Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a geological prospecting sampling device. Background Art

[0002] The commonly used methods of geological exploration are drilling, pit exploration and geophysical exploration. Since drilling is not restricted by terrain and geological conditions and has high exploration accuracy and efficiency, it is the most widely used exploration method in geological exploration, which helps explorers to quickly and reliably understand geological data.

[0003] At present, in drilling operations, vertical backpack drilling rigs are widely used. Vertical backpack drilling rigs mainly include drilling rigs, corers and frames. By lifting and lowering the drilling rig on the frame, the drilling process of the drilling rig can be made more stable.

[0004] Existing vertical backpack drilling rigs rarely have casters installed on their frames. When the entire machine is to be moved, it can only be moved by at least two operators using manual lifting. Some vertical backpack drilling rigs equipped with casters are usually designed to have very small casters to prevent the casters from affecting the flatness of the frame base and to ensure the contact area between the base and the ground. The brackets of such casters are usually fixed to the base of the frame, and the use status of the casters cannot be adjusted. When the frame needs to be pulled, the operator needs to tilt the frame significantly to make the casters contact the ground, but the problem this brings is that it is inconvenient for the operator to pull or push the frame.

[0005] Therefore, how to adjust the use status of large-size casters so as not to affect the support stability of the frame base and improve the convenience of transferring the whole machine is an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0039] like Figure 1-11 As shown, in one embodiment of the utility model, a geological exploration sampling device is provided, including a base 10, a support column 20, a drilling rig body 30 and two caster mechanisms 40, the support column 20 is detachably mounted on the base 10, and a lifting seat 21 is provided on the support column 20 for lifting. The drilling rig body 30 is detachably mounted on the lifting seat 21, and a corer 31 is installed on the drilling rig body 30.

[0040] Two caster mechanisms 40 are arranged on both sides of the base 10, respectively. The caster mechanism 40 includes a caster body 41, a connecting portion 42 and a locking assembly 43. The caster body 41 is rotatably arranged on the connecting portion 42, and the connecting portion 42 is rotatably arranged on the base 10. The rotation axis 423 line of the connecting portion 42 is parallel to the rotation axis 423 line of the caster body 41. The connecting portion 42 is provided with a first locking hole 421 and a second locking hole 422. The locking assembly 43 can be inserted into the first locking hole 421 or the second locking hole 422 to limit the rotation of the connecting portion 42. When the locking assembly 43 is inserted into the first locking hole 421, the lowest point of the caster body 41 is higher than the plane where the bottom surface of the base 10 is located. When the locking assembly 43 is inserted into the second locking hole 422, the lowest point of the caster body 41 is lower than the plane where the bottom surface of the base 10 is located.

[0041] When performing sampling operations, the operator inserts the locking assembly 43 into the first locking hole 421, and the connecting portion 42 will be locked. At this time, since the lowest point of the caster body 41 is higher than the plane where the bottom surface of the base 10 is located, the caster body 41 will not affect or interfere with the contact between the base 10 and the ground, thereby ensuring the contact area between the base 10 and the ground and improving the stability of the device during drilling.

[0042] When the sampling device needs to be transferred, the operator inserts the locking assembly 43 into the second locking hole 422, and the connecting portion 42 will be locked. At this time, since the lowest point of the caster body 41 is lower than the plane where the bottom surface of the base 10 is located, the operator can easily transfer the sampling device by tilting and pulling the sampling device.

[0043] In summary, the geological exploration sampling device provided in this embodiment is configured to rotate the connection part 42 on the base 10 and use the locking assembly 43 to lock the connection part 42, so that the operator can adjust and lock the position of the caster body 41 according to different usage requirements. During the drilling process, the base 10 can ensure the supporting and stabilizing effect of the support column 20 and the drilling rig body 30, and the operator can also transfer the sampling device conveniently. The overall structural design of the sampling device is reasonable, the operation is convenient, and it is suitable for promotion.

[0044] See also Figure 4-6 In one embodiment, the locking assembly 43 includes a mounting seat 431, a locking rod 432 and a reset member 433. The mounting seat 431 is fixed on the base 10. The locking rod 432 is movably arranged on the mounting seat 431. The axis of the locking rod 432 is parallel to the rotation axis 423 of the connecting portion 42. Both ends of the locking rod 432 extend out of the mounting seat 431 respectively. The locking rod 432 can be plugged into the first locking hole 421 or the second locking hole 422 respectively. The reset member 433 is used to apply elastic force to the locking rod 432 to prevent the locking rod 432 from withdrawing from the first locking hole 421 or the second locking hole 422.

[0045] When the use state of the caster body 41 needs to be adjusted, the operator first pulls the locking rod 432 to release the restriction on the connecting portion 42, then rotates the connecting portion 42 to adjust the position of the caster body 41, and finally reinserts the locking rod 432 into the first locking hole 421 or the second locking hole 422. Since the reset member 433 always applies elastic force to the locking rod 432, the locking rod 432 will not easily withdraw from the first locking hole 421 or the second locking hole 422 under the action of the reset member 433, thereby improving the locking effect of the connecting portion 42 and the caster body 41.

[0046] Furthermore, a mounting cavity is provided in the mounting seat 431, and the locking rod 432 passes through the mounting cavity. A flange 434 is provided on the rod body of the locking rod 432 located in the mounting cavity, and the flange 434 abuts against the cavity wall of the mounting cavity on the side close to the caster body 41. The reset member 433 is sleeved outside the locking rod 432 and located in the mounting cavity, and the two ends of the reset member 433 abut against the cavity wall of the mounting cavity and the flange 434 respectively. Among them, the reset member 433 uses a compression spring. In the process of the locking rod 432 withdrawing from the first locking hole 421 or the second locking hole 422, the flange 434 will cooperate with the cavity wall of the mounting cavity to further compress the reset member 433. When the locking rod 432 is inserted into the first locking hole 421 or the second locking hole 422, the reset member 433 will continue to apply elastic force to the flange 434, so that the locking rod 432 will not easily withdraw from the first locking hole 421 or the second locking hole 422.

[0047] In one embodiment, in order to facilitate the operator to operate the locking rod 432 , one end of the locking rod 432 away from the caster body 41 is bent to form a handle 435 .

[0048] See also Figure 4 In one embodiment, the connecting portion 42 includes a rotating shaft 423, a first swing arm 424, a second swing arm 425 and a supporting shaft 426. The rotating shaft 423 is rotatably arranged on the base 10. The first swing arm 424 is respectively connected to the rotating shaft 423, the second swing arm 425 and the supporting shaft 426. The first locking hole 421 is arranged on the first swing arm 424, the second locking hole 422 is arranged on the second swing arm 425, and the caster body 41 is rotatably arranged on the supporting shaft 426. The first swing arm 424 and the second swing arm 425 are arranged at an angle of 90°. The operator can align the locking rod 432 with the first locking hole 421 or the second locking hole 422 by rotating the rotating shaft 423. Of course, before inserting the locking rod 432 into the second locking hole 422, the operator needs to tilt the base 10 slightly toward the other side to make way for the caster body 41.

[0049] In one embodiment, the base 10 includes a first base body 11 and a second base body 12 , the second base body 12 is telescopically fitted on the first base body 11 , two caster mechanisms 40 are respectively disposed on the first base body 11 and the second base body 12 , and the support column 20 is disposed on the first base body 11 .

[0050] Specifically, the first base body 11 includes two first mounting tubes 111 arranged in parallel, and a plurality of first connecting arms 112 are provided between the two first mounting tubes 111; the second base body 12 includes two second mounting tubes 121 arranged in parallel, and at least one second connecting arm 122 is provided between the two second mounting tubes 121. The first mounting tube 111 and the second mounting tube 121 are both in a structure with one end closed and the other end open, and each second mounting tube 121 is movably inserted into a corresponding first mounting tube 111. The base 10 also includes two locking bolts 13, each locking bolt 13 is threadedly engaged with a corresponding first mounting tube 111, and the locking bolt 13 can tighten the second mounting tube 121.

[0051] By designing the base 10 as a split structure, after the second mounting tube 121 is pulled out of the first mounting tube 111, the contact area between the base 10 and the ground is further increased, so that it is convenient for the operator to step on the first base body 11 and the second base body 12 with his feet, thereby improving the stability of the device during drilling. At the same time, after use, the second mounting tube 121 can be re-stored into the first mounting tube 111, thereby reducing the space occupied by the base 10, thereby facilitating the storage of the sampling device.

[0052] In one embodiment, two adjustment rods 22 are provided on the support column 20, and the two adjustment rods 22 are respectively arranged on both sides of the support column 20. Fig.10 The operator can not only adjust the lifting position of the lifting seat 21 by operating the adjusting rod 22, but also use the two adjusting rods 22 to pull or push the sampling device when transferring the sampling device. The lifting and lowering action of the lifting seat 21 driven by the adjusting rod 22 is a prior art and will not be described in detail in this example.

[0053] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
