Description

TECHNICAL FIELD

[0001] The utility model relates to the field of geological exploration, and concretely relates to a rock debris sampler for geological exploration. BACKGROUND

[0002] The rock debris sampler is a tool specially used for collecting rock debris samples from rocks, soil or other solid substances. The rotary rock debris sampler drills into the target material through a rotating spiral drill bit and collects the rock debris samples into the drill bit or a special collection container while rotating. This method can effectively collect rock debris samples at different depths with less disturbance to the surrounding environment. The spiral rock debris sampler is widely used in the fields of geological exploration, mineral resource investigation, geotechnical engineering and environmental monitoring.

[0003] In the prior art, the Chinese utility model patent with publication number CN223259311U discloses a rock debris sampler for geological exploration. The stability of the sampler during movement can be effectively ensured through the cooperation of the sleeve column and the support. However, during actual use, the sampler produces continuous vibration during operation, and the load generated thereby is highly concentrated at the welding points of the support and the mounting member. This stress concentration effect makes it easy for cracks to occur at the connection and gradually expand after long-term use, eventually leading to fatigue fracture. Moreover, when subjected to lateral impact or uneven load, the stress is completely concentrated on a single support leg, greatly increasing the risk of damage and reducing stability. In view of this, we propose a rock debris sampler for geological exploration to solve the above problems. SUMMARY

[0004] The utility model aims to solve the problem of poor stability of some rock debris samplers for geological exploration.

[0005] To achieve the above utility model purposes and improve the above problems, the utility model provides a rock debris sampler for geological exploration, which comprises a sampler body, a connecting sleeve movably arranged outside the sampler body, a fixing ring fixedly arranged outside the connecting sleeve, eight fixing plates fixedly connected to the surface of the fixing ring, a support shaft rotatably connected between every two adjacent fixing plates, a support leg fixedly arranged outside the support shaft, a torsional spring fixedly connected between the support leg and the fixing plate, the torsional spring movably arranged outside the support shaft, a sliding ring slidably arranged outside the connecting sleeve, a first connecting member fixedly connected to the outside of the sliding ring, a second connecting member fixedly connected to the surface of the support leg, a cross plate rotatably connected between the first connecting member and the second connecting member through a shaft body, and a storage assembly arranged outside the connecting sleeve.

[0007] As a preferred technical scheme of the present application, the receiving assembly comprises a receiving cover, the receiving cover movably sleeves the outside of the connecting sleeve, and the upper surface of the receiving cover is rotatably connected with a rotating ring.

[0008] As a preferred technical scheme of the present application, a threaded groove is formed in the surface of the connecting sleeve, and the rotating ring is threadedly sleeved outside the connecting sleeve through the threaded groove.

[0009] As a preferred technical scheme of the present application, four limiting rods are fixedly connected in the inside of the receiving cover, and the four limiting rods all slidably penetrate through the lower surface of the fixed ring.

[0010] As a preferred technical scheme of the present application, a connecting plate is fixedly connected at the end of the supporting leg away from the fixed plate, and an inserting rod is movably sleeved in the inside of the connecting plate.

[0011] As a preferred technical scheme of the present application, a resisting plate is fixedly connected to the lower surface of the connecting plate, and an extending groove is formed in the inside of the resisting plate.

[0012] As a preferred technical scheme of the present application, a supporting plate is fixedly connected to the lower surface of the connecting plate, a locking rod is slidably sleeved in the inside of the supporting plate, two inserting grooves which are in communication with the outside are formed in the inside of the inserting rod, the inserting grooves are matched with the locking rod, a reset spring is movably sleeved to the outside of the locking rod, one end of the reset spring is fixedly connected with the locking rod, and the other end of the reset spring is fixedly connected with the supporting plate.

[0016] 2. Through the cooperation between the set storage cover, the push ring, the support shaft and the torsional spring and other structures, the storage cover can be driven to move up and down by rotating the push ring, so as to complete the switching between the two states of the support leg gathering and storing and the support leg opening and supporting, thereby significantly reducing the volume of the device when it is not working, facilitating transportation and storage, and improving the portability and operation efficiency of field exploration.

[0040] Further, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 As shown, the lower surface of the connecting plate 21 is fixedly connected with a supporting plate 18 for connection, the inside of the supporting plate 18 slidably sheaths a locking rod 19 for locking the position of the insertion rod 23, the inside of the insertion rod 23 is provided with two insertion grooves 25 in communication with the outside, the insertion grooves 25 are matched with the locking rod 19, the outside of the locking rod 19 movably sheaths a return spring 20, one end of the return spring 20 is fixedly connected with the locking rod 19, the other end of the return spring 20 is fixedly connected with the supporting plate 18, when the staff needs to switch the fixing mode of the device as a whole, the locking rod 19 is slid in the inside of the supporting plate 18 by pulling it outward, at this time the return spring 20 will deform correspondingly, and the movement of the insertion rod 23 can be realized when the locking rod 19 is separated from the insertion groove 25.

[0041] The use process of the rock debris sampler for geological exploration is as follows:

[0042] When the device needs to be used, first, the rotating ring 15 is rotated, at this time, under the action of the threaded groove 16, the storage cover 14 will move upwards outside the connecting sleeve 2, at this time, the storage cover 14 will gradually separate from the supporting leg 6, and then under the action of the torsional spring 7, the supporting leg 6 will be opened, and through the rotation of the supporting leg 6, the movement of the second connecting piece 10 can be driven, and because the length of the horizontal plate 11 is fixed, under the action of the first connecting piece 9, the sliding ring 8 will slide outside the connecting sleeve 2, until the limiting block 13 slides to the uppermost side inside the limiting through groove 12, at this time, the supporting leg 6 will also be opened to the maximum angle, and then the device as a whole can be supported by means of the inclined supporting leg 6, when subjected to a shock load, the four supporting legs 6 will continue to open outward, but under the action of the horizontal plate 11, the supporting leg 6 can be effectively limited, thereby achieving the purpose of offsetting the lateral load, ensuring the supporting effect of the supporting leg 6 and improving the stability of the support.

[0043] In addition, when storage, the rotating ring 15 is rotated by the staff, and under the cooperation of the threaded groove 16, the storage cover 14 is moved, when the storage cover 14 descends to contact the supporting leg 6, at this time, the storage cover 14 continues to descend, thereby the four groups of supporting legs 6 are pressed to the middle, until the four groups of supporting legs 6 are close to the outside of the connecting sleeve 2, finally the storage of the four groups of supporting legs 6 is realized, thereby reducing the volume of the device as a whole, improving the portability, and the sliding ring 8 also descends under the action of gravity, driving the first connecting piece 9 to descend, thereby realizing the reset of the sliding ring 8.
