Description

Technical Field

[0001] This application relates to the field of municipal engineering technology, specifically a municipal landscaping tree trimming device. Background Technology

[0002] In municipal management, trees in green belts need to be pruned regularly to ensure that the trees are neat and beautiful. During the pruning process, pruning vehicles are used to trim the branches and leaves of the trees.

[0003] Chinese utility model patent CN221128033U discloses a rapid pruning device for municipal garden trees. This pruning device consists of a branch and leaf collection platform and a lateral drive mechanism to collect pruned branches and leaves. However, the collection platform and tilting guard only form an L-shape to guide the branches and leaves into the carriage of the mobile vehicle. There are no baffles on either side of the collection platform, so after collecting the branches and leaves, wind blowing across the platform causes the pruned branches and leaves to slide off the top, affecting the continuous collection of pruned branches and leaves.

[0004] Therefore, this application provides a municipal garden tree trimming device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a municipal garden tree pruning device, which aims to solve the problems mentioned in the background art of existing pruning devices, such as the wind blowing across the branch and leaf collection platform, causing the pruned branches and leaves to fall and affecting the collection effect.

[0006] To achieve the above objectives, this application provides the following technical solution: a municipal garden tree pruning device, comprising a pruning robotic arm and a moving vehicle disposed at the bottom end of the pruning robotic arm for moving the pruning robotic arm;

[0007] To facilitate the collection of pruned branches and leaves: the bottom of the mobile vehicle is provided with a collection component for collecting pruned branches and leaves, one side of the collection component is provided with a drive component for moving the collection component, and the other side of the collection component is provided with a guide for guiding the movement of the collection component; the collection component includes a collection box, the top of the collection box is provided with a storage groove for storing branches and leaves, the end of the storage groove away from the mobile vehicle is a first inclined surface, and the bottom end of the inner wall of the storage groove is a second inclined surface. Before the pruning robotic arm begins pruning, the drive rod is controlled to move the collection box laterally, moving it out of the bottom of the moving vehicle. Then, as the pruning robotic arm starts, it prunes the branches and leaves. The fallen branches and leaves slide along the first inclined surface to the second inclined surface. Under the action of the second inclined surface, they move towards the end of the collection trough away from the first inclined surface, thus preventing the branches and leaves from accumulating at the first inclined surface. At the same time, the vertical plates around the collection box prevent the wind from blowing away the pruned branches and leaves. After pruning is complete, the drive rod can be controlled to move the collection box to the bottom of the moving vehicle, thus shielding the top of the collection box and reducing the occurrence of pruned branches and leaves falling.

[0008] Preferably, to facilitate the storage of pruned branches and leaves in the collection trough: the inclination angle of the first inclined surface is 45°-80°, and the inclination angle of the second inclined surface is 3°-10°. The high point of the second inclined surface contacts the low point of the first inclined surface, so that fallen branches and leaves slide from the first inclined surface to the second inclined surface, avoiding the accumulation of branches and leaves at the position of the first inclined surface.

[0009] Preferably, to facilitate the movement of the collection box: the driving assembly includes a driving rod for providing driving force, a linkage plate disposed at the output end of the driving rod for linkage between the output end of the driving rod and the collection box, and a connector disposed between the linkage plate and the collection box for connecting the linkage plate and the collection box. The top end of the driving rod is fixedly connected to the bottom end of the mobile vehicle, and the output end of the driving rod is fixedly connected to the back of the linkage plate. One end of the front of the linkage plate has a mounting groove for mounting the connector. By extending the output end of the driving rod, the linkage plate is driven to move laterally away from the mobile vehicle. The linkage plate, by driving the plug-in block, realizes the lateral reciprocating movement of the collection box.

[0010] Preferably, to maintain a stable connection between the collection box and the linkage plate: the connector includes a plug-in block inserted into the mounting slot and locking blocks symmetrically arranged at the top and bottom of the plug-in block for locking the plug-in block and the linkage plate. Locking holes are respectively provided at the top and bottom of the inner wall of the mounting slot. The locking blocks are inserted into the locking holes, and one side of the plug-in block is fixedly connected to one side of the collection box. The size of the mounting slot corresponds to the size of the plug-in block, and the number of locking holes corresponds to the number of locking blocks. By inserting the locking blocks into the locking holes, the installation of the plug-in block and the linkage plate is completed, realizing the connection between the collection box and the output end of the drive rod.

[0011] Preferably, to maintain the stability of the locking block inserted into the locking hole: the insert block has an internal cavity, and the inner wall of the cavity has an insertion hole for the locking block to pass through. A baffle for restricting the movement of the locking block is fixedly connected to the end of the locking block near the insert block, and an elastic block for pushing the baffle to move is provided on the side of the baffle away from the locking block. By pushing the baffle with the elastic block, the baffle constantly pushes the locking block, keeping the locking block always inserted into the locking hole, thus achieving a stable connection between the insert block and the linkage plate.

[0012] Preferably, to ensure that the collection box does not deviate from its position during movement: the guide component includes a movable rod disposed on the other side of the collection box and a guide block fixedly installed at the bottom of the moving vehicle for guiding the movable rod's movement. The guide block has a guide groove on its side facing the collection box for the movable rod to slide through. By sliding the movable rod through the guide groove of the guide block, it can guide the collection box during movement, preventing the collection box from deviating from its position.

[0013] This application, through the design of a collection component, a drive component, and a guide component, allows for the following process when tree pruning is required: first, the drive rod is controlled, and the extension of the output end of the drive rod causes the collection box to extend out of the moving vehicle. As the pruning robotic arm prunes, the pruned branches and leaves fall into the collection trough for collection. The vertical plates around the collection box prevent the branches and leaves from being blown away by the wind. After collection, the collection box can be separated from the linkage plate by pressing the locking block, allowing for separate cleaning of the collection box. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This embodiment provides a municipal landscaping tree trimming device, such as... Figure 1-5 As shown, the trimming device includes a trimming robotic arm 1 and a moving vehicle 2 disposed at the bottom end of the trimming robotic arm 1 for moving the trimming robotic arm 1.

[0023] To facilitate the collection of pruned branches and leaves: the bottom of the mobile vehicle 2 is provided with a collection component 3 for collecting pruned branches and leaves, one side of the collection component 3 is provided with a drive component 4 for driving the collection component 3 to move, and the other side of the collection component 3 is provided with a guide component 5 for guiding the movement of the collection component 3; the collection component 3 includes a collection box 31, the top of the collection box 31 is provided with a collection groove 32 for collecting branches and leaves, the end of the collection groove 32 away from the mobile vehicle 2 is a first inclined surface, and the bottom of the inner wall of the collection groove 32 is a second inclined surface. Before the pruning robot arm 1 begins pruning, the drive rod 41 is controlled to move the collection box 31 laterally, moving it out of the bottom of the moving vehicle 2. Then, as the pruning robot arm 1 starts, it prunes the branches and leaves. The fallen branches and leaves slide from the first inclined surface to the second inclined surface. Under the action of the second inclined surface, they move towards the end of the collection trough 32 away from the first inclined surface, thus preventing the branches and leaves from accumulating at the first inclined surface. At the same time, the vertical plates around the collection box 31 prevent the wind from blowing away the pruned branches and leaves. After pruning is completed, the drive rod 41 can be controlled to move the collection box 31 to the bottom of the moving vehicle 2, thus shielding the top of the collection box 31 and reducing the occurrence of pruned branches and leaves falling.

[0024] Furthermore, the mobile vehicle 2 and the pruning robotic arm 1 constitute a conventionally used branch and leaf pruning vehicle. The mobile vehicle 2 supplies power to the pruning robotic arm 1 and drives and controls the pruning robotic arm 1 to extend outward to prune the branches and leaves of trees. The pruning robotic arm 1 can be a commonly used branch and leaf pruning robotic arm, which generally includes a main arm that can rotate around a base and can extend and retract back and forth. A rotatable pruning base is provided at the end of the main arm, and pruning shears are installed on the pruning base. The branches and leaves can be pruned by driving the pruning shears to move quickly.

[0025] Specifically, to facilitate the storage of pruned branches and leaves in the storage trough 32: the inclination angle of the first inclined surface is 45°-80°, and the inclination angle of the second inclined surface is 3°-10°. The high point of the second inclined surface contacts the low point of the first inclined surface, so that fallen branches and leaves slide from the first inclined surface to the second inclined surface, preventing branches and leaves from accumulating at the first inclined surface. The inclination angle of the first inclined surface is 60°, and the angle of the second inclined surface is 6°. The contact area between the first and second inclined surfaces is rounded to facilitate the sliding of branches and leaves. Through the inclination of the second inclined surface, the pruned branches and leaves slide towards the end of the storage trough 32 away from the first inclined surface.

[0026] Specifically, to facilitate the movement of the collection box 31, the drive assembly 4 includes a drive rod 41 for providing driving force, a linkage plate 42 disposed at the output end of the drive rod 41 for linkage between the output end of the drive rod 41 and the collection box 31, and a connector disposed between the linkage plate 42 and the collection box 31 for connecting the linkage plate 42 and the collection box 31. The top end of the drive rod 41 is fixedly connected to the bottom end of the mobile vehicle 2, and the output end of the drive rod 41 is fixedly connected to the back of the linkage plate 42. One end of the front of the linkage plate 42 has a mounting groove for mounting the connector. By extending the output end of the drive rod 41, the linkage plate 42 is driven to move laterally away from the mobile vehicle 2. The linkage plate 42 drives the plug-in block 43, thereby driving the collection box 31 to move laterally back and forth. The drive rod 41 is an existing electrically controlled multi-stage hydraulic telescopic rod. The drive rod 41 is electrically connected to the mobile vehicle 2. The start and stop of the drive rod 41 are controlled by the mobile vehicle 2. When it is necessary to collect pruned branches and leaves, the output end of the drive rod 41 is extended. The part of the drive rod 41 that contacts the linkage plate 42 is fixed with bolts. The output end of the drive rod 41 drives the linkage plate 42 to move synchronously. The linkage plate 42 drives the connecting parts to move synchronously. The connecting parts drive the collection box 31 to move synchronously, so that the collection box 31 extends to collect branches and leaves. When it is necessary to retract the collection box 31, the output end of the drive rod 41 is retracted to move the collection box 31 to the bottom of the mobile vehicle 2.

[0027] More specifically, to maintain the stability of the connection between the collection box 31 and the linkage plate 42, the connector includes a plug-in block 43 inserted into the mounting groove and locking blocks 44 symmetrically arranged at the top and bottom of the plug-in block 43 for locking the plug-in block 43 and the linkage plate 42. Locking holes are respectively provided at the top and bottom of the inner wall of the mounting groove. The locking blocks 44 are inserted into the locking holes, and one side of the plug-in block 43 is fixedly connected to one side of the collection box 31. The size of the mounting groove corresponds to the size of the plug-in block 43, and the number of locking holes corresponds to the number of locking blocks 44. By inserting the locking blocks 44 into the locking holes, the installation of the plug-in block 43 and the linkage plate 42 is completed, realizing the connection between the collection box 31 and the output end of the drive rod 41. The parts of the plug-in block 43 that contact the collection box 31 are welded and fixed, and the size of the mounting groove is adapted to the size of the plug-in block 43.

[0028] To ensure the stability of the locking block 44 within the locking hole, the insert block 43 has an internal cavity with an insertion hole for the locking block 44. A baffle 45 is fixedly connected to the end of the locking block 44 near the insert block 43 to restrict its movement. An elastic block 46 is provided on the side of the baffle 45 away from the locking block 44 to push it. The elastic block 46 pushes the baffle 45, ensuring it constantly pushes the locking block 44, thus maintaining its position within the locking hole and ensuring a stable connection between the insert block 43 and the linkage plate 42. The size of the insertion hole is the same as that of the locking hole, and both are adapted to the size of the locking block 44. The size of the baffle 45 is 1.2 times the size of the insertion hole. Both the baffle 45 and the elastic block 46 are set in the cavity. The elastic block 46 is an elastic rubber block. The elastic block 46 is always in a compressed state in the cavity. The contact parts of the baffle 45 and the locking block 44 are welded and fixed. The two ends of the elastic block 46 are respectively bonded to the contact parts of the baffle 45 and the inner wall of the cavity. At the same time, by pressing the locking block 44, the collection box 31 can be disassembled to collect and clean the branches and leaves.

[0029] Specifically, to ensure that the collection box 31 does not deviate from its position during movement, the guide component 5 includes a movable rod 51 located on the other side of the collection box 31 and a guide block 52 fixedly installed at the bottom of the moving vehicle 2 for guiding the movement of the movable rod 51. The guide block 52 has a guide groove on the side facing the collection box 31 for the movable rod 51 to slide through. By sliding the movable rod 51 through the guide groove of the guide block 52, it can guide the collection box 31 during movement, preventing the collection box 31 from deviating. The size of the guide groove is adapted to the size of the movable rod 51. The top of the guide block 52 is welded and fixed to the bottom of the moving vehicle 2, and the part of the movable rod 51 that contacts the collection box 31 is welded and fixed. The guide groove is a horizontal straight groove. When the collection box 31 is moved laterally by the drive rod 41, the movable rod 51 slides in the guide groove, thereby maintaining the stability of the lateral movement of the collection box 31 and preventing deviation.
