Description

Technical Field

[0001] The invention belongs to the technical field of cabbage cultivation, and in particular relates to an organic cabbage cultivation device and method. Background Art

[0002] In the field of organic cabbage cultivation, seedling transplanting is a widely used and effective cultivation method. Currently, traditional organic cabbage seedlings are mostly carried out in the seedling cavity of the seedling bed, and the seedlings are cultivated in the soil layer of the seedling cavity.

[0003] However, during transplanting, the soil may stick to the inner wall of the seedling chamber, making it difficult to remove the seedlings. Forcibly removing the seedlings will cause many problems, such as: the roots are easily pulled off, affecting the water absorption capacity; the stems (especially the base of the elongated seedling stems) are easily broken or torn, destroying the material transportation channel, etc. These problems seriously affect the survival rate of seedling transplanting and the cultivation quality. Summary of the Invention

[0004] The present invention provides an organic cabbage cultivation device and method, which aims to solve the problem raised in the above background technology that seedlings are difficult to remove due to adhesion of soil to the inner wall of the seedling chamber, which in turn easily causes root breakage and stem damage, thereby affecting the survival rate of seedling transplantation and cultivation quality.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the description of the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The embodiment of the present invention provides an organic cabbage cultivation device and method, such as Figure 1-12 As shown, the organic cabbage cultivation device includes: a box body 1 and a seedling tray 2 for growing cabbage seedlings that is slidably arranged in the box body 1; a support net 3 arranged in the seedling cavity of the seedling tray 2; a connecting box 4 fixedly installed at the bottom of the seedling tray 2; a threaded cylinder 6 fixedly installed at the bottom of the support net 3 and sliding through the bottom of the seedling tray 2; a threaded rod 5 rotatably installed in the connecting box 4 for driving the threaded cylinder 6 and the support net 3 to slide and separate the soil from the seedling cavity; a height adjustment mechanism arranged on the box body 1 and the seedling tray 2 for adjusting the height of the seedling tray 2; a transmission mechanism arranged on the connecting box 4 and the seedling tray 2 for driving the threaded rod 5 to rotate; and an escape-proof net 28 arranged on the seedling tray 2 for preventing beneficial insects in the seedling cavity from escaping.

[0022] In this embodiment, cabbage is organically grown in the seedling cavity of the seedling tray 2. In order to prevent seedling diseases and pests, beneficial insects (such as ladybugs, lacewings, etc.) are poured into the escape-proof net 28. These beneficial insects will not feed on the cabbage plants, but will prey on pests on the cabbage (such as aphids, whiteflies, cabbage worm larvae, etc.) to achieve biological control. In addition, before seed seedlings are grown, the soil level needs to be lower than the seedling cavity to facilitate the subsequent separation of the soil and the seedling cavity.

[0023] When the seedlings need to be transplanted, the height adjustment mechanism is started to drive the seedling tray 2 to slide up. At the same time, the transmission mechanism operates synchronously. During the sliding process of the seedling tray 2, the support net 3 in the seedling chamber will also slide up at the same time, pushing the soil up, so that the soil is separated from the inner wall of the seedling chamber. When transplanting, the seedlings and the soil can be taken out more conveniently; the soil is pushed up by the sliding of the support net 3, so that the soil is separated from the inner wall of the seedling chamber, which effectively solves the problem of the soil adhering to the inner wall of the seedling chamber during traditional seedling transplanting, making it difficult to take out the seedlings, and the problem of forced removal easily breaking the roots, breaking or tearing the stems, thereby improving the survival rate of seedling transplanting and the cultivation quality. By setting the anti-escape net 28 and pouring beneficial insects into it, the beneficial insects are used to prey on pests to achieve biological control, reduce the use of chemical pesticides, meet the requirements of organic planting, and ensure the quality and safety of cabbage.

[0024] In a further preferred embodiment of the present invention, the height adjustment mechanism includes: a vertical plate 7 fixedly mounted on the top of the box body 1; a rotating drum 8 rotatably mounted on one side of the vertical plate 7; a guide wheel 9 fixedly mounted on the vertical plate 7; a pull rope 10 fixedly mounted on the rotating drum 8 for pulling the seedling tray 2 up and down, the pull rope 10 passing around the guide wheel 9 and fixedly connected to the seedling tray 2; a first driven gear 11 fixedly mounted on the rotating shaft of the rotating drum 8; a hydraulic cylinder 12 fixedly mounted on one side of the vertical plate 7; and a first rack 13 fixedly mounted on the hydraulic cylinder 12 for driving the first driven gear 11 and the rotating drum 8 to rotate.

[0025] The first rack 13 is driven by the hydraulic cylinder 12 to move, thereby driving the first driven gear 11 and the rotating drum 8 to rotate, and the pull rope 10 is used to pull the seedling tray 2 up, thereby realizing the adjustment of the height of the seedling tray 2.

[0026] In a further preferred embodiment of the present invention, a guide groove 14 is formed on one side of the first rack 13 , and a guide block 15 is fixedly mounted on one side of the vertical plate 7 , and the guide block 15 is slidably connected to the guide groove 14 .

[0027] In this embodiment, the sliding connection structure between the guide block 15 and the guide groove 14 can effectively limit the moving direction of the first rack 13, preventing it from offsetting or shaking during movement, thereby ensuring the stability of the movement of the first rack 13, thereby making the operation of the entire height adjustment mechanism more stable and reliable.

[0028] In a further preferred embodiment of the present invention, the transmission mechanism includes: a second driven gear 16 rotatably mounted on one side of the connecting box 4, the rotating shaft of the second driven gear 16 extending into the connecting box 4; a group of bevel differential gears 17 fixedly mounted on the rotating shaft of the second driven gear 16 and the threaded rod 5, respectively, and a group of the bevel differential gears 17 are meshed with each other; a second rack 18 fixedly mounted on the bottom of the inner wall of the box body 1 and meshing with the second driven gear 16.

[0029] In this embodiment, when the height adjustment mechanism drives the seedling tray 2 to slide up, the second driven gear 16 will rotate along the second rack 18. The rotation of the second driven gear 16 will drive the bevel differential gear 17 on its rotating shaft to rotate, and then drive the bevel differential gear 17 on the threaded rod 5 to rotate through the meshing relationship, so that the threaded rod 5 rotates. When the threaded rod 5 rotates, the threaded cylinder 6 will rise along the threaded rod 5, thereby driving the support net 3 to rise, pushing the soil up, and separating the soil from the inner wall of the seedling cavity. The transmission mechanism realizes the synchronous linkage between the height adjustment mechanism and the support net 3. While the height adjustment mechanism drives the seedling tray 2 to slide up, the support net 3 automatically rises through a series of gear transmissions, without the need for additional operating steps, thereby improving the efficiency of the transplanting operation and simplifying the operating process.

[0030] In a further preferred embodiment of the present invention, a limit plate 19 is fixedly installed on one side of the seedling chamber, and an inclined plate 20 is fixedly installed on the top of the support net 3, and the inclined plate 20 is covered on the limit plate 19.

[0031] In this embodiment, the support net 3 drives the inclined plate 20 to slide when it rises, and the inclined plate 20 slides along the inner wall of the seedling chamber. When the support net 3 contacts the limit plate 19, the support net 3 stops sliding up. At the same time, the second driven gear 16 disengages from the second rack 18, and the support net 3 is stabilized in the stop position, ensuring that the support net 3 stops rising after pushing the soil and the inner wall of the seedling chamber to an appropriate degree of separation, avoiding damage to the seedlings or the device caused by excessive rising of the support net 3, and improving the safety and reliability of the transplanting operation.

[0032] In a further preferred embodiment of the present invention, a water guide groove 21 is provided at the bottom of the seedling tray 2, and the water guide groove 21 is connected to a group of longitudinal seedling cavities of the seedling tray 2. A drainage pipe 22 is fixedly installed on one side of the seedling tray 2, and the drainage pipe 22 is connected to the water guide groove 21. An arc tube 23 is fixedly installed on one side of the box body 1, and the arc tube 23 is located below the drainage pipe 22 and is used to divert the water in the seedling tray 2 out of the box body 1; a water spray pipe 24 for irrigating the seedlings is fixedly installed on the vertical plate 7.

[0033] In this embodiment, during the cabbage seedling raising process, the seedlings are irrigated by a water spray pipe 24 fixedly installed on the vertical plate 7. Since the support net 3 is water permeable, excess water during irrigation will penetrate through the support net 3 into the water guide groove 21 opened at the bottom of the seedling tray 2. The water guide groove 21 is connected to a group of longitudinal seedling cavities of the seedling tray 2, and can collect excess water seeping from each seedling cavity. The water will flow out through the drain pipe 22, and the water flowing out of the drain pipe 22 will be discharged outside the box 1 along the arc pipe 23, thereby avoiding excessive water accumulation in the seedling tray 2 to affect the growth of the seedlings.

[0034] In a further preferred embodiment of the present invention, a limiting rod 25 is fixedly installed on the top of the inner wall of the box body 1, and a limiting block 26 for guiding and limiting the seedling tray 2 is fixedly installed on the limiting rod 25, and the limiting block 26 is fixedly connected to the seedling tray 2.

[0035] In this embodiment, when the height adjustment mechanism drives the seedling tray 2 to move up and down, the limit block 26 will slide along the limit rod 25 as the seedling tray 2 moves, providing a guide for the movement of the seedling tray 2, ensuring that the seedling tray 2 can move smoothly in a predetermined direction without deviation or shaking.

[0036] In a further preferred embodiment of the present invention, an anti-escape frame 27 is fixedly sleeved on the seedling tray 2, and the anti-escape frame 27 is slidably connected to the connecting piece of the anti-escape net 28. The top of the anti-escape net 28 is hinged with a cover 29 for placing beneficial insects, and a rod 30 is inserted into one side of the anti-escape frame 27, and the rod 30 is connected to the connecting piece that slides through the anti-escape net 28.

[0037] In this embodiment, during the cultivation of cabbage seedlings, the connecting piece of the anti-escape net 28 is inserted into the slot of the anti-escape frame 27, and then the insertion rod 30 is inserted into one side of the anti-escape frame 27, so that the insertion rod 30 slides through the connecting piece of the anti-escape net 28, thereby firmly mounting the anti-escape net 28 on the anti-escape frame 27. At this time, the anti-escape frame 27 and the anti-escape net 28 together form a closed space, which can effectively prevent beneficial insects from escaping; The provision of the insertion rod 30 makes the installation and removal of the anti-escape net 28 very convenient. When the anti-escape net 28 needs to be installed, it is only necessary to connect the connecting piece to the anti-escape frame 27 and then insert the insertion rod 30.

[0038] In a further preferred embodiment of the present invention, a support frame 31 for supporting the seedling tray 2 is fixedly installed on the bottom of the inner wall of the box body 1, and a buffer pad is installed on the top of the support frame 31, and the buffer pad is in close contact with the bottom of the seedling tray 2.

[0039] In this embodiment, since a buffer pad is installed on the top of the support frame 31, and the buffer pad is in close contact with the bottom of the seedling tray 2, when the seedling tray 2 descends, the buffer pad will first contact the seedling tray 2, and absorb the impact force generated when the seedling tray 2 descends through its own elastic deformation, thereby cushioning the seedling tray 2 and preventing the seedling tray 2 from directly colliding with the bottom of the inner wall of the box body 1. The setting of the buffer pad can effectively reduce the impact force generated by the seedling tray 2 colliding with the bottom of the inner wall of the box body 1 when the seedling tray 2 descends, preventing the seedling tray 2 from being damaged by the collision, and also avoiding damage to the cabbage seedlings in the seedling tray 2 due to the collision, thereby ensuring the growth environment of the seedlings and the integrity of the seedling tray 2, which is conducive to the healthy growth of the cabbage seedlings.

[0040] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, the anti-escape net 28 is provided with a feeding mechanism for adding beneficial insect feed to the seedling cavity, and the feeding mechanism includes: a storage box 32 fixedly mounted on the top of the anti-escape net 28 for storing feed; a rotating rod 33 rotatably mounted in the anti-escape net 28; a cylinder 34 fixedly mounted on the rotating rod 33, and a fan-shaped feeding trough is provided on the cylinder 34; and a handle 38 fixedly mounted at one end of the rotating rod 33 for rotating the rotating rod 33.

[0041] In this embodiment, after the beneficial insects have eaten the pests, in order to prevent the beneficial insects from dying, beneficial insect feed needs to be added to the seedling cavity. When adding feed, the operator turns the handle 38 to drive the rotating rod 33 to rotate. The rotation of the rotating rod 33 will drive the cylinder 34 to rotate together, so that the fan-shaped trough of the cylinder 34 is directly opposite the discharge port of the storage box 32. At this time, the feed stored in the storage box 32 will enter the fan-shaped trough through the discharge port. Then, the handle 38 is turned again to make the cylinder 34 continue to rotate, and the feed in the fan-shaped trough will be discharged to the soil below as the cylinder 34 rotates.

[0042] The sprockets 35 are mounted on the cam 33 and the chain 37 is engaged with the cam 33 and the limit wheel 36.

[0043] In another embodiment of the present invention, a beneficial insect collection mechanism for collecting beneficial insects is provided on one side of the box body 1, and the beneficial insect collection mechanism includes: a collection cabin 39 fixedly installed on one side of the box body 1; a transparent plate 40 installed in the collection cabin 39, and a partition 41 is fixedly installed on the bottom of the transparent plate 40, and the partition 41 separates the collection cabin 39 into a suction chamber and a habitat chamber; UV-A lamps 42 are respectively installed in the suction chamber and the habitat chamber for attracting beneficial insects; a sealing plate 43 rotatably installed on one side of the collection cabin 39 for sealing the hatch of the collection cabin 39; and an escape prevention mechanism is provided on the collection cabin 39 for preventing beneficial insects from escaping from the collection cabin 39.

[0044] In this embodiment, the night before the cabbage seedlings are grown and need to be transplanted, the height adjustment mechanism is activated to raise the seedling tray 2. Since a notch is provided on one side of the anti-escape frame 27 and the sealing plate 43 on one side of the collecting chamber 39 is usually placed horizontally on the support block (the support block is located below the sealing plate 43, so that the sealing plate 43 is usually in an open state), when the seedling tray 2 is raised, the notch is directly opposite the hatch of the collecting chamber 39. At the same time, the UV-A lamps 42 in the attraction chamber and the habitat chamber are turned on at the same time. The light emitted by the UV-A lamps 42 has an attractive effect on beneficial insects. At night, the beneficial insects are attracted by the UV-A lamps 42 and enter the collection chamber 39 through the gap in the anti-escape frame 27. The next day, the anti-escape net 28 is removed. At this time, the beneficial insects have been collected in the collection chamber 39 and will not affect the transplanting of the cabbage seedlings. The anti-escape mechanism provided on the collection chamber 39 can prevent the beneficial insects from escaping from the collection chamber 39 during the collection process. By utilizing the attraction characteristics of the UV-A lamp 42 for beneficial insects, the beneficial insects are collected at night when they are more active. The seedling tray 2 is raised by the height adjustment mechanism so that the gap of the anti-escape frame 27 is opposite to the hatch of the collection cabin 39, providing a channel for the beneficial insects to enter the collection cabin 39. The beneficial insects can be efficiently collected in the collection cabin 39, avoiding the loss of beneficial insects during the transplanting process, and facilitating the subsequent unified treatment or reuse of the beneficial insects.

[0045] In another embodiment of the present invention, the escape prevention mechanism includes: a placement groove 44 provided in the habitat chamber for placing food to attract beneficial insects to return actively; the placement groove 44 is located on one side of the UV-A lamp 42; an escape prevention plate 45 fixedly installed in the habitat chamber, the escape prevention plate 45 is arranged in an inclined shape, and a filter sponge 46 is placed on the partition net of the escape prevention plate 45; a suction hopper 48 fixedly installed at the bottom of the escape prevention plate 45 and covered on the partition net; a vacuum pump 47 installed at the bottom of the habitat chamber for sucking beneficial insects onto the filter sponge 46 to prevent them from escaping, and the air inlet end of the vacuum pump 47 is fixedly connected to the suction hopper 48; and a controller 53 installed on one side of the collection cabin 39.

[0046] In this embodiment, when the beneficial insect collection operation is performed at night, the UV-A lamp 42 and the vacuum pump 47 are turned on synchronously. The light emitted by the UV-A lamp 42 attracts the beneficial insects into the collection chamber 39. Since the partition 41 at the bottom of the transparent plate 40 blocks the light of the UV-A lamp 42 located in the attraction chamber, the beneficial insects entering the collection chamber 39 are mainly attracted by the light of the UV-A lamp 42 located in the habitat chamber.

[0047] At the same time, when the vacuum pump 47 is turned on, the partition net on the anti-escape plate 45 generates suction. For beneficial insects that can fly (such as ladybugs, lacewings, etc.), the suction on the partition net will adsorb the beneficial insects to the filter sponge 46 placed on the partition net, restricting the beneficial insects from taking off and preventing them from escaping. Since a placement groove 44 is provided at the bottom of the habitat chamber, food (such as artificial honeydew, aphid eggs) or sex pheromones that the beneficial insects like can be placed in the placement groove 44. After the beneficial insects are adsorbed on the filter sponge 46, they will be further attracted by these attractants and actively crawl towards the placement groove 44, further reducing the possibility of the beneficial insects escaping. During the day, when the seedlings need to be transplanted, the operator rotates the sealing plate 43 away from the support block. At this time, the sealing plate 43 is attracted to the magnet block 49 located at the hatch of the collection chamber 39, fixing the sealing plate 43, thereby sealing the hatch of the collection chamber 39. After that, the vacuum pump 47 and the UV-A lamp 42 can be turned off to carry out the subsequent transplanting operation. The beneficial insects are adsorbed on the filter sponge 46 by the suction force generated by the vacuum pump 47, limiting their ability to fly. At the same time, the food or sex pheromone placed in the placement groove 44 is used to attract the beneficial insects to actively crawl towards the placement groove 44. The beneficial insects are protected from escape from both physical restriction and chemical attraction, which greatly improves the success rate of beneficial insect collection and reduces the number of beneficial insects that escape during the collection process. The light of the UV-A lamp 42 in the attraction chamber is blocked by the partition 41, so that the beneficial insects are mainly attracted by the light of the UV-A lamp 42 in the habitat chamber, guiding the beneficial insects into the habitat chamber, facilitating subsequent escape prevention and collection operations, and improving the efficiency of beneficial insect collection. The controller 53 installed on one side of the collection cabin 39 realizes intelligent management of the beneficial insect collection process and height adjustment of the seedling tray 2, thereby improving the convenience of operation.

[0048] In another embodiment of the present invention, a support plate 51 is slidably installed in the connecting plate 50 of the anti-escape net 28, and the support plate 51 contacts the bottom of the seedling tray 2. An L-shaped rod 52 is fixedly installed on the top of the support net 3, and the L-shaped rod 52 is fixedly connected to the support plate 51.

[0049] In this embodiment, when beneficial insects need to be collected (the night before transplanting), the threaded rod 5 drives the threaded cylinder 6 to slide upward, and the threaded cylinder 6 drives the support net 3 to slide upward synchronously. Since there is an L-shaped rod 52 on the top of the support net 3, and the L-shaped rod 52 is connected to the support plate 51, when the support net 3 slides upward, the L-shaped rod 52 also slides upward synchronously, thereby driving the support plate 51 to slide in the connecting plate 50 of the anti-escape net 28; As the support plate 51 slides, it will move into the groove of the connecting plate 50. At this time, the opening at the bottom of the connecting plate 50 that was originally blocked by the support plate 51 is exposed, so that the upper parts of a group of longitudinal seedling chambers are connected to each other. At the same time, this opening is connected to the notch on the anti-escape frame 27, providing a channel for beneficial insects to return to the collection cabin 39. At night, the UV-A lamp 42 is turned on to attract beneficial insects, and the beneficial insects can smoothly return to the collection cabin 39 through this connected channel. By utilizing the linkage relationship between the threaded rod 5, the threaded cylinder 6, the support net 3, the L-shaped rod 52 and the support plate 51, the channel between the seedling chambers is automatically opened when needed, without the need for additional manual operation, and the structure is simple.

[0050] The present invention also provides a cultivation method for organic cabbage cultivation, comprising the following steps: Step 1: Fill the seedling cavity of the seedling tray 2 with soil, lower than the cavity to allow for separation, and then sow the seeds. After sowing, insert the connecting piece of the escape prevention net 28 into the slot of the escape prevention frame 27 and secure it with the insertion rod 30 to prevent the beneficial insects from escaping. To release the beneficial insects, open the top cover 29 of the escape prevention net 28 and pour in the beneficial insects (such as ladybugs and lacewings). The beneficial insects prey on cabbage pests (such as aphids, whiteflies, and cabbage worm larvae), achieving biological control.

[0051] Step 2: During irrigation, water the cabbage seedlings through the spray pipe 24 on the vertical plate 7. Excess water seeps through the support net 3 into the water guide 21 at the bottom of the seedling tray 2. The water is collected by the water guide 21 and then discharged from the box 1 through the drain pipe 22 and the arc pipe 23 to prevent water accumulation from affecting the growth of the seedlings.

[0052] Step 3: After the beneficial insects have consumed the pests, feed is added to prevent their death. Turning handle 38 rotates the rotating rod 33 and cylinder 34, so that the fan-shaped trough of cylinder 34 faces the discharge port of storage box 32, and the feed enters the fan-shaped trough. Turning handle 38 again causes the feed in the fan-shaped trough to be discharged onto the soil as cylinder 34 rotates.

[0053] Step 4: Before transplanting the seedlings, start the height adjustment mechanism. The hydraulic cylinder 12 drives the first rack 13 to move, drives the first driven gear 11 to rotate, drives the rotating drum 8 to rotate, and the pull rope 10 is wound around to pull the seedling tray 2 up. At the same time, the second driven gear 16 rotates along the second rack 18, drives the threaded rod 5 to rotate, causes the threaded drum 6 to rise along the threaded rod 5, drives the support net 3 to push the soil upward, and separates the soil from the inner wall of the seedling chamber. While the support net 3 slides up, the L-shaped rod 52 drives the support plate 51 to slide in the connecting plate 50 of the anti-escape net 28, exposing the through opening, so that a group of longitudinal seedling chambers are connected above, and connected with the gap of the anti-escape frame 27, providing a channel for the beneficial insects to return to the collection cabin 39.

[0054] Step 5: Simultaneously with the activation of the height adjustment mechanism, the UV-A lamps 42 in the suction chamber and habitat chamber are turned on to attract the beneficial insects. Simultaneously, the vacuum pump 47 is activated, creating suction on the screens on the escape prevention plate 45, trapping any flying beneficial insects on the filter sponge 46. A holding trough 44 at the bottom of the habitat chamber contains food or pheromones favored by the beneficial insects, attracting them toward the holding trough 44 and reducing their escape potential.

[0055] Step 6: As the support net 3 in the seedling raising cavity slides upward and pushes the soil upward, the soil is separated from the inner wall of the seedling raising cavity. At this time, the seedlings and soil can be taken out more conveniently, thereby improving the survival rate of seedling transplantation and the cultivation quality.

[0056] In summary, compared with related technologies, this device achieves the advantages of effective control of cabbage pests and improved seedling transplanting survival rate and cultivation quality through settings such as biological control, convenient seedling transplanting and efficient collection of beneficial insects.
