[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary industry and is the basic industry that supports the construction and development of the national economy. Agriculture includes crop cultivation, which includes the cultivation of fruit trees.

[0003] In fruit tree cultivation, frost protection is necessary during winter. This treatment reduces the damage caused by low temperatures, protects the normal physiological functions and growth of the fruit trees, and ensures the yield and quality of the following year. Specific measures for frost protection include fertilization, whitewashing the trunk, and wrapping and covering.

[0004] Whitewashing tree trunks involves applying a white coating to the trunk with materials such as lime water. This reflects sunlight, reduces temperature fluctuations, prevents bark cracking, and also helps prevent insects and diseases. The process involves applying an antifreeze material to the trunk surface with a brush. However, due to the uneven surface of fruit trees, the current method still relies on manual application, leading to low efficiency and inconsistent thickness. Applying too thickly can impede the tree's respiration, while applying too thinly fails to provide antifreeze protection, further complicating the application process. Summary of the Invention

[0050] Please see Figures 1-8 This embodiment provides a fruit tree antifreeze protection device and method, including a first arc plate 11 and a second arc plate 12, which are adapted to each other and can form a complete ring to encircle the fruit tree. Each arc plate 11 and the second arc plate 12 is equipped with a telescopic rod that abuts against the surface of the fruit tree, limiting the position of the arc plate 11 and the second arc plate 12. It also includes a coating component for coating the fruit tree surface. The coating component includes a coating brush 22 and a scraper 23. Furthermore, it includes a pretreatment component. When the coating brush 23 is in operation, the pretreatment component is driven to form a path. When the coating brush 22 passes over uneven areas of the fruit tree surface, it moves according to the path of the pretreatment component to adaptively adjust, thereby ensuring uniform coating of the tree surface.

[0051] In a further embodiment of the present invention, two limiting plates 14 and a rotating assembly for driving the two limiting plates 14 to rotate are also included. When the coating assembly moves to the bottom, the rotating assembly drives the limiting plates 14 to rotate, thereby driving the coating assembly to rotate, so that the coating assembly rotates to the uncoated area. The bottom of each of the two limiting plates 14 is rotatably connected with a fixing ring 15.

[0052] A screw 13 is rotatably mounted on the first arc-shaped plate 11, and two limiting plates 14 are also included. The screw 13 is rotatably mounted in one of the limiting plates 14. Both limiting plates 14 are arc-shaped and can be assembled into a complete ring.

[0054] In the embodiments provided by the present invention, the pretreatment component includes two fixed plates 31 fixed on the first arc-shaped plate 11 and the limiting plate 14. A plurality of sliding rods 32 are slidably arranged inside the fixed plate 31. A guide rod 33 is slidably arranged inside the sliding rod 32. The end of the guide rod 33 passes through the sliding rod 32 and is fixedly connected to a friction plate 34. The friction plate 34 abuts against the inner wall of the fixed plate 31. The friction plate 34 abuts against and limits the fixed plate 31, thereby limiting the sliding rod 32.

[0055] Furthermore, the pretreatment assembly also includes a wedge-shaped rod 35 slidably disposed within the sliding rod 32, and a guide hole 36 adapted to the two wedge-shaped rods 35 is provided on the guide rod 33, with a support spring 37 fixedly connected to the bottom end of the guide rod 33.

[0056] Furthermore, a protrusion 38 is fixedly connected to the outside of the sliding rod 32, and a connecting rod 39 is slidably disposed inside the protrusion 38 and fixedly connected to the inner wall of the sliding rod 32. Two return springs 391 are sleeved on the connecting rod 39 and are disposed on both sides of the protrusion 38. The return springs 391 are not connected to the protrusion 38.

[0057] Locking mechanisms are provided between the first arc-shaped plate and the second arc-shaped plate, the two limiting plates, and the two fixing rings for mutual fixation.

[0058] In a further embodiment of the present invention, the rotating assembly includes two arc-shaped racks 41 fixed within two limiting plates 14. The two arc-shaped racks 41 are combined to form a complete annular rack. A rotating tube 42 is rotatably connected within the limiting plates 14. A torsion spring connected to the inner wall of the limiting plates 14 is provided on the rotating tube 42. The rotating tube 42 is reset after rotation.

[0059] Specifically, the rotating assembly also includes a drive rod 44 slidably disposed at the bottom of the threaded block 21. A guide block 45 is fixedly connected to the outside of the drive rod 44. A guide groove 46 adapted to the guide block 45 is opened inside the rotating tube 42. The guide groove 46 is composed of a spiral groove and a straight groove. When the guide block 45 moves in the spiral groove, it drives the rotating tube 42 to rotate, causing the arc-shaped rack 41 to drive the limiting plate 14 to rotate, causing the coating brush 22 to rotate around the fruit tree as the center. A one-way plate is rotatably connected inside the guide groove 46. The one-way plate only rotates upward for guidance, so that when the guide block 45 moves downward, it moves in the spiral groove, and when the guide block 45 moves upward, it moves in the straight groove.

[0060] In this invention, a steering component is also included. When the coating component moves to the bottom, the steering component drives the coating brush 22 to turn so that the fruit tree is coated evenly.

A connecting rope 53 is connected between the spur rack 52 and the drive rod 44. An abutment spring 54 is provided on the connecting rope 53.

[0061] Specifically, a limiting rod 16 is fixedly connected to the second arc-shaped plate 12, and the limiting rod 16 is fixedly connected to the limiting plate 14.

[0062] In this invention, a method for protecting fruit trees from frost is provided, which is used in any of the fruit tree frost protection devices. The protection method of the fruit tree frost protection device includes the following steps: S1: The surface of the fruit tree is initially cleaned by moving the scraper 23, and the fruit tree is coated by moving the coating brush 22; S2: The scraper 23 forms a path on the uneven surface of the fruit tree, and drives the coating brush 22 to move according to the path to coat the entire surface of the fruit tree; S3: After the coating brush 22 moves to the bottom, it rotates to coat the bottom of the fruit tree; S4: After the coating brush 22 moves to the bottom and rotates, it is driven to switch positions around the trunk.

[0063] When protecting fruit trees from freezing, the first arc plate 11, the second arc plate 12, and the fixing ring 15 are placed on the outside of the fruit tree and assembled into a complete circle. A motor is installed inside the first arc plate 11, and the output end of the motor is fixedly connected to the screw 13. The appropriate position of the coating brush 22 and the scraper 23 in contact with the surface of the fruit tree is adjusted. Then, the motor is driven to rotate the first screw 13, causing the threaded plate to move down, which in turn moves the coating brush 22 and the scraper 23 down. At the same time, the coating brush 22 is connected to the antifreeze liquid, which is pumped onto the surface of the fruit tree and evenly coated by the coating brush 22.

[0064] When the scraper 23 encounters an uneven area on the fruit tree surface, it pushes the scraper 23 to move, causing the round rod 25 to move synchronously, thereby pushing the wedge rod 35 to move, driving the guide rod 33 to move downward, causing the friction plate 34 to move out of the fixed plate 31, and driving the round rod 25 to move until the round rod 25 moves out of the sliding rod 32. The guide rod 33 is then pushed upward by the support spring 37, causing the friction plate 34 to move upward and fix the sliding rod 32. According to the movement of the scraper 23, a path is formed on multiple sliding rods 32.

[0065] When the coating brush 22 moves down to the path formed by the sliding rod 32, the round rod 25 pushing the coating brush 22 moves across the path. When the round rod 25 moves across the sliding rod 32, the friction plate 34 is unlocked by the wedge rod 35, so that the sliding rod 32 moves to the initial position.

[0066] When the sliding brush moves to the bottom, the resistance at the bottom of the drive rod 44 is greater than the resistance at the top. When the drive rod 44 contacts the rotating tube 42, it pushes the drive rod 44 to move into the threaded plate, thereby causing the pull rope to pull the rack 52 down, driving the sector gear 51 to rotate, and driving the coating brush 22 to rotate to a vertical position.

[0067] When the drive rod 44 contacts the top of the inner wall of the threaded plate, the drive rod 44 will move and drive the guide block 45 to move into the guide groove 46, drive the rotating tube 42 to rotate, thereby causing the first gear 43 to rotate synchronously, driving the arc rack 41 to rotate, thereby driving the limiting plate 14 to rotate, and driving the coating brush 22 to move to the uncoated area. During the movement, the area at the bottom of the fruit tree is coated. Then, the screw 13 is driven by the motor to rotate in the opposite direction, driving the threaded plate to move upward to the initial state, and repeating the above operation.

[0068] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
