The utility model provides a conveyer is smashed to spiral case shape straw, includes frame (1), transmission (2), housing (3), gets rid of arbor (4), carries spiral (5) and carries spiral drain pan (6), characterized by: the conveying screw (5) is positioned behind the blade throwing shaft (4), the conveying screw bottom shell (6) is positioned below the conveying screw (5), the housing (3) is positioned above the blade throwing shaft (4) and the conveying screw (5), the housing (3) is a curved surface, the longitudinal section of the housing is a curve, the curve is formed by 1-3 sections of curves, smooth transition is realized among the curves, and the curve is an arc line, a parabola or an involute.

Technical Field

The invention belongs to farmland operation machinery, and particularly relates to a straw crushing conveyor.

Background

The crop straw is crushed and returned to the field, which is favorable for improving the organic matter and nutrient content of the soil, improving the physical properties of the soil, improving the biological activity of the soil and having obvious yield increasing effect.

The existing widely popularized plastic film residue recycling machine needs to be combined with a straw crusher, the front straw crusher crushes straws and conveys the crushed straws to the two sides of a film surface or the back of a machine set, and a cleaner working surface is provided for the subsequent plastic film residue recycling machine. After the existing straw pulverizer works, a large amount of straws and fallen leaves are left on the film surface, great difficulty is brought to the subsequent operation of the residual film recycling machine, a large amount of straws are mixed in the picked residual film, and the straw returning effect and the recycling of the residual film are influenced.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide the volute straw crushing conveyor which is reasonable in structure, small in power consumption, reliable to use and low in straw falling rate.

In order to achieve the above object, the technical solution of the present invention is realized by the following measures: the utility model provides a conveyer is smashed to volute straw, includes frame, transmission, housing, gets rid of the arbor, carries spiral and carries spiral drain pan, characterized by: the conveying screw is located behind the cutter throwing shaft, the conveying screw bottom shell is located below the conveying screw, the housing is located above the cutter throwing shaft and the conveying screw, the housing is a curved surface, the longitudinal section of the housing is a curve, the curve is formed by 1-3 sections of curves, the curves are in smooth transition, and the curve is an arc line, a parabola or an involute.

The beneficial effects of the invention are as follows: after straw is crushed by the cutter throwing shaft of the volute straw crushing conveyor, the crushed straw smoothly moves along the curved surface housing and is reliably guided to the conveying screw, the falling rate of the straw is reduced, and a clean working surface is provided for subsequent residual film recovery operation.
