[0040] Example 1

[0041] like Figure 1-14As shown, a preferred embodiment of this utility model provides a greenhouse cultivation device comprising: two first support plates 1, two second support plates 2, a first shaft 101, a second shaft 201, a connecting plate 102, multiple first cultivation racks 3, multiple second cultivation racks 4, a sliding plate 16, a shell 5, a moving structure, and an unfolding structure; the two first support plates 1 are connected by the first shaft 101, and the two second support plates 2 are connected by the second shaft 201; the first support plates 1 and second support plates 2 located on the same side are connected by the connecting plate 102; the first shaft 101 and the second shaft 201 pass through the connecting plate 102 and are rotatably connected to the connecting plate 102; the multiple first cultivation racks 3 are respectively arranged between the two first support plates 1. The second cultivation rack 4 is located between the two second support plates 2 and inside the first cultivation rack 3. The bottom of the second cultivation rack 4 has multiple openings, and the second cultivation rack 4 communicates with the first cultivation rack 3 through the openings. The sliding plate 16 is connected to the outer wall of the second cultivation rack 4. The inner wall of the first cultivation rack 3 has a sliding groove 310 that matches the sliding plate 16. The sliding groove 310 slides in contact with the sliding plate 16. The housing 5 is fixedly connected to the first cultivation rack 3. The moving structure is located inside the housing 5. The housing 5 includes a housing body, a slide rail 501, and a sealing plate 502. The sealing plate 502 is located on the top of the housing body, and the slide rail 501 is fixedly connected to the sealing plate 502 along the length direction. The movable structure is fixedly connected to the second cultivation rack 4, and the movable structure drives the second cultivation rack 4 to move left and right relative to the first cultivation rack 3. It can be understood that when the second cultivation rack moves a certain distance, the positioning frame can be completely pulled out of the positioning slot, causing the bottom of the positioning frame to detach from the second positioning block. This facilitates the complete detachment of the second cultivation rack from the first cultivation rack, making it convenient to replace the soil on the second cultivation rack. The unfolding structure is fixedly connected between the first support plate 1 and the second support plate 2 on the same side, and is also fixedly connected to the connecting plate 102. The unfolding structure is used to support the first support plate 1 and the second support plate 2. Repeated use of the soil inside the second cultivation rack can lead to nutrient loss. The user can activate the moving structure. Since the moving structure is fixedly connected to the second cultivation rack, when the moving structure moves, it can move the second cultivation rack left and right relative to the first cultivation rack. When the second cultivation rack moves to a certain distance, simply pull the positioning frame completely out of the positioning slot. This will cause the bottom of the positioning frame to detach from the second positioning block, making it easy to completely detach the second cultivation rack from the first cultivation rack. This makes it convenient to replace the soil in the second cultivation rack.

[0042] Example 2

[0043] like Figure 1-14As shown, a preferred embodiment of this utility model provides a greenhouse cultivation device. The first cultivation frame 3 includes: a limiting rod 301, a spring 303, a slider 304, a push plate 305, a clamping plate 306, a buckle 307, and an inclined plate 308. The slider 304 is located at the bottom of the first cultivation frame 3 and has a first through hole. One end of the limiting rod 301 passes through the first through hole and connects to the first support plate 1 or the second support plate 2. The baffle 305 and the spring 303 are both located at the other end of the limiting rod 301. 03 is connected to the limiting rod 301 via a support base. The baffle 305 is fixedly connected to the end of the limiting rod 301. The locking plate 306 is rotatably connected to the baffle 305.

[0044] Preferably, the first cultivation rack 3 further includes a retaining ring 302, which is sleeved on the limiting rod 301. The retaining ring 302 is located at the connection between the limiting rod 301 and the first support plate 1, or at the connection between the limiting rod 301 and the second support plate 2. The limiting rod 301 is pushed by the spring 303, at which point the other end of the limiting rod 301 can pass through the limiting hole. Therefore, the first support plate 1 and the second support plate 2 can support the first cultivation rack 3. When the push plate 305 is pushed to one side, the push plate 305 can move the limiting rod 301 to one side, so that the other end of the limiting rod 301 can disengage from the limiting hole. Then, the locking plate 306 and the buckle 307, which are rotatably connected at the bottom of the push plate 305, are connected, thus preventing the limiting rod 301 from being inserted into the limiting hole again. The first cultivation rack 3 can then swing downwards along the first support plate 1 and the second support plate 2, allowing for the storage of the first cultivation rack 3 that is not currently being planted.

[0045] Preferably, the first cultivation rack further includes a drain pipe 309, which is connected to the drain outlet. When watering the plants cultivated inside the second cultivation rack 4, the water will be discharged into the first cultivation rack 3 through the drain hole, and the water can be guided by the inclined plate 308. The first cultivation rack 3 is connected to the drain pipe 309 through three pipes on its exterior. Therefore, the water guided by the inclined plate 308 will enter the drain pipe 309 through the three pipes for discharge.

[0046] The movable structure includes: a movable frame 503, a first positioning block 504, a second positioning block 505, and a positioning frame.

[0047] 506, threaded screw 507, motor 508, the second positioning block 505 is welded to the top of the second cultivation rack 4, the top of the movable frame 503 is provided with a positioning groove 5034, the positioning groove 5034 extends to the top of the first positioning block 504, the positioning frame 506 passes through the positioning groove 5034, the movable frame 503 is provided with a threaded hole, the threaded screw 507 passes through the threaded hole and is connected to the output end of the motor 508, the motor 508 is fixedly connected to the bottom of the housing 5 by a fixing plate, and the motor 508 drives the movable frame 503 to move through the threaded screw 507.

[0048] Preferably, the movable structure further includes two stabilizing rods 509 and a stabilizing frame 5033, wherein the stabilizing frame 5033

[0049] The stabilizer 5033 is fixedly connected to the bottom of the movable frame 503. The stabilizer 5033 has two second through holes, through which the two stabilizer rods 509 pass.

[0050] Preferably, the movable frame 503 includes a set of first pulleys 5031 and a set of second pulleys 5032.

[0051] The first pulley 5031 and the second pulley 5032 are fixedly connected to the movable frame 503 by a shaft. The shaft of the first pulley 5031 is in the horizontal direction, and the shaft of the second pulley 5032 is in the vertical direction. The first pulley 5031 slides in contact with the slide rail 501. A movable groove is provided inside the housing body, and the second pulley 5032 slides in contact with the movable groove.

[0052] When the motor 508 is powered on, it drives the lead screw 507 inside the housing 5 to rotate. Since the internal thread through the right side of the movable frame 503 engages with the external thread of the lead screw 507, the movable frame 503 can move to one side along the lead screw 507. The top of the movable frame 503 corresponds to the second positioning block 505 via the first positioning block 504, and the positioning slot 5034 allows the positioning frame 506 to pass through the second positioning block 505. The movable frame 503 can then drive the second cultivation rack 4 to slide inside the first positioning frame 506. The sliding grooves 310 on the two inner sides of the second cultivation rack 4 are slidably connected to the sliding plate 16, thus allowing the second cultivation rack 4 to slide within the first positioning plate 506. Plate 16 helps reduce friction between the second cultivation rack 4 and the inside of the first cultivation rack 3. The stabilizing rod 509 inside the shell 5 is connected to the bottom of the movable rack 503 through the stabilizing frame 5033. When the movable rack 503 moves along the screw 507, it helps increase the stability of the movable rack 503. A set of moving grooves is opened on both inner sides of the shell 5, and a second pulley 5032 is slidably connected inside each set of moving grooves. At this time, the second pulley 5032 can reduce friction between the movable rack 503 and the inside of the shell 5 when it moves. A set of slide rails 501 are slidably connected to the first pulley 5031 respectively. The first pulley 5031 helps to drive the second cultivation rack 4 to move.

[0053] Preferably, the unfolding structure specifically includes: a first connecting block 6, a first swing plate 7, a second swing plate 8, a second connecting block 9, a third swing plate 10, a fourth swing plate 11, two third shafts 12, a moving plate 13, an insert block 14, and a screw 15. The first connecting block 6 and the second connecting block 9 are respectively connected to the hidden grooves opened in the first support plate 1 and the second support plate 2. One end of the first swing plate 7 and one end of the second swing plate 8 are respectively rotatably connected to both sides of the first connecting block 6, and the other end of the first swing plate 7 and the other end of the second swing plate 8 are rotatably connected to the moving plate 13; the third swing plate... One end of the third swing plate 10 and one end of the fourth swing plate 11 are rotatably connected to the two sides of the second connecting block 9, respectively. The other end of the third swing plate 10 and the other end of the fourth swing plate 11 are rotatably connected to the moving plate 13. The third shaft 12 is fixedly connected to the connecting plate 102. The moving plate 13 has a through hole and is sleeved on the third shaft 12 through the through hole. The insert 14 is welded between the two third shafts 12. The bottom of the moving plate 13 has a slot. The insert 14 has a threaded through hole and is threadedly connected to the insert 14 through the threaded through hole.

[0054] At this time, a set of first support plates 1 and a set of second support plates 2 can be unfolded through the connecting plate 102. When the first support plate 1 and the second support plate 2 are unfolded, the movable plate 13 can move downward along the third shaft 12. Therefore, the movable plate 13 can make the first swing plate 7, the second swing plate 8, the third swing plate 10 and the fourth swing plate 11 move downward through the first connecting block 6 and the second connecting block 7 respectively, which is beneficial to support the first support plate 1 and the second support plate 2.

[0055] The movable plate 13 has a slot at its bottom, and the inside of the slot is wrapped around the outside of the insert block 14. The bottom of the insert block 14 is threadedly connected to a screw 15, and the top of the screw 15 passes through the inside of the movable plate 13. At this time, the slot at the bottom of the movable plate 13 can be inserted into the insert block 14. Therefore, the insert block 14 supports the movable plate 13, thereby preventing the first support plate 1 and the second support plate 2 from shaking significantly. By rotating the screw 15, the screw 15 is spirally screwed into the insert block 14 and passes through the inside of the movable plate 13. At this time, the insert block 14 can be fixed inside the movable plate 13.

[0056] In this embodiment, repeated use of the soil for the crops planted inside the second cultivation rack leads to nutrient loss, thus activating the motor. The motor drives the lead screw to rotate inside the housing. The internal thread penetrating the right side of the moving frame engages with the lead screw thread, allowing the moving frame to move along the outside of the lead screw. The top of the first positioning block has a positioning groove through which the positioning frame passes through the second positioning block. The moving frame then slides along the lead screw inside the first cultivation rack. Sliding grooves are provided on both sides of the inside of the first cultivation rack, and the inside of these grooves is connected to the outside of the second cultivation rack via a sliding plate. The sliding plate reduces friction between the second cultivation rack and the first cultivation rack. When the second cultivation rack has moved a certain distance, the positioning frame can be completely pulled out of the positioning groove, causing the bottom of the positioning frame to detach from the second positioning block. This facilitates the complete separation of the second cultivation rack from the first cultivation rack, making it convenient to replace the soil in the second cultivation rack.

[0057] Example 3

[0058] According to an embodiment of this utility model, a greenhouse cultivation device has a plurality of ball bearings embedded in the inner wall of the through hole of the movable plate 13, and the ball bearings are in rolling contact with the third shaft 12. When the movable plate 13 moves downward, the embedded ball bearings facilitate the sliding of the movable plate 13 along the third shaft 12, reducing friction.

[0059] The working process of this utility model is as follows: Repeated use of the soil for crops planted inside the second cultivation frame 4 leads to nutrient loss, thus activating the motor 508. The motor 508 drives the lead screw 507 to rotate inside the housing 5. A set of moving slots is provided on both sides of the housing 5. Both sides of the moving frame 503 are slidably connected to the moving slots via a set of second pulleys 5032. The internal thread penetrating the right side of the moving frame 503 is threadedly engaged with the lead screw 507, allowing the moving frame 503 to move along the lead screw 507. At this time, the moving frame 503 can drive the second pulleys 5032 to slide inside the housing 5, thereby reducing the friction between the moving frame 503 and the housing 5. A first pulley 5031 is slidably connected to the top of the housing 5 via a set of slide rails 501. The second pulleys 5032 can increase the movement... The stability of the moving frame 503 is ensured by the positioning groove 5034 at the top of the first positioning block 504, which allows the positioning frame 506 to pass through the interior of the second positioning block 505. At this time, the moving frame 503 can drive the second cultivation frame 4 to slide inside the first cultivation frame 3 along the screw 507. The first cultivation frame 3 has sliding grooves 310 on both sides inside. The interior of the sliding grooves 310 is connected to the exterior of the second cultivation frame 4 through the sliding plate 16. Through the action of the sliding plate 16, the friction between the second cultivation frame 4 and the first cultivation frame 3 can be reduced. When the second cultivation frame 4 moves to a certain distance, the positioning frame 506 can be completely pulled out of the positioning groove 5034, so that the bottom of the positioning frame 506 will be separated from the interior of the second positioning block 505. Therefore, it is convenient to completely separate the second cultivation frame 4 from the interior of the first cultivation frame 3, which makes it convenient to replace the soil in the second cultivation frame 4.

[0060] In summary, this utility model embodiment provides a greenhouse planting device. When the motor is started, it drives a lead screw to rotate inside the housing. A set of movable slots is provided on both sides of the housing. Both sides of the movable frame are slidably connected to the movable slots via a set of second pulleys. The internal thread penetrating the right side of the movable frame is screwed into the lead screw thread, allowing the movable frame to move along the lead screw. At this time, the movable frame can drive the second pulleys to slide inside the housing, thereby reducing the friction between the movable frame and the housing. A first pulley is slidably connected to the top of the housing 5 via a set of slide rails, and the second pulleys increase the stability of the movable frame's movement. The positioning frame can be inserted through the positioning groove at the top of the first positioning block into the interior of the second positioning block. At this time, the moving frame can drive the second cultivation frame to slide inside the first cultivation frame along the screw. Sliding grooves are opened on both sides inside the first cultivation frame. The interior of the sliding grooves is connected to the exterior of the second cultivation frame through a sliding plate. Through the action of the sliding plate, the friction between the second cultivation frame and the first cultivation frame can be reduced. When the second cultivation frame moves to a certain distance, the positioning frame can be completely pulled out of the positioning groove. Thus, the bottom of the positioning frame will be separated from the interior of the second positioning block 5, making it convenient to completely separate the second cultivation frame from the interior of the first cultivation frame. This makes it convenient to replace the soil in the second cultivation frame.
