Description

Technical Field

[0001] The present application belongs to the technical field of hedge trimmers, and in particular to a hedge trimmer. Background Art

[0002] Hedges are the most widely used and planted in garden construction. Their height does not exceed 1.3 meters and their width does not exceed 1 meter. They are mostly planted in double rows with geometric curves. Medium hedges can play the role of separating large scenic areas, organizing tourist activities, increasing green texture, and beautifying the landscape. Medium hedges are mostly built into flower hedges, fruit hedges, and foliage hedges. In order to make the hedges neat and beautiful, they need to be shaped and trimmed regularly to maintain their shape and appearance. Hedge trimmers are usually used to trim the hedges.

[0003] The patent with publication number CN218998938U discloses an electric hedge trimmer, which aims to solve the problem that existing hedge trimmers need manual handheld auxiliary operation, which has high labor intensity for workers; in addition, most of the current hedge trimmers are single-sided trimming, and the trimming efficiency is not high.

[0004] In the above patent, the lifting plate is driven to rise and fall by the push-pull rod of the electric push rod. Although the lifting and falling adjustment function can be completed, the electric push rod, the power source for realizing the adjustment function, is located above the vehicle body, which will limit the retracted height of the lifting platform, thereby affecting the trimming range of the hedge, and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a hedge trimmer that can solve the above problems.

[0006] The purpose of the present application is to provide a hedge trimmer, comprising:

[0007] Mobile base;

[0008] A lifting device is arranged on the mobile base;

[0009] The trimming device is arranged on the lifting device and includes a vertical trimming mechanism and a horizontal trimming mechanism;

[0010] Among them, the lifting device includes a supporting top plate and a supporting bottom plate, an adjustment mechanism arranged between the supporting top plate and the supporting bottom plate, and a driver for driving the adjustment mechanism. The driver is located at the bottom of the mobile base, and the output shaft of the driver passes through the mobile base and the supporting bottom plate and is connected to the adjustment mechanism.

[0011] The above-mentioned hedge trimmer is adopted, by providing a mobile base, the mobile base is used to support other structures, and rollers are installed at the bottom, so that the user can move the trimmer to the place where trimming is required. By providing a lifting device, the trimmer can adjust its working height to adapt to hedges of different heights. The trimmer is installed on the supporting top plate, including a vertical trimming mechanism and a horizontal trimming mechanism. The vertical trimming mechanism is mainly responsible for trimming the vertical surface of the hedge, while the horizontal trimming mechanism is responsible for trimming the top or horizontal surface of the hedge, so as to ensure that its shape meets the design requirements. The coordinated work of the two mechanisms makes the trimming work more efficient.

[0012] At the same time, an adjustment mechanism is provided, which is used to connect the support top plate and the support bottom plate. The position of the support top plate can be changed through the adjustment mechanism, thereby adjusting the height of the pruning device. The driver provides power to the adjustment mechanism so that it can smoothly perform lifting and lowering operations. The driver is located at the bottom of the mobile base, which can not only assist in stabilizing the center of gravity of the entire equipment and reduce the occupied installation space, but also avoid affecting the lifting and lowering of the support top plate. It can also expand the lifting range, increase the pruning range, improve the work efficiency of garden maintenance, and reduce the labor intensity of the operator. In addition, the vertical pruning mechanism is a flippable structure, which can be flipped and stored on the support top plate to facilitate lifting and lowering.

[0013] Furthermore, the regulating mechanism comprises:

[0014] A mounting seat, which is arranged on the supporting base plate and can move on the supporting base plate;

[0015] A support member is symmetrically arranged between the support bottom plate and the support top plate, and two support members are arranged symmetrically on both sides of the mounting seat;

[0016] The vertical plates are symmetrically arranged on both sides of the mounting seat, and each vertical plate is provided with a guide groove;

[0017] A guide connecting rod, both ends of which pass through the guide grooves and are connected to the support member, and the guide connecting rod is connected to the output shaft of the driver;

[0018] Wherein, a through slot for the vertical plate to pass through is arranged on the supporting top plate, and a rotating rod is arranged between the two supporting members.

[0019] When the height needs to be adjusted to trim hedges of different heights, the driver is started. The driver here can be a cylinder or an electric cylinder. The cylinder drives the output shaft to be ejected. Affected by the cylinder output shaft, the guide connecting rod moves up and down along the guide groove. The two ends of the guide connecting rod are connected to the support member. Therefore, as the guide connecting rod moves, the support member will be driven up and down, thereby causing the support top plate to move up and down. At the same time, the mounting seat is arranged on the support bottom plate and can move on the support bottom plate. As the support top plate moves up and down, the mounting seat will slide on the bottom plate with the movement, so that the relative position between the guide connecting rod, the guide groove and the support member remains unchanged. In addition, in the present application, the overall driving mode of the driver is a vertically driven scissors structure, which can further increase the rising and falling height of the support top plate.

[0020] Further: the support member comprises:

[0021] An external connecting rod, one end of which is hinged to the supporting bottom plate and the other end of which is movable on the supporting top plate;

[0022] An inner connecting rod, one end of which is hinged to the supporting top plate and the other end of which is movable on the supporting bottom plate;

[0023] The outer connecting rod and the inner connecting rod are rotatably connected via a rotating rod, and the rotating rod is located in the middle of the outer connecting rod and the inner connecting rod.

[0024] The outer connecting rod and the inner connecting rod are rotatably connected by a rotating rod, and one end of the outer connecting rod is hinged to the supporting bottom plate, and the other end can move on the supporting top plate. One end of the inner connecting rod is hinged to the supporting top plate, and the other end can move on the supporting bottom plate. In this way, when the guide connecting rod moves up and down along the guide groove, it will drive the outer connecting rod and the inner connecting rod to rotate around, thereby completing the lifting and lowering of the trimming device.

[0025] Furthermore, the support member further comprises:

[0026] A first contact wheel is disposed at a non-hinged end of the outer connecting rod, and the first contact wheel is in contact with the supporting top plate;

[0027] A second contact wheel is disposed at the non-hinged end of the inner connecting rod, and the second contact wheel is in contact with the supporting bottom plate;

[0028] The first contact wheel is rotatably connected to the outer connecting rod, and the second contact wheel is rotatably connected to the inner connecting rod.

[0029] By setting a first contact wheel on the end of the outer connecting rod that contacts the support top plate, the wear of the outer connecting rod can be reduced while achieving a supporting effect. By setting a second contact wheel on the end of the inner connecting rod that contacts the support bottom plate, the wear of the inner connecting rod can be reduced while achieving a supporting effect. The coordinated use of the first contact wheel and the second contact wheel can further improve the supporting effect, make the lifting and lowering work smoother, and reduce wear, thereby extending the service life.

[0030] Furthermore, a plurality of rollers are arranged on both sides of the mounting seat, and tracks matching the rollers are arranged on the supporting bottom plate.

[0031] By arranging multiple rollers on both sides of the mounting base and arranging tracks compatible with the rollers on the supporting base plate, the friction force of the mounting base when moving on the supporting base plate can be reduced through the coordinated use of the rollers and the tracks, which facilitates the movement of the mounting base, that is, it can prevent the mounting base from offset when moving, and can also limit the moving distance of the mounting base, so that the overall lifting and lowering work is more stable and the work efficiency is improved.

[0032] Furthermore, the support base plate and the movable base are provided with a first movable groove and a second movable groove in sequence, and the output shaft of the driver passes through the second movable groove, the first movable groove and the mounting plate in sequence and is connected to the guide connecting rod.

[0033] The first movable groove and the second movable groove are sequentially arranged on the supporting base plate and the movable base, and the first movable groove and the second movable groove are used to provide space for the movement of the driver to avoid being stuck during movement.

[0034] The beneficial effects of this application are:

[0035] 1. By using the above-mentioned hedge trimmer and providing a lifting device, the trimmer can adjust its working height to adapt to hedges of different heights;

[0036] 2. The position of the supporting top plate can be changed through the adjustment mechanism, thereby adjusting the height of the pruning device. The driver provides power for the adjustment mechanism, enabling it to smoothly perform lifting and lowering operations. The driver is located at the bottom of the mobile base, which can not only assist in stabilizing the center of gravity of the entire equipment and reduce the installation space occupied, but also avoid affecting the lifting and lowering of the supporting top plate, and can also expand the lifting range, increase the pruning range, improve the work efficiency of garden maintenance, and reduce the labor intensity of the operator;

[0037] 3. By setting a first contact wheel on the end of the outer connecting rod that contacts the support top plate, the wear of the outer connecting rod can be reduced while playing a supporting effect. By setting a second contact wheel on the end of the inner connecting rod that contacts the support bottom plate, the wear of the inner connecting rod can be reduced while playing a supporting effect. The coordinated use of the first contact wheel and the second contact wheel can further improve the supporting effect, make the lifting and lowering work smoother, and reduce wear and tear to extend the service life.

[0057] The mounting base 610 is disposed on the supporting base plate 400 and is movable on the supporting base plate 400;

[0058] The support member 620 is symmetrically arranged between the support bottom plate 400 and the support top plate 300 . Two support members 620 are provided, and the two support members 620 are symmetrically arranged on both sides of the mounting seat 610 .

[0059] The vertical plates 630 are symmetrically arranged on both sides of the mounting base 610, and each vertical plate 630 is provided with a guide groove 631;

[0060] A guide connecting rod 640, both ends of which pass through the guide groove 631 and are connected to the support member 620, and the guide connecting rod 640 is connected to the output shaft of the driver 500;

[0061] The supporting top plate 300 is provided with a through slot 650 for the vertical plate 630 to pass through, and a rotating rod 660 is provided between the two supporting members 620 .

[0062] In the embodiment of the present application, when it is necessary to adjust the height to trim hedges of different heights, the driver 500 is started. The driver 500 here can be a cylinder or an electric cylinder. The cylinder drives the output shaft to be ejected. Under the influence of the cylinder output shaft, the guide connecting rod 640 moves up and down along the guide groove 631.
