The present invention relates to a paddy bag receiving device of a paddy receiving section in a self-propelled threshing machine, in which a paddy bar and a paddy tray are arranged vertically to provide a paddy receiving section for storing grains from the threshing machine.

(B) Conventional technology As described above, in the self-propelled thresher configured by mounting the threshing machine and the engine on the traveling chassis and providing the steering section with handle and the paddy receiving section on the rear side of the engine, As the ones described in Japanese Utility Model Publication No. 55-39956,
Like the one configured to collect those falling on the paddle when exchanging the paddy bag when the paddy bag that stores the grains from the threshing machine is full, as in Japanese Utility Model Publication No. 49-1811 A foot pedal is provided on the pedestal on the traveling chassis, and when the foot pedal is stepped on, a part of the pedestal is moved up as a paddle paddle to raise the paddy bag and replace the full paddy bag. There are things that try to make it easier.

(C) Problem to be Solved by the Invention Although the present invention is intended to facilitate the replacement of a full paddy bag like the latter one, the foot pad for moving the paddle pedestal is moved upward. In addition to making it easier to depress the pedal, the full paddy bag can be easily removed from the paddle bar, making it easier to replace the paddy bag and also the grain from the threshing machine. It was devised because it helps to fill it up.

(D) Means for Solving the Problems The present invention makes it easier to replace the paddy bag as described above and helps to fill the grain in the paddy bag with the grain on the traveling chassis. Equipped with a thresher on the front side and an engine on the back side,
In a self-propelled threshing machine configured by providing a steering section with a handle on the rear side of the engine, and a paddy receiving section for arranging the grain from the threshing machine by arranging the paddy bar and the paddy stand vertically. A support pipe is erected at the rear ends of the left and right frame bases, and is freely rotatable between the paddy pedestal mounted on the support arm that can be moved upward using the support pipes as a fulcrum and the support plate hung from the left and right frame bases A foot pedal is welded to the extension part of the arm extending rearward from the base member that is horizontally mounted on the pivot shaft pipe located below the support pipe and passes through the underside of the paddle cradle. Then, the operating member and the engaging recess for engaging the operating member are provided at the opposing positions of the base member and the base portion of the supporting arm.

(E) Action According to this configuration, the grains that have been supplied to the threshing machine and obtained as a result of the threshing process are converted into single grains, and the grains are conveyed backward and suspended by the paddle and also by the paddle stand. Threshing work is carried out while it is dropped into a supported paddy bag and stored.

Then, when the grain in the paddy bag is full, the filled paddy bag is replaced with an empty paddy bag. When the foot pedal located is stepped on, the paddle pedestal moves up slightly by the depression operation and lifts the filled paddy bag, so that the paddy pedestal holds the upward movement state. Therefore, the paddy bag is removed from the paddy bar and replaced with an empty paddy bag. Also, when the grain is transported backward from the thresher and stored in the paddy bag, and when the paddy bag is almost full, the grains falling into the paddy bag stagnate and the paddy bag is never filled. At this time, if the foot pedal is depressed about 2 to 3 times to move the paddle pedestal up and down, the vibration causes the stagnant grains to spread around the inside of the paddy bag and the paddy bag becomes full.
