[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-6 , an embodiment provided by the present invention:
[0024] A building sand and soil detector sampler: including a sampling cylinder 1, a grip 2 is fixedly connected to the outer surface of the sampling cylinder 1, an annular cutting knife 3 is fixedly connected to the bottom of the sampling cylinder 1, a connecting cylinder 4 is fixedly connected to the inner surface of the sampling cylinder 1, a rotating rod 5 is rotatably connected to the surface of the connecting cylinder 4, a knob 6 is fixedly connected to the top of the rotating rod 5, a pointer 7 is fixedly connected to the surface of the knob 6, a cutting plate 8 is fixedly connected to the bottom of the rotating rod 5, a fixed block 9 is fixedly connected to the inner surface of the sampling cylinder 1, a movable rod 10 is slidably connected to the surface of the fixed block 9, a movable block 11 is fixed to the bottom of the movable rod 10, a spring 12 is fixedly connected to the surface of the movable block 11, and a screw rod 13 is threadedly connected to the surface of the fixed block 9. During the sampling process, the sampler can seal the bottom of the sampler through the cutting plate 8, thereby preventing the sample from falling from the bottom of the sampling cylinder 1, ensuring the sampling quantity, eliminating the need for the tester to sample again, and improving the sampling efficiency.
[0025] Furthermore, the inside of the connecting cylinder 4 is hollow, and a plurality of circular holes are opened at the top of the connecting cylinder 4, and the circular holes are evenly distributed on the surface of the connecting cylinder 4. The other side of the connecting cylinder 4 inside the sampling cylinder 1 is the sampling chamber of the sampling cylinder 1. The top of the sampling chamber is the movable block 11, and the bottom is the cutting plate 8. The connecting cylinder 4 reserves space for the rotating rod 5 and the cutting plate 8 inside the sampling cylinder 1, and the angles of the cutting plate 8 and the pointer 7 are the same, enabling the tester to know the angle of the cutting plate 8 at the bottom of the sampling cylinder 1.
[0026] Furthermore, the cross-section of the top of the connecting cylinder 4 and the cross-section of the fixed block 9 form a circle on the inner surface of the grip 2, and the center of the circle is on the surface of the connecting cylinder 4. The cross-sectional area of the connecting cylinder 4 is larger than the cross-sectional area of the fixed block 9, and both the connecting cylinder 4 and the fixed block 9 are in a semi-circular shape.
[0027] Furthermore, a rectangular hole is formed at the bottom of the connecting cylinder 4. The cutting plate 8 slides out of the connecting cylinder 4 from the inside through the rectangular hole at the bottom of the connecting cylinder 4 via the rotating rod 5. The cutting plate 8 can cover the bottom of the sampling bin of the sampling cylinder 1 at the bottom of the sampling cylinder 1, thereby preventing the sample from leaking out from the bottom of the sampling cylinder 1. The small amount of sample brought into the connecting cylinder 4 by the cutting plate 8 from the rectangular hole can also be poured out from the circular hole at the top of the connecting cylinder 4.
[0028] Furthermore, the fixing block 9 and the movable block 11 have the same shape. The movable block 11 slides on the inner surface of the sampling cylinder 1 via the movable rod 10. At the same time, the movable block 11 also slides on the surface of the connecting cylinder 4. The height of the movable block 11 on the sampling cylinder 1 determines how much sample the sampling cylinder 1 can take.
[0029] Furthermore, the elastic force of the spring 12 acts on the movable block 11. The bottom of the screw rod 13 is in contact with and connected to the surface of the movable block 11. The screw rod 13 limits the height of the movable block 11 inside the sampling cylinder 1.
[0030] Furthermore, a threaded hole is formed on the surface of the fixing block 9. The screw rod 13 is threadedly connected to the threaded hole of the fixing block 9. By rotating the screw rod 13 on the fixing block 9, the height of the screw rod 13 on the sampling cylinder 1 can be changed, thereby changing the position of the movable block 11 inside the sampling cylinder 1.
[0031] Working principle: The sampling cylinder 1 is inserted into the sampling location through the annular cutter 3. The sample will enter the sampling bin inside the sampling cylinder 1. At this time, the rotating rod 5 is rotated through the knob 6. The rotating rod 5 drives the cutting plate 8 to rotate at the bottom of the connecting cylinder 4. The cutting plate 8 rotates 180 degrees at the bottom of the sampling cylinder 1. At this time, the cutting plate 8 covers the bottom of the sampling bin of the sampling cylinder 1, preventing the sample from falling from the bottom, ensuring the quantity of the sampled sample, eliminating the need for the tester to sample again, and improving the sampling efficiency.
[0032] By rotating the screw rod 13 on the threaded hole of the fixing block 9, the horizontal height of the screw rod 13 on the sampling cylinder 1 can be changed. The spring 12 makes the movable block 11 contact and connect to the bottom of the screw rod 13 through the elastic force. By adjusting the horizontal height of the movable block 11, the amount of sample taken by the sampling cylinder 1 can be adjusted. At the same time, by driving the movable block 11 to slide downward inside the sampling cylinder 1 via the movable rod 10, all the sample in the sampling bin of the sampling cylinder 1 can be discharged, making the operation more convenient.
[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
