[Technical field to which the invention belongs]

 The present invention relates to an arrangement of a dust outlet processing cylinder for processing straw waste and the like that could not be processed by a handling cylinder of a threshing apparatus.

[0002]

[Prior art]

 Conventionally, in a threshing apparatus such as a combine machine, a technique in which a second processing cylinder is arranged in parallel at the rear end of a handling cylinder is known, and it is possible to handle a branch attached to a branch, which cannot be completely processed by the handling cylinder. It was sent from the rear end to the second processing cylinder where it was processed, reducing unprocessed materials and improving processing efficiency.

[0003]

[Problems to be solved by the invention]

 However, since the second processing cylinder was continuously arranged at the rear end of the handling cylinder, the length of the sorting device also had to be increased, and the machine became longer and longer in the front-rear direction. In addition, since the flow of the processed material is in a direction perpendicular to the rotation of the handling cylinder, the material is likely to be clogged at the boundary between the handling cylinder and the processing cylinder, and is likely to be clogged. I was doing it.

[0004]

[Means for Solving the Problems]

 In order to solve such a problem, the present invention provides a threshing device in which a processing cylinder is arranged in parallel with a handling cylinder, and a rear end of the handling cylinder and a front end of the processing cylinder are arranged in an overlapping manner in a side view. The start of the dust outlet that sends unprocessed material to the processing cylinder is located ahead of the front end of the movable chaff.

A straw chain 16 is provided at the rear end of the feed chain 7, and a straw cutter device 17 is provided below the rear portion of the straw chain 16 to cut the straw and discharge it to the field. I am trying to do it.

On the side of the threshing device B, a Glen tank 12 for storing the refined granules after sorting is provided, and in front of the Glen tank 12, an operator cab 19 is provided. At the rear, a vertical auger 18a of the discharge auger 18 is erected, and the Glen tank 12 is rotatable to the side around the vertical auger 18a. A discharge conveyor 22 is disposed at the bottom of the Glen tank 12 in the front-rear direction, and power is transmitted from the discharge conveyor 22 to the discharge auger 18 to allow the power to travel from the tip to a truck or the like. The paddy in the tank 12 can be discharged.

In the threshing apparatus B, as shown in FIGS. 3, 4, and 5, a handling cylinder 20 is laid horizontally in the front-rear direction, and handling blades 20a are implanted around the handling cylinder 20. The cutting blades 26, 27,... Protrude toward the center of the handle cylinder toward the feed chain 7 side and the back side inside the upper cover 30 of the handle cylinder 20, respectively, and cut the long culm entangled with the handle blade 20a. The crimping net 31 is provided around the lower part of the handling cylinder 20 so that only paddy and small straw chips fall.

A dust port processing cylinder 21 is laid in parallel with the handling cylinder 20 on the side of the Glen tank 12 behind the handling cylinder 20, and a partition plate 33 at the rear portion of the handling cylinder 20 and the front end of the dust port processing cylinder 21. A dust outlet 33a is opened at the bottom, so that unprocessed materials such as spike sticking particles which cannot be processed by the handling cylinder 20 are sent to the dust outlet processing cylinder 21. A crimping net 32 is provided around the lower part of the dust outlet processing cylinder 21 so that only the paddy, small straw chips, and the like fall. The mesh of the crimping net 32a of the crimping net 32 is the mesh of the crimping net 32b of the rear. By making it smaller, the granules leak on the front side, and the second thing leaks on the rear, making it easier to select the first thing and the second thing, respectively. Are sucked by the dust exhaust fan 39 and discharged outside the machine.

A sorting device C is provided below the handling cylinder 20 and the dust outlet processing cylinder 21, and the sorting device C is separated from the first one by specific gravity sorting by the rocking sorting device 15 and wind sorting by the Karamin 35. The swing sorting device 15 is provided with a pivot shaft 36 at a lower front portion and pivotally supports the rear portion with a crankshaft 37. The swing sorting device 15 swings by rotating the crankshaft 37.

A Glen Sheave 44 is provided below the hook 42.

The positional relationship between the movable chuff 42 and the dust port processing cylinder 21 is such that the starting end of the communication port 33 a to the dust port processing cylinder 21 is disposed forward of the front end of the movable chuff 42 and is provided with a sorting device. The front is used effectively to improve the sorting ability. The fins 42a of the movable chaff 42 are provided with imaginary lines connecting the upper ends thereof in a V-shape, as shown in FIG. Are arranged a distance L ahead of the boundary 32 'between the front crimping net 32a and the rear crimping net 32b of the crimping net 32, and the fins 42a, 42a,. The distance between each is gradually increased from the front to the rear, so that the first and second items are easily selected to prevent culm cutting and the like from entering the first conveyor.

Also, standing pieces 38, 38,... Project obliquely rearward on fins 42a at appropriate positions at the rear part of the movable chaff 42 so as to spread the processed material evenly. A sieve line 43 is provided at the rear end of the chaff 42. The sieve line 43 projects a number of rods rearward on a support shaft 43a placed on the movable chaff 42 in the left-right direction, and protrudes an arm 43b forward on the side of the support shaft 43a, and pivots the arm 43b to the body. The sieve wire 43 is also configured to swing by swinging of the swing sorting device 15 while supporting it.

As shown in FIG. 6, guide plates 45 and 4 are provided at the lower part of the drifting plate 40 so as to guide a part of the sorting wind from Karino 35 between the chaffs 41 and 42 and the grain sieve 44. 6, and guide plates 47 and 48 are also provided so that openings E and F are provided at the top and the rear around Karino, so that the sorting wind is sent from two directions to increase the sorting efficiency. Make up.

[0014] The fine granules sorted by the sorting device C in this way fall on the flocking plate 50 of the first conveyor 10 and are arranged on the side of the threshing device B via the frying conveyor 11. The second product is stored in the Glen Tank 12, drops from the falling grain plate 51, is returned from the second conveyor 13 through the second reduction conveyor 14 to the front of the oscillating sorting device 15, and is sorted again. Etc. are discharged from the rear.

[Effect of the invention]

 With the configuration described above, the present invention has the following effects. First, since the starting end of the dust outlet is located ahead of the front end of the movable chaff, unprocessed materials such as spike sticking particles enter the dust outlet processing cylinder through the dust outlet and are processed there. As a result, sorting efficiency increased, unprocessed materials could be reduced, high-speed work was made possible, and the work adaptation range was widened. Secondly, since the unprocessed material from the cylinder is processed through the dust outlet, the power consumed for the cylinder can be reduced and the flow rate can be increased.
