Embodiment 1

[0018] Embodiment 1: A straw harvester, comprising a frame 1, a threshing device 4 at the rear of the frame, a straw separation device 5 located below the separation device 4, the straw separation device 5 includes a straw conveying mechanism 2, and a beating mechanism 3 , the straw conveying mechanism includes a driving wheel 21, a transmission shaft 22, a driving lever 23, a ratchet 25, and a conveying device 26. The driving wheel 21 is rotationally connected with the frame 1, and the driving lever 23 is connected to the driving wheel 21 is fixedly connected, the end surface of the driving rod 23 is fixedly provided with a driving rod roller 24, the conveying device 26 includes a conveyor belt 262, a drive shaft 261, and the drive shaft 261 is fixedly connected with the ratchet 25, and the conveyor belt 262 is Reticulate, described beating mechanism 3 is connected with driving wheel 21 transmission, and described beating mechanism 3 comprises belt pulley 31, axle 32, eccentri...

Embodiment 2

[0022] In order to realize the present invention better, reduce the wearing and tearing of ratchet 25 and lever roller 24, in conjunction with attached image 3 , In this embodiment, the lever roller 24 is provided with a bearing. The purpose of arranging the bearing is to make the frictional force between the lever roller 24 and the groove 251 be a rolling friction force, which reduces the frictional force, thereby reducing the wear of the lever roller 24 and the groove 251 .

[0023] combined with figure 2 , the ratchet 25 is at least uniformly provided with four grooves 251 . The purpose of such setting is that the more the grooves 251 of the ratchet wheel 25 are, the shorter the conveying device 26 transports the straw per unit time, and the higher the beating frequency of the straw is, so as to further separate the grain entrained in the straw and reduce waste. It should be emphasized here that, in this field, the number of grooves 251 is limited by the size of the rat...

Abstract

The present invention discloses a straw harvester, and relates to the technical field of agricultural machinery. The straw harvester comprises a rack, a threshing device at the tail of the rack, and a straw separating device below the threshing device, wherein the straw separating device comprises a straw conveying mechanism, and a beating mechanism. The straw harvester has the advantages of being simple in structure, reliable and durable, and can be used for solving a technical problem of separating cereals carried in straws, reducing the grain waste and increasing the yield of the harvester.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a straw harvester. Background technique [0002] The harvesting, threshing, separation of stems, removal of debris and other processes of cereal crops are completed at one time, and the grain harvesting machinery that directly obtains grains from the field is referred to as a combine harvester. Its advantages are high labor productivity, low labor intensity, and it can catch up with the farming season, and it is suitable for use in places with large plots of land. According to the threshing method, combine harvesters are divided into combing type and feeding type. Because the combing machine has some shortcomings in terms of reliability and matching, it is still in the promotion stage of the prototype, so at present, the feeding combine harvester is mainly used, that is, the plants are first cut off and then threshed through the threshing device as a whole. [00...
