Description

Technical Field

[0001] The utility model belongs to the technical field of soil sample separation, and in particular relates to a soil sample fine particle matter separation mechanism for environmental science research. Background Art

[0002] In environmental science research, studying soil samples and accurately analyzing the composition and characteristics of the soil are crucial for understanding soil quality, ecosystem functions, and environmental pollution. The particle size composition of the soil is the ratio of the mass of each particle group in the rock and soil to the total mass of the dry soil. The particle size composition of the soil is affected by its formation conditions. Generally, the particle size of the soil can be divided into coarse particles and fine particles. In order to separate soil particles of different sizes, a separation mechanism is needed.

[0003] Existing separation mechanisms generally use filters for separation, using sieves of different apertures to screen soil samples and separate fine-grained matter from coarse-grained matter. However, before separating the soil samples, in order to facilitate the separation of coarse and fine-grained soil, it is necessary to purchase additional crushing equipment to crush the bulk soil samples, and after crushing and collecting, pour them into the filter for separation, making the entire soil sample separation process more complicated and time-consuming, more troublesome, and greatly reducing the separation efficiency.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0027] The utility model provides Figure 1-5 A soil sample fine particle separation mechanism for environmental science research, comprising:

[0028] A bottom plate 1, the bottom of which is rotatably connected to a plurality of universal wheels 2, and the top of which is connected to a screening box 3;

When the screening plate 4 moves back and forth, the slider 5 at one end thereof slides in the slide groove on the inner wall of the screening box 3, guiding the direction of the movement of the screening plate 4, which can enhance the stability of the screening plate 4 when moving.

[0030] The blanking assembly is arranged on the top of the screening box 3. The threaded blades 8 of the blanking assembly break up the soil samples in block form and transport them between the two sets of pressing rollers 9 in the screening box 3, so that the two rotating sets of pressing rollers 9 crush the soil samples.

[0031] The unloading assembly includes a first motor 10 and a scraper 11. A feeding cylinder 12 is provided on the top of the screening box 3 and a rotating shaft 13 is rotatably connected inside the feeding cylinder 12. The first motor 10 is provided on one side of the feeding cylinder 12 and the output shaft of the first motor 10 rotates through the feeding cylinder 12 and is connected to the rotating shaft 13.

[0032] The threaded blades 8 are connected to the surface of the rotating shaft 13. The bottom of one end of the feeding cylinder 12 is connected to the screening box 3, and the top of the other end is provided with a feeding hopper 14.

[0033] The two sets of pressure rollers 9 are rotatably connected to the screening box 3 through bearings, and two sets of second motors 15 are provided on the surface of the screening box 3. The output shafts of the second motors 15 rotate through the screening box 3 and are connected to the pressure rollers 9.

[0034] The scraper 11 is provided in two groups and is respectively connected to the screening box 3. One end of the scraper 11 contacts the pressure roller 9. The scraper 11 scrapes the surface of the pressure roller 9 to scrape off the soil adhered to the surface of the pressure roller 9 after rolling.

[0035] The screening box 3 is provided with a plurality of sleeves 16 , each of which is slidably connected to a sleeve rod 17 . The other end of the sleeve rod 17 is connected to the screening plate 4 , and a spring 18 is connected between two groups of sleeves 16 and the sleeve rod 17 .

[0036] A protective shell 22 is provided on one side of the screening box 3 and a third motor 19 is provided in the protective shell 22. The output shaft of the third motor 19 rotates through the protective shell 22 and is connected to the turntable 20. A sliding block 21 is connected to the turntable 20, and a rotating plate 23 is rotatably connected to the protective shell 22.

[0037] The rotating plate 23 is provided with a first slide groove 24 and a second slide groove 25. The sliding block 21 is slidably connected to the first slide groove 24. The second slide groove 25 is slidably connected to a connecting block. The other end of the connecting block is fixedly connected to a push rod 26 for pushing the screening plate 4 to move.

A slot 30 is provided on the surface of the screening box 3 and located on one side of the collecting box 29. After the collecting box 29 collects the soil sample, the collecting box 29 is pulled out from the slot 30 to collect the soil sample in the collecting box 29.

[0039] The soil sample fine-grained material separation mechanism for environmental science research pours the soil sample in block form into the feed hopper 14 and starts the first motor 10 and the second motor 15. The first motor 10 drives the rotating shaft 13 to rotate, thereby driving the threaded blades 8 through the rotating rotating shaft 13 to crush the soil sample in the feed cylinder 12 to avoid agglomeration, and under the transportation of the threaded blades 8, the soil sample is transported to one end of the feed cylinder 12 and falls between the two groups of pressing rollers 9, and the two groups of second motors 15 drive the two groups of pressing rollers 9 to rotate in opposite directions to crush the large soil sample between the two groups of pressing rollers 9. After crushing, the large soil sample falls to the surface of the screening plate 4 for separation, and the multiple groups of inclined plates 31 located at the bottom of the pressing rollers 9 in the screening box 3 can guide the falling granular soil to the surface of the screening plate 4.

[0040] The large soil samples are crushed by two sets of rollers 9 to form small soil particles, so that the soil can directly enter the screening plate 4 for separation after crushing.

[0041] When the two sets of pressing rollers 9 roll the soil, the scraper 11 contacts the pressing roller 9 and can scrape the surface of the pressing roller 9 through the scraper 11, so that the crushed soil is scraped off the surface of the pressing roller 9.

[0042] After the small particles of soil sample fall onto the surface of the screening plate 4, the third motor 19 can be started to work, and the third motor 19 drives the turntable 20 to rotate. When the turntable 20 rotates, it slides in the first slide groove 24 on the surface of the rotating plate 23 through the sliding block 21, and drives the rotating plate 23 to rotate. When the rotating plate 23 rotates, it drives the push rod 26 to move, so that the push rod 26 reciprocates to the left or right under the guidance of the guide plate 27, thereby pushing the screening plate 4 to screen the soil sample on its surface through the moving push rod 26. In the process of the screening plate 4 moving to the left, the two sets of sleeve rods 17 away from the third motor 19 slide in the sleeve 16 and compress the spring 18, which can ensure that the moving direction of the screening plate 4 always remains stable. After the push rod 26 is out of contact with the screening plate 4, the spring 18 rebounds and drives the screening plate 4 to reset.

[0043] When the screening plate 4 is screening, the cylinder 6 can be started to work, and the piston rod of the cylinder 6 pushes the brush plate 7 on the surface of the screening plate 4 to move, and the soil sample on the surface of the screening plate 4 can be brushed by the brush on the surface of the brush plate 7. The brushing of the brush can make the soil particles flow more evenly on the surface of the screening plate 4, avoiding local accumulation of soil particles, and the small particles of soil (coarse particles) after screening are retained on the surface of the screening plate 4, and the soil powder particles (fine particles) are screened into the collecting bucket 28, and fall into the collecting box 29 through the collecting bucket 28 for collection, and the collecting box 29 is pulled out from the slot 30 to collect the fine-grained soil samples in the collecting box 29. The coarse-grained soil on the surface of the screening box 3 can be collected by opening the cabinet door hinged on the surface of the screening box 3.
