Description

Technical Field

[0001] This utility model belongs to the technical field of geological exploration equipment and relates to a portable geological sediment layering centrifuge device. Background Technology

[0002] Stratification of geological sediments aims to analyze their composition and sedimentary environment, primarily for the following applications: identifying mineral-rich strata in mineral exploration, detecting pollutant distribution in environmental monitoring, assessing soil bearing capacity in engineering geology, and reconstructing paleoenvironmental evolution in geological research. Stratification provides information on sediment grain size distribution, mineral composition, and chronology, offering crucial data support for resource assessment, environmental remediation, and basic research.

[0003] However, when geologists conduct sediment sampling in the field, they mainly use two stratification methods: one is the traditional gravity sedimentation method, which requires placing the sample in a graduated cylinder and waiting for more than 18 hours for natural sedimentation. This method is not only too time-consuming, but also easily affected by factors such as vibration in the field environment; the other is the laboratory centrifugation analysis method, which can complete stratification within 10 to 15 minutes, but the sample must be brought back to the laboratory for processing using large centrifuge equipment, which cannot meet the needs of on-site immediate testing. Both methods have obvious shortcomings in terms of timeliness and portability, which seriously restricts the efficiency of field work. Utility Model Content

[0016] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0018] like Figure 1 - Figure 4As shown, a portable geological sediment stratification centrifuge device includes a housing 101, with a rotating seat 102 rotatably connected to the inner side of the housing 101; multiple placement slots 103 are formed on the inner side of the rotating seat 102; sampling bottles 104 are installed on the inner side of the placement slots 103; a threaded block 105 is fixedly connected to the upper end of the housing 101; a cover 106 is provided at the upper end of the housing 101; the cover 106 is threadedly connected to the threaded block 105; a rotating frame 107 is provided on the inner side of the cover 106; a limiting ring 108 is fixedly connected to the upper end of the rotating frame 107; the limiting ring 108 is rotatably connected to the cover 106; a handle 109 is fixedly connected to the upper end of the cover 106; a compression assembly is provided on the inner side of the rotating frame 107; and a driving assembly is provided on the inner side of the housing 101.

[0019] The extrusion assembly includes an extrusion plate 201; the extrusion plate 201 is disposed on the inner side of the rotating frame 107; a spring 202 is disposed between the rotating frame 107 and the extrusion plate 201; the upper end of the spring 202 is fixedly connected to the rotating frame 107; the lower end of the spring 202 is fixedly connected to the extrusion plate 201; multiple sets of positioning blocks 203 are fixedly connected to the outer side of the extrusion plate 201; a positioning groove 204 is opened on the inner side of the rotating frame 107; the positioning block 203 is located inside the positioning groove 204 and is slidably connected to the positioning groove 204; a limit mechanism is disposed between the extrusion plate 201 and the rotating frame 107; a linkage mechanism is disposed between the extrusion plate 201 and the rotating seat 102. The elastic characteristics of the spring 202 and the positioning groove 204 limit the positioning block 203, thereby continuously pushing the extrusion plate 201 to move away from the rotating frame 107. Then, when the cap 106 and the outer shell 101 are threadedly connected by the threaded block 105, the extrusion plate 201 extrudes multiple sets of sampling bottles 104, thereby making the sampling bottles 104 more stable during later rotation.

[0020] The limiting mechanism includes a limiting block 301; multiple sets of limiting blocks 301 are fixedly connected to the outer side of the upper end of the extrusion plate 201; multiple sets of limiting grooves 302 are opened on the inner side of the rotating frame 107; the limiting block 301 is located inside the limiting groove 302 and is slidably connected to the limiting groove 302. When the outer shell 101 is separated from the cover 106, the limiting groove 302 limits the limiting block 301, thereby limiting the movement range of the extrusion plate 201 and preventing the positioning block 203 from sliding from the inside of the positioning groove 204.

[0021] The linkage mechanism includes a connecting cylinder 401; the connecting cylinder 401 is fixedly connected to the inner side of the middle part of the rotating seat 102; the inner side of the connecting cylinder 401 is provided with equally spaced serrated grooves 402; the lower end of the middle part of the extrusion plate 201 is fixedly connected with equally spaced serrated blocks 403; the equally spaced serrated blocks 403 are located inside the equally spaced serrated grooves 402 and are slidably connected to the equally spaced serrated grooves 402; The structural features of the serrated grooves 402 and the serrated blocks 403 make it easier for workers to insert the serrated blocks 403 into the inner side of the serrated grooves 402. When the rotating seat 102 rotates, the serrated grooves 402 and the serrated blocks 403 drive the extrusion plate 201 to rotate synchronously. The extrusion plate 201 then continuously fixes the sampling bottle 104 while it rotates.

[0022] The drive assembly includes a servo motor 501; the servo motor 501 is fixedly connected to the inner side of the housing 101; a drive gear 504 is fixedly connected to the output end of the servo motor 501; a connecting rod 502 is fixedly connected to the lower end of the rotating seat 102; the connecting rod 502 is rotatably connected to the housing 101; a driven gear 503 is fixedly connected to the outer side of the connecting rod 502; the driven gear 503 meshes with the drive gear 504. Start the servo motor 501, so that the output end of the servo motor 501 drives the drive gear 504 to rotate, and the drive gear 504 meshes with the driven gear 503, thereby driving the connecting rod 502 to rotate through the driven gear 503, which in turn drives the rotating seat 102 to rotate.

[0023] A control panel 601 is provided on the outer side of the housing 101; a battery 602 is provided on the inner side of the lower end of the housing 101. The servo motor 501 is started via the control panel 601, and the device is powered by the battery 602.

[0024] During operation, the sample bottle 104 is placed inside the placement slot 103, and then the cap 106 is put on the outside of the threaded block 105. The handle 109 is turned to rotate the cap 106, thereby connecting the outer shell 101 and the cap 106 together through the threaded block 105. When the lid 106 is rotated, the elasticity of the spring 202 causes the spring 202 to push the squeezing plate 201 toward the placement groove 103, thereby squeezing the sampling bottle 104 by the squeezing plate 201, thus preventing the sampling bottle 104 from detaching from the inside of the placement groove 103 due to centrifugal force during subsequent work. At the same time, during installation, the serrated block 403 is inserted into the inside of the serrated groove 402; Then, the servo motor 501 is started through the control panel 601, so that the output end of the servo motor 501 drives the drive gear 504 to rotate. Then, the drive gear 504 meshes with the driven gear 503, thereby driving the rotating seat 102 to rotate through the connecting rod 502. When the rotating seat 102 rotates, the structural design of the equally spaced serrated grooves 402 and equally spaced serrated blocks 403 drives the extrusion plate 201 to rotate. The structural design of the positioning block 203 and the positioning groove 204 causes the rotating frame 107 to rotate synchronously, which in turn causes the positioning block 203 to rotate synchronously with the rotating seat 102. When the placement groove 103 and the rotating seat 102 rotate synchronously, the sampling bottle 104 can be continuously extruded, making the sampling bottle 104 more stable when rotating.
