Description

[Detailed description of the invention] The invention is based on the invention: the cut crop is fed horizontally from both the left and right directions toward the center to join the cut crop at a position immediately above the cutting blade.
A starting end of a cross-feeding device and a rear-transfer device for transporting the combined crop rearward are provided, and a rake rotating body is provided at each transfer end of both cross-feeding devices and at their respective front positions. To enable a crop raking and conveying device of a reaping harvester to properly cut crops in a state as if they were being supported by hand, and to simplify the transmission structure to the raking rotating body. The present invention relates to a crop raking and conveying device in which the front left-right rotating body is interlocked with a rotating body located at the rear thereof, and its engagement position is set above the cutting blade.

In this type of crop rake conveyance device of the reaping and harvesting machine,
The larger the outer diameter of the rake rotor, the more the amount of occlusion between the front rotor and the rear rotor can be ensured, and the interlocking movement between these two can be ensured and smoothed. The facing distance between the rotational axes of the front left and right rotators becomes larger.

In other words, the distance from the longitudinal centerline of the aircraft passing through the merging point to the rotational axis of the front rotating body increases, and as a result, the crops that are raked by the front rotating body temporarily expand laterally and laterally. There is a problem in that the product is thrown around easily, causing various transportation problems such as disturbances in the transportation posture and crops falling sideways.

In view of the above-mentioned circumstances, the present invention aims to increase the outer diameter of the rake rotor to ensure and smooth the occlusal interlock between the front rotor and the rear rotor. The purpose of this system is to minimize the amount of lateral and lateral movement of crops due to It is characterized in that the upper and lower parts are overlapped.

As a result, while increasing the outer diameter of the rake rotor to ensure and smooth the occlusal interlock between the front rotor and the rear rotor, a part of the front left and right rotator can be moved vertically. Since they are placed in an overlapping position, the distance from the longitudinal center line of the machine passing through the merging point to the rotation axis of the front rotor, in other words, the amount of horizontal and lateral swing of the crop by the front rotor. It can be made as small as possible, and it is possible to suppress the occurrence of transportation troubles caused by such swinging of crops laterally and outwardly.

Moreover, the above-mentioned effects can be easily achieved by a simple structural improvement in which parts of the front left and right rotating bodies are placed in overlapping positions in the upper and lower positions.

Embodiments of the present invention will be described below based on the drawings.

The drawing shows a combine harvester, which includes a pulling device 1 that engages with the base of four planted grain culms to lift and transport them rearward and upward, and the tip and tip of the harvested grain culms. The stock head portions are locked and supported, and the posture is gradually changed to a sideways posture, and the grain is transported and supplied to the grain supply port 2a of the threshing device 2 mounted on the rear of the machine and the transport start end of the threshing feed chain 2A. Between the ear tip locking conveyance device 3 and the stock head support conveyance device 4, the base of the grain stock immediately after being cut by the clipper-shaped cutting blade 5 is placed at a position immediately above the clipper-shaped cutting blade 5. A pair of stock cross-feeding devices 6 on the left combine to transfer the stock to the center of the aircraft in the width direction
, 6', and a pair of left and right ear tip laterals that lock the tips of the grain culms immediately after harvesting, merge and transfer them to the lateral center of the machine body, and then transport them to the conveyance start end of the ear tip locking and conveying device 3. In addition to constructing the feeding devices 7, 7', transfer chains 6A, 6A which are structural members of the stock horizontal feeding devices 6, 6' are installed.
A rear transfer device 12 is constructed in which a transfer terminal end portion of the grain culm extends rearward, and the rear transfer device 12 grips the stock end portion of the merged grain culm and supplies it to the transport start end portion of the stock end support conveyance device 4 located diagonally rearward. ing.
