[Problems to be solved by the invention] By the way, recently,
There is a demand for high-speed and compact combiners and good maintainability of various devices. In order to satisfy these demands, it is necessary to improve not only the reaper provided on the combine but also each part of the threshing machine mounted on the combine. In addition to the cylinders and the processing cylinders, it is necessary to improve a swing sorting device for sorting processed products processed by these handling cylinders.

On the side of the swing sorting apparatus, the sorting area is reduced as much as possible in order to make the whole machine compact, and the sorting process is performed in order to be able to cope with high-speed cutting and threshing work. There is a need to increase the capacity and further facilitate the removal of the swing sorting device from the outside, thereby improving the maintainability of the swing sorting device.

However, the above-described various improvements are mutually contradictory, that is, when the sorting area of the swing sorting apparatus is reduced to make it possible to cope with the downsizing of the entire body, When the sorting ability of the swing sorting apparatus is relatively reduced and it becomes impossible to cope with high-speed work, on the other hand, when the sorting processing capacity of the swing sorting apparatus is increased and it becomes possible to cope with high-speed work, the sorting area When it is not possible to make the entire body compact, and when the sorting area of the swing sorting device is made large, the whole swing sorting device becomes large and external take-out is not possible. It becomes difficult and its maintainability deteriorates.

Therefore, by reducing the size of the swing sorting apparatus in a two-stage configuration and reducing the size on a plane, the whole apparatus can be made compact and compact, but a large sorting area can be secured as a whole apparatus, and the sorting processing capacity can be secured. It is conceivable to make it possible to respond to high-speed operation by increasing the height.However, in such a case, since the vertical thickness of the entire swing sorting device is increased, repair and inspection work of the swing sorting device is performed. When moving the entire swing sorting apparatus in the lateral direction and taking it out from the outlet provided on the rear side of the body,
This makes it difficult to take it out, leaving problems in terms of maintainability.

That is, the size of the opening at the outlet is 2
It is determined by the height of the inclined wall for sorting the items and the lower edge height of the rear wall disposed behind the handling cylinder or the processing cylinder and extending below the handling room net or the processing room net. Therefore, the opening size cannot be made sufficiently large due to the improvement of the size. Therefore, when the swing sorting device is configured in a two-stage configuration and the overall thickness is increased, as described above, the size of the entire body is reduced and the speed is increased. Although it is possible to cope with work, it is difficult to take out the entire swing sorting apparatus from the outlet to the outside, and there is a problem in terms of maintainability.

[0008] The present invention has been made in view of the above-mentioned problems, and its purpose is to make it possible to make the entire body compact and to be able to cope with high-speed work.
An object of the present invention is to provide a rocking and sorting apparatus for a threshing machine which can also improve maintainability.

[0009]

Means for Solving the Problems In order to achieve the above object, a sorting apparatus which is supported in a machine body having a threshing unit and sorts cereals from a processed product threshed by the threshing unit, and a sorting apparatus for moving the sorting apparatus in a lateral direction In a threshing machine provided with an outlet to be moved and taken out from the inside of the machine, the sorting device comprises a first assembly supported by the machine and the first assembly supported movably by the first assembly. A second assembly disposed below the attachment, the thickness of which is larger than the opening size of the outlet; and the first and second assemblies have a thickness of It is characterized in that it is formed smaller than the opening size of the outlet so that it can be individually taken out / inserted from the outlet.

[0010]

The above-mentioned sorting apparatus has first and second assembled bodies, and the first and second assembled bodies are arranged in the upper and lower stages in the machine body. While the entire body can be made compact, a large sorting area can be secured as a whole of the sorting apparatus, and the sorting processing capacity can be increased to enable high-speed operation.

In addition, the first assembled body is movable toward the outlet with respect to the body, and the second assembled body is movably supported by the first assembled body. When taking out the whole to the outside of the fuselage in order to perform a repair inspection of the air conditioner, first, the second assembled body is moved to the outlet side with respect to the first assembled body, and the second assembled body is moved from the outlet to the outside. take out,
Thereafter, the first assembled body is moved to the outlet side and taken out from the outlet, so that the first and second assembled bodies, that is, the entire sorting device, can be easily taken out of the body. Therefore, the maintainability of the sorting device can be improved.

That is, the swing sorting apparatus is composed of the two first and second swing sorting assemblies 4A and 4B, so that the entire body can be made compact and high-speed work can be performed as described above. And the rocking sorting assembly 4A, 4B is disposed vertically in the body 1 to increase the height of the rocking sorting apparatus as a whole. By making each of the swing sorting assembling bodies 4A and 4B separately drawable from the outlet to the rear side of the machine, the outlet is not enlarged, that is, threshing with a handling cylinder or a processing cylinder. In order to sort out the second of the processed products, the inclined wall 2 extended to near the outlet

The entirety of 4B can be pulled out from the outlet 8 at the rear of the body 1 separately from the first swing sorting assembly 4A.

Next, the operation of the swing sorting device 4 configured as described above will be described. First, when the processed material that has been threshed by the handling cylinder 21 or the processing cylinder 22 is sorted by the swing sorting apparatus 4, the first and second swing sorting assemblies are clearly shown in FIG. 4A and 4B are set inside the body 1 in a state where they are superimposed on each other in the upper and lower stages, and the swing drive arm 47 connected via the bracket 46 is swingably driven, whereby the first swing is performed. While the first rolling wheel 45 provided on the dynamic sorting assembly 4A is in contact with the upper front side of the support guide 9, the first swing sorting assembly 4A is swung up and down and back and forth. As a result, the second swing selection assembly 4B supported in an overlapping manner on the upper side of the first swing selection assembly 4A is swung together in the up-down and front-rear directions. The processed material threshed by the handling cylinder 21 and the processing cylinder 22 by the bodies 4A and 4B It is to separate processing.

At this time, since the first and second swing sorting assemblies 4A and 4B are set up and down inside the body 1, the size of the swing sorting device 4 is reduced. The entire aircraft can be made compact, and
The swing sorting device 4 is provided with the two swing sorting assemblies 4.
Since the swing sorting device 4 is composed of A and 4B, a large sorting area can be secured as a whole of the swing sorting device 4, and the sorting processing capability can be increased to enable high-speed operation.

When taking out the whole of the swinging sorting device 4 to the outside of the body 1 in order to perform a repair inspection or the like, first, the left and right swinging and supporting device 4B supported by the second swing sorting assembly 4B is used. While rolling the set of second rolling wheels 55 along a pair of left and right guide rails 48 provided on the first swing selection assembly 4A, the entirety of the second swing selection assembly 4B is The swinging sorting assembly 4A is pulled out separately from the body 1
It is taken out from the outlet 8 provided on the rear side of the machine. And, in this way, the second swing sorting assembly 4
After taking out B to the outside of the fuselage 1, a pair of left and right first rolling wheels 45 supported by the first swing sorting assembly 4 </ b> A are moved along a pair of left and right support guides 9 provided on the fuselage 1. By pulling the first swing sorting assembly 4A out of the outlet 8 while rolling backward, the swing sorting assemblies 4A and 4B, that is, the entire swing sorting device 4, Can be easily taken out of the machine body, and the maintainability of the swing sorting device 4 can be improved.

That is, since the swing sorting device 4 is composed of the first and second swing sorting assemblies 4A and 4B, as described above, the whole body can be made compact and high-speed work can be performed. In addition, when each of the swing sorting assembling bodies 4A and 4B is set up and down in the body 1 in an up-and-down step, the total thickness A is equal to the opening dimension B of the outlet 8. Higher than the above, each said swing sorting assembly 4
The maximum thicknesses a1 and a2 of A and 4B are the same as the opening dimension B.
Therefore, each of these assembled bodies 4A and 4B can be separately pulled out from the outlet 8 to the rear side of the fuselage 1, so that it is not necessary to make the outlet 8 particularly large. In other words, in other words, the opening dimension B of the outlet 8 can be smaller than the thickness A when the swing sorting assemblies 4A and 4B are set up and down, and
Each of the maximum thicknesses a1, a of these swing sorting assemblies 4A, 4B
The swing sorting assemblies 4A and 4B can be individually pulled out of the machine body while the sorting area becomes larger than 2 and the sorting area can be gained. Therefore, the take-out port 8 is particularly large, and the second take-out conveyor 7 is used to sort out the second product from the thresh-processed products processed by the handling cylinder 21 and the processing cylinder 31. Each of the swing sorting assemblies can be used without limiting the size of the sloped wall 71 extended to the vicinity of the exit 8 and without impairing the ability of the sloped wall 71 to sort the second item. 4A, 4B to the outlet 8
Can be easily taken out of the machine body to perform the repair inspection work of the entire swing sorting apparatus 4, and the maintainability thereof can be improved. In addition, the swing sorting device 4 is divided into the swing sorting assemblies 4A and 4B, and the individual weights of the swing sorting assemblies 4A and 4B unite the swing sorting device 4. Since it is reduced as compared with the case, the operability when taking out each swing sorting assembly 4A, 4B from the outlet 8 to the outside can be improved.

In the above embodiment, the first and second swing sorting assemblies 4A and 4B are set up and down in the body 1 so that the first swing sorting assembly 4A is assembled with the first swing sorting assembly 4A. The swing drive arm 47 swings up and down and back and forth. At this time, the second swing sorting assembly 4B supported on the upper side of the first swing sorting assembly 4A is caused to follow and swing together. However, in addition to the above, the swing-selecting assemblies 4A and 4B are provided on the body 1 side and individually supported by a pair of swing-drive arms (not shown), respectively. The sorting assembly 4A may be gently rocked with a large vibration amplitude, and the second swing selection assembly 4B may be rocked with a small vibration amplitude in small increments. The processing object dropped and supplied from the cylinder 21 or the processing cylinder 31 is roughly sorted by the first swing sorting assembly 4A. And said second oscillating sorting assembly body 4B
The above-mentioned process can be carefully selected.

Further, each of the swing sorting assemblies 4A, 4B
Can be rocked in opposite directions at the same speed. In this case, the rocking reaction forces of the rocking sorting assemblies 4A and 4B are cancelled, and the rocking sorting is performed. Vibration during swinging of the assembled bodies 4A and 4B can be reduced.

[0027]

As described above, according to the present invention, the thickness of the sorting device having the upper and lower two-stage configuration by the first and second assemblies is larger than the opening size of the outlet. Therefore, it is possible to respond to high-speed operation by increasing the sorting processing capacity without increasing the size of the outlet at the rear part of the fuselage, and the thickness of the first and second assembled bodies is limited by the opening dimension of the outlet. Since it is formed smaller and can be individually taken out / inserted from the outlet, it is possible to take out the entire sorting device to the outside of the fuselage and to easily perform repair and inspection work, thereby improving maintainability. In addition, since the sorting device has a two-stage configuration with the first and second assembled bodies,
The entire sorting machine can be made compact by making the entire sorting apparatus compact.
