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 which is being dropped and supplied to a bait collecting unit with a sorting wind from Kara no Tamo 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 treated material is biased to one side in the left-right direction of the thresher due to the rotational direction of the handling cylinder. In the state, that is, in the state where the inner part of the body is biased toward the back as seen from the feed chain holding the plant of the grain culm, that is, it tends to leak to the sorting device in a state along the front-rear direction,
This leaked processed material was likely to be accumulated at a specific location of the sorting device. For this reason, there is a drawback in that even if the Karafu breeze is blown to the processed products accumulated in a specific place, the selection between the No. 1 product and the No. 2 product is not sufficient, and the selection performance remains low.

The present invention has been made in view of the above circumstances, and the structure of the sorting unit of the threshing apparatus which can favorably perform the sorting by the Karafu wind even when the processed products are concentrated in a specific portion of the sorting unit. For the purpose of providing.

[0005]

In order to achieve the above object, the structure of the sorting unit of the threshing apparatus according to the present invention is of the structure described in the beginning, in which the processed product is dropped and supplied to the first product collecting unit. A deflecting device is provided between the road and the Karato so that the sorting wind from the Karato toward the rear of the machine is biased in the lateral direction of the machine to be guided. Further, it may be configured such that the degree of guiding the sorting wind in the deflecting device in the lateral direction of the body can be changed and adjusted, and between the Kara and the deflecting unit, the air from the Kara can to the rear of the body. A configuration may be provided in which a branching device that branches up and down the air path of the sorting wind toward the upper and lower sides is provided. The operation and effect of this characteristic configuration are as follows.

[0006]

In other words, since the Karato wind to the processed material dropped and supplied to the No. 1 object recovery section is in a state of being blown by the deflecting device in the lateral direction of the machine body, the processed material on the Glen sieve or the Glen sieve For the processed product that leaks from, because it is blown obliquely to the processed product in the state of overlapping in the front-back direction, it will be sufficient compared to the conventional that is simply blown in the front-back direction, Sorting is done more reliably.

[0007]

Therefore, since the selection by the Karafu style is made more reliable, it is possible to prevent undesired mixture of branch stems, straw debris, etc. in the No. 1 collecting section and to improve the selection performance. I was able to do it.

[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. 6, the swing sorting device 6 and the karako 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 front and rear in a continuous state across both sides of a sheave case 9 which can be driven to swing, and a chaff sheave 12 is provided on the upper end 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 of the processed material to the first material collecting section 14 and the Kara-mino 7, the sorting wind from the Kara-moh 7 toward the rear of the machine is biased in the left-right direction of the machine. A deflecting device 15 is provided for guiding. That is, as shown in FIG. 2, the deflecting device 15 is provided with a large number of louvers a ... Which deflect the rearward selection wind from the right side to the left side over the air blow opening of the Karako 7 across the airframe. Support frame 1
6 is supported and provided. It should be noted that the louvers a ... Can change the deflection direction freely, that is, can change and adjust the degree of the angle for guiding the sorting wind in the deflecting device 15 by biasing it in the lateral direction of the machine body. The operating mechanism is linked to. Therefore, even when the position where the leakage of the processed material from the receiving net 4 to the sorting section 5 is biased to the right of the machine, air is blown from the right to the left so that the sorting wind acts on the entire processed material. Will be done.

As shown in FIG. 1, a branching device 17 is provided in the sorting wind passage between the deflecting device 15 and the Kara-no-Mizu 7 so as to vertically split the sorting wind passage. This branching device 17
Has a structure in which it is possible to change the direction of branching and blowing of air up and down. Specifically, as shown in FIG. 3, a pair of upper and lower airflow guide plates pivotally attached vertically with a hinge structure at the front end. 18 and 19 are provided, and the other ends of the pair of upper and lower link arms 20 and 21 pivotally attached at one end to the plates 18 and 19 are pivotally attached to the top member 23 of the screw feed mechanism 22 to drive the electric motor 24. With this, by moving the top member 23 back and forth, it is possible to change the direction of branching and blowing. The driving operation of the electric motor 24 is arbitrarily performed by a driver by operating a switch or a lever in a driving section or the like. Due to the upper and lower branches of the sorting air, the blowing air to the chaff sheave 12 and the like and the blowing air to the processed matter leaked from the Glensieeve 11 are respectively concentrated, so that the sorting air is effectively acted.

The deflecting device may be one in which the air blowing direction is fixed to a predetermined direction, or the air blowing direction is set such that the right louver is set to the right and the left louver is set to the right from the middle of the lateral direction of the machine. You may turn it to the left.

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 configurations of the accompanying drawings by the entry.
