Self-propelled stalk-twisting integrated harvester carrying out threshing before stalk cutting

Abstract

The invention discloses a self-propelled stalk-twisting integrated harvester carrying out threshing before stalk cutting, and belongs to the technical field of harvesting equipment in agricultural machines. The integrated harvester comprises a rack, a power mechanism, a transmission mechanism, a walking mechanism, a threshing mechanism, a conveying mechanism and a cutting mechanism. The threshing mechanism comprises a threshing box, a threshing roller and a stalk guider, the stalk guider comprises stalk guiding chains, multiple stalk guiding chain wheels and multiple stalk pressing cross rods, the stalk pressing cross rods are fixed to the stalk guiding chains in an overhead mode and circularly move along with the stalk guiding chains, and the stalk guiding chains are located over or above the threshing roller; multiple continuous V shapes are formed between the stalk guiding chains and the threshing roller, when the stalk pressing cross rods move to the bottom ends of the multiple V shapes, multiple closest tangent points are formed between the stalk pressing cross rods and the threshing roller, and multiple threshing teeth are arranged on the surface of the threshing roller; the threshing box is installed on the rack in a liftable mode. The self-propelled stalk-twisting integrated harvester is simple in structure, continuously and dynamically twists rice stalks, changes the striking direction, and strikes ear tip positions of the stalks many times to achieve thorough threshing, automatic screening is achieved, and efficiency is high.

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
