Description

TECHNICAL FIELD

[0001] The utility model relates to building design soil exploration device technical field, specifically point to the sampling device for building engineering design. BACKGROUND

[0002] In building engineering design, soil exploration sampling is the key link of obtaining soil information and providing basic data for engineering construction. Through the analysis of different depth soil layer samples, the physical and mechanical properties, composition and the like of the soil can be accurately mastered, so that the building foundation design, construction process selection and the like can be reasonably planned.

[0003] The traditional soil sampling device usually inserts a simple sampling cylinder into the soil for sampling. After sampling is completed, the sample needs to be taken out of the sampling cylinder for subsequent analysis and preservation.

[0004] However, the traditional sampling device has obvious defects. When the sample is taken out of the sampling cylinder, it is difficult to ensure that the sample is completely taken out, and usually only the sampling cylinder can be knocked to make the sample fall in the receiving tray in a scattered state, which can seriously damage the layered structure of the soil sample. Moreover, in the subsequent preservation process, since the layered structure of the sample has been damaged, the sample is also easily damaged by external factors, which is difficult to meet the requirements of the building engineering design analysis demand for the layered integrity of the sample, and cannot provide accurate and reliable soil data support for building design.

A motor 6 is fixedly mounted inside the motor box 5. A sampling cylinder 7 is driven and connected to the drive shaft of the motor 6. The bottom of the sampling cylinder 7 is open and has serrations. A sampling window 8 is opened on the side wall of the sampling cylinder 7. A sealing cover plate 9 is fixed to the outside of the sampling window 8 by bolts. An inner push plate 10 is slidably connected to the inner wall of the sampling cylinder 7 by multiple rails 23. A sample storage box 11 is fixedly mounted on the rear side of the upper end of the mobile trolley 1. The sample storage box 11 has multiple arc-shaped placement slots 12 inside. A spring clamping assembly 13 is movably connected to one end of each arc-shaped placement slot 12.

[0028] The spring clamping assembly 13 includes a guide rod 14 movably inserted into one end of the arc-shaped placement groove 12. A clamping plate 15 is fixedly provided at one end of the guide rod 14 that extends into the arc-shaped placement groove 12, and a spring 24 is sleeved on the guide rod 14. The sample storage box 11 is hinged to the upper end with a box cover 16, and an arc-shaped groove 17 is provided inside the box cover 16 corresponding to each arc-shaped placement groove 12.

[0029] The inner frame 3 is rotatably connected to the outer frame 2 on both sides via pivots. A positioning disc 18 is fixedly mounted on one of the pivots, and the positioning disc 18 has several positioning holes 19. Positioning pins 20 are inserted into the outer frame 2, and these pins 20 are matched with the positioning holes 19, allowing for flexible adjustment of the sampling angle according to different sampling needs, thus improving the applicability and efficiency of sampling.

[0030] The working principle of this utility model is as follows: This device utilizes the mobility of the mobile trolley 1 to transport the equipment to the sampling location. The sampling angle (usually adjusted to a vertical position) can be adjusted via the rotatable connection between the outer frame 2 and the inner frame 3, in conjunction with the positioning disc 18 and positioning pin 20. The electric push rod 4 pushes the motor box 5 and the connected motor 6 and sampling cylinder 7 to move up and down. The motor 6 drives the sampling cylinder 7 to rotate, using the bottom serrations to cut into the soil for sampling. The inner push plate 10 can slide within the sampling cylinder 7 under the action of the track 23 to push out the sample. The sample storage box 11 is used to store the sample; the spring clamping assembly 13 and the arc-shaped groove 17 inside the box cover 16 together ensure the stability of the stored sample.

[0031] The working process of this utility model is as follows:

[0032] 1. Equipment positioning: Move the mobile trolley 1 to the designated sampling location.

[0033] 2. Angle adjustment: According to the actual sampling requirements, rotate the inner frame 3 and adjust the angle. Then, insert the positioning pin 20 on the outer frame 2 into the corresponding positioning hole 19 on the positioning disc 18 to fix the angle. It is usually in a vertical state, sampling vertically downwards from the ground.

[0034] 3. Sampling Operation: Start the electric push rod 4, whose piston end pushes the motor housing 5 downwards. Simultaneously, start the motor 6, which drives the sampling cylinder 7 to rotate. The serrated edge at the bottom of the sampling cylinder 7 cuts into the soil for sampling. Soil enters the sampling cylinder 7 through the bottom opening. Initially, the inner push plate 10 is located at the bottom of the sampling cylinder. As the sample enters, the inner push plate 10 is pushed to the top of the sampling cylinder. After sampling is completed, the electric push rod 4 drives the motor housing 5 and the sampling cylinder 7 to rise and reset.

[0035] 4. Sample collection: Remove the positioning pin 20, rotate the sampling tube 7 to a horizontal position, then insert the positioning pin 20 to fix it in place, rotate the sampling tube so that the sampling window 8 faces upward, then unscrew the sealing cover 9, operate from the sampling window 8, hold and slide the inner push plate 10 along the sampling window 8 to push the sample out smoothly from the bottom of the sampling tube to collect the sample.

[0036] 5. Sample storage: Open the lid 16 of the sample storage box 11 and place the sample in the arc-shaped placement slot 12 inside the sample storage box 11. When the sample is placed, the guide rod 14 of the spring clamping assembly 13 is compressed by the force and the spring 24 is compressed. After the sample is placed, the spring 24 pushes the clamping plate 15 to press and fix the sample. Close the lid 16. The arc-shaped grooves 17 inside the lid 16 corresponding to each arc-shaped placement slot 12 further fix the sample, completing the sample storage work.
