Description

A plant biological activity detection device

Technical Field

The invention relates to a plant biological activity detection device, belonging to the technical field of plant component observation.

Background Art

Plant active ingredients refer to substances that constitute the body of plants. In addition to basic substances such as water, sugars, proteins, and fats, they also include secondary metabolites such as terpenes, flavonoids, alkaloids, steroids, lignin, and minerals. These substances have physiological promoting effects on humans and various organisms, so they are called plant active ingredients. Plant enzyme activity and component detection are indispensable links in the growth and metabolism of plants. Accurate test results can help plant scientists and farmers understand the growth status and metabolic characteristics of plants, formulate scientific planting plans, and improve the productivity and quality of plants. Commonly used plant component detection methods include high-performance liquid chromatography, gas chromatography, and ultraviolet spectrophotometry. When observing plant components, it is necessary to take several samples from plants at different growth stages and different parts, mix them and prepare them into uniform plant samples, grind the plant samples into fine powder, add an appropriate amount of solvent, and shake them for a period of time to dissolve the components in the plants. According to the selected detection method, the dissolved plant samples are injected into the detection instrument to observe the progress of the chemical reaction and calculate the content and proportion of the components in the plants.

When mixing a sample with a solvent, the existing method is mostly to place the powder sample and the solvent inside a test tube, and then oscillate them to allow them to react fully. Before extracting the solution after the reaction, the solution needs to be filtered to remove solid impurities. When filtering, a variety of filters need to be selected for filtration, so that when in use, the solution needs to be contacted with filters with different filter apertures multiple times. In this process, the solution will come into contact with bacteria or pollution sources in the air, thereby interfering with the test results.

Start the motor 2031, the motor 2031 drives the filter box 401 to rotate, open the feed pipe 202, pour the plant biological activity test liquid from the feed pipe 202 into the filter box 401, the test liquid passes through the first filter 4011, the second filter 4012 and the third filter 4013 in the filter box 401, and then enters the detection part 1 through the sampling tube 3, and the electromagnetic valve 301 is opened to detect the filtrate;

Close the solenoid valve 301, start the electric push rod 10041, the electric push rod 10041 drives the bottom plate 402 downward, the bottom of each filter moves out of the liquid outlet tank 5, and at the same time, the output end of the electric push rod 10041 drives the connecting plate 10086 downward, the connecting plate 10086 drives the first spline sleeve shaft 10083 downward, and the first spline sleeve shaft 10083 drives the second friction wheel 10081 downward through the first fixed shaft 10082. When the bottom plate 402 moves downward to the preset position, the bottom plate 402 squeezes the button 13, and the flushing pipe 10021 and the diversion pipe 10083 are flushed. Water starts to flow out of pipe 100111, and the residual impurities on the filter screen and the bottom plate 402 are washed to the slag guide plate 1005 by the water flow through the liquid outlet trough 5 and the edge of the bottom plate 402, and finally the filtered impurities are gathered on the slag guide plate 1005. At the same time, the second friction wheel 10081 contacts the first grinding groove wheel, and the second fixed shaft 10085 rotates. The second fixed shaft 10085 drives the limiting shaft 10071 to rotate through the belt 10087, and the scraper 10072 begins to gather the filtered impurities that fall on the slag guide plate 1005. The operator can remove the impurities through the slag discharge port 1006.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
