Description

Technical Field

[0001] The present invention relates to the technical field of foundation soil detection devices, and specifically to an indoor foundation soil detection device. Background Technique

[0002] The foundation refers to the soil or rock mass that supports the foundation under a building. The soil layers serving as building foundations are divided into rock, gravel soil, sandy soil, silt, cohesive soil, and artificial fill. Foundations are of two types: natural foundations and artificial foundations (composite foundations). A natural foundation is a natural soil layer that does not require human reinforcement. For example, the Chinese patent with the publication number CN216900531U discloses a foundation soil erosion detection device, which includes a soil loosening component installed on the machine body for loosening the soil in the machine body, a crushing component rotatably connected in the machine body, and a detection component communicated in the machine body. By adding foundation soil into the machine body and turning on the soil loosening component, the soil loosening component can loosen the foundation soil, and when the soil loosening component rotates, it can drive the crushing component to rotate in the machine body through a connecting component.

[0003] However, the above solution has the following deficiencies: In the above patent, the foundation soil is loosened by the soil loosening component, and the crushing component is driven to rotate in the machine body through the connecting component. Thus, under the action of the soil loosening component and the crushing component, the foundation soil in the machine body can be effectively loosened, and the detection component detects the foundation soil. However, in the actual operation process, since the device is reused and the soil properties in each environment to be detected are also different, when the soil in another environment remains in the device, it may be mixed with the new soil during the stirring process, resulting in inaccurate data during the testing process. Therefore, we introduce an indoor foundation soil detection device. Summary of the Invention

And under the limitation of the extrusion rod 20, the push rod 19 moving to the lower side will be continuously extruded. Through the extrusion of the push rod 19, the foundation soil remaining within the groove 17 is pushed out.

After the storage is completed, the baffle 3 is inserted into the collection box 2. The adjustable transmission mechanism includes an internal and external toothed ring 30. As Figure 9 shown, a number of teeth are provided on the inner side of the internal and external toothed ring 30, and a tooth groove is provided on the outer side. Through the setting of this tooth groove, the internal and external toothed ring 30 can drive the transmission gear 35 to move when moving. The internal and external toothed ring 30 is arranged within the connecting cavity 36. A number of teeth are provided on both the inner side and the outer side of the internal and external toothed ring 30. The outer side of the internal and external toothed ring 30 meshes with the transmission gear 35. The transmission gear 35 is slidably connected to the outer side of the square rod 38. The upper end of the square rod 38 is movably connected within the connecting cavity 36, and the lower end is fixedly connected to the output end of a transmission motor 28. The transmission motor 28 is fixedly connected within the detection box 1. A number of electric telescopic rods 37 are fixedly connected within the lower end of the connecting cavity 36. The upper ends of the electric telescopic rods 37 are movably connected to the lower end of the internal and external toothed ring 30.

[0020] The sample pressing and detecting mechanism includes an experimental cavity 9 which is opened in the detecting box 1. A pressing plate 7 is slidably connected in the experimental cavity 9. The pressing plate 7 is fixedly connected to the output end of a telescopic cylinder 6. The telescopic cylinder 6 is fixedly installed in the detecting box 1. A plug plate 11 is movably installed at one end of the experimental cavity 9. An observation window 29 is fixedly installed on one side of the detecting box 1, and there are scales on the outside of the observation window 29.

[0021] Working principle: During use, the foundation soil in the area to be detected can be stored through the collection box 2. After the storage is completed, the baffle 3 is inserted into the collection box 2, and the collection box 2 storing the foundation soil is carried into the laboratory. When the foundation soil needs to be detected, the collection box 2 is installed on the upper end of the detecting box 1 through a buckle. During the installation process, the lower end of the collection box 2 will squeeze the connecting rod 4, and at this time, the lifting plate 5 will move downward. When the installation is completed, the lifting plate 5 moves to the inner bottom of the detecting box 1. Turn on two electric telescopic rods 37 to drive the internal and external toothed rings 30 to move downward so that they are engaged with the connecting gear 24. During the movement of the internal and external toothed rings 30, the transmission gear 35 will move along. Turn on the transmission motor 28 to drive the square rod 38 to start rotating. The rotation of the square rod 38 drives the transmission gear 35 to start rotating. Since the transmission gear 35 is engaged with the internal and external toothed rings 30, the internal and external toothed rings 30 will rotate following the transmission gear 35. At this time, the connecting gear 24 will start to rotate clockwise. Through the clockwise rotation of the connecting gear 24, a number of connecting blocks 16 extend into the external environment. When all the extensions are completed, the transmission motor 28 is turned off. Control the electric telescopic rod 37 to move upward to drive the internal and external toothed rings 30 to be engaged with the toothed ring 23. Through the transmission of the transmission motor 28, the connecting column 15 rotates clockwise. Under the block of the limiting plate 21, the a number of connecting blocks 16 moving in the clockwise direction will not bend. Pull out the baffle 3. At this time, the foundation soil in the collection box 2 will enter the detecting box 1, and the foundation soil is crushed by a number of connecting blocks 16 rotating clockwise. Turn on the connecting motor 27 to drive the pulley 26 connected to it to rotate. Under the connection of the belt 25, a number of pulleys 26 rotate synchronously. At this time, the connecting roller 8 will start to rotate. The crushed foundation soil will enter the groove 17. At this time, under the rotation of the connecting roller 8, the foundation soil in the groove 17 will enter the experimental cavity 9 through the feeding through groove 10. And under the limit of the extrusion rod 20, the push rod 19 moving to the lower side will be continuously extruded. Through the extrusion of the push rod 19, the foundation soil remaining in the groove 17 is pushed out. When the push rod 19 is no longer in contact with the extrusion rod 20, the push rod 19 returns to its original position under the elastic force of the return spring 18. After the foundation soil fills the test chamber 9, close the connection motor 27 to stop the connecting roller 8 from rotating, and open the telescopic cylinder 6 to drive the pressing plate 7 to move. Squeeze the foundation soil in the test chamber 9 through the moving pressing plate 7. The compression distance of the foundation soil sample can be observed through the observation window 29 and the scale on its surface. By setting multiple groups of experiments, the erosion degree of different foundation soils can be detected; After the detection is completed, the foundation soil after the experiment can be taken out by opening the plug plate 11. According to the above method, make the winding column 14 rotate counterclockwise to wind several connecting blocks 16 into the storage cavity 13, and remove the collection box 2. At this time, under the elastic force of the support spring 12, the lifting plate 5 moves upward to clean the connecting column 15 and the inside of the detection box 1. At the same time, when the T-shaped blocking plate 32 no longer contacts the connecting roller 8, under the elastic force of the connecting spring 34, the two T-shaped blocking plates 32 block the connecting through groove 33 to prevent the soil hanging down from falling into the bottom of the detection box 1 through the connecting through groove 33. When the lifting plate 5 moves to the upper protrusion of the connecting column 15, the lifting plate 5 stops moving at this time, and the operator can clean the surface of the lifting plate 5.
