Description

Technical Field

[0001] This utility model relates to the field of grain sampling technology, specifically a novel single-tube sampler. Background Technology

[0002] In the grain and seed industries, accurate sampling is crucial for quality testing and evaluation. To accurately determine seed quality, purity, germination rate, and other indicators, samplers are used to test grains and seeds, allowing for the selection of seeds that meet quality standards. This prevents substandard seeds from entering the market, ensures smooth agricultural production, and reduces losses for farmers due to seed quality issues.

[0003] For example, the layered sampling mechanism of a grain seed sampler disclosed in Chinese Utility Model Patent Publication No. CN219573593U, through the design of the control mechanism, allows seeds to enter through three sampling holes after the insertion rod is inserted into the grain pile during sampling. These three sampling holes can respectively sample seeds at the end, middle, and nearest ends, achieving the purpose of layered sampling. Simultaneously, to ensure rapid seed entry into the sampling holes, the up-and-down movement of the push rod is controlled to accelerate seed entry and avoid... Shaking the insertion rod to accelerate seed entry may damage the outer packaging bag. However, in actual use, the sampling hole lacks a closed structure, causing seeds to spill during sample removal. Furthermore, after the seeds are removed, they need to be taken out of the sampling hole and sent to the testing equipment for analysis. This process is cumbersome and inefficient when testing many batches of seeds. Therefore, a new type of single-tube sampler is needed to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a novel single-tube sampler, which solves the problems mentioned in the background art, such as the seeds easily scattering during the sampler removal process and the need for specialized testing equipment during detection, resulting in cumbersome overall operation and reduced efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel single-tube sampler, comprising a sampler body, a bag-breaking component threadedly installed at the front end of the sampler body, a detection component provided at the rear side of the sampler body, a gripping component threadedly installed at the rear end of the detection component, a rotating component provided at the front side of the detection component, a charger provided at the front end of the detection component, an arc-shaped groove opened on the inner side of the sampler body, an arc-shaped plate provided on the inner side of the arc-shaped groove, a rod sensor provided at the middle of the front end of the detection component, and a sleeve provided on the inner side of the rotating component.

[0009] Optionally, the bag-breaking assembly includes a pointed block, a spiral sleeve, and a diamond-shaped groove. The spiral sleeve is provided at the rear end of the pointed block, and the diamond-shaped groove is provided on the outer side of the front end of the pointed block.

[0010] Optionally, the detection component includes a moisture detector body, a control button, a display screen, and a grounding block. The control button is located on the rear side of the upper end of the moisture detector body, the display screen is located on the front side of the control button, and the grounding block is located at the front end of the moisture detector body.

[0011] Optionally, the grip assembly includes a grip handle, an inner groove, a battery compartment, and a battery. The inner groove is provided on the inner side of the front end of the grip handle, and the battery compartment is provided inside the inner groove. The battery compartment is embedded with a battery.

[0012] Optionally, the rotating assembly includes a rotating block, a gripping rod, a soft sleeve, and a hollow tube. The gripping rod is provided above the outer end of the rotating block, and the soft sleeve is sleeved on the outer end of the gripping rod.

[0014] Optionally, the pointed block and the sleeve are integrated into one piece, and an internal threaded groove is provided on the inner side of the rear end of the sleeve, with four diamond-shaped grooves symmetrically distributed.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model has a reasonable structure. With the arc-shaped groove and arc-shaped plate, when conducting seed testing, the sampler body is quickly inserted into the grain bag through the pointed block, allowing the seeds in the bag to enter the storage tanks at different positions from front to back. Then, the operator holds the gripping rod to drive the rotating block to rotate counterclockwise, thereby causing the arc-shaped plate to move clockwise from the arc-shaped groove of the lower rod body to the arc-shaped groove inside the upper rod body, closing the upper end of the storage tank. Afterwards, when the sampler body is pulled out, it is ensured that the seeds in the storage tank will not spill out.

[0017] 2. In this utility model, the moisture detector body is activated by the control button after the sampler body is inserted into the grain bag and the seeds fall into the storage trough. This powers the insertion rod sensor, allowing it to contact the seed to be tested. Since the moisture in the seed affects the electrical parameters of the insertion rod sensor, the electrical parameters are observed on the display screen, thus achieving moisture measurement. By combining the sampler body, insertion rod sensor, and moisture detector body, seeds can be detected directly within the sampler body. Compared to traditional methods that require specialized equipment for grain seed testing, this method is more convenient and efficient.

[0018] 3. In this utility model, the design of the lower rod and the upper rod, which are spliced ​​together, makes the sampler body a detachable structure. Compared with the traditional one-piece design, it is more convenient to clean the internal groove in the later stage, and avoids too many impurities remaining in the groove, which will affect the subsequent testing of grain seeds.

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.

[0026] Example: Reference Figures 1-5 The novel single-tube sampler shown includes a sampler body 1, a bag-breaking component 2 threadedly mounted at the front end of the sampler body 1, a detection component 3 located at the rear of the sampler body 1, a gripping component 4 threadedly mounted at the rear end of the detection component 3, a rotating component 5 located at the front of the detection component 3, and a charger 6 located at the front end of the detection component 3. The charger 6 is magnetically attached to the front end of the detection component 3 for easy and quick use. An arc-shaped groove 7 is symmetrically distributed inside the lower rod 101 and upper rod 102 of the sampler body 1. Furthermore, the two arc-shaped grooves 7 opened inside the lower rod body 101 and the upper rod body 102 can form a circular structure. An arc-shaped plate 8 is provided on the inner side of the arc-shaped groove 7. The arc-shaped plate 8 can rotate inside the arc-shaped groove 7. An insertion rod sensor 9 is provided in the middle of the front end of the detection component 3. The insertion rod sensor 9 and the moisture detector body 301 are electrically connected. Moreover, the insertion rod sensor 9 is the core component of the existing moisture detector body 301. Both are existing known technologies. Therefore, they have not been described in detail in this application. A sleeve 10 is provided on the inner side of the rotating component 5. The sleeve 10 is made of insulating material.

[0027] The sampler body 1 includes a lower rod 101, an upper rod 102, a front thread 103, a rear thread 104, a storage trough 105, and a mounting hole 106. The upper rod 102 is located above the lower rod 101. The lower rod 101 and the upper rod 102 are identical in size, length, and diameter. The front ends of the lower rod 101 and the upper rod 102 are provided with front threads 103, and the rear ends of the lower rod 101 and the upper rod 102 are provided with rear threads 104. Storage troughs 105 are laterally formed on the inner sides of the lower rod 101 and the upper rod 102. Five storage troughs 105 are arranged in an array. A mounting hole 106 is formed in the middle of the upper end of each storage trough 105. The mounting hole 106 consists of two semi-circular slots, symmetrically distributed at the middle of the upper end of the lower rod 101 and the upper rod 102. The lower middle part of 02; the bag breaking assembly 2 includes a pointed block 201, a spiral sleeve 202 and a diamond groove 203. The spiral sleeve 202 is provided at the rear end of the pointed block 201. The pointed block 201 and the spiral sleeve 202 are integrated. The inner side of the rear end of the spiral sleeve 202 is provided with an internal thread groove, which is convenient for installation with the front thread 103 of the lower rod 101 and the upper rod 102. The outer side of the front end of the pointed block 201 is provided with a diamond groove 203. There are four diamond grooves 203 symmetrically distributed to facilitate breaking the outer skin of the grain bag; the rotating assembly 5 includes a rotating block 501, a gripping rod 502, a soft sleeve 503 and a hollow tube 504. The gripping rod 502 is provided above the outer end of the rotating block 501. The soft sleeve 503 is sleeved on the outer end of the gripping rod 502. The hollow tube 504 is provided at the rear end of the rotating block 501.

[0028] With the arc-shaped groove 7 and arc-shaped plate 8 in place, during seed testing, the sampler body 1 is quickly inserted into the grain bag via the pointed block 201, allowing the seeds in the bag to enter the storage troughs 105 at different positions from front to back. Then, the operator holds the gripping rod 502 and drives the rotating block 501 to rotate counterclockwise, thereby causing the arc-shaped plate 8 to move clockwise from the arc-shaped groove 7 of the lower rod 101 to the arc-shaped groove 7 inside the upper rod 102, closing the upper end of the storage trough 105. Afterwards, when the sampler body 1 is pulled out, it is ensured that the seeds in the storage trough 105 will not spill out.

[0029] The design of the lower rod 101 and upper rod 102, which are connected together, makes the sampler body 1 a detachable structure. Compared with the traditional one-piece design, it is more convenient to clean the internal groove later, and avoids too many impurities remaining in the groove, which would affect the subsequent testing of grain seeds.

[0030] like Figures 1 to 4As shown, in this embodiment, the detection component 3 includes a moisture detector body 301, a control button 302, a display screen 303, and a power contact block 304. The control button 302 is located on the rear side of the upper end of the moisture detector body 301, and the display screen 303 is located on the front side of the control button 302. The power contact block 304 is located at the front end of the moisture detector body 301. The grip component 4 includes a grip handle 401, an embedded groove 402, a battery compartment 403, and a battery 404. The embedded groove 402 is opened on the inner side of the front end of the grip handle 401, and the battery compartment 403 is located inside the embedded groove 402. The battery 404 is embedded and installed inside the battery compartment 403.

[0031] When the sampler body 1 is inserted into the grain bag and the seeds fall into the storage trough 105, the moisture detector body 301 is turned on by the control button 302. The battery 404 supplies power to the insertion rod sensor 9, allowing the insertion rod sensor 9 to contact the seeds to be tested. Since the moisture in the seeds affects the electrical parameters of the insertion rod sensor 9, the electrical parameters of the insertion rod sensor 9 can be observed through the display screen 303, thereby realizing the moisture measurement. By combining the sampler body 1, the insertion rod sensor 9, and the moisture detector body 301, the seeds can be detected in the sampler body 1. Compared with the traditional method of detecting grain seeds, which requires special equipment, this method is more convenient and efficient.

[0032] The working principle of this practical device is as follows: When performing seed testing, the sampler body 1 is quickly inserted into a grain bag via the pointed block 201. This allows the seeds in the bag to sequentially enter different storage troughs 105 from front to back. The operator then holds the gripping rod 502, causing the rotating block 501 to rotate counterclockwise. This causes the arc-shaped plate 8 to move clockwise from the arc-shaped groove 7 of the lower rod 101 to the arc-shaped groove 7 inside the upper rod 102, closing the upper end of the storage trough 105. This ensures that the seeds in the storage trough 105 do not spill when the sampler body 1 is then withdrawn. Furthermore, when the grain to be tested… After the seeds fall into the storage tank 105, the moisture detector body 301 is turned on by the control button 302, which powers the insertion rod sensor 9 and makes the insertion rod sensor 9 contact the seed to be tested. Since the moisture in the seed will affect the electrical parameters of the insertion rod sensor 9, the electrical parameters of the insertion rod sensor 9 can be observed through the display screen 303, thereby realizing the moisture measurement. By combining the sampler body 1, the insertion rod sensor 9 and the moisture detector body 301, the seeds can be detected in the sampler body 1. Compared with the traditional method of detecting grain seeds, which requires special equipment, this method is more convenient and efficient.
