Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil detection, in particular to a multi - soil high - efficiency detection device. Background Technique
[0002] With the continuous acceleration of the industrialization process, due to the unreasonable exploitation of mineral resources and their smelting emissions, long - term sewage irrigation and sludge application to the soil, atmospheric deposition caused by human activities, the application of chemical fertilizers and pesticides, etc., the soil pollution is serious. Although the soil itself has a certain purification ability, when the amount of pesticides entering the soil exceeds the environmental capacity of the soil, soil pollution will be formed, which has a serious impact on the soil ecosystem. At the same time, it will enter the human body through the food chain and endanger human health. In order to repair the soil, it is necessary to flexibly select the repair method according to the soil environment, which requires sampling and detecting the soil.
[0003] Most of the existing detections are carried out by adding an analytical solution to the sampled soil. The sampled soil is put into a test tube, and the analytical solution is added to the test tube through a dropper or a syringe. After the analytical solution and the soil sample come into contact and mix, the detection is carried out. However, when multiple sampled soils need to be detected, the detector needs to continuously inject the analytical solution into the test tubes of each sampled soil, resulting in a greatly extended detection time and an increased labor intensity of the detector. Content of the Utility Model
[0004] The utility model aims to solve the above problems, and thus provides a multi - soil high - efficiency detection device that reduces the detection time of sampled soil.
[0005] The technical solution adopted by the utility model to solve the above problems is as follows:
[0006] A multi - soil high - efficiency detection device includes a base. In the middle of the top surface of the base, there is a test - tube rack. On both sides of the top of the base, support rods are longitudinally arranged. Between the middle parts of the support rods, there is a fixing frame. The fixing frame is provided with positioning holes corresponding to the number of holes in the test - tube rack. Syringes are placed in the positioning holes. Above the fixing frame and between the support rods, there is a downward - pressing mechanism.
[0007] The utility model adopting the above - mentioned technical solution, compared with the prior art, has the prominent feature that:
[0008] Put the test tubes containing multiple sampled soils into the test - tube rack respectively, add the analytical solution to multiple syringes, and place them in the positioning holes so that the syringes are opposite to the test tubes. Control the downward - pressing mechanism to descend, and at the same time squeeze the piston handle of the syringe, so that the analytical solution in the syringe is injected into the lower test tube. When detecting multiple sampled soils simultaneously, the detection time is greatly reduced, and the labor intensity of the detector is reduced.
[0009] Preferably, a further technical solution of the present utility model is as follows:
[0010] Further, the diameter of the positioning hole is larger than the diameter of the barrel of the syringe barrel and smaller than the diameter of the annular support plate on the syringe barrel.
[0011] Further, the pressing mechanism includes a movable plate opposite to the fixed frame. Sleeves slidably sleeved on the support rods are respectively fixedly provided on both sides of the movable plate. Positioning rods are respectively horizontally provided on the sides of the sleeves away from the movable plate. A rotating shaft movably penetrates through the back side of the base along the length direction. Connecting rods are respectively provided at both ends of the rotating shaft. An operating rod is provided between the outer ends of the connecting rods. A linkage rod is hinged between the middle of the positioning rod and the connecting rod.
[0012] Further, a limiting rod is provided between the tops of the support rods.
[0013] Further, a hook is hinged to one end of the limiting rod, and the hook is hooked on the adjacent positioning rod. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 is a schematic three-dimensional structure diagram of an embodiment of the present utility model;
[0015] The marks in the figure are: base 1, test tube rack 2, support rod 3, fixed frame 4, positioning hole 5, movable plate 6, sleeve 7, positioning rod 8, connecting rod 9, operating rod 10, linkage rod 11, limiting rod 12, hook 13. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The present utility model will be further described below in conjunction with embodiments. The purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.
[0017] A multi-sample soil high-efficiency detection device includes a base 1. A test tube rack 2 is provided in the middle of the top surface of the base 1. Support rods 3 are longitudinally provided on both sides of the top of the base 1. A fixed frame 4 is provided between the middle parts of the support rods 3. Positioning holes 5 corresponding to the number of holes of the test tube rack 2 are opened on the fixed frame 4. Syringes are placed in the positioning holes 5. A pressing mechanism is provided between the support rods 3 and above the fixed frame 4.
[0018] Further, the diameter of the positioning hole 5 is larger than the diameter of the barrel of the syringe barrel and smaller than the diameter of the annular support plate on the syringe barrel. The annular support plate is the convex part on the side of the syringe barrel away from the syringe nipple. The syringe barrel is stuck in the positioning hole 5, and the annular support plate on the syringe barrel limits the syringe.
[0019] Furthermore, the pressing mechanism includes a movable plate 6 opposite to the fixed frame 4, and sleeves 7 slidably mounted on the support rod 3 are fixed on both sides of the movable plate 6, and positioning rods 8 are horizontally arranged on the side of the sleeve 7 away from the movable plate 7. A rotating shaft is movably penetrated through the back side of the base 1 along the length direction, and connecting rods 9 are respectively arranged at both ends of the rotating shaft. The connecting rod 9 is perpendicular to the rotating shaft and the outer end is located on the front side of the base 1. An operating rod 10 is arranged between the outer ends of the connecting rod 9. The operating rod 10 drives the connecting rod 9 to rotate around the rotating shaft. A linkage rod 11 is hinged between the positioning rod 8 and the middle part of the connecting rod 9. The inspector bends the operating rod 10 to drive the connecting rod 9 to rotate around the rotating shaft, thereby driving the positioning rod 8 to move up and down, and the positioning rod 8 drives the sleeve 7 and the movable plate 6 to move along the support rod 3.
[0020] Furthermore, a limiting rod 12 is provided between the top ends of the support rods 3 to limit the movable plate 6 .
[0021] Furthermore, a hook 13 is hinged on one end of the limit rod 3, and the hook 13 is hooked on the rod body of the adjacent positioning rod 8. When no detection is performed or preparation for detection is performed, the positioning rod 8 is clamped on the hook 13 to prevent the movable plate from moving. When performing detection, the hook 13 can be removed.
[0022] During the test, test tubes containing multiple sampled soils are placed in the test tube racks respectively, analytical liquid is added to multiple syringes, and the syringes are placed in the positioning holes so that the syringes are opposite to the test tubes. The test personnel turn the operating lever to drive the connecting rod to rotate with the rotating shaft as the axis, thereby driving the positioning rod to move downward. The positioning rod drives the sleeve and the movable plate to move downward along the support rod. The movable plate squeezes the piston handles of several syringes at the same time, so that the analytical liquid in the syringes is injected into the test tube below. When multiple sampled soils are tested at the same time, the test time is greatly reduced and the labor intensity of the test personnel is reduced.
[0023] The above description is only a preferred feasible embodiment of the present utility model, and does not limit the scope of rights of the present utility model. All equivalent changes made using the contents of the present utility model specification and its drawings are included in the scope of rights of the present utility model.
