Description

A type of rolling lawn aerator Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment, and in particular relates to a rolling lawn aerator. Background Technology

[0002] After rain, soil aeration is poor, affecting plant growth. It's necessary to increase soil aeration to avoid damaging plants, and this can be achieved by aerating the soil. Lawn aerators can be categorized into vertical aerators and selective aerators based on the rotation method of their blades. Vertical aerators have fewer blades, resulting in poorer aeration and fewer applications. Rotary aerators, on the other hand, have a relatively larger number of blades that rotate to drill holes in the lawn, increasing soil aeration and water permeability, helping plants absorb nutrients better, and simultaneously cutting off rootstocks to stimulate new root growth.

[0003] Currently, most lawn aerators use a front and rear wheel system, which generally results in shallow holes, especially when the front wheel encounters small slopes or hills, affecting soil aeration. For example, the existing patent CN212344404U discloses a lawn aerator for landscaping projects, which includes a frame, a roller, and a punching needle. Therefore, to improve the punching quality of lawn aerators, improvements are needed. Furthermore, most existing aerators require lifting the punching device to turn, which affects their efficiency in practical applications. Summary of the Invention

[0004] This utility model addresses the technical problems existing in the aforementioned rolling lawn aerator by proposing a rolling lawn aerator with a reasonable design, multiple counterweight measures, which is conducive to improving aerator quality, easy to turn, and improves equipment performance.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] As shown in Figures 1, 2, and 3, this utility model provides a rolling lawn aerator, including a frame 1. An engine 2 and a handle 3 are mounted on the frame 1. A transmission mechanism 4 is located at the power output end of the engine 2, and a drilling device 5 is located at the power output end of the transmission mechanism 4. The drilling device 5 includes multiple drilling blades 51. The engine 2 is a Briggs 950cc engine with a built-in 6:1 reduction gear. The handle 3 is used to manually push the device forward on the lawn; however, most of the forward thrust is achieved by the continuous rolling of the drilling blades 51 after the engine 2 drives the drilling device 5. Based on this, the drilling device 5 provided by this utility model includes a drilling shaft 52, on which five sets of relatively independent drilling discs 53 are provided. The drilling discs 53 and the drilling shaft 52 are connected by a one-way key. The number of drilling cutters 51 provided on the drilling discs 53 is not less than six. A water tank 6 is provided in the forward direction of the drilling device 5. The water tank 6 has a cylindrical structure and its two ends are connected to the frame 1. The engine 2 is located above the water tank 6. The transmission mechanism 4 includes a belt drive assembly 41. A chain drive assembly 42 is provided at the power output end of the belt drive assembly 41. The chain drive assembly 42 includes a chain 421. On the transmission path of the chain 421, there are a first sprocket 422 coaxially connected to the belt drive assembly 41, a second sprocket 423 coaxially connected to the drilling device 5, a third sprocket 424 coaxially connected to the water tank 6, and a first tension sprocket 425 and a second tension sprocket 426 connected to the frame 1.

[0023] Specifically, by providing a sufficient number of perforating discs 53 and perforating cutters 51, this device ensures a high perforation density during its rolling motion. The water tank 6 has a water injection and sealing structure at its end. The cylindrical surface of the water tank 6 can roll and contact the lawn surface, serving as a support component for the perforation process and, together with the engine 2, providing crucial counterweight. By injecting different volumes of water into the water tank 6 in the forward direction of the perforating device 5, combined with the weight distribution effect of the engine 2, a good counterweight effect is achieved. The perforating device 5 achieves better perforation quality while rolling, especially with a significant improvement in perforation depth; the holes are no longer shallow, which promotes better soil aeration. Furthermore, the punching shaft 52 and the punching disc 53 of the punching device 5 are connected by a one-way key. The one-way key can be a rectangular or wedge-shaped block, which is installed in the keyway of the punching shaft 52. When the punching shaft 52 rotates, the one-way key will prevent the punching disc 53 from moving relative to the punching shaft 52 in the circumferential direction, thereby transmitting the torque of the punching shaft 52 to the punching disc 53, causing the punching disc 53 to rotate with the shaft, thus realizing the transmission of power. The punching disc 53 and the punching shaft 52 can be rotated relative to each other by retracting and rotating, and the direction of the frame 1 can be manually adjusted by operating the handle 3, thereby improving the working efficiency of this equipment in specific application scenarios.

[0024] To improve the drilling quality of this device, adjustable counterweight components 7 are provided on both sides of the frame 1. Each counterweight component 7 includes a groove 71 containing a solid steel bar 72. A stop block 73, connected to the frame 1, is located on the front side of the groove 71. The solid steel bar has a locking groove that engages with the stop block. Rotating the stop block 73 allows for engaging and disengaging the solid steel bar 72, facilitating the replacement of solid steel bars 72 of different masses. The high density and mass of the solid steel, acting as a counterweight, complements the water tank 6, further improving the center of gravity distribution of the device and enhancing the rolling drilling quality.

[0025] To achieve better soil aeration, considering the aeration density and distribution, the five aeration discs 53 provided in this invention include three spaced-apart single-row aeration discs 531 and two double-row aeration discs 532 located between the single-row aeration discs 531. Each single-row aeration disc 531 has one ring of six aeration tools 51, while each double-row aeration disc 532 has two rings of twelve aeration tools 51. The at least 42 aeration tools 51 in this device provide forward propulsion for the aeration device 5 through rolling aeration, and also achieve a better aeration density, which is beneficial for improving the aeration performance of the soil after aeration, thereby increasing the working efficiency of the equipment.

[0026] Furthermore, the punching tool 51 provided by this utility model is distributed in a star shape on the punching disc 53. The end and side of the punching tool 51 are respectively provided with a knife hole 511 and a soil discharge hole 512. The edge of the knife hole 511 is a cutting edge, which can be inserted into the ground and turn up the soil under the action of counterweight and rolling power. The soil discharge hole 512 can throw out the soil inside the punching tool 51 to ensure the continuous punching performance of the punching device 5.

[0027] To improve the working efficiency of this device, a walking device 8 is provided on the frame 1 of this utility model, which includes two rear wheels 81 and a rear wheel frame 82. The two rear wheels 81 are independent of each other, and the rear wheel frame 82 is axled to the frame 1. A control component 9 for controlling the ground clearance of the rear wheels 81 is provided below the handle 3. By manually controlling the control component 9, the ground clearance of the walking device 8 can be changed. When the ground clearance is reduced, the rear wheels 81 can contact the ground, providing direct support and walking, and the drilling device 5 is off the ground and in a non-working state. When the ground clearance of the rear wheels 81 is increased, it means that they are in a suspended state, which can play a certain role in limiting the depth, and most importantly, it puts the drilling device 5 into working state to realize rolling drilling operations.

[0028] Specifically, the control component 9 provided by this utility model includes a U-shaped handle 91 hinged to the armrest 3, a pull rod 92 hinged to the side of the U-shaped handle 91, the end of the pull rod 92 hinged to the rear wheel frame 82, and a folding arm 93 near the end of the pull rod 92, the folding arm 93 hinged to the frame 1. The pull rod 92, rear wheel frame 82, folding arm 93, and the invisible rod between the folding arm 93 and the rear wheel frame 82 constitute a linkage mechanism. The control component 9 adopts a robust rod structure and connectors, which can realize manual height adjustment. For example, when the U-shaped handle 91 is pushed down, the pull rod 92 produces planar movement, especially causing its end to drive the rear wheel frame 82 to lift up, the rear wheel 81 to leave the ground, and the handrail 3 is pressed down, causing the equipment to tilt up, and the drilling tool 51 will insert into the soil. When the U-shaped handle 91 is pulled up, the rear wheel frame 82 is pressed down to contact the ground, and the drilling tool 51 is higher than the ground. At this time, the whole machine can be pushed on the ground for easy transportation. This realizes the quick switching of different modes of the equipment. The design is ingenious and highly practical.

[0029] To improve the working safety of this equipment, a bumper 10 is provided on the frame 1. The bumper is located above the water tank 6 and in front of the engine 2.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
