Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mowing machine used for mowing ridges and the like.

[0002]

2. Description of the Related Art Conventionally, as a mowing machine for mowing ridges and the like, there is a mowing machine comprising a clipper-type or disk-type cutting blade and a narrow traveling wheel disposed behind the cutting blade. . As such a mower, for example, Japanese Unexamined Patent Publication No. Sho 60-2
JP-A-59117 and JP-A-61-141815 disclose a mowing machine comprising a cutting blade having a predetermined cutting width and a plurality of narrow running wheels disposed behind the cutting blade. Have been.

[0003]

In the above-mentioned conventional mowing machine, the running wheels arranged behind the cutting blade are formed to be narrow. For this reason, even if a plurality of these running wheels are arranged on the left and right, on a narrow ridge or a work place with a lot of unevenness, the posture of the aircraft may be distorted due to derailing from the ridge or dropping of the wheel into the concave part, etc. easy.

Therefore, stable mowing work is difficult to perform,
The work efficiency was low.

[0005]

The present invention employs the following technical means in order to solve the above-mentioned problems. That is, a mowing machine comprising the cutting blade 3 according to claim 1 and the wide running wheels 2 disposed on the rear side of the cutting blade 3, and a mowing machine according to claim 2. A cutting blade 3 having a predetermined cutting width, a wide traveling wheel 2 disposed behind the cutting blade 3, and an engine 5 disposed behind the traveling wheel 2. This is a configuration of a mowing machine to be used.

[0006] In the mowing operation, the grass on the ridge is cut by a cutting blade 3 disposed in front of the traveling wheel 2 while running on the ridge, for example. At this time, according to the configuration of the first aspect, since the traveling wheel 2 is wide, it is difficult for the traveling wheel 2 to come off even in a narrow ridge,
In addition, even in a work place having many irregularities, the traveling wheel 2 is less likely to fall into the concave parts. As a result, the attitude of the aircraft is less likely to collapse.

According to the second aspect of the present invention, the cutting blades 3 are arranged on the front side of the wide traveling wheels 2 and the engine 5 is arranged on the rear side thereof. Since 2 is wide, it is difficult for the traveling wheel 2 to fall out of the recess even in a work land having many irregularities, even if the ridge is narrow in width. At the same time, the front-rear weight balance of the aircraft with the traveling wheel 2 as the ground contact portion is suitable. Thereby, the attitude of the airframe is further stabilized.

[0008]

As described above, the present invention is characterized in that the cutting blade 3 and the wide running wheel 2 arranged behind the cutting blade 3 are provided. The mowing machine is configured to perform relatively stable work traveling, thereby increasing the efficiency of mowing work. A cutting blade 3 having a predetermined cutting width, a wide traveling wheel 2 disposed behind the cutting blade 3, and an engine 5 disposed behind the traveling wheel 2 according to claim 2. The mowing machine is characterized in that the mowing operation is performed more stably, and the mowing work efficiency is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. A body (body) 1 has a traveling wheel 2 mounted on a lower portion thereof, and a handle 4 provided on a rear portion thereof through an engine 5 and a handle support rod 7 projecting rearward long. (Cutting blade) 3 is provided.

The handle support rod 7 is configured to be able to be driven to rotate about the longitudinal axis 6. The vertical axis 6 which is the center of rotation of the handle 4 is set at a position eccentric to one side from the center of the cutting width of the cutting device 3. Reference numeral 8 denotes a mission case, in which gear transmission mechanisms 11 and 12 for transmitting power to a traveling transmission shaft 9 to the traveling wheels 2 and a cutting transmission shaft 10 to the reaper 3 are installed. ing. In front of the transmission case 8, a first transmission case 13 containing the cutting transmission shaft 10 and four cutting transmission gears 14, 15,.
A second transmission case 18 in the up and down direction, which meshes the internal shafts 16 and 17 with an interior shaft, and a third transmission case 20 in which the drive shaft 19 is installed in the front and rear direction with an interior shaft, are connected to each other. Especially,
The second transmission case 18 is provided in a vertically inclined state when viewed from the front so that the mowing transmission shaft 10 is located higher inward than the drive shaft 19. On the lateral side of the third transmission case 20, a driven shaft 21 parallel to the drive shaft 19 is provided so as to be supported by a support frame 22 projecting from the third transmission case 20 side. A drive wheel 23 and a driven wheel 24 are mounted on the drive shaft 19 and the driven shaft 21, and a band saw type endless cutting blade 25 is wound around the drive shaft 19 and the driven shaft 21 to constitute the cutting device 3.

The traveling wheel 2 comprises an engine 5, a transmission case 8, a first transmission case 13, and a second transmission case 18.
And the like, and arranged to be driven downward from the traveling transmission shaft 9 through the worm wheel mechanisms 26 and 27, the traveling drive shaft 28, and the transmission chain 30 in the chain case 39. It is linked. A pair of bevel gears 33 and 34 meshing with a bevel gear 32 provided on a shaft 31 orthogonal to the mowing transmission shaft 10 are provided on the shaft so that a clutch 35 is inserted into one bevel gear 33 side. Bevel gear 3
2, vertical axis 6 via worm wheel transmission mechanisms 36, 37
