Description

Technical Field

[0001] This utility model relates to the technical field of soil hardness testing, and in particular to a roadbed soil hardness testing device. Background Technology

[0002] As a crucial transportation infrastructure, the quality of the railway subgrade directly affects the safety and comfort of the railway. Ensuring that the hardness of the subgrade soil meets standards is paramount during railway construction. Traditional soil testing methods typically rely on manual sampling, bringing the samples back to the laboratory for analysis. This method is not only inefficient, but environmental factors during sample transportation can also alter the properties of the soil samples, affecting the accuracy of the test results. Soil hardness is closely related to moisture content; drying the soil samples allows for more accurate measurement of parameters such as dry density. Therefore, how to quickly and accurately collect, transport, and dry samples on-site has become a current technological bottleneck. While existing soil testing devices offer some on-site testing methods, most lack integrated design and cannot efficiently and accurately complete soil sample collection, transfer, and drying, resulting in an unsmooth testing process and high error rates. To address these issues, this application provides a roadbed soil hardness testing device. Utility Model Content

[0007] Preferably, the multidimensional adjustment robotic arm moves horizontally at the top of the translation slide rail via a cylinder.

[0008] Preferably, a number of one-way rotating plates are installed at equal intervals on the opposite surfaces of the two drying boxes, and storage racks for use with soil storage drawers are installed inside the drying boxes at positions corresponding to the one-way rotating plates.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] While existing soil testing equipment offers some on-site testing methods, most lack integrated design, making it difficult to efficiently and accurately complete soil sample collection, transfer, and drying. This results in a less-than-smooth testing process and a higher error rate. Please refer to... Figures 1-5 This embodiment provides a roadbed soil hardness testing device, solving the technical problem of complex and lengthy procedures in soil hardness testing. The device includes a support base plate 1 serving as a foundation. Drying chambers 2 for drying soil are installed on both sides of the top of the support base plate 1. A translational slide rail 3 is installed in the middle of the top of the support base plate 1. A multi-dimensional adjustable robotic arm 4 is slidably mounted on the top of the translational slide rail 3, capable of grasping and placing freshly collected soil. A soil sampling support chamber 5 is installed on one side of the translational slide rail 3. Several vertically moving stabilizing rods 6 are fixedly connected at equal intervals around the top of the soil sampling support chamber 5. The tops of the vertically moving stabilizing rods 6 are... A soil-collecting cylinder 9 is installed on the connecting support frame 10. A soil-collecting cover 11 is fixedly connected to the extension end of the soil-collecting cylinder 9. The soil-collecting cylinder 9 drives the soil-collecting cover 11 to be inserted into the ground, thereby realizing the function of soil collection. The vertically moving stabilizer 6 can increase the height of the soil-collecting cylinder 9, so that the soil-collecting cover 11 has enough lifting space. A discharge window 8 is opened on one side of the soil-collecting support chamber 5. A discharge support frame 7 is installed at the discharge end of the discharge window 8. A horizontal moving cylinder 12 is installed at the top of the discharge support frame 7. A connecting discharge frame 13 is installed at the extension end of the horizontal moving cylinder 12 through the base. A soil collection storage drawer 14 is installed on one side of the top of the connecting discharge frame 13.

[0017] The connecting discharge rack 13 extends into the soil extraction support chamber 5 through the discharge window 8 to facilitate the collection of soil extracted by the soil extraction cover 11.

[0018] During operation, the activated soil sampling cylinder 9, supported by the vertical moving stabilizer 6, presses down the soil sampling cover 11 to extend into the ground, thereby collecting soil. Subsequently, the activated horizontal moving cylinder 12 pushes the connecting discharge frame 13 into the soil sampling support chamber 5 until the soil sampling storage tray 14 at the top of the connecting discharge frame 13 is directly below the soil sampling cover 11. At this time, the soil sampling cover 11 is moved back and forth vertically several times to shake out the soil inside, so that it can be collected by the soil sampling storage tray 14. Then, the horizontal moving cylinder 12 is reset, and the multi-dimensional adjustment robotic arm 4 will pick up the soil sampling storage tray 14 and put it into the drying chamber 2 to quickly dry the soil, facilitating subsequent testing. This cycle is repeated to quickly test the soil in the designated area.

[0019] In order to expand the range of operation of the multi-dimensional adjustment robotic arm 4, the multi-dimensional adjustment robotic arm 4 moves horizontally at the top of the translation slide rail 3 via a cylinder.

[0020] Several one-way rotating plates 16 are installed at equal intervals on opposite sides of the two drying boxes 2. Inside the drying box 2, at the corresponding positions of the one-way rotating plates 16, there are storage racks 15 that are used in conjunction with the soil storage drawer 14.

[0021] Both drying chambers 2 have several horizontal slots running through their sides, allowing them to connect to the air outlet of an external dryer.

[0022] During the soil storage stage, the multi-dimensional adjustment robotic arm 4 places the soil storage tray 14 on the storage rack 15 inside the drying box 2, while the one-way flip plate 16 can prevent the soil storage tray 14 inside the drying box 2 from sliding out and can increase the sealing of the drying box 2, so that when the dryer is connected later, the hot air can stay inside the drying box 2 for a longer time.
