[0002] Constant temperature oscillators include constant temperature air bath oscillators that use air to maintain a constant temperature and constant temperature water bath oscillators that use water to maintain a constant temperature. Among them, the constant temperature water bath oscillator is also called a constant temperature water bath shaker. Its usage method is generally to fix the container on the oscillating bed, and then start the oscillation device to oscillate the container and the reagent in the container, thereby ensuring that the temperature of the reagent in the container is kept uniform, thereby improving the accuracy of the test.

[0003] At present, most of the soils in my country with excessive pollutants are still in a state of slight or mild pollution. Moderate and severe pollution points are usually distributed in the soil around polluting enterprises, while polluted cultivated land soils are basically in a state of slight or mild pollution. my country has a large population and a small amount of land, and the demand for agricultural products is under great pressure. The land production task is heavy, and slightly or slightly polluted cultivated land still needs to continue to engage in high-intensity agricultural production. Under this realistic national condition, it has become an urgent task to find ways to block or control the migration of heavy metals into the food chain, produce quality and safe agricultural products in slightly and slightly polluted farmland, and achieve a balance between the output and safety of agricultural production. Foliar barrier agents can block the absorption of crops and their transport to the aboveground parts from the plant link. In order to improve the quality of foliar barrier agents, it is usually necessary to test the foliar barrier agents. During the test process, first add the sample to the reagent and mix it evenly. Then, the foliar barrier agent in the sample is tested and analyzed by the instrument to obtain the result. According to the test results, the content of the foliar barrier agent in the sample can be judged. In order to improve the detection efficiency, a constant temperature oscillation device is usually required.

[0035] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3The tops of several test tube bodies 11 all penetrate the mounting plate 5, and a through hole 4 is opened on the surface of the mounting plate 5. A clamping assembly 3 is arranged between the several test tube bodies 11 and the mounting plate 5. The clamping assembly 3 includes a fixing plate 303, which is installed at the front and rear ends of the top of the mounting plate 5. A screw 302 is screwed inside the fixing plate 303. A turntable 301 is fixedly installed at one end of the screw 302 away from the test tube body 11. The end of the screw 302 close to the test tube body 11 is rotatably connected to a clamping seat 305 through a bearing, and a guide rod 304 is connected between the clamping seat 305 and the fixing plate 303. The staff rotates the turntable 301, and the rotation of the turntable 301 drives the screw 302 to rotate. Under the limiting action of the guide rod 304, the screw 302 rotates to drive the clamping seat 305 to move toward the test tube body 11 until the clamping seat 305 clamps and fixes the test tube body 11, trying to avoid collision and damage between the test tube body 11 and the fixing sleeve 7 during the oscillation process.

[0036] Please refer to the attached figure in the instruction manual Figure 3 The end of the clamping seat 305 close to the test tube body 11 is provided with an arc groove 3051, and the inner wall of the arc groove 3051 is connected with a rubber pad. The arc groove 3051 makes the clamping seat 305 and the test tube body 11 fit better, and the rubber pad increases the friction between the clamping seat 305 and the test tube body 11, so that the test tube body 11 is clamped more firmly.

[0037] Working principle: When in use, the test tube body 11 storing the leaf surface inhibitor is inserted into the interior of the fixed sleeve 7 in turn, and then the staff manually rotates the turntable 301, and the rotation of the turntable 301 drives the screw 302 to rotate. Under the limiting action of the guide rod 304, the screw 302 rotates to drive the clamping seat 305 to move toward the test tube body 11 until the clamping seat 305 clamps and fixes the test tube body 11.

[0038] Then the staff holds the pull rod 102 and pulls it outward. The pull rod 102 drives the movable plate 105 to move, and the movable plate 105 drives the T-bar 104 to move and stretch the positioning spring 103.

Under the elastic force of the positioning spring 103, the movable plate 105 is reset and drives the positioning block 107 to be inserted into the positioning groove 106, so that the cover 2 and the box body 6 are more tightly connected.

[0039] Then water is added to the water storage chamber 1004 through the water inlet pipe 1006, and the water is heated by the heating block 1003. The temperature sensor 1005 detects the water temperature in real time and transmits the data to the controller. When the temperature reaches the set value, the controller controls the heating block 1003 to stop heating, so that the inside of the water storage chamber 1004 is in a constant temperature state, which is convenient for the later detection of the leaf barrier agent inside the test tube body 11.

[0040] At the same time, the driving motor 903 is turned on, and the driving motor 903 drives the cam 902 to rotate when working. Since the cam 902 is eccentrically arranged relative to the output end of the driving motor 903, when the cam 902 rotates away from the eccentric end to fit the left side wall of the movable column 904, the reset spring 907 and the telescopic rod 908 contract. When the cam 902 rotates close to the eccentric end to fit the left side wall of the movable column 904, the movable column 904 moves to the left under the elastic force of the reset spring 907 and the extension of the telescopic rod 908, thereby realizing the reciprocating left and right movement of the movable column 904, and then being able to drive the supporting plate 8 and the box body 6 to move left and right, thereby oscillating the test tube body 11 in the box body 6.

[0041] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model.
