Description

Technical field:

[0001] The utility model belongs to the field of desert construction, in particular to a sample unloading device for aeolian sand filling construction test. Background technology:

[0002] Desert areas have abundant reserves of aeolian sand, but lack natural building materials such as gravel and clay. When constructing water conservancy projects in desert areas, natural building materials often become a key issue restricting project construction. When constructing flood diversion channel projects, a large amount of filling materials are required. If aeolian sand is used as the main filling material, a large amount of soil materials can be transported out, thereby significantly reducing the project cost.

[0003] When using aeolian sand as the main filling material, in order to ensure the construction quality, it is necessary to sample the soil after construction and conduct various tests such as compaction. When sampling, a ring cutter is usually used to extract the sample soil. When removing the sample soil in the ring cutter (referred to as unloading), on-site test personnel usually use a small hammer to repeatedly knock on the outer wall of the ring cutter and the sample soil. This method is not only easy to cause deformation and damage to the ring cutter, but also has low efficiency in unloading. At the same time, the knocked sample soil is prone to random splashing, resulting in substandard test soil. Utility model content:

[0004] The utility model aims to provide a sample unloading device for aeolian sand filling construction test, overcomes the shortcomings of the above-mentioned prior art, and effectively solves the existing problem of low sample unloading efficiency.

[0005] The content of the utility model: A sample unloading device for a test of aeolian sand filling construction, comprising a receiving tray, a frame frame is installed in the receiving tray, a first screw hole is vertically opened on the cross beam of the frame frame, a first screw rod is screwed in the first screw hole, a pressing plate is installed at the bottom end of the first screw rod, second screw holes are horizontally opened on two vertical beams of the frame frame, a second screw rod is screwed in the second screw hole, and a clamp is rotatably connected to the inner end of the second screw rod.

[0006] Furthermore, hand wheels are installed at the top end of the first screw rod and the outer end of the second screw rod.

[0007] Furthermore, the pressing piece is circular in shape, and the clamping piece is arc-shaped.

[0008] Furthermore, a non-slip rubber pad is matched and installed in the arc groove of the clip.

[0009] Furthermore, square holes are horizontally opened on the two vertical beams of the frame, and the square holes are located directly below the second screw holes. A support rod is slidingly connected in a matching manner in the square holes, and a V-shaped support head is installed at the inner end of the support rod, and the V-shaped support head is used for temporarily placing the ring knife.

[0010] Furthermore, an anti-drop cap is installed on the outer end of the support rod.

[0011] Furthermore, a sample receiving tube is placed in the receiving tray, and the sample receiving tube is located directly below the ring knife.

[0012] Furthermore, a sampling notch is provided on a side wall of the receiving tray.

[0013] The beneficial effects of the utility model are as follows: different types of ring cutters can be clamped and fixed by two clamping pieces, and the sampled soil in the ring cutter can be pushed out by using a pressing piece, which can avoid the ring cutter from being damaged by knocking, improve the efficiency of sample unloading, and ensure that the test sample soil meets the test standards.

Specific implementation method:

[0018] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0019] like Figures 1 to 3 As shown, a sample unloading device for aeolian sand filling construction test comprises a receiving tray 1, a frame 2 is installed in the receiving tray 1, a first screw hole is vertically opened on the cross beam of the frame 2, a first screw rod 3 is screwed in the first screw hole, a pressing plate 4 is installed at the bottom end of the first screw rod 3, second screw holes are horizontally opened on both vertical beams of the frame 2, a second screw rod 5 is screwed in the second screw hole, a clamping plate 6 is rotatably connected to the inner end of the second screw rod 5, hand wheels 7 are installed at the top end of the first screw rod 3 and the outer end of the second screw rod 5, the pressing plate 4 is circular, the clamping plate 6 is arc-shaped, and an anti-slip rubber pad is matched and installed in the arc groove of the clamping plate 6.

[0020] Specifically, the ring cutter 10 can be clamped and fixed by two clamping pieces 6, and the sampled soil in the ring cutter 10 can be pushed out by using the pressing piece 4.

[0021] During actual use, the handwheel 7 is turned to rotate the second screw 5, so that the two clamps 6 clamp the ring cutter 10 and fix it. The clamped ring cutter 10 is coaxial with the pressing plate 4. At this time, the handwheel 7 installed on the top of the first screw 3 is rotated again to make the pressing plate 4 descend and press on the ring cutter 10 to push out the sampled soil; adjusting the rotation distance of the second screw 5 can enable the two pressing plates 4 to clamp and fix ring cutters 10 of different models and diameters.

[0022] like Figures 1 to 3 As shown, a sampling device for aeolian sand filling construction test is provided, wherein square holes are horizontally opened on the two vertical beams of the frame 2, and the square holes are located directly below the second screw holes. A supporting rod 8 is slidingly connected in a matching manner in the square holes, and a V-shaped supporting head 9 is installed at the inner end of the supporting rod 8, and the V-shaped supporting head 9 is used to temporarily place a ring knife 10. An anti-drop cap 11 is installed at the outer end of the supporting rod 8, and a sample receiving tube 12 is placed in the receiving tray 1, and the sample receiving tube 12 is located directly below the ring knife 10. A sampling notch 13 is opened on one side wall of the receiving tray 1.

[0023] Specifically, by placing the ring cutter 10 on the V-shaped support head, the two clamping pieces 6 can quickly clamp and fix the ring cutter 10.

[0024] During actual use, the support rod 8 in the square hole can be pushed so that the V-shaped support head is located directly below the pressing plate 4. At this time, the ring knife 10 can be placed on a temporary placement table composed of two V-shaped support heads, which further frees the hands of the experimenter and allows the experimenter to quickly operate the clamp 6 to clamp and fix the ring knife 10. When unloading the sample, the support rod 8 is pulled outward from the frame 2 to make the V-shaped support head away from the ring knife 10. At this time, the pressing plate 4 is operated to push the sampled soil out and drop it into the sample receiving tube 12 below; the sampling notch 13 can facilitate the sample receiving tube 12 to quickly enter and exit the receiving tray 1.
