{Weeder for coupling excavator}

More particularly, the present invention relates to a mowing machine for connecting an excavator, and more particularly, to a mowing machine for connecting an excavator to an excavator, To an excavator connecting mower

In general, mowers are used as feed for compost and livestock to harvest natural weeds in orchards, seedlings, other rice paddies, gardens, roads and rivers.

An example of such a conventional lawn mower can be found in Korean Registered Patent No. 10-0578421 entitled " Chongqing Lawn Mower equipped with a loading box 50 ".

FIG. 1 and FIG. 2 are views showing a conventional heavy mowers having a loading box.

1 and 2, there are shown a main body 1 which is pulled by a tractor, a power shaft 2 which is supported on the main body 1 and is driven by receiving power from a power take-off shaft of the tractor, A weighing machine comprising a cutter portion (3) driven by receiving power from a power shaft (2), characterized in that the weigher is located behind the cutter portion (3) And a screw conveying member (4) which is contained in the receiving groove (4) and receives power from the power shaft (2) to transfer the weeds temporarily stored therein to one side A striking member 6 axially coupled to one end of the screw conveying member 5 for striking the transferred weeds backward and a striking member 6 disposed on the inner side of the striking member 6, 6a extending from the casing 7, A blowing fan 8 for receiving the power from the power shaft 2 and discharging the weeds stuck by the striking member 6 to the outside through the discharge pipe 6a, And a loading box 9 mounted on the main body 1 for storing weeds discharged from the pipe 6a. In the conventional lawn mower constructed as described above, the power of the tractor is transmitted to the power shaft 2 to rotate the pulley and the belt. By this power, the cutter unit 3 is rotated to cut the weeds, The wefts scattered by the screw conveying member 5 of the receiving groove portion 4 located at the back of the weft receiving portion 4 are temporarily accommodated.

The weeds temporarily housed in the receiving groove 4 are loaded on the loading box 9 by the blowing force of the blowing fan 8 and positioned rearward of the loading bay 50 in a cargo bay such as a cultivator, If you take the front about the axis, you can easily transfer to the tiller without any extra work.

However, in conventional lawn mowers, there is a risk of a safety accident due to the structure for rotating the loading box 9 in order to discharge the weeds loaded in the loading box 9. In particular, due to the structure in which the loading box 9 is rotated, There is a risk that the loading box 9 may be overturned when the vehicle runs.
