Description

Technical Field

[0001] This utility model relates to the field of tea garden pruning machine technology, specifically to a tea garden contour pruning machine with an arc-shaped blade assembly. Background Technology

[0002] Tea garden pruning is an important part of the tea production process. Proper pruning can promote the growth of tea trees and improve the yield and quality of tea. Currently, tea garden pruning machines are usually used in tea garden pruning operations.

[0003] Utility model patent CN218998940U discloses a tea garden tea tree pruning machine, belonging to the field of tea tree pruning technology. The tea garden tea tree pruning machine includes a trolley and a push rod located at the rear of the trolley. A telescopic motor is vertically mounted on the trolley at the front end of the push rod, and a pruning device is mounted above the telescopic motor. A dust collection box is mounted on the trolley at the front end of the pruning device. The dust collection box has an inlet and an outlet at its upper and lower ends, respectively. A fixed frame is horizontally mounted on the upper part of the dust collection box, and an exhaust fan is installed inside the fixed frame. An outlet is located on the front wall of the dust collection box, and a hinged door is attached to the outlet. A latching device is located at the upper end of the door. This utility model can collect pruned tea leaves through the dust collection box, reducing the amount scattered on the tea trees and affecting their photosynthesis. It can also absorb dust and leaves generated during cutting, reducing harm to tea farmers.

[0004] There are many types of pruning machines on the market, but most commonly used pruning machines use straight blade sets. However, there are some problems with this type of pruning machine in actual use. On the one hand, straight blade sets are difficult to conform to the arc-shaped crown outline formed by the natural growth of tea trees, resulting in uneven tops of tea trees after pruning, which affects the photosynthesis and ventilation of tea trees, and thus has an adverse effect on the yield and quality of tea.

[0005] On the other hand, some existing pruning machines lack an effective contour-following structure, making it impossible to automatically adjust the pruning height and angle according to different tea tree growth patterns. In complex tea garden environments, this can easily lead to over-pruning or under-pruning, affecting the effectiveness of the machine. Therefore, we propose a contour-following pruning machine for tea gardens using an arc-shaped blade assembly. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-3 This utility model provides a technical solution: a tea garden contour pruning machine with an arc-shaped blade assembly, including a crossbeam plate 1 installed on an external pruning vehicle. Two symmetrical first hydraulic cylinders 10 are fixedly installed on the crossbeam plate 1. Guide rails 12 are detachably installed at the ends of the telescopic shafts of the two first hydraulic cylinders 10, so that the height of the guide rails 12 can be flexibly adjusted according to the height of different tea trees. When facing tea trees of different heights, the operator can control the extension and retraction of the first hydraulic cylinders 10 to drive the guide rails 12 to rise and fall, thereby adjusting the height of the entire pruning mechanism, ensuring that the pruning work can be carried out accurately, and improving the adaptability of the pruning machine to different tea trees.

[0028] In this embodiment, a second hydraulic cylinder 2 is fixedly installed at the end of the guide rail 12. An arc plate 24 is provided on the telescopic shaft of the second hydraulic cylinder 2, so that the arc plate 24 can move in the horizontal direction. During the pruning process, the second hydraulic cylinder 2 can push the arc plate 24 to move left and right according to the width and shape of the tea tree, so that the pruning mechanism can better fit the outline of the tea tree, avoid pruning blind spots, and further improve the accuracy and comprehensiveness of pruning.

[0029] Specifically, a lower panel 251 is provided at the center of the lower part of the arc-shaped plate 24. The lower panel 251 is fixed to the arc-shaped plate 24 by two symmetrical fixing rods 25. The two ends of the fixing rods 25 are respectively fixed to the lower panel 251 and the arc-shaped plate 24. Multiple side hinge plates 26 are provided on both sides of the lower panel 251. The side hinge plates 26 are hinged to the lower panel 251 and to adjacent side hinge plates 26. The side hinge plates 26 are connected by a third hydraulic cylinder 261. The drive is used for angle adjustment. A drive motor 27 is fixedly installed on both the lower panel 251 and the side hinge plate 26. A short shaft 271 is fixedly installed at the end of the output shaft of the drive motor 27. A set of pruning blades 273 is detachably installed on the short shaft 271. The third hydraulic cylinder 261 can flexibly adjust the angle of the side hinge plate 26 according to the undulation of the tea tree surface, so that the pruning blades 273 always maintain a suitable distance and angle with the tea tree surface, ensuring that the top of the pruned tea tree is flat and effectively improving the growth environment of the tea tree.

[0030] like Figure 1As shown, a fixed support 11 is fixedly installed at the end of the telescopic shaft of the first hydraulic cylinder 10, and the guide rail 12 is detachably installed on the bottom surface of the fixed support 11 by multiple fastening bolts, which facilitates the fixed installation and disassembly operations.

[0031] like Figure 1 As shown, a horizontally arranged guide rod 13 is fixedly installed between the left and right side plates of the guide rail 12. Two symmetrical columns 21 are fixedly installed on the top surface of the arc plate 24. A sliding sleeve 22 is fixedly installed at the top of the column 21. The sliding sleeve 22 is fitted onto the column 21 and slidably connected to the column 21. The cross-section of the sliding sleeve 22 and the guide rod 13 are both rectangular. The size of the sliding sleeve 22 is adapted to the size of the guide rod 13. The rectangular cross-section and the adapted size of the sliding sleeve 22 and the guide rod 13 can effectively limit the shaking of the arc plate 24, ensure the precise position of the trimming blade 273 during cutting, and improve the stability and quality of the trimming operation.

[0032] like Figure 2 As shown, a fixed base 20 is fixedly installed at the end of the telescopic shaft of the second hydraulic cylinder 2. One of the columns 21 is detachably installed on the fixed base 20 by multiple fastening bolts, making the connection between the arc plate 24 and the second hydraulic cylinder 2 more stable and easier to disassemble. The stable connection ensures that the arc plate 24 will not fall off during movement, while the detachable design provides convenience for equipment maintenance or component replacement, reducing maintenance difficulty and time cost.

[0033] like Figure 2 As shown, a linkage rod 23 is fixedly installed between the two sliding sleeves 22. The base of the third hydraulic cylinder 261 is hinged to the inner side of the arc plate 24, and the end of the telescopic shaft of the third hydraulic cylinder 261 is hinged to the corresponding side hinge plate 26. The linkage rod 23 ensures that the two sliding sleeves 22 move synchronously, thereby enabling the third hydraulic cylinder 261 to stably drive the side hinge plate 26, ensuring that the entire pruning mechanism moves smoothly when adapting to the shape of the tea tree, thus improving pruning efficiency and effect.

[0034] like Figure 3 As shown, a fixing sleeve 272 is fixedly installed at the center of each group of multiple trimming blades 273. The fixing sleeve 272 is detachably installed on the short shaft 271 by fastening bolts. When the trimming blades 273 are worn, the operator can quickly unscrew the fastening bolts, remove the old blades and install new blades, reducing equipment downtime. It also makes it easy to replace blades of different specifications according to different trimming needs, thus enhancing the practicality of the trimming machine.

[0035] Finally, it should be noted that the components involved in this utility model, such as the first hydraulic cylinder 10, the second hydraulic cylinder 2, the third hydraulic cylinder 261, and the drive motor 27, are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0036] When using the arc-shaped blade assembly tea garden contour pruning machine of this utility model, first install the pruning machine on an external pruning vehicle. According to the approximate height of the tea trees in the tea garden, operate the first hydraulic cylinder 10 on the crossbeam plate 1, and drive the fixed support 11 and guide rail 12 to rise and fall through the telescopic shaft to adjust the pruning mechanism to a suitable height.

[0037] After entering the tea garden, the second hydraulic cylinder 2 is activated. According to the width and shape of the tea tree, the arc plate 24 is pushed to move horizontally along the guide rod 13 so that the pruning mechanism initially fits the outline of the tea tree. At the same time, the third hydraulic cylinder 261 starts to work. According to the actual undulation of the tea tree surface, the angle of the side hinge plate 26 is flexibly adjusted to ensure that the pruning blades 273 on the lower panel 251 and the side hinge plate 26 maintain the best distance and angle with the tea tree surface.

[0038] Turn on the drive motor 27 to drive the short shaft 271 and the trimming blade 273 to rotate at high speed for trimming. If the trimming blade 273 is worn, unscrew the fastening bolt on the fixing sleeve 272 to quickly replace the blade and ensure that the trimming work continues to be carried out efficiently.
