Description

Technical Field

[0001] This invention relates to a maintenance device, and more specifically, to a lawn maintenance device with a sieving function. Background Technology

[0002] As an indispensable component of urban ecology and landscape construction, green lawns not only serve the practical functions of beautifying the environment and purifying the air, but also profoundly influence people's quality of life and mental health. Based on their different uses and functional characteristics, green lawns can be subdivided into two main categories: sports lawns and ornamental lawns. Each type has its own unique charm and strengths.

[0003] Regular lawn maintenance is essential to ensure optimal condition and maximize the benefits of green lawns. Lawn maintenance is a systematic and meticulous process, with mulching and aeration being two key techniques that play an irreplaceable role in maintaining lawn health and enhancing the landscape. Mulching, which involves evenly covering the lawn surface with a layer of fine sand or a professional lawn mulch, is a crucial step in lawn maintenance. Aeration, which uses specialized equipment to create small holes in the lawn, is an effective way to improve the soil environment and promote healthy lawn growth.

[0004] Our company previously applied for a fine-grained maintenance device for exposed lawn roots, publication number CN110214637A, which can perform sand covering and aeration operations on lawns. During use, this device uses a sand-removing roller to remove sand, but this method results in uneven sand distribution, affecting the sand covering effect. Furthermore, the existing equipment lacks a screening function, making it unable to flexibly adapt the sand covering operation to different ground conditions. Summary of the Invention

The punching mechanism is provided in multiple sets, all of which are arranged at equal intervals along the width direction of the vehicle body; The pushing mechanism includes a pushing plate and a guide structure. Multiple sets of guide structures are arranged at equal intervals along the length of the pushing plate, and each guide structure corresponds one-to-one with a drilling mechanism.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 8 As shown, to achieve the above objectives, the present invention provides the following technical solution: a lawn maintenance device with sieving function, comprising a vehicle body 1, a sand storage box 2, a sand covering mechanism 3, a leveling mechanism 4, and a perforating mechanism 5. The sand storage box 2 is disposed at the upper end of the vehicle body 1, a sieving mechanism 6 is disposed inside the sand storage box 2, a sand outlet is disposed at the lower end of the sand storage box 2, the sand covering mechanism 3 is disposed at the sand outlet, and the leveling mechanism 4 and the perforating mechanism 5 are respectively disposed on both sides of the sand covering mechanism 3. The screening mechanism 6 includes a screening base 61, a screening disc, and a driving component. The screening base 61 is provided with multiple sand storage chambers 62. The screening disc is rotatably connected to the lower end of the screening base 61. The screening disc is provided with a discharge port. The driving component is used to control the rotation of the screening disc so that the discharge port is aligned with a sand storage chamber 62. Multiple sets of punching mechanisms 5 are provided, all of which are arranged at equal intervals along the width direction of the vehicle body 1; The pushing mechanism 4 includes a pushing plate 41 and a guide structure 42. Multiple sets of guide structures 42 are provided and are arranged at equal intervals along the length of the pushing plate 41. The guide structure 42 is provided in a one-to-one correspondence with the drilling mechanism 5. The guide structure 42 is used to push the gravel into the hole made by the drilling mechanism 5.

[0022] Gravel can be replaced by fine soil or sand.

[0023] The design of this invention has the following advantages compared to prior art: 1. It can perform sand covering operation for multi-component gravel. By storing gravel of different components in different sand storage chambers 62, the discharge port is aligned with the sand storage chamber 62 by rotating the screening disc. At this time, the gravel in the sand storage chamber 62 can fall through the discharge port of the screening disc to the space between the sand storage box 2 and the screening seat 61, and then be discharged from the sand outlet through the sand covering mechanism 3.

[0024] The sand covering mechanism 3 can adopt the structure of the prior application.

[0025] This allows for adjustments to variables such as gravel composition and size based on lawn conditions or other factors.

[0026] 2. The leveling mechanism 4 can spread the poured gravel evenly on the lawn, maintaining the stability of the sand covering effect.

[0027] 3. Drilling holes first and then covering them with sand allows the holes to be filled with gravel, preventing them from closing due to natural settlement or rainwater erosion, thus prolonging the air and water permeability. Furthermore, the guiding structure 42 ensures that the gravel fully fills the holes.

[0028] The present invention is further configured such that: the guide structure 42 includes a guide cavity 43 disposed in the push plate 41, the guide cavity 43 is T-shaped, the lower end of the push plate 41 is provided with an outlet 44 communicating with the guide cavity 43, and the side of the push plate 41 facing the sand covering mechanism 3 is provided with an inlet 45 communicating with the guide cavity 43. During the movement of vehicle body 1, gravel is accumulated in guide cavity 43 by inlet 45.

[0029] A guide slope 46 is provided inside the guide cavity 43. One end of the guide slope 46 is connected to the inlet 45, and the other end is inclined downward toward the outlet 44.

[0030] In this structure, as the vehicle body 1 moves, the pusher plate 41 can gradually flatten the stack of gravel. At this time, the gravel enters the guide cavity 43 through the inlet 45. Since the outlet 44 is blocked by gravel, this part of the gravel is accumulated in the guide cavity 43 until the outlet 44 moves to the drilling position. At this time, this part of the gravel can fall into the hole and effectively fill the hole.

[0031] The present invention is further configured such that: a guide post 47 is slidably connected to the outlet 44, the guide post 47 is configured with a through-hole in the upper and lower parts, and a sealing plate 48 for sealing the outlet 44 is provided in the middle of the guide post 47, and a gap is left between the guide post 47 and the sealing plate 48 for the sand and gravel to slide down. The push plate 41 is equipped with a linkage mechanism 7 for controlling the lifting and lowering of the guide column 47.

[0032] The structure is designed to restrict the outflow of gravel by using a sealing plate 48. When the outlet 44 moves to the opening position, it is opened by the linkage mechanism 7 to ensure the stable transfer of gravel.

[0033] The present invention is further configured such that: the linkage mechanism 7 includes a linkage motor 71, a first sprocket 72, a transmission chain 73 and a transmission rod 74, and multiple sets of the first sprocket 72 and the transmission rod 74 are provided. The transmission rod 74 is fixedly connected to the first sprocket 72, and the guide post 47 is threadedly engaged with the transmission rod 74. The two adjacent first sprockets 72 are linked together by the transmission chain 73; A first sprocket 72 is connected to a linkage motor 71 via a transmission chain 73.

[0034] The design of the linkage mechanism 7, such as Figure 7 and Figure 8 As shown, when the linkage motor 71 starts, the first sprocket 72 rotates, and the transmission rod 74 is connected to the guide post 47 through the screw nut. When the transmission rod 74 rotates, the guide post 47 moves linearly. At this time, the sealing plate 48 opens the outlet 44 position, and the gravel falls from above into the hole.

[0035] Furthermore, under the action of the transmission chain 73, multiple outlets 44 are opened simultaneously, improving work efficiency.

[0036] The present invention is further configured such that: the punching mechanism 5 includes a punching head 51, a punching base 52, a punching motor 53 and a punching cylinder 54, the punching motor 53 is mounted on the punching base 52 and is used to drive the punching head 51 to rotate; The punching cylinder 54 is used to move the punching base 52.

[0037] The present invention is further configured such that: the punching mechanism 5 includes an adjusting sleeve 75 slidably connected to the outside of the punching head 51, the lower end of the adjusting sleeve 75 is hinged (connected by a torsion spring) with multiple sets of adjusting arms 76 along its circumference, and an adjusting block 77 is provided on the outside of the punching head 51. When the adjusting sleeve 75 moves down, the adjusting arm 76 abuts against the adjusting block 77 and thus folds outward. A linkage structure 8 is provided between the adjusting sleeve 75 and the punching seat 52.

[0038] The design of this structure, such as Figure 3 and Figure 4 As shown, when the punching cylinder 54 pushes the punching seat 52 to move (the punching motor 53 starts synchronously), the punching head 51 first contacts the lawn surface to perform an effective punching operation.

[0039] Furthermore, as the punch head 51 moves downward, the adjusting sleeve 75 moves downward relative to the punch head 51. At this time, the adjusting arm 76 abuts against the adjusting block 77 and flips outward. As the adjusting sleeve 75 gradually moves downward, the flipping angle increases, thereby punching an inverted cone-shaped structure in the lawn. The design of the linkage structure 8 allows the outward flipping of the adjusting arm 76 and the downward movement of the punch head 51 to proceed synchronously, ensuring work efficiency.

[0040] In addition, in Embodiment 2, when the linkage structure 8 is not designed, a cylinder structure that drives the adjusting sleeve 75 to move downward can be designed separately through a secondary drive. After the drilling head 51 completes the drilling operation, the adjusting sleeve 75 is driven downward, and the inverted conical structure is pushed out in the hole by extrusion.

[0041] The design of this structure allows for inverted cone-shaped (smaller at the top and larger at the bottom) aeration, which has the following benefits: by optimizing the hole structure, improving the soil environment, and promoting healthy turf growth, it can significantly improve the turf's aeration, drainage, and root development.

[0042] Smaller design: Reducing the diameter of the orifice can decrease surface moisture evaporation while maintaining the air exchange channel between the orifice and the outside.

[0043] Larger structure: Enlarging the bottom diameter of the hole increases the contact area between the soil and the air, promotes oxygen circulation in the deeper soil, provides sufficient oxygen for the roots, and is especially beneficial to the activity of aerobic microorganisms and the decomposition of organic matter.

[0044] Increased space at the bottom of the holes: The larger structure provides more space for root growth, guiding roots to extend into deeper soil layers and enhancing the lawn's drought resistance and trampling resistance.

[0045] Furthermore, in conjunction with the aforementioned linkage mechanism 7, it enables columnar filling operations during gravel filling (the guide column has an H-shaped cross-section), thereby ensuring that there is still a certain space gap on both sides of the bottom of the hole, maintaining the effective extension of the root system. This satisfies a certain filling effect, ensures that the hole is not easily closed, and provides sufficient gaps on both sides inside the hole.

[0046] Note that during the movement of the vehicle, it will be stationary when drilling, at which point the exit position will be exactly opposite the drilled hole.

[0047] The linkage structure 8 can be designed as follows: the drilling mechanism 5 includes a drilling frame 55, a drilling cylinder 54 is fixedly installed on the drilling frame 55, and a drilling seat 52 is slidably connected to the drilling frame 55. The linkage structure 8 includes a linkage chain 81, a second sprocket 82, and a linkage plate 83. The second sprocket 82 is provided in two sets, both of which are installed on the punching base 52. Link chain 81 is used to connect the two second sprockets 82; Two sets of linkage plates 83 are provided and are installed on both sides of the linkage chain 81 respectively. One linkage plate 83 is connected to the adjusting sleeve 75, and the other linkage plate 83 is connected to the punching frame 55.

[0048] When the punch holder 52 slides downward, since a linkage plate 83 is connected to one side of the linkage chain 81 and the punch holder 55 respectively, the linkage plate 83 moves upward in relative position. At this time, the linkage plate 83 on the other side moves downward, thereby causing the adjusting sleeve 75 to move downward as well. During the cylinder drive process, the adjusting sleeve 75 is driven to move together.

[0049] The present invention is further configured such that: the sand covering mechanism 3 includes a sand discharge roller, and a sand discharge groove is provided on the sand discharge roller.

[0050] The sand discharge roller is connected to a sand discharge motor. The sand and gravel in the sand discharge box fall into the sand discharge groove of the sand discharge roller, and during the rotation of the sand discharge roller, they are scattered onto the lawn.

[0051] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
