Description

Technical Field

[0001] This utility model relates to a modular quick-release cigar tobacco shade net device. Background Technology

[0002] When planting cigar tobacco leaves, after the initial bushing stage, shade nets are typically installed in the cigar fields to block strong sunlight and lower temperatures. However, existing shade nets have the following problems:

[0003] 1. The shading net for cigar tobacco leaves needs to be installed after the posts and beams are installed, which makes disassembly and assembly inconvenient.

[0004] 2. Shade nets are completely enclosed, and in windy weather, they easily trap the wind, making them prone to being blown down and providing poor wind protection.

[0005] 3. After a year of exposure to wind and sun, the shade netting has accumulated a lot of dust, greatly reducing its light transmittance. It needs to be cleaned, but because the shade netting is a single piece of netting with a large area, it is difficult to clean.

[0006] 4. The existing shade nets are used to block sunlight on sunny days. On cloudy or rainy days, the nets normally need to be lifted manually. However, due to the large area of ​​the shade nets, it is impossible to lift them on cloudy days. Utility Model Content

Detailed Implementation

[0030] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0031] refer to Figures 1 to 7

[0032] A modular, quick-release cigar tobacco shade net device includes an umbrella handle 10. The upper part of the handle has an umbrella frame 20 that unfolds into a regular square pyramid shape. Each of the four sides of the umbrella frame is covered with a triangular light-transmitting mesh 30 that fits snugly against the frame and is fixed in place. The hypotenuses of adjacent light-transmitting meshes are connected to form a single unit. This umbrella-structured shade net device is easy to fold and multiple units can be unfolded and combined for use.

[0033] In this embodiment, to better secure the light-transmitting mesh and achieve folding, the umbrella frame includes a fixing ring 21 fixed to the upper end of the umbrella handle. Four supporting rods 22 are hinged at intervals along the circumferential direction on the fixing ring. A movable ring 23 is fitted onto the umbrella handle, and four diagonal support rods 24 are hinged at intervals along the circumferential direction on the movable ring. The upper ends of the diagonal support rods are hinged to the middle of the supporting rods. A triangular light-transmitting mesh is fixedly placed between adjacent supporting rods.

[0034] In another embodiment, to add fixing points to the light-transmitting mesh, a short support rod 25 is hinged to the fixing ring between two adjacent long support rods. When unfolded, the two adjacent long support rods and the short support rod between them are on the same plane. A short diagonal brace 26 is hinged to the movable ring between two adjacent diagonal braces, with the upper end of the short diagonal brace hinged to the middle of the short support rod. The length of the short support rod is slightly shorter than the length of the long support rod; for example, the length of the short support rod is equal to the height of the triangular light-transmitting mesh. The length of the short diagonal brace is slightly shorter than the length of the diagonal brace, thus better aligning them to form a plane.

[0035] In this embodiment, both the fixed ring and the movable ring are provided with slots 231 along the circumferential direction so that the long support rod, the short support rod, the diagonal brace, and the diagonal brace can be inserted into the corresponding slots. The long support rod and the short support rod are then hinged to the fixed ring via pins 232, and the diagonal brace and the diagonal brace are hinged to the movable ring via pins 232.

[0036] In this embodiment, the movable ring has a downwardly extending tube 27, and a spring pin is transversely inserted through the tube. The upper part of the umbrella handle is provided with a positioning hole 11 for insertion of the end of the spring pin after the umbrella frame is unfolded. Specifically, the spring pin consists of a pin 28 and a spring 29 sleeved on the pin. The two ends of the spring are fixed to the pin and the tube respectively, giving the pin a transversely contracting elastic force so that when the umbrella frame is unfolded, the pin can automatically insert into the positioning hole after the positioning hole moves into place. When the sunshade net device needs to be retracted, pulling the pin outward will disengage the pin from the positioning hole, allowing the movable ring to slide downward and retract the sunshade net device.

[0037] In this embodiment, the umbrella handle is made of square tubing to facilitate material sourcing. The lower end of the handle has a pointed tip, the end of which is blunted. This pointed tip allows for better insertion into the ground.

[0038] In this embodiment, to increase ventilation, at least one long slot 31 is provided at intervals from top to bottom along the height direction of the triangle on each side of the light-transmitting mesh. Specifically, three long slots can be provided, and the long slots are parallel to the bottom edge of the triangular light-transmitting mesh. The length of the three long slots gradually increases from top to bottom, thereby improving windproof performance.

[0039] In this embodiment, to improve the strength of the elongated slots and prevent them from cracking, each elongated slot is provided with an edging structure 32. The edging structure can be formed by sewing fabric or shade netting to the edges of the elongated slots.

[0040] In this embodiment, the light-transmitting net is a white shade net, which has a lower shading rate (about 30%-70%) compared to a black shade net, and a reflectivity of over 90%, which can effectively reduce temperature and reduce light loss.

[0041] In this embodiment, the light-transmitting mesh is sewn onto the umbrella frame, specifically, the light-transmitting mesh is fixed to the long support pole and the short support pole by sewing.

[0042] Instructions for use: After the cigar tobacco leaves have formed a dense thicket, insert the handle of the shade net device into the field and then open the canopy. Once opened, the individual shade net devices will seamlessly connect to form a continuous sheet. Open the canopy on sunny days and lower it on cloudy or rainy days to allow sunlight to reach the plants. After the tobacco harvest, the shade net devices can be easily removed without affecting the next rice planting season. After removal, the white shade netting on the canopy can also be easily cleaned.

[0043] If the terms "first" and "second" are used in the above description to define the components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of distinguishing the components in the description. Unless otherwise stated, the above terms have no special meaning.

[0044] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0045] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.
