Description

Description: TECHNICAL FIELD The present invention relates to a frame structure of a threshing machine.

(Prior art)

Conventionally, as a frame structure of a threshing machine, there is a lack of strength in a front side plate of a handling room in which a handling drum is internally mounted and particularly a strength of a rear side plate on an outlet side, and various reinforcing means have been taken to cope with this. .

For example, Japanese Utility Model Application Laid-Open No. 55-37326 discloses a means in which one end of a rear plate of a handling room is extended outward and is fixed to a fryer cylinder fixed to an airframe. As disclosed in JP-A-62-116647, the strength is increased by connecting the front and rear side plates of the handling room with a reinforcing member and fixing and supporting this reinforcing member to an orthogonal reinforcing frame connecting the front and rear side plates at the rear of the fuselage. Is already known.

[Problems to be solved by the invention]

However, in the former technique, the strength of the front side plate is not solved, and the shape of the side plate is complicated. In the latter case, since the orthogonal reinforcing frame is required, the weight of the machine becomes heavy, and the maintenance work is poor, such as the need for cleaning due to accumulation of grains and straw chips on the orthogonal reinforcing frame.

[Means for solving the problem]

That is, the present invention provides a frame structure of a threshing machine which can increase the rigidity of the threshing frame while being lightweight, and has taken the following technical means.

That is, the front side plate 6 of the handling room 2 on which the handling cylinder 1 is mounted on the interior shaft and the fryer cylinder 19 fixed to the machine body are connected via the reinforcing pipe 20 along the vicinity of the left side wall 9b of the handling room 2, Rear panel 7 of handling room 2
And between the reinforcing pipe 20 or the fryer 19 via a reinforcing member 23, and the reinforcing member 23 is configured to support a counter shaft 25 for driving the processing cylinder. Frame structure of the threshing machine.

〔The invention's effect〕

Since the front plate 6 and the rear plate 7 of the handling room and the fryer cylinder 19 fixed to the machine body are connected and held together through the reinforcing pipes 20 and the reinforcing members 23, the threshing is achieved while being light in weight. This leads to an increase in the rigidity of the frame, which can be strongly reinforced. In addition, since the reinforcing member 23 of the rear plate 7 is used as a bearing member of the counter shaft 25 for driving the processing cylinder, no special supporting member is required. The structure can be simplified while securing sufficient strength.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a handling cylinder, 2 denotes a handling chamber in which the handling cylinder 1 is mounted on an interior shaft, and the upper portion is surrounded by a handling cylinder cover 3 and the lower portion is surrounded by a receiving net 4. A dust outlet 5 is opened at the end of the handling chamber 2 in the axial direction of the handling cylinder axis.

Reference numeral 6 denotes a front side plate of the handling room 2, reference numeral 7 denotes a rear side plate, and reference numeral 8 denotes a middle side plate. These side plates 6, 7, 8 are connected at one end by left side plates 9a, 9b. The mouth 10 for inserting the tip of the grain stem into the handling room 2 is provided in the feed chain 11 of the left and right side plates of the handling room 2.
It is formed along the lower edge of the right side plate 12 on the side where there is.

A processing chamber 13 is provided in a portion extending from a portion corresponding to the dust outlet 5 of the handling room 2 to a rear portion of the handling room 2. This processing room
A processing cylinder 14 is mounted on the shaft 13, and the processing chamber 13 is provided with an outer cover 15.
And the inner processing net 16. At the end side of the processing chamber 13, a dust discharge port 18 for discharging a dust-discharged material onto a swinging sorting shelf 17 below is opened and provided.

The front side plate 6 of the handling room 2 is provided with a channel type stay via a reinforcing pipe 20 extending along the vicinity of the left side wall 9b in a first-stage fryer cylinder 19 vertically erected from the lower end of the body of the threshing machine. The rear side plate 7 is connected to the staying cylinder 19 via the plate-like reinforcing member 23 provided on an extension of the stay 21 with the stay 21 by integrally connecting and fixing with a fastener such as 21 and a bolt 22. It is connected and fixed with bolts 22. The rear side plate 7 is connected and fixed to the above-mentioned fryer cylinder 19 via another reinforcing member 24 at a position below the processing chamber 13.

A counter shaft 25 for driving the processing drum 14 is suspended between the reinforcing member 23 and the middle plate 8. Pulley 26 provided at one end of counter shaft 25 and handle shaft 1A
A belt 28 is wound between pulleys 27 provided on the
The chain 31 is stretched between a sprocket 29 provided on the other end of the cylinder 25 and a sprocket 30 provided on the processing cylinder shaft 14A, and
In order to rotationally drive the processing cylinder 14, a cooperative configuration is provided.

The transmission mechanism to the handle cylinder 1 includes the other end of a shaft 33 provided with an input pulley 32 at one end, and the other end of a shaft 36 at one end linked to the handle cylinder shaft 1A via bevel gears 34 and 35. The transmission 37 is interposed therebetween.

Among the thresh processed in the handling room 2 by the rotation of the handling cylinder 1, straw chips, broken ears and the like enter the processing chamber 13 from the dust outlet 5 to the end side of the handling chamber 2, Treated with a treatment net 16 while being transported axially by 14; and
Single grain and finely divided straw waste are treated
From the lower part of the swinging sorting shelf 17, and large particles such as straw waste that cannot leak through the processing net 16 are discharged into the processing chamber 13.
Is discharged from the dust outlet 18 onto the swinging sorting shelf 17 below.

The handling cylinder 1 and the processing cylinder 14 rotate in the same direction.
By making the peripheral speed at the tip end of B higher than the peripheral speed of the tip end of tooth handling 1B, the processing object is smoothly transferred from the handling cylinder 1 to the processing cylinder 14 at the dust outlet 5. .

In the drawing, reference numeral 38 denotes a suction cross flow fan, 39 denotes a pressurized air fan, 40 denotes a swing sorting net, 41 denotes a first gutter, and 42 denotes a second gutter.
