Abstract

The utility model relates to a maize straw mincing field returning device, and belongs to the field of agricultural machines. The maize straw mincing field returning device comprises a machine frame, wherein a cutter roll shaft is arranged on the machine frame. The maize straw mincing field returning device is characterized in that a shell guard plate is fixed to the bottom of the machine frame; movable cutting heads are arranged on the cutter roll shaft and are distributed on the cutter roll shaft spirally in a stepped mode; movable blades are arranged on the movable cutting heads; and fixed blades are arranged corresponding to the movable blades and are fixed to a shell guard plate. According to the maize straw mincing field returning device, the movable cutting heads are arranged on the cutter roll shaft and are distributed on the cutter roll shaft spirally in a stepped mode, so that a phenomenon of no laterality is realized, the stability of the cutter roll shaft during operation can be ensured effectively, and the maize straw mincing field returning device is simple in structure, small in size, small in required power and high in efficiency; due to the adoption of the shell guard plate, a channel for leading crushed straw out is provided, so that the straw is scattered in the field uniformly, and the movable blades are prevented from injuring people when dropped effectively; and included angles between cutter bodies and cutting edges on the movable blades are 45 degrees, so longitudinal cutting and transverse cutting can be performed simultaneously during operation.

Description

The shredding corn stalk returning device

Technical field

The utility model relates to a kind of shredding corn stalk returning device, belongs to field of agricultural machinery.

Background technology

Existing two row corn combines, very high because also the field adopts hand hay cutter to cut hob type field-returning machine structure more to snapping bar and field-returning machine status requirement, can only adopt short snapping bar, harvesting efficiency is reduced.When adopting long snapping bar, the preceding partially end-grain cutting of field-returning machine less than, partially afterwards no clamping device can not normally feed, and causes the stalks cutting weak effect, and blockage often occurs.

The utility model content

According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of shredding corn stalk returning device is provided, and it is simple in structure, and volume is little, and required drive is little, and efficient is high.

The described shredding corn stalk returning device of the utility model comprises frame, and tool roller axis is installed on the frame; It is characterized in that: the frame bottom is fixed with the housing backplate; Tool roller axis is provided with the moving knife seat, and moving knife seat stepped spiral on tool roller axis distributes, and on the moving knife seat, knife section is installed; Corresponding knife section is provided with ledger-plate, and ledger-plate is fixed on the housing backplate.

Adopt the housing backplate, the one, for the stalk of pulverizing provides the passage of a derivation, it is scattered in the field equably; The 2nd, prevented effectively to fly out when knife section from coming off and hurted sb.'s feelings; Adopt moving knife seat stepped spiral on tool roller axis to distribute, can reach not have and lay particular stress on phenomenon, can guarantee the stability of tool roller axis when work effectively, it is simple in structure, and volume is little, and required drive is little, and efficient is high; The moving knife seat is used to install knife section.

The utility model is in order to realize vertically cutting and transverse cuts, and said knife section comprises blade, and blade is a tulwar shape, and the blade cut end is provided with the profile of tooth blade.

In order further to improve the effect of vertically cutting and transverse cuts, the bent angle of the preferred blade of the utility model is 45 degree, and blade is arranged on the blade both sides, and said bent angle is the angle of tulwar shape blade two bent faces.

Wherein, said tool roller axis one end is equipped with drive sprocket, makes things convenient for the transmission of power.

During work, frame is fixed on the ceding of Taiwan frame of two row corn combines, again drive sprocket is linked together through the sprocket wheel on chain and the ceding of Taiwan intermediate propeller shaft; When ceding of Taiwan intermediate propeller shaft turns clockwise; Will drive drive sprocket and begin to rotate, drive tool roller axis and rotate, under the effect of moving knife seat; Knife section begins to throw around the tool roller axis high speed rotating and with stalk; Under the cooperation of ledger-plate and knife section, stalk is pulverized, then through the housing backplate for the stalk of pulverizing provides the passage of a derivation, it is scattered in the field equably.

Compared with prior art, the utlity model has following beneficial effect:

1, owing to adopt moving knife seat stepped spiral on tool roller axis to distribute, can reach not have and lay particular stress on phenomenon, can guarantee the stability of tool roller axis when work effectively, it is simple in structure, and volume is little, and required drive is little, and efficient is high;

2, owing to adopt the housing backplate, the one, for the stalk of pulverizing provides the passage of a derivation, it is scattered in the field equably; The 2nd, prevented effectively to fly out when knife section from coming off and hurted sb.'s feelings;

3, because blade adopts tulwar shape, and bent angle is 45 degree, and blade is arranged on the blade both sides, so when work, can vertically cut simultaneously and transverse cuts.
