Description

Technical Field

[0001] This utility model relates to the field of fruit tree pruning technology, and more specifically to an agricultural fruit tree pruning tool. Background Technology

[0002] Pruning fruit trees during their growth process stimulates their growth. Pruning tools are used to trim the branches and trunks of fruit trees. Proper pruning makes fruit trees stronger, increasing fruit yield and quality.

[0003] Existing agricultural fruit tree pruning tools often lack adjustable handle height, requiring the use of climbing tools when pruning high branches. This is not only unsafe but also time-consuming and laborious, thus reducing the efficiency of fruit tree pruning. Based on this, this utility model designs an agricultural fruit tree pruning tool to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an agricultural fruit tree pruning tool to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an agricultural fruit tree pruning tool, comprising a housing, a groove at the top of the housing, a set of rotating shafts rotatably connected to the inner wall of one side of the groove, a handle passing through the rotating shafts and fixedly connected thereto, blades fixedly connected to the ends of the handles, a guide groove on the outer wall of the handles, a fixing pin fitting inside the guide groove, a T-shaped plate fixedly connected to the ends of the fixing pins, a sliding plate fixedly connected to the bottom of the T-shaped plate, the sliding plate slidably connected to the inner wall of the housing, and a spring fixedly connected between the top of the sliding plate and the housing, a threaded rod fixedly connected to the bottom of the sliding plate, and a sliding column passing through the threaded rod and threadedly connected thereto.

[0006] Furthermore, the T-shaped plate is fitted to the outer wall of the tool holder, the T-shaped plate passes through the groove, and a through groove is provided at the bottom end of the groove where it connects with the T-shaped plate.

[0007] Furthermore, the inner wall of the housing has grooves on both sides corresponding to the sliding plate, and the sliding plate is located in the groove and slidably connected to it.

[0008] Furthermore, the threaded rod extends through the bottom end of the housing, and a through hole is provided at the connection between the bottom end of the housing and the threaded rod.

[0009] Furthermore, handrails are fixedly connected to both sides of the bottom end of the housing, and a pull ring is fixedly connected to the bottom end of the sliding column.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. When the sliding column is rotated by the pull ring, the sliding column moves downward against the threaded rod, and vice versa, thus realizing the height adjustment of the handle to adapt to fruit tree pruning operations of different heights. This avoids the need to use ladders or other tools to prune branches, making it safer and more user-friendly.

[0012] 2. This utility model allows one hand to hold the handle while the other hand pulls the pull ring downwards, causing the threaded rod, slide plate, T-shaped plate, and fixing pin to move downwards along the slide groove, stretching the spring. As the fixing pin moves downwards along the guide groove, the knife handle rotates downwards around the pivot. Releasing the pull ring allows the slide plate to move upwards along the slide groove under the action of the spring. In other words, the knife handle drives the blade to rotate upwards and ultimately prunes the fruit tree branches, making it more labor-saving and efficient. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The agricultural fruit tree pruning tool involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figures 1-4This utility model provides an agricultural fruit tree pruning tool, including a housing 1. A groove 2 is formed at the top of the housing 1. A set of rotating shafts 15 is rotatably connected to the inner wall of one side of the groove 2. A handle 4 is passed through and fixedly connected to the handle 4. Blades 5 are fixedly connected to both ends of the handle 4. A guide groove 3 is formed on the outer wall of the handle 4. A fixing pin 11 is fitted inside the guide groove 3. A T-shaped plate 6 is fixedly connected to both ends of the fixing pin 11. The T-shaped plate 6 fits against the outer wall of the handle 4 and passes through the groove 2. A through groove 16 is provided at the bottom end of the groove 2 where it connects to the T-shaped plate 6. A sliding plate 14 is fixedly connected to the bottom end of the T-shaped plate 6. The sliding plate 14 is slidably connected to the inner wall of the housing 1. Sliding grooves 12 are provided on both sides of the inner wall of the housing 1 corresponding to the sliding plate 14. The sliding plate 14 is located in the sliding groove 12 and slidably connected to it. A spring 17 is fixedly connected between the top end of the sliding plate 14 and the housing 1. The sliding plate 14, the T-shaped plate 6, and the fixing pin 11 move downward along the sliding groove 12 and stretch the spring 17. The tool holder 4 moves along the guide groove 3 of the fixing pin 11. During the downward movement, the blade 4 rotates downward around the pivot 15. During this process, the fixing pin 11 does not rotate when passing the vertically downward portion of the guide groove 3. When passing the corner of the guide groove 3, the blade 4 rotates downward. When passing the lowest vertical portion of the guide groove 3, the blade 4 stops rotating. The pull ring 9 is released, and under the action of the spring 17, the slide plate 14 drives the T-shaped plate 6 to move upward along the slide groove 12. That is, the blade 4 drives the blade 5 to rotate upward, ultimately pruning the fruit tree branches and trunk, and more effectively... Effortless and efficient, the bottom of the slide plate 14 is fixedly connected to a threaded rod 7, through which a sliding column 8 is threadedly connected. The threaded rod 7 passes through the bottom of the housing 1, and a through hole 13 is provided at the connection between the bottom of the housing 1 and the threaded rod 7. Handrails 10 are fixedly connected to both sides of the bottom of the housing 1. A pull ring 9 is fixedly connected to the bottom of the sliding column 8. When the sliding column 8 is rotated, the sliding column 8 moves downward in contact with the threaded rod 7, and vice versa. This realizes the height adjustment of the handle 4 to adapt to fruit tree pruning operations of different heights.

[0020] The working principle of this utility model is as follows: When the sliding column 8 is rotated by the pull ring 9, the sliding column 8 moves downward against the threaded rod 7; conversely, the sliding column 8 moves upward. This achieves adjustable height of the knife handle 4 to accommodate pruning operations on fruit trees at different heights. During pruning, one hand holds the handle 10, while the other hand pulls the pull ring 9 downward, causing the threaded rod 7, sliding plate 14, T-shaped plate 6, and fixing pin 11 to move downward along the slide groove 12, stretching the spring 17. The knife handle 4 moves downward along the guide groove 3 after the fixing pin 11 has moved. During the process, the blade 4 rotates downward around the pivot 15. When the fixed pin 11 passes the vertically downward part of the guide groove 3, the blade 4 does not rotate. When it passes the corner of the guide groove 3, the blade 4 rotates downward. When it passes the lowest vertical part of the guide groove 3, the blade 4 stops rotating. The pull ring 9 is released, and under the action of the spring 17, the slide plate 14 drives the T-shaped plate 6 to move upward along the slide groove 12. That is, the blade 4 drives the blade 5 to rotate upward and finally prunes the fruit tree branches, which is more labor-saving and efficient.
