Description

Technical Field

[0001] The utility model relates to the field of soil sample extraction devices, in particular to a soil sample extraction device for soil pollution detection. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. Many countries in the world, especially developed countries, have formulated and implemented contaminated soil management and remediation plans. Therefore, an emerging soil remediation industry has been formed. In the process of soil remediation, it is necessary to first sample and test the contaminated soil.

[0003] At present, when sampling soil, most of the time, ordinary manual samplers are used for sampling. After the workers manually insert the sampling tube into the ground to sample the soil, the workers take out the soil inside the sampling tube through a thimble or vibration to complete the sampling.

[0004] During the use of this soil sampling extraction device, when taking the sampling device out from the ground, workers are required to use a thimble or knock on the sampling tube to take out the soil in the sampling device. The sampling soil is likely to leak out during the taking out process, resulting in insufficient sampling quantity. In addition, each time sampling is taken, workers are required to manually take out the soil inside the sampling tube, which is relatively cumbersome and affects the sampling efficiency. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a soil sample extraction device for soil pollution detection to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil pollution detection soil sample extraction device, comprising a base plate and a sampling tube, a storage box is movably installed at one end of the base plate, and a support frame is fixedly installed at one end of the base plate, a first connecting rod is fixedly installed inside the support frame, and an extrusion plate is movably installed at one end of the first connecting rod, an inclined plate is fixedly installed at the top of the storage box, a movable plate is fixedly installed at one end, and a ejector pin is fixedly installed at one end of the support frame, a first spring is sleeved on the outside of the first connecting rod, and the base plate and the extrusion plate are connected by the first spring, and a reset component for helping the storage box to reset is fixedly installed at one end of the base plate.

[0007] By adopting the above technical scheme, by providing components such as the first spring, the ejector pin, the inclined plate, the extrusion plate, the slider, and the second connecting rod, when using the utility model, the worker only needs to apply pressure to the movable plate to sample the soil, and at the same time the extrusion plate squeezes the inclined plate to prevent the storage box from affecting its movement. After the sampling is completed, the ejector pin will push out the soil inside the sampling tube and drop it into the storage box, and the sampling of the soil can be completed. Compared with the traditional sampling device, the utility model can automatically push out the soil inside the sampling tube when in use, eliminating the need for workers to manually take out the soil inside the sampling tube.

[0008] The utility model is further configured such that the reset assembly includes a fixed block, a second connecting rod, a second spring, a sliding groove, a sliding block and a through hole, a fixed block is fixedly installed at one end of the base plate, and a second connecting rod is movably installed inside the fixed block, and a limiting block is fixedly installed at one end of the second connecting rod.

[0009] By adopting the above technical solution, the bottom plate provides fixation for the fixed block, so that the fixed block provides support for the second connecting rod. At the same time, the movably installed second connecting rod allows the second connecting rod to move inside the fixed block, and the limit block can impose a limit on the second connecting rod to prevent the second connecting rod from detaching from the fixed block.

[0010] The utility model is further configured that a sliding block is fixedly mounted on one end of the storage box, and a sliding groove for the sliding block to slide is provided on the end surface of the storage box.

[0011] By adopting the above technical solution, the slider cooperates with the slide groove to control the moving direction of the storage box, ensuring that when the extrusion plate applies pressure to the inclined plate, the storage box moves along the slide groove.

[0012] The utility model is further configured that a second spring is sleeved on the outside of the second connecting rod, and the fixing block and the sliding block are connected via the second spring.

[0013] By adopting the above technical solution, the second spring can continuously apply elastic force to the storage box to ensure that after the squeezing plate releases the squeezing of the inclined plate, the second spring helps the storage box to reset and collect the sampled soil.

[0014] The utility model is further configured that one end of the bottom plate is provided with a through hole for the sampling tube to pass through, and one end of the storage box is fixedly mounted with a fixing frame.

[0015] By adopting the above technical solution, the through hole provides a moving space for the sampling tube to pass through the bottom plate, and the fixing frame can fix the bottom plate on the surface of the sampled soil to prevent the bottom plate from moving during the sampling process and affecting the sampling of the sampling tube.

[0016] The utility model is further configured such that the top end surfaces of the extrusion plate and the inclined plate are both configured in an arc shape, and the diameter of the sampling tube is greater than the diameter of the ejector pin.

[0017] By adopting the above technical solution, the top end surfaces of the extrusion plate and the inclined plate are set in an arc shape, so that when the extrusion plate contacts the inclined plate, it will squeeze the position of the inclined plate to move, ensuring its force direction. The inclined plate will not affect the movement of the extrusion plate. The diameter of the sampling tube is larger than the diameter of the ejector pin, so that the ejector pin can enter the interior of the sampling tube, push out the soil inside the sampling tube, and drop it into the storage box.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] The utility model is provided with components such as a first spring, a push pin, an inclined plate, an extrusion plate, a sliding block, and a second connecting rod, so that when using the utility model, a worker only needs to apply pressure to the movable plate to drive the sampling tube to move downward to sample the soil. At the same time, the extrusion plate squeezes the inclined plate to prevent the storage box from affecting its movement. After the sampling is completed, the first spring can help the sampling tube to reset, and when the sampling tube moves upward, the push pin will push out the soil inside the sampling tube and drop it into the storage box, so as to complete the sampling of the soil. Compared with the traditional sampling device, the utility model can automatically push out the soil inside the sampling tube when in use, eliminating the need for workers to manually take out the soil inside the sampling tube. At the same time, in cooperation with the storage box, the soil that has escaped from the sampling tube can be collected, thereby greatly improving the overall sampling efficiency and reducing the work intensity of workers.

DETAILED DESCRIPTION

[0025] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] The working principle of the utility model is as follows: when using the utility model, the worker places the bottom plate 1 on the end face of the land to be sampled, and then fixes the fixing frame 17 inside the soil to provide a certain fixation and limit to the bottom plate 1. The worker applies pressure to the movable plate 8 to move the sampling tube 9 downward. After it moves a certain distance, the squeezing plate 6 squeezes the inclined plate 7 to move the position of the storage box 2, and the through hole 16 leaks out to prevent the storage box 2 from affecting the movement of the sampling tube 9, so that the sampling tube 9 samples the soil through the through hole 16. After the sampling is completed, the worker converts the pressure on the movable plate 8 into a pulling force, and at the same time, the first spring 5 applies an elastic force to the squeezing plate 6 to help it reset. After the sampling tube 9 moves a certain distance, the ejector pin 10 pushes the soil inside the sampling tube 9 out. At the same time, when the sampling tube 9 is reset, the squeezing plate 6 releases the squeezing of the inclined plate 7, so that the second spring 13 applies an elastic force to the storage box 2 to reset it, so that the sampled soil enters the storage box 2, and the sampling of the soil is completed.
