Description

[Detailed Description of the Invention] This invention relates to a cylinder cutter for cutting threshed waste straw, etc., which makes it safer for workers by making it difficult for workers to insert their hands into the cutting part through the opening of the cylinder. It is.

If the ejector tube that protrudes sideways from the machine frame cover that houses the cylinder cutter is made longer, even if the operator inserts his/her hand into the machine frame's inner cavity through the opening of the ejector tube, the cutting part where the rotary blade is rotating can be easily removed. However, when cutting a heavy object such as wet waste straw, the distance that the cut object jumps out becomes shorter and it may get stuck in the ejection tube. In addition, if this cylinder cutter is attached to the rear of the combine machine, the long ejection tube increases the overall length of the machine, so it gets in the way when not in use and is inconvenient when transporting the combine by car. be.

This invention is intended to solve the above-mentioned disadvantages, and is constructed as follows. That is, an opening/closing lid 7 with left and right side walls that covers and opens and closes the opening from above is provided at the tip opening of the ejection tube 5 protruding from the machine frame cover 4 in which the cylinder cutter 3 is installed. A drawer lid 6 is provided on the bottom side of the ejection tube 5 to cover the bottom surface and to form a lower edge of the opening with its tip edge so as to be freely removable and removable in the projecting direction of the ejection cylinder 5.
The discharge tube of the cylinder cutter is configured such that the distance from the inner cavity of the machine frame cover 4 to the lower edge of the opening of the discharge tube 5 can be adjusted.

The present invention achieves the following technical effects through the above configuration. That is, when cutting a light object such as dry waste straw with the cylinder cutter 3, the opening/closing lid 7 should be opened wide and the drawer lid 6 should be pulled out to the maximum extent.
Even if the tip opening of the cylinder cutter 3 is moved away from the cylinder cutter 3 to make it safe, the cut object will not pass through the discharge cylinder 5 and be discharged from the opening and cause clogging.
In addition, when cutting a heavy object such as damp waste straw, the ejector tube 5 in the above state does not allow the cut object to jump out easily, and the cut object falls onto the bottom of the ejector tube 5, that is, onto the drawer 6. It gets stuck and causes a blockage. Therefore,
By pushing in the drawer lid 6 appropriately to shorten the distance from the inner cavity of the machine frame cover 4 to the lower edge of the opening of the ejecting cylinder 5, and appropriately covering the opening with the opening/closing lid 7, a substantial ejection opening for the cut material can be formed. If the cut material is moved toward the bottom side of the ejection cylinder 5, clogging of the ejection cylinder 5 with cut objects can be prevented. At this time, since the discharge port is opened on the bottom side of the discharge tube 5, it is difficult to reach the cylinder cutter 3 from the discharge port, which is safe.

In this way, even when the object to be cut is so heavy that it is difficult to jump out from the inner cavity of the machine frame cover 4, the ejection tube 5
Discharging is possible by bringing the lower edge of the opening closer to the inner cavity of the machine frame cover 4. In that case,
By pointing the opening/closing lid 7 on the drawer lid 6 downward, it is safe to prevent the operator's hands etc. from entering the inner cavity of the machine frame cover 4 through the opening of the ejection cylinder 5.

In addition, if the opening/closing lid 7 and the drawer lid 6 are connected in such a way that the opening/closing lid 7 and the drawer lid 6 can be moved in and out as the opening/closing lid 7 is opened/closed, the opening/closing lid 7 and the drawer lid 6 can be adjusted at the same time, making the operation easy. At the same time, it can be used in a safe manner.

Next, an embodiment of this invention will be explained with drawings.
Reference numeral 1 denotes a straw discharge port of the threshing section of the combine. A pair of front and rear supply rolls 2, 2 and a lower cylinder cutter 3 are covered with a machine frame cover 4 and attached below the straw discharge port 1. A discharge tube 5 is provided to protrude rearward from a machine frame cover 4.

6 is a drawer lid provided on the bottom side of the ejection cylinder 5;
It can be moved in and out of the ejection cylinder 5 in the direction of the cylinder. An opening/closing lid 7 is hinged to the upper edge of the opening at the tip of the discharge cylinder 5, and the left and right side walls of the opening/closing lid 7 and the left and right side walls of the drawer lid 6 are connected by a connecting rod 8. Therefore, the drawer lid 6 moves in and out as the opening/closing lid 7 is opened and closed. Then, a set screw 9 is inserted into the overlapping portion of the elongated hole 6a formed in the side wall of the drawer lid 6 and the arc-shaped hole 7a formed in the side wall of the opening/closing lid 7, so that the opening degree of the opening/closing lid 7 can be maintained appropriately. Make it.

When cutting dry waste straw, if the opening/closing lid 7 is opened to the maximum, the drawer lid 6 is also pulled out by the connecting rod 8, and the opening of the discharge tube 5 is moved away from the cylinder cutter 3, making it safe. In addition, when cutting wet waste straw, if the opening/closing lid 7 is opened appropriately, the drawer lid 6 will also be pulled out briefly by the connecting rod 8, and the discharge port will be formed near the bottom of the discharge tube 5, allowing the cylinder cutter to be opened. As you approach Tar 3, the passage is curved, making it difficult for your hands to get in, making it safe.

When the cylinder cutter 3 is not in use, if the opening/closing lid 7 is closed, the drawer lid 6 is automatically retracted and the total length of the ejection cylinder 5 can be shortened.

In this manner, in the embodiment described above, the drawer 6 is also moved in and out by opening and closing the opening/closing lid 7, so that the operation is easy.
