Description

Technical Field

[0001] The invention relates to the technical field of sampling, in particular to a sampling device for vertical detection of soil pollution capable of sampling in different areas. Background Art

[0002] Zoning sampling is a sampling method that divides the whole object (such as soil, water, materials, etc.) into different areas or layers according to specific rules, and then obtains samples independently from each area or layer. The purpose of this method is to more accurately understand the differences in characteristics of different parts of the object. The soil pollution vertical sampling device is a device specially used to obtain soil samples at different depths in the vertical direction. Its main purpose is to accurately collect soil samples to analyze the distribution of soil pollutants (such as heavy metals, organic matter, pesticides, etc.) in the vertical soil layer. When there are too many harmful substances in the soil, exceeding the self-purification capacity of the soil, it will cause changes in the composition, structure and function of the soil, inhibit microbial activity, and gradually accumulate harmful substances or their decomposition products in the soil. Through "soil → plant → human body" or "soil → water → human body", it is indirectly absorbed by the human body to the extent that it endangers human health. This is soil pollution.

[0003] In the prior art, the detection of vertical soil pollution level is to fix the detection device in a specific place, so that the soil pollution level can only be detected in a specific area. However, the pollution levels in different areas of the same place may be different. Therefore, it is impossible to obtain relatively accurate data by detecting the soil pollution level in only one place. In addition, the components are severely adhered during the sampling process, which can easily affect the service life of the components. Therefore, a new design was made to address this situation. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A sampling device for vertical detection of soil pollution capable of sampling in different zones, comprising: A composite mechanism for sampling soil for testing; A processing mechanism, the processing mechanism is used to clean the composite mechanism; A frame, which is used to support the composite mechanism and the processing mechanism; The outer side of the composite mechanism is fixedly connected to the top of the frame, and the top of the processing mechanism is fixedly connected to the bottom of the frame; The composite mechanism comprises a composite body, the inner side of which is fixedly connected with a telescopic rod, and the composite body is controlled to be raised and lowered by the telescopic rod to meet the working requirements; the outer side of the telescopic rod away from the composite body is fixedly connected with the top of the frame; the outer side of the composite body is fixedly connected with a motor, and the docking tube is fixed by a clamping mechanism, so as to facilitate the replacement of the internal components of the sampling mechanism, and avoid serious wear of the components after long-term operation, thereby affecting the sampling effect of the components; the outer side of the motor close to the processing mechanism is fixedly connected with a clamping mechanism, and the docking tube is squeezed by the clamping mechanism to achieve the function of fixing the components; the clamping mechanism The inner side of the mechanism is clamped and connected with a docking tube, and the clamping mechanism is driven to rotate by a motor, which is convenient for subsequently driving the sampling mechanism to rotate, so as to achieve soil sampling. The inner side of the docking tube is fixedly connected with the sampling mechanism. By increasing the sampling mechanism to increase the storage range, it is convenient to perform multi-level sampling and storage inside the soil, so as to facilitate subsequent detection. The outside of the sampling mechanism is fixedly connected with a drill bit mechanism on the side away from the motor. A drill bit mechanism is arranged at the bottom of the sampling mechanism. The drill bit mechanism is rotated to achieve the soil breaking effect and increase the soil breaking speed. At the same time, hard stones are broken in the process of drilling to avoid affecting the sampling effect. As the drilling area goes deeper.

[0005] Preferably, the clamping mechanism includes a clamping shell, a first electric push rod is fixedly connected to one side of the outside of the clamping shell, and the first electric push rod is extended and retracted to make the clamping block drive the connecting rod to slide inside the clamping shell, so as to clamp the component, thereby fixing the component and facilitating maintaining a certain stability during subsequent operations to avoid affecting the drilling effect. A clamping block is fixedly connected between the opposite surfaces of the first electric push rod, and a connecting rod is fixedly connected to the inner side of the clamping block. Secondly, it is convenient to disassemble while achieving quick fixation, so as to replace components and avoid serious wear of components after long-term operation, thereby affecting the sampling effect. Therefore, the operation difficulty is reduced and the operation efficiency is improved. The outer side of the connecting rod is slidably connected to the outer side of the clamping shell.

[0006] Preferably, the sampling mechanism includes a sampling shell, a second electric push rod is fixedly connected to a side of the inner wall of the sampling shell close to the docking tube, soil accumulates inside the sampling tube, and there is a certain difficulty in the subsequent material collection process. The second electric push rod is used to control the circular block to squeeze the soil inside the sampling tube, so as to achieve the effect of squeezing out the soil, thereby reducing the difficulty of material collection and improving work efficiency. A circular block is fixedly connected to the side of the outside of the second electric push rod away from the docking tube, and a buffer mechanism is fixedly connected to the side of the outside of the circular block. The sampling tube is threadedly connected to the side of the outside of the sampling shell away from the docking tube. The sampling mechanism rotates with the rotation of the motor, so that the drill bit mechanism breaks the soil wall, thereby facilitating sampling of the sampling tube. The sampling tube adopts a long cylindrical structure, so that soil of different layers can be stored during sampling, so as to achieve the effect of enriching the sampling effect and facilitate subsequent detection. At the same time, the sampling tube is threadedly connected, so as to facilitate disassembly and can be replaced when it is severely worn in the later stage.

[0007] Preferably, the buffer mechanism includes a sliding rod, the outer side of the sliding rod is slidably connected to the outer side of the circular block, and a circular plate is fixedly connected to the side of the sliding rod away from the circular block. When the soil inside the sampling tube continues to accumulate, the soil squeezes the circular plate, causing the sliding rod to compress the spring bar, thereby achieving the effect of shock absorption and buffering, reducing the pressure on the components, avoiding component wear, and thus extending the service life of the components. A spring bar is sleeved on the side of the sliding rod close to the circular plate. When the soil is squeezed out, it rebounds through the elastic structure of the spring bar, thereby increasing the jitter amplitude of the component, thereby further reducing soil adhesion and keeping the inside of the equipment clean. An external block is fixedly connected to the side of the circular plate away from the sliding rod, and the second electric push rod pushes the circular plate, thereby achieving the effect of squeezing the soil out, and increasing the space gap with the soil through the external block, thereby reducing soil adhesion to the surface of the component, preventing blockage, and avoiding affecting subsequent operations.

[0008] Preferably, the drill mechanism includes a drill housing, one side of the inner wall of the drill housing is fixedly connected to the outer side of the sampling tube, and a sawtooth block is fixedly connected to the outer side of the drill housing away from the sampling tube. The sawtooth block increases the soil breaking effect, thereby increasing the drilling speed and improving the working efficiency. A funnel plate is fixedly connected to the inner wall of the drill housing close to the sawtooth block. The funnel plate plays a role in guiding the entry of materials, thereby accelerating the soil entry speed. A grinding block is fixedly connected to the outer side of the funnel plate. There may be stones inside the soil. When the components are driven to rotate by the motor, the stones are ground by the grinding block, thereby achieving the effect of crushing the stones, avoiding the stones from blocking the components, and preventing larger stones from entering the components and causing blockage inside the components, thereby preventing the subsequent working efficiency from being affected, thereby maintaining the normal operation of the equipment.

[0009] Preferably, an annular frame is fixedly connected to the side of the funnel plate away from the sawtooth block, and the pipe opening is narrowed on the side of the funnel plate close to the annular frame to increase the soil entry speed. A spring rod is fixedly connected to the outer side of the annular frame, and the annular frame is supported by the spring rod to achieve shock absorption and buffering, improve the stability of the components, reduce the vibration amplitude of the components, and avoid affecting the operation of the components. The side of the spring rod away from the annular frame is fixedly connected to the inner wall of the drill bit housing.

[0010] Preferably, the processing mechanism includes a connecting bracket, one side of the outside of the connecting bracket is fixedly connected to the bottom of the frame, and the side of the outside of the connecting bracket away from the frame is fixedly connected to an annular shell. When the sampling mechanism is moved toward the ground by lifting and lowering the telescopic rod, it extends to the inside of the annular shell through the hollow top of the frame, and the sampling mechanism is wrapped by the annular shell to achieve the effect of anti-drift, avoiding the deviation of the components during operation, thereby affecting the sampling effect, affecting the sampling depth, and at the same time affecting the working environment and easily causing harm to the operators.

[0011] Preferably, a connecting bracket is fixedly connected to the inner side of the annular shell, and a friction column is rotatably connected between the opposite surfaces of the connecting bracket. When the sampling mechanism is driven to rotate by the motor, the outer side of the sampling mechanism rubs against the surface of the friction column, so as to clean the surface impurities, reduce the adhesion of mud to the surface of the component, and prevent the mud from adhering to the surface of the component for a long time and causing corrosion to the surface of the component, so as to extend the service life of the component. If the mud is not cleaned, it is easy to cause cross interference of samples, thereby affecting the sampling effect. A cylindrical groove is provided on the outer side of the friction column. By providing the cylindrical groove, the contact area is increased by providing the groove, so as to increase the cleaning effect. At the same time, the chip removal effect is enhanced by grooving, and the mud is reduced from adhering to the surface of the component to prevent affecting the subsequent friction cleaning effect.

[0012] Preferably, the processing mechanism also includes an elastic rod, one side of the outside of the elastic rod is fixedly connected to the side of the annular shell close to the friction column, and the support plate is supported by the elastic rod to achieve the effect of shock absorption and buffering, reduce the friction vibration amplitude of the components, improve the stability of the components during operation, and maintain the normal operation of the equipment. The side of the outside of the elastic rod away from the annular shell is fixedly connected to the support plate, and the side of the outside of the support plate away from the elastic rod is fixedly connected to the friction block. When the friction column and the sampling mechanism rotate in friction, the friction column rubs against the friction block, and the friction column is rubbed by the friction block, so as to achieve the effect of cleaning impurities in the components, reduce soil adhesion, and make the overall component have a certain self-cleaning effect.

[0013] The present invention provides a sampling device for vertical detection of soil pollution capable of sampling in different zones. It has the following beneficial effects: 1. The sampling device for vertical detection of soil pollution with partitioned sampling is designed with a composite mechanism. The butt joint is squeezed by the clamping mechanism to achieve the function of fixing the components. The clamping mechanism is driven to rotate by a motor, which is convenient for the subsequent rotation of the sampling mechanism to achieve soil sampling. The storage range is increased by increasing the sampling mechanism, which is convenient for multi-level sampling and storage inside the soil, so as to facilitate subsequent detection. A drill mechanism is provided at the bottom of the sampling mechanism. The drill mechanism is rotated to achieve the soil breaking effect and increase the soil breaking speed. At the same time, hard stones are broken in the process of drilling to avoid affecting the sampling effect. As the drilling area goes deeper, the composite body is controlled to rise and fall by the telescopic rod to meet the work needs. Secondly, the butt joint is fixed by the clamping mechanism to facilitate the replacement of internal components of the sampling mechanism to avoid serious wear of components after long-term operation, thereby affecting the sampling effect of the components.

[0014] 2. The sampling device for vertical detection of soil pollution with partitioned sampling is designed with a sampling mechanism. The sampling mechanism rotates with the rotation of the motor, so that the drill mechanism breaks the soil wall, which is convenient for sampling with a sampling tube. The sampling tube adopts a long cylindrical structure, so that soil of different layers can be stored during sampling, so as to achieve the effect of enriching the sampling effect and facilitate subsequent detection. At the same time, the sampling tube adopts a threaded connection, which is convenient for disassembly and can be replaced when it is severely worn in the later stage. The soil accumulates inside the sampling tube, which is difficult to obtain in the subsequent material collection process. The second electric push rod controls the circular block to squeeze the soil inside the sampling tube, so as to achieve the effect of squeezing out the soil, thereby reducing the difficulty of obtaining materials and improving work efficiency.

[0015] 3. The sampling device for vertical detection of soil pollution with partitioned sampling is designed with a buffer mechanism. When the soil inside the sampling tube is continuously accumulated, the soil squeezes the circular plate, causing the sliding rod to compress the spring bar, thereby achieving the effect of shock absorption and buffering, reducing the pressure on the components, avoiding component wear, and thus extending the service life of the components. The second electric push rod pushes the circular plate to achieve the effect of squeezing the soil out, and the space gap with the soil is increased by the external block to reduce the soil adhesion on the surface of the component, prevent blockage, and avoid affecting subsequent operations. When the soil is squeezed out, it rebounds through the elastic structure of the spring bar, thereby increasing the vibration amplitude of the component, thereby further reducing soil adhesion and keeping the inside of the equipment clean.

[0016] 4. The sampling device for vertical detection of soil pollution with partitioned sampling is designed with a drill mechanism and a sawtooth block to increase the soil breaking effect, thereby increasing the drilling speed and improving the operation efficiency. The funnel plate guides the material to enter, thereby accelerating the soil entry speed. There may be stones inside the soil. When the motor drives the components to rotate, the grinding block grinds the stones to achieve the effect of crushing the stones, avoiding the stones from blocking the components and preventing larger stones from entering the components to block the components, thereby preventing the subsequent operation efficiency from being affected, thereby maintaining the normal operation of the equipment. The funnel plate is close to the side of the annular frame to reduce the pipe mouth, thereby increasing the soil entry speed. The annular frame is supported by a spring rod, thereby achieving the effect of shock absorption and buffering, improving the stability of the components, reducing the vibration amplitude of the components, and avoiding affecting the operation of the components.

[0017] 5. The sampling device for vertical detection of soil pollution with partitioned sampling is designed with a processing mechanism. When the sampling mechanism is moved to the ground by lifting the telescopic rod, it extends to the inner side of the annular shell through the hollow part at the top of the frame, and the sampling mechanism is wrapped by the annular shell to achieve the effect of anti-drift, avoid the deviation of the component during operation, thereby affecting the sampling effect and the sampling depth, and at the same time affecting the working environment and causing harm to the operators. When the sampling mechanism is driven to rotate by the motor, the outer side of the sampling mechanism is rubbed with the surface of the friction column, so as to achieve the effect of cleaning surface impurities, reduce the adhesion of soil to the surface of the component, and prevent the soil from adhering to the surface of the component for a long time and causing corrosion to the surface of the component, so as to extend the service life of the component. If the soil is not cleaned, it is easy to cause cross interference of samples, thereby affecting the sampling effect. By opening the cylindrical groove, the contact area is increased by opening the groove, so as to increase the cleaning effect. At the same time, the chip removal effect is enhanced by grooving, and the soil is reduced from adhering to the surface of the component to prevent affecting the subsequent friction cleaning effect.
