Harvesting header and working method thereof

Abstract

The invention provides a harvesting header. The harvesting header is characterized in that a reel chain device is mounted at the front end of a feeding auger, and a divider is mounted on each reel chain mounting frame plate; the reel chain device comprises a gear transmission box body, and the gear transmission box body is connected with a header body in a hinged mode; each reel chain mounting frame plate is mounted on the gear transmission box body, a plurality of gears are horizontally arranged in the gear transmission box body side by side, and the gears are meshed with one another; the gear transmission box body is coaxial with the gears and is upwards connected with a reel chain wheel; the gear transmission box body is connected with an angle reversing transmission box, the angle reversing transmission box is connected with a first belt wheel, and the first belt wheel is connected to the driving wheel; and cutters are positioned on the lower side of the rear end of the reel chain device, are mounted on the gear transmission box body and are continuously and uniformly arranged in a full-width manner. The structure in the gear transmission box body is that a plurality of mutually meshed gears are horizontally arranged side by side; the gear transmission box body is relatively small in thickness and light in weight; and therefore, the height of the front side of the harvesting header can be reduced, so that the height of the cutters is reduced, and ground-attached harvesting is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, in particular to an improved harvesting header and a working method thereof. Background technique [0002] In recent years, the yield of crop machines in our country has been increasing year by year. The harvesting table in the existing technology is basically the reel chain, which is the reel cutting transmission method. At the same time, the cutter cuts off the ear heads and continues to be pushed to the feeding auger by the reel chain, and pushes the ear heads to the main feeding inlet in the middle of the header, and the ear heads are moved to the conveying trough by the telescopic tooth rod of the auger. . In the operation process, there are also the following defects: [0003] (1) The movement of the reeling chain is driven by the power provided by the transmission box. The transmission box is a transmission box structure combining shafts and sprockets, and each reeling cha...

Problems solved by technology

[0003] (1) The movement of the reeling chain is driven by the power provided by the transmission box. The transmission box is a transmission box structure combining shafts and sprockets, and each reeling chain structure is driven by a separate transmission box. wheel connection; not only the structure is complex, but also cumbersome to assemble; moreover, the structure of multiple transmission boxes is heavy, resulting in heavy header, which limits its scope of use; moreover, a support beam is installed outside the transmission box, so The height of the transmission box is limited, and the cutter can only be installed at the rear end of the reel chain. If the installation position of the cutter is lowered, the stubble height can be reduced, but because the distance between the cutter and the reel chain is far away, it is impossible to harvest lodging and tilting crops; the height of stubble cannot be reduced, which will cause new difficulties for the collection of grain and grass in the later stage and land preparation; for example, because the stubble is too high, it is difficult to operate when planting new crops, including field management of crops, which is inconvenient; in crops When harvesting again, the pushing action of the grain divider causes new crops to fall, and the harvesting loss is serious;

[0004] (2) In the setting method of the cutter, due to the transmission structure design of the reel chain, the cutter can only be set in the channel of the crop divider, and the cutter cannot be installed on the lower side of the crop divider or other positions, resulting in non-upright State crops are poorly harvested;

[0005] (3) Because the transmission box is separated and independent, the header is too heavy, the transmission is complicated, it is easy to damage the grass, and the harvesting efficiency is low
