Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention According to the present invention, a processed material leaking from a receiving net below a handling cylinder is gravity-sorted by a Glen pan, and also leak-sorted by a Glen sieve, and 1
The present invention relates to a sorting unit structure of a threshing device configured to sort a processed product that is being dropped and supplied to a bait collecting unit with a sorting wind from Karatsu from the front.

[0002]

2. Description of the Related Art Conventionally, as a sorting section structure of this type of threshing apparatus, for example, a structure disclosed in Japanese Patent Laid-Open No. 2-276509 is well known.

[0003]

By the way, in the above-mentioned conventional structure, the sorting wind from the Karato is blown to a certain position in the processed product transfer direction in the swing sorting device including the Glen pan and the Glen sieve. I was doing so
For example, it has not been possible to change the direction of the sorting air to a location where good sorting can be performed depending on whether the amount of processed material is small or large.

The present invention has been made in view of the above circumstances, and provides a selection unit structure of a threshing device capable of blowing selection air in a direction suitable for selection in accordance with conditions such as the amount of processed material. To aim.

[0005]

In order to achieve the above-mentioned object, the structure of the sorting section of the threshing apparatus according to the present invention is of the structure described above, in which the processed product is dropped and supplied to the first product collecting unit. A branching device for branching and guiding the wind path of the sorting wind from the Kara Mino to the rear of the aircraft up and down is provided between the road and the Kara Minoh, and the direction of the upper and lower branch guided air paths is up and down. The characteristic configuration is that it can be changed and adjusted in the direction. The actions and effects of this characteristic configuration are as follows.

[0006]

In other words, since the sorting air that has been branched up and down by the branching device can be adjusted by changing the direction of the air passages up and down, for example, when the amount of processed material is small, The sorting wind is blown toward the upper part of the processed product transfer direction and the vicinity of the first product collection part, so that most of the grains of the processed product are the second product collection part behind the selection part. On the other hand, when there is a large amount of processed products, on the other hand, for the processed products in the rocking sorting device, the sorting wind in a state in which the upper and lower two layers flow toward the lower hand in the processed product transfer direction is blown. In this way, the selected air is sufficiently blown to the processed material that leaks on or through the Glen sieve.

[0007]

Therefore, by changing and adjusting the blowing direction of the branching device, it is possible to appropriately blow the air according to the condition of the processed material, and it is possible to perform the good selection.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a threshing device 1 mounted on a combine. This threshing device 1 is provided with a handling chamber 2 in the upper part, and a handling barrel 3 is installed in the handling chamber 2 in a state of being rotationally driven around a longitudinal axis. Below the handling cylinder 3, a receiving net 4 for leaking the treated material is disposed, and
Below the receiving net 4, a sorting unit 5 for sorting the processed material leaked from the receiving net 4 is provided. This sorting unit 5 is shown in FIG.
As shown in FIG. 2, the swing sorting device 6 and the karakin 7 for sending the sorting wind
The collecting section 8 is provided below the sorting section 5.

The swing selecting device 6 is provided with a Glen pan 10 and a Glen sheave 11 in a front and rear direction in a continuous state over both sides of a sheave case 9 which can be driven to swing, and a chaff sheave 12 is provided on the upper portion of the Glen sheave 11, In addition, a straw rack 13 is provided behind the chaff sheave 12. The processed material leaking from the receiving net 4 is gravity-sorted by the Glen pan 10, roughly sorted by the chaff sheave 12, and leak-sorted by the Glen sieve 11, and is dropped and supplied to the No. 1 material collecting section 14 below the Glen sieve 11. To do.

Then, between the drop supply path to the No. 1 material collecting section 14 and the Kara Mino 7, the air path of the sorting wind from the Kara Mino 7 toward the rear of the machine is branched and guided up and down. A branching device 15 is provided. As shown in FIG. 2, this branching device 15 is provided with a pair of upper and lower blower guide plates 16 and 17 pivotally mounted in a swingable manner up and down with a hinge structure at the front end. The other ends of the pair of upper and lower link arms 18, 19 pivotally attached to each other are attached to a screw feeding mechanism 20.
It is possible to change the direction of branching and blowing by moving the top / bottom member 21 by moving the top / bottom member 21 by pivoting to the top member 21 and driving the electric motor 22. Therefore, this branching device 15
By adjusting the opening / closing angle of the hinge structure at the front ends of the plates 16 and 17 of each other by driving the electric motor 22,
It is possible to change the direction of branching up and down. The driving operation of the electric motor 22 is arbitrarily performed by a driver in a driving section or the like by operating a switch or a lever.

Further, as shown in FIGS. 1 and 3, in the lower position of the Glen sieve 11, the front and rear branching unit 23 which sorts the processed matter leaked from the Glen sheave 11 back and forth and drops and feeds it to the No. 1 thing collecting section 14. Is provided. The front-rear branching device 23 has a side-view mountain-shaped guide plate 23a, so that the front-rear spacing of the fall supply paths distributed forward and backward can be changed and adjusted.
23a is configured to be capable of swinging and opening / closing operations up and down around the apex.

The branching device 15 adjusts the airflow direction of the vertically separated sorting air, so that, for example, when the amount of processed material is small, the swinging sorting device 6 moves the processed material in the processed material transfer direction. The selection wind is blown toward the upper hand and the vicinity of the first product recovery unit 14 so that most of the grains of the processed products do not enter the second product recovery unit behind the selection unit. On the other hand, when there is a large amount of processed material, the swing sorting device 6
For the treated products in the above, the sorting air in a state in which the upper and lower layers flow in the lower direction in the treated product transfer direction is blown to sufficiently sort the treated products leaking on or from the Glensieves 11. The air is blown, so that the air can be appropriately blown according to the condition of the processed material.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
