Round bundling machine for combine-harvester

Abstract

The invention discloses a round bundling machine for a combine-harvester. The machine comprises a bundling machine box, a hopper feeding port is arranged at the top end of the left side edge of the bundling machine box in an embedded mode, and a shifting fork feeding mechanism is installed in a rail of the hopper feeding port; a compressor is fixedly connected to the top end of a box cover of the bundling machine box in a welded mode, an eccentric shaft is transversely connected between left and right shells of the bundling machine box, threaded holes are formed in the eccentric shaft at equal intervals, rotating steel rollers are connected in the threaded holes in a penetrating mode, the front end of the eccentric shaft is connected with a main driving shaft through a telescopic flange sleeve in a sleeved mode, the tail end of the eccentric shaft is connected with an eccentric connecting rod through a sleeve in a sleeved mode, and the tail end of the eccentric connecting rod is connected with a driving linage mechanism; a discharging port is formed in the joint, on the bottom of the bundling machine box, between the shells, a flexible door is arranged in the discharging port in an embedded mode, one end of the flexible door is connected with the box through a flexible hinge, and the other end of the flexible door is provided with an open-close air pump. By means of the machine, blocking of the feeding port by forage is avoided, a compressing bundling mechanism is simple and small in size, a driving mechanism has good stability performance, and the automation degree of automatic forage feeding is high.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a round baler for combine harvesters. Background technique [0002] Before the popularization of mechanized harvesting, wheat and rice straws were widely used as important daily fuel and dry feed in rural areas. However, with social progress and the popularization of mechanized harvesting technology, straws were discarded and burned everywhere, resulting in waste of resources, environmental pollution and Problems such as frequent fire accidents have become increasingly prominent. On the one hand, its function as daily fuel is gradually disappearing, and farmers have no enthusiasm for collecting straw; on the other hand, harvesting machinery usually throws or crushes wheat and rice straw in the field, which not only wastes resources, but also is not conducive to the planting and harvesting of next crops.

Problems solved by technology

[0002] Before the popularization of mechanized harvesting, wheat and rice straws were widely used as important daily fuel and dry feed in rural areas. However, with social progress and the popularization of mechanized harvesting technology, straws were discarded and burned everywhere, resulting in waste of resources, environmental pollution and Problems such as frequent fire accidents have become increasingly prominent

On the one hand, its function as a daily fuel is gradually disappearing, and farmers have no enthusiasm for collecting straw; on the other hand, harvesting machinery usually throws or crushes wheat and rice straw in the field, which not only wastes resources, but also is not conducive to the planting and harvesting of next crops. Field management, which has caused social problems such as straw burning

[0003] In order to protect the ecological environment, farmers generally use the following methods to clean up straw: directly returning to the field, manual cleaning, and picking and bundling. Among them, picking and bundling and reprocessing is the most economical way, and balers are generally used for straw cleaning. For the bundling operation, a bundling device is now added to the combine harvester, but the existing bundling device uses a picker to load the material, which is easy to cause the feeding port to be blocked, and the internal bundling mechanism has a complex structure and takes up a large volume. Not suitable for small instruments
