Description

Technical Field

[0001] The utility model relates to the technical field of riding type micro-farming equipment, in particular to a steering wheel of four-wheel riding type micro-farming equipment. Background Art

[0002] The steering wheel of the existing four-wheeled riding micro-tillage equipment includes a ring-shaped round tube, multiple support rods, and a connecting seat. One end of the multiple support rods is connected to the connecting seat, and the other end is connected to the round tube. The connecting seat is connected to the steering shaft. Since the control buttons and the rod-shaped throttle switch are arranged directly below the steering wheel of the four-wheeled riding micro-tillage equipment, and the axes of the multiple support rods on the existing steering wheel are located in the same horizontal plane, in order to reserve operating space for the throttle switch and the control buttons, the entire steering wheel needs to be moved upward along the axial direction of the steering shaft, which may easily cause the steering wheel to be too high, making it inconvenient for the driver to operate the steering wheel. There is an urgent need for a steering wheel for the four-wheeled riding micro-tillage equipment that can reserve operating space for the throttle switch and the control buttons and has an appropriate height. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of the utility model is to provide a steering wheel for a four-wheel ride-on micro-tillage equipment, which can reserve operating space for the throttle switch and control buttons without affecting the driver's operating comfort and has a moderate height.

[0004] The technical solution adopted by the present invention is as follows: a steering wheel of a four-wheeled riding micro-tillage equipment, including a ring-shaped circular tube, and also including a plurality of circumferentially spaced inclined and inwardly bent support rods, one end of each of the support rods is connected to the circular tube, and the other end is connected to the steering shaft on the four-wheeled riding micro-tillage equipment, and the plurality of support rods are bent inwardly and cooperate with the circular tube to reserve operating space for components on the four-wheeled riding micro-tillage equipment.

[0005] Explanation: The components on the four-wheel riding micro-tillage equipment may be a control button and a lever-shaped throttle switch.

[0006] Principle of the technical solution:

[0007] One end of the support rod is connected to the steering shaft, and the other end is connected to the round tube. Since the support rod is bent inward, the support rod first ensures that the steering wheel is in the normal position. Secondly, the support rod is bent inward, and the distance between the support rod and the orthographic projection of the round tube increases. When the driver controls the throttle switch to rotate circumferentially in the vertical plane, the driver's hand will not touch the support rod, and the throttle switch can be smoothly controlled, and the driver can press the control button without obstacles.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] The multiple support rods of the present invention are all bent inward, so that the distance between the support rods and the orthographic projection of the circular tube is increased, thereby reserving sufficient operating space for the throttle switch and the control button. Moreover, the existing multiple support rods are all tilted. If it is desired to reserve operating space for the throttle switch and the control button, the steering wheel needs to be moved upward along the steering shaft axis, or the diameter of the circular tube needs to be increased, both of which will affect the driver's operating comfort.

[0010] As a preferred embodiment of the present invention, the support rod includes a horizontal straight portion and an inwardly bent portion, one end of the bent portion is connected to the round tube, and the other end is connected to the horizontal straight portion, and one end of the horizontal straight portion is connected to the steering shaft on the four-wheel riding micro-tillage equipment.

[0011] Beneficial effect: The support rod can be stably connected to the steering shaft through the horizontal part, and the bent part can increase the distance between the bent part and the orthographic projection of the circular tube, thereby reserving sufficient operating space for the throttle switch and control button.

[0012] As a preferred embodiment of the present invention, one end of the support rod connected to the round tube is provided with a control portion for grasping, and the hand grasps and drives the control portion to rotate circumferentially, and the control portion drives the round tube to rotate circumferentially.

[0013] Beneficial effects: The design of the control part can add an extra control point on the steering wheel. When the direction needs to be adjusted quickly, the driver can directly control the steering wheel rotation by gripping the control part, thereby improving operational flexibility. In certain emergency situations, the driver can quickly adjust the direction with one hand.

[0014] As a preferred embodiment of the present invention, the control part is a sphere, the sphere is located above the circular tube, and the sphere is connected to the support rod.

[0015] Beneficial effect: The sphere is located above the round tube, making it easy for the driver to hold it.

[0016] As a preferred embodiment of the present invention, a plurality of concave surfaces are circumferentially spaced apart on the lower surface of the circular tube, and the concave surfaces smoothly transition to the lower surface of the circular tube.

[0017] Beneficial effect: The concave design increases the friction between the driver's hand and the round tube, which can prevent slipping and enable the driver to stably control the rotation of the round tube.

[0018] As a preferred embodiment of the present invention, it further includes a connecting seat, which is fixedly connected to multiple support rods, and the connecting seat is connected to the steering shaft on the four-wheel riding micro-tillage equipment.

[0019] Beneficial effect: the support rod can be stably connected to the steering shaft through the connecting seat.

[0020] As a preferred embodiment of the present invention, a receiving cavity for receiving a nut connected to one end of a steering shaft on a four-wheeled riding micro-tillage device is provided in the connecting seat, the inner surface of the bottom of the receiving cavity abuts against the nut, the connecting seat is connected to one end of a steering shaft on the four-wheeled riding micro-tillage device, and the connecting seat is clamped with a connecting cover for shielding the receiving cavity.

[0021] Beneficial effects: The nut is located in the accommodating cavity and is connected to the steering shaft, and abuts against the accommodating cavity. The design of the connection between the connecting seat and the steering shaft ensures a stable connection between the connecting seat and the steering shaft. The connecting cover is snap-fitted to the connecting seat, which can easily cover and expose the accommodating cavity. BRIEF DESCRIPTION OF THE DRAWINGS
