Description

Technical Field

[0001] This utility model belongs to the field of fertilizer testing and relates to fertilizer component analyzer technology, specifically a component analyzer for high magnesium content compound fertilizer. Background Technology

[0002] A fertilizer composition analyzer is an instrument specifically designed to analyze various nutrients (such as nitrogen, phosphorus, and potassium) in fertilizers. It typically uses optical, electrochemical, or chromatographic principles to detect the content of key nutrients in fertilizers, providing a scientific and reliable basis for agricultural production.

[0003] Existing fertilizer composition analyzers typically work by first processing the fertilizer to be tested into a clear filtrate, adding the appropriate reagents to the filtrate, turning on the analyzer, inserting the adjusted reagents for calibration and comparison, and then generating relevant data on the fertilizer to be tested.

[0004] During use, blank sample cuvettes, standard sample cuvettes, and sample cuvettes to be tested are typically placed sequentially inside the component analyzer. During this process, the light-shielding plate on the surface of the cuvette placement area needs to be opened and closed repeatedly. During measurement, the light-shielding plate is closed to ensure that the light fully illuminates the cuvettes. Therefore, during use, the light-shielding plate needs to be opened and closed manually multiple times, and the sample to be tested needs to be changed. This process takes up a considerable amount of the overall measurement time. Furthermore, when placing the cuvettes multiple times, it is necessary to ensure that the sample is placed in the designated position, which requires meticulous attention to detail to avoid errors.

[0005] Therefore, this utility model proposes a component analyzer for high magnesium content compound fertilizers. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a component analyzer for high-magnesium-content compound fertilizers. This analyzer solves the problem that existing compound fertilizer component analyzers require multiple opening and closing of the light-shielding plate and handling of cuvettes during use, a process that is time-consuming and cumbersome.

[0007] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a component analyzer for high-magnesium-content compound fertilizer is provided, comprising an analyzer housing, wherein a placement block and a detection block are fixedly connected inside the analyzer housing, and a conveying mechanism for conveying cuvettes is provided between the placement block and the detection block, the conveying mechanism comprising:

[0008] A conveyor belt is slidably connected to the placement block and the detection block. A plurality of conveying columns are rotatably connected to the surface of the conveyor belt. The plurality of conveying columns are spaced apart on the surface of the conveyor belt. The number of conveying columns is greater than or equal to six. A placement groove is opened on the side of the conveying column away from the conveyor belt. A limiting groove is opened on the surface of the placement block. Both the placement groove and the limiting groove are adapted to the cuvette.

[0009] Two conveyor wheels, both of which are connected to a conveyor belt drive;

[0010] The positioning block is rotatably connected to the detection block, and the side of the positioning block that contacts the cuvette is arc-shaped.

[0011] Optionally, a plurality of drive teeth are fixedly connected to the side of the conveyor wheel of the placement block away from the cuvette. The plurality of drive teeth are arranged in a ring array on the surface of the conveyor wheel. A drive rack is slidably connected inside the placement block, and the drive rack meshes with the drive teeth.

[0012] Optionally, a sliding column is slidably connected to the side of the drive rack away from the cuvette, and an annular groove is provided inside the placement block, with the sliding column adapted to the annular groove.

[0013] Optionally, a passive block is slidably connected to the side of the rack that is away from the analyzer housing, and a restoring spring is fixedly connected between the passive block and the placement block.

[0014] Optionally, the annular grooves have different depths, with the shallowest side closest to the drive tooth. The depth of the annular grooves increases or decreases at the turning positions, and the length of one side of the annular groove is equal to the distance between adjacent conveying columns.

[0015] Optionally, the passive block has a movable groove inside, and the driving rack is fixedly connected to a movable shaft, which is adapted to the movable groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The analyzer housing does not have a component area fixing block inside. Instead, a limiting groove adapted to the cuvette is opened on the surface of the placement block, ensuring that the cuvette slides along a rectangle inside the placement block and the detection block, thus preventing the cuvette from changing direction or position during movement. Furthermore, a rotating positioning block is set inside the detection block, with its surface contacting the cuvette in an arc shape. This provides some obstruction when the cuvette slides to the detection position, preventing inertia from causing the cuvette to shift position. The cuvette will also rotate and shift when it moves again, ensuring normal movement. Three conveyor columns are set on the conveyor belt surface, allowing all cuvettes to be measured to be placed on the conveyor belt surface at once, making operation simpler and faster.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1-4 As shown, a component analyzer for high-magnesium-content compound fertilizer includes an analyzer housing 1, inside which a placement block 2 and a detection block 3 are fixedly connected.

[0027] It should be noted that the analyzer housing 1 is divided into two areas, with the placement block 2 and the detection block 3 located in different areas. The detection block 3 is equipped with components such as a display screen, buttons, a printing mechanism, and a detection mechanism to realize cost analysis of the sample and output of results. The placement block 2 area is not equipped with any components and is only an area for placing sample containers and other detection auxiliary materials.

[0028] A conveying mechanism for transporting cuvettes is provided between the placement block 2 and the detection block 3. The conveying mechanism includes:

[0029] A conveyor belt 41 is slidably connected to the placement block 2 and the detection block 3. A plurality of conveying columns 42 are rotatably connected to the surface of the conveyor belt 41. The plurality of conveying columns 42 are spaced apart on the surface of the conveyor belt 41. The number of conveying columns 42 is a multiple of three and is greater than or equal to six. A placement groove 43 is provided on the side of the conveying column 42 away from the conveyor belt 41. A limiting groove 44 is provided on the surface of the placement block 2. Both the placement groove 43 and the limiting groove 44 are adapted to the cuvette.

[0030] Two conveyor wheels 45 are respectively rotatably connected to the placement block 2 and the detection block 3, and both conveyor wheels 45 are driven by the conveyor belt 41.

[0031] Positioning block 46 is rotatably connected to the detection block 3, and the side of positioning block 46 that contacts the cuvette is arc-shaped; a rotation spring (not shown in the figure) is provided between positioning block 46 and detection block 3.

[0032] In practical application, the analyzer for high-magnesium compound fertilizer has a component-free area fixed placement block 2 inside the analyzer housing 1. A limiting groove 44 adapted to the cuvette is formed on the surface of the placement block 2, ensuring that the cuvette slides along a rectangle within the placement block 2 and the detection block 3, thus preventing the cuvette from changing direction or position during movement. A rotating positioning block 46 is set inside the detection block 3, with an arc-shaped contact point between the positioning block 46 and the cuvette. This provides some obstruction when the cuvette slides to the detection position, preventing inertia from causing the cuvette to shift position. Furthermore, the cuvette rotates and shifts again when it moves, ensuring normal movement. Three conveyor columns 42 are set on the surface of the conveyor belt 41, allowing all cuvettes to be measured to be placed on the conveyor belt 41 at once, making operation simpler and faster.

[0033] In some specific implementations, a plurality of drive teeth 51 are fixedly connected to the side of the conveying wheel 45 located inside the placement block 2 away from the cuvette. The plurality of drive teeth 51 are arranged in a ring array on the surface of the conveying wheel 45. A drive rack 52 is slidably connected inside the placement block 2. The drive rack 52 and the drive teeth 51 mesh.

[0034] In a further embodiment, a sliding column 53 is slidably connected to the side of the drive rack 52 away from the cuvette; an annular groove 54 is provided inside the placement block 2; the sliding column 53 is adapted to the annular groove 54; a passive block 55 is slidably connected to the side of the drive rack 52 away from the analyzer housing 1; a restoring spring 56 is fixedly connected between the passive block 55 and the placement block 2; the length of one side of the annular groove 54 is equal to the distance between adjacent conveying columns 42.

[0035] In a further embodiment, the annular groove 54 has different depths, with the shallowest depth on the side of the annular groove 54 closest to the drive tooth 51, and the depth of the annular groove 54 increasing or decreasing at the turning position.

[0036] In a further embodiment, the passive block 55 has a moving groove 61 inside, and the moving shaft 62 is fixedly connected to the surface of the driving rack 52, and the moving shaft 62 is adapted to the moving groove 61.

[0037] The working principle of this utility model is as follows: Three cuvettes are placed inside the conveyor column 42 at the corresponding placement slot 43. Then, the rack 52 is slidably driven. The sliding of the rack 52 causes the drive tooth 51 to change position, which in turn drives the conveyor wheel 45 to rotate. The rotation of the conveyor wheel 45 causes the conveyor belt 41 to slide, which in turn causes the conveyor column 42 to change position and slide into the detection block 3. When the rack 52 slides to the reversing position of the annular groove 54, the surface of the cuvette contacts the positioning block 46. The internal components of the detection block 3 detect the cuvette. The rack 52 is released, and the rack 52 slides back to its original position under the action of the return spring 56. Since the side of the annular groove 54 away from the drive tooth 51 is deeper, the rack 52 will slide along the deeper groove to return to its position. At this time, the rack 52 will not cause the drive tooth 51 to change position. After the detection of a single cuvette is completed, the rack 52 is slidably driven again. After the detection of all cuvettes is completed, all cuvettes can be directly removed from the placement block 2.

[0038] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
