Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a state in which, on the outside of a side plate forming a handling opening, a feed chain and a clamping rail opposite to its conveying surface are urged to move elastically toward the feed chain. The present invention relates to a threshing device in which a rail stand supporting the grains is disposed in a vertical positional relationship with the rail stand being located on the upper side.

In such conventional threshing equipment, a rail stand was constructed across the front side wall of the handling room and the rear side wall of the handling room, but when using this, due to the structure of the equipment, the rear side wall of the handling room was Since the strength is weaker than the rear machine wall, which is located on the lower side in the gripping and conveying direction than the front side wall of the room and the rear side wall of the handling room, the rear side wall of the handling room is made strong to ensure the mounting strength of the rail stand. In order to achieve this, it is necessary to rely on the reinforcing effect of a reinforcing frame constructed across the front side wall of the handling compartment, the rear side wall of the handling compartment, and the rear machine wall, and therefore, the reinforcing frame must be a large and heavy frame. There were some unavoidable flaws.

In addition, in the conventional threshing equipment described above, when the conveying grain culm becomes clogged between the feed chain and the clamping rail, the clamping rail is generally separated from the feed chain to remove the clogged grain culm. However, for example, as disclosed in Utility Model Application Publication No. 52-95862, a clamping rail (guide)
Although it is known that a rail stand (frame) connected to a clamping rail is swingably pivoted so that the clamping rail (guide) can be separated from the feed chain, Since there was no structure to securely support the grain in a separated state, it was necessary to manually support the clamping rail or rail stand when removing the clogged grain culm. There is the difficulty of having to remove the clogged grain culm with one hand while supporting the rail extension. This has the disadvantage that you cannot work independently, and that there is a risk of danger if you carelessly remove your hands.

In view of the above, an object of the present invention is to provide a threshing device that can strengthen the handling chamber while reducing the size and weight of the reinforcing frame, and that allows easy removal of the clogged grain culm.

In the threshing device according to the present invention, the rail stand is connected to the front side wall of the handling chamber, the rear side wall of the handling chamber, and the rear machine wall located on the downstream side in the direction of clamping and conveyance with respect to the rear side wall. The rail base is installed across the front side wall and the rear aircraft wall in a posture along the reinforcing frame that has been installed over the area, and the rail base is pivoted to the reinforcing frame at its rear end, and the rail base is pivoted to the reinforcing frame at its rear end. The rail stand is configured to be vertically swingable, and further, the rail stand is in a transporting posture position in which grain culms are pinched and conveyed by the feed chain and the clamping rail, and the clamping rail is spaced apart from the feed chain. A feature of the present invention is that rail attitude changing means capable of changing and holding the rail attitude are provided at two positions: a non-working attitude position and a non-working attitude position.

In other words, since the rail stand is also installed along the reinforcing frame, spanning the front wall of the handling room, the rear side wall of the handling room, and the rear machine wall, the installation strength of the rail stand is sufficient. Not only that, but the rail stand can also act as a reinforcing frame that connects the front side panel of the handling room and the rear machine wall in the same way as a reinforcing frame, reducing the burden on the reinforcing frame. Although it is strongly installed, there is no need to make the reinforcing frame particularly large or heavy.

In addition, the rail stand can be set in two positions: a conveyance working position where the grain culms are held and conveyed by the feed chain and the holding rail, and a non-working position where the holding rail is separated from the feed chain. Since the rail position changing means for changing and holding the rail is provided, when a jam in the clamping conveyance occurs, it is possible to change the position of the rail stand to a state where the clamping rail is separated from the feed chain and to hold the rail. By being able to do this, there is no need to manually hold the rail stand, making it possible to safely and easily remove clogged grain culms.

Hereinafter, an embodiment of the present invention will be described based on the drawings. A feed chain 3 and a clamping rail 4 opposite to the conveying surface 3A of the feed chain 3 are installed on the outside of the side plate 2 forming the handling opening 1. A rail stand 6 that supports the surface 3A so as to be movable toward and away from the surface 3A and biased to move in the approaching direction via a spring 5 is arranged in a vertical positional relationship with the rail stand 6 located on the upper side. In addition, a round pipe-shaped reinforcement is provided between the front wall 7 and the rear wall 8 of the handling room A equipped with the handling trunk a, and the rear machine wall 9 located on the lower side in the direction of clamping and conveyance with respect to the rear wall 8 of the handling room. In a threshing device in which a frame 10 is constructed along the upper side of the side plate 2 and a top plate 11 is pivotally connected to the reinforcing frame 10 so as to be able to swing open and close, the rail stand 6 is attached to the reinforcing frame 10. It is constructed across the front side wall 7 and the rear machine wall 9 in a posture along the handling port 1. Note that the rear end of the rail stand 6 is not directly connected to the rear machine wall 9, but is connected near the position where the reinforcing frame 10 is connected to the rear machine wall 9.

In addition, the rail stand 6 has its rear end at a fulcrum R.
By vertically swinging, the clamping rail 4 is brought close to the transporting surface 3A and the grain culm is clamped and transported to a transporting position, and the clamping rail 4 is moved upwardly away from the transporting surface 3A to a position in which the clamping is released. It is configured such that the posture can be switched between a non-working posture and a non-working posture.

Further, the rail stand 6 is configured such that the upper end bent piece 6a of the frame 6A, which is connected to the free swinging end, is placed on the reinforcing frame mounting bracket 12 fixed to the front wall 7. By connecting the piece 6a to the bracket 12 via a bolt with a knob 13, it is configured to be fixed in the above-mentioned working position, and the above-mentioned lifting frame 6A is provided with the above-mentioned rail stand 6 in a state that allows the position of the rail base 6 to be changed. A groove 15 formed in a plate material 14 connected to the side plate 2 is engaged to restrict the distance movement of the rail stand 6 with respect to the side plate 2 in both positions, and to prevent the rail stand 6 in the non-operating position from falling. Rod-shaped member 1
6 is fixed.

Further, the swinging free end of the top plate 11 is elastically engaged with a pipe frame 17 disposed opposite to the reinforcing frame 10 as the top plate 11 swings closed. An elastic engagement piece 18 that elastically maintains the closed position is attached via a bolt 19, and the bolt 19 causes the elastic engagement piece 18 to connect to the pipe frame 17 by bringing its tip into contact with the pipe frame 17. This is to regulate the depth of engagement.

In the figure, reference numeral 20 denotes a rail stand 6 that covers the top and side surfaces of the rail stand 6 and the sides of the clamping rail 4.
This is a safety cover attached to the safety cover, and the swinging free end portion of the upper cover portion is connected to the knob-equipped bolt 13 for connecting the upper end bent piece 6a and the connecting bracket 12.
They are attached in a co-tightened state via the . 21
is a waste straw transport device that transports threshed grain culms (discarded straw) to the rear of the rear machine wall 9.

In addition, a reinforcing frame 10 is connected to the rear machine wall 9.
