Description

Technical Field

[0001] This utility model relates to the technical field of cabbage planting facilities, specifically a cabbage seedbed shade arch shed. Background Technology

[0002] Autumn cabbage sowing is generally best done in early June, with a harvest time of 80-90 days to supply the off-season market. During the seedling stage, high temperatures make seedling emergence difficult. Before sowing, the seedbed should be thoroughly watered, and after sowing, it should be covered with straw or leaves to keep the soil moist. After emergence, the cover should be removed promptly, and a small arched shed should be erected to provide shade and prevent direct sunlight.

[0003] Traditional shade arches are made of bamboo frames and plastic film. The bamboo frames need to be inserted first, and then the film needs to be covered. It is inconvenient to set up and take down the arches, and they are also easy to be damaged and difficult to rebuild. In addition, traditional shade arches can only provide long-term shade for cabbages. When the shade is no longer needed, they can only be completely removed, making them inconvenient to use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 2 A shading arch for cabbage seedling beds includes a frame and a film portion. The frame includes two sets of crossbar assemblies 10 and multiple arch poles 20, while the film portion includes multiple sheets of film 30. The lower end of each arch pole 20 is fitted onto one of the two sets of crossbar assemblies 10, and the arch pole 20 is slidably connected to the crossbar assemblies 10. A sheet of film 30 is placed between every two adjacent arch poles 20, and the outer edge of the film 30 is fixedly connected to the adjacent arch pole 20. Sliding the arch poles 20 allows the film 30 to be flattened or folded up, changing the usage state of the shading arch for cabbage seedling beds. A limiting mechanism is provided in the crossbar assembly 10 to fix the position of the arch poles 20, ensuring that the arch poles 20 are fixed after they have been moved to flatten the film 30, thus preventing movement of the arch poles 20 and film 30 during use.

[0022] See Figure 3The crossbar assembly 10 includes a support rod 11, a horizontal tube 12, a limiting mechanism, and a base 16. The support rod 11 and the horizontal tube 12 are parallel to each other and at the same height, and the adjacent ends of the horizontal tube 12 and the support rod 11 are welded and fixed to the base 16 as a whole. The limiting mechanism is located in the inner cavity of the horizontal tube 12 and includes springs 13 and insert shafts 15 in a number equal to the number of support rods 20, as well as a movable frame 14. The movable frame 14 can be movably disposed in the inner cavity of the horizontal tube 12, facing towards or away from the support rod 11. The two ends of the springs 13 are fixedly connected to the inner wall of the horizontal tube 12 and the movable frame 14, respectively, and the inner wall of the horizontal tube 12 connected to the springs 13 is set as a flat fixing surface 121 to increase the contact area when the two are connected and fixed. Multiple insert shafts 15 are fixedly connected at equal intervals on the side of the movable frame 14 facing the support rod 11. Under the action of the spring 13, the insert shafts 15 can pass through the horizontal tube 12 and be inserted into the support rod 20. After pushing the movable frame 14 to compress the spring 13, the insert shafts 15 can retract from the support rod 20 into the horizontal tube 12. The horizontal tube 12 has multiple openings with a diameter larger than the diameter of the insert shafts 15. Each insert shaft 15 passes through one opening to prevent interference with the movement of the insert shafts 15.

[0023] In this embodiment, the length of the movable frame 14 is adapted to the length of the horizontal tube 12, and both ends of the movable frame 14 have perpendicular locking blocks. This allows the movable frame 14 to be locked between the locking blocks at both ends and the ends of the horizontal tube 12. Thus, after the insertion shaft 15 passes through the horizontal tube 12 and is inserted into the support rod 20, the locking action between the locking blocks at both ends of the movable frame 14 and the horizontal tube 12 can maintain the position of the insertion shaft 15. When it is necessary to retract the insertion shaft 15 from the support rod 20 back into the horizontal tube 12, the movable frame 14 can be pushed forcefully to separate the locking blocks from the horizontal tube 12.

[0024] See Figure 4 The canopy pole 20 can be made of metal rod bent into an inverted "U" shape. Two connecting holes 21 are formed on the canopy pole 20, through which the support rods 11 of the two sets of crossbar assemblies 10 pass. These support rods 11 slide on the two connecting holes 21, and the canopy pole 20 is supported by the support rods 11 of the two sets of crossbar assemblies 10. Two insertion holes 22 are also formed on the canopy pole 20, each communicating with the adjacent connecting hole 21. The diameter of the insertion hole 22 is matched with the diameter of the insertion shaft 15, so that the insertion shaft 15 can be inserted into the insertion hole 22 to limit the position of the canopy pole 20.

[0025] See Figure 2 and Figure 5The cabbage seedling shade arch canopy may also include two sets of auxiliary supports 40. The two sets of auxiliary supports 40 are symmetrically arranged on opposite sides of the two sets of crossbar assemblies 10, and the side of the auxiliary support 40 facing the crossbar assembly 10 is fixedly connected to the base support 16 in the crossbar assembly 10. The bottom of the auxiliary support 40 is on the same plane as the bottom of the crossbar assembly 10, and the auxiliary support 40 can be fixed to the ground using locking devices such as steel nails or anchor rods. The auxiliary support 40 is used to ensure the frame is stably installed and fixed on the ground. The auxiliary support 40 includes a base 41 and multiple reinforcing ribs 42. The base 41 is L-shaped, and the multiple reinforcing ribs 42 are welded and fixed to the base 41 at intervals. Multiple fixing holes 43 are also formed on the base 41, penetrating downwards, allowing locking devices such as steel nails or anchor rods to pass through the fixing holes 43 to fix the base 41.

[0026] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
