Technical Field

[0001] The utility model relates to the technical field of vegetable planting, in particular to a convenient opening and closing device for a vegetable planting heat preservation shed. Background Art

[0002] Greenhouse vegetable cultivation is a scientific method of cultivation. It uses a bamboo or steel frame covered with one or more layers of heat-insulating plastic film to form a greenhouse space. This structure can effectively prevent the loss of carbon dioxide produced during the growth of vegetables, thereby maintaining a good heat preservation effect in the greenhouse, allowing people to eat off-season vegetables.

[0003] The utility model patent with authorization announcement number CN213755951U discloses a planting shed for organic vegetable planting. The utility model includes a top protective film placed on the top of a support frame, a fixed column is fixedly installed at one end of the top protective film, a rotation limiting strip is connected to one end of the top protective film, an L-shaped clamping plate is placed at one end of the rotation limiting strip, a clamping block is welded at the top of the L-shaped clamping plate, one end of the L-shaped clamping plate is connected to the output shaft of the transmission motor, and a limiting hole is provided at one end of the L-shaped clamping plate and the clamping block. The protective film is driven to move by the rotation limiting strip to protect the greenhouse, and the cleaning rod is driven to rotate by the clamping block to clean the snow accumulated on the top protective film, thereby avoiding damage to the greenhouse caused by heavy snow accumulation. At the same time, the rotation limiting strip and the cleaning rod are fixed by the limiting clamping block, so as to facilitate limiting them when not in use, and at the same time, they can be quickly installed and fixed when needed.

[0004] Although the utility model can conveniently clean the top protective film, the utility model cannot open the top to fully receive sunlight in sunny weather to increase the light received by the plants.

[0026] See also Figure 1-Figure 4 , this embodiment provides a technical solution:

[0027] A convenient opening and closing device for a vegetable planting insulation greenhouse comprises a greenhouse 1, an opening and closing mechanism 2 is installed on the upper side of the greenhouse 1, a winding mechanism 3 is installed on the right side of the greenhouse 1, the opening and closing mechanism 2 comprises a support plate 21, an opening and closing motor 22 fixedly installed on the upper surface of the support plate 21, and a connecting rod 23 welded to the output shaft of the opening and closing motor 22, a support rod 24 is welded to the right end of the connecting rod 23, a heat preservation cloth 25 is installed on the left end of the support rod 24, and fastening ropes 26 are installed inside the front and rear sides of the heat preservation cloth 25. Through the above mechanism, the heat preservation cloth 25 can be opened through the opening and closing mechanism 2, so that the plants in the greenhouse 1 can receive light on sunny days.

[0028] Furthermore, the winding mechanism 3 includes two symmetrically placed support blocks 31, a winding rod 33 rotatably connected between the support blocks 31, and a winding motor 32 for controlling the rotation of the winding rod 33. A cleaning plate 34 is welded on the upper surface of the support block 31, and the cleaning plate 34 can clean impurities on the surface of the insulation cloth 25.

[0029] Furthermore, the top of the greenhouse 1 is in a semicircular structure in a front view, and a door is installed at the front side of the greenhouse 1. The semicircular structure facilitates the rotation of the support rod 24.

[0030] In this embodiment, the fastening rope 26 is made of an elastic rope, the length of which is smaller than the width of the insulation cloth 25 , and the elastic rope can fix the insulation cloth 25 on the top of the greenhouse 1 .

[0031] In this embodiment, there is a 30° angle between the cleaning plate 34 and the horizontal surface, and the right side surface of the cleaning plate 34 is in close contact with the upper surface of the insulation cloth 25, ensuring that impurities falling from the insulation cloth 25 will fall smoothly onto the cleaning plate 34.

[0032] In this embodiment, the right end of the cleaning plate 34 is made of rubber material, and the upper surface of the cleaning plate 34 is smooth to reduce friction generated during contact.

[0033] In this embodiment, the left end of the insulation cloth 25 is fixedly mounted on the reeling rod 33 , and a gap is left between the right end of the cleaning plate 34 and the top of the greenhouse 1 to facilitate the movement of the insulation cloth 25 .

[0034] In this embodiment, the upper surface of the support block 31 is located below the lower surface of the connecting rod 23 , and the output shaft of the winding motor 32 is coaxially connected to the winding rod 33 , so that the winding motor 32 can control the rotation of the winding rod 33 .

[0035] It is worth mentioning that the structures and working principles of the greenhouse 1, the opening and closing motor 22, and the winding motor 32 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0036] During the specific use of the convenient opening and closing device of the vegetable planting insulation greenhouse of this embodiment, when the opening and closing mechanism 2 is needed to open the insulation cloth 25 at the upper end of the greenhouse 1 to ensure that the vegetables inside the greenhouse 1 can receive direct sunlight, the opening and closing motor 22 is first started in reverse, and the winding motor 32 is started in forward direction. The opening and closing motor 22 controls the support rod 24 to rotate counterclockwise through the connecting rod 23. At the same time, the winding motor 32 controls the winding rod 33 to rotate clockwise. With the cooperation of the two, the insulation cloth 25 can be smoothly wound up by the winding rod 33. During the winding process, the cleaning plate 34 will clean the impurities on the upper surface of the insulation cloth 25.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
