Description

Straw crushing type bundling machine

Technical Field

The invention belongs to the technical field of agricultural and animal husbandry machinery, and particularly relates to a crushing and dedusting square bundle bundling machine for harvesting crop straws.

Background

After the corn plants are harvested by agricultural growers, the corn straws are usually recycled as feed to feed animals such as cattle and sheep. But the manual operation is time-consuming and labor-consuming. The mechanical single-roller crushing square bundle baler solves the problems of crushing, collecting and baling one long bundle and has high efficiency. However, due to the limitation of the single-roller crusher, the crushed feed has different sizes and is not suitable for cattle and sheep animals.

Application publication No. CN 104303728A discloses a crushing type square bundle baler, which enters the square bundle baler to be bundled after straws are crushed by a crusher, and the square bundle baler has small bundling density and small bundle formation, and is not suitable for picking and bundling large and medium-sized square bundles; it is divided into a front crushing cavity and a rear crushing cavity, and occupies a large area.

A smashing and dust removing square bundle bundling machine is disclosed in the patent CN201821809774.9, under the traction action of a tractor, a flail knife shaft (2-6) picks up materials on the ground, the materials are preliminarily smashed by the flail knife shaft (2-6) and then input into a transverse conveying smashing shaft (2-15), the smashed materials are blown to a grass collecting conveying mechanism (3) through fan blades (2-15-6), dust is removed when the materials are blown to the grass collecting conveying mechanism (3), the materials are input into a square bundle machine (4) through a bidirectional auger (3-4) of the grass collecting conveying mechanism (3), and a working cycle from grass scattering to smashing, dust removing and bundle compressing is completed.

However, when the spiral blades of the transverse conveying crushing shaft convey straws with large conveying capacity, a block can be formed, and due to the large feeding quantity of the crushing blades, the crushing blades cannot crush the straws in place, so that the feeding standard of livestock cannot be met.
