[0002] Before the construction of a building project, it is necessary to sample and analyze the geology to be constructed in order to judge the geological conditions in advance, so as to facilitate the selection of appropriate construction equipment and the most appropriate construction technology during the construction process.

[0003] The commonly used soil sampling methods in the prior art are impact soil sampling and rotary soil sampling. Among them, rotary sampling generally requires water and will cause the soil to be disturbed, which is not effective for strict soil testing. Impact sampling does not use water, is disturbance-free, maintains the integrity of the soil sample, and has a more standardized soil testing effect. Therefore, general testing companies or units basically use impact soil sampling. The portable soil drilling rig widely used in the prior art is usually composed of a drill rod, a split sampling tube, an impact host, a puller and other accessories. The impact host drives the drill rod and the sampling tube into the predetermined depth underground, and the puller pulls out the sampling tube to complete the soil sampling.

[0004] However, the extractor in the above-mentioned prior art needs to be used independently of the impact host, and the extractor is usually large in size and weight, and needs to be manually operated, which can easily cause fatigue to the user, and has poor applicability.

DETAILED DESCRIPTION

[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0030] like Figures 1 to 8 As shown, the sampling device for building surveying and quality inspection provided by the present invention includes a body 1 and a clutch assembly 5. A prime mover 4 is fixed to the middle end of the top of the body 1, and the clutch assembly 5 is arranged at the middle end inside the body 1.

[0031] Specifically, the clutch assembly 5 includes a key sleeve 501, a clutch ratchet 502, a key shaft 503, a shift fork 504, a roller 505, a shift rod 506 and a damping shaft 507. The clutch ratchet 502 is coaxially fixed at the upper and lower ends of the key sleeve 501, and the key shaft 503 is slidably inserted inside the key sleeve 501, and the key shaft 503 is fixed to the output end of the prime mover 4. The shift fork 504 is clamped on the side of the key sleeve 501, and the opposite surface of the end of the shift fork 504 is rollingly matched with the middle area of ​​the key sleeve 501 through the roller 505. The shift fork 504 is externally connected to the shift rod 506, and the shift rod 506 extends to the outside of the body 1 through the side groove, and the shift rod 506 is rotationally matched with the side groove of the body 1 through the damping shaft 507.

[0032] The clutch assembly 5 can switch the power supply between the prime mover 4 and the pulling assembly 6 and the impact assembly 7, so that the present application only needs one prime mover 4 to meet the functional requirements of the user's impact operation in the sampling stage and the lifting operation in the sampling stage, making the functionality of the present application highly concentrated and improving applicability.

[0033] In some embodiments, a lifting assembly 6 is disposed at the upper end of the interior of the machine body 1 .

[0034] Specifically, the extraction assembly 6 includes a cone disk 601 and an upper ratchet disk 602. The cone disk 601 is rotatably mounted on the top of the body 1, and the upper ratchet disk 602 is coaxially fixed to the bottom of the cone disk 601. The upper ratchet disk 602 is engaged with the clutch ratchet disk 502 at the upper end of the key sleeve 501 for transmission. A through hole is opened in the middle of the upper ratchet disk 602 and penetrates to the cone disk 601. The inner diameter of the through hole in the middle of the upper ratchet disk 602 is greater than the outer diameter of the key shaft 503.

[0035] At the same time, the side of the cone disk 601 is meshed with an umbrella wheel 603, and the umbrella wheel 603 is rotatably installed inside a bearing seat 604 on a side wall of the body 1. The bearing seat 604 is connected to a shell 605, and a pull-out sleeve 606 is connected to the side of the rear end of the shell 605. The umbrella wheel 603 is coaxially connected to a transmission rod 607, and a ratchet 608 is coaxially fixed to the middle of the transmission rod 607. The ratchet teeth on the outer edge of the ratchet 608 cooperate with a pawl 609, and the pawl 609 is rotatably installed on the outside of the shell 605 through a spring. A gear 610 is coaxially fixed to the end of the transmission rod 607, and the outer edge teeth of the gear 610 extend to the inner cavity through the side wall of the pull-out sleeve 606.

[0036] Through the above arrangement, in the sampling stage of the present invention, the shift fork 504 is driven to lift upward by the shift rod 506. At this time, the power transmitted by the prime mover 4 through the key shaft 503 is transmitted to the cone disk 601 through the engagement of the clutch ratchet 502 at the upper end of the key sleeve 501 and the upper ratchet 602, and further to the transmission rod 607 through the engagement of the cone disk 601 and the side bevel wheel 603. The end of the transmission rod 607 is coaxially connected with a gear 610. The outer edge teeth of the gear 610 extend through the side wall of the pulling sleeve 606 to its inner cavity, and mesh with the connecting gear rod 803 inserted into the inner cavity of the pulling sleeve 606 for transmission, thereby pulling the split sampling tube 801 out of the ground to complete the sampling.

[0037] It should be noted that, during this process, the ratchet 608 coaxially disposed in the middle of the transmission rod 607 cooperates with the pawl 609 disposed on the outer edge of the ratchet, which can effectively prevent the connecting gear rod 803 from sliding and loosening due to the reversal of the gear 610, thereby ensuring the continuity of the extraction process of the connecting gear rod 803. The present application integrates the manual extractor that needs to be used independently in the prior art into the machine body 1, which not only eliminates the need for the user to manually operate the extractor to complete the extraction and sampling of the split sampling tube 801, but also simplifies the number of accessories of the sampler of the present application for easy carrying, reduces the fatigue of the operator in manual operations, and effectively improves the work efficiency of soil sampling operations.

[0038] See also Figures 3 to 8 The body 1 is fixed with two handles 2, and the bottom side of the body 1 is fixedly connected with a sleeve 3, and the lower end of the body 1 is provided with an impact assembly 7.

[0039] In some specific embodiments, the impact assembly 7 includes a cam 701 and a lower ratchet disc 702, the cam 701 is rotatably mounted at the bottom end of the body 1, and the lower ratchet disc 702 is coaxially fixed to the top of the cam 701, and the lower ratchet disc 702 is engaged with the clutch ratchet disc 502 at the lower end of the key sleeve 501 for transmission;

[0040] At the same time, a wobble plate 703 is clamped in the middle groove of the cam 701, and a connecting pin 704 is fixed to the outer edge of the annular structure of the wobble plate 703. The connecting pin 704 is clamped in the middle of the impact rod 705, and the impact rod 705 is located inside the connecting sleeve 3 and reciprocates axially. The tail of the impact rod 705 is slidably matched with a guide rod 706, and the guide rod 706 is fixedly installed on the inner wall of the other side of the body 1.

[0041] In addition, the present invention further has a sampling assembly 8 connected to the outside of the body 1 .

[0042] The sampling assembly 8 includes a split sampling tube 801, a threaded connector 802 and a connecting gear rod 803. The threaded connector 802 is threadedly fastened at both ends of the split sampling tube 801, and the threaded connector 802 at the upper end is externally connected to the connecting gear rod 803. The side wall tooth shape of the connecting gear rod 803 is meshed with the gear 610 for transmission, and the tail of the connecting gear rod 803 is in abutment with the impact rod 705.

[0043] The specific operation is as follows: in the preparation stage, the split sampling tube 801 is combined and the threaded connectors 802 are screwed on both ends of the split sampling tube 801, and then a connecting gear rod 803 of a suitable length is externally connected to the threaded connector 802 at the upper end of the split sampling tube 801, and finally the tail of the connecting gear rod 803 is inserted into the connecting sleeve 3 on the side of the bottom end of the body 1. In the sampling stage, the fork is driven downward by the lever 506. At this time, the power transmitted by the prime mover 4 through the key shaft 503 is transmitted through the clutch ratchet at the lower end of the key sleeve 501. The engagement of the disk 502 and the lower ratchet disk 702 transmits the rotation of the cam 701, and further generates opposite pressures on both sides through the oblique groove in the middle of the cam 701, converting the rotational motion of the cam 701 into the linear motion of the pendulum disk 703, and then driving the impact rod 705 to make axial reciprocating motion through the connecting pin 704 at the end of the pendulum disk 703, and then applying a continuous impact force to the tail of the connecting gear rod 803 through the impact rod 705, so as to drive the split sampling tube 801 into the predetermined depth underground to complete soil sampling.

[0044] It should be noted that, in the present application, the rotational power output by the prime mover 4 is converted into a high-speed reciprocating impact force of the impact rod 705 through the setting of the impact assembly 7, thereby providing a continuous impact force for the sampling operation of the split sampling tube 801. No water is required during the entire process, and the disturbance to the soil can be minimized, thereby effectively maintaining the integrity of the soil sample.

[0045] In summary, the sampling device for building surveying and mapping quality inspection is used in the following ways:

[0046] In the preparation stage, the split sampling tubes 801 are combined and then threaded connectors 802 are screwed on both ends thereof, and then a connecting gear rod 803 of a suitable length is externally connected to the threaded connector 802 located at the upper end of the split sampling tubes 801, and finally the tail of the connecting gear rod 803 is inserted into the connecting sleeve 3 on the side of the bottom end of the body 1. In the sampling stage, the fork is driven downward by the lever 506. At this time, the power transmitted by the prime mover 4 through the key shaft 503 is transmitted to the cam 701 through the engagement of the clutch ratchet 502 at the lower end of the key sleeve 501 and the lower ratchet 702 to rotate the cam 701, and further opposite pressures are generated on both sides through the oblique groove in the middle of the cam 701, so that the rotational motion of the cam 701 is converted into the linear motion of the swing plate 703, and then the impact rod 705 is driven to make axial reciprocating motion through the connecting pin 704 at the end of the swing plate 703, and then the impact rod 705 applies a continuous impact force to the tail of the connecting gear rod 803, so that the split sampling tube 801 is driven into the predetermined depth underground to complete soil sampling;

[0047] During the sampling phase, the shift fork 504 is lifted upward by the shift rod 506. At this time, the power transmitted by the prime mover 4 through the key shaft 503 is transmitted to the cone disk 601 through the engagement of the clutch ratchet 502 at the upper end of the key sleeve 501 and the upper ratchet 602, and further to the transmission rod 607 through the engagement of the cone disk 601 and the side bevel wheel 603. The transmission rod 607 is coaxially connected to the end of the transmission rod 607. The outer edge teeth of the gear 610 extend through the side wall of the extraction sleeve 606 to its inner cavity, and mesh with the connecting gear rod 803 inserted into the inner cavity of the extraction sleeve 606 for transmission, thereby pulling the split sampling tube 801 out of the ground. The sampling is completed; during this process, the ratchet 608 coaxially disposed in the middle of the transmission rod 607 cooperates with the pawl 609 disposed on the outer edge of the ratchet, which can effectively prevent the connecting gear rod 803 from sliding and loosening due to the reversal of the gear 610, thereby ensuring the continuity of the pulling-out process of the connecting gear rod 803. The present application integrates the manual puller that needs to be used independently in the prior art into the machine body 1, which not only eliminates the need for the user to manually operate the puller to complete the pulling-out and sampling of the split sampling tube 801, but also simplifies the number of accessories of the sampler of the present application for easy carrying, reduces the fatigue of the operator's manual operation, and effectively improves the work efficiency of the soil sampling operation.
