The function of the connector 6 is to install the hollow drill 7. Since the connector 6 is a technology well known to those skilled in the art, it will not be described in detail here. The lifting assembly includes a second motor 25, and the second motor 25 is fixedly installed on the U-shaped plate 3. On the upper end surface of the plate 3, the output end of the second motor 25 is fixedly connected with a lifting screw 26, and a lifting plate 27 is movably installed on the lifting screw 26. The mounting plate 4 is fixedly installed on the lifting plate 27. The internal thread on the lifting plate 27 is adapted to the external thread on the lifting screw 26. A limiting slider 28 is fixedly installed on the side end surface of the lifting plate 27. A limiting slide groove 29 is provided on the inner side surface of the U-shaped plate 3.

[0036] The U-shaped plate 3 is fixedly connected with a bracket plate 8, the bracket plate 8 is fixedly connected with a mounting shell 9, the mounting shell 9 is provided with a striking component and an adjusting component, and the striking force of the striking component is adjusted by the adjusting component;

[0037] The striking assembly includes two rotating grooves 10, two electric push rods 11 and a positioning block 12. The two rotating grooves 10 are symmetrically arranged on the inner top of the mounting shell 9. The rotating grooves 10 are rotatably connected with a rotating shaft 13 inside, and a striking plate 14 is fixedly connected to the rotating shaft 13. A spring 15 is fixedly installed on the side end surface of the striking plate 14. The positioning block 12 is fixedly installed on the inner top of the mounting shell 9 and is located on the outer side of the rotating groove 10. The angle of the striking plate 14 is limited by the positioning block 12. When the sliding block 19 is not provided in the technical solution, the end of the spring 15 away from the striking plate 14 can be fixedly connected to the inner side surface of the mounting shell 9.

[0038] Two electric push rods 11 are fixedly mounted on the upper end surface of the mounting shell 9, the output rod of the electric push rod 11 is fixedly connected to a fixing plate 16, the lower end surface of the fixing plate 16 is fixedly connected to a lower pressure plate 17, the bottom end of the lower pressure plate 17 penetrates the mounting shell 9 and contacts with the striking plate 14, through the rapid reciprocating lifting and lowering of the lower pressure plate 17, the striking plate 14 will hit the hollow drill 7 through the rebound force of the spring 15, the upper end surface of the mounting shell 9 and the upper end surface of the fixing plate 16 are both provided with through grooves, the notch diameter of the through groove is larger than the diameter of the hollow drill 7, to ensure that the hollow drill 7 can work normally.

[0039] In this embodiment, the electric push rod 11 in the knocking assembly drives the lower pressure plate 17 on the fixed plate 16 to rise and fall rapidly. The striking plate 14 that is pressed down by the lower pressure plate 17 and rotates will synchronously squeeze the spring 15. When the striking plate 14 is not pressed down by the lower pressure plate 17, the lower pressure plate 17 will hit the hollow drill 7 through the rebound force of the spring 15. The vibration force generated by the striking plate 14 facilitates the rapid discharge of the core in the hollow drill 7, avoids the core from being stuck in the hollow drill 7, and effectively improves the working efficiency and reliability of the core drilling rig.

[0040] For example 2, please refer to Figure 1-9 On the basis of the first embodiment, the adjustment component includes a sliding groove 18, which is arranged on the inner side of the mounting shell 9, and a sliding block 19 is slidably connected inside the sliding groove 18. One end of the spring 15 away from the striking plate 14 is fixedly connected to the sliding block 19, and the side end surface of the sliding block 19 is fixedly connected to a first bearing 20, and a threaded rod 21 is fixedly connected inside the first bearing 20. One end of the threaded rod 21 away from the first bearing 20 penetrates the mounting shell 9 and is fixedly connected to a turntable 22. By rotating the threaded rod 21, the elasticity of the spring 15 is adjusted by using the sliding block 19, and a limiting block 23 is fixedly installed on the sliding block 19. A limiting groove 24 is provided inside the sliding groove 18, and the limiting block 23 is slidably connected to the limiting groove 24. The limiting block 23 slides in the limiting groove 24 to ensure that the limiting slider 28 will not fall off from the sliding groove 18 due to the elastic force of the spring 15.

[0041] In this embodiment, by rotating the threaded rod 21 in the adjustment assembly, the sliding block 19 in the sliding groove 18 will move outward through the action of the first bearing 20, and the sliding block 19 will drive the spring 15 to extend outward while moving. Since the spring 15 is stretched, the elastic force of the spring 15 changes. After the elastic force of the spring 15 is adjusted, the force with which the striking plate 14 strikes the hollow drill 7 is changed, so that the core in the hollow drill 7 is discharged more quickly, while also avoiding the damage of the hollow drill 7 caused by the strong striking force, thereby improving the practicality of the device.

[0042] For example 3, please refer to Figure 1-9 On the basis of the first embodiment, a cleaning assembly is provided on the side end surface of the crawler chassis 1, and the soil on the surface of the hollow drill 7 is cleaned by the cleaning assembly. The cleaning assembly includes a support plate 30 and a horizontal frame plate 31. The support plate 30 is fixedly mounted on the inner side surface of the U-shaped plate 3. A second bearing 32 is fixedly mounted on the support plate 30. One end of the lifting screw 26 away from the second motor 25 is fixedly mounted inside the second bearing 32. A rotating rod 33 is fixedly mounted inside the second bearing 32. One end of the rotating rod 33 away from the second bearing 32 is fixedly mounted with a driving gear 34. A stabilizing plate is fixedly mounted on the crawler chassis 1. One end of the rotating rod 33 away from the second bearing 32 is rotatably connected to the stabilizing plate to ensure the stability of the driving gear 34 during rotation. An annular groove is provided on the inner side surface of the horizontal frame plate 31, and the stable rotation of the gear ring 37 is ensured by the annular groove. A connecting groove connected to the annular groove is provided on the outer side surface of the horizontal frame plate 31, and the connecting groove facilitates the engagement of the driving gear 34 with the gear ring 37.

[0043] The horizontal frame plate 31 is fixedly mounted on the side end surface of the crawler chassis 1 , a rotating ring 35 is rotatably mounted inside the horizontal frame plate 31 , a cleaning brush 36 is fixedly mounted inside the rotating ring 35 , a gear ring 37 is fixedly mounted on the outer side of the rotating ring 35 , and the driving gear 34 is meshed with the gear ring 37 .

[0044] In this embodiment, when the second motor 25 drives the lifting screw 26 to rise and fall, the lifting screw 26 will synchronously drive the driving gear 34 on the rotating rod 33 to rotate through the second bearing 32. Through the engagement of the driving gear 34 with the gear ring 37, the gear ring 37 will drive the rotating ring 35 to rotate in the horizontal frame plate 31. When the rotating ring 35 rotates, it will drive the cleaning brush 36 to clean the surface of the hollow drill 7, effectively preventing pollutants from affecting the rotation of the hollow drill 7 and affecting the removal and quality of the core. At the same time, when the hollow drill 7 is raised, it is convenient to clean the surface soil of the hollow drill 7 to avoid affecting the striking plate 14 from striking the hollow drill 7.

[0045] Working principle:

[0046] When in use, the second motor 25 drives the lifting screw 26 to rotate. When the lifting screw 26 rotates, the lifting plate 27 on the lifting screw 26 will slide in the limiting slide groove 29 through the limiting slider 28, and the lifting plate 27 will be in a descending state, and the first motor 5 is started synchronously, and the hollow drill 7 on the connector 6 is driven to rotate by the first motor 5, and the hollow drill 7 is used to complete the function of taking the core;

[0047] When the lifting screw 26 rotates, the lifting screw 26 drives the rotating rod 33 to rotate through the second bearing 32. The rotating rod 33 drives the driving gear 34 to rotate while rotating. Through the meshing of the driving gear 34 and the gear ring 37, the gear ring 37 drives the rotating ring 35 to rotate in the horizontal frame plate 31. When the rotating ring 35 rotates, it drives the cleaning brush 36 to clean the surface of the hollow drill 7, effectively preventing pollutants from affecting the rotation of the hollow drill 7 and affecting the removal and quality of the core. After the hollow drill 7 is raised, the rotatable cleaning brush 36 is used to clean the surface soil of the hollow drill 7;

[0048] When the core in the hollow drill 7 needs to be taken out, the electric push rod 11 drives the lower pressure plate 17 on the fixed plate 16 to quickly reciprocate and rise and fall, and the striking plate 14 that is rotated by the lower pressure plate 17 will synchronously squeeze the spring 15. When the striking plate 14 is not pressed down by the lower pressure plate 17, the lower pressure plate 17 will hit the hollow drill 7 through the rebound force of the spring 15. The vibration force generated by the striking plate 14 facilitates the rapid discharge of the core in the hollow drill 7 to prevent the core from being stuck in the hollow drill 7.

[0049] When the force of the knocking is small and the core in the hollow drill 7 cannot be discharged, the sliding block 19 in the sliding groove 18 will move outward through the action of the first bearing 20 by rotating the threaded rod 21. The sliding block 19 will drive the spring 15 to extend outward while moving. Since the spring 15 is stretched, the elastic force of the spring 15 changes. After the elastic force of the spring 15 is adjusted, the force of the striking plate 14 striking the hollow drill 7 is changed, so that the core in the hollow drill 7 is discharged more quickly, and at the same time, it is avoided that the knocking force is large, which may cause damage to the hollow drill 7.

[0050] When the striking force is large, the sliding block 19 can be moved inward by rotating the threaded rod 21 .

[0051] In the present technical solution, since the core drill uses a water spray mechanism when in use, the water spray can reduce the temperature of the borehole, keep the temperature inside the borehole within a suitable range, and avoid overheating and damage to the hollow drill 7. The water sprayed by the water spray mechanism can be sprayed on the cleaning brush 36 to facilitate cleaning of the cleaning brush 36. This effect can be set according to personnel needs. Since the water spray mechanism is a technology well known to people in this field, it will not be described in detail here.

[0052] The control method in this technical solution is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application document is mainly used to protect mechanical devices, so this technical solution no longer explains the motor control method and circuit connection relationship in detail.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
