The swing bracket is swingably connected along the movement direction, the free end of the swing bracket is connected to the body via a swing connection rod, and the handle is variably held at the upper position and the lower position, respectively. A detachable locking device is interposed between the handle and the swing bracket, and a connection point between the swing bracket and the swing connection rod is held when the handle is held at a position above the handle. It is characterized in that the bracket is arranged at a position deviated from a straight line connecting a connection point of the handle of the bracket and a connection point of the swing connection rod to the body.

Operation Accordingly, the operator can actuate the locking device as needed to move the handle to the desired upper or lower position and hold the handle at the desired upper or lower position.

Embodiment Next, the present invention will be described based on an embodiment of the drawings.

In this embodiment, the present invention is applied to a deep-bed fertilizer, and this aircraft is provided with a single running wheel 2 and a sliding body disposed behind the wheel 2 as shown in FIG. And the sliding body 3 slides on the field scene to stably maintain the aircraft body 1 at the same time as the body 1 travels and moves on the field scene by the rotation of the wheels 2. I have. The wheels 2 are rotationally driven from above by a power device mounted on the body 1, that is, an internal combustion engine 4 via a gear reduction transmission device 5, so that the machine can travel.
Further, the body 1 is provided with a topdressing device 6 in a lower rear portion thereof. The topdressing device 6 is of a normal type in which fertilizer and chemicals are supplied from a supply source (not shown) through a hose or the like, and is rotatably attached to a lower end portion of the attachment beam 32 of the body 1. It has a boss portion 7, a plurality (four in this example) of topdressing tubes 8 radially extending from the boss portion 7, and an auxiliary support rod 9 radially extending between the topdressing tubes 8. When the operator rotates the wheels 2 while gripping the handle 10 at the rear of the machine body 1 during the operation, the topdressing device 6 rotates accordingly and inserts the topdressing pipes 8 sequentially into the ground. Fertilizers and chemicals are sent out from underground from the tip of the top fertilizer pipe 8.

The handle 10 has a loop shape, and is attached at its base 11 so as to be able to swing up and down by a pivot 12 attached to the body 1, and from there to an operator gripping portion 13 at the rear end. Extends rearward above.
Further, the handle 10 is provided with a lateral beam 14 (see FIG. 2) at an intermediate portion near the base 11 thereof.
A sleeve 16 provided at the upper end of a plate-shaped swing bracket 15 is rotatably supported. The swing bracket
The lower end 15 which is the free end of the swing is pivotally connected to the upper end of the swing connection rod 18 by a lateral pin 17,
The lower end of the swing connection rod 18 is swingably connected to the rear end 20 of the body 1 by another lateral pin 19. Further, the swing bracket 15 has a working position lateral hole 21 formed at a portion between the axis of the sleeve 16 and the axis of the lateral pin 17 as viewed in FIG. A moving position lateral hole 22 formed at a portion behind and obliquely above the lateral hole 21;
And 22 are spaced apart from each other in an arc direction on an arc line having a predetermined radius from the axis of the sleeve 16. In order to facilitate the vertical swing of the handle 10, as shown in FIG.
The working position horizontal hole 21 and the horizontal pin 17 are arranged so as not to be fixed in a state of being aligned. The transverse beam 14 has a fixed bracket member 23 for attaching a locking device L extending downwardly close to one side surface of the swing bracket 15, and the bracket member 23 is attached to the swing bracket 15.
A cylinder 24 of the locking device L is provided which extends in the lateral direction at a position aligned with the arc line on which the 15 lateral holes 21 and 22 are arranged. The cylinder 24 has a plunger 25 slidably provided therein, and when the tip of the plunger 25 is aligned with one of the lateral holes 21 or 22 of the swing bracket 15, the plunger 25 is in the hole 21 or 22. , Thereby preventing the pivoting bracket 15 from rotating with respect to the transverse beam 14. The plunger 25 is disposed in the cylinder 24 and has an inner end 26 of the cylinder 24 and a large diameter portion of the plunger 25.
The pressure is biased outward in the axial direction, that is, toward the swing bracket 15 by a compression coil spring 28 acting between the swing bracket 15 and the compression coil spring 28. The plunger 25 is an inner end 26 of the cylinder 24.
One end of the inner cable 29 of the Bowden cable is connected to the side,
The inner cable 29 extends outward from the inner end 26 of the cylinder 24,
Further, it extends rearward along the handle 10, and the other end is connected to an operation lever 30 pivotally attached to an operator gripping portion 13 at the rear end of the handle 10. The operating lever 30 is pulled down by an operator, thereby pulling the inner cable 29 to disengage the plunger 25 from one of the lateral holes 21 or 22 of the swing bracket 15, and moving the swing bracket 15 in the lateral direction of the handle 10. Rotate around the beam 14 and move the handle 10 to its base
It can be swung up and down around 11 pivots 12.

The swinging bracket 15 is engaged with the plunger 25 in its working position lateral hole 21 during normal work, so that the handle 10 is fixed at a relatively high upper position, that is, the position A shown by a solid line in FIG. The operator can appropriately operate the machine by gripping the operator gripping portion 13 at the rear end of the handle 10. However, when it is desired to move the machine by moving the topdressing mechanism 6 upward from the ground, such as when the machine is not working or the machine is turning, the operator pulls the operating lever 30 to pull the plunger. 25 is disengaged from the working position lateral hole 21 of the swing bracket 15, and the handle 10 is pivoted to a lower position, that is, a position B shown by a two-dot chain line in FIG. At this time, the swing bracket 15 is rotated forward around the axis of the horizontal beam 14 of the handle 10 to the position shown in FIG. 3, and the movement position lateral hole 22 of the swing bracket 15 is aligned with the plunger 25. I do. At this time, when the operator releases the operation lever 30, the plunger 25 engages into the movement position lateral hole 22 of the rotation lever 15, and fixes the handle 10 in the lower position. For this reason,
Since the operator gripping portion 13 of the handle 10 comes to a relatively low position, the operator can lift the handle 10 to easily maintain the topdressing device 6 considerably above the ground, and
The machine can be moved safely with minimal risk of contact with the ground or obstacles.

Reference numerals 30 and 31 in the figure denote stoppers provided on the swing bracket 15 for restricting the swing range of the handle 13. Further, horizontal holes 21 and 22 provided on the swing bracket 15 are added to work. Fine adjustment according to the physique of the person may be possible.

Effect of the Invention As is clear from the above description, the present invention allows the swing bracket and the swing connection rod to be freely foldable at the connection point between the swing bracket and the swing connection rod. A very large swing angle of the handle can be obtained, and the handle can be easily moved to a sufficiently low position when the traveling work machine is not working or turning, and the handle must be lifted at a minimum. At the very least, the machine can be easily moved and turned, and the working equipment can be held at a sufficiently high position to prevent the risk of damage by contact with the ground or obstacles. And the like.
