Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of property management greening maintenance equipment, and in particular relates to a greening repair shear for property management. Background Technology
[0002] In the greening maintenance work of property management, tree pruning is a frequent and important task. Its purpose is to ensure the aesthetic appearance of trees, promote their healthy growth, and prevent overly dense or tall branches from obstructing pedestrian traffic, blocking public facilities (such as streetlights and surveillance cameras), or posing a risk of falling over. Currently, the greening trimmers commonly used in property management are mostly traditional manual trimmers. Their core structure is based on the lever principle and mainly consists of a fixed clamping arm, a movable clamping arm, and a handle. Manually pressing the handle drives the movable clamping arm to rotate around the hinge point, thus cutting the branches.
[0003] However, traditional manual landscaping trimmers have some shortcomings in practical use, especially when dealing with thicker branches. Cutting them is difficult, time-consuming, and labor-intensive. The lever ratio of traditional trimmers is limited, resulting in relatively low cutting force when the handle is manually pressed. For thicker branches, operators need to exert considerable force to close the clamps, and each cut often requires continuous force, which may lead to interruption due to insufficient force, significantly reducing work efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide greening repair shears for property management, aiming to solve the technical problem that the existing technology may have interrupted shearing due to insufficient force, which greatly reduces the efficiency of operation.
[0005] To achieve the above objectives, the utility model provides a property management greening repair shear, which includes a fixing mechanism, a support base, a hydraulic shearing mechanism, and an anti-slip mechanism. The support base is disposed on the fixing mechanism, and the hydraulic shearing mechanism is movably disposed on the support base. The anti-slip mechanism is disposed on the hydraulic shearing mechanism.
[0006] The hydraulic shear mechanism includes a left hydraulic shear assembly and a right hydraulic shear assembly. The left hydraulic shear assembly is movably disposed on one side of the support base, and the right hydraulic shear assembly is movably disposed on the other side of the support base.
[0007] The left hydraulic shear assembly includes a left hydraulic cylinder, a left clamp arm, and a left arm pivot. The left hydraulic cylinder is rotatably connected to the support base and the left clamp arm, and is used to drive the left clamp arm to rotate along the left arm pivot. The left clamp arm is fixed to the left arm pivot and is located on one side of the right hydraulic shear assembly. The left arm pivot is movably inserted through the support base. A receiving groove is provided in the middle of the left clamp arm.
[0008] The right hydraulic shear assembly includes a right hydraulic cylinder, a right clamp arm, and a right arm pivot. The right hydraulic cylinder is rotatably connected to the support base and the right clamp arm. The right hydraulic cylinder drives the right clamp arm to rotate along the right arm pivot and can drive the right clamp arm to be accommodated in the receiving groove. The right clamp arm is fixed to the right arm pivot and is located on one side of the left hydraulic shear assembly. The right arm pivot is movably inserted through the support base.
[0009] The anti-slip mechanism includes an anti-slip protrusion and an anti-slip ring. The anti-slip protrusion and the anti-slip ring are respectively disposed on the left clamp arm and the right clamp arm. The anti-slip protrusion is fixed to the left clamp arm and the right clamp arm respectively, and the anti-slip ring is fixed to the anti-slip protrusion.
[0010] As an optional embodiment of this invention, the receiving groove is arranged to coincide with the right clamp arm.
[0011] As an optional solution of this utility model, a left limiting block is provided at one end of the left clamp arm. There are two left limiting blocks, which are arranged in parallel and spaced apart. The left limiting blocks are fixedly connected to the left clamp arm in an inclined shape. Multiple anti-slip protrusions and anti-slip rings are provided and are all provided on the left limiting blocks. The multiple anti-slip protrusions are all fixed to the left limiting blocks.
[0012] As an optional solution of this utility model, a left wear-resistant plate is provided on one side of the left clamp arm, and multiple left wear-resistant plates are provided, all of which are fixedly connected to the left clamp arm.
[0013] As an optional solution of this utility model, a right limiting block is provided at one end of the right clamp arm, and the right limiting block is fixedly connected to the right clamp arm in an inclined shape; multiple anti-slip protrusions and anti-slip rings are provided, and all are provided on the right limiting block, and multiple anti-slip protrusions are fixed to the right limiting block.
[0014] As an optional solution of this utility model, a right wear-resistant plate is provided on one side of the right clamp arm, and multiple right wear-resistant plates are provided, all of which are fixedly connected to the right clamp arm.
[0015] As an optional solution of this utility model, the fixing mechanism includes a fixing plate, a fixing disk, a limiting disk, and a limiting bolt. The fixing plate is fixedly connected to the fixing disk, and the fixing plate is provided with a fixing hole. The limiting disk is disposed on the fixing disk, and the limiting bolt is threadedly connected to the limiting disk and the fixing disk in sequence. The support base is fixedly connected to the limiting disk.
[0016] The above-mentioned technical solutions of one or more of the greening trimmers for property management provided in this utility model embodiment have at least one of the following technical effects:
[0017] The landscaping trimmers provided in this application use a hydraulic shearing mechanism instead of the traditional manual lever structure.

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0036] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0037] In one embodiment of this utility model, such as Figures 1-5 As shown, a greening repair shear is provided for property management, comprising a fixing mechanism 1, a support base 2, a hydraulic shearing mechanism, and an anti-slip mechanism 5. The support base 2 is fixedly installed on the fixing mechanism 1, and the hydraulic shearing mechanism is movably mounted on the support base 2 via a rotating shaft, allowing for flexible rotation.
[0038] The hydraulic shear mechanism includes a left hydraulic shear assembly 3 and a right hydraulic shear assembly 4, which are symmetrically distributed and movably mounted on both sides of the support base 2. An anti-slip mechanism 5 is installed within the hydraulic shear mechanism.
[0039] The left hydraulic shear assembly 3 mainly consists of a left hydraulic cylinder 31, a left clamp arm 32, and a left arm rotating shaft 33. The cylinder body of the left hydraulic cylinder 31 is rotatably connected to the left ear plate of the support base 2 via a pin, and its piston rod is rotatably connected to one end of the left clamp arm 32 via a pin. The bottom of the left clamp arm 32 is fixedly sleeved on the left arm rotating shaft 33, which is movably inserted into the support base 2 via bearings. When the left hydraulic cylinder 31 extends or retracts, it drives the left clamp arm 32 to rotate around the left arm rotating shaft 33. A receiving groove 321 is provided along the length of the left clamp arm 32 in the middle. The shape and size of this receiving groove 321 match those of the right clamp arm 42, and it is used to accommodate the right clamp arm 42 when the shearing is closed.
[0040] The right hydraulic shear assembly 4 is structurally similar to the left hydraulic shear assembly 3, including a right hydraulic cylinder 41, a right clamping arm 42, and a right arm pivot 43. The cylinder body of the right hydraulic cylinder 41 is rotatably connected to the right ear plate of the support base 2 via a pin, and its piston rod is rotatably connected to one end of the right clamping arm 42 via a pin. The middle part of the right clamping arm 42 is fixedly sleeved on the right arm pivot 43, which is movably inserted into the support base 2 via bearings. When the right hydraulic cylinder 41 extends or retracts, it drives the right clamping arm 42 to rotate around the right arm pivot 43. During shearing operations, the right hydraulic cylinder 41 can drive the right clamping arm 42 to precisely enter the receiving groove 321 of the left clamping arm 32, achieving interference-free closure.
[0041] The anti-slip mechanism 5 includes an anti-slip protrusion 51 and an anti-slip ring 52. The anti-slip protrusion 51 and the anti-slip ring 52 are respectively disposed on the left clamp arm 32 and the right clamp arm 42. The anti-slip protrusion 51 is fixed to the left clamp arm 32 and the right clamp arm 42, and the anti-slip ring 52 is fixed to the anti-slip protrusion 51. During the pruning of branches, the anti-slip protrusion 51 and the anti-slip ring 52 have a limiting function to prevent the branches from slipping out.
[0042] To optimize the shearing effect, two left limiting blocks 322 are fixedly installed at the shearing end of the left clamp arm 32. The two left limiting blocks 322 are parallel and spaced apart, forming a limiting space. The left limiting blocks 322 are welded to the left clamp arm 32 at an inclined angle, which matches the force direction during material shearing, effectively preventing material slippage during the shearing process. Simultaneously, multiple left wear-resistant plates 323 are bolted to the side of the left clamp arm 32 that contacts the material. The left wear-resistant plates 323 are made of high-strength alloy material, which improves the wear resistance of the left clamp arm 32. Multiple anti-slip protrusions 51 and anti-slip rings 52 are provided and are all located on the left limiting blocks 322, with the multiple anti-slip protrusions 51 fixed to the left limiting blocks 322.
[0043] Correspondingly, a right limiting block 421 is fixedly installed at the shearing end of the right clamp arm 42. The right limiting block 421 is welded to the right clamp arm 42 at an inclined angle, which matches the left limiting block 322 to jointly achieve the function of limiting the material. On the side of the right clamp arm 42 that contacts the material, multiple right wear-resistant plates 422 are also fixedly installed by bolts. The right wear-resistant plates 422 are made of the same high-strength alloy material as the left wear-resistant plate 323 to improve the wear resistance of the right clamp arm 42. Multiple anti-slip protrusions 51 and anti-slip rings 52 are provided and are all located on the right limiting block 421. All the anti-slip protrusions 51 are fixed to the right limiting block 421.
[0044] The fixing mechanism 1 includes a fixing plate 11, a fixing disk 12, a limiting disk 13, and limiting bolts 14. One end of the fixing plate 11 is welded to the edge of the fixing disk 12. The fixing plate 11 has fixing holes 111 for securing the entire property management landscaping repair shears to the operating equipment or support using bolts. The limiting disk 13 is positioned above the fixing disk 12, and the two are connected and fixed by multiple limiting bolts 14. The limiting bolts 14 pass through the threaded holes of the limiting disk 13 and the fixing disk 12 in sequence and are tightened. By adjusting the tightness of the limiting bolts 14, the angle of the limiting disk 13 can be finely adjusted, thereby adjusting the operating angle of the entire hydraulic shear mechanism. The bottom of the support base 2 is fixedly connected to the upper surface of the limiting disk 13 by bolts.
[0045] The working process of this utility model is as follows:
[0046] Equipment fixing and angle adjustment:
[0047] Fix the fixing plate 11 of the fixing mechanism 1 to the adjustable height greening maintenance bracket with bolts, and adjust the height of the bracket to the branch pruning position;
[0048] Loosen the limit bolt 14, rotate the limit plate 13 until the cutting direction of the hydraulic shear mechanism is consistent with the direction of the tree branch (i.e., the openings of the left clamp arm 32 and the right clamp arm 42 are facing the tree branch), then pass the limit bolt 14 through the corresponding limit hole and tighten it to fix the limit plate 13.
[0049] Tree branch positioning:
[0050] The operator uses a handheld auxiliary rod to push the thick branch to be cut between the left clamp arm 32 and the right clamp arm 42, so that the branch fits against the inner sidewalls of the left limit block 322 and the right limit block 421, ensuring that the cutting position of the branch is located at the cutting edge of the left clamp arm 32 and the right clamp arm 42; at this time, the anti-slip protrusion 51 and the anti-slip ring 52 are in close contact with the surface of the branch, initially achieving anti-slip positioning.
[0051] Start the hydraulic system and execute the shearing operation:
[0052] Start the external hydraulic pump station and control the hydraulic pump station to supply oil to the left hydraulic cylinder 31 and the right hydraulic cylinder 41, so that the piston rods of the two cylinders extend synchronously.
[0053] The piston rod of the left hydraulic cylinder 31 pushes the left clamp arm 32 to rotate clockwise around the left arm pivot 33, and the piston rod of the right hydraulic cylinder 41 pushes the right clamp arm 42 to rotate counterclockwise around the right arm pivot 43. The cutting edges of the left clamp arm 32 and the right clamp arm 42 gradually close, applying a shearing force to the tree branch.
[0054] As the piston rod continues to extend, the shearing end of the right clamp arm 42 gradually embeds into the receiving groove 321 of the left clamp arm 32, and the shearing force continues to increase until the branch is completely cut off. During this process, the anti-slip protrusion 51 and the anti-slip ring 52 effectively prevent the branch from sliding, the left limit block 322 and the right limit block 421 prevent the branch from falling off, and the left wear-resistant plate 323 and the right wear-resistant plate 422 withstand frictional impact.
[0055] Reset and next operation:
[0056] After the tree branch is cut, the hydraulic pump station is controlled to supply oil in reverse, so that the piston rods of the left hydraulic cylinder 31 and the right hydraulic cylinder 41 retract synchronously, and the left clamp arm 32 and the right clamp arm 42 rotate in opposite directions, opening the opening.
[0057] Use the assist rod to remove the cut branch, and then repeat the steps to cut the next thick branch.
[0058] The greening repair shears for property management provided in this application adopt a hydraulic shearing mechanism instead of the traditional manual lever structure. The left hydraulic cylinder 31 of the left hydraulic shear assembly 3 and the right hydraulic cylinder 41 of the right hydraulic shear assembly 4 drive the left clamp arm 32 and the right clamp arm 42 to rotate, respectively. The hydraulic drive can provide a large shearing force (the maximum shearing force can reach 5-8kN), which can easily cut relatively thick branches and improve the shearing efficiency.
[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
