JP, 2008-289383, A

In the threshing device of the above document, it is possible to improve the sorting ability by sending the sorting air to the upper surface side of the Glen pan, but in order to adjust the strength of the sorting air on the Glen pan, etc. Separately, a wind force adjusting means for adjusting the air volume of the sorting air is configured by opening and closing the outlet for discharging the sorting air according to the amount of straw or by changing the number of drives of the blower fan. However, there is a problem that the cost becomes high.

In the present invention, in the threshing device for improving the sorting capacity by sending the sorting wind to the upper surface side of the Glen pan, the presence/absence of the amount of the sorting air blown to the upper surface side of the Glen pan and the switching of the strength of the sorting air are switched. It is an object to provide a threshing device that can be configured easily and inexpensively.

To solve the above problems, comprises an oscillating sorting member 31 for selection of threshing treated treated by the swinging sorting, and a blower fan 34 to Okoshifu sorting air for sorting processed product, said oscillating sorting The body 31 has a Glen pan 38 arranged on the front side, a chaff sheave 39 arranged behind the Glen pan 38 to sort and leak a processed material, and a Glen sheave 42 arranged below the chaff sheave 39. In the threshing device having a structure in which a conveying surface 38a for conveying the processed material backward is formed on the upper surface of the Glen pan 38 and the sorting air is made to flow to the conveying surface 38a side, the swing sorting body 31 is arranged. The sorting chamber 22 is provided with a Karato fan 32, which is disposed on the lower front side of the swinging and sorting body 31, and blows the screening air from the lower side toward the Glensieeve 42 and the chaff sheave 39 side. Separately from 32, it is arranged in front of the Glen pan 38 and configured to blow the selection air to the conveying surface 38a side, and is attachable/detachable in the middle of the flow path from the blower fan 34 to the conveying surface 38a side. The adjusting members 52, 54, 56 are provided, and the amount of the sorting air flowing toward the conveying surface 38a is adjusted by attaching or detaching the adjusting members 52, 54, 56, or the presence or absence of the sorting air is switched. By attaching/detaching the adjusting members 52, 54, 56, a part or all of the sorting air blown from the blower fan 34 to the Glen pan 38 side is made to flow to the Glen sieve 42 side, thereby making a sorting flow to the Glen pan 38 side. The structure is characterized in that the amount of wind is adjusted or the presence or absence of selected wind is switched.

According to the above configuration, by attaching or detaching the adjusting member, it is possible to adjust the air volume of the sorting air blown to the upper surface side of the Glen pan, or to switch the presence or absence of the sorting air. The sorting wind to the Glen Pan side is strengthened so that the straw dust can be skipped in the early stage of swing sorting for efficient swing sorting, while the material to the Glen Pan side is easily sorted if the material easily flies and is easily scattered outside the machine. The wind can be weakened or eliminated to prevent the grains from scattering outside the machine. In addition, the configuration is simplified as compared with the configuration in which a separate sorting air adjusting unit that operates the rotation speed of the blower fan or automatically opens and closes the sorting air outlet according to the amount of straw is provided. At the same time, the cost can be kept low.

Further, by attaching/detaching the adjusting members 52, 54, 56, a part or all of the sorting air blown from the blower fan to the Glen pan 38 side is made to flow to the Glen sieve 42 side, so that it flows to the Glen pan 38 side. If the structure that adjusts the air volume of the sorting air or switches the presence or absence of the sorting air is used, the versatility is improved because the destination and the air volume of the sorting air can be switched with a simpler configuration. In addition, the cost can be kept low. In addition, since the sorting wind that has been diverted to weaken the sorting wind to the Glenpan side can be used to improve the sorting capacity on the Glensive side that does not affect the out-of-machine scattering, efficient sorting work is performed according to the harvested product. be able to.

It should be noted that the sorting chamber in which the swing sorting body is disposed is provided with a Kara-mino fan, which is placed on the lower front side of the swing sorting body 31, and blows the sorting wind from the lower side toward the Glensieeve 42 and the chaff sheave 39 side. According to the blower fan, which is an auxiliary fan that is disposed in front of the Glen pan and blows the sorting air to the conveying surface side, separately from the Kara-mino fan, the sorting fan is provided on the upper surface side of the Glen pan by the auxiliary fan. Since it can be sent stably, the sorting ability is more stable and improved.

A lower flow path is formed between the lower opening 53 provided on the front surface side of the rocking/sorting body 31, and a lower flow path is formed therein. The mechanism is configured so that the sorting air sent by the auxiliary fan 34 can be sent to the upper and lower flow paths. At this time, the upper Glen pan 44 is arranged so as to project above the upper opening 51, and the Glen pan 38 is arranged so as to project above the lower opening 53 so that the processed material is It is possible to efficiently prevent falling from the upper opening 51 (lower opening 53).

Specifically, the switching mechanism divides the selected wind of the auxiliary fan 34 into both the upper surface side (upper flow path) of the Glen pan 38 and the upper surface side (lower flow path) of the Glen sieve 42, and the auxiliary fan. A lower blowing state in which the sorting wind of 34 is blown only to the upper surface side (lower passage) of the Glen sieve 42, and an upper blowing state in which the sorting wind of the auxiliary fan 34 is blown only to the upper surface side (upper passage) of the Glen pan 38. It is configured so that it can be switched to. The detailed configuration of the switching mechanism will be described later.

With the above-described configuration, the processed material introduced to the sorting section 22 side is swing-sorted by the swing sorting body 31, and is separated into grains and straw wastes by the sorting wind blasted by the Karako fan 32, the auxiliary fan 34, and the like. To be selected. Specifically, the processed matter that has leaked from the rocking sorting body 31 is almost unaffected by the sorting wind blown toward the Glensieeve 42 and the chaff sheave 39 side by the Karawan fan 32, and the center of the sorting unit 22 in the front-rear direction (1 No. 1 spiral 36) and the No. 1 object which falls slightly forward from the No. 1 helix 36 and is collected by the No. 1 spiral 36 and the No. 2 helix 37 after falling slightly behind the No. 1 helix 36 due to the influence of the sorting wind. The second waste collected by the above is wind-sorted, and the straw wastes and the like are blown to the discharge section 8 side by the sorting wind.

The No. 1 product is conveyed by the No. 1 spiral 36 and the grain lifting device 46, and is stored in the Glen tank 7 as grains. The No. 2 product is returned again to the upper side of the swing selection body 31 in the selection unit 22 by the No. 2 spiral 37 and the reduction device 47, and the wind selection is performed.

Next, the switching mechanism will be described with reference to FIGS.
FIG. 4(A) is a front perspective view of the swing selecting body showing a state in which a ventilation plate is installed on the upper switching plate, and FIG. 4(B) shows a state in which a ventilation plate is installed on the lower switching plate. FIG. 5A is a front perspective view of the rocking sorting body, and FIGS. 5A to 5C are diagrams showing a state in which sorting air is blown from the auxiliary fan that is switched by the switching mechanism.

The switching mechanism is configured on the front side of the swing selecting body 31 formed in a step shape above and below the Glen pan 38. Specifically, an upper switching plate (adjusting member) 52 that switches between opening and closing of the upper opening 51, a lower switching plate (adjusting member) 54 that switches between opening and closing of the lower opening 53, and a sorting wind from the auxiliary fan 34. And a shield plate (adjustment member) 56 that shields a flow path extending to the lower switching plate 54 side, and by attaching and detaching each switching member to the front side of the rocking sorting body 31, the auxiliary fan 34 is connected to the Glen pan. It is configured such that the sorting air blown to the 38 side can be guided and the destination of the sorting air can be switched.

The upper switching plate 52 is a plate-shaped member that is fixed to the front side of the Glen pan 38 by a bolt so as to be detachable, and is formed in a frame shape. Select either one of the upper ventilation plate 52A (see FIG. 4(A)) that allows the sorting wind of FIG. 4 and the upper shielding plate 52B (see FIG. 4(B)) that shields the sorting wind from the auxiliary fan 34. And is attached to the upper opening 51 of the swing selecting body 31. As a result, it is possible to switch whether or not to flow the sorting air on the upper surface side of the Glen pan 38. It should be noted that the mesh portion 52a only needs to have a configuration through which the sorting wind passes.

Further, the upper switching plate 52 is inclined from the front end side of the Glen pan 38 toward the upper front side, and its upper end side is bolted to a pair of left and right upper bolt fixing portions 57, 57 provided on the front side of the upper Glen pan 44. While being fixed, the lower end side is bent and formed in the horizontal direction along the front end side of the Glen pan 38, and is bolted by the pair of left and right middle bolt fixing portions 58, 58 provided on the front side of the Glen pan, whereby the upper opening portion is formed. It is configured to be detachable from the 51.

The lower switching plate 54 is a plate-shaped member that is fixed to the front surface side of the gren sheave 42 by a bolt so as to be detachable. The lower switching plate 54 is formed in a plate shape and covers the inside of the frame with a mesh portion 54a so that the auxiliary fan 34 can be removed from the auxiliary fan 34. Select either one of the lower ventilation plate 54A (see FIG. 4(B)) that allows the sorting air of FIG. 4 and the lower shielding plate 54B (see FIG. 5(A)) that shields the sorting air from the auxiliary fan 34. Then, it is configured to be attached to the lower opening portion 53 of the swing selecting body 31.

The lower switching plates 54 are inclined from the front end side of the gren sheave 42 toward the front upper side, and a pair of left and right lower bolt fixing parts are provided on the front side of the gren sheave 42 and the middle lower part of the gren pan 38, respectively. By being bolted to 59, 59, 59, 59 (four places in total), they are configured to be attachable to and detachable from the lower opening 53.

The shielding plate 56 is a plate-shaped member that is fixed to the front surface side of the Glen pan 38 by a bolt so as to be detachable, and blocks a midway portion of a flow path through which the sorting wind from the auxiliary fan 34 flows. By being attached so as to project toward the front side of the Glen pan 38 (swing selection body 31), the selection air from the auxiliary fan 34 can be introduced to the upper flow path. Further, by removing the shielding plate 56, the sorting air from the auxiliary fan 34 can be sent to the lower flow path.

Further, the shielding plate 56 is a plate-shaped member extending in the front-rear direction, the rear end side thereof is fastened together with the upper switching plate 52 to the middle bolt fixing portions 58, 58, and the left and right end sides thereof are formed to be bent upward. Then, the frame side bolt fixing portions 61, 61 provided on the front end sides of the plate frames 43, 43 are fixed by bolts (four places in total), so that they are detachably configured.

In the switching mechanism having the above-described structure, the upper ventilation plate 52A is bolted to the upper opening 51, the lower ventilation plate 54A is bolted to the lower opening 53, and the shielding plate 56 is removed to remove the auxiliary fan 34 from the auxiliary fan 34. It is possible to switch to the split flow state in which the selected wind is sent to both the upper surface side of the Glen pan 38 and the upper surface side of the Glen sieve 42 (see FIG. 5(A)).

According to the split flow state of the configuration, the processed products on the chaff sheaves 39 in the upper flow path of the rocking selection body 31 and the processed products on the Glen sieve 42 in the lower flow path are subjected to wind selection by the selection wind from the auxiliary fan 34. Then, the processed products leaked from the rocking sorting body 31 (Glensieeve 42) side are wind-sorted by the stronger sorting wind from the Karatan fan 32, so that the sorting performance can be uniformly sorted in the vertical step. improves.

Further, the switching mechanism is such that the upper shield plate 52B is bolted to the upper opening 51, the lower ventilation plate 53A is bolted to the lower opening 53, and the shielding plate 56 is removed, so that the auxiliary fan 34 is removed from the auxiliary fan 34. It is possible to switch to the lower air blowing state in which the sorting air is blown only to the Glensieeve 42 side (see FIG. 5(B)).

According to the lower blast state of the configuration, especially in the case of a product type in which the filtration amount of the processed material is small, it is possible to prevent the selected air from being blown onto the chaff sheaves 39 of the rocking sorting body 31, and to process the chaff sheaves 39. Since the objects that have been oscillated and sorted to some extent and that have fallen on the Glensieeve 42 can be wind-selected by the sorting wind, it is possible to efficiently prevent the processed matter remaining on the chaff sheaves 39 from being scattered outside the machine more than necessary. . That is, in the lower blast state and the diverted state, the selection air from the auxiliary fan 32 blown to the Glen pan 38 side is blocked (weakened), and the selection mechanism does not affect the out-of-machine scattering. Air can be introduced to the lower flow path (Glensieve 42) side to improve the sorting ability.

Further, in the switching mechanism, the upper ventilation plate 52A is bolted to the upper opening 51, the lower shielding plate 53B is bolted to the lower opening 53, and the shielding plate 56 is bolted, thereby the auxiliary fan. It is possible to switch to a state in which the selected wind from 34 is blown only to the Glen pan 38 side (see FIG. 5C).

According to the upper blowing condition of the configuration, the screening air from the auxiliary fan 34 is guided to the upper flow path by the shielding plate 56, so that the screening air sent to the Glen pan 38 and the chaff sheave 39 side can be strengthened. it can. Therefore, in particular, when selecting a variety having a large filtration amount from the chaff sheave 39, the threshing-treated product can be immediately selected by the selection wind from the auxiliary fan 34 at an early stage, so that the selection efficiency is improved.

According to the configuration of the switching mechanism described above, the upper side of the rocking sorting body 31 is selected according to the type of the grain culm to be mowed (threshing/sorting) by the general-purpose combine capable of harvesting various culms. By selecting the presence or absence and the strength of the selection air blown to the flow path and the lower flow path, the selection capacity can be appropriately changed. Further, the presence or absence or the strength of the sorting wind is switched by attaching and detaching the upper switching plate 52, the lower switching plate 54, and the shielding plate 56, so that the cost can be kept low.
