Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a feeder house front plate device in a combine.

(Prior art) A combine harvester is a so-called general-purpose combine harvester, in which grain stalks scraped by a scraping reel are mowed with a cutting blade, and the harvested grain stalks are carried to a handling room by a chain conveyor of a feeder house and threshed. It is applied to harvest various harvested crops.

(Problems to be solved by the invention) As described above, in the general-purpose combine, there are many objects to be cut, and in the reel tine type scraping device in which the forms of the self-removing combine and the cutting part are different, Depending on the type and culm length, the crops cut may become stagnant and head loss may increase.

Therefore, the shape of the front plate of the platform is changed, and a conveyor is installed just behind the cutting blade. However, these devices have limited adaptation crops.

In addition, attaching a conveyor has the disadvantage that the cost of the device is high.

Therefore, the object of the present invention is to solve the above-mentioned conventional drawbacks and to obtain a combine in which the crops are smoothly transferred from the reel tines to the feeder house augers.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention is to cut the grain stalks scraped by the scraping reel with a cutting blade, and the spilled grain stalks are fed to the chain conveyor of the feeder house. In the case of being transported to the handling room and threshing, a front plate for transferring the harvested culm to the scraping auger is provided in the front part of the feeder house behind the cutting blade, which is configured to be rotatable around the front end as a pivot. A feeder house front plate device was devised in which an auxiliary plate rotatably provided at the rear of the grain stalk transfer front plate with a rear end as a fulcrum was provided toward the harvested grain stalk transfer front plate.

(Effect of the Invention) According to the technical means of the present invention, the front end of the feeder house at the rear of the cutting blade is caused with the front end as a base point, and when the reel tine is moved along the rotation trajectory, the scraper auger of the feeder house from the reel tine. The dead space between them is reduced, so that the inheritance of crops during that time is smoothly performed and the culm is not stagnant.

Further, an auxiliary plate, which is rotatably provided with the rear end as a fulcrum of rotation, is provided behind the front plate for receiving the harvested grain and culm, so that the front plate for connecting the harvested grain and culm is provided. There is no dead space behind the front plate, and the scraping auger feeds smoothly.

Furthermore, when soybeans are harvested, backflow of beans is prevented, and head loss is reduced. Furthermore, it is possible to prevent soil from entering.

As described above, the head loss is reduced, the applicable crops are expanded, the crops are applied to all crops, and the cost is lower than that of the conveyor.

(Example) Hereinafter, the Example shown in drawing is described.

First, the general-purpose combine will be described.

In FIG. 2, the grain culm is scraped by the scraping reel (1) and cut by the cutting blade (2), and the cut grain culm is transferred from the scraping auger (3) to the chain conveyor (4) of the feeder house (4). It is carried to the handling room (6) in 5), and the screw type handling barrel (7)
Be threshed in.

The threshed ones are dropped from the net (8) onto the rocking sorting board (9) and sorted.

Those threshed on this rocking sorting board (9) are sorted, but only the long straws are carried toward the rear dust outlet.

Also, the items sorted by the rocking sorter (9) are sorted by the sorting wind by the Kara (11) or the blowing fan (12), and the grains are sorted into the first gutter (13) The number two gutter (1
Grains that fell to 4) and fell to the first gutter (13) were lifted (1
It is carried to a paddy tank (not shown) via 6), and the second product is carried to the rocking sorting board (9) via the reduction cylinder (18).

Straws from the handling room (6) are discharged from the discharge port (6a) by the discharge blade (7a).
(15) is a crawler equipped with a thresher, and (19) is an elevating cylinder of a feeder house.
(20) is the divider and (21) is the driver's seat.

In this combine harvester, the present invention has been devised so that the crop can be smoothly transferred from the reel tines (1) to the scraping augers (3) of the feeder house (4).
As shown in FIG. 1, a front plate (22) for transferring the cut culm to the scraping auger (3) configured to be rotatable around the front end (23) as a fulcrum at the front of the feeder house behind the cutting blade (2). ) Is provided, the front plate (22) follows the rotation locus of the reel tine (1) by inducing the front plate (22), so that the crop from the reel tine to the feeder house auger (3) is The inheritance will be carried out smoothly and the culm will not be stagnant.

In this case, two sheets are stacked with the feeder house bottom plate (24), but the auxiliary plate (25) is provided with a rotation fulcrum (opposite to the rotation fulcrum (23) so that the feeding by the scraping auger can be further smoothly performed. It is configured such that it can be rotated toward the scraping auger (3) side around the center 26).

Then, it is preferable that the auxiliary plate (26) is connected by an interlocking mechanism so that the auxiliary plate (26) can be rotated in the direction in which the front plate (22) is rotated.

The simple mechanism is to use fan-shaped gears (2
7) Make the (28) rotate integrally with the rotation fulcrums (23) (26).

The above rotation of the front plate (22) is performed manually so that it can be fixed at the rotation position by an appropriate lock mechanism. However, the reel is lifted and the feeder house front plate is rotated. And may be linked.

That is, as shown in FIG. 3, when connecting the pulling wire (41) of the front plate (22) to the frame (43) of the reel (1), the roller (4) of the sweeping auger cover (44) is connected.
2) Connect via.

It should be noted that, unlike the self-removing type, the triggering portion of the general-purpose combine harvester is a reel, so the divider function is also different.

The current one allows the divider to be adjusted up and down, depending on the type and conditions of the crop.

Where there are weeds, the divider should be raised so that the weeds will not be covered, and if the grain culm is lodged, the divider will be scooped down to scoop the lodge.

Where the crop conditions are changing in one field, such as standing hair, lodging, weeds, the driver must go to the divider side to adjust, in which case the divider on the left side should be plunged into the uncut stem. It is difficult to adjust because there is.

Therefore, it is recommended that the left and right dividers can be adjusted up and down in the driver's seat (21).

That is, as shown in FIGS. 4, 5, and 6, the divider (20) can move up and down at the pivot fulcrum (29), and the arm (extended from the fulcrum (29) ( 20a)
Connect the wire (31) (30) to the
1) is inserted into the mowing pipe (33) through the guide roll (32), and the lever (3
Connect to one end (39) of the bottom of 5).

The above is the connection between the left divider (20) and the lever (35), but the same applies to the right divider (20).
The wire (31) passes through the guide roll (38) and the lever (3
Connect to the other end (40) of the lower end of 5).

Therefore, when the lever (35) is swung about the fulcrum (37), the lower ends (39) (40) of the lever pull or tighten the wires (31) (31), so that the divider (20) is a fulcrum. Moves up and down around (29). (36) can be locked in the adjusted position with a lever latch. According to the above-mentioned configuration, the driver can adjust the divider at hand according to the crop condition, and the work can be performed efficiently, and the head loss is reduced.

In this way, the idea is to smoothly transfer crops from the reel tines to the scraping augers in the feeder house,
There is no stagnation in the culm.
