DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a receiving net stretched below a handling cylinder, a swing sorting plate provided below the receiving net, and a swing sorting plate provided at a front portion of the swing sorting plate. The present invention also relates to a sorting structure of a threshing apparatus in which a filter for coarse sorting is disposed at a rear end of a front Glen pan.

[0002]

2. Description of the Related Art In a sorting structure of a threshing apparatus of this kind, as disclosed in Japanese Patent Application Laid-Open No. 2-219517, a material that has been subjected to leakage treatment at the front of a handling room containing a large amount of grains is filtered. It was configured so that sorting could be performed efficiently by roughly sorting by body.

[0003]

The threshing apparatus described above has a filter having a relatively small leak port before a chaff sieve in which the ratio of dust, such as broken straw and trash, in the leaked material is increased by a sorting action. By placing the body, the idea is to collect the grain quickly with less contamination of the dust. By the way, even if a filter body is provided on the front side of the chaff sheave, eliminating grains transferred from the filter body to the chaff sheave, that is, completely rough-sorting the leaked material in the front of the handling room is firstly performed. Although it is not possible, it has been found that when the actual sorting state is well understood, the rate at which the kernels are transferred from the filter to the chaff sieve is greater than expected. An object of the present invention is to enhance the coarse sorting action of a filter and to further improve the grain collection efficiency.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a receiving net extending below a handling cylinder, a swing sorting case provided below the receiving net, and a swing sorting case. In the sorting structure of a threshing device in which a filter for coarse separation is disposed between a front Glen pan provided at the front of the case and a chaff sheave disposed behind the pan, the filter is rockingly separated. It is characterized in that a vibration mechanism that swings in the left and right or up and down directions with respect to the case is provided.

[0005]

According to the above construction, the processed material conveyed on the filter body is not only loosened by being swayed in the transfer direction, that is, in the front and rear direction, but also swayed in the left and right or up and down directions by the vibration mechanism. Because the loosening effect will be added,
The action of loosening and stirring given to the processed material can be strengthened more than before, and the rough sorting action on the filter can be further promoted. This works effectively, for example, even when the amount of the processed material is large or in the case of wet threshing.

[0006] Since the filter body is disposed between the front and the back of the grain pan and the chaff sieve, the grains accumulated in the lower layer of the processed material layer formed by the specific gravity difference sorting of the Glen pan are passed to the lower sorting section. While dropping quickly, the paddy with the branches and straw chips accumulated in the upper layer can be sent to the rear rough sorting chaff sieve without dropping as much as possible. In other words, focusing on the fact that the sorting operation of the grains is performed most efficiently in the initial stage of the coarse sorting, the grains collected in the lower layer at the rear of the grain pan are collected at once by the filter.

[0007] Therefore, the vibration mechanism moves the filter body left and right or up and down, thereby imparting more agitation and loosening effects to the processed material, thereby further improving the grain collection efficiency in the initial stage of coarse sorting. The transfer speed in the front-rear direction on the filter body is not significantly faster or slower than when the vibration mechanism is not provided, and there is no inconvenience that the transfer condition is greatly disturbed by adding the vibration mechanism.

[0008]

As a result, the filter body between the grain pan and the chaff sheave is swayed in a direction other than the transport direction of the processed material, so that the collection efficiency of the filter body can be further improved without adversely affecting the conveyance state. A great sorting structure could be provided. For example, it is conceivable to increase the area of the grain by extending the filter body rearward to increase the chance of collecting kernels. In this case, however, the leakage treatment at the rear of the handling room where the proportion of processed materials other than kernels increases. While objects are also subject to leakage,
The thing of this application is advantageous in that only the leaked material in the front of the handling room where the ratio of the processed material other than the grain is small as in the related art is to be leaked.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 6 shows a threshing apparatus A of the whole culm input type combine which includes a threshing unit 1 and a sorting unit 6. Threshing unit 1
An axial-flow-type handling cylinder 2 rotating around a longitudinal axis is supported around a handling chamber 3, and a receiving net 4 is stretched below the handling cylinder 2. By arranging the toothing 5 in a spiral shape on the outer circumference of the stalk, the stem to be threshed is transported backward in a state where the threshing action is given.

The sorting section 6 includes a swinging sorting case 7, a karamino 8,
The first and second collection units 9 and 10 are provided. The swing sorting case 7 is provided with a front Glen pan 11, a chaff sheave 12, a rear chaff sheave 13, and the like. A resin front sheave (filtration), which is a filter for coarse sorting, is provided at a position behind the front Glen pan 11. (Corresponding to the body) 14. A large number of square holes 15 each having a side of 15 mm are formed in the front sheave 14.

As shown in FIGS. 1 and 2, the front sheave 14
Is provided with a vibration mechanism B that swings the left and right with respect to the swing sorting case 7. That is, link members 16, which are rotatable around the vertical axis X on the left and right of the rear end of the front Glen pan 11,
16 and the rear end of each link member 16 and the front sheave 14 are pivotally connected to each other.
Fixing member 18 made of square pipe erected between 7, 17
And the front end of the left link member 16 is pivotally connected by a coupling member 19 to form the vibration mechanism B.

A gap is formed between the front sheave 14 and the left and right frames 7a of the swing sorting case 7 in the left and right direction, and the front end of the sheave overlaps below the rear end of the front Glen pan 11. It is arranged. The operation will be described below. The vertical axis X and the fixed member 1 are moved with the forward and backward swing of the swing sorting case 7.
8, the distance between the link members 16 and 1 changes accordingly.
6, the front sheave 14 swings right and left.

That is, in order to increase the grain recovery rate, the size of the square hole 15 of the front sheave 14 may be increased.
This will increase the mixing ratio of waste such as broken straw,
If the vibration mechanism B is adopted, foreign substances such as straw chips and dust can be sent backward without dropping from the front sheave 14 while quickly dropping grains without increasing the size of the square hole 15 too much. As a result, the rough sorting performance can be improved.

As shown in FIGS. 2 and 3, a shift screw 20 having blades 20a and 20b having helical directions different from each other in left and right portions is provided above the front Glen pan 11.
Is provided, so that the processed material on the front Glen pan 11 that is biased left and right can be transferred to the left and right central portions.

As shown in FIG.
