Description

Technical Field

[0002] Soil environmental monitoring refers to determining the environmental quality and its changing trends by measuring the representative values ​​of factors that affect soil environmental quality. What we usually call soil monitoring refers to soil environmental monitoring, which generally includes technical contents such as point sampling, sample preparation, analysis methods, result characterization, data statistics and quality evaluation. After sampling the soil, soil samples need to be prepared. Since the soil samples may contain some stones, sticks, iron blocks and other debris, it will affect the preparation of soil samples and also affect the subsequent soil sample test results. Therefore, the soil samples collected need to be pretreated.

[0003] Existing soil detection devices generally require soil samples to be taken to a detection base for detection, so a portable soil sample detection device is needed, and the soil needs to be directly and automatically sampled during detection, and the soil sample is directly transmitted to the detection device during sampling. When transmitting to the detection device, the detected soil will be squeezed during transmission and formed into blocks, which makes it difficult for the soil to enter the sampling device for detection. At the same time, the blocky soil will block the transmission path, thereby damaging the device. Summary of the invention

[0014] The present invention has the following beneficial effects: (1) In the present invention, when the soil to be tested enters the interior of the processing box, the connection between the transmission rod and the partition plate drives the baffle to rotate inside the processing box, and the soil continuously transmitted upward to the interior of the processing box is pushed on the inner edge of the baffle by the extrusion force. Through the extrusion force and the rotation of the baffle, the crushing roller crushes the soil squeezed toward the edge, thereby realizing the pretreatment of the soil, and the soil inside the processing box is scraped by the rotation of the scraper blade and the arc shape of the scraper blade, so that the soil enters the top of the lifting plate through the outlet, thereby completing the pretreatment of the soil, avoiding the soil to be tested from being squeezed during transmission to the detection device and forming blocks, which makes it difficult for the soil to enter the sampling device for detection, and also avoiding the block of soil blocking the transmission path, thereby avoiding damage to the device due to blockage.

[0015] (2) After the soil sample is pre-treated and enters the top of the lifting plate, the lifting plate is pushed upward by the hydraulic cylinder, and the detector is pushed upward by the cooperation of the slide rod, the adapter plate and the connecting column so that the lifting plate reaches the top of the processing box. At the same time, during the rising process of the detector, the limit tube and the cover plate are pulled upward by the connecting frame so that the cover plate is aligned with the top of the baffle frame, so that the top of the processing box, the top of the lifting plate and the top of the cover plate form a plane, and the extension ring will correspond to the lifting plate. The cover plate prevents the soil from falling to the top of the partition inside the baffle frame as the lifting plate rises, thereby avoiding contamination of the inside of the baffle frame. At the same time, the rotation of the baffle frame drives the double arc scraper to rotate. The S shape of the double arc scraper frame can push the lifting plate and the soil on the top of the cover into the extension ring for detection by the detector, thereby increasing the practicality of the device.

[0016] (3) The present invention can replace the fixed inspection device through the device as a whole, so that the inspection personnel can carry the device to the field to conduct soil inspection by the handle, so that multiple soils or soils in multiple areas can be inspected in real time, thereby increasing practicality. When inspecting the soil, the bottom of the limit plate is placed at the place where the soil needs to be inspected by controlling the handle, and the spring and the telescopic hose are contracted by pressing the handle, so that the bottom of the spiral conveying paddle inside the main body contacts the surface of the soil. The spiral conveying paddle is rotated inside the main body by connecting the transmission device to the top of the transmission rod, so that the soil is transmitted upward through the texture and rotation inertia of the spiral conveying paddle, replacing the manual collection of soil samples, reducing manpower, and improving the efficiency of sample collection. In the process of transmitting the soil through the abutment plate, the blocky soil is pre-processed and decomposed by the crushing blade, which facilitates the transmission of the soil to the inside of the processing box.
