Abstract

DC60 (06/11/56) This invention presents a combine harvester capable of efficiently and easily performing cleaning and inspection tasks of the hopper. It comprises four grain drivers with grain-handling carriages that receive grain from the hopper, which are independently driven and rotated, loading both the cut grain into the hopper and the sorting carriage, which sorts the grain-handling material from the hopper. The sorting carriage is separated from the hopper by an independently moving sorting unit. It also comprises a support frame step 81 that supports the upper side wall 71a of the grain driver's hopper, which is independently opening and closing, and a disassembly step 80 that supports the upper side wall 71a, which is independently removable.

Claims (7)

OCR 13PL 1. A combined grain harvester consisting of a harvesting section, a harvesting section including the harvesting device, and a rotary winding unit; the rotary winding unit is driven rotaryly to rake the crop positioned toward the harvesting device, where a number of forks are mounted on the rotary winding unit in a sequence along the unit's axis of rotation, and these forks include: the terminal forks positioned adjacent to the transverse end of the rotary winding unit, and the inner forks positioned further inward of the rotary winding unit than the terminal forks, and where the bending strength of the terminal forks is defined as greater than the bending strength of the inner forks, and where the tip of the inner forks is positioned further outward radially of the rotary winding unit than the tip of the terminal forks. 2. Combine harvesters under claim 1, where the length of projection of the fork tip from its fork support is specified to be less than the length of projection of the inner fork from its fork support. 3. Combined combine harvester consisting of a harvesting section, a harvesting section including the harvesting device, and a rotary winding unit; the rotary winding unit is driven rotaryly to rake the crop positioned towards the harvesting device, where a number of forks are mounted on the rotary winding unit in a row along the unit's axis of rotation, and these forks include: a terminal fork arranged adjacent to the transverse end of the rotary winding unit and an inner fork arranged further inward of the rotary winding unit than the terminal fork, where the bending strength of the terminal fork is defined as greater than the bending strength of the inner fork, and where the extension length of the terminal fork from the fork support is defined as less than the extension length of the inner fork from the fork support. 4. Combine harvesters of any type under Reputation 1-3 where each end fork and inner fork are constructed from rounded shanks and the outer diameter of the end fork is specified to be greater than the outer diameter of the inner fork. 5. Combined rice harvesters of any type under Reputation 1-4 in which a certain number of inner forks are arranged side-by-side along the axis of rotation of the winding unit, and each two adjacent inner forks are constructed from a single shank, the shank is bent to create two inner forks at its opposite ends, and a connecting section between its shanks is connected to the fork supports. 6. Combined combine harvesters of any type under Reputations 1-5, in which a pair of fork supports extend adjacent to each other in the direction of rotation of the winding unit, and in which one group of inner forks, which has a number of inner forks supported by one fork support, is arranged out of alignment with another group of inner forks, which has a number of inner forks supported by another fork support. 7. Combined combine harvesters of any type under Reputations 1-6, in which a pair of fork supports extend next to each other in the direction of rotation of the winding unit, each fork support having a first end and a second end opposite to the first end, and in which a single fork is mounted on each first end of one fork support and the second end of another fork support, and two double forks are mounted on each second end of one such fork support and the first end of another fork support.
