Description

Technical Field

[0001] The present invention relates to the technical field of green belt pruning, and specifically, it is a self - adsorbing and grass - shredding synchronous - recovery green belt pruning machine. Background Technique

[0002] As an important part of the urban ecosystem, the green belt is a green space formed by orderly arranging various vegetation such as arbors, shrubs, and herbaceous plants according to scientific planning and aesthetic principles. It is widely distributed on both sides of roads. With the advancement of urban greening construction, the forms of green belts are becoming more diverse, posing higher requirements for the fine - operation ability of pruning equipment.

[0003] However, when facing green belts with different widths, heights, and branch distributions, traditional pruning equipment still adopts fixed parameters or manual adjustment modes. This extensive operation method not only makes it difficult to ensure the neatness and aesthetics of pruning, but also easily causes over - pruning or omission.

[0004] At the same time, in the context of pursuing high - efficiency operation, it is also impossible to incorporate the grass - shredding treatment into an integrated process. The environmental pollution problem caused by the scattered grass - shreds will also lead to a significant increase in subsequent cleaning costs. Moreover, in the face of irregularly growing branches at the top of the green belt, there is a lack of targeted treatment mechanisms, further restricting the integrity of the pruning operation. Summary of the Invention

[0005] The purpose of the present invention is to provide a self - adsorbing and grass - shredding synchronous - recovery green belt pruning machine to solve the problems mentioned in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A self - adsorbing and grass - shredding synchronous - recovery green belt pruning machine, including an adapter frame connected to the robotic arm of an external mobile vehicle. The bottom end of the adapter frame is fixedly connected with a support base. Both side walls of the support base are fixedly connected with support frames for supporting the rotation of the distance - adjusting mechanism, and a longitudinal cutting mechanism for longitudinally cutting the green belt is provided at the end of the support frame far from the support base.

[0007] A transverse cutting mechanism for transversely cutting the top of the green belt is provided at the forward end of the adapter frame. A first grooming mechanism for grooming the green belt in the early stage and a second grooming mechanism for grooming the green belt in the later stage are respectively fixedly connected to the forward end and the rear end of the adapter frame.

[0008] Furthermore, the distance - adjusting mechanism includes a sliding plate and a vertical plate frame. A sliding groove for the horizontal sliding of the sliding plate is opened at the middle position of the support base, and a first toothed plate is fixedly connected to the bottom of the sliding plate.

[0009] At the bottom of the support base and on both sides of the chute, there are first support plates fixedly connected. Inside the two first support plates, a first gear meshing and driving with the first toothed plate is movably connected through bearings. On the outer sides of the two first support plates, there is a flipping seat, and the flipping seat is fixedly connected to the side wall of the first gear through a short shaft;

[0010] At the bottom of the support frame, there is a second support plate fixedly connected. One end of the second support plate is movably connected to a rotating rod through a bearing, and a flipping sleeve is fixedly sleeved on the outer side of the rotating rod.

[0011] Furthermore, the inner side wall of the flipping seat is movably connected to a flipping block through a bearing. One end of the rotating rod close to the flipping block is fixedly connected to a fixing seat, and the inner side wall of the fixing seat is rotationally connected to the outer side of the flipping block. An adjusting rod is slidably connected inside the flipping sleeve, and one end of the adjusting rod is fixedly connected to the vertical plate frame. At the bottom of the flipping sleeve in the unfolded state, there is an electric push rod one for driving the adjusting rod to move.

[0012] Furthermore, the longitudinal cutting mechanism is composed of multiple groups of longitudinal electric rotary cutters, and the longitudinal electric rotary cutters are fixedly installed on the side wall of the vertical plate frame. The transverse cutting mechanism is composed of multiple groups of transverse electric rotary cutters.

[0013] Furthermore, on the two opposite side walls of the connecting frame, an electric lifting mechanism one and an electric lifting mechanism two are respectively fixedly installed. The front end of the electric lifting mechanism one and the rear end of the electric lifting mechanism two are respectively connected to a first frame and a second frame. A translation plate is slidably connected in two mutually parallel limiting grooves at the bottom of the first frame and the second frame. The transverse electric rotary cutter is fixedly installed at the bottom of the translation plate below the first frame.

[0014] Furthermore, the carding mechanism one and the carding mechanism two are respectively composed of a front carding frame and a rear carding frame, and the front carding frame and the rear carding frame are respectively fixedly connected to the outer sides of the corresponding translation plates.

[0015] Furthermore, a negative pressure suction pipe one and a negative pressure suction pipe two are respectively fixedly installed at positions near the bottom end of the outer side wall of the vertical plate frame and on the outer side of the translation plate below the second frame.

[0016] Furthermore, a second gear is movably connected through bearings inside both the first frame and the second frame. On one adjacent side of the two translation plates, a second toothed plate meshing and driving with the second gear is fixedly installed.

At the top of the connecting frame, an electric push rod two is fixedly installed, and the output end of the electric push rod two is fixedly connected to the convex block at the top of the sliding plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The multi-dimensional adaptive pruning mechanism realizes precise and efficient operation: Through the linkage cooperation of the distance adjustment mechanism, the longitudinal and transverse cutting mechanisms, and the first and second electric lifting mechanisms, the equipment can perform three-dimensional space adjustment according to the actual size of the green belt: The meshing transmission between the sliding plate and the first gear in the distance adjustment mechanism drives the flipping seat and the flipping sleeve frame to rotate, enabling the vertical plate frame to flexibly switch from the horizontal storage state to the vertical operation state. Cooperating with the first electric push rod to drive the distance adjustment rod to adjust the distance between the vertical plate frames, it realizes the precise fitting and pruning of the sides of green belts with different widths by the longitudinal electric rotary cutters on both sides.

[0019] The transverse electric rotary cutter independently adjusts its height through the electric lifting mechanism, and drives the translation plate to move synchronously and in the opposite direction to expand the pruning width by means of the meshing transmission between the second gear and the second toothed plate. Combining with the front combing frame whose direction can be flexibly adjusted to guide the bending branches at the top of the green belt, it ensures the all-round and dead-angle-free pruning of the top and sides, significantly improving the pruning quality and operation adaptability.

[0020] 2. The synchronous adsorption, recycling of shredded grass and automatic control improve the operation efficiency: The integrated first and second negative pressure suction pipes of the equipment are respectively aimed at the shredded grass generated by the pruning of both sides and the top of the green belt, and realize the immediate adsorption and recycling through connection with the external dust suction mechanism. Cooperating with the rear combing frame to level and comb the top after pruning, under the automatic linkage of each mechanical structure, it realizes the full-automatic operation from the flipping and distance adjustment of the vertical plate frame, the adjustment of the height and width of the cutting mechanism to the direction adjustment of the combing frame. It can quickly switch the equipment posture and operation parameters without manual intervention. Under the coordinated control of the mechanical arm of the external mobile vehicle, it can move stably along the length direction of the green belt and synchronously complete pruning and shredded grass recycling, significantly improving the operation efficiency and reducing the subsequent cleaning cost.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: As Figures 1-7 shown, a self-adsorbing grass-shredding and synchronous recycling green belt trimming machine includes a connecting frame 1 connected to the mechanical arm of an external mobile vehicle. The bottom end of the connecting frame 1 is fixedly connected to a support base 2. Both side walls of the support base 2 are fixedly connected to support frames 3 for supporting the rotation of the distance adjusting mechanism. One end of the support frame 3 away from the support base 2 is provided with a longitudinal cutting mechanism for longitudinally cutting the green belt;

[0032] The front end of the connecting frame 1 is provided with a transverse cutting mechanism for transversely cutting the top of the green belt. The front end and the rear end of the connecting frame 1 are also respectively fixedly connected with a first combing mechanism for pre-combing the green belt and a second combing mechanism for post-combing the green belt.

[0033] The distance adjusting mechanism includes a sliding plate 601 and a vertical plate frame 607. A chute for the horizontal sliding of the sliding plate 601 is opened at the middle position of the support base 2. The bottom of the sliding plate 601 is fixedly connected with a first toothed plate. On both sides of the chute at the bottom of the support base 2, first support plates are fixedly connected. Inside the two first support plates, a first gear 602 meshing and driving with the first toothed plate is rotatably connected through a bearing. On the outside of the two first support plates, a flipping seat 603 is provided. The flipping seat 603 is fixedly connected to the side wall of the first gear 602 through a short shaft;

[0034] The bottom of the support frame 3 is fixedly connected with a second support plate. One end of the second support plate is movably connected with a rotating rod through a bearing. The flipping sleeve frame 4 is sleeved and fixed on the outer side of the rotating rod.

[0035] The inner side wall of the flipping seat 603 is movably connected with a flipping block 605 through a bearing. One end of the rotating rod close to the flipping block 605 is fixedly connected with a fixing seat 604. The inner side wall of the fixing seat 604 is rotationally connected with the outer side of the flipping block 605. A distance adjusting rod 606 is slidably connected inside the flipping sleeve frame 4. One end of the distance adjusting rod 606 is fixedly connected with a vertical plate frame 607. The bottom of the flipping sleeve frame 4 in the unfolded state is fixedly connected with a first electric push rod 608 for driving the distance adjusting rod 606 to move. With the mutual cooperation of the first electric push rod 608, the distance adjusting rod 606 and the flipping sleeve frame 4, the vertical plate frame 607 will maintain better stability during use.

[0036] Embodiment 2: The longitudinal cutting mechanism is composed of multiple groups of longitudinal electric rotary cutting knives 701, and the longitudinal electric rotary cutting knives 701 are fixedly installed on the side wall of the vertical plate frame 607. The transverse cutting mechanism is composed of multiple groups of transverse electric rotary cutting knives 702.

[0037] Two opposite side walls of the connecting frame 1 are respectively fixedly installed with a first electric lifting mechanism 801 and a second electric lifting mechanism 802. The front end of the first electric lifting mechanism 801 and the rear end of the second electric lifting mechanism 802 are respectively connected with a first frame 901 and a second frame 902. A translation plate 10 is slidably connected in two mutually parallel limiting grooves at the bottom of the first frame 901 and the second frame 902. The transverse electric rotary cutting knives 702 are fixedly installed at the bottom of the translation plate 10 below the first frame 901. It should be explained here that:

[0038] The first electric lifting mechanism 801 and the second electric lifting mechanism 802 have the same structure and are existing structures, and both are composed of a track frame, a threaded rod, a lifting seat and an external servo motor. The track frames are respectively fixed on two opposite side walls of the connecting frame 1. The two ends of the threaded rod are movably connected inside the track frame through bearings. A servo motor for rotating the threaded rod is fixedly installed inside the track frame. The correspondingly arranged lifting seats are respectively fixedly connected with the side walls of the first frame 901 and the second frame 902. The lifting seats are threadedly connected with the threaded rod by using their own thread grooves. The servo motor drives the threaded rod to rotate, and further drives the correspondingly connected first frame 901 and the second frame 902 to perform independent lifting through the lifting seats.

[0039] The carding mechanism one and the carding mechanism two are respectively composed of a front carding frame 11 and a rear carding frame 12. The front carding frame 11 and the rear carding frame 12 are respectively fixedly connected to the outside of the corresponding translation plate 10. It should be explained here that the two translation plates 10 below the first frame 901 are both fixedly connected with the front carding frame 11, and the installation direction of the front carding frame 11 is flexible. The bottom ends of the front carding frame 11 can all face the advancing direction of the whole device, and the front carding frame 11 will not hinder the rotation of the transverse electric rotary cutter 702. It can also all face the reverse direction of the whole position's hind legs, or half face the advancing direction of the whole device and half face the reverse direction of the whole position's hind legs. Similarly, the rear carding frame 12 below the second frame 902 can also be adjusted flexibly.

[0040] A first negative pressure suction pipe 501 and a second negative pressure suction pipe 502 are respectively fixedly installed at the position near the bottom end of the outer side wall of the vertical plate frame 607 and on the outer side of the translation plate 10 below the second frame 902. The first negative pressure suction pipe 501 and the second negative pressure suction pipe 502 are both connected to an external dust suction mechanism. The first negative pressure suction pipe 501 and the second negative pressure suction pipe 502 are respectively used to absorb the chopped grass that falls on both sides and the top of the green belt after pruning.

[0041] A second gear 13 is movably connected to the inside of both the first frame 901 and the second frame 902 through bearings. Second toothed plates that are meshed and driven with the second gear 13 are fixedly installed on one adjacent side of the two translation plates 10. A motor for driving the second gear 13 to rotate is fixedly installed on the top of the first frame 901. An electric push rod two 14 is fixedly installed on the top of the connecting frame 1. The output end of the electric push rod two 14 is fixedly connected to the convex block on the top of the sliding plate 601. The motor drives the second gear 13 to rotate, and through the mutual meshing of the second gear 13 and the second toothed plate, the two corresponding translation plates 10 are driven to move synchronously and in opposite directions.

[0042] Combined with Embodiment 1 and Embodiment 2, it can be seen that the external mobile vehicle robotic arm controls the connecting frame 1 to move to directly above the green belt to be pruned. The electric push rod two 14 is started and further drives the sliding plate 601 to slide inside the support seat 2. The first gear 602 rotates under the action of the first toothed plate at the bottom of the sliding plate 601. The first gear 602 drives the flipping seat 603 to rotate synchronously through a short shaft. During the rotation of the flipping seat 603, the rotating rod and the flipping sleeve frame 4 are driven to rotate synchronously through the mutual cooperation of the flipping block 605 and the fixing seat 604. The flipping sleeve frame 4 further drives the vertical plate frame 607 to deflect synchronously through the distance adjusting rod 606 and the electric push rod one 608 until the vertical plate frame 607 is flipped from the horizontal state to the vertical state, as Figure 1 shown. The vertical plate frame 607 deflects flexibly for flexible storage and is convenient for transportation after pruning.

[0043] Subsequently, the distance between the two vertical plate frames 607 is adjusted according to the width of the green belt to be pruned. Specifically, the vertical plate frame 607 is driven to move by the first electric push rod 608. During the movement of the vertical plate frame 607, the distance adjustment rod 606 is driven to move horizontally in the flipping sleeve 4 until the longitudinal electric rotary cutter 701 inside the vertical plate frame 607 approaches both sides of the green belt and prunes the green belt.

[0044] While pruning both sides of the green belt, it is also necessary to prune the upper part of the green belt. Therefore, the height of the transverse electric rotary cutter 702 is adjusted according to the height of the green belt to be pruned. Specifically, the first frame 901 drives the transverse electric rotary cutter 702 to lift and lower synchronously until the transverse electric rotary cutter 702 approaches the specified position above the green belt. The motor drives the second gear 13 to rotate, and the translation plate 10 located below the first frame 901 moves synchronously and reversely under the mutual meshing of the second gear 13 and the second toothed plate until the pruning range of the transverse electric rotary cutter 702 covers the width of the green belt.

[0045] The external moving vehicle controls the connecting frame 1 to move along the length direction of the green belt through the robotic arm, and the transverse electric rotary cutter 702 and the longitudinal electric rotary cutter 701 synchronously prune the top and side edges of the green belt.

[0046] Before pruning the upper part of the green belt, since there are branches with different growth conditions inside the green belt, some branches are in a bent state inside the green belt. Therefore, multiple groups of front combing frames 11 are provided to comb the bent branches near the top of the green belt, so that they extend from the inside to the upper part of the green belt, facilitating the transverse electric rotary cutter 702 to prune them.

[0047] The second negative pressure suction pipe 502 absorbs the chopped grass above the green belt, and the rear combing frame 12 behind can comb the top of the pruned green belt. Through the mutual cooperation of the first negative pressure suction pipe 501 and the second negative pressure suction pipe 502, it is possible to comprehensively adsorb the chopped grass generated by pruning the green belt.

[0048] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the relevant technical fields can understand and utilize the present invention well.
