Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation devices, in particular to an antifreeze cover for fruit trees. Background Art

[0002] The process of cultivating apple seedlings goes through four seasons: spring, summer, autumn and winter. The temperature is low in winter. Fruit trees, especially young ones, are prone to frost damage due to their low degree of lignification, tender and weak plants, and poor resistance to adversity. Therefore, frost protection of fruit seedlings in winter has become a top priority for fruit farmers.

[0003] There are many ways to protect fruit seedlings from freezing in the prior art. The more traditional technology is to wrap the trunk of the fruit tree with wheat straw, straw rope or cloth bag. This method is labor-intensive, time-consuming and labor-intensive, and the material for wrapping the trunk of the fruit tree can only be used once and cannot be reused. The rotten material will also pollute the environment. There are also many more advanced methods, such as a winter antifreeze cover for fruit trees disclosed in Chinese Patent Authorization Announcement No. CN206413503U, which includes a thermal insulation layer and a waterproof layer. The outer side of the thermal insulation layer is connected to the waterproof layer, and an inner core is provided inside the thermal insulation layer. The inner core is provided with at least two placed inside the thermal insulation layer, and a protective cover is provided inside the waterproof layer. The protective cover is connected to the top of the waterproof layer. The antifreeze cover is divided into a thermal insulation layer and a waterproof layer from the inside to the outside, and a plurality of detachable inner cores are provided in the thermal insulation layer.

[0004] Compared with the traditional technology, the above device can remove the antifreeze cover on the fruit tree after winter, and the inner core is protected in the antifreeze cover. The removed inner core can be dried and reused, which will not cause waste of resources and pollution. In addition, a protective cover is provided in the waterproof layer. The protective cover is pulled out when in use, and the protective cover is folded into the waterproof layer when not in use, which reduces the cumbersome process of finding materials to wrap the seedlings when protecting the fruit tree seedlings. Despite this, the above device still has great deficiencies in actual use. When the applicant used the above technology to protect the fruit seedlings, it was found that the above device can play a good windproof effect, but when the ambient temperature is low, the above device and the fruit seedlings therein are in a low temperature environment, and the antifreeze effect is poor.

In addition, in order to improve the sealing effect of the sealing assembly and avoid water leakage at the connection between the mounting ring 11 and the blocking block 14, the applicant set a sealing slope 1401 on the bottom side of the blocking block 14. The sealing slope 1401 gradually tilts toward the center of the blocking block 14 along the direction away from the reset spring 13. In this way, the sealing slope 1401 will contact the mounting ring 11, thereby improving the sealing performance.

[0041] When the utility model is used, the staff only needs to attach the two antifreeze units to the trunk of the fruit seedling, and then pass the corresponding lugs 201 through a plurality of bolts 3, and use nuts 4 to cover the bolts 3, so as to realize the installation of the utility model. After installation, the fruit farmer connects the water pipe to the connecting pipe 10, opens the water valve, and at this time, under the action of water pressure, the reset spring 13 is compressed, the block 14 rises, and the water enters the connecting pipe 10, and then passes through the mounting ring 11, the reset spring 13 and the support frame 12 at one time, and enters the cavity 101, so as to realize the filling of the water in the cavity 101. After the filling is completed, the water valve is closed, and the connecting pipe 10 is removed. At this time, the reset spring 13 is reset under the action of elastic force and the gravity of the block 14, and the lower end of the block 14 is inserted into the mounting ring 11, and the sealing slope 1401 is fitted with the mounting ring 11, so as to realize the blocking of the water in the cavity 101, and the water cannot be discharged from the cavity 101.

[0042] After filling the water, the staff inserts the plug 9 into the power socket, and the heating tube 5 heats the water in the cavity 101 under the control of the heating module 7, while ensuring that it is in a constant temperature state. The heat of the water is transferred to the antifreeze plate 1, and the antifreeze plate 1 is transferred to the trunk of the fruit seedling, so as to heat the trunk of the fruit seedling and further prevent the trunk of the fruit seedling from freezing.

[0043] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
