Description

Technical Field

[0001] This utility model relates to the field of collection device technology, specifically a plant disease sample collection device. Background Technology

[0002] In the research and prevention of plant diseases, it is often necessary to collect and prepare specimens. Plant disease specimens can reflect the specific situation of the plant suffering from the disease. At the same time, preserving the specimens well is also convenient for identification and further research. During the collection of plant specimens, the collected plant specimens are usually stored in storage boxes for preservation.

[0003] Traditional devices may use simple slots or binding methods to fix the sampling tube, which are prone to shaking and collisions during transportation, resulting in sample spillage or container damage. Furthermore, the sampling, cutting, and sealing steps require multiple tools, making the operation cumbersome and increasing the risk of tools being forgotten or adding to the burden of carrying them during field operations.

[0004] To address this issue, we propose a plant disease sample collection device. Utility Model Content

[0005] The purpose of this invention is to provide a plant disease sample collection device to solve the problems of unstable sampling tube fixation and low multi-functional integration mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plant disease sample collection device, including a storage box, a door hinged to the front of the storage box, a handle fixedly connected to the top of the storage box, a base fixedly connected to the bottom of the storage box, and a ventilation storage mechanism provided inside the storage box, the ventilation storage mechanism including a ventilation unit and a suspension unit;

[0007] The ventilation unit includes ventilation holes, a filter screen, a circular groove, a fan, mounting bases, and a ventilation mesh plate. The ventilation holes are located on the upper sides of both sides of the storage box. The filter screen is located inside the ventilation holes. The circular groove is located on the bottom surface inside the storage box. The fan is installed inside the circular groove. The mounting bases are fixedly connected to the inner walls of the storage box in two groups of two. The ventilation mesh plate is slidably connected at both ends between the two mounting bases.

[0008] Preferably, the suspension unit includes a placement frame, a limiting rod, a spring, a movable plate, a clamping block, and a partition plate. The placement frame is fixedly connected to both ends of the inner wall of the storage box. A groove is formed on the front of the placement frame, and the limiting rod is disposed within the groove. The partition plate divides the interior of the groove into multiple independent spaces. Springs are respectively fitted onto the outer sides of the limiting rods. Two movable plates are movably connected to each independent space. The clamping block is fixedly connected to the front of the movable plate, and a sampling tube is clamped in the middle of the clamping block. The partition plate divides the groove into multiple independent spaces, allowing multiple sampling tubes to be stored simultaneously, preventing sample mixing. Furthermore, the springs cooperate with the movable plate, causing the clamping block to clamp the sampling tube using elastic force.

[0009] Preferably, the suspension unit consists of three sets, each housed inside the storage box. These three sets of suspension units can store more sampling tubes in layers or areas, meeting the needs of large-scale sampling, and are particularly suitable for collection tasks involving multiple locations and multiple samples.

[0010] Preferably, the sampling tube consists of a left half-tube and a right half-tube, which are connected by a rotating shaft via a connecting rod. An annular block is fixedly connected to the outer sides of both the left and right half-tubes. A rotating seat is fixedly connected to the upper and lower surfaces of the right half-tube, and a sealing cap is rotatably connected to the rotating seat. A cutting blade is provided on the outer side of the sealing cap, and a locking block is fixedly connected to the front end of the sealing cap. The locking block has a locking hole in its center and a locking structure. The left and right half-tubes are connected by the rotating shaft, allowing for quick opening and closing, facilitating the placement of plant disease samples into the tube. This is particularly suitable for collecting irregularly shaped diseased tissues. The sealing cap of the right half-tube is fixed by the rotating seat, and the locking structure ensures a tight seal, preventing the sample from becoming damp, contaminated, or evaporating during transportation, thus maintaining the original state of the diseased sample. The cutting blade on the outer side of the sealing cap can be used directly to trim the diseased sample, eliminating the need for additional scissors and simplifying the sampling process.

[0011] Preferably, the locking structure includes a movable rod, a second spring, and a fixed block. The fixed block is fixedly connected to the upper and lower surfaces of the left half-cylinder. The movable rod is movably connected to the fixed block via the second spring, and the bottom of the movable rod is locked inside the locking hole. The second spring provides elastic force, causing the movable rod to automatically lock into the locking hole, ensuring the sealing cover is securely closed. Pressing the movable rod releases the locking mechanism; the operation is simple and efficient, and can be completed with one hand.

[0012] Preferably, a fixing seat is fixedly connected to the other side of the left and right half-cylinders. A magnetic block is provided on the side of the fixing seat that is close to each other, and the magnetic poles of the magnetic blocks are opposite. The opposite magnetic poles of the magnetic blocks generate an attraction force, so that the left and right half-cylinders are automatically aligned and initially fixed when closed. The auxiliary rotating shaft and the snap-fit ​​structure form a double lock, which enhances the overall sealing performance.

[0013] Preferably, the clamping block engages in a slot composed of two sets of annular blocks. The slot formed by the annular blocks matches the shape of the clamping block, ensuring that the sampling tube is suspended vertically without wobbling, and preventing the sample from tilting or spilling out inside the tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This plant disease sample collection device has a suspension unit that divides the groove into independent spaces through a partition plate. Combined with a spring-loaded elastic clamping block, it can store multiple samples simultaneously and avoid confusion. The limiting rod restricts the movement direction of the movable plate to ensure that the sampling tube is suspended vertically. Combined with the precise matching of the slot and the ring block, it reduces sample shaking or collision during transportation and protects the original morphology of the disease sample.

[0016] 2. This plant disease sample collection device features an integrated cutting blade on the outside of the sampling tube's sealed cap, allowing for direct trimming of diseased samples without the need for additional scissors, making it particularly suitable for rapid field sampling. The left and right halves of the tube open and close via a pivot, automatically aligning with magnetic attraction, allowing for sample placement and closure operations to be completed with just one hand, resulting in higher efficiency than traditional split-type sampling containers.

Two sets of mounting bases 301 are fixedly connected to the inner walls of the storage box 1 in pairs. The ventilation mesh plate 302 is slidably connected at both ends between the two mounting bases 301. This provides an airflow channel, working with the fan 106 to achieve internal air circulation and prevent the samples from deteriorating due to heat and humidity. When the fan 106 operates, it propels airflow, accelerating the exchange of air between the ventilation holes 103 and the internal air, enhancing ventilation and heat dissipation, and maintaining a dry storage environment for the samples.

[0029] The suspension unit includes a placement frame 4, a limiting rod 401, a spring 402, a movable plate 403, a clamping block 404, and a partition plate 405. The placement frame 4 is fixedly connected to both ends of the inner wall of the storage box 1. A groove is formed on the front of the placement frame 4, and the limiting rod 401 is placed in the groove. The partition plate 405 divides the inside of the groove into multiple independent spaces. Springs 402 are respectively fitted onto the outside of the limiting rods 401. Two movable plates 403 are movably connected to each independent space. The clamping block 404 is fixedly connected to the front of the movable plate 403, and a sampling cylinder 5 is clamped in the middle of the clamping block 404. The clamping block 404 is clamped in a slot composed of two sets of annular blocks 503. Three suspension units are respectively installed inside the storage box 1. Springs 402 provide elastic support, causing the movable plate 403 to drive the clamping block 404 to automatically clamp the sampling cylinder 5.

[0030] Example 2:

[0031] Based on Embodiment 1, the sampling cylinder 5 consists of a left half-cylinder and a right half-cylinder. The left and right half-cylinders are connected by a rotating shaft 501 via a connecting rod 502. An annular block 503 is fixedly connected to the outer side of the left and right half-cylinders. A rotating seat 504 is fixedly connected to the upper and lower surfaces of the right half-cylinder. A sealing cover 505 is rotatably connected to the rotating seat 504. A cutting blade 506 is provided on the outer side of the sealing cover 505. The opening and closing design facilitates the loading of plant disease samples.

The movable rod 601 is movably connected to the fixing block 603 via the second spring 602, and the bottom of the movable rod 601 is snapped into the snap-fit ​​hole. A fixing seat 507 is fixedly connected to the other side of the left and right half-cylinders. A magnetic block 508 is provided on the side of the fixing seat 507 that is close to each other, with opposite magnetic poles. The magnetic attraction of the magnetic block 508 tightly closes the left and right half-cylinders, enhancing the overall sealing of the sampling cylinder 5.

[0032] Working principle: Open storage box 1, take out sampling tube 5, open the left and right halves of the tube via rotating shaft 501, and place the diseased sample inside the sampling tube. Alternatively, use the cutting disc 506 on the sealing cap to cut the plant diseased area; the cut sample will fall into sampling tube 5, closing the left and right halves of the tube. Magnetic block 508 automatically attracts and initially closes the left and right halves of the tube; rotate sealing cap 505 to cover the sampling tube opening, and movable rod 601, under the action of spring 602, inserts into the locking hole of locking block 509, locking sealing cap 505.

[0033] Place the sampling tube 5 between the clamping blocks 404 of the suspension unit. Spring 402 automatically pushes the clamping blocks 404 to lock the annular block 503, fixing the sampling tube 5. Close the box door 101 and turn on the fan 106 to maintain internal air circulation and prevent the samples from deteriorating. Lift the storage box by the handle 2. The base 102 provides stable support, and the elastic clamping of the suspension unit reduces the shaking of the sampling tube during transportation.
