[0035] To make the objectives, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below in conjunction with embodiments and drawings. The illustrative embodiments and descriptions thereof of the present utility model are only used to explain the present utility model and shall not be construed as limiting the present utility model.

[0036] Embodiment

[0037] As Figures 1 to 7 shown, the present utility model includes a sleeve body and a rotating rod 1 disposed inside the sleeve body. A screw conveyor 2 is disposed on the outer wall of the rotating rod 1. An outlet 20 and a housing 5 are further provided on the side wall of the sleeve body. The housing 5 is detachably connected to the sleeve body. An opening is provided on one side of the housing 5. A collecting pipe 15 is further provided inside the opening. A push rod 12 is further provided on the housing 5. The push rod 12 is used to push the collecting pipe 15 to be connected to the outlet 20, and the push rod 12 is also used to discharge the sample collected in the collecting pipe 15.

[0038] In view of the prior art that when collecting loose physical property samples (such as soil), traditional collecting devices usually consist of a sleeve, a rotating rod and a screw conveyor. The upper end of the sleeve is a closed structure. The rotating rod is threadedly connected to the closed end of the sleeve. The screw conveyor is distributed on the outer wall of the rotating rod located inside the sleeve. At the same time, a handle for rotating the rotating rod is provided on the rotating rod. During use, the rotating rod inside the sleeve is rotated by using the handle, so that the conical structure at the bottom of the rotating rod drills holes in the soil. During the process of the rotating rod drilling holes in the soil, the screw conveyor is used to convey the soil scattered by the drilling to the inside of the sleeve. Finally, the soil to be collected is stored in the gap between the sleeve and the screw conveyor. However, this makes it inconvenient to quickly take out the soil stored in the sleeve subsequently. Therefore, in this technical solution, an outlet 20 is provided on the side wall of the existing sleeve body, and a housing 5 is further provided on the side wall of the sleeve body. The housing 5 can be detachably connected to the sleeve body, which is convenient for quickly removing the housing 5 from the sleeve body. At the same time, a collecting pipe 15 is further provided inside the opening on one side of the housing 5. The push rod 12 provided on the housing 5 can be used to push the collecting pipe 15 to be inserted into the outlet 20 of the sleeve body. In this way, when collecting soil, after the screw conveyor 2 conveys the soil into the sleeve body, finally the soil can be conveyed into the collecting pipe 15 through the outlet 20 on the side wall of the sleeve body, and the collected soil is stored in the collecting pipe 15. When the collection of soil is completed, the housing 5 is removed from the sleeve body, and then the provided push rod 12 is inserted into the collecting pipe 15 to push out the soil stored in the collecting pipe 15, thereby achieving the purpose of quickly discharging the collected soil.

[0039] The sleeve body includes a round pipe 4 and a square pipe 6. The round pipe 4 is welded to the square pipe 6. The outlet 20 is located on the side wall of the square pipe 6. The housing 5 is detachably connected to the side wall of the square pipe 6.

[0040] Since the sleeve body needs to be detachably connected to the housing 5, in order to ensure that there is an installation position for the sleeve body on the housing 5, the sleeve body provided in this embodiment is divided into two parts. The upper part is a square tube 6, and the lower part is a round tube 4. The lower end of the square tube 6 is welded to the upper end of the round tube 4, and the square tube 6 and the round tube 4 are in communication with each other. In this way, the rotating rod 1 and the auger 2 are mostly located inside the round tube 4, and the housing 5 is detachably connected to the side wall of the square tube 6.

[0041] A notch 22 is further provided on the side wall of the square tube 6, and the notch 22 communicates with the top of the square tube 6; the outlet 20 communicates with the notch 22; a sliding groove 23 is further provided on the inner wall of the notch 22, and the sliding groove 23 also communicates with the top of the square tube 6. A sliding block 24 matching the sliding groove 23 is provided on the side wall of the housing 5. A part of the housing 5 is located inside the notch 22, and the sliding block 24 is located inside the sliding groove 23.

[0042] In this embodiment, in order to achieve the detachable connection between the housing 5 and the square tube 6, a notch 22 is further provided on the side of the square tube 6 where the outlet 20 is provided, a sliding groove 23 is provided on the inner wall of the notch 22, and a sliding block 24 is provided on the side wall of the housing 5. During installation, the open end of the housing 5 is placed above the notch 22, then the sliding block 24 on the housing 5 is inserted into the sliding groove 23, and the housing 5 is moved downward until the housing 5 reaches the lowermost end of the notch 22. At this time, the collection tube 15 provided in the housing 5 is exactly aligned with the outlet 20 on the sleeve body. Finally, the push rod 12 is used to push the collection tube 15 in the housing 5 to move, and finally the collection tube 15 is communicated with the outlet 20. In this way, the soil in the sleeve body can enter the collection tube 15 through the outlet 20, achieving the purpose of storing the soil in the collection tube 15.

[0043] Among them, the outer diameter of the provided collection tube 15 is the same as the inner diameter of the outlet 20. In this way, the provided sliding block 24 and the sliding groove 23 can limit the movement of the housing 5 in the radial direction of the sleeve assembly. When the push rod 12 moves the collection tube 15 into the outlet 20, on the one hand, the communication between the collection tube 15 and the outlet 20 can be achieved, and on the other hand, the provided collection tube 15 can limit the movement of the housing 5 in the axial direction of the sleeve assembly, thereby stably fixing the housing 5 on the square tube 6.

[0044] The push rod 12 is also provided with a groove on the side wall inside the housing 5. An elastic member 17 and a limit ball 16 are arranged in the groove. One end of the elastic member 17 is connected to the inner bottom of the groove, and the other end is connected to the limit ball 16. The elastic member 17 is used to push the limit ball 16 to protrude outside the push rod 12. The end of the collection tube 15 facing the push rod 12 is a closed structure, and a through hole with an inner diameter consistent with the outer diameter of the push rod 12 is provided on the closed end of the collection tube 15.

[0045] In this embodiment, in order to ensure that the provided push rod 12 can not only push the collection tube 15 inside the housing 5 to move, realize the communication between the collection tube 15 and the outlet 20, but also realize the discharge of the soil stored in the collection tube 15. Therefore, an elastic member 17 and a limit ball 16 are arranged on the side wall of the push rod 12. The provided elastic member 17 is a spring, and the maximum elastic force of the elastic member 17 is to push a part of the limit ball 16 to protrude outside the push rod 12. In this way, when the push rod 12 is pushed to move, the limit ball 16 on the side wall of the push rod 12 forces the collection tube 15 to move along with the push rod 12, so as to smoothly insert the collection tube 15 into the outlet 20. After the soil is collected, when the housing 5 is removed from the square tube 6, the end of the collection tube 15 is restricted, and then the push rod 12 is continued to be pushed. When the push rod 12 moves in the direction of the collection tube 15, the collection tube 15 squeezes the limit ball 16 protruding outside the push rod 12, retracting the limit ball 16 into the groove, so as to ensure that the push rod 12 enters the collection tube 15 through the through hole of the collection tube 15. As the push rod 12 continues to move, the soil stored in the collection tube 15 can be discharged.

[0046] An active disk 18 with an outer diameter consistent with the inner diameter of the collection tube 15 is still arranged inside the collection tube 15; the push rod 12 is connected to the active disk 18.

[0047] In this embodiment, in order to effectively discharge the soil stored in the collection tube 15, an active disk 18 is also arranged inside the collection tube 15, and the push rod 12 is used to push the active disk 18 to move inside the collection tube 15, so as to effectively discharge the soil stored in the collection tube 15.

[0048] At the same time, when the housing 5 is removed from the square tube 6, in order to ensure that the collection tube 15 extending into the outlet 20 can quickly retract back, the push rod 12 is connected to the active disk 18. In this way, when the push rod 12 is driven to move back, the push rod 12 pulls the active disk 18 to move together, so as to pull the collection tube 15 to quickly remove from the outlet 20.

[0049] In order to prevent the collection tube 15 from automatically removing from the outlet 20 during the soil collection process, in another embodiment, the provided push rod 12 is connected to the housing 5 by a thread.

[0050] A limiting groove is provided on the inner wall of the housing 5, and a limiting block 14 located in the limiting groove is further provided on the side wall of the collecting pipe 15.

[0051] In this embodiment, in order to facilitate the smooth discharge of the soil stored in the collecting pipe 15, a limiting groove is further provided on the inner wall of the housing 5, and a limiting block 14 located in the limiting groove is provided on the outer wall of the collecting pipe 15. In this way, when the limiting block 14 on the side wall of the collecting pipe 15 moves to the maximum displacement at one end of the limiting groove, the end of the collecting pipe 15 just extends out of the opening of the housing 5 and is inserted into the outlet 20; when the housing 5 is removed from the square pipe 6 after the soil collection is completed, during the process of moving the push rod 12 to discharge the soil stored in the collecting pipe 15, when the push rod 12 pushes the limiting block 14 on the collecting pipe 15 to move to the maximum displacement at one end of the limiting groove, when the push rod 12 continues to move, the collecting pipe 15 can no longer displace at this time. Therefore, during the movement of the push rod 12, the collecting pipe 15 can squeeze the limiting ball 16 on the outer wall of the push rod 12, so as to ensure that the push rod 12 can smoothly displace relative to the collecting pipe 15 and push the movable disk 18 in the collecting pipe 15 to discharge the soil smoothly.

[0052] After the soil in the collecting pipe 15 is discharged, move the push rod 12 back. The push rod 12 will pull the collecting pipe 15 to move back synchronously. When the limiting block 14 on the collecting pipe 15 retracts to the maximum displacement at the other end of the limiting groove, the collecting pipe 15 can no longer move synchronously with the push rod 12. When the push rod 12 continues to retract, it will force the collecting pipe 15 to squeeze the limiting ball 16 again, so that the limiting ball 16 on the push rod 12 moves out of the collecting pipe 15.

[0053] A bearing 21 is further provided in the square pipe 6, and a movable rod 9 with an outer diameter matching the inner diameter of the bearing 21 is provided in the bearing 21; a connecting hole is provided on the movable rod 9, a vertical rod 10 is provided in the connecting hole, the vertical rod 10 is connected to the connecting hole by a thread, and the bottom end of the vertical rod 10 is connected to the top of the rotating rod 1.

[0054] In this embodiment, in order to be able to rotate the rotating rod 1 to achieve the purpose of drilling the soil, a bearing 21 is further provided in the upper end of the square pipe 6, and a movable rod 9 is provided in the bearing 21. One end of the movable rod 9 extends into the square pipe 6 and is located below the outlet 20. The lower end surface of the movable rod 9 can be used to restrict the soil entering the square pipe 6 so that it can be discharged through the outlet 20.

[0055] Meanwhile, in this embodiment, in order to adjust the extension amount of the rotating rod 1 at the bottom of the circular tube 4, the vertical rod 10 is arranged to be connected to the connection hole on the movable rod 9 by means of threads. In this way, when it is necessary to adjust the position of the rotating rod 1 in the circular tube 4, the vertical rod 10 is rotated to change the position of the vertical rod 10 on the movable rod 9, thereby realizing the adjustment of the position of the rotating rod 1 in the circular tube 4.

[0056] A limiting nut 7 is further arranged on the movable rod 9. The limiting nut 7 is connected to the outer wall of the movable rod 9 by means of threads. The limiting nut 7 is used to fix the movable rod 9 in the square tube 6.

[0057] Since the arranged vertical rod 10 is connected to the movable rod 9 by means of threads, and the arranged movable rod 9 is connected to the square tube 6 through a bearing 21. Therefore, when the vertical rod 10 is rotated to change the position of the vertical rod 10 on the movable rod 9, in order to prevent the square tube 6 from driving the movable rod 9 and the vertical rod 10 to rotate synchronously under the action of friction, a limiting nut 7 is further arranged on the movable rod 9. When it is necessary to adjust the position of the vertical rod 10, the limiting nut 7 is rotated first so that the limiting nut 7 moves to the upper end of the square tube 6. The frictional resistance between the limiting nut 7 and the end face of the square tube 6 can be used to prevent the square tube 6 and the vertical rod 10 from rotating synchronously.

[0058] A first handle 8 is arranged on the side wall of the movable rod 9; a second handle 11 is further arranged on the side wall of the vertical rod 10.

[0059] In this embodiment, the arranged first handle 8 is used to facilitate the rotation of the movable rod 9, thereby driving the rotating rod 1 to rotate and drill holes in the soil; the arranged second handle 11 is used to rotate the vertical rod 10 and is used to adjust the extension length of the rotating rod 1 in the sleeve body.

[0060] A support plate 3 is further arranged on the circular tube 4. The support plate 3 is sleeved on the circular tube 4, and the bottom of the support plate 3 is flush with the bottom of the circular tube 4.

[0061] In this embodiment, in order to improve the stability between the circular tube 4 and the ground, a support plate 3 is further sleeved at the bottom of the circular tube 4.

[0062] The above specific embodiments have further elaborated on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above is only the specific embodiment of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
