Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a sampling device for detecting pathogens of diseases during ginger storage. Background Technology

[0002] Ginger is susceptible to various pathogens during storage, leading to diseases such as rot and affecting its quality and shelf life. Detection of pathogens causing ginger diseases during storage is a crucial step in controlling disease spread and ensuring the safety of ginger after harvest. Sampling, as the initial step in testing, directly impacts the accuracy of subsequent pathogen isolation and identification results due to its standardized operation.

[0003] Chinese patent CN119043798B discloses a ginger root sampling device for root disease research. This device includes a base and a mounting platform above the base. A limiting plate is fixed to the side of the mounting platform away from the base, and a second limiting plate slides on the mounting platform. The first limiting plate has an opening, and a cutting blade is located on the side of the first limiting plate near the second limiting plate. A clamp for fixing the ginger root is provided on the mounting platform, and a sample collection assembly is provided on the base. This invention allows for rapid sampling of ginger roots, is convenient to use, has high safety performance, and allows for adaptive adjustment of the sampling device. It can sample different locations on the ginger root, thus facilitating research on ginger root diseases by growers and offering high work efficiency.

[0004] The ginger root sampling device used for root disease research mainly focuses on juice extraction and collection after sampling, without mentioning a structure for slicing the sample. This makes it difficult to directly obtain thin slice samples that can be used for pathogen detection from ginger during storage, requiring additional tools for subsequent processing. In view of this, we propose a sampling device for detecting pathogens of ginger during storage. Utility Model Content

[0005] The purpose of this invention is to provide a sampling device for detecting pathogens of diseases during ginger storage, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sampling device for detecting pathogens causing diseases during ginger storage includes a sampling platform with a top seat above it. A guide sleeve is fixed to the top of the top seat, and a sampling component is fitted inside the guide sleeve. The sampling component includes a cutting sleeve fitted inside the guide sleeve and moving vertically along the guide sleeve, a push rod fitted inside the cutting sleeve and movable along the axial direction of the cutting sleeve, and a second spring fitted outside the cutting sleeve. The cutting sleeve has a hollow cylindrical structure, with an end post installed at the top of the cutting sleeve. A pair of levers are fixed on the outer circumferential surface of the end post. The bottom end of the push rod extends into the cutting sleeve and is fitted with a push plate. The top end of the second spring abuts against the levers. A slicing component is provided at the rear of the sampling component. The slicing component includes a movable frame and a fixed seat located above the movable frame. Several parallel blades are embedded in the movable frame, and several abutment plates are fixed to the bottom of the fixed seat. The positions of the abutment plates correspond to the gaps formed by two adjacent blades.

[0007] Preferably, the rear end of the sampling stage is connected to the rear end of the top seat by a connecting arm, which has an L-shaped rod structure. In this setup, the L-shaped connecting arm securely connects the sampling stage and the top mount, providing stable support for the top mount and the components above, ensuring structural stability during the sampling and slicing process.

[0008] Preferably, the guide sleeve has a hollow cylindrical structure, and the top seat has a through hole that communicates with the inside of the guide sleeve. The bottom end of the cutting sleeve extends downward from the through hole. A pair of waist-shaped grooves are formed on the outer peripheral surface of the guide sleeve along its axial direction, and the two levers extend outward from the two waist-shaped grooves respectively. In this configuration, the hollow cylindrical guide sleeve provides a vertical movement track for the cutting sleeve, the through hole provides space for the cutting sleeve to move, and the waist-shaped groove limits the range of motion of the lever to ensure the stability of the cutting sleeve's movement direction.

[0009] Preferably, the end post is sleeved inside the guide sleeve, the bottom end of the end post is provided with a protrusion, and the top end of the cutting sleeve is sleeved on the outside of the protrusion and fixedly connected to the protrusion. In this setup, the cooperation between the end post and the guide sleeve helps stabilize the movement of the cutting sleeve, while the fixed connection between the protruding post and the cutting sleeve ensures that the two move synchronously, improving the continuity of the sampling action.

[0010] Preferably, the top of the push rod is T-shaped, the bottom of the push rod vertically penetrates the end post and is slidably connected to the end post, and a first spring is sleeved on the outside of the push rod; In this setup, the T-shaped top makes it easy for the operator to apply force to press the push rod, the sliding connection between the push rod and the end post ensures smooth axial movement, and the first spring can drive the push rod to automatically reset, facilitating subsequent sampling.

[0011] Preferably, the movable frame has a hollow rectangular frame structure, and sliding rods are fixed at both the front and rear ends of the movable frame. The top end of the sliding rod passes through the connecting arm and is slidably connected to the connecting arm. The top end of the sliding rod is T-shaped, and a third spring is sleeved on the outside of the sliding rod located above the connecting arm. In this setup, the hollow rectangular frame provides installation space for the blade, the sliding engagement of the sliding rod and the connecting arm ensures the vertical stability of the frame, the T-shaped top prevents the sliding rod from falling off, and the third spring can drive the frame to reset.

[0012] Preferably, a lever is fixed on both the left and right end surfaces of the movable frame, and the lever is used to move the movable frame along the sliding rod; In this setup, the lever provides the operator with a point of leverage, making it easier to move the movable frame along the sliding rod by flicking it, thus making the slicing operation more convenient.

[0013] Preferably, the fixed base is fixed to the bottom end of the connecting arm. When no external force is applied, the third spring, under the action of elastic force, drives the movable frame to approach the fixed base through the sliding rod. In this setup, the fixed base provides a foundation for the support plate, and the elasticity of the third spring keeps the movable frame close to the fixed base, facilitating slicing operations at any time and improving ease of use.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This ginger storage pathogen detection and sampling device integrates sampling and slicing functions through its sampling and slicing components. After the sampling component obtains the ginger sample, the slicing component can directly cut the sample into thin slices using multiple parallel blades. The thin slices can be used directly for pathogen detection without the need for additional tools for subsequent slicing, thus improving the continuity of sampling and detection.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figures 1-3 A sampling device for detecting pathogens causing diseases during ginger storage includes a sampling platform 100 made of stainless steel for placing ginger samples. A top seat 110 is positioned above the sampling platform 100. The rear end of the sampling platform 100 is connected to the rear end of the top seat 110 via a connecting arm 111. The connecting arm 111 is an L-shaped rod made of stainless steel, providing stable support for the top seat 110 and ensuring the rigidity of the overall structure. A guide sleeve 120 is fixed to the top of the top seat 110. The guide sleeve 120 is a hollow cylindrical structure made of wear-resistant alloy to reduce wear during internal component movement. A through hole communicating with the interior of the guide sleeve 120 provides a channel for the movement of the sampling component 200. A pair of waist-shaped grooves 121 are formed along the axial direction on the outer circumferential surface of the guide sleeve 120. The waist-shaped grooves 121 limit the range of motion of the lever 2112, ensuring the stability of the vertical movement of the cutting sleeve 210.

[0018] A sampling component 200 is provided in the guide sleeve 120. The sampling component 200 includes a cutting sleeve 210 that is sleeved in the guide sleeve 120 and moves vertically along the guide sleeve 120, a push rod 220 that is sleeved in the cutting sleeve 210 and can move along the axial direction of the cutting sleeve 210, and a second spring 230 that is sleeved on the outside of the cutting sleeve 210. The second spring 230 is made of high elasticity spring steel and can provide reset power after the cutting sleeve 210 moves down.

[0019] The cutting sleeve 210 has a hollow cylindrical structure and is made of high-strength alloy steel. Its bottom end is shaped like a circular blade, which can easily cut into the ginger tissue to complete the sampling. The bottom end of the cutting sleeve 210 extends downward from the through hole on the top seat 110, and the two levers 2112 extend outward from the two waist-shaped grooves 121 respectively, making it easy for the operator to hold and apply force.

[0020] The top of the cutting sleeve 210 is equipped with an end post 211. The end post 211 is made of aluminum alloy, which is lightweight and has suitable strength. The end post 211 is fitted inside the guide sleeve 120. A pair of levers 2112 are fixed on the outer circumferential surface of the end post 211. The bottom end of the push rod 220 extends into the cutting sleeve 210 and is equipped with a push plate 221. The push plate 221 is made of food-grade silicone, which can not only fit tightly against the inner wall of the cutting sleeve 210, but also avoid contamination of the sample. The top of the second spring 230 abuts against the levers 2112. The bottom end of the end post 211 is provided with a protrusion 2111. The protrusion 2111 is integrally formed with the end post 211. The top of the cutting sleeve 210 is fitted on the outside of the protrusion 2111 and is fixedly connected to the protrusion 2111. This connection method can ensure that the cutting sleeve 210 and the end post 211 move synchronously.

[0021] The top of the push rod 220 is T-shaped and made of stainless steel, making it easy for operators to press. The bottom of the push rod 220 vertically passes through the end post 211 and is slidably connected to the end post 211. A first spring 222 is sleeved on the outside of the push rod 220. The first spring 222 is also made of spring steel and can drive the push rod 220 to return to its original position after it is pressed.

[0022] When using the ginger storage pathogen detection sampling device of this embodiment, firstly, place the ginger to be sampled on the sampling platform 100 to determine the sampling position; then, press down the lever 2112 to drive the cutting sleeve 210 to move vertically downward along the guide sleeve 120, and the blade-like structure at the bottom of the cutting sleeve 210 cuts into the ginger tissue, while the second spring 230 is compressed; next, after sampling is completed, release the lever 2112, and the second spring 230 pushes the lever 2112 and the cutting sleeve 210 upward to reset under the action of elastic force; finally, press down the push rod 220, and the push rod 220 drives the push plate 221 to move downward along the axial direction of the cutting sleeve 210 to push out the ginger sample in the cutting sleeve 210, and then release the push rod 220, and the first spring 222 drives the push rod 222 and the push plate 221 to reset.

[0023] Example 2 To slice the cylindrical ginger core after sampling component 200, such as... Figure 1 and Figure 4As shown, a slicing assembly 300 is provided on the rear side of the sampling assembly 200. The slicing assembly 300 includes a movable frame 310 and a fixed seat 320 located above the movable frame 310. The movable frame 310 is made of high-strength stainless steel and has several parallel blades 311 embedded inside. The blades 311 are made of sharp stainless steel and can cut the ginger sample into uniform thin slices. Several abutments 321 are fixed at the bottom of the fixed seat 320. The abutments 321 are made of rubber and their positions correspond to the gaps formed by two adjacent blades 311. Their function is to extend into the gaps between adjacent blades 311 when the movable frame 310 slices the ginger through the blades 311 and then returns to its original position, so that the ginger slices stuck in them are pushed out and prevented from getting stuck in the gaps between adjacent blades 311.

[0024] The movable frame 310 has a hollow rectangular frame structure. Sliding rods 312 are fixed at both the front and rear ends of the movable frame 310. The sliding rods 312 are made of smooth stainless steel to reduce frictional resistance during movement. Their top ends pass through and slide along the connecting arm 111. The top of the sliding rod 312 is T-shaped to prevent it from falling off the connecting arm 111. A third spring 313, made of highly elastic spring steel, is fitted on the outer side of the sliding rod 312 above the connecting arm 111 to drive the movable frame 310 to its original position. A lever 314, made of stainless steel, is fixed to the left and right ends of the movable frame 310 for easy operation and to move the movable frame 310 along the sliding rods 312.

[0025] The fixing seat 320 is fixed to the bottom end of the connecting arm 111. It is made of aluminum alloy and has a stable structure. When there is no external force, the third spring 313 drives the movable frame 310 to approach the fixing seat 320 through the sliding rod 312 under the action of elastic force, so that the blade 311 and the abutment plate 321 are in a corresponding state, which prepares for slicing and subsequent ejection of the slice.

[0026] In this embodiment, the sampling device for detecting pathogens during ginger storage is used by first placing the cylindrical ginger core taken out by the sampling component 200 directly on the surface of the sampling stage 100 below the movable frame 310. At this time, the abutment plate 321 and the movable frame 310 are relatively close. Then, the dial plate 314 is pushed down, causing the movable frame 310 to move downward along the sliding rod 312. The blade 311 moves with the movable frame 310 to slice the ginger core placed on the surface of the sampling stage 100. At the same time, the third spring 313 is compressed. After slicing, the dial plate 314 is released, and the third spring 313 drives the movable frame 310 to return to its original position. At this time, the abutment plate 321 extends into the gap between the adjacent blades 311, pushing out the ginger slice stuck in the gap to prevent the ginger slice from getting stuck in the gap. At this time, a thin sample can be taken out from the sampling stage 100 for pathogen detection.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
