Description

Technical Field

[0001] The present invention belongs to the technical field of protected agriculture, and specifically relates to a plastic greenhouse for machine-friendly cultivation of vegetables. Background Art

[0002] A plastic greenhouse for machine-friendly cultivation of vegetables is a facility suitable for mechanized cultivation of vegetables.

[0003] Currently, when installing a traditional plastic greenhouse for machine-friendly cultivation of vegetables, the main frame structure is inserted into the soil one by one to serve as the basic support framework of the greenhouse. After the installation is completed, a covering film is laid. As an important part of the greenhouse, the covering film is used to maintain the temperature and humidity inside the greenhouse and provide suitable environmental conditions for vegetable growth. However, in the traditional installation method, the laying of the covering film mostly relies on manual operation. Construction workers need to start from one end and carefully cover the surface of the main frame with the covering film.

[0004] But this manual installation method has obvious drawbacks. On the one hand, the speed of manual operation is relatively slow. Especially in the construction of large-area greenhouses, it will significantly reduce the installation efficiency and prolong the construction period. On the other hand, it is difficult to ensure the uniformity and consistency of the laying of the covering film by manual installation, and problems such as the covering film loosening and shifting are likely to occur, affecting the use effect of the greenhouse.

[0005] In addition, during the recycling process of the covering film, there are also many inconveniences. Since the fixing method between the covering film and the main frame is relatively cumbersome, during recycling, construction workers need to untie the fixing points one by one and then carefully remove the covering film from the main frame. This process is time-consuming and laborious. Therefore, both the recycling and installation efficiency of the covering film under the traditional installation method are relatively low. Summary of the Invention

[0006] To solve the problems raised in the above background art, the present invention provides a plastic greenhouse for machine-friendly cultivation of vegetables.

[0007] To achieve the above object, the present invention provides the following technical solution: A plastic greenhouse for machine-friendly cultivation of vegetables, including a main frame and a covering film, further including:

[0008] A sliding mechanism, which is arranged on both sides of the main frame and the covering film;

[0009] Among them, the sliding mechanism includes two mounting plates arranged on both sides of the main frame and the covering film. At the top of both mounting plates, tooth rings located at both ends of the main frame and the covering film are fixedly installed. Two sliding components are slidably connected to the surface of the tooth rings. On one side of the two sliding components, two motors I are fixedly installed. At the output ends of the two motors I, two gears I are fixedly installed. On the opposite sides of the two gears I, mounting discs are fixedly installed. On the opposite sides of the two mounting discs, storage rollers are arranged.

[0010] The adjusting mechanism is arranged at the other end of the sliding component and can increase the tension of the covering film.

[0011] Preferably, the adjusting mechanism includes a fixed ring fixedly connected to the other end of the sliding component. A sliding rod is slidably connected inside the fixed ring. A contact roller is rotatably connected to the surface of the sliding rod. At the top end of the surface of the sliding rod, a connecting ring is fixedly installed.

[0012] The driving mechanism is arranged at the top of the fixed ring and can drive the sliding rod to move.

[0013] Preferably, the driving mechanism includes a fixing plate fixedly connected to the top of the fixed ring. On one side of the fixing plate, a motor II is fixedly installed. The output end of the motor II penetrates through the fixing plate and is fixedly installed with a rotating disc. On one side of the rotating disc, a convex block located inside the connecting ring is fixedly installed.

[0014] Preferably, it further includes:

[0015] The limiting mechanism is arranged on the other side of the fixing plate. The limiting mechanism includes a gear II rotatably connected to the other side of the fixing plate. On one side of the gear II, a lead screw is fixedly installed. A threaded block is threadedly connected to the surface of the lead screw. At the bottom end of the threaded block, a contact plate is fixedly installed. The surface of the contact plate is slidably connected with a limiting ring, and one end of the limiting ring is fixedly connected to the fixed ring.

[0016] Preferably, it further includes:

[0017] The fixing component is arranged on the opposite sides of the two mounting discs. The fixing component is fixedly connected to a connecting shell on the opposite sides of the two mounting discs. Bolts are arranged inside the connecting shell and the storage roller.

[0018] Preferably, it further includes:

[0019] The supporting component is arranged inside the fixed ring. The supporting component is a supporting groove opened inside the fixed ring. A supporting block is slidably connected inside the supporting groove, and the number of the supporting blocks is two. On the opposite sides of the two supporting blocks, the surfaces are fixedly connected to the surface of the connecting ring.

[0020] Preferably, a floor plug is fixedly installed at the bottom end of the mounting plate. The number of the floor plugs is multiple, and they are arranged in an array at the bottom end of the mounting plate.

[0021] Preferably, there is a gap between the rotating disc and the connecting ring. The convex block is circularly designed, and the surface of the convex block fits against the inner wall of the connecting ring.

[0022] Preferably, both the abutting plate and the limiting ring are square-shaped, and the surface of the abutting plate is smooth.

[0023] Preferably, the fixing ring is U-shaped and is mirror-designed.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] In the present invention, one end of the covering film is connected to the surface of the storage roller, or the storage roller equipped with the covering film is installed inside the connecting shell. Then, the first motor can be driven to rotate the first gear, the mounting disc, and the storage roller. Furthermore, the rotating first gear will move along the surface of the toothed ring, and the first gear will drive the mounting disc and the storage roller to move. During the movement of the storage roller, the entire covering film can be wound and installed. Finally, by driving the first motor, the storage roller rotates and moves along the surface of the toothed ring, thereby efficiently completing the winding and installation work of the covering film, significantly improving the efficiency of covering film recycling and installation, and bringing great convenience to vegetable planting.

[0026] In the present invention, the second motor is driven to rotate the rotating disc and the convex block. The convex block will slide inside the connecting ring and push the connecting ring, the sliding rod, and the abutting roller to move. The surface of the abutting roller will contact the surface of the covering film and will abut against the main frame, increasing the tension of the covering film. Finally, by driving the driving mechanism, the abutting roller fits against the surface of the covering film, and at the same time, the abutting roller abuts against the main frame, enabling the storage roller to always maintain a stable state during the winding and unwinding process, thereby evenly and smoothly recycling and installing the covering film, and greatly improving the operation effect.

[0027] In the present invention, when the rotating disc rotates, the rotating disc will drive the second gear and the lead screw to rotate. The threaded block will move on the lead screw, and the threaded block will drive the abutting plate to slide inside the limiting ring. The surface of the abutting plate will contact one side of the abutting roller, which can limit the covering film. Finally, by the rotating disc linking the second gear, the abutting plate contacts the surface of the abutting roller, limiting the position of the covering film, preventing it from shifting, ensuring the flatness and accuracy of the covering film laying, and thus effectively improving the operation quality.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] As Figures 1 to 9 shown, the present invention provides a plastic greenhouse for vegetable machine-friendly cultivation, including a main frame 1 and a covering film 2, and further including:

[0040] A sliding mechanism 3, which is arranged on both sides of the main frame 1 and the covering film 2;

[0041] Among them, the sliding mechanism 3 includes two mounting plates 301 arranged on both sides of the main frame 1 and the covering film 2. At the top of the two mounting plates 301, tooth rings 302 located at both ends of the main frame 1 and the covering film 2 are fixedly installed. Two sliding components 303 are slidably connected to the surface of the tooth ring 302. On one side of the two sliding components 303, two first motors 304 are fixedly installed. At the output ends of the two first motors 304, two first gears 305 are fixedly installed. On the opposite sides of the two first gears 305, mounting discs 306 are fixedly installed. On the opposite sides of the two mounting discs 306, storage rollers 307 are arranged;

[0042] The adjusting mechanism 4 is arranged at the other end of the sliding component 303 and can increase the tension of the covering film 2.

[0043] Adopting the above solution: Through the design of the sliding mechanism 3, one end of the covering film 2 can be connected to the surface of the storage roller 307, and then the first motor 304 can be driven to rotate the first gear 305, the mounting disc 306 and the storage roller 307. The storage roller 307 will wind the covering film 2 on its surface. And the first gear 305 meshes with the tooth ring 302. Then the rotating first gear 305 will move along the surface of the tooth ring 302. The sliding component 303 will roll along the surface of the tooth ring 302, making the movement of the first gear 305 smoother. Then the first gear 305 will drive the mounting disc 306 and the storage roller 307 to move. During the movement of the storage roller 307, the entire covering film 2 can be wound up;

[0044] When installing the covering film 2, the storage roller 307 loaded with the covering film 2 can be installed between the mounting discs 306, and then one end of the covering film 2 is fixed. At this time, the first motor 304 is driven to rotate the first gear 305, the mounting disc 306 and the storage roller 307 in the reverse direction. And the covering film 2 will separate from the surface of the storage roller 307. Then the mounting disc 306 and the storage roller 307 will move along the surface of the tooth ring 302. Thus, the entire covering film 2 can be covered on the surface of the main frame 1, improving the installation efficiency. Finally, by driving the first motor 304 to rotate the storage roller 307 and move along the surface of the tooth ring 302, the winding and installation work of the covering film 2 can be efficiently completed, significantly improving the recycling and installation efficiency of the covering film 2 and bringing great convenience to vegetable planting.

[0045] As Figure 3 and Figure 7 shown, the adjusting mechanism 4 includes a fixing ring 401 fixedly connected to the other end of the sliding component 303. A sliding rod 402 is slidably connected inside the fixing ring 401. A contact roller 403 is rotatably connected to the surface of the sliding rod 402. At the top of the surface of the sliding rod 402, a connecting ring 404 is fixedly installed;

[0046] The driving mechanism 5 is arranged at the top of the fixing ring 401 and can drive the sliding rod 402 to move.

[0047] Adopting the above solution: Through the design of the adjusting mechanism 4, while the winding roller 307 winds or installs the covering film 2, the driving mechanism 5 can be driven to drive the connecting ring 404, the sliding rod 402 and the abutting roller 403 to move. The sliding rod 402 will slide inside the fixed ring 401, and then the surface of the abutting roller 403 will contact the surface of the covering film 2 and will abut against the main frame 1. When the winding roller 307 moves along the toothed ring 302, due to the frictional force between the main frame 1 and the abutting roller 403, the first motor 304 will roll, and then the first motor 304 can increase the tension of the covering film 2, so that the winding roller 307 can evenly recycle and install the covering film 2. Finally, by driving the driving mechanism 5, the abutting roller 403 is attached to the surface of the covering film 2, and at the same time, the abutting roller 403 abuts against the main frame 1, so that the winding roller 307 can always maintain a stable state during the winding and unwinding process, and then evenly and smoothly recycle and install the covering film 2, greatly improving the operation effect.

[0048] As Figure 8 and Figure 9 As shown, the driving mechanism 5 includes a fixing plate 501 fixedly connected to the top end of the fixed ring 401. A second motor 502 is fixedly installed on one side of the fixing plate 501. The output end of the second motor 502 penetrates through the fixing plate 501 and is fixedly installed with a rotating disk 503. A convex block 504 located inside the connecting ring 404 is fixedly installed on one side of the rotating disk 503.

[0049] Adopting the above solution: Through the design of the driving mechanism 5, the second motor 502 can be used to rotate the rotating disk 503. The rotating disk 503 will drive the convex block 504 to slide inside the connecting ring 404. During the sliding process, the connecting ring 404 and the sliding rod 402 will be pushed to move, so that the sliding rod 402 contacts the surface of the covering film 2.

[0050] As Figure 8 and Figure 9 As shown, it further includes:

[0051] A limiting mechanism 6, which is arranged on the other side of the fixing plate 501. The limiting mechanism 6 includes a second gear 601 rotatably connected to the other side of the fixing plate 501. A lead screw 602 is fixedly installed on one side of the second gear 601. A threaded block 603 is threadedly connected to the surface of the lead screw 602. An abutting plate 605 is fixedly installed at the bottom end of the threaded block 603. A limiting ring 604 is slidably connected to the surface of the abutting plate 605, and one end of the limiting ring 604 is fixedly connected to the fixed ring 401.

[0052] Adopting the above solution: Through the design of the limiting mechanism 6, when the rotating disk 503 rotates, since the rotating disk 503 meshes with the second gear 601, the rotating disk 503 will drive the second gear 601 to rotate, and the second gear 601 will drive the lead screw 602 to rotate. Since the lead screw 602 is threadedly connected to the threaded block 603, the threaded block 603 will move on the lead screw 602, and the threaded block 603 will drive the contact plate 605 to slide inside the limiting ring 604. The surface of the contact plate 605 will contact one side of the contact roller 403. Since the size of the contact roller 403 is the same as that of the covering film 2, the contact plate 605 can limit the covering film 2. Finally, through the linkage of the rotating disk 503 and the second gear 601, the contact plate 605 contacts the surface of the contact roller 403, limiting the position of the covering film 2, preventing it from shifting, ensuring the flatness and accuracy of the laying of the covering film 2, and effectively improving the operation quality.

[0053] As Figure 6 shown, it further includes:

[0054] A fixing component 7, which is arranged on the opposite side of the two mounting disks 306. The fixing component 7 is fixedly connected to a connecting shell 701 on the opposite side of the two mounting disks 306, and bolts 702 are arranged inside the connecting shell 701 and the storage roller 307.

[0055] Adopting the above solution: Through the design of the fixing component 7, the storage roller 307 can be inserted into the inside of the connecting shell 701, and then the bolts 702 can be installed inside the connecting shell 701 and the storage roller 307, thereby completing the installation of the storage roller 307, and then the covering film 2 can be installed and recycled.

[0056] As Figure 8 shown, it further includes:

[0057] A supporting component 8, which is arranged inside the fixing ring 401. The supporting component 8 is provided with a supporting groove 801 opened inside the fixing ring 401. A supporting block 802 is slidably connected inside the supporting groove 801, and the number of the supporting blocks 802 is two. The opposite sides of the two supporting blocks 802 are fixedly connected to the surface of the connecting ring 404.

[0058] Adopting the above solution: Through the design of the supporting component 8, when the connecting ring 404 moves, it will drive the supporting block 802 to slide inside the supporting groove 801, and the surface of the supporting block 802 fits with the inner wall of the supporting groove 801, thereby being able to limit and support the connecting ring 404 and the sliding rod 402, and ensuring the stability of the movement of the sliding rod 402.

[0059] As Figure 3 and Figure 8As shown, a floor socket 9 is fixedly installed at the bottom end of the mounting plate 301. The number of floor sockets 9 is multiple, and they are arranged in an array at the bottom end of the mounting plate 301. There is a gap between the rotating disk 503 and the connecting ring 404. The convex block 504 is circularly designed, and the surface of the convex block 504 fits against the inner wall of the connecting ring 404.

[0060] Adopting the above scheme: Through the design of the floor socket 9, the floor socket 9 can be inserted into both sides of the main frame 1 and the covering film 2, so as to fix the mounting plate 301. Then, the toothed ring 302 can be installed at the top end of the mounting plate 301 through a fixing member. Then, the covering film 2 can be installed and wound. After the covering film 2 is wound or installed, the entire device can be disassembled to prevent the device from being exposed to the outside for a long time, thereby improving the service life of the device; Through the design of the connecting ring 404 of the rotating disk 503, since there is a gap between the rotating disk 503 and the connecting ring 404, the connecting ring 404 will not block the rotation of the rotating disk 503. And the surface of the convex block 504 fits against the inner wall of the connecting ring 404, so that the connecting ring 404 can move smoothly.

[0061] As Figure 8 and Figure 9 shown, both the abutting plate 605 and the limiting ring 604 are square in design, and the surface of the abutting plate 605 is smooth. The fixing ring 401 is U-shaped in design and is mirror-designed.

[0062] Adopting the above scheme: Through the design of the limiting ring 604 and the abutting plate 605, since both the abutting plate 605 and the limiting ring 604 are square in design, the limiting ring 604 can limit the abutting plate 605. And the abutting plate 605 is smooth, so it can move more smoothly inside the limiting ring 604. Through the design of the fixing ring 401, since the fixing ring 401 is U-shaped in design, when the fixing ring 401 moves, it will not interfere with the covering film 2. And the fixing ring 401 is mirror-designed, so as to ensure the stable movement of the sliding rod 402 and the abutting roller 403.

[0063] The working principle and usage process of the present invention:

[0064] First, the operator inserts the floor socket 9 into the soil on both sides of the main frame 1 and the covering film 2, and installs the toothed ring 302 at the top end of the mounting plate 301. One end of the covering film 2 can be connected to the surface of the storage roller 307, or the storage roller 307 equipped with the covering film 2 can be installed inside the connecting shell 701. Then, the motor 304 can be driven to rotate the gear 305, the mounting disk 306 and the storage roller 307. Then, the rotating gear 305 will move along the surface of the toothed ring 302, and the gear 305 will drive the mounting disk 306 and the storage roller 307 to move. During the movement of the storage roller 307, the entire covering film 2 can be wound and installed.

[0065] While the take-up roller 307 winds or installs the covering film 2, the motor two 502 can be driven to rotate the rotating disk 503 and the bump 504. The bump 504 will slide inside the connecting ring 404 and push the connecting ring 404, the sliding rod 402 and the abutting roller 403 to move. The surface of the abutting roller 403 will be in contact with the surface of the covering film 2 and will abut against the main frame 1, increasing the tension of the covering film 2, so that the take-up roller 307 can evenly recycle and install the covering film 2;

[0066] When the rotating disk 503 rotates, the rotating disk 503 will drive the gear two 601 and the lead screw 602 to rotate. The threaded block 603 will move on the lead screw 602, and the threaded block 603 will drive the abutting plate 605 to slide inside the limiting ring 604. The surface of the abutting plate 605 will contact one side of the abutting roller 403, which can limit the covering film 2, and finally complete the operation process.

[0067] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0068] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
