Description

Technical Field

[0001] The utility model relates to the field of grain storage equipment and facilities, in particular to a sampler for preventing grain from being broken. Background Art

[0002] The storage of grain is an important part of ensuring grain safety and quality. In order to detect the quality of grain stored in granaries, a device called a sampler (or sampler) is usually used for sampling. The sampler is connected to the granary through a pipe system and uses the principle of vacuum negative pressure to extract grain from the warehouse for inspection.

[0003] During the operation, due to the effect of vacuum negative pressure, the grain particles are quickly sucked through the pipe and enter the collecting cylinder of the sampler. During this high-speed movement process, the grain particles collide with the inner wall of the sampler multiple times. Especially when the grain moisture content is low and the hardness is high, these collisions may cause the grain particles to break or break, thereby affecting the representativeness of the sample and subsequent test results. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a sampler for preventing grain from being broken.

[0005] The technical solution of this utility model is as follows:

[0006] A sampler for preventing grains from being broken comprises a sampler body, wherein the sampler body comprises a main cylinder body, and a buffer mechanism capable of providing a buffering effect for grains is arranged on the inner cylinder wall of the main cylinder body.

[0007] As the core technical concept of the utility model, the buffer mechanism includes a hair tube arranged on the inner wall of the main cylinder body, and a mesh tube arranged on the inner circle of the hair tube, the hair tube includes soft hair whose inner circle points to the mesh tube, and there is a gap between the root of the soft hair and the outer circle of the mesh tube, the mesh tube is densely covered with mesh holes, and the outer ends of the soft hair are arranged to pass through the mesh holes. Through the buffer mechanism set up in this sampler, when the grains are drawn into the main cylinder body, they will not directly hit the hard wall of the main cylinder body, but will first contact the outer ends of the soft hairs. As the grains fall, the soft hairs effectively absorb and disperse the impact force of the grains, thereby gently guiding the grains to fall into the main cylinder body under the action of their own gravity. This design greatly reduces the breakage of grains due to impact during the sampling process, thereby ensuring that the collected grain samples have high integrity, providing a reliable basis for subsequent detection and analysis.

[0008] It should be noted that the principle and structure of the sampler for sucking grains are similar to those of existing grain samplers, so they will not be introduced in detail here.

[0009] As described above, a sampler for preventing grain from being crushed is, as a preferred embodiment, the hair tube also includes a convex strip arranged on its outer ring, and a groove matching with the convex strip is vertically provided on the inner wall of the main cylinder body, and the hair tube can be plugged and connected with the groove of the main cylinder body through the convex strip. This arrangement facilitates disassembly and assembly and improves disassembly and assembly efficiency.

[0010] In order to prevent the hair tube from moving down along the main cylinder, a stopper capable of supporting the hair tube is provided at the inner circle of the lower end of the main cylinder wall to maintain the stable position of the buffer mechanism, ensure the consistency of the buffer effect, and extend the service life of the sampler.

[0011] As described above, a sampler for preventing grain from being crushed, the mesh tube includes a plurality of arc-shaped mesh plates with arc-shaped cross-sections, and the sides of two adjacent arc-shaped mesh plates are in contact, the hair tube also includes a plurality of arc-shaped plates corresponding to the arc-shaped mesh plates one by one, and the convex strips and soft hairs are respectively arranged on the outer side and the inner side of the arc-shaped plates to prevent grains from falling into the gap between the two arc-shaped mesh plates, making it difficult to take out. This arrangement improves the convenience of operation.

[0012] As a preferred embodiment, the two sides of the arc plate extend inward, and the two sides of the arc mesh plate are plugged and connected to the extended parts. During use, since the outer layer of the grain carries fine dust, dust is easily accumulated on the outer ends of the soft hair and the arc mesh plate after a period of use. This arrangement facilitates the disassembly of the arc mesh plate. The arc mesh plate can be removed from the inside of the main cylinder to clean the dust. At the same time, when the arc mesh plate is removed, the mesh holes will scrape off the dust on the soft hair. In addition, when the arc mesh plate is plugged in, the outer ends of the soft hair will bend downward. This arrangement can also facilitate installation by shaking the arc mesh plate up and down to allow the soft hair to pass through the mesh holes.

[0013] Furthermore, the material of the curved mesh plate is PVC soft board. In some special cases, the impact of the grains increases. At this time, the grains may pass through the soft hair and hit the curved mesh plate. By setting the curved mesh plate PVC soft board material, the impact of the grains is mitigated, the integrity of the grains is protected more comprehensively, and the accuracy of grain sample inspection is further improved.

[0014] As a further preferred embodiment, the thickness of the curved mesh plate is not less than 5 mm, ensuring that the curved mesh plate has sufficient strength and durability to provide long-term reliable use and reduce maintenance costs.

[0015] Furthermore, the aperture of the mesh is 0.4mm-0.6mm. The sampler is commonly used for sampling wheat and rice. The average length of wheat grains is between 2-3 mm and the width is about 0.8-1.2 mm. The average length of rice grains is between 4-5 mm and the width is about 2-3 mm. Therefore, setting the aperture of the mesh to 0.4mm-0.6mm is more appropriate, which can prevent grains from passing through the mesh and maximize the amount of soft hair that can pass through the mesh.

[0016] In order to minimize grain breakage, the length of the outer end of the soft hair passing through the mesh is set to 5mm-10mm, ensuring that the soft hair has sufficient strength and can more effectively absorb the impact energy of the grain, minimize grain breakage, and maintain the integrity of the grain sample.

[0017] The beneficial effect of the sampler for preventing grain from breaking of the utility model is that: through the buffer mechanism, when the grains are drawn into the main cylinder, they will not directly hit the hard wall of the main cylinder, but will first contact the outer end of the soft hair. As the grains fall, the soft hair effectively absorbs and disperses the impact force of the grains, so that under the action of the grains' own gravity, they are gently guided to fall into the main cylinder. This design greatly reduces the breakage of grains due to impact during the sampling process, thereby ensuring that the collected grain samples have high integrity, providing a reliable basis for subsequent testing and analysis. In addition, in some special cases, when the impact force of the grains is large, the grains may pass through the soft hair and hit the curved mesh plate. The setting of the PVC soft plate material of the curved mesh plate slows down the impact of the grains, protects the integrity of the grains in a more comprehensive way, and further improves the accuracy of subsequent grain sample inspections.

[0025] Combination Figure 1 and Figure 2 The present embodiment provides a sampler for preventing grain from being broken, including a sampler body 1. The sampler body 1 includes a main cylinder 11. A buffer mechanism 2 capable of providing a buffering effect for grains is provided on the inner cylinder wall of the main cylinder 11. After the grains enter the main cylinder 11 through the buffer mechanism 2, they collide with the buffer mechanism 2, and after the force is unloaded by the buffer mechanism 2, they can fall into the main cylinder 11 under the action of their own gravity. The grains are not easy to be broken, thereby improving the accuracy of subsequent grain sample detection. The structure of the buffer mechanism 2 is described in detail below.

[0026] Combination Figure 3 The buffer mechanism 2 includes a hair tube arranged on the inner wall of the main cylinder body 11, and a mesh tube arranged on the inner circle of the hair tube. The mesh tube includes a plurality of arc-shaped mesh plates 22 with arc-shaped cross-sections. The hair tube includes a plurality of arc-shaped plates 21 corresponding to the arc-shaped mesh plates 22. Preferably, the number of the arc-shaped mesh plates 22 and the number of the arc-shaped plates 21 are both 4, and the included angles are both 90 degrees.

[0027] Combination Figure 4 The inner circle of the lower end of the main cylinder 11 is provided with a stopper 12 capable of supporting four arc-shaped plates 21 to prevent the hair cylinder from moving down along the main cylinder 11, maintain the stable position of the buffer mechanism 2, ensure the consistency of the buffer effect, and extend the service life of the sampler.

[0028] As the core technical feature of the utility model, the inner circle of the hair tube is densely covered with soft hair 23 pointing to the mesh tube, the roots of the soft hair 23 have a gap with the outer circle of the mesh tube, the mesh tube is densely covered with mesh holes, and the outer ends of the soft hair 23 pass through the mesh holes. When the grains are drawn into the main cylinder 11, they will not directly hit the hard wall of the main cylinder 11, but will first contact the outer ends of the soft hair 23. As the grains fall, the soft hair 23 effectively absorbs and disperses the impact force of the grains, thereby gently guiding the grains to fall into the main cylinder 11 under the action of their own gravity. This design greatly reduces the breakage of grains due to impact during the sampling process, thereby ensuring that the collected grain samples have high integrity, providing a reliable basis for subsequent detection and analysis.

[0029] Combination Figure 3 The length of the outer end of the soft hair 23 passing through the mesh is set to 5mm-10mm, which ensures that the soft hair 23 has sufficient strength and can more effectively absorb the impact energy of the grain, minimize the breakage of the grain, and maintain the integrity of the grain sample.

[0030] In this embodiment, the aperture of the mesh is 0.4mm-0.6mm. The sampler is commonly used for sampling wheat and rice. The average length of wheat grains is between 2-3 mm and the width is approximately 0.8-1.2 mm. The average length of rice grains is between 4-5 mm and the width is approximately 2-3 mm. Therefore, setting the aperture of the mesh to 0.4mm-0.6mm is more appropriate, which can prevent grains from passing through the mesh and maximize the soft hair 23 to pass through the mesh.

[0031] For the structure of the curved mesh plate 22, combined with Figure 3 Specifically:

[0032] The sides of two adjacent arc-shaped mesh plates 22 are in contact with each other to prevent grains from falling into the gap between the two arc-shaped mesh plates 22, which makes it difficult to take out. This arrangement improves the convenience of operation.

[0033] The material of the curved mesh plate 22 is PVC soft board. In some special cases, the impact of the grains increases. At this time, the grains may pass through the soft hair 23 and hit the curved mesh plate 22. The setting of the curved mesh plate 22 PVC soft board material can reduce the impact of the grains, protect the integrity of the grains in a more comprehensive way, and further improve the accuracy of grain sample inspection.

[0034] The thickness of the curved mesh plate 22 is not less than 5 mm, which ensures that the curved mesh plate 22 has sufficient strength and durability to provide long-term reliable use and reduce maintenance costs.

[0035] For the structure of the curved plate 21, combined Figure 3 Specifically, a convex strip is vertically provided in the middle of the outer circle of the four arc plates 21, and a groove matching the convex strip is vertically provided on the inner wall of the main cylinder body 11. The four arc plates 21 can be plugged into the groove of the main cylinder body 11 through the convex strip. This arrangement facilitates disassembly and assembly, and improves the disassembly and assembly efficiency of the four arc plates 21.

[0036] The two sides of the arc plate 21 extend inward, and a groove is vertically provided in the middle of the extended part. The two sides of the arc mesh plate 22 are provided with convex strips plugged into the grooves. During use, since the outer layer of the grain carries fine dust, dust is easily accumulated on the outer end of the soft hair 23 and the arc mesh plate 22 after a period of use. This arrangement facilitates the disassembly of the arc mesh plate 22. The arc mesh plate 22 can be removed and taken out from the inside of the main cylinder 11 for dust cleaning. At the same time, when the arc mesh plate 22 is removed, the mesh will scrape off the dust on the soft hair 23. In addition, when the arc mesh plate 22 is plugged in, the outer end of the soft hair 23 will bend downward. This arrangement can also facilitate installation. The arc mesh plate 22 can be shaken up and down to make the soft hair 23 pass through the mesh, thereby improving the utilization rate of the soft hair 23.

[0037] The utility model discloses a sampler for preventing grain from being broken. By means of the buffer mechanism 2, when the grains are drawn into the main cylinder 11, they will not directly hit the hard wall of the main cylinder 11, but will first contact the outer end of the soft hair 23. As the grains fall, the soft hair 23 effectively absorbs and disperses the impact force of the grains, thereby gently guiding the grains to fall into the main cylinder 11 under the action of their own gravity. This design greatly reduces the breakage of the grains due to impact during the sampling process, thereby ensuring that the collected grain samples have high integrity, providing a reliable basis for subsequent detection and analysis. In addition, in some special cases, when the impact force of the grains is large, the grains may pass through the soft hair 23 and hit the arc-shaped mesh plate 22. By setting the arc-shaped mesh plate 22 PVC soft plate material, the impact of the grains is mitigated, the integrity of the grains is more comprehensively protected, and the accuracy of subsequent grain sample inspection is further improved.
