[0022] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: an adjustable water bath extraction device for determining effective boron in soil, comprising a water bath 1, a supporting leg 2 fixedly connected to the bottom of the water bath 1, a base 3 fixedly connected to the bottom end of the supporting leg 2, a positioning groove 4 provided on the base 3, a fixing plate 5 slidably connected in the positioning groove 4, a motor 6 fixedly connected to the middle of the top surface of the fixing plate 5, a threaded rod 7 fixedly connected to the output end of the motor 6, the threaded rod 7 is threadedly connected to the middle of the bottom surface of the water bath 1, a movable plate 9 is rotatably connected to the top of the threaded rod 7, a connecting column 13 is fixedly connected to the top surface of the movable plate 9, a bottom plate 14 is fixedly connected to the bottom of the connecting column 13, a supporting plate 15 is fixedly connected to the top of the connecting column 13, a positioning hole 16 is provided on the supporting plate 15, and an extraction tube 17 is inserted in the positioning hole 16.

[0024] The movable plate 9 is provided with evenly distributed water-permeable holes 10, so that when the movable plate 9 is adjusted in the water bath 1, the heating liquid can effectively heat the leaching tube 17 plugged in the positioning hole 16. A slide groove 12 is provided on the inner wall of the water bath 1, and a slider 11 is provided on the outer side of the movable plate 9. The slider 11 is slidably connected in the slide groove 12, which effectively limits the position of the movable plate 9, making the movable plate 9 more stable in the water bath 1, and preventing the movable plate 9 from deviating as the threaded rod 7 rotates. Two groups of support plates 15 are arranged in parallel, which effectively fix the leaching tube 17 plugged in the positioning hole 16 on the support plate 15, and increase the stability during the experiment. The top surfaces of the fixed plates 5 on both sides of the motor 6 are fixedly connected to the limiting columns 8, and the limiting columns 8 are fixedly connected to the bottom surface of the movable plate 9 away from one end of the fixed plate 5. The limiting columns 8 are slidably connected to the bottom of the water bath 1, and the fixed plate 5 is limited to prevent the motor 6 from driving the fixed plate 5 to rotate during operation, thereby enhancing the stability of the structure during the experiment.

[0025] Working principle: When conducting an extraction experiment on soil, inject the heating liquid into the water bath 1, electrically connect the water bath 1 to an external power supply, add the soil extract and soil into the extraction tube 17, insert the extraction tube 17 into the positioning hole 16 on the support plate 15, start the water bath 1, and the heating liquid flows through the water permeable hole 10 to the outer wall of the extraction tube 17 to heat the extraction tube 17. When the heating position of the extraction tube 17 needs to be changed, start the motor 6, the motor 6 drives the threaded rod 7 to rotate, the threaded rod 7 moves at the bottom of the water bath 1 through the thread, and the top of the threaded rod 7 rotates and is connected to the movable plate 9. The bottom, thereby the threaded rod 7 mobilizes the movable plate 9 to effectively lift up. When the movable plate 9 is lifted, the bottom plate 14 and the support plate 15 on the connecting column 13 fixedly connected to the top surface of the movable plate 9 are driven to rise, so that the position of the leaching tube 17 is lifted in the water bath pot 1. Since the position of the heating liquid flows through the water-permeable holes 10 on the movable plate 9 and remains unchanged, the heating position of the leaching tube 17 is lowered, effectively reducing the heating effect. When it is necessary to improve the heating effect of the leaching tube 17, the motor 6 is run in reverse to drive the movable plate 9 to descend, thereby driving the leaching tube 17 to be effectively heated in the heating liquid.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
