The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0048] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0049] like Figures 1 to 16 As shown, a self-adjusting drilling probe machine of the present invention comprises a frame 100, a slide 110, a drop hammer unit 200, a transmission unit 120 and an adjustment unit 300, the frame 100 is provided with a stationary rod 101 in the vertical direction, one end of the stationary rod 101 is connected to the frame 100, and the other end is a free end, a probe 102 is provided on the outer sliding sleeve of the stationary rod 101, and the lower end of the probe 102 is arranged in a sampling hole on the soil surface, and the probe 102 moves downward to penetrate into the soil for drilling;

[0050] The drop hammer unit 200 includes a plurality of drop hammers 210, which are slidably mounted on the stationary rod 101 in sequence and are coaxially sleeved. The inner diameters of the plurality of drop hammers 210 are different. The inner diameter of the outermost drop hammer 210 is the largest and is equal to the outer diameter of the drop hammer 210 adjacent thereto. The inner diameter of the innermost drop hammer 210 is equal to the outer diameter of the stationary rod 101. Two adjacent drop hammers 210 are matched with each other. Each drop hammer 210 is provided with a receiving boss 220. A receiving groove extending in the vertical direction is provided at the position corresponding to 20, and the connection between the receiving boss 220 and the drop hammer 210 is located in the receiving groove of the adjacent drop hammer 210. The lower drop hammer 210 of the two adjacent drop hammers 210 receives the upper drop hammer 210 through the receiving boss 220. When multiple drop hammers 210 are sleeved together, the receiving boss 220 abuts against each other. The process of multiple drop hammers 210 hitting the probe 102 in sequence from the outermost layer to the innermost layer is a complete hitting process.

[0051] The transmission unit 120 is used to lift the plurality of drop hammers 210 to the expected striking height and then disengage from the drop hammer 210, so that the plurality of drop hammers 210 strike the probe 102 in sequence. The initial positions of the plurality of drop hammers 210 are placed on the probe 102. The transmission unit 120 lifts the outermost drop hammer 210. Since the drop hammers 210 are pressed against each other in sequence by the receiving boss 220, all the drop hammers 210 are lifted. When the drop hammers 210 are lifted to the expected height by the transmission unit 120, the drop hammers 210 from the outermost layer to the innermost layer are disengaged from the transmission unit 120 in sequence, and strike the probe 102 in sequence. After all the drop hammers 210 strike the probe 102 in sequence, a complete striking process ends. At this time, all the drop hammers 210 return to the initial positions, waiting for the next contact between the transmission unit 120 and the outermost drop hammer 210.

[0052] The adjusting unit 300 can self-adjust the height of each drop hammer 210 hitting the probe 102. In a complete hitting process, each hitting of the drop hammer 210 will cause the probe 102 to fall a certain distance, and this distance is different in different places due to the different soil properties. The distance of each drop is different and unknown. The distance that the drop hammer 210 is lifted each time is fixed. The distance from the free fall of the drop hammer 210 to the hitting of the upper end of the probe 102 increases each time, that is, the distance of each hitting is different and increases in sequence. The adjusting unit 300 can make the heights of multiple drop hammers 210 falling and hitting the probe 102 consistent in each complete hitting process, thereby ensuring the effectiveness of the hitting.

[0053] It should be added that the self-adjusting drilling probe machine of the present invention also includes a slide 110, which is slidably arranged on the frame 100 in the vertical direction, and a positioning hole is arranged at the bottom of the slide 110, and the upper end of the probe 102 is connected to the positioning hole, and a boss is arranged on the positioning hole, and the upper end of the probe 102 is flush with the boss, and the sliding of the probe 102 drives the slide 110 to slide; the transmission unit 120 includes a rocker 121 and a motor 122, and the rocker 121 and the motor 122 are both arranged on the slide 110, and the rotation center of the rocker 121 is located on one side of the drop hammer 210, and the motor 122 drives the rocker 121 to do the work from the receiving boss. The receiving boss 220 can rotate from the bottom to the top of the receiving boss 220, and the end of the receiving boss 220 on the same side as the rotation center is located within the range covered by the rotation circle of the rocker 121. The rocker 121 can contact or disengage from the receiving boss 220. The contact and rotation of the rocker 121 and the receiving boss 220 can drive the receiving boss 220 to move, thereby driving the drop hammer 210 to lift. When the rocker 121 is disengaged from the receiving boss 220, the drop hammer 210 falls freely. Compared with using a chain as a transmission mechanism to lift the drop hammer 210, it is not easy for the drop hammer 210 to slip, which greatly ensures the stability and efficiency of the transmission.

[0054] In a further embodiment, referring to Figure 7 The adjusting unit 300 includes a plurality of bases 310 and an action component 400. The number of the bases 310 corresponds to the number of the drop hammers 210. The plurality of bases 310 are sequentially sleeved on the stationary rod 101. The innermost base 310 is arranged at the upper end of the probe 102. The lower base 310 of the two adjacent bases 310 receives the upper base 310. Except for the outermost base 310, the upper ends of all the other bases 310 are provided with corresponding impact blocks 320. The lower end surface of the impact block 320 contacts the upper end surface of the corresponding base 310. The action component 400 can make the base 310 move relative to the corresponding impact block 320, so that the impact block 320 remains stationary relative to the stationary rod 101, that is, the impact block 320 maintains its original position relative to the stationary rod 101 when the base 310 moves relatively.

[0055] In one embodiment, referring to Figure 5There are three drop hammers 210, which are defined as drop hammer 1 211, drop hammer 2 212 and drop hammer 3 213 from the outermost layer to the innermost layer, and there are three bases 310, which are defined as base 1 311, base 2 312 and base 3 313 from the outermost layer to the innermost layer, the impact block 320 corresponding to base 2 312 is impact block 1 321, and the impact block 320 corresponding to base 3 313 is impact block 2 322; the lower end of base 313 contacts the upper end of probe 102, base 2 312 is sleeved on the outside of base 3 313, base 1 311 is sleeved on the outside of base 2 312, impact block 2 322 is slidably sleeved on stationary rod 101, and the lower end is in contact with base 3 313 The upper end of the impact block 1 321 is slidably sleeved on the outside of the impact block 2 322, and the lower end is in contact with the upper end of the base 2 312; the inner diameter of the base 1 311 is the same as the inner diameter of the drop hammer 1 211, the inner diameter of the base 2 312 is the same as the inner diameter of the drop hammer 212, the inner diameter of the base 313 is the same as the inner diameter of the drop hammer 3 213 and the outer diameter of the stationary rod 101, the position of the impact block 1 321 corresponds to that of the base 2 312, the position of the impact block 2 322 corresponds to that of the base 3 313, in the vertical direction, the upper end surfaces of the base 1 311, the base 2 312 and the base 3 313 are on the same horizontal plane, and the upper end surface of the impact block 1 321 is lower than the upper end surface of the impact block 2 322;

[0056] In a complete hammering process, the drop hammer 1 211, the drop hammer 212 and the drop hammer 3 213 are lifted up by the rocker 121 in sequence and then separated from the rocker 121 and fall freely. The difference in the lifting height between two adjacent drop hammers 210 is equal to the height of the impact block 320 corresponding to the later dropped drop hammer 210. The drop hammer 1 211 hits the base 1 311, and the base 1 311 pushes the probe 102 into the soil for a distance through the base 2 312 and the base 3 313. Then, the base 1 311, the base 2 312 and the base 3 313 are lifted up and the impact block 320 is released. As the probe 102 falls a certain distance, the action component 400 can make the impact block 1 321 still when the base 2 312 falls, and make the impact block 2 322 still when the base 313 falls, so that the impact block 1 321 and the impact block 2 322 are still located at the initial position, and the probe 102, the base 1 311, the base 2 312, the base 3 313 and the drop hammer 1 211 all fall a certain distance relative to the initial position; the drop hammer 212 falls freely and hits the impact block 1 321, and the impact block 1 321 pushes the base 2 313 to move. 2. The base 2 312 pushes the base 3 313, and the base 3 313 pushes the probe 102 to fall a certain distance. During this process, there is no relative movement between the impact block 1 321 and the base 2 312, and there is relative movement between the impact block 2 322 and the base 3 313. The action component 400 makes the impact block 2 322 stationary, and the probe 102, the base 1 311, the impact block 1 321, the base 2 312, the base 3 313 and the drop hammer 2 212 fall a certain distance; the drop hammer 3 213 falls freely and hits the impact block 2 322. The impact block 2 322 pushes the base 313, and the base 313 pushes the probe 102 to fall a certain distance. All the drop hammers 210, all the bases 310 and all the impact blocks 320 fall a certain distance with the probe 102, and then a complete striking process is ended. Because the stillness of the impact block 320 makes up for the distance that the probe 102 fell during the last impact, the free fall heights of all the drop hammers 210 are equal, which not only increases the efficiency of the striking but also makes the striking distance consistent, thereby ensuring the efficiency of the probing and making the probing process accurate and effective.

[0057] In a further embodiment, referring to Figure 7The action component 400 includes a plurality of sliders 420, ratchets 410 and pawls 430. The impact block 320 is provided with a sliding groove 323 uniformly distributed along the circumferential direction. The end of the sliding groove 323 close to the stationary rod 101 is higher than the end away from the stationary rod 101 in the vertical direction. Each slider 420 corresponds to the sliding groove 323 one by one. The slider 420 is slidably arranged in the sliding groove 323. The end of each slider 420 close to the stationary rod 101 is an arc surface; notches 314 are uniformly distributed along the circumferential direction in the base 310. The notch 314 takes the vertical direction as the length direction. A ratchet 410 is arranged on the side of the notch close to the stationary rod 101. A square platform is extended from the lower part of the slider 420. A pawl 430 is arranged on the square platform. The ratchet 410 and the pawl 430 cooperate to make the slider 420 and the base 310 move away from each other. When the slider 420 is located at the farthest distance from the stationary rod 101, the pawl 430 and the ratchet 410 are engaged. 0 is disengaged, when the slider 420 is located at the closest point to the stationary rod 101, the pawl 430 cooperates with the ratchet 410; the outermost base 310 has a magnet 330 embedded in it, and each slider 420 is provided with a magnetic block that repels the magnet 330, and the magnetic blocks on the sliders 420 in two adjacent impact blocks 320 repel each other. Because the slide groove 323 is inclined, the initial position of the slider 420 is the farthest from the stationary rod 101. When the drop hammer 210 falls freely to hit the outermost base 310, the repulsive force between the magnetic block and the magnet 330 causes the slider 420 to move closer to the stationary rod 101 until it can no longer move closer to the stationary rod 101. At this time, the pawl 430 cooperates with the ratchet 410, and when the base 310 moves downward relative to the corresponding impact block 320, the friction between the slider 420 and the contact point causes the impact block 320 to stop, so that the impact block 320 maintains its initial position.

[0058] In a further embodiment, a surface of the slider 420 close to the stationary rod 101 is roughened to increase the friction between the slider 420 and the contact surface, making the slider 420 less likely to slide and thus making the impact block 320 less likely to slide.

[0059] In a further embodiment, the action component 400 further includes a resisting spring, which contacts the pawl 430 , and the resisting spring makes the pawl 430 tend to maintain its original state.

[0060] In a further embodiment, the magnet 330 embedded in the base 310 is annular.

[0061] In another embodiment, there are two rocking arms 121, and the two rocking arms 121 are symmetrically arranged on both sides of the drop hammer 210. The rocking arm 121 arranged on the left side of the drop hammer 210 rotates in the counterclockwise direction, and the rocking arm 121 arranged on the right side of the drop hammer 210 rotates in the clockwise direction. The two rocking arms 121 are in contact with or disengaged from the receiving boss 220 at the same time, so as to balance the force on both sides of the receiving boss 220, so that the drop hammer 210 is evenly stressed and wear is reduced.

[0062] In a further embodiment, the transmission unit 120 further includes a transmission gear, and the transmission gear causes the two rocking arms 121 to rotate in opposite directions.

[0063] In a further embodiment, the self-adjusting probe of the present invention further comprises a counter for recording the number of blows.

[0064] In combination with the above embodiments, the use principle and working process of the present invention are as follows:

[0065] The overall work process steps are: Figure 4-Figure 6 - Figure 8-Figure 9 - Figure 11-13 - Figure 4 , Figure 4 The first hammer 211, the second hammer 212 and the third hammer 213 are in their initial positions. At this time, the slider 420 in the impact block 1 321 is kept close to the impact block 2 322 due to the repulsive force of the magnet 330, and the slider 420 in the impact block 2 322 is kept close to the stationary rod 101 due to the repulsive force of the magnet 330. When the motor 122 is turned on, the rocker 121 on the left side of the first hammer 211 makes a counterclockwise rotation motion, and the rocker 121 on the right side of the first hammer 211 makes a clockwise rotation motion. When the two rockers 121 are simultaneously in contact with the When the receiving boss 220 on the drop hammer 1 211 contacts, the rotating end of the rocker 121 pushes the receiving boss 220 to lift the drop hammer 1 211. Because the receiving boss 220 of the drop hammer 1 211 abuts against the receiving boss 220 of the drop hammer 212, and the receiving boss 220 of the drop hammer 212 abuts against the receiving boss 220 of the drop hammer 3 213, the drop hammer 1 211 drives the drop hammers 212 and 213 to lift in the vertical direction. The slider 420 slides to the farthest distance from the stationary rod 101 due to gravity. This process is called from Figure 4 becomes Figure 6 ;

[0066] When the first drop hammer 211 is disengaged from the rocker 121, the rocker 121 contacts the receiving boss 220 of the second drop hammer 212, and the first drop hammer 211 falls freely. Figure 8 When the drop hammer 1 211 hits the base 1 311, the drop hammer 212 is separated from the rocker 121, and the drop hammer 212 is in a free-falling state. Fig. 9 When the second drop hammer 212 hits the impact block 1 321, the third drop hammer 213 is separated from the rocker 121 and is in a free-falling state. Fig.11 When the drop hammer 3 213 hits the impact block 2 322, a complete hitting process ends;

[0067] When the drop hammer 1 211 falls and approaches the base 1 311, the repulsive force of the magnet 330 causes the sliders 420 of the impact block 1 321 and the impact block 2 322 to slide close to the stationary rod 101, until the slider 420 in the impact block 1 321 is pressed on the surface of the impact block 2 322, and the slider 420 in the impact block 2 322 is pressed on the surface of the stationary rod 101, and all the ratchet pawls 430 cooperate with the ratchet teeth 410. When the drop hammer 1 211 hits the base 1 311, the force of the drop hammer 1 211 is transmitted to the base 2 312 through the base 1 311, and then transmitted to the base 2 312 through the base 1 311. The second 312 is transmitted to the base three 313, and then transmitted to the probe 102 through the base three 313, so that the probe 102 falls a certain distance. During this process, the base two 312 falls a certain distance relative to the impact block one 321, and the base three 313 falls the same distance relative to the impact block two 322. The cooperation between the ratchet 410 and the pawl 430 and the repulsive force generated by the magnet 330 make the impact block one 321 and the impact block two 322 stationary, and the distance between the impact block one 321 and the base two 312 becomes larger, and the distance between the impact block two 322 and the base three 313 becomes larger. This process is from Figure 6 becomes Figure 8 Later becomes Fig. 9 When the second hammer 212 hits the impact block 1 321, the force of the second hammer 212 is transmitted to the second base 312 through the impact block 1 321, and then to the third base 313 through the second base 312, and then to the probe 102 through the third base 313, so that the probe 102 falls a distance again. During this process, the third base 313 falls a distance relative to the second impact block 322, then the second impact block 322 is stationary, and the distance between the second impact block 322 and the third base 313 is further increased. This process is from Fig. 9 When the hammer 213 hits the impact block 222, the force of the hammer 213 is transmitted to the probe 102 through the base 313, causing the probe 102 to further drop a distance. During this process, the impact block 222 maintains a distance from the base 313 and falls relative to the stationary rod 101 for a distance. This process is from Fig.11 becomes Fig.13 , a complete hammering process is completed, and when the rocker 121 rotates back to contact the receiving boss 220 of the drop hammer 211 again, the next complete hammering process is carried out.
