Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a traveling device in a single-wheel type reaper for harvesting culms.

(B) Prior art Conventionally, in a two-wheeled reaper, it has been known to provide one auxiliary wheel that can be raised and lowered at the front of the machine body, as disclosed in Japanese Patent Application Laid-Open No. 52-10211.
5, and a wheel-type reaper is also already known.

(c) Problems that the invention aims to solve In general, two-wheeled crops are used in fields where ridges are formed by cultivating soil to weed out crops such as soybeans during the growing process, or by cultivating soil to prevent lodging due to strong winds. When reaping is carried out with a reaper, auxiliary wheels are provided at the front of the machine body as in the known two-wheeled reaper, and the auxiliary wheels roll on the furrows or roll between the furrows. However, the left and right wheels enter the furrows and roll, causing the cutting blade to point upwards, which can significantly reduce cutting performance or, in extreme cases, cause the cutting blade to turn downward.

In this regard, the wheels of a wheel-type reaper run on the ridges where crops are planted, so they do not have the above-mentioned drawbacks, but the machine becomes extremely unstable downward, making it extremely difficult to maneuver. It was not possible to carry out harvesting work in the field.

(d) Means for solving the problem The present invention is to provide a single running wheel at the center of the width of the machine near the contact part, so that the running wheel runs on the ridge when harvesting crops on the ridge. None, two auxiliary wheels on the left and right are installed on the back of the grass division at both ends of the front so as to be spaced apart from each other on the left and right sides of the running wheels when viewed from the front, and the auxiliary wheels correspond to the furrows on both sides of the ridge. In addition, by setting these auxiliary wheels to approximately the same height as the traveling wheels, it is possible to cut the cutting blade at approximately the appropriate angle in a flat field, and from that state, the auxiliary wheels can be set at approximately the same height as the traveling wheels. When installed by lowering it by an amount corresponding to the height of the furrow, the cutting blade will be at the appropriate cutting angle as when reaping in a flat field, and the front part of the machine will be moved by the auxiliary wheels that roll between the furrows on both sides. The above-mentioned problem was solved by supporting and preventing left and right tilting.

(E) Function When performing reaping work in a flat field, setting the auxiliary wheels at approximately the same height as the single running wheel in the center near the rear will ensure stable running despite the -axle type. The cutting operation can be easily carried out while the cutting operation is being carried out, and the cutting angle of the cutting blade can be maintained at an appropriate state.

In addition, when reaping in a field with ridges, the auxiliary wheels are set lower than the running wheels by an amount corresponding to the height of the ridges, the running wheels are run on the ridges, and the auxiliary wheels are moved between the ridges on both sides. By rolling the mower, the mowing angle of the mower blade is maintained appropriately, and the left and right sides of the mowing device are supported by auxiliary wheels, respectively, so that stable mowing can be performed without tilting to the left or right.

(F) Embodiment To explain an embodiment of the present invention with reference to the drawings, reference numeral 1 denotes a running wheel mounted on a shaft at the center of the rear of the machine body, and a cutting blade 2 is mounted on the front part of the machine body, and its - Combing body 3 installed at the front side
A reaping device A consisting of a combing body 4 and the like provided on the other side is provided, and at the lower part of the combing bodies 3, 4, there is a weeding body 5, 5, and following them, the combing bodies 3, 4. Auxiliary weeding bodies 6, 6 are provided which protrude outward from the lower part of the blade.

Further, a narrow guide 8 extending from the weeding body 5 to the rear thereof is provided on the negative side of the combed body 3, and a binding device 7 is provided behind the combed body 4 on the other side.

Auxiliary wheels 10.10 are arranged on the backs of the left and right weeding bodies 5, 5, and are spaced apart from both sides of the running wheels 1 when viewed from the front. As shown in FIG. 6, vertical bearings 9 and 9 are provided to support the auxiliary wheels 10 and 10, respectively, and a plurality of locking holes 1 are provided.
A holding rod 11.11 made of a tube having a diameter of
．． Since the auxiliary wheels 10.1 and 13 are fixed by split pins, depending on whether the field is flat or ridged.
The auxiliary wheel 10 on the side of the combing body 4 has its front surface covered with a weeding body 5 and an auxiliary weeding body 6, and between the weeding body 5 and the tying device 7. It is in.

Further, the front surface of the auxiliary wheel 10 on the side of the combing body 3 is covered with a weeding body 5 and an auxiliary weeding body 6 following it, and the outer surface is covered with a narrow guide 8.

Therefore, when harvesting and tying is done in a flat field, the second
As shown in Figures 1 and 4, by making the auxiliary wheels 10.10 approximately the same height as the traveling wheels 1, the cutting blade can be set at an appropriate cutting angle, while the left and right auxiliary wheels 10.10 prevent the reaping device from tilting from side to side. In addition, when harvesting and tying crops such as soybeans on the ridges, the auxiliary wheels 10 and 10 are set lower than the running wheels 1 as shown in Fig. 5, and the running wheels 1 run on the ridges. When the auxiliary wheel 10.10 runs in the groove between the furrows, the cutting angle of the cutting blade can be maintained at an appropriate state similar to the flat field described above, and the single running wheel 1 can Even though the aircraft is traveling on a ridge, it does not tilt left or right because both front sides of the aircraft are supported by auxiliary wheels 10° and 10, respectively.

(g) Effect of the invention Since the invention is constructed as described above, the auxiliary wheels 10.1
If the auxiliary wheels 10 and 10 are set at approximately the same height as the running wheel 1, stable reaping work can be performed in a flat field even though it is a single-wheel type, and the auxiliary wheels 10 and 10 can be set at approximately the same height as the running wheel 1, which is located approximately in the middle of the machine. If set lower, the left and right auxiliary wheels 1 can be lowered even though the single running wheel 1 is running on the ridges in a ridged field, which is an extremely unstable working condition.
By running the 0.10 in the grooves between the furrows on both sides, the cutting angle of the cutting blade 2 is maintained appropriately, and the left and right sides of the front of the machine are supported by the auxiliary wheels 10.10, so that it does not tilt left or right. Good reaping work can be performed in extremely stable conditions.
