Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain discharge hopper for discharging grain from a threshing machine or the like.

Conventionally, when discharging grains from a threshing machine, etc., the grains were discharged into a paddy bag from the outlet at the bottom of the paddy hopper, which communicates with the top of the paddy hopper. Because the amount of rice stored was small, and the paddy hopper was installed eccentrically with respect to the center of the machine, the balance of the machine could not be maintained, resulting in unstable running.

In the present invention, a rotary hopper whose interior is divided into a plurality of divided chambers is rotatably provided in the upper part of the grain lifting cylinder, a fixed hopper is provided below this, and an opening/closing opening provided at the bottom of the divided chamber is fixed to the rotary hopper. The purpose of the present invention is to provide a grain discharge hopper which can increase the storage amount of grain by selectively communicating with the hopper, and can also maintain running stability by making the balance of the machine body good. .

Embodiments of the present invention will be described in detail below with reference to the drawings. In the figure, numeral 1 indicates a combine harvester, and numeral 3 indicates a threshing section mounted on a traveling device 5.

Reference numeral 7 denotes a handling barrel provided in the threshing section 3, 9 a conveying spiral provided horizontally at the bottom of the threshing section 3, and 11 a grain lifting cylinder communicating with the conveying spiral 9, in which the grain lifting spiral 13 is installed. It is rotatably provided.

15 is supported on the upper part of the grain lifting cylinder 11, and rotary hoppers 17, 17, . Fried grains are processed through openings 21, 21, . . . provided in the shaft cylinder 16 in a plurality of divided chambers whose interior is divided by partition walls 19, 19, . . . It communicates with openings 23, 23, . . . provided at the top of the cylinder 11.

25 is a fixed hopper provided below the rotary hopper 15, with an upper supply port 27 and divided chambers 17, 17, . . .
Opening/closing ports 29, 29,... provided at the bottom of ・
. . . By rotating the rotating hopper 15, they can selectively communicate with each other.

A bag holder 35 is provided below the discharge port 37 at the bottom of the fixed hopper 25, and is used to suspend and support the paddy bag 39.

Reference numeral 41 denotes a floor section provided below the bag holder 35, and the paddy bag 39
This is to hold the bottom of the

43 is a shutter that opens and closes the discharge port 37.

In the above configuration, the grains threshed by the handling drum 7 of the threshing section 3 are conveyed by the conveying spiral 9, sent upward through the grain lifting cylinder 11 by the grain lifting spiral 13, and are sent to the opening 23. ，
21 to divided chambers 17, 17 in the rotating hopper 15...
...is stored within.

When the rotary hopper 15 is rotated so that the opening/closing opening 29 of the appropriate division chamber 17 is aligned with the position of the supply opening 27 of the fixed hopper 25, and the shutter 31 is opened by grasping the handle 33, the grains are removed from the opening/closing opening. From 29, fixed hopper 25
The paddy bag 39 is filled through the discharge port 37. When the grains in this divided chamber 17 are completely discharged, the rotary hopper 15 is rotated to discharge the grains in other divided chambers 17. As described above, the present invention provides a rotary hopper that is horizontally rotatable around the grain lifting cylinder at the upper part of the grain lifting cylinder, and divides the rotating hopper into a plurality of pieces communicating with the grain lifting cylinder. Set up a separate room,
The grain discharge hopper is provided with a fixed hopper below the rotating hopper, and an opening/closing port provided at the bottom of the divided chamber can be selectively communicated with the fixed hopper, increasing the amount of grain stored. It is stored in a position close to the center of the machine, and by storing it in an appropriate divided chamber and selecting the rotational position of the rotating hopper as appropriate, it is possible to maintain equilibrium of the machine and stabilize running. It is something that can be encouraged.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well.
