DETAILED DESCRIPTION

[0020] like Figure 1-Figure 10As shown, an engineering design on-site survey device and survey method include a base 1 and a drill pipe 12 arranged above the base 1, a spiral blade 1201 is fixedly installed on the outer side of the drill pipe 12, and a drill bit is fixedly installed on the bottom end of the drill pipe 12, and a through hole is opened at the center position of the base 1 to facilitate the drill pipe 12 and the spiral blade 1201 on the outer side of the drill pipe 12 to pass through.

[0021] In order to drive the drill pipe 12 to move downward, a connecting pipe 7 is fixedly connected to the top of the drill pipe 12 by screws, and a connecting block 10 is arranged on the outside of the connecting pipe 7 and near the top. The connecting pipe 7 passes through the connecting block 10 and rotates with it, and the two sides of the connecting block 10 are detachably connected with the lifting plate 9. In actual use, the connecting block 10 can be fixed to the lifting plate 9 by bolt connection. A screw rod 6 is arranged at the lifting plate 9, and the screw rod 6 passes through the lifting plate 9 and is threadedly connected with it. Through this structure, the connecting pipe 7 and the drill pipe 12 can be driven to move downward. In addition, a motor is installed under one of the lifting plates 9, and the motor is transmission-connected with the connecting pipe 7. Specifically, the output shaft of the motor passes through the lifting plate 9 and is fixedly sleeved with a gear, and the output shaft of the motor rotates with the lifting plate 9. The outer side of the connecting pipe 7 is fixedly sleeved with a gear ring 8 meshing with the gear, so as to drive the connecting pipe 7 and the drill pipe 12 to rotate. Through this structure, the drill pipe 12 can be drilled into the ground and the soil can be transported to the ground through the spiral blade 1201.

[0022] In order to preserve the soil transported by the spiral blade 1201, the present invention provides a left panel 2 and a right panel 3 on both sides of the top of the base 1. The left panel 2 and the right panel 3 are both arc-shaped structures. When the left panel 2 and the right panel 3 are attached to each other, a complete cylindrical structure can be formed. The left panel 2 and the right panel 3 can be attached to the outside of the spiral blade 1201. Limiting strips 4 are fixedly provided on both the front and rear sides of the top of the base 1. When the left panel 2 and the right panel 3 are attached to each other and clamped, the left panel 2 and the right panel 3 can slide and cooperate with the limiting strips 4. Further, a fender 202 is elastically mounted on the left panel 2, and the fender 202 can move along the diameter direction relative to the left panel 2. Figure 13-Figure 15As shown, the mudguard 202 can be inserted into the spiral blade 1201, and the height of the mudguard 202 is slightly smaller than the pitch of the spiral blade 1201, that is, when the mudguard 202 is inserted into the spiral blade 1201, the bottom surface of the mudguard 202 can contact the top surface of the spiral blade 1201, and there is only a small distance between the top surface of the mudguard 202 and the bottom surface of the spiral blade 1201. Since the mudguard 202 is restricted by the left enclosure 2 and cannot rotate, the rotation of the spiral blade 1201 can drive the mudguard 202 to move upward, thereby driving the left enclosure 2 and the right enclosure 3 to move upward relative to the drill pipe 12.

[0023] Reference Figure 1-Figure 9 As shown, a spiral support plate 16 is fixedly provided on the outer side of the drill pipe 12, and the bottom end of the support plate 16 fits with the top end of the spiral blade 1201, so that the baffle 1601 can slide from the spiral blade 1201 to the support plate 16, and the top surface of the support plate 16 is connected with a plurality of baffles 1601 through a clamping assembly, and two adjacent baffles 1601 fit each other. In actual application, the thickness of the support plate 16 can be greater than or equal to the thickness of the spiral blade 1201, and the top surface of the baffle 1601 adjacent to the spiral blade 1201 and near the bottom end can be chamfered, so as to facilitate the fender 2 02 moves to the baffle 1601, and the baffle 1601 can be locked on the support plate 16 through the provided clamping assembly to prevent the baffle 1601 from sliding relative to the support plate 16. When the two adjacent baffles 1601 are separated, the clamping assembly on the baffle 1601 at the bottom is disengaged from the support plate 16, so that the baffle 1601 can move relative to the support plate 16. The baffle 1601 is a spiral structure, and the baffle 1601 only rotates one circle, so that the two ends of the baffle 1601 are on the same vertical plane. The bottom surface of the mudguard 202 is elastically connected with a push block 17. Figure 14-17 As shown, a notch 20 is provided on the top surface of the baffle 1601 near the bottom end thereof to match the push block 17. Figure 2-Figure 6 , Fig.12As shown, both sides of the bottom end of the push block 17 are set to a fourth inclined surface 1703. When the push block 17 is in a pop-up state and inserted into the slot 20, the fourth inclined surface 1703 can contact the side edge of the slot 20. When the left panel 2 and the right panel 3 that are fitted to each other move upward so that the mudguard 202 moves to the top baffle 1601, the top baffle 1601 can be connected to the mudguard 202 through the cooperation between the push block 17 and the slot 20, which causes the top baffle 1601 to be unable to rotate synchronously with the support plate 16. At this time, when the spiral support plate 16 rotates, the force of the support plate 16 on the baffle 1601 can drive the baffle 1601 and the left and right panels 2 and 3 outside it to move upward, and the cooperation between the mudguard 202 and the baffle 1601 can prevent the soil inside the left and right panels 2 and 3 from falling, thereby completing the soil collection.

[0024] The vertical height between the top surface of the baffle 1601 and the bottom surface of the support plate 16 is equal to the pitch of the spiral blade 1201 . The purpose of this arrangement is to enable the mud guard 202 to slide between the baffle 1601 and the support plate 16 .

[0025] like Figure 3-Figure 17 As shown, the clamping assembly includes a clamping block 22 disposed on the bottom surface of the baffle 1601 and elastically matched with the baffle 1601. The clamping block 22 is disposed near the top of the baffle 1601, and a clamping groove 1602 matching with the clamping block 22 is provided on the top surface of the support plate 16. Fig.12 As shown, both sides of the bottom end of the card block 22 are provided with inclined extrusion parts 2201. In the initial state, the extrusion part 2201 is completely placed in the card slot 1602. At this time, the card block 22 cooperates with the card slot 1602 through the straight edge of its side, which is conducive to locking the baffle 1601 on the support plate 16; Furthermore, a limiting rod 21 is arranged above the block 22, the limiting rod 21 is elastically matched with the baffle 1601, and a groove 2101 is provided on the bottom surface of the limiting rod 21, and a push rod 2202 is fixedly arranged on the top surface of the block 22. When the two baffles 1601 are in contact with each other, the limiting rod 21 is compressed in the baffle 1601, and when the two baffles 1601 are separated from each other, the limiting rod 21 can pop out so that the push rod 2202 can be aligned with the groove 2101. At this time, the block 22 can move upward so that the extrusion portion 2201 on the block 22 can be aligned with the side edge of the slot 1602, thereby providing conditions for the block 22 to move out of the slot 1602.

[0026] Reference Figure 1-Figure 4As shown, a boss 204 is provided above the fender 202, the boss 204 is fixed on the outer wall of the left enclosure 2, and a latch is provided at the boss 204, and a socket matching with the latch is provided at the top surface of the fender 202, so as to lock the fender 202 with the left enclosure 2; In actual use, the lifting plate 9 and the connecting block 10 are driven downward by the screw rod 6, thereby driving the connecting pipe 7 and the drill pipe 12 to move downward, and the spiral blade 1201 can be used to transport soil to the ground. When the drill pipe 12 moves downward to the corresponding depth, the pin can be pulled upward, so that the mudguard 202 can pop up in the direction close to the drill pipe 12 and insert into the spiral blade 1201. Since the left and right panels 2 and 3 are slidably matched with the limit strip 4, the left and right panels 2 and 3 cannot rotate, which causes the mudguard 202 to only move in the vertical direction with the left panel 2. The rotation of the spiral blade 1201 can drive the mudguard 202 to move upward, thereby driving the left and right panels 2 and 3 to move upward synchronously, and the soil located inside the left and right panels 2 and 3 and on one side of the mudguard 202 can be pushed by the mudguard 202 and move upward along the spiral blade 1201. When the fender 202 is moved by the spiral blade 1201 to the top of the support plate 16, the fender 202 can move along the upper surface of the baffle 1601. Since the top of the baffle 1601 is locked with the support plate 16 by the block 22, when the push block 17 is aligned with the slot 20 and inserted into the slot 20, the cooperation between the push block 17 and the slot 20 cannot drive the baffle 1601 below the support plate 16 to move, but the block 22 on the top baffle 1601 is not completely inserted into the slot 1602. When the fender 202 moves to the top baffle 1601 and the push block 17 is inserted into the slot 20 on the top baffle 1601, the force between the push block 17 and the slot 20 is sufficient to move the baffle 1601 to the top. The block 22 on 1601 is pulled out from the slot 1602, so that the baffle 1601 at the top can move synchronously with the mudguard 202 relative to the support plate 16. As the support plate 16 continues to rotate, the force exerted by the support plate 16 on the baffle 1601 at the top can drive it to move upward, thereby driving the mudguard 202, the left enclosure 2 and the right enclosure 3 to move upward. When the left enclosure 2 and the right enclosure 3 move upward to the outside of the connecting pipe 7, the spiral baffle 1601 can contact the outer wall of the connecting pipe 7. At this time, the baffle 1601, the mudguard 202, the left enclosure 2, the right enclosure 3 and the connecting pipe 7 form a relatively closed storage space, and only the upper part of this storage space is open, and the collected soil is stored in this storage space; When the top baffle 1601 moves relative to the support plate 16, the limit rod 21 at one end of the second baffle 1601 from top to bottom will pop out, so that the top rod 2202 can be aligned with the groove 2101, and the block 22 can move upward relative to the baffle 1601. Fig.12 As shown, when the block 22 moves upward relative to the baffle 1601, the extrusion portion 2201 on the block 22 will be aligned with the side edge of the slot 1602. Subsequently, when the next group of left enclosure 2 and right enclosure 3 move to this baffle 1601, the block 22 can be pulled out of the slot 1602 through the cooperation of the push block 17 and the notch 20, so that this baffle 1601 can also move relative to the support plate 16. By repeating the above operation, each baffle 1601 can be called from top to bottom in turn, so as to cooperate with the fender 202, the left enclosure 2 and the right enclosure 3 to store soil. Since multiple groups of left enclosures 2 and right enclosures 3 are all on the outside of the connecting pipe 7, after the survey is completed, the connecting pipe 7 can be directly removed from the drill pipe 12 to seal multiple groups of soil samples.

[0027] To sum up, when this device is used, the mudguard 202 can drive the soil stored in the inner cavity of the left enclosure 2 and the right enclosure 3 to move upward along the spiral blade 1201, and by arranging multiple baffles 1601 on the support plate 16, the baffles 1601 can be called in sequence from top to bottom during the upward movement of the mudguard 202. At this time, the baffle 1601 can block the bottom of the left enclosure 2 and the right enclosure 3. When the mudguard 202 moves to the connecting pipe 7, the mudguard 202, the baffle 1601, the left enclosure 2, the right enclosure 3 and the connecting pipe 7 form a space for storing soil. Later, the connecting pipe 7 can be removed from the drill pipe 12 to seal multiple groups of soil samples. The overall operation is quick and can prevent different samples from mixing together.

[0028] The baffle 1601 is elastically connected to a positioning rod 19 at the notch 20, and a positioning hole 1702 matching the positioning rod 19 is provided on the push block 17. Further, a vertical rod 18 is provided below the positioning rod 19, and the vertical rod 18 is elastically connected to the baffle 1601. A slot matching the vertical rod 18 is provided on the bottom surface of the positioning rod 19. In the initial state, the top end of the vertical rod 18 is in the slot, so as to lock the positioning rod 19. Figure 10-Figure 16As shown, a magnetic plate 1603 is fixedly embedded on the top surface of the support plate 16 near the top, and a magnetic block matching the magnetic plate 1603 can be fixedly embedded on the bottom end surface of the vertical rod 18. The magnetic block has different magnetic poles on the side opposite to the magnetic plate 1603. In actual use, when the push block 17 cooperates with the slot 20 and drives the baffle 1601 to move upward along the support plate 16, the baffle 1601 can pass through the magnetic plate 1603, and when the vertical rod 18 moves to the magnetic plate 1603, the suction force between the magnetic plate 1603 and the magnetic block can drive the vertical rod 18 to move downward, thereby separating the vertical rod 18 from the positioning rod 19. At this time, the positioning rod 19 can pop out and be inserted into the positioning hole 1702, so that the push block 17 can be locked with the baffle 1601 to prevent the two from separating.

[0029] like Figure 1-Figure 2 As shown, brackets 11 are fixedly provided on both sides of the top of the base 1, and the brackets 11 are arranged in an L shape. The two ends of the screw rod 6 are rotatably matched with the brackets 11 and the base 1 respectively (the two ends of the screw rod 6 are arranged as a bare rod structure), and the bottom end of the screw rod 6 passes through the base 1, and a driving motor is installed under the base 1, and the output end of the driving motor is transmission-connected with one end of the screw rod 6 passing through the base 1, so as to drive the screw rod 6 to rotate forward and reverse.

[0030] A support frame is fixedly arranged outside the limiting strip 4 and near the top. The support frame is U-shaped and fixedly connected to the bracket 11. A roller is installed at the bottom end of the base 1.

[0031] The outer side of the connecting tube 7 is provided with a pressing ring 23, and the pressing ring 23 is fixedly arranged on the bottom surface of the connecting block 10. Through this structure, the connecting block 10 can more stably drive the connecting tube 7 to move downward, and the connecting tube 7 can cooperate with the connecting block 10 through a tapered roller bearing.

[0032] The inner side of the limit strip 4 is provided with a plurality of vertical limit grooves 401, and the left and right enclosure plates 2 and 3 are both extended outward at both ends to form convex strips, and the outer side of the convex strip is provided with a mounting groove, and a limit block 13 is slidably arranged in the mounting groove, and a limit spring is fixedly arranged between the limit block 13 and the inner end surface of the mounting groove, and the ... Figure 1-Figure 6 As shown, the limiting strip 4 is provided with inclined extrusion surfaces 402 on one side close to the drill pipe 12 and at both sides. In actual use, when the left enclosure 2 and the right enclosure 3 are pushed to fit the outside of the spiral blade 1201, the convex strip can move to the inside of the limiting strip 4, and the limiting block 13 can move to the limiting groove 401 through the extrusion surface 402. The cooperation between the limiting block 13 and the limiting groove 401 can prevent the left enclosure 2 or the right enclosure 3 from rotating. Furthermore, combined with Figure 1-Figure 7As shown, the limit block 13 is provided with a second inclined surface 1301 at one end close to the limit strip 4 and at the top surface, and a plurality of protrusions 15 are fixedly provided on a surface of the limit groove 401 opposite to the limit block 13. Through this structure, the left enclosure 2 or the right enclosure 3 can only move upward in one direction relative to the limit strip 4, which is beneficial to maintaining the stability of the left enclosure 2 and the right enclosure 3 on the outside of the connecting pipe 7.

[0033] Refer again Figure 1-Figure 6 As shown, in order to clamp the left enclosure 2 and the right enclosure 3, in this scheme, an insertion rod 205 is fixedly provided at the convex strip on the left enclosure 2, and the top and bottom surfaces of the insertion rod 205 are provided with strip grooves, and a protrusion 14 is slidably provided in the strip groove, and the end of the protrusion 14 away from the insertion rod 205 is provided as a first inclined surface 1401, and a spring is fixedly provided between the inner end surface of the strip groove and the protrusion 14, and a through groove matching with the insertion rod 205 is provided at the convex strip on the right enclosure 3. When the left enclosure 2 and the right enclosure 3 are in contact with each other, the insertion rod 205 can pass through the through groove, and when the protrusion 14 passes over the convex strip on the right enclosure 3, the protrusion 14 can pop out, thereby locking the left enclosure 2 and the right enclosure 3.

[0034] Combination Figure 3-Figure 5 As shown, in order to drive the left enclosure 2 and the right enclosure 3 to move, the present scheme is provided with telescopic units on both sides of the top of the base 1, and the telescopic units can be cylinders or electric push rods, and the output end of the telescopic unit is connected to a push plate 5, and the push plate 5 is arranged as a U-shape.
