Description

Technical Field

[0001] The invention belongs to the technical field of plant specimen preparation, and in particular relates to a plant specimen rapid drying device. Background Art

[0002] As human activities have intensified their impact on the natural environment, the extinction rate of species has accelerated. Establishing a specimen museum has become an effective means of protecting biodiversity. It also helps to carry out popular science education and improve the public's awareness of biodiversity and protection. The collection and production of plant specimens play a vital role in scientific research and teaching. They are not only a powerful means to solve the problem of botanical teaching aids, but also can break through regional and seasonal restrictions, allowing teaching and research activities to continue. In addition, plant specimens can also help scientists preserve the morphology and color of plants for a long time, which is convenient for future re-observation and research.

[0003] The drying process is a key step in the preparation of plant specimens in the study. Its main purpose is to allow the water in the plant to be absorbed and evaporated by the paper in a short time, so as to ensure that the specimens can be preserved for a long time without mildew. Through drying, the specimens can be effectively prevented from corruption caused by moisture and the shelf life of the specimens can be extended.

[0004] Drying methods for plant specimens include natural drying and equipment drying. However, natural drying is slow, so a larger space is needed to hang or spread out the specimens to facilitate the evaporation of water, which not only takes up more physical space, but also takes a long time to complete the drying process. The existing equipment drying method is to set a specimen placement rack in a closed box, and then introduce hot air into the box to dry the specimens. Although this method improves the drying efficiency compared to self-heating, it often causes the temperature of the specimen to be too high or too low in some parts during the drying process, resulting in uneven heating of the specimens, especially in the initial heating of the specimens. Due to the high moisture content inside the plant specimens, uneven heating will cause the shrinkage of tissues at different positions of the specimens to increase, thereby causing the specimens to undergo large deformations and cracks, affecting subsequent use. Summary of the invention

[0040] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0042] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0043] See also Figures 1 to 9 As shown, in order to effectively control the direction of the hot air flow, the hot air can fully and evenly contact different positions of the plant specimen, reduce the difference in tissue contraction at different positions of the plant specimen, and facilitate the intact formation of the plant specimen. This embodiment provides a plant specimen rapid drying device, including a drying box 1, a gas heater 2, a gas guide component 3, a specimen fixing component and a rotating component 6.

[0044] See also Figures 1 to 5As shown, the gas flow guide assembly 3 includes an air supply pump 31, an exhaust pump 32, a diffusion cover 33 and an air collecting cover 34. The diffusion cover 33 and the air collecting cover 34 are arranged opposite to each other and are respectively installed on two opposite side walls of the drying box 1. The diffusion cover 33 and the air collecting cover 34 are both connected to the drying box 1. The air inlet of the air supply pump 31 is connected to the hot air outlet of the gas heater 2, the air outlet of the air supply pump 31 is connected to the diffusion cover 33, and the air inlet of the exhaust pump 32 is connected to the air collecting cover 34. The specimen fixing assembly is arranged in the drying box 1 and placed between the diffusion cover 33 and the air collecting cover 34, and includes two clamping parts 4 and a locking part 5. The two clamping parts 4 are arranged opposite to each other for clamping the plant specimens, and the locking part 5 is used to fix the two clamping parts 4. The rotating assembly 6 is arranged between the specimen fixing assembly and the bottom wall of the drying box 1, and the rotating assembly 6 has a rotating disk 61, and the rotating disk 61 is connected to one of the clamping parts 4.

[0045] When in use, the plant specimen to be dried is horizontally fixed on the rotating disk 61 of the rotating assembly 6 through the specimen fixing assembly, and at this time the specimen fixing frame is horizontally placed between the diffusion hood 33 and the air collecting hood 34, and then the hot air produced in the gas heater 2 can be transported to the drying box 1 through the diffusion hood 33 by the air supply pump 31. At the same time, the exhaust pump 32 will guide and discharge the hot air entering the drying box 1 through the collecting groove on the opposite side of the diffusion hood 33. In this way, with the continuous operation of the air supply pump 31 and the exhaust pump 32, a continuous directional hot air flow can be formed between the diffusion hood 33 and the air collecting hood 34. It is preferred that the formed directional hot air flow is in a horizontal flow state. Then, the rotating component 6 is started to drive the specimen fixing component to rotate, so that the specimen fixing frame can turn different directions with the plant specimen to be dried to a position parallel to the directional hot air flow, that is, under the rotation of the specimen fixing frame, the plant specimen to be dried can be circulated at different positions close to the diffusion cover 33, so that under the directional control of the hot air flow direction, the loss of hot air can be effectively reduced, so that the plant specimen is heated to a similar degree at each position of the directional hot air flow, and the heating is more uniform, thereby effectively reducing the difference in tissue contraction at different positions of the plant specimen, and facilitating the intact formation of the plant specimen.

[0046] Furthermore, in order to ensure that the hot air sent into the drying box 1 can be kept continuous and at a stable temperature, and to save the output power of the gas heater 2, the gas outlet of the exhaust pump 32 is connected to the gas inlet of the gas heater 2. Therefore, when in use, the hot air extracted from the drying box 1 by the exhaust pump 32 will enter the gas heater 2 again, realizing the recycling of hot air. Compared with directly extracting cold air, the efficiency of gas heating will be higher, and by utilizing the hot air circulation, the output power of the gas heater 2 can be appropriately reduced.

[0047] See also Figure 3 and Fig. 9As shown, further, in order to improve the hot air sent into the drying box 1 to fully and evenly contact the plant specimen, the diffusion cover 33 and the air collecting cover 34 with the same design structure include a cover body 331, a diversion cavity 332 and a plurality of diversion pipes 333. During installation, the cover body 331 has an opening, and the opening of the cover body 331 is connected to the drying box 1 by means of a corresponding through hole on the drying box 1. Preferably, the length of the cover body 331 is adapted to the length of the side wall of the drying box 1, and the corresponding through hole on the drying box 1 is also adapted to the length of the cover body 331; further, a diversion chamber 332 is provided at one end of the outer side of the cover body 331, and the diversion chamber 332 is connected to the air outlet of the air supply pump 31 or the air inlet of the exhaust pump 32 through a hose, and a plurality of diversion pipes 333 are arranged in parallel in the vertical direction and inserted in the cover body 331, and one end of the diversion pipe 333 passes through the cover body 331 and is connected to the diversion chamber 332, and further, a plurality of jet holes 334 are evenly distributed on the side wall of the diversion pipe 333 located in the cover body 331 and facing the drying box 1.

[0048] In this way, when in use, the air pump 31 sends hot air into the diversion chamber 332 through the hose, and the diverted hot air passing through the diversion chamber 332 enters each diversion pipe 333 respectively. At this time, the diversion pipe 333 pumps hot air into the drying box 1 at different axial positions of the diversion pipe 333 through the jet holes 334 evenly distributed on the side wall, and the diversion pipe 333 located on one side of the air collecting hood 34 extracts the hot air in the drying box 1 from the jet holes 334 at different positions under the suction pressure of the exhaust pump 32, so that the arrangement of the multiple diversion pipes 333 on both sides forms a hot air layer with a certain thickness and continuous flow in the drying box 1, that is, the unit coverage area of ​​the directional hot air flow is increased, and by placing the plant specimen in the flowing hot air layer and rotating the rotating component 6, each part of the plant specimen can be evenly exposed to the hot air, and the drying is more even, which effectively reduces the difference in tissue shrinkage at different positions of the plant specimen, and facilitates the intact formation of the plant specimen.

[0049] See also Figures 3 to 6As shown, further, in order to ensure that the plant specimens can reduce deformation during the drying process and ensure uniform heating as a whole, the clamping part 4 includes a fixing plate 41, a clamping plate 42 and an elastic member 43. The fixing plate 41 and the clamping plate 42 are arranged parallel to each other and both are in a horizontal state. The fixing plate 41 and the clamping plate 42 are both arranged between the diffusion cover 33 and the air collecting cover 34. A plurality of air holes 53 are evenly distributed on the clamping plate 42; preferably, the clamping plate 42 is made of a material with good air permeability; and then the elastic member 43 is arranged on the fixing plate 41 and the clamping plate 42 bracket, and the elastic member 43 is composed of a plurality of columns 431 and a plurality of first springs 432 arranged in a one-to-one correspondence. Preferably, the number of the main body can be adjusted according to the number of the clamping plate 41 and the clamping plate 42. 2 or the shape of the fixed plate 41 is quantitative. The clamping plate 42 and the fixed plate 41 designed in the present device are both rectangular, so four columns 431 and first springs 432 are used. The four columns 431 are evenly distributed at the four corners of the fixed plate 41. The columns 431 and the fixed plate 41 are vertically fixed. The clamping plate 42 is sleeved on the columns 431 and the two are slidably connected; multiple first springs 432 are respectively sleeved on the corresponding columns 431, and one end of the first spring 432 abuts against the fixed plate 41, and the other end abuts against the clamping plate 42. Preferably, the initial state of the two clamping plates 42 is a fitted state.

[0050] When in use, remove the locking part 5, then remove the upper clamping part 4, and then wrap the plant specimen to be dried with corrugated paper or absorbent paper for preliminary clamping. The thickness of the corrugated paper and absorbent paper is increased or decreased according to the adaptability of different plant specimens, and then the plant specimen clamped by the corrugated paper and absorbent paper is flattened on the lower clamping plate 42, and then the upper clamping part 4 is reset, and then the fixing plates 41 of the two clamping parts 4 are locked by the locking part 5. At this time, the clamping plates 42 on both sides can adaptively produce clamping force on the plant specimen under the action of the first spring 432, and the wrapping of corrugated paper and absorbent paper can not only speed up the drying of the plant specimen, but also prevent the holes on the clamping plate 42 from damaging the specimen or causing irreversible indentations. The plant specimen is fixed, and a certain gap is maintained between the fixing plate 41 and the clamping plate 42 by the spring. At this time, under the flow of hot air, the directional hot air flow will pass through the gap between the fixed plate 41 and the clamping plate 42 and the gap between the two clamping plates 42, and in the process of passing through the gap between the fixed plate 41 and the clamping plate 42, the hot air flow will evenly contact the plant specimen through the air holes 53 on the clamping plate 42, thereby ensuring that the overall heating of the plant specimen is uniform.

[0051] See also Figure 5 and Figure 6As shown, in order to fix the plant specimen, the locking portion 5 includes at least two clamping grooves 51, which are arranged on opposite sides of the fixing plate 41. The clamping grooves 51 are arranged in a C shape. The upper and lower side walls of the clamping grooves 51 are respectively clamped on the outer side walls of the two oppositely arranged fixing plates 41 and fastened by bolts 52. Air holes 53 are opened on the side walls of the clamping grooves 51. The fixed width of the clamping grooves 51 can keep the distance between the two fixing plates 41 constant, so that the two clamping plates 42 can be stressed under the action of the first spring 432 when clamping the plant specimen, so as to better clamp the plant specimen stably.

[0052] See also Figure 4 , Figure 5 and Figure 7 As shown, further, in order to improve the uniform heating of the plant specimen as a whole, a guide block 7 is arranged between the fixed plate 41 and the clamping plate 42. One side of the guide block 7 is fixedly connected to the fixed plate 41, and a gap is arranged between the other side and the clamping plate 42. The side walls of the guide block 7 adjacent to the fixed plate 41 and the clamping plate 42 are all arranged in an arc shape to guide the hot air to the direction of the clamping plate 42. In actual use, the local position of the plant specimen at the center of the two clamping plates 42 will lose a certain amount of heat when reaching the center of the clamping plate 42 due to the certain distance between the diffusible cover 33. At this time, due to the arc setting of the surrounding side of the guide block 7, the hot air flow is guided to a certain extent, so that the hot air flow flowing to the center of the clamping plate 42 can be gathered closer to the plant specimen, so that the heating temperature of the middle position of the plant specimen is closer to the heating temperature of the side, so that the plant specimen as a whole is heated evenly.

[0053] See also Figure 4 , Figure 5 and Figure 7 As shown, further, in order to allow the local position of the plant specimen in the middle of the clamping plate 42 to be fully heated and improve the uniformity of heating. A groove 8 is provided on the side wall of the guide block 7 facing the clamping plate 42, and a heat preservation block 9 is inserted in the groove 8. The heat preservation block 9 and the side wall perpendicular to the clamping plate 42 are provided with air flow channels, and a plurality of second springs 10 are provided between the heat preservation block 9 and the bottom wall of the groove 8. In the process of clamping the plant specimen, the heat preservation blocks 9 on both sides will be pressed against the clamping plate 42 under the action of the second spring 10. At this time, the hot air will pass through the air flow channel on the heat preservation block 9, and the heat passing through the air flow channel will be absorbed by the heat preservation block 9. The heat preservation block 9 generates a certain stability, thereby using the stable heat on the heat preservation block 9 to transfer to the clamping plate 42, so that the middle of the plant specimen is better heated, and the heating temperature of the middle position of the plant specimen is closer to the heating temperature of the side, so that the whole plant specimen is heated evenly.

[0054] See also Figure 5 and Figure 8As shown, further, in order to allow different positions of the plant specimen to circulate through the position of the diffusion cover 33, the uniformity of heating of the plant specimen is improved. The rotating assembly 6 includes a rotator 62, a rotating disk 61, an incomplete gear 63, a transmission shaft 64 and a driven gear 65. The rotator 62 is fixed on the bottom wall of the drying box 1. The rotator 62 is preferably a DC motor or a servo motor, and the rotator 62 has a rotating shaft; the incomplete gear 63 is fixed on the rotating shaft; the upper end of the transmission shaft 64 is fixedly connected to one of the fixed plates 41 through the rotating disk 61, and the lower end is rotatably connected to the bottom wall of the drying box 1; the driven gear 65 is fixed on the transmission shaft 64, and the driven gear 65 is meshed with the incomplete gear 63. When in use, the rotator 62 provides driving force for the incomplete gear 63, so that the incomplete gear 63 rotates. The incomplete gear 63 will intermittently mesh with the driven gear 65 during the rotation process, so that the driven gear 65 drives the rotating disk 61 to rotate intermittently through the transmission shaft 64, so that the specimen holder can drive the plant specimen to rotate intermittently, so that different orientations of the plant specimen can stay for a certain period of time when it is turned to the diffusion cover 33, which is convenient for good contact with hot air. In addition, the incomplete gear 63 here can be replaced by a spur gear, and the continuous rotation of the plant specimen can be achieved through the meshing of the spur gear and the driven gear 65, and the plant specimen can also be heated evenly from the circumference.

[0055] See also Figure 5 , Figure 8 and Fig. 9As shown, further, in order to improve the uniformity of heating of plant specimens. An eccentric wheel 11 is also fixedly mounted on the rotating shaft, a push plate 12 is abutted on one side of the eccentric wheel 11, a push rod 13 is fixedly connected to the side of the push plate 12 away from the eccentric wheel 11, and one end of the push rod 13 away from the push plate 12 passes through the drying box 1 and is fixedly connected to the transmission plate 14, and the push rod 13 is located between the transmission plate 14 and the side wall of the drying box 1 and is mounted with a third spring 17, and a pull rod 15 is fixedly connected to each end of the transmission plate 14, and the two pull rods 15 correspond to the two cover bodies 331 one by one, and the end of the pull rod 15 away from the transmission plate 14 passes through and is connected to a sliding plug 16 from the side of the cover body 331 away from the diversion chamber 332, and the sliding plug 16 slides in the cover body 331, and the sliding plug 16 is fixedly connected to each diversion pipe 333 in the cover body 331. Since there is a certain distance between the adjacent jet holes 334 on the shunt pipe 333, the hot air in the local position of the formed hot air layer is relatively thin. At this time, when the rotator is working, it drives the eccentric wheel 11 to rotate. The eccentric wheel 11 cooperates with the push plate 12, the push rod 13, the transmission plate 14 and the third spring 17 to make the transmission plate 14 form a linear reciprocating motion. At this time, the transmission plate 14 drives the corresponding sliding plugs 16 to reciprocate in the diffusion cover 33 and the air collecting cover 34 through two pull rods 15, so that the shunt pipe 333 can swing back and forth in the axial direction, so that the overall flow thickness of the formed hot air layer can be consistent, thereby ensuring that each position of the plant specimen is heated more evenly, the drying effect is better, and it is easy to use.
