[0003] Kiwi fruit greenhouse cultivation requires top and side ventilation. Common greenhouse shapes are generally arched, which makes it easier for heat to accumulate below the ridge line when it rises. In existing technology, the top ventilation openings of the greenhouse are generally located on both sides of the ridge line and the openings are small, which affects the rapid dissipation of heat. Therefore, improvements are needed to address these issues. Summary of the Invention

The positioning slider is threadedly connected to the threaded shaft and slidably connected to the arch frame. The first movable groove is opened at one end of the positioning slider. One end of the spring telescopic rod slides inside the first movable groove. The extension block is fixedly connected to the positioning slider. The second movable groove is opened at one end of the extension block.

[0009] Preferably, the positioning component includes a positioning block and a wedge block, the wedge block being fixedly installed on one side of the positioning block, and the wedge block contacting one end of the inclined surface of the positioning slider.

[0010] Preferably, the guide assembly includes a guide rod and a spring.

This solves the problems of fixed ventilation area and low heat dissipation efficiency in traditional greenhouses. The ventilation volume can be adjusted in real time according to the temperature and humidity inside the greenhouse, significantly improving the flexibility and accuracy of greenhouse environmental control.

[0016] This invention, through the cooperation of a dual-axis motor, a first gear, a second gear, and a top rod, can drive the top rod to complete a large-angle directional flip, quickly changing the tilt angle of the greenhouse roof film. This allows snow on the roof to slide down quickly along the tilted roof surface by gravity, achieving contactless and convenient snow removal from the greenhouse roof. This solves the problems of high risk and low efficiency of traditional manual snow removal operations in greenhouses, avoids damage to the greenhouse structure from snow overload, and improves the greenhouse's disaster resistance and service life.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, the present invention provides an easily adjustable planting greenhouse, including a column 100, and further comprising: Arch frame 200, which is erected between two sets of columns 100; Angle steel 300 is provided between column 100 and arch frame 200 and adjacent arch frame 200, and is used to fix arch frame 200. Activity mechanism 400 is mounted on arch frame 200; Adjustment mechanism 500 is disposed on arch frame 200 and located on the side of movable mechanism 400. Adjustment mechanism 500 is used to lock movable mechanism 400. Drive mechanism 600 is mounted on arch frame 200 and is used to drive adjustment mechanism 500 and unlock active mechanism 400.

[0021] like Figure 2 As shown, the movable mechanism 400 includes a base rod 410, a connecting assembly 420, and a top plate assembly 430. The connecting assembly 420 is symmetrically rotatably connected to both ends of the base rod 410, and the connecting assembly 420 is rotatably connected to the top plate assembly 430.

[0022] The above scheme is adopted: the bottom rod 410, the top plate assembly 430 and the two connecting components 420 form a quadrilateral structure with hinge points. In the initial state, the two connecting components 420 are respectively limited by two sets of adjustment mechanisms 500. When it is necessary to change the angle of the top plate assembly 430, the positioning block 531 in one set of adjustment mechanisms 500 can be moved to contact the positioning block 531 in the opposite set of adjustment mechanisms 500. At this time, only one set of connecting components 420 is limited, and the other connecting component 420 can cooperate with the bottom rod 410 and the top plate assembly 430 to tilt and flip, thereby realizing the flexible adjustment of the opening and closing angle of the greenhouse top. The rotation direction can also be adjusted according to locking different connecting components 420. It is worth noting that the greenhouse film is installed on the side of the column 100 and the surface of the top plate assembly 430, and the seal between adjacent top plate assemblies 430 and between the column 100 and the top plate assembly 430 can be achieved by installing elastic rubber blocks.

[0023] like Figures 3 to 6As shown, each arch 200 is provided with four symmetrically distributed adjustment mechanisms 500, and the two adjustment mechanisms 500 on the asymmetrical side are staggered. Each adjustment mechanism 500 includes a threaded shaft 510, a pressing assembly 520, a positioning assembly 530, a spring telescopic rod 540, and a guide assembly 550. The threaded shaft 510 is rotatably connected to the arch 200. The pressing assembly 520 is threadedly connected to the surface of the threaded shaft 510 and slidably connected to the arch 200. The positioning assembly 530 is connected to the pressing assembly 520 via the spring telescopic rod 540. 20. The positioning assembly 530 is also elastically slidably connected to the threaded shaft 510 via the guide assembly 550; the extrusion assembly 520 includes a positioning slider 521, a first movable groove 522, an extension block 523, and a second movable groove 524. The positioning slider 521 is threadedly connected to the threaded shaft 510 and slidably connected to the arch frame 200. The first movable groove 522 is opened at one end of the positioning slider 521, and one end of the spring telescopic rod 540 slides inside the first movable groove 522. The extension block 523 is elastically slidably connected to the positioning slider 510 via the guide assembly 550. 21. Fixed connection; the second movable groove 524 is opened at one end of the extension block 523; the positioning assembly 530 includes a positioning block 531 and a wedge block 532, the wedge block 532 is fixedly installed on one side of the positioning block 531, and the wedge block 532 contacts the inclined surface of one end of the positioning slider 521; the guide assembly 550 includes a guide rod 551 and a spring 552, one end of the guide rod 551 is fixedly connected to the positioning block 531, and the other end is movable inside the second movable groove 524, and the spring 552 is sleeved on the guide rod 551. The surface is located between the positioning block 531 and the second movable groove 524. The spring 552 is compressed in the initial locked state. The drive mechanism 600 includes a drive motor 610 and a shaft 620. The drive motor 610 is fixedly installed in the middle of the arch frame 200. The drive motor 610 is connected to the shaft 620 through a helical gear. The shaft 620 is connected to the threaded shaft 510 through a helical gear. Rectangular grooves 411 are opened at the middle of both ends of the first positioning shaft 422. The positioning block 531 is engaged in the rectangular groove 411.

[0024] Using the above scheme: the drive motor 610 drives the threaded shaft 510 to rotate via the shaft 620, thereby causing the extrusion assembly 520 on the threaded shaft 510 to move as a whole towards the other side of the staggered extrusion assemblies 520. During the movement, because the positioning block 531 is locked inside the rectangular groove 411, the movement of the extrusion assembly 520 as a whole will cause the positioning block 531 to move outward along the length direction of the rectangular groove 411 through the cooperation of the positioning slider 521 and the inclined surface of the wedge block 532. Simultaneously, the spring telescopic rod 540 shortens while sliding along the first movable groove 522, and at the same time, the guide rod 551 slides inside the second movable groove 524 and penetrates into the second movable groove 524. The spring 552 is compressed inside the groove 524, and the positioning block 531 is locked inside the rectangular groove 411, thus locking the connecting component 420. Unlocking is achieved by removing the positioning block 531. When both connecting components 420 are locked, the top plate component 430 is fixed in position and will not move under external force. When one connecting component 420 is unlocked, the top plate component 430 can rotate around the hinge axis of the other locked connecting component 420, thereby achieving flexible adjustment of the opening angle of the greenhouse top. By changing the unlocked connecting component 420, the rotation direction of the top plate component 430 also changes. For example, the top plate component 430 located on the left top... Figure 1 When rotated counterclockwise, the middle area of ​​the greenhouse roof can be opened for quick heat dissipation. At the same time, when snow accumulates, the tilt angle can be changed to allow the snow on the surface to slide off, making snow removal faster and more convenient. The top plate assembly 430 located on the left side can open the greenhouse for ventilation and heat dissipation when rotated clockwise, and facilitate snow removal when rotated counterclockwise.

[0025] like Figure 8 As shown, the connecting assembly 420 includes a vertical rod 421, a first positioning shaft 422, a connecting rod 423, a first gear 424, and a dual-axis motor 425. The first positioning shaft 422 and the connecting rod 423 are fixed from top to bottom to the middle of two symmetrically distributed vertical rods 421. The first positioning shaft 422 protrudes from the vertical rod 421 and the protruding part is hinged to the bottom rod 410. The dual-axis motor 425 is fixedly installed in the middle of the connecting rod 423. The first gear 424 is symmetrically fixedly installed on the output shafts on both sides of the dual-axis motor 425. The top plate assembly 430 includes a top rod 431, a second positioning shaft 432, and a second gear 433. Two second positioning shafts 432 are fixedly installed inside the top rod 431. The second gears 433 are symmetrically installed on the surface of the second positioning shafts 432 and mesh with the first gear 424. The second positioning shafts 432 are also hinged to the vertical rod 421.

[0026] Using the above scheme: the first positioning shaft 422 is the hinge shaft between the vertical rod 421 and the bottom rod 410, and the vertical rod 421 and the first positioning shaft 422 are fixedly connected. Rectangular grooves 411 are opened on both sides of the first positioning shaft 422. Therefore, when the positioning block 531 is inserted into the rectangular groove 411, the first positioning shaft 422 is locked and cannot rotate. The vertical rod 421, which is fixedly connected to the first positioning shaft 422, is also fixed. By starting the dual-axis motor 425 located on one side of the fixed first positioning shaft 422, the first gear 424 can drive the second gear 433 to rotate. The rotation of the second gear 433 drives the top plate assembly 430 to rotate as a whole, so as to achieve precise adjustment of the opening of the greenhouse top.

[0027] Working principle and usage process of this invention: During the main structure construction phase of the greenhouse, the columns 100 serve as the base support, and the arch frame 200 is erected between the two sets of columns 100. Angle steel 300 is used to rigidly fix the columns 100 and the arch frame 200, as well as adjacent arch frames 200, thus building a stable load-bearing frame for the greenhouse. The movable mechanism 400 is erected on the arch frame 200 as a whole. The greenhouse film is installed on the side of the columns 100 and the surface of the top plate assembly 430. Elastic rubber blocks are used to seal between adjacent top plate assemblies 430 and between the columns 100 and the top plate assembly 430 to ensure the greenhouse's airtightness. In the initial closed state, both sets of connecting components 420 of the movable mechanism 400 are locked by the corresponding adjustment mechanism 500: the positioning block 531 is engaged in the rectangular groove 411 at the end of the first positioning shaft 422. In the initial locked state, the compressed spring 552 continuously pushes the positioning block 531 with its own elastic force, so that the positioning block 531 is kept in a stable engaged and limited state with the rectangular groove 411. At the same time, the spring telescopic rod 540 cooperates to complete the elastic connection and limitation between the positioning component 530 and the pressing component 520, restricting the rotation of the first positioning shaft 422. The vertical rod 421, which is fixedly connected to the first positioning shaft 422, is simultaneously and completely locked. At this time, the quadrilateral structure formed by the hinge point of the bottom rod 410, the top plate component 430 and the two connecting components 420 are doubly limited. The position of the top plate component 430 is completely fixed and will not be displaced under the action of external force, ensuring the overall structural stability of the greenhouse in the closed state. When the opening angle of the greenhouse top needs to be adjusted, the drive motor 610 in the corresponding side drive mechanism 600 is activated according to the target flipping direction. The drive motor 610 drives the shaft 620 to rotate through helical gear transmission. The shaft 620 then drives the threaded shaft 510 in the corresponding adjustment mechanism 500 to rotate on the arch frame 200 through helical gear transmission. When the threaded shaft 510 rotates, it drives the positioning slider 521 connected to it to slide along the arch frame 200 through thread transmission, so that the extrusion assembly 520 moves as a whole towards the direction of the extrusion assemblies 520 that are staggered on the other side. During the movement, the inclined surface of the end of the positioning slider 521 continuously contacts the wedge block 532 and generates extrusion. The horizontal linear motion of the positioning slider 521 is converted into the vertical displacement of the positioning block 531 by the inclined plane, pushing the positioning block 531 to move out of the rectangular groove 411 along the length direction. During this process, the spring telescopic rod 540 shortens synchronously with the movement of the positioning block 531 and slides inside the first movable groove 522. The guide rod 551 slides synchronously with the positioning block 531 into the second movable groove 524, further compressing the spring 552 until the positioning block 531 is completely disengaged from the rectangular groove 411, completing the unlocking operation of the corresponding side connecting component 420. At this time, the other set of connecting components 420 is still in the locked state, providing a rotation fulcrum for subsequent angle adjustment. After unlocking the single-sided connecting component 420, the dual-axis motor 425 in the locking-side connecting component 420 is activated. The dual-axis motor 425 drives the first gear 424 to rotate synchronously through the output shafts on both sides. The first gear 424, through meshing with the second gear 433, drives the second gear 433 to rotate around the second positioning shaft 432, thereby causing the top rod 431 to rotate around the second positioning shaft 432, the hinge axis between the locking-side connecting component 420 and the top plate component 430. At the same time, the unlocking-side connecting component 420 rotates synchronously with the top plate component 430, around the first positioning shaft 422, the hinge axis between the bottom rod 410 and the top rod 410. The quadrilateral structure formed by the bottom rod 410, the top plate component 430, and the two sets of connecting components 420 undergoes adaptive angle changes, thereby achieving precise adjustment of the opening and closing angle of the greenhouse top. According to actual usage needs, the opening and closing range of the top plate assembly 430 can be precisely adjusted by controlling the rotation direction and number of rotations of the dual-axis motor 425; the flipping direction of the top plate assembly 430 can also be changed by switching the unlocked connection assembly 420 group, so as to realize the directional opening and closing of the middle area or the side area of ​​the greenhouse top: opening and closing of the middle area of ​​the greenhouse top can quickly dissipate the heat accumulated inside, and opening and closing of the side area can realize ventilation and heat dissipation inside the greenhouse. At the same time, by adjusting the tilt angle of the top plate assembly 430, the snow on the surface of the top plate assembly 430 can be quickly slid off, completing convenient snow removal operations. Once the greenhouse is adjusted to the target angle, the dual-axis motor 425 is stopped, keeping the top plate assembly 430 at the current adjustment angle. Then, the drive motor 610 is started in reverse, driving the threaded shaft 510 to rotate in the opposite direction via the shaft 620. This, in turn, drives the positioning slider 521 to slide and reset in the opposite direction via the threaded transmission. During the reset process of the positioning slider 521, the pressure on the wedge block 532 gradually disappears, the compressed spring 552 releases its elastic potential energy, and pushes the positioning block 531 to move in the opposite direction. The guide rod 551 slides and resets along the second movable groove 524, and the spring telescopic rod 540 extends and resets synchronously until the positioning block 531 re-engages into the rectangular groove 411, completing the re-locking of the connecting assembly 420 on this side and keeping the entire movable mechanism 400 in a stable state after the current adjustment.
