Description

Technical Field

[0001] The utility model relates to the technical field of earthwork compaction degree sampling, and more specifically, it relates to an earthwork compaction degree sampling device. Background Technique

[0002] In the existing technology, the earthwork compaction degree sampling device is a commonly used equipment in civil engineering for evaluating the compaction degree of soil. However, the existing earthwork compaction degree sampling device has certain limitations in use, especially during the sampling process. Specifically, the existing equipment usually uses the core cutter method for sampling, and this method requires inserting the sampling shell into the soil to obtain soil samples. However, there are some problems when the existing equipment inserts the sampling shell into the soil, and these problems affect the convenience and efficiency of the equipment.

[0003] First of all, the existing earthwork compaction degree sampling device often requires a large amount of force when inserting the sampling shell. Due to the different compaction degrees of the soil, greater resistance may be encountered during the insertion process. The existing equipment often lacks an effective assisting mechanism, so that the operator needs to spend a large amount of effort to insert the sampling shell into the soil. This not only increases the labor intensity of the operator, but also may lead to inaccurate sampling or deviation during the sampling process.

[0004] Secondly, the existing earthwork compaction degree sampling device lacks precise control when inserting the sampling shell. Due to the different compaction degrees of the soil, the sampling shell may shift or tilt during the insertion process, resulting in inaccurate sampling. The existing equipment often lacks precise guiding and adjusting mechanisms, making it difficult for the operator to control the insertion depth and angle of the sampling shell, thus affecting the accuracy and reliability of sampling. Content of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the utility model provides an earthwork compaction degree sampling device to solve the technical problems mentioned in the background technique.

[0007] (II) Technical Solutions

[0010] The present utility model is further configured such that there are multiple friction blocks, and multiple friction grooves are respectively opened on each friction block.

[0030] Please refer to Figures 1-5, An earthwork compaction degree sampling device, including a sampling shell 1, an insertion mechanism is arranged on the sampling shell 1. The insertion mechanism includes an intermediate rod 2, a follower plate 3, a fixed sleeve 4, a mounting sleeve 5, an adjusting rod 6, an adjusting plate 7, a fixed strip 8, a one-way mechanism and a fixing mechanism. The intermediate rod 2 is installed on the sampling shell 1. There are two follower plates 3, and mounting sleeves 5 are respectively installed on the two follower plates 3. A fixed sleeve 4 is installed in the mounting sleeve 5. The one-way mechanism is connected in cooperation with the fixed sleeve 4 and the intermediate rod 2. The adjusting rod 6 is rotationally clamped on the follower plate 3. The adjusting plate 7 is installed on the adjusting rod 6. The fixed strip 8 is installed on the adjusting plate 7. The fixing mechanism is installed on the intermediate rod 2. The one-way mechanism includes a sliding plate 9 and a friction block 10. An inclined groove 11 is opened on the inner wall of the fixed sleeve 4. The sliding plate 9 is slidably connected in the inclined groove 11. The friction block 10 is installed on the sliding plate 9. There are multiple friction blocks 10. Multiple friction grooves 12 are respectively opened on each friction block 10. The friction grooves 12 abut against the side wall of the intermediate rod 2. Springs 13 are respectively arranged on the multiple friction blocks 10. The multiple springs 13 are respectively connected to the fixed sleeve 4. Push plates 14 are respectively arranged on the multiple sliding plates 9. A lateral groove 15 is opened on the side wall of the fixed sleeve 4. The push plate 14 is slidably connected in the lateral groove 15. A threaded sleeve 16 is provided on the fixed sleeve 4 in a threaded manner. A follower frame 17 is rotatably provided on the threaded sleeve 16. A push sleeve 18 is provided on the follower frame 17. The push sleeve 18 is slidably connected to the fixed sleeve 4 and abuts against the multiple push plates 14. The fixing mechanism includes a synchronous plate 19, a fixing rod 20 and a pressing plate 21. The synchronous plate 19 is rotatably connected to the intermediate rod 2 and the fixing rod 20. The fixing rod 20 is installed with the pressing plate 21.

[0031] In this embodiment, when soil sampling is required, first, the pressing plate 21 is pressed on the corresponding position, then one foot is pressed on the pressing plate 21, and then the other foot is put on the fixed strip 8, and the hand holds the intermediate rod 2. Since both the synchronous plate 19 and the follower plate 3 are rotationally connected, one foot fixes and the other foot can adjust the position of the sampling shell 1. Then the sampling shell 1 is moved to the corresponding position. Then, when the foot on the adjusting plate 7 moves upward, it will drive the mounting sleeve 5 and the fixed sleeve 4 to move upward accordingly. Then, due to the upward movement, the friction block 10 is in an expanded state, so it can move upward. Then, after moving to the corresponding position and pushing downward, due to the action of the spring 13, it will drive the sliding plate 9 to press and contract the inclined groove 11. At this time, the one-way plate and the fixed sleeve 4 are in a one-way self-locking state. Therefore, when the foot kicks downward, it will provide force. Then, at this time, the hand holds the intermediate rod 2 vertically. Thus, one insertion can be completed. When the insertion force is too large, it can be lifted a little each time for multiple insertions, thereby completing the sampling process.

[0032] More specifically, when continuous unlocking is required, the rotation of the threaded sleeve 16 can drive the follower sleeve to move downward, and then the push sleeve 18 is used to push the push plate 14, causing the slide plate 9 to expand and the spring 13 to compress. At this time, the friction block 10 cannot fit on the middle rod 2, thus completing the unlocking process.

[0033] In summary, when the overall device is in use or operation: when soil sampling is required, first, the pressing plate 21 is pressed at the corresponding position, then one foot is pressed on the pressing plate 21, and then the other foot is put on the fixing strip 8, and the middle rod 2 is held by hand. Since both the synchronous plate 19 and the follower plate 3 are rotatably connected, one foot is fixed and the other foot can adjust the position of the sampling shell 1. Then, the sampling shell 1 is moved to the corresponding position. Then, when the foot on the adjusting plate 7 moves upward, it will drive the mounting sleeve 5 and the fixing sleeve 4 to move upward accordingly. Then, due to the upward movement, the friction block 10 is in an expanded state, so it can move upward. Then, after moving to the corresponding position and pushing downward, the spring 13 will drive the slide plate 9 to press against the inclined groove 11 and contract. At this time, the one-way plate and the fixing sleeve 4 are in a one-way self-locking state. Therefore, when the foot kicks downward, it will provide force. Then, at this time, the hand holds the middle rod 2 vertically, so one insertion can be completed. When the insertion force is too large, it can be lifted a little each time for multiple insertions, thus completing the sampling process. When continuous unlocking is required, the rotation of the threaded sleeve 16 can drive the follower sleeve to move downward, and then the push sleeve 18 is used to push the push plate 14, causing the slide plate 9 to expand and the spring 13 to compress. At this time, the friction block 10 cannot fit on the middle rod 2, thus completing the unlocking process.

[0034] Among all the solutions mentioned above, for the connection between two components, welding, bolt and nut connection, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
