Description

Technical Field

[0001] This utility model relates to the field of municipal equipment, and in particular to a municipal green belt trimming device. Background Technology

[0002] To ensure the aesthetic appeal of green belts, the vegetation is usually pruned according to the changing seasons. After pruning, the size and height of the vegetation are generally kept consistent, making the belts look neat and clean, greatly enhancing their aesthetic effect, and also facilitating vegetation growth.

[0003] Currently, when municipal departments carry out green belt pruning operations, they mainly rely on conventional equipment such as handheld electric hedge trimmers and small motorized pruning devices. These devices can trim the shape of hedges, shrubs, flower beds and other plants by the reciprocating sliding or rotating motion of the blades, meeting basic pruning needs.

[0004] However, existing municipal greenbelt pruning equipment still has key shortcomings in practical applications: most existing equipment only has a single pruning function and lacks a corresponding structure for the immediate collection of branches and leaves. During pruning, the cut branches and leaves are scattered directly on the surface of the greenbelt, between plants, or fall onto surrounding sidewalks, non-motorized vehicle lanes, and other areas. Because the branches and leaves cannot be collected simultaneously with the pruning, municipal departments need to arrange additional staff after the pruning work is completed to conduct secondary cleaning and collection using brooms, dustpans, and garbage trucks.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0022] Example 1 See Figures 1 to 4This utility model provides a municipal green belt trimming device, including a shell 1 with an internal storage space, and a drive motor 2 installed on one side of the shell 1; A mounting bracket 3 is fixedly installed on one side of the housing 1. The mounting bracket 3 is long and narrow. One end of the mounting bracket 3 is fixedly connected to the housing 1. Two blades 4 are slidably installed on the mounting bracket 3. The drive motor 2 drives the two blades 4 to work through the transmission component. Each blade 4 is provided with multiple serrations 5. Each serration 5 has a cutting edge on both sides. A collection hopper 6 is fixedly installed on one side of the mounting frame 3. The collection hopper 6 is funnel-shaped, with its large end fixedly connected to the mounting frame 3 and its small end detachably fitted with a collection bag 7.

[0023] The operator holds the equipment housing 1 and aligns the blade 4 with the municipal green belt area to be pruned. By starting the drive motor 2, the drive motor 2 transmits power to the two blades 4 through the transmission component, causing the two blades 4 to slide back and forth along the length of the mounting frame 3. At this time, the multiple serrated parts 5 on the blade 4 come into contact with the branches and leaves of the green belt, and the blades on both sides of the serrated parts 5 simultaneously cut the branches and leaves, achieving a neat pruning of the green belt.

[0024] During the pruning process, the cut branches and leaves fall into the collection hopper 6, which immediately collects and stores them in the collection bag 7, preventing the branches and leaves from scattering onto roads, sidewalks, or gaps in green belts, thus reducing pollution of the municipal environment. At the same time, it eliminates the secondary operation step of "separately cleaning up scattered branches and leaves" after traditional pruning, reducing the labor and time costs of municipal greening operations and improving overall operational efficiency.

[0025] The transmission assembly includes a drive gear 8 fixedly mounted on the motor shaft of the drive motor 2, and the drive gear 8 is located inside the housing 1; A driven gear 9 is rotatably disposed inside the housing 1, and the driven gear 9 meshes with the driving gear 8. An input gear 10 is fixedly disposed on the driven gear 9. An output gear 11 is rotatably disposed inside the housing 1, and the output gear 11 meshes with the input gear 10. An eccentric shaft 12 is fixedly installed on each side of the output gear 11. The two eccentric shafts 12 are symmetrically arranged on both sides of the axis of the output gear 11. A connecting rod 13 is rotatably installed on each eccentric shaft 12. Each connecting rod 13 is rotatably connected to one end of one of the blades 4.

[0026] After the drive motor 2 is started, the motor shaft drives the fixed drive gear 8 to rotate synchronously. The drive gear 8 drives the driven gear 9 to rotate. Under the action of the input gear 10, the output gear 11 is driven to rotate around its own axis, thus completing the multi-stage power transmission from the motor to the output gear 11.

[0027] When the output gear 11 rotates, the two eccentric shafts 12 on both sides of it, which are symmetrical about their own axis, move in a circular motion in sync with the output gear 11. The connecting rod 13 rotatably connected to each eccentric shaft 12 drives the blade 4 rotatably connected to itself to slide synchronously in opposite directions along the mounting frame 3. That is, when one blade 4 slides to one end of the mounting frame 3, the other blade 4 slides to the other end of the mounting frame 3, thereby realizing the cutting action of the branches and leaves of the green belt.

[0028] A leaf sweeper 14 is rotatably installed at the large end of the collection hopper 6. The leaf sweeper 14 includes a rotating shaft, the two ends of which are fixed on the collection hopper 6. Soft brushes for sweeping leaves are arranged in an array on the rotating shaft. An intermediate gear 15 is also rotatably disposed inside the housing 1. The intermediate gear 15 meshes with the driven gear 9, and the intermediate gear 15 is connected to the rotating shaft through the transmission rod 16.

[0029] After the drive motor 2 starts, the power is transmitted to the driven gear 9 through the drive gear 8. The driven gear 9 synchronously drives the intermediate gear 15 to rotate. The intermediate gear 15 transmits the power to the rotating shaft through the transmission rod 16, driving the rotating shaft to rotate around its own axis. The soft brushes arranged in an array on the rotating shaft rotate synchronously with the rotating shaft, forming a continuous sweeping action. This can actively sweep up the branches and leaves that have not fallen directly into the collection hopper 6 after being trimmed by the blade 4, avoiding the problem of incomplete collection caused by scattered branches and leaves in traditional equipment. This ensures the cleanliness of the environment around the municipal green belt and further reduces the cost of secondary cleaning.

[0030] A rectangular mounting frame 17 is fixedly installed at the opening of the collection bag 7, and the two ends of the mounting frame 17 are detachably connected to the collection hopper 6 by a buckle 18.

[0031] The collection bag 7 is detachably connected to the collection hopper 6 via a rectangular mounting frame 17 and a buckle 18, allowing for installation or disassembly without tools, thus improving installation efficiency. The rectangular mounting frame 17 and the small end of the collection hopper 6 have good shape compatibility, allowing for quick alignment of the connection position, reducing preparation time before operation and downtime during operation, thereby improving the efficiency of municipal greening operations.

[0032] The buckle 18 is fixedly mounted on the mounting base on the mounting frame 17. A hand pressure plate is rotatably mounted on the mounting base, and a locking hook is rotatably mounted in the middle of the hand pressure plate. A locking groove is provided on the collection hopper 6, and the locking hook engages with the locking groove.

[0033] First, align the locking hook on the mounting frame 17 with the locking groove on the collection hopper 6, press the hand pressure plate, and drive the locking hook to rotate around the middle of the hand pressure plate so that the locking hook is engaged in the locking groove; after releasing the hand pressure plate, the locking hook remains engaged with the locking groove under its own structural action, thus completing the fixing of the mounting frame 17 and the collection hopper 6.

[0034] A handle 19 is fixedly installed on the collection bucket 6.

[0035] When using this utility model, the operator holds the device housing 1 and aligns the blade 4 with the municipal green belt area to be pruned; by starting the drive motor 2, the drive motor 2 transmits power to the two blades 4 through the transmission component, causing the two blades 4 to slide back and forth along the length of the mounting frame 3; at this time, the multiple serrated parts 5 on the blade 4 come into contact with the branches and leaves of the green belt, and the blades on both sides of the serrated parts 5 simultaneously cut the branches and leaves, thus achieving the neat pruning of the green belt.

[0036] During the pruning process, the cut branches and leaves fall into the collection hopper 6, which immediately collects and stores them in the collection bag 7, preventing the branches and leaves from scattering onto roads, sidewalks, or gaps in green belts, thus reducing pollution of the municipal environment. At the same time, it eliminates the secondary operation step of "separately cleaning up scattered branches and leaves" after traditional pruning, reducing the labor and time costs of municipal greening operations and improving overall operational efficiency.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
