[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] A core receiving device for drilling engineering, comprising a drilling vehicle body 1, an auxiliary receiving mechanism 6 is provided on the front of the drilling vehicle body 1, the auxiliary receiving mechanism 6 comprises a connecting plate 601, a transmission plate 602, a knocking plate 603, a fixing rod 604, a motor 1 605, a limiting rod 606, a limiting support 607, a mounting groove 608, a coil spring 609, a sliding extrusion plate 610, a mounting base 611, a support plate 612, a reset spring 613 and a rotating plate 614, the top of the motor 1 605 is fixedly connected to the connecting plate 601, the top of the connecting plate 601 is fixedly connected to the connecting rod 4, the output end of the motor 1 605 is fixedly connected to the rotating plate 614, the bottom end of the rotating plate 614 is rotatably connected to the top of the mounting base 611, and the bottom end of the mounting base 611 is fixedly connected to the receiving device body 5.

[0033] Preferably, the front of the drilling vehicle body 1 is fixedly connected to the limited track 2, the front of the limited track 2 is vertically slidably connected to the sliding support 3, the bottom end of the sliding support 3 is fixedly connected to the motor 2 7, the connecting rod 4 is fixedly connected to the output end of the motor 2 7, the bottom end of the connecting plate 601 is fixedly connected to a plurality of fixed rods 604, and the bottom ends of the plurality of fixed rods 604 are all fixedly connected to the top of the mounting base 611. In the actual implementation process, the sliding support 3 can move freely in the limited track 2, so as to realize the precise adjustment of the position of the docking device body 5, and the sliding support 3 can be quickly and stably moved to a suitable position so that the docking device body 5 can be accurately aligned with the core, thereby improving the efficiency and accuracy of the docking.

[0034] Preferably, the top of the mounting base 611 is fixedly connected with a plurality of position-limiting supports 607, the middle of the plurality of position-limiting supports 607 are slidably connected with a sliding extrusion plate 610, the tops of the plurality of sliding extrusion plates 610 are fixedly connected with a support plate 612, the inner sides of the plurality of support plates 612 are fixedly connected with two return springs 613, and one end of two adjacent return springs 613 is fixedly connected to the inner side of the position-limiting support 607. In the actual implementation process, the setting of the return spring 613 not only enhances the stability of the sliding extrusion plate 610, but also effectively prevents displacement caused by external force, thereby ensuring the accuracy and reliability of the receiving process, and when the sliding extrusion plate 610 is no longer squeezed by the rotating plate 614, the return spring 613 can drive the sliding extrusion plate 610 to reset so as to facilitate the next squeezing of the rotating plate 614.

[0035] Preferably, the bottom ends of the plurality of sliding extrusion plates 610 are all slidably connected to the top end of the mounting base 611, the outer wall of the mounting base 611 is fixedly connected with a plurality of limiting rods 606, the middle parts of the plurality of limiting rods 606 are all rotatably connected with the transmission plate 602, and the middle parts of the plurality of transmission plates 602 are all provided with mounting grooves 608. In actual implementation, the plurality of limiting rods 606 can limit the transmission plate 602, and the mounting grooves 608 can facilitate the installation of the coil spring 609.

[0036] Preferably, the middle parts of the plurality of limit rods 606 are sleeved with coil springs 609, one end of the plurality of coil springs 609 is respectively fixedly connected to the outer wall of the limit rods 606, and the other end of the plurality of coil springs 609 is respectively fixedly connected to the inner wall of the mounting slot 608. In the actual implementation process, the coil spring 609 can drive the transmission plate 602 to reset, so that the sliding extrusion plate 610 can always extrude the transmission plate 602.

[0037] Preferably, the bottom ends of the plurality of transmission plates 602 are fixedly connected with a knocking plate 603, and the inner sides of the plurality of knocking plates 603 are all in contact with the outer wall of the receiving device body 5. In the actual implementation process, the setting of the knocking plate 603 promotes the falling off of the core by repeated slight knocking, which can not only effectively reduce the damage to the core, but also reduce the wear of the receiving device body 5, thereby extending the service life of the equipment.

[0038] A core receiving method for drilling engineering comprises the following steps:

[0039] S1: Equipment preparation, moving the drilling vehicle body 1 to the drilling site, and ensuring that the mounting base 611 of the receiving device body 5 is firmly fixed to the ground. This step ensures the safety and stability of the equipment and provides a solid foundation for subsequent core receiving;

[0040] S2: limit adjustment, adjust the position of the sliding support 3, align the limit track 2 with the core detection position, and ensure that the receiving device body 5 is facing the core. This step ensures that the receiving device body 5 is facing the core, reduces the error in the receiving process, and improves the success rate of core receiving;

[0041] S3: Auxiliary access, when the core enters the receiving device body 5, the auxiliary access mechanism 6 is started through the cooperation of the motor 1 605 and the transmission plate 602, and the knocking plate 603 of the auxiliary access mechanism 6 contacts the receiving device body 5, and the core is forced to separate from the inner wall of the receiving device body 5 by slightly knocking the receiving device body 5, thereby completing the core access. This step causes the core to separate from the inner wall of the receiving device body 5 by slightly knocking, avoiding damage to the core and improving the efficiency of access. The correct knocking force and frequency can also effectively prevent the wear of the receiving device and extend the service life of the equipment.

[0042] During operation, the drilling vehicle body 1 is moved to the drilling site, and the receiving device body 5 is firmly fixed on the ground through the limit support 607, ready for receiving the core. After the equipment is installed securely, the sliding support 3 is driven by the motor 2 7 to slide up and down on the limit track 2. The sliding support 3 is connected to the receiving device body 5, thereby ensuring that the limit track 2 of the receiving device body 5 is accurately aligned with the drilling core position. This adjustment process ensures that the receiving device body 5 can accurately align with the core position to be received after drilling is completed. When drilling is completed and the core enters the receiving device body 5, the motor 605 starts to work and drives the rotating plate 614 to rotate. The side wall of the rotating plate 614 is uneven. When the rotating plate 614 rotates, it can squeeze multiple sliding squeezing plates 610 in turn to move. One end of the multiple sliding squeezing plates 610 squeezes the corresponding transmission plates 602 respectively. When the transmission plate 602 is squeezed, the transmission plate 602 drives the knocking plate 603 to knock on the outer wall of the receiving device body 5, and the core is forced to detach from the inner wall of the receiving device body 5. Mechanical grasping is not used to avoid damage to the core, thereby effectively ensuring the smooth progress of the core receiving process and ensuring the integrity and receiving efficiency of the core.

[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the application should be included in the protection scope of the present application.
