Flowering branches at the upper end of the green belt are trimmed to be flat through the collecting device and the trimming knife set which are coaxially arranged, and the trimmed green plants are collected in a step-by-step pushing mode, so that possible potential safety hazards caused by the fact that the flowering branches fall into the expressway surface are effectively avoided. The collecting device can be driven in an auxiliary mode through wind power, motor loads can be reduced, and the service life of the device is prolonged.

Description

Technical Field

[0001] The present application relates to the field of green belt pruning equipment, and in particular to a device for pruning flower branches in a highway green belt. Background Art

[0002] Highway green belts beautify the surrounding environment by planting trees, lawns and flowers, making the scenery more charming during driving. At the same time, as a protective barrier, they can reduce the impact of natural disasters such as wind, sand and avalanches on the road, and can also reduce the visual interference between vehicles on both sides, improving driving safety. Therefore, it is necessary to trim the highway green belts. In the current trimming work, there is no effective means to collect the cut green plants. After trimming, they fall on the highway lanes, causing major driving safety hazards. In addition, the broken plants left at the upper end of the green belt also affect the appearance. For example, a highway green belt trimming robot with a publication number of CN110149941A includes a moving mechanism, a base, and a vertical telescopic machine. The robot comprises a structure, a horizontal telescopic mechanism, a cutter disc angle adjustment mechanism, a cutter disc mechanism and an electric control box; wherein the mobile machine is used to realize the movement of the entire robot in any horizontal direction and rotation in situ; the base is fixedly mounted on the top of the mobile mechanism, the vertical telescopic mechanism is vertically fixedly mounted on the top of the base, and the vertical telescopic machine is used to realize the lifting and lowering movement of the cutter disc mechanism in the vertical direction; the horizontal telescopic mechanism is laterally fixedly mounted on the top of the vertical telescopic mechanism, and the horizontal telescopic mechanism is used to realize the telescopic movement of the cutter disc mechanism in the horizontal direction; a cutter disc angle adjustment mechanism is fixedly mounted on the end of the horizontal telescopic mechanism, and the cutter disc angle adjustment mechanism is rotatably connected to the cutter disc mechanism, and the cutter disc angle adjustment mechanism is used to realize the angle adjustment of the cutter disc mechanism in the vertical plane. The above-mentioned pruning device cannot collect and gather the cut green plants, and cannot play a role in improving road driving safety. Therefore, the present application designs a flower branch pruning device for highway green belts that can collect and gather the pruned green plants and improve the service life of the device.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figures 1 to 4 As shown, the utility model provides the following technical solutions: a device for pruning flower branches in a highway green belt, comprising a frame 1, a pruning blade group 2, a transmission device 3, a storage box 4, and a collection device 5 for pushing and collecting the cut green plants step by step; the transmission device 3 is fixedly arranged on the upper part of the frame 1 and extends into the frame 1, the pruning blade group 2 is fixedly connected to the output end of the transmission device 3, and the collection device 5 is connected to the middle gear of the transmission device 3; the transmission device 3 and the pruning blade group 2 are three groups, which are evenly distributed along the frame 1. A connector 11 for connecting a telescopic control rod is provided on the upper part of the frame 1 to achieve the connection between the equipment and the vehicle-mounted telescopic arm and obtain electric drive. A scraper 12 for scraping the collection device 5 is provided inside the frame 1. The scraper 12 is arranged inside the frame 1 near the side of the collection pipe 51 to prevent the cut branches and leaves from being thrown out of the device due to the rotation of the collection device 5.

[0016] As another example, Figure 1 , Figure 3 and Figure 4The transmission device 3 shown includes a motor 31, a rotating rod 32, and a reducer 33 that makes the collecting device 5 rotate at a uniform speed. The upper end of the rotating rod 32 is fixedly connected to the output end of the motor 31, the lower end of the rotating rod 32 is fixedly connected to the pruning knife group 2, and the reducer 33 is fixedly connected to the middle of the rotating rod 32. The reducer 33 includes a fixed gear 331, a reduction gear 332, a fixed rod 333, and an outer wheel 334. The middle of the fixed gear 331 is fixedly connected to the rotating rod 32, the reduction gear 332 is meshed with the fixed gear 331, and the outer wheel 334 is provided with meshing teeth inside. The reduction gear 332 is meshed with the outer wheel 334, so that the rotating rod 32 drives the shear blade 21 to rotate and drives the collecting device 5 to rotate, and the cut branches and leaves are rotated and collected to avoid the branches and leaves from splashing. The reducer 33 reduces the rotation speed of the outer wheel 334 through the transmission of each gear, so that the collecting device 5 rotates at a suitable speed. The upper end of the fixing rod 333 is fixedly connected to the frame 1 , and the lower end of the fixing rod 333 is rotatably connected to the middle of the reduction gear 332 to prevent the transmission device 3 from moving up and down and ensure the normal operation of the reducer 33 .

[0017] As another example, Figure 1 and Figure 3 As shown, the collecting device 5 includes a collecting pipe 51 and a brush 52. One end of the collecting pipe 51 is fixedly connected to the frame 1, and the other end of the collecting pipe 51 extends into the storage box 4; the brush 52 is fixedly connected to the outer wheel 334. The frame 1 adopts a horizontal tilt design. When the device moves forward during operation, the wind gathers at the rear of the frame 1 and moves toward the collecting pipe 51 along the horizontal tilt of the frame 1, thereby assisting in pushing the branches and leaves into the collecting pipe 51, and assisting in driving the brush 52 to drive the outer wheel 334 to rotate, thereby reducing the motor load. The pruning knife group 2 includes a shearing blade 21 for shearing green plants in the green belt and a protective plate 22 for preventing the shearing blade 21 from rotating to form an updraft to disturb the cut branches and leaves. The middle part of the shearing blade 21 is fixedly connected to the lower end of the rotating rod 32, and the protective plate 22 is arranged on the upper part of the shearing blade 21. The brush 52 is arranged along the circumference of the outer wheel 334 to push the cut branches and leaves step by step into the collecting pipe 51. The brushes 52 are staggered to clean each other and prevent the branches and leaves from splashing.

[0018] Working principle: When in use, first place the storage box 4 on the vehicle, connect it to the vehicle-mounted telescopic arm through the connector 11, place the device above the high-speed green belt to be trimmed and start the device, drive the rotating rod 32 through the motor 31 to drive the shear blade 21 to rotate and cut the green belt, reduce the speed of the coaxially arranged collection device 3 through the set reducer 33 so that the brush 52 rotates the cut branches and leaves into the frame 1, and pushes them into the collection pipe 51 step by step. As the vehicle moves forward, the wind force generated moves toward the collection pipe 51 with the horizontal inclination of the frame 1, and the auxiliary brush 52 pushes the cut branches and leaves to the collection pipe 51, and the auxiliary brush 52 drives the outer wheel 334 to rotate. The cut branches and leaves finally fall into the storage box 4 through the collection pipe 51, completing the trimming of the green belt and the collection of the cut branches and leaves.
