Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved technique of a transfer device for transferring a grain culm from a raising device of a combine harvester to a threshing unit. 2. Description of the Related Art In a conventional harvesting unit of a combine, the harvesting unit is provided with a weeding board protruding forward, and the culm which has been raked after weeding is cut off at the root of the culm. And it is passed on to the feed chain of the threshing unit by the vertical conveying device. In addition, the transporting device and the vertical transporting device are arranged and guided with a pinching guide facing each chain so as to reliably transport the grain culm, and each of them is separately biased by a spring or the like. However, since providing separate biasing members increases the cost, the present applicant has fixed both the upper conveyance banding guide and the vertical conveyance banding guide to the banding guide mounting plate to simplify the structure. And cost reduction. [0003] However, if the vertical transport clamping guide and the upper transport clamping guide are fixedly mounted on one clamping guide mounting plate, a large amount of grain is required. When the culm is transported, the volume at the base of the plant is considerably larger than the tip, so
If the vertical guide pinching guide clamps the culm and the pinching guide mounting plate is bent, a space is created between the upper conveying pinching guide and the grain culm, and the posture during transport without pinching There was a problem that the machine collapsed. [0004] The present invention has the following configuration to solve the above-mentioned problems. Attach each of the upper and lower transporting devices of the transporting device that guides the harvested grain culm to the threshing unit to the capturing guide mounting plate provided at the tip of the U-shaped rod protruding from the upper transporting device. A slit is formed in the clamping guide mounting plate to form a two-piece mounting portion, the upper conveying device clamping guide is fixed to the central side piece, and the vertical transport The guide is fixed , the clamping guide mounting plate is made of steel plate, slit
To separate the upper transfer device and the vertical transfer device.
It is made to be bendable . With this configuration, when a large number of grain culms are conveyed by the vertical conveyance device, the vertical conveyance pinching guide is greatly lifted, and the pinching guide mounting plate warps up. Since the transporting sandwich guide is attached to the upper transporting device and another mounting piece, it can be transported while holding the cereal stem with an appropriate clamping force with a small bend. The problems and constitutions to be solved by the present invention are as described above. Next, embodiments of the present invention shown in the accompanying drawings will be described. 1 is an overall side view of the combine, FIG. 2 is a front view of the same, FIG. 3 is a partial perspective view of a clamping guide mounting plate for connecting the upper conveying device / vertical conveying device and each of the clamping guides, and FIG.
