CONSTITUTION:In this grain conveyor, a spiral cylinder 6 involving a conveying spiral for conveying grains in the inside is equipped with an opening 7 for cleaning and this opening 7 for cleaning is provided with an opening and closing cover 8 capable of shaking, opening and closing around a support shaft 15. The opening and closing cover 8 is linked through a working member 18 composed of a spring material to an operating lever 19 for shaking, opening and closing the opening and closing cover. The opening and closing cover 8 is also designed so that the shaking edge side thereof may be pressed and energized according to an actuation of the working member 18 toward the closing side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a cleaning opening for a spiral tube for carrying grains, a swingable opening / closing lid for opening / closing the opening, and an operation for opening / closing the lid. The present invention relates to a grain conveying device provided with a lever.

[0002]

2. Description of the Related Art Conventionally, as this type of grain conveying device,
The operation member for operating the opening / closing lid toward the closing side and the spring member for biasing the opening / closing lid toward the closing side by the operation of the operation lever are separately configured. (For example, the actual exploitation Sho 57-117963
(See issue)

[0003]

According to the prior art, the operation interlocking mechanism for opening / closing the opening / closing lid is complicated and requires a large dedicated space. Moreover, the spring member is attached because it has a single structure. There was a problem that the opening and closing lid could not be securely supported and fixed due to unstable power. The present invention has the following technical means for the purpose of solving the above problems.

[0004]

That is, according to the present invention, a cleaning opening 7 is provided in a spiral cylinder 6 in which a conveying spiral 5 for conveying grains is installed, and the cleaning opening 7 has a fulcrum shaft 1
5 is a grain transporting device provided with an opening / closing lid 8 which can be freely opened and closed by swinging, the operating member comprising a spring material for the opening / closing lid 8 and an operating lever 19 for swinging and opening the opening / closing lid. 1
8, and is configured to press and urge the swing end side of the opening / closing lid 8 toward the closing side due to the closing side operation of the operating member 18. is there.

[0005]

By operating the operating lever, the opening / closing lid can be largely swung open / closed via the actuating member. Moreover, the swinging end side of the opening / closing lid can be opened only when the operating member itself is operating on the closing side of the opening / closing lid. Since the pressing force is applied, the opening / closing lid can be supported and fixed in a stable and reliable manner as compared with the case where another spring member is applied. In addition, since the actuating member also serves as the spring member, the structure is simple and the space for exclusive use thereof is small.

[0006]

As a result, the open / close lid can be stably and reliably supported and fixed without requiring a large exclusive space even though it has a simple structure.

EXAMPLES Examples of the present invention will be described below. The side-feed spiral gutter is provided below the grain selection device of the threshing machine, and is configured to be capable of receiving grains falling from the upper side and laterally conveying the grains outside the machine by rotating the side-feed spiral 1. One end extends outward from the machine body to form a lateral feed spiral cylinder 2. The lateral feed spiral 1 extends from the lateral feed spiral gutter and is positioned inside the lateral feed spiral tube 2. 9 is the axis of this lateral feed spiral 1,
One end is supported by the outer end of the lateral feed spiral cylinder 2.

The cleaning opening 3 is provided at the lower side of the lateral feed spiral cylinder 2, and an opening / closing lid 4 is provided so as to be swingable and openable around a swing fulcrum shaft (hinge 10). The lifting helix cylinder 6 communicates with the terminal end of the transverse feed helix cylinder 2 through a communication port 11, and the lifting and conveying helix 5 is internally supported by a shaft 12 so as to stand upright and a discharge port is provided at the upper end. It can be exposed to the grain tank or bag mouth. The lower end of the lifting helix shaft 12 bears on the bottom of the lifting helix cylinder 6 and is geared with the shaft 13, and a chain is provided between the sprocket of the shaft 13 and the sprocket at the end of the transverse feed helix shaft 9. It is configured to rotate in conjunction with 14.

The cleaning opening 7 is opened at the lower end of the lifting helix cylinder 6 at the outer periphery of the lower rotation zone of the conveying spiral 5, and the opening / closing lid 8 is swung open / close around the swing fulcrum shaft 15. It is provided freely. The bracket 16 to which the opening / closing lid 8 is attached is integrated with the lateral feed spiral tube 2 attached to the outer end of the machine body 17, and holds and holds the spiral tube 6 on the machine body 17.
A leaf spring 18 is fixed to the opening / closing lid 8 as an operating member, and an operation lever 19 is attached to the tip of the leaf spring 18 so as to be rotatable only in the lateral direction, and an engaging portion 20 provided on the bracket 16 is provided. The operation lever 19 is engaged with the opening lever 8 in the closing direction by the elastic force of the leaf spring 18. Further, between the outside of the opening / closing lid 8 and the outside of the opening / closing lid 4, both ends of a coil spring 21 having an intermediate portion wound as an operating member are engaged with each other to open / close the opening / closing lid 8.
On the other hand, the opening / closing lid 4 is provided to elastically spring in the closing direction, and the elastic force of the leaf spring 18 is made stronger than the elastic force of the coil spring 21.

The grain processed in the machine body 17 is received by the lateral feed spiral gutter, is taken out to the lateral feed spiral tube 2 by the rotation of the lateral feed spiral 1, and is passed through the communication port 11 to lift the helical head tube 6. Is lifted and transported. At this time, operation lever-1
9 is in the position shown by the solid line in FIG. 1, and is engaged with the engaging portion 20 so that the opening / closing lid 8 elastically closes the opening 7 by the operating member (leaf spring 18). Coil spring 2
The opening / closing lid 4 is repelled via 1) to close the opening 3 so that the conveyed grains are not leaked from the openings 3 and 7.

When opening the openings 3 and 7, the operation lever 19
When the engaging member 20 is disengaged, the operating member 18 is loosened and the opening / closing lid 8
Rotates about the swing fulcrum shaft 15 to open the opening 7, and further opens the opening / closing lid 8 to loosen the operating member (winding spring 21) to open the opening / closing lid 4 about the swing fulcrum shaft 10. By moving them, the residual particles, dust, and the like in the lateral feed spiral cylinder 2 and the lower end of the lifting spiral cylinder 6 are removed from these openings 3 and 7 for cleaning.
