contact the hammer block when the hammer block first descends, effectively preventing the spring pressure plate from squeezing the hammer block when the hammer block first descends, slowing down the falling speed of the hammer block, reducing the impact force of the hammer block when it first descends, causing the shock wave of the first impact to be weaker, affecting the signal acquisition of shallow strata.

[0013] A method for using shallow seismic exploration equipment includes the following steps: S1: Starting the equipment: The operator moves the frame to the location where seismic exploration is required. After moving to the location, when the hammer block needs to hit the ground, the sprocket rod is driven by the starting motor to rotate, causing the chain to rotate; S2: The heavy object rises: The chain drives the lifting block at the bottom to rise. The lifting block at the bottom will contact the protruding position of the hammer block, and the lifting block will lift the hammer block, causing the hammer block to rise. As the chain continues to rotate, the lifting block will move to the position of the sprocket rod at the top; S3: Shock wave formation: As the chain continues to rotate, it will drive the lifting block and the hammer block to separate. At this time, the thrust on the hammer block disappears. Since the hammer block is heavy, it will fall rapidly under the influence of its own weight, hitting the ground and generating shock waves. Afterwards, the shock wave is explored.

[0014] The present invention has the following beneficial effects: (1) When the present invention is used, when it is necessary to make the hammer block hit the ground, the chain is driven to rotate by starting the motor, the hammer block is raised by the jacking block, and the hammer block is quickly lowered by the driving assembly to hit the ground and generate shock waves. When the hammer block first rises, the hammer block will squeeze the inclined spring block to move, and the spring clamping rod is inserted into the clamping block through the clamping assembly, which will limit the inclined spring block from returning to its original position. When the hammer block falls and hits the ground, the spring clamping rod is separated from the clamping block through the clamping assembly, allowing the inclined spring block to block the hammer block. When the hammer block hits the ground and rebounds, it will squeeze the inclined spring block again, and the hydraulic oil will be squeezed by the blocking assembly and the gas will be squeezed by the clamping assembly, which will increase the moving resistance of the inclined spring block. It will block the hammer block from rising and reduce the rebound height of the hammer block, effectively preventing the hammer block from rebounding to a high height and generating a strong impact force, hitting the ground again, and interfering with the shock wave formed by the initial impact, ensuring accurate reflection signals and ensuring the accuracy of exploration.

[0015] (2) In the present invention, when the inclined spring block moves toward the piston plate one, it will drive the connecting rod two to move. By rotating the connecting rod, the connecting rod one is pulled toward the spring pressure plate, which will squeeze the push plate to move, so that the push plate squeezes the spring on the spring pressure plate, and the spring pressure plate squeezes the hammer block. The spring pressure plate squeezes the hammer block, which increases the downward resistance of the hammer block, slows down the descending speed of the hammer block, and makes the hammer block slowly contact with the ground, effectively preventing the hammer block from rebounding and then falling again at a faster speed. After hitting the ground, it will form multiple small rebounds, forming multiple shock waves, which interfere with the accurate reception of the exploration signal.

[0016] (3) When the hammer block is lifted up by the lifting block, the present invention squeezes the inclined spring block to move. Through the squeezing assembly, the spring pressure plate squeezes the hammer block. As the hammer block continues to rise, the hammer block will separate from the spring pressure plate. At this time, the rebound force of the spring pressure plate will be released, allowing the spring pressure plate to drive the push rod and the arc-shaped inclined plate to move. When the lifting block rises, it will also drive the ball head push rod to rise. As the ball head push rod continues to rise, the ball head push rod will squeeze the arc-shaped inclined plate, driving the push rod and the spring pressure plate to move, so that when the hammer block first descends, the spring pressure plate will not contact the hammer block, effectively preventing the spring pressure plate from squeezing the hammer block when the hammer block first descends, slowing down the falling speed of the hammer block, reducing the impact force of the hammer block when it first descends, causing the shock wave of the first impact to be weak, affecting the signal collection of shallow strata.

[0017] (4) When the rebound force of the inclined spring block is released and it returns to its original position to block the rebound of the hammer block, the present invention will drive the piston plate 1 to return to its original position and squeeze the hydraulic oil 1 into the special-shaped groove again. At this time, the hydraulic oil 1 will naturally flow along the main channel of the special-shaped groove, and the branch area will have less obstruction to the main channel. At the same time, the gas in the hydraulic groove is squeezed by the piston plate 2, so that the gas generates high pressure. At the same time, negative pressure is formed on the right side of the piston plate 2, which generates traction on the piston plate 2 and accelerates the return speed of the piston plate 2, thereby making the inclined spring block return quickly and blocking the hammer block, effectively preventing the hydraulic oil 1 in the hydraulic groove from having a large resistance, which will cause the return speed of the inclined spring block to slow down, and the hammer block will rebound quickly when it hits the ground, making it difficult for the inclined spring block to block the hammer block in time.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0022] Example one, please refer to Figure 1 - Figure 6The application discloses a shallow seismic exploration equipment, which comprises a frame 111, two chain wheel rods 112 are rotationally connected to the inner wall of the frame 111, a motor 113 is fixedly connected to the back of the frame 111, and the output end of the side wall of the motor 113 is fixedly connected to the side wall of the bottom chain wheel rod 112. The frame mechanism 1 is provided with the driving assembly 11 rotationally arranged at the inner wall of the frame mechanism 1 and the impact assembly 12 installed at the side wall of the frame mechanism 1, and the driving assembly 11 is used for providing the power for the heavy object to impact the ground. The buffer mechanism 2 is installed at the inner wall of the frame mechanism 1 and is used for reducing the rebound height of the heavy object after the heavy object impacts the ground. The speed reduction assembly 3 is located at the inner wall of the frame mechanism 1 and is used for reducing the speed of the heavy object after the heavy object rebounds. The hydraulic groove 211 is formed in the inner wall of the frame 111, the piston plate one 212 is slidably connected to the inner wall of the hydraulic groove 211, the inclined spring block 213 is fixedly connected to the side wall of the piston plate one 212, the outer wall of the inclined spring block 213 is slidably connected to the inner wall of the frame 111, and the outer wall of the piston plate one 212 is fixedly connected with the sealing rubber strip one. When the ground needs to be impacted to generate seismic waves, the heavy object is caused to fall from a high place and quickly impact the ground through the frame mechanism 1 to generate seismic waves, the rebound height of the heavy object is reduced through the buffer mechanism 2, the rebound height of the heavy object is effectively prevented from being too high to generate a strong impact force, the heavy object is caused to impact the ground again to interfere with the seismic waves formed by the first impact, finally, the speed of the heavy object after rebounding is reduced through the speed reduction assembly 3, and the speed of the heavy object after rebounding is effectively prevented from being too fast to form multiple small-amplitude rebounds and multiple seismic waves.

[0023] The frame mechanism 1 comprises: The driving assembly 11 is rotationally arranged at the inner wall of the frame 111 and is used for lifting the height of the heavy object. The impact assembly 12 is slidably arranged at the side wall of the frame 111 and is used for causing the heavy object to fall. When the ground needs to be impacted to generate seismic waves, the heavy object is lifted through the driving assembly 11, the heavy object is caused to fall and impact the ground through the impact assembly 12 after the heavy object is lifted to a position, and seismic waves are generated.

[0024] The buffer mechanism 2 comprises: The blocking assembly 21 is slidably arranged at the inner wall of the frame 111 and is used for reducing the rebound height of the heavy object. The clamping assembly 22 is slidably arranged at the inner wall of the frame 111 through a sliding piece and is used for clamping and blocking the blocking assembly 21. The sliding member includes an air pressure groove 221 formed on the inner wall of the vehicle frame 111. A second piston plate 222 is slidably connected to the inner wall of the air pressure groove 221. A second sealing rubber strip is fixedly connected to the outer wall of the second piston plate 222 to ensure that the gas does not leak when the second piston plate 222 squeezes the gas. Among them, when the driving component 11 lifts the heavy object, it will squeeze the blocking component 21 to move, and the blocking component 21 will be clamped by the clamping component 22. When the heavy object drops, the clamping component 22 will separate from the blocking component 21, allowing the blocking component 21 to reset, blocking the rebounding heavy object, reducing the rebound height of the heavy object, and effectively preventing the heavy object from rebounding to a high height, generating a strong impact force, hitting the ground again, interfering with the shock wave formed by the initial impact, ensuring accurate reflection signals, and ensuring the accuracy of exploration.

After hitting the ground, it will form multiple small rebounds and multiple shock waves, which will interfere with the accurate reception of the exploration signal. Through the reset component 32, the squeezing component 31 will be in place when the heavy object falls from a high place for the first time.

[0026] For example 2, please refer to Figure 1 - Figure 14 The present invention is a shallow seismic exploration device. Based on the first embodiment, the driving assembly 11 includes two chains 114 provided on the side walls of the frame 111. The inner walls of the two chains 114 are meshed and connected with the outer walls of the two sprocket rods 112. The impact assembly 12 includes a hammer block 121 slidably connected to the side wall of the frame 111 , and two lifting blocks 122 are fixedly connected to the front and back of the two chains 114 ; When the ground needs to be struck to generate shock waves, the starting motor 113 drives the sprocket rod 112 to rotate, so that the chain 114 rotates, and the chain 114 drives the lifting block 122 at the bottom to rise, and the lifting block 122 at the bottom will contact the protruding position of the hammer block 121, such as Figure 4As shown in the position of G in the middle, 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 drive the lifting block 122 to separate from the hammer block 121. At this time, the thrust on the hammer block 121 disappears. Since the hammer block 121 is heavier, it is affected by its own weight and the hammer block 121 will drop rapidly, hitting the ground and generating shock waves.

[0027] The blocking assembly 21 includes a snap-fit ​​block 214 slidably connected to the inner wall of the hydraulic groove 211. The side wall of the snap-fit ​​block 214 is fixedly connected to the side wall of the piston plate 1 212. A special-shaped groove 215 is formed on the inner wall of the frame 111. Hydraulic oil 1 is provided on the inner wall of the hydraulic groove 211. A sealing ring 1 is installed at the sliding position between the inclined spring block 213 and the frame 111 to prevent leakage of the hydraulic oil 1 in the hydraulic groove 211. When the hammer block 121 first rises, the inclined surface of the hammer block 121 will press the inclined surface of the inclined spring block 213, causing the inclined spring block 213 to move toward the piston plate 1 212, while accumulating rebound force.

[0028] The clamping assembly 22 includes an extrusion rod 223 fixedly connected to the top of the hammer block 121, the side wall of the piston plate 212 is fixedly connected to the side wall of the clamping block 214, and a fixing bracket 224 is fixedly connected to the side of the frame 111 near the hammer block 121; The outer wall of the fixing frame 224 is rotatably connected to a rocker plate 225, the inner wall of the frame 111 is slidably connected to a spring clamping rod 226, and the inner wall of the frame 111 is fixedly connected to a sealing ring 2. Figure 6 As shown in the position of H in the middle; The hammer block 121 will also drive the extrusion rod 223 to rise, so that the extrusion rod 223 and the rocker plate 225 are separated. At this time, the thrust on the spring clamping rod 226 disappears. Since the spring clamping rod 226 was in a compressed state before, the rebound force of the spring clamping rod 226 is released, so that it returns to its original position. When the inclined spring block 213 moves, it will also drive the piston plate 1 212 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 squeeze the inclined surface of the spring clamping rod 226, pushing the spring clamping rod 226 up and accumulating rebound force. As the locking block 214 continues to move, when the notch inside the locking block 214 is aligned with the spring clamping rod 226, as shown in FIG. Figure 7In the state shown in center I, the resilience of the spring clamping rod 226 is released, allowing the spring clamping rod 226 to be inserted into the notch. At this time, the inclined surface of the hammer block 121 is separated from the inclined surface of the inclined spring block 213, and the squeezing force on the inclined spring block 213 disappears. As the hammer block 121 continues to rise, the inclined spring block 213 is separated from the hammer block 121. Since the spring clamping rod 226 is inserted into the engaging block 214, it restricts the inclined spring block 213 from returning to its original position. When the hammer block 121 falls and hits the ground, the extrusion rod 223 will contact the rocker 225 again, pushing the rocker 225 to rotate, so that the side of the rocker 225 in contact with the extrusion rod 223 falls and the other side rises. The rising side will push the spring clamping rod 226 to rise, so that the spring clamping rod 226 is in a compressed state, so that the spring clamping rod 226 is separated from the locking block 214. At this time, the rebound force of the inclined spring block 213 will be released, so that it returns to its original position. When the hammer block 121 hits the ground and rebounds, the hammer block 121 will squeeze the inclined spring block 213 again. 3. Move the piston plate 1 212, and drive the piston plate 2 22 to move via the engaging block 214. When the piston plate 1 212 moves, it squeezes the hydraulic oil 1 in the hydraulic groove 211, enters the special-shaped groove 215, and then enters the right side of the piston plate 1 212 through the special-shaped groove 215. Since the special-shaped groove 215 has multiple complex flow channels, the hydraulic oil 1 will be forced to be diverted by the asymmetric branches in the special-shaped groove 215, which will change the flow path of the hydraulic oil 1, causing multiple hydraulic oil 1 streams to collide, slowing down the flow speed of the hydraulic oil 1, and thus slowing down the movement speed of the piston plate 1 212; At the same time, when the piston plate 222 moves, the gas on the left side of the piston plate 222 will be squeezed, so that the gas on the left side will generate high pressure. At the same time, the space on the right side of the piston plate 222 will be expanded, so that the right side of the piston plate 222 will generate negative pressure, which will generate attraction to the piston plate 222. Figure 6 The sealing ring 2 in the hydraulic groove 211 prevents the hydraulic oil 1 from being attracted by the negative pressure in the air pressure groove 221 and entering the air pressure groove 221, generating high pressure on the left side of the piston plate 222 and negative pressure on the right side, thereby increasing the movement resistance of the piston plate 222. At the same time, the movement speed of the piston plate 1 212 is slowed down, so that the movement resistance of the inclined spring block 213 is stronger, which will block the hammer block 121 from rising and reduce the rebound height of the hammer block 121, effectively preventing the hammer block 121 from rebounding to a high height, generating a strong impact force, and hitting the ground again, interfering with the shock wave formed by the initial impact, ensuring accurate reflection signals, and ensuring the accuracy of exploration.

[0029] The extrusion assembly 31 includes connecting rods 313 provided on the front and back of the vehicle frame 111. The inner walls of the two connecting rods 313 are slidably connected to the side walls of the two push plates 312. The inner walls of the two push plates 312 are slidably connected to the outer walls of the two spring pressure plates 311. The side walls of the inclined spring block 213 are fixedly connected to two connecting rods 314, the side walls of the two connecting rods 314 are rotatably connected to connecting rods 315, and the inner walls of the two connecting rods 315 are rotatably connected to the side walls of the two connecting rods 313; Two hydraulic cylinders 316 are fixedly connected to the inner wall of the vehicle frame 111. Piston rods 317 are slidably connected to the inner walls of the two hydraulic cylinders 316. The side walls of the two piston rods 317 are fixedly connected to the side walls of the two push plates 312. The inner walls of the two piston rods 317 are provided with a communication hole 318, and the inner walls of the two hydraulic cylinders 316 are provided with hydraulic oil 2; Among them, when the inclined spring block 213 moves toward the piston plate 1 212, it will drive the connecting rod 2 314 to move, and the connecting rod 2 314 will drive the connecting rod 315 to rotate, pulling the connecting rod 1 313 to move toward the spring pressure plate 311, and the connecting rod 1 313 will squeeze the push plate 312 to move, allowing the push plate 312 to squeeze the spring on the spring pressure plate 311, so that the spring pressure plate 311 accumulates rebound force, allowing the spring pressure plate 311 to squeeze the hammer block 121. The squeezing of the hammer block 121 by the spring pressure plate 311 will increase the descending resistance of the hammer block 121, slowing down the descending speed of the hammer block 121, and making the hammer block 121 slowly contact the ground, effectively preventing the hammer block 121 from rebounding and then descending again at a faster speed. After hitting the ground, multiple small rebounds will be formed, forming multiple shock waves, which will interfere with the accurate reception of the exploration signal.

[0030] The reset assembly 32 includes two push rods 321 slidably connected to the inner wall of the frame 111 , and 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 ; Two arc-shaped inclined panels 322 are slidably connected to the inner wall of the frame 111. The side walls of the two arc-shaped inclined panels 322 are fixedly connected to the side walls of the two push rods 321. The side walls of the four lifting blocks 122 on the front and back are fixedly connected to the ball head push rods 323. When the lifting block 121 is lifted up by the lifting block 122, the inclined spring block 213 will be squeezed to move. The inclined spring block 213 will cause the spring pressure plate 311 to squeeze the hammer block 121 through the squeezing assembly 31. As the hammer block 121 continues to rise, the hammer block 121 will separate from the spring pressure plate 311. At this time, the resilience of the spring pressure plate 311 will be released, pushing the spring pressure plate 311 to move toward the inclined spring block 213, driving the push rod 321 to move, pushing the arc-shaped inclined plate 322 to move, so that the arc-shaped inclined plate 322 is close to the chain 114. When the lifting block 122 rises, it will also drive the ball head push rod 323 to rise. As the ball head push rod 323 continues to rise, the ball head push rod 323 will contact the inclined surface of the arc-shaped inclined plate 322, squeezing the arc-shaped inclined plate 322, making it away from the lifting block 122. Figure 12 As shown, the push rod 321 and the spring pressure plate 311 are driven to move, so that the spring pressure plate 311 is in a compressed state again. When the lifting block 122 is separated from the hammer block 121, the ball head push rod 323 will continue to squeeze the arc-shaped inclined plate 322. By making the spring pressure plate 311 in a compressed state again, the spring pressure plate 311 will not contact the hammer block 121 when the hammer block 121 first descends, effectively preventing the spring pressure plate 311 from squeezing the hammer block 121 when the hammer block 121 first descends, slowing down the falling speed of the hammer block 121, and reducing the impact force of the hammer block 121 when it first descends, causing the shock wave of the first impact to be weak, affecting the signal collection of shallow strata.

[0032] The method for using the shallow seismic exploration equipment includes the following steps: S1: Starting the equipment: The operator moves the frame 111 to the location where seismic exploration is required. After moving to the location, when it is necessary to make the hammer block 121 hit the ground, the sprocket rod 112 is driven to rotate by the starting motor 113, so that the chain 114 rotates; S2: The weight rises: The chain 114 drives the lifting block 122 at the bottom to rise. The lifting block 122 at the bottom contacts the protruding portion of the hammer block 121, and the lifting block 122 lifts the hammer block 121, causing the hammer block 121 to rise. As the chain 114 continues to rotate, the lifting block 122 moves to the position of the sprocket rod 112 at the top. S3: Shock wave formation: The chain 114 continues to rotate, which will drive the lifting block 122 to separate from the hammer block 121. At this time, the thrust on the hammer block 121 disappears. Since the hammer block 121 is heavy, it will fall rapidly under the influence of its own weight and hit the ground, generating a shock wave. Afterwards, the shock wave is explored.

[0033] A specific application of this embodiment is as follows: when the present invention is used, the operator moves the vehicle frame 111 to a location where seismic exploration is required. After the vehicle frame 111 is in position, when the hammer block 121 needs to hit the ground, the sprocket rod 112 is driven to rotate by starting the motor 113, so that the chain 114 rotates, and the chain 114 drives the lifting block 122 at the bottom to rise. The lifting block 122 at the bottom will contact the protruding position of the hammer block 121, such as Figure 4 As shown in the position of G in the middle, 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 drive the lifting block 122 to separate from the hammer block 121. At this time, the thrust on the hammer block 121 disappears. Since the hammer block 121 is heavy, it will fall rapidly under the influence of its own weight and hit the ground, generating shock waves. Afterwards, the shock waves are explored; Among them, when the hammer block 121 rises for the first time, the inclined surface of the hammer block 121 will squeeze the inclined surface of the inclined spring block 213, so that the inclined spring block 213 moves toward the piston plate 212. At the same time, the rebound force is accumulated, and the hammer block 121 will also drive the extrusion rod 223 to rise, so that the extrusion rod 223 is separated from the rocker 225. At this time, the thrust on the spring clamping rod 226 disappears. Since the spring clamping rod 226 is in a compressed state before, the spring clamping rod 226 is in a compressed state. The rebound force of the connecting rod 226 will be released, causing it to return to its original position. When the inclined spring block 213 moves, it will also drive the piston plate 1 212 and the engaging block 214 to move synchronously. As the engaging block 214 continues to move, the inclined surface of the engaging block 214 will squeeze the inclined surface of the spring engaging rod 226, pushing up the spring engaging rod 226 and accumulating rebound force. As the engaging block 214 continues to move, when the notch inside the engaging block 214 is aligned with the spring engaging rod 226, as shown in FIG. Figure 7 In the state shown in center I, the resilience of the spring clamping rod 226 is released, allowing the spring clamping rod 226 to be inserted into the notch. At this time, the inclined surface of the hammer block 121 is separated from the inclined surface of the inclined spring block 213, and the squeezing force on the inclined spring block 213 disappears. As the hammer block 121 continues to rise, the inclined spring block 213 is separated from the hammer block 121. Since the spring clamping rod 226 is inserted into the engaging block 214, it restricts the inclined spring block 213 from returning to its original position. When the hammer block 121 falls and hits the ground, the extrusion rod 223 will contact the rocker 225 again, pushing the rocker 225 to rotate, so that the side of the rocker 225 in contact with the extrusion rod 223 falls and the other side rises. The rising side will push the spring clamping rod 226 to rise, so that the spring clamping rod 226 is in a compressed state, so that the spring clamping rod 226 is separated from the locking block 214. At this time, the rebound force of the inclined spring block 213 will be released, so that it returns to its original position. When the hammer block 121 hits the ground and rebounds, the hammer block 121 will squeeze the inclined spring block 213 again. 3. Move the piston plate 1 212, and drive the piston plate 2 22 to move via the engaging block 214. When the piston plate 1 212 moves, it squeezes the hydraulic oil 1 in the hydraulic groove 211, enters the special-shaped groove 215, and then enters the right side of the piston plate 1 212 through the special-shaped groove 215. Since the special-shaped groove 215 has multiple complex flow channels, the hydraulic oil 1 will be forced to be diverted by the asymmetric branches in the special-shaped groove 215, which will change the flow path of the hydraulic oil 1, causing multiple hydraulic oil 1 streams to collide, slowing down the flow speed of the hydraulic oil 1, and thus slowing down the movement speed of the piston plate 1 212; At the same time, when the piston plate 222 moves, the gas on the left side of the piston plate 222 will be squeezed, so that the gas on the left side will generate high pressure. At the same time, the space on the right side of the piston plate 222 will be expanded, so that the right side of the piston plate 222 will generate negative pressure, which will generate attraction to the piston plate 222. 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 air pressure groove 221 and entering the air pressure groove 221, thereby generating high pressure on the left side of the second piston plate 222 and negative pressure on the right side, thereby increasing the movement resistance of the second piston plate 222 and slowing down the movement speed of the first piston plate 212, so that the movement resistance of the inclined spring block 213 is stronger, thereby blocking the hammer block 121 from rising and reducing the rebound height of the hammer block 121, effectively preventing the hammer block 121 from rebounding to a high height and generating a strong impact force, causing it to hit the ground again and interfere with the shock wave formed by the initial impact, thereby ensuring accurate reflection signals and ensuring the accuracy of exploration; Secondly, when the inclined spring block 213 moves toward the piston plate 1 212, it will drive the connecting rod 2 314 to move, and the connecting rod 2 314 will drive the connecting rod 315 to rotate, pulling the connecting rod 1 313 to move toward the spring pressure plate 311, and the connecting rod 1 313 will squeeze the push plate 312 to move, so that the push plate 312 squeezes the spring on the spring pressure plate 311, so that the spring pressure plate 311 accumulates rebound force, and the spring pressure plate 311 squeezes the hammer block 121. The squeezing of the hammer block 121 by the spring pressure plate 311 will increase the downward resistance of the hammer block 121, slowing down the descending speed of the hammer block 121, and making the hammer block 121 slowly contact the ground, effectively preventing the hammer block 121 from rebounding and falling again at a faster speed. After hitting the ground, multiple small rebounds will be formed, forming multiple shock waves, which will interfere with the accurate reception of the exploration signal; When the push plate 312 squeezes the spring pressure plate 311, it drives the piston rod 317 to squeeze the hydraulic oil in the hydraulic cylinder 316, and flows to the left side of the piston rod 317 through the connecting hole 318. Figure 10 After the hammer block 121 rebounds, when it drops again, the rebound force of the inclined spring block 213 is released, allowing the second connecting rod 314 to return to its original position, and the first connecting rod 313 to return to its original position through the connecting rod 315. At this time, the squeezing force on the push plate 312 disappears, and the rebound force of the spring pressure plate 311 is released, which will push the push plate 312 to return to its original position, causing the piston rod 317 to squeeze the second hydraulic oil again and flow through the connecting hole 318. Since the connecting hole 318 is small in size, the flow resistance of the second hydraulic oil will be increased, thereby slowing down the return speed of the push plate 312, avoiding the hammer block 121 from separating from the inclined spring block 213, allowing the first connecting rod 313 to return quickly, causing the push plate 312 to return, and allowing the squeezing force of the spring pressure plate 311 on the hammer block 121 to be quickly reduced, affecting the squeezing of the hammer block 121; When the lifting block 122 is lifted up, the inclined spring block 213 will be squeezed to move. The inclined spring block 213 will make the spring pressure plate 311 squeeze the hammer block 121 through the squeezing assembly 31. As the hammer block 121 continues to rise, the hammer block 121 will separate from the spring pressure plate 311. At this time, the resilience of the spring pressure plate 311 will be released, pushing the spring pressure plate 311 toward the inclined spring block 213, driving the push rod 321 to move, pushing the arc-shaped inclined plate 322 to move, so that the arc-shaped inclined plate 322 is close to the chain 114. When the lifting block 122 rises, it will also drive the ball head push rod 323 to rise. As the ball head push rod 323 continues to rise, the ball head push rod 323 will contact the inclined surface of the arc-shaped inclined plate 322, squeezing the arc-shaped inclined plate 322, making it away from the lifting block 122. Figure 12 As shown, the push rod 321 and the spring pressure plate 311 are driven to move, so that the spring pressure plate 311 is in a compressed state again. When the lifting block 122 is separated from the hammer block 121, the ball head push rod 323 will continue to squeeze the arc-shaped inclined plate 322. By making the spring pressure plate 311 in a compressed state again, the spring pressure plate 311 will not contact the hammer block 121 when the hammer block 121 first descends, effectively preventing the spring pressure plate 311 from squeezing the hammer block 121 when the hammer block 121 first descends, slowing down the falling speed of the hammer block 121, and reducing the impact force of the hammer block 121 when it first descends, resulting in a weaker shock wave of the first impact, which affects the signal acquisition of shallow formations. Secondly, when the rebound force of the inclined spring block 213 is released and it returns to its original position, blocking the hammer block 121 from rebounding, it will drive the piston plate 1 212 to return and squeeze the hydraulic oil 1 into the special-shaped groove 215 again. At this time, the hydraulic oil 1 will naturally flow along the main channel of the special-shaped groove 215, and the branch area will have less obstruction to the main channel. At the same time, the gas in the hydraulic groove 211 is squeezed by the piston plate 222, so that the gas generates high pressure. At the same time, negative pressure is formed on the right side of the piston plate 222, which generates traction on the piston plate 222, which will accelerate the return speed of the piston plate 222, thereby making the inclined spring block 213 return quickly and block the hammer block 121, effectively preventing the hydraulic oil 1 in the hydraulic groove 211 from having a large resistance, which will cause the inclined spring block 213 to return slowly, and the hammer block 121 hits the ground and rebounds quickly, making it difficult for the inclined spring block 213 to block the hammer block 121 in time.

A method for using shallow seismic exploration equipment, using the shallow seismic exploration equipment according to claim 9, characterized in that: The following steps are included: S1: Starting the equipment: The operator moves the vehicle frame (111) to the location where seismic exploration is required. After the vehicle frame (111) is moved to the location, when the hammer block (121) needs to hit the ground, the sprocket rod (112) is driven to rotate by the starting motor (113), thereby rotating the chain (114); S2: The weight rises: the chain (114) drives the lifting block (122) at the bottom to rise, and the lifting block (122) at the bottom contacts the protruding position of the hammer block (121), and the lifting block (122) lifts the hammer block (121), so that the hammer block (121) rises. As the chain (114) continues to rotate, the lifting block (122) moves to the position of the sprocket rod (112) at the top; S3: Shock wave formation: The chain (114) continues to rotate, which drives the lifting block (122) to separate from the hammer block (121). At this time, the thrust on the hammer block (121) disappears. Since the hammer block (121) is heavy, it is affected by its own weight and the hammer block (121) will drop rapidly and hit the ground, generating a shock wave. Afterwards, the shock wave is explored.
