Description

[Detailed Description of the Invention] The present invention relates to a clipper type reaping device used for example in combine harvesters and binders. The sliding blade 3 is attached with a knife clip 10, and
A free end of a swinging arm 5, which is pivotally supported by the fixed member 7 so as to be swingable in the longitudinal direction of the fixed blade 1, is engaged with a bracket 4 fixed to the sliding blade 3, and the swinging arm Reference numeral 5 relates to a clipper type reaping device which is operatively connected to a crank type drive device 6 fixed to the fixed member 7.

As this type of clipper type reaping device, the one shown in FIG. 4 has been known.

The clipper type reaping device is capable of reaping a wide range at once by reciprocating the sliding blade 3 over substantially the entire length of the fixed blade 1 in the longitudinal direction. Stems and culms can be cut with good sharpness by the relative movement between the blade and the fixed blade 1. However, if mud gets stuck between the sliding blade 3 and the fixed blade 1 or if the edge of the sliding blade 3 is worn out, cutting becomes difficult, so the sliding blade 3
It is necessary to remove and adjust and repair. At this time, conventionally the knife clip 10 is removed and the sliding blade 3
The working procedure is to separate and remove the sliding blade 3 by predetermined length, and this working procedure has the drawback that it requires a lot of effort to reinstall the sliding blade 3.

The present invention aims to eliminate such drawbacks.

In order to achieve this purpose, the clipper type reaping device of the present invention has a bracket fixed to the sliding blade and a free end of the swinging arm, a locking pin is fixed to one end, and a locking pin is fixed to the other end of the swinging arm. The swinging arm and the crank type drive device are connected by an engagement structure having an open-end recess that allows the pin to detach when the swinging arm is swinged beyond the range of swinging during reaping, and the swinging arm and the crank type drive device are
The blades are connected via a telescopically fixed or removable connector, and the sliding blade is attached to the fixed blade so that it can be freely pulled out in the longitudinal direction. With this configuration, the swinging arm can be displaced beyond the sliding range during reaping by either detaching the coupling device or expanding and contracting it, and in this case, one end of the sliding blade is at the end of the fixed blade. In addition, the swing arm and the sliding blade are disengaged from each other. As a result, the sliding blade can be pulled out with one end, allowing the knife clip to be released or removed.
The sliding blade can now be easily removed from the fixed member without dividing the sliding blade. On the other hand, when attaching the sliding blade, it is only necessary to slide it between the knife clip and the fixed blade and set the connector in a predetermined state, making the work easier. Furthermore, when attaching and detaching the sliding blade, the fact that one end thereof protrudes beyond the fixed blade has the advantage that the sliding blade can be attached and detached without touching the dangerous edge of the blade.

Next, an embodiment of the present invention will be described.

In this embodiment, a fixed blade 1, a knife clip 10, a sliding blade 3, a bracket 4, a swinging arm 5,
The structures of the crank type drive device 6 and the fixed member (reaping frame) 7 are the same as those of the conventional device shown in FIG. 4, so detailed explanations thereof will be omitted.

As shown in FIG. 1, the fixed blade 1 is placed and fixed on an L-shaped frame 8 that integrally extends from the fixed member 7, and is placed and fixed on the rear part of the fixed blade 1. The rear end of a knife clip 10 is fixed to the horizontally long rail 9, and the knife clip 10 presses down the sliding blade 3 and a fixed sliding rail 11 at the rear thereof. And as shown in Figure 2,
The bracket 4 is fixed near the end of the sliding blade 3 at a position outside the knife clip 10, so that the bracket 4 is not jammed by the knife clip 10 when trying to pull out the sliding blade 3. It is designed so that it can be pulled out upwardly on the drawing in FIG. Further, the bracket 4 is formed with a recess 12 that is open at one end toward the rear, and a pin 13 fixed to the free end of the swing arm 5 is engaged with the recess 12 to form an engagement structure 14. It is configured. The other free end of the swing arm 5 is operatively connected to the crank type drive device 6 via a connector 15 that can be extended and fixed. The connector 1
5 is divided into two parts that are slidably fitted into each other in the middle, and two through holes 16 and 16' are formed in one side in the sliding direction, and one through hole 17 is formed in the other side. are formed, and both through holes 16, 17 or 1
By selecting the penetration of the pin 18 through the pins 6' and 17, the pin 18 can be expanded and contracted, and the length is set so that the pin 13 can be pulled out from the recess 12 in the contracted state. Although not related to the gist of the present invention, a weeding tool 19 is fixed to the front end of the fixing member 7, and inside this weeding tool 19 are shown
As shown in (b), a cutting blade 20 is housed, and a slit 21 is formed in the front face of the weeding tool 19 facing the cutting blade 20 to move the weeding tool 19 in and out. A release wire 22 is provided that allows the camera to be moved in and out by remote control.

In the embodiment described above, it is possible to change the configuration target by one or more of the following combinations.

The recess 12 is formed in the swing arm 5 in a shape that opens forward, and the pin 13 is fixed to the bracket 4.

The connecting tool 15 is made into a rod that does not extend or contract, and the connecting tool 15 is connected to the swinging arm 5 by a pin that can be freely inserted and removed, and the swinging arm 5 and the connecting tool 15 are connected detachably.

To be used as a mower for mowing grass and lawns.
