[0002] Compactors are mainly used in construction projects such as highways and railways, as well as in laboratory geotechnical tests. Before using a compactor, the maximum dry density and optimum moisture content of the soil need to be determined to obtain the degree of compaction. The degree of compaction can be used to evaluate the compaction performance of the soil. Chinese utility model patent CN220251498U discloses a compactor, relating to the field of compaction testing technology. This compactor includes a base plate, with support plates fixedly connected to both sides of the upper part of the base plate.

A compaction cylinder is fixedly connected to the middle of the upper part of the base plate, with the upper end of the compaction cylinder perpendicularly corresponding to the lower end of the compaction hammer. During compaction operations, because the cylinder is open, the soil inside is easily impacted, causing dust to be stirred up, leading to environmental pollution and potentially affecting the health of workers.

[0025] In the description of this utility model, it should be noted that the terms and nouns in the various embodiments, such as "upper", "lower", "front", "back", "left", and "right", which indicate the location, are only used to simplify the description of the positional relationship based on the accompanying drawings. They do not mean that the components and devices referred to must be operated in accordance with the specific location and limited operation and method or structure in the specification. Such directional terms do not constitute a limitation on this utility model.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Specific Implementation Plan 1: Combining Figures 1 to 5 As shown, this utility model provides an electric compaction device, including a column 1. An electric compaction device 2 is provided on the upper side of the column 1. A soil sample holding component is provided below the electric compaction device 2. The soil sample holding component includes two parallel and oppositely arranged side plates 4. An upper baffle 5, a lower plate 9, and a bottom plate 10 are provided between the two side plates 4, which are parallel to each other and perpendicular to the side plates 4. The upper baffle 5 and the lower plate 9 are detachably mounted on the side plates 4. The upper baffle 5 has a compaction pestle through-hole 501, through which the compaction pestle 3 of the electric compaction device 2 passes to compact the soil sample 15 in the measuring cylinder 6. The lower plate 9 has an annular groove 12 at its upper end. A ring gear 7 is engaged in the annular groove 12 by an annular slider 701 at its bottom without affecting the rotation of the ring gear 7. The ring gear 7 is a gear with teeth on both its inner and outer rings. The inner ring teeth of the ring gear 7 mesh with the measuring cylinder gear 8, which is rotatably mounted on the lower plate 9. The measuring cylinder gear 8 is detachably mounted on the lower plate 9. A measuring cylinder 6 is provided above the measuring cylinder gear 8. The distance between the upper opening of the measuring cylinder 6 and the upper baffle 5 is 0.1cm-1cm, preferably 0.2cm-0.5cm. A drive motor 14 is provided on the bottom plate 10. The output end of the drive motor 14 is connected to the transmission shaft. The transmission shaft passes through the lower plate 9 and is connected to the transmission gear 11. The transmission gear 11 meshes with the outer ring teeth of the ring gear 7. This is used to drive the transmission shaft to rotate via the drive motor 14, thereby driving the transmission gear 11 to rotate, which in turn drives the ring gear 7 to rotate, and finally drives the measuring cylinder gear 8 and the measuring cylinder 6 to rotate.
[0028] The inner diameter of the measuring cylinder 6 is the same as the diameter of the compaction pestle 3, or the inner diameter of the measuring cylinder 6 is larger than the diameter of the compaction pestle 3. The inner wall of the measuring cylinder 6 is in contact with the outer wall of the compaction pestle 3, so that when the measuring cylinder 6 rotates, the compaction pestle 3 can perform circumferential compaction on the soil sample 15 inside the measuring cylinder 6.
[0029] The measuring cylinder 6 is a transparent measuring cylinder, which makes it easy to observe the compaction of the soil sample 15 inside the measuring cylinder 6.
[0030] It should be noted that there is a gap between the measuring cylinder 6 and the upper baffle 5. Due to the small gap, it can prevent a large amount of dust from flying off during the compaction process of the soil sample 15, but it does not completely block it. It is sufficient to prevent a large amount of dust from flying off during the experiment. The electric compaction device 2 is an existing device.
[0031] The measuring cylinder gear 8 is detachably connected to the lower plate 9 via a measuring cylinder shaft 13. The top of the measuring cylinder shaft 13 has a slotted or cross-shaped groove. At the center of the bottom of the measuring cylinder gear 8, a shaft mounting port 801 is provided, matching the position of the measuring cylinder shaft 13. The shaft mounting port 801 contains a mounting port limiting block 802 that matches the slotted or cross-shaped groove. The measuring cylinder gear 8 can be engaged with the measuring cylinder shaft 13 via the mounting port limiting block 802. The measuring cylinder shaft 13 is rotatably connected to the lower plate 9. This design facilitates the addition or removal of the soil sample 15 after the measuring cylinder 6 is removed, as the distance between the measuring cylinder 6 and the upper baffle 5 is too small, and is intended to prevent difficulties in adding or removing the soil sample 15.
[0032] Both sides of the upper baffle 5 and the lower plate 9 are equipped with sliders, and the side plates 4 on both sides are provided with grooves corresponding to the sliders, so that the upper baffle 5 and the lower plate 9 can be detachably installed on the grooves of the side plates 4 via the sliders. The upper baffle 5 is designed to prevent the soil sample 15 from flying during the compaction process, and its detachable design allows for the addition of soil sample 15 without removing the measuring cylinder 6; the detachable design of the lower plate 9 allows for the addition of soil sample 15 into the measuring cylinder 6 or the removal of the compacted soil sample 15, or for easy replacement when parts are damaged. It should be noted that the drive motor 14 is only placed on the base plate 10, and is not fixed to the base plate 10.
[0033] When the measuring cylinder 6 rotates, the positions of two adjacent compaction pestles 3 falling overlap by 1 / 2 to 3 / 4, which can be achieved by setting the motor parameters. The rotation speed of the measuring cylinder 6 should not be too high to avoid excessive centrifugal force caused by excessive rotation of the soil sample 15 inside the measuring cylinder 6, resulting in uneven compaction.
[0034] The shape of the perforation 501 of the compactor is matched with that of the compactor 3.
[0035] Working principle:
[0036] Remove the upper baffle 5, add the test soil sample 15 into the measuring cylinder 6, then reinstall the upper baffle 5, turn on the drive motor 14, and observe that the measuring cylinder 6 rotates normally and the soil sample 15 in the measuring cylinder 6 does not undergo centrifugal force. Then turn on the electric compaction device 2, and the compaction pestle 3 continuously compacts the soil sample 15 in the measuring cylinder 6. After working for a period of time, stop the drive motor 14 and the electric compaction device 2, and observe whether there are any uncompacted parts in the soil sample 15. If so, the measuring cylinder 6 can be rotated by the drive motor 14 at a certain angle and compaction can be started again to avoid uncompacted parts. When it is observed that the compaction is completed, stop the drive motor 14 and the electric compaction device 2 again, remove the lower plate 9, remove the measuring cylinder 6, and take out the compacted soil sample 15.
[0037] Although the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
