Description

Technical Field

[0001] This utility model relates to the technical field of agricultural product sampling devices, specifically to an agricultural product testing and sampling device. Background Technology

[0002] Agricultural products are items produced in agricultural production and are also essential items for people's lives. Therefore, the testing requirements for agricultural products are relatively high, especially for crops that are prepared to be transported to agricultural wholesale markets from the production area or base, which need to be sampled and tested.

[0003] Chinese Patent Publication No. CN216484070U discloses an agricultural product testing and sampling device, including a base and a controller. The base has a placement platform, and a horizontal slide is located above the base. A sampling mechanism is slidably mounted on the horizontal slide. The sampling mechanism includes a lifting component and a sampling component. The sampling component is located below the lifting component, and the lifting component drives the sampling component to move up and down. The sampling component includes a mounting base, and a sampling blade is located at the bottom of the mounting base. The mounting base also has a pop-out component for driving the sample inside the sampling blade to pop outwards. The lifting component is electrically connected to the controller. This agricultural product testing and sampling device facilitates sampling of fruits and vegetables, reduces sampling difficulty, effectively lowers sampling difficulty, and improves sampling quality.

[0004] The aforementioned device uses a sampling blade to take samples from agricultural products, which are then placed in a sample tray for testing. However, after storing the sample, some residue remains on the inner wall of the sampling blade. If this residue is not cleaned, it can easily mix with subsequent agricultural product samples, leading to errors in the test results. Even replacing the sampling blade after sampling reduces sampling efficiency. Utility Model Content

[0005] To address the aforementioned issues, an agricultural product testing and sampling device is provided. An externally installed water pump sprays cleaning water through a spray pipe, while a drive motor powers the sampling cylinder to rotate at a uniform speed. During this process, a first cleaning brush installed on the outside of the sampling cylinder and a second cleaning brush installed on the inside thoroughly scrub the outer and inner surfaces of the cylinder. This dual cleaning mechanism effectively removes various agricultural product residues and stains from the inner and outer walls of the sampling cylinder, ensuring that the cleanliness of the sampling cylinder meets testing standards. This prevents contamination from residues from affecting the accuracy of subsequent agricultural product testing, guaranteeing the reliability and consistency of the test results.

[0006] To address the problems of existing technologies, this utility model provides an agricultural product testing and sampling device, including a sampling platform. A support plate is movably mounted on the top of the sampling platform, and a drive motor is mounted on the top of the support plate. The output shaft of the drive motor is connected to a rotating rod via a coupling. A sampling cylinder for sampling agricultural products is mounted at the bottom of the rotating rod. A sample pushing component is mounted inside the sampling cylinder. An electric clamping plate for holding agricultural products is mounted on the top of the sampling platform. A cleaning component for cleaning the sampling cylinder is also mounted on the top of the sampling platform.

[0007] Preferably, the cleaning assembly includes a cleaning cylinder disposed on the top of the sampling platform, a water spray pipe disposed inside the cleaning cylinder, a second cleaning brush disposed inside the cleaning cylinder for cleaning the inner wall of the sampling cylinder, and a first cleaning brush disposed on the inner wall of the cleaning cylinder for cleaning the outer wall of the sampling cylinder.

[0008] Preferably, the inside of the cleaning cylinder is provided with a drain outlet for discharging wastewater.

[0009] Preferably, the pushing assembly includes a pushing block movably disposed inside the sampling cylinder. Both sides of the top of the pushing block are provided with pressing rods. One end of the pressing rod extends to the outside of the sampling cylinder and is provided with an annular block. A compression spring is sleeved on the outside of the pressing rod. One end of the compression spring is connected to the bottom of the annular block, and the other end of the compression spring is connected to the top of the sampling cylinder.

[0010] Preferably, the top of the sampling platform is provided with a squeezing frame for abutting against the annular block, and the top of the sampling platform is also movably provided with a sample storage tray for collecting samples.

[0011] Preferably, the bottom of the sampling tube is provided with multiple conical blades for convenient sampling.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. An externally installed water pump sprays cleaning water through a spray pipe, while a drive motor powers the sampling cylinder to rotate at a constant speed. During this process, a first cleaning brush on the outside and a second cleaning brush on the inside of the sampling cylinder thoroughly scrub the outer and inner surfaces of the cylinder. This dual cleaning mechanism effectively removes various agricultural product residues and stains from the inner and outer walls of the sampling cylinder, ensuring that the cleanliness of the sampling cylinder meets testing standards. This prevents contamination from residues from affecting the accuracy of subsequent agricultural product testing, guaranteeing the reliability and consistency of test results.

[0014] 2. By moving the sampling cylinder and the annular block between the two extrusion frames, and then controlling the sampling cylinder to move upward, the annular block at the top of the sampling cylinder will not move under the action of the extrusion frame. Therefore, when the sampling cylinder moves upward, the sample inside will fall downward under the extrusion of the push block, so that the sample falls into the sample storage tray, which is convenient for later testing.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model provides:

[0024] A sampling device for agricultural product testing includes a sampling platform 1 with a support plate 2 movably mounted on top. A drive motor 3 is mounted on top of the support plate 2. The output shaft of the drive motor 3 is connected to a rotating rod 9 via a coupling. A sampling cylinder 4 for sampling agricultural products is mounted at the bottom of the rotating rod 9. A sample pushing component is installed inside the sampling cylinder 4. An electric clamping plate 5 for clamping agricultural products is mounted on top of the sampling platform 1. A cleaning component for cleaning the sampling cylinder 4 is also mounted on top of the sampling platform 1.

[0025] By placing the agricultural product to be tested on top of the electric clamping plate 5, the electric clamping plate 5 can clamp and limit the agricultural product to prevent it from shaking during sampling. Then, the sampling tube 4 is used to sample the agricultural product. Finally, the cleaning component is used to remove various agricultural product residues and stains remaining on the inner and outer walls of the sampling tube 4 to ensure that the cleanliness of the sampling tube 4 meets the testing standards.

[0026] like Figure 5 As shown, the cleaning assembly includes a cleaning cylinder 7 disposed on the top of the sampling stage 1. A water spray pipe 14 is disposed inside the cleaning cylinder 7. A second cleaning brush 16 for cleaning the inner wall of the sampling cylinder 4 is also disposed inside the cleaning cylinder 7. A first cleaning brush 15 for cleaning the outer wall of the sampling cylinder 4 is disposed on the inner wall of the cleaning cylinder 7.

[0027] An external water pump sprays clean water through a spray pipe 14, and a drive motor 3 drives the sampling cylinder 4 to rotate. At the same time, the first cleaning brush 15 and the second cleaning brush 16 can clean the outer and inner walls of the sampling cylinder 4 to prevent the residue from affecting the subsequent testing of agricultural products.

[0028] like Figure 5 As shown, the inside of the cleaning cylinder 7 is provided with a drain outlet for discharging sewage.

[0029] Wastewater is discharged through the drain outlet to prevent it from being pushed into the cleaning cylinder 7.

[0030] like Figure 3 As shown, the pushing assembly includes a pushing block 10 movably disposed inside the sampling cylinder 4. Both sides of the top of the pushing block 10 are provided with a pressing rod 11. One end of the pressing rod 11 extends to the outside of the sampling cylinder 4 and is provided with an annular block 8. A compression spring 12 is sleeved on the outside of the pressing rod 11. One end of the compression spring 12 is connected to the bottom of the annular block 8, and the other end of the compression spring 12 is connected to the top of the sampling cylinder 4.

[0031] By pushing block 10, the agricultural product sample inside sampling cylinder 4 can be squeezed out, causing the sample to fall into the sample storage tray 13 for later testing.

[0032] like Figure 4As shown, the top of the sampling platform 1 is provided with a squeezing frame 6 for abutting against the annular block 8, and the top of the sampling platform 1 is also movably provided with a sample storage tray 13 for collecting samples.

[0033] By moving the sampling cylinder 4 and the annular block 8 between the two extrusion frames 6, and then controlling the sampling cylinder 4 to move upward, the annular block 8 at the top of the sampling cylinder 4 will not move under the action of the extrusion frame 6. Therefore, when the sampling cylinder 4 moves upward, the sample inside it will fall downward under the extrusion of the push block 10.

[0034] like Figure 3 As shown, the bottom of the sampling cylinder 4 is equipped with multiple conical blades 17 for convenient sampling.

[0035] The conical blade 17 at the bottom of the sampling tube 4 makes it easy to sample agricultural products.

[0036] Working principle: When sampling agricultural products is required, the agricultural product to be tested is first placed on top of the electric clamp 5. The electric clamp 5 can clamp and limit the agricultural product to prevent it from shaking during sampling. Then, the drive motor 3 drives the sampling cylinder 4 to rotate. The agricultural product can be sampled through the conical cutter head 17 at the bottom of the sampling cylinder 4. Then, the sampling cylinder 4 and the annular block 8 are moved between the two extrusion frames 6. Then, the sampling cylinder 4 is controlled to move upward. The annular block 8 at the top of the sampling cylinder 4 does not move under the action of the extrusion frame 6. Therefore, when the sampling cylinder 4 moves upward, the sample inside is squeezed by the pushing block 10. The sample will fall downwards, allowing it to land inside the sample storage tray 13 for later testing. After the sample falls from the inside of the sampling tube 4, some residue will remain on its inner wall. At this time, the sampling tube 4 is moved to the inside of the cleaning tube 7. Then, an external water pump sprays clean water through the spray pipe 14, and the drive motor 3 drives the sampling tube 4 to rotate. At the same time, the first cleaning brush 15 and the second cleaning brush 16 can clean the outer and inner walls of the sampling tube 4 to prevent the remaining residue from affecting the subsequent testing of agricultural products. Finally, the used wastewater is discharged through the drain outlet to prevent wastewater from being pushed into the inside of the cleaning tube 7.

[0037] The above embodiments merely illustrate one or several implementation methods of the agricultural product testing and sampling device of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model.
