Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for driving a cutting slide in a combine. 2. Description of the Related Art Generally, a harvesting unit of a combine is supported so as to be able to move up and down in front of a machine body without sliding, and a hydraulic cylinder is used as a drive device for raising and lowering the harvester. [0003] As a driving device for the mowing slide, there has been a hydraulic cylinder system using a hydraulic cylinder, or a mechanical system using a screw feed mechanism using an electric motor or engine power as a driving source. [0004] In the conventional mowing slide driving device, any of the hydraulic cylinder system and the mechanical system is disadvantageous in terms of cost and weight. The hydraulic cylinder, and in the case of the mechanical system, the screw feed shaft and its case are located below the cutting part, so that the space of this part is narrowed and mud accumulation and the accumulation of straw waste are easy. Not only did this occur, but this also hindered the slide. According to the present invention, there is provided a driving device for a cutting slide for sliding a cutting unit without having a dedicated driving source for the cutting slide and without reducing the space below the cutting unit to solve all the above-mentioned problems. It is intended to provide. In order to achieve the above object, a cutting slide driving device according to the present invention is provided with a cutting section in which a cutting section supported to be movable up and down in front of the body is slid in the left and right direction of the body. The slide drive device includes a drive mechanism that pulls and slides the reaping section left and right via left and right slide wires, and the drive mechanism pulls the slide wire using a mowing lift operation. The mowing slide driving device of the present invention configured as described above raises the mowing portion with a hydraulic cylinder for raising and lowering the mowing, and moves the mowing portion left or right by the mowing raising operation. Slide. An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional side view of a drive unit of a cutting slide, FIG. 2 is an overall side view of a combine, and FIG. 3 is a plan view of the combiner, where (1) is a track frame on which a left-right traveling crawler (2) is mounted; (3) is a machine frame installed on the track frame (1), (4) is a threshing unit in which a feed chain (5) is stretched to the left and a handling cylinder (6) is installed, and (7) is a grain. A mowing unit provided with a culm vertical conveying device, (8) a straw processing unit, (9) a driver's cab provided with a driver's seat (10) and a driving operation unit (11), (12) a threshing unit (4) Floating the grain into a fryer (1
3) a grain tank for storing the grain, (14) a discharge auger for taking out the grains in the grain tank (12) outside the machine, (1)
Reference numeral 5) denotes an engine for driving each part of the combine, which is configured to continuously perform harvesting and threshing work. As shown also in FIGS. 4 and 5, the cutting section (7)
Is a three-row raising case (18) having a raising tine (17) for raising an uncut culm taken in through a weeding board (16), and a star for scraping the culm base side of the raised cereal culm. A foil (19) and a scraping belt (20), a cutting blade (21) for cutting the stem side at the time of scraping, and a diagonally left side of the stem side and the tip side of the grain stem of one right after cutting. Right culm conveying chain (22) and a pair of upper right and lower right tine conveying tines (23) to be conveyed to the rear, and right culm base obliquely rearward on the culm side and spike side of the two left grain culms after cutting. It has a left culm base transfer chain (24) and a pair of upper and lower right ear tip transfer tines (25) that join near the feed end position of the transfer chain (22), and also joins the feed end of the right culm base transfer chain (22). Do 3
A vertical transport chain (2) that transports and receives the culm side and the tip side of the grain culm to the feed start end of the feed chain (5).
6) and a vertical transport tine (27), and the harvested grain culm of three rows is transported by the right and left culms of the cutting unit (7).
(22) and the feed chain (5) via a Y-shaped grain culm transfer path formed by the right and left spike transfer tines (25) and (23), the vertical transfer chain (26) and the vertical transfer tine (27).

The cutting operation is switched to the on state shown in FIG.
By increasing the amount of the slide wires (76) and (77) withdrawn from the cutting mechanism (7) via the left and right slide wires (76) and (77) as in the drive mechanism (78) described above. It is configured to be driven by slide. Since the present invention is configured as described above, the following effects can be obtained. In a cutting slide driving device for sliding a cutting unit (7) supported on the front of the machine so as to be able to move up and down freely, a left and right slide wire (76) is provided.
A drive mechanism (78) (78a) for pulling and sliding the mowing part (7) to the left and right via the (77) is provided, and the driving mechanisms (78) (78a) utilize a slide wire (76) utilizing a mowing raising operation. ) Since (77) is pulled, a drive source dedicated to the mowing slide is not required, a simple structure in which the space below the mowing portion (7) is not narrowed can be achieved, and cost reduction and weight reduction can be achieved. It is possible to prevent the accumulation of mud and the accumulation of straw chips at the lower part of the cutting unit (7), and the slide is not hindered thereby. Further, since the power of the hydraulic cylinder for raising and lowering the reaping can be used, even if the reaping part (7) having three or more sections is heavy, it can be smoothly and smoothly slid. Further, since the mowing part (7) does not slide unless the mowing part (7) is raised to a predetermined position, damage to each part due to an operation error in which the mowing part (7) is slid in a grounded state is anticipated. Can be prevented.
