Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting section structure of a threshing device mounted on a combine or the like, and more specifically, a Glen Pan for receiving a leaked substance which has leaked through a net in a handling room, and this Glen Pan. The front sorting unit equipped with the front and rear side of the grain sieve that sorts the leaked substances sorted by specific gravity to the first collection unit, and the non-leakage substances that have fallen from the dust inlet behind the handling chamber. The present invention relates to a sorting unit structure of a threshing device including a sorting unit for sorting.

[0002]

2. Description of the Related Art Conventionally, as a sorting section structure of this type of threshing apparatus, as disclosed in, for example, Japanese Patent Laid-Open No. 63-207319, a front sorting section and a rear sorting section are sorted by different drive systems. It is working. For details, regarding the leaked substances that have leaked through the receiving net, since the mixing ratio of contaminants such as straw chips is small, it is necessary to drive the front sorting section to repeat the reciprocating motion in the front-rear direction. The difference in specific gravity makes it easier for the grains to be separated into upper and lower parts, while the non-leakage substances discharged from the dust inlet in the rear of the handling room are foreign matter such as straw debris, etc. Since the mixing ratio of the above was large, the post-treatment section was driven to be swung up and down so that the processed product was shaken up and down so that the contaminants could be easily removed by the sorting wind from the Karako.

[0003]

However, in the above-mentioned conventional structure, since the Glen pan for selecting the specific gravity of the leaked material from the receiving net is fixedly installed in a fixed posture, it is fixedly installed. If the posture is almost horizontal, the wet pans may be sorted out, or when there is a large amount of leaked material, the pans may not adhere to the pans or may not move. There is a risk that it will slow down and reduce the specific gravity selection capability. Conversely, if the fixed position of the Glen Pan is tilted greatly with the rear part positioned slightly lower, leakage from the receiving net will occur. When a product with a high degree of dryness is selected or the amount of leaked material is small, it will be supplied to the Glensieve shortly after the specific gravity is sorted, and it is easy for straw dust to be mixed in the leaked material of the Glensieve. Become There is a possibility that sorting capacity becomes low. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sorting unit structure of a threshing device that can exhibit optimal sorting performance in accordance with the conditions of processed products.

[0004]

Means for Solving the Problems In order to achieve the above object, a sorting section structure of a threshing device according to the present invention includes a Glen pan for receiving a leaked substance which has leaked through a net in a handling room, and Pre-sorting section equipped with front and rear side of the grain sieve for sorting the leaked material sorted by gravity in the grain pan to the first collection section, and non-leakage dropping from the dust port behind the handling room A second drive unit for reciprocating the front selection unit substantially along the leaking selection surface of the Glensieve, and a second selection unit for eccentrically and vertically swinging the rear selection unit. It is characterized in that a drive mechanism is provided and the inclination degree of the Glen pan with respect to the leakage selection surface of the Glen sieve can be changed and adjusted. The operation and effect of this characteristic configuration are as follows.

[0005]

In other words, since the inclination of the Glen Sieve of the Glen Sieve with respect to the leakage selection surface can be freely changed, it is possible to select wet threshing-treated products or when there is a large amount of leakage-treated products. Is capable of performing specific gravity selection while suppressing the adherence of the processed product to the Glen pan or speeding up the transfer of the processed product by setting the degree of inclination of the Glen pan relative to the leakage lower surface of the Glen sieve to a relatively steep state. At the same time, when the dry threshed material is sorted or the amount of the leaked material is small, the specific gravity of the grain pan is selected by setting the inclination of the Glen Pan relative to the leak lower surface of the Glen Sieve to a relatively gentle inclination. The treated product can be supplied to the Glensieve in a state where the above is sufficiently performed.

[0006]

[Effects of the Invention] Therefore, by changing the inclination degree of the grain pan according to the conditions such as whether the threshed product is wet or dry, the amount of the processed product, or the difference in crops such as rice and wheat, Since the specific gravity sorting capacity can be optimized, the sorting performance can be improved.

Further, the grain sheave 17 is arranged such that its selecting surface is substantially horizontal. With this configuration, the leaked material that has leaked from the front portion of the receiving net 4 is directly received by the Glen pan 13. Glen Pan 1
The processed product received in 3 is fed to the Glen sieve 17 while being subjected to specific gravity selection by the reciprocating selection drive of the pre-selection unit 8 and the structure of the Glen pan 13 so as to separate the grains into the lower layer and the straw wastes into the upper layer. The processed product filtered by the Glensieve 17 is recovered by the first product recovery unit 12, and the processed product that cannot be filtered by the GlenSieve 17 is recovered by the second recovery unit 14 from the rear end of the GlenSieve 17. In the figure, reference numeral 11 denotes a Straw rack member which is provided on the upper surface of the rear portion of the Glen pan 13 side by side at a predetermined interval. As a result, contaminants such as straw scraps floating in the upper layer due to the specific gravity selection in the Glen pan 13 rides on the Straw rack member 11 ... It becomes easy to be damaged.

The rear sorting section 9 is provided with a pair of left and right rear frame plates 19 and 19 in the rear portion of the front sorting section 8 in a state of being overlapped in a side view, and two upper and lower stroll racks are provided over the rear frame plates 19 and 19. It is configured by providing 20 and 21. The upper straw rack 20 is disposed below the dust feed port 5 of the handling chamber 2, and swings and transfers the processed matter discharged from the dust feed port 5 rearward while filtering and sorting it, and discharges it from the rear end. . And
The filtered material filtered by the upper Straw rack 20 is discharged to the second material collecting unit 14, and the non-filtered material discharged from the rear end of the upper Straw rack 20 falls to the lower Straw rack 21. Then, while being filtered and sorted again by the lower straw rack 21, the lower stroll rack 21 is oscillated and transferred rearward. Then, the filtered material of the lower Straw rack 21 is also collected in the second material collecting section 14.

Next, the drive structure of the front sorting section 8 and the rear sorting section 9 will be described. As shown in FIG. 1, a pair of left and right idler rollers 22 and 23 are axially supported in front of and behind the front sorter 8, and the idler rollers 22 and 23 are fixed to a side wall of the sorter 6 and are guided by a guide rail 24. , 25, and is configured to be linearly reciprocally movable back and forth along the filtration and selection surface of the Glensieve 17. Further, the lower ends of the links 26 pivotally attached to the side walls are pivotally connected to the left and right front ends of the rear sorting section 9, respectively, and the eccentric cam mechanism 27 is linked to the lower rear portion so as to be swingable back and forth. There is. A pivot link 28 is pivotally attached to the lower portion of the side wall, and one end of the pivot link 28 and the shaft 2 of the idler roller 23 at the rear are pivoted.

When moved, the front sorting section 8 is adapted to reciprocate linearly. Here, the eccentric cam mechanism 27 and the link 26 constitute the second drive mechanism B, and the eccentric cam mechanism 27,
The second rod 30, the rotation link 28, the first rod 29, the idle rollers 22, 23 and the guide rails 24, 25 are the first
The drive mechanism A is configured.

Next, the Glen pan 13 and the Glen sieve 17 will be described in detail. As shown in FIG. 1, the Glensieve 17 has a leakage screening surface with a small angle β with respect to the horizontal plane.
It is erected on the front frame plates 15 and 15 in a rearwardly downward inclined posture. On the other hand, the Glen pan 13 is capable of swinging up and down about the horizontal axis P at the front end thereof so that the front frame plates 15 and 15 are movable.
The posture changing mechanism for swinging and changing the posture of the Glen pan 13 is linked. This posture changing mechanism is configured by connecting an operation wire 32 linked to a lever provided in a control unit (not shown) to an arm 33 protruding from the lower surface of the Glen pan 13. By swinging the position-holdable lever and holding it at an appropriate position, the Glen pan 13 can be changed to any tilted posture.

With the above configuration, when the amount of processed matter leaking from the receiving net 4, that is, the amount of threshing treatment is large, or when the wet grain culms are threshing treatment, the inclination angle α of the Glen pan 13 with respect to the horizontal plane is relatively large. In order to prevent the processed product from staying in the Glen pan 13, the Glen Sieve 17 speeds up the flow of the processed product to the wales in priority to the specific gravity selection process in the Glen pan 13. In addition, when the grain culms in the normal state which are not wet are threshed, and the threshing amount is small, the inclination angle α of the Glen pan 13 with respect to the horizontal plane is made small so that the specific gravity sorting process for the processed products can be sufficiently performed. In the selected processing state, the processed product is transferred to the grain sieve 17.

The posture changing mechanism for changing the posture of the Glen pan 13 can be changed by driving an electric motor or the like instead of the artificial changing structure using the operation wire as in the above embodiment. good.
