Description

Technical Field

[0001] The invention belongs to the technical field of soil heavy metal monitoring, and in particular relates to a soil heavy metal monitoring device. Background Art

[0002] The quality and safety of plants are closely related to the soil environment of the production area. Heavy metals generally enter the soil and accumulate first. Plants absorb and accumulate heavy metals from the soil through their roots. Sometimes they also absorb gaseous or dusty heavy metal elements from the air through the stomata on the leaves. In recent years, due to the large-scale application of pesticides, fertilizers, and growth hormones and the pollution of industrial "three wastes", the content of heavy metals in the soil in the planting area has exceeded the standard seriously and widely. This not only poisons the soil and plant system and reduces the quality of plants, but also pollutes surface water through runoff and leaching. What is more important is that they enter the human body through the food chain. The enriched heavy metals are difficult for the human body to metabolize, and ultimately directly or indirectly endanger the health of human organs.

[0003] In the soil heavy metal monitoring device, the analyzer is one of the essential components, which can be divided into large laboratory analyzers and portable small analyzers. Large laboratory analyzers require soil sampling, screening, drying and other pre-treatments before testing. Although small analyzers are more portable, they cannot pre-treat the soil, and the detection accuracy is quite different.

[0004] At present, when small analyzers are used, the soil cannot be pretreated, and it is difficult to ensure the accuracy of heavy metal analysis. When high-precision data is needed, soil samples need to be taken and transported to the laboratory for testing. This not only wastes time and slows down the efficiency of testing, but also increases the cost of testing. It cannot guarantee the timeliness of the test and is not conducive to long-term use by users.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] like Figures 1 to 10 As shown, a soil heavy metal monitoring device in an embodiment of the present invention includes: a small analyzer body 1, a screening and processing mechanism 2, a vibration enhancement mechanism 3, an impact separation mechanism 4 and a screening and blowing mechanism 5.

[0021] like Figures 1 to 8 As shown, a screening and processing mechanism 2 is fixedly installed on one side of the small analyzer body 1 for screening the soil.

An exhaust net is fixedly installed on the screening and processing chamber 201 to facilitate the discharge of air and provide an air duct for air circulation, so that the air will not carry dust and stay in the screening and processing chamber 201.

[0022] Among them, a screening processing frame 202 is provided in the screening processing bin 201, which can screen the soil. Suitable soil will follow the guidance of the screening processing frame 202 and fall on the screening blast bin 501, while dust that is too fine will be screened and discharged through airflow or the screening partition plate 211.

[0023] In addition, a screening processing shaft 203 is provided on one side of the screening processing grid 202, which can fix the position of the screening processing rubber membrane 204, thereby improving the stability of the screening processing rubber membrane 204. The screening processing rubber membrane 204 is installed between the screening processing shaft 203 and the screening processing grid 202, and the position of the screening processing grid 202 can be fixed by the connection of the screening processing shaft 203. When the screening processing grid 202 shakes, the screening processing shaft 203 will rotate synchronously, and the screening processing rubber membrane 204 will slightly expand and contract, and the screening processing rubber membrane 204 has a certain elasticity.

[0024] In addition, a screening processing measuring cup 205 is provided in the screening processing bin 201 , which can collect the soil and quantify the soil according to the capacity of the screening processing measuring cup 205 .

[0026] In addition, a screening rotation spring 207 is installed between the screening support bin 206 and the screening processing shaft 203, which can rotate the screening processing shaft 203 and provide a corresponding supporting effect for the screening processing grid 202.

[0027] like Figures 1 to 7 As shown, the screening processing shaft 203 is arranged to penetrate the screening support bin 206 , which facilitates the installation of the screening return spring 207 , improves the stability of the screening processing shaft 203 , and improves the balance of the screening processing shaft 203 .

[0030] Among them, a screening scraper 210 is fixedly installed on the screening processing chamber 201, which can scrape the soil in the screening processing measuring cup 205, so that the soil in the screening processing measuring cup 205 is quantitative each time it is filled, ensuring the quantitative demand of the small analyzer body 1 for soil detection.

[0031] In addition, a screening partition plate 211 is fixedly installed in the screening processing bin 201, which can block the overly fine soil screened on the screening processing grid 202, reduce the possibility of soil directly entering the screening processing measuring cup 205, and ensure the reliability of the soil in the screening processing measuring cup 205.

[0032] like Figures 1 to 7 As shown, a vibration enhancement mechanism 3 is installed on the side of the screening processing frame 202 away from the screening processing rubber membrane 204, which is used to improve the screening effect of the soil. The vibration enhancement mechanism 3 includes a vibration enhancement frame 301, which can drive the vibration of the screening processing frame 202 by connecting with the screening processing frame 202, and can vibrate due to the impact of the vibration enhancement cam 302.

[0033] In addition, a vibration enhancement cam 302 is provided on the upper side of the vibration enhancement frame 301, which can regularly knock on the vibration enhancement frame 301. A vibration enhancement rotating shaft 303 is fixedly installed in the vibration enhancement cam 302, which can drive the rotation of the vibration enhancement cam 302 and fix the position of the vibration enhancement cam 302. A vibration enhancement ball 304 is rotatably installed on the vibration enhancement cam 302, which can reduce the friction between the vibration enhancement cam 302 and the vibration enhancement frame 301, thereby improving the service life of the vibration enhancement cam 302 and the vibration enhancement frame 301.

[0034] like Figures 1 to 8 As shown, the vibration enhancement shaft 303 is rotatably connected to the screening processing bin 201, so that the vibration enhancement shaft 303 can rotate when driven, and can drive the rotation of the vibration enhancement cam 302, so that the vibration enhancement cam 302 can regularly collide with the vibration enhancement frame 301.

[0035] A vibration efficiency enhancement sliding column 305 is provided at the lower side of the vibration efficiency enhancement frame 301 , which can facilitate the lifting and lowering of the vibration efficiency enhancement support column 306 , so that the vibration efficiency enhancement support column 306 can better support the vibration efficiency enhancement frame 301 .

[0036] In addition, a vibration enhancement support column 306 is slidably installed in the vibration enhancement sliding column 305, which can support the vibration enhancement frame 301 and reduce the damage to the vibration enhancement frame 301. An abutment plate is provided at the lower end of the vibration enhancement support column 306, and a sealing ring is provided on the periphery of the abutment plate. The sealing ring is tightly abutted against the inner wall of the vibration enhancement sliding column 305. The inner cavity of the vibration enhancement sliding column 305 below the vibration enhancement support column 306 is filled with compressed air, and the vibration enhancement support column 306 can be rebound supported by the compressed air. In other embodiments, a spring is provided in the vibration enhancement sliding column 305 below the vibration enhancement support column 306, and the upper end of the spring is connected to the bottom of the vibration enhancement support column 306, and the vibration enhancement support column 306 can be elastically supported by the spring.

[0037] In addition, a number of vibration anti-wear balls 307 are rotatably installed on the vibration enhancement support column 306. When displacement occurs between the vibration enhancement frame 301 and the vibration enhancement support column 306, the vibration anti-wear balls 307 can reduce the friction between the vibration enhancement frame 301 and the vibration enhancement support column 306, thereby improving the stability of the vibration enhancement frame 301.

[0038] like Figures 1 to 9 As shown, an impact segmentation mechanism 4 is fixedly installed in the screening processing chamber 201 for improving the screening efficiency of the soil. The impact segmentation mechanism 4 includes an impact segmentation chamber 401, which can fix the position of the impact segmentation grid 402 and provide corresponding space for striking the soil.

[0039] Among them, an impact and separation grid frame 402 is fixedly installed on the lower side of the impact and separation chamber 401. After the soil enters the impact and separation chamber 401, it will be cut and knocked by the impact and separation knife group 403. After the agglomerated soil is broken, the processed soil can pass through the impact and separation grid frame 402 and fall on the screening processing grid frame 202.

[0040] In addition, an impact-splitting knife group 403 is rotatably installed in the impact-splitting chamber 401, which can knock and cut the soil, so that the agglomerated soil can be broken up and the impact-splitting grid frame 402 can be used.

[0041] In addition, an impact filling bin 404 is provided on the screening processing bin 201 for the user to fill the soil. After sampling the soil, the user fills the soil into the impact filling bin 404. The impact filling bin 404 and the impact segmentation knife group 403 are both arranged through the impact segmentation bin 401.

[0042] like Figures 1 to 5 As shown, an impact motor 405 is fixedly installed in the screening processing bin 201, which can drive the rotation of the first active leather wheel 406 and the second active leather wheel 409, and provide corresponding power for the rotation of the first active leather wheel 406 and the second active leather wheel 409.

[0043] Among them, a first active leather pulley 406 is fixedly installed on the impact motor 405, which can drive the rotation of the first driven leather pulley 407 through the first belt 408, and then drive the rotation of the impact and segmentation knife group 403. A first driven leather pulley 407 is fixedly installed on the impact and segmentation knife group 403, and a first belt 408 is installed between the first active leather pulley 406 and the first driven leather pulley 407.

[0044] like Figures 1 to 6 As shown, a second driving pulley 409 is fixedly installed on one side of the first driving pulley 406, which can drive the rotation of the second driven pulley 410 through the second belt 411, thereby making the vibration enhancement shaft 303 rotate synchronously, so that the vibration enhancement cam 302 regularly strikes the vibration enhancement frame 301, and a second driven pulley 410 is fixedly installed on the vibration enhancement shaft 303, and a second belt 411 is installed between the second driving pulley 409 and the second driven pulley 410.

[0045] like Figures 1 to 8 As shown, a screening and blowing mechanism 5 is fixedly installed in the screening processing bin 201, which is used to screen the soil and dry the screened soil. The screening and blowing mechanism 5 includes a screening and blowing bin 501, which can accommodate air and provide corresponding space for the air, and provides space for the screening heating wire 503 to heat the air.

[0046] Among them, a screening blower 502 is fixedly installed in the screening blast chamber 501, which can extract air from the outside and inject the air into the screening blast chamber 501. The screening blower 502 is set throughout the screening blast chamber 501 and the screening processing chamber 201.

[0047] In addition, a screening electric heating wire 503 is fixedly installed in the screening blast chamber 501, which can heat the air so that the air can dry the soil after being blown out.

[0048] like Figures 1 to 4 As shown, a plurality of evenly distributed screening exhaust pipes 504 are installed on the upper wall of the screening blast bin 501, which can guide the soil falling on the screening blast bin 501 while ventilating, accelerate the speed of soil descent, and improve the screening efficiency. The screening electric heating wire 503 is located between the screening exhaust pipe 504 and the air outlet of the screening blower 502.

[0049] In addition, the screening exhaust duct 504 runs through the screening blast chamber 501 and can blow air on the overly fine soil so that the overly fine soil is discharged with the air. Even if it is not discharged, the probability of entering the screening processing measuring cup 205 will be reduced.

[0050] Among them, a screening guide 505 is fixedly installed on one side of the screening and blowing chamber 501 close to the screening and processing measuring cup 205, which can guide the screened soil so that the screening and processing measuring cup 205 can better collect the soil.

[0051] During specific use, before the user detects the soil through the small analyzer body 1, he first takes a sample and fills the soil to be tested into the impact filling bin 404. The soil will first enter the impact segmentation bin 401, and the rotation of the impact segmentation knife group 403 will break up the lumps in the soil. Then, the soil will fall onto the screening processing grid 202 through the impact segmentation grid 402.

[0052] At this time, the vibration enhancement cam 302 hits the vibration enhancement frame 301, which transmits the vibration to the screening processing frame 202. The soil is screened by the screening processing frame 202, and the dust that is too fine will fall directly and be discharged under the influence of air and the screening partition plate 211. The suitable soil will fall on the screening blast chamber 501 through the combined effect of the inclination and vibration of the screening processing frame 202.

[0053] At the same time, the screening blower 502 draws in external air, heats the screening electric heating wire 503, and discharges it through the screening exhaust pipe 504. While drying the soil in the screening processing bin 201, the fine dust can be carried away and discharged through the airflow, and suitable soil will enter the screening processing measuring cup 205. When the user takes the screening processing measuring cup 205, the excess soil will be scraped off through the guidance of the screening sliding frame 208 and the friction of the screening scraper 210, so that the soil in the screening processing measuring cup 205 can be quantified, meeting the detection requirements of the small analyzer body 1, and improving the accuracy of the small analyzer body 1.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
