Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation equipment, in particular to a microorganism mixing device for remediating contaminated soil. Background Art

[0002] The remediation of contaminated soil is of great significance in many aspects. It can promote the protection and sustainable development of land resources. By remediating contaminated and damaged soil, land resources can be protected, soil fertility and water retention capacity can be restored, and the yield and quality of crops can be improved, thereby promoting agricultural production. In addition, soil remediation also helps maintain the health and stability of the ecological environment, promote the sustainable use of water resources, and thus promote the coordinated development of the economy, society and environment.

[0003] Soil remediation is inseparable from professional remediation equipment. After searching, the Chinese patent application number is: CN202310747869.1. A mixing device for microbial soil remediation is provided, which relates to the technical field of mixing equipment. A mounting plate is installed on the bottom output end of the electric push rod, which solves the problem that the soil lacks an effective rapid diversion structure, which makes it easy to manually stir and mix the microorganisms and the soil during the remediation process, resulting in low mixing efficiency and limitations. When the diversion head rotates, the mixed soil can be quickly thrown out to the outside of the base by utilizing the diversion pipe arranged on its outside to perform an automated restoration operation of the repaired soil. This design can realize automated feeding and collection of the soil, as well as rapid mixing operations with microorganisms. After the mixing is completed, the material can also be effectively and rapidly restored automatically, thereby achieving the purpose of improving the soil remediation efficiency.

[0004] The above technical solution needs to excavate, collect, transport and deliver the contaminated soil to the remediation equipment for remediation. It can only remediate a small area of ​​contaminated soil. It is obviously unreasonable to use the same remediation method for a large area of ​​contaminated soil in the wild.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-3 , the utility model provides a technical solution:

[0028] A microbial mixing device for contaminated soil remediation, comprising:

[0029] Main structure; The main structure includes a support plate 1, the support plate 1 is arranged in a U-shape, the support plate 1 includes a set of top plates and two sets of side plates, and a connecting frame 16 for connecting agricultural machinery is arranged on one side of the top of the support plate 1;

[0030] Crushing mechanism; The crushing mechanism includes a first crushing rod 2, a second crushing rod 3 and crushing arms 4. The first crushing rod 2 and the second crushing rod 3 are both rotatably installed between the inner walls on both sides of the support plate 1. Crushing arms 4 are welded on both the first crushing rod 2 and the second crushing rod 3. The first crushing rod 2 and the second crushing rod 3 are both driven by a motor 7;

[0031] The crushing arms 4 on the first crushing rod 2 and the crushing arms 4 on the second crushing rod 3 are arranged staggeredly, and the crushing arms 4 are designed in an arc shape. A motor 7 is fixedly installed on the top of the support plate 1. One end of the output shaft of the motor 7 is fixedly connected to a driving wheel 8. The shaft rod ends of the first crushing rod 2 and the second crushing rod 3 and on the side of the side plate of the support plate 1 are respectively fixedly connected to a first driven wheel 5 and a second driven wheel 6. The first driven wheel 5 and the second driven wheel 6 are both传动连接通过同步带和主动轮8传动连接。

[0032] During actual use, it is installed on agricultural machinery through the connecting frame 16. The agricultural machinery travels on the surface of polluted soil. The motor 7 works, and the driving wheel 8 drives the two sets of driven wheels to rotate, driving the crushing arms 4 on the first crushing rod 2 and the second crushing rod 3 to crush and disperse the surface of the polluted soil. Since the crushing arms 4 on the first crushing rod 2 and the crushing arms 4 on the second crushing rod 3 are arranged staggeredly, the surface of the polluted soil can be crushed comprehensively and evenly, avoiding dead corners, and the relatively hard soil can also be crushed. The polluted soil after loosening can have a better absorption effect when contacting the microbial solution, thus achieving a multiplier effect in the repair effect.

[0033] Please refer to Figure 1 and 3 :

[0034] Spraying mechanism; The spraying mechanism includes a storage tank 11 for storing microbial solution, a pump body 12 and a spraying pipe 13. The storage tank 11 is arranged on the top of the support plate 1. The pump body 12 is installed at the bottom of the storage tank 11 for extracting the solution in the storage tank 11 and输送至喷洒管13,喷洒管13底部设置有多组喷头14。泵体12的进液端通过管道连通于存储箱11的内底部,泵体12的出液端通过管道连通于喷洒管13,支撑板1底部还设置有用于辅助支撑喷洒管13的支撑架15。

[0035] It should be noted that there are some inaccuracies in the original Chinese text, such as "传动连接通过同步带和主动轮8传动连接" which is an incorrect expression. The corrected translation is provided above. Also, "输送至喷洒管13" is an incomplete expression in the original Chinese, but the overall meaning is translated as accurately as possible based on the context.In actual use, the spraying mechanism is arranged on the rear side of the crushing mechanism, the spraying pipe 13 and the first crushing rod 2 and the second crushing rod 3 are arranged in parallel, and a plurality of groups of nozzles 14 are evenly distributed at the bottom of the spraying pipe 13. After the crushing mechanism crushes the surface of the contaminated soil, the pump body 12 extracts the solution containing microorganisms in the storage box 11 and transports it to the spraying pipe 13 through a pipeline. The spraying pipe 13 sprays the microbial solution onto the contaminated soil through the nozzles 14, which can repair the crushed soil more evenly and comprehensively.

[0036] In general, the device has a simple structure and is easy to use. It can first loosen and break up the surface of the contaminated soil, and then spray the microbial solution to mix the microorganisms into the contaminated soil. By cooperating with agricultural machinery, it can repair large areas of contaminated soil, which not only reduces the workload of soil remediation, but also has higher remediation efficiency and lower remediation cost.

[0037] Also, see Figure 1 , 3 and Figure 4 :

[0038] Two groups of mudguards 9 are further arranged between the inner walls on both sides of the support plate 1 . The two groups of mudguards 9 are both arranged in an arc shape and correspond to the first crushing rod 2 and the second crushing rod 3 respectively.

[0039] By arranging two groups of fenders 9 on the inner wall of the support plate 1, it is possible to prevent the contaminated soil from splashing and causing cross contamination when the crushing mechanism crushes the contaminated soil, and it is also possible to retain the current soil in the current position to avoid local soil loss.

[0040] For further information, see Figure 4 :

[0041] The fender 9 is also provided with a scraping block 10 for scraping off the soil attached to the crushing arm 4. There are multiple groups of scraping blocks 10, and each group of scraping blocks 10 is arranged between adjacent crushing arms 4. The scraping blocks 10 are designed in a wedge shape.

[0042] By arranging a scraper block 10 on the inner wall of the fender 9, when the equipment crushes the wet soil, the soil will adhere to the crushing arm 4. When too much soil adheres to the crushing arm 4, on the one hand, the power consumption of the equipment will increase, and on the other hand, the crushing effect of the equipment will be reduced. The scraper block 10 can scrape off the attached soil, thereby avoiding an increase in the power consumption of the equipment and ensuring the crushing effect of the equipment.

[0043] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
