Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a sampler for land engineering survey. Background Art

[0002] A soil sampler is a tool used to obtain soil samples. Commonly used tools include soil augers, spades, and shovels. A soil augers consist of a drill bit and a handle made of hard material (steel or hard plastic). The drill bit is often spiral or cylindrical. Soil samplers truly meet the requirements of sampling the entire soil layer, the same amount, and conveniently. They solve the difficult problem of accurately collecting soil samples for soil testing, fertilization formulation, soil monitoring, and other soil and fertilizer applications.

[0003] According to the "A Land Monitoring Sampling Device" disclosed in Chinese Patent Publication No. CN220270835 U, the device includes an excavation barrel, a transmission rod is installed at the upper end of the excavation barrel, a telescopic handle is installed at the top of the transmission rod, and a soil cutting assembly is detachably installed at the end of the excavation barrel away from the transmission rod; the interior of the excavation barrel is slidably connected to an extrusion plate, and a driving rod is installed on the outside of the extrusion plate, and the driving rod passes through the excavation barrel to the interior of the transmission rod, and a slide groove is provided on the outside of the transmission rod, and a card groove connected to the slide groove is provided on the outside of the transmission rod, and a foot pedal is installed on the outside of the connecting block. When the sampled soil is discharged, the foot pedal is turned into the slide groove, or the foot pedal is stepped on by the foot. At this time, the foot pedal drives the driving rod downward through the connecting block, and the driving rod discharges the soil in the excavation barrel to the outside through the extrusion plate; in summary, the practicality of the device is increased by combining the foot pedal component with the soil discharge component.

[0004] When using the above-mentioned prior art, the foot pedal is pressed down by the foot to make the entire device move downward to sample the soil. However, when using this method, only one end is pressed down, and the force is unevenly applied. This can easily cause the sampling tube to enter the soil with one end deep and the other end shallow. As a result, the extracted soil sample is not representative in terms of layer and composition, affecting the accuracy of the analysis. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide a sampler for land engineering survey, which can achieve uniform force on both sides, avoid uneven depths on both sides of the sampling tube, and improve the sampling quality.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A sampler for land engineering surveying comprises a sampling cylinder, a sampling mechanism is provided on the outside of the sampling cylinder, and a storage mechanism is provided on the top of the sampling cylinder;

[0008] The sampling mechanism includes a connecting block and a connecting sleeve. One end of the connecting block is hinged with a pressure plate, the bottom of the pressure plate is fixedly connected to a fixed cone, a spiral groove is opened on the outside of the connecting sleeve, and one end of the connecting block is provided with a connecting assembly;

[0009] The storage mechanism comprises a storage shell, a storage tube is hingedly connected inside the storage shell, and an adjusting rod is slidably connected inside the storage tube.

[0010] Preferably, the connecting assembly includes a connecting ring, and a positioning rod is fixedly connected to the inner side of the connecting ring.

[0011] Preferably, one end of the connecting ring is fixedly connected to one end of the connecting block, and one end of the positioning rod is movably connected to the inner side of the spiral groove.

[0012] Preferably, the connecting sleeve is fixedly connected to the top of the sampling cylinder, and two connecting blocks are provided, and the two connecting blocks are arranged to be symmetrically distributed on the left and right.

[0013] Preferably, cutting teeth are fixedly connected to the bottom of the sampling cylinder, and an anti-slip pad is provided on the top of the pressing plate.

[0014] Preferably, the storage shell is fixedly connected to the top of the sampling cylinder, and the top of the adjustment rod is fixedly connected to a telescopic handle.

[0015] Preferably, the outside of the adjusting rod and the receiving tube are both provided with a fixing groove, and the inner side of the fixing groove is clamped with a fixing block.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] First, connect it to the sampling tube through the connecting sleeve, and then connect the positioning rod to the spiral groove, so that the connecting ring and the connecting block are in contact with the ground, thereby preliminarily fixing the positioning rod, and then rotate the pressure plate so that the bottom of the pressure plate is also in contact with the ground, and the fixed cone at the bottom of the device is inserted into the ground, thereby fixing the pressure plate to avoid shaking during sampling, and then the staff steps on the pressure plate with their feet, and uses the anti-slip pad on the top to avoid slipping and improve safety. Then the staff rotates the sampling tube through the telescopic handle, and it is movably connected to the positioning rod through the set spiral groove. Due to the fixation of the connecting block, the positioning rod is in a fixed state, so that the sampling tube can be rotated downward, and the cutting teeth at the bottom of the sampling tube allow the sampling tube to be easily rotated into the interior of the soil for sampling, completing the sampling operation, achieving uniform force on both sides, avoiding uneven depths on both sides of the sampling tube, and improving the sampling quality.

[0018] Second, by pulling the telescopic handle on the top of the adjusting rod, the adjusting rod slides upward until the fixed groove on the outside of the adjusting rod corresponds to the fixed groove on the outside of the storage tube, and then the fixing block is inserted into the fixing groove to engage with the fixing groove, thereby fixing the adjusting rod and the storage tube to complete the length adjustment. Then the staff can use the telescopic handle to rotate the sampling tube to take soil samples. After the work is completed, the fixing block is removed to make the adjusting rod slide into the storage tube to reduce the volume of the rod. Then, the storage tube is rotated to make the storage tube retracted into the storage shell, thereby reducing the volume of the sampling device as a whole, making it easier to carry the sampling device and achieving the effect of easy carrying.
