They control the height of shrubs and the thickness of vines by trimming, and shape them to make hedges and green walls an ideal landscape. They can be driven by a gasoline engine, electric motor or hydraulic motor. The working part is the cutting blade. According to its movement mode, it is divided into reciprocating and rotary types.

[0003] Existing garden hedge trimmers are not convenient for workers to arbitrarily adjust the height, angle and position of the cutting blade, thereby increasing the difficulty of trimming green plants in different positions. Therefore, improvements are needed. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a movable garden hedge trimmer.

[0005] The above technical objectives of the present utility model are achieved through the following technical solutions: a movable garden hedge trimmer, comprising a base plate, a universal wheel with a brake system is provided at the bottom of the base plate, four universal wheels are provided and distributed in a rectangular array about the base plate, a mounting frame is provided above the base plate, a trimming assembly for trimming hedges is provided on the mounting frame, an adjustment assembly for adjusting the beveling angle between the trimming assembly and the mounting frame is provided on the mounting frame, a driving assembly for driving the trimming assembly to perform reciprocating motion on the mounting frame is provided on the mounting frame, an electric push rod for driving the mounting frame to rise and fall in the vertical direction is provided on the top of the base plate, and the piston rod end of the electric push rod is fixed to the bottom of the mounting frame.

[0006] By adopting the above technical solution, the staff moves the entire device to the vicinity of the hedge to be trimmed through the universal wheel and adjusts the brake. Then the staff starts the adjustment component to make the trimming component close to the hedge to be trimmed, which is conducive to completing the trimming work of the hedge and performing shaping maintenance, making the hedge or green wall an ideal landscape and improving the ornamental value; the staff starts the electric push rod to drive the mounting frame to drive the trimming component to move in the vertical direction, which is conducive to trimming hedges of different heights and improving the applicability of the trimmer; the staff starts the drive component to drive the trimming component to reciprocate on the mounting frame, which is conducive to trimming the hedges in a certain area and reduces the probability of the staff manually adjusting the universal wheel.

[0007] Furthermore, the trimming assembly includes a mounting rod arranged on a mounting frame, a motor fixed to the top of the mounting rod, and a trimming blade arranged at the end of the output shaft of the motor. The output shaft of the motor passes through the mounting rod and is loosely fitted with the mounting rod.

[0008] By adopting the above technical solution, the staff starts the motor, and after the motor starts working, it drives the pruning blade to rotate at a high height, which is beneficial for pruning the hedge, changing the height of the shrubs or the thickness of the vines, and maintaining their shape, which is beneficial to improving the ornamental value of the hedge or green wall.

[0009] Furthermore, the adjustment assembly includes a mounting plate arranged above the mounting frame, a brake motor fixed on the side wall of the mounting plate, a driving gear fixed to the end of the output shaft of the brake motor, and a driven gear rotatably mounted on one side of the mounting plate and meshing with the driving gear, and the side of the mounting rod away from the trimming blade is fixed to the side of the driven gear.

[0010] By adopting the above technical solution, the staff starts the brake motor, and after the brake motor works, it drives the driving gear to rotate. Since the driving gear is engaged with the driven gear, it drives the mounting rod and the pruning blade to change the inclination angle between the mounting frame, which is conducive to pruning the hedge at different angles and completing the maintenance of the hedge shape.

[0011] Furthermore, the driving assembly includes a driving motor fixed on a side wall of one side of the mounting frame, a threaded rod rotatably installed between the side walls of both sides of the mounting frame, a connecting block sleeved on the threaded rod and threadedly connected to the threaded rod, and a guide rod fixed in the middle of the side walls of both sides of the mounting frame, the threaded rod and the guide rod are arranged parallel to the guide rod, the connecting block is sleeved on the guide rod and slidably cooperates with the guide rod, the bottom of the mounting plate is fixed to the top of the connecting block, and the threaded rod is fixed to the end of the output shaft of the driving motor.

[0012] By adopting the above technical solution, the staff starts the drive motor, and after the drive motor starts working, it drives the threaded rod to rotate. Since one end of the connecting block is threadedly connected to the threaded rod, and the other end is slidingly matched with the guide rod, the circumferential rotation of the connecting block around the threaded rod is limited, so that the connecting block can move horizontally during this process, thereby driving the pruning blade to move synchronously, which is beneficial for the pruning blade to trim the hedges in a certain area, and reduces the probability that the staff needs to adjust the universal wheel and move the bottom multiple times.

[0013] Furthermore, the driven gear is provided with reinforcing ribs, and two reinforcing ribs are provided and are symmetrically arranged about the mounting rod.

[0014] By adopting the above technical solution, the provision of the reinforcing ribs is conducive to improving the connection stability between the mounting rod and the driven gear, thereby helping to improve the stability of the trimming blade during the trimming process.

[0015] Furthermore, a slide rod is provided on the bottom plate, and two slide rods are provided and symmetrically arranged about the mounting frame. Rings are provided on both side walls of the mounting frame that are away from each other. The rings are sleeved on the slide rod and slideably cooperate with the slide rod.

[0016] By adopting the above technical solution, the slide rod and the collar cooperate with each other, which is conducive to improving the movement stability of the mounting frame in the vertical direction.

[0017] Furthermore, an armrest is provided on one side of the base plate, and the armrest is provided with anti-slip grooves.

[0018] By adopting the above technical solution, the setting of the handrail makes it easier for the staff to move the position of the mower with the universal wheels; the setting of the anti-slip groove is conducive to increasing the friction when the staff holds the handrail, reducing the probability of slipping.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. In the present application, the staff moves the entire device to the vicinity of the hedge to be trimmed by means of the universal wheels and adjusts the brakes. The staff then activates the adjustment component to bring the trimming component close to the hedge to be trimmed, which is conducive to completing the trimming work of the hedge and performing shaping maintenance, making the hedge or green wall an ideal landscape and improving the ornamental value; the staff activates the electric push rod to drive the mounting frame to drive the trimming component to move in the vertical direction, which is conducive to trimming hedges of different heights and improving the applicability of the trimmer; the staff activates the drive component to drive the trimming component to reciprocate on the mounting frame, which is conducive to trimming the hedges in a certain area and reduces the probability of the staff manually adjusting the universal wheels;

[0021] 2. In this application, the staff starts the motor, and after the motor works, it drives the pruning blade to rotate at a high speed, which is beneficial for pruning the hedge, changing the height of the shrubs or the thickness of the vines, and maintaining their shape, which is beneficial for improving the ornamental value of the hedge or green wall;

[0022] 3. In this application, the staff starts the brake motor, and after the brake motor works, it drives the driving gear to rotate. Since the driving gear is engaged with the driven gear, it drives the mounting rod and the pruning blade to change the inclination angle with the mounting frame, which is conducive to pruning the hedge at different angles and completing the maintenance of the hedge shape.
