Technical Field

[0001] The utility model belongs to the technical field of building foundation sample collection, and specifically relates to a building surveying and mapping foundation sample collection device. Background Technique

[0002] The foundation refers to the soil layer or rock that bears the loads of buildings, machinery and equipment, etc. Foundations are generally divided into two categories: natural foundations and artificial foundations. A natural foundation is a foundation that can meet the requirements of a building without artificial treatment, and an artificial foundation is a foundation that needs to be artificially reinforced to meet the requirements of a building. The soil layers used as building foundations are divided into rocks, gravel soils, sandy soils, silty soils, cohesive soils and artificial fill soils.

[0003] Before building a building, it is necessary for staff to take samples of the foundation soil layer to determine the bearing capacity of the soil layer. However, due to the large viscosity of some soils, the soil is easily adhered to the inner wall of the sampling equipment during sampling. If it is not cleaned in time, it will be mixed into the subsequent soil samples, thus affecting the subsequent detection accuracy. Content of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a building surveying and mapping foundation sample collection device, which solves the problem that some soils with large viscosity are easily adhered to the inner wall of the sampling equipment during sampling. If not cleaned in time, they will be mixed into the subsequent soil samples and affect the subsequent detection accuracy.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A building surveying and mapping foundation sample collection device includes a connecting rod. One end of the connecting rod is connected with a handle, and the end of the connecting rod far from the handle is connected with a mounting plate. A limiting ring is connected to the connecting rod, and a movable sleeve is rotatably connected to the connecting rod. Two pedal boards are connected to both sides of the movable sleeve. A sampling cover is installed on the mounting plate, a vertical chute is opened on the mounting plate, and a horizontal chute is opened on the mounting plate;

[0006] A groove is arranged inside the mounting plate, a connecting spring is connected inside the groove, one end of the connecting spring is connected with a fixed block, a slider is connected to the sampling cover, a cutting edge is connected to one end of the sampling cover, guiding grooves are opened on both sides of the sampling cover, guiding rods are connected inside the guiding grooves, a moving plate is slidably connected to the guiding rods, a scraping plate is connected below the moving plate, and ear plates are connected to both sides of the moving plate.

[0007] As a further scheme of the utility model: The handle is provided with an anti-slip rubber sleeve, the pedal board is provided with anti-slip lines, and there are two limiting rings respectively arranged above and below the movable sleeve.

[0008] As a further solution of the present utility model: the vertical chute and the horizontal chute are connected to each other and the whole is in an L shape, and the slider slides in the vertical chute and the horizontal chute.

[0009] As a further solution of the present utility model: the ear plate slides on the guide rod, a return spring is connected below the ear plate, and one end of the return spring is connected to the sampling cover.

[0010] As a further solution of the present utility model: there are four sliders in total, which are symmetrically centered on the axis of the sampling cover. A fixing groove is provided below the slider, and the scraping plate is in close contact with the inner wall of the sampling cover.

[0011] As a further solution of the present utility model: the end of the fixing block away from the connecting spring is designed to be hemispherical. The fixing block slides in the groove and is fitted with the fixing groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For this building surveying and mapping foundation sample collection device, by setting the pedal, cutting edge, guide rod, moving plate, ear plate, scraping plate and return spring, the staff steps on the pedal, so that the cutting edge below the sampling cover cuts the soil layer, thus ensuring the flatness of the sampled soil and avoiding the influence of plant roots on sampling. After that, the sampling cover is removed, and by pushing the ear plate to slide along the guide rod and compressing the return spring, the moving plate moves in the sampling cover. When the moving plate moves, the moving plate will push the soil in the sampling cover out, thus facilitating the staff to detect the soil. At the same time, the scraping plate will scrape off the soil adhered to the inner wall of the sampling cover, thus avoiding the influence of soil residue on the detection.

[0014] 2. For this building surveying and mapping foundation sample collection device, by setting the vertical chute, horizontal chute, slider, connecting spring, fixing block and fixing groove, after pushing the slider into the vertical chute, the sampling cover is rotated to make the slider move into the horizontal chute. When the sampling cover is rotated, the slider will push the fixing block to compress the connecting spring, so as to use the resilience of the connecting spring to push the fixing block into the fixing groove to fix the position of the slider and prevent the sampling cover from falling. And through the fixing method of the fixing block being fitted with the fixing groove, it is convenient for the staff to disassemble and assemble the sampling cover, thus facilitating the cleaning and maintenance of the sampling cover.

Specific embodiments

[0020] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: a building surveying and mapping foundation sample collection device, including a connecting rod 1, one end of the connecting rod 1 is connected with a handle 2, the end of the connecting rod 1 far from the handle 2 is connected with a mounting plate 3, a limiting ring 4 is connected to the connecting rod 1, a movable sleeve 5 is rotatably connected to the connecting rod 1, both sides of the movable sleeve 5 are connected with pedals 6, an anti-slip rubber sleeve is arranged on the handle 2, anti-slip patterns are arranged on the pedals 6, there are two limiting rings 4 in total, which are respectively arranged above and below the movable sleeve 5, the position of the movable sleeve 5 is restricted by the two limiting rings 4 to prevent the movable sleeve 5 and the pedal 6 from sliding together on the connecting rod 1 during use, and the anti-slip patterns on the pedal 6 can increase the friction force, thereby avoiding the pedal 6 from sliding when the worker steps on it.

[0022] A sampling cover 7 is installed on the mounting plate 3, a vertical chute 8 is opened on the mounting plate 3, a horizontal chute 9 is opened on the mounting plate 3, the vertical chute 8 and the horizontal chute 9 are connected to each other and the whole is in an L shape, the slider 13 slides in the vertical chute 8 and the horizontal chute 9, and through the sliding of the slider 13 in the vertical chute 8 and the horizontal chute 9, the staff can quickly position and install the sampling cover 7 on the mounting plate 3, saving the installation time.

[0023] A groove 10 is provided inside the mounting plate 3. A connecting spring 11 is connected inside the groove 10. One end of the connecting spring 11 is connected with a fixing block 12. A slider 13 is connected to the sampling cover 7. There are four sliders 13 which are symmetrically centered on the axis of the sampling cover 7. A fixing groove 21 is provided below the slider 13. The scraping plate 18 is in close contact with the inner wall of the sampling cover 7. One end of the fixing block 12 away from the connecting spring 11 is designed to be hemispherical. The fixing block 12 slides in the groove 10 and is fitted with the fixing groove 21. The connecting spring 11 rebounds to snap the fixing block 12 into the fixing groove 21, thereby fixing the sampling cover 7 and preventing the sampling cover 7 from moving and falling. The hemispherical design on one side of the fixing block 12 can be easily pushed by the slider 13, facilitating the staff to disassemble and assemble the sampling cover 7.

[0024] One end of the sampling cover 7 is connected with a cutting edge 14. Guide grooves 15 are provided on both sides of the sampling cover 7. Guide rods 16 are connected inside the guide grooves 15. A moving plate 17 is slidably connected to the guide rods 16. A scraping plate 18 is connected below the moving plate 17. Ear plates 19 are connected to both sides of the moving plate 17. The ear plates 19 slide on the guide rods 16. A return spring 20 is connected below the ear plates 19. One end of the return spring 20 is connected with the sampling cover 7. The movement of the moving plate 17 is guided by the guide rods 16 to prevent the moving plate 17 from tilting during movement. When the staff pushes the moving plate 17 to move, the scraping plate 18 will scrape the soil on the inner wall of the sampling cover 7, thus preventing soil residue from contaminating subsequent soil samples.

[0025] The working principle of the present utility model is as follows:

[0026] After aligning the slider 13 with the vertical chute 8, the sampling cover 7 is pushed, causing the slider 13 to slide along the vertical chute 8. Then, the sampling cover 7 is rotated so that the slider 13 slides into the horizontal chute 9. When the slider 13 slides in the horizontal chute 9, it will push the fixing block 12 into the groove 10, causing the fixing block 12 to compress the connecting spring 11. Thus, the connecting spring 11 rebounds to push the fixing block 12 into the fixing groove 21, fixing the position of the slider 13 and preventing the sampling cover 7 from falling. Then, the staff steps on the pedal 6 to make the cutting edge 14 cut the soil layer, ensuring the flatness of the sampled soil and preventing plant roots from affecting the sampling. After the sampling is completed, the sampling cover 7 is rotated in the reverse direction to remove the sampling cover 7. Then, the ear plate 19 is pushed to slide along the guide rod 16, causing the moving plate 17 to move inside the sampling cover 7. When the moving plate 17 moves, it will push out the soil sample inside the sampling cover 7. At the same time, the scraping plate 18 will scrape the soil adhering to the inner wall of the sampling cover 7, thus completely pushing out the soil sample for subsequent detection.
