Description

Technical Field

[0001] The invention relates to a micro-tillage device, in particular to a vibration-reducing micro-tillage device. Background Art

[0002] With the progress of social science and technology and the development of agricultural economy, the level of agricultural mechanization has been greatly improved. However, due to the requirements of human resources and working environment, micro-tillage equipment is popular among users because of its convenience and multi-functional configuration. Micro-tillage equipment consists of a micro-tillage machine frame, power assembly, gearbox, walking mechanism, implements, handrail frame assembly, protection assembly, connecting frame, and resistance rod. It is powered by a small gasoline engine, a small diesel engine, and a small electric motor. On the output shafts on the left and right sides of the walking box, implements are installed to complete the work. There is a control device on the handrail frame to facilitate the operation of the micro-tillage machine.

[0003] However, the current micro-tillage machines have poor vibration reduction effects when in use. The micro-tillage machines vibrate with large amplitude and high frequency during tillage. Long-term operation will cause the operator's hands to become numb and weak due to the vibration of the armrests. In addition, it is inconvenient for the operator to control the machine under high-frequency vibration, making the operation troublesome. Summary of the invention

[0004] One object of the present invention is to provide a vibration-damping micro-tillage device, which improves the vibration reduction effect through the interaction between the moving wheel and the vibration-damping component, buffers the force between the operator and the device, and improves the use efficiency.

[0005] This purpose is achieved by adopting the following technical solutions:

[0006] The device includes a frame, a power structure and a handle structure arranged on the frame, on this basis, a first connecting rod is arranged on the frame, and the two ends of the first connecting rod are respectively connected to a moving wheel and a vibration reduction assembly corresponding to the moving wheel, and two moving wheels are arranged on the first connecting rod of the device, and the two moving wheels correspond to the two vibration reduction assemblies one by one. The device is connected with the moving wheel by the vibration reduction assembly, and the moving wheel can support the device and reduce the hand force of the operator. At the same time, the moving wheel buffers part of the force generated by the power structure through the force between the moving wheel and the ground, and the other part is buffered by the vibration reduction assembly connected thereto, and the force of the power structure is further released through the vibration reduction assembly to reduce the force on the operator.

[0007] The device arranges a vibration reduction component on the first connecting rod, and the moving wheel is also arranged on the first connecting rod. The vibration reduction component and the moving wheel contact and interact with each other. During the use of the device, the power structure on the frame works to drive the frame to vibrate. During the vibration process, the frame drives the vibration reduction component and the moving wheel on the first connecting rod to vibrate together. A part of the force of the moving wheel is consumed by contact with the ground, and another part of the force of the moving wheel is consumed by the vibration reduction component. The three act on each other in a cycle, and most of the force is consumed by the vibration reduction component, so as to avoid the release of the force through the handle structure, thereby reducing the force at the handle structure from the position structure; finally, the force is further consumed through the interaction between the vibration reduction component and the moving wheel, and finally the force is consumed at the vibration reduction component.

[0008] On this basis, the shock absorbing assembly of the device includes a first buffer rod, a second buffer rod, a third buffer rod, a fourth buffer rod and a first spring connected between the first buffer rod and the second buffer rod. The third buffer rod and the second buffer rod are both movably connected to the fourth buffer rod, and a block is provided on the fourth buffer rod; a second connecting rod is connected to the moving wheel, and the second connecting rod is connected to an action wheel provided with an action block. The action block or the action wheel can act on the block, so that the fourth buffer rod drives the first spring to extend and retract.

[0009] When this component is in use, the action block or the action wheel contacts the stopper on the fourth buffer rod respectively. The sizes of the action block and the action wheel are different. Therefore, when the action block and the action wheel act on the stopper, the stopper drives the fourth buffer rod to move up and down or rotates with the connection between the fourth buffer rod and the third buffer rod as a fulcrum. During the rotation or movement of the fourth buffer rod, the second buffer rod movably connected to it is driven to move up and down, thereby compressing or stretching the first spring between the second buffer rod and the first buffer rod. The first spring realizes force buffering when compressed or stretched. When the power structure is working, the first connecting rod is subjected to the force to shake, and the first connecting rod drives the first buffer rod to move up and down. The first buffer rod generates a first force on the first spring during the movement. At the same time, during the use of this device, the moving wheel drives the action wheel and the action block to rotate. Therefore, in the process of the first spring generating the first force, the action wheel and the action block respectively contact with the block, and the block drives the second buffer rod to generate a second force on the first spring. Since the action wheel and the action block are of different sizes, the distances and positions that the two respectively drive the block to move are also different. Therefore, under the action of the action wheel and the action block, the second force changes repeatedly, and the first force and the second force interact and consume each other on the first spring, thereby buffering the device.

[0010] At the same time, the vibration reduction component of the device is connected to the moving wheel, and the moving wheel is connected to the first connecting rod. The force of the power structure is buffered on the vibration reduction component, the moving wheel and the first connecting rod. The force can be released through the action of the first spring, thereby improving the vibration reduction effect and reducing the vibration amplitude of the micro-tiller.

[0011] Preferably, the third buffer rod of the device is parallel to the first connecting rod, and the first connecting rod is connected to the action rod. If the action rod in the device is fixedly connected to the first connecting rod, the third buffer rod and the first connecting rod cannot move relative to each other. When the fourth buffer rod is under the action of the action block or the action wheel, the fourth buffer rod rotates with the connection between it and the third buffer rod as a fulcrum, thereby driving the second buffer rod to move up and down. In the process of the second buffer rod moving up and down, the first spring is compressed or stretched, thereby releasing the force applied to this structure.

[0012] Preferably, the action block is cocentric with the action wheel, and the radius of the action block is smaller than the radius of the moving wheel. The action block and the action wheel do not contact the ground, and serve as a contact bridge between the moving wheel and the second buffer rod, further improving the buffering efficiency. The action block is cocentric with the action wheel, and the moving wheel drives the action wheel to rotate. When rotating to the action block, the action block and the vibration reduction assembly contact each other. When the action block leaves, the action wheel and the vibration reduction assembly contact each other, thereby driving the fourth buffer rod to move up and down or rotate, thereby generating a second action force. The first action force and the second action force are further consumed through the movement of the fourth buffer rod. This structure can make the action force more self-consumed inside the vibration reduction device, thereby improving the use efficiency.

[0013] If the upper end of the action rod of the device passes through the first connecting rod, and the action rod can move up and down on the first connecting rod, the third buffer rod and the first connecting rod can move relatively, and when the fourth buffer rod is acted upon by the action block or the action wheel, the fourth buffer rod can not only move up and down, but also rotate with its connection with the third buffer rod as a fulcrum, thereby further improving the buffering effect.

[0014] Compared with the existing vibration reduction device, the first buffer rod, the second buffer rod and the first spring thereon of the present device are mainly used as the force release points, and the moving wheel drives the acting wheel to rotate together. When there is vibration, part of the force of the moving wheel is released by contacting with the ground, and the other part is transmitted to the fourth buffer rod through the acting wheel for release, and the vibration reduction device of the present device is connected to the first connecting rod. Therefore, most of the vibration force of the present device is released between the first connecting rod and the moving wheel, and a very small part is transmitted to the handle, thereby improving the vibration reduction effect.

[0015] Furthermore, in order to further alleviate the vibration force between the handle structure and the power structure, an adjustment mechanism is connected between the first connecting rod and the handle structure of the device, and the adjustment mechanism includes a first adjustment rod and a second adjustment rod that are hinged to each other, and a second spring is connected between the first adjustment rod and the second adjustment rod. The first adjustment rod is movably connected to the first spring rod, and the second adjustment rod is movably connected to the second spring rod, and the second spring is sleeved on the first spring rod and the second spring rod. Vibration reduction is performed between the handle and the first connecting rod through the first adjustment rod, the second adjustment rod and the second spring therebetween, so as to further buffer the force applied to the handle. At the same time, the second adjustment rod is movably connected to the first connecting rod, and the first adjustment rod is movably connected to the handle structure. The second adjustment rod is connected to the upper end face of the first connecting rod, and the second adjustment rod can rotate on the plane where the upper end face of the first connecting rod is located. Therefore, the handle can be rotated left and right during use, and vibration reduction does not affect the use.

[0016] The second adjusting rod is movably connected with the first connecting rod, and the first adjusting rod is movably connected with the handle structure. The handle structure is subjected to the force when the power mechanism is working, and is further buffered by the second spring between the first adjusting rod and the second adjusting rod. The second adjusting rod and the first adjusting rod connect the handle and the first connecting rod to each other.

[0017] Preferably, the first connecting rod is connected to the moving wheel via a vibration damping rod. A spring is sleeved on the vibration damping rod. An airbag is sleeved on the spring, and the two ends of the spring are respectively connected to the inner top and inner bottom of the airbag. Since the vibration damping rod is in a vertical state, the spring and the airbag are arranged on the vibration damping rod to further reduce vibration and buffer between the first connecting rod and the moving wheel, thereby improving the use efficiency.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] The present invention discloses a vibration-damping micro-tillage device. A vibration-damping component and a moving wheel are added to a frame of the device. The vibration-damping component and the moving wheel are connected and interact with each other. The vibration force generated by a power mechanism at the front end of the frame is transferred to the rear end of the frame through the frame. A part of the force is released through the contact between the moving wheel and the ground. The vibration-damping component is connected between the moving wheel and a first connecting rod. The force between the moving wheel and the frame is consumed by the vibration-damping component between the two. The two interact with each other, so that the force is consumed between the moving wheel and the frame, and the force at the handle structure is further reduced, thereby improving the use efficiency.

[0020] At the same time, further vibration reduction optimization is performed between the handle structure and the first connecting rod through the first adjusting rod, the second adjusting rod and the second spring therebetween.

[0021] Secondly, after the device is provided with moving wheels, compared with the existing structure, the center of the device moves backward, and the operator does not need to exert too much force on the handle structure. When pushing, it can be pushed by directly providing a forward force, and the vibration force is consumed at the bottom of the handle, that is, the vibration reduction component, further improving the vibration reduction efficiency and the use efficiency.
