Description

Technical Field

[0001] This utility model relates to the field of lawn maintenance equipment, and in particular to a device that can integrate lawn compaction, aeration, and application of pesticides and fertilizers. Background Technology

[0002] Lawns are characterized by their rapid growth and significant benefits, making them an important component of urban green spaces. There are two main methods for planting lawns: sowing grass seeds and laying turf. Laying pre-cultivated turf is more commonly used in landscaping construction due to its advantages such as rapid establishment, low soil requirements, and good aesthetic appeal. The planting method generally involves transplanting the cultivated turf to the planting site, then compacting it using a compaction device. Later maintenance requires aeration and application of pesticides or liquid fertilizers.

[0003] Existing technologies also include compaction and perforation equipment. For example, Chinese utility model patent CN205124442U discloses an adjustable-weight lawn roller, which is installed behind a walking tractor and perforates the lawn as the tractor moves forward. Specifically, the device includes a tow hook for connecting to the walking tractor, a frame consisting of a housing, support arms, and a support bracket, a rotating shaft on the frame, and a cylindrical roller (i.e., a perforating roller) mounted on the shaft. Steel nails are installed on the outer surface of the cylindrical roller. As the walking tractor moves forward, the cylindrical roller rotates, contacting the ground and perforating it with the steel nails. Other products also include devices for compacting lawns, such as Chinese utility model patent CN204409035U, which discloses an adjustable-weight lawn roller.

[0004] The above-mentioned technical solutions are only applicable to one of the scenarios. In the actual maintenance process, it is necessary to compact the lawn, aerate the lawn, and apply pesticides and fertilizers at different times. For the above three usage scenarios, the existing technology requires a separate device for each scenario. That is, in the maintenance of the lawn throughout its entire life cycle, at least three devices need to be configured, and each device with a function requires a certain purchase and maintenance cost. Utility Model Content

[0005] In view of this, the present invention provides a device that integrates lawn compaction, aeration, and pesticide and fertilizer application to solve the problem that the existing technology requires separate equipment for compaction, aeration, pesticide and fertilizer application for transplanted lawns, resulting in high lawn maintenance costs.

[0006] An integrated device for lawn compaction, aeration, and pesticide / fertilization includes a walking tractor. The walking tractor includes a drive shaft and tires detachably connected to the drive shaft. The device also includes a frame connected to the rear of the walking tractor. The frame has a connecting part for connecting the walking tractor. The end of the frame away from the connecting part has a mounting shaft or mounting hole for mounting a wheel system. The axis of the mounting shaft or mounting hole is parallel to the axis of the drive shaft. The device also includes a driven compaction wheel and a driven aeration wheel for mounting on the mounting hole or mounting shaft, and an active compaction wheel and an active aeration wheel for mounting on the drive shaft. The end of the active compaction wheel away from the walking tractor after being mounted on the drive shaft protrudes beyond the driven compaction wheel. The end of the active aeration wheel away from the walking tractor after being mounted on the drive shaft protrudes beyond the driven aeration wheel. The frame also has a holding structure for holding a water tank, and the water tank has a spray nozzle with a pressure pump.

[0007] Furthermore, both the active compaction wheel and the active perforation wheel include a cylindrical metal roller with one end closed and the other end open, and the closed end is provided with a quick-release structure for installation and removal from the drive shaft.

[0008] Furthermore, the frame includes a cubic frame structure at one end away from the connection portion, and the mounting shaft or mounting hole is disposed on the cubic frame structure.

[0009] Furthermore, the holding structure is a limiting bracket set at the bottom of the cubic frame structure for holding the water tank.

[0010] Furthermore, the device also includes tires for mounting on the frame, the tires being used to mount on the outside of the frame when the water tank is mounted on the holding structure.

[0011] The beneficial effects of this utility model, which integrates lawn compaction, aeration, and pesticide / fertilizer application, are as follows: The device is driven by a walking tractor; the detachable tires facilitate removal from the tractor, allowing for the addition of other tools; the frame with mounting shafts or holes allows for the installation of driven compaction or aeration wheels; and the active compaction and aeration wheels facilitate replacement as needed when the tractor tires are removed. The compaction wheel is used for compaction, and the aeration wheel for aeration; furthermore, the active compaction wheel, once mounted on the frame, is positioned away from the walking tractor. One end protrudes from the driven compaction wheel, and the other end of the active perforating wheel, after being mounted on the frame, protrudes from the driven perforating wheel to increase the compaction and perforation range, thereby improving efficiency. In addition, by setting up a water tank holding structure, it is easy to install the water tank under specific working conditions, and the spray nozzle on the water tank facilitates the application of pesticides and fertilizers. In other words, by modularizing the tools used in various scenarios, different functions can be achieved by installing modular components while keeping the walking tractor and frame as the main body. This solves the problem of high lawn maintenance costs caused by the need for separate equipment for compaction, perforation, and pesticide and fertilizer application in existing technologies.

[0025] To better understand the technical solution of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings.

[0026] In Embodiment 1 of this utility model, a device that integrates lawn compaction, aeration, and pesticide and fertilizer application (hereinafter referred to as the integrated device) is used:

[0027] like Figure 1 and Figure 5 As shown, the integrated device includes a walking tractor 1 and a frame 2 connected to the walking tractor 1. The walking tractor 1 includes a drive shaft and tires 3 detachably connected to the drive shaft. A tow hook is also provided at the rear of the walking tractor 1, which is used to connect to the frame 2 and provide traction to the frame 2. The walking tractor 1 is a mature product in the prior art and will not be described in detail here. The frame 2 is provided with a connecting part for connecting the walking tractor 1, specifically, a connecting hook adapted to the tow hook. The frame 2 includes cross-arranged connecting arms, the ends of which are connected to a cubic frame structure. The bottom of the cubic frame structure is provided with mounting holes, through which a driven shaft can be inserted to install a wheel system. As the walking tractor 1 moves forward, the frame 2 moves forward with the walking tractor 1. The bottom of the cubic frame structure is also provided with a limiting bracket for holding a water tank 6. When the water tank 6 is placed inside the cubic frame structure, a tire 3 is installed on the outside of the mounting hole, so that the tire 3 is located outside the water tank 6 and does not encroach on the position of the water tank 6, thus eliminating the need to install the water tank 6 too high. A spray nozzle with a pressure pump is installed on the water tank, enabling pesticide and fertilizer application while the hand-held tractor 1 is moving forward. Of course, in other embodiments, the water tank can also be located above the wheel system, in which case its center of gravity is higher and its stability is reduced, but space utilization is improved. Alternatively, in other embodiments, a mounting shaft can be set on the frame, and correspondingly, the other wheel systems need to be provided with holes adapted to the mounting shaft.

[0028] like Figure 2 and Figure 3As shown, to achieve compaction and aeration of the lawn, compaction wheels and aeration wheels are also provided. Specifically, the compaction wheels include an active compaction wheel 41 for mounting on the drive shaft and a driven compaction wheel 42 for mounting on the mounting holes of the frame 2. The active compaction wheel 41 is a cylindrical metal roller with one open end and one closed end. One end of the active compaction wheel 41 is open, and the other end is closed. A quick-release structure for mounting and dismounting with the drive shaft is provided on the sealing plate of the closed end, wherein the quick-release structure is a connection structure adapted to the flange on the drive shaft. Of course, in other embodiments, if the drive shaft is a spline quick-release shaft, the quick-release structure on the active compaction wheel 41 should also be adjusted accordingly. Alternatively, in other embodiments, the active compaction wheel may not be open at one end and closed at the other, but rather both ends may be open. The active compaction wheel has a mounting plate for connecting with the drive shaft, and the mounting plate is fixedly connected to the inner wall of the active compaction wheel through a bracket.

[0029] The driven compaction wheel 42 is a cylindrical metal cylinder with mounting shafts at both ends for connecting to mounting holes on the frame 2. Specifically, it can be a metal cylinder with both ends closed, with mounting shafts respectively provided on the end plates. Alternatively, the driven compaction wheel 42 can be a metal cylinder with both ends open, with the mounting shafts of the driven compaction wheel 42 contacting and connecting to the inner surface of the cylinder through a bracket. The axial length of the driven compaction wheel 42 is not greater than the width of the frame 2, meaning that the area that the driven compaction wheel 42 can compact during its forward movement does not exceed the range of the frame 2. To expand the compaction area and improve compaction efficiency, the end of the driving compaction wheel 41, after being installed on the frame 2, protrudes from the driven compaction wheel 42 away from the hand-held tractor 1. In the forward direction, the driving compaction wheel 41 and the driven compaction wheel 42 overlap, thereby facilitating the expansion of the compaction area. At the same time, the driven compaction wheel 42 can also perform secondary compaction on the area compacted by the driving compaction wheel 41, improving the compaction quality.

[0030] like Figure 4 As shown, similarly, the punching wheel includes an active punching wheel 51 for mounting on the drive shaft and a driven punching wheel 52 for mounting on the frame 2. The active punching wheel 51 has a similar structure to the active compaction wheel 41, except that a puncher is also provided on the outer circumferential surface of the active punching wheel 51. In this embodiment, the puncher is a steel nail. Specifically, the steel nail can be welded to the outer circumference of the active punching wheel 51 to punch holes in the ground during the rotation of the punching wheel. Similarly, the driven punching wheel 52 has a similar main structure to the driven compaction wheel 42, except that a steel nail is also provided on the outer circumferential surface of the driven punching wheel 52. Of course, in other embodiments, the puncher can also be set as a sawtooth or other form.

[0031] By changing the gear train, the device can change its operating mode in different scenarios. For example... Figure 2 and Figure 3 As shown, the active compaction wheel 41 is mounted on the drive shaft, and the driven compaction wheel 42 is mounted on the frame 2, thus enabling the compaction of the lawn. Alternatively, as... Figure 4 As shown, the active aerator wheel 51 is mounted on the drive shaft, and the driven aerator wheel 52 is mounted on the frame 2, enabling aeration of the lawn. Alternatively, tires 3 are mounted on both the drive shaft and the frame 2, and a water tank 6 with a spray nozzle is placed on the frame 2, allowing for pesticide and fertilizer application. Since the front and rear parts of the device are separate, different accessories can be installed on the walking tractor 1 and the frame 2 respectively to achieve both functions simultaneously while moving forward. For example, the active compaction wheel is mounted on the drive shaft, tires are mounted on the frame, and a water tank with a spray nozzle is mounted on the frame; in this case, the front of the device can perform compaction work, while the rear performs pesticide and fertilizer application, improving maintenance efficiency.

[0032] It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
