Three-roller corn picking and straw smashing device

Abstract

The invention relates to a three-roller corn picking and straw smashing device, comprising a decelerating transfer case assembly, a corncob picking platform and a stalk-chopped roller. The corncob picking platform is fixedly installed at the front end of the decelerating transfer case assembly and is a bilateral symmetric structure with longitudinal seams arranged therebetween, the width of the longitudinal seam is smaller than the diameter of a corncob; reel chain assemblies are symmetrically installed on the decelerating transfer case and the upper surfaces of the two sides of the longitudinal seams; three coaxial stalk-chopped cutters are lengthways installed in the corncob picking platform; the middle notches of the three stalk-chopped cutters are just opposite to the longitudinal seams of the corncob picking platform; and the input shaft ends of the three stalk-chopped cutters are installed in the decelerating transfer case assembly. The invention has simple integral structure as well as scientific and reasonable design, realizes the smashing of straws while reaping corn ears, improves the work efficiency of a corn harvester, increases the corn yields, promotes the updating of the corn harvester, and has very important practical significance to the agricultural development.

Description

Technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a corn harvester, in particular to a three-roller corn picking and straw crushing device. Background technique [0002] Ear picking and straw smashing are proposed to solve the air pollution caused by the burning of stalks and the development of animal husbandry. That is, when the corn ears are harvested, the stalks are chopped and collected or returned to the field. Foreign corn is mostly planted once a year. After the corn is harvested, the stalks are returned to the field, and the winter slack is used for deep ploughing into the soil and fertilizer. In areas where wheat and corn are grown twice a year, with the development of industrial fuels, straw used as the main fuel in rural areas has become a waste of incineration and polluting the air in the field, and the rapidly developing animal husbandry needs a lot of feed. Therefore, it is of great significance to develop a corn ha...

Problems solved by technology

[0004] At present, the current situation of corn harvesters in my country does not fundamentally solve the corn harvesting problem that meets the needs of the existing national conditions and agronomic conditions in terms of working principle and structure. stem function, and straw crushing is carried out in the pulverizer, resulting in low straw crushing efficiency and poor ear picking ability
