Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a control device for an auxiliary wheel for a power cart,

The present invention relates to a sub-wheel control device for a power-powered wheelbarrow capable of controlling a left-right rotation of a sub-wheel provided so as to be able to be steadily dragged while facilitating a direction change in a hand-

A power cart having motive force and being able to drag with a hand or a power of a hand wheel, which is mainly applied to a short distance transportation, has a main driving wheel and a subordinate wheel including a mission below a frame provided with a loader on the top, A handle bar and a power unit for driving the main drive wheels by the power transmitting means are provided.

The auxiliary wheel provided at the rear of the frame can be easily turned in the direction of movement of the handle bar by using the self-rotation of the auxiliary wheel such as a caster so as to facilitate the change of direction during the movement process.

However, in a house, orchard, or field where power carts are used, the moving length is the same. In this process, one person holds the handle bar and adjusts the hand bar to move immediately, The auxiliary wheel can not be moved in a straight line according to the state of the ground, and it is irregular moving state. Therefore, when the object is lowered or raised, the work is performed while the movement is stopped. There were many.

The object of the present invention is to provide a subwoofer control device for a power wheelbarrow that allows the power cart to be moved immediately by the operation of the lever so that it can be loaded or unloaded on the load during the moving process, .

The present invention has been proposed in order to realize the above object,

A power cart having a main wheel which is provided with a handlebar and a power unit in a frame provided with a loading box and driven by a power unit at the bottom, and a sub wheel which is pivoted to rotate,

And a spline shaft provided on a shaft of the auxiliary wheel, the spline shaft being slidably engaged with the spline shaft, the spline shaft being connected to the detachable attachment, So that the rotation of the auxiliary wheel can be controlled by the attachment / detachment of the attachment / detachment part to / from the spline shaft part by the operation of the handle lever.

71: sliding groove 72: spline groove

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view of a power cart to which the present invention is applied,

The power cart is provided with a main wheel 4 provided with a loading box 2 on the upper part of the frame 1 and driven by the power unit 3 in the downward direction and auxiliary wheels 5 pivoted to rotate,

A handle bar 6 and a power unit 3 such as an engine for imparting power to the main drive wheel 4 by a power transmitting means are provided at the rear of the frame 1.

2 and 3 show the installation structure of the auxiliary wheel of the present invention,

A detachable fitting 7 fitted to the center shaft 51 of the auxiliary wheel 5 and having a detachment means by a lifting and lowering operation,

A connecting lever 9 connected to the attaching / detaching port 7 so as to be installed on the frame 1 so as to flow into the supporting space 10,

The end of the connecting lever 9 is connected to the handle lever 61 by the cable 11,

.

The detachment means includes a spline groove 72 formed in the sliding groove 71 of the detachment opening 7 and an upper portion of the spline groove 72. The detachment opening 7 is fitted into a center shaft 51 having a spline portion 52 formed thereon, The spline does not engage with the spline, and when the spline is lowered, the coupling of the spline causes the center shaft 51 to be caught by the slit 7 and not rotate.

3, the handlebar 6 (see FIG. 3) is provided with a handlebar 61, which is provided on the handle bar 6 as shown in FIG. 3, when the handlebar 6 is operated, If the connecting lever 9 is pulled by the cable 11 by the handle lever 61, the connecting lever 9 is detached and attached around the supporting lever 10 The spline groove 72 formed in the sliding groove 71 of the attaching / detaching port 7 is disengaged from the spline portion 52 of the center shaft 51 and the center shaft 51 The auxiliary wheel 5 is rotated while being arbitrarily rotated and freely redirected according to the adjustment of the handlebar 6.

When the hand wheel is to be immediately advanced during use to work in an orchard, a house or the like, if the handle lever 61 is loosened while the auxiliary wheel 5 is immediately positioned, the cable 11, The disengagement port 7 is lowered and the spline groove 72 formed in the desorption port 7 is coupled to the spline portion 52 of the center shaft 51 so that the center shaft 51 can not be rotated The auxiliary wheel 5 is not pivoted at a predetermined position, so that the power hand wheel is moved only in a straight forward direction at a predetermined position. By adjusting the traveling speed of the wheel, the wheel can be moved forward and backward without adjusting the handlebar. Work can be done additionally.

As described above, the present invention enables the power cart to be operated by a single operation of a straight line or by arbitrary traveling direction, so that it can be efficiently used in an orchard or a house in a rural area, thereby improving work efficiency and saving labor costs And the like can be obtained.
