Description

[Detailed description of the invention] Conventionally, a reaper with auxiliary wheels installed on both left and right sides in front of the cutting blade has already been proposed, but this reaper is used for reaping crops that are planted at the top of ridges, such as soybeans, adzuki beans, or wheat. case,
The auxiliary wheels of the known reaper were supported by horizontal support shafts protruding from the bottom of the vertical support rods, so when the auxiliary wheels were run along the slopes on both sides of the ridge,
It was biased to one side and tended to roll, making it difficult to move straight.

The present invention improves the above-mentioned drawbacks, and also provides an auxiliary wheel for a reaper that can be adjusted with a small amount of adjustment depending on the height of the ridge and width of the ridge, and can be easily adjusted over a wide range. This is a reaper that is equipped with grass dividers on both sides of the front and a cutting blade attached to the rear of the reaper, with a pair of left and right holding cylinders on the machine frame on both sides in front of the cutting blade, as seen from the front. It has an inverted V shape and is installed so that the lower part is rearward when viewed from the side, and a support rod is fitted into these holding cylinders so that it can be adjusted and fixed up and down, and a support shaft is attached to the lower part of the support rod so that the outer side is lower. It is characterized in that the auxiliary wheels are supported on these support shafts in an inverted V-shape when viewed from the front.

The embodiment shown in the drawings will be explained below.1
is a cutting blade attached to the front part of a machine body 3 having wheels 2, 2, and grass dividing bodies 5, 5 are attached to the front parts of the frames 4, 4 on both sides, and the grass dividing body 5 on the left side is attached to the front part of the frame body 3 on both sides. The pulling frame 6 provided at the rear is equipped with a chain having a large number of lugs, and the frame body 4 on the right side is constructed with a binding device 7 interposed in the middle. In addition to this, a lifting guide frame 8 is provided.

In addition, at the rear of the machine body 3, the cutting blade 1, wheels 2,
Engine 9 that drives the 2 chain, binding device 7, etc.
is mounted, and a handle 10 is fixed to the front part thereof.

The stays 11, 11 attached to the front parts of the left and right frames 4, 4 are tilted inward so that the gap between the lower parts becomes narrower when viewed from the front, and the lower part is rearward than the upper part. Holding cylinder 12,1
2 is fixed to the lower ends of the support rods 13, 13, which are inserted into the holding cylinders 12, 12 so as to be vertically slidable.
The support shafts 14, 14 are welded perpendicularly to the support rods 13, 13, and the support shafts 14, 14 are attached to the auxiliary wheels 15, 15.
It is pivoted on.

Therefore, as shown in FIG. 5, the support rods 13, 13 are inclined so that the spacing at the bottom becomes narrower when viewed from the front, and the peripheral surfaces of the auxiliary wheels 15, 15 are arranged on the slope of the ridge 16, as shown in FIG. The auxiliary wheels 15 face each other at a small angle (the angle of inclination of the auxiliary wheels 15 is approximately 10 degrees). 15, 15 follow the slope of the ridge 16 well and roll,
Drive by following the curve of ridge 16.

In addition, if the width of the ridge 16 is different or the height thereof is different, the left and right support rods 13, 13 are adjusted up and down by the same amount, and the pin 17 is connected to the hole in the holding cylinders 12, 12 and the support rod 13. By inserting and fixing the auxiliary wheels 15, 15 into any of the holes 13a of the ridges 13 and fixing them, as shown in FIG. The height of the cutting blade relative to the top of the ridge 16 is kept approximately constant, and the cutting blade can be cut at a predetermined cutting height.

Furthermore, during the reaping process, a large amount of weeds grow in the furrows, but since the lower part of the support rod protrudes outward and is tilted backwards, the weeds are pushed down by the support rod, causing the grain to grow in the grain culm. It is possible to prevent it from being pruned.

Although the wheels 2 of the reaping machine in this embodiment are shown as being on the left and right sides, it may be a single-wheel type reaping machine that runs on the top of the ridge.

As mentioned above, the present invention is a reaper that is equipped with grass dividers on both sides of the front and a cutting blade attached to the rear.
A pair of left and right holding cylinders are attached to the machine frame on both sides in front of the cutting blade so that they form an inverted V shape when viewed from the front, and the lower part is at the rear when viewed from the side, and the support rods are moved up and down on these holding cylinders. The ridge width is adjustable and fixed, and support shafts are protruded from the lower part of the support rod so that the outer side is lower, and each of the auxiliary wheels is supported on these support shafts in an inverted V shape when viewed from the front. If the area is narrow and high, lowering the auxiliary wheels will narrow the wheel width, ensuring that the auxiliary wheels do not ride up on adjacent ridges and that their outer periphery touches the slope of the ridge to be harvested at a small angle. The aircraft can travel straight without meandering.

In addition, in normal fields with wide or flat ridges, when the auxiliary wheels are raised and installed, the distance between the left and right auxiliary wheels becomes wider, allowing stable mowing while minimizing left-right tilting of the machine. It is possible to reduce the cutting height.

Furthermore, there are many weeds growing in the fields.
Since the support rod of the auxiliary wheel is tilted rearward, the weeds can be suppressed and less likely to be cut together with the grain culms.
