Description

DETAILED DESCRIPTION OF THE INVENTION Zero starter #4 has an internal granulation conveyance screw horizontally or almost horizontally installed in the threshing grain tank, and a thrower set lifting device bJt for the grains from this screw is placed at the end of the screw. It relates to a grain conveying device for a combine that extends from the capital and is operatively connected to an n-age screw or a transmission shaft installed in the cylindrical shaft of this screw.

In the above-mentioned grain conveying device, the lifting device can be switched between a storage position in which the lifting device is laid down in a state substantially along the longitudinal direction or lateral direction of the machine body, and a usage position in which it extends upward and outward from the machine body. However, since both rotations 1F [with the same horizontal axis axis and rotation 1# part around the axis of the thrower cylinder] were provided, it took a lot of effort to change the figure/#. In addition to this, the structure of the lifting device becomes complicated because the thrower cylinder must be divided into a plurality of cylinder parts.

The object of the present invention is to provide a device that can be changed to both positions (9), so that the changeover can be performed easily and easily, and furthermore, the grain from the screw to the thrower caused by this can be easily changed. The purpose is to make it possible to easily solve grain supply problems with a structure.

The characteristic structure of the present invention is that in the above-mentioned fall grain conveying device of the combine harvester, the base end of the lifting device is inclined with respect to the horizontal plane, and the lower side of the machine body is located on the outside of the machine body.
The supporting member of the thrower rotation support shaft is attached to be swingable around the shaft center and formed in a shape that guides the grains from the delivery screw to the lower end side of the thrower above the rotation support shaft. Niashi, its action and effects are as follows.

In other words, by simply turning the lifting device t at one point, it will align with the longitudinal direction or lateral force of the aircraft in the inverted position, and the tip side will move away from the aircraft in the upright position. It becomes an island. Therefore, while the grains can be lifted and transported to a predetermined position and stored in a safe state during travel, switching from either the storage position or the use position to the other is easy by simply shaking and twisting around the l-axis. In addition to being able to
The structure was made easy to configure.

In this case, the upper end side of the thrower will be located on the side of the carry-out screw, but the support member will guide the grains from the carry-out screw to drop to the lower end side of the thrower so that it will be difficult for them to flow into the thrower upper end side. Therefore, it is possible to suppress an increase in the number of grains supplied to the downward rotation side of the thrower and the terminal end of the upward rotation side, and to minimize the occurrence of toggle such as a decrease in the throwing action force of the thrower. The structure can be simplified because the supporting member can also be used as a supporting member.

Embodiments of the present invention will be described below based on the drawings.

As shown in Figs. 1 and 2, the planted culm is scraped into the harvesting device (2) by the rotary reel fl) and harvested, and the reaped culm is transferred to the rotating body (3) and the conveyor ( 4m) , (

dJ section (7), a threshing and sorting section (8) for supplying the entire cut husk from the pretreatment section to the handling room for threshing and sorting the threshed product into whole grains and dust, and a threshing grain tank ( 9) and a grain photographing device (lO) for taking out and transporting grains from this tank (9), the front part of the crawler type traveling machine has a vertical swing operation using a cylinder (U). They can be freely connected to form a combine harvester.

To configure the grain photographing device αO), as shown in FIG. 8, a screw Ct'4 is installed at the bottom of the tank (9).
is installed horizontally or almost horizontally, and one end of the screw sleeve sleeve (12a) is connected to the belt tension clutch α.
It is linked to the engine (+5) through the barrel and intermediate shaft (+4) 41 to enable the drive of the screw (+2), and the slotted lifting device H is extended from the conveying end of the screw (1'4). At the same time, the rotation support shaft (16b)'iz of the thrower (16m), the bevel gear mechanism (+7),
A power transmission shaft (1 m) and a belt tension clutch (I@i
The thrower (16a
), the grains in the tank are carried out to one side of the fuselage by the screw 02), and the thrower (
By the releasing action of 16a), it is lifted along the sys lower tube (16c) and discharged from the rotary discharge tube (lad).

The base end of the thrower cylinder (16c) is attached to a bracket extending δ from the tank (9), and a wooden shaft center (P) located on the lower side of the fuselage is located on the lateral outer side and rear side of the fuselage. The lifting device (+6)'t is attached so that it can be rotated freely around the tank, and extends rearward from the tank (9) almost along the longitudinal direction of the aircraft, and is located near the top of the prime mover (7). It is designed to be able to swing between a reclining storage position in which the tank (9) is lowered, and a standing position in which it extends upward from the tank (9) toward the outside of the fuselage.

1] Extend the rotary member η of the Qie rotary shaft (1ab) from the take-out screw (12) side in the thrower storage section of the thrower cylinder (16c), and
b) is disposed on the upper side and has a curved side surface (21a) which guides the grains from the carry-out screw to the lower end side of the thrower (16a). Care is taken to prevent grains from flowing into the upper end of the thrower (16a) by the support section. 4 In the above implementation configuration, the lifting device pet is connected to the yA moving part (
7), and because the base end of the lifting device 0@10 is located at a lower level than the upper edge of the driving part (7), the lifting device 0 is not easily moved when stored. Since the position is slightly inclined when viewed from the side, the rotation axis (P) is tilted so that the lifting device follows the longitudinal direction of the aircraft even when the slope is steep. (If the device H can be placed horizontally, the axis of rotation (P) may be vertical when viewed from the side.)

Furthermore, the present invention can also be applied to the case where the screw 02) is arranged in the longitudinal direction of the aircraft body. In short, the rotation axis (P) is inclined with respect to the horizontal direction and All you have to do is set it to the axis located on the outside of the fuselage.

Further, the present invention provides a structure in which the thrower rotation support shaft (tab) is interlocked and connected to the screw (12) so that the thrower (16a) is driven and stopped integrally with the screw α. can also be applied.
