Description

Technical Field

[0001] This utility model relates to the field of micro-tiller technology, and in particular to a multi-functional micro-tiller. Background Technology

[0002] Mini tillers are characterized by their light weight, small size, and simple structure. They are widely applicable to dry land, paddy fields, and orchards in plains, mountains, and hills. Mini tillers can move freely in the fields, making them convenient for users to operate and store. They eliminate the problem of large agricultural machinery being unable to access mountainous fields, making them the best alternative to oxen for farmers.

[0003] However, when using existing mini-tillers, the rotating plow blades cause significant vibrations during tilling, and the impact force between the plow and the ground is directly transmitted to the lifting mechanism, resulting in high wear and tear on these components. Secondly, after tilling, fertilizer or soil conditioner needs to be applied, but existing mini-tillers lack this function, requiring separate fertilizer application after tilling. Therefore, this invention proposes a multi-functional mini-tiller. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a multi-functional micro-tiller.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-functional micro-tiller, including a chassis, an L-shaped support frame fixed to one side of the upper surface of the chassis, a rotary tillage assembly provided below the L-shaped support frame, an electric telescopic rod for driving the rotary tillage assembly to move up and down fixed to the top of the L-shaped support frame, a buffer assembly connected to the bottom telescopic end of the electric telescopic rod and the rotary tillage assembly, a notch opened in the middle of the chassis, a material spreading assembly installed on the upper surface of the chassis and directly above the notch, a battery fixed on the upper surface of the chassis, two front wheels installed on the lower surface of the chassis near the rotary tillage assembly, two rear wheels installed on the lower surface of the chassis away from the front wheels, and a control cabinet and a push handle installed on the upper surface of the chassis near the rear wheels.

[0006] Furthermore, the rotary tillage assembly includes a U-shaped plate, a roller is rotatably connected inside the U-shaped plate, a plurality of plow blades are fixedly connected to the surface of the roller, and a first motor for driving the roller to rotate is fixed to the outer wall of the U-shaped plate.

[0007] Furthermore, two arc-shaped baffles are fixed on both sides of the top of the U-shaped plate.

[0008] Furthermore, the buffer assembly includes a sleeve fixed to the upper surface of the U-shaped plate, a movable rod slidably connected inside the top end of the sleeve, a spring fixedly connected to the bottom end of the movable rod and the bottom wall of the sleeve, and the top end of the movable rod being fixedly connected to the bottom telescopic end of the electric telescopic rod by bolts.

[0009] Furthermore, an inclined reinforcing rod is fixedly connected to the top of the L-shaped support frame.

[0010] Furthermore, the material spreading assembly includes a material storage trough fixed to the upper surface of the vehicle panel. A rectangular feeding pipe is fixedly connected to the bottom end of the material storage trough, and the feeding pipe is located inside the notch. A cylinder is rotatably connected inside the feeding pipe. Several grooves are evenly spaced on the outer wall of the cylinder. A second motor for driving the cylinder to rotate is fixed to the outer wall of the feeding pipe. Two guide plates are fixed to the bottom end of the material storage trough, and the bottom ends of the two guide plates are in contact with the top surface of the cylinder.

[0011] Furthermore, a third motor for driving the rear wheels to rotate is installed on the lower surface of the vehicle body near the rear wheels.

[0013] 1. In use, this utility model is a multi-functional micro-tiller equipped with a vehicle plate, an L-shaped support frame, an electric telescopic rod, a rotary tillage assembly, a buffer assembly, front wheels, rear wheels, and a battery. When using this micro-tiller to till the land, the telescopic rod can be extended to bring the rotary tillage assembly into contact with the soil. When the micro-tiller is moving and tilling the land, the buffer assembly can prevent the force on the rotary tillage assembly from being directly transmitted to the electric telescopic rod, thereby reducing the probability of damage to the rotary tillage part of the micro-tiller and protecting the plow plate of the rotary tillage assembly.

When in use, this utility model is a multi-functional micro-tiller, which is equipped with a material storage trough, a feeding pipe, a cylinder, and a second motor to form a spreading component. The cylinder has several grooves evenly spaced on its surface. The second motor drives the cylinder to rotate at a uniform speed inside the feeding pipe. The grooves can be used to spread fertilizer or soil modifier in the storage trough onto the tilled soil, thereby realizing the multi-functionality of the micro-tiller. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a multi-functional micro-tiller is disclosed, including a platform 1. An L-shaped support frame 2 is fixed to one side of the upper surface of the platform 1. A rotary tillage assembly is provided below the L-shaped support frame 2. An electric telescopic rod 3 for driving the rotary tillage assembly to move up and down is fixed to the top of the L-shaped support frame 2. A buffer assembly is connected to the bottom telescopic end of the electric telescopic rod 3 and the rotary tillage assembly. A notch 101 is opened in the middle of the platform 1. A material spreading assembly is installed on the upper surface of the platform 1 and directly above the notch 101. A battery 23 is fixed on the upper surface of the platform 1. Two front wheels 19 are installed on the lower surface of the platform 1 near the rotary tillage assembly. Two rear wheels 20 are installed on the lower surface of the platform 1 away from the front wheels 19. A control cabinet 22 and a push handle 24 are installed on the upper surface of the platform 1 near the rear wheels 20.

[0024] like Figure 1 As shown, the rotary tillage assembly includes a U-shaped plate 4, a roller 5 is rotatably connected inside the U-shaped plate 4, several plow plates 6 are fixedly connected to the surface of the roller 5, and a first motor 7 that drives the roller 5 to rotate is fixed to the outer wall of the U-shaped plate 4.

[0025] The output shaft of the first motor 7 is fixedly connected to the roller 5. The first motor 7 can drive the roller 5 to rotate inside the U-shaped plate 4, thereby driving several plow plates 6 to rotate. The plow plates 6 can be used to till the land.

[0026] like Figure 1 As shown, two arc-shaped baffles 8 are fixed on both sides of the top of the U-shaped plate 4. The baffles 8 can prevent the soil from splashing everywhere during tilling.

[0027] like Figures 1-2 As shown, the buffer assembly includes a sleeve 9 fixed to the upper surface of the U-shaped plate 4. A movable rod 10 is slidably connected inside the top end of the sleeve 9. A spring 11 is fixedly connected to the bottom end of the movable rod 10 and the inner bottom wall of the sleeve 9. The top end of the movable rod 10 is fixedly connected to the bottom telescopic end of the electric telescopic rod 3 by bolts.

[0028] When the plow plate 6 of the rotary tiller assembly rotates and contacts the ground, the U-shaped plate 4 can bounce up and down along the surface of the movable rod 10 through the sleeve 9, and the spring 11 can act as a buffer. This prevents the rotary tiller assembly from being subjected to an upward force that directly acts on the electric telescopic rod 3, thus protecting the electric telescopic rod 3. Furthermore, because the rotary tiller assembly has upward bouncing travel space, it can also prevent the plow plate 6 from hitting stones in the soil hard, thus protecting the plow plate 6.

[0029] like Figure 1 As shown, an inclined reinforcing rod 12 is fixedly connected to the top of the L-shaped support frame 2. The reinforcing rod 12 is used to enhance the support strength of the L-shaped support frame 2.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the material spreading assembly includes a material storage trough 13 fixed to the upper surface of the vehicle plate 1. A rectangular discharge pipe 14 is fixedly connected to the bottom end of the material storage trough 13, and the discharge pipe 14 is located inside the notch 101. A cylinder 15 is rotatably connected inside the discharge pipe 14. Several grooves 16 are evenly spaced on the outer wall of the cylinder 15. A second motor 17 for driving the cylinder 15 to rotate is fixed to the outer wall of the discharge pipe 14. Two guide plates 18 are fixed to the bottom end of the material storage trough 13. The bottom ends of the two guide plates 18 are in contact with the top surface of the cylinder 15.

[0031] The diameter of the cylinder 15 is the same as the width of the feeding pipe 14, and the output end of the second motor 17 is fixedly connected to the cylinder 15. Therefore, after the cylinder 15 is driven to rotate inside the feeding pipe 14 by the second motor 17, the fertilizer or modifier in the storage tank 13 will be stuck into the groove 16 on the surface of the cylinder 15. When the groove 16 rotates to the bottom, the fertilizer or modifier in the groove 16 is discharged along the feeding pipe 14. The discharge speed of the fertilizer and modifier can be adjusted by controlling the rotation speed of the second motor 17.

[0032] A third motor 21 is installed on the lower surface of the platform 1 near the rear wheel 20 to drive the rear wheel 20 to rotate. The third motor 21 drives the rear wheel 20 to rotate, which can drive the machine to move and provide assistance.

[0033] Working principle: Fertilizer or modifier is added to the storage trough 13. Then, the electric telescopic rod 3 is activated to extend and drive the plow plate 6 of the rotary tiller assembly to contact the soil. Subsequently, the first motor 7 is activated to drive the drum 5 to rotate, and the plow plates 6 on the surface of the drum 5 will rotate synchronously, thus tilling the soil. Next, the third motor 21 is activated to drive the rear wheel 20 to rotate, driving the machine to move. The machine can be moved by holding the push handle 24. At the same time, the second motor 17 is activated to drive the cylinder 15 to rotate inside the discharge pipe 14, so that the fertilizer or modifier in the storage trough 13 rotates along the groove 16 on the outer wall of the cylinder 15 to be discharged below the discharge pipe 14. This machine can till the soil and spread fertilizer at the same time using the rotary tiller assembly, realizing the multi-functionality of the machine.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
