Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a reaper capable of cutting a plurality of strips, which has a fixed grass body in front of a mowing device and a vertically-rotating type forced weeding mechanism.

[Conventional technology]

The vertical turning type forced weeding mechanism is for forcedly combing and weeding the planted culm which has largely fallen down to a standing posture where the horizontal turning type raising device is easy to act, and the fixed weeding mechanism. It is paired with the grass. Therefore, it is sufficient to deploy the same number of compulsory weeding mechanisms as the number of weeds to surely stand up the overlaid grain culms, but the cost of the compulsory weeding mechanism is high, so it is necessary to provide the necessary functions with as few as possible. The higher the practical value, the better.

Therefore, when performing a backward mowing operation with this type of reaper, in order to ensure separation of the overlaid grain culm and the uncut grain culm to be mowed, the weeds at both ends must always have a forced weeding mechanism. It is necessary to deploy in a pair.

As an example of a reaper based on the above circumstances, see
The one disclosed in Japanese Patent Publication No. 7526 is known.

[Problems to be solved by the device]

The above-mentioned prior art is a two-row mowing machine, which is provided with a vertically-rotating type forced weeding mechanism so as to be paired with one of one side end and the center of three weeding bodies. Since the position can be changed so as to be paired with the grass body on the other end side opposite to the one side end, in this reaping machine, by changing the position of the central forced weeding mechanism, the lying posture It enables to cut back and forth in grain culms.

However, in the case of cutting with the central weeding mechanism and the forced weeding mechanism at one side end adjacent to each other, weeding and cutting of uncut grass culms and culms to be cut by the vertical feeding weeding mechanism It can perform both weed cultivating and culm cultivating, but the central forced weeding mechanism is moved to cut the uncut culm and the cut culm in the case of cutting with paired grasses at both ends. However, since the other compulsory weeding mechanism is located on the side of the harvested culm and the side of the already-cut land, weeding of the cultivated grain culm is not performed. The weeding mechanism was not functioning, and there was room for improvement in the work efficiency of the forced weeding mechanism.

In view of the above situation, the present invention is devised so that the forced weeding mechanism always functions during reciprocating mowing work.
Its purpose is to improve its work efficiency.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a mower described above, comprising a plurality of the forced weeding mechanisms smaller than the number of the weeding bodies, and one of the forced weeding mechanisms of one side end. The forced weeding mechanism is disposed at a position corresponding to the weeding body at one end of the aircraft, and the forced weeding mechanism at the opposite end from the forced weeding mechanism at the one side end is at the one side end. It is characterized in that the plurality of forced weeding mechanisms are integrally movable laterally in a state of being arranged at a position corresponding to the weeding body at the opposite end of the weeding body.

Further, the forced weeding mechanism may be provided with an electric drive unit that drives and laterally moves in response to a command from a switch provided in the control unit.

[Action]

According to the configuration of claim 1, in the reciprocating mowing work,
In both the forward and backward directions, it is possible to perform a vertically-running forced weeding mechanism of uncut mowing culms and mowing culms, and a vertically-running forced weeding mechanism of corn cutting culms.

Further, according to the configuration of claim 2, the vertical turning type forced weeding mechanism can be laterally moved while the reaper is in a steering state.

[Effect of device]

Therefore, in the reaper according to claim 1, the vertical turning type forced weeding mechanism is made economically advantageous by reducing the number of grass bodies to less than the number of grass bodies, and it is possible to reciprocally cut a grain culm in a lying posture. Since the situation in which the forced weeding mechanism on one side does not function as in the past does not occur, the working efficiency of this vertically rotating type forced weeding mechanism is improved, and by doing so, the grain stems can be cut more reliably and smoothly. As a result, the work efficiency of the reaper as a whole could be improved.

In addition to the effect of claim 1, in the reaper of claim 2, the vertically-rotating type forced weeding mechanism can be easily and conveniently laterally moved, and the operation is maintained as a reaper. There is an advantage that you can do it as it is.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings in the case of being applied to a combine.

As shown in FIG. 3, in a combine in which the cutting unit (B) is configured to be movable up and down with respect to the machine (A) equipped with the threshing device (1), the cutting unit (B) is as follows. Constitute.

That is, as shown in FIG. 2, in the front part of the hair clipper-type cutting device (2), a lateral-rotating-type raising device (3) for raising three rows of planting stem culms rearward and upward is provided. The tips of the claws (3a) are arranged side by side in the left-right lateral direction in a state of being opposed to each other, and between the juxtaposed raising device (3) and the threshing device (1), the stalk culm is gradually fallen sideways. The vertical transfer device (5) for supplying and feeding to the threshing feed chain (4) is installed, and the juxtaposed pulling device (3) is installed from the cutting transmission case (6) immediately after the cutting device (2). ) And the supporting rods (8) of the grass bodies (7) are extended forward through the lateral outer side of the juxtaposed pulling device (3), respectively.
Also, the locking claws (9a) and (9a) are provided between the grass bodies (7) ... and the juxtaposed pulling devices (3) and (3) from the lower front to the upper rear along the traveling direction of the fuselage.
