Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a threshing device in which the threshing dust generated during threshing in the handling cylinder is passed to the processing cylinder behind this to thresh the grains in the dust.

[0002]

[Prior art]

 A cutting blade is provided in the front half of the handling body in the handling room to cut long culms such as culms that are drawn into the handling room and withdrawals from the feed chain.

[0003]

[Problems to be solved by the device]

 However, in a structure having a processing cylinder, a cutting blade is not normally installed in the width of the inlet between the handling cylinder and the processing cylinder. Is not transferred smoothly to the processing cylinder, and noise is not generated during processing work on the processing cylinder, and long culm is wound on the processing cylinder and the processing cylinder. However, there was a problem that the required power was increased.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is provided with a handling cylinder for threshing cut culms and a processing cylinder, a dust delivery valve for guiding rearward the threshing dust generated during threshing by the handling barrel, and the dust passing to the processing cylinder. In the structure provided with a dust feed reverse reed valve that guides the dust, a cutting blade for cutting dust is provided on the feed chain side plate near the dust confluence part of the dust feed valve and the reverse reed valve. Therefore, even when long straws are pulled out from the feed chain and handed over to the processing cylinder from the handling cylinder to the processing cylinder, they are shredded by the cutting blade and smoothly. It is possible to prevent static noise from being generated by long straws during transfer work to the processing cylinder or during processing work on the processing cylinder, and to perform static work to promote the shedding effect. In order to prevent long straws from wrapping around the handling cylinder and the processing cylinder, a jam or accident may occur. The main power is reduced and yet one which with good dispersibility Waso during exhaust of the exhausted dust of the third port.

The wind direction plate (42) is installed in the fan case (41) with the rear end tilted to the right from the front end, and the dust falling from the processing cylinder (7) (especially when the fan (35) is suctioned on the right side) The dust that falls immediately after the torso (7) does not disperse) and the straw from the cutter (36) is diffused and discharged to the right side of the airframe by the exhaust air from the fan (35), and the fan ( Exhaust air from 35) directly flows to the cutter (36) It is configured so as to reduce the inconvenience such as hitting a cover or the like and being wound up on the 4th gutter (38) to accumulate dust.

The wind direction plate (42a) may be installed below the air exhaust port (41a) of the fan cane (41) as shown by the phantom line in FIG.

On the other hand, in the handling chamber (20), a dust delivery valve (43) for guiding rearwardly discharged dust and shattered substances such as straw dust generated at the time of threshing is opened at an opening / closing angle via a spindle (44). A reed angle can be adjusted on the threshing upper plate (45) freely, and a reverse reed valve (46) having a reverse lead angle to the dust delivery valve (43) is provided at the rear end position of the handling cylinder (6). It is provided in (45), and when the dust or the like which is moved by the guide of the dust transfer valve (43) reaches the rear end of the handling cylinder (6), the reverse reed valve (46) moves in the direction of the processing cylinder port (24). It is configured to guide and promote good transfer to the processing cylinder (7).

Further, a first cutting blade (48) is provided on the side opposite to the feed chain of the attachment frame (47) to which the crimp net (22) is attached, so as to prevent cutting of long straws during threshing and prevention of rotation of straws. In the vicinity of the dust merging portion (A) between the dust sending valve (43) and the reverse reed valve (46) during the opening operation, the upper side plate (45) is fed to the feed chain side through the receiving plate (49). Two cutting blades (50) are provided so that long straws and the like that are located after the cutting blades (48) and that are pulled out to the feed chain (5) are cut by the cutting blades (50). It prevents the noise from being brought into the processing cylinder chamber (23) and wraps around the processing cylinder (7), and also disperses the dust falling from the dust discharge port (37). It is configured to be good.

Furthermore, a movement restricting plate (51) is provided at a lower position facing the reverse reed valve (36) in the handling chamber (20), and the movement restricting plate (51) is directly provided to the dust outlet (28) behind this. It is configured so as to regulate the movement of such dust and the like to promote the transfer of the reverse reed valve (46) toward the processing body port (24).

By the way, a warning lamp (52) and a protection pipe (53) for protecting the upper portion of the lamp (52) are provided on the front surface of the discharge port (19a) of the discharge conveyor (19), and the machine body is made of a sheet or the like. The pipe (53) prevents the lamp (52) from being damaged during coating. As shown by the phantom line in FIG. 2, a chain auxiliary cover (55) is additionally extended at the front end of the feed chain cover (54) that covers the left side of the feed chain (5), and the main body side chain cover (54) is extended. The auxiliary cover (55) is integrally connected to the rotary bearing member that supports the front end side of the feed chain (5).

The present embodiment is configured as described above, and the feed chain (5) holds the root side of the grain while the tip end of the grain is moving in the handling chamber (20) while the handling tooth of the handling barrel (6) is being moved. Grains dehulled by (6a) fall through the crimp net (22) to the lower rocking sorter disc (26), and dust such as dust and straw dust that does not leak through the crimp net (22). The dust particles and the dust particles of the dust are sent to the rear by the guide of the dust feed valve (43), and the dust merging portion (A) of the dust feed valve (43) and the reverse reed valve (46). When dust and the like is sent to the processing chamber, it is sent to the processing chamber (23) by the guide of the reverse reed valve (46) toward the processing chamber opening (24), and while moving in the chamber (23). Separation of stab grain and shattering of grain with branching are performed to reduce grain loss.

Thus, during the threshing operation in the handling room (20), the long straw and the like pulled out from the feed chain (5) are cut by the first cutting blade (48) and the first cutting blade (48). ) Below a certain length, a long straw or the like pulled out from the feed chain (5) is cut by the second cutting blade (50) until it joins the reverse reed valve (46) (A). Dust that has been cut into short pieces can be smoothly and satisfactorily transferred to the processing cylinder (7), and even during processing work on the processing cylinder (7), static and static noise is not generated. Well done. Further, the dispersibility of the dust discharged from the dust outlet (37) can be further improved by the synergistic effect with the exhaust air diffusion action of the wind direction plate (42).
