Description

Technical Field

[0001] This utility model relates to the field of tree trimmers, and in particular to a multi-angle, wide-range tree trimmer. Background Technology

[0002] A tree trimmer is a mechanical device used to prune tree branches. It is typically equipped with a saw blade or shears, enabling efficient branch cutting. It is widely used in landscaping, orchard management, and forest maintenance. A common structure uses a toothed fixed blade as a base, with a linearly moving movable blade. The linear movement of the movable blade is controlled by a rotary drive (electric or internal combustion engine), thus creating a shearing force between the movable and fixed blades.

[0003] Currently, tree pruning machines are generally linear in shape, limiting them to specific designs, such as the shape of a "Π". Therefore, they are not very adaptable to different landscaping designs and cannot efficiently complete the pruning process. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-angle, wide-range tree pruning machine, which aims to solve the problem that current tree pruning machines are generally linear or limited to specific shapes, have weak adaptability to different greening shapes, and cannot efficiently complete the pruning process.

[0005] To achieve the above objectives, this utility model provides a multi-angle, wide-range tree trimming machine, comprising: The device comprises three trimming functional units, each including a structural groove plate, fixed blade teeth, movable blade teeth, and a rotation drive. The structural groove plate has a U-shaped cross-section with an open lower section. A connecting seat is provided on the upper part of the structural groove plate, and multiple fixing holes are spaced apart along its length. The fixed blade teeth are fixed to the structural groove plate and located at the open section. The movable blade teeth are slidably disposed on the structural groove plate along its length and are fitted with the fixed blade teeth in the thickness direction. The rotation drive is mounted on the structural groove plate and outputs an eccentric wheel. The rotation drive drives the movable blade teeth to reciprocate along the length of the structural groove plate via a connecting rod. Multiple fixing bolt assemblies, each comprising bolts and nuts that are detachably connected to each other, wherein the bolts sequentially pass through the fixing holes on two of the structural slot plates and are connected to the nuts to form a fixation; The connecting arm forms a detachable connection with the connecting seat; The angle between two adjacent trimming functional parts is adjusted and then locked by the fixing bolt assembly.

[0006] Furthermore, the cross-section of the fixing hole is square, and the cross-section of the bolt corresponding to the fixing hole portion is also square.

[0007] Furthermore, the length of the connecting arm is adjustable.

[0008] Furthermore, the connecting arm is of the electrically telescopic type.

[0009] Furthermore, the connecting seat includes a flange, and the connecting arm forms a flange connection with the flange.

[0010] Furthermore, the flange is parallel to the height direction of the structural groove plate.

[0011] Furthermore, the number of connecting arms is three, and each arm is provided corresponding to one of the three structural slot plates.

[0012] Furthermore, the structural groove plate is made of stainless steel.

[0013] Furthermore, the multi-angle wide-range tree trimmer also includes a connecting plate that connects the tops of the two structural slot plates at both ends.

[0014] Furthermore, the multi-angle wide-range tree trimmer also includes a transfer vehicle, to which the free end of the connecting arm is connected.

[0015] This utility model provides a multi-angle, wide-range tree trimming machine. Multiple fixing holes are spaced apart along the length of the upper part of the structural trough plate. The angle between two adjacent trimming functional sections is adjusted and then locked by a fixing bolt assembly. Adjacent structural trough plates are overlapped in the thickness direction to avoid mutual interference between operations. Different structural shapes can be formed by adjusting the angle of two adjacent trimming functional sections. If the three trimming functional sections are linear, the trimming range can be increased. Different total length adjustments can be achieved by adjusting the overlap between adjacent trimming functional sections. If the three trimming functional sections are non-linearly angled, different landscaping shapes can be matched and trimmed in one operation. Similarly, the shape can be diversified by adjusting the overlap between adjacent trimming functional sections. Attached Figure Description

[0020] Reference Figures 1 to 6 In one embodiment of this utility model, a multi-angle, wide-range tree trimming machine includes: Three trimming function units 100 are provided. Each trimming function unit 100 includes a structural groove plate 110, a fixed blade tooth 120, a movable blade tooth 130, and a rotation drive 140. The cross-section of the structural groove plate 110 is U-shaped with an open opening 111 at the bottom. A connecting seat 150 is provided on the upper part of the structural groove plate 110, and multiple fixing holes 112 are provided at intervals along its length. The fixed blade tooth 120 is fixed to the structural groove plate 110 and located at the open opening 111. The movable blade tooth 130 is slidably disposed on the structural groove plate 110 along its length direction. The movable blade tooth 130 and the fixed blade tooth 120 are fitted together in the thickness direction. The rotation drive 140 is mounted on the structural groove plate 110 and outputs an eccentric wheel. The rotation drive 140 drives the movable blade tooth 130 to reciprocate along the length direction of the structural groove plate 110 through a connecting rod. Multiple fixing bolt assemblies 200, each fixing bolt assembly 200 including bolts and nuts that are detachably connected to each other, wherein the bolts sequentially pass through the fixing holes 112 on two of the structural slot plates 110 and are connected to the nuts to form a fixation; The connecting arm 300 is detachably connected to the connecting seat 150; The angle between two adjacent trimming function parts 100 is adjusted and then locked by the fixing bolt assembly 200.

[0021] In existing technologies, tree pruning machines are generally linear and limited to specific shapes, such as the shape of a "Π". Therefore, they are not very adaptable to different landscaping shapes and cannot efficiently complete the pruning process.

[0022] The multi-angle wide-range tree trimmer provided by this utility model includes three trimming function parts 100, multiple fixing bolt assemblies 200 and connecting arms 300.

[0023] The main structure consists of three trimming functional units 100. Each trimming functional unit 100 includes a structural slot plate 110, fixed blade teeth 120, movable blade teeth 130, a rotation drive 140, and connecting rods. The structural slot plate 110 has a U-shaped cross-section with an open opening 111 at the bottom, thus forming a working space within the structural slot plate 110. A connecting seat 150 is provided on the upper part of the structural slot plate 110. The direction from the open opening 111 to the connecting seat 150 is the height direction. The directions of the two side walls of the structural slot plate 110 are the thickness direction. Multiple fixing holes 112 are provided at intervals along the length of the upper part of the structural slot plate 110. The fixed blade teeth 120 are fixed to the structural slot plate 110 and located at the open opening 111, while the movable blade teeth 130 are slidably disposed on the structural slot plate 110 along its length. For example, sealing plates are provided at both ends of the structural slot plate 110 along its length, and mounting holes are provided on the sealing plates, through which the movable blade teeth 130 pass. The movable blade tooth 130 and the fixed blade tooth 120 are fitted together in the thickness direction. A rotary drive 140 is mounted on the structural slot plate 110 and outputs an eccentric wheel. A connecting rod connects the eccentric wheel and the movable blade tooth 130. The rotary drive 140 drives the movable blade tooth 130 to reciprocate along the length of the structural slot plate 110. The rotary drive 140 can be an electric motor or an internal combustion engine.

[0024] Multiple fixing bolt assemblies 200 are used to secure the three trimming functional parts 100. Each fixing bolt assembly 200 includes bolts and nuts that are detachably connected to each other. The bolts are sequentially connected to the nuts through fixing holes 112 on two structural slot plates 110 to form a fixation. Adjacent structural slot plates 110 are overlapped in the thickness direction to avoid mutual interference between operations.

[0025] The connecting arm 300 and the connecting seat 150 form a detachable connection, so that the connecting arm 300 can support the whole formed by the three trimming functional parts 100.

[0026] After the angle between two adjacent trimming functional sections 100 is adjusted, they are locked together by the fixing bolt assembly 200. By adjusting the angle between two adjacent trimming functional sections 100, different structural shapes can be formed. For example, if the three trimming functional sections 100 are in a linear arrangement, the trimming range can be increased; if the three trimming functional sections 100 are in a "Π" shape, the trimming action can be completed in one go. Since multiple fixing holes 112 are provided at intervals on the upper part of the structural groove plate 110, different shape dimensions can be formed by adjusting the overlap between two adjacent trimming functional sections 100.

[0027] In summary, the upper part of the structural trough plate 110 is provided with multiple fixing holes 112 at intervals along its length. After the angle between two adjacent pruning functional parts 100 is adjusted, they are locked by fixing bolt assembly 200. The adjacent structural trough plates 110 are stacked in the thickness direction to avoid mutual interference between operations. Different structural shapes can be formed by adjusting the angle of two adjacent pruning functional parts 100. If the three pruning functional parts 100 are linear, the pruning range can be increased. Different total length adjustments can be achieved by adjusting the overlap between adjacent pruning functional parts 100. If the three pruning functional parts 100 are non-linearly angled, different greening shapes can be matched to complete the pruning action in one go. Similarly, the shape can be diversified by adjusting the overlap between adjacent pruning functional parts 100.

[0028] In one embodiment, the cross-section of the fixing hole 112 is square, and the cross-section of the bolt corresponding to the portion of the fixing hole 112 is also square.

[0029] In this embodiment, by limiting the cross-section, the possibility of abnormal rotation after two adjacent structural slot plates 110 are fixed is eliminated.

[0030] In one embodiment, the length of the connecting arm 300 is adjustable.

[0031] In this embodiment, the working position of the tree trimmer can be adjusted to multiple angles and a wide range by adjusting the length of the connecting arm 300. The length adjustment method of the connecting arm 300 can be varied. For example, the connecting arm 300 may include multiple threaded sub-rods, with the length adjusted by changing the degree of thread engagement; or the connecting arm 300 may include two sub-rods, the degree of engagement between the two sub-rods can be changed, and locking is achieved through a bolt structure; or the connecting arm 300 may be an electrically or hydraulically driven telescopic rod.

[0032] In one embodiment, the connecting arm 300 is electrically telescopic.

[0033] In this embodiment, the connecting arm 300 is limited to an electrically telescopic type, thereby avoiding the introduction of a hydraulic station.

[0034] Reference Figures 1 to 4 In one embodiment, the connecting seat 150 includes a flange, and the connecting arm 300 forms a flange connection with the flange.

[0035] In this embodiment, the connecting arm 300 and the connecting seat 150 are configured as a flange connection, so that the installation angle between the connecting arm 300 and the connecting seat 150 can be adjusted during the installation process. The angle between the structural slot plate 110 and the connecting arm 300 can be adjusted accordingly. The lower part of the structural slot plate 110 has an open opening 111, while the upper part has a connecting seat 150. The direction from the open opening 111 to the connecting seat 150 is the height direction. If the flange is perpendicular to the height direction of the structural slot plate 110, the fixed angle of the structural slot plate 110 can be adjusted by rotation in a plane; if the flange is parallel to the height direction of the structural slot plate 110, the fixed angle of the structural slot plate 110 can be oscillated in a vertical plane.

[0036] Reference Figures 5 to 6 In one embodiment, the flange is parallel to the height direction of the structural groove plate 110.

[0037] In this embodiment, the lower part of the structural groove plate 110 is an open opening 111, while the upper part has a connecting seat 150. The direction from the open opening 111 to the connecting seat 150 is the height direction. Therefore, the fixed angle of the structural groove plate 110 can swing in the vertical plane, making the operating angle of the entire multi-angle wide-range tree trimmer more flexible.

[0038] In one embodiment, the number of connecting arms 300 is three, and each corresponds to one of the three structural slot plates 110.

[0039] In this embodiment, the number of connecting arms 300 is increased and they are respectively connected to the connecting seats 150 of the structural slot plate 110, so that the three connecting arms 300 can serve as a fixed foundation and provide more stable support. The length of the three connecting arms 300 is not limited to be the same, nor is the structural form limited to be the same.

[0040] In one embodiment, the structural groove plate 110 is made of stainless steel.

[0041] In this embodiment, the structural channel plate 110 is limited to stainless steel to provide adequate structural strength and weather resistance. Specifically, the specific type of stainless steel is selected based on the application requirements.

[0042] In one embodiment, the multi-angle wide-range tree trimmer further includes a connecting plate that connects the tops of the two structural slot plates 110 at both ends.

[0043] In this embodiment, the tops of the two structural slot plates 110 at both ends can be connected by the introduction of the connecting plate, thereby improving the structural connection stability between the three structural slot plates 110. The connection method between the connecting plate and the structural slot plate 110 can be varied. For example, the connecting plate is provided with two oblong holes, and the corresponding positions on the structural slot plate 110 are provided with fixing bolts. The connection is achieved by the engagement between the bolts and the oblong holes.

[0044] In one embodiment, the multi-angle wide-range tree trimmer further includes a transfer vehicle to which the free end of the connecting arm 300 is connected.

[0045] In this embodiment, when the three trimming functional units 100 and the connecting arm 300 have a large mass, they can be moved by a transfer vehicle.

[0046] In summary, the multi-angle wide-range tree trimmer provided by this utility model has multiple fixing holes 112 spaced apart on the upper part of the structural groove plate 110 along the length direction. After the angle between two adjacent trimming functional parts 100 is adjusted, they are locked by fixing bolt assembly 200. The adjacent structural groove plates 110 are stacked in the thickness direction to avoid mutual interference between operations. Different structural shapes can be formed by adjusting the angle of two adjacent trimming functional parts 100. If the three trimming functional parts 100 are linear, the trimming range can be increased. Different total length adjustments can be achieved by adjusting the overlap between adjacent trimming functional parts 100. If the three trimming functional parts 100 are non-linearly angled, different greening shapes can be matched to complete the trimming action in one go. Similarly, the shape can be diversified by adjusting the overlap between adjacent trimming functional parts 100.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
