Description

Technical Field

[0001] The invention relates to the technical field of bamboo shoot specimen preparation, in particular to a bamboo shoot specimen preservation tube and a preservation method. Background Art

[0002] Traditionally, the preparation of bamboo shoot specimens adopts the method of preparing plant wax leaf specimens, that is, after the specimens are pressed, dried and disinfected, they are sewn on professional paper. The bamboo shoot specimens prepared in this way are often deformed or even burst due to repeated binding and pressing, and some important structures such as sheaths, sheath ears and epidermal hairs are seriously damaged. Moreover, due to the relatively long preparation process, important information such as the surface color, spots and patches of the bamboo shoot sheath are also severely damaged. Secondly, the bamboo shoots themselves not only have a high water content, but also are rich in nutrients such as sugar and protein. If the drying is not timely and thorough, it is easy to mildew, be eaten by insects and even rot. In addition, the water content of each part of the bamboo shoot is different. The upper end of the bamboo shoot is tender and has a high water content. The existing bamboo shoot specimen preparation process does not take into account the different water contents of the various parts of the bamboo shoots, which makes it easy for the prepared bamboo shoot specimens to be partially over-dried or partially under-dried. Summary of the invention

[0003] The invention provides a bamboo shoot specimen preservation tube and a preservation method, aiming to solve the problems of easy deformation, serious damage and uneven drying in the preparation process of bamboo shoot specimens proposed in the background art.

[0004] In order to achieve the above-mentioned purpose, according to a first aspect of the present invention, the present invention provides the following technical solutions: a bamboo shoot specimen preservation tube, comprising a bottom cover, a first sleeve being threadedly connected to the inner surface of the bottom cover, a first partition being installed in the middle of the inner wall of the first sleeve, a first limiting hole being opened in the middle of the first partition, the first limiting hole being used for the middle of the bamboo shoot to pass through, a first through groove being symmetrically arranged at the edge of the first partition, a second sleeve being threadedly connected to the upper inner wall of the first sleeve, the bottom end of the second sleeve being against the upper surface of the first partition, a third sleeve being threadedly connected to the inner wall of the top end of the second sleeve, a second partition being installed inside the second sleeve, a second limiting hole being opened in the middle of the second partition, the second limiting hole being used for the upper end of the bamboo shoot to pass through, the bottom end of the third sleeve being against the second partition, and a top cover being threadedly connected to the top end of the third sleeve.

[0005] It can be seen from the above technical scheme that the present invention, through the mutual cooperation of the first sleeve, the second sleeve, the third sleeve, the first partition, the second partition, the first through groove, the second through groove, the first limiting hole and the second limiting hole, makes the storage device divided into independent spaces along the height direction of the bamboo shoots, which is convenient for putting in desiccants of different particle sizes. Since the upper end of the bamboo shoots is tender and has a high water content, small-particle desiccants are stored correspondingly, and the small-particle desiccant is compact, so that the desiccant corresponding to the upper end of the bamboo shoots has a stronger water absorption capacity, while the lower end of the bamboo shoots corresponds to the storage of large-particle desiccant, so that the desiccant corresponding to the lower end of the bamboo shoots is sparse, and the water absorption capacity is adapted to the water content of the lower end of the bamboo shoots, which is conducive to uniform drying of various parts of the bamboo shoots; at the same time, the bamboo shoot specimen drying device does not need to repeatedly tie and press the bamboo shoots, so that the bamboo shoots will not be deformed or even burst, and will not cause serious damage to important structures of the bamboo shoots such as sheaths, sheath ears and epidermal hairs.

[0006] A further solution is that the bottom end of the second sleeve blocks the first through slot, so that the desiccant in the first sleeve cannot enter the second sleeve, and the desiccant in the second sleeve cannot enter the first sleeve. The bottom end of the third sleeve blocks the second through slot, so that the desiccant in the third sleeve cannot enter the second sleeve, and the desiccant in the second sleeve cannot enter the third sleeve.

[0007] It can be seen from the above technical scheme that the present invention respectively opens the first through groove, the second through groove, the first adapter hole and the second adapter hole at the edges of the first partition and the second partition, so that the side walls of the second sleeve and the third sleeve can respectively cover the first through groove, the first adapter hole, the second through groove and the second adapter hole, thereby avoiding the desiccant in the first sleeve, the second sleeve and the third sleeve from mixing together, which is beneficial to the uniform drying of various parts of the bamboo shoots. At the same time, compared with opening a feeding port on the side walls of the first sleeve, the second sleeve and the third sleeve, the present invention does not need to additionally set up a blocking piece, that is, the side walls of the first sleeve, the second sleeve and the third sleeve of the present invention not only play the role of accommodating the desiccant, but also play the role of blocking the feeding port, thereby omitting the need to set up a blocking piece and simplifying the structure of the preservation tube.

[0008] A further solution is that the outer surface of the first partition is threadedly connected to the inner wall of the first sleeve, the outer surface of the second partition is threadedly connected to the inner wall of the second sleeve, a first adapter hole is opened at the edge of the first partition, and a second adapter hole is opened at the edge of the second partition, the shapes of the first adapter hole and the second adapter hole are both polygonal, a fixing block is installed on the outer surface of the first sleeve, an operating rod is inserted on the fixing block, and the cross-sectional shape of the operating rod is adapted to the first adapter hole and the second adapter hole.

[0009] It can be seen from the above technical solution that since the cross-section of the bamboo shoots from the top to the bottom is conical, the present invention threadedly connects the first partition and the second partition to the first sleeve and the second sleeve, and under the action of the operating rod, the first partition and the second partition can move up and down in the first sleeve and the second sleeve, so that the first partition and the second partition can adapt to bamboo shoots of different sizes. When bamboo shoots of different sizes are placed in the preservation tube, it can be ensured that the desiccant in the third sleeve will not enter the second sleeve from the second limiting hole, and the desiccant in the second sleeve will not enter the first sleeve from the first limiting hole, further avoiding the desiccant in the first sleeve, the second sleeve and the third sleeve from mixing together, so that the preservation tube of the present invention is suitable for bamboo shoots of different sizes, thereby improving the applicability of the preservation tube.

[0010] A further solution is that the operating rod is L-shaped, and a handle is provided at the end of the operating rod.

[0011] A further solution is that the bottom cover, the first sleeve, the second sleeve, the third sleeve and the top cover are all made of acrylic tube.

[0012] A further solution is that the first adapting holes are symmetrically distributed around the first partition.

[0013] A further solution is that the second adapting holes are symmetrically distributed around the second partition.

[0014] According to a second aspect of the present invention, a method for preserving bamboo shoot specimens is provided, which specifically comprises:

[0015] Hollow out the inside of the bamboo shoots and open up all the joints;

[0016] After the top of the bamboo shoots passes through the first partition, the bamboo shoots are placed in the first sleeve, and then the bottom cover is threadedly connected to the bottom end of the first sleeve, and then the operating rod is inserted into the first adapter hole, and the operating rod is rotated to make the first partition move up and down, so that the first partition fits the outer surface of the bamboo shoots, and then the bottom cover is removed from the first sleeve, and the desiccant is filled into the inner cavity of the bamboo shoots. After the filling is completed, the bottom cover is threadedly connected to the bottom end of the first sleeve again;

[0017] Adding a large-diameter granular desiccant into the first sleeve through the first through slot on the first partition plate;

[0018] The second sleeve is placed in the first sleeve, and the second sleeve is rotated until the bottom end of the second sleeve is against the first partition; then the operating rod is inserted into the second adapter hole, and the operating rod is rotated to make the second partition move up and down, so that the second partition fits the outer surface of the bamboo shoots;

[0019] Adding granular desiccant into the second sleeve through the second through slot on the second partition plate, wherein the particle size of the desiccant in the second sleeve is smaller than the particle size of the desiccant in the first sleeve;

[0020] Place the third sleeve in the second sleeve, and rotate the third sleeve until the bottom end of the third sleeve abuts against the second partition;

[0021] Adding granular desiccant into the third casing, wherein the particle size of the desiccant in the third casing is smaller than the particle size of the desiccant in the second casing;

[0022] Thread the top cap onto the top of the third sleeve.

[0023] In a further embodiment, the desiccant is a silica gel particle desiccant.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention divides the storage device into independent spaces along the height direction of the bamboo shoots through the mutual cooperation of the first sleeve, the second sleeve, the third sleeve, the first partition, the second partition, the first through groove, the second through groove, the first limiting hole and the second limiting hole, so that the storage device is divided into independent spaces along the height direction of the bamboo shoots, which is convenient for putting in desiccants of different particle sizes. Since the upper end of the bamboo shoots is tender and has a high water content, small-diameter desiccants are stored correspondingly, and the small-diameter desiccants are compact, so that the desiccant corresponding to the upper end of the bamboo shoots has a stronger water absorption capacity, and the desiccant corresponding to the lower end of the bamboo shoots is stored correspondingly with large-diameter desiccant, so that the lower end of the bamboo shoots is more The corresponding desiccant is sparse, and the water absorption capacity is adapted to the water content of the lower end of the bamboo shoots, which is conducive to uniform drying of all parts of the bamboo shoots; at the same time, the bamboo shoot specimen drying device does not need to repeatedly bind and press the bamboo shoots, so that the bamboo shoots will not be deformed or even burst, and will not cause serious damage to important structures of the bamboo shoots such as sheaths, sheath ears and epidermal hairs; the present invention respectively opens the first through groove, the second through groove, the first adapting hole and the second adapting hole at the edges of the first partition and the second partition, so that the side walls of the second sleeve and the third sleeve can respectively cover the first through groove, the first adapting hole, the second through groove and the second adapting hole, thereby avoiding the first The desiccant in the sleeve, the second sleeve and the third sleeve is mixed together, which is conducive to uniform drying of various parts of the bamboo shoots. At the same time, compared with the feeding port provided on the side walls of the first sleeve, the second sleeve and the third sleeve, the present invention does not need to set up an additional blocking piece, that is, the side walls of the first sleeve, the second sleeve and the third sleeve of the present invention not only play the role of accommodating the desiccant, but also play the role of blocking the feeding port, thereby omitting the need to set up a blocking piece and simplifying the structure of the storage tube; since the cross-section of the bamboo shoot from the top to the bottom is conical, the present invention is achieved by threading the first partition plate and the second partition plate on the first sleeve and the second sleeve Under the action of the operating rod, the first partition and the second partition can move up and down in the first sleeve and the second sleeve, so that the first partition and the second partition are adapted to bamboo shoots of different sizes.

DETAILED DESCRIPTION

[0030] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Example 1

[0034] See also Figure 1 to Figure 3The present invention provides a bamboo shoot specimen storage tube, comprising a bottom cover 1, wherein the inner surface of the bottom cover 1 is threadedly connected with a first sleeve 2, wherein a first partition 6 is installed in the middle of the inner wall of the first sleeve 2, wherein a first limiting hole 10 is provided in the middle of the first partition 6, and the first limiting hole 10 is used for the middle of the bamboo shoot 12 to pass through. It can be understood that, in such a configuration, after the bottom cover 1 is removed from the bottom end of the first sleeve 2, the bamboo shoot 12 is hollowed out, and all joints are opened. After the first sleeve 2 is inverted, the bamboo shoot 12 is placed on the first partition 6, so as to facilitate the filling of desiccant into the bamboo shoot 12. Since the bamboo shoot 12 specimen is to display its external form to people, hollowing out the inside of the bamboo shoot 12 will not affect the preparation of the bamboo shoot 12 specimen, and is conducive to the full drying of the bamboo shoot 12. The first through groove 8 is symmetrically arranged at the edge of the first partition 6, and the first through groove 8 is used to add a large-particle desiccant into the first sleeve 2. The second sleeve 3 is threadedly connected to the inner wall of the upper part of the first sleeve 2, the bottom end of the second sleeve 3 is against the upper surface of the first partition 6, the third sleeve 4 is threadedly connected to the inner wall of the upper end of the second sleeve 3, a second partition 7 is installed inside the second sleeve 3, a second limiting hole 11 is opened in the middle of the second partition 7, and second through grooves 9 are symmetrically arranged at the edge of the second partition 7, and the second through grooves 9 are used to add larger particle size desiccant into the second sleeve 3.

[0035] The second limiting hole 11 is used for the upper end of the bamboo shoot 12 to pass through, the bottom end of the third sleeve 4 is against the second partition 7, and the top end of the third sleeve 4 is threadedly connected with a top cover 5. After opening the top cover 5, it is convenient to add a small-particle desiccant into the third sleeve 4.

[0036] In some embodiments, the outer surface of the first partition 6 is threadedly connected to the inner wall of the first sleeve 2, and the outer surface of the second partition 7 is threadedly connected to the inner wall of the second sleeve 3. A first adapter hole 15 is opened at the edge of the first partition 6, and a second adapter hole 16 is opened at the edge of the second partition 7. The shapes of the first adapter hole 15 and the second adapter hole 16 are both polygonal, and in this embodiment, they are regular quadrilaterals. A fixing block 14 is installed on the outer surface of the first sleeve 2, and an operating rod 13 is inserted on the fixing block 14. The cross-sectional shape of the operating rod 13 is adapted to the first adapter hole 15 and the second adapter hole 16. It can be understood that when bamboo shoots of different sizes are placed in the preservation tube, if the first partition 6 and the second partition 7 are welded to the first sleeve 2 and the second sleeve 3 respectively, then for bamboo shoots of different sizes, there will inevitably be a relatively large gap with the inner walls of the first limiting hole 10 and the second limiting hole 11, so that the desiccant in the third sleeve 4 enters the second sleeve 3 from the second limiting hole 11, and the desiccant in the second sleeve 3 enters the first sleeve 2 from the first limiting hole 10; causing desiccant of different particle sizes to mix together, so that the desiccant has no desiccant mixed with the desiccant in different parts of the bamboo shoots. The amount of water is adapted, and the present invention threadably connects the first partition 6 and the second partition 7 to the first sleeve 2 and the second sleeve 3. Under the action of the operating rod 13, the first partition 6 and the second partition 7 can move up and down in the first sleeve 2 and the second sleeve 3, so that the first partition 6 and the second partition 7 can adapt to bamboo shoots of different sizes, avoiding the desiccant in the first sleeve 2, the second sleeve 3 and the third sleeve 4 from mixing together through the first limiting hole 10 and the second limiting hole 11, so that the storage tube of the present invention is suitable for bamboo shoots of different sizes, thereby improving the applicability of the storage tube.

[0037] In some embodiments, the operating rod 13 can be set as a variable diameter rod, and the cross-sectional size of the operating rod 13 gradually decreases from the upper end to the lower end. At this time, the fixing block 14 is installed at the lower end of the first sleeve 2. When the operating rod 13 is inserted into the first adapter hole 15 or the second adapter hole 16, the operating rod 13 will not slide downward and poke the bamboo shoots 12.

[0038] Furthermore, the bottom end of the second sleeve 3 blocks the first through groove 8 and the first adapting hole 15 , so that the desiccant in the first sleeve 2 cannot enter the second sleeve 3 , and the desiccant in the second sleeve 3 cannot enter the first sleeve 2 .

[0039] Furthermore, the bottom end of the third sleeve 4 blocks the second through groove 9 and the second adapting hole 16 , so that the desiccant in the third sleeve 4 cannot enter the second sleeve 3 , and the desiccant in the second sleeve 3 cannot enter the third sleeve 4 .

[0040] In this embodiment, the desiccant is silica gel.

[0041] The bottom cover 1, the first sleeve 2, the second sleeve 3, the third sleeve 4 and the top cover 5 are all made of acrylic tube.
