Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a whole culm-type threshing device.

[Conventional technology]

There is an all-culm-type threshing device as shown in FIG. 5, for example (see Japanese Utility Model Application No. 1-9096). This is mounted on a combine, and the cut grain culm is fed from a feed conveyor (5) onto a conveyor device (13) of a belt conveyor type. Then, the grain culm is sent to the right side of the paper surface by the transfer device (13) and fed into the handling room (14), and is threshed by the rotating handling barrel (16). Then, the single-grained grains are separated from the handling chamber (14) by the sorting section (1
It falls to 0) and is sorted.

[Problems to be solved by the device]

The above-mentioned whole culm-type threshing device has the purpose of threshing soybeans, buckwheat, and various types of crops such as rice and wheat. In this case, in crops where the pods are relatively hard and strong, such as rice and wheat, there is no particular problem even if the grain culm is strongly hit with a handling barrel to thresh, but, for example, soybeans In relatively weak crops, strong impacts from the barrel may break the pods before damaging the kernels.

It is an object of the present invention to configure the whole culm input type threshing device as described above so as not to damage the grain when threshing a particularly weak crop.

[Means for Solving the Problems]

The feature of the present invention resides in that the whole culm throwing type threshing device is configured as follows. In other words, a squeezing device that crushes the culms on the transport device is provided at an intermediate position of the transport device that feeds the cut grain stalks into the handling room, and the grain leaks between the squeezing device and the end of the transport device. In addition to the provision of a lower part, a guide path for feeding the grains that have leaked from the lower part to the sorting section located under the handling chamber is provided, and the action and effect thereof are as follows.

[Action]

With the configuration described above, the grain culm sent from the starting end side of the transport device is crushed by the pressing device at the intermediate position of the transport device. Therefore, in a particularly weak grain culm, the crushing action (the impacting action given to the grain culm is sufficiently smaller than that of the handling cylinder) causes the grain to become a single grain in some proportion.

Then, when this grain culm is further transported, grains that have already become single grains and fine straw scraps are sent to the sorting section from the leak bottom without passing through the handling room before being sent to the handling room. Become. Then, the grain culms that have not leaked from the lower part are sent into the handling chamber by the transport device and threshed.

[Effect of device]

As mentioned above, instead of sending all the grains to the handling room,
Particularly weak grain culms can be lightly threshed and singulated in advance using a squeezing device, and the grains that have been crushed can be removed without putting them in the handling room, thereby reducing the number of grains that will be damaged. It was possible to improve the performance of the all culm input threshing device.

〔Example〕

Hereinafter, a combine equipped with an all-culm throwing type threshing device according to an embodiment of the present invention will be described with reference to the drawings.

This scraping reel (2) is provided with a large number of scraping claws (2a) as shown in FIGS. 2 and 4. Then, the outermost scraping claw (2b) is made of rubber capable of being strongly deformed, and is bent outward to the extent that it slightly contacts the divider (6). As a result, the grain culm lying on the outside is squeezed inward by the scraping claw (2b) as much as possible.

Then, the grain culms cut by the reaping unit (1) pass through the lower side of the feed conveyor (5), and are fed from the grain culm discharge port (11) to a rotary drive type beater (12) and above the transfer device (7). Is released to. In this case, as shown in FIG. 3, the leading end of the conveying plate (5a) of the feed conveyor (5) is formed in a convex shape, and the leading end of the beater (12) is formed in a concave shape.

It has a structure in which (corresponding to the bottom part) is arranged at intervals in the lateral direction of the aircraft. This supply conveyor (13) has a structure in which a rubber belt (13c) is wound around a pair of rollers (13a), (13b), and the roller (13) on the grain culm outlet (11) side.
The entire supply conveyor (13) is supported so as to move up and down around the fulcrum (P ₁ ) of a), and is urged upward by a spring (8).

Further, as shown in FIG. 1, a pressure roller (15) (corresponding to a squeezing device) is arranged above the roller (13b) on the side of the handling chamber (14), and the pressure roller (15) is supplied. It is driven to rotate at approximately the same speed as the conveyor (13). As a result, the grain culm is pressed by the roller (15) and the roller (13b).
It is crushed between and and discharged onto the wire (25).

The wire rod (25) is inclined downward to the right side of the paper in FIG. 1, and the grain culms slide down toward the handling room (14). Then, the grains and fine straw scraps that have been crushed by the pressure roller (15) and have already become single grains fall downward between the wire rods (25) and from the guide passage (9) to the sorting unit (described later). It is fed onto the guide plate (24) of 10) (see Fig. 4).

On the other hand, a pair of upper and lower rollers (26a) and (26b) are provided at the end of the wire (25).
