Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural protein extraction, in particular to a protein extraction device for bean sprout experiments. Background Technique
[0002] The bean sprout experiment is an experiment that simulates the growth process of bean sprouts. By cultivating bean sprouts in a specific environment, observing and recording their growth conditions, to study the growth laws and influencing factors of bean sprouts. In the experiment, usually, bean sprout seeds are soaked in water, and then placed under suitable temperature, humidity and light conditions to observe the germination, growth and development process of bean sprouts. By observing and measuring aspects such as the growth rate, morphological changes, and nutrient absorption of bean sprouts, the physiological mechanism and environmental requirements of bean sprout growth can be understood. For protein extraction in bean sprout experiments, bean sprouts in good growth condition and free from pests and diseases are selected as raw materials. Then, the bean sprouts are washed and dried to remove the water in them. Then, the dried bean sprouts are ground into powder. Subsequently, the bean sprout powder is mixed with an appropriate amount of solvent to fully dissolve the protein in it. Next, through centrifugal separation, the protein solution is separated from the bean sprout residue. Finally, the protein solution is concentrated, dried and crystallized to obtain high-purity bean sprout protein.
[0003] In bean sprout experiments, protein extraction is a key step, aiming to obtain a high-purity protein sample for subsequent analysis and application. However, during the actual operation process, when the protein sample is placed in the external environment for a long time, it is extremely vulnerable to contamination by impurities in the air. These impurities may come from various different sources, such as dust, bacteria, fungal spores, etc., which cause contamination of the protein sample. Once the protein sample is contaminated, the subsequent extraction and detection work cannot be carried out normally. This will not only waste resources and time, but may also lead to abnormal protein detection data, affecting the accuracy and reliability of the experimental results. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0028] Please refer to Figures 1 to 8, in the embodiment of the present utility model, a protein extraction device for bean sprout experiments includes a support column 1. A storage bin 2 is fixedly installed at the front end of the support column 1. An extraction groove is formed on the upper surface of the storage bin 2. A support 3 is fixedly installed at the upper end of the support column 1. A hydraulic rod 4 is fixedly installed in the middle of the support 3. The lower end of the hydraulic rod 4 is fixedly connected to an extraction plate 5. An extraction magnetic rod 6 is fixedly installed at the lower end of the extraction plate 5. A plurality of isolation mechanisms 8 are arranged inside the storage bin 2. The isolation mechanism 8 includes a closing door 801, a first partition plate 802, and a second partition plate 803. The closing door 801 is hinged to the front end of the storage bin 2. The first partition plate 802 and the second partition plate 803 are fixedly installed inside the storage bin 2. A pipe rack 9 is arranged between the first partition plate 802 and the second partition plate 803. Protein tubes 10 are placed on the pipe rack 9. The storage bin 2 is used to store the protein tubes 10 to be extracted. The first partition plate 802 and the second partition plate 803 inside the isolation mechanism 8 are used to isolate and classify different pipe racks 9 and protein tubes 10; the closing door 801 can cut off the air circulation between the storage bin 2 and the outside world and prevent impurities in the air from entering. The first partition plate 802 and the second partition plate 803 are key components in the isolation mechanism 8 to realize the isolation of multiple pipe racks 9. They are fixed inside the storage bin 2 to form an independent operation space and avoid cross-contamination between the protein tubes 10;
[0029] A plurality of dust-proof mechanisms 7 are arranged at the upper end of the storage bin 2. The dust-proof mechanism 7 includes a pressing plate 701, a telescopic rod 702, a spring 703, a shielding plate 704, a base 705, and a limiting rotating rod 706. The pressing plate 701 is fixedly installed on the upper surface of the storage bin 2. The telescopic rod 702 is fixedly installed on the pressing plate 701. The shielding plate 704 is fixedly installed at the end of the telescopic rod 702 away from the pressing plate 701. A base 705 is arranged in front of the telescopic rod 702. The limiting rotating rod 706 is rotatably installed on the base 705. The pressing plate 701 and the base 705 are fixedly welded on the upper surface of the storage bin 2. The shielding plate 704 is in a clamping connection with the limiting rotating rod 706. A spring 703 is arranged outside the telescopic rod 702. The telescopic rod 702 and the spring 703 are combined into a compression spring body. The pressing plate 701 effectively prevents impurities in the air from entering the inside of the storage bin 2 through the extraction groove. The telescopic rod 702 and the spring 703 cooperate to achieve the effects of support and compression, so that the shielding plate 704 can be quickly opened and closed. The spring 703 is a key component in the dust-proof mechanism 7 to provide a restoring force. It enables the telescopic rod 702 to quickly return to its original position after being released and at the same time ensures the tight closing of the shielding plate 704; the shielding plate 704 can be flexibly opened and closed to meet the needs of the extraction operation.
[0030] The working principle of the present utility model is as follows: When using this protein extraction device for bean sprout experiments, first, the protein tubes 10 loaded with protein samples are neatly arranged on the tube rack 9. Subsequently, the isolation mechanism 8 is enabled, and multiple tube racks 9 are successively pushed between the first partition 802 and the second partition 803 and the closing door 801 is rotated to close, sealing the storage bin 2. When extraction operation is required, the hydraulic rod 4 is connected to an external control terminal, and the dust-proof mechanism 7 is enabled to push the shielding plate 704, causing the telescopic rod 702 and the spring 703 to contract, and the shielding plate 704 no longer covers the extraction slot on the upper surface of the storage bin 2. At this time, the limiting rotating rod 706 is rotated and the limiting rotating rod 706 is engaged with the shielding plate 704 to fix the state of the shielding plate 704. Then, the hydraulic rod 4 is started, and the hydraulic rod 4 pushes the extraction plate 5 and the corresponding number of extraction magnetic rods 6 downward into the protein tubes 10 inside the storage bin 2, and the protein samples inside the protein tubes 10 are extracted using the magnetic bead method. After the extraction work is completed, only by releasing the engagement state between the limiting rotating rod 706 and the shielding plate 704, the shielding plate 704 will quickly return to its position and cover the extraction slot on the upper surface of the storage bin 2, sealing the storage bin 2 again. To sum up, the first partition 802 and the second partition 803 inside the isolation mechanism 8 are used to isolate and classify different tube racks 9 and protein tubes 10, ensuring that the protein samples to be extracted stored inside the storage bin 2 will not affect each other, effectively avoiding the contamination of protein samples and improving the accuracy of the later protein detection results. There is also a dust-proof mechanism 7, and enabling the dust-proof mechanism 7 can achieve rapid protein extraction operation without exposing protein samples for a long time.
[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
