Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention comprises a handling chamber for accommodating a handling barrel and a dust-exhausting chamber provided with a suction dust-exhausting fan to thresh grain culms and select wind. It relates to a threshing machine.

(B) Conventional technology As a conventional threshing machine configured as described above, for example, as is known from Japanese Utility Model Publication No. 48-28685, there is a space between the handling chamber and the suction dust collecting fan. The unprocessed material from the handling chamber is processed by interposing a processing chamber containing a relatively large-diameter processing cylinder having processing teeth implanted in its surface.

Therefore, a wide space is required between the handling room and the suction dust collecting fan, which is an obstacle to the downsizing of the entire length and height of the machine.

(C) Problems to be Solved by the Invention As described above, in the conventional structure, a wide space is required between the handling chamber and the suction dust collecting fan, and the entire length and height of the machine are inevitably large. The present invention has been invented in an attempt to further improve the performance of processing unprocessed material from the handling room while eliminating the obstacles due to this size reduction. It is a thing.

(D) Means for Solving the Problems Therefore, in order to achieve the above object, the present invention provides:
Between the handling chamber that houses the handling cylinder and the suction / dust fan installed in the dust removal chamber, a processing cylinder with a spiral wound around the circumference is installed inside the processing chamber and opened on the straw side of the handling chamber. The untreated material from the dust outlet is transferred to the grain culm supply side by a transfer processing device, and the processing chamber that constitutes the transfer processing device is located at a position closer to the extremely cold supply side than the straw side. And the grain culm supply side end is opened to communicate with the dust chamber, and the processing cylinder is opened from the treatment chamber through the opening formed by opening the grain culm supply side end. Extend to the supply side, and fix several projections protruding from the outer peripheral part of the spiraler corresponding to the dust sending port, and hook unprocessed objects from the dust sending port with the projections to positively Incorporate the captured data forcibly by a spiral to process it. Than it is.

(E) Action With this configuration, the grain culms that are fed laterally from the grain culm supply side to the straw side in the handling chamber are de-culered by the rotation of the handling barrel, and the de-culled grain culms are discharged to the straw side. From the machine, unprocessed materials such as spikes and grains with branch stems that are not culled in the handling room are sent from the dust outlet on the straw side into the conveyor processing device.
It is processed by being spoiled while being conveyed toward the grain culm supply side by a spiraler wrapped around the peripheral surface of this conveyance processing device.

Then, dust such as grains and straw dust that leaks from the handling chamber and those that have been processed by this transfer processing device are selected by the wind generated by the rotation of the suction / dust fan, and the dust is sucked and discharged. The dust is sucked and discharged outside the machine, and the grains are taken out separately.

In that case, the dust is delivered from this dust-sending port by several protrusions fixedly provided on the outer peripheral portion of the spiral wound around the peripheral surface of the processing cylinder constituting the above-mentioned transfer processing device. Is trapped, actively taken in and dispersed, and is then forcibly conveyed from the straw side to the grain culm supply side by the spiraler to treat the cuttings and the grains with branch branches, and this treatment is performed. The soup is delivered from the opening at the end of the grain culm supply side and discharged to the dust chamber.

(F) Examples The present invention will be described in detail below with reference to the examples.

A processing cylinder (10) having a spiral (5) wound around its peripheral surface is installed inside a processing chamber (9) extending up to the location so as to be rotatable in the direction of the arrow (b). Straw side is dust port (6)
The side part that communicates with the handling room (1) and is laid laterally up to the part close to the grain culm supply side is opened to form the opening (11),
The opening (11) leads to the interior of the dust chamber (4).

Further, the processing cylinder (10) extends from the inside of the processing chamber (9) to the grain culm supply side through the opening (11).

Around the lower side of the processing chamber (9) is formed an arc-shaped receiving net (12), and a protrusion (13) protruding from the outer peripheral portion of the spiral (5) corresponding to the dust inlet (6) is formed. ) Are fixed at equal intervals.

(14) is a guide plate that is obliquely installed so that the dust chamber (4) faces from the bottom of the dust inlet (6), and (15) is an opening (11).
And a grain culm supply side, a falling plate (1) for letting out what comes out of this opening (11) from the inner part of the dust chamber (4).
6) is a downflow plate that guides leaked material from the net (12) between the guide plate (14) and the downflow plate (15) toward the arm of the handling chamber (1), and (17) is A partition wall that closes the space between the guide plate (14) and the falling plate (16), and a partition wall (18) that closes the spaces between the falling plates (16) and (15).

(19) is a partition plate which is erected to narrow the lower side of the opening (11), and the portion of the spiral (5) which rotates the position of this partition plate (19) is cut out to form a partition plate ( A notch (p) into which 19) is inserted is provided.

Reference numeral (20) is a sorting chamber provided below the handling chamber (1), and the sorting air passage (22) is formed by the cooperation of the pressure air fan (21) and the suction dust collecting fan (3). An oscillating sorting plate (23) whose end is made of a mesh is mounted between the sorting air passage (22) and the handling room (1). (24) is a flow plate that guides the rocking sorting plate (23), and (25) is the flow plate (1).
6) is a rubber plate that connects this grain plate (24) with (2)
6) corresponds to the width of the dust inlet (6), and the shed plate (24)
The sieve line protruding from the upper end of the inside of the dust chamber (4), (27) is the No. 1 trough provided at the bottom of the sorting air passage (22), and (28) is at the bottom of the dust chamber (4). The second trough (29) provided is a thrower that returns the items in the second trough (28) to the handling room (1).

As a result, the grain culm laterally fed from the grain culm supply side to the straw side in the handling room (1) is threshed by the handling barrel (2) rotating in the (a) direction, and leaks through the crimp net (8). The fallen ones fall onto the rocking sorting plate (23), and the non-leaking spikes and grain with branching stems enter the processing chamber (9) constituting the transfer processing device (a) from the dust inlet (6). This is sent out, and by the rotation of the processing cylinder (10) in the (b) direction, several projections (13) fixed to the outer peripheral portion of the spiral (5) are caught and positively taken in. After being dispersed and dispersed, it is forcibly conveyed to the grain culm supply side by the spiral (5) and treated so as to be caught between them.

If the starting end of the net (12) leaks from this processing action, the guide plate (14) flows down the sieve (26) and sifts it, and leaks from other parts of the net (12). The dropped ones flow down from the falling plate (16), through the rubber plate (25), over the grain plate (24), and fall onto the rocking sorting plate (23), leaking the net (12). Those that do not fall down are temporarily blocked by the partition plate (19) and resistance is applied to the spiral (5).
Thus, the dust is discharged from the opening (5) and discharged from the falling plate (15) into the dust chamber (4).

Therefore, what has fallen on the rocking sorting plate (23) is wind-selected by the rocking action by rocking and the wind that blows through the sorting wind passage (22), and is screened by the sieve line (26) and falls. The ones and those discharged from the flow-down plate (15) on the supply side are sorted by the wind sucked by the suction / dust fan (3), and the No. 1 grain goes out of the No. 1 trough (27). The second object is taken out and collected in the second object gutter (28) and returned to the handling room (1) by the thrower (29), and dust such as straw waste is taken out of the machine from the suction / dust fan (3). It is discharged to.
