[0020] Optionally, the method for using the bursting funnel test experimental device comprises the following steps:

[0021] S1. First, take out the stone samples that need to be blasted, and regularize the samples. Put the uniformly polished stones on the conveyor belt in the conveyor assembly. After the output shaft of the main push cylinder is started, it moves forward to push the stone into the channel on the U-shaped frame. The front end of the stone will push the rectangular block to move in the direction of the L-shaped splicing plate during the forward movement. Since the upper and lower ends of the special-shaped slider are in the trapezoidal slide, the special-shaped slider will move in a straight line in the trapezoidal slide. As the special-shaped slider moves, the toggle rack on the other side of the special-shaped slider begins to mesh with the side rack of the transmission toothed belt. At the same time, since the transmission toothed belt rotates, it will drive the internal linkage wheel to rotate together. At this time, the transmission gear under the side surface of the linkage wheel also rotates, and the three meshing connected with the transmission gear. The forward push rack begins to expand outward from the hole in the U-shaped frame, and the positioning plate located on the top of the forward push rack pulls the door plate and the positioning slider to move along the placement slide in the flat wing plate. The positioning threaded sleeve between the two door plates moves along the placement threaded rod, which will cause the placement threaded rod to rotate in the placement shaft plate. The rotating placement threaded rod causes the worm at the other end to rotate the large worm gear and the transmission worm gear respectively, and the transmission worm gear will also drive the bevel gear to rotate when it rotates. When the two large worm gears and the bevel gears rotate, the connecting shaft rod and the arc sleeve will flip over, and the tilting plate will flip over together when flipping here. The stone will first be built on the upper surface between the two flat wing plates. At this time, the special-shaped slider will shrink inward along the trapezoidal slide ramp in the rectangular frame without affecting the movement of the stone.

[0022] S2. After the push plate passes through the rectangular block and resets, the two positioning sliders are repeatedly pulled together toward the middle, and the other end of the positioning plate slides on the side surface of the limit slider. After the special-shaped slider moves to the original position of the rectangular frame, after the push plate is continuously squeezed, the inclined surface of the rectangular block causes the special-shaped slider to squeeze the reset spring and move toward the limit slider, thereby keeping the two L-shaped splicing plates closed and clamping the stone, and keeping the stone on the top of the inclined plate;

[0023] S3. After the push plate is separated from the side surface of the U-shaped frame and the conveyor belt, the rear side of the push plate pushes the T push frame to move in the direction of the main push cylinder, wherein the stepping threaded rod at the bottom of the T push frame rotates inside the side surface of the stepping shaft plate, and the stepping rotating rod at the other end drives the middle shaft sleeve to rotate, wherein the groove shaft seat and the one-way paddle move upward, which will push the stepping inner tooth wall and the outer gear ring to rotate, and the pushing gear meshing with the outer gear ring drives the pushing rotating rod to rotate, wherein the stepping turntable and the moon-shaped disk at the other end of the pushing rotating rod rotate, and slide along the inner concave surface of the cross groove plate until they rotate one circle and allow the stepping round rod to enter the cross groove After the groove of the plate is formed, the cross-slot plate and the cross-axis rod are pulled to rotate, wherein the conveying rotating gear at the other end of the cross-axis rod rotates, and then the side surface of the conveying rotating gear drives the conveying inner rack and the conveying belt to rotate one circle in turn. When the push plate moves forward again and disengages from the T push frame, the stepping spring pulls the T push frame to reset. At this time, the stepping threaded rod and the stepping rotating rod are rotated, and the one-way paddle rotates in the opposite direction and slides on the inclined surface of the stepping inner tooth wall, and will not push the stepping inner tooth wall to rotate. The paddle spring will continuously push the one-way paddle against the inner wall of the stepping inner tooth wall to avoid the conveying belt returning to its position and blocking the push plate when the T push frame is reset;

[0024] S4. After the two L-shaped splicing plates have finished clamping the stone, according to the calculated parameters, turn the grinding handle to make the adjusting threaded rod rotate together with the cone frame, and the moving block located on the side surface of the adjusting threaded rod begins to move. Since each cone frame has a corresponding grinding handle and adjusting threaded rod at one end, the position of each moving block is adjustable, closer to the position of drilling a hole in the rock in the parameters. Then start the auxiliary push cylinder. Under the push of the output shaft of the auxiliary push cylinder, start the drilling motor at the same time to make the drill rod rotate quickly. After the drill rod moves on the upper surface of the layer plate and the inverted convex plate, it contacts the stone and then drills. Here, the soft The cushion rod plays a buffering role, and then the auxiliary push cylinder pulls the fixed disc to reset, and then turns off the drilling motor, pulls out the drilling pin in the slot, and then inserts the explosives into the fixed disc in turn, and for safety, winds up the remaining explosive fuses, holds the fixed rod so that the kit pin is inserted into the slot, because the position of the moving block is adjusted, the drilling pin is pulled out and then the kit pin is inserted again. The auxiliary push cylinder restarts the push, and after the roller group at the front end of the four extrusion arc plates touches the surface of the stone, the roller group will drive the extrusion arc plate to move forward because the four groups of connecting arc plates and the extrusion arc plates are tilted outwards. The arc pressure plate is unfolded outwards, and at this time, the extrusion arc plate and the connecting arc plate are folded and unfolded while the second folding shaft seat rotates, and the end of the connecting arc plate close to the fixed plate is also opened outwards due to the first folding shaft seat, ensuring that the explosive is inserted into the drilled hole to the maximum extent. At this time, the explosive remains in the hole after the auxiliary propulsion cylinder is reset, and the handle at the other end of the elastic rope is pulled to insert the plug block of the hook into the circular groove, and the extended fuse of the explosive is ignited. The stone air after the explosion flows to the pressure relief nets on both sides for diversion, and the pressure sensor is used to judge the impact of the amount of explosives on the tunnel. At the same time, the remaining impact fragments are blocked by the elastic rope to increase the pressure. With an increased safety factor, when observation is needed, pull out the reinforcement rod above the buckle, turn the locking screw to disengage the shovel-shaped bent rod, hold the handle and move to the other side of the elliptical hollow frame, then lift the arc-shaped ceiling. Here the semicircular ceiling slides on the rear slide on the upper surface of the rear vertical plate, and then observe the condition of the stones after the explosion. After observation, put the arc-shaped ceiling back on. Here the semicircular ceiling is re-shielded by the reset L rod driven by the rear spring. The remaining stone fragments, when the main push cylinder is started to push the stone to feed, are automatically unloaded with the cooperation of the worm, the large worm gear and the transmission worm gear, thus solving the cleaning problem.

[0025] The present invention provides a blasting funnel test experimental device, which has the following beneficial effects:

[0026] The blasting funnel test experimental device, through the linkage of the step connection component and the step push component, can drive the conveying component to move forward one grid in one direction under the push back of the push plate, effectively control the forward range, and cannot be reset in the reverse direction, causing the conveying component to block the push plate, thereby achieving the effect of automatic loading.

[0027] The blasting funnel test experimental device, through the linkage structure between multiple components such as the U-shaped channel assembly, the transmission rack assembly, the positioning assembly and the placement assembly, can automatically clamp and release the stones after the stones are automatically loaded, and after the experiment, it can automatically tilt the waste slag to reduce the cleaning time, ensure the continuity of the experiment, and reduce the workload of the experimenters.

[0028] The blasting funnel test experimental device effectively simulates the impact of tunnel explosions through the structure of the front channel and the rear channel, and the observation top assembly and reset top assembly located on the upper surfaces of the front channel and the rear channel. The pressure sensing device connected to the pressure relief network can also measure the impact of the position and amount of explosives on the tunnel, thereby ensuring the safety of the blasting and increasing the actual effectiveness of the test.

[0029] The blasting funnel test experimental device can quickly unfold the top after blasting by observing the connection structure between the top assembly and the reset top assembly and the front channel and the rear channel, which not only ensures the safety of the blasting, but also ensures the actual situation of the scene after the blasting, effectively observes the blasting effect, and is convenient to close again after observation.

[0030] The blasting funnel test experimental device, and the adjustment component located at the front end of the auxiliary thrust cylinder can adjust the drilling position corresponding to the calculated blasting point, and quickly install the explosives while ensuring that the position remains unchanged, and does not affect the entanglement of the fuses between multiple explosives, and detonate them at the same time, thus restoring the detonation scene to the greatest extent.

[0066] A method for using a bursting funnel test experimental device comprises the following steps:

[0067] S1. First, take out the stone sample that needs to be blasted, and regularize the sample externally, put the uniformly polished stone on the conveying belt 501 in the conveying assembly 5, and then start the output shaft of the main push cylinder 1 and push it forward to push the stone into the channel on the U-shaped frame 601. The front end of the stone in the process of moving forward will push the rectangular stopper 607 to move in the direction of the L-shaped splicing plate 805. Since the upper and lower ends of the special-shaped slider 606 are in the trapezoidal slide 603, the special-shaped slider 606 will move linearly in the trapezoidal slide 603. As the special-shaped slider 606 moves, the toggle rack 608 located on the other side of the special-shaped slider 606 begins to mesh with the side rack of the transmission toothed belt 704. At the same time, since the transmission toothed belt 704 rotates, it will drive the internal linkage wheel 703 to rotate together. At this time, the transmission gear 702 below the side surface of the linkage wheel 703 also rotates, and the three forward push racks 801 meshed with the transmission gear 702 begin to move from the U-shaped frame 601. The hole is expanded outward, and the positioning plate 802 located on the top of the forward rack 801 pulls the door plate 803 and the positioning slider 804 to move along the placement slide 902 in the flat wing plate 901. The positioning threaded sleeve 806 between the two door plates 803 moves along the placement threaded rod 904, and at the same time, the placement threaded rod 904 is rotated in the placement shaft plate 903. The rotating placement threaded rod 904 makes the worm 905 at the other end respectively make the large worm wheel 9011 and the transmission worm wheel 909 When the transmission worm gear 909 rotates, the bevel gear 908 will also be driven to rotate. When the two large worm gears 9011 and the bevel gear 908 rotate, the connecting shaft 906 and the arc sleeve 907 will be turned over. When turning over, the inclined plate 9010 will be turned over together. Here, the stone will first be built on the upper surface between the two flat wing plates 901. At this time, the special-shaped slider 606 will shrink inward along the trapezoidal slideway 603 ramp in the rectangular frame 602, which will not affect the movement of the stone.

[0068] S2, after the push plate 2 passes through the rectangular block 607, after the push plate 2 is reset, the two positioning sliders 804 are repeatedly pulled together toward the middle, and the other end of the positioning plate 802 slides on the side surface of the limiting slide bar 6014, wherein after the special-shaped slider 606 moves to the original position of the rectangular frame 602, after the push plate 2 is continuously squeezed, due to the inclined surface of the rectangular block 607, the special-shaped slider 606 squeezes the reset spring 6010 and moves toward the limiting slider 6011, keeping the two L-shaped splicing plates 805 closed and clamping the stone, keeping the stone on the top of the inclined plate 9010;

[0069] S3. After the push plate 2 is separated from the side surfaces of the U-shaped frame 601 and the conveyor belt 501, the rear side of the push plate 2 pushes the T push frame 301 to move in the direction of the main push cylinder 1, wherein the stepping threaded rod 303 at the bottom of the T push frame 301 rotates inside the side surface of the stepping shaft plate 304, and the stepping rotating rod 302 at the other end drives the middle shaft sleeve 307 to rotate, wherein the groove shaft seat 309 and the one-way paddle 3010 will push the stepping inner tooth wall 308 and the outer gear ring 306 to rotate when moving upward, and the pushing gear 401 meshing with the outer gear ring 306 drives the pushing rotating rod 402 to rotate, wherein the stepping turntable 403 and the moon-shaped disk 404 at the other end of the pushing rotating rod 402 slide along the inner concave surface of the cross groove plate 406 when rotating, until they rotate one circle and allow the stepping round rod 405 to enter the cross groove plate 4 After the groove of 06 is formed, the cross slot plate 406 and the cross shaft rod 407 are pulled to rotate, wherein the conveying rotating tooth 503 at the other end of the cross shaft rod 407 rotates, and then the side surface of the conveying rotating tooth 503 drives the conveying inner rack 502 and the conveying belt 501 to rotate one circle in turn. When the push plate 2 moves forward again and disengages from the T push frame 301, the stepping spring 305 pulls the T push frame 301 to reset. At this time, the stepping threaded rod 303 and the stepping rotating rod 302 are rotated, and the one-way paddle 3010 rotates in the opposite direction and slides on the inclined surface of the stepping inner tooth wall 308, and will not push the stepping inner tooth wall 308 to rotate. The paddle spring 3011 will continuously push the one-way paddle 3010 against the inner wall of the stepping inner tooth wall 308 to avoid the conveying belt 501 returning to its original position and blocking the push plate 2 when the T push frame 301 is reset;

[0070] S4. After the two L-shaped splicing plates 805 have finished clamping the stone, according to the calculated parameters, the grinding handle 1905 is turned to make the adjusting threaded rod 1904 rotate together with the cone frame 1903, and the moving block 1906 located on the side surface of the adjusting threaded rod 1904 begins to move. Since each end of the cone frame 1903 has a corresponding grinding handle 1905 and an adjusting threaded rod 1904, the position of each moving block 1906 is adjustable, which is closer to the position of drilling a hole in the rock in the parameters. Then the auxiliary push cylinder 18 is started. Under the push of the output shaft of the auxiliary push cylinder 18, the drilling motor 2003 is started at the same time to make the drill rod 2004 rotate quickly. After the drill rod 2004 moves on the upper surface of the layer plate 17 and the inverted convex plate 10, it contacts the stone and then moves forward. Drilling is performed, where the cushion layer rod 2002 plays a buffering role, and then the auxiliary push cylinder 18 pulls the fixed disc 1901 to reset, and then the drilling motor 2003 is turned off, the drilling pin 2001 in the plug-in slot 1907 is pulled out, and then the explosives are inserted into the fixed disc 2203 in turn, and for safety, the remaining explosive fuses are wound, and the fixed rod 2202 is held so that the kit pin 2201 is inserted into the plug-in slot 1907. Since the position of the moving block 1906 is adjusted, the drilling pin 2201 is pulled out and then the kit pin 2201 is inserted. Both are still in the original position, and the auxiliary push cylinder 18 restarts the propulsion. After the roller group 2210 at the front end of the four extrusion arc plates 2207 contacts the surface of the stone, due to the four groups of connecting arc plates 2205 and the extrusion The arc plate 2207 is tilted outward, so the roller group 2210 will drive the extrusion arc plate 2207 to expand outward. At this time, the extrusion arc plate 2207 and the connecting arc plate 2205 are folded and expanded while the second folding shaft seat 2206 rotates, and the end of the connecting arc plate 2205 close to the fixed plate 2203 is also opened outward due to the first folding shaft seat 2204, ensuring that the explosive is inserted into the drilled hole to the maximum extent. At this time, the explosive remains in the hole after the auxiliary propulsion cylinder 18 is reset, and the handle 1404 at the other end of the elastic rope 1402 is pulled to allow the plug of the hook 1403 to be inserted into the circular groove 1206, and the extended fuse of the explosive is ignited. The stone airflow after the explosion is diverted to the pressure relief net 13 on both sides, and the pressure sensor is used to judge the impact of the amount of explosive on the tunnel. The impact, at the same time, the remaining impact fragments are blocked by the elastic rope 1402, which increases the safety factor. When observation is needed, pull out the reinforcement rod 21 above the buckle 1505, twist the locking screw 1104 to disengage the shovel-shaped curved rod 1102, hold the handle 1503 and move to the other side of the elliptical hollow frame 1103, and then lift the arc-shaped ceiling 1501. Here, the semicircular ceiling 1601 slides on the rear slide 1205 on the upper surface of the rear vertical plate 1201, and then observe the condition of the stones after the explosion. After observation, put it back into the arc-shaped ceiling 1501. Here, the semicircular ceiling 1601 is pushed by the rear spring 1204 and driven by the reset L rod 1602 to reset and re-block, and the remaining stone fragments, when the main push cylinder 1 is started to push the stone to feed,With the cooperation of the worm 905, the large worm wheel 9011 and the transmission worm wheel 909, the material is automatically unloaded to solve the cleaning problem.

8. The method for using the bursting funnel test experimental device according to claim 7 comprises the following steps: S1. First, take out the stone sample to be blasted and perform external regularization on the sample. Place the uniformly polished stone on the conveying belt (501) in the conveying assembly (5). After the output shaft of the main push cylinder (1) is started, it is pushed forward to push the stone into the channel on the U-shaped frame (601). The front end of the stone being pushed will push the rectangular stopper (607) to move in the direction of the L-shaped splicing plate (805) during the forward movement. Since the upper and lower ends of the special-shaped slider (606) are in the trapezoidal slideway (603), the special-shaped slider (606) will be in the trapezoidal slideway. (603) moves linearly, and as the special-shaped slider (606) moves, the toggle rack (608) located on the other side of the special-shaped slider (606) begins to mesh with the side rack of the transmission toothed belt (704). At the same time, since the transmission toothed belt (704) rotates, it will drive the internal linkage wheel (703) to rotate together. At this time, the transmission gear (702) below the side surface of the linkage wheel (703) also rotates, and the three forward push racks (801) meshed with the transmission gear (702) begin to move from the hole in the U-shaped frame (601) toward The positioning plate (802) located at the top of the forward rack (801) pulls the door plate (803) and the positioning slide block (804) to move along the placement slideway (902) in the flat wing plate (901), wherein the positioning threaded sleeve (806) between the two door plates (803) moves along the placement threaded rod (904), while causing the placement threaded rod (904) to rotate in the placement shaft plate (903), and the rotating placement threaded rod (904) causes the worm (905) at the other end to respectively cause the large worm wheel (9011) and the transmission worm wheel (9011) to rotate. 9) rotates, wherein the transmission worm gear (909) rotates and also drives the bevel gear (908) to rotate, wherein the two large worm gears (9011) and the bevel gear (908) rotate, which causes the connecting shaft (906) and the arc sleeve (907) to flip, and when flipping, the inclined plate (9010) flips together, and the stone is first built on the upper surface between the two flat wing plates (901), and at this time, the special-shaped slider (606) retracts inward along the trapezoidal slideway (603) ramp in the rectangular frame (602), without affecting the movement of the stone; S2, after the push plate (2) passes through the rectangular stopper (607), after the push plate (2) is reset, the two positioning sliders (804) are repeatedly pulled together toward the middle, and the other end of the positioning plate (802) slides on the side surface of the limiting slide bar (6014), wherein after the special-shaped slider (606) moves to the original position of the rectangular frame (602), after the push plate (2) is continuously squeezed, due to the inclined surface of the rectangular stopper (607), the special-shaped slider (606) squeezes the reset spring (6010) and moves toward the limiting slider (6011), thereby keeping the two L-shaped splicing plates (805) closed and clamping the stone, and keeping the stone on the top of the inclined plate (9010); S3. After the push plate (2) is separated from the side surfaces of the U-shaped frame (601) and the conveyor belt (501), the rear side surface of the push plate (2) pushes the T push frame (301) to move in the direction of the main push cylinder (1), wherein the stepping threaded rod (303) at the bottom of the T push frame (301) rotates inside the side surface of the stepping shaft plate (304), and the stepping rotating rod (302) at the other end drives the middle shaft sleeve (307) to rotate, wherein the groove shaft seat (309) and the one-way paddle When (3010) moves upward, it pushes the stepping inner tooth wall (308) and the outer tooth ring (306) to rotate, and the pushing gear (401) meshing with the outer tooth ring (306) drives the pushing rod (402) to rotate, wherein the stepping turntable (403) and the moon-shaped disk (404) at the other end of the pushing turntable (402) slide along the inner concave surface of the cross groove plate (406) when rotating, until after rotating one circle, the stepping round rod (405) enters the cross groove plate ( After the groove of the T push frame (301) is formed, the cross slot plate (406) and the cross shaft (407) are pulled to rotate, wherein the conveying gear (503) at the other end of the cross shaft (407) rotates, and then the side surface of the conveying gear (503) drives the conveying inner rack (502) and the conveying belt (501) to rotate one circle in turn. When the push plate (2) moves forward again and disengages from the T push frame (301), the stepping spring (305) pulls the T push frame (301) to reset, and at this time, the stepping spring (305) is rotated. The threaded rod (303) and the stepping rotating rod (302) rotate in the opposite direction, and the one-way paddle (3010) will slide on the inclined surface of the stepping inner tooth wall (308) and will not push the stepping inner tooth wall (308) to rotate. The paddle spring (3011) will continuously push the one-way paddle (3010) toward the inner wall of the stepping inner tooth wall (308) to prevent the conveying belt (501) from returning to its original position and blocking the push plate (2) when the T push frame (301) is reset; S4. After the two L-shaped splicing plates (805) have finished clamping the stone, the arrangement point of the explosives on the stone is determined according to the calculated parameters, and then the grinding handle (1905) is turned to allow the adjusting threaded rod (1904) to rotate together with the cone frame (1903), and the moving block (1906) located on the side surface of the adjusting threaded rod (1904) begins to move. Since each cone frame (1903) has a corresponding grinding handle (1905) and an adjusting threaded rod (1904) at one end, the position of each moving block (1906) is adjustable, closer to the position of drilling a hole in the rock in the parameters, and then the auxiliary push cylinder (18) is started. Under the push of the output shaft of the auxiliary push cylinder (18), the drilling motor (2003) is started at the same time. The drill rod (2004) is rotated quickly. After the drill rod (2004) moves on the upper surface of the layer plate (17) and the inverted convex plate (10), it contacts the stone and then drills. Here, the cushion layer rod (2002) plays a buffering role. Then, the auxiliary push cylinder (18) pulls the fixed disc (1901) to reset. After the drilling motor (2003) is turned off, the drilling plug (2001) in the plug slot (1907) is pulled out, and then the explosives are inserted into the fixed disc (2203) in sequence. For safety, the remaining explosive fuses are wound, and the fixed rod (2202) is held so that the kit plug (2201) is inserted into the plug slot (1907). Since the position of the moving block (1906) is adjusted, the drilling plug (2001) is pulled out and then The insertion kit latches (2201) are still in their original positions, and the auxiliary push cylinder (18) restarts to push. After the roller group (2210) at the front end of the four extrusion arc plates (2207) contacts the surface of the stone, since the four groups of connecting arc plates (2205) and the extrusion arc plates (2207) are inclined outward, the roller group (2210) will drive the extrusion arc plates (2207) to unfold outward. At this time, the extrusion arc plates (2207) and the connecting arc plates (2205) are folded and unfolded while the second folding shaft seat (2206) rotates, and the end of the connecting arc plate (2205) close to the fixed plate (2203) is also opened outward due to the first folding shaft seat (2204), ensuring that the explosive is inserted into the drilled hole to the maximum extent. At this time, the auxiliary push cylinder ( 18) After reset, the explosives remain in the hole, and the pull handle (1404) at the other end of the elastic rope (1402) is pulled to insert the plug of the hook (1403) into the circular groove (1206), and the extended fuse of the explosives is ignited. The stone gas after the explosion flows to the pressure relief nets (13) on both sides for diversion, and the impact of the amount of explosives on the tunnel is judged by the pressure sensor. At the same time, the remaining impact fragments are blocked by the elastic rope (1402), which increases the safety factor. When observation is required, the reinforcement rod (21) above the buckle (1505) is pulled out, and the locking screw (1104) is turned to separate from the shovel-shaped curved rod (1102), and then the handle (1503) is held and moved to the other side of the elliptical hollow frame (1103), and then the arc-shaped ceiling (1501) is lifted.Here, the semicircular ceiling (1601) slides on the rear slideway (1205) on the upper surface of the rear vertical plate (1201), and then observes the condition of the stones after the explosion. After observation, it is put back into the arc-shaped ceiling (1501). Here, the semicircular ceiling (1601) is driven by the rear spring (1204) to reset and re-block through the reset L rod (1602). When the main push cylinder (1) is started to push the stones to load, the remaining stone fragments are automatically unloaded under the cooperation of the worm (905), the large worm wheel (9011) and the transmission worm wheel (909), thereby solving the cleaning problem.
