Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain samplers, specifically a rapid grain sorting machine. Background Technology
[0002] When sampling and testing products such as grains and oilseeds, multiple sampling points are typically used, followed by multiple sub-sampling of the original samples to obtain a more representative test sample. However, multiple sub-sampling results in a large workload and low efficiency. This is especially true for grain storage enterprises, where multiple "quarter-sampling" methods are time-consuming and labor-intensive when dealing with large quantities of incoming grain or numerous samples requiring testing, significantly impacting operational efficiency. Therefore, improvements are necessary. Summary of the Invention
[0003] The purpose of this invention is to provide a rapid grain sorting machine that can evenly separate the required test samples from the original grain sample in one go, thereby achieving rapid sample sorting and effectively improving the sample testing efficiency.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A rapid grain sorting machine includes an outer shell, which has a feeding hopper, a connecting shell, and an outer hopper connected sequentially from top to bottom. The feeding hopper has an inverted conical structure with a feeding port at the top, and the outer hopper has an inverted conical structure with a non-discharge port at the bottom. The two ends of the connecting shell have connecting ports that respectively connect to the bottom of the feeding hopper and the top of the outer hopper.
[0006] The outer shell contains a separator, which has an inner hopper, a separator pipe, and an inspection discharge pipe. The inner hopper has a conical shell structure with a closed tip. The separator pipe includes at least three pipes, which are evenly distributed along the outer side of the bottom edge of the inner hopper. The top of the separator pipe has an inspection material inlet and is connected to the outer side of the bottom edge of the inner hopper. The inspection discharge pipe includes one pipe located below the separator pipe. The bottom ends of all separator pipes are connected to the inspection discharge pipe.
[0007] The tip of the inner hopper is located near the bottom of the feed hopper and directly opposite the feed inlet of the feed hopper. The bottom of the inner hopper is located near the top of the outer hopper, so that the sizing pipe is arranged inside the outer hopper. The bottom of the inspection discharge pipe extends out from the lower side wall of the outer hopper and has an inspection material outlet. The sizing pipe and the inspection discharge pipe are connected to form an inspection discharge channel.
[0008] In the optimized design, the separator also has a guide cover, which has an inverted conical structure and a closed bottom. The top of the guide cover is connected to the bottom of the inner hopper, and a non-detectable discharge channel is formed between the guide cover and the outer hopper. The non-detectable discharge channel is connected to the non-detectable discharge port of the outer hopper.
[0009] In the optimized design, one side of the inspection material inlet of the skewer is connected to the outer edge of the bottom edge of the inner hopper, and the other side is connected to the inner edge of the top edge of the outer hopper.
[0010] Furthermore, the inner hopper has a conical structure, the outer hopper has an inverted conical structure, and the inspection material inlet of the sampling pipe has a fan-shaped structure, with its inner and outer arc edges respectively connecting to the outer side of the bottom edge of the inner hopper and the inner side of the top edge of the outer hopper.
[0011] In the optimized design, the connecting shell portion of the outer shell has a conical structure, with the tip of the inner hopper located at the center of the top of the connecting shell portion and the bottom end located at the center of the bottom of the connecting shell portion.
[0012] In an optimized version, this utility model also includes a frame, which is connected to the outside of the outer shell and has at least three evenly arranged legs.
[0013] This utility model has the following substantial features and advancements:
[0014] This invention relates to a rapid grain sampling machine. Through the cooperation of the inner hopper and sampling tubes of the sampling unit, the inner hopper disperses and evenly distributes the original sample, while multiple evenly distributed sampling tubes simultaneously perform multi-point uniform sampling of the dispersed sample. This allows for the simultaneous and even extraction of the required test samples from the original grain sample in a single operation. For grain storage enterprises, after the grain vehicle obtains the original sample via an automatic sampler, this rapid grain sampling machine can quickly provide the necessary test samples, significantly improving operational efficiency. Furthermore, this invention features a simple structure, ease of operation, and convenient use. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] Example
[0022] refer to Figures 1 to 5 A rapid grain sorting machine, which includes a shell 1.
[0023] The outer shell 1 has a feed hopper 2, a connecting shell 3 and an outer hopper 4 connected sequentially from top to bottom. The feed hopper 2 has an inverted conical structure with a feed inlet 21 at the top. The outer hopper 4 has an inverted conical structure with a non-discharge outlet 41 at the bottom. The two ends of the connecting shell 3 have connecting ports that respectively connect to the bottom of the feed hopper 2 and the top of the outer hopper 4.
[0024] like Figure 2 and Figure 3 The outer shell 1 is provided with a separator 5. The separator 5 has an inner hopper 6, a separator pipe 7, and an inspection discharge pipe 8. The inner hopper 6 has a conical shell structure with a closed tip 61 at the top. The separator pipe 7 includes at least 3 pipes, which are evenly distributed along the outer side of the bottom edge of the inner hopper 6. The top of the separator pipe 7 has an inspection material inlet 71 and is connected to the outer side of the bottom edge of the inner hopper 6. The inspection discharge pipe 8 includes 1 pipe, which is located below the separator pipe 7. The bottom ends of the separator pipe 7 are all connected to the inspection discharge pipe 8.
[0025] The tip 61 of the inner hopper 6 is located near the bottom of the feed hopper 2 and directly opposite the feed inlet 21 of the feed hopper 2. The bottom of the inner hopper 6 is located near the top of the outer hopper 4, so that the sizing pipe 7 is arranged inside the outer hopper 4. The bottom of the inspection discharge pipe 8 extends out from the lower side wall of the outer hopper 4 and has an inspection material outlet 81. The sizing pipe 7 and the inspection discharge pipe 8 are connected to form an inspection discharge channel.
[0026] The working principle of the above structure is as follows: 1. Feeding: The original grain sample falls into the inner hopper 6 of the separator 5 through the feed inlet 21. 2. Separation: After the original grain sample is dispersed and homogenized by the inverted conical structure of the inner hopper 6, a portion of the original grain sample enters the separation pipe 7 through the test material inlet 71, and flows along the test material outlet channel connected to the test material outlet pipe 8, and is finally discharged from the test material outlet 81, forming a test sample. 3. Discharge: The other portion of the original grain sample does not flow into the test material outlet channel. It falls from the inner hopper 6 into the outer hopper 4 and is discharged as non-test grain from the non-test material outlet 41 of the outer hopper 4.
[0027] In this embodiment, the branch pipe 7 specifically comprises 5 pipes, which are evenly distributed, as follows: Figure 4 and Figure 5 As shown. These five evenly distributed sampling tubes 7 enable uniform sampling of the dispersed and homogenized original sample, thus ensuring that the test sample discharged from the test material outlet 81 meets the requirement of good representativeness.
[0028] Furthermore, the feeder 5 also has a guide cover 9, which has an inverted conical structure and a closed bottom end. The top end of the guide cover 9 is connected to the bottom end of the inner hopper 6. A non-detection discharge channel 91 is formed between the guide cover 9 and the outer hopper 4. The non-detection discharge channel 91 is connected to the non-detection discharge port 41 of the outer hopper 4.
[0029] In the above structure, the guide hood 9 further restricts the space of the grain to be discharged within the outer hopper 4, forming a non-inspection discharge channel 91 to guide the discharge of non-inspection grain, which is then discharged through the non-inspection discharge port 41. This prevents the grain from bouncing and jumping around when it falls onto the inner wall of the outer hopper 4, ensuring rapid discharge of the grain. In addition, the skewer 7 can also be arranged along the outer wall of the guide hood 9, which facilitates the fixing of the skewer 7 and makes the internal structure more compact.
[0030] Furthermore, one side of the inspection material inlet 71 of the sampling pipe 7 is connected to the outer side of the bottom edge of the inner hopper 6, and the other side is connected to the inner side of the top edge of the outer hopper 4, so that the inspection material inlet 71 is connected and arranged close to the inner hopper 6 and the outer hopper 4.
[0031] Furthermore, the inner hopper 6 has a conical structure, the outer hopper 4 has an inverted conical structure, and the inspection material inlet 71 of the sifting pipe 7 has a fan-shaped structure, with its inner and outer arc edges respectively connecting to the outer side of the bottom edge of the inner hopper 6 and the inner side of the top edge of the outer hopper 4.
[0032] In the above structure, an annular channel is formed between the inner hopper 6 and the outer hopper 4. The proportion of the inspection material inlet 71, which has a fan-shaped structure, within this annular channel allows for control of the sample weight. In this embodiment, the five inspection material inlets 71 occupy 1 / 8 of the entire annular channel, evenly distributing 1 / 8 of the original sample each time, while the remaining 7 / 8 falls into the outer hopper 4. This allows for the acquisition of the required inspection sample in one go. In actual operation, the automatic sampler can sample approximately 4000g at a time. After being sampled by the rapid grain sampler in this embodiment, approximately 500g of 1 / 8 of the sample is obtained for inspection purposes, used for grain quality testing.
[0033] Furthermore, the connecting shell portion 3 of the outer shell 1 has a conical structure, with the tip 61 of the inner hopper 6 located at the center of the top of the connecting shell portion 3 and the bottom end located at the center of the bottom of the connecting shell portion 3. The conical structure of the connecting shell portion 3 matches the shape of the inner hopper 6, which also restricts the space above the inner hopper 6 and makes the overall structure more compact.
[0034] Furthermore, such as Figure 2 As shown, it also includes a frame connected to the outside of the housing 1, which has four evenly arranged legs 10.
