Description

Technical Field

[0001] The present invention relates to the technical field of driving mechanisms, in particular to a driving mechanism. Background Art

[0002] With the continuous development of urban greening construction, the work of pruning roadside vegetation has become more and more arduous. At present, there are more large-scale vehicle-mounted equipment with mechanical arms and small handheld equipment on the market. The use of large-scale vehicle-mounted equipment is more restricted by environmental conditions, and the pruning efficiency of small handheld equipment is relatively low. Small and medium-sized vehicle-mounted equipment is more popular. However, all vehicle-mounted equipment is basically set to a foldable structure in order to reduce the space occupied and facilitate transportation. Summary of the invention

[0003] In view of the above problems, the present invention provides a driving mechanism.

[0004] The technical solution of the present invention is as follows:

[0005] A driving mechanism comprises a carrying platform and a horizontal frame arranged on the carrying platform, one end of the horizontal frame is rotatably provided with a rotating platform driven by a rotating motor, the rotating platform is used to install a pruning saw blade, the rotating plane of the pruning saw blade is parallel to the extension direction of the horizontal frame, and the pruning saw blade is provided with a driving motor that can drive its movement. In order to prevent the rotating platform from accidentally rotating during the pruning work, an anti-rotation pin can be provided to prevent it from rotating. A space for carrying the pruning saw blade is reserved on the carrying platform at the front side of the horizontal frame; it also includes a protective cover, which is a long strip groove structure that can cover the pruning saw blade, a slide rail is provided on the top of the horizontal frame, the extension direction of the slide rail is perpendicular to the rotation plane of the pruning saw blade, a slider is provided on the slide rail, and the slider is hinged to one side of the protective cover through a hinge, and a telescopic push rod is provided on the carrying platform to push the slider to slide along the slide rail.

[0006] The working principle of the above technical solution is as follows:

[0007] The driving mechanism of the present invention installs the pruning saw blade on a rotating platform. When not in use, the pruning saw blade can be driven by a rotating motor to rotate, recycle and fold, and is carried by the front end of the carrying platform. In addition, the present invention is also provided with a protective cover. When pruning is performed, the protective cover is opened and the protective cover is pulled backward along the slide rail by a telescopic push rod (electric) to expose the pruning saw blade. When not in use, the pruning saw blade is rotated and folded, and the telescopic push rod is started to push the protective cover forward. When it is pushed to the end of the slide rail, the protective cover is rotated downward to cover the pruning saw blade, thereby isolating and protecting the pruning saw blade, thereby preventing the pruning saw blade from being damaged by foreign objects and avoiding scratches on personnel by the pruning saw blade, thereby improving the safety of the pruning machine.

[0008] In a further technical solution, a plurality of connecting holes are provided on the front side surface of the cross bar along its extension direction, a connecting plate is provided on the bearing platform, a through hole is provided on the connecting plate, and the cross frame is detachably connected to the bearing platform by bolts passing through the through holes and the connecting holes. The cross frame and the bearing platform are combined in a detachable connection manner, which is convenient for adjustment to different pruning environments and can meet more pruning needs.

[0009] In a further technical solution, at least one group of baffles is provided on the part of the supporting platform used for supporting the pruning saw blade, and each group of baffles consists of two baffles arranged in parallel. The baffles are perpendicular to the extension direction of the cross frame. The baffles are provided on the one hand to limit the pruning saw blade, and on the other hand, the baffles located on the inner side can also play a role in fitting and limiting the cross frame, making positioning and installation more convenient.

[0010] In a further technical solution, a locking plate is hinged on one side of the protective cover, a locking hole is provided on the locking plate, and a locking column that can cooperate with the locking hole is provided on the front side of the supporting platform. Through the cooperation between the locking plate and the locking column, the protective cover can be prevented from being accidentally lifted up, thereby improving the safety of use.

[0011] In a further technical solution, a connecting assembly for connecting to a hauling mechanism (pruning tractor, etc.) is provided on the carrying platform.

[0012] The beneficial effects of the present invention are:

[0013] 1. The driving mechanism of the present invention installs the pruning saw blade on a rotating platform. When not in use, the pruning saw blade can be driven by a rotating motor to rotate, recycle and fold, and is carried by the front end of the carrying platform, thereby reducing the occupied space;
