Problems solved by technology

However, in this header transmission device of the prior art, when harvesting crops, each transmission mechanism is easy to collide with the field ridge; and the transmission is all on one side so that the center of gravity of the header is to the right, which is not conducive to left and right balance, and is even more unfavorable for shock absorption and noise reduction.
The cutter of the pre-processing device of the combine harvester is driven by a swing ring structure, which is costly and difficult to maintain

Embodiment Construction

[0022] A kind of combine harvester, the delivery trough 241 on the body, the dustpan-shaped header frame 11 at its front, the cutter 13 at the mouth of the dustpan, the reel 12 at the front and upper side, and the header stirrer at the rear of the dustpan. Dragon 15, straddle the frame and support the reel strut 12A on the rear top of the frame and the header transmission device 16 that transmits the power to the above-mentioned components. This header transmission device is made up of bridge device 164, transitional transmission mechanism 16A, crank link mechanism 163. One end side and the other end side of the intermediate shaft 45 of the driving force of the engine transmit the power forward and backward respectively, and transmit the power forward to the gear box 35. The driving force is transmitted to the bridge transmission shaft 161a, and the bridge transmission shaft 161a transmits the driving force to the header auger 15 and the crank linkage mechanism 163, and the he...

Abstract

The invention provides a header for combine harvesters. The header comprises a dustpan header frame (11), a cutter (13) at an opening of a dustpan, a reel (12) in the upper front, a header screw (15) in the inner rear of the dustpan, a reel support bar (12A) crossing the frame and supported above the rear of the frame, and a header transmission mechanism transmitting power to the former parts. Power for the cutter (13) is input from the left by a bridge transmission shaft (161a) transversely arranged in the rear of the dustpan header frame; power for the cutter screw (15) and the reel (12) is input from the right by a reel transmission shaft (129b) mounted in the reel support bar. Part of the transmission structures of the header are arranged on the left; compared with the prior transmission, the header has the advantages that bilateral balance is facilitated, shock absorption and noise reduction are also facilitated, bridge transmission is achieved with a crank and link mechanism rather than the prior swing ring structure, and the header is simple in structure, low in cost and convenient to maintain.

Description

technical field [0001] The invention relates to a header of a combine harvester, in particular to the structure and transmission mode of the header transmission device. Background technique [0002] The transmission device of the existing combine harvester is usually arranged on the right side of the header frame. For example, the utility model patent CN20326177U discloses a pretreatment device of a combine harvester. The right side of the horizontal end of the harvester frame is provided with a transmission mechanism for the harvesting knife, a transmission mechanism for the header auger, and a transmission mechanism for the reel. However, in this header transmission device of the prior art, when harvesting crops, each transmission mechanism is easy to collide with the field ridge; and the transmission is all on one side so that the center of gravity of the header is to the right, which is not conducive to left and right balance, and is even more unfavorable for shock absor...
