[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] Embodiment 1:

[0038] Refer to Figure 1-2 , a maintenance device for municipal garden greening construction, which is installed on a mobile trolley. The mobile trolley is a prior art and is used to carry the maintenance device to facilitate the trimming and maintenance of the roadside green belt. It includes a fixed frame 1 and a trimming frame 2. The fixed frame 1 is equipped with components for driving the movement of the trimming frame 2, and the trimming frame 2 is equipped with components for trimming and collecting the green belt.

[0039] Refer to Figure 1 , the fixed frame 1 is fixedly installed on the mobile trolley by bolts. A lead screw 12 is rotatably arranged in the fixed frame 1. A first slider 11 is arranged on the surface of the lead screw 12 in a threaded manner. At the same time, the first slider 11 slides on the surface of the fixed frame 1. Two limit shafts 14 symmetrically arranged on both sides of the lead screw 12 are fixed to the fixed frame 1, and the limit shafts 14 penetrate through the first slider 11 for sliding fit to ensure the stability of the first slider 11 during the lifting movement. A first motor 13 is fixedly arranged on the upper end surface of the fixed frame 1. The output shaft of the first motor 13 is fixed to the upper end of the lead screw 12. By driving the rotation of the lead screw 12 by the first motor 13, the first slider 11 is driven to perform a lifting movement.

[0040] Refer to Figure 1, on the outer side of the first slider 11, a U-shaped support block 15 is fixedly installed by bolts. Inside the U-shaped support block 15, a sliding shaft 151 is fixedly arranged. On the surface of the sliding shaft 151, a second slider 16 is slidably arranged. Telescopic cylinders 17 are fixedly installed on the outer side of the second slider 16 and the lower outer side of the U-shaped support block 15.

[0041] Reference Figure 1 , and on the upper and lower positions of the second slider 16, a first spring 152 sleeved on the surface of the sliding shaft 151 is arranged. The two ends of the first spring 152 are respectively fixed to the second slider 16 and the U-shaped support block 15.

[0042] Reference Figure 1 , on the upper surface and the left side surface of the trimming frame 2, connecting seats 21 are fixedly installed. On the outer end of the piston rod of the telescopic cylinder 17, a connecting block 171 is fixedly installed. The connecting block 171 is hinged with the connecting seat 21.

[0043] Specifically, when it is necessary to trim the side of the green belt, drive the upper telescopic cylinder 17 so that the upper connecting block 171 and the lower connecting block 171 are on the same vertical plane. At this time, the trimming frame 2 rotates 90 degrees and is perpendicular to the ground, and its trimming surface faces the side of the green belt. And the second slider 16 will slide up on the surface of the sliding shaft 151. The upper first spring 152 is compressed, and the lower first spring 152 is stretched. After trimming the side of the green belt, the deformation of the first spring 152 can assist the second slider 16 to return to its original position again, making the trimming frame 2 horizontal to the ground.

[0044] If the side of the green belt has an inclination, it is also possible to drive the upper telescopic cylinder 17 to drive the trimming surface of the trimming frame 2 to be parallel to the side of the green belt, and then trim the green belt through the trimming frame 2.

[0045] Reference Figure 2-4 , inside the trimming frame 2, a rotating shaft 7, a shredded leaf placement frame 6 and a dust collection frame 24 are arranged in sequence from left to right. The rotating shaft 7 is rotatably matched with the trimming frame 2. On the outer side surface of the trimming frame 2, a second motor 22 is fixedly arranged. The output shaft of the second motor 22 is fixed to the rotating shaft 7. The rotating shaft 7 is driven to rotate by the second motor 22.

[0046] Reference Figure 2-4 , on the surface of the rotating shaft 7, a number of trimming knives 71 are fixedly installed by bolts. The trimming knife 71 is composed of a circular ring and a number of blades, which can trim the green belt to be trimmed entering the trimming frame 2. And the rotation angles of every two trimming knives 71 are different, which is convenient for the shredded leaves after trimming to enter the shredded leaf placement frame 6.

[0047] Reference Figure 2-6, at the left - end feed - inlet position of the trimming frame 2, a carding member 8 is fixedly installed by bolts. The carding member 8 is provided with a number of carding teeth 84. The green belt is evenly divided by the carding teeth 84, and then trimmed by the trimming knife 71. And between every two carding teeth 84, a sliding rod 81 is provided. On the outer side of the trimming frame 2 corresponding to the sliding rod 81, a first chute 214 is opened. The sliding rod 81 passes through the carding member 8 and slides in the first chute 214. And between the sliding rod 81 and the inner bottom surface of the first chute 214, a third spring 83 is fixedly connected. On the outer end surface of the sliding rod 81, a push - plate 82 is fixedly provided. The push - plate 82 slides between the two carding teeth 84.

[0048] Specifically, when the carding teeth 84 card and divide the green belt, the green belt will squeeze the push - plate 82 into the first chute 214, and the third spring 83 is compressed. When the trimming is completed, through the rebound of the third spring 83, the sliding rod 81 and the push - plate 82 are driven to return to their original positions, and then the residual leaves of the green belt between the carding teeth 84 are cleaned, facilitating the next use of the carding teeth 84.

[0049] Reference Figure 2 , on the right - hand side of the trimming frame 2, a flip - type sealing plate 23 is provided. The sealing plate 23 is hinged to the trimming frame 2 through a hinge 231. At the corresponding positions on the outer sides of the sealing plate 23 and the trimming frame 2, ear plates 232 are welded. The two ear plates 232 are fixedly connected by bolts.

[0050] Specifically, opening the sealing plate 23 facilitates taking out the shredded - leaf placement frame 6 and the dust collection frame 24.

[0051] Reference Figure 3 、 Figure 7-9 , inside the trimming frame 2, a connecting frame 5 is fixedly provided.

The outer sides of the two filter plates 51 are respectively fixed on the left and right inner walls of the trimming frame 2, facilitating the separation of shredded leaves and dust, and ensuring that the shredded leaves enter the shredded - leaf placement frame 6.

[0052] Figure 7-9 , symmetrically on the outer side of the connecting frame 5, a first T - shaped groove 511 is opened. One end of the groove 511 communicates with the outside, and the other end does not communicate with the outside.

[0053] Symmetrically on the outer side of the shredded - leaf placement frame 6, first T - shaped blocks 62 are fixedly provided. The blocks 62 slide in the groove 511.

[0054] Figure 7-9, a groove two 611 is formed on the surface of the outer circle position on the left side of the broken leaf placement frame 6. A T-shaped block two 63 is slidably arranged in the groove two 611. A spring two 631 is symmetrically and fixedly connected between the block two 63 and the groove two 611. One end of the block two 63 penetrates through the groove two 611 and can expose the position with a circular hole it carries to the outside.

[0055] By pulling the block two 63 in the outside world, the block two 63 can slide and expand in the groove two 611.

[0056] Figure 7-9 , a groove one 511 is formed at the position corresponding to the block two 63 on the outer side surface of the connection frame 5. The block two 63 is in sliding fit with the groove two 611.

[0057] Specifically, when the broken leaf placement frame 6 and the connection frame 5 are connected together through the block one 62 and the chute two 52, by pulling the block two 63 to make the block two 63 enter the groove two 611, the broken leaf placement frame 6 and the connection frame 5 can be fixed together, avoiding the shaking of the broken leaf placement frame 6 in the trimming frame 2 during the trimming process.

[0058] Figure 7 , a filter plate one 51 is fixedly arranged on the right side surface of the broken leaf placement frame 6, which is convenient for further separating the dust in the broken leaves.

[0059] Figure 4 , a guide plate one 25 and a guide plate two 251 fixed to the trimming frame 2 are arranged on the right side of the broken leaf placement frame 6. The dust collection frame 24 is slidably arranged between the guide plate one 25 and the guide plate two 251. Both the guide plate one 25 and the guide plate two 251 are inclined, which is convenient for guiding the dust into the dust collection frame 24. And electric telescopic rods 252 fixed on the inner surface of the trimming frame 2 are symmetrically arranged in the space surrounded by the guide plate two 251 and the trimming frame 2. The piston rod of the electric telescopic rod 252 penetrates through the upper surface of the guide plate two 251 and is in sliding fit. And a scraper 253 parallel to the inclined surface of the guide plate two 251 is fixedly arranged at the upper end of the piston rod of the electric telescopic rod 252.

[0060] Figure 4 , an air extraction frame 3 is fixedly installed on the right side surface of the trimming frame 2. The air extraction frame 3 is communicated with the inside of the trimming frame 2. And an air extraction pipe 31 is communicated with the outside of the air extraction frame 3. The air extraction pipe 31 is connected to an external air extraction pump. The air extraction pump can be fixed on a mobile trolley, and the air extraction pump is prior art and does not need to be described and drawn in detail here.

[0061] Figure 3-4, a dust-proof net 32 is fixedly arranged on the outer side surface of the air extraction frame 3. The scraper 253 slides on the surface of the dust-proof net 32. By driving the lifting of the scraper 253 through the electric telescopic rod 252, the dust attached to the surface of the dust-proof net 32 can be cleaned, and it falls into the dust collection frame 24 along the scraper 253.

[0062] Figure 4 , an inclined plate 211 is fixedly arranged on the left side of the trimming frame 2. An air intake frame 212 is fixedly arranged on the surface of the inclined plate 211. The air intake frame 212 is communicated with the inside of the trimming frame 2, and an air inlet pipe 213 is communicated with the outside of the air intake frame 212. The air inlet pipe 213 is connected to an external air intake pump. The air intake pump can be fixed on a mobile trolley, and the air intake pump is prior art and will not be described and drawn in detail here.

[0063] Specifically, during the process of trimming the green belt, the external air intake pump will blow the gas through the air intake frame 212 to blow the shredded leaves and generated dust trimmed by the trimming knife 71, and at the same time, the external air extraction pump will extract the shredded leaves and generated dust. The two cooperate to effectively separate the shredded leaves and dust, so that the shredded leaves enter the shredded leaf placement frame 6, and the dust is adsorbed on the dust-proof net 32. After trimming, the dust on the surface of the dust-proof net 32 is scraped into the dust collection frame 24 by the scraper 253. Then, the sealing plate 23 is opened, and the shredded leaf placement frame 6 and the dust collection frame 24 are taken out, and then subsequent processing is carried out. This method can greatly reduce the splashing of dust during the trimming process and can reasonably collect and process the trimmed shredded leaves.

[0064] Embodiment 2:

[0065] Figure 2-4 , on the basis of Embodiment 1, in order to further perform dust-proof treatment on the position below the trimming part of the green belt, a stop rod 4 can be fixedly arranged on the lower end surface of the trimming frame 2.

[0066] Figure 2-4 , the stop rod 4 has an inclined surface, which is convenient for the trimming frame 2 to move and can easily pass above the green belt without forming an obstacle. A water storage tank 43 is arranged in the stop rod 4, and water inlet pipes 41 communicated with the water storage tank 43 are fixedly installed on both sides of the stop rod 4. Through the water inlet pipes 41, the external water flow can be introduced into the water storage tank 43. A plurality of atomizing nozzles 42 communicated with the water storage tank 43 are fixedly arranged on the right side surface of the stop rod 4. Through the cooperation of an external pressurizing device and a water conveying device, the water flow in the water storage tank 43 is sprayed onto the surface of the trimmed green belt through the atomizing nozzles 42.

[0067] Specifically, by spraying water on the pruned green belt through the atomizing nozzle 42, it is possible to effectively reduce the phenomenon of dust splashing in the green belt during the pruning process, and can clean the leaves of the green belt, helping the plants to better carry out photosynthesis, promoting healthy growth, and increasing the ornamental value at the same time.
