Description

Technical Field

[0001] The present application relates to the field of greening maintenance, and in particular to an urban greening maintenance device. Background Art

[0002] Outdoor playgrounds such as park scenic spots in the city generally have lawns laid for tourists to play on, and the lawns need to be maintained regularly. The main maintenance work includes mowing, watering, fertilizing, and punching, etc. Among them, watering and fertilizing can be carried out through the sprinkler irrigation system, while mowing and punching need to be carried out regularly as required by personnel using corresponding equipment.

[0003] Existing mowing equipment generally sets a high-speed rotating blade under a vehicle body that can be pushed, so as to mow the overgrown lawn during the forward movement of the vehicle body. For example, a landscaping maintenance device with the publication number CN220191482U.

[0004] In view of the above related technologies, when watering has just been completed or water has been poured on some lawns, since the grass leaves are contaminated with a certain amount of water droplets at this time, the grass leaves are relatively soft and sticky, and it is difficult to mow the lawn neatly and effectively at this time, and the blade is also easily contaminated with grass leaves, making the mowing work difficult to proceed smoothly. Summary of the Invention

[0005] In order to smoothly carry out the mowing work even when the grass leaves are slightly wet, the present application provides an urban greening maintenance device.

[0006] The urban greening maintenance device provided by the present application adopts the following technical solutions.

[0007] An urban greening maintenance device includes a movable vehicle body and a blade provided on the vehicle body for cutting grass leaves. A middle seat is detachably connected to the front end of the vehicle body. The middle seat is rotatably connected to a front cylinder whose rotation axis direction is consistent with the axis direction of the vehicle wheels of the vehicle body. The middle seat is provided with a front cylinder motor for driving the front cylinder to rotate. A plurality of water-absorbing water-removing members are fixedly connected to the circumferential surface of the front cylinder. The rotation direction of the bottom of the front cylinder faces the front when the vehicle body moves. A hot air blower capable of sending hot air to the lawn is detachably connected to the middle seat, and the air outlet of the hot air blower is located between the front cylinder and the vehicle body.

[0008] By adopting the above technical solutions, when the grassland is slightly wet, the middle seat and the vehicle body are connected and fixed. During the process of the vehicle body moving forward for mowing, the water-removing members will first rotate along with the front cylinder to pat the water droplets on the grass leaves towards the front when the vehicle body moves, so that the grass leaves passing through the water-removing members are not easily contaminated with the water droplets patted off by the water-removing members. Then, the hot air blower generates hot air to remove the residual moisture on the surface of the grass leaves, so that the grass leaves are not easily adhered to each other, and not too much grass leaves are easily adhered to the blade during mowing, so as to smoothly carry out the mowing operation.

[0009] Optionally, the water removal member can elastically deform. The middle seat is rotatably connected with a water squeezing cylinder that can be close to the side of the front cylinder near the vehicle body and can squeeze the water removal member. The middle seat is detachably connected with a water receiving channel located directly below between the front cylinder and the water squeezing cylinder. The water receiving channel is inclined, and the middle seat is detachably connected with a water receiving tank located at one end of the lowest point of the water receiving channel.

[0010] By adopting the above technical solution, each time the water squeezing member rotates, it will pass through the water squeezing cylinder, so that the water adsorbed by the water squeezing member can be timely squeezed into the water receiving tank, so that the water removal member can effectively suck a relatively large amount of water existing on the grass leaves.

[0011] Optionally, the middle seat is detachably connected with a water baffle that can fit on the highest point of the water squeezing cylinder.

[0012] By adopting the above technical solution, it further reduces the situation that the water removal member brings the water on the grass leaves back to the grass leaves whose surface water is being removed by the hot air flow, and improves the drying degree of the grass leaves during mowing.

[0013] Optionally, the water removal members are densely distributed on the front cylinder and are in the shape of a cylinder and made of sponge. The middle seat is detachably connected with a baffle located on the side of the front cylinder away from the vehicle body. The bottom of the baffle is fixedly connected with a front piece column that can contact one end of the water removal member close to the front cylinder, and the water removal member can pass between two adjacent front piece columns.

[0014] By adopting the above technical solution, it reduces the damage to the lawn caused by the water removal member when patting the grass leaves. At the same time, the front piece column can also remove some fallen grass leaves contaminated by the water removal member, so as to reduce the frequency of cleaning and maintaining the inside of the middle seat.

[0015] Optionally, the middle seat is rotatably connected with an air cylinder. The middle seat is provided with an air cylinder motor for driving the air cylinder to rotate. The inside of the air cylinder is communicated with the air outlet of the electric hot air blower, and the circumferential surface of the air cylinder is provided with air ports for sending out hot air flow.

[0016] By adopting the above technical solution, the rotating air cylinder makes the air ports for sending out the hot air flow rotate, so that the direction of the hot air flow is also constantly changing, so as to more comprehensively remove the residual water on the surface of the grass leaves.

[0017] Optionally, the axis direction of the air cylinder is vertical. The air cylinders are arranged in several rows along the advancing direction of the vehicle body and there are several in each row. The air ports include upper inclined ports and lower inclined ports. The upper inclined ports are located at the upper part of the air cylinder and send out hot air downward to the upper surface of the grass leaves, and the lower inclined ports are located at the lower part of the air cylinder and send out hot air upward to the lower surface of the grass leaves.

[0018] By adopting the above technical solution, it reduces the situation that most of the grass leaves are pressed down during the forward movement of the air cylinder, which is not conducive to subsequent mowing. At the same time, the setting of the upper inclined ports and the lower inclined ports also enables the water on the upper surface and the lower surface of the grass leaves to be fully removed.

[0019] Optionally, the middle seat is detachably connected to a front seat at one end away from the vehicle body, the front seat is transmission-connected to a collecting belt, a plurality of collecting blocks are fixedly connected to the surface of the collecting belt, the collecting blocks can move close to the inner wall of the front seat, and the front seat is detachably connected to a collecting box at the end where the collecting belt is higher, for objects driven by the collecting blocks to enter.

[0020] By adopting the above technical solution, some stones on the lawn or small objects dropped by tourists can be collected, reducing the possibility of damage to the blades. The lawn can also be cleaned while mowing the lawn, reducing the possibility of harm to tourists due to stones and debris on the lawn.

[0021] Optionally, the collecting block includes a fixed block fixedly connected to the collecting belt, a movable block slidably connected to the fixed block and unable to be separated from the fixed block, and a compression spring located between the fixed block and the movable block and forcing the movable block to be separated from the fixed block.

[0022] By adopting the above technical solution, it is ensured that when the moving block contacts objects such as stones, the collecting belt is not easily subjected to excessive pressure, thereby reducing the possibility of damage to the collecting belt.

[0023] Optionally, a wall groove is provided in the front seat for the collection box to enter the opening side close to the collection belt, and a drop opening connected to the wall groove is provided in the front seat. The closer the drop opening is to one end of the collection belt, the higher its height is. The end with the higher height of the drop opening is located on the surface in the front seat for the upward collection block to move over.

[0024] By adopting the above technical solution, the collection box is placed in the wall groove, so that when the collection block drives the stones and debris to fall into the collection box, it is not easy for the stones and debris to fall out of the collection box.

[0025] Optionally, the front seat can be detachably connected to the vehicle body.

[0026] By adopting the above technical solution, when the lawn is not wet, the front seat and the vehicle body can be directly connected without the need to synchronously set the middle seat.

[0027] In summary, the present application includes at least the following beneficial effects.

[0028] When the grass is somewhat damp, the middle seat and the vehicle body are connected and fixed, so that when the vehicle body moves forward to mow the grass, the water removal component will first rotate with the front cylinder to knock the water droplets on the grass leaves to the front of the vehicle body when it moves, so that the grass leaves passing through the water removal component are not easily contaminated by the water droplets knocked off by the water removal component. Then the electric blower generates hot air to remove the residual moisture on the surface of the grass leaves, so that the grass leaves are not easy to stick to each other, and too many grass leaves are not easy to adhere to the blade when mowing, so that the mowing operation can be carried out smoothly.

Detailed implementation manners

[0031] The following further elaborates on this application with reference to the accompanying drawings.

[0032] An embodiment of this application discloses a city greening maintenance device. Referring to Figure 1 , it includes a vehicle body 1 that can be pushed forward. A blade 2 for cutting grass leaves is rotatably connected to the bottom surface of the vehicle body 1. The vehicle body 1 is provided with a gasoline generator and is equipped with a motor to drive the blade 2 to rotate.

[0033] Referring to Figure 1 and Figure 2 , a middle seat 3 can be detachably connected to the front end of the vehicle body 1 during movement. A front seat 44 is detachably connected to the side of the middle seat 3 away from the vehicle body 1. The front seat 44 is drivingly connected to an inclined collecting belt 45. During the process of the collecting belt 45 moving forward with the vehicle body 1, the lower end of the collecting belt 45 is the front end, and the width direction of the collecting belt 45 is horizontal and perpendicular to the moving direction of the vehicle body 1. A belt pulley and a motor are arranged in the front seat 44 to drive the collecting belt 45 to transmit. A plurality of collecting blocks 46 are evenly fixedly connected to the transmission surface of the collecting belt 45. The collecting blocks 46 located at the bottom end of the collecting belt 45 move from front to back, so that stones, sundries, etc. can be driven by the collecting blocks 46 to move upward along the inclined inner wall of the front seat 44.

[0034] Referring to Figure 2The upper part of the front seat 44 is formed with an opening, and a collection box 47 is vertically placed in the upper opening of the front seat 44. A wall groove 32 is provided on the inner wall of the front seat 44 close to the collection belt 45, and a part of the collection box 47 can enter the wall groove 32 along the forward movement direction of the vehicle body 1. A rubber strip can be provided in the wall groove 32 so that the collection box 47 can be tightly embedded in the wall groove 32. In addition, an inclined drop opening 35 is provided on the vertical inner wall of the wall groove 32 close to the collection belt 45, and the upper end of the drop opening 35 is connected to the space where the collection belt 45 is provided in the front seat 44, so that the stones and debris driven by the collection block 46 to move can fall into the collection box 47 along the drop opening 35 when passing through the drop opening 35. In addition, the middle seat 3 can be disassembled to connect the front seat 44 and the vehicle body 1.

[0035] Reference Figure 2 The collecting block 46 includes a fixed block 48 fixedly connected to the collecting belt 45. The fixed block 48 is inserted and slidably connected with a moving block 49 in a direction perpendicular to the conveying surface of the collecting belt 45. The moving block 49 is located in the fixed block 48 and has a larger width at one end, so that the moving block 49 is difficult to separate from the fixed block 48. A compression spring 31 is placed in the moving block 49. The compression spring 31 forces the moving block 49 to stay away from the fixed block 48, so that when the moving block 49 contacts stones and debris, the collecting belt 45 is not easily subjected to excessive pressure.

[0036] Reference Figure 1 and Figure 2 , the middle seat 3 is rotatably connected to the front cylinder 4 at one side near the front seat 44, the rotation axis direction of the front cylinder 4 is horizontal and perpendicular to the forward movement direction of the vehicle body 1, and the middle seat 3 is detachably connected to the front cylinder motor 34 whose output shaft is coaxially detachably connected to the front cylinder 4. The circumferential surface of the front cylinder 4 is fixedly connected with a water removal member 5, which is densely distributed on the front cylinder 4 and is cylindrical and made of sponge, so that the water removal member 5 can knock off the water drops on the grass leaves during the rotation of the front cylinder 4. In addition, the bottom of the front cylinder 4 rotates in the direction toward the front of the vehicle body 1, so that the water removal member 5 brings the water drops forward. The middle seat 3 is rotatably connected to a water squeezing cylinder 53 whose axis direction is consistent with the axis direction of the front cylinder 4, and the water squeezing cylinder 53 is close to the middle and lower part of the front cylinder 4 on the side close to the vehicle body 1, so that the water removal member 5 will be squeezed and deformed between the water squeezing cylinder 53 and the front cylinder 4, so that the water adsorbed by the water removal member 5 can be squeezed out. The middle seat 3 is detachably connected with a water receiving channel 52 located just below the space between the water squeezing cylinder 53 and the front cylinder 4. The water receiving channel 52 is slightly inclined. The lower end of the water receiving channel 52 is connected with a water receiving box 54. The water receiving box 54 is detachably connected to the middle seat 3. A valve can be set at the bottom of the water receiving box 54 to release the collected water after the mowing work is completed. In addition, the middle seat 3 is detachably connected with a water baffle 43 attached to the highest point of the water squeezing cylinder 53, so that when the water removing part 5 rotates downward to approach the water squeezing cylinder 53, the water removing part 5 is not easy to throw water to the middle seat 3 located behind the front cylinder 4.

[0037] ReferenceFigure 2 , a baffle 55 is detachably connected to one side of the middle seat 3 away from the vehicle body 1. The baffle 55 is inclined, and the bottom end of the baffle 55 is farther away from the vehicle body 1 than the upper end of the baffle 55. The baffle 55 is located at a position on the side of the front cylinder 4 away from the water squeezing cylinder 53. A plurality of front column pieces 56 are uniformly and fixedly connected to the bottom end of the baffle 55 along the axial direction of the front cylinder 4. The bottom ends of the front column pieces 56 are close to the circumferential surface of the front cylinder 4. When the water removing member 5 passes between two adjacent front column pieces 56, the front column pieces 56 will block the grass leaves contaminated on the water removing member 5, reducing the possibility of the grass leaves entering the middle seat 3 along with the water removing member 5.

[0038] Refer to Figure 2 and Figure 3 , an electric hot air blower 51 is detachably connected to the middle seat 3. The air outlet of the electric hot air blower 51 is communicated with several rows of air cylinders 57, each row having several air cylinders 57. The air cylinders 57 are rotatably connected to the middle seat 3 and the rotation axis is vertical. The middle seat 3 is detachably connected with an air cylinder motor 59 for driving the air cylinders 57 to rotate. The air cylinder motor 59 can be set corresponding to each air cylinder 57, or one or a small number of air cylinder motors 59 can be used and matched with synchronous pulleys and synchronous belts for synchronous rotation. Several air ports 58 for sending out hot air flow are arranged on the circumferential surface of the air cylinder. The air ports 58 of each air cylinder 57 include an upper inclined port 41 and a lower inclined port 42. The upper inclined port 41 is located in the upper middle part of the air cylinder 57 and is inclined downward, and the lower inclined port 42 is located in the lower middle part of the air cylinder 57 and is inclined upward, so as to remove the moisture on the upper surface and the lower surface of the grass leaves more comprehensively.

[0039] The implementation principle of a city greening maintenance equipment according to an embodiment of the present application is as follows: When mowing the grass, the front seat 44 first passes through the corresponding position of the lawn, so that the stones, sundries, etc. on the lawn can be driven by the collection block 46 into the collection box 47. Then the middle seat 3 passes through the corresponding position of the lawn, so that the water removing member 5 can first pat off a relatively large amount of water on the grass leaves. Then the air cylinders 57 perform a more comprehensive moisture removal on the grass leaves with most of the water patted off. Then the vehicle body 1 passes through the corresponding position of the relatively dry lawn so that the blade 2 performs the mowing work.

[0040] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
