Description

Technical Field

[0001] This utility model relates to the field of agricultural testing equipment technology, specifically to a mechanized sampling device for rapidly assessing the growth quality of potatoes, and in particular a potato rapid testing sampler that achieves efficient visual detection and component analysis through standardized segmentation. Background Technology

[0002] In the pre-harvest quality assessment of potatoes, traditional testing methods mainly rely on manual sampling and cutting, which has the following significant drawbacks:

[0003] 1. Low efficiency and lack of standardization: When potatoes are cut manually with knives, the processing time for a single sample can be as long as 5-10 minutes. Furthermore, the flatness of the cut surface and the uniformity of the size of the strip samples heavily depend on the operator's experience, resulting in poor sample comparability and failing to meet the rapid testing needs of large-scale planting.

[0004] 2. Deficiency in sample representativeness: Existing manual cutting usually only takes a local area of ​​the potato (such as the middle of the tuber), which is difficult to fully reflect the overall internal condition. When there are local hollows, rot, or uneven nutrient distribution, it is easy to cause misjudgment.

[0005] 3. Operational safety risks: When repeatedly cutting hard potatoes with a hand-held knife, the operator's hand is easily injured due to slippage, and incomplete disinfection of the knife may cause cross-contamination of samples.

[0006] The aforementioned defects severely restrict the accuracy and timeliness of potato harvest timing judgment; although some automated equipment has attempted to improve this, its complex structure, inconvenient movement, and inability to flexibly adjust sample specifications according to testing needs make it difficult to apply quickly in the field. Utility Model Content

[0007] To overcome the shortcomings of low efficiency, poor sample representativeness, and high operational risks associated with manual potato cutting, this invention provides a standardized and rapid field testing tool. This tool utilizes a synergistic cutting structure of through-holes in the grid plate and protrusions in the nail plate, along with a spring reset mechanism, to achieve standardized and rapid potato segmentation, significantly improving testing efficiency and operational safety.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: a potato rapid testing sampler includes a base, which is L-shaped and has an internal cavity. One end of the base is a potato inlet, and the other end is used to discharge the cut potato strips. The base has symmetrical grooves on both sides. A grid plate is vertically and detachably installed at one end inside the base. The grid plate is formed by a uniform grid structure of interlaced thin plates, and the upper part of the grid plate has several through holes. A nail plate is vertically installed inside the base and opposite to the grid plate. One side of the nail plate has an outward protrusion corresponding to the position of the through hole. A toggle assembly includes a plate base, a locking plate, a handle, a connecting rod, a slider, and a spring. The plate base abuts against the back of the nail plate. The back of the nail plate has a hook that penetrates the plate base. The locking plate is hinged to the back of the plate base and its two ends are engaged with the hook. Two U-shaped sliders are hinged to both sides of the plate base and embedded in the grooves of the base. The handle is hinged to one end of the base, and the two ends of the connecting rod are respectively hinged to the handle and the slider. The two ends of the spring are respectively connected to the base and the plate base to realize the nail plate reset.

[0009] In the aforementioned potato rapid testing sampler, the through hole is shaped as a square, a circle, or a polygon.

[0010] In the aforementioned potato rapid testing sampler, the protrusions on the nail plate are sharp cone-shaped or wedge-shaped.

[0011] The aforementioned potato rapid testing sampler has protruding nails penetrating the plate base around the back of the nail plate.

[0012] In the aforementioned potato rapid testing sampler, the surface of the chute is a smooth plane, and its size matches that of the slider.

[0013] In the aforementioned potato rapid testing sampler, the spring is a tension spring, which connects the machine base and the plate base via a hook.

[0014] The aforementioned potato rapid testing sampler has an obtuse angle structure on one side of the handle.

[0015] The beneficial effects of this utility model are:

[0016] 1. Standardized Slicing: The uniform grid of the grating plate and the raised spikes across the entire area of ​​the nail plate work together to ensure that the potatoes are evenly divided, eliminating the deviation of manual sampling;

[0017] 2. Increased operational efficiency: Mechanical linkage cutting replaces manual cutting, significantly reducing the processing time for a single sample;

[0018] 3. Safety and hygiene: The spring automatically resets to prevent contact with the blade, and the detachable design facilitates thorough disinfection, eliminating the risk of cross-contamination. Attached Figure Description

[0027] In agricultural production, quickly and accurately determining the growth status of potatoes and whether they meet harvest requirements is crucial. This embodiment of the potato rapid sampling device aims to provide an efficient and convenient tool for rapid sampling and segmentation of potatoes. This allows workers to make accurate judgments by observing the visual appearance of the segmented potato strips or further analyzing their nutritional components. Figure 1-6 As shown, the sampler mainly includes key components such as base 1, grid plate 2, nail plate 3, and actuation assembly 4. All components work together to complete the rapid sampling task of potatoes.

[0028] The base 1, serving as the fundamental support structure of the entire sampler, is L-shaped with a spacious internal cavity. This design not only provides ample space for potato placement and cutting but also makes the entire sampler structure more compact and rational. One end of the base 1 is designed as the potato inlet, allowing staff to easily place the potatoes to be tested inside; the other end is used to discharge the cut potato strips for subsequent observation and analysis. The base 1 has symmetrically arranged, meticulously designed grooves 11. The surface of the grooves 11 is finely machined to be smooth and flat, reducing friction on the slider 45 during sliding. The size and shape of the grooves 11 match the slider 45, ensuring stable and smooth linear reciprocating sliding of the slider 45, providing reliable assurance for the stable movement of the actuating component 4. Furthermore, the base 1 is made of high-strength engineering plastics or metal materials, possessing excellent wear resistance and impact resistance, capable of withstanding various external forces during long-term use, thus ensuring the sampler's service life.

[0029] The grating plate 2 is one of the key components for potato cutting. It can be vertically installed and detached at one end inside the base 1. This detachable design has many advantages. On the one hand, it facilitates the installation of the appropriate grating plate 2 according to different testing requirements before the sampler is used. On the other hand, it can be easily disassembled for cleaning and disinfection after use, preventing cross-contamination between different batches of potatoes and ensuring the accuracy of test results. The grating plate 2 is made of interlaced thin plates. The thin plates are usually made of stainless steel or food-grade plastic, which have good strength and corrosion resistance. Through precise calculation and design, the interlaced thin plates form... The uniform grid structure creates several through holes evenly distributed on the upper part of the grid plate 2. The shape and size of the through holes can be customized according to actual testing requirements, such as common square, circular, or polygonal shapes. Different through hole shapes and sizes will divide the potato strips into different specifications to meet diverse testing needs. For example, for experiments that require testing the internal structure of potatoes, larger through holes can be selected to obtain thicker potato strips, making it easier to observe their internal details; while for studies that require testing the distribution of potato nutrients, smaller through holes can be selected to obtain finer potato strips, improving the accuracy of the test.

[0030] The nail plate 3 is vertically arranged inside the base 1 and faces the grid plate 2. One side of the nail plate 3 has protrusions 31 that are evenly spaced and correspond to the positions of the through holes. These protrusions 31 are the key parts for effectively dividing potatoes. The shape of the protrusions 31 is usually designed as a sharp cone or wedge, which can apply greater pressure to the potatoes when they cooperate with the grid plate 2, making them easier to divide into strips. The number and distribution of the protrusions 31 correspond one-to-one with the through holes on the grid plate 2, ensuring that each protrusion 31 can be accurately inserted into the corresponding through hole when the nail plate 3 pushes the potatoes forward, so as to divide the potatoes evenly. The nail plate 3 is made of high-hardness alloy steel or specially treated engineering plastic to ensure that the protrusions 31 will not wear or deform during long-term use and will always maintain good dividing performance. At the same time, the surface of the nail plate 3 is polished, smooth and flat, reducing the friction between it and the potatoes and making the pushing process smoother.

[0031] The actuating assembly 4 is the core component driving the nail plate 3 to perform linear reciprocating motion. Its design rationality and stability directly affect the overall working effect of the sampler. The actuating assembly 4 mainly includes a base 41, a locking plate 42, a handle 43, a connecting rod 44, a slider 45, and a spring 46. These components cooperate to complete the driving task of the nail plate 3. The back of the nail plate 3 is fitted with a base 41, which supports and fixes the nail plate 3, while also providing a foundation for the installation of other components. A hook 32 extends outward from the back of the nail plate 3, penetrating the base 41. The hook 32 is designed with a certain degree of elasticity and strength to firmly hold the base 41. A locking plate 42 is hinged to the center of the back of the base 41. Both ends of the locking plate 42 extend outward and engage with the hook 32. When needed... When fixing the nail plate 3 to the plate base 41, simply rotate the locking plate 42 to engage with the hook 32 to achieve a secure connection. When it is necessary to disassemble the nail plate 3, simply rotate the locking plate 42 to the unlocked position to easily remove the nail plate 3. This connection method combining the hook 32 and the locking plate 42 is simple and convenient to operate, and the connection is firm and reliable. In order to further improve the accuracy of the connection between the nail plate 3 and the plate base 41 and prevent relative displacement during movement, protruding nails 33 penetrating the plate base 41 are arranged around the back of the nail plate 3. The number and position of the protruding nails 33 are carefully designed to be evenly distributed around the back of the nail plate 3 and fit tightly with the holes on the plate base 41 to ensure that the nail plate 3 and the plate base 41 will not move relative to each other in any direction, thereby ensuring the stability and accuracy of the dividing process.

[0032] U-shaped sliders 45 are hinged to both sides of the base 41. The design of the sliders 45 matches the slide grooves 11 on both sides of the base 1. The U-shaped structure allows the sliders 45 to connect better with the base 41, while reducing the contact area with the slide grooves 11 and reducing friction. The sliders 45 are embedded in the slide grooves 11 on both sides of the base 1 and can slide linearly back and forth in the slide grooves 11. During the sliding process, the gap between the sliders 45 and the slide grooves 11 is reasonably designed to ensure smooth sliding and prevent the sliders 45 from shaking in the slide grooves 11, thus ensuring the stability of the movement of the actuating component 4. A handle 43 that can rotate around one end of the base 1 is hinged to one end. The handle 43 is the part that the operator directly applies power to. The design of the handle 43... The handle is ergonomically designed with a suitable length and thickness for easy gripping and rotation. A connecting rod 44 is arranged between the handle 43 and the slider 45, with both ends of the connecting rod 44 hinged to the handle 43 and the slider 45 respectively. This hinged connection allows the connecting rod 44 to flexibly transmit power when the handle 43 is rotated, driving the slider 45 to reciprocate within the slide groove 11. One side of the handle 43 has an obtuse angle structure. This design is to meet the traction operation of the slider 45. When the handle 43 is rotated, the obtuse angle structure allows the connecting rod 44 to maintain a suitable angle during movement, avoiding jamming or obstructed movement, and ensuring that power can be effectively transmitted to the slider 45, thereby driving the nail plate 3 to move stably.

[0033] To ensure the nail plate 3 automatically resets after potato cutting for subsequent potato cutting, a tension spring 46 is attached between the machine base 1 and the plate base 41. The spring 46 is made of high-quality, high-elasticity steel wire, possessing excellent elasticity and fatigue resistance. Both ends of the spring 46 are connected to the machine base 1 and the plate base 41 via hooks, ensuring a secure and reliable connection. When the handle 43 rotates, driving the nail plate 3 forward to cut potatoes, the spring 46 is stretched, storing elastic potential energy. After cutting, releasing the handle 43 releases the spring force, pulling the plate base 41 and nail plate 3 back to their initial positions, achieving automatic reset of the nail plate 3. This spring 46 reset design significantly improves the sampler's efficiency, reduces the operator's workload, and makes continuous potato cutting and testing possible.

[0034] Working Process: Select a suitable grating plate 2 according to the testing requirements and install it inside one end of the machine base 1. Check that all components of the sampler are securely installed, ensure that the actuating component 4 moves smoothly and the spring 46 has normal elasticity. Then, place the potato to be tested inside the machine base 1 near the handle 43, ensuring that the potato is placed stably and in the correct position. The operator then holds the handle 43 and slowly rotates it. The handle 43 drives the slider 45 to slide forward in the slide groove 11 through the connecting rod 44. The slider 45 then drives the plate base 41 and the nail plate 3 to move forward. The protrusions 31 on the nail plate 3 push the potato along the inside of the machine base 1 towards the grating plate 2. When the potato reaches the grating plate 2, the protrusions 31 and the grating plate 2 apply pressure to the potato, causing it to be cut into strips. The cut potato strips are discharged through the through holes on the grating plate 2 and fall into the pre-prepared collection container. The operator observes the discharged potato strips. The visual appearance of the fries, such as color, texture, and uniformity, can provide a quick assessment of the potato's growth. For example, if the fries are uniformly colored and firm, it indicates that the potatoes are growing well and may meet harvest requirements. If the fries show discoloration, rot, or loose texture, it indicates that the potatoes may have growth problems and require further inspection or delayed harvesting. If necessary, testing instruments can be used to further analyze the nutritional components of the fries. For example, a near-infrared spectroscopy analyzer can quickly detect the content of nutrients such as starch, protein, and vitamins in the fries, providing more accurate data support for potato quality assessment. After completing one cutting test, the handle 43 is released, and the nail plate 3 automatically returns to its initial position under the elastic force of the spring 46. At this time, the next potato to be tested can be placed, and the above operation process can be repeated to achieve continuous rapid potato sampling.

[0035] The potato rapid testing sampler of this embodiment has a simple structure and is easy to operate. It can quickly and accurately sample and divide potatoes for testing, providing an effective tool for potato harvesting and quality assessment, and has broad application prospects.
