Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, specifically relating to a portable soil sampler with an assistive structure. Background Technology

[0002] Soil sampling is a crucial foundational task in numerous fields, including soil research, agricultural production, and environmental monitoring. Accurate and efficient acquisition of soil samples is essential for understanding the physical, chemical, and biological properties of soil, assessing soil quality, developing appropriate agricultural fertilization programs, and monitoring environmental pollution. With the expanding scope of research and increasingly stringent requirements for soil samples, the development of a portable, easy-to-operate soil sampler that ensures sample quality is particularly urgent.

[0003] Simple manual samplers are a common type of existing soil sampling tool, typically made of a simple metal tube, possibly with a cutting edge at the bottom. Operators need to insert it directly into the soil by hand and then pull it out to obtain the sample. Relying entirely on manual labor to insert the sampler into the soil, especially in harder soils, requires considerable effort, resulting in low work efficiency and fatigue over prolonged operation. After pulling the sampling tube out of the soil, the soil sample often becomes tightly stuck inside, making it difficult to remove intact and easily causing sample loss or damage. Samples obtained in this way require specially designed sample storage and protection devices to prevent the sample from being easily affected by external factors during transfer and transportation, leading to a decline in sample quality; the setup is cumbersome and complex.

[0004] In view of this, we propose a portable soil sampler with an assistive structure to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problem in the prior art where manual samplers require operators to insert them directly into the soil by hand and then pull them out to obtain samples. This relies entirely on manual labor to insert the sampler into the soil, which requires a lot of effort and results in low work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable soil sampler with a assisted structure includes:

[0008] The sampling tube is used to sample the soil. The outer side of the bottom port of the sampling tube has a spiral cutting edge, the top of the sampling tube is equipped with a limiting ring, and the inside of the sampling tube is equipped with a push plate for ejecting the sample.

[0009] The assist frame is used to assist the sampling tube in sampling and to assist the pusher plate in pushing out the sample. The assist frame includes a foot pedal, a telescopic assist rod and an assist pusher.

[0010] A storage box is used to store the collected samples, and the storage box is detachably attached to the bottom of the foot pedal.

[0011] Preferably, the push rod passes through the insertion hole at the top of the sampling tube and is then fixedly connected to the push plate.

[0012] Preferably, the retractable assist rod is fixed to the top of the foot pedal, and a guide plate is fixed on the outer tube of the retractable assist rod, with guide holes provided on the guide plate.

[0013] Preferably, the push rod passes through the guide hole and has an auxiliary pedal fixed at its top. The outer side of the push rod, above the guide plate, has a limiting ring that limits the downward stroke of the push rod when it pushes the push plate downward. The limiting ring is positioned above the guide plate.

[0014] Preferably, the top of the retractable assist rod is equipped with a non-slip handle.

[0015] Preferably, the storage box is provided with several annular slots for inserting and placing sample storage tubes. The annular slots at the front end of the storage box are vertically aligned with the sampling tubes. After the storage box is connected to the foot pedal, the sampling tubes are inserted into the sample storage tubes in the annular slots at the front end of the storage box.

[0016] Preferably, the storage box is fastened to the bottom of the foot pedal by a latch.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are:

[0018] This portable soil sampler with an assistive mechanism consists of a sampling tube, an assistive frame, and a storage box. During operation, first remove the assistive frame and sampling tube from the storage box. Place the sampling tube on the surface of the soil to be sampled. Press the foot pedal to allow the sampling tube to cut into the soil using its bottom spiral cutting edge. The soil pushes against the push plate, causing the assistive push rod to move upwards, and the soil enters the sampling tube, completing the sampling. Afterwards, remove the assistive frame and sampling tube, connect the foot pedal to the storage box, and press the auxiliary pedal to allow the assistive push rod to push the push plate downwards, pushing the soil sample from the sampling tube into the sample storage cylinder in the annular slot at the front of the storage box. The sample storage cylinder can be replaced if different samples are needed.

[0019] The storage box is detachably connected to the foot pedal via a latch. When not in use, it combines with the support frame and sampling tube to form a compact unit, facilitating transport and storage while minimizing space occupation. It provides a sealed environment for the sample, preventing external factors from affecting it and ensuring sample integrity and accuracy. After sampling, the storage box can be directly connected to the foot pedal for sample transport, reducing transfer operations and minimizing sample loss and contamination risks. The internal annular slot can accommodate multiple sample storage tubes for convenient sample classification and storage, and the front annular slot corresponds to the sampling tube, ensuring smooth sample transfer.

[0020] The spiral cutting edge at the bottom of the sampling tube can cut and break up the soil, reducing insertion resistance and improving sampling efficiency. The top limiting ring is inserted into the foot pedal insertion slot and screwed in with bolts to ensure connection stability, prevent shaking and displacement during sampling, and ensure accurate sampling. It also facilitates the replacement of sampling tubes of different specifications or damage.

[0021] The assistive push rod passes through the sampling tube and connects to the push plate. Together with the retractable assistive rod and auxiliary pedal, it utilizes leverage and telescopic functionality to reduce the labor intensity of operators pushing the sample out. The guide plate and guide hole guide the assistive push rod, ensuring vertical movement, while the limit ring prevents the push plate from excessively descending and damaging components. The non-slip handle at the top of the retractable assistive rod increases operating comfort and can be adjusted in length to suit different scenarios. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The following combination Figures 1 to 6 This application will be described in further detail.

[0035] This application discloses a portable soil sampler with an assistive structure, including a sampling tube 1, an assistive frame 2, and a storage box 3. The sampling tube 1 is used to sample the soil, and the inside of the sampling tube 1 is provided with a push plate 211 for ejecting the sample. The assistive frame 2 is used to assist the sampling tube 1 in sampling and to assist the push plate 211 in ejecting the sample. The storage box 3 is used to store the sample, and the storage box 3 is provided with a sample storage cylinder 302 for storing soil samples. The storage box 3 is detachably connected to the bottom of the foot pedal 201. Specifically, the storage box 3 is fastened to the bottom of the foot pedal 201 by a latch 4.

[0036] When not in use, the storage box 3 can be combined with the support frame 2 and sampling tube 1 to form a relatively compact unit, making it easy to carry and store while minimizing space occupation. For example, during field operations, workers can easily take it with them. The storage box 3 provides a relatively enclosed environment for the sampled soil, preventing the sample from being affected by external factors (such as dust, moisture, and impact), thus ensuring the integrity and accuracy of the sample. After sampling, the storage box 3 can be directly installed onto the foot pedal 201 to transport the sample to the laboratory for analysis without additional transfer operations, reducing the risk of sample loss and contamination.

[0037] The power assist frame 2 includes a foot pedal 201, a retractable power assist rod 202, and a power assist push rod 203;

[0038] The outer side of the bottom port of the sampling tube 1 is provided with a spiral cutting edge 101. The top of the sampling tube 1 is provided with a limiting ring 102. The top of the sampling tube 1 is inserted into the circular through hole 204 opened on the foot pedal 201. The limiting ring 102 is inserted into the insertion groove 205 at the bottom of the foot pedal 201 and is located below the circular through hole 204. The limiting ring 102 is fixed to the foot pedal 201 by bolts.

[0039] The spiral cutting edge 101 at the bottom of the sampling tube 1 can cut and break up the soil when it is inserted into the soil, making it easier for the sampling tube 1 to penetrate into the soil layer and improving sampling efficiency. For example, in harder soil, the spiral cutting edge 101 can easily chop up the soil and reduce insertion resistance.

[0040] The limiting ring 102 at the top of the sampling tube 1 is inserted into the insertion groove 205 at the bottom of the foot pedal 201 and is fixed to the foot pedal 201 by bolts. This connection method can ensure the stability between the sampling tube 1 and the foot pedal 201, prevent the sampling tube 1 from shaking or shifting during the sampling process, and ensure the accuracy of the sampling.

[0041] If sampling tube 1 is damaged or needs to be replaced with a different specification of sampling tube 1, simply loosen the bolts to remove sampling tube 1 from foot pedal 201, which is convenient and quick.

[0042] The assist push rod 203 passes through the insertion hole 103 at the top of the sampling tube 1 and is fixedly connected to the push plate 211. A telescopic assist rod 202 is fixed to the top of the foot pedal 201, and a guide plate 206 is fixedly provided on the outer sleeve of the telescopic assist rod 202. The guide plate 206 has a guide hole 207. The assist push rod 203 passes through the guide hole 207, and an auxiliary pedal 208 is fixedly provided at the top of the assist push rod 203. A limiting ring 209 is provided on the outer side of the assist push rod 203, above the guide plate 206, to limit the downward travel of the assist push rod 203 when it pushes the push plate 211 downward. The limiting ring 209 is positioned above the guide plate 206. An anti-slip handle 210 is provided at the top of the telescopic assist rod 202.

[0043] The push rod 203 passes through the sampling tube 1 and is fixedly connected to the push plate 211. The telescopic push rod 202 is fixed to the top of the foot pedal 201. By stepping down the auxiliary pedal 208, the push plate 211 can be moved down more easily with the help of the lever principle and the telescopic function of the push rod, so as to push out the soil sample in the sampling tube 1 and reduce the labor intensity of the operator.

[0044] The guide plate 206 and guide hole 207 on the outer tube of the retractable assist rod 202 provide guidance for the assist push rod 203, ensuring that the assist push rod 203 remains vertical during its up-and-down movement and avoiding deviation, thus ensuring that the push plate 211 can accurately eject the soil sample. The limiting ring 209 limits the downward stroke of the assist push rod 203, preventing the push plate 211 from moving too far downward and damaging the sampling tube 1 or the sample storage cylinder 302.

[0045] The top of the telescopic assist rod 202 is equipped with a non-slip handle 210, which allows the operator to grip the non-slip handle 210, increasing hand friction and comfort during operation. The length of the assist rod can also be adjusted as needed to accommodate operators of different heights and different operating scenarios.

[0046] The storage box 3 is provided with several annular slots 301 for inserting and placing sample storage tubes 302. The annular slots 301 at the front end of the storage box 3 are vertically aligned with the sampling tube 1. After the storage box 3 is connected to the foot pedal 201, the sampling tube 1 is inserted into the sample storage tube 302 in the annular slot 301 at the front end of the storage box 3.

[0047] The storage box 3 has several annular slots 301, into which multiple sample storage tubes 302 can be inserted, facilitating the classification and storage of different soil samples and preventing sample mixing. For example, when sampling at different locations or depths, different samples can be stored in different sample storage tubes 302.

[0048] The annular slot 301 at the front end of the storage box 3 is vertically aligned with the sampling tube 1. After the storage box 3 is connected to the foot pedal 201, the sampling tube 1 can be accurately inserted into the sample storage cylinder 302, ensuring that the soil sample can be smoothly transferred from the sampling tube 1 to the sample storage cylinder 302, reducing sample loss.

[0049] During operation, remove the assist frame 2 and sampling tube 1 from the storage box 3, place the sampling tube 1 on the surface of the soil to be sampled, step on the foot pedal 201, the sampling tube 1 extends into the soil layer, the soil pushes the push plate 211 and the assist push rod 203 upward, the soil is sampled into the sampling tube 1, pull out the assist frame 2 and sampling tube 1, connect the foot pedal 201 to the top of the storage box 3, step on the auxiliary pedal 208 to move the assist push rod 203 and push plate 211 downward, push the soil sampled in the sampling tube 1 into the sample storage cylinder 302 for storage. When taking different soil samples, place the different sample storage cylinders 302 into the annular slot 301 at the front end of the foot pedal 201 to facilitate taking different soil samples and storing the soil samples.

[0050] The entire sampling process only requires taking the assist frame 2 and sampling tube 1 out of the storage box 3 and placing them on the surface of the soil to be sampled. The sampling and sample transfer operations can be completed by stepping on the foot pedal 201 and the auxiliary pedal 208. No complicated tools and steps are required, which reduces the technical requirements of the operators.

[0051] The sample storage container 302 can be replaced at any time as needed, facilitating the collection of different soil samples and improving sampling efficiency and flexibility. For example, during large-scale soil surveys, samples can be quickly collected and stored at different locations.

[0052] By directly placing the soil sample into the sample storage container 302 for preservation, the contact time between the sample and the external environment is reduced, which helps to maintain the original state of the sample and provide accurate data for subsequent analysis and research.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
