Description

Technical Field

[0001] This utility model relates to the field of seed sampling technology, and in particular, to a seed purity detection and sampling device. Background Technology

[0002] Seed purity is a key indicator of seed quality, directly impacting crop yield and quality. Rigorous purity testing is essential throughout seed production, processing, and sales. The first and crucial step in this testing is extracting a representative sample from a large batch of seeds.

[0003] Currently, the most common sampling methods involve using a handheld sampling rod or probe. The operator inserts the sampling rod into the seed bag or container and manually extracts seed samples from a certain depth.

[0004] However, the existing technology has the following drawbacks:

[0005] In existing technologies, in seed sampling, to ensure that the sample accurately reflects the different characteristics of the seeds in the bottom, middle and top layers, it is necessary to obtain seed samples from each layer separately. However, most of the sampling rods currently used adopt an open design. In actual sampling operations, seeds from different layers are easily mixed together as they pass through the inside of the sampling rod or reach the outlet, which damages the original layered structure of the seeds. This not only significantly reduces the sampling accuracy of the sample, but also adversely affects the accuracy of subsequent seed purity testing. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a seed purity detection sampling device that overcomes the defect of layered seed mixing in existing sampling rods, improving sampling accuracy and ease of operation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A seed purity testing sampling device includes a sampling rod:

[0009] A sealing mechanism is installed at one end of the sampling rod to seal the sampling rod, and includes a sealing plate hinged to one end of the sampling rod. A circular baffle is hinged to the inner side of the sealing plate through a rotating shaft. A first reset spring for resetting is fixedly installed between the circular baffle and the sealing plate.

[0010] An adjustment mechanism is installed at the other end of the sampling rod to adjust the sampling space of the sampling rod;

[0011] A discharge mechanism is located on one side of the top of the sampling rod to discharge the seeds inside the sampling rod.

[0012] Furthermore, a movable block is hinged to the bottom of the circular baffle via a pivot, a pull rod is fixedly installed on one side of the movable block, and a pull plate is fixedly installed at the end of the pull rod away from the movable block. The bottom of the pull plate passes through the sampling rod and extends to the bottom of the sampling rod.

[0013] A strip-shaped hole is provided on one side of the bottom of the sampling rod, and the bottom of the pull plate passes through the strip-shaped hole and is slidably connected to it to provide space for the pull plate to move.

[0014] Furthermore, a groove is provided on one side of the bottom of the sampling rod's inner cavity, and the bottom of the movable block passes through the groove and is slidably connected to the groove to provide movement space for the movable block.

[0015] Furthermore, the adjustment mechanism includes a rotating handle rotatably mounted on the surface of the sampling rod via a bearing, and a screw is fixedly mounted on one side of the rotating handle. The screw is installed inside the sampling rod, and a threaded sleeve is threadedly connected to the surface of the screw. An adjustment block is fixedly mounted on the end of the threaded sleeve away from the rotating handle for adjusting the sampling space inside the sampling rod.

[0016] Furthermore, the discharge mechanism includes a strip-shaped discharge port opened on one side of the top of the sampling rod, and an installation cavity is opened inside the sampling rod and on one side of the strip-shaped discharge port. An arc-shaped baffle is slidably installed inside the installation cavity to block the strip-shaped discharge port.

[0017] Several second reset springs are fixedly installed inside the mounting cavity, and one end of each of the second reset springs is fixedly connected to one side of the arc-shaped baffle to reset the arc-shaped baffle.

[0018] Furthermore, a push rod is fixedly installed on the top of the arc-shaped baffle, and two arc-shaped grooves are formed on the surface of the sampling rod on one side of the mounting cavity, with the push rod and the arc-shaped grooves being slidably connected.

[0019] Furthermore, the sampling rod is made of transparent acrylic, and the surface of the sampling rod is provided with scale lines to further improve sampling accuracy.

[0020] Furthermore, a gripping rod is fixedly installed at one end of the sampling rod, and an arc-shaped protrusion for the user to grip is provided on one side of the gripping rod.

[0021] Furthermore, the surface of the rotating handle is provided with a protective sleeve for anti-slip purposes, and the protective sleeve is made of rubber.

[0022] Furthermore, one end of the sampling rod is tapered to facilitate insertion of the sampling rod into the seed storage compartment.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model greatly optimizes the seed sampling process and improves sample accuracy through the setting of a sealing mechanism. Specifically, after the sampling rod is quickly inserted into the inner layer of the seed to be sampled, the pull plate is pulled. The pull plate drives the movable block to slide in the groove through the pull rod, thereby causing the circular baffle to rotate and open the sealing plate. As the sampling rod is continuously inserted, the seed can smoothly enter the interior of the sampling rod. During this process, since the sealing mechanism is in a sealing state during insertion, it effectively avoids the premature mixing of seeds from different layers during insertion, ensuring that the sample can accurately reflect the true characteristics of each layer of seeds, significantly improving the sampling accuracy of the sample, and providing a reliable data basis for subsequent seed purity testing.

[0025] 2. This utility model enhances the adaptability and functionality of the device through the cooperation of the adjustment mechanism, the sealing mechanism, and the discharge mechanism. In the adjustment mechanism, rotating the handle causes the screw to rotate, which in turn moves the threaded sleeve, thereby changing the size of the sampling space inside the sampling rod. After the sealing mechanism is opened, different sizes of sampling spaces can obtain different amounts of seed samples according to actual needs. During discharge, the push rod of the discharge mechanism pushes the arc-shaped baffle to open the strip discharge port, allowing different amounts of seeds to be discharged smoothly. This adjustable design enables the device to adapt to various sampling scenarios and requirements, improving the flexibility and practicality of the device and meeting diverse seed purity testing needs.

[0026] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0039] Please refer to Figures 1 to 5 A preferred embodiment of the seed purity detection sampling device provided by this utility model includes a sampling rod 100:

[0040] A sealing mechanism 200 is installed at one end inside the sampling rod 100 for sealing the sampling rod 100, and includes a sealing plate 210 hinged to one end inside the sampling rod 100. A circular baffle 220 is hinged to the inner side of the sealing plate 210 through a rotating shaft. A first reset spring 230 for resetting is fixedly installed between the circular baffle 220 and the sealing plate 210.

[0041] An adjustment mechanism 300 is installed at the other end of the sampling rod 100 to adjust the sampling space of the sampling rod 100.

[0042] The discharge mechanism 400 is located on one side of the top of the sampling rod 100 to discharge the seeds inside the sampling rod 100.

[0043] Reference Figure 2 As shown, a movable block 240 is hinged to the bottom of the circular baffle 220 via a pivot. A pull rod 250 is fixedly installed on one side of the movable block 240, and a pull plate 260 is fixedly installed at the end of the pull rod 250 away from the movable block 240. The bottom of the pull plate 260 passes through the sampling rod 100 and extends to the bottom of the sampling rod 100. A strip hole is provided on one side of the bottom of the sampling rod 100, and the bottom of the pull plate 260 passes through the strip hole and is slidably connected to it to provide movement space for the pull plate 260.

[0044] In this embodiment, the pull plate 260 slides within the slotted hole, which provides space for the movement of the pull plate 260, thereby enabling the opening and closing of the sealing mechanism 200 to be controlled by the pull plate 260, so as to ensure that the sealing mechanism 200 can work normally.

[0045] Reference Figure 2 As shown, a groove 270 is provided on one side of the bottom of the inner cavity of the sampling rod 100, and the bottom of the movable block 240 passes through the groove 270 and is slidably connected to the groove 270 to provide movement space for the movable block 240.

[0046] In this embodiment, the movable block 240 slides within the groove 270, making it easier for the pull rod 250 to pull the circular baffle 220 to rotate, thus ensuring the normal opening and closing of the sealing mechanism 200.

[0047] Reference Figure 3 as well as Figure 4 As shown, the adjustment mechanism 300 includes a rotating handle 310 rotatably mounted on the surface of the sampling rod 100 via a bearing, and a screw 320 is fixedly mounted on one side of the rotating handle 310. The screw 320 is installed inside the sampling rod 100, and a threaded sleeve 330 is threadedly connected to the surface of the screw 320. An adjustment block 340 is fixedly mounted on the end of the threaded sleeve 330 away from the rotating handle 310 for adjusting the sampling space inside the sampling rod 100.

[0048] In this embodiment, rotating the handle 310 causes the screw 320 to rotate, which in turn moves the threaded sleeve 330. The threaded sleeve 330 then moves the adjusting block 340, thereby changing the size of the sampling space inside the sampling rod 100.

[0049] Reference Figure 5 As shown, the discharge mechanism 400 includes a strip-shaped discharge port opened on one side of the top of the sampling rod 100. An installation cavity 410 is opened inside the sampling rod 100 and on one side of the strip-shaped discharge port. An arc-shaped baffle 420 is slidably installed inside the installation cavity 410 to block the strip-shaped discharge port. A plurality of second return springs 430 are fixedly installed inside the installation cavity 410, and one end of each of the second return springs 430 is fixedly connected to one side of the arc-shaped baffle 420 to reset the arc-shaped baffle 420.

[0050] In this embodiment, the push rod 440 is pushed and slides in the arc-shaped groove 450, which drives the arc-shaped baffle 420 to slide in the mounting cavity 410, compressing the second reset spring 430, opening the strip-shaped discharge port to discharge the seeds, and when the discharge is completed and the push rod 440 is released, the second reset spring 430 resets the arc-shaped baffle 420 to facilitate and quickly discharge the seeds in the sampling rod 100.

[0051] Reference Figure 5 As shown, a push rod 440 is fixedly installed on the top of the arc-shaped baffle 420, and two arc-shaped grooves 450 are opened on the surface of the sampling rod 100 and on one side of the mounting cavity 410. The push rod 440 and the arc-shaped grooves 450 are slidably connected.

[0052] In this embodiment, the push rod 440 slides within the arc-shaped groove 450, providing guidance for the movement of the arc-shaped baffle 420, thereby controlling the opening and closing of the strip discharge port to ensure the stability and accuracy of the operation of the discharge mechanism 400.

[0053] Reference Figure 1 As shown, the sampling rod 100 is made of transparent acrylic and has scale lines 500 on its surface to further improve sampling accuracy.

[0054] In this embodiment, the transparent acrylic sampling rod 100 allows the operator to easily observe the internal sampling situation, while the scale line 500 helps the operator to accurately control the sampling depth and sample volume, thereby further improving the sampling accuracy and making the sampling operation more accurate.

[0055] Reference Figure 1 as well as Figure 3 As shown, a gripping rod 600 is fixedly installed at one end of the sampling rod 100, and an arc-shaped protrusion for the user to grip is provided on one side of the gripping rod 600.

[0056] Reference Figure 3 As shown, the surface of the rotating handle 310 is provided with a protective sleeve for anti-slip purposes, and the protective sleeve is made of rubber.

[0057] In this embodiment, the rubber sheath increases the friction on the surface of the rotating handle 310, making it less likely for the operator to slip when rotating the handle 310.

[0058] Reference Figure 1 As shown, one end of the sampling rod 100 is tapered for inserting the sampling rod 100 into the seed storage compartment;

[0059] In this embodiment, when inserted into the seed storage chamber, the seed layer can be penetrated more easily, thereby reducing the difficulty of inserting the sampling rod 100 into the seed storage chamber.

[0060] Working principle: When in use, firstly, according to the actual sampling requirements, rotate the rotating handle 310 of the adjusting mechanism 300, and the screw 320 will rotate accordingly. The threaded sleeve 330 moves on the screw 320, which drives the adjusting block 340 to move, thereby adjusting the size of the sampling space inside the sampling rod 100.

[0061] Next, holding the handle 600, the cone-shaped sampling rod 100 is quickly inserted into the inner layer of the seed to be sampled. At this time, the sealing plate 210 and the circular baffle 220 of the sealing mechanism 200 are in a sealing state to prevent seeds of different layers from mixing during the insertion process. When the sampling rod 100 reaches the appropriate depth, the pull plate 260 is pulled. The pull plate 260 drives the movable block 240 to slide in the slide groove 270 through the pull rod 250, so that the circular baffle 220 rotates to open the sealing plate 210. As the sampling rod 100 continues to be inserted, the seed enters the sampling space inside the sampling rod 100.

[0062] After sampling is completed, the sampling rod 100 is removed from the seed storage bin. When discharge is required, the push rod 440 of the discharge mechanism 400 is pushed so that it slides in the arc groove 450, which drives the arc baffle 420 to slide in the mounting cavity 410, compresses the second reset spring 430, opens the strip discharge port, and the seeds are discharged from the strip discharge port.

[0063] Furthermore, throughout the process, the scale lines 500 on the surface of the sampling rod 100 can help operators to more accurately control the sampling depth and sampling volume.

[0064] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
