DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a threshing apparatus.

[0002]

2. Description of the Related Art In a conventional threshing apparatus, as disclosed in Japanese Patent Application Laid-Open No. Hei 6-53671, it is necessary to replace a grain sieve for rocking sorting of a rocking sorter with a different sieve having a different mesh size. Had to take out the swing sorting case from the rear of the threshing device.

[0003]

According to the above conventional construction, the swinging and sorting case must be taken out from the rear of the threshing device and the Glen Sheave must be replaced. In the case of a large-sized threshing device mounted on a throw-in type ordinary combine, the swing sorting case also became large and heavy, requiring a great deal of labor.

[0004] It is an object of the present invention to improve the workability of the swing sorter case even if the swing sorter case is large and heavy, by making it possible to easily replace the Glen sheave.

[0005]

[Means for Solving the Problems]

[Structure] The feature of the invention according to claim 1 is that, in the swing sorting apparatus, the first sheave for sorting the first object of the swing sorting apparatus is passed through a first opening formed in a first side wall of the swing sorting case. To be able to be inserted and removed freely from the side outside
A lid member that is detachably fixed to the first side wall by closing the opening in the mounted state is attached to the Glen Sheave, and the Glen Sheave is attached to the threshing device side plate facing the first side wall of the swing sorting case. Is formed as a second opening which can be taken in and out integrally with the lid member.

A feature of the invention according to claim 2 is that, in the invention according to claim 1, a guide rail for guiding insertion and extraction of the Glen Sheave is provided from a first side wall to a second side wall of the swing sorting case. The engaging projection and the engaging hole which are detachable from each other are distributed to an end opposite to the lid member and a second side wall of the swing sorting case corresponding to the end. It is located.

According to a third aspect of the present invention, in the invention according to the second aspect, the swing sorting case has a second structure.
A deposit discharge port is formed in a portion of the side wall near the end of the guide rail.

According to the first aspect of the present invention, when the grain sheave is replaced with a grain sieve having a different size, first, the grain sheave is opened with the second opening formed in the threshing apparatus side plate opened. The lid attached to the thruster is detached from the first side wall of the swing sorting case and pulled out laterally outward, and the Glen Sheave is taken out integrally with the lid to the lateral outer side of the threshing apparatus side plate. After that, the sieves having different sizes of meshes each having a lid attached thereto are inserted into the swing sorting case through the second opening and the first opening of the swing sorting case, and are mounted on the first side wall of the swing sorting case. Then, the lid member is fixed.

As described above, the replacement operation of the grain sheave may be performed simply by attaching and detaching the lid member to and from the first side wall of the swing sorting case, and inserting and removing the Glen sheave into and from the swing sorting case. Even if the swing sorting case is large,
Even if it is heavy, the replacement work of the Glen Sheave can be easily performed. Moreover, since the lid member is attached to the Glen Sheave, the work efficiency can be improved as compared with a case where the lid members are separated and separately mounted on a swing sorting case, for example.

According to the second aspect of the invention, in addition to the effect similar to that of the first aspect, the Glen Sheave is guided by the guide rail so that the Glen Sheave can be smoothly inserted and removed. Can be. Then, in a state where the Glen Sheave is mounted on the swing sorting case, the engagement distributed to the end of the Glen Sheave opposite to the lid member and the second side wall of the swing sorting case corresponding to this end. Since the projection and the engagement hole are engaged with each other, the Glen Sheave can be accurately positioned.

According to the third aspect of the present invention, in addition to the effect similar to that of the second aspect, the second side wall of the swing sorting case is provided near the end of the guide rail. Since the deposit outlet is formed, the deposit is less likely to be caught between the end of the Glen sheave and the second side wall of the swing sorting case.

[Effect] Therefore, according to the first aspect of the present invention, the workability of the replacement operation of the Glen sheave can be improved.

According to the second or third aspect, the Glen Sheave can be securely mounted at the set position, and the workability can be further improved.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1 and FIG. 2, a threshing unit 1 mounted on an all-culm-input type normal combine is provided with a threshing unit A for threshing the harvested culm fed by the feeder 13, and processing from the threshing unit A. And a sorting section B for sieving and wind sorting the objects.

The threshing unit A is composed of an axial-flow-type handling cylinder 2 having a spiral handling tooth 2A, a concave 3 stretched below the handling cylinder 2, and the like. By driving and rotating, the harvested culm is handled and processed to leak from the concave 3, and the waste straw is discharged from the rear of the handling chamber a.

The sorting section B comprises an oscillating sorting device 4 and a Karamin 5 for generating wind power for wind sorting. The oscillating sorting device 4 includes a first Glen pan 6 and a spare sheave 7.
A chaff sheave 8 connected to the preliminary sieve 7 for rough sorting of the processed material; a rear sieve 9 connected to the chaff sheave 8 for coarse sorting of the processed material; and a grain of the processed material leaked from the preliminary sheave 7 or the chaff sheave 8. The swing sorting case 11 is provided with a first grain sorting sieve 10 for grain sorting.

The grain as the first thing that has leaked from the above-mentioned grain sheave 10 is collected by a first thing collection part 12 provided below the grain sheave 10 and then disposed on the lateral side of the threshing apparatus 1. The second thing, such as the paddy with branch that has been stored in the drained Glen tank T and did not leak at the Glen Sheave 10 or the paddy with branch that has leaked from the Rear Sheave 9, is provided below the Rear Sheave 9. After being collected in the section 14, it is re-threshed in the second reduction device 15 and the rocking sorting device 4
Is returned to the beginning, and straw waste and rice hulls are discharged out of the machine by the sorting wind from Karamino5.
