Secondary separation mechanism of harvester

Abstract

The invention discloses a secondary separation mechanism of a harvester. The secondary separation mechanism of a harvester comprises a roller, a vibrating screen, a straw feeding plate, a supporting plate, a separation tube and a feeding opening, wherein the vibrating screen is arranged on the outer wall of the bottom end of the roller; the straw feeding plate is arranged in a position, positionedon the outer wall of the vibrating screen, of the roller;; the supporting plate is connected onto the outer wall of the bottom end of the straw feeding plate through screw bolts; the separation tubeis rotationally arranged on the outer wall of one side of the roller; the feeding opening is formed in the outer wall of the bottom end of the separation cylinder; one end of the straw feeding plate is inserted into and connected with the inside of the feeding opening; and the roller and the separation tube are in a cylindrical shape. The secondary separation mechanism of the harvester is used forperforming secondary separation on grain particles and rice and wheat straws when the harvester is used for harvesting rice or wheats, so that the grains and the straws can be more cleanly separated;the retention rate is improved; the entrainment loss of grains is reduced; in addition, the structure is simple; the operation efficiency is high; the grain and straw separation effect is good, so that the grain waste is reduced; and the economic benefits of farmers are increased.

Description

technical field [0001] The invention relates to the technical field of harvester auxiliary equipment, in particular to a harvester secondary separation mechanism. Background technique [0002] The harvester was invented by Cyrus McCormick; and the harvester is an integrated machine for harvesting crops; it completes harvesting, threshing, and concentrates the grains into the storage bin, and then transports the grain through the conveyor belt On the transport vehicle, it can also be manually harvested, laying the stalks of rice, wheat and other crops in the field, and then picking up and threshing with grain harvesting machinery; crop harvesting machinery for harvesting rice, wheat and other cereal crops and straw; including Harvesters, windrowers, balers, grain combine harvesters, and grain threshers, etc.; grain harvesting machinery is developed on the basis of various harvesting and threshing tools, and in the process of harvesting, a separation mechanism is required.

[0002] The harvester was invented by Cyrus McCormick; and the harvester is an integrated machine for harvesting crops; it completes harvesting, threshing, and concentrates the grains into the storage bin, and then transports the grain through the conveyor belt On the transport vehicle, it can also be manually harvested, laying the stalks of rice, wheat and other crops in the field, and then picking up and threshing with grain harvesting machinery; crop harvesting machinery for harvesting rice, wheat and other cereal crops and straw; including Harvesters, windrowers, balers, grain combine harvesters, and grain threshers, etc.; grain harvesting machinery is developed on the basis of various harvesting and threshing tools, and in the process of harvesting, a separation mechanism is required. The rice is separated, but when the existing harvester harvests the rice and wheat, the grain and the grass part separated by the drum cannot be separated twice, which makes a small part of the rice still exist on the rice grass, which cannot be separated cleanly, and a lot of food is wasted. Unable to improve grain retention
