Description

Technical Field

[0001] This invention relates to the field of tillage equipment technology, and in particular to a handle control mechanism for a micro tiller. Background Technology

[0002] Mini tillers are powered by small diesel or gasoline engines and 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. Equipped with appropriate implements, they can perform tasks such as pumping water, generating electricity, spraying pesticides, and watering. They can also tow trailers for short-distance transport. 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] In the present technology, mini tillers are generally operated by handlebars. In order to control the power of the mini tiller, a throttle control structure is also set on the handlebar. However, the throttle control structure in the present technology does not have a protective structure. Since the throttle control structure is located on the handlebar, it is easy to be accidentally triggered during operation, resulting in false triggering of the throttle control. Summary of the Invention

[0004] This invention provides a handrail control mechanism for a micro-tiller that prevents misoperation of the throttle control.

[0005] To solve the above-mentioned technical problems, the present invention provides a micro-tiller handle control mechanism, comprising:

[0006] The handlebars are connected to the main body of the mini-tiller;

[0007] The base is fixedly mounted on the handrail;

[0008] A trigger is rotatably mounted on the base via a pivot. The trigger is connected to the throttle control line. The trigger can rotate relative to the pivot in a first direction from a first position to a second position to drive the throttle control line to increase the throttle opening. The trigger can also rotate relative to the pivot in a second direction from a second position to a first position to drive the throttle control line to decrease the throttle opening.

[0009] An anti-collision mechanism is disposed on the base. The anti-collision mechanism is movable relative to the base to achieve a first state and a second state. In the first state, the anti-collision mechanism can lock and position the trigger so that the trigger is held in the first position. In the second state, the anti-collision mechanism can open the trigger so that the trigger can rotate relative to the pivot.

[0010] As a preferred embodiment of the above technical solution, a limiting plane is formed on the trigger, and the anti-collision mechanism includes a locking plate with a locking plane. The limiting plane and the locking plane are parallel to the axial direction of the rotating shaft. The locking plate can move relative to the base to reach a first set position and a second set position. When the locking plate is in the first set position, the locking plane can contact the limiting plane, thereby enabling the anti-collision mechanism to reach a first state. When the locking plate is in the second set position, the locking plane can separate from the limiting plane, thereby enabling the anti-collision mechanism to reach a second state.

[0011] As a preferred embodiment of the above technical solution, the micro-tiller handle control mechanism further includes a return spring, a pressing surface is formed on the side of the trigger near the locking plate, a locking part is provided on the locking plate, a locking plane is formed on the locking part, and the return spring elastically acts on the locking plate so that the locking plate has an elastic return force to move from a second set position to a first set position. When the trigger deviates from the first position in a first direction, the locking plate can make the front end of the locking part abut against the pressing surface under the action of the elastic return force.

[0012] As a preferred embodiment of the above technical solution, the locking plate is disposed on the side of the base, and the locking plate has an oblong hole. The rotating shaft cooperates with the oblong hole so that the locking plate can move along the length direction of the oblong hole.

[0013] As a preferred embodiment of the above technical solution, the base is a rectangular block structure, the oblong hole is parallel to the lower surface of the base, and the locking plane is parallel to the lower surface of the base.

[0014] As a preferred embodiment of the above technical solution, the front end of the locking plate is provided with a bent portion, and the bent portion is provided with a mounting hole. The bent portion is parallel to the front surface of the machine base. The micro-tiller handle control mechanism also includes a positioning rod. The front end of the positioning rod has a cap top. The positioning rod passes through the mounting hole and is connected to the machine base. The return spring is sleeved on the positioning rod and is located between the bent portion and the cap top. The positioning rod is parallel to the waist-shaped hole and extends away from the machine base.

[0015] As a preferred embodiment of the above technical solution, the locking plate is provided with a spherical handle.

[0016] As a preferred embodiment of the above technical solution, a control switch is also provided on the base, and the control switch is electrically connected to the control element on the micro-tiller body through a wire.

[0017] As a preferred embodiment of the above technical solution, the base is provided with a receiving opening, the front part of the trigger is disposed in the receiving opening, and the trigger is provided with a trigger spring.

[0018] As a preferred embodiment of the above technical solution, the locking part has a downwardly rolled arc-shaped part at one end near the trigger, and the arc-shaped upper surface of the arc-shaped part extends to the locking plane.

[0019] This invention provides a handlebar control mechanism for a mini-tiller, comprising a handlebar, a base, a trigger, and an anti-collision mechanism. The base is fixed to the handlebar, which is connected to the mini-tiller body. The handlebar controls the mini-tiller's direction of travel. The base is fixed to the handlebar, and the trigger is mounted on the base via a pivot. The trigger is connected to a throttle control cable. During operation, manually holding the trigger rotates it in a first direction from a first position to a second position. Simultaneously, pulling the throttle control cable increases the throttle, boosting power. Releasing the trigger rotates it in a second direction, returning it to the first position. During the process, the throttle is reduced by pushing the throttle control cable. The anti-collision mechanism is located on the base and can move on the base to achieve a first state and a second state. When no throttle operation is required, the anti-collision mechanism is in the first state, locking the trigger in the first position. At this time, the trigger cannot be turned whether it is manually held or clamped by other external forces. When throttle control operation is required, the anti-collision mechanism is moved to achieve the second state, at which time the trigger can be opened. When the trigger is manually held, it can be turned. Based on this, it can effectively prevent accidental operation of the throttle of the tiller.

[0020] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

Detailed Implementation

[0031] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention 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 invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] See Figures 1 to 9 As shown, an embodiment of the present invention provides a handle control mechanism for a micro-tiller, comprising:

[0033] Handlebar 10 is connected to the main body of the mini tiller;

[0034] The base 20 is fixedly mounted on the handrail 10;

[0035] The trigger 30 is rotatably mounted on the base 20 via the pivot 100. The trigger 30 is connected to the throttle control cable 40. The trigger 30 can rotate relative to the pivot 100 in a first direction from a first position to a second position to drive the throttle control cable 40 to increase the throttle opening. The trigger 30 can also rotate relative to the pivot 100 in a second direction from a second position to a first position to drive the throttle control cable 40 to decrease the throttle opening.

[0036] The anti-collision mechanism 80 is mounted on the base 20. The anti-collision mechanism 80 can move relative to the base 20 to achieve a first state and a second state. In the first state, the anti-collision mechanism 80 can lock the positioning trigger 30 so that the trigger 30 is held in the first position. In the second state, the anti-collision mechanism 80 can open the trigger 30 so that the trigger 30 can rotate relative to the rotating shaft 100.

[0037] This embodiment provides a handrail control mechanism for a mini-tiller, comprising a handrail 10, a base 20, a trigger 30, and an anti-collision mechanism 80. The base 20 is fixed to the handrail 10, which is connected to the mini-tiller body. The handrail 10 controls the mini-tiller's direction of travel. The trigger 30 is mounted on the base 20 via a pivot 100 and is connected to a throttle control cable 40. During operation, manually holding the trigger 30 rotates it in a first direction from the first position to the second position. Pulling the throttle control cable 40 increases the throttle and power. Releasing the trigger 30 rotates it in a second direction from the second position. During the process of returning to the first position, the throttle control line 40 is pushed to reduce the throttle. The anti-collision mechanism 80 is set on the base 20 and can move on the base 20 to achieve the first state and the second state. When the throttle operation is not required, the anti-collision mechanism 80 is in the first state, thereby locking the trigger 30 in the first position. At this time, the trigger 30 cannot be turned whether it is manually held or clamped by other external forces. When the throttle control operation is required, the anti-collision mechanism 80 is moved to achieve the second state. At this time, the trigger 30 can be opened. When the trigger 30 is manually held, it can be turned. Based on this, it can effectively prevent the accidental operation of the throttle of the tiller.

[0038] In specific application scenarios, in the existing technology, when the mini-tiller is in the operating state, the mini-tiller is in a stopped state when the lever is released, and the mini-tiller moves when the lever is held. When the grip on the lever is tightened, the throttle is increased. Without the anti-collision mechanism 80, the mini-tiller is in a stopped state. Especially when the operator is away, the lever may automatically open the throttle due to vibration or external impact, which may pose a significant safety hazard.

[0039] Furthermore, in this embodiment, the second direction is the opposite of the first direction. Specifically, in this embodiment, the first direction is counterclockwise, while the second direction is clockwise. The trigger 30 in this embodiment is provided with a trigger spring 90, which provides a clockwise restoring force for the trigger 30. The trigger spring 90 is a torsion spring structure. In addition, the trigger spring 90 in this embodiment is connected to the rotating shaft 100, and the trigger 30 is provided with a hanging opening 301. The trigger spring 90 is hung in the hanging opening 301, which can prevent the trigger spring 90 from detaching.

[0040] In addition, the rotating shaft 100 in this embodiment is a pin structure, which is fixed to the base 20 by a snap ring 150. The front of the trigger 30 is a block structure, and the rear of the trigger 30 is a handle.

[0041] In a further embodiment of this invention, a limiting plane 302 is formed on the trigger 30, and the anti-collision mechanism 80 includes a locking plate 801 with a locking plane 805 formed on it. The limiting plane 302 and the locking plane 805 are parallel to the axial direction of the rotating shaft 100. The locking plate 801 can move relative to the base 20 to reach a first set position and a second set position. When the locking plate 801 is in the first set position, the locking plane 805 can contact the limiting plane 302, thereby enabling the anti-collision mechanism 80 to reach a first state. When the locking plate 801 is in the second set position, the locking plane 805 can separate from the limiting plane 302, thereby enabling the anti-collision mechanism 80 to reach a second state.

[0042] In this embodiment, the locking state of the trigger 30 is achieved by the cooperation of the limiting plane 302 and the locking plane 805. Specifically, since the limiting plane 302 and the locking plane 805 are parallel to the axial direction of the rotating shaft 100, when the limiting plane 302 and the locking plane 805 are in contact, the trigger 30 cannot rotate in either the counterclockwise or clockwise direction. This not only ensures a stable locking state, but also simplifies the overall structure and makes locking more convenient.

[0043] In a further embodiment of this invention, the micro-tiller handle control mechanism further includes a return spring 110. A pressing surface 303 is formed on the side of the trigger 30 near the locking plate 801. A locking part 806 is provided on the locking plate 801. A locking plane 805 is formed on the locking part 806. The return spring 110 exerts an elastic force on the locking plate 801 so that the locking plate 801 has an elastic return force that moves from the second set position to the first set position. When the trigger 30 deviates from the first position in the first direction, the locking plate 801 can, under the action of the elastic return force, cause the front end of the locking part 806 to abut against the pressing surface 303.

[0044] When in operation, the locking plate 801 is moved towards the second set position, causing the limiting plane 302 and the locking plane 805 to disengage, thus releasing the locking state of the trigger 30. At this point, holding the trigger 30 allows operation of the throttle. With the trigger 30 held, it is deviated from the first position, and the front end of the locking part 806 abuts against the pressing surface 303. This prevents the locking plane 805 from resetting during operation, which would prevent the trigger 30 from reaching the first position. Under the action of the return spring 110, as the trigger 30 rotates between the first and second positions, the locking part 806 moves on the pressing surface 303 until the trigger 30... When the first position is reached, the locking part 806 disengages from the pressing surface 303 and automatically resets to the first set position. Moreover, when the locking part 806 abuts against the pressing surface 303, it can also provide a boosting effect, which can offset part of the reset force of the trigger spring 90, making the trigger grip easier. When the trigger 30 is released, it can act as a buffer, allowing the trigger 30 to automatically return to the locked position. In this embodiment, it is only necessary to push the locking plate 801 at the beginning to separate the limiting plane 302 and the locking plane 805 to operate the trigger 30, which can be easily completed with one hand, making the operation very simple and convenient.

[0045] In a further embodiment of this invention, a locking plate 801 is disposed on the side of the base 20, and a waist-shaped hole 802 is provided on the locking plate 801. The rotating shaft 100 cooperates with the waist-shaped hole 802 so that the locking plate 801 can move along the length direction of the waist-shaped hole 802.

[0046] In a further embodiment of this invention, the base 20 is a rectangular block structure, the oblong hole 802 is parallel to the lower surface of the base 20, and the locking plane 805 is parallel to the lower surface of the base 20.

[0047] In a further embodiment of this invention, the front end of the locking plate 801 is provided with a bent portion 803, and the bent portion 803 is provided with a mounting hole 804. The bent portion 803 is parallel to the front surface of the base 20. The micro-tiller handle control mechanism also includes a positioning rod 130. The front end of the positioning rod 130 has a cap top 120. The positioning rod 130 passes through the mounting hole 804 and is connected to the base 20. The return spring 110 is sleeved on the positioning rod 130 and is located between the bent portion 803 and the cap top 120. The positioning rod 130 is parallel to the waist-shaped hole 802 and extends away from the base 20.

[0048] In this embodiment, the waist-shaped hole 802 and the positioning rod 130 work together to enable the locking plate 801 to move along a set straight trajectory.

[0049] Furthermore, in this embodiment, the positioning rod 130 is provided with a threaded section 140, which is connected to the base 20. It can first adjust the adjustment of the reset force of the reset spring 110.

[0050] In a further embodiment of this invention, a ball handle 808 is provided on the locking plate 801.

[0051] In this embodiment, the base 20 is provided with a receiving opening 201, and the front part of the trigger 30 is disposed in the receiving opening 201.

[0052] Specifically, in this embodiment, the locking plate 801 is a straight plate structure in the shape of a triangle, and the base 20 is a rectangular block structure. The front end of the locking plate 801 is bent to form a bent part 803, and the lower end of the locking plate 801 is bent to form a locking part 806. The upper surface of the locking part 806 is a locking plane 805. The locking plate 801 is located on the side of the base 20 and is parallel to the side of the base 20. The snap ring 150 is located on the outside of the locking plate 801 and limits its movement. The oblong hole 802 and the positioning rod 130 are used together to... The mechanism is assembled into a movable track that moves along the length of the base 20. The locking part 806 is located below the base 20 and parallel to the lower surface of the base 20. The receiving opening 201 on the base 20 is a rectangular opening. The rectangular opening is formed on the rear surface of the base 20 and extends to the lower surface of the rectangular opening. When the trigger 30 is in the first position, the pressing surface 303 and the bottom surface of the rectangular opening cooperate with each other to limit the trigger 30. In addition, the pressing surface 303 and the limiting plane 302 are perpendicular to each other.

[0053] In addition, in this embodiment, the bent portion 803 cooperates with the front surface of the base 20 to limit the locking plate 801.

[0054] In a further embodiment of this invention, the locking part 806 has a downwardly rolled arc-shaped part 807 formed at one end near the trigger 30, and the arc-shaped upper surface of the arc-shaped part 807 extends to the locking plane 805.

[0055] In this embodiment, the arc-shaped portion 807 serves as a transition to prevent the trigger 30 from jamming during reset.

[0056] In a further embodiment of this invention, a control switch 60 is also provided on the base 20. The control switch 60 is electrically connected to the control element on the micro-tiller body through the wire 50. Pressing the control switch 60 can shut off the power to enable one-handed operation and improve the convenience of operation.

[0057] In this embodiment, a speed control mechanism 70 is provided on the base 20. The speed control mechanism 70 is used to position the trigger 30 at any set position between the first position and the second position.

[0058] The constant speed mechanism 70 in this embodiment includes a constant speed pin 701 and a constant speed spring 702. The top of the trigger 30 is provided with a downwardly recessed receiving opening 304, and the side of the trigger 30 is provided with a locking opening 305, which extends to the top of the trigger 30. The base 20 is provided with a mounting hole on the side of the trigger 30, corresponding to the locking opening 305. The constant speed pin 701 is disposed in the mounting hole. The constant speed spring 702 exerts an elastic force on the constant speed pin 701 so that the constant speed pin 701 has a restoring force away from the trigger 30. The top of the constant speed pin 701 is provided with a locking head 703.

[0059] In this embodiment, when the throttle control is performed, the trigger 30 rotates from the first position to the second position when it is held. When the speed control mechanism 70 is working, it presses the speed control pin 701, causing the speed control pin 701 to extend. When the trigger 30 is released, the trigger 30 returns to the first position from the second position under the action of the trigger spring 90. The locking head 703 extends into the locking head 703 to prevent the trigger 30 from continuing to return to the set position.

[0060] Furthermore, in this embodiment, multiple constant speed pins 701 can be set at different positions as needed to control the trigger 30 to stay at different positions so as to achieve different constant speed control, such as 30% and 70% throttle control.
