Description

Technical Field

[0001] This utility model relates to the field of cold protection technology, specifically to a protective tool for preventing late spring frost damage to dried apricot trees. Background Technology

[0002] In Xinjiang, regions like southern Xinjiang, with their abundant sunshine and large diurnal temperature range, have become important production areas for dried apricots grown on trees. The dried apricot industry is an important part of the local agricultural economy, playing a vital role in ensuring farmers' income and promoting regional agricultural development. However, Xinjiang's spring climate fluctuates greatly, with frequent late spring frosts. Due to geographical factors, some planting areas experience large temperature drops and long durations during late spring frosts, which can easily cause frost damage to the trunks and new branches of dried apricot trees. In severe cases, this can lead to weakened tree growth and reduced fruit yield, directly threatening the stable development of Xinjiang's dried apricot industry. A frost protection device for fruit trees, disclosed in patent CN220571155U, can wrap and heat the trunk neck of fruit trees, preventing frost damage to some extent. However, this device has significant drawbacks and is insufficient to meet the protection needs of dried apricots grown on trees in Xinjiang. Firstly, the length of the cylinder used to wrap the trunk is fixed. In Xinjiang's dried apricot cultivation, the trunk height varies with tree age, and the fixed-length cylinder cannot flexibly adjust the wrapping height according to actual needs. This may result in the protection area not fully covering the protected parts, or excessive height leading to resource waste. This device uses springs to provide clamping force to the fruit trees. However, in Xinjiang's tree-grown apricot cultivation, some young trees have thin trunks, resulting in insufficient spring deformation and difficulty in generating sufficient clamping force. This can easily lead to the device loosening or shifting during use due to factors such as wind, making it unable to stably adhere to the tree trunk for effective wrapping and heating. Ultimately, this affects the device's effectiveness in protecting against late spring frost damage to tree-grown apricots in Xinjiang. Consequently, the existing device still falls short in terms of applicability and reliability in protecting tree-grown apricots from late spring frost damage in Xinjiang, failing to meet the actual protection needs of the local area. Therefore, there is an urgent need for a protective tool for preventing late spring frost damage to tree-grown apricots. Utility Model Content

[0017] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes a heat insulation film 1 and a clamping plate 2. The heat insulation film 1 is wrapped around the root neck of the tree trunk. Four clamping plates 2 are evenly rounded on the upper and lower sides of the outer side of the heat insulation film 1. Rubber pads 13 are fixedly installed on the clamping plates 2, and the rubber pads 13 are in contact with the heat insulation film 1.

Heating plate 6, there are four heating plates 6, which are respectively fixed on the inner arc wall of four clamping plates 2. A detachable storage battery 7 is provided on the connecting half ring 4 on the lower left side. The storage battery 7 is electrically connected to the heating plate 6. The connecting half rings 4 on the left and right sides are connected by a convenient loading and unloading mechanism 8. The protective film 9 is fixedly installed in the two connecting half-rings 4 at the top, and a pull rope 10 is movably threaded through the protective film 9; The clamping force adjusting mechanism 5 includes: The movable rod 5-1 is fixedly mounted on the side wall of the clamping plate 2 and movably passes through the connecting half ring 4. An adjusting screw 5-2 is inserted into the movable rod 5-1 through a bearing. Guide rods 11 are fixedly mounted on the side wall of the clamping plate 2 on both the upper and lower sides of the movable rod 5-1 and movably pass through the connecting half ring 4. The guide rods 11 can guide the movement of the clamping plate 2, thereby ensuring the stability of the clamping plate 2. A contact plate 12 is fixedly mounted on one end of the guide rod 11 and is engaged with the outer arc wall of the connecting half ring 4. The contact plate 12 can limit the extreme movement position of the guide rod 11 and prevent the guide rod 11 from detaching from the connecting half ring 4. An internal thread adjusting block 5-3 is movably disposed within a movable rod 5-1, and the internal thread adjusting block 5-3 is sleeved on an adjusting screw 5-2 by thread rotation. A limiting ring 5-4 is movably sleeved on the movable rod 5-1, and the limiting ring 5-4 is fixedly sleeved on the internal thread adjusting block 5-3. Spring 5-5 is movably sleeved on movable rod 5-1. Both ends of spring 5-5 are fixedly connected to limiting ring 5-4 and inner wall of connecting half ring 4, respectively. After clamping plate 2 clamps the fruit tree, the position of internal thread adjusting block 5-3 can be changed by adjusting screw 5-2, and the compression degree of spring 5-5 can be changed, thereby adjusting the clamping force of clamping plate 2 on fruit tree. When encountering thinner sapling trunks, the clamping stability of clamping plate 2 can still be guaranteed. The convenient loading and unloading mechanism 8 includes: Connecting block 8-1, there are two connecting blocks 8-1, which are fixedly set on the connecting half ring 4 on the left and right sides respectively. Two slots 8-2 are opened on the front side wall of the right connecting block 8-1. Insert rod 8-3 is movably inserted into the slot 8-2. Movable plate 8-4 connected to the rear end of the insert rod 8-3 is movably set in the slot 8-2. The limiting plate 8-5 is abutting against the front side wall of the two connecting blocks 8-1. The front end of the insertion rod 8-3 is fixedly connected to the limiting plate 8-5. The left connecting block 8-1 has a limiting groove 8-6 that cooperates with the limiting plate 8-5. The insertion rod 8-3 is movably sleeved with a second spring 8-7. The two ends of the second spring 8-7 are fixedly connected to the movable plate 8-4 and the inner wall of the slot 8-2, respectively. The convenient loading and unloading mechanism 8 can realize the convenient connection or disassembly of the connecting half ring 4 on the left and right sides, so as to improve the convenience of tool installation on fruit trees.

[0018] When using this utility model, first wrap the heat insulation film 1 around the trunk neck of the fruit tree, then place the two connecting half rings 4 at the bottom on the ground on the left and right sides of the fruit tree. Then move the upper connecting half rings 4 upward to a suitable height, and the folding cover 3 will be stretched accordingly. Then merge the connecting half rings 4 on the left and right sides. During this process, the tension applied by the second spring 8-7 to the limiting plate 8-5 can realize the locking of the limiting plate 8-5 and the limiting groove 8-6, ensuring the connection limit of the connecting half rings 4 on the left and right sides. At the same time, the clamping plate 2 will also come into contact with the heat insulation film 1, and the first spring 5-5 will be compressed, realizing the clamping and fixing of the heat insulation film 1 by the clamping plate 2. Then the two ends of the pull rope 10 can be tied so that the protective film 9 can close the two connecting half rings 4 at the top. During the protection process, the heating plate 6 can also be activated to ensure the cold protection effect on the fruit tree. If the trunk of the young tree is thin, the adjusting screw 5-2 can be rotated to make the internal thread adjusting block 5-3 drive the limiting ring 5-4 to move, increase the compression of the first spring 5-5, and increase the clamping force of the clamping plate 2 to ensure the stability of the tool on the fruit tree.

[0019] Compared with the prior art, the beneficial effects of this utility model are: By cooperating with the adjusting screw 5-2, the internal thread adjusting block 5-3 and the limiting ring 5-4 in the clamping force adjusting mechanism 5, the compression degree of the first spring 5-5 can be changed, thereby adjusting the clamping force of the clamping plate 2 on the insulation film 1 and the trunk neck of the fruit tree. Even for thinner saplings, the clamping stability of the tool on the fruit tree is guaranteed, effectively solving the problem of insufficient clamping force of the existing device on thin trunks. With the help of the connecting block 8-1, the insert rod 8-3, and the second spring 8-7 in the convenient loading and unloading mechanism 8, when the connecting half rings 4 on the left and right sides are joined, the second spring 8-7 pulls the limiting plate 8-5 into the limiting groove 8-6 to complete the fixation. When disassembling, the limiting can be quickly released. At the same time, the connecting half ring 4 can be moved up and down to adjust the height. The folding cover 3 is stretched and adapted accordingly, which greatly simplifies the process of installing and adjusting the height of the tool on the fruit tree and improves the convenience of operation. By using the folding cover 3 to connect the semi-ring 4 for height adjustment, the height of the wrapping protection can be adjusted according to needs, avoiding insufficient protection or waste of resources caused by a fixed height; The rubber pad 13 on the clamping plate 2 can increase the friction with the insulation film 1 and improve the clamping stability.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
