Self-propelled twisting crop first removes and then cuts threshing and cutting rod integrated harvester

Abstract

The invention discloses a self-propelled twisting harvester that first removes grain and then cuts threshing and cutting rods, and belongs to the technical field of harvesting equipment in agricultural machinery, including a frame and a power mechanism, a transmission mechanism, a walking mechanism, a threshing mechanism, a conveying mechanism, The cutting mechanism and the threshing mechanism include a threshing box, a threshing drum, and a grain guide, and the grain guide includes a grain guide chain, a plurality of grain guide sprockets, and a plurality of grain pressing bars, which are overhead and fixed on the grain guide The grain chain moves back and forth with the grain guide chain. The grain guide chain is located above or above the side of the threshing drum. It forms multiple continuous "V" shapes near the threshing drum, and the grain pressing bar moves to multiple "V" shapes. The bottom end of the threshing cylinder has multiple nearest tangent points, and the surface of the threshing cylinder is provided with multiple threshing teeth; the threshing box can be lifted and mounted on the frame. The invention has a simple structure, continuously and dynamically twists the straw, changes the striking direction, strikes the ear tip of the grain several times, achieves thorough threshing, automatic cleaning, and high efficiency.

Description

technical field [0001] The invention relates to a harvesting device in an agricultural machine, in particular to a self-propelled twisting harvester capable of both threshing and ear harvesting as well as harvesting threshing and cutting rods. Background technique [0002] In the prior art, rice combine harvesters are mostly large-scale equipment, suitable for use in plain areas, and the harvesting methods have two types: full feeding and half feeding. Full-feeding is to cut off the ears of rice together with the rice stalk, and send them all to the harvester for threshing, and then divide the grain and grass. Carry out aspartate and grass separation again. In the prior art, there are also a small amount of harvesters that are free from feeding, first threshing and then cutting rods, such as "a self-propelled miniature harvester for threshing before cutting" as the publication number CN203467221U, and the "feeding less, first harvesting" patent No. 200910044696.7 The thres...

In the prior art, there are also a small amount of harvesters that are free from feeding, first threshing and then cutting rods, such as "a self-propelled miniature harvester for threshing before cutting" as the publication number CN203467221U, and the "feeding less, first harvesting" patent No. 200910044696.7 The threshing process is the threshing drum rotating threshing, without considering the cooperation with the grain guiding device and the grain pressing device, the effective threshing path is short, the impact points are few, and the impact time is short. It is short and the threshing effect is not good; the crops are cut with rotary knife rollers, the structure is complex and the cost is high, and it is necessary to install an exhaust fan for cleaning
