Description

Technical Field

[0001] This utility model relates to the field of landscape greening maintenance technology, specifically a new type of shading device for landscape greening seedlings. Background Technology

[0002] With the development of landscape architecture, the construction of forest parks, scenic spots, nature reserves, urban parks, and various recreational green spaces has become increasingly widespread, and the urban green coverage rate has continued to improve, adding more greenery and vitality to the living environment. In landscape greening maintenance, newly planted saplings need shading protection under the high temperature and strong sunlight conditions in summer to reduce water transpiration and improve the survival rate.

[0003] Currently, common shading measures often employ fixed shade sheds or simple supports combined with shade netting. However, these structures are often difficult to flexibly adapt to the actual needs of different tree canopy sizes, planting row spacing, and plot shapes. Especially in nurseries and large-scale newly planted areas, where tree spacing varies and growth stages differ, shade netting of varying widths, lengths, and heights is required.

[0020] Furthermore, the lifting assembly includes two guide grooves corresponding to the side walls of two support tubes 3, two guide columns 33 welded to the side walls of two support columns 7, the two guide columns 33 slidingly connected within the two guide grooves, two gear mounting blocks 9 welded to the side walls of two support tubes 3, a connecting column 6 mounted between the two gear mounting blocks 9 via a bearing, a first handwheel 4 welded to the outside of one end of the connecting column 6, a ratchet 10 welded to the surface of the connecting column 6, a pawl 12 fixedly mounted on the outer surface of the gear mounting block 9, the pawl 12 meshing with the ratchet 10, two gear through grooves corresponding to the inside of the two gear mounting blocks 9, and two gears 11 welded to the surface of the connecting column 6 within the gear through grooves, two racks 8 welded to the side walls of two support columns 7, two gear slots corresponding to the side walls of two support tubes 3, and the two gears 11 partially meshing with the corresponding racks 8 through the corresponding gear slots, allowing the device to adjust its height.

[0021] Furthermore, the width adjustment assembly includes two worm gear mounting blocks 18 welded to the middle of the upper surface of the mounting plate 13. A worm gear 17 is mounted between the two worm gear mounting blocks 18 via bearings. One end of the worm gear 17 passes through one side of the worm gear mounting block 18 and is welded to a second handwheel 16. Two first bevel gears 20 are correspondingly mounted on the side walls of the two support columns 7 near their upper ends via bearings. Two fixing rods 21 are correspondingly welded to the lower surfaces of the two first bevel gears 20. Two fixing columns 22 are correspondingly mounted on the lower surfaces of the other ends of the two fixing rods 21 via bearings. The upper ends of the two support columns 7... Two worm gear mounting blocks are installed accordingly, and a worm gear mounting rod 14 is installed between the two worm gear mounting blocks via a bearing. Two second bevel gears 19 are welded to the side walls of the worm gear mounting rod 14 near both ends. A worm gear 15 is connected to the middle side wall of the worm gear mounting rod 14 via a key. The worm gear 15 meshes with the worm 17. Two limiting blocks 23 are symmetrically welded to the center of the side wall of each support column 7. Two limiting posts 24 are welded to the lower surface of the two fixing rods 21, so that the device can match the support width and provide shading for seedlings of different widths with different shade nets 1.

[0022] Furthermore, the shading assembly includes two fixed posts 22 of each of the two support frame assemblies, with two iron wires 32 fixedly connected between them. Several movable fixing rings 29 are fitted on the two iron wires 32, and a shading net 1 is fixedly installed between the several movable fixing rings 29.

[0023] Furthermore, two fixed rings 28 are fixedly connected to the two fixed columns 22 of a support frame assembly, and the two fixed rings 28 are fixedly connected to one side of the shade net 1, while the upper end of the movable drive block 30 is fixedly connected to the other side of the shade net 1.

[0024] Furthermore, the sidewalls where the two drive wheels 27 contact the rope 31 are made of rubber.

[0025] Working principle: Location relocation and initial setup: Workers use bolts to fix the device to the cement ground on both sides of the sapling planting row that needs shade in the garden, completing the initial positioning of the device.

[0026] Height Adjustment: Turn the first handwheel 4 clockwise or counterclockwise to rotate the connecting column 6, causing the gear 11 fixed to it to rotate. The gear meshes with the rack 8 welded to the side of the support column 7, thereby driving the support column 7 to rise or fall smoothly within the support tube 3, bringing the entire ceiling structure to the appropriate height. After adjustment, the pawl 12 automatically engages with the tooth groove of the ratchet 10 under the action of the spring, locking the height and preventing accidental fall.

[0027] Width Adjustment: Key Pre-set Steps for Width Adjustment: Before installing the shade net and wire, the second handwheel 16 must be cranked according to the row spacing of the saplings and the existing width of the shade net. The worm gear 17 drives the worm wheel 15 and bevel gear pairs 19 and 20, causing the fixing rod 21 to move synchronously towards or away from the fixing posts 22 on both sides, precisely adjusting to the required span. The self-locking characteristic of the worm gear ensures that the adjusted width remains stable, providing accurate support endpoints for installing wire and shade net of specific lengths.

[0028] Shading System Installation: After the width is preset, install the shading components that match the current width. Fix the ends of two appropriately sized wires 32 to the pre-adjusted fixing posts 22 on both sides, and pull them taut to form parallel tracks. Fix one edge of the shading net 1 to the fixing post at the starting end using fixed rings 28. Pass the shading net body through multiple movable fixing rings 29 and loop these rings onto the two wires. Connect and fix the two ends of the rope 31 to form a complete closed loop. Loop this closed loop rope onto the two drive wheels 27 and maintain moderate tension. Then, securely fix a point on the rope to the moving drive block 30. Connect the other edge of the shading net to the moving drive block 30.

[0029] Opening and closing the shade: Turning the third handwheel 25 clockwise drives a drive wheel 27 to rotate. The drive wheel causes the closed-loop rope 31 to circulate, and the movable drive block 30 fixed to the rope moves to one side accordingly. The movable drive block pulls the edge of the shade net 1, causing the shade net to smoothly unfold along the two parallel wire tracks 32 through the movable fixed ring 29 on it, until it completely covers the area of ​​the seedlings below. When the seedlings need sunlight, turning the third handwheel 25 counterclockwise moves the drive block in the opposite direction, pulling the shade net back to the fixed ring 28 of the fixed post 22 on the other side, so that the area of ​​the seedlings is completely exposed.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
