Description

[Detailed Description of the Invention] The object of the present invention is to ensure that the shutter of the dropper can be switched between operation and non-operation in a reaping and tying machine equipped with a dropper.

In the present invention, the shutter 6 of the dropper can be changed between an operating position and a non-operating position as a dropper, and the cam body 10 linked to the drive wire 11 can be freely rotated independently of the shutter 6. In the working position, the shutter 6 is opened and closed by operating the drive wire 11 via the cam body 10, and when changing the shutter to the non-working position, the cam body 10 is brought into a non-acting state with respect to the shutter 6. It is something.

Figure 1 is a plan view schematically showing the reaping and tying machine.

1 is a traveling mechanism, and shows a general reaping and binding machine in which a dropper 6' consisting of a pedestal 5 and a shutter 6 is provided on the outside of the binding passage 3a of the binding device 3. The shutter 6 is used as a dropper. When in operation, it is rotatable from the solid line position A in Figure 1 to the imaginary line position B, and when inactive, it is in the position shown in Figure 2.

Next, with reference to FIGS. 3 to 5, the shutter drive device, which is the main part of the present invention, will be explained.

The base 6a of the shutter 6 is pivoted 8 to a support plate 7 extending laterally from the binding case, support frame, and other appropriate locations on the machine, and an arm 9 is attached to the upper end of the base 6a.
are welded and integrated with the shutter 6.

The cam body 1 is located between the arm 9 and the support plate 7.
0 loosely fit into the base 6a of the shutter 6, and
0 is rotatable independently with respect to the shutter 6. An end of a drive wire 11 is pivotally attached 12 to one end of the cam body 10, and a cam surface 13 is formed at the other end.

The cam surface 13 is connected to the pin 1 fixed to the arm 9.
When the cam body 10 rotates in the direction of the arrow A, the arm 9 comes into contact with the arm 9 and rotates in the direction of the arrow B.

The other end of the spring 15, one end of which is locked to the pin 14, is attached to the support plate 7 at a position where the arm 9 passes over the fulcrum when rotating from the shutter operating position to the non-operating position.
Alternatively, it is locked to a locking piece 16 that protrudes from a proper position on the body.

In the state where it functions as a dropper, as shown in FIG. 1, the shutter 6 is in the closed position indicated by the solid line opposite to the end of the bundling passage, and collects the bundled waste straw discharged from the bundling passage to collect a predetermined number (for example, two bundles). When accumulating the straw, the cam body 10 is rotated in the direction of arrow A by manual pulling of the drive wire 11, and the shutter 6 is rotated to the open position shown on the imaginary line, and the accumulated waste straw is transferred to the field or to the machine side of the reaping and tying machine. The method of discharging onto the accumulating vessel attached to the side is the same as in the conventional device.

If it is desired to release the bundled waste straw discharged from the bundling passage to the field without functioning as a dropper (without accumulating the bundled waste discharged from the bundling passage), manually move the shutter 6 to the non-operating position as shown in Fig. 2. However, when the shutter 6 is moved to the non-operating position shown in FIG. 2, the cam body 10 does not rotate, so the drive wire 11 remains at the position shown in FIG. .

When the shutter 6 rotates in direction B, when the tip of the arm 9 exceeds the fulcrum crossing position (X-X'), the pin 14 contacts the cam body 10 due to the fulcrum crossing action of the spring 15 [or the shutter 6 The stopper (not shown) is rotated to a position where it comes into contact with a stopper (not shown) provided at an appropriate position, thereby reliably maintaining the dropper non-operating state.

When returning to the dropper operating position, the shutter 6 is manually rotated in the reverse direction B. After passing over the fulcrum, the spring 15 returns to the position shown in FIGS. 1 and 4.

In the present invention, the shutter 6 of the dropper can be freely changed between an operating position and a non-operating position as a dropper, and a cam body 10 that is linked to a drive wire 11 is loosely fitted into the base 6a of the shutter 6. At the operating position of the shutter, the shutter 6 is opened and closed by operating the drive wire 11 via the cam body 10, and when changing the shutter 6 to the non-operating position, the cam Since the body 10 is placed in a non-active state with respect to the shutter, the movement of the drive wire can be shortened compared to the amount of rotation of the shutter to the non-active position, and there are advantages such as no burden such as bending.

Claims (1)

[Scope of utility model registration request] In a reaping and tying machine equipped with a dropper connected to a tying device on the side of the machine, a shutter 6 of the dropper whose base 6a is pivoted at an appropriate position on the machine can be freely changed from an operating position as a drawer to a non-operating position. In addition, a cam body 10 having one end fixed to the end of the drive wire 11 and the other end having a cam surface 13 is provided.
The intermediate portion of the cam body 10 is loosely fitted into the base 6a of the shutter 6, and the cam body 10 is rotatably provided independently of the shutter 6. The shutter is in a non-acting state, and the cam body 1 is in the operating position of the shutter.
In the dropper of a reaping and tying machine, the shutter is opened and closed by locking the shutter with an arm 9 integrated with the shutter and rotating the shutter 6 through a cam body 10 by operating a drive wire 11. Shutter drive device.
