Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, and more specifically to a landscaping pruning device. Background Technology

[0002] With the acceleration of urbanization, the area of ​​urban green spaces is constantly increasing. Parks, streets, and residential areas in cities all require a large number of green plants to beautify the environment and purify the air. This necessitates more efficient and convenient pruning equipment to cope with the ever-increasing workload of green space maintenance in order to maintain the good landscape effect of urban greening.

[0003] When dealing with gaps between walls and plants, branches close to the ground, and spherical or wavy plants, a fixed-angle saw blade cannot align with the growth direction of the target branch. It is easily obstructed by the wall, ground, or the plant itself, resulting in "inadequate pruning." It is necessary to bend over or even squat to align the fixed-angle saw blade with the target. Prolonged operation can easily cause strain on the waist and knees. In addition, to prune branches at height, operators need to use ladders or stools to climb. When climbing, it is difficult to maintain balance, especially on uneven ground such as lawns and slopes, which can easily lead to slips and falls. Utility Model Content

In addition, the forms of the various structures described in the following embodiments are merely illustrative. The garden greening pruning device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figure 1-6 This utility model provides a garden greening pruning device, including a body component 1, a telescopic component 2 sleeved on one side of the body component 1, an adjustment component 3 installed at one end of the telescopic component 2, an external component 4 provided at the bottom of the adjustment component 3, and a pruning component 5 installed inside the external component 4.

[0025] Reference Figure 1-2 and Figure 5 The machine body component 1 includes a housing 101, a rod 102, a slide groove 103, and a handle 104. The rod 102 is fixedly installed on the left side of the housing 101, and slide grooves 103 are symmetrically opened on both sides of the inner wall of the rod 102. Multiple handles 104 are provided and fixedly installed on the right side of the housing 101 and the outer side of the rod 102, which allows the operator to conveniently operate the pruning device by holding the handles 104.

[0026] Reference Figure 1-3 , Figure 5 and Figure 6 The telescopic assembly 2 includes a telescopic rod 201, guide bars 202, a telescopic motor 203, and a threaded rod 204. Guide bars 202 are symmetrically arranged on both outer sides of the telescopic rod 201, and the telescopic rod 201 is slidably sleeved in the grooves 103 on both sides of the inner side of the rod body 102 via the guide bars 202. The telescopic motor 203 is nested inside the housing 101, and the output shaft of the telescopic motor 203 is fixedly sleeved on the threaded rod 204 via a coupling. The threaded rod 204 is threaded inside the telescopic rod 201, facilitating the starting of the telescopic motor 203. The output shaft of the telescopic motor 203 drives the transmission shaft to rotate, which in turn drives the threaded rod 204 to rotate. Under the rotation of the threaded rod 204, the telescopic rod 201 slides inside the rod body 102, causing the telescopic rod 201 to extend and retract. This extends the control adjustment assembly 3, the external assembly 4, and the pruning assembly 5, allowing workers to operate the device from a low position to prune the greenery at higher locations, avoiding the need for workers to climb to heights and pose safety hazards.

[0027] Reference Figure 1-2 , Figure 4 and Figure 6 The adjusting assembly 3 includes a fixed cavity 301, an adjusting motor 302, a first helical gear 303, a rotating shaft 304, a second helical gear 305, and a lug 306. The fixed cavity 301 is fixedly connected to the left end of the telescopic rod 201. The adjusting motor 302 is nested inside the left side of the telescopic rod 201, and the output shaft of the adjusting motor 302 is fixedly sleeved with the first helical gear 303 via a coupling. The first helical gear 303 is located inside the fixed cavity 301. The rotating shaft 304 movably passes through the inner cavity of the fixed cavity 301, and the second helical gear 305 is fixedly sleeved on the outer side of the rotating shaft 304. The second helical gear 305 meshes with the first helical gear 303. The lug 306... The components are symmetrically sleeved at both ends of the rotating shaft 304, specifically configured as fixed sleeves, and the lugs 306 are located on both sides of the outside of the fixed cavity 301. This facilitates the starting of the adjustment motor 302. The output shaft of the adjustment motor 302 drives the transmission shaft to rotate, which in turn drives the first helical gear 303 to rotate. The first helical gear 303 then drives the second helical gear 305, which meshes with it, to rotate. This controls the rotating shaft 304, lugs 306, external components 4, and pruning components 5 to rotate around the rotating shaft 304. This allows workers to adjust the angle of the pruning components 5 while standing still during the pruning process, reducing physical exertion, increasing the diversity of greening appearance pruning, and improving the landscape effect of the garden.

[0028] Reference Figure 1-2 and Figure 4The external component 4 includes a fixed housing 401, a weed guard 402, and an opening 403. The fixed housing 401 is fixedly installed at the bottom of the two side hanging ears 306. The weed guard 402 is fixedly sleeved on the outside of the fixed housing 401. An opening 403 is provided on one side of the fixed housing 401, which helps to block some flying branches and other objects during the trimming process, reducing the cleaning work after trimming.

[0029] Reference Figure 4 The pruning assembly 5 includes a pruning motor 501, a fixed plate 502, a saw blade 503, and fixing bolts 504. The pruning motor 501 is nested inside the fixed housing 401, and the output shaft of the pruning motor 501 is fixedly connected to the fixed plate 502 via a coupling. The saw blade 503 is located at the bottom of the fixed plate 502 and inside the weed cover 402 to prevent workers from being accidentally injured. The fixing bolts 504 are distributed in a ring in the fixed plate 502 and the saw blade 503, and the fixing bolts 504 can move through the fixed plate 502 and the saw blade 503, which is convenient for starting the pruning motor 501. The output shaft of the pruning motor 501 drives the transmission shaft to rotate, and the transmission shaft drives the fixed plate 502, the saw blade 503, and the fixing bolts 504 to rotate. Under the rotation and cutting of the saw blade 503, the landscaping is pruned. Workers can also remove and replace the fixing bolts 504 to ensure cutting efficiency.

[0030] The working principle of this utility model:

[0031] First, the staff hold the corresponding handles 104 with both hands, align the side of the opening 403 with the greenery to be pruned, and start the pruning motor 501. The output shaft of the pruning motor 501 drives the transmission shaft to rotate. The transmission shaft drives the fixed plate 502, saw blade 503 and fixing bolt 504 to rotate inside the weed cover 402. Under the rotation and cutting of the saw blade 503, the garden greenery is pruned. During the pruning process, some flying branches and other objects are blocked by the weed cover 402, reducing the cleaning work after pruning.

[0032] Secondly, the telescopic motor 203 is started. The output shaft of the telescopic motor 203 drives the transmission shaft to rotate, and the transmission shaft drives the threaded rod 204 to rotate. Under the rotation of the threaded rod 204, the telescopic rod 201 is pushed to slide inside the rod body 102, so that the telescopic rod 201 extends and retracts. The control adjustment component 3, the external component 4 and the pruning component 5 are extended, so that the staff can operate the device from a low position to prune the greenery at high positions, avoiding the need for the staff to climb to a height to operate.

[0033] Finally, start the adjusting motor 302. The output shaft of the adjusting motor 302 drives the transmission shaft to rotate. The transmission shaft drives the first helical gear 303 to rotate. The first helical gear 303 drives the second helical gear 305 that meshes with it to rotate. This controls the rotating shaft 304, the hanging ear 306, the external component 4 and the trimming component 5 to rotate around the rotating shaft 304. This allows the operator to adjust the angle of the trimming component 5 while standing still during the trimming process, increasing the versatility of the trimming. When the saw blade 503 becomes dull, the operator can remove the fixing bolt 504 and replace it.

[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
