A shearing crop stalk cutter

Abstract

The invention relates to a shear type crop stem cutter, which comprises a housing. A transmission mechanism is arranged in the housing; a shearing mechanism connected with the transmission mechanism is arranged below the housing; the transmission mechanism comprises an inner shaft I, an outer shaft II and a transmission shaft III; the outer shaft II is a hollow shaft; the outer shaft II sleeves the inner shaft I; the inner shaft I, the outer shaft II and the transmission shaft III are fixed on the housing 1; the inner shaft I is connected with a bevel gear I; the outer shaft II is connected with a bevel gear II; the transmission shaft III is connected with a bevel gear III; the bevel gear III is respectively meshed with the bevel gear I and the bevel gear II; the shearing mechanism comprises an upper disk cutter and a lower disk cutter which are clung to each other; the lower disk cutter is connected to the inner shaft I; the upper disk cutter is connected to the outer shaft II. The cutter utilizes a shearing principle of shears so as to enable surfaces of cut stubbles to be flat, has the characteristics of simple structure, easiness for fabrication, safety, reliability and the like, and has high practicality and wide popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, in particular to a shearing crop stalk cutter. Background technique [0002] Crop stalk cutting and harvesting is an important part of crop production, so research on crop stalk cutters has also been vigorously developed. The most widely used cutters are reciprocating cutters, and some circular saws are also used on lawn mowers. However, the traditional scissors are used less and less. When using reciprocating cutters or circular saw blades, it will cause different degrees of mechanical damage to the crop stubble, and the quality of the stubble will decrease, which will affect the economic benefits of farmers, especially for mulberry crops. Crops such as stalks, alfalfa, and wicker need to have better stubble quality. In addition, when the machine is working in the field, it will inevitably encounter obstacles, stones, etc. Whether it is a traditional reciprocating ...
