Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] A two-speed straw crushing and threshing roller matched with a combine harvester, such as figure 1 , 2 As shown, it includes a fixed frame 1, a central concentric bearing 4 fixed on the fixed frame 1, a threshing roller 3 fixed on the outer bearing 21 of the central concentric bearing 4 and an inner bearing 22 fixed on the central concentric bearing 4 The straw crushing knife 2, and the large gear 5 fixed on the outer end of the outer bearing 21 warehouse of the Zhongtong concentric bearing 4 and the pinion 6 fixed on the outer end of the inner bearing 22 of the Zhongtong concentric bearing...

Abstract

The invention provides a two-speed straw smashing and threshing roller wheel matched with a combine harvester without changing the structure of an existing combine harvester. The roller wheel comprises a fixing frame, hollow concentric bearings, a threshing roller wheel body, a straw smashing blade, a large gear and a small gear. Under the condition that the original structure of the combine harvester is unchanged, the two-speed straw smashing and threshing roller wheel replaces an original threshing roller wheel of the combine harvester, and two gears of the same size are fixed on an original power bearing of the combine harvester and connected with the large gear and the small gear arranged on the hollow concentric bearings respectively through chains. Two different rotating speeds of the hollow concentric bearings are achieved through different rotating speeds of the large gear and the small gear, so that the rotating speed of the straw smashing blade is much larger than that of the threshing roller wheel body. In this way, straws can be crushed more thoroughly, and the field returning effect is ideal.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a two-speed straw crushing and threshing roller matched with a combine harvester. Background technique [0002] When harvesting wheat, rice and other crops, the existing combine harvester cannot crush the stalks in the working compartment. The swallowed stalks will not only hinder the next round of plowing, but also affect the operation of the rotary tiller. Currently, the most commonly used treatment method is Incineration, however, on the one hand, treating straw through incineration will waste the straw with potential nutrition, on the other hand, the smoke generated by combustion will cause great pollution to the air, especially when large-scale incineration, sulfur dioxide, The three pollution indexes of nitrogen and inhalable particulate matter reached their peaks, among which the concentration of sulfur dioxide was twice as high as usual, and the concentration of nitr...
