Technical Field

[0001] This utility model belongs to the field of pineapple breeding technology, specifically relating to a pineapple breeding tissue culture device. Background Technology

[0002] Pineapple breeding mainly includes two methods: tissue culture propagation and traditional seedling cultivation. Tissue culture propagation uses robust plants of superior varieties, selecting the terminal buds (about 60 days after flowering) with well-shaped and large fruits, and then using shoot tip tissue culture for seedling cultivation. This method has a high propagation coefficient, produces uniform seedlings, and can achieve industrialized production.

[0003] Existing pineapple breeding tissue culture devices involve placing several culture dishes into a base for batch culture. However, the base cannot accommodate culture dishes of different widths and sizes for batch culture. Furthermore, the existing devices cannot adjust the base to different heights as needed, making it inconvenient for researchers to perform operations such as inoculation, observation, sampling, and adding culture medium. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a pineapple breeding tissue culture device, which has the characteristics of being able to place culture dishes of different widths and sizes in batches into the base, and being able to adjust the base to different heights for use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pineapple breeding tissue culture device, comprising a chassis, an air inlet at one end of the chassis, an air outlet at the other end of the chassis, a plurality of culture dishes inside the chassis, handles fixed on both sides of the upper end of the culture dishes, lifting components installed on both sides of the lower end of the chassis, and clamping components inside the chassis.

[0006] The clamping assembly includes a fixing plate, with fixing plates fixed on both sides of the rear end of the chassis. A screw is fixed between the two fixing plates, and a screw cylinder is threaded onto the surface of the screw. A slider is provided on the outside of the screw cylinder, and a clamping rod is fixed to one end of the slider near the chassis. A sliding groove corresponding to the clamping rod is opened at one end of the chassis. Several levers are fixed on the surface of the screw cylinder, and a marking assembly is provided on one side of the upper end of the petri dish.

[0007] Preferably, the marking component includes an erasable plate, which is snapped onto one side of the upper end of the petri dish. A placement groove corresponding to the erasable plate is opened on one side of the upper end of the petri dish. A magnetic block one is snapped onto the lower end of the erasable plate. A magnetic block two is installed in the placement groove at a position corresponding to the magnetic block one. Grooves are opened on both sides of the upper end of the placement groove.

[0008] Preferably, a bearing rotating seat is provided between the screw barrel and the slider, and silicone pads are glued to both ends of the clamping rod.

[0009] Preferably, the end of the lever furthest from the screw cylinder is offset from the side of the chassis, and adjacent levers are at a 45-degree angle to each other.

[0010] Preferably, after the wipeable plate is placed in the placement groove, the side of the wipeable plate fits against the inner wall of the placement groove, and the upper side of the groove is set as an arc-shaped structure.

[0011] Preferably, the lifting assembly includes a base plate, and two base plates are provided on the lower side of the chassis.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a pineapple breeding tissue culture device, including a base plate 1, an air inlet 5 at one end of the base plate 1, an air outlet 7 at the other end of the base plate 1, a plurality of culture dishes 4 inside the base plate 1, handles 6 fixed on both sides of the upper end of the culture dishes 4, lifting components 3 installed on both sides of the lower end of the base plate 1, and clamping components 2 inside the base plate 1.

[0025] The clamping assembly 2 includes a fixing plate 22. The fixing plates 22 are fixed on both sides of the rear end of the base plate 1. A screw 23 is fixed between the two fixing plates 22. A screw cylinder 26 is threadedly connected to the surface of the screw 23. A slider 24 is provided on the outside of the screw cylinder 26. A clamping rod 21 is fixed to one end of the slider 24 near the base plate 1. A groove 25 corresponding to the clamping rod 21 is opened at one end of the base plate 1. Several levers 27 are fixed on the surface of the screw cylinder 26. A marking assembly 28 is provided on one side of the upper end of the petri dish 4.

[0026] Specifically, the marking component 28 includes an erasable plate 281, which is snapped onto one side of the upper end of the petri dish 4. A placement groove 282 corresponding to the erasable plate 281 is formed on one side of the upper end of the petri dish 4. A magnetic block 283 is snapped onto the lower end of the erasable plate 281. A magnetic block 284 is installed in the placement groove 282 at a position corresponding to the magnetic block 283. Grooves 285 are formed on both sides of the upper end of the placement groove 282. By adopting the above technical solution, when performing cultivation work through the petri dish 4, the erasable plate 281 can be marked with a magnetic block 281. The erasable plate 281 is placed in the placement groove 282 at the top of the petri dish 4. The magnetic block 283 at the bottom of the erasable plate 281 is attracted to the magnetic block 284 in the placement groove 282, thereby fixing the erasable plate 281. The experimenter can record the pineapple cultivation status in the corresponding petri dish 4 on the erasable plate 281 without having to use a notebook or other recording tools. This makes it easy to quickly know the cultivation status of the corresponding petri dish 4. At the same time, the groove 285 makes it easy to remove the erasable plate 281 from the placement groove 282.

[0027] Specifically, a bearing rotating seat is provided between the screw barrel 26 and the slider 24, and silicone pads are glued to both ends of the clamping rod 21. By adopting the above technical solution, the screw barrel 26 can rotate in the slider 24, and the silicone pads at both ends of the clamping rod 21 play an anti-slip role and improve the clamping firmness.

[0028] Specifically, the end of the lever 27 away from the screw cylinder 26 is offset from the side of the chassis 1, and adjacent levers 27 are at a 45-degree angle. By adopting the above technical solution, the rotation of the lever 27 is not blocked by the chassis 1, and several levers 27 can be distributed at equal intervals to facilitate the rotation of the lever 27.

[0029] Specifically, after the wipeable plate 281 is placed into the placement groove 282, the side of the wipeable plate 281 fits against the inner wall of the placement groove 282. The upper side of the groove 285 is set with an arc-shaped structure. By adopting the above technical solution, the wipeable plate 281 is more stable in the placement groove 282 after being placed in it. The upper side of the groove 285 is set with an arc-shaped structure to avoid scratching the hands.

[0030] In this embodiment, tissue culture medium is poured into the culture dish 4, and pineapple seeds are placed in it. Then, the culture dish 4 is placed in the base plate 1. At the same time, hot air is introduced into the base plate 1 through the air inlet 5. The temperature of the hot air is adjusted according to the cultivation of the pineapple seedlings so that the pineapple seedlings can be cultivated in a suitable temperature environment.

[0031] After placing culture dishes 4 of different widths into the base plate 1, the screw barrel 26 is rotated by several levers 27 and moved on the screw 23. The movement of the screw barrel 26 drives the slider 24 to move. The movement of the slider 24 can drive one end of the clamping rod 21 to move in the sliding groove 25 of the base plate 1. The clamping rod 21 can clamp and fix the culture dishes 4 placed in the base plate 1. The clamping component 2 is set to facilitate the placement and fixing of culture dishes 4 of different widths into the base plate 1, thereby improving the practicality of the equipment.

[0032] When cultivating pineapple in petri dish 4, the erasable plate 281 is placed in the placement groove 282 at the top of petri dish 4. The first magnetic block 283 at the bottom of the erasable plate 281 is attracted to the second magnetic block 284 in the placement groove 282, thereby fixing the erasable plate 281. The experimenter can record the cultivation status of pineapple in the corresponding petri dish 4 on the erasable plate 281 without having to use a notebook or other recording tools, which makes it easy to quickly know the cultivation status of the corresponding petri dish 4. At the same time, the groove 285 makes it easy to remove the erasable plate 281 from the placement groove 282.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the lifting assembly 3 includes a base plate 31, and two base plates 31 are provided on the lower side of the chassis 1. A support cylinder 32 is fixed to the upper end of the base plate 31, and a sliding plate 34 is slidably connected in the support cylinder 32. The sliding plate 34 is connected to the chassis 1 through a sliding column 33. Fixing bolts 35 are threadedly connected to both sides of one end of the support cylinder 32 at positions corresponding to the sliding column 33. A plurality of fixing holes 36 corresponding to the fixing bolts 35 are opened at one end of the sliding column 33. By adopting the above technical solution, the fixing bolts 35 are inserted through the fixing holes 36 at one end of the sliding column 33. When the 6th component is removed, the chassis 1 can be raised or lowered. The sliding columns 33 on both sides of the lower end of the chassis 1 slide in the support cylinder 32. After the chassis 1 is adjusted to a suitable height, the fixing bolts 35 are screwed into the fixing holes 36 at one end of the sliding column 33 to achieve the effect of limiting and fixing the sliding column 33. The lifting component 3 can be set to adjust the chassis 1 to different heights, which is convenient for experimental personnel to perform operations such as inoculation, observation, sampling, and adding culture medium. It reduces inconvenient movements such as bending over and raising hands during operation, improves work efficiency, and also reduces the labor intensity of operators.

[0035] Specifically, the base plate 31 has through holes on both sides for screws to pass through, and the upper end of the support cylinder 32 has sliding holes on both sides corresponding to the sliding column 33. By adopting the above technical solution, screws can pass through the base plate 31 and be screwed into the reserved installation holes to fix the device, and the sliding column 33 can slide on the upper end of the support cylinder 32.

[0036] In this embodiment, the fixing bolt 35 is removed from the fixing hole 36 at one end of the sliding column 33, which pushes the chassis 1 to rise and fall. The sliding columns 33 on both sides of the lower end of the chassis 1 slide in the support cylinder 32. After the chassis 1 is adjusted to a suitable height, the fixing bolt 35 is screwed into the corresponding fixing hole 36 at one end of the sliding column 33 to achieve the effect of limiting and fixing the sliding column 33. The lifting component 3 can adjust the chassis 1 to different heights, which is convenient for experimental personnel to perform operations such as inoculation, observation, sampling, and adding culture medium. It reduces inconvenient movements such as bending over and raising hands during operation, improves work efficiency, and also reduces the labor intensity of operators.

[0037] The structure and working principle of the base 1, culture dish 4, air inlet 5, handle 6 and air outlet 7 in this utility model have been disclosed in a pineapple breeding tissue culture device disclosed in Chinese Patent Publication No. CN221059154U.

[0038] The working principle and usage process of this utility model are as follows: First, install the device in a suitable position, pour tissue culture solution into the culture dish 4, and put the pineapple seeds into it. Then, place the culture dish 4 into the base plate 1. At the same time, hot air can be introduced into the base plate 1 through the air inlet 5. The temperature of the hot air is adjusted according to the cultivation of the pineapple seedlings so that the pineapple seedlings can be cultivated in a suitable temperature environment.

[0039] After placing culture dishes 4 of different widths into the base plate 1, the screw barrel 26 is rotated by several levers 27 and moved on the screw 23. The movement of the screw barrel 26 drives the slider 24 to move. The movement of the slider 24 can drive one end of the clamping rod 21 to move in the sliding groove 25 of the base plate 1. The clamping rod 21 can clamp and fix the culture dishes 4 placed in the base plate 1. The clamping component 2 is set to facilitate the placement and fixing of culture dishes 4 of different widths into the base plate 1, thereby improving the practicality of the equipment.

[0040] When cultivating pineapple in petri dish 4, the erasable plate 281 is placed in the placement groove 282 at the top of petri dish 4. The first magnetic block 283 at the bottom of the erasable plate 281 is attracted to the second magnetic block 284 in the placement groove 282, thereby fixing the erasable plate 281. The experimenter can record the cultivation status of pineapple in the corresponding petri dish 4 on the erasable plate 281 without having to use a notebook or other recording tools, which makes it easy to quickly know the cultivation status of the corresponding petri dish 4. At the same time, the groove 285 makes it easy to remove the erasable plate 281 from the placement groove 282.

[0041] By removing the fixing bolt 35 from the fixing hole 36 at one end of the sliding column 33, the chassis 1 can be raised and lowered. The sliding columns 33 on both sides of the lower end of the chassis 1 slide in the support cylinder 32. After the chassis 1 is adjusted to a suitable height, the fixing bolt 35 is screwed into the corresponding fixing hole 36 at one end of the sliding column 33 to achieve the effect of limiting and fixing the sliding column 33. The lifting component 3 can adjust the chassis 1 to different heights, which is convenient for experimental personnel to perform operations such as inoculation, observation, sampling, and adding culture medium. It reduces inconvenient movements such as bending over and raising hands during operation, improves work efficiency, and also reduces the labor intensity of operators.
