Description

Technical Field

[0001] This application relates to the field of landscaping engineering equipment technology, and in particular to a soil loosening device for landscaping engineering with a loosening effect. Background Technology

[0002] During the construction and maintenance of landscaping projects, soil loosening devices are needed to break up and loosen the soil in order to improve its aeration and water permeability and ensure the normal growth of the roots of seedlings in the garden. Traditional soil loosening devices used in landscaping projects can be divided into several categories according to their structure: manual tools, small motorized equipment and large supporting machinery.

[0003] Manual tools suffer from low efficiency and uneven soil loosening depth. Large-scale machinery has high requirements for the work site and can easily trample on lawns and seedlings. While small motorized equipment can loosen soil with minimal impact on the landscaping environment, existing small motorized equipment typically uses a single set of tillers, and the loosening depth relies on the operator's experience or manual adjustment, resulting in rough adjustment. Furthermore, since landscaping surfaces have many uneven areas, using small motorized equipment can easily lead to some areas being over-tilled while others are under-loosened, resulting in poor soil loosening effects for landscaping. Summary of the Invention

[0004] In order to solve the problems of poor soil loosening depth adjustment and poor soil loosening effect of existing small and medium-sized motorized equipment, this application provides a soil loosening device for landscaping projects with loosening effect.

[0005] This application provides a soil loosening device for landscaping projects with a loosening effect, which adopts the following technical solution: A soil loosening device for landscaping projects with a loosening effect includes: a frame, a pair of traveling wheels, a multi-stage crushing and loosening component, and an adjustable floating limit component. The pair of traveling wheels is rotatably mounted below the frame. The multi-stage crushing and loosening component is located below the frame and includes a reduction gearbox, multiple primary crushing blades, multiple crushing blades, and a gasoline engine. The reduction gearbox is positioned between the pair of traveling wheels and has one input end and multiple output ends. The multiple output ends are respectively located on both sides of the reduction gearbox and are respectively connected to the multiple primary crushing blades. The blade assembly and multiple crushing blade assemblies are fixedly connected. The gasoline engine is fixedly mounted above the reduction gearbox, and the output end of the gasoline engine is fixedly connected to the input end of the reduction gearbox. The adjustable floating limit assembly is mounted above the reduction gearbox. The adjustable floating limit assembly includes a floating plate, multiple buffer connectors, and multiple electric telescopic rods. The floating plate is fixedly mounted above the reduction gearbox, multiple buffer connectors are fixedly mounted above the floating plate, and multiple electric telescopic rods are fixedly mounted above the frame. The telescopic ends of the multiple electric telescopic rods are respectively hinged to the multiple buffer connectors.

[0006] By adopting the above technical solution, in practical application, a pair of walking wheels supports and limits the frame and assists in movement. After the loosening device moves to the work area, the overall height of the multiple crushing and loosening components is adjusted by controlling the extension of the telescopic ends of multiple electric telescopic rods according to the actual loosening requirements, thereby regulating the loosening depth. Subsequently, the gasoline engine is controlled to run, so that multiple primary crushing blade groups and multiple crushing blade groups can rotate synchronously with the rotation of the gearbox output end, and thus the loosening of the work area is carried out through the cooperation of multiple primary crushing blade groups and multiple crushing blade groups.

[0007] Optionally, it also includes a protective frame and handrails. The protective frame is fixedly installed above the frame and sleeved on the outside of the gasoline engine and multiple electric telescopic rods. The handrails are fixedly installed on one side of the frame.

[0008] By adopting the above technical solution, the protective frame provides a protective enclosure for the gasoline engine and multiple electric telescopic poles, preventing damage caused by collisions between the seedling branches and these components during actual application. The frame is slidably pushed forward by applying a pushing force to the handrails.

[0009] Optionally, the multi-stage crushing and loosening assembly further includes a drive bevel gear, a driven bevel gear, a drive shaft, and a driving gear. The drive bevel gear is rotatably disposed within a reduction gearbox and is fixedly connected to the output end of the gasoline engine. The driven bevel gear is disposed below the drive bevel gear and meshes with it. The drive shaft passes through the driven bevel gear and is rotatably connected to the reduction gearbox. The driving gear is fixedly sleeved on the outside of the driven bevel gear.

[0010] By adopting the above technical solution, the transmission bevel gear and the driven bevel gear are matched so that the transmission shaft can drive the driving gear to rotate synchronously with the rotation of the gasoline engine output end.

[0011] Optionally, the multi-stage crushing and loosening assembly further includes a driven gear, a pair of output shafts, and a pair of loosening drive gears. The driven gear is rotatably disposed within the reduction gearbox and meshes with the driving gear. The pair of output shafts passes through the reduction gearbox, and multiple primary crushing blade groups and multiple crushing blade groups are respectively fixedly sleeved on the outside of the pair of output shafts. The pair of loosening drive gears are respectively fixedly sleeved on the outside of the pair of output shafts and both mesh with the driven gears.

[0012] By adopting the above technical solution, in practical application, the meshing of the driving gear and the driven gear enables the driven gear to rotate synchronously with the rotation of the driving gear, thereby driving the soil loosening drive gears on both sides to rotate synchronously. The soil loosening drive gears drive the output shaft to rotate, thereby driving multiple primary crushing blade groups and multiple crushing blade groups to crush and loosen the soil.

[0013] Optionally, the multi-stage crushing and loosening assembly further includes a leveling rake, the upper end of which is hinged to a floating plate, and the lower end of which has an arc-shaped comb-like structure.

[0014] By adopting the above technical solution, the soil after being broken and turned over is further broken and leveled by a leveling rake, which improves the effect of loosening soil.

[0015] Optionally, there are four buffer connectors and four electric telescopic rods. The buffer connectors and electric telescopic rods are arranged in a one-to-one correspondence and are all located at the four corners of the floating plate.

[0016] By adopting the above technical solution, multiple buffer connectors are used to connect and limit the floating plate and the electric telescopic rod.

[0017] Optionally, the buffer connector includes a fixed base, a telescopic connecting block, and multiple sets of buffer springs. The fixed base is fixedly disposed above the floating plate; the telescopic connecting block is slidably disposed within the fixed base; and the multiple sets of buffer springs are disposed between the fixed base and the telescopic connecting block, with both ends of the multiple sets of buffer springs being fixedly connected to the fixed base and the telescopic connecting block, respectively.

[0018] By adopting the above technical solution, in practical applications, the telescopic connecting block connects the fixed seat and the telescopic end of the electric telescopic pole. The telescopic connecting block and the fixed seat are buffered by compressing multiple sets of buffer springs, which avoids the floating plate directly transmitting the force to the telescopic end of the electric telescopic pole, thus preventing the electric telescopic pole from having a shortened service life or getting stuck.

[0019] Optionally, the telescopic connecting block has a positioning pin hole at one end outside the fixed base, and a connecting pin is inserted into the positioning pin hole. The telescopic end of the electric telescopic rod is hinged to the telescopic connecting block through the connecting pin.

[0020] By adopting the above technical solution, the telescopic end of the electric telescopic pole is hinged to the telescopic connecting block using a connecting pin, which ensures the flexibility of movement and avoids jamming between the telescopic connecting block and the telescopic end of the electric telescopic pole during operation.

[0021] Optionally, the adjustable floating limit assembly further includes multiple limit telescopic rods, with a total of 4 limit telescopic rods. The 4 limit telescopic rods are arranged in pairs, and the two pairs of limit telescopic rods are symmetrically arranged on both sides of the floating plate. The two ends of each limit telescopic rod are respectively hinged to the floating plate and the frame.

[0022] By adopting the above technical solution, the frame and floating plate are auxiliaryly connected using multiple limiting telescopic rods, improving the assembly stability of the floating plate. Simultaneously, by varying the extension and retraction of the multiple limiting telescopic rods, the gearbox can adapt synchronously to changes in terrain, enhancing the soil loosening device's adaptability to different terrains.

[0023] Optionally, the limiting telescopic rod includes a fixed outer cylinder, a telescopic inner rod, and a connecting spring. The fixed outer cylinder is a cylindrical component with one open end, and one end of the fixed outer cylinder is hinged to the frame. The telescopic inner rod is slidably engaged with the open end of the fixed outer cylinder, and the end of the telescopic inner rod located outside the fixed outer cylinder is hinged to the floating plate. The connecting spring is fixedly disposed between the fixed outer cylinder and the telescopic inner rod.

[0024] By adopting the above technical solution, in practical applications, the fixed outer cylinder and the telescopic inner rod are connected and limited by the connecting spring. The telescopic rod can elastically connect the floating plate and the frame by compressing or resetting the connecting spring.

[0025] In summary, the embodiments of the present invention provide a soil loosening device for landscaping projects with a loosening effect, including at least one of the following beneficial technical effects: 1. By setting up multiple crushing and loosening components, the soil in the garden operation area can be crushed and loosened in multiple ways, which improves the effect of loosening the soil in the garden operation area; 2. By setting adjustable floating limit components, the soil loosening depth and angle can be flexibly adjusted according to the operation requirements. This not only enables soil loosening operations at a set depth in the garden operation area, but also improves the adaptability of the soil loosening device to the terrain of the garden operation area, avoiding the situation where some areas are over-tilled while others are not loosened properly.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1 to 8 This application will be described in further detail.

[0029] Combination Figure 1 and Figure 3 This application discloses a soil loosening device for landscaping projects with a loosening effect, comprising: a frame 1, a pair of traveling wheel sets 2, a multi-stage crushing and loosening component 3, and an adjustable floating limit component 4. The pair of traveling wheel sets 2 are rotatably mounted below the frame 1. The multi-stage crushing and loosening component 3 is located below the frame 1 and includes a reduction gearbox 301, multiple primary crushing blade sets 302, multiple crushing blade sets 303, and a gasoline engine 304. The adjustable floating limit component 4 is located above the reduction gearbox 301 and includes a floating plate 401, multiple buffer connectors 402, and multiple electric telescopic rods 403. In practical applications, the soil loosening device is moved to the work area by rotating the pair of traveling wheel sets 2. Subsequently, according to the actual soil loosening requirements, the overall height of the multi-stage crushing and loosening component 3 is adjusted by controlling the extension of the telescopic ends of the multiple electric telescopic rods 403, thereby regulating the soil loosening depth. Subsequently, the gasoline engine 304 is controlled to operate, so that multiple primary crushing blade groups 302 and multiple crushing blade groups 303 can rotate synchronously with the rotation of the output end of the reduction gearbox 301, thereby loosening the soil in the working area through the cooperation of multiple primary crushing blade groups 302 and multiple crushing blade groups 303.

[0030] Combination Figure 1 The protective frame 5 is fixedly installed above the frame 1 and is fitted over the gasoline engine 304 and multiple electric telescopic poles 403. The protective frame 5 provides a protective cover for the gasoline engine 304 and multiple electric telescopic poles 403, preventing damage caused by collisions between the seedling branches and the gasoline engine 304 and multiple electric telescopic poles 403 during actual application.

[0031] Combination Figure 1 The handrail 6 is fixedly installed on one side of the frame 1. The frame 1 is slidably pushed by applying a pushing force to the handrail 6.

[0032] Combination Figure 1The reduction gearbox 301 is positioned between a pair of traveling wheel sets 2, and has one input end and multiple output ends. The multiple output ends are respectively located on both sides of the reduction gearbox 301 and are fixedly connected to multiple primary crushing blade sets 302 and multiple crushing blade sets 303. The soil in the garden operation area is double-crushed and loosened through the cooperation of the multiple primary crushing blade sets 302 and multiple crushing blade sets 303.

[0033] Specifically, in practical applications, different soil loosening blades can be selected according to the hardness of the soil in the work area.

[0034] Combination Figure 1 and Figure 4 The gasoline engine 304 is fixedly mounted above the reduction gearbox 301, and the output end of the gasoline engine 304 is fixedly connected to the input end of the reduction gearbox 301. By controlling the operation of the gasoline engine 304, multiple primary crushing blade groups 302 and multiple crushing blade groups 303 are rotated and driven, thereby enabling the loosening of soil in the garden operation area.

[0035] Combination Figure 5 and Figure 6 The multi-stage crushing and loosening assembly 3 also includes a drive bevel gear 305, a driven bevel gear 306, a drive shaft 307, and a drive gear 308. The drive bevel gear 305 is rotatably mounted inside the reduction gearbox 301 and is fixedly connected to the output end of the gasoline engine 304. The driven bevel gear 306 is located below the drive bevel gear 305 and meshes with it. The drive shaft 307 passes through the driven bevel gear 306 and is rotatably connected to the reduction gearbox 301. The drive gear 308 is fixedly sleeved on the outside of the driven bevel gear 306. Through the engagement of the drive bevel gear 305 and the driven bevel gear 306, the drive shaft 307 can drive the drive gear 308 to rotate synchronously with the rotation of the output end of the gasoline engine 304.

[0036] Combination Figure 5 and Figure 6The multi-stage crushing and loosening assembly 3 also includes a driven gear 309, a pair of output shafts 310, and a pair of loosening drive gears 311. The driven gear 309 is rotatably mounted inside the reduction gearbox 301 and meshes with the drive gear 308. The pair of output shafts 310 pass through the reduction gearbox 301, and multiple primary crushing blade groups 302 and multiple crushing blade groups 303 are respectively fixedly sleeved on the outside of the pair of output shafts 310. The pair of loosening drive gears 311 are respectively fixedly sleeved on the outside of the pair of output shafts 310 and both mesh with the driven gear 309. Through the meshing of the drive gear 308 and the driven gear 309, the driven gear 309 can rotate synchronously with the rotation of the drive gear 308, thereby driving the loosening drive gears 311 on both sides to rotate synchronously. The loosening drive gears 311 drive the output shafts 310 to rotate, thereby driving the multiple primary crushing blade groups 302 and multiple crushing blade groups 303 to crush and loosen the soil.

[0037] Combination Figure 4 The multi-stage crushing and loosening component 3 also includes a leveling rake 312. The upper end of the leveling rake 312 is hinged to the floating plate 401, and the lower end of the leveling rake 312 has an arc-shaped comb-like structure. The leveling rake 312 assists in crushing and leveling the soil after it has been crushed and turned over, thereby improving the effectiveness of the soil loosening operation.

[0038] Combination Figure 1 and Figure 4 A floating plate 401 is fixedly installed above the gearbox 301, serving to assemble and secure the gearbox 301. Simultaneously, the height and tilt angle of the gearbox 301 are adjusted synchronously by adjusting the height and tilt angle of the floating plate 401.

[0039] Combination Figure 7 and Figure 8 Multiple buffer connectors 402 are fixedly installed above the floating plate 401, and the buffer connectors 402 are used to connect and limit the telescopic ends of the floating plate 401 and the electric telescopic rod 403.

[0040] Combination Figure 1 and Figure 4 Multiple electric telescopic rods 403 are fixedly installed above the frame 1, and the telescopic ends of the multiple electric telescopic rods 403 are respectively hinged to multiple buffer connectors 402. The height and tilt angle of the floating plate 401 are adjusted by controlling the telescopic ends of the multiple electric telescopic rods 403.

[0041] Specifically, a battery is installed on the top of the frame 1 to power multiple electric telescopic poles 403.

[0042] It should be noted that by controlling the synchronous extension or retraction of the telescopic ends of multiple electric telescopic rods 403, the reduction gearbox 301 is lowered or raised as a whole, thereby causing multiple primary crushing blade groups 302 and multiple crushing blade groups 303 to lower or raise synchronously, thus adjusting the soil loosening depth of the multiple primary crushing blade groups 302 and crushing blade groups 303.

[0043] Furthermore, by adjusting the telescopic ends of the electric telescopic rods 403 on both sides to different lengths, the floating plate 401 and the gearbox 301 can present different tilt states. By adjusting the tilt angles of the multiple primary crushing blade groups 302 and the multiple crushing blade groups 303, the multiple primary crushing blade groups 302 and the multiple crushing blade groups 303 can be used to loosen soil in working areas with different slopes, thereby improving the flexibility and adaptability of the soil loosening device.

[0044] Specifically, there are four buffer connectors 402 and four electric telescopic rods 403. Each buffer connector 402 corresponds to one electric telescopic rod 403 and is located at one of the four corners of the floating plate 401. The multiple buffer connectors 402 connect and limit the movement of the floating plate 401 and the electric telescopic rods 403.

[0045] Combination Figure 7 and Figure 8 The buffer connector 402 includes a fixed base 4021, a telescopic connecting block 4022, and multiple sets of buffer springs 4023. The fixed base 4021 is fixedly disposed above the floating plate 401; the telescopic connecting block 4022 is slidably disposed within the fixed base 4021; the multiple sets of buffer springs 4023 are all disposed between the fixed base 4021 and the telescopic connecting block 4022, with both ends of the multiple sets of buffer springs 4023 fixedly connected to the fixed base 4021 and the telescopic connecting block 4022, respectively. The telescopic connecting block 4021 is connected to the telescopic end of the electric telescopic rod 403 through the telescopic connecting block 4022. The telescopic connecting block 4022 and the fixed base 4021 are buffered by compressing the multiple sets of buffer springs 4023, preventing the floating plate 401 from directly transmitting the force to the telescopic end of the electric telescopic rod 403, which could lead to a shortened service life or jamming of the electric telescopic rod 403.

[0046] Specifically, the telescopic connecting block 4022 has a positioning pin hole at one end outside the fixed base 4021, and a connecting pin is inserted into the positioning pin hole. The telescopic end of the electric telescopic rod 403 is hinged to the telescopic connecting block 4022 through the connecting pin. Using a connecting pin to hinge the telescopic end of the electric telescopic rod 403 to the telescopic connecting block 4022 ensures the flexibility of movement and avoids jamming between the telescopic connecting block 4022 and the telescopic end of the electric telescopic rod 403 during operation.

[0047] Combination Figure 1 and Figure 2 The adjustable floating limit assembly 4 also includes multiple limit telescopic rods 404, with a total of four rods. The four limit telescopic rods 404 are arranged in pairs, with two pairs of rods 404 symmetrically positioned on both sides of the floating plate 401. Each limit telescopic rod 404 is hinged at both ends to the floating plate 401 and the frame 1, respectively. The multiple limit telescopic rods 404 provide auxiliary connection between the frame 1 and the floating plate 401, improving the assembly stability of the floating plate 401. Simultaneously, by varying the extension and retraction of the multiple limit telescopic rods 404, the gearbox 301 can synchronously change with the terrain, improving the adaptability of the soil loosening device to different terrains.

[0048] Combination Figure 1 and Figure 2 The limiting telescopic rod 404 includes a fixed outer cylinder 4041, a telescopic inner rod 4042, and a connecting spring 4043. The fixed outer cylinder 4041 is a cylindrical component with one open end, and one end of the fixed outer cylinder 4041 is hinged to the frame 1. The telescopic inner rod 4042 is slidably engaged with the open end of the fixed outer cylinder 4041, and one end of the telescopic inner rod 4042 located outside the fixed outer cylinder 4041 is hinged to the floating plate 401. The connecting spring 4043 is fixedly disposed between the fixed outer cylinder 4041 and the telescopic inner rod 4042. The connecting spring 4043 connects and limits the fixed outer cylinder 4041 and the telescopic inner rod 4042, and the limiting telescopic rod 4044 can elastically connect the floating plate 401 and the frame 1 by means of compression or reset of the connecting spring 4043.

[0049] In practical use, the soil loosening device is moved to the work area. Then, according to the slope and depth requirements of the work area, the extension length of the telescopic ends of multiple electric telescopic rods 403 is adjusted. After adjustment, the gasoline engine 304 is controlled to run, so that the output end of the gasoline engine 304 drives the transmission bevel gear 305 to rotate. The driving gear 308 drives the driven gear 309 to rotate synchronously under the meshing action of the transmission bevel gear 305 and the driven bevel gear 306. The driven gear 309 drives a pair of soil loosening drive gears 311 to rotate, so that a pair of output shafts 310 drive multiple primary crushing blade groups 302 and multiple crushing blade groups 303 to rotate. Thus, the soil loosening treatment of the work area is carried out through the cooperation of multiple primary crushing blade groups 302 and multiple crushing blade groups 303.

[0050] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
