Description

Technical Field

[0001] This utility model relates to the field of quartering method technology, and in particular to a simple quartering instrument for uniformly mixing samples. Background Technology

[0002] The quartering method specified in the national standard GB5491-1985 involves pouring the sample onto a smooth, flat table or glass plate, spreading the sample into a square using two dividing plates, then scooping up the sample from both sides about 10cm high and simultaneously pouring it down towards the center. Repeat this process in the opposite direction (keeping the center point in place), mixing the sample four or five times until it is spread into a square of equal thickness. Use the dividing plates to draw two diagonal lines on the sample, dividing it into four triangles. Take out two of the vertex triangles, and repeat the above method on the remaining sample until the last two vertex triangles are close to the required sample weight. Existing quartering apparatuses typically include a mixing device, a leveling device, and a quartering device. The mixing device usually consists of a mixing tank and motor-driven stirring blades located within the tank. However, such mixing devices have the following problems: 1. The mixed sample is cylindrical and cannot be directly used for quartering; 2. The stirring method limits the effective stirring range to a cylindrical area, creating a "stirring blind zone" that leads to uneven mixing; 3. When sampling with husks, the friction during stirring can cause the husks to fall off. If such samples are used for testing impurities, brown rice, etc., it will increase systematic errors, leading to overestimation or even exceeding of limits, resulting in inaccurate test results. Furthermore, manual quartering is significantly affected by human factors, exhibiting randomness and unpredictability. The sampled portions are often unevenly mixed, and the quality of the quartered samples varies greatly, failing to meet the requirement of uniform quartering. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a simple quartering apparatus for uniformly mixing samples.

[0004] The objective of this utility model is achieved through the following technical solution: A simple quartering method for uniform sample mixing includes a mixing device comprising a cuboid shell. The shell contains multiple layers of sample dividing plates, each consisting of four or more layers of first and second sample dividing plates, arranged alternately. The distance between adjacent layers is ≥10cm. Each first and second sample dividing plate is composed of two mirror-image sample dividing plates. The mirror axis of the two sample dividing plates of the first plate is perpendicular to that of the second plate. The mirror axes of the two sample plates are perpendicular. Each layer of sample plates has a rotating shaft on each side of the two sample plates facing each other. The housing has horizontal grooves on both sides of each sample plate. The rotating shafts on both sides of each sample plate slide in the corresponding grooves. Each layer of sample plates has rollers that can roll on the housing wall at the opposite ends of the two sample plates. Horizontal tie rods are hinged to the lower sides of the two sample plates facing each other at each end of the two sample plates. The housing has a through hole for each tie rod, and the end of the tie rod passes through the through hole.

[0005] Furthermore, the horizontal cross-section of the cuboid shell is square, and a receiving drawer is provided on the lower side of the bottom sample plate inside the shell. The outer side of the receiving drawer is fitted against the wall of the shell, and the shell has an opening on the side corresponding to the receiving drawer.

[0006] Furthermore, a partition plate is inserted into the receiving drawer. The partition plate is formed by two partitions connected vertically. The two partitions are located on the two diagonal lines of the receiving drawer. The partition plate divides the receiving drawer into four chambers, and each chamber is provided with an openable and closable discharge port.

[0007] Furthermore, the receiving drawer includes a square base plate with support columns at each of the four corners. The horizontal cross-section of the support columns is right-angled. Each side of the square base plate is hinged with a feeding plate, and the feeding plate is connected to the support columns on both sides by a locking structure.

[0008] Furthermore, the locking structure includes through holes on both sides of the feeding plate and bolts threaded onto the support columns on both sides of the feeding plate, with the ends of the two bolts extending into the two through holes respectively.

[0009] The beneficial effects of this utility model are: The simplified quartering apparatus for uniform sample mixing proposed in this invention involves pulling the levers on both sides of the top-layer sample dividing plate as the sample falls from top to bottom. Rollers on both sides of the plate roll upwards along the shell, while the rotating shafts on the two plates move in opposite directions along the slide groove. This results in the two plates forming an inverted V-shape. The sample falls at least 10cm to the next layer. After the sample has fallen completely, the levers on both sides of the plate are released, and the plate returns to its original shape under its own weight. Then, the levers on both sides of the next layer are pulled outwards, and this cycle repeats to ensure uniform mixing of the sample through multiple layers. The apparatus is simple in structure and easy to implement. This quartering apparatus eliminates mixing blind spots and is unaffected by human factors, achieving complete and more uniform mixing of all materials. Its principle is that gravity mixing prevents the shelled sample from falling off, thus not affecting subsequent testing.

[0010] The horizontal cross-section of the shell is made square, and the shell fits snugly against the receiving drawer. The mixed sample falls into the receiving drawer and, after being scraped flat, can be directly used for quartering.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0025] Example 1 like Figure 1-9 The simplified quartering apparatus shown includes a mixing device comprising a rectangular shell 1 with a square horizontal cross-section. The shell 1 contains multiple layers of sample dividers, each consisting of four layers of first sample dividers 2 and four layers of second sample dividers 3, arranged alternately. The distance between adjacent layers is 10 cm. Both first and second sample dividers 2 and 3 are composed of two sample divider bodies 4 arranged in a mirror image. The mirror axis of the two sample divider bodies 4 of the first sample divider 2 is perpendicular to the mirror axis of the two sample divider bodies 4 of the second sample divider 3. Figure 3 , 4As shown in Figures 7 and 8, each layer of sample plate has a rotating shaft 5 on each side of the two sample plate bodies 4 facing each other. The housing 1 has a horizontal sliding groove 6 on each side of each sample plate. The rotating shaft 5 on each side of each sample plate slides in the corresponding sliding groove 6. The middle part of the back end of each sample plate body 4 of each layer of sample plate has a roller 7 that can roll on the housing 1. The middle part of the lower side of the two sample plate bodies 4 facing each other of each layer of sample plate has a horizontal tie rod 8. The housing 1 has a through hole for each tie rod 8, and the end of the tie rod 8 passes through the through hole.

[0026] The simplified quartering apparatus for uniform sample mixing proposed in this invention involves pulling the levers 8 on both sides of the top-layer sample dividing plate as the sample falls from top to bottom. Rollers 7 on both sides of the plate roll upwards along the housing 1. Simultaneously, the rotating shafts 5 on the two sample dividing plates 4 move in opposite directions along the sliding grooves 6, ultimately forming an inverted V-shape. The sample falls at least 10cm to the next sample dividing plate. After the sample has fallen completely, the levers 8 on both sides of the plate are released, and the plate returns to its original shape under its own weight. Then, the levers 8 on both sides of the next sample dividing plate are pulled outwards. This process ensures that the sample is uniformly mixed by passing through multiple sample dividing plates sequentially. The structure is simple and easy to implement. This quartering apparatus eliminates mixing blind spots and is unaffected by human factors, achieving complete mixing of all materials for more uniform results. Its principle is that gravity mixing prevents the shelled sample from falling off, thus not affecting subsequent testing.

[0027] Example 2 Based on Example 1, such as Figure 10-11 As shown, a receiving drawer 9 is provided on the lower side of the bottom sample plate inside the housing 1. The outer side of the receiving drawer 9 is flush with the wall of the housing 1, and the distance between the inner bottom surface of the receiving drawer 9 and the bottom sample plate is 10cm. The housing 1 has an opening on one side corresponding to the receiving drawer 9. The receiving drawer 9 includes a square base plate 10, with support columns 11 at the four corners of the square base plate 10. The horizontal cross-section of the support columns 11 is right-angled. A feeding plate 12 is hinged to each side of the square base plate 10, and the feeding plate 12 is connected to the support columns 11 on both sides by a locking structure. There are many types of locking structures. For example, the locking structure includes through holes 13 on both sides of the feeding plate 12 and bolts 14 threadedly connected to the support columns 11 on both sides of the feeding plate 12. The ends of the two bolts 14 can extend into the two through holes 13 respectively. Rotating the two bolts 14 allows their ends to extend into or exit from the two through holes 13. A divider 15 is inserted into the receiving drawer 9. The divider 15 is formed by two partitions connected vertically. The two partitions are located on the two diagonal lines of the receiving drawer 9, and the divider divides the receiving drawer 9 into four cavities.

[0028] After the sample passes through the mixing device of Example 1, it is collected by the receiving drawer 9. After collection, the receiving drawer 9 is pulled out, and the sample inside the receiving drawer 9 is leveled with a scraper. The partition plate 15 is inserted into the receiving drawer 9, at which point the sample inside the receiving drawer 9 is divided into four equal parts. The two opposing cavities are opened by the locking structure, allowing the sample in them to re-enter the housing 1 from the top. The samples in the other two opposing cavities are placed in the waste collection box, and a second mixing, leveling, and division are performed until the sample reaches the required amount. The horizontal cross-section of the housing 1 is made square, and the housing 1 is fitted with the receiving drawer 9. The mixed sample falls into the receiving drawer 9, and after leveling, it can be directly used for division.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution 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 solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
