Description

Detailed Description of the Invention The present invention relates to a mobile agricultural machine that performs ground work such as plowing or weeding by disposing ground work wheels at the front or rear of the propulsion wheels, and improves work performance and maneuverability all at once. This is what I tried to achieve.

The present invention provides a rotary body for ground work that is provided with a driven wheel that contacts the propulsion wheel and rotates in the opposite direction on the front or rear part of the propulsion wheel attached to the axle, and that rotates integrally with the driven wheel on the side of the driven wheel. are arranged so as to appear to overlap the propulsion wheels in a side view.

That is, by driving the ground work wheels in a rotation direction opposite to the rotational direction of the propulsion wheels, it is now possible to reliably and powerfully perform ground work at a work speed equal to the travel speed plus the rotation speed of the ground work wheels.

In addition, the drive structure is simplified by driving the ground working wheels in reverse rotation by using a driven wheel that contacts the propulsion wheels and rotates in the opposite direction. As a result, the front and rear length of the entire aircraft is short, making it possible to move around smoothly.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

In the figure, a pair of left and right propulsion wheels 4, 4 are attached to an axle 3 mounted on the lower part of a traveling mission case 2 that receives power from an engine 1, and the side surfaces of ridges A, A are applied to the rear of the fuselage. Culti wheel 5 as a rotating body for ground work,
5 and a tiller 6 are sequentially connected and equipped.

The soil cultivator 6 is supported by a hitch 7 attached to the rear part of the mission case 2 via a frame 8 connected to the frame 8 so as to be rotatable and fixed around the vertical axis.

Also, from this frame 8 downwardly, a chart wheel 5,
Support arms 9, 9 of No. 5 are vertically installed so as to be swingable back and forth, and these support arms 9, 9 are supported by springs 12,'
12 toward the propulsion wheels 4, 4.

The cultivation wheels 5, 5 are fixed to a support shaft 10 whose both ends are loosely fitted to the lower ends of the support arms 9, 9.

Further, on the inner side of the culti wheels 5, 5, a protrusion 1 is provided on the outer periphery of the propulsion wheels 4, 4 to serve as a propulsion rub.
3. 13. A small-diameter driven wheel 11, N, which is engaged with and driven in reverse rotation, is fixed to the support shaft 10.

As the driven wheels 11, 11 are driven to rotate in the reverse direction, the chart wheels 4, 4 are integrally driven to rotate.

Further, the culti wheels 4, 4 are formed to have a larger diameter than the driven wheels 11, 11, and when the driven wheels 11.11 are engaged with the propulsion wheels 4, 4, when viewed from the side, It overlaps with the propulsion wheels 4, 4.

According to the above configuration, as the machine moves forward using the propulsion wheels 4, 4, the culturing wheels 5, 5 act on the sides of the ridges A, A to weed and relatively till the topsoil, and then the cultivator 6 The sides of ridges A and A will be finished and shaped.

Since the culti wheels 5, 5 are driven to rotate in the opposite direction at a higher speed than the propulsion wheels 4 in the traveling direction, the ridges A, A are cut at a high speed equal to the traveling speed plus the rotational speed change in the reverse direction. This allows for powerful and reliable ground work.

In addition, the propulsion wheels 4, 4 and the cultiform wheels 5, 5 are arranged so as to overlap when viewed from the side, and as a result, the longitudinal length of the aircraft body is shortened, making it easier to handle the aircraft and making it easier to maneuver around. It can be done smoothly.

Incidentally, the ground working wheels are not limited to the chart wheels 5, 5, but may be other wheels such as a rotary body exclusively for tillage.
