Description

Technical Field

[0001] The present invention relates to a hedge trimmer. Background Art

[0002] Hedge trimming is carried out by a person using a hedge trimmer or an electric hedge trimmer. The disadvantage of this is that it may be laborious because the tool may be cumbersome or have to be held high. For very tall hedges, a curtain staircase or a similar device is usually used. However, this kind of work has the risk of accidents, such as falling or getting injured when operating the equipment.

[0003] Through the present invention, the applicant has invented a simple and effective tool for cutting / trimming hedges. The present invention is particularly suitable for trimming tall hedges. This is achieved by a rear trimmer, which includes: a longitudinally extending track connected to support legs fixed to the ground; a control unit designed to move along the track; and a cutting tool provided on the control unit and used for shearing or trimming the top of the hedge.

[0004] The track can achieve smooth trimming, making the hedge look neater.

[0005] In one aspect of the present invention, extendable arms are arranged on the track to adapt to the width of the hedge.

[0006] In another aspect of the present invention, additional arms extending downward along both sides of the hedge from the first arm are also provided, and cutting tools for shearing both sides of the hedge are mounted on these arms. Brief Description of the Drawings

[0007] The present invention will be described below with reference to the drawings, where: Figure 1 The device is shown in an upper perspective view; Figure 2 The device is shown in a lower perspective view; and Figure 4 shows the cutting part.

[0008] Brief Introduction of the Illustrations The track 3 is arranged longitudinally along the hedge. It is along the middle direction of the hedge, and its position is preferably slightly lower than the top of the hedge. Preferably, it is located about 10 cm below the ideal height of the hedge or the highest point of the hedge. The two support legs 1 and 2 support both ends 3 of the track (i.e., both ends of the hedge) and are set to be fixed to the ground.

[0009] If the hedge is long, additional support feet can also be provided.

[0010] A steering and motor unit 4 is provided on the track 3 ( Figure 2). This unit includes a lower part 6 ( Figure 3 ), which is designed to cooperate with the track 3 so that the unit can move along the track 3 in a controlled manner. In one embodiment, the device includes a motor (not shown) for moving the device. The motor can rotate one or more wheels to make the wheels run along the track 3. Alternatively, a rack and pinion system can also be used. However, those skilled in the art can understand that there are various ways to achieve this function.

[0011] The device 9 ( Figure 2 ) is used to remove debris that may be deposited on the track during construction. For example, a fan, a brush, or a milling mechanism can be used, so that small branches and the like that may grow into the track can be removed.

[0012] In the unit 4, the operating functions of the hedge trimmer are provided, such as power supply. The power supply can be a battery. Alternatively, the guide rail 3 can be energized and connected to the mains.

[0013] A computer unit for controlling the hedge trimmer can be built into the unit 4.

[0014] The unit 4 includes a cross beam 5 perpendicular to the track 3. A cutting device 20 is installed at the bottom of the cross beam 5. In one embodiment, the cutter can move relative to the cross beam 5, so it can be used for hedges of different widths. Additionally, interchangeable lawn mowers can also be used and selected according to the width of the hedge.

[0015] The cross beam 5 is hollow and has two arms 7 and 8, which can move inside and outside the cross beam 5. That is to say, the arms can extend to adapt the width of the device to the width of the hedge. In this way, the device can be used for hedges of different widths.

[0016] Vertical arms 10 and 11 extending towards the ground are respectively installed at both ends of the arms 7 and 8. The length of this arm is preferably adjustable so as to be used for hedges of different heights.

[0017] Additional cutting devices 21 and 22 are also installed on the arms. These cutters can move up and down along the arms 10 and 11 respectively for trimming both sides of the hedge.

[0018] In another embodiment, the arms (7, 8) can also move forward to trim the ends of the hedge.

[0019] Within the scope of the present invention, several modifications can also be made. For example, it can include a device for remotely controlling the lawn mower. If necessary, autonomous operation can also be achieved by using a data unit.
