Description

Technical Field

[0001] The utility model belongs to the technical field of soil detection and sampling, and particularly relates to a soil nutrient detection and sampling device. Background Art

[0002] Soil nutrient testing is a vital agricultural analysis measure. It uses a series of scientific methods and technologies to carry out quantitative and qualitative determination of various nutrients contained in the soil. These nutrients include not only macroelements such as nitrogen, phosphorus, and potassium, but also trace elements such as calcium, magnesium, sulfur, iron, manganese, zinc, and copper. The testing process usually involves collecting representative soil samples, and then using chemical analysis methods such as spectrophotometry, titration, etc., or relying on advanced instruments and equipment, such as atomic absorption spectrometers, ion chromatographs, etc., to accurately Soil nutrient testing can accurately determine the content of various nutrients in the soil. Soil nutrient testing has far-reaching significance. It can help farmers clearly understand the fertility of the soil and then plan a reasonable fertilization plan. In this way, it can not only prevent the waste and environmental pollution caused by excessive use of fertilizers, but also ensure that crops obtain sufficient and balanced nutrient supply, improve the yield and quality of crops, and promote the development of agriculture in a sustainable direction. For example, once the test finds that the nitrogen content in the soil is deficient, the application of nitrogen fertilizer can be increased in a targeted manner to meet the growth needs of crops;

[0003] A Chinese patent with publication number "CN218512054U" discloses a device, which includes: two support rods, a hydraulic cylinder and a sampling mechanism for sampling deep soil. A mounting plate is provided on the side walls at the top of the two support rods, the hydraulic cylinder is mounted on the bottom of the mounting plate, the sampling mechanism is slidably connected between the two support rods, and the bottom of the hydraulic cylinder is connected to the sampling mechanism. The hydraulic cylinder and the sampling mechanism are limited by the support rods. When the sampling mechanism drives the spiral rod to rotate under the drive of the motor, the hydraulic cylinder pushes the sampling mechanism to move downward. By adjusting the distance that the hydraulic cylinder drives the sampling mechanism to move downward according to the demand, it is possible to sample soil at different depths, so that the data obtained during the detection is more accurate.

[0004] However, during the period of use, although the above-mentioned device can perform the function of drilling and sampling, the dust content generated during the drilling and sampling process is quite high. During use, it is very easy to cause dust to spread over a large area, thereby polluting the surrounding environment. At the same time, the dust itself will also cause harm to the human body. Therefore, it is necessary to improve the design thereof. Utility Model Content

[0029] Principle and advantages of use: By setting the drilling mechanism 6 to cooperate with the telescopic cylinder 4, the device can start the telescopic cylinder 4 to operate during the sampling process, and use the telescopic cylinder 4 to drive the bottom plate 5 to move downward. The bottom plate 5 can drive the drilling brick to move downward to contact the ground by moving downward. At this time, the driving motor 62 is started to operate, and the driving motor 62 drives the drilling drill bit 63 to rotate. The drilling drill bit 63 rotates and moves downward. At this time, the drilling drill bit 63 can be stably drilled into the soil. By adjusting the up and down movable displacement of the drilling drill bit 63, the soil at different depths can be flexibly drilled and sampled. In addition, the bridge-type handrail 9 can be lifted and pulled to assist in carrying the device flexibly during use, which can improve the convenience of the overall operation of the device for sampling.

[0030] By setting up the dust-proof mechanism 7, during the use of the device, during the drilling and sampling process, the suction fan 72 can be started to run, and the suction fan 72 can be used to generate negative pressure. At this time, the negative pressure can be used to suck air, and the suction cover cooperates with the suction bucket 743 to guide the dust, so that the dust can be transported and discharged to the inside of the filter box 731 through the hose 741, and the filter box 732 inside the filter box 731 assists in filtering the dust. During this period, the dust can be assisted by the filter cover 742 to block the dust, which can prevent the dust from spreading. The suction bucket 743 is set on the inner side of the filter cover 742. At this time, the filter cover 742 is used to block the air and collect the dust, which can reduce the impact of dust on the surrounding environment and improve the performance of the device. The purification effect of the overall dust collection can improve the overall ease of use of the device. If the filter box 732 needs to be removed for cleaning during use, the filter box 732 can be removed by simply moving the groove 735 and pulling the sealing plate 733 outward, so that the device can easily collect filtered dust. At the same time, during use, two sets of dust-proof mechanisms 7 are set to operate alternately. When the drilling position is shallow, the suction fan 72 can be started to operate for suction sampling. At this time, the sampling is at a shallow position. When the drilling position is deep, the suction fan 72 of another set of dust-proof mechanisms 7 can be started to operate. At this time, it can assist in absorbing dust at a deeper position, which is convenient for flexible adjustment of the sampling depth and shallowness of the samples, and can improve the overall ease of use of the device.
