Abstract

PURPOSE:To improve maintenance by forcing a screen frame itself for attachment of a concave screen 1 to vibrate toward the machine body side frame. CONSTITUTION:This thresher is composed of a concave screen 7 and a screen frame 10 respectively set under a threshing cylinder 2. The concave screen 7 is detachably attached to the screen frame and held thereby. The screen frame 10 is designed so as to be forced to perform reciprocating motion toward the machine body side frame in the circumferential direction of the threshing cylinder.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a threshing device.

[0002]

2. Description of the Related Art Conventionally, there is a net-receiving forced vibration device described in Japanese Patent Laid-Open No. 1-296917.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems of the prior art described in the above publication. Therefore, the following technical measures were taken.

[0004]

[Means for Solving the Problems] That is, the technical means according to the present invention comprises a receiving net 7 and a net frame 10 which are arranged below the handling cylinder 2, and the receiving net 7 is provided to the net frame. And is detachably attached and supported, and the mesh frame 10 is connected to the frame 1 on the machine body side.
8 is configured so as to be forcibly reciprocally oscillated along the circumferential direction of the handling cylinder.

[0005]

Therefore, in the prior art, since the net is forcedly vibrated with respect to the net frame, the maintainability was poor, but in the case of the present invention, the net frame is attached to the frame on the machine body side. Since it is forcibly vibrated, the maintainability is improved, and the problems of the related art can be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated example, a handling chamber 3 is framed by a front side plate 4, a rear side plate 5, a side frame 6 and the like, and inside the handling chamber 3 is rotated around one axis of the machine longitudinal direction. Torso 2
And a receiving net 7 is stretched along at least the lower half of the handling chamber. A feed chain 8 is stretched on one side of the handling room, and a picking rail 9 provided on the upper side of the feeding chain 8 holds and conveys the grain culms.

The receiving net 7 is divided into two parts, 7a and 7b, and is attached to the net frame 10 so as to be freely inserted and removed. The receiving nets 7a and 7b are configured to be separable from each other via a locking hole 11 and a locking pin 12, and a guide projection 13 provided on the receiving net 7a side and a locking hook 14 provided on the receiving net 7b side. Is a support rod 1 that connects the front and rear mesh frames 10a and 10b.
5 and 16 are configured to be engaged and retained.
The locking hook 14 is rotatable around the shaft 14a and is biased in the closing direction by a spring.

The net frames 10a and 10b are guide rollers in which guide portions 17 and 17 having a U-shaped cross section formed on the outer end sides of the net frames are pivotally supported by front and rear body side frames 18 and 18, respectively. By being guided and supported by 19, the net frame 10 and the receiving net 7 can be integrally swung along the circumferential direction of the handling cylinder 2. That is, the receiving net 7 is interlocked with the net frame 10 so as to swing together with the guide roller 19 and the forced vibration mechanism 20.

Generally, in a combine harvester, a grain tank GT is arranged on the lateral side of a threshing device. The grain tank GT has a structure as shown in FIGS. 4 to 6.
That is, the processing cylinder 2 for processing branch shoots while sending the paddy fed from the outlet 23 of the fried food container 22 having the fried food spiral 21 to the upper part of the Glen tank GT in the front-rear direction.
4 and a branch vessel processing device 27 including a processing chamber case 26 having a processing network 25 is installed. The processing cylinder 24 has processing teeth 28, and the processing chamber case 26 has fixed teeth 29. Reference numeral 30 indicates a discharge auger. By thus providing the branch stalk processing device in the tank, branch stalks are reduced, and since the paddy can be transported before and after the Glen tank by the processing drum, the filling rate of the paddy into the tank is increased.

Further, as shown in the figure, by constructing the lower half peripheral wall of the processing chamber case 26, that is, the lower case 26a so as to be openable and closable around the fulcrum P, in a variety in which a large number of branch stems occur. The lower case 26a can be used with the lower case 26a closed, and the lower case 26a can be used with the lower case 26a open for a variety that has less branching and is easy to remove. In addition, before and after the branch pruning processing device 27, remove. Branch shoot detection sensors 31 and 32 are provided, and the branch stems from the threshing device and the grain tank GT are removed, for example. Branch branch detection sensor-31
32 is provided, and the stripping between the sensors 31 and 32 before and after this is performed. The lower case 6a may be automatically opened / closed by measuring the value of the branch vein. In the figure, M
Indicates a lower case opening / closing motor.
