Description

Technical Field

[0001] The utility model belongs to the technical field of solid sampling, and in particular relates to a device for automatic vertical sampling of solid samples. Background Art

[0002] Solid sampling is a basic and important step in laboratory analysis, quality control, research and development, etc. It involves taking representative samples from a large amount of solid materials to ensure the accuracy and reliability of subsequent test or test results. There are many different methods for solid sampling, depending on the properties of the solid (such as particle size, uniformity, hardness, fragility, etc.), sample volume requirements, sampling purpose, and safety considerations.

[0003] Authorization announcement number "CN213209556U" discloses a viscous solid sampling device, including a hollow outer cylinder, a hollow inner cylinder is slidably provided inside the outer cylinder; a sealing rubber plug is slidably provided on the inner cylinder, and the sealing rubber plug is connected to a pull rod; a sampling port is penetrated on one side of the outer cylinder, a sampling port adapted to the sampling port is penetrated on the inner cylinder, and a scraper is provided at the vertical opening of the sampling port. The spike portion can increase the pressure of the needle tip, so that the sampling device can enter the solid to be sampled more easily, and the scraper can cover or open the sampling port by rotating the inner cylinder. When the scraper opens the sampling port, rotating the outer cylinder can cause the scraper to generate a force on the surrounding solids, so that the harder solids are scraped off and enter the inner cylinder through the sampling port and the sampling port. At the same time, the pull rod is pulled up to form a negative pressure between the inner cylinder and the solid sample, so that the solid sample enters the inner cylinder more quickly, thereby speeding up the sampling process.

[0004] The above new type creates negative pressure between the inner cylinder and the solid sample, prompting the solid sample to enter the inner cylinder more quickly, thereby speeding up the sampling process. However, when sampling solid materials, the above new type can only sample materials at one level and cannot effectively analyze the differences in material composition at different levels.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0028] A device for automatically sampling solid samples vertically, comprising:

[0029] Motor 1;

[0030] A rotating rod 2, the rotating rod 2 is fixedly connected to the extended end of the motor 1;

[0031] A material taking component, which includes a fixed sleeve 3, a drill bit 4, an auger 5, a sampling barrel 6, a sampling slot 7, a spring push plate 8, and a support spring 9. There are two sampling barrels 6 and two sampling slots 7, and there are multiple support springs 9. The fixed sleeve 3 is fixedly connected to the circumferential surface of the rotating rod 2, the drill bit 4 is fixedly connected to the lower end of the rotating rod 2, the auger 5 is fixedly connected to the circumferential surface of the rotating rod 2, the two sampling barrels 6 are slidably connected in the fixed sleeve 3, the two sampling slots 7 are respectively opened in the two sampling barrels 6, the spring push plate 8 is slidably connected in the fixed sleeve 3, and the multiple support springs 9 are fixedly connected to the lower inner wall of the fixed sleeve 3 and the lower end of the spring push plate 8;

[0032] The contact sensor 11 is fixedly connected to the lower inner wall of the fixed sleeve 3 .

[0033] In a specific embodiment of the present utility model, the lifting mechanism is fixed to the motor 1 to drive the motor 1 up and down, thereby driving the rotating rod 2 to move and sample the material in the solid material barrel. When sampling, two sampling barrels 6 are inserted into the fixed sleeve 3, and the lower end of the sampling barrel 6 contacts the upper end of the spring push plate 8. The motor 1 drives the rotating rod 2 to rotate, and the drill bit 4 drills the compacted and hardened solid materials to loosen them when moving downward. When the rotating rod 2 continues to move downward, the materials loosened by the drill bit 4 are accumulated on the auger 5, and the loosened materials are transported upward into the fixed sleeve 3 through the rotation of the auger 5. As the materials accumulate, more materials are transported by the auger 5, and the materials fall into the sampling slot 7 through the side partition of the sampling slot 7 to complete the collection, and the drill bit 4 is lifted and lowered. The mechanism drives the material to move downward toward the material barrel to continuously replenish the sampling slot 7. The material that falls into the lower layer of the sampling slot 7 is the upper layer of the material barrel, and the upper layer is the lower layer of the material barrel. When the sampled material accumulates in the sampling slot 7, the weight of the sampling slot 7 gradually increases, squeezing the spring push plate 8 to move downward and squeeze multiple supporting springs 9 to contract. When the spring push plate 8 moves to the contact sensor 11 and contacts the upper end of the spring push plate 8, the contact sensor 11 sends a contact signal to drive the lifting mechanism to raise the fixed sleeve 3 to complete the sampling. After the sampling is completed, the lifting mechanism pulls the fixed sleeve 3 out of the material barrel, and then pulls the sampling barrel 6 out of the fixed sleeve 3 to complete the sampling. The fixed sleeve 3 descends at a uniform speed to enable the device to uniformly sample different deep layers of the solid material.

[0034] For details, please refer to Figure 1-Figure 4 The lower end of the sampling tube 6 is fixedly connected with a feed plate 21 , and the lower end of the fixed sleeve 3 is provided with a feed port 10 , and the feed plate 21 slides in the feed port 10 .

[0035] In this embodiment: a portion of the lower end of the fixed sleeve 3 is connected to the surface of the rotating rod 2, and the remaining portion is a feed port 10 so that the material can enter the fixed sleeve 3. The feed plate 21 is inserted in the feed port 10 to guide the material and prevent the material from falling into the fixed sleeve 3.

[0036] For details, please refer to Figure 1-Figure 4 A pull plate 13 is fixedly connected to the upper end of the sampling tube 6 , and a material introduction chamfer 12 is provided on the circumferential surface of the fixed sleeve 3 .

[0037] In this embodiment: the pull plate 13 is fixed on the fixed sleeve 3. When the sampling is completed, the operator buckles the pull plate 13 with his fingers to pull the sampling tube 6 out of the fixed sleeve 3. The material guide chamfer 12 is arranged at the lower end of the fixed sleeve 3 as an inclined surface. Except for the material pushed into the feed port 10 by the auger 5, the remaining material is pushed to the outside of the fixed sleeve 3 through the material guide chamfer 12, which will not affect the downward movement of the drill bit 4.

[0038] For details, please refer to Figure 1-Figure 4 A base 14 is provided on one side of the motor 1, and a lifting platform 20 is provided on the upper side of the base 14. A driving cylinder 18 is fixedly connected to the upper end of the lifting platform 20. The driving cylinder 18 is connected to the contact sensor 11 signal. A lifting rod 19 is fixedly connected to the extended end of the driving cylinder 18. The lifting rod 19 penetrates the lifting platform 20 and is connected to the upper end of the base 14. The lifting platform 20 is fixedly connected to the outer surface of the motor 1.

[0039] In this embodiment: the lifting platform 20 is sleeved outside the motor 1 to fix the motor 1, the lower end of the lifting rod 19 is fixed to the base 14, and the upper end is fixed to the extended end of the driving cylinder 18. When sampling is required, the extended end of the driving cylinder 18 is shortened to make the lifting platform 20 descend, and the motor 1 drives the drill bit 4 to rotate to make the sampling component go deep into the material barrel. When the spring push plate 8 contacts the contact sensor 11, an extension signal is sent out, so that the extended end of the driving cylinder 18 is extended to pull the fixed sleeve 3 out of the material barrel.

[0040] For details, please refer to Figure 1-Figure 4 The upper end of the lifting platform 20 is provided with two limiting slide grooves 17 , and the upper end of the base 14 is fixedly connected with two limiting slide rods 16 , and the two limiting slide rods 16 slide in the two limiting slide grooves 17 respectively.

[0041] In this embodiment, the limiting slide bar 16 passes through two limiting slide grooves 17, and the limiting slide bar 16 is used to limit the up and down movement of the lifting platform 20, so that the lifting platform 20 will not deviate when moving.

[0042] For details, please refer to Figure 1-Figure 4 A supporting groove 23 is formed on the circumferential surface of the rotating rod 2 , and a supporting plate 22 is fixedly connected to the lower end of the lifting platform 20 , and the supporting plate 22 is sleeved outside the supporting groove 23 .

[0043] In this embodiment, the support plate 22 rotates in the support groove 23 , and the support plate 22 directly supports the rotating rod 2 , thereby avoiding the output end of the motor 1 from being weighed first and protecting the motor 1 .

[0044] It should be noted that the motor 1, contact sensor 11 and driving cylinder 18 used in the device are all prior art and will not be described in detail here.

[0045] The working principle and use process of the utility model are as follows: the lifting mechanism is fixed to the motor 1 to drive the motor 1 to move up and down, thereby driving the rotating rod 2 to move and sample the material in the solid material tube. When sampling, two sampling tubes 6 are inserted into the fixed sleeve 3, and the lower end of the sampling tube 6 contacts the upper end of the spring push plate 8. The motor 1 drives the rotating rod 2 to rotate, and the drill bit 4 drills the compacted and hardened solid materials to loosen them when moving downward. When the rotating rod 2 continues to move downward, the materials loosened by the drill bit 4 are accumulated on the auger 5, and the loosened materials are transported upward into the fixed sleeve 3 through the rotation of the auger 5. As the materials accumulate, more materials are transported by the auger 5, and the materials fall into the sampling slot 7 through the side partition of the sampling slot 7 to complete the collection, and the drill bit 4 is lifted. The descending mechanism drives the material to move downwardly toward the material barrel to continuously replenish the sampling slot 7. The material that falls into the lower layer of the sampling slot 7 is the upper layer of the material barrel, and the upper layer is the lower layer of the material barrel. When the sampled material accumulates in the sampling slot 7, the weight of the sampling slot 7 gradually increases, squeezing the spring push plate 8 to move downward and squeeze multiple supporting springs 9 to contract. When the spring push plate 8 moves to the contact sensor 11 and contacts the upper end of the spring push plate 8, the contact sensor 11 sends a contact signal to drive the lifting mechanism to raise the fixed sleeve 3 to complete the sampling. After the sampling is completed, the lifting mechanism pulls the fixed sleeve 3 out of the material barrel, and then pulls the sampling barrel 6 out of the fixed sleeve 3 to complete the sampling. The fixed sleeve 3 descends at a uniform speed to enable the device to uniformly sample different deep layers of the solid material.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
