Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a full-culm input type combine harvester equipped with an axial flow type threshing device.

[Prior art and problems]

Generally, in the axial flow type threshing device of this type of combine, the entire grain culm supplied into the handling chamber is directed from the supply port side (front end side) to the discharge port side (rear end side) of the handling chamber by a spiral handling cylinder. The grains are threshed between the receiving net and the receiving net, and the threshed grains are
It leaks from the receiving net to the sorting section below, but the threshed culms such as culm waste are discharged to the outside from the discharge port at the rear end of the handling chamber. The second material from the sorting section is returned to the processing chamber installed on the side of the processing chamber for reprocessing, and the first material is stored in a grain tank located outside the processing chamber. We are trying to accommodate them. However, in the past, the No. 1 lifting cylinder to the grain tank and the No. 2 return cylinder to the processing chamber were both interposed between the processing chamber and the grain tank, so the grain tank could only be processed so much. The problem was that it was not possible to get it close to the room, the width of the aircraft was large, the overall size was large, and it was impossible to make it compact.

The present invention aims to solve these problems and takes the following technical measures. .

[Means for solving problems]

That is, the technical means according to the present invention is a handling chamber 5 in which a long handling cylinder 6 is mounted on an internal shaft along the front-rear direction.
A processing chamber 10 having a processing cylinder 9 configured to be shorter on the rear end side than the processing cylinder is arranged side by side above the processing cylinder, and a grain tank 21 is arranged on the lateral outer side of the processing chamber. A second reducing cylinder 22 to the processing chamber is erected in the rear space of the processing chamber, and the first grain reducing cylinder 20 is inclined toward the front end side through the lower space of the processing chamber 10 and connected to the grain tank 21. It is characterized in that it is configured to communicate.

[Effect]

When the entire harvested crop is inputted from the reaping section and fed into the handling chamber 5, the threshed grains are passed through the handling chamber 5 by the handling cylinder 6 from the supply port 3 side at the front end to the discharge port 4 at the rear end side in the axial direction. While being transported to the side, the grains are threshed between them and the receiving net 1. Then, among the threshed grains leaking from the receiving net 1, the grains are sorted and transferred to the first receiving gutter 18.
The No. 1 grain stored in the tank is taken out of the machine by the No. 1 lifting cylinder 20 and stored in the tank 21, but the No. 1 grain is
The product passes through the No. 2 receiving gutter 19 and the No. 2 reduction cylinder 22,
Grain is returned to the rear end of the processing chamber 10, and is processed between the receiving net 11 while being sent to the front end by the processing cylinder 9, and the grains leaking from the receiving net 11 are sent to the sorting room below the handling chamber. The culm waste and the like containing untreated substances that are dropped and do not leak are returned to the handling chamber 5 and reprocessed.

[Effect of idea]

In summary, according to the present invention, the processing chamber has a processing chamber whose rear end is shorter than the processing cylinder, which is located above the processing chamber in which a long processing cylinder is mounted along the longitudinal direction. In an axial flow type threshing device with parallel chambers, the No. 1 lifting cylinder is placed in the space below the processing chamber, and the No. 2 reducing cylinder is installed upright in the rear space of the processing chamber. The grain tank, which is placed on the side of the machine, can be placed close to the side wall of the processing chamber, making it possible to maintain sufficient tank capacity while reducing the width of the machine and making it more compact.

〔Example〕

An embodiment of the present invention will be described below based on the drawings. The rear of the machine, which is equipped with a running body crawler, is equipped with an axial flow type threshing device B, which will be described later, and the front of the machine is equipped with a feeder that reaps the crops to be planted in the field and supplies the entire amount to the threshing device B. A reaping station A is equipped with A1.

The threshing device B has the following configuration. That is, a receiving net 1 is stretched along the lower half circumference, the upper part is covered with a cover 2, and a supply port 3 is provided on the front side. It consists of a handling chamber 5 provided with a discharge port 4 on the rear side, and a handling cylinder 6 elongated in the front-rear direction and mounted on an internal shaft in the handling chamber. A spiral body 7 is wound around the outer peripheral surface of the handling barrel 6 to thresh the grain between the receiving net 1 and the receiving net 1 while transferring the grain from the stalk culm supply port 3 side to the discharge port 4 side of the handling chamber. The grains and the like that have been threshed in the handling chamber 5 leak through the receiving net 1 and fall into the sorting chamber 8 below, where they are sorted. Threshed culms such as culm waste are transferred to the terminal end of the handling chamber 5 and discharged to the outside from the discharge port 4.

A processing chamber 10 having a processing cylinder 9 configured to be shorter on the rear end side than the processing cylinder 6 is arranged side by side above the processing chamber 5.
The second grain that is returned to the rear end side is sent to the front end side by the processing cylinder 9 and is processed between it and the receiving net 11, and the grains leaking from the receiving net 11 are passed through the flow plate 12 to the lower part of the handling room. The culm waste and the like containing unprocessed materials that do not leak through the receiving net 11 are sent into the handling chamber 5 through the communication port 13 to be reprocessed.

The sorting room 8 below the handling room 5 includes a swinging sieve sorting device 14 for receiving the threshed material (material to be sorted) leaking from the receiving net 1 and sorting it through a swinging sieve, and a wind sorting device using a pressure fan 15. At the bottom of the route, the first downstream shelf 16. Screw conveyor 18a, 1 that receives and accommodates the grain flowing down through the second downstream shelf 17
A first receiving gutter 18 and a second receiving gutter 19 with 9a are provided, respectively. The No. 1 lifting grain cylinder 20 with a screw conveyor 20a connected to the transfer end portion of the No. 1 receiving trough 18 is inclined toward the front end through the lower space of the processing chamber 10 and extends to the front of the processing chamber. , and is configured to communicate with the grain tank 21 so that the first material discharged from the first port 20b at the tip thereof is accommodated in a grain tank 21 disposed on the lateral side of the processing chamber 10. A No. 2 reducing tube 22 with a screw conveyor 22a connected to the transfer terminal end of the No. 2 receiving gutter 19 is erected at a position in the rear space within the width of the processing chamber 10, and a No. 2 reducing port at the tip thereof is installed. It is configured to communicate so that the second material discharged from 22b is returned to the rear end of the processing chamber 10.

In addition, at the rear end side side part of the processing chamber 5,
In the rear space of the grain tank 21, an engine 23 and a reduction gear case 24 are arranged.
