Description

[Detailed description of the invention] The present invention relates to a sugarcane harvester.

When collecting sugarcane planted in a field, there are two methods: one is to collect the culms by cutting them into pieces, and the other is to collect the culms as long culms without cutting them into pieces.

Conventionally, there is a technique disclosed in Japanese Patent Publication No. 49-26338 and Japanese Patent Application Laid-Open No. 55-48318 as a method of recovering culms by cutting them into pieces.

The structure disclosed in Japanese Patent Publication No. 49-26338 is
The structure that discharges the shredded culm outside the machine and collects it afterwards, and the structure disclosed in Japanese Patent Application Laid-Open No. 55-48318, has a structure that collects the shredded culm in a hopper. Of things.

Those with a structure that discharges the shredded culm are troublesome to collect the culm afterwards, and those with a structure that collects the shredded culm into a hopper are difficult due to engine horsepower. The hopper cannot be made very large, and therefore the machine must be frequently moved to the edge of the field and transferred to a transport vehicle, which is disadvantageous and leads to a reduction in reaping work.

In addition, in any case, in the type of collection in which the culm is shredded, the sugar content increases due to the exposure of the cut end to the air, compared to the type in which the culm is collected without being shredded. The disadvantage was that the sugar was oxidized and turned into invert sugar, resulting in poor yield.

As a method of recovering long culms without cutting them into pieces, there is a technique disclosed in Japanese Patent Publication No. 52-23946.

With this structure, the roots of the sugarcane to be planted are cut, the leaves are removed without cutting the culm into pieces, and the long culms are collected as they are. Since the structure is such that the culms are discharged to the side and the leaves are conveyed to the rear of the machine, if the culms are discharged outside the machine as they are, the detached leaves may be placed on top of the previously discharged culms during round-cutting work. As a result, the culm has to be recovered from inside the detached leaves, which makes subsequent recovery of the culm troublesome.In order to avoid this, in the case of this structure, a culm recovery device is installed at the rear of the aircraft. A loading platform is provided.

However, the structure with a loading platform has the disadvantage of increasing the size of the aircraft, and the structure in which the culms are accumulated on the loading platform cannot make the loading platform very large due to engine horsepower. However, it was necessary to frequently move the machine to the edge of the field and transfer it to a transport vehicle, which was an inconvenience and resulted in a reduction in harvesting work.

The first invention does not require a loading platform, and
To facilitate collection of culms by using a long culm collection format that is easier to collect culms than a format in which culms are collected by cutting them into pieces.

In addition to the object of the first invention, the second invention aims to improve the separation between culms and fallen leaves.

To achieve the above object, the first invention features a cutting device that cuts the root of sugarcane to be planted, and a cutting device that removes leaves from the culm of unshredded sugarcane whose root has been cut. A defoliation device, a conveyance device that conveys a conveyed object consisting of defoliated culms and detached leaves to the rear of the machine, and a blower that blows sorting air onto the conveyed object conveyed by the conveyance device are provided. The sugarcane harvesting machine is such that the conveying surface of the conveying device faces into the exhaust air passage of the blower at a rearward position of the conveying end of the conveying device, and the conveyed material inherited from the conveying device is transferred toward the lateral side of the machine body. This is because a discharge device is provided, and this configuration provides the following effects.

In other words, since the detached leaves are released to the rear of the machine and the culms are released to the side of the machine, if you mow around so that the release direction of the culms is on the already-cut side, the detached leaves that have already been released will be released. Since the culm is released upward, it becomes easy to collect the culm from now on.

In addition, since the culms released onto the detached leaves are long culms, the collection work is easier than with shredded culms.

Then, like this, put the breakaway leaf behind the aircraft,
By discharging the culms to the sides of the machine, subsequent collection of the culms becomes easier, allowing continuous reaping work to be carried out without the need for a loading platform.
This does not lead to an increase in the size of the aircraft.

To achieve the above object, the feature of the second invention includes a cutting device that cuts the root of the sugarcane to be planted, and a cutting device that removes leaves from the culm of the unshredded sugarcane whose root has been cut. A defoliation device, a conveyance device that conveys a conveyed object consisting of defoliated culms and detached leaves to the rear of the machine, and a blower that blows sorting air onto the conveyed object conveyed by the conveyance device are provided. The sugarcane harvesting machine is such that the conveying surface of the conveying device faces into the exhaust air passage of the blower at a rearward position of the conveying end of the conveying device, and the conveyed material inherited from the conveying device is transferred toward the lateral side of the machine body. A discharge device is provided, and a second blower is further provided to blow away the remaining detached leaves discharged together with the culm from the terminal end of the discharge device toward the rear of the machine body, and this configuration provides the following effects.

That is, this invention has the same effects as the first invention, but in particular, by providing the second blower, the sugarcane can be sorted into detached leaves that are easy to separate from the sugarcane falling toward the field. By applying wind, the detached leaves that could not be separated by the first blower can be effectively separated, and the separation between the culm and detached leaves can be improved, and the culms and detached leaves are released without being separated. There is no need for the subsequent culm collection work to become troublesome.
