Description

Green belt trimmer

Technical Field

The utility model relates to a afforestation trimming means especially relates to a greenbelt trimming machine.

Background

The green belt is a facility for separating road traffic, which saves materials and is environment-friendly, although the green belt is small, the green belt is widely distributed, and can eliminate the driving fatigue of drivers, beautify the environment and ensure the traffic safety. Regular pruning is a common measure for maintaining the attractiveness and functions of green belts, and the pruning of road green belts in most cities is completed by manpower or old machines, so that time and labor are wasted, and a novel machine meeting the actual requirements is urgently needed along with the increasing area of the green belts. Patent document CN 207099782U discloses a green belt trimmer, but it can only trim the upper side or the side, and cannot trim the green belt in two directions at the same time, and there may be an obstacle (guidepost, street lamp, etc.) in the middle of the green belt, so the trimmer satisfying the two-way simultaneous trimming needs to be able to avoid the obstacle, and the efficiency can be improved really.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned prior art defect, the task of the utility model lies in providing a greenbelt trimmer realizes that top and side prune simultaneously and can avoid the barrier.

The utility model discloses technical scheme is such: the utility model provides a greenbelt trimmer, includes dolly, top surface trimming mechanism and side trimming mechanism, fixedly connected with support on the dolly, be equipped with longitudinal rail on the support, be equipped with preceding horizontal arm on the longitudinal rail and can follow the gliding back arm cover of longitudinal rail, the head end of preceding horizontal arm is equipped with vertical axle, vertical epaxial cover be equipped with the eccentric shaft that vertical axle is parallel, vertical axle with be equipped with torsion spring between the eccentric shaft, the bottom of eccentric shaft with top surface trimming mechanism fixed connection, the fixed vertical arm that is equipped with of back arm cover, be equipped with slidable lower arm cover on the vertical arm, the lower arm is sheathe in and is equipped with back horizontal arm, the head end of back horizontal arm with side trimming mechanism fixed connection.

Furthermore, a front arm sleeve is fixed on the longitudinal guide rail, and the front transverse arm is fixedly connected with the front arm sleeve.

Furthermore, the front transverse arm and the rear transverse arm are both hydraulic telescopic rods.

Further, the top surface trimming mechanism comprises a cuboid cover with an opening in the bottom surface, a front trimming motor and a front trimming knife are arranged in the cuboid cover, the front trimming motor drives the front trimming knife to rotate, and the trimming surface of the front trimming knife is arranged downwards.

Further, the side trimming mechanism comprises an 8-shaped side plate, a baffle is arranged on the rear side of the 8-shaped side plate, a rear front trimming motor and a rear trimming knife are arranged on the 8-shaped side plate, the rear trimming motor drives the rear trimming knife to rotate, and the trimming surface of the rear trimming knife is arranged towards the transverse side surface.

Compared with the prior art, the utility model the advantage lie in: through with vertical axle parallel arrangement eccentric shaft, when top surface trimming means met the obstacle, can dodge for the eccentric rotation of axis around vertical axle, realized top and side and pruned simultaneously and can straight line carry out and need not to make the dolly make the effect of dodging the obstacle action alone, improved greenbelt pruning efficiency. In addition, the relative position relationship between the top surface trimming mechanism and the side surface trimming mechanism can be adjusted through the actions of the front transverse arm and the rear transverse arm and the sliding of the rear arm sleeve, so that green belts with different shapes can be trimmed conveniently.

Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Referring to fig. 1 and 2, the green belt trimmer according to the present embodiment includes a cart 1, a top trimming mechanism and a side trimming mechanism. The trolley 1 is a four-wheel trolley, which is convenient for the propulsion of green belt pruning operation. The trolley 1 is fixedly connected with a support 2, the support 2 can be used as a suspension frame for four wheels of the trolley 1 and also used as a main operation handrail for workers, the specific form of the support 2 has no fixed requirement, and only the most basic tubular components are shown in the drawing of the embodiment. The support 2 is provided with a longitudinal guide rail 3, a front arm sleeve 4 is fixed on the longitudinal guide rail 3, and the front arm sleeve 4 is provided with a front transverse arm 5. The longitudinal guide rail 3 is also provided with a rear arm sleeve 6 which can slide along the longitudinal guide rail 3. The rear arm sleeve 6 is fixedly provided with a vertical arm 7, the vertical arm 7 is provided with a slidable lower arm sleeve 8, and the lower arm sleeve 8 is provided with a rear transverse arm 9. The front transverse arm 5 and the rear transverse arm 9 are both hydraulic telescopic rods, namely the front transverse arm 5 and the rear transverse arm 9 can be adjusted in length. The head end of preceding horizontal arm 5 is equipped with vertical axle 10, and the cover is equipped with the eccentric shaft 11 parallel with vertical axle 10 on vertical axle 10, and eccentric shaft 11 can use vertical axle 10 to carry out circular motion as the pivot. A torsion spring 12 is arranged between the vertical shaft 10 and the eccentric shaft 11, when the eccentric shaft 11 receives external force and performs circular motion by taking the vertical shaft 10 as a rotating shaft, the torsion spring 12 is compressed, and when the external force is removed, the eccentric shaft 11 is reset to the original position. The bottom of the eccentric shaft 11 is fixedly connected with the top surface trimming mechanism, and the head end of the rear transverse arm 9 is fixedly connected with the side surface trimming mechanism. The top surface trimming mechanism comprises a cuboid cover 13 with an opening on the bottom surface, a front trimming motor 14 and a front trimming cutter 15 are arranged in the cuboid cover 13, the front trimming motor 14 is used for driving the front trimming cutter 15 to rotate, and the trimming surface of the front trimming cutter 15 is arranged downwards. The connecting point of the eccentric shaft 11 and the top trimming mechanism deviates from the center of gravity of the top rectangle of the rectangular parallelepiped cover 13, in this embodiment, two front trimming motors 14 are arranged side by side, and the eccentric shaft 11 is located above one of the front trimming motors 14. The side pruning mechanism includes 8 style of calligraphy curb plate 16, and 8 style of calligraphy curb plate 16's rear side sets up baffle 17, and this baffle 17 mainly blocks the twig under the pruning and flies to operating personnel. The 8-shaped side plate 16 is provided with a rear front trimming motor 18 and a rear trimming blade 19, the rear trimming motor 18 is used for driving the rear trimming blade 19 to rotate, and the trimming surface of the rear trimming blade 19 is arranged towards the transverse side. The green belt trimmer can adjust the relative position between the top trimming mechanism and the side trimming mechanism through the extension and retraction of the front transverse arm 5 and the rear transverse arm 9 and the position of the lower arm sleeve 8 on the vertical arm 7 so as to meet different requirements for green belts. When encountering an obstacle in the center of the greening rate in the pruning process, the obstacle generates acting force on the front side of the top surface pruning mechanism, and the eccentric shaft 11 drives the top surface pruning mechanism to rotate by taking the vertical shaft 10 as a rotating shaft to avoid the obstacle. After the top trimming mechanism passes over an obstacle, the eccentric shaft 11 drives the top trimming mechanism to reset under the action of the torsion spring 12.
