Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a sieving sampler for laboratory testing. Background Technology
[0002] A laboratory sieve sampler is a device used for sieving and sampling samples in the laboratory. It is widely used in research work in fields such as chemistry, physics, and biology. Its main purpose is to obtain representative small samples from a large number of raw materials or samples and to analyze or test them. The working principle of a sieve sampler is usually to use a sieve to physically sieve the sample, classify the sample according to particle size, and then obtain a sample suitable for analysis. In the existing technology, many laboratory sieving samplers are equipped with a fixed sampling device on the top to feed materials evenly into the sieve for sieving. However, there is a significant drawback in the existing design: the height of the feeding device cannot be adjusted. Different types of materials have different characteristics, such as particle size, moisture content, and viscosity, and their feeding requirements are also different. Therefore, in practical applications, the sieving effect often cannot reach the optimal level because the height of the feeding device cannot be adjusted. Specifically, because the feed height cannot be adjusted according to the characteristics of different materials, the screening device has poor adaptability to materials and cannot be optimized according to different material characteristics. Different materials may require different feed heights to ensure screening effect. At the same time, when the material particles are large, the moisture content is high, or the viscosity is strong, blockage or material accumulation may occur between the feed inlet and the feeding device, which is a problem that urgently needs to be solved. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, this utility model provides a sieving sampler for laboratory testing. This device, through the design of an adjustment component, a fastening component connected to the mounting frame, and a sampling shovel movably connected to the fastening component, solves the problem of the inability to adjust the height of the feeding device in existing technologies. When the operator starts the drive motor, the gears drive the meshing rack plates to move within the top plate, thereby adjusting the height of the sampling shovel through the mounting frame. This design allows for flexible adjustment of the sampling shovel height according to the feeding requirements of different materials, improving the adaptability of the sieving device to different materials. It can optimize feeding conditions based on material characteristics, ensuring the best sieving effect and avoiding the problem of poor sieving results due to a fixed height.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sieving sampler for laboratory testing, comprising a sieving sampler base plate, a support rod mounted on the sieving sampler base plate, a detection container assembly mounted on the outer wall of the support rod, a detection panel mounted on the side wall of the detection container assembly, a sieving funnel mounted on the outer wall of the support rod below the detection container assembly, a collection chamber mounted on the outer wall of the support rod below the sieving funnel, an adjustment assembly at the top of the support rod, a fastening assembly connected to the bottom of the adjustment assembly, and a sampling shovel mounted on the fastening assembly, wherein the sampling shovel is positioned above the detection container assembly.
[0005] As a preferred embodiment of the present invention, the detection container assembly includes a container cavity installed on the outer wall of the support rod, a feed inlet installed on the top outer wall of the container cavity, and a screening plate installed on the bottom outer wall of the container cavity.
[0006] In a preferred embodiment of this invention, the sidewall of the container cavity is connected to the detection panel, and the detection panel detects the sample inside the container cavity.
[0007] In a preferred embodiment of this utility model, the feed inlet is configured as a trumpet shape, the feed inlet is positioned directly below the sampling shovel, and the screening plate is positioned directly above the screening funnel.
[0008] As a preferred technical solution of this utility model, the adjustment component includes a top plate fixed to the outer wall of the top end of the support rod, a drive motor fixedly installed on the outer wall of the top plate, a gear installed on the output shaft of the drive motor, a rack plate slidably connected to the top plate, and an installation frame fixed to the outer wall of the bottom end of the rack plate. A fastening component is installed on the installation frame, and a sampling shovel is movably connected to the fastening component.
[0009] In a preferred embodiment of this utility model, the gear and the rack plate are meshed together, and the rotation of the gear drives the rack plate to move within the top plate.
[0010] As a preferred technical solution of this utility model, the fastening assembly includes a rotating shaft rotatably connected to the inner wall of the mounting frame, an extension screw mounted on the rotating shaft and penetrating the outer wall of the mounting frame, and a threaded nut block threadedly connected to the outer wall of the extension screw.
[0011] As a preferred embodiment of this utility model, a sampling shovel is connected to the rotating shaft, an extension screw is connected to one side of the rotating shaft, and the outer wall of the screw block is provided with anti-slip texture.
[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are: This device addresses the drawback of existing technologies where the height of the feeding device cannot be adjusted by designing an adjustment component, a fastening component connected to the mounting frame, and a sampling shovel movably connected to the fastening component. When the operator starts the drive motor, the gears drive the meshing rack plate to move within the top plate, which in turn drives the sampling shovel to adjust its height via the mounting frame. This design allows for flexible adjustment of the sampling shovel height according to the feeding requirements of different materials, improving the adaptability of the screening device to different materials. It can optimize feeding conditions based on material characteristics, ensuring the best screening effect and avoiding the problem of poor screening effect due to a fixed height.
[0013] This device optimizes the convenience and stability of feeding operations by designing a fastening component and connecting the rotating shaft to the sampling shovel. It indirectly helps solve the problems of material blockage and accumulation. When the operator rotates the nut block, the anti-slip texture increases the friction of the hand, making it easy to quickly release or lock the rotating shaft limit. When unlocked, the sampling shovel can rotate around the rotating shaft to accurately pour the sample into the feed port. When locked, the position of the sampling shovel can be fixed to prevent the sampling shovel from shifting during the material collection and pouring process, which would cause the material to spill. This design makes the sampling and pouring operations more precise and controllable, reduces material waste or accumulation caused by operational deviations, and further ensures the efficiency of screening and sampling.

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.
[0017] Example: like Figure 1-5 As shown, a sieving sampler for laboratory testing includes a sieving sampler base plate 1, a support rod 2 mounted on the sieving sampler base plate 1, a detection container assembly 3 mounted on the outer wall of the support rod 2, a detection panel 4 mounted on the side wall of the detection container assembly 3, a sieving funnel 5 mounted on the outer wall of the support rod 2 below the detection container assembly 3, a collection chamber 6 mounted on the outer wall of the support rod 2 below the sieving funnel 5, an adjustment assembly 7 mounted at the top of the support rod 2, the bottom end of the adjustment assembly 7 connected to a fastening assembly 8, and a sampling shovel 9 mounted on the fastening assembly 8, wherein the sampling shovel 9 is positioned above the detection container assembly 3. The detection container assembly 3 includes a container cavity 31 installed on the outer wall of the support rod 2, a feed inlet 32 installed on the top outer wall of the container cavity 31, and a screening plate 33 installed on the bottom outer wall of the container cavity 31. First, the staff uses the sampling shovel 9 to send the sample into the feed inlet 32. The sample falls into the container cavity 31 from the feed inlet 32. At this time, the detection panel 4 detects the sample. After the detection is successful, the electrical signal opens the sieve plate 33 to discharge the sample. The sample then falls from the sieve plate 33 for preliminary sieving into the sieve funnel 5. After passing through the sieve funnel 5 for a second sieving, the sample enters the collection cavity 6 for collection.
[0018] It is worth noting that the side wall of the container cavity 31 is connected to the detection panel 4. The detection panel 4 detects the sample inside the container cavity 31. This setting is to allow the detection panel 4 to directly act on the sample inside the container cavity 31, ensuring that the detection panel 4 can accurately perform detection operations on the sample entering the container cavity 31. The feed inlet 32 is designed in the shape of a trumpet. The trumpet-shaped structure can expand the receiving area of the feed inlet 32, making it easier for the sampling shovel 9 to pour the sample in smoothly and avoid spilling the sample. The feed inlet 32 is placed directly below the sampling shovel 9, which can ensure that the sample poured by the sampling shovel 9 falls accurately into the feed inlet 32, avoiding sample deviation and waste, and ensuring a smooth feeding process. The sieve plate 33 is placed directly above the sieve funnel 5, which can ensure that the sample after preliminary sieving by the sieve plate 33 can fall accurately into the sieve funnel 5. The adjustment assembly 7 includes a top plate 71 fixed to the outer wall of the top end of the support rod 2, a drive motor 72 fixedly installed on the outer wall of the top plate 71, a gear 73 installed on the output shaft of the drive motor 72, a rack plate 74 slidably connected to the top plate 71, and a mounting frame 75 fixed to the outer wall of the bottom end of the rack plate 74. A fastening assembly 8 is installed on the mounting frame 75, and a sampling shovel 9 is movably connected to the fastening assembly 8. The fastening assembly 8 includes a rotating shaft 81 rotatably connected to the inner wall of the mounting frame 75, an extension screw 82 installed on the rotating shaft 81 and penetrating the outer wall of the mounting frame 75, and a threaded nut block 83 threadedly connected to the outer wall of the extension screw 82. When the staff needs to adjust the height of the sampling shovel 9, they only need to turn on the external switch, which will start the drive motor 72. The drive motor 72 drives the gear 73 to rotate, and the rotation of the gear 73 drives the rack plate 74 to move. The rack plate 74 slides on the top plate 71, thereby driving the mounting frame 75 fixed at the bottom to move. The mounting frame 75 then drives the sampling shovel 9 connected to it to move, thus achieving height adjustment. When it is necessary to pour the sample from the sampling shovel 9 into the feed inlet 32, simply rotate the nut block 83 outward so that the nut block 83 and the extension screw 82 rotate outward together, so that the inner end wall of the nut block 83 separates from the outer wall of the mounting frame 75, thereby releasing the limit between the rotating shaft 81 and the mounting frame 75. At this time, the sampling shovel 9 can be rotated so that the sampling shovel 9 rotates within the mounting frame 75 through the rotating shaft 81, and the sample is poured into the feed inlet 32. Similarly, when placing the sample, simply place the sampling shovel 9 flat, and then rotate the nut block 83 to fit against the outer wall of the mounting frame 75, thereby limiting and fixing the rotation of the rotating shaft 81. Gear 73 and rack 74 are meshed together. The rotation of gear 73 drives rack 74 to move within top plate 71. This meshing connection is key to power transmission. Through this structure, when drive motor 72 drives gear 73 to rotate, it can effectively drive rack 74 to move within top plate 71, thereby driving mounting frame 75 and sampling shovel 9 to move, achieving height adjustment of sampling shovel 9. Sampling shovel 9 is connected to rotating shaft 81, providing a pivot point for sampling shovel 9 to rotate around rotating shaft 81. An extension screw 82 is connected to one side of rotating shaft 81. Through the cooperation of extension screw 82 and screw nut block 83, the rotating shaft 81 can be limited and unlocked. The outer wall of screw nut block 83 is provided with anti-slip texture, which can increase the friction when the operator operates screw nut block 83 and prevent hand slippage.
