Description

Technical Field

[0001] This utility model relates to the field of fern spore sowing technology, specifically to a fern spore sowing device. Background Technology

[0002] The spores of *Adiantum capillus-veneris* are tiny, only 5-20 μm in size, and difficult to see with the naked eye. If dried spore powder is directly sown, it is easily affected by airflow disturbances or gravity, leading to uneven distribution on the substrate surface, missed or repeated sowing, and consequently, uneven germination. To precisely control the germination environment and improve the initial survival rate, in practice, the spores should be prepared into a suspension with sterile water, and then sown using tools such as pipettes, pipettes, syringes, or spray bottles to ensure uniform coverage of the substrate surface.

[0003] As per existing technology, patent CN210183858U discloses a spore-sowing device, comprising a tube for holding a spore suspension, a spraying structure with adjustable spray holes, and a squeezing structure for pushing the spore suspension in the tube to the spraying structure. The spraying structure is located at one end of the tube, and the squeezing structure is connected to the tube. The spraying structure includes a first spraying layer with multiple first through holes and a second spraying layer located below the first spraying layer and having multiple adjustable second through holes that overlap or partially overlap with the first through holes. The first spraying layer and the second spraying layer are rotatably or slidably connected. The tube is connected to the first through holes. This spore-sowing device effectively reduces spore loss, allows adjustment of the spray hole diameter according to spore size, is universally applicable, and ensures extremely uniform distribution of the spore suspension, which is beneficial for later spore growth.

[0004] The aforementioned sowing device still has certain drawbacks: although it can distribute the spore suspension evenly, which is beneficial for later spore growth, filling the spore suspension is quite difficult; the spray assembly of this sowing device is detachable, requiring manual disassembly to re-absorb the spore suspension after each spraying operation. While this method ensures reliable suspension absorption, the frequent disassembly and reassembly not only increases the operator's physical exertion but also significantly prolongs the time required for each operation, making it extremely inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a fern spore sowing device that makes it simpler and more convenient to extract spore suspension.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fern spore sowing device, comprising a cylinder, a piston mechanism, a connecting pipe, and a spraying mechanism. An outer ring is fixedly connected to the outer side of the lower end of the cylinder, and a water inlet pipe is fixedly connected to one side of the outer ring. An inner ring is rotatably connected to the inner side of the lower end of the cylinder. A lower connecting hole is provided at the bottom of the inner ring, and a side connecting hole is provided on the side wall of the inner ring.

[0007] Furthermore, the outer wall of the upper end of the inner ring is fitted with a sealing sleeve that is fixedly connected to the cylinder body, and the outer rings of the lower connecting hole and the side connecting hole are both fitted with sealing elements, which are fixedly connected to the outer wall of the inner ring.

[0008] Furthermore, the water inlet pipe and the two connecting pipes are on the same straight line, and the position of the side connecting hole is on the vertical line corresponding to the line connecting the two lower connecting holes.

[0009] Furthermore, a lever is fixed to the outer wall of the inner ring, one side of the lever abuts against one end of the outer ring, and the angle between the other side of the lever and the end of the outer ring is 90°.

[0010] Furthermore, a permanent magnet is fixed to the middle position of the lever, and iron sheets are fixed to both ends of the outer ring.

[0011] Furthermore, a rotating ring is fixedly connected to both the upper and lower ends of the inner ring, and the cross-section of the rotating ring is trapezoidal.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This fern spore-sowing device is simple and convenient to operate. After the spore suspension inside the cylinder is sprayed, simply rotate the inner ring to misalign the lower connecting hole with the connecting tube and align the side connecting hole with the water inlet pipe. Then, insert the end of the water inlet pipe away from the cylinder into the spore suspension and pull the piston mechanism to draw the external spore suspension into the cylinder. After the suction is complete, simply rotate the inner ring in the opposite direction to realign the lower connecting hole with the connecting tube. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-6 A fern spore sowing device includes a cylinder 1, a piston mechanism 2, a connecting pipe 3, and a spraying mechanism 4. An outer ring 5 is fixedly connected to the outer side of the lower end of the cylinder 1, and a water inlet pipe 6 is fixedly connected to one side of the outer ring 5. An inner ring 8 is rotatably connected to the inner side of the lower end of the cylinder 1. A lower connecting hole 10 is opened at the bottom of the inner ring 8, and a side connecting hole 11 is opened on the side wall of the inner ring 8.

[0023] In this utility model, after the spore suspension inside the cylinder 1 has been sprayed, simply rotate the inner ring 8 to displace the lower connecting hole 10 from the connecting pipe 3 and align the side connecting hole 11 with the water inlet pipe 6. Then, insert the end of the water inlet pipe 6 away from the cylinder 1 into the spore suspension and pull the piston mechanism 2 to draw the external spore suspension into the cylinder 1. After the suction is complete, simply rotate the inner ring 8 in the opposite direction to realign the lower connecting hole 10 with the connecting pipe 3. At this time, the side connecting hole 11 will be displaced from the water inlet pipe 6 again, and then the piston mechanism 2 can be pushed to sow the spores. The entire process does not require disassembly of the spraying mechanism 4, making the operation simple and convenient. In addition, the structure of the cylinder 1, piston mechanism 2, connecting pipe 3, and spraying mechanism 4 in this utility model is similar to the structure of a spore sowing device disclosed in the prior art patent with patent authorization announcement number CN210183858U, so it will not be described in detail here.

[0024] like Figures 3 to 6 As shown, the outer wall of the upper end of the inner ring 8 is fitted with a sealing sleeve 15 that is fixedly connected to the cylinder 1, and the outer rings of the lower connecting hole 10 and the side connecting hole 11 are both fitted with sealing elements 12, which are fixedly connected to the outer wall of the inner ring 8.

[0025] Specifically, the inner ring 8 is sealed and protected by the sealing sleeve 15 and the sealing element 12 to prevent water leakage; in addition, the sealing sleeve 15 and the sealing element 12 can be made of elastic materials such as rubber or silicone.

[0026] like Figure 4 As shown, the water inlet pipe 6 and the two connecting pipes 3 are on the same straight line, and the position of the side connecting hole 11 is on the vertical line corresponding to the line connecting the two lower connecting holes 10.

[0027] like Figure 2 and Figure 3 As shown, a lever 13 is fixed to the outer wall of the inner ring 8. One side of the lever 13 abuts against one end of the outer ring 5, and the angle between the other side of the lever 13 and the end of the outer ring 5 is 90°.

[0028] Specifically, since the side connection hole 11 is located on the vertical line of the line connecting the two lower connection holes 10, and the water inlet pipe 6 and the two connecting pipes 3 are on the same straight line, when the lower connection hole 10 is aligned with the connecting pipe 3, the angle between the water inlet pipe 6 and the side connection hole 11 will be exactly 90°. Therefore, after the inner ring 8 is rotated 90° by the lever 13, the side connection hole 11 will be aligned with the water inlet pipe 6. Since the angle between the other side of the lever 13 and the end of the outer ring 5 is 90°, the lever 13 will not be pushed too far when it is pushed.

[0029] like Figure 3 As shown, a permanent magnet 14 is fixedly connected to the middle position of the dial block 13, and iron sheets 7 are fixedly connected to both ends of the outer ring 5.

[0030] Specifically, after the push block 13 abuts against one end of the outer ring 5, the iron plate 7 will attract the permanent magnet 14, thereby restricting the push block 13 and preventing the push block 13 from moving on its own.

[0031] like Figure 6 As shown, a rotating ring 9 is fixed to both the upper and lower ends of the inner ring 8, and the cross-section of the rotating ring 9 is trapezoidal.

[0032] Specifically, the inner ring 8 is rotatably connected to the cylinder 1 via the rotating ring 9, and the trapezoidal rotating ring 9 can prevent the inner ring 8 from detaching from the cylinder 1; in addition, the rotating ring 9 can be made of materials with self-lubricating properties such as polytetrafluoroethylene or polyoxymethylene, which makes the rotation between the inner ring 8 and the cylinder 1 smoother.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
