Description

Technical Field

[0001] This utility model relates to the technical field of biological sample processing devices, specifically a marine sediment sample grinding device. Background Technology

[0002] Marine sediments, as an important component of the marine environment, contain a wealth of information and are of key significance for studying marine ecosystems, climate change, and geological evolution. When analyzing marine sediments, they need to be ground into appropriate particle sizes so that they can be fully incorporated into the test solution for accurate analysis of their composition. This makes marine sediment sample grinding equipment an indispensable tool in the field of marine scientific research.

[0003] However, traditional marine sediment sample grinding techniques have many drawbacks. Some equipment often experiences frequent blockages during the feeding process due to the large amount of sample poured in at once. If manual unblocking is required, the grinding efficiency will be severely affected. On the other hand, using vibration to unblock the sample can damage the precision components inside the equipment and shorten its service life. Furthermore, traditional equipment cannot ensure that all sediments are fully ground during discharge, and there are often samples that have not been ground properly mixed in. This requires secondary screening, which greatly increases the workload and time cost, and seriously affects the efficient conduct of marine sediment research. To address these issues, we propose a marine sediment sample grinding device. Utility Model Content

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] A grinding device for marine sediment samples is provided, which has the following advantages:

[0017] 1. This marine sediment sample grinding equipment, through auxiliary grinding components, allows for rapid material entry via gravity through the top feed inlet. The front side feed design facilitates manual addition of small sample amounts, while the side feed inlet can be used with automated feeding equipment to meet continuous feeding needs. Operators can flexibly choose the feeding method according to the actual working scenario and sample characteristics. Simultaneously, the trapezoidal feed inlet increases the feeding area, allowing material to enter the equipment more smoothly, and the funnel-shaped feed trough guides the material, significantly reducing spillage and waste during the feeding process, laying the foundation for a smooth grinding process. In the sieving stage, the grinding wheel ring... The equidistantly distributed sieve grooves and the equally distributed circular sieve holes on the sieve wheel together constitute the sieving system. During the grinding process, marine sediment samples that meet the particle size requirements can pass through the sieve grooves of the grinding wheel into the sieve wheel, and then fall into the discharge port through the sieve holes of the sieve wheel, and finally be collected in the drawer groove. The scientific distribution of multiple sets of sieve grooves and sieve holes ensures the comprehensiveness and efficiency of the screening, effectively avoiding over-grinding. This sieving mechanism makes the output sample particle size highly consistent, greatly improving the sample quality, reducing research errors and repetitive work caused by poor sample quality, and helping scientific research to proceed smoothly based on high-quality samples.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A marine sediment sample grinding device includes a housing 1, a motor housing 2 and a collection drawer 3. The motor housing 2 is fixedly installed on the rear side of the housing 1. A drawer groove 4 is opened at the bottom of the housing 1, and the collection drawer 3 is slidably installed inside the drawer groove 4.

[0026] The grinding assembly is located inside the outer casing 1. The outer casing 1 has a circular blind hole corresponding to the inside of the motor housing 2. The grinding assembly includes a rotating structure, a sliding structure, and a grinding rod 5. The rotating structure includes a planetary gear 6, a sealing plate 7, a grinding wheel 8, a sieve groove 9, a baffle 10, and a slide rail 11. The planetary gear 6 is fixedly installed on the motor shaft of the motor housing 2, and the sealing plate 7 is fixedly installed on the side of the planetary gear 6 away from the motor housing 2. The sealing plate 7 has a through hole on the side corresponding to the center of the secondary gear of the planetary gear 6, and the grinding rod 5 is fixedly installed on the secondary gear of the planetary gear 6 through the through hole. The grinding wheel 8 has a sieve groove 9 on its side, and the baffle 10 is fixedly installed on both sides of the grinding wheel 8 corresponding to the sieve groove 9. The dovetail-shaped slide rail 11 is fixedly installed on both sides of the grinding wheel 8 corresponding to the baffle 10. The baffle 10 can prevent the material from accidentally splashing out of the grinding wheel 8 from the sieve groove 9 during the grinding process, ensuring that the material is always ground and screened within the working area formed by the grinding wheel 8 and the sieve wheel 12, thereby improving the material utilization efficiency.

[0027] The sliding structure includes a screen wheel 12, screen holes 13, a sliding groove 14, and grinding discs 15. The screen wheel 12 has circular screen holes 13 on its side, and a dovetail-shaped sliding groove 14 is fixedly installed on the inner side wall of the screen wheel 12. The sliding groove 14 is slidably connected to the slide rail 11. The grinding discs 15 are fixedly installed on the inner side wall of the screen wheel 12 corresponding to the screen holes 13. The grinding discs 15 are frictionally connected to the side of the grinding wheel 8. The screen wheel 12 is fixedly installed in the blind hole of the outer shell 1. The circular design of the screen holes 13 allows materials that meet the particle size requirements to pass through more smoothly. When the material passes through, the edge of the screen holes 13 can also play a certain secondary grinding role on the material, further refining the material particles and improving the grinding quality of the material.

[0028] An auxiliary grinding component is provided on the top of the outer casing 1, and auxiliary grinding components are provided on the front and sides of the grinding component.

[0029] Furthermore, the outer casing 1 is a rectangular block, and a motor slot is opened on the rear side of the outer casing 1. The motor box 2 is fixedly installed on the rear side of the outer casing 1 through the motor slot. The design of the motor slot makes the center of gravity of the motor box 2 more reasonably distributed with the center of gravity of the outer casing 1 after installation, which enhances the overall stability of the equipment and avoids the equipment shaking due to the center of gravity shift when the motor is working.

[0030] Furthermore, the grinding wheel 8 is a hollow cylinder with a hollow interior, and the sealing plate 7 is fixedly installed on the inner side wall of the grinding wheel 8. Three sets of grinding rods 5 are distributed in a ring at equal intervals, and the sides of the grinding rods 5 are connected to the inner side wall of the grinding wheel 8 through frictional engagement. Multiple sets of screen grooves 9 are distributed in a ring at equal intervals, two sets of baffles 10 are distributed axially symmetrically, and two sets of slide rails 11 are distributed axially symmetrically. The hollow cylindrical grinding wheel 8 provides ample grinding space for the material, and during rotation, centrifugal force can be used to distribute the material more evenly in the grinding area. Combined with the ring-shaped equidistantly distributed screen grooves 9, the material can be screened more efficiently while being ground.

[0031] Furthermore, the sieve wheel 12 is a hollow cylinder with an internal hollow structure, and the inner diameter of the sieve wheel 12 is equal to the outer diameter of the grinding wheel 8. The sieve holes 13 are distributed in an annular pattern at equal intervals, and the two sets of sliding grooves 14 are distributed axially symmetrically. The five sets of grinding discs 15 are distributed in an annular pattern at equal intervals. The design that the inner diameter of the sieve wheel 12 is equal to the outer diameter of the grinding wheel 8 ensures that the grinding gap remains consistent when the two rotate relative to each other, avoiding uneven grinding of materials due to gap changes. The annularly distributed grinding discs 15 can grind the material on the side of the grinding wheel 8 from multiple angles.

[0032] Furthermore, the auxiliary grinding component includes a feed inlet 16 and a feed trough 17. The front side of the outer shell 1 corresponding to the blind hole has a trapezoidal feed inlet 16, and the feed inlet 16 extends longitudinally through the side wall of the outer shell 1 and connects to the blind hole inside the outer shell 1. The side of the outer shell 1 corresponding to the feed inlet 16 has a funnel-shaped feed trough 17 fixedly installed. The funnel-shaped design of the feed trough 17 can guide the material to the feed inlet 16 in a concentrated manner, reducing the loss of material during the feeding process. The larger opening end of the trapezoidal feed inlet 16 faces upward, making it convenient for the operator to pour the material in. The smaller opening end is connected to the internal blind hole, which allows the material to enter the grinding area more accurately.

[0033] Furthermore, the auxiliary grinding component also includes a discharge port 18. A through-hole is formed inside the outer shell 1 at the position directly below the blind hole, and the through-hole vertically connects the blind hole and the drawer groove 4 inside the outer shell 1. A funnel-shaped discharge port 18 is fixedly installed on the inner side wall of the through-hole. The funnel-shaped structure of the discharge port 18 can collect the material discharged from the screen hole 13, so that the material can fall more concentratedly into the collection drawer 3 in the drawer groove 4. The through-hole design provides a smooth channel for the material discharge and avoids the material from getting blocked during the discharge process.

The planetary gear 6, through the secondary gear, causes the grinding rod 5 to rotate synchronously. The grinding rod 5 rubs against the inner wall of the hollow cylindrical grinding wheel 8, performing preliminary grinding on the marine sediment sample entering the grinding wheel 8. On the other hand, the planetary gear 6 drives the sealing plate 7 and the grinding wheel 8 to rotate. The grinding wheel 8 slides with the dovetail-shaped slide rail 11 and the sliding groove 14 inside the sieve wheel 12.
