Description

Detailed Description of the Invention This invention provides a reaping device and a reaped culm transport bag f at the front of the machine.
In addition to providing a reaping transport section with This invention relates to a walk-behind type reaper configured to reap and transport planted grain culms laterally using a reaping and transporting section at the front of the machine while being operated, and to discharge them to the outside of the machine.

In this reaper, in order to maintain the ground and height of the reaping transport section, a ground tower is installed below the reaping transport section. However, in the past, ground bridge bodies were provided below both the left and right ends of this reaping conveyance section, so if the field area is relatively flat and has few irregularities, the reaping conveyance section However, if there are many irregularities, the left and right ground towers will follow the irregularities, making it easier for the reaping conveyor to swing from side to side. Sometimes the cutting height was uneven. In particular, with this type of reaper, the harvested husks are fed into the threshing machine for threshing, so only the tip side of the ear is often cut as short as possible, so the reaping conveyance section is moved from side to side as shown above. If the cutting height changes as the cutting height changes, it may result in cutting too short and cutting off the grain-bearing part, or conversely, cutting too long and cutting the base of the plant unnecessarily longer than the grain-bearing part. Next thing to do.

Furthermore, if the ground contact conditions of the left and right ground towers differ, there will be a difference in ground propulsion resistance, which may cause the aircraft to meander.

In addition, in conventional reapers, both the height of the grounding tower and the height of the wheels are fixed, or only the height of the grounding tower can be adjusted. There are few adjustable methods for ground height, and in the case of extremely short or long culms, the tip side cannot be cut to the desired length, and the range of culm lengths that can be harvested is relatively narrow. Furthermore, since the only way to deal with the rolling of wheels in wet rice fields was to replace them with larger-diameter wheels, the problem was that they could not be used under adverse conditions such as extremely wet rice fields. Conventional pruning machines have the drawback of being able to perform adequately only under relatively favorable crop and field conditions.

The present invention eliminates the above-mentioned drawbacks of conventional machines and provides a walk-behind reaping machine that can perform efficient reaping and harvest under a wide range of crop and field conditions. It is aimed at seven people.

The present invention provides a reaping conveyance section equipped with a reaping device and a reaped husk lateral conveyance device at the front of the machine, and an engine and a control noddle at the rear of the machine, which are located between the reaping conveyance section and the engine. A walk-behind reaper is provided with wheels, and the wheels are pivotally supported on the front part of a wheel transmission case that can be vertically oscillated and fixed centering on the engine side, and Lower left and right center VC
It is characterized by having long/wooden ground towers arranged at the front and rear, the height of which can be adjusted freely.

In other words, since the /wood grounding tower is installed below the left and right center of the reaping transport section, even if there is a height difference between the left and right ground below the reaping transport due to unevenness in the field, the /wood grounding tower The reaping and transporting section supported by the mower does not sway from side to side, making it possible to steer more stably from side to side than with conventional machines with grounding towers on the left and right.

In addition, there is no meandering phenomenon caused by the difference in ground resistance between the left and right tower bodies, and it is now possible to run with excellent straightness.

In addition, the height of the ground turret and the wheels can be adjusted independently, so by adjusting both in the opposite direction, the height of the reaping transport section can be adjusted over a wide range, making it suitable for a wide range of applications from short to long culms. 17) It is possible to reap the desired cutting length, and
By lowering the reaping conveyance unit sufficiently, it became possible to reap large lodging culms.

In addition, since the wheels can be lowered, it has become possible to introduce the reaper into extremely wet fields where the wheels are severely submerged.

In short, the wood sucker can perform efficient cutting and harvesting operations under a wide range of crop and field conditions.
