[0018] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0020] Embodiment 1, as Figures 1 - 14 shown, a tomato leaf miner larva cultivation device according to an embodiment of the present application includes a cultivation cylinder 1 and a cultivation part 3. A central shaft 2 is coaxially arranged in the cultivation cylinder 1. A driving component 11 for providing power to the central shaft 2 is arranged at the bottom inside the cultivation cylinder 1, as Figures 3 - 5 shown. The driving component 11 includes a spring box 111, a driving shaft 112, a spur gear pair 113, a manual rotating shaft 114, and a bevel gear pair 115. The spring box 111 is fixedly connected to the bottom inside the cultivation cylinder 1; one end of the driving shaft 112 is connected to the spring, and the other end of the driving shaft 112 extends out of the spring box 111; the spur gear pair 113 is composed of two meshing gears, and the two gears are respectively fixedly sleeved on the driving shaft 112 and the central shaft 2; the manual rotating shaft 114 is arranged along the radial direction of the cultivation cylinder 1, and one end of it extends out of the cultivation cylinder 1; the bevel gear pair 115 is composed of two meshing bevel gears, and the two bevel gears are respectively sleeved on the driving shaft 112 and the manual rotating shaft 114.

[0021] It can be understood that by rotating the manual rotating shaft 114, the staff can rotate the driving shaft 112 and tighten the spring in the spring box 111. After letting go, under the action of the spring elastic reset, the driving shaft 112 will continue to rotate, so as to drive the central shaft 2 to rotate continuously. The specific rotation time is determined by the spring, and the specific rotation speed can be determined by the sizes of the two gears in the spur gear pair 113. Here, it only needs to be explained that the gear on the driving shaft 112 is smaller than the gear on the central shaft 2, so that the rotation speed of the central shaft 2 can be decreased.

[0022] As Figures 2 - 4 、 Figures 6 - 8As shown in the figure, the cultivation section 3 includes a water storage tank 31, a breeding area 32, a water supply assembly 33, a plurality of connecting pipes 34, and a power assembly 35. The water storage tank 31 is arranged in a ring shape and is used to store part of the water body to provide water source for the breeding area 32. The breeding area 32 covers the top side of the water storage tank 31. The water supply assembly 33 is coaxially sleeved on the central shaft 2. The water supply assembly 33 is divided into a fixed part and a movable part. The fixed part stores water source, and the inner top end of the fixed part is higher than the inner bottom end of the water storage tank 31. The movable part makes an elastic lifting action in the fixed part. A plurality of connecting pipes 34 are circumferentially and evenly communicated with the water supply assembly 33, and the plurality of connecting pipes 34 are respectively communicated with the water storage tank 31, so that the water stored in the fixed part of the water supply assembly 33 can flow into the water storage tank 31. The power assembly 35 includes a passive wedge column 351 connected to the movable part of the water supply assembly 33, and an active wedge column 352 fixedly sleeved on the central shaft 2. The passive wedge column 351 is movably sleeved on the central shaft 2. The central shaft 2 drives the active wedge column 352 to rotate through rotation, and drives the passive wedge column 351 to drive the movable part of the water supply assembly 33 to make a reciprocating lifting action. Through the reciprocating lifting action of the movable part, the water source in the fixed part can enter the interior of the water storage tank 31 through the connecting pipe 34.

[0023] Specifically, the breeding area 32 includes an annular baffle 321, a plurality of connecting bars 322, a fence 323, a plurality of breeding nets 324, a plurality of water suction pipes 325, and a water replenishing pipe 326. The annular baffle 321 is hermetically covered on the top of the water storage tank 31 to prevent the water inside from evaporating, resulting in an accelerated reduction of the water source, and at the same time to prevent the humidity inside the cultivation cylinder 1 from being difficult to control due to water evaporation. The plurality of connecting bars 322 are arranged radially and circumferentially on the inner side of the annular baffle 321 and are movably sleeved on the central shaft 2. It should be noted that, as Figure 4 shown, the design of the connecting bar 322 makes the middle range of the breeding area 32 in a hollow state. The fence 323 is coaxially arranged on the top side of the annular baffle 321 and is movably sleeved on the central shaft 2. The plurality of breeding nets 324 are respectively installed in the fence 323 and abut against the connecting bars 322. The plurality of water suction pipes 325 are circumferentially arranged on the annular baffle 321 and extend into the water storage tank 31. The water replenishing pipe 326 is inserted into the annular baffle 321 and extends into the water storage tank 31 for replenishing the water source.

[0024] It should be noted that, as Figure 4 shown, the periphery of the fence 323 is arranged in a ring shape, and a plurality of straight partitions are radiated inside the ring. The plurality of straight partitions divide the interior of the fence 323 into a plurality of fan-shaped areas, and the plurality of breeding nets 324 are respectively installed in the plurality of fan-shaped areas in one-to-one correspondence.

[0025] It can be understood from this that through the fence 323, a fence can be formed on the periphery of each breeding net 324, preventing the larvae on adjacent breeding nets 324 from "escaping", and improving the observation effect of the larvae on each breeding net 324.

[0026] Further, it should be noted that, as Figure 4 and Figure 8 shown, a capillary water channel 327 is provided on the upper side of the connecting bar 322 for supplying water to the leaves placed on the feeding net 324; a multi-component water diversion channel 328 is provided on the annular baffle 321, and the multi-component water diversion channels 328 respectively correspond to and communicate with a plurality of capillary water channels 327; the water suction pipe 325 is hollow (its bottom end adopts a hollow design, and a detachable end cap is provided at the top end), and it is filled with water-absorbing resin. A plurality of water outlets 329 are distributed in a fan shape on the side wall of the water suction pipe 325 at one end on the top side of the annular baffle 321, and the plurality of water outlets 329 respectively correspond to and communicate with the water diversion channels 328.

[0027] It can be understood therefrom that when the water level in the water storage tank 31 rises to exceed the height of the bottom end of the water suction pipe 325, the water-absorbing resin adsorbs the water body and supplies water to the capillary water channel 327 through the water outlet 329 and the water diversion channel 328. It should be noted that the water outlet 329, the water diversion channel 328, and the capillary water channel 327 all utilize capillary action to achieve water source transmission.

[0028] As Figure 10 shown, the water replenishing pipe 326 is arranged in a double layer. Through holes are provided at the bottom ends of the double layers of the water replenishing pipe 326. The height of the inner layer of the water replenishing pipe 326 is greater than that of the outer layer. A sealing cap is sleeved on the inner layer of the water replenishing pipe 326, and the sealing cap is used to seal the cavity between the inner and outer layers of the water replenishing pipe 326.

[0029] It should be noted that the double-layer design and the design that one layer can be closed are convenient for balancing the internal air pressure in the water storage tank 31 during the water replenishing process.

[0030] Further, it should be noted that the water supply assembly 33 includes a piston cylinder 331, a piston 332, and a plurality of connecting rods 333. The piston cylinder 331 is the fixed end of the water supply assembly 33, and the piston cylinder 331 is movably sleeved on the central shaft 2; the piston 332 is the movable end of the water supply assembly 33 and seals and slides in the piston cylinder 331; a plurality of connecting rods 333 are circumferentially fixed to the piston 332 and seal and slide out of the piston cylinder 331, and the plurality of connecting rods 333 are fixed to the passive wedge-shaped column 351; a spring (not shown in the figure, only for the reset effect of the piston 332, and not limited to only using a spring or the installation position of related components) is sleeved on the connecting rod 333, and the two ends of the spring respectively abut against the piston cylinder 331 and the passive wedge-shaped column 351.

[0031] It should be noted that the end of the passive wedge-shaped column 351 in contact with the active wedge-shaped column 352 has mutually cooperating smooth inclined surfaces.

[0032] It can be understood that when the central shaft 2 rotates driven by the driving component 11, the driving wedge column 352 fixedly sleeved thereon will be driven to rotate. In this way, the driven wedge column 351 will be forced to drive the piston 332 to rise in the piston cylinder 331 through the connecting rod 333. Under the reset action of the spring, the piston 332 will descend after rising to the highest point. In this way, during the continuous rotation of the central shaft 2, the piston 332 will perform reciprocating lifting actions in the piston cylinder 331. Further, it can be understood that when the piston 332 performs reciprocating lifting, the water source in the piston cylinder 331 will cause a tidal phenomenon in the water storage tank 31 through the connecting pipe 34, that is, the water level in the water storage tank 31 will perform repeated lifting actions. In this way, combined with the water suction pipe 325 in the above text, the blades will be intermittently replenished with water to avoid the blades from drying out.

[0033] It should be noted that in the embodiment of the present application, the connecting pipe 34 is arranged in an arc shape. One end of the connecting pipe 34 communicates with the top end of the side wall of the piston cylinder 331, and the other end of the connecting pipe 34 communicates with the bottom end of the side wall of the water storage tank 31.

[0034] It can be understood that when the water body flows in the connecting pipe 34, under the action of the arc-shaped guiding, it will form a certain impact on the water storage tank 31 and the piston cylinder 331 at both ends, avoiding impurities from forming precipitation inside the water storage tank 31 and the piston cylinder 331, and at the same time avoiding blockage caused by precipitation in the connecting pipe 34. Further, after the water body enters the water storage tank 31, due to the action of the arc-shaped connecting pipe 34, the water body rotates in the water storage tank 31 to a certain extent, so as to ensure the water absorption effect at multiple water suction pipes 325 in the water storage tank 31 (to avoid that when the entire cultivation cylinder 1 is tilted at a certain angle, the local water suction pipes 325 cannot absorb water).

[0035] Among them, a boss is provided at the top end of the piston 332, and a plurality of spiral grooves 334 are circumferentially and uniformly arranged on the side wall of the boss. It can be understood that during the lifting process of the piston 332, the spiral grooves 334 cause the water body in the piston cylinder 331 to further rotate, enhancing the flushing effect on the inner wall of the piston cylinder 331 and the piston 332.

[0036] It should be noted that brackets 335 are provided at the bottom sides of the piston cylinder 331 and the water storage tank 31. The brackets 335 are movably sleeved on the central shaft 2. Among them, a plurality of limiting grooves 12 are circumferentially and uniformly arranged on the inner wall of the cultivation cylinder 1, and the brackets 335 are slidably matched with the limiting grooves 12 to facilitate the installation and disassembly of the entire cultivation part 3 in the cultivation cylinder 1.

[0037] Among them, a diversion top 336 is coaxially arranged at the top end of the piston cylinder 331. The diversion top 336 is coaxially and movably sleeved on the central shaft 2. The diversion top 336 is arranged in a conical shape with a smaller top and a larger bottom. It can be understood that this design can prevent the insect feces falling from the top side from accumulating above the piston cylinder 331 and affecting the quality of the internal environment of the entire cultivation cylinder 1.

[0038] The following describes the usage process of a tomato leafminer larva cultivation device according to an embodiment of the present application with reference to the accompanying drawings: When in use, the leaves are respectively placed on a plurality of feeding nets 324, and the larvae are respectively placed on the corresponding leaves. The independent feeding nets 324 form independent feeding spaces, which can prevent the larva density in one feeding space from being too large, resulting in uneven development of the insect bodies and size differences. After placing the larvae, according to observations, when the humidity inside the cultivation cylinder 1 or the humidity of the leaves is insufficient, the staff can rotate the manual rotating shaft 114 to make the central shaft 2 rotate for a certain period of time. By using the rotation of the central shaft 2, the piston 332 reciprocates up and down in the piston cylinder 331 (the lifting speed is controlled by the rotation speed of the central shaft 2, and specific transmission ratio and other related parameters are not elaborated here). Under the upward movement of the piston 332 in the piston cylinder 331, the water body in the piston cylinder 331 enters the water storage tank 31 through the connecting pipe 34. As the piston 332 rises, the water level height in the water storage tank 31 gradually rises and exceeds the height of the bottom end of the water absorption pipe 325. At this time, the water absorption resin in the water absorption pipe 325 adsorbs the water and supplies a certain amount of water to the leaves on the feeding net 324 through capillary action from the water outlet 329 and the water diversion channel 328 into the capillary channel 327. Conversely, when the piston 332 descends, a negative pressure is formed in the piston cylinder 331, causing the water body in the water storage tank 31 to be sucked back into the piston cylinder 331 through the connecting pipe 34. At this time, the water level in the water storage tank 31 drops or even there is no water, and at this time the water absorption pipe 325 cannot supply water to the leaf direction. This design makes the water supply to the leaves form a tidal water supply phenomenon, and the water is supplied from the bottom side of the leaves, avoiding the impact on the insect bodies caused by spraying water from above the leaves, the drastic change of the humidity in the breeding environment, and the cumbersome process of frequent manual spraying.

[0039] In the related art, in the process of raising the larvae of this tomato leafminer larva cultivation device, a large amount of feces will be produced during the growth of the insect bodies. Although the feeding nets 324 and the hollow design in the breeding area 32 are adopted, there will still be a certain amount of feces remaining on the leaves. The remaining feces will breed mold after staying in the breeding environment (with a certain humidity) for a long time, posing a great threat to the healthy growth of the insect bodies and affecting the normal observation of larva cultivation.

[0040] Embodiment 2. According to some embodiments of the present application, such as Figure 2 、 Figure 3 、 Figure 12 and Figure 13As shown in the figure, a diversion part 4 is further arranged in the cultivation cylinder 1. The diversion part 4 includes a spiral slideway 41 and a vibration part. The spiral slideway 41 is coaxially arranged at the bottom side of the cultivation part 3 and is used to guide the worm feces falling from the cultivation part 3 to a specified direction; the vibration part is coaxially arranged at the top of the cultivation part 3 and is used to provide regular vibration to the cultivation part 3.

[0041] Specifically, side baffles 411 are arranged on both sides of the spiral slideway 41. The radial range of the spiral slideway 41 covers the cultivation range of the cultivation area 32. The side baffles 411 are used to prevent the worm feces from bouncing when falling on the spiral slideway 41, thereby preventing the worm feces from falling to a non-specified position at the inner bottom of the cultivation cylinder 1.

[0042] Specifically, a plurality of positioning rings 412 are axially arranged on the circumferential side of the spiral slideway 41. The plurality of positioning rings 412 are in limiting sliding fit with the inner wall of the cultivation cylinder 1, and positioning bars 413 are fixedly connected between the positioning rings 412 and the spiral slideway 41.

[0043] It should be noted that the vibration part includes a sleeve ring 42, a rotating ring 43 and a plurality of elastic rods 44. The sleeve ring 42 is coaxially and fixedly connected to the top end of the enclosure 323. A plurality of extension plates 421 are evenly and fixedly connected to the circumferential side of the sleeve ring 42. The plurality of extension plates 421 are distributed along the straight partition plates on the inner side of the enclosure 323 and correspond to the straight partition plates one by one; the rotating ring 43 is coaxially and fixedly connected to the central shaft 2; the plurality of elastic rods 44 are in damping sliding plug connection with the rotating ring 43. The elastic rods 44 are arranged along the axial direction of the rotating ring 43 and are in elastic contact with the extension plates 421.

[0044] It can be understood that in the present application, since the elastic rod 44 and the rotating ring 43 are in a damping sliding relationship, the axial position of the elastic rod 44 on the rotating ring 43 can be adjusted. Further, it can be understood that when the bottom end height of the elastic rod 44 decreases, the elastic impact force between it and the extension plate 421 is greater, and vice versa.

[0045] It should be noted that in the specific embodiment of the present application, a partition plate is arranged above the spring box 111 at the inner bottom of the cultivation cylinder 1. A collection bucket 14 is slidably arranged on the partition plate, and a side pull door 15 is arranged on the side wall of the cultivation cylinder 1. The collection bucket 14 can be taken out from the side pull door 15. The collection bucket 14 is located below the outlet end of the spiral slideway 41 and is used to collect the guided worm feces.

[0046] Thus, during specific use, the rotation of the central shaft 2 will also synchronously drive the synchronous rotation of the rotating ring 43. In this way, contact will occur between the multiple elastic rods 44 thereon and the extension plate 421. That is, when the elastic rods 44 follow the rotation, they will deform due to the obstruction of the extension plate 421. As the rotation continues, the bottom end of the deformed elastic rod 44 will slip out from the gap between the rotating ring 43 and the extension plate 421 and reset. Under the action of reset and rotation, it will impact the side wall of the next extension plate 421, so that knocking will be formed at the collar 42 and transmitted to the breeding net 324 through the enclosure 323, causing the leaves thereon to vibrate. In this way, the possible residual insect feces on the leaves and the breeding net 324 will be reduced. Of course, the specific radial position and axial length of the elastic rod 44 on the rotating ring 43 can be adaptively changed to form irregular vibrations, avoiding the phenomenon of resonance causing the amplitude to increase and harming the larvae. The fallen insect feces will be guided by the spiral chute 41 and slide down into the collection bucket 14 below. The staff can regularly open the side sliding door 15 to clean the dirt in the collection bucket 14.

[0047] In the related art, for this tomato leaf miner larva cultivation device, because the leaves need to be replenished with water in the breeding environment, a certain humidity will be present in the breeding environment. If the humidity exceeds the safety value, it will cause the leaves to breed mold and affect the health of the larvae. However, if the humidity drops severely in order to remove moisture, it will lead to frequent leaf watering and waste of water resources.

[0048] Example three, according to some embodiments of the present application, as Figure 2 、 Figure 3 and Figure 14 shown, a ventilation part 5 is also provided inside and at the top of the cultivation cylinder 1. The ventilation part 5 includes a diversion cylinder 51, which is coaxially installed inside the spiral chute 41, and its axial two ends respectively extend out of the top and bottom sides of the spiral chute 41; an air flow guiding component 52 is circumferentially distributed on the periphery of the cultivation cylinder 1, and the air flow guiding component 52 connects the water storage tank 31 and the diversion cylinder 51; an air outlet end 53 is arranged at the top of the cultivation cylinder 1.

[0049] Specifically, the air flow guiding component 52 includes a plurality of diversion pipes 521 and a floating ring 522. One ends of the plurality of diversion pipes 521 are inserted into the annular baffle 321, and the other ends of the plurality of diversion pipes 521 extend to the inner bottom of the diversion cylinder 51; the floating ring 522 is sealed and limited to slide in the water storage tank 31 to prevent the floating ring 522 from descending to the bottom of the water storage tank 31; a water suction pipe 325 and a water replenishing pipe 326 are respectively sealed and slidably inserted into the floating ring 522.

[0050] Specifically, a cylinder cap 13 is provided at the top of the cultivation cylinder 1, and an installation groove 131 is provided on the cylinder cap 13; the air outlet end 53 includes an axial center fixing block 531, a plurality of support bars 532, a plurality of bottom side blades 533 and a plurality of top side blades 534. The axial center fixing block 531 is coaxially installed in the installation groove 131; the plurality of support bars 532 are circumferentially and uniformly fixed to the axial center fixing block 531, and the plurality of support bars 532 are installed in the installation groove 131; the plurality of bottom side blades 533 are circumferentially and uniformly arranged in the installation groove 131, and one end of the bottom side blade 533 rotates on the side wall of the installation groove 131, and the other end of the bottom side blade 533 is rotatably connected to the side wall of the axial center fixing block 531; the plurality of top side blades 534 are circumferentially and uniformly arranged in the installation groove 131, and one end of the top side blade 534 rotates on the side wall of the installation groove 131, and the other end of the bottom side blade 533 is rotatably connected to the side wall of the axial center fixing block 531; the plurality of bottom side blades 533 and the plurality of top side blades 534 are matched one by one, and the top side blade 534 is pressed against the bottom side blade 533.

[0051] It should be noted that only partial areas of the top side blade 534 and the bottom side blade 533 overlap during the pressing action.

[0052] Furthermore, it should be noted that when the top side blade 534 is pressed against the bottom side blade 533, there is a gap between the two to ensure the normal air (oxygen content) required for breeding inside the cultivation cylinder 1.

[0053] Thus, during specific use, when the piston 332 rises in the piston cylinder 331, at this time, water surges into the water storage tank 31. As the water level rises, the floating ring 522 rises in the water storage tank 31. At this time, the air inside the water storage tank 31 above the floating ring 522 is compressed and forms an air current through the diversion pipe 521 and surges to the bottom of the diversion cylinder 51. The air current is guided by the diversion cylinder 51 and gushes out from the top, that is, below the piston cylinder 331. Under the action of air pressure conservation, the air current will pass through the hollow range in the middle of the breeding area 32, that is, at the breeding net 324, and then surge to the top of the cultivation cylinder 1, causing the originally pressed top side blade 534 and bottom side blade 533 to rotate and form an open state. The air current gushes out from here to the outside. On the contrary, when the piston 332 descends, a negative pressure will be formed in the water storage tank 31, causing external air to be inhaled into the interior of the cultivation cylinder 1 and transported to the interior of the water storage tank 31 through the diversion pipe 521. At this time, the top side blade 534 and the bottom side blade 533 form a press connection (but not sealed). This design will cause an air current to form inside the entire cultivation cylinder 1 and achieve a ventilation effect inside the cultivation cylinder 1, ensuring the freshness and humidity of the air inside the cultivation cylinder 1, and reducing negative conditions such as the formation of mold in the cultivation environment that are unfavorable for the growth of larvae.

[0054] For the convenience of observation and the normal cultivation of larvae, some components such as the cultivation cylinder 1, the water storage tank 31, the connecting pipe 34, and the piston cylinder 331 can be made of transparent materials to facilitate the irradiation of light and the observation of the water storage capacity.

[0055] It should be noted that the specific model specifications of the spring box 111, the spur gear pair 113, the bevel gear pair 115, the piston 332, and the elastic rod 44 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0056] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
