[0025] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods and devices should be regarded as part of the specification.

[0026] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0027] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0028] As Figures 1 to 5 shown, an agricultural planting greenhouse provided by an embodiment of the present utility model includes a greenhouse top frame 1. There are multiple groups of the greenhouse top frame 1. Multiple connecting rods 2 are connected between the multiple groups of the greenhouse top frame 1. Both ends of the greenhouse top frame 1 are fixedly installed with support columns 3. A fixed column 4 is slidably connected to the surface of the support column 3. The support column 3 and the fixed column 4 are hollow to reduce their weight and facilitate installation. A lifting assembly 5 is arranged on one side of the fixed column 4. A tray 7 is fixedly installed on the lower surface of the fixed column 4. Two guide rails 8 are slidably connected to the lower surface of the tray 7. The lower surfaces of the two guide rails 8 are commonly fixedly installed with a base 9. The base 9 is fixedly installed on the ground. A telescopic assembly 6 is arranged between the two support columns 3. A support rod 10 is arranged on the upper surface of the telescopic assembly 6. One end of the support rod 10 is fixedly connected to the greenhouse top frame 1. Since most of the existing greenhouses are installed in a fixed structure, the internal space of the installed greenhouse cannot be adjusted. Due to the growth of crops, the volume of the crops is constantly changing. Different crops have different growth range requirements. When the living range in the greenhouse is not sufficient to meet the growth requirements of the crops, the yield of the crops will decrease, causing economic losses. Therefore, the support column 3 slides upward inside the fixed column 4 through the lifting assembly 5, changing the height of the support column 3, thereby realizing the adjustment of the height of the greenhouse. At the same time, the telescopic assembly 6 adjusts the distance between the two support columns 3, causing the tray 7 to slide above the guide rails 8 to change the distance between the two support columns 3, achieving the adjustment of the width of the greenhouse. The lifting assembly 5 and the telescopic assembly 6 cooperate with each other to complete the adjustment of the internal space of the greenhouse, facilitating the adjustment of appropriate growth requirements for different crops.

[0029] The greenhouse top frame 1 includes a frame top 101. The frame top 101 is fixedly installed on the upper surface of the support rod 10. Slide grooves 11 are opened on both sides of the frame top 101. The two slide grooves 11 are symmetrically arranged up and down. A frame plate 102 is slidably connected in the slide grooves 11. The two slide grooves 11 are arranged in a layered manner up and down, increasing the length of one end of the frame plate 102, facilitating the adjustment of the width of the greenhouse in cooperation with the telescopic assembly 6, thereby increasing the adjustment range of the width of the greenhouse. One end of the frame plate 102 is fixedly installed on the upper surface of the support column 3. When the position between the two support columns 3 changes, one end of the frame plate 102 moves with the support column 3, and the other end slides in the slide groove 11, thereby cooperating with the telescopic assembly 6 for the adjustment of the width inside the greenhouse.

[0030] The lifting component 5 includes a first rack 501, the first rack 501 is fixedly installed on one side of the support column 3, a long hole 12 corresponding to the first rack 501 is opened on one side of the fixed column 4, the first rack 501 is slidably connected in the long hole 12, the first rack 501 meshes with a first gear 502, a rotating shaft 503 penetrates through the center end of the first gear 502, and the first gear 502 is fixedly connected to the rotating shaft 503. Both ends of the rotating shaft 503 are rotatably connected to a fixed block 504. The fixed block 504 is arranged in a U shape. The fixed block 504 is fixedly installed on one side of the fixed column 4. A second gear 505 is rotatably connected to one side of the fixed block 504. The second gear 505 is fixedly connected to one end of the rotating shaft 503. A chain 506 is sleeved on the surface of the second gear 505. A third gear 507 is sleeved in the chain 506. One end of the third gear 507 is fixedly installed with a first motor 508. The first motor 508 is fixedly installed on one side of the fixed block 504.

[0031] By rotating the output shaft of the first motor 508, the third gear 507 drives the second gear 505 to rotate synchronously through the chain 506. Under the rotation of the second gear 505, the rotating shaft 503 drives the first gear 502 to rotate. Under the rotation of the first gear 502, the first rack 501 makes the support column 3 move upward along with the first rack 501, thereby realizing the adjustment of the height of the greenhouse, which is convenient for adjusting different heights according to the growth of different crops.

[0032] Limit strips 13 are arranged on both sides of the support column 3. Limit grooves 14 are opened on both sides inside the fixed column 4. The limit strips 13 and the limit grooves 14 are arranged in correspondence. The limit strips 13 are slidably connected in the limit grooves 14. When the support column 3 rises upward inside the fixed column 4, the limit strips 13 slide in the limit grooves 14, playing a role of limit and guidance, thereby increasing the connection between the support column 3 and the fixed column 4.

[0033] The telescopic component 6 includes a cross plate 601. Sliding grooves 15 are opened on both sides of the cross plate 601. The two groups of sliding grooves 15 are arranged in an inclined symmetry. An adjusting rod 602 is slidably connected in the sliding grooves 15. The adjusting rod 602 is fixedly installed on one side of the support column 3. A through hole 16 is communicated between the two groups of sliding grooves 15. A fourth gear 603 is rotatably connected in the through hole 16. The fourth gear 603 meshes with two second racks 604. The second racks 604 are fixedly installed on one side of the adjusting rod 602. One end of the fourth gear 603 is fixedly installed with a second motor 605. The second motor 605 is fixedly installed on the upper surface of the cross plate 601, and the output shaft of the second motor 605 penetrates through the upper surface of the cross plate 601. By driving the fourth gear 603 to rotate through the output shaft of the second motor 605, the two second racks 604 move in different directions respectively, changing the distance between the two support columns 3, thereby achieving the adjustment of the width of the greenhouse, which is convenient for adjusting the width of the greenhouse according to the growth requirements of different crops.
