Description

Technical Field

[0001] The invention belongs to the technical field of plant sample drying, and in particular relates to an energy-saving plant sample continuous multi-layer drying device. Background Art

[0002] Plant samples usually refer to samples collected from specific plants, plant communities or ecosystems for research, analysis or experiments. These samples can be whole plants, parts of plants (such as roots, stems, leaves, flowers, fruits or seeds), or plant tissues, cells, secretions, etc.

[0003] The purposes of collecting plant samples include the following:

[0004] Botanists, ecologists, horticulturists, etc. may collect samples to study plant growth and development, genetic characteristics, physiological and biochemical processes, adaptability to the environment, and interactions with other organisms. In the agricultural field, the collection of plant samples helps to assess the health of crops, yield potential, pest and disease conditions, and the impact of soil and irrigation conditions on crops, which helps to formulate scientific agricultural management measures and improve crop yield and quality. Plants, as an important part of the ecosystem, are very sensitive to environmental factors such as environmental pollution and climate change. By analyzing indicators such as pollutant content, heavy metal accumulation, and isotope ratios in plant samples, it is possible to assess environmental quality, track pollution sources, and the impact of climate change. Many plants have medicinal value or can be used as food ingredients. Collecting and analyzing plant samples helps to discover new active ingredients, assess their safety and effectiveness, and thus promote the development of food and drugs.

[0005] Traditional methods of drying plant samples include sun exposure, air drying, shade drying, ventilation hanging storage, chemical reagent dehydration, heating drying, etc. Among them, heating drying is commonly used by scientific researchers. Fresh plants are rich in water and the juice in the plants contains organic matter. If they are not dried in time or the drying efficiency is low, they are prone to mold and rot, affecting the test results.

[0029] Embodiment 1

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an energy-saving plant sample continuous multi-layer drying device includes a drying box 1 and a plurality of support legs 2 installed at the bottom of the outer wall thereof and a feed pipe 3 installed at the top of the outer wall of the drying box 1, and also includes: a uniform vibration mechanism for uniformly drying the plant samples added to the drying box 1, the uniform vibration mechanism is located inside the drying box 1, and the uniform vibration mechanism includes a plurality of limit slides 5, a plurality of rotating magnetic blocks 506 and a heating element 405 opened on one side of the inner wall of the drying box 1, and the limit slide 5 is fixedly connected to the limit vertical rod 50 1.

The bottom of the drying box 1 is inclined, and a discharge port is provided on one side of the bottom of the drying box 1, and the discharge port is corresponding to the inclined position of the bottom of the drying box 1. The discharge pipe 3 is connected to the inside of the drying box 1, and a plurality of vibration magnetic plates 504 are arranged in layers in sequence.

[0031] The present invention further specifically describes that the rotating magnetic block 506 and the vibrating magnetic plate 504 are arranged to attract each other with opposite poles, a plurality of filter holes are provided on the vibrating magnetic plate 504, and the size of the filter holes is larger than the size of the plant sample, the outer wall of the vibrating magnetic plate 504 and the inner wall of the drying box 1 are arranged to slide and fit, and the end of the vibrating spring 503 away from the limiting slide groove 5 is connected to the limiting slider 502;

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the drying box 1 is connected with a rotating heating mechanism for uniformly stirring and heating the plant samples added to the drying box 1, and the rotating heating mechanism includes a servo motor 4 installed on the outer wall of the drying box 1 through an L-shaped plate, and the interior of the drying box 1 is rotatably connected with multiple transmission shafts 4010 and a rotating shaft 401, and the multiple transmission shafts 4010 and the one rotating shaft 401 are all rotatably extended to the outside of the drying box 1, and the outer wall of the rotating shaft 401 is fixedly connected with multiple rotating blocks 402, and the outer wall of the rotating block 402 is fixedly connected with multiple rotating sleeves 409, and the interior of the rotating sleeve 409 is fixedly connected with a telescopic spring 403, and one side of the telescopic spring 403 is fixedly connected with a limiting slide 404, and a heating switch 406 is provided on one side of the inner wall of the rotating sleeve 409, and one side of the limiting slide 404 is fixedly connected with a connecting rod 407, and the end of the connecting rod 407 away from the limiting slide 404 is fixedly connected with a sliding pressing block 408;

[0033] The present invention is further specifically described in detail, the heating element 405 is connected to one side of the limiting slide 404, and the end of the heating element 405 away from the limiting slide 404 slides and extends to the outside of the rotating sleeve 409, the rotating magnetic block 506 is fixedly installed at the end of the heating element 405, the end of the rotating shaft 401 away from the drying box 1 is fixedly connected to the output end of the servo motor 4, and multiple transmission shafts 4010 are connected to the rotating shaft 401 through a transmission belt transmission. The outer wall of the limiting slide 404 and the inner wall of the rotating sleeve 409 are slidingly fitted, the limiting slide 404 and the sliding pressure block 408 are correspondingly extruded with the heating switch 406, and the interior of the rotating sleeve 409 is located between the limiting slide 404 and the inner wall of the rotating sleeve 409 and is filled with an easily expandable gas, and the easily expandable gas is one of hydrogen or nitrogen;

[0034] As can be seen from the above, when the staff heats and dries the plant samples, they turn on the servo motor 4 to make it work, and accordingly drive the rotating shaft 401 to rotate. According to the effect of the transmission belt, multiple transmission shafts 4010 can be driven to rotate, and then multiple rotating blocks 402 can be driven to rotate. According to the effect of the rotating centrifugal force, the heating element 405 can drive the limiting slide 404 to slide and extend to the outside of the rotating sleeve 409, so that the limiting slide 404 is separated from the heating switch 406, so that the heating element 405 is heated and used. With the heating of the heating element 405, the temperature inside the drying box 1 can be increased. By utilizing the rotation of the heating element 405, the heat generated by the heating of the heating element 405 can be rotated and filled into the interior of the drying box 1, thereby improving the drying temperature inside the drying box 1.

[0035] At this time, the plant samples to be dried are added to the interior of the drying box 1 through the feed tube 3. The corresponding functions of the multiple heating elements 405 and the feed tube 3 can be used to stir and break up the plant samples added to the drying box 1 so that they fall evenly on the vibrating magnetic plate 504. When the rotating magnetic block 506 at the end of the heating element 405 rotates to correspond to the vibrating magnetic plate 504, the vibrating magnetic plate 504 can be made to vibrate and evenly dry the plant samples that fall on the vibrating magnetic plate 504 according to the effect of the attraction between the opposite poles of the two. Through the setting of this structure, the plant samples added to the drying box 1 can be vibrated and evenly dried by using the multi-layer vibrating magnetic plate 504. In addition, the corresponding functions of the feed tube 3 and the multiple heating elements 405 can be used to break up the plant samples, thereby avoiding the accumulation of the plant samples added to the drying box 1, thereby improving the sufficiency of the plant samples in the drying box 1 and improving the working efficiency of the drying box 1 for drying the plant samples.

[0036] The bottom of the drying box 1 is tilted to increase the efficiency of the plant sample flowing out through the discharge port;

[0037] By utilizing the cooperation between the limit slide plate 404 and the heating switch 406, the heating element 405 can be automatically turned on and heated when the servo motor 4 is turned on, which correspondingly reduces the number of operating steps for the staff to turn on and heat the heating element 405;

[0038] It should be noted that the heating element 405 is a heating component, and the heating switch 406 is a kind of touch switch, which is a switch used to turn on the heating element 405. The above are all prior arts, and their working principles are not described in detail.

[0039] It should be noted that the feed pipe 3 and the heating element 405 are arranged correspondingly, and a plurality of ventilation nets are provided on the outer wall of the drying box 1;

[0040] As the interior of the drying box 1 is continuously heated, the easily expandable gas can be heated and expanded, causing the easily expandable gas to expand and slide on the limiting slide 404, so that the limiting slide 404 drives the sliding pressure block 408 at the end of the connecting rod 407 to squeeze the heating switch 406 again, so that the heating element 405 can be turned off, thereby preventing the heating element 405 from continuously heating and causing the temperature inside the drying box 1 to be too high. By utilizing the effect of opening a plurality of ventilation nets on the outer wall of the drying box 1, the air circulation inside the drying box 1 is increased, thereby improving the drying efficiency of the drying box 1 for drying and heating plant samples.

[0041] Embodiment 2

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a reciprocating agent discharging mechanism is arranged inside the rotating heating mechanism, which is used to spray the water absorbing agent when stirring and heating the plant sample. The reciprocating agent discharging mechanism includes an agent feeding hose 6 connected to the outer wall of the rotating block 402, and the agent feeding hose 6 extends to the inside of the rotating sleeve 409 and extends to the outside of one side of the limiting slide plate 404. An agent discharging port 601 is provided at one end of the rotating sleeve 409, and tension springs 602 are connected to the inside of the rotating sleeve 409 on both sides of the agent discharging port 601, a sliding rod 603 is connected between the two tension springs 602, and a fitting baffle 604 is fixedly connected to one end of the sliding rod 603;

[0043] The present invention is further specifically described in detail that the interiors of the plurality of transmission shafts 4010, the rotating shaft 401 and the rotating block 402 are all hollow, the interiors of the transmission shaft 4010 and the rotating shaft 401 are connected to the interior of the rotating block 402, the rotating block 402 is connected to the interior of the rotating sleeve 409 through the inlet hose 6, the fitting baffle 604 is located inside the outlet 601, the outer wall of the fitting baffle 604 and the inner wall of the outlet 601 are slidingly fitted, the outer wall diameter of the sliding rod 603 is smaller than the inner wall diameter of the outlet 601, and the outer walls of the transmission shaft 4010 and the rotating shaft 401 are provided with inlet holes;

[0044] As can be seen from the above, when the heating element 405 and the vibrating magnetic plate 504 are attracted to each other with opposite poles, the heating element 405 can slide and extend to the outside of the rotating sleeve 409 again, squeezing the inside of the rotating sleeve 409, causing the fitting baffle 604 to slide to the outside of the agent outlet 601, so that the water absorbent inside the rotating sleeve 409 flows out, contacts the plant sample inside the drying box 1, and absorbs moisture from its outer wall, thereby improving the drying effect of the plant sample.

[0045] Furthermore, the present design application is applied to drying plant samples. By utilizing the function of the multi-layer vibrating magnetic plates 504, the plant samples added to the drying box 1 can be vibrated and dried uniformly. In addition, the corresponding settings of the feed pipe 3 and the multiple heating elements 405 can break up the plant samples, thereby avoiding the accumulation of plant samples added to the drying box 1, thereby improving the sufficiency of the plant samples inside the drying box 1 and improving the working efficiency of the drying box 1 for drying plant samples.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
