Description

[Detailed description of the invention] [Field of industrial application] The present invention provides a handling chamber that pivotally supports a handling cylinder that is driven for lower handling, and a processing chamber that pivotally supports a processing cylinder that is driven in the opposite direction to the handling cylinder. and are arranged in parallel with the feed chain, and an opening is formed that communicates the two chambers over substantially the entire length thereof, and the threshing material in the handling chamber is sent into the processing chamber through the opening. Therefore, even if the amount of grain culm supplied into the handling chamber increases, the increased amount of grain culm can be introduced into the processing chamber through the opening that communicates the two chambers. This prevents a portion of the threshing drum from being pressed against the gap between the handling drum and the receiving net located below the handling drum, which prevents the handling action of the handling teeth from being sufficiently effective, resulting in unhandled items. This article relates to a threshing device that can improve processing capacity.

[Prior art]

In this type of threshing device, the receiving nets stretched over the lower portions of the handling chamber and the processing chamber are arc-shaped and concentric with the handling and processing cylinders, respectively.

[Problem that the invention attempts to solve]

Because of this concentric circular arc shape, for the processed material that is sent from the lower part of the processing chamber toward the upper part of the processing chamber, the processed material that is rotationally driven by the processing cylinder is transferred to the receiving screen terminal on the processing chamber side. Because of the shape of the part, the material will be sent upwards into the processing chamber, and its direction will impede the flow of the material into the processing chamber, which will hinder the flow of the material from the processing chamber to the processing chamber. There was a risk that the smoothness of the process would be hindered.

An object of the present invention is to provide a device that can more smoothly transport the processed material from the handling chamber to the processing chamber by making simple modifications to the receiving net.

[Means to solve the problem]

The characteristic configuration according to the present invention is that the terminal end portion of the receiving net stretched in the lower part of the processing chamber facing the opening is bulged downward, and the terminal portion of the receiving net in the handling room and the terminal portion facing the opening of the receiving net in the handling room are bulged downward. It is located at a point where the angle of intersection between the two is made small, and its effects are as follows.

[Effect]

In other words, by focusing on the fact that the direction in which the material to be processed is sent out is related to the shape of the receiving net, by bulging the terminal end of the receiving net on the processing chamber side downward, the material is sent out toward the processing room. The direction in which the material to be processed is sent out is directed upward from the opening or above the processing chamber, and the intersection angle between the processing chamber and the processing material sent from the processing chamber can be made small, and the delivery action from the processing chamber to the processing chamber can be reduced. This can be done much more smoothly than the conventional configuration with a large intersection angle.

[Effect of idea]

A simple modification of forming a downward bulge at the end of the receiving net on the processing chamber side allows for smooth delivery of the processed material from the processing chamber to the processing chamber. We have now been able to provide a product that allows for efficient handling under appropriate loads and improves overall threshing efficiency.

〔Example〕

As shown in FIG. 1, a handling chamber 2 and a processing chamber 3 having an inlet 3a of the second reduced material are installed in parallel with the feed chain 1, and are built therein for pre-handling drive, and
The handling cylinder 4 with handling teeth 4a and the processing cylinder 5 with handling teeth 5a, which are driven in mutually opposite directions, are arranged side by side in a state in which their axes are parallel to each other, and the bottoms of both chambers 2 and 3 are arranged side by side. A swing sorting device 6 is disposed on the side in a sorting chamber 7, and a winnow 9 and a dust exhaust fan 8 for generating sorting air in the sorting chamber 7, and a carry-out screw 1 are provided.
A threshing device is provided with a sorted first item recovery section 10 equipped with a sorting screw 0a, a sorted second item recovery section 11 equipped with a carry-out screw 11a, and a thrower 12 that sends the collected second item to the entrance 3a of the processing chamber 3. has been configured.

An opening 14 is formed that communicates the handling chamber 2 and the processing chamber 3 over substantially the entire length thereof, and the material to be processed in the handling chamber 2 is sent into the processing chamber 3 through this opening 14. Even if the amount of grain supplied to the handling room 2 increases and a large amount of threshed material is produced, it is immediately sent to the processing room 3 to eliminate accumulation in the handling room 2 and eliminate "unhandled" and "hulled paddy". ” phenomenon can be reduced. In addition, on the inner wall surface of the processing chamber 3, receiving teeth 13 are provided in the handling teeth 5a implanted in the processing cylinder 5 in a staggered manner when viewed from the circumferential direction on both sides of the handling teeth 5a, to provide strong handling. It is designed to work,
As a result, the threshed material, which has not been sufficiently handled due to the short residence time in the handling chamber 2, can be sufficiently single-grained in the treatment chamber 3.

The terminal portion 1 facing the opening 14 of the receiving net 15 stretched at the lower part of the processing chamber 3 having the above-described configuration.
5A bulges downward, and this receiving net 15 terminal portion 1
5A and the end portion 16A facing the opening 14 of the receiving screen 16 of the handling chamber 2 is made small, so that the material to be processed from the processing chamber 3 is transferred from the handling chamber 2 to the processing chamber 3. It is possible to reduce the degree of resistance to the feeding of the processed material.

Further, with respect to the bulged terminal end portion 15A of the receiving net, a processing material guide plate is installed at a position away from the rotation locus of the handling teeth 5a of the processing cylinder 5 and in a state inclined with respect to the axis of the processing cylinder 5. 17 are arranged in parallel, and the material to be processed can be transferred to the terminal end of the processing cylinder 5 in the same way as the processing cylinder 4.

This type of threshing device is used in machines equipped with a threshing device, such as combines and harvesters.
