Description

Technical Field

[0001] This utility model relates to the field of detection and sampling technology, specifically to a biological detection and sampling device. Background Technology

[0002] By detecting soil microbial biomass, we can understand the status of the entire microbial community or some specific populations in the soil, further revealing changes in the farmland ecosystem, as well as the activity of microorganisms in the soil and the rate and intensity of their decomposition of organic matter residues. Currently, the main methods for detecting soil microbial biomass include: direct microscopic examination (plate counting), substrate-induced respiration, component analysis, fumigation culture, and fumigation extraction. Soil sampling is required before conducting soil microbial testing.

[0003] Upon inspection, it was found that in the prior art, Chinese Patent No. CN220304847U, published on January 5, 2024, discloses a biological detection sampler, relating to the field of detection sampler technology. It includes a drive assembly, with a biological detection sampling assembly fixedly connected to the lower surface of the drive assembly. The biological detection sampling assembly includes a motor, with a rotating rod fixedly connected to the output end of the motor. A sampling cylinder is fixedly connected to the lower end face of the rotating rod, and multiple first sampling ports are evenly distributed on the outer surface of the sampling cylinder. In this invention, by setting up a sampling cylinder, first sampling ports, second sampling ports, an arc-shaped groove, a support, a threaded rod, a handle, and an arc-shaped block, the outer side of the sampling cylinder has multiple sampling ports, thereby allowing the collection of soil from different locations. This increases the quantity and diversity of samples, improves the reliability of experimental data, and avoids differences between different samples by collecting soil from different locations in the same sampling cylinder, maintaining experimental consistency.

[0004] The above structure also has the following drawbacks:

[0005] Existing biological detection samplers are inconvenient to adjust during use, and the operation steps for collecting and absorbing materials are relatively cumbersome. This not only increases the operation time but also reduces the sampling efficiency. Therefore, there is an urgent need for a biological detection sampler to overcome the above-mentioned defects. Utility Model Content

[0006] The present invention aims to solve the problems mentioned in the background art by providing a biological detection sampler.

[0007] The specific technical solution is as follows:

[0008] A biological detection sampler includes a lifting assembly, a moving assembly, moving wheels, a third motor, and biological detection sampling components. The moving assembly is disposed within the inner cavity of the lifting assembly. The moving wheels are disposed on both sides of the lifting assembly. The third motor is disposed on the left side of the bottom of the lifting assembly. The biological detection sampling components are disposed on both sides of the moving assembly. The lifting assembly includes a positioning rod, a first threaded rod, a first motor, a first slider, a first slide groove, a second slide groove, a threaded sleeve, a second threaded rod, and a collection box. The moving assembly includes a crossbar, a second motor, a third slide groove, a third threaded rod, and a third slider. The biological detection sampling components include a fixing block, a fourth motor, a sampling cylinder, a cylinder, and a discharge plate.

[0009] In the aforementioned biological detection sampler, the first motor is fixedly installed on both sides of the top of the positioning rod, the first slide groove is opened on both sides of the inner cavity of the positioning rod, and the first slider slides in the inner cavity of the first slide groove.

[0010] In the aforementioned biological detection sampler, the first threaded rod rotates inside the first slider via a thread, and the output shaft of the first motor passes through the inner cavity of the first slide groove and is fixedly connected to the top of the first threaded rod.

[0011] In the aforementioned biological detection sampler, the right side of the third motor is fixedly connected to the bottom of the left side of the positioning rod, the second slide groove is opened inside the positioning rod, and the threaded sleeve slides on both sides of the inner cavity of the second slide groove.

[0012] In the aforementioned biological detection sampler: the second threaded rod rotates inside the threaded sleeve via a thread, the output shaft of the third motor passes through the inner cavity of the second slide groove and is fixedly connected to the left side of the second threaded rod, and the collection boxes are all fixedly installed on both sides of the top of the threaded sleeve.

[0013] In the aforementioned biological detection sampler: the side of the moving wheel that is relatively close to the other side is fixedly connected to the outside of the positioning rod; a crossbar is fixedly installed at the bottom of the first slider; and the second motor is fixedly installed on both sides of the crossbar.

[0014] In the aforementioned biological detection sampler, the third grooves are all located on both sides inside the crossbar, the third slider slides inside the third groove, and the third threaded rod rotates inside the third slider via a thread.

[0015] In the aforementioned biological detection sampler: the output shaft of the second motor passes through the inner cavity of the third slide groove and is fixedly connected to the side of the third threaded rod that is relatively far away from it; a fixing block is fixedly installed on the side of the third slide that is relatively far away from it; and the fourth motor is fixedly installed on the top of the fixing block.

[0017] This utility model has the following beneficial effects:

[0018] The biological detection sampler provided by this utility model adjusts the height of the moving component using a lifting assembly, moves the position of the biological detection sampling component using the moving assembly, and samples the soil using the biological detection sampling component. The inclusion of wheels facilitates the movement of the entire device. During sampling, the second motor is activated, driving the third threaded rod to rotate, which in turn moves the third slider and the fixed block to the designated position. Then, the fourth motor is activated, driving the sampling cylinder to rotate. Following this, the first motor is activated, driving the first threaded rod to rotate, which in turn moves the first slider and the crossbar downwards. The soil is sampled using a sampling tube. After sampling, the first motor is turned on to reset the first threaded rod. When the soil is placed in the inner cavity of the collection box, the third motor is turned on, which drives the second threaded rod to rotate. Under the action of the second threaded rod, the threaded sleeve moves the collection box inward. Finally, the cylinder is turned on, which drives the discharge plate downward, thereby discharging the soil into the inner cavity of the collection box. This method has the advantages of convenient sampling and easy adjustment, solving the problems of inconvenient adjustment and cumbersome operation steps in existing biological detection samplers, which not only increase operation time but also reduce sampling efficiency.

[0044] During sampling, the second motor 22 is turned on, which drives the third threaded rod 24 to rotate, causing the third slider 25 and the fixed block 51 to move to the designated position. Then, the fourth motor 52 is turned on, which drives the sampling cylinder 53 to rotate.
