Abstract

PURPOSE:To separate reaped straw from unreaped culm row and to reduce the threshing load, by attaching a straw-discharging plate to a second mower or its machine frame and guiding the reaped straw on a field toward the reaped part by the plate. CONSTITUTION:A thresher 3 is placed on a truck 2 having travelling device 1, a threshing chamber 9 is positioned at the top and a culm-charging port 11 is opened at the front side. A reaping and transfer apparatus 4 is positioned in front of the thresher 3 and has a grass-separating member furnished with a raking reel 13, a reaping device 10, a raking auger 7 and a conveyor 8 in a frame-worked state. The culm on a field is reaped and supplied to the threshing chamber 9. The 2nd reaping apparatus 5 is positioned at the back of the reaping and transfer apparatus 4, and a straw-discharging apparatus 6 is placed at the reaped field side to guide the cut straw to reaped field distant from the unreaped field. The straw-discharging apparatus 6 has e.g. a structure to blow the cut straw with a blower.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a second mower device in a combine harvester, and can be used in a conventional combine harvester.

PRIOR ART With conventional combine harvesters of this kind, there are times when the culm is cut at a high level rather than long due to the threshing load. Some have mowers.

However, this second mower only leaves the straw in the field, and especially near the uncut culms, the straw may enter the rows of uncut husks, which can be removed by cutting the culms. There was a defect that when the grains were fed into the handling room, they were also carried into the handling room, increasing the threshing load.

Problems to be Solved by the Invention The present invention aims to solve the above-mentioned deficiencies of the conventional type. By installing the board,
This aims to reduce the threshing load by keeping the mowed straw away from the rows of uncut husk culms.

Means for Solving the Problem The present invention takes the following technical means to achieve the above object. That is, a threshing machine 3 is mounted on a chassis 2 having a traveling device 1, and a reaping and conveying device 4 is mounted in front of it.
In the combine harvester equipped with, a second reaping device 5 for reaping short stubble is provided behind the reaping and conveying device 4,
This is a second mower device in which the second mower device 5 is provided with a straw removal device 6 that guides the harvested straw from all four sides of the field toward the already cut field.

Functions/Effects When the traveling device 1 is driven to move the chassis 2 forward to start work, the husks in the field are harvested by the reaping device 10 of the reaping and conveying device 4, and then transferred to the threshing machine 3 by the raking auger 7 and conveyor 8. It is supplied to the handling room 9.

During such work, the reaping device @10 often performs high cutting depending on the load on the handling chamber 9.

Then, the second reaping device 5 located behind the reaping and conveying device 4 moves forward while reaping the stump that was cut high to a low height.

At this time, the straw removal device 6 guides the cut straw on the field that is closer to the uncut land side to the already cut land side.

Therefore, the uncut husk culm is cut without straw and supplied to the handling chamber 9, so that the load on the handling chamber 9 can be maintained at a normal level.

The threshing machine 3 of this embodiment is mounted on a chassis 2'' having a traveling device 1, with a handling chamber 9 located at the top and a culm supply port 11 opened at the front side.

The reaping and conveying device 4 is located in front of the threshing machine 3, and is provided with a raking reel 13, a raking device 10, a raking auger 7, and a conveyor 8 in the grass cutting body, and cuts the grain culms in the field and transfers them to the handling room. 9.

The second reaping device @ 5 is installed behind the reaping and conveying device 4,
A straw removal device 6 is provided on the mowed field side, and the structure is such that the cut straw is guided far from the uncut field to the mowed field side.

In addition, various configurations can be considered for the straw removal device 6, such as a configuration in which cut straw is blown away by blowing air.
