Description

[Detailed Description of the Invention] The present invention relates to agricultural machinery, particularly floating hand tractors.

Such floating hand tractors are described in Utility Model Application Publication No. 11645 of 1932 and Utility Model Application Publication No. 13793 of 1947.

The former is equipped with a propulsion device in the form of a paddle wheel on the front float, and a motor-driven tilling device in the rear.

Similarly, the latter has a paddle wheel on the front float (ship-shaped sliding body), a paddle board at the rear that functions as a float, whose vertical position can be adjusted freely, and what looks like a tilling device (R
) is provided.

Both differ from the manual device of the present invention in that the rear tilling device is powered.

The object of the present invention is to provide a floating hand tractor whose harrow, which can be moved up and down, can be easily manually operated.

To achieve the above object, the present invention includes a U-shaped operating handle connected to the upper part of the housing and inclined upwardly toward the rear, supported by an upright rod, and a lower side of the U-shaped handle. It is an object of the present invention to provide a hand tractor characterized in that a handle for vertically moving the harrow for turning the harrow is attached to a horizontal pipe which is pivotally connected to an upright support rod and supports a harrow span pipe.

The harrow actuating handle is in its lowest position and contacts the harrow in its highest position, and when the handle is pivoted upward, the span tube is
If it is configured to pivot downward, it will be easier to operate.

In the following, other features of the invention will be explained in more detail with reference to the drawings, which illustrate embodiments.

The floating hand tractor 10 includes a vacuum floating housing 11, a harrow 12 with an adjustable handle 13, a pair of paddle wheels 14, 14a, and a mudguard plate 1 for an engine drive 16.
5, has a gear box 17 and a tractor operating handle 18.

As shown in FIG. 3, the paddle wheels 14, 148, floating housing 11, and harrow 13 are provided in this order from the front in the direction of travel, and these have the same width.

The vacuum type floating housing 11 is made by welding two bowl-shaped bodies preferably made of thin galvanized iron plates with a sleeve around the periphery, and allows the housing to float on water by extracting air from the hollow part.

The housing 11 has an engine drive section 16 in the upper center part.
A base frame is provided for removably attaching it.

A quarter-circular mudguard plate 15 is connected to its front end to prevent muddy water splashing in contact with the paddle wheels 14, 14a from splashing onto the engine drive unit 16.

A front base frame extension 20 is provided above the mudguard plate 15 and a gear box 17 is attached thereto, and a tractor operating handle 18 is connected to the center of the floating housing 11.

The working hand 18 is inclined upwardly and is supported by a pair of vertical tubes 21, 22 and reinforced at the U-shaped end 24 by a U-shaped galvanized iron tube 23.

A removable harrow 12 is connected to the back surface of the vacuum floating housing 11 via an operating frame 25.

This operating frame 25 includes a pair of spanning pipe bodies 26, 27,
It consists of a tube 28 and an adjustable hollow operating handle 13.

These span pipes 26. 27 is connected to tube 28 via a pivot connection of vertical tubes 21,22.

The position shown in FIG. 1 is the lowest position of the handle 13, and the harrows 12 are in the uppermost position and are in contact with each other.

When the handle 13 is pivoted upwards, the span tube 26.2
7 is preferably configured to pivot downward.

This is possible if the tubes 26, 27 and 28 are pivoted on an axis parallel to the vertical tube 21 and provided with a fan-shaped meshing portion or the like.

The pipe body 28 is used to adjust the insertion depth of the harrow against soil damage.
A freely adjustable harrow actuation handle 13 is connected to the center of the harrow so that the operator can easily operate it with one hand.

An engine drive unit 16 mounted on an engine base frame 19 at the top of the vacuum floating housing drives a transmission gear 29 via a V-shaped belt 30, a driven pulley 31 and a transmission shaft 32.

The tension of the V-shaped belt 30 is controlled by an idler pulley 33 provided on the engine base frame 19 by the engine drive section 16 and gear box 17.

The transmission gear 29 further drives another shaft 34 to which a pair of paddle wheels 14, 143 are fixedly connected.
