Description

Technical Field

[0001] The present invention relates to the technical field of garden maintenance, and specifically relates to a power tiller for garden maintenance. Background Art

[0002] Garden landscapes can prevent wind and sand, adsorb dust, sterilize, reduce noise, and adsorb toxic substances, which has a certain natural environmental protection effect on the physical and mental health of residents. At the same time, it is also beneficial to improve people's living standards, living environment, and the sustainability of the city. The importance of urban greening and garden construction has become a common concern. Loosening the soil in gardens is mainly to increase the air permeability of the soil, thereby promoting the respiration of vegetation roots.

[0003] After retrieval, a patent with the Chinese patent number CN109348756B discloses a multifunctional garden power tiller, including a machine base, a push rod connected to the machine base and inclined; wheels rotatably connected to the machine base; a soil loosening device extending into the soil and turning the soil when the machine base moves forward; a fertilizing device for holding fertilizers; the fertilizing device provides fertilizers into the soil loosening device when the machine base moves forward and then releases them into the soil; a watering device for applying water and / or liquid solutions to the soil after loosening. By setting the liquid pouring device, the present invention can water and irrigate the vegetation when loosening the soil, and can complete two tasks at one time during this process, saving working time.

[0004] However, existing power tillers generally use mechanical adjustment structures. By combining a threaded rod lifting device with manual repeated rotation of the turntable, it is time-consuming and laborious. When operating in large parks or tree-lined road areas, frequent adjustment leads to a reduction in work efficiency. In addition, in garden maintenance, the lawn and ground cover plants require shallow soil loosening of 5 - 8 cm, and for some ancient and famous tree deep-rooted arbors, layered soil loosening of 15 - 20 cm is required. For composite green belt operations, such as the mixed planting area of shrubs, turf, and flowers in urban road green belts, single-depth soil loosening is likely to cause damage to the soil structure. However, existing equipment is difficult to accurately control the depth and is difficult to meet the requirements of multiple regions and multiple vegetation types in garden maintenance. Based on this, the present invention designs a power tiller for garden maintenance to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a power tiller for garden maintenance, which solves the problem of being unable to adjust the height of the soil loosening structure in the background art.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: A power tiller for garden maintenance, comprising: Vehicle body, a support frame is fixedly connected to the top of the vehicle body, a motor base is fixedly connected to the top of the support frame, and a dual-axis motor is installed in the inner cavity of the motor base for adjusting the loosening height.

[0007] Soil loosening mechanism, the soil loosening mechanism is located at the back of the dual-axis motor and is used for soil loosening work in garden maintenance. The soil loosening mechanism includes a lifting component, a linkage component and a working component. The lifting component is located at the back of the dual-axis motor and is used for lifting and lowering the height of the working component. The linkage component is located on one side of the lifting component and is used for the stable lifting of the working component. The working component is installed at the bottom of the lifting component and is used to contact the soil and realize the soil loosening process.

[0008] Leveling component, the leveling component is installed on the front of the dual-axis motor and is used for leveling the soil surface.

[0009] Preferably, the lifting component includes a driving shaft fixedly connected to the output shaft on the back of the dual-axis motor. A driving gear is installed on the outer ring of the driving shaft. The lifting component further includes a support plate installed on the top of the support frame. A driven shaft is rotatably connected in the inner cavity of the support plate. A driven gear is installed on the outer ring of the back of the driven shaft.

[0010] Preferably, a connecting gear is installed on the front of the driven shaft. A linkage shaft is rotatably connected in the inner cavity of the support plate. A linkage gear is installed on the outer ring of the linkage shaft. The connecting gear and the linkage gear are meshed with each other. Synchronous wheels are installed on the outer rings of the linkage shaft and the driving shaft respectively. A synchronous belt is installed on the outer rings of the synchronous wheels for connection.

[0011] Through the above technical solution, when the dual-axis motor is started, the output shaft on its back drives the driving shaft to rotate, and the driving gear installed on the outer ring of the driving shaft will also rotate accordingly. The synchronous wheels on the outer rings of the driving shaft and the linkage shaft are connected by a synchronous belt, so that the linkage shaft will also rotate. The connecting gear at the front end of the driven shaft and the linkage gear on the outer ring of the linkage shaft are meshed with each other, and then the driven shaft and the driven gear rotate together, thus finally realizing the synchronous rotation of the driving gear and the driven gear.

[0012] Preferably, the linkage component includes a fixed rod installed on the top of the support frame. A top plate is installed on the top of the fixed rod. A plurality of telescopic rods are fixedly connected to the bottom of the top plate and are distributed in a rectangular array. A lifting frame is installed at the bottom of the telescopic rods. Rack bars are installed on both sides of the lifting frame. The rack bars are meshed with the driving gear and the driven gear respectively. A fixed seat is installed on one side of the lifting frame and the fixed seat is slidably sleeved on the outer ring of the fixed rod.

[0013] Preferably, the linkage assembly further includes a hydraulic rod installed at the bottom of the lifting frame. The bottom of the output end of the hydraulic rod is fixedly connected with a lifting seat. Rotating seats are installed on the front and back of the lifting seat. The front and back of the bottom of the lifting frame are both hinged with connecting plates. The bottom of the connecting plate is hinged with a rotating frame, and the rotating frame and the rotating seat are rotationally connected through a pin shaft.

[0014] Preferably, the working assembly includes a driving motor installed on one side of the lifting seat. The output shaft of the driving motor is fixedly connected with a working shaft. A hub is installed on the outer circle of the working shaft. A wheel disc is installed on the outer circle of the hub. Loosening knives are installed on the outer circle of the wheel disc and are distributed in a circumferential array.

[0015] It can be seen from the above technical solutions that the hydraulic rod in the linkage assembly drives the lifting seat to move up and down. The lifting seat is connected to the rotating frame through the rotating seat and the connecting plate, ensuring the stability of the working assembly during the lifting process, and enabling fine adjustment of the height position of the working assembly. When the driving motor is started, the loosening knives rotate at a high speed, directly contact the soil and realize the soil loosening function. The loosening knives are designed with a circumferential array distribution, which can evenly cut and loosen the soil, improving the soil loosening efficiency. Through the height adjustment of the lifting assembly and the linkage assembly, the working assembly can accurately reach the set depth, realizing the layered soil loosening of shallow and deep soils, avoiding damage to the soil structure, and especially suitable for the operation requirements of urban green belts and composite greening areas.

[0016] Preferably, the leveling assembly includes a driving lead screw fixedly connected to the front of the output shaft of the double-shaft motor. A partition is also installed on the top of the vehicle body. A connecting seat is installed on one side of the partition. A driven lead screw is rotationally connected in the inner cavity of the connecting seat. Linkage wheels are installed on the front of the driving lead screw and the driven lead screw, and a linkage belt is installed on the outer circle of the linkage wheels for connection.

[0017] It can be seen from the above technical solutions that synchronous rotation is achieved through the linkage wheels and the linkage belt. The driving lead screw and the driven lead screw are both bidirectional lead screws. The moving blocks on their outer circles approach or move away from each other under the action of the threads, thereby driving the rotating plate to rotate. The rotating plate is connected to the working block through a pin shaft, enabling the working block to move up and down. The slider at the bottom of the working block slides in the chute at the top of the leveling block, enabling the leveling block to lift smoothly. The leveling strip at the bottom of the leveling block directly contacts the soil to complete the leveling operation of the soil surface.

[0018] Preferably, the driving lead screw and the driven lead screw are both bidirectional lead screws, and moving blocks are threadedly connected to their outer circles. There are two groups of moving blocks, which are respectively located at the threads in different directions. The bottoms of the moving blocks are both hinged with rotating plates, and the rotating plates are rotationally connected through a pin shaft. The bottom of the rotating plate is hinged with a working block. The bottom of the working block is slidably connected with a leveling block. The bottom of the leveling block is fixedly connected with a leveling strip.

[0019] Preferably, a chute is formed at the top of the leveling block, sliders are fixedly connected to the bottoms of the working blocks, and the sliders are slidably connected to the inner cavity of the chute, and both the sliders and the chute are in a "convex" shape structure.

[0020] Through the above technical solution, it can be seen that the "convex" shape structure design of the slider and the chute enhances the stability and accuracy of the leveling process and ensures the flatness of the soil surface.

[0021] Preferably, a seat is installed on the top of the vehicle body, a control panel is installed on the back of the seat and the control panel is electrically connected to the double-shaft motor, a water tank is further installed in the inner cavity of the support frame, and a sprinkler head is installed on the back of the water tank for irrigation after soil loosening.

[0022] Through the above technical solution, it can be seen that the water tank and the sprinkler head installed on the top of the vehicle body form the core of the irrigation system. The water tank has a sufficient capacity to meet the irrigation needs of large-area operations. The sprinkler head is installed on the back of the vehicle body, and its spraying range covers the entire operation area. By starting the irrigation function through the control panel, the water in the water tank is transported to the sprinkler head through a pipeline and evenly sprayed on the soil, avoiding the waste of water resources, and is especially suitable for the soil moisture preservation and vegetation maintenance needs in garden maintenance.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. In the present invention, aiming at the problem that the existing soil loosener relies on a mechanical adjustment structure and the time-consuming and laborious process of lifting the device by a threaded rod combined with manual repeated rotation of the turntable, a lifting component driven by a double-shaft motor is adopted, and the transmission of a synchronous pulley and a synchronous belt is used to realize the precise lifting of the working component, improving the working efficiency. Especially when operating in large parks or tree-lined roads, it can quickly adapt to the soil loosening requirements of different depths and avoid delays caused by frequent adjustments.

[0024] 2. In the present invention, aiming at the problem that it is difficult for the existing equipment to accurately control the soil loosening depth and it is difficult to meet the needs of multiple regions and multiple vegetation types such as lawns, ground cover plants, ancient and famous trees, and composite green belts in garden maintenance, through the coordinated work of the lifting component and the linkage component, combined with the fine-tuning function of the hydraulic rod, it can realize the layered soil loosening of shallow and deep soils. The circumferential array distribution design of the soil loosening knives ensures the uniformity and high efficiency of soil loosening and avoids damage to the soil structure, and is especially suitable for the operation requirements of urban green belts and composite greening areas.

[0025] 3. In the present invention, through the coordinated action of transmission components such as gears, racks, and synchronous belts, the stability and accuracy of the lifting of the working components are ensured. The cooperation of the hydraulic rod, rotating seat, connecting plate, and rotating frame in the linkage component further stabilizes the soil loosening process, enabling the working components to remain stable during lifting and soil loosening operations, and improving the quality of soil loosening; the leveling component can smoothly level the soil surface through structures such as a bidirectional lead screw, moving block, rotating plate, and leveling block.

[0040] Working principle: The soil loosener takes the vehicle body 101 as the load-bearing main body. A support frame 102 is fixedly connected to the top of the vehicle body 101. A motor base 103 is installed on the top of the support frame 102. A dual-shaft motor 104 is installed in the inner cavity of the motor base 103, serving as the core power source of the entire device. When the dual-shaft motor 104 starts, the output shaft on its back drives the drive shaft 105 to rotate, and the drive gear 106 installed on the outer ring of the drive shaft 105 will also rotate accordingly. The synchronous wheels 113 on the outer rings of the drive shaft 105 and the linkage shaft 111 are connected by a synchronous belt, causing the linkage shaft 111 to rotate. The connecting gear 110 at the front end of the driven shaft 108 meshes with the linkage gear 112 on the outer ring of the linkage shaft 111, and then the driven shaft 108 and the driven gear 109 rotate together, ultimately achieving the synchronous rotation of the drive gear 106 and the driven gear 109. During operation, the drive gear 106 and the driven gear 109 drive the lifting frame 204 to move up and down along the fixed rod 201. The racks 205 on both sides of the lifting frame 204 mesh with the drive gear 106 and the driven gear 109, further ensuring the stability and accuracy of the lifting process of the working component 3.

[0041] The hydraulic rod 207 in the linkage component 2 drives the lifting seat 208 to move up and down. The lifting seat 208 is connected to the rotating frame 211 through the rotating seat 209 and the connecting plate 210, ensuring the stability of the working component 3 during the lifting process and enabling fine adjustment of the height position of the working component 3.

Its output shaft drives the soil loosening blade 305 to rotate through the working shaft 302, the hub 303, and the wheel disc 304, achieving efficient soil loosening operation.

[0042] The front output shaft of the dual-shaft motor 104 drives the drive lead screw 401 to rotate. The drive lead screw 401 and the driven lead screw 404 are connected by a linkage wheel 405 and a linkage belt 406 to achieve synchronous rotation. Both the drive lead screw 401 and the driven lead screw 404 are bidirectional lead screws. The moving blocks 407 on their outer rings approach or move away from each other under the action of the thread. The rotating plate 408 hinged at the bottom of the moving block 407 is rotationally connected through a pin shaft, driving the working block 409 to lift. The slider 413 at the bottom of the working block 409 slides in the chute 412 on the top of the leveling block 410, causing the leveling block 410 to lift. When needed, the leveling block 410 and the leveling strip 411 are controlled to approach the ground for leveling operation. The slider 413 and the chute 412 are in a "convex" shape structure, enhancing the connection stability and ensuring the high precision of the leveling operation.
