JP 2009-107477 A

In the axle type gas engine management machine of Patent Document 1 described above, the exhaust gas is clean compared to a general gasoline fuel management machine, but the continuous operation time per gas supply cylinder is short ( Therefore, if the gas supply cylinder runs out of gas during the cultivation operation, the gas supply cylinder must be replaced separately, and the gas supply cylinder is installed during the cultivation work on the field. I had to go to the house, car, barn etc.
Therefore, in the case of an axle type gas engine management machine that has run out of fuel, the resistance rod at the rear of the management machine must be removed and moved to the house, car, or barn where the fuel gas cylinder is stored. He was forced to do a very cumbersome and inefficient task of having to move the wheel with the wheel attached to the front of the control machine.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a means for moving an axle type gas engine management machine during non-working such as a lack of gas.

  The present invention has been made in order to solve these problems in view of the above circumstances, and includes a gas engine that operates with gas as a fuel in a fuselage, and a gas supply cylinder that supplies gas to the gas engine. Engine type management comprising: an axle that is rotated by power output from the gas engine, a plurality of tilling claws provided on the axle, and a handle frame that extends rearward and upward from the rear of the fuselage A machine is characterized in that at least three or more wheels are distributed and arranged along the front face toward the front of the machine body.

  According to the first aspect of the present invention, the airframe is equipped with a gas engine that operates using gas as fuel, and a gas supply cylinder that supplies gas to the gas engine, and is driven to rotate by power output from the gas engine. A gas engine type management machine comprising an axle, a plurality of tilling claws provided on the axle, and a handle frame extending rearwardly and upwardly from the rear part of the machine body. Since the above wheels are distributed and attached along the front surface, the wheels attached to the front of the machine body can be changed to 90 degrees forward even if the gas runs out during the tilling work on the field. Can easily move by pushing and pulling with the handle in contact with the ground, and can easily go to the gas supply cylinder to the house, car, barn, etc. Ukoto can. Even if the posture is changed about 90 degrees forward, the handle frame can be operated at the same position because the handle frame extends obliquely backward (about 45 degrees).

It is a side view of the gas engine type management machine which concerns on embodiment of this invention. It is a perspective view of a gas engine type management machine concerning an embodiment of the invention in this application. It is a side view which shows the state which can move the gas engine type management machine which concerns on embodiment of this invention in an upright state.

  Hereinafter, an axle type gas engine management machine according to an embodiment of the present invention will be described with reference to the drawings.

  First, the overall configuration of an axle type gas engine management machine will be described. As shown in FIGS. 1 and 2, the axle-type gas engine management machine 1 is disposed so as to be inclined in the vertical direction, and has a rotating shaft 3 a that supports a rotating body 3 such as a tilling claw 3 b so as to be rotationally driven. A mission case 5 that pivots to the left and right, a bifurcated handle frame 6 that is fixed to the mission case 5 and extends upward toward the rear side (right side in the figure), and a machine that is fixed to the mission case 5 A gas engine 9 mounted on the base frame 7, and the operator holds the grips 6 a and 6 b at the tip of the handle frame 6 to operate the airframe 2 from the transmission case 5 and the gas engine 9. It is configured.

  In addition, a wheel capable of traveling on the road and the like is attached to the front portion of the airframe 2 in a state where an axle type gas engine management machine, which will be described later in the gist of the present invention, is changed by about 90 degrees to the front. Yes. That is, the moving wheel S has four wheels S mounted freely on the fender F that covers the front part of the gas engine 9 and the top of the tilling claw 3b. When the vehicle is moved on the road without starting the engine, the moving wheel S comes into contact with the ground by tilting the axle type gas engine management device about 90 degrees forward, and then the axle is held with the handle frame 6. It is configured so that it can be moved back and forth by pushing and pulling a gas engine management machine of the type.

The mounting structure of the moving wheel S will be described in more detail. As shown in FIGS. 1 and 2, two of the four moving wheels S (A, B) are approximately the total length of the body in side view. Moving wheels A and B are provided at both ends of an axle 31 extending in the left-right direction at a position higher than the middle height, from a substantially central position in the left-right direction of the airframe to the front end of the bracket 30 extending obliquely forward and upward from the mission housing M. It is attached freely.
In addition, since the outer diameter of the axle 31 is smaller than the center inner diameter of the moving wheels A and B, it absorbs the impact when the management machine is tilted forward and tilted, thereby adding to the management machine itself. Impact can be reduced.
Of the other moving wheels S, the other two (C, D) are viewed from above the fender F near the approximate center in the left-right direction of the aircraft at a position lower than the substantially middle height of the aircraft in a side view. Moving wheels C and D are attached to both ends of an axle 33 extending in the left-right direction at the front end of a bracket 32 that extends obliquely forward and upward.
Similarly to the moving wheels A and B, the moving wheels C and D are configured to reduce the impact applied to the managing machine itself by absorbing the shock when the managing machine is tilted forward and tilted. Yes.
As described above, it can be easily moved by pushing and pulling the handle of the axle type gas engine management machine with the convenience of four moving wheels.
In the embodiment, the four moving wheels have been described. However, the structure in which the body is stabilized by only the wheels, that is, the three wheels may be dispersedly arranged along the front surface of the body toward the front. is there.

As shown in FIG. 1, the handle 6 includes gripping portions 6a and 6b at both left and right ends.
A main clutch lever 11 for operating a main clutch, which will be described later, is disposed in front of the grip portion 6b on the left side of the machine body. When the operator grips the grip portion 6a together, the main clutch is engaged. It is configured to be an operation. Further, a throttle lever 10 is disposed in front of the right grip 6b so that the operator can operate the rotation of the gas engine 9 via the throttle wire 10a by operating the throttle lever 10. It is configured.

  On the other hand, the gas engine 9 (see FIG. 1) includes a belt transmission mechanism (not shown) in the belt cover 13, and the rotational transmission force of the engine output shaft is input to the transmission case 5 by the belt transmission mechanism. Transmitted to the shaft. The belt transmission mechanism is provided with a belt tension clutch (not shown) for turning on and off the transmission of the rotational driving force of the gas engine 9, and is disposed on the gripping portions 6a and 6b at the tips of the handle frame 6 described above. Transmission of the rotational driving force of the gas engine 9 can be turned on and off by operating the clutch lever 11.

  In the moving wheel of the axle type gas engine management machine configured as described above, the axle type management machine is relatively light in weight, and the fuel is gas instead of gasoline. Thus, even if the posture is changed by about 90 degrees and tilted, the work can be performed without causing any problems in the normal startability thereafter.

  In addition, the moving wheel S itself can also serve as a shock absorbing bumper for an axle type gas engine management machine in normal tillage work, which can dramatically improve workability. done.
