Description

Whole Culm Charging-type Combine Harvester}

The present invention relates to a full-length input combine (hereinafter, simply referred to as a "combiner") equipped with a threshing apparatus for inputting and threshing the whole harvested grain stem removed by the harvesting unit.

In the said combine, the 2nd processed material (equivalent to a reduced processed material) sent out from the sorting part is reduced through a reduction | restoration processing apparatus, and it is comprised so that it may be re-selected into dust, such as a grain and debris, by a rocking | fluctuation sorting apparatus.

As a conventional combine of this kind, for example, Japanese Patent Laid-Open No. 11-155347 (see paragraph [0022] and Fig. 2, hereinafter referred to as "Patent Document 1") and Japanese Patent Laid-Open No. 11-266670 (See paragraphs and Figure 3. Hereinafter, referred to as "Patent Document 2"). In patent document 1, the 2nd processed material is returned from the screw conveyor 23 for secondary water collection | recovery to the oscillation sorting case 20 through the reduction apparatus 24. FIG. In patent document 2, the 2nd process material is reduced-feeded to the front part of the oscillation sorting case 23 via the horizontal feed screw conveyor 27 and the vertical feed screw conveyor 20. As shown in FIG.

Moreover, it is described in Unexamined-Japanese-Patent No. 7-274693 as another conventional combine (see Paragraph 1 and FIG. 1, FIG. 2, hereafter called "patent document 3"). In this patent document 3, an auxiliary winnowing fan 18 is provided in the vicinity of the start end of the sorting device B, and is scattered from the discharge port 20 of the second reducing device 9 to sort the sorting device B. It is comprised so that the sorting wind from the auxiliary pull 18 may perform a selective action | action with respect to the 2nd thing (reduced process material) reduced by the process.

In the combine input-type combine, the second processed material (reduced processed material) returned from the sorting unit due to a large amount of debris and the like generated in the handling chamber because the whole from the bottom to the end of the harvested grain stem is supplied and threshed. A lot of debris to mix in). When the second treatment material is reduced to the rocking screening device in many states such as mixing debris and mixed into the threshing processing material dropped from the support network of the handling room to the rocking screening device, the screening capacity and the screening accuracy of the rocking screening device are deteriorated. Easier

When the technique disclosed in Patent Literature 3 is adopted, the reduced processed material from the reduction conveying device is supplied to the oscillation screening device after being subjected to the screening action, but in this configuration, it tends to be a high cost or a complicated structure for installing an auxiliary pull or the like. there was.

It is therefore an object of the present invention to provide an inter-loading combine that can be obtained at a low cost and simple structure that can efficiently and accurately sort by a shaken separator regardless of the reduction of the second treatment. .

In order to achieve the above object, the present invention is a full-time input combine configured to thresh the whole harvesting grain stem,

The threshing apparatus has a handling chamber which threshes the whole harvesting grain stem by a handling container, and the rocking | separation sorting apparatus which sorts-processes the threshing process material which fell from the support net of this handling chamber by the sorting wind which flows to the back of a machine main body. A sorting chamber and a reduction conveying apparatus for reducing and supplying the reduced processed material from the sorting chamber to the sorting chamber, wherein the partition wall provided between the upper plate of the handling chamber and the upper end of the supporting network and the threshing apparatus A preliminary sorting space for preliminarily sorting the reduction processed material is formed by one horizontal wall, and the discharge port of the reduction conveying apparatus is in communication with the sorting chamber through the preliminary sorting space.

According to this characteristic structure, since the said preliminary sorting space communicates with the sorting room of the sorting part, a part of the sorting wind which flowed out from the sorting room flows into a preliminary sorting space, and flows this space backward. When the second processed material (reduced processed material) from the sorting part is discharged from the reduction conveying device, the second processed material is preliminarily sorted into grain and dust by the sorting action by the inflow sorting wind, and then the shaking sorting device in the sorting room. Fall on. In addition, for the sorting wind flowing in the preliminary sorting space or its vicinity toward the rear of the machine main body, lighter dust is scattered to the rear of the main body than the grain, and is discharged out of the main body of the machine together with the dust from the sorting chamber, or the oscillation sorting is performed. The device falls behind the grain (downward in the workpiece conveyance direction). Thereby, even if there is much mixed dust in the 2nd process material returned from a sorting part, it can pre-select by grain and dust by sorting wind, and can isolate | separate dust from a grain beforehand, and can reduce | restore it to a shaking-separation apparatus. In some cases, it is also possible that the sorted dust flows out by the sorting wind and is discharged out of the main body of the machine without being returned to the swing shaking sorting device.

Therefore, according to the present invention, regardless of the incorporation of the reducing treatment, the reduction treatment can be efficiently and accurately sorted by the rocking dividing apparatus together with the threshing treatment from the supporting network. Therefore, the efficiency of the sorting process by a sorting part improves. In this invention, since this point becomes possible only by providing a partition wall and uses the sorting wind from a sorting room for preliminary sorting, it is advantageous in terms of cost and structure.

In order to use the sorting wind from the sorting chamber for preliminary sorting, in one preferred embodiment, a blowing mechanism for supplying the sorting wind to the sorting chamber is provided at the front end of the swinging sorting apparatus, and the blowing mechanism is the sorting wind. It is comprised so that supply to the said preliminary sorting space is possible.

Moreover, in one preferable embodiment, the said discharge port is provided in the one horizontal side wall of the said threshing apparatus, The guide surface which distribute | distributes the said reduction processed object in the front-back direction is provided in this discharge port. According to this characteristic structure, the area which can be used for preliminary sorting is expanded in the machine main body front and rear direction so that the reduced processed material discharged | emitted from the discharge port of the reduction conveying apparatus may distribute | distribute to the machine main body front-back direction by a guide surface. As a result, the reduced processed matter flowing out through the discharge port is more likely to receive the action of the sorting wind flowing into the preliminary sorting space from the sorting chamber, and is sorted more precisely with grain and dust and then reduced to the swing sorting apparatus. Therefore, the efficiency of the sorting process from the sorting room performed after preliminary sorting also improves further.

Moreover, in one preferable embodiment, the said discharge port is provided toward the lower part of the said preliminary sorting space, and the said guide surface is inclined downward and provided in this discharge port. This configuration is advantageous in that the reduced treated product flowing out of the discharge port is hard to reach the handling container.

In one preferable embodiment, the said discharge port opens in the lower side of the front end of this oscillation screening apparatus in the conveyance direction of the process of the oscillation screening apparatus. According to this point, the area | region in which threshing process material falls from the support network of the handling chamber on the shaking-separation apparatus, and the area | region in which the reduction process object falls from the said discharge port are disperse | distributed mutually in the front-back direction (process delivery direction). Therefore, it is difficult for both treatments to be mixed on the rocking dividing apparatus, and it is easily avoided that the layer thickness of the treatments to be deposited is locally thick.

In one preferred embodiment, the axis of rotation of the handling cylinder extends to one side of the machine main body with respect to the left and right center lines of the swing sorting device, and the other side of the machine main body is sandwiched between the left and right center lines and the preliminary sorting. The space is provided so that the said shaking | movement sorting apparatus may face downward.

When comprised in this way, since a handling barrel also shifts to one side of a main body of a machine, the horizontal width of a preliminary sorting space is ensured more as a ratio of the width of the whole threshing apparatus. In this way, the discharged reduced product is more widely dispersed, and the sorting action by the sorting wind is further promoted. Therefore, even in the compact threshing apparatus whose width | variety is comparatively narrow, the precision which pre-selects a reducing process with a grain and dust further improves.

Moreover, also in the sorting process performed after a reducing processed object falls from the preliminary sorting space to the downward rocking | separation sorting apparatus, it is advantageous at the next point. That is, since the shaft center of the handling cylinder rotation and the discharge port of the reduction conveying apparatus are arranged in a horizontal direction by interposing the left and right center lines of the swing sorting device, the area where the threshing processing material falls from the support network of the handling chamber on the swing sorting device and the discharge port. The dispersion is dispersed from each other in the transverse direction with the region in which the reducing treatment falls. Therefore, it is easily avoided that both treatments become difficult to mix on the rocking separator, and that the layer thickness of the treatment deposits is locally thick.

In one preferred embodiment, a stopper member is provided below the preliminary sorting space to prevent the reduced processed material preliminarily sorted in the preliminary sorting space from moving in the transverse direction on the rocking shake sorting apparatus. According to this configuration, the stopper member is more ubiquitous toward the discharge port of the reduction treatment apparatus than the left and right centerlines of the swing sorting apparatus. Therefore, neither the reduced processed material which fell to the shaking-separation apparatus after preliminary sorting, and the threshing processed object which fell to the shaking-separation apparatus from the support network are difficult to move on a rocking | crossing sorting apparatus horizontally for a stopper member, and it becomes difficult to mix with each other. Therefore, it is difficult to mix both the processed materials further on the rocking | flux sorting apparatus.

Moreover, if the said stopper member is extended so that the space | interval from this stopper member to the said left-right centerline may become smaller so that it may become smaller in the downward direction in the process material conveyance direction of the said shaker separator, between the stopper member and the horizontal frame of a shaker separator. The reduced processed material that has fallen from the discharge port diffuses in the horizontal direction as it is conveyed by the rocking separator. Therefore, the reduced processed material tends to be separated into grains and dusts along with the transfer.

In one preferable embodiment, the said partition wall is provided with the threshing machine main body frame extended in the machine body front-back direction, and the sheet metal member located between this machine main body frame and the upper plate of the said handling chamber. Therefore, even if no special strength member is provided, by using the machine body frame for the strength member, the strength excellent in the partition wall can be advantageously obtained in terms of cost and structure.

Advantageous effects and operational effects exerted from the other feature configurations and the feature configurations will become apparent by reading the following description with reference to the accompanying drawings.

Second Embodiment

Hereinafter, the combine which concerns on 2nd Embodiment of this invention is demonstrated, referring FIGS. 17-20. In addition, about the component common to the thing of 1st Embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

The main characteristic peculiar to 2nd Embodiment is below the preliminary sorting passage (an example of the preliminary sorting space) 68, and the reduced processed material preliminarily sorted by this preliminary sorting passage 68 is carried out on the shaking-separation apparatus 32. The stopper member 243 which suppresses moving to a horizontal direction is provided. When this point is explained in more detail, the handling cylinder 31 has the machine shaft horizontal side wall (left and right side wall of the threshing apparatus) whose rotation axis center X is larger than the left-right centerline Y of the rocking | fluctuation sorting apparatus 32. Is disposed on the opposite side to the discharge port 54 of the (60). That is, the axis of rotation X of the handling cylinder 31 is extended to the machine body one side with respect to the left and right center line Y of the swing sorting device 32, and the left and right center lines Y are sandwiched. A preliminary sorting passage 68 is provided so that the swing sorting device 32 is downwardly deviated. Then, a large workpiece stopper member 243 is provided on the upper surface side of the grain pan 32a of the swing sorting device 32 and shifted toward the discharge port 54 side than the left and right center lines Y.

This stopper member 243 consists of a strip | board material installed standing on the process surface of the grain pan 32a, and the process material on the grain pan 32a exceeds the said stopper member 243, and is different from the one horizontal side. It is comprised so that movement to the horizontal side of a side can be suppressed. In addition, the stopper member 243 is provided to the swing sorting device 32 such that the distance L to the left and right centerlines Y of the swing sorting device 32 becomes smaller as it reaches the lower side in the workpiece conveyance direction. Inclined with respect to the workpiece conveyance direction. That is, this stopper member 243 is extended in the machine main body front-back direction so that the space | interval L from the left-right centerline Y to the stopper member 243 may become smaller as the machine main body rearwards. Thereby, the workpiece | work on the grain pan 32a between the stopper member 243 and the horizontal frame 32e of the shaking-separation apparatus 32 of the side closer to this is so that the shaking-separation apparatus may reach | attain below the conveying direction. It becomes easy to diffuse in the horizontal direction of 32.

The handling cylinder 31 rotates toward the left and right center line Y of the swing sorting device 32 from the side where the handling cylinder 31 is unevenly located below the rotation axis X (see the arrow in Fig. 19). . For this reason, the threshing processed material drop-fed and supplied from the support net 39 to the grain pan 32a scatters in the rotation direction (FIG. 19 right direction). On the scattering side, the reduced processed material from the sorting portion B is discharged from the discharge port 54 to the grain pan 32a. However, in the present invention, since the handling cylinder 31 is unevenly distributed with respect to the oscillation screening device 32, the threshing treatment product is dispersed in the horizontal direction on the grain pan 32a, and the deposited layer thickness is as small as possible. In addition, since the threshing process material from the handling chamber 30 and the reducing process material from the sorting part B become difficult to mix for the stopper member 243, mixing of grain and debris is suppressed. Since the processed material on the grain pan 32a between the stopper member 243 and the sorting device close to the frame 32a spreads laterally as it reaches the rear side, the sorting process is promoted.
