Description

Technical Field

[0001] This utility model relates to the field of greening machinery technology, specifically to a hedge trimming device. Background Technology

[0002] A hedge trimming device is a device installed on a locomotive (such as an electric vehicle) to trim hedges. The hedges can be trimmed while the locomotive is in motion.

[0003] The hedge trimming device includes a device body, which includes a mounting base. A trimming arm is mounted on the mounting base, and a trimming shear driven by a trimming motor is mounted on the other end of the trimming arm. The trimming shear includes a first trimming blade and a second trimming blade. Under the action of the trimming motor, the first trimming blade and the second trimming blade continuously engage and disengage, which can trim the hedge vines between the two trimming blades to achieve the trimming effect.

[0004] To improve pruning efficiency, two pruning shears are often installed on the hedge trimming device. For example, these two pruning shears are symmetrically installed on both sides of the other end of the trimming arm.

[0005] In the existing technology, in the hedge trimming device, one trimming motor is connected to one pruning shear, and two pruning shears require two trimming motors. This has the disadvantages of using a large number of trimming motors, increasing the manufacturing cost, and also having a non-compact structure. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned shortcomings by providing a cost-effective and compact hedge trimming device—a hedge trimming device with double trimming shears.

[0007] The technical solution of this utility model is implemented as follows: A hedge trimming device with double trimming shears includes a device body, the device body including a mounting base, on which a trimming arm is mounted, and at the other end of the trimming arm is a trimming shear driven by a trimming motor. The trimming shear includes a first trimming blade and a second trimming blade, the first trimming blade and the second trimming blade respectively having cutting teeth. Two trimming shears are mounted on the hedge trimming device, and these two trimming shears are symmetrically mounted on both sides of the other end of the trimming arm, namely the left trimming shear on the left and the right trimming shear on the right. The trimming motor has an output shaft, the free end of the left trimming shear is set to the left, and the free end of the right trimming shear is set to the right. The feature is that: the trimming motor is a single unit, and a housing is mounted below the trimming motor. The other end of the trimming arm is mounted on the housing. A power gear is installed inside the housing, and the output shaft passes through the housing and is connected to the power gear. Transmission gears and trimming gears are also installed on the left and right sides of the housing respectively. The power gear, transmission gear and trimming gear mesh sequentially, and the trimming gear is connected to the trimming shear extending outside the housing.

[0008] Furthermore, the trimming gear has an upper cylindrical protrusion and a lower cylindrical protrusion, which are collectively referred to as cylindrical protrusions. The upper cylindrical protrusion and the lower cylindrical protrusion are located on the left and right sides of the trimming gear, respectively. The first trimming blade and the second trimming blade are respectively connected to the upper cylindrical protrusion and the lower cylindrical protrusion.

[0009] Furthermore, the trimmer and the cylindrical protrusion are connected by a connector. The trimmer includes a handle near the housing, and the handle has a positioning cylinder. The connector includes a first ring installed on the cylindrical protrusion and a second ring that is engaged with the positioning cylinder of the trimmer. The first ring is fitted around the cylindrical protrusion, and the second ring is fitted around the positioning cylinder.

[0010] The beneficial effects of this utility model are: such a hedge trimming device has the advantages of cost saving and compact structure. Attached Figure Description
