Description

Technical Field

[0001] This utility model relates to the field of soybean quarantine, specifically to a portable soybean field quarantine sampler. Background Technology

[0002] With the increasing frequency of soybean planting and trade, field quarantine of soybeans is of paramount importance, as it relates to soybean quality and safety, pest and disease control, and the stability of the agricultural ecosystem. To ensure healthy soybean growth and prevent the spread of harmful organisms, scientific and effective quarantine sampling of soybeans in the field is necessary.

[0003] Currently, existing soybean field sampling methods mainly have the following problems:

[0004] Existing technologies typically involve manual sampling. Traditional manual sampling requires staff to bend over or squat down and directly grab soybean samples from soybean plants or soil with their hands. This process is cumbersome, time-consuming, and physically demanding, resulting in low sampling efficiency and making it difficult to meet the needs of large-scale field quarantine work.

[0005] Furthermore, traditional methods can easily cause mechanical damage to soybean plants during the sampling process, such as breaking stems or damaging the root system. This can not only affect the normal growth and development of soybean plants, but may also lead to the spread of pests and diseases, which can have an adverse effect on soybean yield and quality.

[0006] Therefore, we have made improvements to this by proposing a portable soybean field quarantine sampler. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a portable soybean field quarantine sampler, which solves the problems mentioned in the background art.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A portable soybean field quarantine sampler was developed to address the aforementioned issues.

[0010] The application is as follows:

[0013] As a preferred technical solution of this application, a limiting rod is fixedly installed on one side surface of the fixing plate, and a first limiting groove is opened on the surface of the telescopic rod, and the limiting rod and the first limiting groove are connected by a sliding connection.

[0014] As a preferred technical solution of this application, the cutting mechanism includes a groove, which is opened in the middle of the fixed box. A stop block and a cutter are slidably connected to both sides of the groove. A connecting block is fixedly installed on one side surface of the stop block, and a rack is fixedly installed on one side surface of both the connecting block and the cutter. A gear is rotatably connected inside the fixed box, and the gear is located between two racks, and both racks are meshed with the gear.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] 1. By using the adjustment mechanism, the motor drives the threaded rod to rotate, which, in conjunction with the threaded groove on the telescopic rod, allows the telescopic rod to extend and retract smoothly within the fixed cylinder, thus easily changing the height of the sampling cylinder. This allows quarantine personnel to quickly and accurately adjust the sampling position according to the actual growth height of the soybean plants without bending over or squatting, greatly improving sampling efficiency, reducing labor intensity, and effectively enhancing overall work efficiency.

[0021] 2. By using the cutting mechanism, the hydraulic rod drives the cutter, and through the meshing transmission of gears and racks, the cutter and the stop move synchronously in opposite directions, quickly cutting the soybean plants in the sampling tube. This ensures the integrity and accuracy of the sample. Compared with the traditional manual sampling method, the cutting mechanism effectively reduces mechanical damage to the soybean plants, lowers the risk of disease and pest transmission, ensures the normal growth and development of the soybean plants, and also improves the sampling quality, providing a reliable basis for subsequent quarantine work.

[0034] To address the technical problems in the background section, the following portable soybean field quarantine sampler is provided:

[0035] Combination Figure 1 - Figure 5 As shown, this utility model provides a portable soybean field quarantine sampler, including a fixed cylinder 1, a telescopic rod 2 slidably connected inside the fixed cylinder 1, and an adjustment mechanism 3 between the telescopic rod 2 and the fixed cylinder 1. A sampling cylinder 4 is fixedly installed at one end of the telescopic rod 2, and a fixed box 5 is fixedly installed at the lower end of the sampling cylinder 4. The fixed box 5 is connected to the sampling cylinder 4, and a cutting mechanism 6 is provided inside the fixed box 5. The adjustment mechanism 3 includes a fixed plate 301, which is fixedly installed inside the fixed cylinder 1. A threaded rod 302 is fixedly installed on one side surface of the fixed plate 301, and a threaded groove 303 is opened in the middle of the telescopic rod 2. The threaded rod 302 is threadedly connected to the threaded groove 303. A motor 304 is fixedly installed on the other side surface of the fixed plate 301, and the output end of the motor 304 is fixedly connected to one end of the threaded rod 302.

[0036] In this embodiment, the telescopic rod 2, which is slidably connected inside the fixed cylinder 1, can adjust the height of the sampling cylinder 4 through the adjustment mechanism 3. This allows for flexible adjustment based on the different heights of the soybean plants, ensuring the accuracy and rationality of the sampling position. In the adjustment mechanism 3, a fixed plate 301 is installed inside the fixed cylinder 1. A motor 304 drives a threaded rod 302 to rotate, which engages with a threaded groove 303 in the middle of the telescopic rod 2, enabling the telescopic rod 2 to extend and retract smoothly within the fixed cylinder 1, greatly improving the flexibility and convenience of the sampling operation. The sampling cylinder 4 is fixedly installed at one end of the telescopic rod 2, and its lower end is tightly connected to the fixed box 5. The cutting mechanism 6 inside the fixed box 5 can cut the sample after it is encased, ensuring the integrity and independence of the sample and providing a reliable basis for subsequent quarantine analysis.

[0037] In a preferred embodiment, a limiting rod 305 is fixedly installed on one side surface of the fixing plate 301, and a first limiting groove 306 is provided on the surface of the telescopic rod 2, and the limiting rod 305 and the first limiting groove 306 are connected by a sliding connection.

[0038] In this embodiment, the telescopic movement of the telescopic rod 2 within the fixed cylinder 1 provides stable and precise guidance, effectively preventing the telescopic rod 2 from deviating or swaying during movement, thereby greatly improving the accuracy and stability of sampling.

[0039] In a preferred embodiment, the cutting mechanism 6 includes a groove 601, which is located in the middle of the fixed box 5. A stop block 602 and a cutter 603 are slidably connected to both sides of the groove 601. A connecting block 604 is fixedly installed on one side surface of the stop block 602. A rack 605 is fixedly installed on one side surface of both the connecting block 604 and the cutter 603. A gear 606 is rotatably connected inside the fixed box 5. The gear 606 is located between two racks 605, and both racks 605 are meshed with the gear 606.

[0040] In this embodiment, the stop block 602 and the cutter 603 are located on both sides of the groove 601, respectively. They form a meshing transmission system with the gear 606 inside the fixed box 5 through the connecting block 604 and the rack 605. When the cutter 603 is driven to move, the rack 605 on it drives the gear 606 to rotate. Then, through meshing with the rack 605 on the stop block 602, the stop block 602 and the cutter 603 move synchronously in opposite directions to cut the plants inside and take samples.

[0041] In a preferred embodiment, the two sides of the stop block 602 and the cutter 603 are provided with a second limiting groove 607, and a fixing post 608 is provided inside the second limiting groove 607. The fixing post 608 is fixedly installed inside the fixing box 5, and the fixing post 608 is slidably connected to the second limiting groove 607.

[0042] In this embodiment, the two sides of the stop block 602 and the cutter 603 are provided with second limiting grooves 607, and the fixed box 5 is fixedly installed with a corresponding fixing post 608. The fixing post 608 and the second limiting groove 607 are connected by a sliding connection, which can limit the movement of the stop block 602 and the cutter 603 and prevent them from shifting during movement.

[0043] In a preferred embodiment, a hydraulic rod 609 is fixedly installed on one side surface of the fixing box 5, and a fixing block 610 is fixedly installed on the telescopic end of the hydraulic rod 609. The fixing block 610 is fixedly installed on one side surface of the cutter 603.

[0044] In this embodiment: the telescopic end of the hydraulic rod 609 is fixedly connected to one side surface of the cutter 603 through the fixing block 610. The hydraulic rod 609 can control the movement of the cutter 603, and cooperate with the rack 605 and gear 606 to cut the sample plant.

[0045] In a preferred embodiment, a handle 7 is fixedly installed at one end of the fixed cylinder 1, and a storage battery 8 is fixedly installed inside the handle 7. The storage battery 8 is connected to the motor 304 and the hydraulic rod 609 through wires, and a control switch 9 is fixedly installed on the outer surface of the handle 7.

[0046] In this embodiment, the battery 8 inside the handle 7 is connected to the motor 304 and the hydraulic rod 609 via wires, providing power support for the power components of the entire sampler. The control switch 9 is fixedly installed on the outer surface of the handle 7, which facilitates the control of the operation of the motor 304 and the extension and retraction of the hydraulic rod 609, thereby improving the efficiency and convenience of the sampling work.

[0047] When in use, the operator holds the handle 7 and starts the motor 304 by controlling the switch 9 according to the height of the soybean plant. The motor 304 drives the threaded rod 302 to rotate. Since the threaded rod 302 is threadedly engaged with the threaded groove 303 in the middle of the telescopic rod 2, and the telescopic rod 2 is guided by the sliding of the limiting rod 305 and the first limiting groove 306, the telescopic rod 2 can be smoothly extended and retracted in the fixed cylinder 1, thereby adjusting the sampling cylinder 4 to a suitable height. During sampling, the sampling tube 4 is placed over the target plant. Then, the hydraulic rod 609 is activated via the control switch 9. The telescopic end of the hydraulic rod 609 pushes the cutter 603 through the fixing block 610. The rack 605 on the cutter 603 drives the gear 606 to rotate, which in turn meshes with the rack 605 on the stop block 602, causing the stop block 602 and the cutter 603 to move synchronously in opposite directions. Under the sliding limit of the fixing post 608 and the second limiting groove 607, the cutter 603 precisely cuts the plant, while the stop block 602 closes the sampling channel, ensuring the sample is intact and independent. Throughout the process, the battery 8 provides power to the motor 304 and the hydraulic rod 609, and the control switch 9 enables convenient operation, greatly improving the efficiency, accuracy, and convenience of soybean field quarantine sampling.
