Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a rapid screening soil particle processing device. Background Technology

[0002] Soil particle size distribution is one of the most fundamental physical properties of soil. In practical applications, accurately obtaining soil particle size distribution data requires first performing particle sieving on soil samples, that is, separating the soil sample into several components according to different particle size ranges. Traditional manual sieving methods are not only labor-intensive and time-consuming, but the sieving results are also easily affected by the subjective factors and skill level of the operators, making it difficult to guarantee sieving accuracy and consistency. With the increasing demands for efficiency and accuracy in soil particle analysis from modern agriculture, engineering construction, and environmental science, developing a device capable of automatically sieving soil particles has become an inevitable trend to meet practical needs and provide a reliable sample basis for subsequent soil particle size distribution analysis.

[0003] In existing technologies, automatic soil particle composition screening typically employs vibrating screening or rotary agitation. Based on the size of the soil particles, different mesh sizes are used for particle size classification and screening, completing the automatic grading and screening operation. However, in actual screening processes, while existing vibrating screening can quickly screen materials, and the agitating screen prevents soil particles from clogging the mesh, the vibration energy generated when the vibrating mechanism is activated interferes with the stable rotation of the rotating agitator plate. This causes fluctuations in the rotation speed and deviation in the rotation trajectory, making it impossible to evenly agitate and disperse the soil particles on the screen plate. This method is not well compatible with both vibrating screening and agitating screening, lacking practicality. It also lacks convenience in rapid screening and filtration to prevent clogging, resulting in generally low screening efficiency and quality, affecting the accuracy of subsequent soil particle composition analysis results. Therefore, we propose a rapid screening soil particle processing device to solve these problems. Utility Model Content

Bottom material discharge pipes 202 are provided at the bottom of the side of the screening cylinder 2.

[0041] Specifically, the outer side of the screening cylinder 2 is provided with equal-distance discharge pipes 201, which can discharge soil particles filtered by multiple particle screening screens 6 in sequence. During the mixing, the discharge pipes 201 are covered by a cover plate on the side. After screening is completed, the cover plate can be removed and the soil particles can be discharged through the discharge pipes 201 for subsequent testing. The bottom of the side of the screening cylinder 2 is provided with a bottom discharge pipe 202, which can quickly discharge the impurities remaining at the bottom of the screening cylinder 2, making discharge convenient.

[0042] Furthermore, the rotating scraper 7 includes a central support column 701, scraper 702, and U-shaped bracket 703. The U-shaped bracket 703 is fixedly installed on the bottom inner side of the bearing bracket 1. The central support column 701 is rotatably connected to the inner side of the U-shaped bracket 703.

The rubber shock absorber 9 is sleeved and rotated on the central support column 701.

[0043] Specifically, the axial support column 701 can be driven to rotate by the drive motor 8, which facilitates the rotation of the scraper plates 702 on both sides. The scraper plates 702 are in contact with the top of the particle screening screen 6 and the inner bottom wall of the screening cylinder 2. When the scraper plates 702 rotate, they can stir and scrape the soil particles on the top of the particle screening screen 6, which has a good anti-clogging effect. The scraper plates 702 at the bottom can scrape off the soil particles remaining on the inner bottom wall of the screening cylinder 2, preventing the residue of soil and impurities in the screening cylinder 2. The discharge is convenient and the use effect is good. The U-shaped bracket 703 is installed on the inner bottom wall of the bearing bracket 1, which can support the axial support column 701. The rotation of the axial support column 701 remains stable and is not easy to tilt.

[0044] Furthermore, the rubber-type shock absorber 9 includes a rotating rubber cylinder 901, a mounting rubber ring 902, and an annular anti-leakage plate 903. Multiple rotating rubber cylinders 901 are equidistantly sleeved on the rod of the rotating scraper 7. Multiple mounting rubber rings 902 are respectively fixedly installed on the inner ring of the particle screening screen 6 and the bottom of the screening cylinder 2. The annular anti-leakage plate 903 is fixedly installed between adjacent rotating rubber cylinders 901 and mounting rubber rings 902.

[0045] Specifically, multiple rotating rubber cylinders 901 are equidistantly installed on the central support column 701, and multiple mounting rubber rings 902 are correspondingly installed on the inner ring of the particle screening mesh 6 and the bottom of the screening cylinder 2. The annular anti-leakage plate 903 is sealed between adjacent rotating rubber cylinders 901 and mounting rubber rings 902, playing a sealing and closing role. When the central support column 701 rotates, the rotating rubber cylinders 901 maintain a supporting and positioning role, playing a sealing role and preventing soil leakage and falling. At the same time, the mounting rubber rings 902 are installed on the outside and are flexibly connected by the annular anti-leakage plate 903, which can shield the soil while playing a vibration isolation role. Vibration is not easily transmitted and damages the rotating scraper 7, thus taking into account both vibrating screening and agitating screening.

[0046] Furthermore, the number of rotating rubber cylinders 901, mounting rubber rings 902, and annular anti-leakage plates 903 are equal, and a sealed bearing is provided at the connection between the rotating rubber cylinders 901 and the rotating scraper 7. Adjacent rotating rubber cylinders 901, mounting rubber rings 902, and annular anti-leakage plates 903 are integrated and connected.

[0047] Specifically, the number of rotating rubber cylinders 901, mounting rubber rings 902, and annular anti-leakage plates 903 are equal, which can stably play an isolation role, prevent vibration damage to the rotating scraper 7, and provide good load-bearing protection. Furthermore, the adjacent rotating rubber cylinders 901, mounting rubber rings 902, and annular anti-leakage plates 903 are integrated and connected, resulting in good sealing and excellent leak-proof capability. The sealed bearing is installed at the connection between the rotating rubber cylinders 901 and the rotating scraper 7, which facilitates the stable rotation of the rotating scraper 7 and ensures stable load-bearing rotation.

[0048] Furthermore, the closing cover plate component 10 includes a cross mounting bracket 1001, an elastic spring 1002, and a sealing cover plate 1003. The four corners of the cross mounting bracket 1001 are hinged with mounting buckles 1004.

The two ends of the elastic spring 1002 are fixedly installed between the cross mounting bracket 1001 and the sealing cover plate 1003. The sealing cover plate 1003 is sleeved and sealed to the top of the screening cylinder 2. The cross mounting bracket 1001 is located directly below the sealing cover plate 1003.

[0049] Specifically, the four corners of the cross mounting bracket 1001 can be hinged to mounting buckles 1004. The cross mounting bracket 1001 is mounted on the support bracket 101 by the mounting buckles 1004. The cross mounting bracket 1001 can be elastically supported by the sealing cover plate 1003 by the elastic spring 1002. When the sealing cover plate 1003 is sleeved on the top of the screening cylinder 2, it can be elastically squeezed by the elastic spring 1002. Thus, when the screening cylinder 2 vibrates and screens, the elastic spring 1002 can play a vibration damping and protection role. The elastic spring 1002 can also elastically abut against the cross mounting bracket 1001 in the opposite direction, so that the cross mounting bracket 1001 and the mounting buckles 1004 can be tightly abutted and snapped on the support bracket 101, and the installation is stable.

[0050] How to use and how to work this device:

[0051] By uniformly setting vibration damping buffers 3 at the bottom of the inner side of the support bracket 1, it is easy to elastically support the annular support seat 4. Vibration motors 5 are installed on both sides of the bottom of the annular support seat 4. When the vibration motors 5 drive the annular support seat 4 to vibrate, the vibration damping buffers 3 can play a resonance and buffering role, and play an isolation and vibration reduction role for the support bracket 1. The top of the annular support seat 4 is equipped with a screening cylinder 2. When soil is introduced into the screening cylinder 2, the screening operation can be carried out in a vibratory manner.

[0053] A drive motor 8 is embedded in the bottom of the inner side of the support bracket 1. A rotating scraper 7 is rotatably connected inside the screening cylinder 2. The scraper plates 702 on both sides of the rotating scraper 7 correspond to the top of the granular screen 6 and the bottom of the screening cylinder 2. The drive motor 8 can drive the rotating scraper 7 to rotate, which drives the scraper plates 702 to stir and scrape the soil particles on the top of the granular screen 6. The screen holes of the granular screen 6 are not easy to be blocked and have good scraping effect. The bottom wall of the screening cylinder 2 is not easy to be left with residue, and the discharge is convenient. A rubber shock absorber 9 is provided between the rotating scraper 7, the granular screen 6 and the screening cylinder 2. This makes the rotating scraper 7 less susceptible to the vibration of the granular screen 6 and the screening cylinder 2 when it is rotating and stirring. The rubber shock absorber 9 is a closed elastic connection, which plays a role in vibration isolation. Vibration is not easy to be transmitted and damage the rotating scraper 7. Thus, it takes into account both vibration screening and stirring screening, with high screening efficiency and excellent screening quality.

[0056] The outer side of the screening cylinder 2 is provided with equal-distance discharge pipes 201, which can discharge soil particles filtered by multiple particle screening screens 6 in sequence. During the mixing, the discharge pipes 201 are covered by a cover plate on the side. After screening is completed, the cover plate can be removed and the soil particles can be discharged through the discharge pipes 201 for easy subsequent testing. The bottom of the side of the screening cylinder 2 is provided with a bottom discharge pipe 202, which can quickly discharge the impurities remaining at the bottom of the screening cylinder 2, making discharge convenient.

[0057] The rotating scraper component 7 includes a central support column 701, a scraper plate 702, and a U-shaped bracket 703. The central support column 701 can be driven to rotate by a drive motor 8, which facilitates the rotation of the scraper plates 702 on both sides. The scraper plates 702 are in contact with the top of the granular screen 6 and the inner bottom wall of the screening cylinder 2. When the scraper plates 702 rotate, they can stir and scrape the soil particles at the top of the granular screen 6, which has a good anti-clogging effect. The scraper plates 702 at the bottom can scrape and discharge the soil particles remaining on the inner bottom wall of the screening cylinder 2, preventing the residue of soil and impurities in the screening cylinder 2. The discharge is convenient and the use effect is good. The U-shaped bracket 703 is installed on the inner bottom wall of the bearing bracket 1, which can support the central support column 701.

[0058] The rubber-type shock absorber 9 includes a rotating rubber cylinder 901, a mounting rubber ring 902, and an annular anti-leakage plate 903. Multiple rotating rubber cylinders 901 are equidistantly installed on the axial support column 701, and multiple mounting rubber rings 902 are correspondingly installed on the inner ring of the particle screening screen 6 and the bottom of the screening cylinder 2. The annular anti-leakage plate 903 is sealed between adjacent rotating rubber cylinders 901 and mounting rubber rings 902, playing a sealing and closing role. When the axial support column 701 rotates, the rotating rubber cylinders 901 maintain a supporting and positioning role, playing a sealing role and preventing soil leakage and falling. At the same time, the mounting rubber rings 902 are installed on the outside and are flexibly connected by the annular anti-leakage plate 903, which can shield the soil while playing a vibration isolation role. Vibration is not easily transmitted and damages the rotating scraper 7, thus taking into account both vibrating screening and agitating screening.

[0059] The number of rotating rubber cylinders 901, mounting rubber rings 902, and annular anti-leakage plates 903 are equal, which can stably play an isolation role, prevent vibration damage to the rotating scraper 7, and provide good load-bearing protection. Furthermore, the adjacent rotating rubber cylinders 901, mounting rubber rings 902, and annular anti-leakage plates 903 are integrated and connected, resulting in good sealing and excellent leak-proof capability. The sealed bearing is installed at the connection between the rotating rubber cylinders 901 and the rotating scraper 7, which facilitates the stable rotation of the rotating scraper 7 and ensures stable load-bearing rotation.

[0060] The closing cover plate component 10 includes a cross mounting bracket 1001, an elastic spring 1002, and a sealing cover plate 1003. The four corners of the cross mounting bracket 1001 can be hinged to mounting buckles 1004. The cross mounting bracket 1001 is mounted on the support bracket 101 by the mounting buckles 1004. The cross mounting bracket 1001 can elastically support the sealing cover plate 1003 by the elastic spring 1002. When the sealing cover plate 1003 is sleeved on the top of the screening cylinder 2, it can be elastically squeezed by the elastic spring 1002. Thus, when the screening cylinder 2 is vibrating and screening, the elastic spring 1002 can play a vibration damping and protection role. The elastic spring 1002 can also elastically abut against the cross mounting bracket 1001 in the opposite direction, so that the cross mounting bracket 1001 and the mounting buckles 1004 can be tightly abutted and snapped onto the support bracket 101, and the installation and fit are stable.
