Specific embodiments

[0036] 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.

[0037] As Figure 1 shown, the present invention provides a building greening maintenance device, including a base 1 and a blade 2 located outside the base 1. A transformation mechanism for driving the blade 2 to rotate in different states is provided on the base 1.

[0038] Among them, support legs with moving rollers are fixedly installed on the lower surface of the base 1, and a hand-held support is fixedly installed on the side of the base 1 to facilitate the staff to push the base 1 to move.

[0039] By setting the transformation mechanism, the blade 2 can be driven to be parallel to the ground and rotate to trim the lawn, and the distance between the blade 2 and the ground can be adjusted as needed, so as to adjust the trimming degree of the lawn;

[0040] It can also drive the blade 2 to be perpendicular to the ground and rotate to trim the side of the green belt, and the side of the green belt can be trimmed neatly;

[0041] It can also drive the blade 2 to be parallel to the ground and rotate away from the ground to trim the top surface of the green belt, and can also adjust the overall height of the blade 2 to facilitate adaptation to green belts of different heights.

[0042] As Figure 1 and Figure 2 shown, the transformation mechanism includes a bearing plate 31 fixed on the side wall of the base 1. The surface of the bearing plate 31 is provided with a vertically distributed first vertical groove 32 and a second vertical groove 33, and a semicircular movable groove 34 communicating with the first vertical groove 32 and the second vertical groove 33. The lengths of the first vertical groove 32 and the second vertical groove 33 are the same.

[0043] As Figure 1 and Figure 2 shown, a disc 35 is rotatably connected to the bearing plate 31 between the first vertical groove 32 and the second vertical groove 33. A rectangular rod 36 is inserted through the disc 35 in a telescopic manner. One end of the rectangular rod 36 is telescopically inserted with a long rod 37. The end of the long rod 37 away from the rectangular rod 36 is rotatably connected to a U-shaped seat 38. The blade 2 is rotatably connected to the U-shaped seat 38. The distance between the lower end of the disc 35 and the first vertical groove 32 is equal to the distance between the upper end of the disc 35 and the second vertical groove 33. The centers of the semicircular movable groove 34 and the disc 35 are the same origin.

[0044] Among them, the blade 2 is driven to rotate by an external motor.

[0045] As Figure 1 、 Figure 2 and Figure 3 shown, a strip-shaped frame 39 is rotatably connected to the surface of the bearing plate 31. The center position of the rotating shaft of the strip-shaped frame 39 and the center position of the disc 35 are on the same horizontal line. A sliding column 310 slidably adapted to the strip-shaped frame 39 is rotatably connected to the surface of the rectangular rod 36. The sliding column 310 is slidably adapted to the first vertical groove 32, the second vertical groove 33 and the semicircular movable groove 34.

[0046] Among them, the strip-shaped frame 39 is driven by an external motor;

[0047] As the strip-shaped frame 39 rotates, it can push the sliding column 310 to move in the first vertical groove 32, the semicircular movable groove 34 and the second vertical groove 33;

[0048] When the sliding column 310 is located at the connection of the semicircular movable groove 34 and the first vertical groove 32, the rectangular rod 36 and the long rod 37 are in a vertical state. At this time, the blade 2 is close to the ground and parallel to the ground, and the blade 2 can trim the lawn when rotating;

[0049] When the sliding column 310 moves up and down in the first vertical groove 32, it can drive the rectangular rod 36, the long rod 37, the U-shaped seat 38 and the blade 2 to move upward together, adjusting the distance between the blade 2 and the ground, so as to adjust the length of lawn trimming.

[0050] As Figure 4 shown, a worm gear 311 coaxially fixed with the U-shaped seat 38 is rotatably connected to the long rod 37. A support frame 312 is fixedly installed on the side wall of the long rod 37. A worm 313 meshing with the worm gear 311 and a first gear 314 coaxially fixed with the worm 313 are rotatably connected to the support frame 312.

[0051] Among them, the worm 313 and the worm gear 311 have a self-locking function for the U-shaped seat 38.

[0052] As Figure 3 and Figure 4 shown, two bent rods 315 distributed up and down are fixedly connected to the surface of the bearing plate 31. A first arc-shaped rack 316 is fixedly connected to one of the bent rods 315 located below, and a second arc-shaped rack 317 is fixedly connected to one of the bent rods 315 located above.

[0053] Among them, the first gear 314 can mesh with the first arc-shaped rack 316 and the second arc-shaped rack 317;

[0054] Among them, the tooth grooves of the first arc-shaped rack 316 are located on the side close to the bearing plate 31, and the tooth grooves of the second arc-shaped rack 317 are located on the side far from the bearing plate 31.

[0055] As Figure 5 and Figure 6 shown, a rake mechanism is arranged above the base 1. The rake mechanism includes two cross bars 41 inserted and telescoped on the side wall of the bearing plate 31 and distributed up and down. A vertical rod 42 is fixedly connected between the two cross bars 41. A rake 43 located above the base 1 is rotatably connected to the vertical rod 42.

[0056] As Figure 5 and Figure 6 shown, a support seat 44 is fixedly connected to the surface of the bearing plate 31. A second gear 45 and a driving rod 46 coaxially fixed with the second gear 45 are rotatably connected to the support seat 44. The free end of the driving rod 46 is rotatably connected to the rake 43. A third gear 47 meshing with the second gear 45 is rotatably connected to the surface of the bearing plate 31.

[0057] Among them, the third gear 47 is driven by an external motor;

[0058] With the above solution, when the staff member pulls the base 1 and walks slowly, the staff member should be walking backwards at this time. The rake 43 can rake the grass cut on the ground or some sundries such as dead branches and fallen leaves to a preset position for subsequent processing.

[0059] When the rectangular rod 36, the long rod 37 and the U-shaped seat 38 rotate clockwise from the vertical state as Figure 1 and Figure 2 shown, the first gear 314 will gradually mesh with the first arc-shaped rack 316, so that the first gear 314 can drive the worm 313 coaxially fixed with it to rotate accordingly. The worm 313 can drive the worm wheel 311 meshing with it to rotate accordingly. The worm wheel 311 can drive the U-shaped seat 38 coaxially fixed with it to rotate by ninety degrees, so that the U-shaped seat 38 and the long rod 37 are in a vertical state, as Figure 7 shown. At this time, the blade 2 rotates, and the side of the green belt can be trimmed.

[0060] When the inclination angles of the long rod 37 and the rectangular rod 36 are different, the height of the blade 2 will be different;

[0061] At the same time, the height of the blade 2 is also related to the lengths of the rectangular rod 36 and the long rod 37. When the rectangular rod 36 and the long rod 37 tilt upward, the longer the length, the higher the position of the blade 2;

[0062] An adjusting component for driving the long rod 37 to extend outwards is arranged in the rectangular rod 36.

[0063] As Figure 7 and Figure 8 shown, the adjusting component includes a first bevel gear 51 rotatably connected in the rectangular rod 36 and coaxially fixed with the sliding column 310. A vertical plate 52 is fixedly connected in the rectangular rod 36. A second bevel gear 53 meshing with the first bevel gear 51 is rotatably connected to the vertical plate 52, and a reciprocating threaded rod 54 coaxially fixed with the second bevel gear 53. A movable sleeve 55 is sleeved on the reciprocating threaded rod 54. A slider adapted to the groove on the surface of the reciprocating threaded rod 54 is rotatably connected to the inner wall of the movable sleeve 55. A cylindrical rod 56 is fixedly connected between the movable sleeve 55 and the long rod 37.

[0064] As Figure 9 、 Figure 10 and Figure 11 shown, an arc-shaped clamping plate 57 is fixed on the sliding column 310. A limiting block 58 coaxially fixed with the second gear 45 is rotatably connected to the support seat 44. A clamping groove adapted to the arc-shaped clamping plate 57 is formed on the surface of the limiting block 58.

[0065] When the sliding column 310 moves along the semi-circular movable groove 34, the arc-shaped clamping plate 57 on the sliding column 310 can be clamped within the limiting block 58. When the second gear 45 rotates, it can drive the arc-shaped clamping plate 57 and the sliding column 310 to rotate accordingly through the limiting block 58, and the sliding column 310 can drive the first bevel gear 51 to rotate accordingly.

[0066] Among them, only when it is necessary to adjust the lengths of the rectangular rod 36 and the long rod 37, the arc-shaped clamping plate 57 on the sliding column 310 can be clamped within the limiting block 58;

[0067] Or when the required height of the blade 2 causes the rectangular rod 36 and the long rod 37 to be in a horizontal state, the arc-shaped clamping plate 57 on the sliding column 310 is clamped within the limiting block 58, but when the blade 2 is working, the limiting block 58 can not rotate.

[0068] Among them, the blade 2 can be Figure 1 the circle in Figure 12 or the strip in

[0069] When it is necessary to trim the lawn with the blade 2 or trim the side of the green belt, the circular blade 2 is adopted;

[0070] When it is necessary to trim the top of the green belt, the strip-shaped blade 2 is adopted;

[0071] Both the circular blade 2 and the strip-shaped blade 2 are detachably installed on the U-shaped seat 38 for easy replacement.

[0072] The working principle and usage process of the present invention:

[0073] The external motor drives the strip-shaped frame 39 to rotate. As the strip-shaped frame 39 rotates, it can push the sliding column 310 to move within the first vertical groove 32, the semi-circular movable groove 34, and the second vertical groove 33;

[0074] When the sliding column 310 is located at the connection of the semi-circular movable groove 34 and the first vertical groove 32, the rectangular rod 36 and the long rod 37 are in a vertical state. At this time, the blade 2 is close to the ground and parallel to the ground. When the blade 2 rotates, it can trim the lawn, and at the same time, the staff needs to push the base 1 to move on the lawn;

[0075] When the sliding column 310 moves up and down within the first vertical groove 32, it can drive the rectangular rod 36, the long rod 37, the U-shaped seat 38, and the blade 2 to move upward accordingly, adjusting the distance between the blade 2 and the ground, thereby adjusting the trimming length of the lawn;

[0076] When the rectangular rod 36, the long rod 37, and the U-shaped seat 38 are from as Figure 1 and Figure 2When rotating clockwise in the vertical state shown, the first gear 314 will gradually mesh with the first arc-shaped rack 316, enabling the first gear 314 to drive the worm 313 fixedly coaxial with it to rotate accordingly. The worm 313 can drive the worm wheel 311 meshing with it to rotate accordingly. The worm wheel 311 can drive the U-shaped seat 38 fixedly coaxial with it to rotate by ninety degrees, so that the U-shaped seat 38 and the long rod 37 are in a perpendicular state, as Figure 7 shown. At this time, when the blade 2 rotates, it can trim the side of the green belt. Similarly, the staff needs to push the base 1 to move;

[0077] When the inclination angles of the long rod 37 and the rectangular rod 36 are different, the height where the blade 2 is located will be different;

[0078] At the same time, the height where the blade 2 is located is also related to the total length of the rectangular rod 36 and the long rod 37. When the rectangular rod 36 and the long rod 37 tilt upward, the more the long rod 37 extends, the higher the position of the blade 2;

[0079] When the sliding column 310 moves along the semi-circular movable groove 34, the arc-shaped clamping plate 57 on the sliding column 310 can be stuck in the limiting block 58. When the second gear 45 rotates, it can drive the arc-shaped clamping plate 57 and the sliding column 310 to rotate accordingly through the limiting block 58. The sliding column 310 can drive the first bevel gear 51 to rotate accordingly. The first bevel gear 51 can drive the second bevel gear 53 meshing with it to rotate accordingly. The second bevel gear 53 can drive the reciprocating threaded rod 54 to rotate accordingly. The reciprocating threaded rod 54 can drive the movable sleeve 55 to move along the rectangular rod 36. The movable sleeve 55 can drive the long rod 37 to move accordingly through the cylindrical rod 56, so that the long rod 37 extends outward from the rectangular rod 36, increasing the working range of the blade 2;

[0080] When the rectangular rod 36, the long rod 37 and the U-shaped seat 38 continue to rotate clockwise from the vertical state as Figure 7 shown, then the first gear 314 will gradually mesh with the second arc-shaped rack 317, enabling the first gear 314 to drive the worm 313 to rotate accordingly. The worm 313 drives the worm wheel 311 to rotate. The worm wheel 311 can drive the U-shaped seat 38 fixedly coaxial with it to rotate by ninety degrees, making the U-shaped seat 38 and the long rod 37 in a straight line, as Figure 12 and Figure 13 shown. At this time, the circular blade 2 can be replaced with a strip-shaped blade 2 to facilitate trimming the top of the green belt;

[0081] When the sliding column 310 moves up and down in the vertical groove two 33, it can drive the rectangular rod 36, the long rod 37, the U-shaped seat 38 and the blade 2 to move upward together, adjusting the overall height of the blade 2 to adapt to green belts of different heights;

[0082] After the lawn mowing is completed, the external motor drives the rotation of the third gear 47. The third gear 47 can drive the second gear 45 meshing with it to rotate accordingly. The second gear 45 can drive the driving rod 46 to rotate accordingly. When the driving rod 46 rotates, it can drive the rake 43 to swing, so that the rake 43 can not only swing up and down with the hinge point between it and the vertical rod 42 as the center of the circle, but also enable the vertical rod 42 to have a horizontal movement, so that the movement track of the end of the vertical rod 42 is circular, and the weeds and other sundries on the ground are raked away.

[0083] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent in such process, method, article or device.

[0084] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
