Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery, and in particular to a handlebar for a micro-tiller. Background Technology
[0002] Currently, most of the handrails on mini-tillers produced in my country are fixed welded structures. After assembly, the handrails are not adjustable. As the height of the handrails cannot be adjusted, the handrails cannot meet the different height requirements of operators with different heights.
[0003] Although various structures have been developed in the existing technology to achieve the tilt angle adjustment of the handle, most of them use holes on the blades and a pin to lock them in place. While this locking mechanism is convenient, it has the problem of not being able to adjust to the accurate angle position in practical applications. This makes it impossible for operators to adjust to a suitable angle position, which greatly affects the normal operation of the micro-tiller. Utility Model Content

By incorporating a first adjustment mechanism and a second adjustment mechanism on the handlebar, the vertical and horizontal angles of the handlebar can be freely adjusted. The engagement of the second connecting tooth on the blade mechanism with the first connecting tooth on the first adjustment mechanism allows the minimum adjustment angle of the handlebar to be reduced to 5°-7°. To achieve the above objective, the specific technical solution for this mini-tiller handlebar is as follows: A micro-tiller handlebar includes an angle adjustment mechanism, a blade mechanism, a turntable mechanism, a housing, a rotating mechanism, a limiting mechanism, a handlebar body, and a rotatable bolt.

By the engagement of the second connecting tooth on the fan blade mechanism with the first connecting tooth on the first adjustment mechanism, the angle adjustment of the handlebar body can be adjusted according to the engagement between different connecting teeth. This reduces the minimum adjustment angle of the handlebar body to 5°-7°, making it easier for the operator to select a handlebar height that suits them.

The angle adjustment mechanism includes a first adjustment mechanism 3 and a second adjustment mechanism 2; the first adjustment mechanism 3 cooperates with the blade mechanism 4; the second adjustment mechanism 2 cooperates with the turntable mechanism 8; the first adjustment mechanism 3 cooperates with the limiting mechanism 9; the limiting mechanism 9 is connected to the housing 5; the first adjustment mechanism 3 includes a first adjustment post 31, and the first adjustment post 31 is provided with a first connecting tooth 35; the blade mechanism 4 is provided with a second connecting tooth 41; the first connecting tooth 35 and the second connecting tooth 41 mesh with each other. By incorporating a first adjustment mechanism 3 and a second adjustment mechanism 2 on the handlebars of the micro-tiller, the handlebar body 1 can be freely adjusted in both vertical and horizontal angles. The first adjustment mechanism 3, in conjunction with the blade mechanism 4, can fix the vertical angle of the handlebar body 1. The second connecting tooth 41 on the blade mechanism 4 meshes with the first connecting tooth 35 on the first adjustment mechanism 3, allowing the angle adjustment of the handlebar body 1 to be adjusted according to the meshing between different connecting teeth. This reduces the minimum adjustment angle of the handlebar body 1 to 5°-7°, making it easier for the operator to select a suitable handlebar body 1 height.
[0028] In this embodiment, the angle between two adjacent teeth in the fan blade mechanism 4 and the rotatable bolt is 5°-7°, and preferably 6°. In this embodiment, when the fan blade mechanism 4 is adjusted up or down by one tooth, the position of the handlebar body 1 is simultaneously adjusted up or down by 100mm.
[0029] The first adjusting column 31 in this embodiment is also provided with a limiting groove 34; the limiting mechanism 9 includes a connecting column 91 and a first ball 92, the first ball 92 cooperating with the limiting groove 34. The first adjusting column 31 is also provided with a limiting groove 34, which allows the first adjusting column 31 to limit its own rotation, thereby fixing the angle of the first adjusting column 31. The limiting mechanism 9 includes a connecting column 91 and a first ball 92, which can cooperate with each other. The connecting column 91 is threaded to the housing 5. By tightening and loosening the connecting column 91, the contact distance between the first ball 92 and the limiting groove 34 can be adjusted. The first ball 92 can cooperate with the limiting groove 34 in a sliding or rolling manner. In essence, the connecting column 91 limits the position of the first ball 92, and the first ball 92 limits the position of the limiting groove 34. That is, the limiting mechanism 9 limits the rotation angle of the first adjusting column 31 in the first adjusting mechanism 3, preventing the rotation angle from shifting during the angle adjustment process.

The first adjustment mechanism 3, including the first elastic component 33, the first cable component 32, and the first connecting member 36, enables the first adjustment mechanism 3 to adjust the vertical angle through the first elastic component 33, the first cable component 32, the first connecting member 36, and the first connecting post 91; the first elastic component 33 cooperates with the first adjusting post 31 through its own elastic force. After the first elastic component 33 contracts, it releases its own elastic force while pushing the first adjusting post 31 to engage with the fan-shaped mechanism 4, thereby achieving adjustment and control of the vertical angle; through the first... A cable component 32 is connected to the first adjusting column 31, so that when the first adjusting column 31 is in use, it can be pulled by the first cable component 32 to overcome the elastic force of the first elastic component 33, thereby disengaging from the fan blade mechanism 4, so that the fan blade mechanism 4 can be adjusted in angle; the first connector 36 cooperates with the first elastic component 33 and is connected to the housing 5, so that the elastic tendency of the first elastic component 33 can be controlled by the first connector 36, so that the magnitude of the adjusting pull of the first adjusting mechanism 3 can be adjusted by the first connector 36.

The second adjustment mechanism 2 includes a second adjustment post 21, a second elastic component 22, a second cable component 24, and a second connector 23, enabling the second adjustment mechanism 2 to adjust the lateral angle via the second adjustment post 21, the second elastic component 22, the second cable component 24, and the second connector 23. The turntable mechanism 8 has a limiting hole 81; the second adjustment post 21 cooperates with the limiting hole 81, allowing the second adjustment mechanism 2 and the turntable mechanism 8 to cooperate through the limiting hole 81 on the turntable mechanism 8 and the second adjustment post 21 in the second adjustment mechanism 2, thereby adjusting and fixing the lateral angle of the handlebar body 1. The second elastic component 22 cooperates with the second adjustment post 21, allowing the second adjustment post 21 to cooperate with the second elastic component 22, enabling the second elastic component 22 to... After contraction, the release of elastic force pushes the second adjusting column 21 towards the limiting hole 81, thereby achieving lateral angle adjustment. The second cable component 24 is connected to the second adjusting column 21, allowing the second adjusting column 21 to disengage from the turntable mechanism 8 and rotate laterally when lateral angle adjustment is needed, thus achieving different angle adjustments. The second connecting member 23 cooperates with the second elastic component 22 and is connected to the housing 5, allowing the second connecting member 23 to compress the second elastic component 22, causing it to contract. Alternatively, the second connecting member 23 can be threaded into the housing 5, allowing it to adjust the elastic tendency of the second elastic component 22.

The housing 5 has a first connecting hole 51, through which it is rotatably connected to the rotating mechanism 10. This allows the handlebar body 1 to rotate laterally, enabling the selection of the lateral angle. The housing 5 also has a second connecting hole 52, through which it is connected to a second adjusting mechanism 2. This allows the second adjusting mechanism 2 to be fixed in position within the second connecting hole 52. The housing 5 also has a third connecting hole 53, through which it is connected to a first adjusting mechanism 3. This allows the first adjusting mechanism 3 to be fixed in position within the housing 5. Finally, the housing 5 has a fourth connecting hole 54, through which it is connected to a limiting mechanism 9. This allows the limiting mechanism 9 to be fixed in position within the housing 5.
[0033] In this embodiment, the handlebar body 1 is movably connected to the housing 5 via a rotatable bolt 6. This rotatable bolt 6 allows the handlebar body 1 to be connected to the housing 5 as well as to the handlebar body 1, thus enabling adjustment of the vertical angle of the handlebar body 1.

The first rotating column 1001 is connected to the turntable mechanism 8. The second ball bearing 1002 cooperates with the first rotating column 1001. The housing 5 is provided with a fifth connecting hole 55. The housing 5 is connected to the plunger 1003 through the fifth connecting hole 55. The rotating mechanism 10, including the first rotating column 1001, the second ball bearing 1002, and the plunger 1003, allows the rotating mechanism 10 to be rotatably connected to the housing 5 via the second ball bearing 1002 on the first rotating column 1001, while the plunger 1003 restricts the second ball bearing 1002 to prevent it from flowing out. The first rotating column 1001 is fixedly connected to the turntable mechanism 8, so that when the housing 5 rotates around the first rotating column 1001, it also rotates around the turntable mechanism 8, thereby achieving a lateral angle adjustment. The adjustment is achieved by the second ball bearing 1002 cooperating with the first rotating column 1001, allowing the second ball bearing 1002 to roll around the first rotating column 1001, thus realizing the rotational connection between the rotating mechanism 10 and the housing 5; the housing 5 is provided with a fifth connecting hole 55; the housing 5 is connected to the plunger 1003 through the fifth connecting hole 55, so that the plunger 1003 can be connected to the housing 5 through the fifth connecting hole 55, and the second ball bearing 1002 is also installed in the rotating mechanism 10 through the fifth connecting hole 55.

The bearing 1005 is connected to the second rotating column 1004 and to the housing 5. By including the second rotating column 1004 and the bearing 1005, the rotating mechanism 10 can be rotatably connected to the housing 5 by mounting the bearing 1005 on the rotating column, thereby enabling the handlebar body 1 to rotate around the turntable mechanism 8, i.e., adjusting the lateral angle. The connection between the second rotating column 1004 and the turntable mechanism 8 also allows for a fixed connection between the second rotating column 1004 and the turntable mechanism 8, thus enabling the housing 5 to rotate around the turntable mechanism 8. The connection between the bearing 1005 and the second rotating column 1004, and the bearing 1005 to the housing 5, means that the bearing 1005 mounted on the second rotating column 1004 is also simultaneously connected to the housing 5. In other words, the rotating mechanism 10 achieves a rotatable connection with the housing 5 through the bearing 1005.
[0036] The handlebars of this embodiment of the micro-tiller also include a rotatable bolt 6, which is connected to the housing 5.

The rotatable bolt 6, connected to the housing 5, provides a fixed connection between the rotatable bolt 6 and the housing 5, allowing the rotatable bolt 6 to be fixed to the housing 5. The connecting part 61 and the rotating part 62 of the rotatable bolt 6 connect the rotatable bolt 6 to the housing 5, and the rotating part 62 engages with the handlebar body 1 to achieve a rotatable connection between the handlebar body 1 and the housing 5. The housing 5 is connected to the connecting part 61 through the sixth connecting hole 56, allowing the connecting part 61 of the rotatable bolt 6 to be connected to the housing 5 through the sixth connecting hole 56.
[0037] The handlebars of this embodiment also include a protective shell 11, which is connected to a rotatable bolt 6. By including a protective shell 11 on the handlebars, and connecting it to the rotatable bolt 6, a protective shell 11 is provided on the outer surface of the handlebars to protect corresponding components on the handlebar body 1. This protective shell 11 is fixed to the handlebars by the rotatable bolt 6.

[0045] Locking phase (tooth engagement + ball bearing limit): Operation action: The user releases the first cable component 32.
[0046] Institutional Response: The first elastic component 33 releases its elastic force, pushing the first adjusting column 31 forward, forcing the first connecting tooth 35 to engage with the groove of the closest second connecting tooth 41 of the fan mechanism 4.
[0047] Under the pressure of the connecting column 91, the first ball 92 of the limiting mechanism 9 is inserted into the limiting groove 34 of the first adjusting column 31, forming a mechanical lock. That is, the circumferential rotation of the first adjusting column (31) is restricted.
[0048] Thread fine adjustment: Rotating the connecting column 91 can change its pressure on the first ball 92 to adapt to different load requirements.
[0049] II. Lateral Angle Adjustment System (Horizontal Rotation) Core components: Second adjustment mechanism 2, turntable mechanism 8, rotating mechanism 10, housing 5 Detailed workflow: Unlocking phase (disengaging from the positioning hole): Operation action: The user pulls the second cable component 24.
[0050] Institutional Response: The cable pulls the second adjusting column 21 to overcome the elastic force of the second elastic component 22 and retracts backward.
[0051] The tip of the adjusting column is completely withdrawn from the current limiting hole 81 of the turntable mechanism 8.
[0052] Angle adjustment phase: Operation action: The user rotates the handlebar body 1 horizontally.
[0053] Institutional Response: The housing 5 rotates around the rotating mechanism 10 through the first connecting hole 51: Option A (ball bearing type): The second ball bearing 1002 rolls along the annular raceway of the first rotating column 1001.

[0055] The turntable mechanism 8 is fixed (connected to the main body of the micro-tiller), and multiple limiting holes 81 are evenly distributed around its circumference.
[0056] Locking stage (insertion of positioning hole): Operation action: The user releases the second cable component 24.
[0057] Institutional Response: The second elastic component 22 pushes the second adjusting column 21 forward, and the conical tip automatically aligns with the nearest limiting hole 81 and is inserted.
[0058] Anti-loosening adjustment: Tightening the second connecting piece 23 (adjusting bolt) can increase the spring preload and ensure no shaking under heavy load conditions.
[0059] This invention, by incorporating a first adjustment mechanism 3 and a second adjustment mechanism 2 on the handlebars of a micro-tiller, allows for arbitrary adjustment of the vertical and horizontal angles of the handlebar body 1. The first adjustment mechanism 3, in conjunction with the blade mechanism 4, can fix the vertical angle of the handlebar body 1. By engaging the second connecting tooth 41 on the blade mechanism 4 with the first connecting tooth 35 on the first adjustment mechanism 3, the angle of the handlebar body 1 can be adjusted according to the engagement between different connecting teeth. This reduces the minimum adjustment angle of the handlebar body 1 to 5°-7°, making it easier for the operator to select a suitable handlebar body 1 height.
