Description

[Detailed Description of the Invention] The present invention relates to a bumper that also serves as a stand for a management work machine, etc. That is, in the device of the present invention, when the bumper of the management work machine is formed into a half-folded shape and used as a bumper-like body, the above-mentioned half-folded shape can act as a divider without damaging crops, etc., and When a large impact is applied to the bumper, the center-folded shape absorbs the impact, and when used as a stand for a working machine, the center-folded shape becomes substantially straight and can be fixed in a predetermined manner when touching the ground.

Hereinafter, the present invention will be explained based on the drawings of embodiments of the device. In FIG. 1, A is a working machine, and this working machine A has an engine 2 mounted on the upper end of a transmission case 1, a support body 3 connected to the rear side of the transmission case 1, and a support body 3 connected to the rear side of the transmission case 1. A handle 4 is protruded upward from the rear of the transmission case 3, and a stabilizing rod 5 is protruded downward from the bottom of the transmission case 1.A working shaft 6 is protruded from both sides of the lower end of the transmission case 1 at the front. Disks 7, 7 are mounted on both sides of the work shaft 6, claws 8 are provided on the outer peripheries of the disks 7, 7, and a front plate 9 is provided protruding from the front side of the transmission case 1. , one end of a support rod 10 is rotatably supported on the front plate 9 by a pivot 11.
A tension spring 12 is installed so that the support rod 10 can be fixed and stabilized in the forward and downward directions of the work machine A.
and stoppers 13, 13, respectively. The tip of the support rod 10 branches left and right as shown in FIGS. 2 and 3, and the branch 1
Equipped with pins 15, 15 at the tips of 4, 14, the pins 15, 15 are slidably and rotatably inserted into the elongated holes 17, 17 on the intermediate backs of the rods 16, 16 from the left and right, and the rods 16 and 16 are connected. The inner end of the rod 16 is pivotally connected to the rod 18, and is pulled together by a tension spring 19, and the outer end is curved inward, and the rod 1
6 and 16 are the grounding body B in the state shown in FIG. 2, that is, the state in which the support rod 10 in FIG. 1 is stable downward, and the state in FIG. 10 can be distinguished from a stable bumper-like body C that protrudes forward. In addition, 20 in the figure
21 indicates a fender, and 21... indicates an obstacle such as a crop.

Regarding the bumper-shaped body C of the rods 16, 16 and the support rod 10, in FIG.
Obstacles such as crops 21 approaching 6 are the rod 1.
Guided to 6, 16, crop 21 with rod 16 and rod 16
... is separated, acts as a divider, and crops 2
1..., etc., become an obstacle and collide with the rod 16 or the rod 16, the rods 16, 16 will not be able to maintain their pivot point 1.
Since it has a center-folded shape at 8 parts, it moves in and out from that part and absorbs the impact.Also, even if the center-folded part moves back and forth, the elastic attraction of the tension spring 19 keeps the rod 16 and the rod 16
is restored to its original state.

Next, in FIG. 1, when the support rod 10 is rotated in the direction of the arrow B, the tensioning direction of the tension spring 12 moves from the pivot point 11 of the support rod 10 to beyond the fulcrum, and the tension spring 12 moves between the support rod 10 and the stopper 13. and are in contact,
The support rod 10 is stabilized downward, and in this state,
When the work implement A is placed in a grounded state, the pivot points 18 between the rods 16 and the rods 16 move back and forth from the folded shape due to the weight of the work implement A, and as shown in FIG. The pins 15, 15 at the tips of the branches 14, 14 inserted into the elongated holes 17, 17 move inward, and the rods 16 form a substantially straight line and are stably grounded, so that the work machine A is stabilized. Together with the rod 10, the claws 8 of the discs 7, 7 are floated and rotatable, forming a stable grounding body B, and when the engine 2 is started,
The disks 7, 7 can be rotated safely during inspection. Of course, in order to turn the rods 16, 16 and the support rod 10 into a bumper-like object C from this stable grounding object B, lift the handle 4 of the work implement A in FIG. When pulled, the support rod 10 rotates in the opposite direction of the arrow B due to the movement of the working machine A, and the support rod 10 and the stopper 13 come into contact with each other, automatically forming a bumper-like body C.

As explained above, in the device of the present invention, the rods 16, 16 are pivotally mounted 18 from the left and right in the front direction of the working machine A, and the bumper-like body C is formed by protruding in a tapered shape at the pivot position 18. However, the rods 16, 16 are working machine A.
When the rods 16 are positioned below the bumper, the rods 16 and 16 form a substantially straight line to form the grounding body B. Therefore, when used as the bumper C, the rods 16 and the rods The pivot point 18 of the rod 16 is bent in the middle, and the rods 16 and 16 act as a divider to separate the approaching crops, etc., and the rods 16
And when an obstacle collides with the rod 16, the rod 16,1
The folded shape of 6 retracts and absorbs the impact force, and
When the rods 16, 16 are turned downward into the grounding body B, the folded shape retracts and forms a substantially straight line, providing a stable stand for the working machine A.
