DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the bogie for a mower according to the present invention will be described in detail with reference to the drawings.

1 and 2, reference numeral 10 is a bogie for a mower according to the present invention. This trolley 10 for mowers is provided with a mower 12, and the mower 12 is moved in the direction of the tip with the cutting blade 14 while swinging the mower reciprocally substantially parallel to the ground. It is a bogie for a mower that cuts grass. In this mowing machine 10, an operator holds the handle 16 with his / her left hand and swings the lever 18 to the left / right while holding it with his / her right hand, whereby the mowing machine 12 fixed to a mounting table 20 integrated with the lever 18 is provided. Is configured to swing right and left. In addition, the wheels 22 are interlocked with the swing of the mower 12.
Is provided with a moving means 24 for rotating the mower 12 by a certain amount and moving the mower 12 forward in the direction of the tip thereof. Furthermore, in order to prevent the mower 12 from moving backward,
A moving direction limiting means 26 is provided.

The moving means 24 includes an arm 28 that swings integrally with the lever 18, a conversion jig 30 that converts the swinging motion of the arm 28 into a rotary motion, and a belt wheel that is rotated by the conversion jig 30. 32 and a belt 34 for transmitting the rotational movement of the belt wheel 32 to the wheels 22. As shown in FIG. 3, the conversion jig 30 is rotated by the rotating member 36 that rotates in conjunction with the arm 28, the claw member 38 rotatably attached to the rotating member 36, and the claw member 38. And a rotary shaft 42 to which the ratchet wheel 40 and the belt wheel 32 are fixed. That is, the claw member 38 pushes and rotates the claw wheel 40 in conjunction with the swing of the arm 28, so that the rotary shaft 42 can be rotated by a certain amount in one direction. A releasing means 43 for pushing up the pawl member 38 to release the engagement with the pawl wheel 40 is provided, and the knob 45 of the releasing means 43 is rotated to push up the pawl member 38. There is.

Further, as shown in FIG. 4, the movement direction limiting means 26 includes a ratchet wheel 46 fixed to the wheel shaft 44 and a claw member for rotating the ratchet wheel 46 only in one direction and stopping the rotation in the opposite direction. And 48. That is, the wheel shaft 44 of the wheel 22 is configured to rotate only in one direction so that the bogie 10 for the mower does not move backward.

The mower bogie 10 having such a structure is used by first mounting the mower 12 on the mounting table 20 and rotating and driving the cutting blade 14. With the mower 12 mounted, the operator holds the handle 16 in his left hand and the lever 18 in his right hand, and swings the lever 18 left and right. By swinging the lever 18 left and right, the grass mower 12 fixed to the mounting table 20 swings substantially parallel to the ground, and the grass on the ground is sequentially mowed by the cutting blade 14.

Here, the carriage 10 for the mower is moved by reciprocally swinging the lever 18 left and right.
First, when the lever 18 is swung to the left, the arm 28 integrated with the lever 18 is swung forward. As the arm 28 is swung, as shown in FIG. 3, the rotating member 36 engaged with the engaging member 50 at the tip of the arm 28 is rotated around the rotating shaft 42. The pawl member 38 pushes the pawl wheel 40 around by rotating the rotary member 36 around the rotary shaft 42. When the ratchet wheel 40 is pushed and rotated, the rotary shaft 42 to which the ratchet wheel 40 is fixed is rotated. By rotating the rotary shaft 42, the belt wheel 32 fixed to the rotary shaft 42 is rotated. When the belt wheel 32 is rotated, the rotational movement is transmitted to the belt wheel 52 shown in FIG. 1B by the belt 34, and the belt wheel 52 is rotated. When the belt wheel 52 is rotated, the wheel 22 having the wheel shaft 44 that is the same rotation axis as the belt wheel 52 is rotated. By rotating the wheels 22, the carriage 10 for the mower is moved forward, and the mower 12 is moved in the direction of its tip.

On the other hand, when the handle 18 is swung to the right, the arm 28 is swung rearward, and the turning member 3 is swung.
6 is rotated in the opposite direction. Even if the rotating member 36 is rotated in the opposite direction, the pawl member 38 does not engage with the ratchet wheel 40, and therefore the ratchet wheel 40 does not rotate. Since the ratchet wheel 40 does not rotate, the mower bogie 10 does not move while stopped. That is, when the handle 18 is swung to the right, the mowing machine 12 is swung to mow the grass while the carriage 10 for the mowing machine is stopped. Since the grass mower 12 is swung while the mower bogie 10 is stopped, the grass on the ground is evenly cut.

Therefore, the bogie 10 for mowers of the present invention performs mowing while moving a certain amount forward only when the handle 18 is swung to the left. When the mower 12 is swung by a certain angle or more, the pin head 51 of the rotating member 36 interferes with the engaging member 50. Therefore, the swing angle of the mower 12 is limited to a constant value.

Next, if the cutting blade 14 hits a stone or the like or goes up a slope, a force for moving the bobbin cutter 10 to the rear is exerted. The wheel shaft 4 of the wheel 22 is acted upon by the force that moves the mower bogie 10 rearward.
A force acts so that 4 rotates in the opposite direction. However, since the claw member 48 stops the reverse rotation of the ratchet wheel 46 fixed to the wheel shaft 44 by the movement direction restricting means 26 shown in FIG. 4, the wheel shaft 44 does not rotate in the reverse direction. Since the wheel shafts 44 do not rotate in the opposite direction, the bobbin mower 10 is prevented from moving backward.

The bogie 1 for the mower without mowing
When moving 0, the knob 45 of the releasing means 43 is rotated to push up the pawl member 38 to release the engagement of the pawl member 38 with the pawl wheel 40. Since the engagement of the claw member 38 with the claw wheel 40 is released, the carriage 10 for the mowing machine can be pushed and moved without swinging the mowing machine 12.

According to such a mower bogie 10, the mower 12 is mounted and fixed on the mounting table 20, and the lever 18 is swung left and right, whereby the mower 12 is substantially parallel to the ground. It is possible to mow the grass growing on the ground by moving the grass mower 12 forward by a fixed amount while swinging back and forth.

Furthermore, the vibration of the mower 12 is not directly transmitted to the worker, and there is no fear of damaging the worker's body. Further, since the mower 12 can be moved by using the swing motion, the mower 12 can be easily moved.
Can be moved. Further, by moving the mowing machine 12 by a fixed amount, it is possible to mow the grass on the ground evenly.

When the mower 12 is swung by a certain angle or more, the pin head 51 of the rotating member 36 interferes with the engaging member 50, so that the swivel angle of the mower 12 can be limited to a certain value. it can. For this reason, it is possible to prevent the cutting blade 14 from hitting an operator or the like due to the grass mower 12 swinging too much, and safety can be improved.

Further, the moving direction limiting means 26 can prevent the bobbin mower 10 from moving backward. Therefore, even if the cutting blade 14 hits a stone or the like or goes up a slope, the trolley 10 for the mowing machine is not moved backward, and the mowing machine 12 is prevented from moving in the direction of the operator. Then, the safety can be improved.

Further, when the lever 18 is swung to the left, the mower bogie 10 can be moved forward, and when swung to the right, it can be stopped. Therefore, the lever 18
When the is swung to the right, the mower bogie 10 is stopped, and the grass can be swung evenly while the grass mower 12 is swung.
