Description

  The present invention relates to a configuration of a threshing apparatus such as a combine or a harvester.

Conventionally, in this type of threshing apparatus, a processing object including a grain that has been provided with a dust feeding port leading to a processing chamber provided with a processing cylinder at a terminal portion of a processing chamber provided with a processing cylinder and that could not be processed in the processing chamber. It is known to improve the threshing performance by sending it into the processing chamber through the dust outlet and reprocessing in the processing chamber. There was a problem that an object stuck in the transporting cereal and discharged to the outside without being recovered as it was.
Therefore, a rotating body is provided on the barrel shaft immediately after the handling chamber, and the rotating body is brought into contact with the threshed transported cereal outside the handling chamber to collect the scorpion grains contained in the transported cereal. The technique to do is already known (for example, refer patent document 1).
JP 2002-136216 A (FIGS. 6 to 8)

However, since the thing of the said patent document 1 tries to collect | recover a stabbed grain after providing a rotary body outside a handling chamber and having stabbed the grain in a conveyance cereal, the stabbed grain is collect | recovered. There was a problem that could not be solved.
In addition, since the processed material that does not fully enter the dust feed port stays at the end of the handling chamber, not only does the treated material circulate in the handling chamber and increase the load on the handling cylinder, but There was a problem that it became a mass and dropped onto the rocking sorter, which lowered the sorting accuracy.
The subject of this invention exists in the point which improves the said malfunction.

  In order to achieve the above object, in the present invention, a threshing apparatus is provided with a dust feed port leading to a treatment chamber provided with a treatment cylinder at a terminal end portion of the treatment chamber provided with a treatment drum. A first feature is that a rotating body is provided in the vicinity of the lower side of the body rotation direction so as to forcibly spill the sawdust and the like toward the processing chamber.

  A second feature is that the peripheral speed of the rotating body is made faster than the peripheral speed of the handling cylinder.

  Furthermore, a third feature is that the rotating body is formed of a brush-like elastic body.

A rotating body that forcibly ejects the processed material toward the processing chamber is provided near the lower side of the dust feeding port in the rotation direction of the processing cylinder, so that the processed material sent to the end of the processing chamber can be efficiently processed. It is possible to prevent the processed material from staying at the end of the handling room or being stuck in the transporting culm and being transported out of the machine as it is. It is understood that the threshing performance is improved.
Further, since the peripheral speed of the rotating body is made higher than the peripheral speed of the handling cylinder, the processing object can be ejected more efficiently and the processing object can be efficiently fed into the processing chamber.
Furthermore, since the rotating body is made of a brush-like elastic body, there is no hindrance to the rotation of the barrel even if the rotating body comes into contact with the handle, and the rotating body can be approached to the handle and the teeth. It is possible to efficiently eject the processed material that has not entered the mouth to the processing chamber.

  A threshing device provided with a dust feed port leading to a treatment chamber provided with a treatment cylinder at a terminal end portion of the treatment chamber provided with a treatment drum, in the vicinity of the dust feed port on the lower side in the rotation direction of the treatment drum, A rotating body made of a brush-like elastic body jumping toward the processing chamber was provided, and the peripheral speed of the rotating body was made faster than the peripheral speed of the handling cylinder.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a plan view of a main part of a threshing apparatus employed in a self-removing combine that employs the present invention.
That is, 1 is a threshing device, 2 is a handling chamber surrounded by the surroundings, and a handling cylinder 5 in which a handling cylinder 3 is spanned from the front wall 4a to the rear wall 4b in the handling chamber 2. A large number of teeth 6... For threshing cereal grains that are to be removed are planted on the peripheral surface.
A dust delivery port 8 (see FIG. 2) is provided on the terminal side of the handling chamber 2 so as to extend to the rear side of the handling chamber 2 and communicate with the processing chamber 7. Is provided with a rotating body 10 provided with a large number of brush-like elastic bodies 9 around it.

In the processing chamber 7, a processing cylinder 13 in which a large number of processing teeth 12... Are implanted around the processing chamber 7 is rotatably supported like the handling cylinder 3.
Here, 14 is a feed chain that sandwiches the stock side of the cereal that is to be cerealed and transports it from the front to the back, and 15 nips the threshed waste that has been taken over from the feed chain 14 to thresh. It is a waste transporting device for transporting toward the rear center side of the device 1.

  Further, a pulley 16 is provided at the end portion of the handling cylinder shaft 5, and power is transmitted to a pulley 19 provided on the shaft 18 of the rotating body 10 via a belt 17 so that the rotating body 10 can handle the handling cylinder. 3 is configured to rotate in the same direction as 3.

Next, FIG. 2 is a rear view of the main part for explanation of the threshing device, and shows the positional relationship between the handling cylinder 3, the rotating body 10, and the processing cylinder 13. FIG.
In the figure, there is a dust feeding port 8 between the handling chamber 2 and the side processing chamber 7 that follows this, and the rotating body 10 is provided at a position near the lower side in the rotation direction of the handling cylinder 3 of the dust feeding port 8. When viewed in the rear view (front view) in the figure, the rotation locus 3a drawn by the tip of the tooth handling 6 on the handle barrel 3 side and the rotation locus 10a drawn by the tip of the elastic body 9 on the rotating body 10 side are wrapped. Further, the peripheral speed of the elastic body 9 portion of the rotating body 10 is set to be higher than the peripheral speed of the tooth handling portion 6 of the handle 3 so that the processed material is not clogged by this portion. It is configured to be surely ejected to the chamber 7 side.

  Further, the positional relationship between the handling cylinder 3 and the rotating body 10 is such that the rotation of both ends of the straight line L connecting the handling cylinder shaft 5 serving as the axis of the handling cylinder 3 and the shaft 18 serving as the axis of the rotating body 10. The dust delivery port 8 is configured to be positioned in the direction of the perpendicular H from the lap portion of the movement locus.

  Further, the brush-like elastic body 9 on the peripheral surface of the rotating body 10 reduces the impact even when both teeth come into contact with each other due to the rotation of the tooth handling 6 on the peripheral surface of the handling cylinder 3, thereby preventing any rotation. In addition, the momentum for removing the dust and the like by the elastic force of the elastic body 9 is increased, and the working efficiency is improved.

Furthermore, since the rotating body 10 is provided only at the position of the dust feed port 8 at the end of the handling chamber 2, the structure can be made compact.
A chain line at the bottom of the handling cylinder 3 indicates the handling net 20, and a chain line around the processing cylinder 13 indicates the second handling net 21.

  Since the present invention is composed of the above-described configuration, the harvested cereal culm that is to be cerealed is conveyed while the stock source side is sandwiched and conveyed by the feed chain 14 on the side of the threshing device 1. The tip of the cereal is threshed by the tooth handling 6 of the barrel 3 that rotates in the handling chamber 2, and is rejected beyond the rear wall 4 b at the rear of the handling chamber 2. Thus, it is discharged to the rear of the threshing device 1.

  In addition, the processed product that has been threshed in the handling chamber 2 leaks from the handling net 20 below the handling chamber 2 and is sorted in the sorting chamber below, but the treated product that has not leaked from the handling net 20. Is gradually moved backward in the handling chamber 2 while being loosened by the rotation of the handling cylinder 3, transferred to the processing chamber 7 from the dust feed port 8 at the end of the handling chamber 2, and again the processing cylinder. 13, the grain in the processed material leaks from the second handling net 21 and is sorted in the lower sorting chamber, and the remaining cuttings and sawdust are not shown in the figure. It is discharged out of the machine together with dust by a dust exhaust device at the rear of the sorting chamber.

  At that time, the processed material that has not entered the dust feed port 8 tends to be carried around by the rotation of the handling cylinder 3, but the rotating body 10 provided near the lower side in the rotation direction of the handling cylinder 3 of the dust feed port 8. However, since the treatment object carried by the handling cylinder 3 is forcibly ejected to the treatment chamber 7 side, the treatment object sent to the terminal end of the treatment chamber 2 can be efficiently fed into the treatment chamber 7. It is possible to prevent the processed material from being carried around at the end of the handling chamber 2 and staying in the conveying chamber 2 and being transported to the outside of the machine as it is. Threshing performance is improved because it is solved by vigorously colliding from the facing direction.

It is a top view of the principal part of a threshing apparatus. It is a rear view of the principal part for explanation of a threshing apparatus.
