Description

Technical Field

[0001] This utility model relates to the field of pine tree pruning technology, and in particular to a branch and leaf pruning device for shaping pine trees. Background Technology

[0002] Ornamental pines are pine trees that have been meticulously pruned and cultivated to display a specific artistic form. They not only possess high ornamental value but are also frequently used in landscaping, garden beautification, and interior decoration. The height of ornamental pines varies depending on the variety, pruning method, and cultivation environment. Generally, they can range from tens of centimeters to several meters. Common ornamental pines such as black pines and white pines, after styling and pruning, typically reach a height between 1 and 3 meters, but some specially pruned ornamental pines can achieve even greater heights.

[0003] With the development of technology, the shaping of pine trees has gradually shifted from manual pruning to mechanical pruning. For example, document CN208338367U discloses a convenient shaping and pruning device for Podocarpus macrophyllus seedlings, which includes a box, handle, controller, and battery. It adopts a mechanical method for shaping and pruning, which improves the efficiency of pruning work and saves manpower and material resources. The pruning device uses electricity instead of diesel, which protects the environment. The pruning device is small in size, easy to carry, and easy for workers to use.

[0004] The aforementioned existing technologies still have the following shortcomings in practical use:

[0005] 1. During the pruning of branches and leaves of shaped pines, some debris will be generated. The debris will fall to the ground and require extra time to clean up. In addition, the debris will prevent the staff holding the pruning device from opening their eyes, which will delay the pruning work efficiency.

[0006] 2. Do not store the trimmer blades after use. The trimmer blades will always be exposed and may easily scratch workers or be damaged by collision with the ground.

[0007] 3. The length of the connecting rod is fixed. Since the height of the pine trees varies, a fixed length of connecting rod will make it inconvenient to trim some of the taller pine trees, and will also make it inconvenient to use. Utility Model Content

[0008] The purpose of this utility model is to solve the problems existing in the prior art by proposing a pruning device for shaping pine trees.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A pruning device for shaping pines includes a pruning mechanism, a connecting rod assembly, and a storage assembly;

[0011] The trimming mechanism includes a receiving box, a trimming motor, and a trimming blade. A sliding platform is provided inside the receiving box. The trimming motor is mounted on top of the sliding platform, and the trimming blade is mounted on the trimming motor. The trimming blade has a retracted state and a working state. In the retracted state, the trimming blade is located inside and covered by the receiving box. In the working state, the trimming blade moves to the outside of the receiving box. The connecting rod assembly includes a fixed rod and a movable rod. The bottom end of the movable rod is inserted into the fixed rod and can move up and down. The receiving box is fixedly connected to the top end of the movable rod. The receiving assembly includes several upper arms hinged to the bottom of the receiving box and arranged in a circumferential array around the movable rod. A ring is sleeved on the outer side of the movable rod. Lower arms are hinged between the ring and the upper arms. A receiving net is fixedly provided on the outer side of the ring, and the outer ring of the receiving net is connected to the several lower arms.

[0012] Preferably, an internally threaded tube (305) is installed on the inner side of the ring (302). The internally threaded tube (305) is rotatable between the ring (302) and the ring (302) through a bearing. The outer wall of the moving rod is provided with two sets of externally threaded sections, one up and one down. The internally threaded tube can be threadedly connected to the two externally threaded sections respectively when moving up and down.

[0013] Preferably, the bottom of the receiving box has two through slots, one of which has a screw rotatably mounted therein, and the other has a slide rod fixedly connected therein. A moving block is threaded onto the outer wall of the screw, and a slider is slidably mounted on the outer wall of the slide rod. The sliding platform is fixedly connected between the moving block and the slider.

[0014] Preferably, a gear I is fixedly sleeved on the outer wall of the screw, and a gear II is fixedly connected to the upper arm that matches the position of the gear I. The gear II rotates with the upper arm and meshes with the gear I.

[0015] Preferably, the length of the lower arm is greater than the length of the upper arm, and when the upper arm is adjusted to a horizontal state, the storage net is unfolded and the unfolded area is greater than the cross-sectional area of ​​the container.

[0016] Preferably, a lead screw is rotatably mounted on the inner bottom wall of the fixed rod, and a threaded sleeve is threaded onto the outer wall of the lead screw. The threaded sleeve is fixedly connected to the inner side of the moving rod, and the bottom end of the lead screw passes through the fixed rod and is fixedly sleeved with a throttle handle.

[0017] Preferably, the outer wall of the movable rod has two symmetrically distributed limiting grooves, the top end of the fixed rod is fixedly connected to the limiting plate, the top end of the lead screw is rotatably engaged with the limiting plate, and the two sides of the limiting plate pass through the two limiting grooves and are slidably engaged.

[0018] Preferably, the lead screw, fixed rod, and moving rod are all hollow structures, and the bottom of the receiving box has a through hole communicating with the moving rod.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. In this utility model, the storage net is unfolded by the folding of the upper and lower arms through the cooperation of the internal threaded tube and the two external threaded sections. This realizes the function of the storage net to collect branches and leaves during pruning, which not only facilitates subsequent cleaning, but also avoids the obstruction of the staff's vision by the debris, thus improving work efficiency.

[0021] 2. In this utility model, while the storage net is unfolded, the screw rotates through the cooperation of gear II and gear I, which in turn drives the moving block to move the sliding table, so that the trimming blade moves out synchronously, and vice versa. This effectively avoids the exposure of the trimming blade when it is not in use, and prevents the risk of scratches and collision damage.

[0022] 3. In this utility model, the distance between the fixed rod and the moving rod can be flexibly adjusted by the threaded transmission of the lead screw and the lead sleeve, and by the cooperation of the limiting plate and the limiting groove, so as to adapt to the pruning needs of different heights of pine trees and enhance the flexibility and adaptability of use.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] like Figure 1-6 As shown, this utility model provides a pruning device for shaping pine branches and leaves, including a pruning mechanism 100, a connecting rod assembly 200, and a storage assembly 300;

[0033] The trimming mechanism 100 includes a receiving box 101, a trimming motor 102, and a trimming blade 103. A sliding table 104 is provided inside the receiving box 101. The trimming motor 102 is mounted on top of the sliding table 104, and the trimming blade 103 is mounted on the trimming motor 102. The trimming blade 103 has a retracted state and a working state. In the retracted state, the trimming blade 103 is located inside and covered by the receiving box 101. In the working state, the trimming blade 103 moves to the outside of the receiving box 101. The connecting rod assembly 20... The 0 includes a fixed rod 201 and a movable rod 202. The bottom end of the movable rod 202 is inserted into the fixed rod 201 and can move up and down. The receiving box 101 is fixedly connected to the top end of the movable rod 202. The storage assembly 300 includes a plurality of upper arms 301 that are hingedly installed at the bottom of the receiving box 101 and distributed in a circumferential array around the movable rod 202. A ring 302 is sleeved on the outside of the movable rod 202. A lower arm 303 is hingedly installed between the ring 302 and the upper arms 301. A storage net 304 is fixedly provided on the outside of the ring 302. The outer ring of the storage net 304 is connected to the plurality of lower arms 303.

[0034] In this embodiment, an internally threaded tube 305 is installed on the inner side of the ring 302. The internally threaded tube 305 is rotatable between the ring 302 and the ring 302 through a bearing. Two sets of externally threaded sections 203, one above the other, are provided on the outer wall of the moving rod 202. The internally threaded tube 305 can be threadedly connected to the two externally threaded sections 203 respectively when moving up and down. Through the connection between the internally threaded tube 305 and the two externally threaded sections 203, the unfolding and storage of the storage net 304 can be realized.

[0035] In this embodiment, the bottom of the receiving box 101 has two through slots 105. A screw 106 is rotatably disposed in one through slot 105, and a slide rod 107 is fixedly connected in the other through slot 105. A moving block 108 is threadedly connected to the outer wall of the screw 106, and a slider 109 is slidably disposed on the outer wall of the slide rod 107. A sliding platform 104 is fixedly connected between the moving block 108 and the slider 109. The rotation of the screw 106 drives the moving block 108 to move the sliding platform 104. The sliding platform 104 moves stably with the cooperation of the slider 109 and the slide rod 107, thereby removing the trimming tool 103 from the receiving box 101.

[0036] In this embodiment, a gear I 110 is fixedly sleeved on the outer wall of the screw 106, and a gear II 306 is fixedly connected to the upper arm 301 that matches the position of the gear I 110. The gear II 306 rotates with the upper arm 301 and meshes with the gear I 110. The rotation of the screw 106 is achieved through the cooperation of the gear II 306 and the gear I 110.

[0037] In this embodiment, the length of the lower arm 303 is greater than the length of the upper arm 301. When the upper arm 301 is adjusted to a horizontal state, the storage net 304 is unfolded and the unfolded area is greater than the cross-sectional area of ​​the container box 101. The unfolded storage net 304 can collect the pruned branches and debris.

[0038] In this embodiment, a lead screw 204 is rotatably mounted on the inner bottom wall of the fixed rod 201, and a threaded sleeve 205 is threadedly connected to the outer wall of the lead screw 204. The threaded sleeve 205 is fixedly connected to the inner side of the movable rod 202. The bottom end of the lead screw 204 passes through the fixed rod 201 and is fixedly sleeved with a throttle 206. The throttle 206 drives the lead screw 204 to rotate, and the lead screw 204 drives the threaded sleeve 205 to move the movable rod 202 through threaded transmission, thereby realizing the distance span between the fixed rod 201 and the movable rod 202.

[0039] In this embodiment, two symmetrically distributed limiting grooves 207 are provided on the outer wall of the movable rod 202. The top end of the fixed rod 201 is fixedly connected to the limiting plate 208. The top end of the lead screw 204 is rotatably engaged with the limiting plate 208. The two sides of the limiting plate 208 pass through the two limiting grooves 207 and are slidably engaged. The limiting plate 208 supports the top end of the lead screw 204, making the lead screw 204 rotate stably and allowing the movable rod 202 to move linearly up and down.

[0040] In this embodiment, the lead screw 204, the fixed rod 201, and the moving rod 202 are all hollow structures. The bottom of the receiving box 101 is provided with a through hole 111 that communicates with the moving rod 202. The wire that supplies power to the trimming motor 102 can pass through the lead screw 204, the moving rod 202, and the through hole 111 into the receiving box 101.

[0041] How to use and how to work this device:

[0042] When using this device, firstly, according to the height of the trimmed pine, the screw 204 is rotated by adjusting the throttle 206. The rotation of the screw 204 will drive the threaded sleeve 205 to move the moving rod 202 through the threaded transmission. The moving rod 202 moves linearly with the cooperation of the limiting plate 208 and the limiting groove 207. The overall length can be adjusted to adapt to the height of the trimmed pine, making it more convenient to use and more adaptable.

[0043] Before trimming, the internally threaded tube 305 is separated from the lower externally threaded section 203. Then, the internally threaded tube 305 is connected to the upper externally threaded section 203. During this process, the internally threaded tube 305 drives the ring 302 to move upward. The ring 302 causes the lower arm 303 to push the upper arm 301. The upper arm 301 and the lower arm 303 are folded together, and the storage net 304 covering the lower arm 303 is unfolded. The trimmed branches and debris will fall into the storage net 304 as much as possible for centralized treatment, and the problem of debris affecting the staff's vision will be avoided as much as possible.

[0044] When folding between the lower arm 303 and the upper arm 301, the upper arm 301 deflects around the hinge point, causing gear II 306 to rotate. When gear II 306 rotates, it drives gear I110 to drive screw 106 to rotate. The rotation of screw 106 drives moving block 108 to move sliding table 104. Sliding table 104 moves stably with the cooperation of slider 109 and sliding rod 107, so as to remove the trimming tool 103 from the receiving box 101. The unfolding of the storage net 304 and the removal of the trimming tool 103 are synchronized. Conversely, when the storage net 304 is reset, the trimming tool 103 will return to the receiving box 101, so as to store the trimming tool 103 and prevent the trimming tool 103 from being exposed when not in use, thereby preventing scratches to workers or damage from collisions with the ground.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
