Technical Field

The utility model relates to an agricultural machine especially relates to a full-feeding formula harvester header feeding auxiliary roller structure.

Background

With the rapid development of Chinese automated agriculture, the harvester becomes a necessary agricultural machine in the future. The grass blocking situation of the harvester can happen during harvesting crops every year, and many reasons are that the header can not uniformly disperse grass and then convey the grass to a threshing mechanism when the header meets a rice and wheat field with lodging and large grass amount, so that the situation can cause the following chain reactions: firstly, once the grass feeding amount is too large, the grass blocking phenomenon can occur when the grass is not conveyed in time; secondly, due to the fact that the grass feeding amount of the threshing mechanism is too large, overload can be carried out, abnormal sound of the threshing cylinder is easy to cause, long-time overload operation can increase the burden of relevant parts (a belt, a bearing and a long shaft) of the threshing mechanism, the service life of parts is shortened, and maintenance cost is increased; thirdly, uneven grass output of the crusher can be caused by uneven grass feeding amount, and soil cannot cover the places with much grass during ploughing, so that the following operation quality is affected; fourthly, as the grass amount is too large, part of grains can be threshed unclean, and the part of grains can be lost, so that the loss rate of harvesting is increased; and fifthly, once the loss rate is improved, the driver has to slow down the vehicle speed to harvest, the workload is not increased, and the oil consumption is correspondingly improved.

Detailed Description

The following detailed description of the present invention will be made in conjunction with the accompanying drawings and specific embodiments.

As shown in fig. 1, a full-feed harvester header feeding auxiliary roller structure includes: the harvester comprises a frame 1, wherein an auger 2 is arranged in the middle of the frame 1, a swing arm 3 is arranged at the upper end of the auger 2, one end of the swing arm 3 is movably connected with the frame 1 through a hinge 4, a reel 5 is arranged at the other end of the swing arm 3, one end of the swing arm 3 close to the hinge 4 is movably connected with a piston rod 8 of a reel lifting cylinder 7 through a first pin shaft 6, the tail part of the reel lifting cylinder 7 is movably connected with the frame 1 through a second pin shaft 9, the reel lifting cylinder 7 is connected with a header hydraulic quick joint 11 arranged on the frame 1 through a first lead 10, the header hydraulic quick joint 11 is connected with a hydraulic control switch on a harvester operating platform through a second lead, a cutter 12 is arranged on the frame 1 at the lower end of the reel 5, and an auxiliary roller 13 is rotatably arranged in the lower end of the frame 1 between the cutter 12, the reel 5 and the auger 2, one end of the auxiliary roller 13 is provided with a driven sprocket 14, an adjustable speed motor 15 is arranged inside the lower end of the rack 1 between the auxiliary roller 13 and the auger 2, a driving sprocket 17 is arranged on a motor shaft 16 of the adjustable speed motor 15, the driving sprocket 17 is connected with the driven sprocket 14 through a chain 18, the adjustable speed motor 15 is connected with an auxiliary roller speed regulation quick joint 20 arranged on the rack 1 through a third lead 19, the auxiliary roller speed regulation quick joint 20 is connected with an auxiliary roller speed regulation switch 22 on a harvester operating platform through a fourth lead 21, and a gap bridge 23 is arranged on the rack 1 on one side, far away from the reel 5, of the auger 2.
