Example Mounting slide type combine and its example Mounting fixture

The present invention relates to a structure of a preloaded slide type combine and a structure for fixing the slide of the preloaded part in a small combine, in which the cut-out portion can be shifted left and right.

Conventionally, a combine having a pretreatment portion slidable in a left and right direction, and a pretreatment portion having a grain removing pretreatment blade via a parallel link to a bracket integrally fixed to the main body side, . For example, Japanese Unexamined Utility Model Publication No. 2-142123. In order to slide the cut part, a parallel link is interposed between the main body and the preload part, and the power is transmitted through the universal joint, and after the cutting, the grain straw is conveyed to the main body side threshing device by the conveying mechanism there was.

However, the above-mentioned conventional cut-out portion is inevitably fixed at the two positions of the right and left ends, and the lever for adjusting the left and right positions is located in the direction of the main body, , There was a problem in operability.

Further, in the case of skimming the grain straw by skimming, the base of the grain straw must be conveyed by the conveying device to be transferred to the supply chain, so that the rear portion of the longitudinal conveying apparatus for conveying the base of the grain straw is brought close to the supply chain , It is necessary to rotate the rear part around the center, and to rotate the whole part to the left and right corresponding to the slide of the preliminary mounting part. In addition, since this longitudinal transfer device also serves as means for adjusting the depth of supply, it is necessary to be able to rotate both vertically and horizontally. SUMMARY OF THE INVENTION The present invention is intended to provide a cutting slide mechanism that satisfies this point and is capable of connecting a longitudinal transfer device and a lifting device with a simple structure.

Since the present invention is configured as described above, the following effects are exhibited.

That is, according to the present invention, as the pretreatment mechanism of the pre-loading portion of the combine is slid, the longitudinal transporting device is linked to the ring so as to slide together. At this time, since the slide locus of the longitudinal transfer device is set parallel to the slide locus of the pre-processing mechanism, the longitudinal transfer device is moved in the same manner according to the slide of the pre-processing mechanism. At this time, since the linkage mechanism has a loose structure in which the center of the ring can freely move, it is possible to absorb the deviation and error caused by the structure, and it is possible to prevent the occurrence of warping.

Further, since the connecting portion is a ring and a rod, the contact area is small, so there is no margin in operation and no warping occurs. There is no deviation in the left and right direction due to the connection of the ring and the rod, and the positioning can be made simple. In addition, even in a combine without a slide mechanism, this positioning mechanism can be commonly used, so that the same parts can be solved, and the design cost can be reduced.

According to the present invention, since the slide operation lever 164 is provided on the upper right side of the preload portion K, the slice operation lever 64 is lifted upward from the seat 48, The sliding operation of the preload portion K is performed only by rotating the slide operation lever 164 to the left and right in a state in which the lower end portion 164c is detached from the retaining hole for determining the fixing position of the preload portion K, The slide can be fixed not only at the left and right ends but also in the middle portion thereof, so that the applicability of the package can be improved.

The slide operation lever 164 is supported at three points of the upper portion 164a, the middle portion 164b and the lower end portion 164c, and the middle portion 164b is detachably attached to the guide groove 166a It is possible to omit the number of workings for fitting the intermediate portion 164b into the round hole at the time of assembling in comparison with the support portion of the round hole and the spring 160 is provided below the intermediate portion 164b, And is pushed into the retaining hole of the lower end portion 164c, so that the lower end portion 164c can be prevented from separating from the retaining hole.
