Description

Technical Field

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

[0002] Soil loosening is a crucial step in landscaping maintenance. It breaks up soil compaction, increases soil aeration and water permeability, and promotes plant root growth and development. Existing landscaping soil loosening equipment mostly uses a single rotary tiller shaft. While it can accomplish the task to some extent, its structural limitations are becoming increasingly apparent when facing increasingly complex urban greening environments.

[0003] Current soil loosening equipment typically only has one fixed loosening mode and cannot classify soil according to its compaction level. For example, when dealing with soil that has a hard surface but requires fine loosening of the subsoil, a single blade often struggles to balance crushing force and loosening, resulting in poor loosening effects. More importantly, the loosening depth adjustment mechanisms of existing equipment are usually rudimentary, often requiring manual adjustment of the wheel axle height or limit pins after the machine has stopped. This operation is cumbersome, time-consuming, and labor-intensive, and cannot be adjusted in real time and flexibly according to terrain undulations or soil conditions during operation. This not only reduces work efficiency but also easily leads to equipment overload or incomplete loosening due to improper depth control. In addition, existing equipment lacks effective integrated methods to deal with the dust problem generated during operation.

[0004] Therefore, this utility model proposes a soil loosening device for landscaping to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in existing landscaping soil loosening equipment, such as the single loosening mode leading to poor treatment effect on compacted soil, and the rigid working depth adjustment structure resulting in low work efficiency and poor adaptability, this utility model aims to provide a landscaping soil loosening device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a soil loosening device for landscaping, comprising: a shell, a wheel rotatably connected to the bottom of the shell, and a handle fixed to the outer wall of one side of the shell; as well as a first motor, shovel teeth, an electric push rod, a transmission handle, a protective shell, a second motor, a gear reducer, a loosening roller, and a water tank.

[0007] The electric push rod, the transmission handle, and the loosening roller constitute a fine loosening mechanism with dynamically adjustable depth, and the shovel teeth constitute a primary crushing mechanism.

[0008] Furthermore, the first motor is fixedly connected inside the outer casing, and its output drives the shovel teeth to rotate via a transmission wheel and belt. A support base is fixedly connected to the bottom surface inside the outer casing, and the electric push rod is fixedly mounted on the top of the support base. A rotating rod is rotatably connected between the inner walls of the outer casing, and a transmission handle is fixedly sleeved on the outside of the rotating rod. The telescopic end of the electric push rod is hinged to the bottom surface of the transmission handle. A protective shell is fixedly connected to the end of the transmission handle away from the rotating rod. The second motor and the gear reducer are fixedly installed inside the protective shell, and the output end of the gear reducer is connected to the loosening roller. A water tank is fixedly mounted on the top of the outer casing, and a spray assembly is connected to the water tank. Through this structure, an organic combination of coarse loosening and adjustable-depth fine loosening is achieved.

[0009] Preferably, the spray assembly has more specific structural details. The spray assembly includes a water pump fixedly installed on one side of the water tank. The water pump's input end is connected to the water tank, and the water pump's output end is fixedly connected to a water supply pipe. The end of the water supply pipe away from the water pump is connected to multiple nozzles, which are fixedly installed on the top of the housing and facing forward. This design ensures that the water source can be pressurized and precisely atomized and sprayed onto the loosened soil area, effectively suppressing dust.

[0010] Preferably, the landscaping soil loosening device further includes a baffle plate, which is disposed inside the housing and located between the wheel and the shovel teeth. The baffle plate extends downward at an angle from the bottom of the housing to block splashed soil and gravel when the shovel teeth are operating at high speed, thereby protecting the safety of the rear mechanism and personnel.

[0011] Preferably, the drive structure within the protective shell consists of dual power sources. Two second motors are symmetrically arranged inside the protective shell, and a gear reducer is positioned between the two second motors. The gear reducer includes a driving gear fixed to the output shafts of the two second motors, and a driven gear set meshing with the driving gear. The driven gear set is fixedly connected to the loosening roller. This dual-motor drive combined with gear reduction significantly increases the torque of the loosening roller, enabling it to handle harder soil without easily getting stuck.

[0012] Preferably, the loosening roller consists of multiple parallel rollers, each roller having helical crushing teeth on its outer surface, and the loosening roller is located below the protective shell. The helical crushing tooth design facilitates continuous cutting of the soil during rolling, reducing operational resistance and improving the fineness of soil crushing.

[0013] Preferably, the transmission handle has an arc-shaped plate structure, with one end sleeved on the rotating rod and the other end fixedly connected to the top of the protective shell, and the width of the transmission handle is adapted to the width of the protective shell. The arc design optimizes the lever arm structure, making the electric actuator swing more smoothly, while the adapted width ensures the stability of the connection.

[0014] Preferably, the side wall of the outer casing has a notch for the shovel teeth to rotate, allowing the shovel teeth to extend out of the bottom surface of the outer casing to perform operations as the drive wheel rotates. This notch design ensures that the shovel teeth have sufficient working stroke to dig deep underground.

[0015] Preferably, the support base is wedge-shaped and fixed to the rear end of the bottom surface inside the housing. The rotating rod is located above the support base and its two ends are connected to the inner wall of the housing through bearing seats. The wedge-shaped structure provides an optimized installation angle for the electric actuator, and the rotating rod supported by the bearing seats ensures the smoothness and accuracy of the entire adjustment mechanism's movement.

[0016] This utility model has the following beneficial effects: 1. This utility model features a dual soil loosening structure, which uses a first motor to drive shovel teeth for initial crushing and a second motor to drive loosening rollers via a gear reducer for fine loosening. This solves the problem that existing soil loosening equipment has a single function and cannot simultaneously achieve both strong crushing of compacted hard soil and fine soil structure adjustment. It achieves the goal of breaking up compacted soil first and then loosening it finely, significantly improving the quality and efficiency of soil treatment in landscaping.

[0017] 2. This utility model, by setting up a depth adjustment mechanism consisting of an electric push rod, a transmission handle, and a rotating rod, utilizes the linear extension and retraction of the electric push rod to drive the transmission handle to swing around the rotating rod, thereby driving the protective shell and the loosening roller below to rise and fall. This solves the problems of existing loosening devices having fixed working depths or requiring laborious adjustment, and being unable to adapt to different soil hardness and working requirements. It achieves the technical effect of being able to flexibly and accurately control the loosening depth and enhance the device's adaptability to different working environments.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0021] Please refer to Figures 1 to 4 This utility model provides a soil loosening device for landscaping, which aims to solve the structural defects of existing soil loosening equipment, such as inconvenience in adjusting the loosening depth, difficulty in dealing with compacted soil with a single loosening mode, and environmental pollution caused by dust during operation.

[0022] like Figure 1 and Figure 2 As shown, the soil loosening device for landscaping includes an outer shell 1 and wheels 3 rotatably connected to the bottom of the inner shell 1. A handle 2 is fixedly connected to one side of the outer wall of the outer shell 1. The outer shell 1 serves as the main support and protective structure of the entire device, and its interior forms a cavity for installing the drive components. The wheels 3 are symmetrically distributed on both sides of the bottom of the outer shell 1 and are rotatably connected through bearings or shafts to support the weight of the device and enable the device to move on the working ground. The handle 2 is fixed to the tail of the outer shell 1, making it convenient for the operator to hold and push the device forward or adjust the direction of travel.

[0023] To achieve initial breaking of the hard surface soil, a first motor 17 is fixedly connected inside the outer shell 1. The first motor 17 serves as a primary power source, and its output shaft extends through the side wall of the outer shell 1 to the outside and is fixedly connected to a transmission wheel 4. Another transmission wheel 4 is rotatably connected to the same side of the outer wall of the outer shell 1. The two transmission wheels 4 are connected by a transmission belt 5, which is used to buffer the impact load. Several shovel teeth 7 are fixedly connected to the outer circumferential surface of the transmission wheel 4 away from the first motor 17. A notch is opened at the lower edge of the side wall of the outer shell 1 to allow the shovel teeth 7 to rotate. When the first motor 17 is started, it drives the active transmission wheel 4 to rotate, and drives the driven transmission wheel 4 with shovel teeth 7 to rotate at high speed via the transmission belt 5. This allows the shovel teeth 7 to periodically extend out of the bottom surface of the outer shell 1 and cut into the soil, using rotational cutting force to break the hardened surface soil.

[0024] Furthermore, to prevent flying debris or soil from damaging the walking mechanism or injuring personnel during operation, a baffle 6 is rotatably connected inside the outer shell 1 and located between the wheel 3 and the shovel teeth 7. The baffle 6 has a plate-like structure and extends downwards from the bottom of the outer shell 1. The position of the baffle 6 can effectively block debris raised by the shovel teeth 7. At the same time, the rotatable connection allows the baffle 6 to deflect and avoid larger obstacles. A water tank 8 is fixedly installed on the top plane of the outer shell 1. The water tank 8 serves as a liquid storage container for the spray system, providing water support for subsequent dust suppression operations. Its position makes reasonable use of the space on the top of the outer shell 1 and does not affect the movement of other mechanical parts.

[0025] To address the technical problem that a single depth cannot meet the needs of different soil conditions, this landscaping soil loosening device also includes an adjusting support component and a swing transmission component. Furthermore, the adjusting support component and the swing transmission component form a specific hinged connection, thereby enabling flexible adjustment of the working depth of the subsequent fine soil loosening mechanism.

[0026] Please refer to the following carefully. Figure 1 and Figure 3 A support base 13 is fixedly connected to the bottom surface of the inner shell 1 and behind the shovel teeth 7. The support base 13 has a wedge-shaped block structure and provides a stable installation base for the adjustment mechanism. An electric push rod 14 is fixedly installed on the top of the support base 13. The electric push rod 14 serves as the active drive source for depth adjustment and has an output shaft that can extend and retract in a straight line. A rotating rod 18 is rotatably connected between the inner walls of the outer shell 1 and above the support base 13 through a bearing seat. The rotating rod 18 spans the inner space of the outer shell 1 and serves as the rotation fulcrum for the swinging action. A transmission handle 12 is fixedly sleeved on the outer circumferential surface of the rotating rod 18. The transmission handle 12 is an arc-shaped plate-like component with a certain lever arm length.

[0027] In the assembled state, the telescopic end of the electric push rod 14 is connected to the bottom surface of the transmission handle 12 by a hinge. This hinge connection converts the linear reciprocating motion of the electric push rod 14 into the rotational swing of the transmission handle 12 around the axis of the rotating rod 18. The end of the transmission handle 12 away from the rotating rod 18 is fixedly connected to a protective shell 15. The protective shell 15 has an inverted U-shaped or semi-enclosed structure, and its interior forms an installation cavity for accommodating the fine soil loosening drive component. By controlling the telescopic extension of the electric push rod 14, the transmission handle 12 is driven to move the protective shell 15 up and down and swing, thereby precisely controlling the depth of the working component installed below the protective shell 15 into the soil, realizing an adjustable soil loosening operation mode.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to effectively reduce dust pollution generated during soil loosening operations and improve the working environment, the spraying assembly specifically includes a water pump 9 fixedly installed on the outer wall of one side of the water tank 8. The input end of the water pump 9 directly penetrates the wall of the water tank 8 and communicates with its internal water storage chamber. The output end of the water pump 9 is fixedly connected to a water supply pipe 10. The water supply pipe 10 extends forward along the top surface of the outer shell 1. The end of the water supply pipe 10 away from the water pump 9 is branched and connected to a plurality of linearly arranged nozzles 11. The nozzles 11 are fixedly installed at the front edge of the top of the outer shell 1, and the nozzles of the nozzles 11 face the area below and in front of the outer shell 1 so that the water mist sprayed during operation can accurately cover the area of ​​soil that has just been turned over.

[0029] As another preferred embodiment, in order to provide a strong and stable power drive for the loosening roller 16 to perform fine crushing, the internal space of the protective shell 15 is fully utilized and two second motors 20 are symmetrically arranged. The gear reducer 19 is compactly arranged between the two second motors 20. The gear reducer 19 is specifically constructed to include a driving gear fixed on the output shaft of the two second motors 20 respectively, and a driven gear set that maintains a meshing transmission state with the two driving gears at the same time. The output shaft of the driven gear set extends downward and is fixedly connected to the central shaft of the loosening roller 16 below. Through the dual motor drive and gear reduction and torque amplification, it is ensured that the loosening roller 16 has sufficient crushing force when encountering hard soil blocks and is not easy to jam.

[0030] In another preferred embodiment, in order to enhance the cutting and breaking ability of compacted soil and prevent soil adhesion, the loosening roller 16 is designed as an assembly composed of multiple parallel rollers. The outer circumferential surface of each roller is integrally formed or welded with spirally distributed breaking teeth. The spiral structure helps to continuously cut into the soil during rolling and guide the broken soil to the side or rear. The loosening roller 16 is located directly below the protective shell 15, which provides overhead and lateral protection to prevent soil from being drawn into the motor area.

[0031] In addition, in order to optimize the mechanical performance and installation stability of the mechanical transmission structure, the transmission handle 12 adopts an arc-shaped plate structure. This shape design can effectively avoid the movement space of other internal components while meeting the length of the transmission arm. One end of the transmission handle 12 is fixedly sleeved on the rotating rod 18 by key connection or welding, and the other end is fixedly connected to the top plane of the protective shell 15 by bolts. The width of the transmission handle 12 is adapted to the width of the protective shell 15 to distribute the force. The support base 13 is designed as a wedge-shaped block structure and fixed at the rear end of the bottom surface inside the outer shell 1. The wedge-shaped inclined surface provides a suitable installation angle for the electric push rod 14. The rotating rod 18 is located above the support base 13, and its two ends are supported by bearing seats embedded in the inner wall of the outer shell 1 to achieve smooth rotation.

[0032] Finally, in order to cooperate with the rotation of the shovel teeth 7 and prevent splashes from damaging the internal walking mechanism, a notch is provided on the side wall of the outer shell 1 below the transmission wheel 4 for the shovel teeth 7 to rotate through, ensuring that the shovel teeth 7 can smoothly extend out of the bottom surface of the outer shell 1 and penetrate into the soil layer when the transmission wheel 4 rotates to the lowest point; a rotating shaft is arranged horizontally inside the outer shell 1 between the wheel 3 and the shovel teeth 7, and the upper end of the baffle 6 is fitted onto the rotating shaft to achieve a rotatable connection. The baffle 6 extends downward at an angle and passes through the bottom of the outer shell 1, and is held in the blocking position by its own weight or by adding a torsion spring. When encountering a large protruding obstacle on the ground, it can swing backward to avoid it.

[0033] Working principle: When loosening soil is required, the operator holds the handle 2 and pushes the outer shell 1. The wheels 3 are used to roll the device to the designated work area. The first motor 17 inside the outer shell 1 is started. The first motor 17 drives the active transmission wheel 4 to rotate. Through the transmission belt 5, the driven transmission wheel 4 and the shovel teeth 7 rotate at high speed. The shovel teeth 7 then periodically extend out of the bottom surface of the outer shell 1 and forcefully cut into the soil, initially breaking and turning over the severely compacted surface soil. During this process, the baffle 6 blocks and guides the splashed soil and gravel to prevent them from interfering with the operation of the rear components or flying out and injuring people.

[0034] Immediately or simultaneously, the second motor 20 inside the protective shell 15 is started. The second motor 20 drives the loosening roller 16 to rotate after being reduced in speed and increased in torque by the gear reducer 19. The spiral crushing teeth on the surface of the loosening roller 16 are used to perform secondary fine grinding and loosening of the soil after the initial treatment by the shovel teeth 7. If it is necessary to adjust the loosening depth to adapt to different soil types or operation requirements, the electric push rod 14 on the support base 13 is controlled to move. The output end of the electric push rod 14 extends and retracts, and pushes the transmission handle 12 to deflect and swing around the axis of the rotating rod 18. This causes the protective shell 15 connected to the transmission handle 12 and the loosening roller 16 below to change their height position in the vertical direction, thereby accurately setting the depth of the loosening roller 16 into the soil and achieving a controllable operation effect.

[0035] Meanwhile, in order to reduce dust, the water pump 9 next to the water tank 8 is started. The water pump 9 draws water from the water tank 8 and pressurizes it to be transported to the water pipe 10. Finally, the water is atomized and sprayed out by the nozzle 11 at the front end of the outer shell 1. The water mist covers the working area and settles the dust that has just been turned up by the shovel teeth 7 and the loosening roller 16. Through the coordinated action of the above-mentioned multiple mechanisms, the device efficiently completes the integrated landscaping soil treatment process from coarse crushing and fine loosening to dust reduction.

[0036] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
