[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0024] See also Figure 1-6A hedge trimmer equipped with a loader includes a mounting base 1, a suspension cover 2 is arranged on the mounting base 1, a side shift cylinder 3 is arranged inside the suspension cover 2, a side shift rod 4 and a hydraulic valve group 5 are arranged on the top of the suspension cover 2, a piston rod of the side shift cylinder 3 is fixedly connected to one end of the side shift rod 4, a swing frame 6 is hingedly arranged on the other end of the side shift rod 4, a swing cylinder 7 is hingedly arranged on the side shift rod 4, the piston rod end of the swing cylinder 7 is hinged to the swing frame 6, and a cutter 8 is arranged on the swing frame 6. Specifically, (1) the rodless chamber of the swing cylinder 7 is supplied with oil, and the rod chamber is returned with oil, and the piston rod is extended, so that the swing frame swings around the side shift rod 4, thereby driving the cutter 8 to swing to the required working position (vertical or horizontal); the rod chamber of the swing cylinder 7 returns oil, the rodless chamber is supplied with oil, and the piston rod is retracted, so that the swing frame swings around the side shift rod 4, thereby driving the cutter 8 to swing to the required working position (horizontal, vertical) or transportation position; (2) the rodless chamber of the side shift cylinder 3 is supplied with oil, and the rod chamber is returned with oil, and the piston rod is extended, so that the side shift rod 4 drives the cutter 8 to move inward, so that the cutter 8 reaches the required working or transportation position; the rod chamber of the side shift cylinder 3 returns oil, the rodless chamber is supplied with oil, the piston rod is retracted, and the side shift rod 4 drives the cutter 8 to move outward, so that the cutter 8 reaches the required working position; the blade of the cutter 8 is made of manganese steel, which has high strength, wear resistance, and stable working performance; the working and transportation positions of the utility model are adjustable, and it can also pass through narrow passages, thereby improving practicality and flexibility.

[0025] In this embodiment, a strip groove 21 is provided on the top of the suspension cover 2, and a rod pin is provided on the piston rod of the side shift oil cylinder 3 to penetrate the strip groove 21 and be fixedly connected to the side shift rod 4. The strip groove 21 plays a certain guiding role to ensure the stability of the side shift rod 4 when it is extended and retracted.

[0026] In this embodiment, a protective cover 9 is disposed outside the hydraulic valve group 5 , and the protective cover 9 protects the hydraulic valve group 5 .

[0027] In this embodiment, a safety latch 10 is provided between the swing frame 6 and the side shift rod 4 (see Figure 4 A transport safety latch 10 is provided, and during transportation, the safety latch locks the swing frame 6 and the side shift rod 4 to prevent safety hazards caused by leakage of the oil cylinder.

[0028] In this embodiment, the cutter 8 is driven by a hydraulic motor. The hydraulic system of the loader is used to provide power to the hydraulic motor, and no additional power is required, which saves costs.

[0029] In this embodiment, the hedge trimmer is remotely controlled by an operating handle (see Figure 6 ). It is remotely controlled by an operating handle, which is simple and convenient to operate.

[0030] The working principle of this utility model:

[0031] Installation and commissioning of the hedge trimmer and loader: First, select a suitable loader and remove its accessories; second, connect the loader suspension device of the hedge trimmer to the mounting base 1; third, connect the hydraulic output port on the loader to the inlet and outlet ports of the hydraulic valve group 5 respectively, then start the loader and operate the handle as shown in the figure:

[0032] (1) Push the operating handle forward: the rodless chamber of the swing oil cylinder 7 is filled with oil, the rod chamber is drained with oil, the piston rod is extended, and the swing frame is swung around the side shift rod 4, thereby driving the cutter 8 to swing to the position where it needs to work (vertical or horizontal); Push the operating handle backward: the rod chamber of the swing oil cylinder 7 is drained with oil, the rodless chamber is filled with oil, the piston rod is retracted, and the swing frame is swung around the side shift rod 4, thereby driving the cutter 8 to swing to the position where it needs to work (horizontal, vertical) or transport;

[0033] (2) Push the operating handle to the left: the rodless chamber of the side shift oil cylinder 3 flows into oil, the rod chamber returns oil, the piston rod extends, and the side shift rod 4 drives the cutter 8 to move inward, so that the cutter 8 reaches the desired working or transporting position; push the operating handle to the right: the rod chamber of the side shift oil cylinder 3 returns oil, the rodless chamber flows oil, the piston rod retracts, and the side shift rod 4 drives the cutter 8 to move outward, so that the cutter 8 reaches the desired working position;

[0034] (3) Press and hold the "Function" button and the "Motor" button at the same time: the hydraulic motor rotates to drive the cutter to work (observe whether the eccentric wheel rotates in the correct direction. When the person faces the loader, the eccentric wheel rotates counterclockwise. If it is not correct, swap the hydraulic output oil pipes).

[0035] The utility model is suitable for supporting use with various types of loaders (matching the connecting parts according to the loader model). When working, the hedge trimmer uses the hydraulic output of the loader, and the operator operates the hedge trimmer according to the operating instructions to rotate the hydraulic motor, thereby driving the cutter 8 to trim the hedge; when transporting and walking, the cutter 8 is folded and tilted inwards (see Figure 4 ), the operating handle is pushed to the left, the piston rod extends to drive the side shift rod and the cutter to move inward to the transport position.

[0036] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
