Description

[Detailed description of the invention] (Field of industrial application) This invention is a mobile agricultural machine such as a tiller, a management machine, and a power tiller. This relates to a step device that prevents the aircraft from moving forward.

(Prior Art) Conventionally, mobile agricultural machines such as trailers, management machines, and tillers have been equipped with running wheels and an engine mounted on a stand installed at the bottom of the machine, and the recoil starter is pulled forward to power the engine. There are known devices that start the engine.

(Problem that the present invention aims to solve) However, if the aircraft is only supported by a stand installed at the bottom of the aircraft, when the recoil starter is pulled forward, the aircraft with running wheels will move forward and the aircraft will collapse. There is a problem that the engine becomes unstable and the starting operation of the engine becomes difficult.

The present invention was devised in order to solve these problems in view of the above-mentioned actual situation, and although the stand is supported by the aircraft body equipped with running wheels, recoil does not occur when starting the engine. Even if the starter is pulled forward, the aircraft will not move forward and will be supported in a stable state, improving the operability of starting.Furthermore, a stand is provided that will not interfere with the aircraft's movement during work. The purpose of this invention is to provide a step device for a mobile agricultural machine.

(Means for Solving the Problems) In order to achieve the above object, the technical means taken by the present invention is to mount an engine with a recoil starter facing forward on the upper part of the aircraft body equipped with running wheels, and In a mobile agricultural machine, a stand supporting the machine is rotatably installed at the bottom of the machine below the starter. A step is provided at the rear of the base end of the stand and is supported by a frame bar protruding from the body, and a guide groove for the frame bar is formed in the step toward the base end, The present invention is characterized in that the step is housed on the underside of the machine body in conjunction with the rotated stand.

(Function of the invention) With the above configuration, when starting the engine mounted on the aircraft, by placing one foot on the step and pulling the forward recoil starter, the base end of the step is pivoted. A downward force acts on the stand bar protruding from the stand and the frame bar protruding from the fuselage that supports the tip side, locking the stand, supporting the fuselage in a stable state, and starting the engine easily. can be done. In order to move the aircraft, when the rotatable stand is rotated upward to the rear, the base end of the step pivoted on the stand moves upward, and the tip supported by the frame bar protruding from the aircraft body moves upward. The side moves while being guided by a guide groove provided toward the proximal end of the step, and the step is stored together with the stand on the underside of the machine body.

(Embodiment) The drawing shows an embodiment of a step device for a mobile agricultural machine equipped with a stand according to the present invention, in which 1 is a power tiller equipped with left and right running wheels 2, an engine frame 3 engine 4 above
A stand 5 for supporting the fuselage is pivoted to the lower part of the engine frame 3 so that it can rotate upward and be stored on the underside of the fuselage. Reference numeral 6 denotes a transmission case provided on the rear side of the engine frame 3, and a handle 8 extends rearward and upward from the tip of a handle frame 7 whose base end is attached to the transmission case 6. . A forward-facing recoil starter 9 is attached to one side of the engine 4, and the engine 4 can be started by pulling the recoil starter 9 from the front of the aircraft. The stand 5 is positioned below the recoil starter 9.

Reference numeral 10 denotes a step provided on the side of the machine body on which the recoil starter 9 is mounted, and the base end of the step 10 is located at a position protruding from the body of the stand bar 11 fixed to the middle part of the stand 5. It is supported on a shaft so that it can move up and down. Further, as shown in FIG. 3A, the distal end side of the step 10 is located behind the base end of the stand 5 and is connected to the engine frame 3.
supported on a frame bar 12 protruding from the
Next, the guide groove 13 of the frame bar 12 is formed toward the proximal end of the step 10 by inverting and bending the step 10 toward the back side. When storing the stand 5, as the stand 5 is rotated rearward and upward as shown in FIG. It moves, turns upside down, and is stored on the underside of the fuselage together with the stand 5. Reference numeral 14 denotes a spring for switching the stand 5 between the retracted position and the downwardly projecting position of the aircraft body; 1;
5 is a stopper that supports the stand 5 in a protruding position, 16 is a flat washer, and 17 is a cotter pin.

FIG. 4 shows another embodiment, in which a guide stopper 13a into which the frame bar 12 is fitted is formed on the distal end side of the guide groove 13, substantially perpendicular to the guide groove 13, and the stand 5 is positioned below the fuselage. When the frame bar 12 is protruded, the frame bar 12 fits into the guide stopper 13a and the stand 5 can be reliably locked.

In the above configuration, when starting the engine 4, the driver located at the front of the aircraft must
When you put your foot on the step 10 and pull the recoil starter 9, the stand bar 11 protruding from the middle of the stand 5, which pivots the base end of the step 10,
A downward force acts on the frame bar 12 protruding from the fuselage frame 3 supporting the front end side, and the stand 5 located below the recoil starter 9 is locked in a locking manner, thereby stabilizing the aircraft without moving forward. Since the engine is supported in this state, the engine can be started easily. When carrying out work with the stand 5 stored, the step 10 provided on the side of the machine rotates upward at the rear of the stand 5, and the base end rotates about the stand bar 11 and moves upward. The distal end side moves along the frame bar 12 while being guided by the guide groove 13 toward the proximal end of the step 10, and is automatically stored inside out on the underside of the machine body, so there is no hindrance to running. It will never be. Furthermore, in the other embodiments, the stand 5 can be locked in a position protruding downward from the machine body, so that the machine body can be supported in a more stable state.

(Effect of the invention) In short, the present invention mounts an engine with a forward-facing recoil starter on the upper part of the fuselage equipped with running wheels, and rotates a stand that supports the fuselage at the bottom of the fuselage below the recoil starter. In a mobile agricultural machine, the base end is pivoted on the side of the machine body to a stand bar protruding from the middle part of the stand, and the tip side is located behind the base end of the stand and protrudes from the machine body. A step is provided to be supported by a frame bar, and a guide groove for the frame bar is formed in the step toward the proximal end, and the step is connected to a stand that is rotated upward at the rear to allow the step to be supported on the underside of the fuselage. Because the aircraft is equipped with running wheels and is supported by a stand installed at the bottom of the aircraft, when starting the engine, if you put your foot on the step and pull the recoil starter forward, Since the stand is locked and the aircraft body is supported in a stable state without moving forward, the engine can be started easily and the starting workability can be improved. Moreover, if you rotate the stand upward and store it on the underside of the aircraft, the steps will automatically be stored on the underside of the aircraft in conjunction with the rotation of the stand, so the steps will not interfere with the aircraft's movement. This has very useful practical effects, such as being able to perform work smoothly.
