Novel green fodder harvester

Abstract

The invention belongs to the technical field of agricultural machinery, and provides a novel green fodder harvester. The novel green fodder harvester comprises a harvester body, a feeding device, a chopping device, a grain crushing device and a throwing device, wherein the grain crushing device comprises a fixing roller, a rotating frame, a floating roller, a regulating wedge block, a gap regulating screw rod and an elastic device; the fixing roller is rotationally arranged on the harvester body; the rotating frame is rotationally arranged on the harvester body; the floating roller is rotationally arranged on the rotating frame, and a gap between the fixing roller and the floating roller form a material passage; the regulating wedge block is glidingly arranged on the harvester body, and the inclined surface of the regulating wedge block is in contact with the side wall of the rotating frame; the gap regulating screw rod is arranged on the machine body, and the end part of the regulating screw rod is connected with the regulating wedge block; and the elastic device is used for providing elastic force for enabling the rotating frame to approach to the fixing roller. By the technicalscheme, the problems of regulation inconvenience and inaccuracy during crushing rate regulation of the green fodder harvester in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a novel green forage harvester. Background technique [0002] With the development of our country's economic level and the improvement of residents' dietary structure, the demand for cattle, sheep dairy products and meat and eggs is also increasing year by year. Silage and harvesting machinery are among the developments in the development of cattle and sheep breeding industry and the production of feed crops. An important part of the green forage harvester is an agricultural mechanical device mainly used to harvest green forage crops such as green forage, oats, beet stems and leaves, corn, etc., to produce green forage growing in the field into green shredded products. [0003] Green forage harvesters are generally equipped with a grain crushing device, which is used for secondary crushing of materials, crushing granular crops, increasing the crushing rate, and improv...
