[0002] In landscaping maintenance, various mulching materials are widely used to cover tree pits to conserve water resources. Traditional mulching materials include bark, sawdust, expanded clay pellets, and plastic sheeting, but these materials are labor-intensive to install. Bark, sawdust, or expanded clay pellets require extensive manual labor for laying, while plastic sheeting needs to be secured to prevent it from being blown away by the wind. Furthermore, removing these materials after installation is troublesome if needed. Therefore, it is urgent to address the need for more convenient and rapid installation and removal of mulching materials based on actual on-site maintenance requirements. Utility Model Content

Detailed Implementation
[0022] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] like Figure 1 As shown, a retractable tree pit water-retaining collar for trees and shrubs includes a semi-circular water-retaining membrane 1, a retractable ring, a rotating shaft 2, a hook 5, and fixed anchor points 4; the semi-circular water-retaining membrane 1 includes two, and multiple fixed anchor points 4 are respectively set on the arc edges of the two semi-circular water-retaining membranes 1, and the semi-circular water-retaining membrane 1 is connected to the retractable ring through the fixed anchor points 4;
[0025] The retractable ring includes two telescopic arms 3, which are respectively arranged around the arc edges of two semi-circular water-retaining membranes 1. The telescopic arms 3 are semi-circular arc-shaped. One end of the two telescopic arms 3 is rotatably connected by a rotating shaft 2, and the other end of the two telescopic arms 3 is detachably connected by a hook 5.
[0026] The telescopic arm 3 includes a first telescopic section 301, a second telescopic section 302, a third telescopic section 303, and a fourth telescopic section 304 connected sequentially from front to back; the first telescopic section 301, the second telescopic section 302, and the third telescopic section 303 are respectively provided with telescopic channels 305; the second telescopic section 302, the third telescopic section 303, and the fourth telescopic section 304 are respectively fitted into the telescopic channels 305.
[0027] The expandable ring consists of two semi-circular telescopic arms, each comprising four segments: a first telescopic section, a second telescopic section, a third telescopic section, and a fourth telescopic section. Preferably, each segment is 25-30 cm long and forms a nested structure via telescopic channels, allowing for free extension or shortening. One end of each telescopic arm is connected by a pivot, allowing rotation around the pivot. The other end of each telescopic arm has a hook for locking the two arms together. Each telescopic arm of the expandable ring is fixed with a semi-circular water-retaining membrane, secured by anchor points on the expandable ring. The semi-circular water-retaining membrane is made of a high-polymer water-retaining material, such as polypropylene, polyethylene, or other polymers. The water-retaining collar secures the tree trunk between the two semi-circular water-retaining membranes, with the expandable ring placed around the outer edge of the tree pit, allowing the water-retaining membranes to cover the pit and retain moisture.
[0028] A retractable tree pit water-retaining collar for trees and shrubs, when used, such as Figure 2As shown, the expandable ring and two semi-circular water-retaining membranes fixed on it together constitute a water-retaining neckerchief. The neckerchief holds the tree trunk between the two membranes, and the expandable ring is placed on the outer edge of the tree pit, with the membranes covering the pit to retain water. The expandable ring can extend or shorten, rotating freely with a pivot, allowing the neckerchief to be adjusted to fit different tree pit sizes for trees and shrubs. The neckerchief can be placed directly on the tree pit. Because the expandable ring has some weight and the trunk is secured between the membranes, no further securing measures are needed, and it will not be blown away by the wind.
[0029] Meanwhile, water-retaining neckers can be quickly installed or removed according to actual on-site maintenance needs. For example, they can be quickly installed during the dry season to retain water in the tree pit; and during the rainy season, they can be quickly installed to reduce rainwater accumulation in the tree pit and mitigate waterlogging damage. During routine maintenance, the water-retaining neckers can be quickly removed to allow for other operations such as loosening the soil or weeding in the tree pit; and before rainfall during the dry season, the water-retaining neckers can be quickly removed to increase the tree pit's ability to retain rainwater.
[0030] In addition, during the dry season, if it rains, the water-retaining rings can be quickly removed in advance to increase the amount of rainwater collected in the tree pit; after the rain, the water-retaining rings can be quickly re-laid to retain water. During the rainy season, if there is heavy rainfall, the water-retaining rings can be laid in the tree pit as needed to reduce the accumulation of rainwater in the tree pit and mitigate waterlogging damage.
[0031] like Figure 1 As shown, the outer diameters of the first telescopic joint 301, the second telescopic joint 302, the third telescopic joint 303, and the fourth telescopic joint 304 gradually decrease from the pivot 2 to the latch 5. The second telescopic joint 302, the third telescopic joint 303, and the fourth telescopic joint 304 are each retracted into the telescopic channel 305, reducing the space occupied after retraction and facilitating transportation.
[0032] like Figure 1 As shown, the rotating shaft 2 passes through the rear of the two first expansion joints 301, and the two first expansion joints 301 are rotatably connected by the rotating shaft. The connection via the rotating shaft facilitates production and results in a compact structure. Furthermore, the rotating shaft is located at the thickest section of the outer diameter of the first expansion joint 301, while the hook 5 is located at the thinnest section, making installation more convenient and ensuring greater stability after installation.
[0033] like Figure 3 As shown, the hooks 5 are respectively disposed at the front end of the fourth telescopic section 304, and the hooks 5 are arc hooks that can hook together. The connection by the hooks 5 facilitates production and results in a compact structure.
[0034] like Figure 1 As shown, a fixed anchor point 4 is provided at each end of the first expansion joint 301. Figure 1As shown, a fixed anchor point 4 is provided at the front end of the second expansion joint 302, the third expansion joint 303, and the fourth expansion joint 304. The semi-circular water-retaining membrane 1 is connected to the expandable ring through the fixed anchor point 4; when the expandable ring is extended or retracted, the semi-circular water-retaining membrane 1 can be folded, reducing the space occupied after shrinking and facilitating transportation.
[0035] This utility model aims to propose a retractable water-retaining collar for tree and shrub pits, which is an improvement over traditional covering water-retaining measures. It can adapt to the actual needs of on-site maintenance by quickly laying or taking back the covering material. The retractable ring can extend and retract and rotate freely with the pivot, adapting to the water retention of tree and shrub pits of different sizes. It can greatly save labor costs and improve efficiency; and when retracted, it reduces the space occupied and facilitates transportation.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
