Description

Technical Field

[0001] This utility model relates to the field of agricultural product testing technology, and in particular to a sample collection device for testing the nutritional components of agricultural products. Background Technology

[0002] The collection of samples for agricultural product testing must follow regulations and procedures to ensure that the collected samples are representative, accurate, and traceable. Attention should also be paid to the circulation, preparation, and preservation of samples to ensure the accuracy and reliability of the test results and facilitate the collection and research of the data.

[0003] Patent document CN221468400U discloses a sample collection device for agricultural product testing. This device includes a collection rod body with a height adjustment component inside. The height adjustment component includes a sliding rod and insertion holes. The sliding rod is inserted into the collection rod body, and insertion holes are longitudinally arranged at the bottom of the sliding rod. In this invention, when the overall length of the collection rod body needs to be adjusted, the handle can be pulled down to pull the top of the push rod out of the insertion hole at the current position. Then, the sliding rod is slid and adjusted inside the collection rod body. When the desired length is reached, the handle is released, allowing the push rod to be inserted into the insertion hole at the current position by the spring and fixed. This achieves the adjustment and fixation of the overall length of the collection rod body, avoiding the inconvenience of using bolts in existing adjustment methods.

[0004] However, the agricultural product sample collection devices in the comparative documents generally lack reliable sealing and protection designs. During actual collection, especially in complex field environments, the collected agricultural products are prone to falling out of the device, resulting in insufficient sample volume and hindering the normal progress of testing. Furthermore, external dust and impurities can easily contaminate the samples, causing deviations in the test results and failing to accurately reflect the nutritional status of the agricultural products. Therefore, we provide a sample collection device for agricultural product nutritional component testing. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Example 1

[0029] The comparison document mentions a sampling device that lacks a sealing structure, leading to the sample easily falling out and causing damage. This embodiment provides a sample collection device for detecting the nutritional components of agricultural products. Please refer to [reference needed]. Figure 1 - Figure 6 This sample collection device for agricultural product nutrient analysis can seal the collected samples after collection, preventing them from falling and causing damage, and also preventing foreign matter from contaminating the samples and affecting the efficiency of nutrient component detection. The device includes a collection frame 1, with a sealing and protective mechanism 2 inside the collection frame 1 to enclose the space above it. An adjustment mechanism 3 is located on one side of the collection frame 1 to adjust the collection position. The sealing and protective mechanism 2 can seal and protect the collected samples, preventing them from falling and preventing foreign matter from contaminating them, thereby improving the detection effect of nutrient components. The adjustment mechanism 3 can quickly adjust the collection position within a certain range, thus increasing the collection rate and reducing the workload of staff.

[0030] Most of the agricultural product sample collection devices in the comparison documents have poor sealing and protection. During field collection, agricultural products are prone to falling off the device, resulting in insufficient collection volume, hindering the testing process. Furthermore, dust and impurities can mix into the sample, causing deviations in the test results and failing to accurately represent the nutritional components of the agricultural products. To solve the above problems, the sealing and protection mechanism 2 includes several sets of sliding columns 21 that are slidably connected to the inside of the top of the collection frame 1. The sliding columns 21 are triangularly distributed at the bottom of the turntable 22. The triangular distribution provides stable support for the turntable 22, ensuring that it remains balanced during rotation and preventing swaying or tilting. Moreover, the stability of the triangle helps to distribute the force. The turntable 22 is installed at the top of the sliding columns 21. The top of the turntable 22 has multiple sets of arc grooves 23. Sealing plates 24 are slidably connected inside the arc grooves 23. The area formed by the multiple sets of sealing plates 24 is the same as the area inside the top of the collection frame 1, which can achieve complete sealing of the top of the collection frame 1 and prevent the collection from being compromised. Agricultural products fall from the collection frame 1, improving collection efficiency and effectively blocking external dust and impurities from entering the collection frame 1, avoiding sample contamination and ensuring sample purity. A positioning post 25 is installed at the top of the sealing plate 24, and a cover plate 26 is slidably connected to the top of the positioning post 25. Several positioning grooves 27 adapted to the positioning post 25 are opened at the bottom of the cover plate 26. An installation plate 28 is installed on one side of the outer wall of the collection frame 1, and a waterproof motor 29 is installed at the bottom of the installation plate 28. A rotating gear 210 is installed at the output end of the waterproof motor 29, and a toothed ring 211 that meshes with the rotating gear 210 is installed on the outer wall of the turntable 22. After sample collection is completed, the operation of the waterproof motor 29 drives the rotating gear 210 to rotate. Through the meshing of the rotating gear 210 and the toothed ring 211, the turntable 22 rotates. Under the support of the arc groove 23, the multiple sets of sealing plates 24 rotate to a closed state, thereby sealing the top of the collection frame 1. This can prevent the sample from falling and can also effectively prevent foreign matter from mixing into the sample and affecting the detection efficiency of the sample's nutritional components.

[0031] Example 2

[0032] Based on Example 1, such as Figure 1 - Figure 6 As shown, based on the existing comparative documents, the collection device lacks a sealing structure, which makes the collected samples easy to fall and cause damage. However, the height adjustment function of the existing collection device is not good. Different types of agricultural products have large differences in growth height. Traditional collection devices are difficult to adjust the collection height flexibly and accurately. Operators often need to bend over, stand on tiptoe, or even use additional tools to collect agricultural products of different heights, which is inconvenient and inefficient. Therefore, this device is also equipped with a structure to adjust the collection position.

[0033] Current collection devices have shortcomings in height adjustment. Due to the uneven growth height of various agricultural products, traditional devices cannot flexibly and accurately adjust the collection height, which often requires operators to bend over, stand on tiptoe, or even use additional tools when collecting. This makes the operation cumbersome, seriously affects collection efficiency, and increases labor intensity. In order to solve the above problems... The adjustment mechanism 3 includes a toothed column 31 movably installed with the acquisition frame 1. The front end of the toothed column 31 is fixed to the acquisition frame 1 by bolts, allowing for quick assembly and disassembly of the acquisition frame 1. A fixing sleeve 32 is slidably connected to the outer wall of the toothed column 31. An inclined column 33 is installed at the other end of the fixing sleeve 32. A handle and elbow sleeve are installed on the other side of the inclined column 33, thereby improving the operating experience and work efficiency. The handle allows the operator to hold the device stably and apply force precisely when adjusting the height of the acquisition frame 1, ensuring a smooth and accurate adjustment process. The elbow sleeve provides support for the arm, reducing fatigue caused by prolonged operation. The elbow sleeve has a support groove on its inner side, and the elbow sleeve is made of silicone. The support groove conforms to the contour of the elbow, providing precise support for the elbow, distributing arm pressure, effectively relieving arm fatigue during prolonged operation, and improving operating comfort. The silicone material is soft and elastic, providing not only a good tactile feel but also anti-slip properties, making the operator's grip on the device more stable and preventing hand slippage from affecting the acquisition operation. To ensure the stability and accuracy of the collection process, a mounting rod 34 is rotatably connected inside the fixed sleeve 32. A drive gear 35 that meshes with the bottom end of the toothed column 31 is installed on the outer wall of the mounting rod 34. The drive gear 35 is distributed at the front end of the fixed sleeve 32, which can shorten the power transmission path, reduce energy loss, and ensure that the handle 38 can efficiently and timely drive the toothed column 31 to move up and down when it is turned, so as to accurately adjust the height of the collection frame 1. A rotating disk 36 is installed at the other end of the mounting rod 34. The rotating disk 36 is connected to the handle 38 through the connection of the drive disk 39 and the drive belt 37. The drive belt 37 plays a role in transmission and buffering, making the power transmission smoother and avoiding the impact and vibration caused by direct transmission from affecting the adjustment accuracy. This allows the operator to control the height of the collection frame 1 more easily and accurately, adapting to the collection needs of different agricultural products. The drive belt 37 is connected inside the rotating disk 36. A handle 38 is rotatably connected to one side of the fixed sleeve 32. The drive disk 39 connected to the drive belt 37 is installed at the connection end of the handle 38. When adjusting the sampling position according to the actual situation, the drive disk 39 is rotated by turning the throttle 38. Under the connection of the drive belt 37 and the rotating disk 36, the mounting rod 34 is rotated, which in turn drives the drive gear 35 to rotate. Through the meshing of the drive gear 35 with the bottom end of the toothed column 31, the position of the toothed column 31 can be adjusted, and the position of the sampling frame 1 can be changed, which facilitates the sampling of samples at different heights and improves the sampling efficiency.
