Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a lawn for preliminarily cutting grass that has been cut into a predetermined length and width by a dedicated machine or the like, and collecting and collecting pre-cut grass that has been cut so that it can be peeled from the ground. It concerns harvesters.

[0002]

2. Description of the Related Art When turf is to be transferred to another place or sold, the lawn turf is first peeled off, and a plurality of cut turf cut and cut into a predetermined size are piled up and tied together. State is required. Therefore, first, cut the grass vertically and horizontally with a special machine such as a cutter and cut the root so that it can be separated from the ground. Then, the harvesting work is performed in which the pretreated cut grass is picked up and collected. In the past, the harvesting work was covered manually.

[0003]

However, since it is labor intensive to pick up and rotate the cut grass on the ground with a middle waist, it is desired to mechanize the cut grass harvesting work. An object of the present invention is to realize and provide a lawn harvester that can pick up and collect cut grass that has been pretreated and is on the ground.

[0004]

In order to achieve the above object, the present invention provides a cut grass on the ground, which is a state in which a lawn is cut into predetermined vertical and horizontal dimensions and is root-cut so as to be peelable from the ground. A walking type lawn harvester is constructed by equipping a walking type self-propelled aircraft with a pickup part that is picked up and lifted on the aircraft.
It is characterized in that a movable binding machine capable of stacking a predetermined number of cut grasses collected by the pickup section and binding them is connected to the rear portion of the self-propelled machine body.

[0005]

[Function] As the self-propelled aircraft progresses, the pick-up section picks up the cut grass on the ground and lifts it up on the self-propelled aircraft, so that it becomes mechanized to pick up the cut grass on the ground with the middle waist and rotate it. . Then, in the binding machine that is connected to the aircraft and towed, you can stack multiple cut grass collected on the aircraft and tie it, so you can manually collect the collected grass from the self-propelled aircraft to the binding machine in the rear. Although it is a semi-automatic type of moving, it is possible to finish the grass lawn while running the lawn harvester without moving the collected cut grass to another place for binding. Become. For good turf growth, we would like to avoid running heavy machinery on the lawn as much as possible, but since the turf harvester of the present application is configured to be a walking type, it is possible to use as much as possible per unit grounding area on the traveling device. There is an advantage that the load can be lightened and the harvesting work can be done without damaging the grass. In addition, as described above, since the binding machine is connected in the form of being pulled, it is possible to increase the weight of the self-propelled aircraft like a riding type and to increase the load per unit ground area of the mobile binding machine itself. It is possible to prevent the size of the grass from becoming large, and it is possible to perform the work steps up to the grass bundle with less damage to the grass. Further, by disconnecting the binding machine and performing the cut grass collection work only by the self-propelled machine body, it can be used as a grass harvester with a smaller turn.

[0006]

[Effects of the Invention] Therefore, it is possible to mechanically perform the cutting work of cut grass, avoid damage to the lawn due to a heavy load, and bind the cut grass collected on the machine while the harvest work is running. We were able to provide a walk-behind lawn harvester that can make a bundle of grass. Further, there is also an advantage that the binding machine is disconnected when it is not bound during work traveling, and the operation and handling by only the walk type harvester becomes more convenient.
