Abstract
Description
Technical Field
[0001] This utility model relates to a sample uniform distributor for wheat quality testing, belonging to the field of wheat quality testing technology. Background Technology
[0002] Wheat quality testing is a crucial step in ensuring food security, grading and pricing, and processing suitability. To guarantee the accuracy of test results, the wheat samples to be tested must be uniformly mixed before testing, meaning the wheat grains must be evenly distributed. Ensuring the uniform distribution of the wheat sample is paramount; uneven distribution can lead to inaccurate test results.
[0003] In existing technologies, wheat grains are typically evenly distributed using either the quartering method or a horizontal divider. The quartering method involves first pouring the wheat sample onto a smooth, flat surface to form a square of uniform thickness. Then, using a dividing plate, two diagonal lines are drawn across the sample, dividing it into four identical triangles. Two of these triangles are then used as samples, and the remaining portions are mixed repeatedly to obtain a uniformly distributed sample. The horizontal divider includes a square outer cylinder and partitions evenly distributed within the outer cylinder. The partitions divide the outer cylinder into an even number of discharge channels. Discharge outlets are located at the bottom of each discharge channel and are divided into two rows, with adjacent outlets in different rows. Two receiving baskets are placed below each row of outlets. The divider also includes a filling basket. To use this method, place the wheat grains to be mixed evenly into the feeding basket and spread them flat. Then, tilt the feeding basket to pour the wheat grains evenly into the various discharge channels of the horizontal format sampler. The wheat grains will then fall into the receiving basket below through the discharge channels. Wheat grains passing through two adjacent discharge channels will fall into different receiving baskets. Repeat this process several times to evenly distribute the wheat grains. However, the quartering method requires a high level of operator skill. Before sampling, the wheat sample needs to be spread into a square of equal thickness. During sampling, the square sample needs to be divided into four identical triangles; otherwise, the wheat sample cannot be evenly distributed, making the operation inconvenient. Similarly, the horizontal format sampler requires a high level of operator skill. Before feeding, the wheat grains in the feeding basket need to be spread flat. During feeding, the bottom wall of the feeding basket should be parallel to the side wall of the horizontal format sampler; otherwise, the wheat grains cannot be evenly mixed, making the operation inconvenient. Furthermore, if there are clumps in the wheat sample, the horizontal format sampler cannot disperse the clumps, resulting in uneven mixing of the wheat grains. Utility Model Content
[0004] The purpose of this invention is to provide a sample uniform distributor for wheat quality testing, so as to solve the problem of inconvenient operation when uniformly distributing wheat samples in the prior art.
[0005] To solve the above problems, the sample uniform distributor for wheat quality testing involved in this utility model adopts the following technical solution: A sample uniform distributor for wheat quality testing includes a support frame, which includes a first support plate. A uniform distribution cylinder, extending vertically through the first support plate, is suspended on the support frame. The uniform distribution cylinder includes an outer cylinder with openings at the top and bottom and a uniform distribution core disposed within the outer cylinder. Several partitions, arranged circumferentially and evenly, extend from the sidewall of the uniform distribution core. The sides of the partitions away from the uniform distribution core are gradually sloping downwards. The partitions extend to the inner wall of the outer cylinder and divide the outer cylinder into several guide channels. The guide channels are arranged in pairs, with a discharge port at the lower part of each channel. The discharge ports of two alternating guide channels are evenly distributed on the same virtual circle, while the discharge ports of two adjacent guide channels are located on different virtual circles. A material dispersing component is provided at the top of the uniform distribution core. A feeding hopper is provided at the upper part of the uniform distribution cylinder, with a feeding port and an injection port at the upper and lower ends of the feeding hopper, respectively. The injection port is located directly above the material dispersing component, and the inner diameter of the injection port is smaller than the diameter of the bottom circle of the material dispersing component.
[0006] The top of the bulk component is provided with spikes.
[0007] The discharge port includes an inner discharge port and an outer discharge port. The inner discharge port is the lower port of the guide channel, and the outer discharge port extends out of the side wall of the outer cylinder.
[0008] The outer cylinder has a notch on its side wall, and an extension plate is provided on the extension line of the partition. The extension plate extends out of the side wall of the outer cylinder from one side of the notch. An inclined plate extends out of the evenly distributed core and extends to the adjacent partition and extension plate on both sides. The inclined plate extends out of the side wall of the outer cylinder at the bottom of the notch. The inclined plate and the extension plates on both sides of the inclined plate form an extension groove. The discharge port is the lower port of the extension groove.
[0009] The bulk component is a cone shape, smaller at the top and larger at the bottom.
[0010] The first support plate has a first support hole, and the upper edge of the equalizing cylinder is provided with a first outward flange. The equalizing cylinder is supported in the first support hole of the first support plate through the first outward flange.
[0011] A second support plate is provided on the bracket above the first support plate. The second support plate has a second support hole. The upper edge of the feeding hopper is provided with a second outward flange. The feeding hopper is supported in the second support hole of the second support plate through the second outward flange.
[0012] A retaining ring is provided between the inner discharge port and the outer discharge port, and the retaining ring is located on the extension line of the outer cylinder side wall.
[0013] Below the equalizing cylinder are an inner material receiving basket and an outer material receiving basket. The inner material receiving basket is located below each inner discharge port, and the outer material receiving basket is located below each outer discharge port.
[0014] The bottom wall of the outer material basket has a protruding post, and the bottom wall of the inner material basket has a groove. The inner material basket is stacked in the outer material basket through the cooperation of the protruding post and the groove.
[0015] The equalizing cylinder of this invention has a material dispersing component at the top of its equalizing core. The feeding port of the hopper is located directly above the material dispersing component, and the inner diameter of the feeding port is smaller than the diameter of the bottom circle of the material dispersing component. After the wheat sample falls into the equalizing cylinder from the feeding port, it all falls onto the material dispersing component and is then evenly dispersed by it. Several partitions are evenly arranged in a circumferential direction extending from the side wall of the equalizing core. The side of the partitions away from the equalizing core is a gradually downward sloping arc surface. The partitions extend to the inner wall of the outer cylinder and divide the outer cylinder into several guide channels. The lower part of the guide channels is provided with a discharge port, which is alternately arranged in two... The outlets of the guide channels are evenly distributed on the same virtual circle, with the outlets of adjacent guide channels located on different virtual circles. Wheat grains from the wheat sample fall randomly and evenly from the bulk material onto the arc surfaces of the partitions and into the guide channels. The gradually downward-sloping arc surfaces prevent the wheat grains from lingering, causing them to fall from the arc surfaces into the guide channels. The wheat grains then slide along the guide channels towards the outlets and fall from the outlets. Wheat grains from adjacent guide channels fall into different virtual circles, thus evenly distributing the wheat sample. Using this sample distributor for wheat quality testing, the operation is simple and convenient. Attached Figure Description

[0020] Specific embodiments of the sample uniform distributor for wheat quality testing involved in this utility model are described below. Figures 1-11The system includes a support frame 1 as its foundation, a first support plate 2, and a distribution cylinder 3 suspended above and below the first support plate 2. The distribution cylinder 3 includes an outer cylinder 4 with openings at the top and bottom and a distribution core 5 disposed within the outer cylinder 4. The distribution core 5 is truncated cone-shaped, and several partitions 6 are evenly arranged circumferentially on the sidewalls of the distribution core 5. The side of the partitions 6 away from the distribution core 5 is a gradually downward sloping arc surface, which makes it difficult for wheat grains to remain, thus reducing the risk of grain jamming. The partitions 6 extend to the inner wall of the outer cylinder 4 and divide the outer cylinder 4 into several inclined guide channels 7. Adjacent partitions 6 form the sidewalls of the guide channels 7, and the sidewalls of the distribution core 5 form the bottom wall of the guide channels 7. The guide channels 7 are arranged in pairs, and the lower part of the guide channels 7 is provided with... The equalizing cylinder 3 is equipped with a discharge port. The discharge ports of two alternating guide channels 7 are evenly distributed on the same virtual circle, and the discharge ports of two adjacent guide channels 7 are located on different virtual circles. The top of the equalizing core 5 is equipped with a material dispersing component 8, which is used to evenly disperse the wheat grains falling on it to its outer periphery. The upper part of the equalizing cylinder 3 is equipped with a feeding hopper 9 for feeding. The upper and lower ends of the feeding hopper 9 are respectively equipped with a feeding port 10 and a feeding port 11. The feeding port 10 is used to add wheat samples to the feeding hopper 9, and the feeding port 11 is used to inject the wheat samples in the feeding hopper 9 into the equalizing cylinder 3. The feeding port 11 is located directly above the material dispersing component 8. The inner diameter of the feeding port 11 is smaller than the diameter of the bottom circle of the material dispersing component 8. All the wheat grains injected from the feeding port 11 fall onto the material dispersing component 8 and are evenly dispersed by the material dispersing component 8.
[0021] Specifically, the top of the bulk material component 8 is provided with a spike, which is a spike 14 inserted into the bulk material component 8. A cylindrical groove is opened on the top of the bulk material component 8, and the spike 14 is inserted into the cylindrical groove. When the wheat sample falls into the equalization cylinder 3 from the feeding port 11, the spike 14 can pierce the clumps in the wheat sample, thereby dispersing the wheat grains in the clumps and preventing the clumps from affecting the uniform mixing of wheat grains; the spike can be replaced.
[0022] Specifically, the discharge port is divided into an inner discharge port 12 and an outer discharge port 13. The inner discharge port 12 is the lower port of the guide channel 7, and the outer discharge port 13 extends out of the side wall of the outer cylinder 4.
[0023] Specifically, a notch is provided on the side wall of the outer cylinder 4, and an extension plate 15 is provided on the extension line of the partition plate 6. The extension plate 15 extends out of the side wall of the outer cylinder 4 from one side of the notch. Inclined plates 16 are provided on both sides of the evenly distributed core 5, extending to the adjacent partition plate 6 and the adjacent extension plate 15. The inclined plates 16 extend out of the side wall of the outer cylinder 4 at the bottom of the notch. The inclined plates 16 and the extension plates 15 on both sides of the inclined plates 16 form an extension groove 17. The discharge port 13 is the lower port of the extension groove 17.
[0024] Specifically, the bulk material component 8 is a cone shape, smaller at the top and larger at the bottom. The cone-shaped bulk material component 8 can evenly disperse the wheat grains falling on it, and the wheat grains will not stay on it.
[0025] Specifically, a first support hole 18 is provided on the first support plate 2, and a first support edge 19 is provided in the first support hole 18. A first outward flange 20 is provided on the upper edge of the equal distribution cylinder 3. The equal distribution cylinder 3 is supported in the first support hole 18 of the first support plate 2 through the first outward flange 20 and the first support edge 19.
[0026] Specifically, a second support plate 21 is provided on the bracket 1 above the first support plate 2. A second support hole 22 is provided on the second support plate 21. A second support edge 23 is provided in the second support hole 22. A second outward flange 24 is provided around the upper edge of the feeding hopper 9. The feeding hopper 9 is supported in the second support hole 22 of the second support plate 21 through the second outward flange 24 and the second support edge 23.
[0027] Specifically, a retaining ring 25 is provided between the inner discharge port 12 and the outer discharge port 13, and the retaining ring 25 is located on the extension line of the outer cylinder side wall. The retaining ring 25 is used to separate the inner discharge port 12 and the outer discharge port 13 to prevent wheat grains falling from the two from mixing with each other.
[0028] Specifically, an inner receiving basket 26 and an outer receiving basket 27 are provided below the equalizing cylinder 3. The inner receiving basket 26 is located below each inner discharge port 12, and its inner and outer diameters are equal in length to the inner and outer diameters of the retaining ring 25. The outer receiving basket 27 is located below each outer discharge port 13. The inner receiving basket 26 is used to receive wheat grains falling from each inner discharge port 12, i.e., to receive the grains; the outer receiving basket 27 is used to receive wheat grains falling from each outer discharge port 13, i.e., to receive the grains. The upper edge of the inner receiving basket 26 is close to but does not contact the lower edge of the retaining ring 25. This prevents wheat grains in the inner receiving basket 26 from splashing out from its upper edge and also makes it easy to place the inner receiving basket 26 below each inner discharge port 12 or remove it from below each inner discharge port 12.
[0029] Specifically, the bottom wall of the outer material basket 27 has a protruding post 28 coaxial with its bottom wall, and the bottom wall of the inner material basket 26 has a groove 29 coaxial with its bottom wall. The inner material basket 26 is placed in the outer material basket 27 through the cooperation of the protruding post 28 and the groove 29. In this way, the inner material basket 26 can be temporarily fixed in the outer material basket 27 so that the inner material basket 26 and the outer material basket 27 are stacked coaxially, and the inner material basket 26 and the outer material basket 27 can be placed under the corresponding discharge ports at the same time, or the inner material basket 26 and the outer material basket 27 can be taken out from under the corresponding discharge ports.
[0030] In use, first, the inner receiving basket 26 and the outer receiving basket 27 are stacked together by the protrusion 28 and the groove 29. Then, the two receiving baskets are placed below the equalizing cylinder 3, so that the upper edge of the inner receiving basket 26 coincides with the lower edge of the retaining ring 25. In this way, the inner receiving basket 26 and the outer receiving basket 27 are respectively placed below each inner discharge port 12 and each outer discharge port 13. Then, the wheat sample to be evenly distributed is added to the feeding hopper 9 from the feeding port 10 using a separately equipped material bucket. The wheat grains in the wheat sample are discharged from the feeding port 13 under the action of gravity. 1. When the wheat sample falls into the dispersing cylinder 3, if there are clumps in the wheat sample, the clumps will be pierced by the spikes 14 on the dispersing component 8. The wheat grains are then evenly dispersed by the dispersing component 8 and fall into the guide trough 7. The bottom of the guide trough 7 is inclined, so the wheat grains will not remain on the inclined surface but will slide along the guide trough 7 towards the inner outlet 12 and the outer outlet 13, respectively, and fall into the inner receiving basket 26 and the outer receiving basket 27. After all the wheat grains have fallen into the inner receiving basket 26 and the outer receiving basket 27, the wheat sample is evenly dispersed. To make the wheat sample more evenly dispersed, the inner receiving basket 26 and the outer receiving basket 27 can be removed from below the dispersing cylinder 3, and all the wheat grains collected in the inner receiving basket 26 and the outer receiving basket 27 can be poured into a material bucket. This dispersing operation can then be repeated several times, such as three to four times, to further disperse the wheat sample evenly.

[0032] In the above embodiments, the discharge port includes an inner discharge port and an outer discharge port. The inner discharge port is the lower port of the guide channel, and the outer discharge port extends outside the side wall of the outer cylinder. This is a preferred technical solution. In other embodiments, both the inner discharge port and the outer discharge port can be set inside the side wall of the outer cylinder, so that the radius of the virtual circle where the outer discharge port is located is larger than the radius of the virtual circle where the inner discharge port is located.
[0033] In the above embodiments, the bulk material component is a cone shape with a smaller top and a larger bottom. In other embodiments, the bulk material component can also be set as a hemispherical shape with a smaller top and a larger bottom.
