Description

[Detailed explanation of the invention] This invention is a work machine attached to a power agricultural machine or a self-propelled work machine that works while traveling close to a ridge. The purpose of the present invention is to provide a marker wheel that serves as a steering target for moving forward along the vehicle.

For example, as shown in FIG. 1, a ridge forming machine as a working machine 1 is attached to a power agricultural machine 2 such as a tractor, and an auger 4 extending from the side of the power agricultural machine 2 to the 3' side of the ridge is used to form a ridge at the 3' side of the ridge. This is because the ridge forming work is performed correctly when the soil is scooped up into the auger case 5 and the mixed soil released onto the side surface 3a and top surface 3b of the ridge 3 is applied to the ridge 3 using the ridge coating plate 6 to form the ridge. In this case, it is desirable that the rear wheel 7 on the ridge 3 side of the power agricultural machine 2 is separated from the hem of the side surface 3a of the ridge 3 by about 20 cm, but in this case, the front wheel 8 is further away from the ridge than the rear wheel T. Because it was far away from the ridge 3, it was difficult to determine the distance between it and the ridge 3, and it was extremely difficult to steer the power agricultural machine 2 to advance parallel to the ridge 3.

Therefore, this invention aims to provide a marker wheel that is the target of this steering operation, and its configuration will be explained based on one embodiment shown in the drawings. A circular marker wheel 9 having approximately the same diameter as the front wheel 8 of the front wheel 8 has a center shaft 9a protruding from the front wheel 8 on the ridge 3 side.
A sheath tube 10 is attached to the rim 8a so as to protrude outward from the rim 8a, and the center shaft 9a is inserted into and out of the sheath tube 10 at will, and the center shaft is fixed at the tip of an adjustment bolt 11 screwed into the sheath tube 10. A marker wheel 9 is formed on the side of the front wheel 8 so as to be adjustable in and out of the left and right by making it possible to press the marker wheel 9a against the sheath tube 10.

Reference numeral 13 in the figure is a gauge wheel for determining the running height.

Since the marker wheel according to this invention is constructed as described above, when performing the ridge coating and shaping work, the marker wheel 9 is placed in a position where the ridge 3 is correctly coated and formed on the ridge coating plate 6. The front wheel 8 is also adjusted in and out so that it comes into contact with the hem of the side surface 3a of the ridge 3, and while moving the power agricultural machine 2 forward, the power agricultural machine 2 is moved so that the marker wheel 9 comes into contact with the hem of the side surface 3a.
By operating the handle 12, the ridge forming machine always maintains the optimum position, so accurate ridge forming is performed, and there is no fear that the rear wheel T etc. will collapse the ridge 3. Also, the marker wheel 9 Since the front wheel 8 rotates together with the front wheel 8, even if there are irregularities at the bottom of the ridge 3, the running resistance is small and straightness is maintained, and weeds do not get tangled.

Furthermore, the marker wheel of this embodiment can also be applied to ridge forming work, and this marker wheel is similarly useful when installing or using other work equipment instead of the ridge forming machine. When using a traveling type work machine, a marker wheel can be similarly applied to its front wheel.
