Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of a grain culm transport system in an all culm input type combine for feeding all grain culms cut by a reaper into a handling room of a threshing device.

[Prior art] In all culm type combine and self-removing combine,
It is not possible to mow all the culms planted in the field. As a result, the operator cuts the grain culms in the part where the combine enters the field or the grain culms left uncut by the operator, and the operator cuts the harvested grain culms by hand to the threshing device, etc. And is threshing processing.

[Problems to be solved by the device]

In an all-culm input combine harvester, the grain culm transport system from the mowing section to the threshing device generally has a closed structure with a transport conveyor arranged in the duct. Grains must be fed into the entrance to the section, below the rotating auger. However, since the planted culm is scraped to the auger side above the auger and the reel is rotating, it is difficult to feed the culm well.

An object of the present invention is to make it possible for an operator to easily feed grain culms cut with a vanider or the like into a threshing device in an all culm throw type combine harvester.

[Means for Solving the Problems]

The feature of the present invention resides in that the above-mentioned all culm input type combine is configured as follows.

A feed conveyor that conveys the grain culms cut by the mowing section diagonally upward and rearward, and a feed conveyor that receives the grain culms that have emerged from the end of the feed conveyor, receives it on the upper surface, conveys it backward, and sends it into the handling chamber of the threshing device. In addition to the above, there is provided a grain culm inlet provided with a lid body that can be opened and closed in the upper portion of the supply conveyor.

[Action]

() When configured as in the present invention, there is no rotating reel (2) or the like near the lid body (6) and the grain culm input port (7) as shown in FIGS. 1 and 2, for example. , Reel (2)
The operator can easily insert the cut grain culm into the grain culm input port (7) without being disturbed by the like.

() As shown in FIG. 1 and FIG. 2, for example, below the lid (6) and the grain culm inlet (7), a supply conveyor (13) for conveying the culm to the handling chamber (14). There is nothing else that prevents the transfer of the grain culms to the handling room (14).

As a result, the worker only has to put the cut grain culm into the grain culm input port (7), and the grain culm input from the grain culm input port (7) falls onto the supply conveyor (13). The grain culm is surely sent to the handling room (14) by the supply conveyor (13).

[Effect of device]

As described above, the worker can easily and reliably send the cut grain culm to the handling room of the threshing device, and the workability of the all culm input type combine can be improved.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings for a combine for soybeans and buckwheat, which is a whole culm input combine.

As shown in FIG. 1, a rotary scraping reel (2), a hair clipper type mowing device (3), an auger (4) for bringing the cut grain culm to the front of the fuselage, and a feed conveyor for feeding the grain culm upwards ( 5) etc. are provided with a mowing unit (1), and the mowed grain culms are sent along the lower side of the feed conveyor (5) and are rotationally driven from the grain culm discharge port (11). It is discharged onto the belt type supply conveyor (13) by the beater (12).

The grain culms are fed from the supply conveyor (13) into the handling chamber (14) and threshed. Next, this structure will be described. As shown in FIGS. 1 and 2, the supply conveyor (13) has a structure in which a rubber belt (13c) is wound around a pair of rollers (13a) and (13b), and a grain outlet (11). The supply conveyor (13) is supported so as to move up and down around the fulcrum (P ₂ ) of the roller (13a) on the) side, and is urged upward by the spring (8). As shown in Fig. 2, the pressure roller (15) is also arranged above the roller (13b) on the side of the handling chamber (14). The pressure roller (15) is made of a metal cylinder with rubber. The structure is such that they are stuck together, and they are driven to rotate counterclockwise in the drawing at a speed lower than the feed speed of the supply conveyor (13).

Next, the structure inside the handling room (14) will be described. As shown in FIGS. 1 and 2, the handling cylinder (16) is rotationally driven in the handling chamber (14) around the horizontal axis (P ₃ ) in the clockwise direction of the drawing. Rasp teeth (16a) inclined with respect to the rotation direction are attached to the handling cylinder (16) while alternately changing the inclination direction.

With the above structure, as shown in FIG. 2, the grain culm is fed by the supply conveyor (13) with the tip of the grain facing to the right side of the paper, and is located between the roller (13b) and the pressure roller (15). While being crushed by, it is sent into the handling room (14) while being crushed by the speed difference between the roller (13b) and the pressure roller (15). Then, due to the hitting action from the bottom to the top due to the rotation of the handling cylinder (16) and the squeeze / rubbing action by the slap teeth (16a), the grains become single grains and the first outlet (14a) of the handling chamber (14). Fall from.

Also, the grains with branches that have not been sufficiently made into single grains are sent upward so as to be entangled with the handling cylinder (16), and the handling cylinder (16)
And the first, second, and third ceiling plates (17), (18), (19) are rubbed to form single particles, which are then removed from the handling barrel (16) or the second outlet of the handling chamber (14) ( It will fall from 14b).

Below the handling room (14), there is provided a sorting section for the falling processing objects. Next, this structure will be described. As shown in FIG. 1, a cage-like selection plate (23) and a guide plate (2
4), Karatsu (27), wind direction plate (28) for adjusting the wind direction, etc. are arranged, and the No. 1 product is collected by the No. 1 screw (29). The 2nd product is collected by the 2nd product processing rotor (31) and processed into granules.
Grains and the like that have leaked from 1) are collected as No. 2 by the No. 2 screw (33).

As shown in FIG. 1 and FIG. 2, a grain culm inlet (7) having a lid (6) which can be opened and closed upward around the horizontal axis (P ₁ ) in the upper part of the supply conveyor (13). Is provided, and the grain culms cut by a binder (not shown) or the like are fed into the feed conveyor (13) through the grain culm input port (7).

In the claims of the utility model registration, reference numerals are given for convenience of comparison with the drawings, but the invention is not limited to the configurations of the accompanying drawings by the entry.
