AI Technical Summary
In the prior art, the sand filling cylinder is not aligned with the openings of the substrate, which leads to the inability to fill the holes during the standard sand falling, creating a cavity, affecting the calculation of compaction degree; at the same time, the excess vertebral sand after the sand filling cylinder is pulled out is difficult to effectively collect, resulting in loss.
A roadbed soil compaction test device is designed. By placing the outer arc surface of the sand filling cylinder against the inner arc against the cylinder arc, the traction plate and the relay plate are used to align the circular holes of the sand filling cylinder with the circular holes of the cylinder plate. When the sand filling cylinder is pulled open, the sand plate pushes the standard sand body sand into the sand bearing frame, pulls the pulling frame block to pull out the sand bearing frame, and realizes automatic recovery of standard sand.
The automatic alignment of the sand filling cylinder and the roadbed holes is achieved, ensuring the smooth fall of standard sand, reducing the generation of cavity, and improving the accuracy of compaction. At the same time, by automatically collecting excess standard sand, the loss of standard sand is reduced.

Specific implementation manner
[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.
[0027] In the present application, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0028] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement.

[0029] When in use, this subgrade soil compaction test device can automatically align the opening of the sand - filling cylinder with the opening on the base plate to ensure that the standard sand in the sand - filling cylinder can smoothly slide into the dug hole. And when the sand - filling cylinder is pulled out, it can automatically scrape the cone flat and automatically collect the excess standard sand to reduce the loss of standard sand.
[0030] In the related art, since the opening of the sand pouring cylinder and the substrate are not aligned, it may cause the standard sand to fail to fill the dug hole during the falling process, resulting in a cavity in the dug hole, which in turn affects the calculation of the compaction degree. Moreover, after the sand pouring cylinder is pulled out, the excess conical sand is too fine and it is inevitable to cause a large amount of loss when collecting it with a shovel spoon under the influence of the construction site environment.
[0031] To solve the problems in the related art to a certain extent, the embodiment of the present application provides a subgrade soil compaction test device. When in use, only need to place the outer arc surface of the sand pouring cylinder against the inner arc of the cylinder-against arc 13. After the sand pouring cylinder is placed, the spring of the traction plate 16 pushes the relay plate 14 in the reverse direction, so that the relay plate 14 drives the outer push column 12 to slide in the direction of the elevation column 11, so that the outer push column 12 drives the cylinder-against arc 13 to push the sand pouring cylinder, making the circular hole of the sand pouring cylinder align with the circular hole of the cylinder-placement plate 1 to ensure that the sand pouring cylinder and the subgrade dug hole are automatically aligned. When the sand pouring cylinder is lifted, the standard sand on its upper cone spreads out above the cylinder-placement plate 1. By pushing the sand-pushing plate 4 to slide in the direction of the anti-dust frame 5, the sand-pushing plate 4 pushes the conical standard sand above the cylinder-placement plate 1 into the sand-receiving frame 6. Then, pull the pulling frame block 7 so that the pulling frame block 7 drives the sand-receiving frame 6 to be pulled out from the anti-dust frame 5, so as to recycle the standard sand in the sand-receiving frame 6 to reduce the loss of the standard sand.
