Description

[Detailed Description of the Invention] The present invention relates to a grain culm conveying device in the reaping section of a DC combine harvester, and is configured to smoothly convey the harvested grain culm.

By the way, the conveying device for the harvested grain culm in a DC type combine harvester uses a horizontal feed auger to collect the grain culm whose root part has been harvested by a cutting blade to the center or one side of the machine body, and then to handle it by a vertical conveyor. The grain culms are transported into the handling room, but in order to always supply the grain culms to the handling room with the ears in a leading position, the grain culms that have been harvested at the base of the stock and are laid down are placed between the cutting blade and the horizontal feed auger. It is equipped with an auxiliary conveyor that receives the ears with the tips facing backwards and delivers them to the auger. However, this auxiliary conveyor
In the vertical direction, an extremely short dimension from the cutting blade to the auger is sufficient, but in the horizontal direction, a dimension approximately equal to the cutting width is required, so in the past, multiple conveyors were used side by side. However, in this case, a gap is created between adjacent conveyors, and the conveying action does not reach the grain culms that lie down in the gap, resulting in turbulence in the flow of the harvested grain culms. As a result, the posture of the grain culms carried into the handling room becomes uneven, and the threshing process is not carried out properly.

The present invention addresses the above-mentioned problems, and is applied to the reaping section of a DC combine harvester in which a plurality of auxiliary conveyors are arranged horizontally between the cutting blade and the cross-feeding auger installed horizontally behind it. A separating guide member is provided in the gap between each of the above-mentioned conveyors, and the separation guide member expands from the forwardly protruding sharp end of the cutting blade to the upper position of the conveyors on both sides. The harvested grain culms are harvested while being separated into left and right sides, and placed securely on the conveyors on both sides. This ensures that all the harvested grain culms are uniformly delivered to the cross-feeding auger with the ears facing backwards. The flow of the grain culm is made smooth, and as a result, the threshing process in the threshing machine is performed well.

Hereinafter, this will be explained with reference to an embodiment shown in the drawings. In FIG. The lower part or rear part thereof is used as a sorting part for first and second grains separated from the grain culms, straw waste, etc., and the rear part is used as a straw discharge part. Reference numeral 4 denotes a reaping section installed at the front of the threshing machine. An auxiliary conveyor 8 is disposed behind the auxiliary conveyor 8, and a transverse auger 9 is disposed further behind the auger, and a vertical conveyor 10 is disposed from behind the auger to the entrance of the handling chamber 3 of the threshing machine. .
However, the auxiliary conveyor 8 has a structure in which two conveyors 8a and 8b are arranged side by side as shown in FIG. Sharp end part 1 protruding from
A separation guide member 11 is provided that expands from side to side from 1a to a position above both conveyors.
In the embodiment shown here, the member 11 is formed in the shape of a rod and is fixedly supported by a floor plate 12. As shown in FIG. Further, in this embodiment, similar guide members 13, 13 are provided for gaps B, B, which are formed between the outer side ends of each conveyor and the dividers 5, 5.

According to the above configuration, the grain culm planted in front of the reaping section 4 is harvested at its base by the cutting blade 7 as the machine moves forward, but in this case, the gap between the auxiliary conveyors 8a and 8b is The grain culms planted in the front of section A are harvested while being separated to the left and right by the separation guide member 11, and when they are further laid down to the rear, they are guided by this member and are reliably placed on the conveyors 8a, 8b on both sides. In addition, in the illustrated embodiment, the grain culms planted in front of the gap B between the outer side ends of the conveyors 8a and 8b and the dividers 5 and 5 are also reliably placed by the guide members 13 and 13. In this way, all the reaped grain culms are received on the conveyors 8a and 8b in the posture in which they are laid down, that is, with the tips facing backwards, and the conveyors uniformly transfer them to the cross-feeding auger. 9, and further carried into the handling chamber 3 of the threshing machine 1 by the vertical conveyor 10 while maintaining that posture.

As described above, the present invention provides a cutting section in which a plurality of auxiliary conveyors are arranged side by side between the cutting blade and the transverse feed auger behind the cutting blade. Since the structure is equipped with a separation guide member that expands left and right from the forward-protruding sharp end to the upper position of both conveyors, all harvested grain culms are securely placed on the auxiliary conveyor with the ears facing backward. As a result, the reaped grain culm is smoothly conveyed in the above-mentioned position, and the threshing process can be performed satisfactorily.
