Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cleaning port opening/closing device for a grain lifting and conveying device in a combine harvester or the like.

Prior Art and Problems In a grain lifting and conveying device that lifts and conveys grains from a horizontal screw conveyor of a threshing device by a vertical screw conveyor, a horizontal screw that covers the horizontal screw conveyor in a portion protruding from the side wall of the threshing device is used. A cleaning port is opened across the U-case and the vertical screw case that covers the vertical screw conveyor, and this cleaning port is equipped with a lid that can be opened and closed by swinging to easily remove clogged grains from the cleaning port. Those constructed in such a way that they can be removed are known. By the way, as a means for opening and closing such a cleaning port,
Conventionally, the opening/closing operation mechanism was provided on the outside of the vertical screw case, which not only obstructed the paddy bag placed on the pedestal, but also caused problems in replacing the paddy bag. Opening and closing operations are also cumbersome.
It was troublesome.

Means for Solving the Problem The technical means according to the present invention is a grain lifting and conveying device configured to lift and convey grains from a horizontal screw conveyor 1 of a threshing device by a vertical screw conveyor 2. At the same time, a cleaning port 6 is opened across the horizontal screw case 3 that covers the horizontal screw conveyor 1 and the vertical screw case 4 that covers the vertical screw conveyor 2 in the portion protruding from the side wall 5 of the threshing device. , an opening/closing lid 7 that can swing open and close around a fulcrum P is provided, and between the side wall 5 of the threshing device and the vertical screw case 4 is a support shaft 8 that is pivotally supported for reciprocating rotation. An interlocking rod 9 that pivots to open and close the opening/closing lid 7, and an operating lever 11 that pivots the support shaft 8 back and forth through a plate spring 10.
It is characterized by being provided with an operation interlocking mechanism 12 consisting of the following.

Effects of the invention Therefore, according to the invention, since the opening/closing operation interlocking mechanism of the opening/closing lid is provided by utilizing the space between the side wall of the thresher and the vertical screw case, the operating lever etc. It is possible to easily replace the bag without causing any hindrance, and the opening and closing operations of the cleaning opening can also be easily performed, making it possible to solve the conventional problems.

Furthermore, although it has a simple opening/closing mechanism, it also has the advantage of being able to be opened and closed with a single touch.

Embodiment An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a horizontal screw conveyor that is installed on an internal shaft in the first receiving gutter of the threshing machine.This horizontal screw conveyor 1 transports grains to the outside of the machine, and a vertical screw conveyor 2 stands up from its terminal end. It is constructed so that it can be lifted and transported by.

The horizontal screw conveyor 1 has an outer end projecting from a side wall 5 of the threshing device, and the projecting portion is internally mounted on a horizontal screw case 3 which is fixedly attached to the side wall.

The lower end of the vertical screw conveyor 2 is mounted on an internal shaft in a vertical screw case 4 that is integrally constructed with the horizontal screw case 3, and another The vertical screw case is connected and fixed. The horizontal screw case 3 and the vertical screw case 4 are provided with a cleaning opening 6 formed in a notch across the outer surfaces of both, and an opening/closing lid 7 is provided in the cleaning opening 6 by swinging to open/close around a fulcrum P. possible.

In the space between the side wall 5 of the threshing device and the vertical screw case 4, there is a vertical support shaft 8 that is rotatably supported on the side of the vertical screw case 4 and a reciprocating rotation of the support shaft 8. an interlocking rod 9 that swings open and close the opening/closing lid 7 around a fulcrum P by movement, and the supporting shaft 8.
An operation interlocking mechanism 12 is provided, which includes an operation lever 11 that is connected to the operation lever 11 for reciprocating rotation operation via a leaf spring 10.

Reference numeral 13 denotes a locking tool, which is fixed to the vertical screw case 4 so as to be locked by operating the operating lever 11 of the opening/closing lid 7 in the closing direction against the leaf spring 10.

Reference numeral 14 denotes a bag holder, which is installed outside the vertical screw case 4 and configured to receive the bottom of the bag that receives and stores the grains discharged from the upper end outlet of the case 4.

The operating lever 11 is swingable about the support shaft 8, and is configured to be swingable within the space between the threshing device side wall 5 and the outer surface of the vertical screw case 4. ,
It is arranged so that it does not protrude onto the bag holder 14 installed outside the vertical screw case 4 and interfere with the bag.
