Description

Technical Field

[0001] The utility model relates to the technical field of soil bulk density detection, in particular to a soil bulk density measuring device. Background Art

[0002] Soil bulk density, also known as dry bulk density, refers to the mass of dried soil per unit volume (including soil particles and pores between soil particles). This indicator can reflect the tightness of the soil and help calculate the weight of the soil and the number of each component. In engineering geology, soil bulk density is an important physical property indicator used to calculate foundation settlement, soil pressure and slope stability. In addition, soil bulk density is also a key indicator for evaluating soil fertility and physical and chemical properties. Different crops have different requirements for soil bulk density. When conducting soil bulk density testing, a sampling head is required to remove the soil test block from the ground while squeezing the soil. The current mainstream sampling method is manual sampling with a hammer and a shovel, which is inefficient and wastes manpower.

[0003] After searching, the Chinese patent publication number CN117419956A discloses a sampling device for measuring soil bulk density, a pneumatic impact device, a sampling head, a plurality of telescopic cavities, a packaging cavity, a plurality of telescopic plates and a digging module; the sampling head is fixedly arranged at the bottom end of the pneumatic impact device; the packaging cavity is arranged inside the sampling head, and the packaging cavity is exposed to the bottom surface of the sampling head for receiving soil samples; a plurality of telescopic cavities are arranged inside the sampling head, and a plurality of telescopic cavities are exposed to the bottom surface of the sampling head.

[0004] In view of the problem that the above technology lacks the function of using a scraper to slowly remove the soil outside the sampling head after the sampling head is taken out of the soil, and that manual scraping of the soil may press the soil and cause deviations in the soil bulk density measurement; therefore, a soil bulk density measuring device is proposed.

[0030] An extension rod 6 is fixedly connected to one end of the main box 1, a sleeve 7 is fixedly connected to one end of the extension rod 6, a sampling head 8 is fixedly connected to one end of the sleeve 7, and an inclined platform 10 is fixedly connected to the sampling head 8 and one end of the sleeve 7;

[0031] When sampling, the extension rod 6 can insert the sampling head 8 into the soil through the sleeve 7. When the sampling head 8 is completely in the soil, the sampling head 8 is taken out of the soil. A boss is provided on one side of the sleeve 7 to prevent the soil inside the sampling head 8 from being squeezed. At the same time, the inclined platform 10 can reduce the resistance of the sampling head 8 and the sleeve 7 when entering the soil, thereby reducing the influence on the sample bulk density.

[0032] After the sampling head 8 is taken out, the sampling head 8 is inverted on the rotating disk 17, and then the scraper 1 21 is rotated to fit the outer wall of the sampling head 8. When the rotating motor 16 rotates, the soil outside the sampling head 8 is scraped off, and then the scraper 2 23 on the lifting bracket 22 can be rotated to gradually flatten the excess soil at one end of the sampling head 8, and the excess soil is taken out to control the sample weight while preventing changes in the sample bulk density.

[0033] In this embodiment, the main box 1 is fixedly connected to a support frame 12, one end of the support frame 12 is fixedly connected to a drive motor 11, a drive gear 13 is fixedly connected to the power output end of the drive motor 11, one end of the support frame 12 is rotatably connected to a drive gear 2 14, one end of the drive gear 2 14 is meshed with the drive gear 1 13, and both ends of the drive gear 2 14 are fixedly connected to eccentric wheels 15. When the drive motor 11 is working, the drive gear 1 13 and the drive gear 2 14 will rotate to drive the two sections of the eccentric wheels 15 to rotate, so that the main box 1 can vibrate and drive the sampling head 8 to embed into the soil.

[0034] In this embodiment, a support rod 2 is fixedly connected to one side of the main box 1, a telescopic tube 3 is slidably connected to one end of the support rod 2, a support plate 4 is fixedly connected to one end of the telescopic tube 3, a spring 5 is fixedly connected to the support plate 4 and one end of the support rod 2, and the support rod 2 cooperates with the spring 5 to place the device on the ground more stably, and at the same time, it is convenient to insert the sampling head 8 into the ground at a vertical angle, so as to prevent the sampling head 8 from deflecting during sampling, thereby squeezing the soil and affecting the soil bulk density.

[0035] In this embodiment: when sampling, the extension rod 6 can insert the sampling head 8 into the soil through the sleeve 7, and the sampling head 8 can be taken out of the soil after the sampling head 8 is completely inserted into the soil. A boss is provided on one side of the sleeve 7 to prevent the soil inside the sampling head 8 from being squeezed. At the same time, the inclined platform 10 can reduce the resistance of the sampling head 8 and the sleeve 7 when entering the soil, thereby reducing the influence on the sample bulk density.

[0036] After the sampling head 8 is taken out, the sampling head 8 is inverted on the rotating disk 17, and then the scraper 1 21 is rotated to fit the outer wall of the sampling head 8. When the rotating motor 16 rotates, the soil outside the sampling head 8 is scraped off, and then the scraper 2 23 on the lifting bracket 22 can be rotated to gradually flatten the excess soil at one end of the sampling head 8, and the excess soil is taken out to control the sample weight while preventing changes in the sample bulk density;

[0037] When the driving motor 11 is working, it will drive the two-stage eccentric wheel 15 to rotate through the driving gear 1 13 and the driving gear 2 14 to make the main box 1 vibrate, and drive the sampling head 8 to embed into the ground. The support rod 2 cooperates with the spring 5 to place the device on the ground more stably, and at the same time, it is convenient to insert the sampling head 8 into the ground at a vertical angle to prevent the sampling head 8 from deflecting during sampling, causing the soil to be squeezed and affecting the soil bulk density.

[0038] Embodiment 2:
