Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a deep soil sampling device for environmental detection, which solves the problems raised in the above background technique.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A deep soil sampling device for environmental detection includes a machine body. A spring plate is slidably installed on the top of the machine body. A motor is arranged on the top of the spring plate. The output end of the motor is fixedly installed with a spiral blade. A ring column is fixedly installed at the bottom of the spring plate. Wheels are arranged at the bottom of the machine body. A positioning mechanism is arranged at the bottom of the machine body. Among them, the positioning mechanism includes a fixed plate, a stress plate, a vertical plate, a pressing plate, a rubber block and a short rod. The fixed plate is fixedly installed on the circumferential surface of the ring column. A chute is provided on the front surface of the machine body.

Among them, a cleaning mechanism for cleaning at the sampling and detection site and a follow-up mechanism for filling the dug hole site are provided at the bottom of the machine body. When the triangular block moves, it will drive the limit frame to move at the bottom of the machine body. When the limit frame moves, the limit on the elastic telescopic column will be released. When the limit on the elastic telescopic column is released, the position of the machine body will be horizontal.

[0007] According to the above technical solution, the positioning mechanism further includes a pressing block, a triangular block, a limit frame and an elastic telescopic column. The pressing block is fixedly installed at the bottom of the other end of the short rod. The limit frame is slidably installed at the bottom of the machine body. The triangular block is fixedly installed at the top of the limit frame. The elastic telescopic column is fixedly installed at the bottom of the machine body. When the triangular block moves, it will drive the limit frame to move at the bottom of the machine body. When the limit frame moves, the limit on the elastic telescopic column will be released.

[0008] According to the above technical solution, the pressing block contacts the triangular block, the rubber block contacts the wheel, and the fixed plate contacts the stress plate. When the pressing plate moves, it will drive the rubber block to move. When the rubber block moves, it will contact the wheel. When the rubber block contacts the wheel, the machine body will stop moving due to the frictional force.

[0009] According to the above technical solution, the cleaning mechanism includes a bottom block, a convex plate, a long rod, a scraper, a square block and a telescopic rod. The bottom block is fixedly installed at the bottom of the stress plate. The convex plate is fixedly installed on the surface of the bottom block away from the ring column. The fixed end of the telescopic rod is fixedly installed at the bottom of the machine body. One end of the long rod is rotatably installed at the free end of the telescopic rod. A spiral groove is provided on the circumferential surface of the long rod near the telescopic rod. The scraper is fixedly installed on the circumferential surface of the other end of the long rod. The square block is fixedly installed on the right side of the machine body. A placement groove is provided at the bottom of the square block. When the rotating plate rotates, it will drive the clamping plate to move. When the clamping plate moves, the limit on the elastic telescopic plate inside the square block will be released. When the limit on the elastic telescopic plate is released, the weeds and sundries on the scraper will be cleaned and removed.

[0010] According to the above technical solution, the cleaning mechanism further includes a rotating plate, an elastic telescopic plate and a clamping plate. The elastic telescopic plate is fixedly installed inside the placement groove. The rotating plate is rotatably installed on the side of the square block away from the annular column. The clamping plate is fixedly installed on the side of the rotating plate close to the annular column. When the rotating plate rotates, it will drive the clamping plate to move. When the clamping plate moves, the limit on the elastic telescopic plate inside the square block will be released.

[0011] According to the above technical solution, the rotating plate is a flexible plate. A brush is provided on the elastic telescopic plate. The convex plate contacts the spiral groove on the long rod. When the bottom block moves, it will drive the convex plate to move in the spiral groove of the long rod. When the convex plate moves, the long rod below the telescopic rod will rotate.

[0012] According to the above technical solution, the follow-up mechanism includes a soft column, a door panel, a soil box, a clamping plate, a fixed column, a rounded corner column, a soft head plate, a round block and a round convex column. The clamping plate is fixedly installed on the left side of the machine body. The soil box is fixedly installed at the bottom of the clamping plate. A discharge port is opened at the bottom of the soil box. The door panel is slidably installed at the discharge port. The soft column is fixedly installed at the bottom of the door panel. The fixed column is fixedly installed inside the soil box. The rounded corner column is slidably installed inside the fixed column. The soft head plate is fixedly installed on the inner wall of the soil box. The round block is fixedly installed on the top of the door panel. The round convex column is fixedly installed on the side of the rounded corner column close to the soft head plate. When the soft column moves, it will drive the door panel at the discharge port of the soil box at the bottom of the clamping plate to move. When the door panel moves, the soil inside the soil box will fill the hole punched in the previous step. When the door panel moves, it will drive the round block to move.

[0013] According to the above technical solution, the round convex column contacts the soft head plate, the rounded corner column contacts the round block, and the soft column contacts the scraping plate. When the round convex column moves, it will contact the soft head plate. When the round convex column contacts the soft head plate, vibration will be generated.

[0014] The present invention provides a deep soil sampling device for environmental detection. It has the following beneficial effects: (1) In this invention, when the rubber block moves, it will contact the wheel. After the rubber block contacts the wheel, the machine body will stop moving through friction, and the soil sampling device can be accurately positioned at the target position to ensure that the location of each soil sampling meets the pre-set requirements. When the limit frame moves, the limit on the elastic telescopic column will be released. When the limit on the elastic telescopic column is released, the position of the machine body will be horizontal, enabling the internal mechanical transmission components to be evenly stressed, avoiding affecting the normal operation of the equipment, and preventing the internal optical path of the sensor from changing due to the tilt of the machine, thus increasing the reaction of the true humidity of the soil.

[0015] (2)When the limit of the elastic telescopic plate is released, the weeds and sundries on the scraper will be cleaned and removed, avoiding the influence of the residues from the previous cleaning on the subsequent cleaning. When the long rod rotates, it will drive the scraper to rotate. When the scraper rotates, it will clean the surface of the position where soil detection is to be carried out, ensuring that the soil samples taken are mainly the soil itself, improving the purity of the samples, and thus more accurately reflecting the true nature of the soil, and avoiding the entry of foreign objects from damaging the instrument or affecting its detection accuracy.

[0016] (3)When the round convex column moves, it will contact the soft head plate. When the round convex column contacts the soft head plate, vibration will be generated to avoid the blockage of soil at the discharge port. When the soft column moves, it will drive the door plate at the discharge port of the soil box at the bottom of the clamping plate to move. When the door plate moves, the soil inside the soil box will fill the holes punched in the previous step, which can make the soil surface return to flat, reduce the erosion of water flow on the soil, and at the same time, it can avoid people accidentally stepping into these holes and falling and getting injured in the outdoor environment, and also reduce the short-term and long-term adverse effects on the soil ecosystem caused by environmental changes.
