Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural product sampling technology, and in particular to a sampler for agricultural product testing. Background Technology
[0002] With the continuous improvement of the agricultural product quality and safety testing system, traditional manual sampling methods are inefficient and prone to errors, making it difficult to meet the needs of large-scale and high-precision agricultural product testing. Therefore, the sampling device for agricultural product testing has developed rapidly to meet the demand. It is widely used in agricultural product processing, grain storage, food testing, agricultural research and other industries. In the grain purchasing process, it can be used to sample major grains such as wheat, rice and corn.
[0003] Structurally, the sampler mainly consists of a feeding device, a sampling mechanism, a sample receiving device, and a control unit. The feeding device is responsible for uniformly introducing the agricultural products to be sampled into the equipment. The sampling mechanism achieves uniform sample division through a specific mechanical structure. The sample receiving device is used to collect the divided sub-samples. The control unit can adjust parameters such as the sampling ratio and speed according to needs to ensure the accuracy and controllability of the sampling process. Its main function is to uniformly divide a large number of original agricultural product samples into several representative sub-samples according to a certain ratio or weight. The physical properties and chemical composition of these sub-samples are consistent with the original samples, providing accurate and reliable test samples for subsequent agricultural product quality testing. This effectively avoids deviations in test results caused by sample inhomogeneity, ensures the authenticity and validity of agricultural product test data, and thus provides a scientific basis for agricultural product quality control, market access, and quality grading.
[0004] Traditional sample dividers lack a graded filtration design, which easily leads to clogging of the crushing chamber. Furthermore, the resulting sample particles are uneven, affecting the accuracy of subsequent testing. In addition, the filter plates are mostly fixed structures, making disassembly and assembly cumbersome and difficult to replace with different pore sizes, thus failing to adapt to a wide variety of agricultural products and exhibiting poor versatility. Therefore, a sample divider for agricultural product testing is proposed to solve the above problems. Utility Model Content

[0031] 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.
[0032] Reference Figures 1-4 An embodiment of this utility model provides a sampler for agricultural product testing, comprising a base plate 1 and a crushing chamber 3. Reinforcing rods 8 are fixedly connected to both sides of the outer wall of the crushing chamber 3. The end of the reinforcing rod 8 away from the crushing chamber 3 is fixedly connected to the top of the base plate 1. A feed hopper 5 is fixedly connected to the top of the crushing chamber 3. Locking sleeves 9 are fixedly connected to both sides of the outer wall of the feed hopper 5. A stop block 14 is fixedly connected to the inner wall of the locking sleeve 9. A locking pin 16 is slidably connected to the inner wall of the locking sleeve 9. A first spring 15 is sleeved on the outer wall of the locking pin 16. The locking pin 16 is slidably connected to the inner wall of the stop block 14.
[0033] First, the material is initially screened and filtered through the first filter plate 10. Utilizing the elastic potential energy of the first spring 15, the engagement between the pin 16, the locking sleeve 9, and the stop block 14 allows for the rapid installation and disassembly of the first filter plate 10 and the feed hopper 5. The agricultural products to be tested are fed into the feed hopper 5 for initial screening and then enter the crushing chamber 3. In the crushing chamber 3, the agricultural products are crushed. During this process, the reinforcing rods 8 on both sides provide stable support for the crushing chamber 3, keeping it stable on the bottom plate 1 and ensuring a smooth crushing process. After crushing, the material can be further processed for subsequent agricultural product testing operations such as sampling.
[0034] Reference Figures 3-4 The inner wall of the feed hopper 5 is movably connected to a first filter plate 10. Locking blocks 12 are fixedly connected to both sides of the inner wall of the first filter plate 10. A locking block 13 is fixedly connected to the outer wall of the locking pin 16. The locking block 13 and the locking block 12 are engaged.
[0035] First, place the first filter plate 10 into the inner wall of the feed hopper 5, aligning the locking blocks 12 on both sides with the locking blocks 13 in the locking sleeve 9. Push and twist the locking pin 16 to make it slide along the inner wall of the locking sleeve 9 and the stop block 14. At this time, the first spring 15 is compressed, and the locking block 13 moves with the locking pin 16 and engages with the locking block 12, thus fixing the first filter plate 10. When agricultural products are put into the feed hopper 5, the first filter plate 10 will filter out impurities or clumps that are too large, avoiding clogging of the crushing chamber 3. When it is necessary to clean or replace filter plates with different apertures, pull the locking pin 16 in the opposite direction, and the first spring 15 will reset and drive the locking block 13 to disengage from the locking block 12, so that the first filter plate 10 can be quickly removed. The operation is convenient and does not affect the subsequent sampling process, adapting to the diversity of agricultural products.
[0036] Reference Figure 5The inner wall of the crushing chamber 3 is fixedly connected with several fixed blocks 19. The outer wall of the fixed blocks 19 is fixedly connected with a second spring 17. The end of the second spring 17 away from the fixed blocks 19 is fixedly connected with a second filter plate 20. The outer wall of the second filter plate 20 is fixedly connected with a vibration motor 18.
[0037] The inner wall of the crushing chamber 3 is fixed with a second spring 17 by a fixing block 19. The other end of the second spring 17 is connected to the second filter plate 20 to form an elastic support structure. When the crushed agricultural products enter the lower part of the crushing chamber 3, the vibration motor 18 is started, which drives the second filter plate 20 to vibrate at high frequency. During the vibration, fine materials that meet the requirements for testing and sampling will pass through the second filter plate 20 and enter the subsequent sampling stage. Larger particles or incompletely crushed materials are intercepted and can be crushed again. At the same time, the second spring 17 extends and retracts with the vibration, which increases the vibration amplitude of the filter plate and effectively avoids material clogging the filter holes, ensuring that the filtration and sampling process is continuous and efficient.
[0038] Reference Figure 4 One end of the first spring 15 is fixedly connected to the outer wall of the stop block 14, and the other end of the first spring 15 is fixedly connected to the inner wall of the lock sleeve 9.
[0039] When fixing the first filter plate 10, push the locking pin 16 to slide along the locking sleeve 9 and the stop block 14. The first spring 15 is compressed, and the locking block 13 moves with the locking pin 16 and engages with the locking block 12 to complete the fixing. When disassembling, pull the locking pin 16 in the opposite direction, the first spring 15 returns to its original position, and the locking block 13 disengages from the locking block 12, so that the first filter plate 10 can be taken out. The operation is convenient and can also ensure the stability of the filter plate and prevent it from loosening when separating samples.
[0040] Reference Figures 1-3 The outer wall of the feed hopper 5 has an insertion hole 11, and the locking pin 16 is slidably connected inside the insertion hole 11.
[0041] When assembling the first filter plate 10, push the locking pin 16 so that it slides along the insertion hole 11 of the locking sleeve 9, the stop block 14 and the feed hopper 5. The first spring 15 is compressed, and the locking block 13 moves with the locking pin 16 and engages with the locking block 12 to complete the fixing of the filter plate. When disassembling, pull the locking pin 16 in the opposite direction, the first spring 15 returns to its original position, the locking pin 16 retracts along the insertion hole 11, the locking block 13 disengages from the locking block 12, and the filter plate can be taken out. The insertion hole 11 ensures the stability of the sliding of the locking pin.
[0042] Reference Figures 3-4 The inner wall of the crushing chamber 3 is rotatably connected with several crushing wheels 21, and the second filter plate 20 is located directly below the crushing wheels 21.
[0043] After agricultural products enter the crushing chamber 3 through the feed hopper 5, the crushing wheel 21 on the inner wall rotates to crush them. The crushed material falls to the second filter plate 20 directly below. Fine materials that meet the requirements pass through the filter plate, while large pieces are intercepted to ensure that the subsequent sample distribution is uniform.
[0044] Reference Figures 1-2 Two material distribution hoppers 2 are fixedly connected to the bottom of the crushing chamber 3, and two material receiving tanks 7 are fixedly connected to the top of the bottom plate 1. The material distribution hoppers 2 are located directly above the material receiving tanks 7.
[0045] After being processed by the crushing chamber 3, the material falls into the two bottom distribution hoppers 2. Guided by the distribution hoppers 2, it falls precisely into the two receiving tanks 7 on the bottom plate 1 directly below, completing the uniform distribution and collection of the material, and providing an equal amount of sample for subsequent testing.
[0046] Reference Figure 1 A control box 6 is fixedly connected to the top of the base plate 1, and a reinforcing member 4 is fixedly connected at the connection between the crushing chamber 3 and the feed hopper 5.
[0047] The control box 6 regulates the overall operation, ensuring the orderly crushing and sorting process. The reinforcement 4 at the connection between the feed hopper 5 and the crushing chamber 3 enhances the stability of the connection between the two, reduces the shaking caused by material impact, ensures that agricultural products enter the crushing chamber 3 smoothly, and improves the reliability of equipment operation.
[0048] Working principle: First, the first filter plate 10 is fixed by the cooperation of the locking sleeve 9, the stop block 14, the first spring 15 and the locking pin 16. The locking pin 16 is pushed to slide along the locking sleeve 9, the stop block 14 and the insertion hole 11 of the feed hopper 5. The first spring 15 is compressed, and the locking block 13 and the locking block 12 are engaged to fix the first filter plate 10 to the inner wall of the feed hopper 5. The operator starts the equipment through the control box 6. The agricultural products to be tested are put into the feed hopper 5. After the first filter plate 10 filters out large impurities, they enter the crushing chamber 3. The reinforcement 4 at the connection between the feed hopper 5 and the crushing chamber 3 enhances the connection stability. The reinforcing rods 8 on both sides of the crushing chamber 3 support it firmly on the base plate 1.
[0049] The crushing wheel 21 inside the crushing chamber 3 rotates to crush agricultural products. The crushed material falls to the second filter plate 20 below. The vibration motor 18 drives the second filter plate 20 to vibrate. The second spring 17 extends and retracts with the vibration to increase the amplitude. Fine materials that meet the requirements pass through the filter plate and are guided by the two distribution hoppers 2 at the bottom of the crushing chamber 3 to fall precisely into the corresponding receiving tanks 7 on the bottom plate 1, completing the sample division and providing uniform samples for subsequent testing.
[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
