Description

Technical Field

[0001] This utility model relates to the field of grain testing technology, and in particular to a foldable portable grain sampling device. Background Technology

[0002] Grain sampling is a key pretreatment step in grain quality testing (such as moisture, impurities, and bulk density determination). Its core requirement is that the seed samples after sampling must maintain the representativeness of the original samples. The HGG-Ⅱ model horizontal sampler has a simple and practical structure. Through one or more sorting operations, it can obtain one or more equal and uniform seed samples. It is an important tool for improving sampling efficiency in grain and oil inspection. At present, it is being gradually promoted and applied in grain inspection units at all levels and has achieved good results.

[0003] The existing patent, CN216309569U, discloses a high-efficiency grain sampling device, including a conical feed hopper, a shell, a reducing mechanism and at least one mixing mechanism disposed within the shell, with the feed hopper connected to the shell. The reducing mechanism is located directly below the mixing mechanism, which, from top to bottom, includes a turntable, a rotating shaft, a motor, and a frustum-shaped collecting hopper, with the collecting hopper located below the motor. The reducing mechanism includes a conical movable cover plate and upper and lower cones that fit together. The movable cover plate covers the upper cone and is rotatably connected to it via a rotating handle. Multiple matching first and second sampling holes are evenly distributed on the movable cover plate and the upper cone. A discharge hole is located at the bottom of the lower cone, connected to a discharge pipe, with a receiving cylinder located below the discharge pipe. This invention can automatically complete multiple mixing and uniform sample dispensing in one operation, reducing the workload of quality inspectors and improving work efficiency.

[0004] Although the above scheme uses multiple sampling holes, which can automatically complete multiple mixing and uniform sampling at one time and reduce the workload of quality inspectors, the above equipment is too bulky for the large-scale sampling needs of warehouses. It is very inconvenient to transport and assemble, and it is prone to blockage at the feed inlet when there is too much grain to test. It requires staff to make constant adjustments, which consumes a lot of time and energy. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable portable grain sampling device, comprising: a horizontal sampler, characterized in that: two fixed columns are fixedly connected to both sides of the bottom of the horizontal sampler; a telescopic strip is provided at the bottom of each of the fixed columns; a support leg is movably connected to one end of each of the telescopic strips; a sliding groove is provided on the outer surface of each of the support legs; a slider is slidably connected inside each of the sliding grooves; a connecting rod is movably connected to the outer surface of each of the sliders; a limit shaft is movably connected to the other end of each of the connecting rods; a rotating rod is movably connected at the intersection center of the connecting rods; the support legs are divided into two groups on average; a sampling disc is movably connected to the opposite side of each group of support legs.

[0006] The technical effect of adopting the above-mentioned further solution is that the adjacent support legs are pulled apart in opposite directions. At this time, the connecting rod slides inside the sliding groove through the slider, so that the included angle between the connecting rod and the limiting shaft reaches the minimum. Finally, the two adjacent support legs are separated to the maximum extent, and the horizontal sample divider is placed on the top of the telescopic strip through the fixed column, reducing the floor space occupied during use.

[0007] In a preferred embodiment, the top of the horizontal sampler is provided with a sieve.

[0008] The technical advantage of adopting the above-mentioned further solution is that the grain sample obtained by sampling is placed inside the sieve, eliminating the need for manual feeding of grain samples and increasing work efficiency.

[0009] In a preferred embodiment, a fixing plate is fixedly installed on one side of the horizontal sample divider, a motor is provided on the top of the fixing plate, the output shaft of the motor is fixedly connected to a rotating shaft, and an elliptical block is fixedly connected to the top of the rotating shaft.

[0010] The technical effect of adopting the above-mentioned further solution is as follows: when the motor is started, the output shaft of the motor drives the elliptical block to rotate through the rotating shaft. When the elliptical block rotates, it will contact the screen due to its volume and strike one side of the screen. After the screen is struck, the holes inside the screen will vibrate, causing the grain to enter the interior of the horizontal sampler for mixing and sampling.

[0011] In a preferred embodiment, two springs are fixedly connected to one outer surface of the screen, two dampers are fixedly connected to one outer surface of the screen, a fixing block is fixedly connected to the other side of the two dampers, and the other side of the two springs is fixedly connected to one outer surface of the dampers.

[0012] The technical effect of adopting the above-mentioned further solution is that after the screen is hit, it moves to one side, and the spring and damper are compressed by the force of the movement. When the force of the impact disappears, the screen returns to its original position through the rebound of the spring.

[0013] In a preferred embodiment, a material distribution box is fixedly connected to the bottom of the horizontal sample divider.

[0014] The technical effect of adopting the above-mentioned further solution is that the material distribution box is used to distribute samples into the sample distribution tray.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, when adjacent support legs are pulled apart in opposite directions, the connecting rod slides inside the sliding groove via a slider, minimizing the angle between the connecting rod and the limiting shaft. Finally, the two adjacent support legs are separated to their maximum extent, and the horizontal sample divider is placed on top of the telescopic bar via a fixed column, reducing the floor space required for use. A suitable container is prepared at the sample dividing plate to receive the prepared sample, and the mixed sample falls from the sample dividing plate into the container, reducing the labor costs of using the equipment.

[0016] In this invention, the grain sample obtained through sampling is placed inside the sieve. Due to the density of the grain, the openings of the sieve may become clogged. Since the grain needs to be placed flat and slowly during sampling, relying solely on manual labor would reduce work efficiency by several times. At this point, the motor is started, and the motor's output shaft drives the elliptical block to rotate through the rotating shaft. The rotating elliptical block contacts the sieve due to its volume, striking one side of the sieve. After being struck, the openings inside the sieve vibrate, causing the grain to enter the horizontal sampler flat for mixing and sampling. After being struck, the sieve rebounds due to the buffering effect of springs and dampers, so that the sieve always returns to its original position after each strike, thus achieving a reciprocating parallel movement.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figures 1 to 4 This utility model provides a foldable portable grain sampling device, comprising: a horizontal sampler 101, characterized in that: two fixed posts 110 are fixedly connected to both sides of the bottom of the horizontal sampler 101; each of the fixed posts 110 has a telescopic strip 109 at its bottom; one end of each telescopic strip 109 is movably connected to a support leg 102; the outer surface of each support leg 102 has a sliding groove 103; a slider 104 is slidably connected inside each sliding groove 103; the outer surface of each slider 104 is movably connected to a connecting rod 105; and the other end of each connecting rod 105 is movably connected to... The limiting shaft 106 and multiple connecting rods 105 are movably connected to the center of their intersection with rotating rods 107. Multiple support legs 102 are divided into two groups. Each group of support legs 102 is movably connected to a sample tray 108 on the opposite side. When adjacent support legs 102 are pulled apart in opposite directions, the connecting rods 105 slide inside the sliding groove 103 through the slider 104, causing the angle between the connecting rods 105 and the limiting shaft 106 to reach its minimum. Finally, the two adjacent support legs 102 are separated to their maximum extent, and the horizontal sample divider 101 is placed on top of the telescopic strip 109 through the fixed column 110, reducing the floor space occupied during use.

[0022] like Figures 1 to 4 As shown, the top of the horizontal sampler 101 is equipped with a sieve 114. The grain sample obtained by sampling is placed inside the sieve 114, eliminating the need for manual feeding of grain samples and increasing work efficiency.

[0023] like Figures 1 to 4As shown, a fixing plate 111 is fixedly installed on one side of the horizontal sampler 101. A motor 119 is installed on the top of the fixing plate 111. The output shaft of the motor 119 is fixedly connected to a rotating shaft 112. An elliptical block 113 is fixedly connected to the top of the rotating shaft 112. When the motor 119 is started, the output shaft of the motor 119 drives the elliptical block 113 to rotate through the rotating shaft 112. When the elliptical block 113 rotates, it will come into contact with the screen 114 due to its volume, thereby striking one side of the screen 114. After the screen 114 is struck, the holes inside it will vibrate, causing the grain to enter the interior of the horizontal sampler 101 evenly for mixing and sampling.

[0024] like Figures 1 to 4 As shown, two springs 115 are fixedly connected to one outer surface of the screen 114, and two dampers 118 are fixedly connected to one outer surface of the screen 114. A fixing block 116 is fixedly connected to the other side of the two dampers 118. The other side of the two springs 115 is fixedly connected to one outer surface of the dampers 118. When the screen 114 is hit, it moves to one side. The springs 115 and dampers 118 are compressed by the force of the movement. When the force of the impact disappears, the screen 114 returns to its original position through the rebound of the springs 115.

[0025] like Figures 1 to 4 As shown, a material distribution box 117 is fixedly connected to the bottom of the horizontal sample divider 101. The material distribution box 117 is used to distribute samples into the interior of the sample distribution tray 108.

[0026] The working principle of this utility model is as follows: Adjacent support legs 102 are pulled apart in opposite directions. At this time, the connecting rod 105 slides inside the sliding groove 103 via the slider 104, minimizing the angle between the connecting rod 105 and the limiting shaft 106. Finally, the two adjacent support legs 102 are separated to their maximum extent. The horizontal sampler 101 is then placed on top of the telescopic bar 109 via the fixed column 110, reducing the floor space required for use. The grain sample obtained from sampling is placed inside the sieve 114. Due to the density of the grain, the openings of the sieve 114 may become clogged. Since the grain needs to be laid flat and slowly during sampling, relying solely on manual labor would reduce work efficiency by several times. Therefore, the motor 119 is started. The output shaft of the motor 119 drives the ellipse via the rotating shaft 112. The elliptical block 113 rotates, and its volume contacts the screen 114, striking one side of the screen 114. After being struck, the internal openings of the screen 114 vibrate, causing the grain to enter the horizontal sampler 101 smoothly for mixing. The screen 114 rebounds after being struck by the spring 115 and the damper 118, causing it to return to its original position each time it is struck, thus achieving a reciprocating parallel movement. The grain will continuously and smoothly enter the horizontal sampler 101 for mixing without manual operation. A suitable container is prepared at the sampling tray 108 to receive the prepared sample. The mixed sample falls from the sampling tray 108 into the container, reducing the labor cost of using the equipment.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
