Description

Technical Field

[0001] The utility model belongs to the field of citrus cold protection, in particular to an outdoor cold protection device for citrus. Background Art

[0002] Since citrus fruits are native to the warm and humid subtropical areas, they prefer warm climate conditions but fear severe cold in winter, especially lemons, kumquats, grapefruits, sweet oranges, etc. Even Wenzhou mandarin oranges and ordinary citrus varieties will suffer from periodic frost damage if cultivated in the Yangtze River Basin in my country.

[0003] In the prior art, most growers use cold-proof cloth to evenly wrap the surface of citrus trunks to achieve the purpose of cold resistance and high yield. However, due to the rough bark on the surface of citrus trunks and the large number of protrusions on the trunks, the cold-proof cloth and the trunks have a poor fit, which greatly affects the cold-proof effect of the cold-proof cloth, and the entire wrapping process is troublesome, time-consuming and laborious. In addition, although there are also growers who directly put cold-proof bags on citrus to keep out the cold, the cold-proof bags will press down on the citrus and affect its growth. Utility Model Content

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0016] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0017] Combination Figure 1-3 As shown, the outdoor cold-proof device includes a hanger 1, on which at least one set of suspension components 2 is provided, and a cold-proof bag 16 for cold protection is suspended at the bottom of the suspension component 2, and the suspension component includes an adjusting frame 5 and a connecting block 3, on which a pair of notches 4 are opened, and the adjusting frame 5 penetrates into the notches 4, and external tooth surfaces 6 are formed on both sides of the adjusting frame 5, and a locking short block 7 is also slidably provided in the notch 4, and an internal tooth surface (blocked in the figure) is formed on the inner side of the locking short block 7, and the external tooth surface 6 on the same side is meshed and installed with the internal tooth surface, and a pair of compression springs 8 are provided at the outer side of the locking short block 7 and at the corresponding positions of the connecting block, a locking nut 9 is screwed into the connecting block 3, and the locking nut 9 conflicts with the locking short block 7, and a guide rod 10 is provided on the connecting block 3, and the top of the guide rod 10 penetrates through the adjusting frame 5 and is fixed on the hanger 1, and the bottom of the adjusting frame 5 is provided with a hook 11 for hanging the cold-proof bag.

[0018] Since citrus is native to the subtropical warm and humid forest areas, it likes warm climate conditions but fears severe cold in winter. In the cold winter, this device can be used to take cold-proof measures for citrus, so as to achieve the purpose of cold-resistance and high yield.

[0019] In actual planting conditions, citrus fruits are planted in rows with appropriate spacing. When using this device to protect citrus fruits from the cold, firstly, a corresponding number of suspension components are set on the hanger according to the number of citrus fruits. The suspension components are located directly above the citrus fruits. Then, a cold-proof bag is put on each citrus fruit. A short rope is provided on the top of the cold-proof bag, and the short rope is tied to the hook. This device protects citrus fruits from the cold by putting cold-proof bags on citrus trees, thereby achieving the purpose of cold resistance and high yield. The whole process is relatively simple, time-saving and labor-saving. In addition, the cold-proof bags can be recycled and reused later.

[0020] In this device, the hanging height of the cold-proof bags can be adjusted according to the height of the citrus, so that each cold-proof bag can be in a hanging state during the cold-proof process, which can effectively avoid the cold-proof bags pressing down on the citrus and preventing the growth of the citrus.

[0021] When you want to adjust the hanging height of the cold-proof bag according to the height of the citrus, you only need to adjust the height of the hook. Specifically: first hold the adjustment frame, loosen the two locking nuts, and then move the connecting block along the height direction of the adjusting frame to adjust the height of the adjusting frame, and the hook is adjusted synchronously to adapt to citrus of different heights. In the process of moving the connecting block, due to the action of the compression spring, the outer tooth surface of the adjusting frame still remains in meshing with the inner tooth surface of the locking short block on the same side. After the hanging height of the adjusting frame is determined, tighten the locking nut until the locking nut contacts the locking short block, and the locking short block is locked on the adjusting frame, and the adjustment is now complete. Finally, tie the short rope on the cold-proof bag to the hook.

[0022] During the process of adjusting the height of the hook, the connecting block moves along the height direction of the adjusting frame. During the movement of the connecting block, the guide rod plays a guiding role, and the entire adjustment process is more stable under the action of the guide rod.

[0023] In this structure, if Figure 1 In the embodiment, the hanger 1 is provided with a fixed sleeve 12, and the fixed sleeve 12 is provided with a hanging rope 13 downward, and the hanging rope is connected to the guide rod. In actual situations, the fixed sleeve can slide on the hanger to adapt to the position of the citrus, and after the fixed sleeve is determined, the fixed sleeve can be fixed on the hanger by bolt locking or the like. The hanging rope is generally a steel wire, and the hanging height of the suspension assembly can be increased by setting the hanging rope. At the same time, setting the hanging rope can also facilitate the hanging of the cold-proof bag.

[0024] As a preferred structure, Figure 2 In the embodiment, the adjusting frame 5 is an n-shaped structure, a stopper 14 is provided at the bottom of the adjusting frame through a fixing nut, and the hook 11 is mounted on the stopper 14. A threaded hole 15 is provided on the stopper. The threaded hole 15 is used to mount the hook 11.

[0025] In this structure, the connection block can be removed from the adjustment frame. When the connection block needs to be removed from the adjustment frame, first unscrew the fixing nut to remove the block from the bottom of the adjustment frame, then loosen the two locking nuts, and finally move the connection block downward until the connection block is separated from the adjustment frame. In addition, the entire suspension assembly can also play the role of counterweight during the cold protection process.

[0026] 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 and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
